Who is in space? Well, Tim Curry of course!

Doesn't fingerprint mean that someone could knock you unconscious and unlock it with your finger? I don't know if I'd install my bank apps here.

I was actually looking forward to a smaller iPhone. To have less addictive screen time. It looks like the Air was a once-thing. I don't see them releasing an e-ink phone either.

Maybe the answer lies in only wearing an Ultra watch if it becomes powerful enough and can function independently of a phone.

sqquima··on The August 17 outage
This is one of the scenarios where I feel we as engineers should have been more diligent in publicly writing down what techniques have worked in which scenarios and what haven't, and the AI could have gathered decades of operational knowledge and provide proper guidance to architects designing new systems. It's also true that we're witnessing unprecedented levels of scale.

Maybe the retry logic was vibecoded instead of using an existing hardened library. After all, according to Twitter, nobody is looking at the code anymore.

Meta commentary but it felt fresh to read a long wall of text that didn't seem to be AI generated. Thanks.

Are there modular databases with clearly differentiated components? I wouldn't be surprised if there aren't, as the trade-off with modularity is usually performance.

Direct access to the database, and create the "refund program" on the fly. Yes, stuff of nightmares.
sqquima··on Ask HN: Are most corporate SWE jobs performative?
I don't think it's either black or white. That said, I wanted to highlight that some adults do have some neurodivergence, which, in a way, makes them a bit naive and unable to navigate the game you mention. There is no need to be condescending.
sqquima··on Ask HN: Are most corporate SWE jobs performative?
These companies do some marvelous engineering work, but it seems that the engineering skills get you in, while the political skills get you through performance reviews. There should be a FAANG-like acronym that encompasses great companies that aren't toxic.

Yes, this looks similar to wslc announced at Microsoft Build. They should have joined forces, Apple and Microsoft. Can you imagine?

sqquima··on What color is your function? (2015)
I do find it annoying. Let's say in JS I have `result = list.map(f)` but now `f` returns a Promise.

`result = await Promise.all(list.map(f))` is less pleasant to read. And before writing it, I have to think if I want the `f` function to execute concurrently across all entries of the list, or one at a time: `for (const elem of list) { await f2(elem) }`.

Or maybe I should use a library like `p-map` and carefully set the concurrency level. Or maybe I should create a bulk version of `f` that takes an array and is more efficient than calling `f` N times.

And don't get me started when there's `list.forEach(f)` and `f` becomes async, so now it executes concurrently for all elements, and the engineer who made the change didn't realize it.

And then there's Async Generators ...

sqquima··on Rewrite Bun in Rust has been merged
My read. If the code has a comprehensive feature test suite, a performance test suite (how long a function takes), and a linter with readability guidelines (e.g. cyclomatic complexity; no code duplication), and the LLM rewrite passes all three, then it should be fine. But I think that in the real world only the first one (functional tests) exists.
sqquima··on Ask HN: We just had an actual UUID v4 collision...
Meta, but if I had a question like this, I'd likely have asked on Twitter or Reddit first. I'll keep in mind using HN as an alternative Q&A site.

Location: SF Bay Area. Can do Remote/Hybrid/Onsite

Willing to relocate within the USA: yes, depending on the opportunity. I require E-3 visa sponsorship as I was recently part of a mass layoff.

Willing to relocate elsewhere: depending on the opportunity and if relocation costs are covered.

sqquima··on What async promised and what it delivered
I'm curious how escape analysis works with virtual threads. With the asynchronous model, an object local to a function will be migrated to the old generation heap while the external call gets executed. With virtual threads I imagine the object remains in the virtual thread "stack", therefore reducing pressure in garbage collection.

It would be interesting if it allowed to use the cache as ram and could boot without any sticks on the motherboard.

Very similar config, but I bought a second pair of ram. Running 4 sticks at 3600. Also, the LAN port of the motherboard stopped working after a week, so I had to buy an Ethernet card
