Comment Asked ChatGPT About Redis and Valkey (Score -1) 24

```html

I hadn’t really been paying much attention to Redis until I came across this post. That led me to do some digging, and I figured others might appreciate the TL;DR. I asked ChatGPT to explain both — turns out Redis (and now Valkey) is a pretty powerful tool for devs like me doing side projects or small-scale services.

What is Redis?

Redis is a blazing-fast, in-memory data store often used as a:

  • Database
  • Cache
  • Message broker
  • Streaming engine

It stores data in RAM (for speed), but it can persist data to disk as well. It supports rich data types — strings, hashes, lists, sets, sorted sets, and even bitmaps and streams. Redis is widely used to cache web sessions, build message queues, or just offload slow DB queries.

Big plusses:

  • High performance (millions of ops/sec)
  • Built-in support for replication, clustering, and pub/sub
  • Works great for real-time analytics, queues, or leaderboard-style use cases

So... What Is Valkey?

Valkey is a community-driven fork of Redis, launched after Redis Inc. changed its license in 2024.

As of March 2024, Redis switched from the open-source BSD 3-Clause license to the Redis Source Available License (RSAL) — a move that’s not truly open source under OSI standards. This raised red flags for Linux distros, cloud providers, and open-source maintainers.

In response, former Redis contributors and new supporters created Valkey, a drop-in Redis replacement that keeps everything open source under BSD. It’s now backed by the Linux Foundation and is being actively maintained.

If you’re building open-source tools, deploying to Linux, or just want to avoid future licensing surprises, Valkey is a safe bet. It works with existing Redis clients and persistence formats, so migration is basically a one-liner.

Honestly, I’m thinking about using it in some personal projects — caching, queuing, maybe even toying with some pub/sub patterns.

Nearly all the original content on reddit comes from external sites to reddit. If the super App is getting its content from these other sites then reddit will have to adapt or become irrelevant like Myspace did. With pretty good AI in the picture now this could be easily done by a well written super app.

The way to fix this is for the 3rd party app developers to design apps that are source site independent. For example Reddit is Fun (RIF) could become All is Fun (AIF). It could pull in content from Telegram, Twitter, Facebook, or whatever as well as it does Reddit now. The type of content pulled in should be fully user defined. That way if one site become too onerous the users could adjust the app settings to make that site less favorable in content selection.

Comment Inverse Magnatron (Score 1) 22

Seriously, this looks like a magneton laid out linearly with similar channels. The description sounds like it uses electromagnetic radiation (IR frequencies) to accelerate electrons. This is the reverse of how a standard magnetron operates where it use accelerating electrons to generate electromagnetic radiation (microwaves). Is there a cross magnetic field involved with this device?
