> the free tier will initially provide 50GB of monthly data Is it per machine or profile or ip address or something else? I switch from Firefox to Brave a few months ago because the markdown in aistudio.google.com is not displayed correctly in Firefox. I wonder if anybody has the same issue or that issue can be fixed.

No need of colored functions because that Java green thread returns a Future not Value like colored functions

Not sure if there's anybody like me. I use AI for only 2 purposes: to replace Google Search to learn something and to generate images. I wonder where there are not many models that do only 1 thing and do it well. For example, there's this one https://huggingface.co/Fortytwo-Network/Strand-Rust-Coder-14... for Rust coding. I haven't used it yet, so don't know how it's compared to the free models that Kilo Code provides.

I agree. IMO, Scala can be written in Li Haoyi's way and it's a pleasure to work with. However, the FP and Effect Scala people are too loud and too smart that if I write Scala in Li Haoyi's way, I feel like I'm too stupid. I like Rust because of no GC, no VM and memory safe. If Rust has features that a Joe java programmer like me can't understand, I guess it'll be like Scala.

I wonder how big 1300, 1400, ..., 2200 Elo chess engines are.

You can search for "travel router" on youtube, buy a router like in the videos and done. However, a lot of cruise ships forbid travel routers, so you might need to buy a router which you can take the antenna out (keep the router in one luggage, the antenna in another luggage :-) ). I never did that though.

Not sure if anybody gives you the answer to "what is tailscale?". So, this is my answer (hopefully it's correct and simple enough to understand).

Tailscale allows devices that can access the Internet (no matter how they access the Internet) to see each other.

To do that, you create a tailscale network for yourself, then connect your devices to that network, then your devices can see each other. Other devices that are connecting to the Internet but not to our tailscale network won't see your devices.

AI might explain it better :-) Don't know why I wanted to explain it.

You couldn't get the rue-lang.org domain? There are rust-lang.org, scala-lang.org, so rue-lang.org sounds better than .dev.

I'd love to see how Rue solves/avoids the problems that Rust's borrow checker tries to solves. You should put it on the 1st page, I think.

I wonder what the advantage of passing it around is when it makes the argument list longer. The only advantage that I can see is that it emphasizes that this function does something with cache.

> It's exceedingly rare to see any sort of global mutable state I know a bit of Rust, so you don't need to explain in details. How to use a local cache or db connection pool in Rust (both of them, IMO, are the right use case of global mutable state)?

I wonder why nowhere talked about who Jia Tan was. In my understanding, a few people already talked to that person. Now, does Jia Tan really vanish?

I agree. Screen sharing in Teams used to work in Firefox but not in the current version (144). It works in Chrome though.

New comment by dxxvi in "Why is Zig so cool?"

dxxvi — Sat, 08 Nov 2025 01:52:52 +0000

There's at least 1 thing that Zig is better than Rust is that Zig compiler for Windows can be downloaded, unzipped then used without admin right. Rust needs msvc, which cannot be installed without admin right. It is said that Rust on Windows can use cygwin but I cannot make it work even with AI help.

Is it true that a message from a queue will disappear after it is consumed successfully? If yes, at this moment, how do you make kafka topics work as queues?

Why hesitant? Just ask AI. It'll tell you how to do it and then you can experiment it yourself.

1GB with the bytea data type (https://www.postgresql.org/docs/current/datatype-binary.html) and 4TB with the BLOB data type (https://wiki.postgresql.org/wiki/BinaryFilesInDB).

So, you want a place to store many files in a short period of time and when there's a new file, somebody must be notified?

Have you ever thought of using a postgresql db (also on aws) to store those files and use CDC to publish messages about those files to a kafka topic? In your original way, we need 3 aws services: s3, lambda and sqs. With this way, we need 2: postgresql and kafka. I'm not sure how well this method works though :-)

Do you know that there's a concurrent Scala library named ZIO (https://zio.dev)? :-)
