dxxvion Unifi Travel Router

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.

dxxvion Rue: Higher level than Rust, lower level than Go

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.

dxxvion Thoughts on Go vs. Rust vs. Zig

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.

dxxvion Thoughts on Go vs. Rust vs. Zig

> 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)?

dxxvion Azure hit by 15 Tbps DDoS attack using 500k IP addresses

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?

dxxvion Unofficial Microsoft Teams client for Linux

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

dxxvion Why is Zig so cool?

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.

dxxvion Kafka is Fast – I'll use Postgres

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?

dxxvion Show HN: Apache Fory Rust – 10-20x faster serialization than JSON/Protobuf

Is Google guava really needed? I would like it to be taken out.

dxxvion We saved $500k per year by rolling our own "S3"

> I've been considering it too and hesitant about it

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

dxxvion We saved $500k per year by rolling our own "S3"

I already checked with AI before putting the comment :-)

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).

dxxvion We saved $500k per year by rolling our own "S3"

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 :-)

dxxvion How I turned Zig into my favorite language to write network programs in

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

dxxvion California invests in battery energy storage, leaving rolling blackouts behind

Does it make the electricity price go down or up? It seems to me that the electricity price never goes down.

My hacker news modified with violentmonkey: https://vercel-html-example.vercel.app/hn-violentmonkeys.png

The + - buttons on the top panel change the font size of every thing except the font size of the panel.

Things are arranged to minimize the page scrolling.

The news title and number of comments are darker and a little bit bigger than other elements for an easy reading.

dxxvion Show HN: ut – Rust based CLI utilities for devs and IT

As it is a utility toolkit, I'd like to have:

- the Web & Network section expanded: the copyparty features (github.com/9001/copyparty) and curlie (github.com/rs/curlie).

- compress/decompress features with password: it doesn't need to use the best compress algorithm, gzip is good enough.

dxxvion Cancellations in async Rust

My Rust knowledge is too low to understand. However, thank you very much for the article. I hope AI will learn it and explain to me in a few years :-)

dxxvion The AI coding trap

There is this statement in the article: LLMs are lightning fast junior engineers. I don't know if that is right or wrong. To me, good LLMs are a lightning fast better version of me. That means that I can write code like some LLMs but it'll take me days to do it (if I use a language that I'm not good at, for example Rust) but with carefully crafted prompts, LLMs take maybe half an hour or less.

dxxvion Why was Apache Kafka created?

> turn to Redis Cluster Streams instead. So much simpler to manage and so much cheaper to run

I don't have any experience with Redis Cluster Streams. Could you please tell us how it is simpler to manage? IMO, installing and managing a Kafka cluster in a non Fortune 100 scale is simple enough: run 1 java command for zookeeper, run another java command for a broker (with recent version of Kafka, zookeeper is not needed anymore). The configuration files are not very simple but not very complicated either. When we have another machine, we can run another broker on it.

Redis Cluster Streams is cheaper to run because it's written in C, doesn't need a VN to run? Or because its messages are stored in RAM not SSD?

dxxvion Cerebras Code

I agree 100%.

dxxvion A Rust shaped hole

> What we need isn't Rust without the borrow checker. It's C with a borrow checker, and without all the usual footguns

I agree with the other comment. Then what you need is Rust without all the bells and whistles (pattern matching, Cow, Rc, Result, Option ...).

dxxvion Two guys hated using Comcast, so they built their own fiber ISP

This "$80 for gigabit fiber, unlimited data" is a problem for me. I want to save money, I don't need a gigabit fiber but there's no other options. If there's $30 for 300Mbps unlimited data (I'm paying $40 for optimum) option, then I'll take it.
