But there is a grain of truth to their commentary. "Modern" gets old fast, it probably shouldn't be used, just like "new" shouldn't be used in project/library names. IMHO, removing "modern, flexible a

Thanks for that reference. Do you know if the JVM still uses thin locks? Did they migrate to thin locks? I ask because I found a 9 year old reference with a JVM calling futex: https://stackoverflow.com/questions/32262

Reminds me a bit of Steve Yegge's latest [^1]. He gives an LLM full control over his editor (Emacs) by allowing it to call eval (as I understand it). He doesn't talk about which guardrails (if any) he put on this. [^1]: https:&#x

Not sure if there is already quorum on what a solution for adding labels to non-point-in-time[^1] profiles like the heap profile without leaking looks like: https://go.dev/issue/23458 . [^1]: As opposed to profile that

This goes straight into my reference list. Sandboxing a process is confusing on Linux. I appreciate that the article focuses on approaches that drop privileges without having root oneself. I've seen landlock referenced at time ( https:

This is one area where Gerrit Code Review is (was? I don't know if it changed) is superior. It stores everything it knows about in git repositories (preferences in a separate meta git repository, comments, patches). With the right refs

Does anyone know how this contrasts with `text-align: justify` (mentioned in https://news.ycombinator.com/item?id=43258709#43260606 )? In Chrome (can't test Safari), `text-wrap: pretty` has a much milder effect. Should

I have the opposite experience. I find Cortazar impenetrable, but the Borges stories "speak to me".

I should correct and clarify: I meant 3-4x more expensive in relative terms. Meaning: - For C++ programs, the allocator (allocating+freeing) consumes roughly 5% of cycles. - For Go programs, the allocator (runtime.mallocgc) used to c

It is not. Please see my answer ( https://news.ycombinator.com/item?id=43545500 ).

Side note: see https://tip.golang.org/doc/gc-guide for more on how the Go GC works and what triggers it. GC frequency is directly driven by allocation rate (in terms of bytes) and live heap size. Some examples: -

Comparing with a fairly optimized malloc at $COMPANY, the Go allocator is (both in terms of relative cycles and fraction of cycles of all Go programs) significantly more expensive than the C/C++ counterpart (3-4x IIRC). For one, it has

Upstream thinks a type-safer `sync.Pool` is a good idea too. It's being discussed in https://go.dev/issue/71076 .

I've experienced quasi-remission twice now. Both times when I got so sick from food in a foreign country that I couldn't eat for days (and had no appetite for it either). I lived on water. Afterwards, for 1-2 weeks, I did not requ

That sounds like double-buffering. Or did I misunderstand? Is it actually a ring-buffer? Can you give more details? What is a Half-Transfer interrupt?

I actually like `nvim --clean`, which is just the basics. Early on in the Neovim project, a lot of heirloom defaults were changed to be more modern, resulting in a better (IMHO) out-of-the-box experience. I use `nvim --clean` as my man-page

I highly recommend this to anyone reading HN. I wouldn't say it changed my life, but I think about Borges and Fictions/The Aleph at least once per year.

Copying makes for surprising semantics, and prevents some representation changes. An example w.r.t. the surprising semantics: var ms []mypb.Message = ppb.GetMessages() // A repeated submessage field for i, m := range ms {

It's true that this would perform better, and greatly reduce allocations. But: - Messages (especially opaque ones) are not supposed to be copied. The recommendation is to use `m := &mypb.Message{}`. - This would make migr

Can you be specific? I'm curious.

Both, actually. Without accessor methods, laziness couldn't be implemented.

You've obviously done a bit of research. Have you ever seen the vitamin B12 link referenced in other studies? Are you taking supplements or did you get it tested?

At least if one self-compiles Neovim (which I do), it's statically linked.

I'd love to use this to profile Neovim, where (nowadays) user scripts are often written in Lua 5.1. Neovim by default embeds LuaJIT (close to HEAD). Being able to see Lua functions and C functions in the stack would be amazing. Is ther

Objective-C? That seems like an odd choice, did they want to attract iOS developers? (I know someone ported the mobile game Angry Birds to PSP at some point). Do you have more information about this?
