Task: "this function should work with any type that can return a &T".

Rust: let me educate you on Deref, Borrow and AsRef. But if your type is hidden behind Rc<RefCell<T>>, Arc<Mutex<T>> or Arc<RwLock<T>>, you'll need to play a 5D chess match against your compiler to make it work.

Sorry. I'm just preparing myself for that role very soon and trying to figure myself a way out between different (often contradictory) advices.

From what I've heard this is not actually a good thing. Basically a sleep-induced starvation at that age.

Have anyone tried to implement Rope data structure over persistent key-value storage?

Some thoughts back from the vacation on African dessert: current world of software expects you to be permanently online and that sucks really badly.

Even my music app and video player first hangs for a minute trying to connect before giving up and letting me work on it. This is unacceptable.

Agree on deeply disturbing 😜

Why bother to read something nobody could be bothered to write?

put another way: i don't want your data—not just from an ideological "users should be in control" perspective, but from a pragmatic "this makes my app harder and more expensive to run" perspective

we've been so focused on making it easy to scale up that we've accidentally made it hard to scale down

Yes. Thank you :)

I'm looking up for papers about on-disk trie/radix/prefix tree-based key-value stores. I've heard about Cassandra switching some time ago (cassandra.apache.org/_/blog/Apach...). Are there any other good insights into these data structures?

Idea: have a Rust bytes::Bytes<T> variant, where T describes how to interpret its binary content, ie.:

- Bytes<Utf8>
- Bytes<Lz4<T>>
- Bytes<ZerocopyStruct>

this way we also never assign incompatible data like `Bytes<Lz4<T>> => Bytes<T>`.

My main purpose for immutable data types is to use them together with compare-and-swap.

From what I've seen, a lot `im` API is internally immutable but uses `&mut self` for user-facing methods. Additionally the target structures are not register-sized, so I need extra allocs and checks.

Looking at the state of cargo crates related to immutable/persistent data structures (some having < 300 downloads, most not updated for 3+ years), I'd say that this domain pretty much died in Rust ecosystem.

My favourite part of Akira is that its portrait of the fallen, post-apocalyptic youth looks basically the same as in a regular US high-school drama from the 90's.

Well, depends heavily if you have or don't have the money. If you fund your venture out of your own pocket you better have a very good reason for spending a sum of money PER YEAR for which you can establish an entire elementary and high school in Europe including building the campus.

You can easily find stores to buy alcohol 24h/day, yet pharmacies with such availability are so rare...

New level unlocked: copilot autocomplete started adding features that don't exist in the language (in my case: adding function params with default values in Rust :) ).

It sounds like you've just became the world's most micromanaging team leader in charge of a group of irredeemable juniors. Not really an envious place to be in tbh.

Ok, so iPhone Air has bad battery, doesn't support physical SIM cards or 5G. And USB 2.0 charging port... Who is this shit made for?

Reading HN comments on "Why Local-First Apps Haven't Become Popular?" to discover that 90% of the readers don't understand what local-first (or local-only tbh) actually implies.

SIMD Within a Register: How I Doubled Hash Table Lookup Performance | MALTSEV.SPACE It started with a simple thought: four bytes in a hash table bucket look just like an integer. Luckily, this one idea led to a deep dive into bit-twiddling and a 2x performance boost.

Learned about SWAR the first time in the one-billion row challenge. Nice explanation including benchmarks.

Fuck me this is bleak.
But please, do continue to use GenAI slop thumbnails for your YouTube videos, or your album art, or your book covers or whatever else. I'll continue to refuse to watch/listen/read any of them, knowing already they're not worth the time & that you're a disappointing lazy hack.

While atm. bitchat already supports BLE, there are also plans for WiFi Direct and... low-bandwidth ultrasonic communication in case when you wanted to chat in environment where radio signal is jammed or dangerous: github.com/permissionle...

I tried to watch National Geographic movies on youtube, but with my current level of ADHD, these are barely watchable.

They're 40+min videos that hide maybe 10-15min of actual content. The rest is just repeating the same facts and building shock/suspension narrative.

As for claims of "X hours of video". What sucks up my battery the most during trips is taking photos: which automatically triggers HDR + AI "enhancements" I didn't ask for. You can turn them off, but they can go back on randomly after updates.

Why would I care if new iPhone is even thinner, when I still need to somehow sit with 6.5'' titanium rectangle in my pocket?

I understand that's better UX than Git, but fundamentally jj is missing features that I think should be part of VCS repo:
- issue tracker
- code review
- repo navigation that doesn't turn into bash hackathon

TIL that Fossil (SQLite internal version control system build on top of SQLite) has a chat feature - which supports Markdown syntax including table and diagrams rendering: fossil-scm.org/home/doc/tru...

Tbh. I wanted to move my private repos out of Github. And as I'm on that, I'd like to give some other vcs a chance - I think, I'll go with Fossil.
