tl··on Squeak 6.1
Ignore the syntax for a moment. Minus Javascript, HTML + CSS is a green screen terminal with better fonts and image support. Message passing (fetch, XMLHttpRequest, polling, streaming, etc...) is how you build something that feels like a real tool out a system where the sandbox gets in the way of everything you want to hold locally.
tl··on Apple Silicon Exec Explains Mac Mini AI Demand and On-Device Future
You'd be surprised. This was the same conversation where Numbers was pitched as an Excel replacement.
tl··on Apple Silicon Exec Explains Mac Mini AI Demand and On-Device Future
I asked an Apple (via a sales rep who visited our company to showcase in internal iPad healthcare app) to please do this for iCloud when iCloud Drive was in-development. We would have easily paid $50,000 for a rack-able Mac Pro you could point "managed" devices at.

Apple simply cannot comprehend the ask.

tl··on Show HN: Fast, native Mac file manager (filters, fuzzy find, 9 MB, no Electron)
It's not a widespread issue but it's hardly new. DiskTop was an add-in that's almost as old as the Mac itself, and PathFinder has had a business model for most of the life of OSX.

Alternative file managers are arguably a healthy property; the alternative is the phone where you cannot compete meaningfully with the Files app. And Finder works for most basic needs, something which is not true of its mobile counterpart.

tl··on Valve open-source the Steam Machine e-ink screen so you can make your own
It does not. Source: have a dock. Latest firmware installed from deck. And because the current Steam controller is a recent release, I had to try a whole mess of third party controllers before settling on PS5 controllers because everything else I tried had Bluetooth pairing issues / disconnects as you approached four controllers.

SteamDeck as a handheld is great plus or minus a few nits baked onto the power / battery life choices Valve made. SteamDeck -> TV and SteamDeck -> USB-C KVM are both workable, with caveats. I had hoped we would see the bug fixes you describe before the Steam Machine release. Alas, no.

tl··on Valve open-source the Steam Machine e-ink screen so you can make your own
I like the SteamDeck I have, but it doesn't do HDMI-CEC or controller wake from sleep today. Valve needs to prove the Steam Machine doesn't fail here.
tl··on ZCode – Harness for GLM-5.2
Simple example: a while back LLMs would trip over questions like "how many Rs are in strawberry". Now, the system prompts have a line like "when a user asks for a count, actually count the value by calling a tool if needed". The LLMs cannot get smarter in this regard, next token predictors will hallucinate here.

A harness is that covering every blind spot or sub-optimal but probable output people have hit in the wild, and a lot of problems just have better solutions if you say "break problem A into subproblem B and subproblem C, then solve".

tl··on Zig: Build System Reworked
The OG of these is probably C and Assembly. C and (Emacs) Lisp is well known. Arguably, it's the entire reason we have Python. But if you want to pair Zig against something, I would look at Lua.
tl··on Spain to expand internet blocks to tennis, golf, movies broadcasting times
This is America. We gerrymander the vote and blame the victim. Sorry you got downvoted.
tl··on I run multiple $10K MRR companies on a $20/month tech stack
https://antonz.org/sqlite-is-not-a-toy-database/ — 240K inserts per second on a single machine in 2021. The problem you describe is real, but the TPS ceiling is wrong by three orders of magnitude on modern hardware.
tl··on Gemini 3 Deep Think
Per BalatroBench, gemini-3-pro-preview makes it to round (not ante) 19.3 ± 6.8 on the lowest difficulty on the deck aimed at new players. Round 24 is ante 8's final round. Per BalatroBench, this includes giving the LLM a strategy guide, which first-time players do not have. Gemini isn't even emitting legal moves 100% of the time.
tl··on Retiring GPT-4o, GPT-4.1, GPT-4.1 mini, and OpenAI o4-mini in ChatGPT
I have Claude whiplash right now. Anthropic bumped limits over the holidays to drive more usage. Which combined with Opus's higher token usage and weird oddities in usage reporting / capping (see sibling comments), makes me suspect they want to drive people from Pro -> Max without admitting it.
tl··on Things I've learned in my 10 years as an engineering manager
Most of the job is noticing friction and clearing paths — which requires context and trust more than technical superiority.

In practice: Start a note for each engineer you manage. Fred Brooks called this a "career file". Start by writing down things that frustrate them enough to complain about publicly. Add hurdles that come up in their one-on-one. Identify problems you can solve, problems you understand but cannot solve right now and problems you do not understand.

Then put on your PM hat; sort by priority and execute.

tl··on Inside CECOT – 60 Minutes [video]
I recommend everyone bookmark the archive.org link or download via the magnet link since HN is disappearing these.

Also, any recommendations for a news site that doesn't suppress news? Asking for a friend.

tl··on How we built the v0 iOS app
Balatro and a number of other games have. But react-native? I can't think of an example and the framework wouldn't be my choice for "award winning" design.

Watch Duty won with a Cordova app in the "Social Impact" category, so it's not impossible.

tl··on I’m worried that they put co-pilot in Excel
> If you have a good audit process then errors get detected even if AI helped introduce them. If you aren't doing a good audit then I suspect nobody cares whether your financial statement is correct (anyone who did would insist on an audit).

Volume matters. The single largest problem I run into: AI can generate slop faster than anyone can evaluate it.

tl··on Molluscs of the Multiverse: molluscan diversity in Magic: The Gathering
Foundations just reprinted Savannah Lions (the 2/1 for W). It's still a good card in Limited (one of two actual good, popular formats in MtG). The interaction soup people of thousands of cards? Actually good in commander (the other actually liked format, a causal game for four people).

MtG's primary problems are: Wizards trying to make formats happen, often making them worse in the process, and price creep on their printed cardboard from: UB price hikes and MH price hikes, rarelands, chase mythics, questionable rotation changes, Secret Lair fails, pro-scalper behavior, etc...

tl··on Making reliable distributed systems in the presence of software errors (2003) [pdf]
> The sad fact is that the software industry as a whole relies heavily on mainstream languages, and not on educating your engineers to leverage the strengths of your specialty language.

Except when the language is the workhorse of a proprietary product sold to your employer. SQL is the example that escaped into the open world, but see also MATLAB and Excel formulae/VBA.

tl··on Writing is thinking
As a similar but distinct theory, you might find Larry McEnerney‘s work interesting. Writing has two classes: a writing for thought and a writing for communication. Larry uses horizontal and vertical spatial metaphors here. Writing for thought still pre-dates cheap paper (and Socrates), but is mostly a private act. Writing for communication is a broad enough brush to span fiction and journalism. For his part, Larry teaches classes aimed at thesis writers who struggle to bridge the divide of using writing to think about a problem to conveying their answer in a paper.
tl··on Why Elixir? Common misconceptions
While Elixir is my current favorite language to hack in, it is very alien and downright hostile to integrating with existing systems. For example, relational database support was postgres focused for a long time (to the exclusion even of SQLite and continued inability to talk to Oracle). Then you have articles like https://dashbit.co/blog/you-may-not-need-redis-with-elixir pushing ETS over Redis. While it's a valid argument, it's not adoption-friendly.

Clojure brings about half the novelty of Elixir, runs on the JVM and still struggles to replace Java.

tl··on My Mac contacted 63 different Apple owned domains in an hour, while not is use
Apple has been the new Microsoft long enough, I've begun to suspect the current environment cannot support a new Apple. Joel Spoksky's 2004 "How Microsoft Lost the API War" [1] applies to Apple's 2019 introduction of SwiftUI. Some of the AI companies are trying, but the more favorably I think of a competitor in that market, the less likely they are to build consumer hardware.

tl··on Apple introduces a universal design across platforms
Maybe for "Apple", but there's one team that takes performance seriously. The WebKit team has a zero tolerance policy for performance regressions (https://webkit.org/performance/) dating back to the implementation of the Page Load Test in 2002 (Creative Selection, p. 93).

WebKit sounds like the kind of scrappy startup Apple might want to acquire and gain some hard-earned engineering knowledge.

tl··on IRS Direct File on GitHub
Which means your cries for privacy only apply for rich people and you're okay with that because you have some money.
tl··on Problems with Go channels (2016)
This is optics versus reality. Its goal was to address shortcomings in C++ and Java. It has replaced neither at Google and its own creators were surprised it competed with python, mostly on the value of having an easier build and deploy process.
tl··on Doge Claimed It Saved $8B in One Contract. It Was $8M
I just refreshed HN. This story is #10 when I'm logged in and gone when viewing from a private window.
tl··on SQLook – A free online SQLite database manager with a Windows 2000 interface
It's a biased viewpoint, but it's not nostalgia. The following all happened to me:

- 486 Packard Bell that I upgraded ram from 4MB -> 12MB as a kid? Win 3.1 went from being slow period to Windows 95 being fast any time I didn't touch disk or CD-ROM.

- ZSNES on Pentium MMX? Zero lag gameplay with time-travel debugging and full memory view.

- DOS running on a Pentium 4 to support legacy software? Nearly instant everything, especially power on -> usable machine.

You'll notice a common thread. It was possible to outrun the demons of sluggishness back then.

tl··on Steam games will need to disclose kernel-level anti-cheat on store pages
The only real answer for this is self-imposed handicaps.

tl··on macOS Sequoia is available today
> I respect that Apple has every right to completely destroy the legacy of the Macintosh

I disagree. Apple's various machinations to control the best available supply lines (deals with TSMC, etc...) make me feel quite entitled in saying what is and is not acceptable behavior on their part. This feeling amplifies with every "courageous" announcement they make sunsetting some useful feature they no longer feel like supporting.
