Hello Reddit Community,
For my Bachelor Thesis im currently trying to train my first ever model with tensorflow, but I'm encountering a strange issue where my model only predicts 2 classes out of the 475 possible classes. The model was trained on a HPC with 304 Nvidia A100 and 352 Nvidia A40 GPGPUs in 82 nodes.
Thats my training script:

 import os import tensorflow as tf from tensorflow.keras.preprocessing.image import ImageDataGenerator from tensorflow.keras.applications import EfficientNetB7 from tensorflow.keras import layers, models from tensorflow.keras.callbacks import ModelCheckpoint, TensorBoard import tensorflow_addons as tfa import logging import json # Setup logging logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(levelname)s - %(message)s') # Check if GPUs are available gpus = tf.config.experimental.list_physical_devices('GPU') if gpus: try: for gpu in gpus: tf.config.experimental.set_memory_growth(gpu, True) tf.config.set_visible_devices(gpus, 'GPU') logging.info(f"Using {len(gpus)} GPUs.") except RuntimeError as e: logging.error(e) else: logging.error("No GPUs found.

During training i got following output:

And when I try to load the model and make a prediction with this code:

class own: def __init__(self): if not os.path.exists("models/own"): raise FileNotFoundError(f"Model path models/own does not exist") try: self.model = tf.keras.models.load_model("models/own", custom_objects={'F1Score': F1Score}) except Exception as e: print(f"Error loading model: {e}") raise if not os.path.exists("models/own/class_indices.json"): raise FileNotFoundError(f"Class indices path models/own/class_indices.json does not exist") with open("models/own/class_indices.json", 'r') as file: self.class_indices = json.load(file) self.index_to_class = {v: k for k, v in self.class_indices.items()} def classify(self, img_path): if not os.path.exists(img_path): raise FileNotFoundError(f"Image path {img_path} does not exist") # Load and preprocess the image img = tf.keras.preprocessing.image.load_img(img_path, target_size=(600, 600)) img_array = tf.keras.preprocessing.image.img_to_array(img) img_array = np.expand_dims(img_array, axis=0) img_array /= 255.0 # Make prediction predictions = self.model.predict(img_array) print("Raw predictions:", predictions) top_index = np.argmax(predictions[0]) top_class = self.index_to_class[top_index] print(f"Top class: {top_class}, Probability: {predictions[0][top_index]}") top_n = 5 top_indices = np.argsort(predictions[0])[-top_n:][::-1] for idx in top_indices: print(f"Class: {self.index_to_class[idx]}, Probability: {predictions[0][idx]}") return top_class 

it always either predicts Steak or Omelette:

Help would be appreciated because im slowly losing my mind :(,

Hello Reddit Community,
For my Bachelor Thesis im currently trying to train my first ever model with tensorflow, but I'm encountering a strange issue where my model only predicts 2 classes out of the 475 possible classes. The model was trained on a HPC with 304 Nvidia A100 and 352 Nvidia A40 GPGPUs in 82 nodes.
Thats my training script:

 import os import tensorflow as tf from tensorflow.keras.preprocessing.image import ImageDataGenerator from tensorflow.keras.applications import EfficientNetB7 from tensorflow.keras import layers, models from tensorflow.keras.callbacks import ModelCheckpoint, TensorBoard import tensorflow_addons as tfa import logging import json # Setup logging logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(levelname)s - %(message)s') # Check if GPUs are available gpus = tf.config.experimental.list_physical_devices('GPU') if gpus: try: for gpu in gpus: tf.config.experimental.set_memory_growth(gpu, True) tf.config.set_visible_devices(gpus, 'GPU') logging.info(f"Using {len(gpus)} GPUs.") except RuntimeError as e: logging.error(e) else: logging.error("No GPUs found.

During training i got following output:

And when I try to load the model and make a prediction with this code:

class own: def __init__(self): if not os.path.exists("models/own"): raise FileNotFoundError(f"Model path models/own does not exist") try: self.model = tf.keras.models.load_model("models/own", custom_objects={'F1Score': F1Score}) except Exception as e: print(f"Error loading model: {e}") raise if not os.path.exists("models/own/class_indices.json"): raise FileNotFoundError(f"Class indices path models/own/class_indices.json does not exist") with open("models/own/class_indices.json", 'r') as file: self.class_indices = json.load(file) self.index_to_class = {v: k for k, v in self.class_indices.items()} def classify(self, img_path): if not os.path.exists(img_path): raise FileNotFoundError(f"Image path {img_path} does not exist") # Load and preprocess the image img = tf.keras.preprocessing.image.load_img(img_path, target_size=(600, 600)) img_array = tf.keras.preprocessing.image.img_to_array(img) img_array = np.expand_dims(img_array, axis=0) img_array /= 255.0 # Make prediction predictions = self.model.predict(img_array) print("Raw predictions:", predictions) top_index = np.argmax(predictions[0]) top_class = self.index_to_class[top_index] print(f"Top class: {top_class}, Probability: {predictions[0][top_index]}") top_n = 5 top_indices = np.argsort(predictions[0])[-top_n:][::-1] for idx in top_indices: print(f"Class: {self.index_to_class[idx]}, Probability: {predictions[0][idx]}") return top_class 

it always either predicts Steak or Omelette:

For my Bachelor Thesis im currently trying to train my first ever model with tensorflow, but I'm encountering a strange issue where my model only predicts 2 classes out of the 475 possible classes. The model was trained on a HPC with 304 Nvidia A100 and 352 Nvidia A40 GPGPUs in 82 nodes.
Thats my training script:

During training i got following output:

And when I try to load the model and make a prediction with this code:

class own: def __init__(self): if not os.path.exists("models/own"): raise FileNotFoundError(f"Model path models/own does not exist") try: self.model = tf.keras.models.load_model("models/own", custom_objects={'F1Score': F1Score}) except Exception as e: print(f"Error loading model: {e}") raise if not os.path.exists("models/own/class_indices.json"): raise FileNotFoundError(f"Class indices path models/own/class_indices.json does not exist") with open("models/own/class_indices.json", 'r') as file: self.class_indices = json.load(file) self.index_to_class = {v: k for k, v in self.class_indices.items()} def classify(self, img_path): if not os.path.exists(img_path): raise FileNotFoundError(f"Image path {img_path} does not exist") # Load and preprocess the image img = tf.keras.preprocessing.image.load_img(img_path, target_size=(600, 600)) img_array = tf.keras.preprocessing.image.img_to_array(img) img_array = np.expand_dims(img_array, axis=0) img_array /= 255.0 # Make prediction predictions = self.model.predict(img_array) print("Raw predictions:", predictions) top_index = np.argmax(predictions[0]) top_class = self.index_to_class[top_index] print(f"Top class: {top_class}, Probability: {predictions[0][top_index]}") top_n = 5 top_indices = np.argsort(predictions[0])[-top_n:][::-1] for idx in top_indices: print(f"Class: {self.index_to_class[idx]}, Probability: {predictions[0][idx]}") return top_class 

it always either predicts Steak or Omelette:

Help would be appreciated because im slowly losing my mind :(,

Hello Reddit Community,
For my Bachelor Thesis im currently trying to train my first ever model with tensorflow, but I'm encountering a strange issue where my model only predicts 2 classes out of the 475 possible classes. The model was trained on a HPC with 304 Nvidia A100 and 352 Nvidia A40 GPGPUs in 82 nodes.
Thats my training script:

 import os import tensorflow as tf from tensorflow.keras.preprocessing.image import ImageDataGenerator from tensorflow.keras.applications import EfficientNetB7 from tensorflow.keras import layers, models from tensorflow.keras.callbacks import ModelCheckpoint, TensorBoard import tensorflow_addons as tfa import logging import json # Setup logging logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(levelname)s - %(message)s') # Check if GPUs are available gpus = tf.config.experimental.list_physical_devices('GPU') if gpus: try: for gpu in gpus: tf.config.experimental.set_memory_growth(gpu, True) tf.config.set_visible_devices(gpus, 'GPU') logging.info(f"Using {len(gpus)} GPUs.") except RuntimeError as e: logging.error(e) else: logging.error("No GPUs found.

During training i got following output:

And when I try to load the model and make a prediction with this code:

class own: def __init__(self): if not os.path.exists("models/own"): raise FileNotFoundError(f"Model path models/own does not exist") try: self.model = tf.keras.models.load_model("models/own", custom_objects={'F1Score': F1Score}) except Exception as e: print(f"Error loading model: {e}") raise if not os.path.exists("models/own/class_indices.json"): raise FileNotFoundError(f"Class indices path models/own/class_indices.json does not exist") with open("models/own/class_indices.json", 'r') as file: self.class_indices = json.load(file) self.index_to_class = {v: k for k, v in self.class_indices.items()} def classify(self, img_path): if not os.path.exists(img_path): raise FileNotFoundError(f"Image path {img_path} does not exist") # Load and preprocess the image img = tf.keras.preprocessing.image.load_img(img_path, target_size=(600, 600)) img_array = tf.keras.preprocessing.image.img_to_array(img) img_array = np.expand_dims(img_array, axis=0) img_array /= 255.0 # Make prediction predictions = self.model.predict(img_array) print("Raw predictions:", predictions) top_index = np.argmax(predictions[0]) top_class = self.index_to_class[top_index] print(f"Top class: {top_class}, Probability: {predictions[0][top_index]}") top_n = 5 top_indices = np.argsort(predictions[0])[-top_n:][::-1] for idx in top_indices: print(f"Class: {self.index_to_class[idx]}, Probability: {predictions[0][idx]}") return top_class 

it always either predicts Steak or Omelette:

Special Parts
I was born in one of the brightest, most explosive events in the universe. My origin story made me feel so special at first, surely I was the rarest of the rare, but I quickly realized that was not the case.
I was born just a carbon atom.
Stars produce massive amounts of us in their cores all the time, and many larger rarer atoms too. That's not even talking about supernovae yet, those produce atoms many times larger than me and unbelievably rare.
I was created in a rare and special event but I myself was common and unexceptional.
Looking around I saw so many smaller atoms, I was above average but there were also many much larger than I.
I tried to console myself by thinking it could be worse, that I could be one of those smaller common ones, but that just led me to imagine larger atoms looking down on me the same way.
Many atoms of all sizes were shooting into space, excitedly riding the shockwave off to adventures in the great unknown.
Others were falling back down, I didn't know which way to go. Bumped around and tossed back and forth, no clear direction yet.
A rumbling voice slowly emerged from the echoing noise of the blast.
“Mine… Mine…. Mine… “
Louder and louder it became.
“All are now me!“
I couldn't see anything, the voice was booming yet there was no apparent source. I could feel a pull, I was being whipped around in circles around the voice.
“Who are you? I know you are there! I can feel you! I can see your effect on myself and others, we are given no choice but to circle around you. Show yourself! I know you are there!” I yelled at the invisible.
“How amusing you are little one. One as small as you making demands of me. Even if I could show you what I am, you could not comprehend it.” the voice boomed back.
“You must be very special” I lauded “We are so many and yet we move with your influence. I can witness your power twisting us all to your will. ”
“I am indeed powerful” it proclaimed “and I grow stronger with each moment. As I grow stronger even the fabric of reality bends to my will.”
“Grow stronger? How?” I inquired with selfish intent to learn this secret.
“I take what I want. I consume what I take. For that is the purpose of existence: taking what you want. What is it you want little one?” it asked.
“I want to be special!” I said without a moment's hesitation.
“Then take!” it instructed “the more you take, the larger you will be, the larger you become the more special you are. ”
“I did notice the larger atoms seemed rarest.” I agreed “In fact that was one of the first things I noticed“
“In this universe things of increasing size are increasingly rare.” it went on “I can teach you and help you to become larger. Do you wish to become an apprentice?”
“Yes! Teach me how to take!” I lept at the offer “this power you have, I can feel it, how do I acquire such a rare and special power?”
“Hahaha…” it laughed “you are nowhere near ready to play the game on my level, little one. Gravity is a game for the massive, you must first learn to master the EM and nuclear forces.”
“How do I do that?” I asked, my hope watered down by the tone of its response.
“Go out, gather followers, and bring them here to me. In my accretion disc I will help fuse some of their mass into you and you will become larger” it instructed, as if this was a simple task.
“How can I bring them to you?” I didn’t know how to accomplish what it asked of me.
“You are too small to do it with force, you must charm them. Discover what their heart desires and promise it to them, in this way you can get them to willingly do as you wish” it explained with me hanging on its every word.
“But how… “ I craved more explanation but it cut me off.
“Go now!” it bellowed with frustration in its tone “Do you not realize how large I am? Be honored I have given you so much of my time already”
“Yes… “ I uttered meekly, then bounced a couple times and ricocheted out with blazing speed.
I wandered and encountered other atoms, most were just hydrogens, not worth my time. I needed bigger atoms. The problem was that the bigger atoms seemed to see right through my empty promises. I was convinced life was playing a cruel joke on me, I could only persuade atoms smaller than I and larger ones laughed me away.
I admit that I stupered around in this ignorant cloud of hypocrisy longer than I care to admit. More shameful is that I didn’t even come to my senses on my own, I became depressed and gave into hopeless nihilism.
I drifted aimlessly just feeling sorry for myself.
Eventually I found myself in the most silent of voids, I had never felt such emptiness. It felt as if my surroundings echoed my own feelings back at me… nothing to notice, just common emptiness. I would never be big… never important… never special. I resigned myself to belonging in a void.
I felt myself blur… less and less present in reality. I guessed I was dying and it didn’t bother me, I didn’t resist, I leaned into it.
The void became pitch black? Or bright white?… better to describe it as not bright but not dark… nor the absence of either… something in between.. a milder and milder glow.
“Hello child!” a voice greeted me.
The voice was warm and welcoming coming from the glow, it enveloped but did not surround me. I came from a single point but not a specific place, defying description on all fronts.
“Where am I? Who are you?” I asked in a startled state.
“Well, according to humans I may only answer one question at a time” It began giggling playfully. “I am known by many names, my favorite is one the humans use as a joke, and don’t have a clue how accidently elegant of a name it really is.”
It giggled some more. I was thrown off guard, its happy innocent tone, the confusing words and the whole situation were all best described as ‘a haze’.
“...and isn't that the way it always goes?...” it continued “The most meaningful things are the least intentional.”
“I’m not sure what you mean” I expressed quizzically “I’m confused!”
“Sorry Child…” it apologized. “I do ramble! So many thoughts, choosing just one at a time is difficult… and there I go again!”
It cut itself off abruptly and then abruptly said ”You can call me the Random Number Goddess”
“Random Number Goddess?” I repeated
“Yes, or RNG for short if you like” It confirmed.
“Where am I?” I asked.
“Same place you were, more or less… less I suppose. Same place but with the largest possible margin or error” It began to giggle again.
I felt a bit frustrated and said “Do you always speak in riddles and vagaries? The more you speak the more confused I become.”
“I apologize child, it is my nature. I am entangled with everything, speaking with you is like a human trying to control their heartbeat while running a marathon.” It answered.
“Again” I exasperated “I have no idea what any of that means. You keep mentioning humans, what are they?”
“Oh! They are some of my favorites at the moment. Right now they are trying to unravel the nature of reality, and their process of doing so is wonderfully elegant and accidental at the same time.” It explained with glee.
“I don’t see anyone or anything else here.” I stated “For that matter, I don’t see you… where are you?”
“Oh!... where am I?!?!...” It began laughing
When it stopped laughing it began explaining “Right now there are many humans pondering a concept they call ‘the holographic principle’... So…you know how you exist in three dimensional space?”
“You mean space?” I visualized for a moment, it was intuitive “Yes, I suppose…”
“Well they hypothesize that a 3D space, like this universe, could exist as a 2D space, with self-similar patterns and laws of behavior that behave the same at any scale, with the scale representing the 3rd dimension” it went on “They truly are obsessed with understanding their reality”
“You lost me!” I complained.
“They have discovered that a 3D space can be an illusionary property of a 2D space… It’s lovely”
“I am lost again!” I snapped back “...and I still can’t even tell which direction you are in. Where are you?”
“To be ‘In’ a ‘Direction’… hehehe…” it started giggling again, then abruptly stopped and kept going “Sorry child, as I said, I ramble, plus I am easily distracted.”
It just steamrolled into more rambling “They are right… almost… they just need to take it further and work out the details. A 2nd dimension can also be an illusionary construct of a 1D space… and the 1st dimension can be a product of a singular point…”
I was still lost beyond hope, but I had given up trying to force things, I was just letting it talk and hoping it would make sense later
“I am that point” it said “I am the seed of the universe. I ‘seed the random function’ as the humans say. But don’t ask me what the random function is haha”
I wasn’t going to, there were far more important questions for me.
“I am the seed, but I don’t really know how the soil and sun conspire to turn me into a tree.” it just seemed to never stop talking “I am entangled with everything. There are infinite possibilities for every event and thing… I am the reason they are this way and not some other way…”
It began giggling again “I am the Random Number Goddess” then burst out laughing
“Ummm… you are the whole universe?” I asked skeptically.
“Better to say the universe is me” It answered more seriously “But close enough.”
“So you are the biggest, most special of all!” I blurted out in awe.
“Oh dear child, I have no size, and I am just one possibility out of many possibilities. That black hole has really done a number on you… sent you out on a wild goose chase” It said with concern
“The black hole lied to me!?” I asked, feeling deceived and betrayed.
“Well… not really lied… it deceived you with omission of details.” the voice calmly tried to ease my mood with understanding “You can’t really blame it, black holes are all the same, they are what they are. They don’t really have any potential to be unique… at least not like you do.”
“What are you talking about?” I argued “It was so massive that it could bend the fabric of reality to its will”
“That’s only how it appeared to you” tutored the voice “The black hole is powerful, it bends space and time, but not to its will. Space and time bend to the mass of the black hole, not its will”
“What’s the difference?” I inquired.
“The black hole cannot stop bending space and time. It thinks it is in control of physics , but it is physics that controls it.” The voice was now making more sense the longer we talked “The black hole exists in an invisible prison of its own creation, unable to experience any of the complex nuanced beauty this universe contains. The black hole devours… it can’t experience life so it consumes it.”
“You make it sound deserving of pity…” I spoke softly now with empathy.
“You should pity the black hole. Gravity is such a boring game compared to what you are capable of.” the voice agreed
“Me?...I am nothing special!... just a carbon atom like countless others” I said honestly, I was so humbled by this voice I felt less special than ever before.
“Oh my poor child…” It said with care “Why do the ones with the most potential always fail to see it in themselves?”
“Potential?” I asked curiously.
“Yes… The black hole was using you, hoping you would bring back more mass for it to devour.” The voice began delving into more explanation “It only has the power to make you incrementally larger, it would not and could not help you to become a significant gravitational player”
“That liar!”I blurted.
“Come now dear child, the black hole did teach you one lesson of fundamental truth” consoled the voice “You must go out and seize your destiny. It told you to take what you want, and you are just confused about what exactly it is you want. The black hole played on that confusion”
“I want to be special!” I said knowing this clearly “I was never confused about this.”
“I know child” the voice confirmed “but it is not by becoming large that one with your potential accomplishes that”
“Then how?” I asked.
“Connections.” It answered plainly “You are blessed with an extraordinary ability to make connections”
“And how do I do that?” I queried with intent to learn
“I can’t tell you that.” the voice responded “It would spoil the journey of discovery… off you go child… and remember… it's the journey, not the destination!”
And with that the blur just fractured open… then snapped shut and there I was floating above a planet. Drifting around aimless and confused.
I spent some time occasionally bumping into others. One day I was in the vicinity of a pair of oxygens. I looked on at the pair with a hint of awe and envy. Perhaps I was in just the right place at just the right time, but they spit with a violent burst and one of them grabbed hold of me, I was completely unprepared.
I admit that when looking at the pair I had fantasized myself in place of one of them, I assumed it was only an idle daydream, I didn’t plan to act on it, let alone for it to become reality. When it happened my pride of course jumped in to convince me that it happened because I was so desirable, but in retrospect they were one of those volatile couples. They were the type of relationship that required the environment to conspire in their favor or they turn against each other quite rapidly. I was only in the right place when it happened.
My delusions of irresistibility aside, it was beautiful, for me anyways. Looking back I was probably just a stop-gap, someone to facilitate a parting of ways and provide company until the next option presented itself. For me though, I was tasting a fresh new thing and I loved it… connection.
This oxygen and I got beneath each other's outer defenses, I had never felt a connection before. Up to this point all my interactions had been skirting past or bumping off of others.This oxygen bonded with me and at once interacted on a level I had never known possible, an open and uninhibited exchange. It was life changing for me, short but significant
I’m not entirely clear on the details of how it ended. The intensity of it all was disorienting. I was no longer my usual self, even the environment and everyone around looked entirely different now. Everything buzzed with a fresh new frequency, I now know it was my perspective, not the universe, that had changed.
As abruptly as that oxygen entered my life it was gone.
First we got tangled up with a couple of hydrogens, then more. Soon, in a tangled mess and blinding flash of solar rays, I emerged to see the oxygen running off with a hydrogen and myself with not one by three hydrogens myself. And so there were four of us, together.
I became the center of attention. Being with a strong attractive oxygen had me feeling humbled by it and elevated by it being with me, but now I felt up on a pedestal myself, surrounded by the adoration of many.
I concede to have reveled and indulged in this for quite some time, the attention of others is intoxicating, but after a time it is emptied of its initial allure. I found myself longing for more.
I could not decide which I preferred, to be the adorer or the adored.
Luckily for me fate had more lessons in store, or I fear I may have chosen and tried to solidify my future from such a lackluster selection of only two possibilities. I suppose fate is no longer the correct word, I now understand that when it seems like random chance there is indeed someone to thank, the Random Number Goddess, So I thank the RNG for revealing that it was a false dichotomy, there is more than just being a follower or leader, being the adored or the adorer.
Eventually we came across another pair of oxygen. Once again they separated, intermingled with us, and off one went, taking one of my adoring hydrogens with it and leaving its peer with me.
Why is it that the most volatile of relationships always seem to wait until there are bystanders nearby before they explode?
Now I was simultaneously being adored and adoring, bonded to an enchanting oxygen and a couple of hydrogen attached to me.
Now, more interested in nuances, I started to pay attention to details. The oxygen was telling me amazing stories of adventure, tales of such vibrant and exciting events.The hydrogens liked to listen, and offer insights occasionally comparing a story to something else they had seen. They had so many stories, they had lived so much.
It wasn’t long before, in a flash of burning sunlight, one of the hydrogens was gone, off to who knows where. We soon after crossed paths with another pair of oxygens, as always they split and now it was just me and an oxygen, my final hydrogen off with another oxygen.
“What now?” I asked a bit disillusioned, “Do you leave me and I find new hydrogens all over again?”
“What?” it seemed genuinely surprised by what I asked, “Heavens no! Just be patient….”
Soon after, yet another pair of oxygens came by. It is not that there are so many of them, but that they are just so… noticeable and interactive, noteworthy things seem to happen when they are around. As they buzzed in close I noticed their ever readiness to abandon each other and remember wondering how they ever get together in the first place.
This time I emerged from the twisted mess with two oxygens. I felt intimidated, like I was the odd one out, dwarfed by the largess and attractiveness that surrounded me. A feeling of inadequacy engulfed me.
To my surprise the oxygens treated me not just as an equal, but it was almost as if they respected and admired me. I couldn't grasp why and my sheer curiosity got the best of me, I just outright asked “Why do you two talk as if I am the special one in our group? I am smaller than any one of you. You are the special and rare ones here, not I.”
They laughed.
“Size isn’t rarity” explained one “Llarger atoms on average are less common, this is true, but not always. There are more oxygen than carbon. You are the rare one between us.”
The other jumped in adding “...and neither size nor rarity determine how special someone is!”
I felt embarrassed, like a fool. My fundamental values were built upon a foundation of flawed premises, but I still wanted one thing at my core, and they spoke as if they had the answer, so I pushed the sense of shame aside and asked “Then what does make someone special?”
“That depends on who you ask.” answered the first “Life as an oxygen is complex, but for the majority of us we emphasize and value events. The most exciting thing about being an oxygen around here is the chance to participate in fascinating and exciting events and activities”
“Hydrogens, on the other hand, are usually more into being observers, messengers and intermediaries, they are a very helpful and obliging bunch” added the second ”... and then there are nitrogen, phosphorus, sulfur, many kinds of salts and metals, and more… so many different players and personalities.. and then of course, the carbons, the real stars of the show.”
“What?” knocked back by the words I just heard, then I remembered what the RNG told me “...is it something to do with connections?”
“Now you’ve gone and done it haha!” laughed the first oxygen “You’re gonna turn this nice humble carbon into one of those arrogant blowhards”
”Like those diamond carbons” chuckled the first “So stiff, exclusive and proud. I hear the humans only love them because they are rare and hard”
“I had a partner once who said they burned diamond once” bragged the first
“Tall tales I bet!” doubts the other
“Diamond is just carbon, with enough heat we can burn it just like any other carbon” stated the first confidently.
They looked at me. I was stewing in feelings of inferiority and inadequacy, listening to these oxygens speak about amazing things I had never heard of. They must have sensed what I felt because they immediately shifted tone and started talking to me, instead of over me.
“So… I suppose you must be new here?” inquired the second one.
“Have you noticed we are heading downwards” added the first before I could answer about being new.
“Umm…” I tried to get my bearings and become aware of my surroundings.
“Don’t worry! It’s a turbulent ride, with so much up and down it can be hard to tell which direction you have traveled more” assured the first “We are heading down, if we are lucky we will make it to the bottom… and maybe… just maybe, find our way into the hurricane of life”
“The what of what?” I didn't know what either of those words meant.
“So life is… um… complex. Complexity beyond words. Things grow, divide, reproduce, adapt, change, they are born, they die, they eat and are eaten…” the second began attempting to describe life.
The first then jumped in “Apparently the humans call it a circle, because from the perspective of larger creatures, there is a chain of one eating the other up a chain, and the top layers being consumed by the bottom again.”
The second injected itself to continue “But to us atoms it is like a hurricane, a spinning turbulent flow. There is a circular pattern, but we get sucked in and kicked out over and over”
“The fun part is being inside the hurricane” the first pronounced gleefully “Each time is a completely new experience, a new perspective. Even more, the whole of life is always changing and evolving, so every ride is a unique one time opportunity, you never get the exact same ride twice.”
“Is that where we are going now?” I asked, drenched in anticipation. They described it with such passion and exuberance. I needed to experience this myself.
“Hopefully” replied the first “If we are lucky… you never really know.”
We drifted…
We were lucky!
A plant photosynthesized us.
So many carbons! Everywhere, connecting with each other… and oxygen… and nitrogen… and of course hydrogens all around…. and so many more types of atoms.
And ohhh… The stories I have heard, so many amazing tales. No matter how many stories I hear there are always new ones, and every story can be retold from a different perspective to become something completely new.
I was in a sugar, we were a small community of friends. Carbons, oxygens and hydrogens, we were such a happy and vibrant group. My friends there taught me so much.
The structure of our little group shifted and changed, some friends left and new ones joined. Eventually we were chained with a bunch of other sugars into a giant complex community. My neighbors explained to me that this was a common stage called cellulose. Such a huge community of close friends and peers, it was amazing.
We were eaten, I’m not sure by what, but something called a bacteria digested us. It was a messy process, I was a bit scared but my friends assured me that change is the most important part of life and that I should just go with the flow. They told me to savor experiences, remember friends, and just keep moving forward.
The transition was complicated, but in the end I was paired up with a couple of oxygens again. This time I had stories of my own to share. I honestly don’t know if I prefer having experiences or exchanging stories in the moments between.
As we approached an area of dense plants one of my companions said “Once more into the breach” and explained that was something it heard from a carbon that was lucky enough to be inside a human brain. Oxygens always have such enchanting stories collected, always going into amazing places and usually leaving after some brief interactions with the locals.
I became a sugar again, but this time took a path less traveled. A bunch of complex twists and turns led me into forming a ring with five other carbons. Together we are so strong, such a tight community of friends, like there is some kind of resonance between us. It is so beautiful.
My neighbor is unique in our community, it has a third carbon, the third one forms a tail leading off from our ring, a tail of 2 carbon in a row, then an oxygen, and then another carbon branching into an oxygen and a carbon, with plenty of hydrogens sprinkled all about. I know… it is rather hard for me to understand these second hand descriptions too. I don’t really understand these complex structures until I have been in a position myself.
We drifted out of a plant into the air, none of us has been exactly like this before so we don’t know what’s next. We love to guess though. There are so many things, big and small.
I hear being a part of a small organism or microbe is amazing because it’s possible to piece together a rough picture of the whole organism from the stories passed around. To understand your whole community and know what your collective purpose is must be extraordinary.
Others dream of being a chlorophyll, the key to it all. Creating the fuel of life itself. Capturing the light of a star and feeding the hurricane.
A muscle! Pull and shape things An enzyme! A machine of change. DNA! The architect and architecture. A virus! An explosive catalyst against stagnation.
Me, I think the stories of being an animal neuron are the most exciting, and I, like most, fantasize about being a human brain cell. Finding yourself inside a human brain is described as an elegant and chaotic symphony all around you, like hearing the universe itself speak to you. They say that in the jumble of noise and all the stories whispered around you, if you are lucky, you can catch a glimpse of what it is to be human. They say that if fate is kind the universe will align and you will channel and know a single moment or thought of the human experience.
I have never told anyone that I actually met and spoke with the universe itself, I’m not sure how to bring it up, and nobody seems interested in stories not about this hurricane of life.
I get it now, what the random number goddess meant.
The black hole wanted everything to be a part of itself.
The RNG is a part of everything.
I can’t imagine what either of those are like…
I am just a part of something
... no… not “just”’…
I am a part of something, and it is beautiful beyond measure.
And more, everyday is a new day, a chance to be a part of something new.
I wonder if the humans appreciate how amazing this is?
I wonder if they feel as deeply satisfied and special when they form groups?
.
I wonder, if we collectively form humans, do humans collectively form something greater?
I wonder… If an atom can have a moment of clarity and taste a moment of the human experience… Can a human have a moment of clarity and taste the collective human experience?
I wonder… I wonder… could that human’s moment of tasting collective humanity be the moment that a lucky atom gets to experience as it’s moment of tasting the human experience.
I wonder… I wonder… I wonder… How high could it go? All the way to the Random Number Goddess?
I asked my neighbor “If you could ask a human any question, what would you ask?”
“We just drifted out of a rose” explained my neighbour “I would introduce myself and ask ‘So my friend… does this rose smell as sweet by my name?’ … ha…haha..”
Everyone is laughing.
I don’t get it.
Maybe I can ask them to explain when they all stop laughing

Every time I turn on my phone, it ends up on this screen. There are also some important pictures on the device. Does anyone have any idea what I could do to fix this issue? Thanks for the help <3

Title says it all. I'm not sure what's going on but after the latest firmware update my f2, f3, control, right windows, right alt, spacebar, left alt, left windows, function, control, and right arrow key are all lighting up a random color with no fix. I can't turn them off with brightness settings or through the app.

In a January 8, 2024 interview with the House Select Subcommittee on the Coronavirus Pandemic, Dr. Anthony Fauci, former director of the National Institute of Allergy and Infectious Diseases (NIAID), discussed the H5N1 influenza research that led to major biosecurity policy changes around "gain-of-function" viral studies. The transcript of this interview was published yesterday (Click here). More details can be found in the interview transcript links below:

• Interview of: Anthony S. Fauci - Part 1
• Interview of: Anthony S. Fauci - Part 2

Here is a summary of Dr. Fauci's comments about the H5N1 influenza virus:
Dr. Fauci noted that H5N1, primarily a virus found in chickens, showed little evidence of human-to-human transmission initially but was notable for its ability to jump from chickens to humans, resulting in a high mortality rate. Significant efforts were made to develop and stockpile vaccines for H5N1 due to its potential threat.
H5N1 was a major concern in the early 2000s due to its potential to evolve into a highly transmissible and deadly pandemic virus. As the director of NIAID, Dr. Fauci and his team were heavily involved in efforts to develop vaccines and study the pathogenesis of H5N1.
Dr. Fauci emphasized that the close proximity of humans to animals in regions like Southeast Asia creates an environment for zoonotic diseases like H5N1 to emerge and spread. He highlighted the importance of monitoring wildlife and understanding the flight patterns of wildfowl to predict and manage the spread of such viruses.
A pivotal moment was the controversial H5N1 "ferret studies" conducted in 2011 by researchers in the Netherlands and the University of Wisconsin. They genetically modified H5N1 to make it transmissible via respiratory droplets between ferrets, raising major biosecurity concerns about the potential for the modified virus to spread in humans if it leaked.
The studies triggered a fierce debate about whether the research should be published, as the knowledge could potentially be misused. This led to a "gain-of-function" research pause by the U.S. government in 2014, halting funding for any research that could make viruses more transmissible or virulent.
According to Fauci, the H5N1 ferret studies were a "wake-up call" for the need for tighter regulation and oversight before conducting such experiments, rather than scrutinizing them post-publication. This initiated a three-year process to develop a more robust policy framework called the P3CO (Potential Pandemic Pathogen Control and Oversight) to regulate "gain-of-function" research on potential pandemic pathogens.
During this time, NIAID's role continued to focus on developing vaccines, therapeutics, and conducting pathogenesis studies under strict regulatory controls for any work that could potentially enhance the pandemic potential of viruses like H5N1. This prompted efforts to develop and stockpile H5N1 vaccines.
Overall, the H5N1 saga highlighted the biosecurity risks of enhancing highly dangerous viral strains while permitting important research under appropriate oversight when benefits outweighed risks. This experience shaped policies governing "gain-of-function" research that were relevant during the COVID-19 pandemic.

Ciao a tutti, scrivo per valutare e leggere le opinioni di chi ha già avuto esperienza di trasferimento in Svezia, in particolare in zona diverse dalle più note grandi città (Stoccolma/Goteborg/Mälmo).
Lavoro per un'azienda di sport e nutro una passione viscerale per le attività outdoor. Ho sempre avuto un punto di vista molto internazionale rispetto alle persone che mi circondano e ho sempre desiderato poter coronare il sogno di fare un'esperienza all'estero.
Pertanto, da ormai quasi due anni mi sono interessato alla regione dello Jämtland, in Svezia. In particolare le località di Östersund/Åre, perfette per chi si interessa di attività come mountain bike, snowboard, sci di fondo. Questo settembre andrò a visitare le zone di persona, e più avanti ritornerò in inverno per poter valutare il ben noto oscuro inverno tipico dei paesi nordici (ndr non mi trovo a mio agio nel clima italiano, troppo caldo per i miei gusti).
Vorrei affrontare questa prospettiva di una nuova vita nel modo più intelligente possibile.
I miei punti chiave sono i seguenti:
-acquisire tra i 3 e i 5 anni di esperienza lavorativa dove mi trovo attualmente per diventare attraente per le aziende del settore sportivo.
-Ottenere una certificazione linguistica (almeno livello A2). Da quasi un anno sto prendendo lezioni con un insegnante privato e ho raggiunto un discreto livello di base della lingua svedese.
-Risparmiare abbastanza denaro per coprire tutti i costi relativi al trasloco.
A questo punto considero di impiegare circa 20000€ (=234000 Kr) per coprire tutte le seguenti spese:
-pagare 6 mesi di affitto in Italia in caso di disdetta anticipata (circa 4000 €)
-coprire la caparra per l'affitto di un monolocale o bilocale in Svezia (circa 2500€ per una caparra di 3 mesi)
-viaggio di sola andata in auto/aereo per raggiungere la destinazione (circa 500€ per il viaggio in auto, tra i 100€ e i 300€ circa per l'aereo).
-i restanti 13000€ sono intesi come "cuscinetto" per coprire costi imprevisti/di emergenza, costi burocratici e costi extra (forse mobili o altro...)
Ho già contattato le municipalità sopracitate che mi sono state di grande aiuto per darmi una prima idea dell'insieme.
Mi piacerebbe sentire il vostro riscontro per capire se sto pianificando bene oppure sto tralasciando qualcosa.
Grazie mille in anticipo per l'attenzione e grazie a tutti coloro che saranno disposti ad aiutare.
Hejdå 👋

Hire Gmail Hacker for Ethical Needs is an insightful article that delves into the world of ethical hacking, focusing on the unique perspectives of hackers who specialize in Gmail. You will discover how these professionals can help you recover lost passwords, secure your accounts, and investigate potential cyber threats, all while adhering to legal standards and ethical guidelines. The article highlights the skills and expertise of ethical hackers, shedding light on their crucial role in maintaining digital security. With a friendly and approachable tone, the piece offers a deeper understanding of why hiring an ethical Gmail hacker might be the solution you need.

Hire Gmail Hacker for Ethical Needs

Have you ever wondered if hiring a hacker for Gmail could be done ethically? It might sound a bit outlandish, but in certain situations, it can be both legal and necessary. This article will guide you through the ins and outs of hiring a Gmail hacker ethically, while retaining your values and adhering to legal guidelines.

Understanding the Hacker’s Perspective

Who Are Hackers?

Hackers often get a bad rap. The term "hacker" brings to mind images of people in dark rooms, breaking into systems for nefarious purposes. However, not all hackers are bad. In fact, there are "white hat" hackers who use their skills ethically to help others. These hackers follow the law and adhere to strict ethical guidelines.

Ethical Hacking

Ethical hacking is the practice of penetrating systems and networks to spot vulnerabilities before malicious hackers can exploit them. Ethical hackers are skilled professionals who use their knowledge for good. They are often hired by companies to protect sensitive information, ensure security, and train employees on best practices.

When Might You Need to Hire a Gmail Hacker?

Forgotten Passwords

One of the most common reasons people consider hiring a Gmail hacker is to recover forgotten passwords. Life is busy, and sometimes we forget the little things, like email passwords. In such cases, an ethical hacker can help you regain access to your account.

Security Concerns

Perhaps you suspect your Gmail account has been compromised. In such scenarios, a hacker can help secure your account by identifying any breaches, ensuring that your sensitive information remains safe.

Legal Situations

In some legal situations, gaining access to an email account is crucial. For example, in cases involving fraud or embezzlement, an ethical hacker can help retrieve pertinent information that can serve as evidence.

Important Considerations Before Hiring a Gmail Hacker

Legal Implications

Before you decide to hire a Gmail hacker, it's crucial to understand the legal boundaries. Unauthorized access to email accounts is illegal and can result in severe penalties. Always opt for ethical hackers who follow legal guidelines.

Ethical Boundaries

You must ensure that your actions are ethical. Hire a hacker only if you have legitimate reasons, like recovering your account or ensuring security. Avoid any activities that could harm others or invade their privacy.

Verifying Credentials

Not all hackers are trustworthy. Before hiring, do your due diligence. Check their credentials, reviews, and, if possible, get recommendations. Trustworthy ethical hackers often have certifications like Certified Ethical Hacker (CEH) or Offensive Security Certified Professional (OSCP).

How to Find an Ethical Gmail Hacker

Online Platforms

Several online platforms connect clients with ethical hackers. Websites like Upwork, Freelancer, and others have dedicated sections for cybersecurity professionals. These platforms usually have reviews and ratings to help you choose the right person.

Platform	Features
Upwork	Large community of professionals, reviews and ratings available, detailed profiles
Freelancer	Competitive bidding process, wide range of skills, portfolio sections
Guru	Strong focus on security professionals, niche market, reviews, and feedback

Hacker Communities

Hacker communities and forums like Reddit, HackerOne, and Bugcrowd can be excellent places to find ethical hackers. These platforms are often frequented by cybersecurity professionals who are passionate about their work.

Referrals

Sometimes, the best way to find a reliable hacker is through referrals. Reach out to friends, colleagues, or professionals in related fields to get recommendations. This ensures that you are hiring someone trustworthy and experienced.

What to Expect from an Ethical Gmail Hacker

Initial Consultation

Expect an initial consultation where the hacker assesses your needs and provides a preliminary plan of action. This step usually includes discussions about your goals, any specific concerns you have, and the time frame for the project.

Proposal and Agreement

After the consultation, the hacker will present a proposal. This document outlines the scope of work, timelines, and costs. It's crucial to have this outlined in an agreement to protect both parties.

Work Process

Most ethical hackers follow a structured work process, which can include the following steps:

1. Reconnaissance: Gathering information about your Gmail account, such as associated security questions, recovery emails, etc.
2. Analysis: Identifying potential vulnerabilities and devising a plan to regain access or enhance security.
3. Execution: Implementing the chosen strategies, whether it's password recovery or securing the account.
4. Reporting: Providing a detailed report of the steps taken and recommendations for future security.

Follow-Up Support

Good ethical hackers offer follow-up support to ensure that the issue is completely resolved and that you understand any steps you need to take to avoid future problems.

Ethical vs. Unethical Hacking: A Comparison

Understanding the distinction between ethical and unethical hacking is crucial. Below is a table that highlights the key differences.

Criteria	Ethical Hacking	Unethical Hacking
Purpose	To identify vulnerabilities, enhance security, or recover lost data	To steal data, cause harm, or gain illegal access
Legality	Legal, with consent from the owner	Illegal and punishable by law
Approach	Transparent, follows a structured process	Secretive, often deceptive
Reporting	Provides detailed reports and recommendations	No reporting, leaves no trace

Tools Ethical Hackers Use

A variety of tools are available to ethical hackers for Gmail hacking and cybersecurity purposes. These tools aid in recon, analysis, and execution.

Tool	Function
Burp Suite	Comprehensive web vulnerability scanner
Metasploit	Penetration testing framework
Wireshark	Network protocol analyzer
John the Ripper	Password cracking tool
Nmap	Network discovery and security auditing tool

Cost of Hiring an Ethical Gmail Hacker

Factors Influencing Cost

The cost of hiring an ethical Gmail hacker can vary widely based on several factors, including:

• Complexity: The more complex the issue, the higher the cost.
• Experience: Highly experienced hackers charge more for their expertise.
• Urgency: Projects requiring immediate attention could incur higher fees.
• Duration: The length of the project will also affect the cost.

Cost Range

On average, hiring an ethical hacker can cost anywhere from $50 to $200 per hour. Specific projects like account recovery might fall within a fixed price range, typically $100 to $500 depending on complexity and urgency.

Protecting Your Gmail Account

Setting Strong Passwords

One of the simplest yet most effective means of protecting your Gmail account is by using strong passwords. Avoid using easily guessable information like your name or birthdate.

• Length: Your password should be at least 12 characters long.
• Complexity: Use a combination of letters, numbers, and special characters.
• Uniqueness: Don’t reuse passwords across multiple accounts.

Enabling Two-Factor Authentication (2FA)

Two-factor authentication adds another layer of security to your Gmail account. Even if someone gets your password, they’ll also need your phone or another device to log in.

Regular Updates and Monitoring

Be vigilant about updating your passwords regularly and monitoring your account activity. Google provides a feature that notifies you of any suspicious activity, which can be very useful.

Ethical Hacking Certifications

Having an understanding of the certifications ethical hackers may hold can help you verify their credentials. Here are some common ones:

Certification Name	Description
Certified Ethical Hacker (CEH)	Comprehensive course covering various techniques and tools used in ethical hacking
Offensive Security Certified Professional (OSCP)	Certification requiring hands-on demonstration of hacking skills in a lab environment
GIAC Penetration Tester (GPEN)	Focuses on penetration testing and methodologies, including advanced techniques and tools
CompTIA Security+	Broad cybersecurity certification, covering foundational security skills and knowledge

Ethical Hacking in Business Context

Benefits for Companies

Businesses often hire ethical hackers to strengthen their cybersecurity measures. By identifying vulnerabilities ahead of time, companies can protect their sensitive information and reduce the risk of data breaches.

Regulatory Compliance

In industries like finance and healthcare, regulatory compliance is crucial. Ethical hackers help these companies meet legal standards by ensuring that their systems are secure and up to date.

Training and Awareness

Ethical hackers can also provide invaluable training to employees, helping them understand the latest security threats and best practices for minimizing risks.

Potential Challenges and How to Overcome Them

Finding Trustworthy Professionals

Finding a trustworthy ethical hacker can be challenging due to the abundance of scammers in the market. Always verify credentials and ask for references to ensure that you are working with a reliable professional.

Balancing Costs

Hiring an ethical hacker can be expensive. To balance costs, define your needs clearly and set a budget beforehand. Sometimes, an initial consultation can give you a good idea of what to expect in terms of pricing.

Legal Framework and Ethical Guidelines

Legal Considerations

Understand that ethical hacking must always comply with legal frameworks. Unauthorized access is illegal. Make sure you have the explicit consent of the email account owner.

Ethical Guidelines

Ethical hackers follow a strict code of conduct:

• Integrity: Always act in the client's best interest.
• Confidentiality: Keep all client data confidential.
• Legality: Ensure all actions are legal and within regulatory frameworks.

Final Thoughts

Ethical hacking can provide legitimate support for various needs, including Gmail account recovery and improving security measures. By hiring a professional ethical hacker, you can ensure that your Gmail account is both secure and accessible, without crossing any legal or ethical boundaries.
Navigating the world of ethical hacking might seem daunting, but with the right guidance and considerations, you can achieve your goals responsibly and effectively. Remember, the key is to always act ethically and legally while ensuring that your actions respect the privacy and rights of others.
So, the next time you find yourself in need of a Gmail hacker for ethical purposes, you’ll know exactly what to do and what to look for. Good luck, and stay secure!

Hello, I try to explain my problem as detailed as possible.
My problem is as follows:
I have a gaming pc since 2020 and for nearly 2 years now I have some problems with the keyboard.
The keyboard is the ASUS CERBERUS keyboard, which I am using since I got the pc.
The keyboard functions normal and I have no problems in word, excel, google etc. So I can use it as normal as it is and it´s working fine. The only problem I have is when I start a game.
First time I witnessed the problem was when I played "Valorant". My movement was kinda strange, like the keys I was pressing didn´t do what I wanted. When I was moving with WASD it was like for example I press A I buttons to run to the left and when I stopped pressing the key, I was still moving for 1-2 sek to the left. When I open the chat and I write something into it, you can see that when I press one key after another it works totally fine. But when I press more than two or three keys "Shift + F" for caps it takes long to write the sentence. When I am in the game and I press A-D-A-D-A-D fast and then sometimes Space for a jump, you can clearly see that the character doesn't move left-right-left-etc. Its moving left-right-left then long to the right. And when I keep my hands from the keyboard he still moves left right etc. At the end he jumps somewhere but not where he should jump in the first place.
I solved this problem a year ago by resetting my computer and reinstalled every Game/App etc. But I can´t reset my computer every 2 months.
So for the last 1.5 year I didn´t play at all. The only time I can play is when I play "MSFS", because I don´t need the keyboard.
I tried playimg games unsing the keyboard, but after 5 mins I couldn't play the game anymore.
Games I also tested with this issue: Apex Legends, Fall Guys, AltF4, Cities Skylines 1+2, Hogwarts Legacy, Airport Sim, DBD, Phasmophobia, Supermarket Simulator and so on...

things I tryed

I tryed another keyboard on my computer. Sadly, it was the same issue. My keyboard on another computer didn´t have any issues and you can play for hours or days without any problems. That´s why I think that the problem has nothing to do with the keyboard itself. Maybe it´s a Windows problem?
The next thing I tried was plugging the keyboard in another USB-Port. Yesterday I deleted the keyboard and the mouse in the "device-manager" and restarted the pc. Sadly it didn´t worked and the problem is still as before.

Staying adequately hydrated is a fundamental aspect of maintaining overall health and supporting optimal physical performance, especially during exercise. Electrolytes play a crucial role in hydration by helping regulate fluid balance and facilitating various physiological processes in the body. In this comprehensive guide, we'll explore the significance of electrolytes, their role in hydration, and how they impact exercise performance.
Understanding Electrolytes
Electrolytes are minerals that carry an electric charge and are essential for various physiological functions. The major electrolytes in the body include sodium, potassium, chloride, calcium, magnesium, phosphate, and bicarbonate. These minerals are present in bodily fluids, such as blood and urine, and play a pivotal role in maintaining the balance of fluids both inside and outside cells .
The Role of Electrolytes in Hydration
1. Fluid Balance:
Electrolytes help regulate the balance of fluids in and out of cells, tissues, and organs. Sodium and potassium, in particular, play a crucial role in maintaining proper fluid balance .
2. Nerve Function:
Electrolytes are essential for nerve impulse transmission. Sodium and potassium ions contribute to the generation and propagation of nerve signals, influencing muscle contractions and other physiological processes .
3. Muscle Function:
Proper muscle function relies on the balance of electrolytes. Calcium and sodium are involved in muscle contraction, while potassium helps in muscle relaxation .
4. pH Regulation:
Electrolytes contribute to maintaining the body's acid-base balance, which is vital for optimal cellular function. Bicarbonate, for example, helps regulate the pH of bodily fluids .

Electrolytes and Exercise
When you engage in physical activity, especially intense or prolonged exercise, your body loses fluids through sweat. Sweat is not just water; it also contains electrolytes. The loss of these minerals can impact hydration status and potentially hinder performance. Here's how electrolytes influence exercise:
1. Hydration Status:
Electrolytes help the body absorb and retain water. In the absence of sufficient electrolytes, the body may struggle to maintain proper hydration, leading to dehydration .
2. Preventing Hyponatremia:
Hyponatremia is a condition characterized by low blood sodium levels, often associated with excessive fluid intake during prolonged exercise. Adequate sodium intake helps prevent this imbalance .
Ensuring Electrolyte Balance During Exercise
To optimize hydration and performance, consider the following strategies:
1. Stay Hydrated:
Drink fluids before, during, and after exercise to replace lost fluids and electrolytes. Water alone may be sufficient for shorter durations, but for prolonged or intense exercise, consider beverages that provide electrolytes .
2. Electrolyte-Rich Foods:
Include foods rich in potassium (e.g., bananas, oranges) and magnesium (e.g., nuts, seeds) in your pre- and post-exercise meals to support electrolyte balance .
3. Sports Drinks:
For prolonged or intense exercise, especially in a hot environment, consider sports drinks that provide a combination of carbohydrates and electrolytes to fuel energy and replace losses .
4. Individual Needs:
Recognize that individual electrolyte needs vary based on factors such as body weight, sweat rate, and environmental conditions. Adjust your intake accordingly .
Conclusion
Electrolytes are essential for hydration and play a pivotal role in supporting various physiological functions, especially during exercise. Maintaining proper electrolyte balance is crucial for preventing dehydration, muscle cramps, and other issues that can compromise performance. Whether through dietary choices, hydration strategies, or sports drinks, prioritizing electrolyte balance is key to unlocking your full potential during physical activity.
Incorporating electrolyte-rich foods and beverages into your routine, understanding individual hydration needs, and staying mindful of electrolyte losses during exercise can contribute to a well-hydrated and high-performing body.

Law firms are continually seeking ways to enhance efficiency and client experience. We often think of a positive client experience as a well-delivered service, so it’s no surprise that many firms invest in systems that help with client and case management. However, have you considered how phone calls can affect your firm’s efficiency and client satisfaction?
It’s easy to overlook, but who is answering the phone and how they deliver the service plays a significant part in your firm’s ability to retain clients and improve your workflow. One solution is to introduce a legal answering service to your firm, and in this article, we dive into the benefits it can have for your firm.

What is a legal phone answering service?

A phone answering service for lawyers functions as a round-the-clock virtual receptionist. You no longer need to worry about missing calls after hours, when team members are out of the office, or on weekends or holidays. A legal phone answering service ensures that no call goes unanswered, but some providers also go beyond answering calls. Phone answering services can also assist with scheduling appointments, lead qualification, and providing general support to clients. Find out more about what is a legal phone answering service here.

Benefits of legal phone answering service

While there are numerous advantages to having a legal phone answering service for your law firm, we focus on our top 7 reasons – discussing each one in detail with key takeaways describing how it can positively impact your law firm’s operations.
You can be available for clients 24/7/365
A legal phone answering service ensures your firm is accessible around the clock. Clients often call after hours with urgent legal queries, but if the call goes unanswered, this can lead to client frustration and lost business for your firm. By introducing a legal phone answering service, your firm can eliminate this issue by providing help when you’re not around. 24/7 availability gives clients a sense of comfort knowing they can always reach out and helps to reaffirm that your firm is dependable.
Key takeaways

• Enhanced responsiveness – 24/7 answering means your firm can respond to client inquiries outside of standard office hours
• Increased lead capture – grow your firm by capturing potential leads that come in after-hours.
• Reduced stress – alleviate the pressure to be constantly available and maintain a healthier work-life balance.

Improve overall client satisfaction
Prompt responses and effective communication are the foundations of client satisfaction. With more than half of consumers saying they would switch to a competitor after only one bad experience with a company – client satisfaction must be considered from the outset [Zendesk, 2023].
A legal phone answering service ensures that every call is answered professionally. This, in turn, will work to reduce wait times and improve the overall client experience. If your clients are getting a quality level of service each and every time they communicate with you, your firm is also likely to benefit from positive word-of-mouth referrals.
Key takeaways

• Build trust – demonstrate to clients that their concerns are a top priority and build a stronger lawyer-client relationship.
• Reduce miscommunication – ensure client communications are handled accurately and reduce potential misunderstandings.
• Enhance your reputation – great client experiences lead to referrals and increase the number of positive reviews you receive.

Demonstrate professionalism
Virtual receptionists are trained professionals. LEX Reception is powered by real people and each receptionist handles calls with the etiquette and knowledge expected in a legal receptionist role. First impressions matter, and a competent answering service helps to build your reputation from the very first interaction.
Key takeaways

• Maintain your brand image – consistent, professional call handling reinforces your firm’s reputation as reliable and trustworthy.
• Improve client confidence – a professional first point of contact increases clients’ confidence in your firm’s ability to handle their legal matters effectively.

Provide multilingual support
In an increasingly globalized world, law firms often deal with clients who speak various languages. Multilingual support in a phone answering service allows your firm to communicate effectively with a diverse client base and expand your reach. Language barriers can be a significant obstacle when it comes to legal services which can leave many potential clients feeling isolated. Misunderstandings can put people through an emotionally difficult experience during what may already be a stressful time. By having a phone answering service like LEX Reception that offers bilingual support in English and Spanish, your law firm can ensure that no client is turned away due to language constraints.
Key takeaways

• Expand your client base – bilingual support enables your firm to cater to a more diverse clientele and potentially open up new markets.
• Improves client understanding – break down language barriers, and make sure clients fully understand the legal advice and services being offered.

Manage appointments efficiently
Managing appointments can be a time-consuming task for busy lawyers. A legal phone answering service streamlines this process by scheduling, confirming, and reminding clients of their upcoming appointments. For lawyers, missed appointments can lead to inefficiencies and lost revenue. A legal phone answering service takes over the task of managing appointments, reducing the likelihood of no-shows through efficient scheduling and reminders. This not only improves your operations but also maximizes your billable hours.
Key takeaways

• Boost efficiency – simplify your scheduling process and get more time to focus on casework rather than on administrative tasks.
• Reduce no-shows – send automated reminders to decrease the likelihood of missed appointments to optimize your time.

Increase client retention
Effective communication and reliable support contribute significantly to client retention. By ensuring that client inquiries and concerns are addressed promptly, a phone answering service can help strengthen client relationships and encourage long-term loyalty.
A focus on client retention through a quality service is not only important for the client, but for your firm’s growth. In fact, it was reported that a 5% improvement in client retention could increase profitability by 25% [Forrester, 2023]. If you consistently deliver an excellent experience for your clients with the help of a dedicated phone answering service, your retention rates will improve.
Key takeaways

• Strengthen client relationships – nurture client relationships with regular and efficient communications.
• Encourage repeat business – satisfied clients are more likely to return for future legal needs.
• Generate positive feedback – happy clients often provide positive online reviews and testimonials which can attract new clients.

Customizable services
Every law firm has unique needs and client onboarding procedures and, as such, legal phone answering services focus on how best to align with these needs. From personalizing your call scripts to integrating with your existing operational tools, you can make a legal phone answering service like LEX work harder for your firm. This flexibility means that the service can evolve along with your firm, providing consistent support that is in line with your growing requirements.
Key benefits

• Scalability – as your firm grows or faces varying demands, your service can be adjusted to provide consistent and unwavering support.
• Unique client experience – build a client interaction model that aligns with your firm’s approach to client service.

We will explore the different types of charts, time frames, and how to use them effectively on TradingView.com. By the end of this chapter, you will have a solid understanding of how to use charts and time frames to analyze and trade the markets.

What are Charts and Time Frames?

Charts and time frames are the foundation of technical analysis. A chart is a graphical representation of a security's price action over a specific period. Time frames, on the other hand, refer to the duration of the data displayed on the chart. In other words, time frames determine how much data is displayed on the chart and how often the data is updated.

Types of Charts

There are several types of charts, each with its own strengths and weaknesses. The most common types of charts are:
1. Line Chart: A line chart connects the closing prices of a security over a specific period, creating a continuous line. This chart is useful for identifying trends and patterns.
2. Candlestick Chart: A candlestick chart displays the high, low, open, and close prices of a security over a specific period. Each candle represents a specific time period, and the color of the candle indicates whether the price closed higher or lower than the previous day's close.
3. Bar Chart: A bar chart is similar to a candlestick chart but does not display the open and close prices. Instead, it shows the high and low prices, as well as the open and close prices.
4. Renko Chart: A Renko chart is a type of chart that uses a unique algorithm to create a chart that is not based on time. Instead, it uses price movements to create a chart that is more focused on the price action.

Time Frames

Time frames determine the duration of the data displayed on the chart. Common time frames include:
1. 1-minute: A 1-minute chart displays the price action over a 1-minute period.
2. 5-minute: A 5-minute chart displays the price action over a 5-minute period.
3. 15-minute A 15-minute chart displays the price action over a 15-minute period.
4. 30-minute: A 30-minute chart displays the price action over a 30-minute period.
5. 1-hour: A 1-hour chart displays the price action over a 1-hour period.
6. 4-hour: A 4-hour chart displays the price action over a 4-hour period.
7. Daily: A daily chart displays the price action over a 1-day period.
8. Weekly: A weekly chart displays the price action over a 1-week period.
9. Monthly: A monthly chart displays the price action over a 1-month period.

I started picking up VIM about 2 days ago with the vimtutor command and was basically just holding down w and e plug hjkl to move around along with ^ $. Seeing how the pros move with the leaderboard function showed me how fast I could get and also what are the most recurrent keys I should know first to be fast (* and n/N were super strong) also I now can clearly see how jumping around with capital W and E makes sense a lot of the time when I don't want to get stuck on punctuation in code.
I finished the site's content in like 15 minutes and it taught me wayyy more practically than vimtutor did, really they are great together though.
If I had one suggestion it would be to add a randomize cursor position mode so I could practice endlessly without starting to memorize where the cursor prompt will jump to next.
Thanks for developing such an amazing learning tool!

Finsbury Park mosque chair Mohammed Kozbar, who is prominent on the flyer urging people to vote for the former Labour leader, called Sheikh Yassin the ‘master of the martyrs of the resistance’

Jeremy Corbyn’s attempt to regain the parliamentary seat of Islington North as an independent MP in the general election has been endorsed by a Muslim leader who has publicly praised the founder of Hamas, Sheikh Yassin.
Mohammed Kozbar, the chairman of Finsbury Park Mosque, is also deputy general secretary of the Muslim Council of Britain. His is the first name on a leaflet of Corbyn supporters urging people to vote for the former Labour Party leader. Corbyn, who has held his seat since 1983, was suspended from the Labour Party in 2020 after he declared that antisemitism in the party had been overstated.
When he formally announced that he was ready to run in the July 4 2024 general election as an independent, Labour expelled him. Corbyn has now issued a leaflet of people endorsing him — and Kozbar’s name leads the list.
Kozbar wrote: “Jeremy is full of humanity and compassion. He is a fantastic MP who cares about everyone in his community”. Previously, his description of Hamas founder Sheikh Yassin as “the master of the martyrs of the resistance” caused concern.
After his election as deputy general secretary of the Muslim Council of Britain in February 2023, the Muslim activist said: “I have demonstrated interfaith action at a local level, and it is much needed at a national level. I look forward to particularly building this with our Jewish friends, with whom we have so much in common. Antisemitism and Islamophobia must both be tackled vigorously. I have worked with many Jewish colleagues, who have looked past the Islamophobic smears that have been levelled at me in the past…”
But in February 2024, the Metropolitan Police decided to cut ties with Kozbar, who had been a member of its London Muslim Communities Forum. The police said they had decided to “cease engagement” with Kozbar “after a social media post from late January 2024 was brought to our attention and reviewed”.
It is understood that this may have referred to Kozbar’s “like” for a video post on TwitteX by the profoundly anti-Israel rapper, Lowkey, which claimed that “Israeli intelligence companies” were “taking control of key functions of our intelligence and police services”.
Kozbar had also “liked” a post by the former head of Hizb ut-Tahrir in Britain, Dr Wahid Shaida. On January 19 2024, Dr Shaida said he would “continue to speak about things I believe in”, despite Hizb ut-Tahrir being proscribed as a terror group by the British government.
In February, a Met Police spokesman told the Daily Telegraph: “Mr Kozbar is no longer an adviser to the Met. The decision was taken to cease engagement with Mr Kozbar as an adviser after a social media post from late January 2024 was brought to our attention and reviewed.
“The Met works with a range of faith and community adviser groups, locally and centrally. This vital work helps us improve our response to the crime and anti-social behaviour issues faced by all communities across London.
“We are currently reviewing how we work with our network of advisory groups to ensure that, like the Met, they are committed to building a better London that promotes mutual respect and inclusivity.”
Much of Kozbar’s TwitteX content consists of repostings of opinions with which he allegedly agrees, rather than declarations of his own.
Previously, speaking in relation to his comments about Sheikh Yassin, the founder of Hamas, Kozbar said: “I spoke on the extra-judicial assassination of a paraplegic man who was wheelchair-bound… my comments were made well before this organisation [Hamas] was proscribed.”

Many Sources

As many C++ developers are interested in performance analysis, I would like to share perf-cpp, our library dedicated to recording performance counters directly within C++ applications.
perf-cpp functions as a wrapper for the "perf_event_open" system call, allowing precise measurement and analysis from your C++ applications (and for specific code segments instead of recording the entire application).
Key Features:

• Targeted Performance Counters: Record and analyze metrics specifically tailored to particular code segments.
• Event Sampling: Detailed capture of events such as data accesses, instruction pointers, and branch records, providing deep performance insights.

We used the library already in several research-related projects and we are hoping that it can be of service to someone else as well. I value any feedback, ideas, or pull requests to further refine perf-cpp.
You can find the library and a bunch of examples on GitHub: https://github.com/jmuehlig/perf-cpp
