I have this macbook https://support.apple.com/en-us/111883
And this tv https://www.lg.com/us/tvs/lg-oled55cxpua-oled-4k-tv
I’ll be gaming on GeForce now and want to use my Macbook to stream from so I can get the games in 4K. What adapters and cables do I need game in 4k 120hz?

I have a Windows-based plex server. Client is Plex on Amazon Fire Cube TV.
Working with Godzilla Minus One, I can't get the subtitles to synch up with the vocals. File is ~60 gigs big, video and sound are great. I tried to set the subtitle offset but it doesn't seem to work. Whether I choose a negative or positive offset, the subtitles are always delayed.
fyi - I've tried a number of different sized files from 5 gigs up to 60 gigs. Same issue with the subs.

Here is the info that plex is showing:

Are these embedded subtitles within the file? How do I choose these? I normally just open the subtitles window and pick one that pops up.
I never have this issue with other movies. This is the biggest media file I have though.

Understanding Random Number Generation in Java

Generating random integers within a specific range is a common requirement in programming, particularly in scenarios where you need to simulate unpredictability or make selections based on chance. Java, being a robust and widely used programming language, provides multiple ways to achieve this, ensuring that developers have the tools they need to incorporate randomness into their applications effectively. Whether it's for game development, simulations, or even testing, being able to produce random numbers that fall within a predefined range is crucial. This necessity stems from the desire to control the randomness to some extent, ensuring that the generated numbers serve the application's specific needs while maintaining the unpredictability that randomness implies.
In Java, this functionality is facilitated through classes in the java.util package, namely Random and ThreadLocalRandom, among others. These classes offer methods to generate random integers, floats, and other data types, but with the flexibility to specify limits, thereby tailoring the randomness to fit precise requirements. Understanding how to use these classes and methods is essential for Java developers, as it not only enhances the functionality of applications but also ensures that the use of randomness is both efficient and effective. This introduction will delve into the process of generating random integers within a specific range in Java, highlighting the significance of this capability in programming.

Command	Description
nextInt(int bound)	Generates a random integer between 0 (inclusive) and the specified bound (exclusive) using the Random class.
nextInt(int origin, int bound)	Generates a random integer between the specified origin (inclusive) and the bound (exclusive) using the Random class in Java 7 and above.
ints(long streamSize, int randomNumberOrigin, int randomNumberBound)	Generates a stream of random integers within the specified range using the Random class in Java 8 and above.

Diving Deeper Into Java's Random Number Generation

Random number generation in Java is a fundamental concept that serves a multitude of applications, from simple games to complex simulations. The ability to generate random numbers within a specific range adds a level of unpredictability and realism to these applications. Java's java.util.Random class is the cornerstone of random number generation, providing methods to produce various types of random data, including integers, doubles, and booleans. However, the focus often lies on integers due to their wide use in indexing, control flow, and simulation scenarios. One of the most common tasks is generating an integer within a specific range, which involves manipulating the output of the Random class methods to fit within the desired boundaries. This manipulation not only demonstrates the flexibility of Java's random number generation capabilities but also highlights the importance of understanding mathematical operations in programming.
With the advent of Java 8, the introduction of streams added a new dimension to random number generation. The ints method of the Random class, for example, can produce a stream of random integers, allowing for efficient generation of multiple numbers within a range with minimal code. This feature is particularly useful for applications requiring a large number of random values, such as in Monte Carlo simulations or when initializing large arrays with random data. The capability to specify the size of the stream, the origin (inclusive), and the bound (exclusive) directly in the method call simplifies the code and enhances readability. Java's approach to random number generation exemplifies the language's commitment to providing robust tools for developers, catering to both the simplicity needed by beginners and the complexity required by advanced applications.

Exploring Java Random Number Generation
 Java's architecture for generating random numbers is both comprehensive and versatile, designed to cater to a broad spectrum of requirements. At its core, the mechanism revolves around the java.util.Random class, which provides a pseudo-random number generator (PRNG). PRNGs in Java are algorithms that produce a sequence of numbers that approximate the properties of random numbers. While true randomness is a physical phenomenon and hard to achieve in a deterministic system like a computer, Java's PRNGs are sufficiently random for most applications. This includes everything from casual use cases, such as generating random numbers for a game, to more critical applications, such as cryptography and simulation. It's important for developers to understand that while these numbers appear random, they are entirely deterministic if the seed value of the PRNG is known.
 Further sophistication in random number generation was introduced with Java 8, which included the Stream API. This addition allowed for the generation of large sequences of random numbers in a more functional style, making operations on random numbers more concise and readable. Java also offers the ThreadLocalRandom class for multithreaded applications, which reduces contention and improves performance over using a shared Random instance. Beyond these, SecureRandom is another class designed for cryptographic applications, providing a higher degree of randomness and security. Understanding the nuances between these classes and choosing the appropriate one for a given situation is crucial for Java developers, ensuring that the generated numbers meet the application's requirements in terms of randomness, performance, and security.
 
Common Questions on Java Random Number Generation

Understanding Array to ArrayList Conversion

Converting arrays to ArrayLists in Java is a common task that bridges the gap between fixed-size and dynamic data structures. This operation is essential in scenarios where the flexibility of ArrayList is required, allowing for elements to be added or removed dynamically. Arrays, being static in size, offer fast and efficient access to elements by index, but lack the adaptability provided by ArrayLists. The transition from arrays to ArrayLists enables developers to leverage the best of both worlds, combining the speed and simplicity of arrays with the versatility of ArrayLists.
The conversion process involves several methods and considerations to ensure data integrity and efficiency. It is important to understand the underlying mechanics of both arrays and ArrayLists in Java to perform this transformation effectively. This knowledge not only aids in the conversion but also in making informed decisions about when and why to convert an array to an ArrayList. By mastering this technique, developers can enhance their code's flexibility and functionality, catering to more complex and dynamic data handling requirements.

Command	Description
Arrays.asList()	Converts an array into a list. However, the returned list is fixed-sized and backed by the original array, meaning it cannot be structurally modified (add/remove elements).
new ArrayList(Collection c)	Creates a new ArrayList containing the elements of the specified collection, in the order they are returned by the collection's iterator.

Expanding on Array to ArrayList Conversion in Java

Converting an array to an ArrayList in Java is a fundamental operation that can significantly impact the flexibility and scalability of applications. Arrays are a basic structure with a fixed size, meaning the number of elements they can hold is determined at the time of their creation. This characteristic makes arrays efficient for accessing and storing elements when the volume of data is known and unlikely to change. However, real-world applications often require more dynamic structures that can adjust their size as needed, accommodating an unpredictable number of elements. This is where ArrayLists come into play, offering the ability to dynamically add or remove items without the need to define their size upfront.
ArrayLists are part of the Java Collections Framework and provide a more versatile approach to managing collections of objects. Unlike arrays, ArrayLists can grow and shrink at runtime, making them ideal for scenarios where the amount of data fluctuates. The process of converting an array to an ArrayList typically involves using the Arrays.asList() method followed by creating a new ArrayList instance with the resulting list. This method is straightforward but requires understanding the limitations and behaviors of the resulting list, especially regarding its fixed size when directly returned by Arrays.asList(). Properly converting an array to an ArrayList not only enhances the flexibility of data management in Java applications but also leverages the powerful features of the Java Collections Framework, such as sorting, searching, and manipulating collections more efficiently.

Insights into Array to ArrayList Conversion in Java

Transitioning from arrays to ArrayLists in Java signifies a move towards more dynamic data handling within applications. Arrays, while fundamental to Java programming, offer limited flexibility due to their fixed size. This characteristic makes them less suitable for scenarios where the volume of data is not known in advance or can change dynamically during execution. On the other hand, ArrayLists provide a versatile alternative, capable of adjusting their size automatically to accommodate additional elements. This feature makes ArrayLists an indispensable tool for developers dealing with variable-sized collections of elements.
Moreover, the process of converting an array to an ArrayList involves considerations around performance and data manipulation. For instance, the initial conversion using Arrays.asList() yields a fixed-size list backed by the original array, limiting operations to those not altering the list's size. Therefore, developers often opt for creating a new ArrayList instance from this list to gain full flexibility. Understanding these nuances is crucial for effectively utilizing ArrayLists in Java, enabling developers to write more efficient and adaptable code. The conversion not only highlights the differences between arrays and ArrayLists but also underscores the importance of choosing the right data structure for the task at hand.

Client-Side Code

The following code provides the structure and logic for the client-side chatroom interface. This includes HTML, CSS, and JavaScript for handling user interactions and WebRTC functionalities.
**chat.ejs**:

        
 
 Start Streaming 
 
  
 
 
     

Limitations

1. **Number of Broadcasters**: Currently, the system limits the number of broadcasters per room to 12.
2. **Scalability**: As the number of users increases, performance might degrade due to the limitations of peer-to-peer connections.

Future Improvements

1. **Media Server Integration**: Consider integrating a media server to handle a larger number of connections and streams.
2. **Authentication and Authorization**: Implement user authentication to secure rooms and streams.
3. **Enhanced UI/UX**: Improve the user interface for better usability and visual appeal.

This comprehensive guide should help you set up and understand the many-to-many WebRTC chatroom application. Feel free to extend and modify the project to suit your needs.

Good Morning/Afternoon/Evening
I am CPC_Alice
Had a nice break?
U-Uh.... I was sick for a while and there was a lot of Mod work to be done and there was those situations that needed to be handled....
Yeah... just go on.
^T-Thanks
-------------------------------------------------------
So I was going back to my room after making some tea with honey. I sat down and I thought 'Hmn.... I better check on what's going on the sub before I go to sleep'. I was checking on some tools then I realized something.
'Hey, Alice, where is the weekly recap.'
My brain experienced a mini meltdown as I look at my current local time (its 5:59AM at the time of writing this part) and I realized.
I forgot.
FML.
It'll be less links (it takes a lot of time to actually do it) so I'll just get on with it ok? I swear that I'm usually a lot better with scheduling things on my activities! I SWEAR!
So. Doki's Wrestletuber 2024 happen. Day 1 is here. Day 2 is here. You must be living under a rock if you didn't know about it.... or is just not really up-to-date on the sub. People's minds were melting. Nijisisters/NDF too. A lot of their rrats on how Doki is isolated from her ex-Niji coworkers went up in smoke. It was good times all around.
Some people need to chill tho. Seriously. Don't harass anyone over silly things.
Hololive Q4 dropped. What does it have to do with Niji? Well, Hololive basically went "whatever Niji is doing with releasing wave after wave of new livers? Don't do that." When your near-peer competitor looks at what you're doing and they go "Nope, gonna do the opposite", alarm bells should be ringing out hard and shrill-like.
Doki is happy. Nice
So for those who don't know, Gura has decided to be more active in streaming things. Good for her. On that note, people have jokingly correlated her active state on how Hololive/Yagoo/Self-determined decided to release the "Tactical Shark" in response to Niji activity. On numbers alone, Gawr Gura absolutely mogs on a lot of NijiEN's activities single-handedly. Here is another example on how just a waiting room already has a lot more viewers than some active streams.
Not Niji related, but nice to hear stories breaks the unrelenting bad news. A FlaVR vtuber apparently got their 3D Concert. Good for them! It is actually quite inspiring to see a Vtuber that started as a meme from another Vtuber do this.
Hex Haywire is being weird. Like wtf dude. I also know he did more weird things. He also got suspended from Youtube. Links are going to be put later. Here is his stream being taken down. He did get suspended. Youtube confirming it.
More numbers. This time it is from the new Niji wave having less viewers than another Vtuber who debuted a day after him. Negligible huh...
Nijisanji EN retweets the call to ACCELERATE another wave of Vtubers. Like... one has to question as to what kind of people are actually going to audition anymore. One has to boggle to the kind of people who will unironically audition for it.
Vivi Brightshield... What an unfortunate soul. There is even a rrat of a stealth suspension over her "break".
"... but I missed my friend." was just such a statement that it makes people emotional. Be happy for them. Future Alice here: Here is a clipper of this? Maybe? I didn't watch, sorry.
Sayu had a new costume. Damn cute honestly.... A Donkey-Cat hybrid tho...?
People discovered that Sayu was involved with MiHoYo on Genshin Impact. I mean.... I knew about it when I gone down the crusade to figure out just who the main players are in the overall situation with AnyColoNijisanji. Yes, pre-Niji, she was involved.
If you don't know the context for this clip, watch WrestleTuber. He's getting the belt :P
More XTwitter mutual follows. NijiSisteNDF rrats in shambles.
Some funny memes. Added because of the amount of upvotes tbh. Made me chuckle.
Hololive flexes their 3D for their talents. One has to really wonder over things at this point.
100K Followers on Twitch for Michi. Good for her!
Here is someone making a small blurb as a retrospective on WrestleTuber and the state of things in relation with Niji/AnyColor.
More Numbers. This time it's Pippa's expired ramen cooking stream. Personal thoughts: Holy shit girl, why expired ramen like that? It tastes like soap? NO SH-T, YOU DIDN'T WASH THE SOAP OFF!. Missed the egg. I cook ok? I screamed.
Ah yes.... Raziel Warmonic has received a formal Cease and Desist Order from Nijisanji/AnyColor. Streisand Effect at full showing here. Did Nijisanji/AnyColor really think that doing this would make it better? I boggle at the mistepps that they KEEP ON DOING to themselves. Of course, the internet exploded. You want details? I WANT TO SLEEP DANG IT. Go look for it yourself. Youtube would do it.
Oh yeah. Nijisanji partnered with the NBA and attached their Vtubers to NBA teams. Hololive went with baseball and the Dodgers. AnyColoNijisanji and NBA (basketball) made a lot of people scratch their heads in confusion. Atleast Hololive/Cover with the Dodges (baseball) makes more sense because as a JP company, Baseball is very big in Japan. Honestly, it still makes me scratch my head.
So some people translated the JP talk on YahooJP Finance Message Board for the AnyColor stock. It was about the C&D.
Another numbers post. This time an analysis/meme on what kind of numbers and support you'll get if you join into Nijisanji. Why did I mention meme? Because I feel that having "support" in Nijisanji/AnyColor is an absolutely hilarious joke.
So Nijisanji looked over at Hololive. Saw FuwaMoco (rrat: they passed on taking on the pair of traveler guides) and the success they have. Decided and said "I want some of that". Hilarious memes ensued. Could they be any more transparent on their intentions? Also, apparently they are willing to take on minors for it. What the absolute f-ck. Future Alice: Apparently /vt/ has a time traveler. What the...
Some Venting from a Liver. Not much personal thoughts on it.
OffKai Maid Cafe with Robo Walk-arounds with Vtubers powered by V-Shojo. Must have been nice.
Horny on Main meme over Doki and Mint. It is about WrestleTuber.
For those who didn't know Bonnivier Pranaja, ex-NijiID, became 10Jin. Can't remember if it was mentioned before. Now you know.
A heartwarming art/meme. Feels good.
Remember that Nijisanji EN concert over at Anime Expo? You don't? I legitimately don't have it at the forefront in my head. But apparently, they still hadn't sold out the concert yet. Grim.
Doki x Youtooz figurine. I don't collect those things so I have no personal thoughts on it.
Calliope Mori is a musical guest over at Anime Expo. Holo and Niji is at the same con with music on the table. Considering the state of Niji's concert, one has thoughts.
More Numbers. MORE NUMBERS. It is a stream about the Dodges collab with Hololive.
Numbers of another kind. Doki is creeping up to her old sub numbers as Selen.
MORE NUMBERS. This time Vstats. Has pretty graphs too. At this point, is anyone really surprised? Negligible indeed.
Remember 10Jin? Yeah, The debut happen.
Matara and Mint at OffKai. Seems like they had an appropriate venue that it doesn't look depressing. Remember a certain other event...?
LIKE MORE AND MORE NUMBERS. I'm getting tired lol.
More Numbers with Graphs! This time its from some kind of Off-collab with Luxiem. Highlight is the "Negligible" amount of superchat income.
Ah yes, the OffKai + Phase Situation. I had to personally intervene on this. Still a Rrat so take it with a grain of salt. Then I had to be a bit more STERNER on a certain post. Ugh.
A meme about the AnyColor Q4 report. A generally accepted prediction is a BLOODBATH. Unless they outright lie or cook the books.
Nachoneko-mama showing off her work for Gura. Sometimes you really gotta just have something to smile about y'know?
A meme about a potential "Gura-Killer" going against Goobs and Mother Nature herself. Oh, there is no respawn mechanic btw.
10Jin and Michi Collab. Not much for me to say. Nice.
Nijisisters/NDF in SHAMBLES. Another rrat drowned like... -stops the "joke"-
The fans that Nijisanji threw away. Damn, it must sting to see them support your competition. LOL.
Nijisanji made an announcement. The schizos over at 4chan (which includes Nijisisters/NDF at this point) took it and made rrats without reading the Japanese for a massive hit of copium. Idiots.
Got a signature from Sayu on a card. Nice for OP! Time to frame that thing.
Handholding?! BETWEEN TALENTS?! WHAT?! /jk
ShyLily handling things a lot better than Nijisanji/AnyColor could. When a single person could do better than a whole corpo...
Need more rrat drownings? Here, have some more. This NijisisteNDF rrat is double dead.
Here is a reminder to not harass anyone.
Confusion and things with the Niji/AnyColorxNBA collab and some stuff on the YahooJP Financial Message Boards.
Clip on about a Mint and Sayu interaction. Didn't watch.. I want to sleep already...
Huh? A Clip of a now deleted stream. Possible rrat (considering it could be taken out of context).
... And that is it. Its... *squints* 8:11AM.
.... I'll just go to sleep.
Sorry for any spelling mistakes or things, I'm out of energy now. Yes, this is how long it typically takes.
No, I wasn't able to just "not link". I felt bad if I didn't.
Thank you everyone for reading this far!
Yours,
CPC_Alice
PS. I forgot my mobile game... I have to do the dailies *sob*

I'm new to opera, having just discovered it this year through the Met in HD streams at the cinema and I love it! I am planning a road trip to Santa Fe this summer and want some opinions on which operas would be best to see.
This summer, Santa Fe Opera House is offering: La Traviata Din Giovanni Der Rosenkavalier The Righteous The Elixir of Love

1. I find I really enjoy beautiful dramatic operas with beautiful sets and costumes. My favorites from this year's Met lineup are Florencia en las Amazonas, Madama Butterfly, Nabucco, and Malcolm X. I found Romeo et Juliette to be somewhat boring
   
2. Do operas offer English translation in some way? I saw Malcolm X and Florencia projected the verses on the set, and I love that the HD streams include subtitles. I think if people knew this, opera would reach a wider audience. How do live operas manage this?
   
3. I might go by myself, but I might bring an opera-skeptical friend. What operas in the Santa Fe lineup would be newbie-friendly?
   

Thanks for your advice!
