Ruby's a great language- I've always enjoyed its ergonomics and clarity. But its editor tooling hasn't kept up with its one-time competitor, Python.I've mostly been in the Python ecosystem for the past few years and the LSP investment from Microsoft has really shown. Rich Python support in VSCode is seamless and simple. Coming back to Ruby after that caught me off guard - it feels like I'm writing

That's a good article. He's right about many things.I've been writing a metaverse client in Rust for several years now. Works with Second Life and Open Simulator servers. Here's some video.[1] It's about 45,000 lines of safe Rust. Notes: * There are very few people doing serious 3D game work in Rust. There's Veloren, and my stuff, and maybe a few others. No big, popular titles. I'd expected some A

I created a pet project (REST API) with Hono and I'm seriously considering using it for future projects instead of what has been my go-to stack for years (Express, lately with Zodios).Hono's middlewares, especially zod-openapi[1] and @scalar/hono-api-reference[2], make it really easy to define your REST endpoints once and get full typesafe routes with request/response validation, an automatic Open

Very annoying - the apparent author of the backdoor was in communication with me over several weeks trying to get xz 5.6.x added to Fedora 40 & 41 because of it's "great new features". We even worked with him to fix the valgrind issue (which it turns out now was caused by the backdoor he had added). We had to race last night to fix the problem after an inadvertent break of the embargo.He has been

It's the lists.No, not the prefix notation, parenthesis, what have you, although that doesn't help. The lists themselves. In Lisp, code is data, and data is lists. Yes, of course, there are hashmaps, arrays, strings. But idiomatic Lisp code really does use linked lists extensively, it's an entire style of programming. Even if you'd prefer to use different data structures (and again, Common Lisp do

Ah sorry - that was an unintended side-effect of re-upping the original submission. I must have done some of the steps in the wrong order. You mean you don’t have a distributed merge post microservice that emits post migration events, which are then consumed by a post owner conversion service using your existing event-driven architecture to facilitate seamless data synchronization and user notific

For better or worse, my experience as a GitHub cofounder and author of several Git books (Pro Git, etc) is that the Git commit message is a unique vector for code documentation that is highly sub-optimal.The main issue is that most of the tooling (in Git or GitHub or whatever) generally only shows the first line. So in the case of this commit example would be the very simple message of a generic "

I think it's really cool that Haoran Xu and Fredrik Kjolstad's copy-and-patch technique[0] is catching on, I remember discovering it through Xu's blog posts about his LuaJIT remake project[1][2], where he intends to apply these techniques to Lua (and I probably found those through a post here). I was just blown away by how they "recycled" all these battle-tested techniques and technologies, and us

Looks great, however note that it doesn't do tail calls, which are required on conforming implementations. I suspect it does tail calls on Safari as Safari is the ONLY browser to completely implement ES6+ and implement proper tail calls (I'd note that it's not the only ES6+ compliant implementation, but most of the rest are aimed at microcontrollers or embedding).

There are two dedicated CPU feature flags to indicate that REP STOS/MOV are fast and usable as short instruction sequence for memset/memcpy. Having to hand-roll optimized routines for each new CPU generation has been an ongoing pain for decades.And yet here we are again. Shouldn't this be part of some timing testsuite of CPU vendors by now? I'm completely making stuff up here, but I wonder if this

FWIW, I wouldn't try to parse escape sequences directly from the input bytestream -- it's easy to end up with annoying edge cases. :-/ In my experience you'll thank yourself if you can separate the logic into something like:- First step (for a UTF-8-input terminal) is interpreting the input bytestream as UTF-8 and "lexing" into a stream of Unicode Scalar Values (https://www.unicode.org/versions/Un

The real gem of Firefox is Containers. No other browser has something like this. It's something critically missing from Chrome. I don't mean "Just create a private window", I mean being able to create 1 + infinitely many profiles/containers. Firefox has an extension called Temporary Containers that makes this better: Every new tab is a temporary, ephemeral container. By default I get isolation. I

No offense to the creator of YAML, but: The fact that it became one of the de-facto standards for cloud tooling is an absolutely damning statement about the state of the industry.I get that XML is about as sexy as mainframes, and that a lot of folks here probably have PTSD from working with Java/Spring web apps, but YAML is about the worst of all worlds.

There has been a lot of interest on HN in fine-tuning open-source LLMs recently (eg. Anyscale's post at https://news.ycombinator.com/item?id=37090632). I've been playing around with fine-tuning models for a couple of years, and wanted to share some insights and practical code.

This is great, JQ is brilliant.I love JQ so much we implemented a subset of JQ in Clojure so that our users could use it to munge/filter data in our product (JVM and browser based Kafka tooling). One of the most fun coding pieces I've done, though I am a bit odd and I love writing grammars (big shoutout to Instaparse![1]). I learned through my implementation that JQ is a LISP-2[2] which surprised

I tried Nostr for awhile, and I appreciate that they're picking up where Scuttlebot left off. There are a few things that bug me about it that I wish they'd fix, or that some future protocol will solve.First, I want a replication strategy. Nostr messages get lost in time, and many of the clients end up just blasting an entire message history at your client. Because there's no clue in the protocol

For typing **kwargs there are TypedDicts https://peps.python.org/pep-0692/If your function just wraps another you can use the same type hints as the other function with functools.wraps https://docs.python.org/3/library/functools.html#functools.w...

The authors implemented a stack-based virtual machine for their benchmarks, but as they briefly alluded a register-based virtual machine should perform better. With a register-based VM there is no excessive stack fiddling and fewer instructions to perform the same task. Consider the instructions for adding two integers and storing the result in a variable. In a stack machine this requires four ins

The main reason is that they're too low-level to use directly.They do a lot, but stop just short of being useful without something of a framework on top. I tried hard to use them directly, but found that it was untenable without sensible template interpolation, and without helpers for event binding. Here's my shot at the smallest possible "framework" atop Web Components that make them workable (an

1. SummaryThe author is suggesting that we add 1 to the denominator of the softmax that is used within attention mechanisms (not the final output softmax). The softmax inside an attention unit allows it to see key/query matches as probabilities; those probabilities support a continuous-valued version of a key-value lookup (instead of 1/0 output of a lookup, we get weights where a high weight = the
