I will definitely reads these books when they come out.

For a historic overview of mathematics with (accessible) formulas I highly recommend “Journey through genius: The great theorems of mathematics”.

To me it looks like simple, clear examples of potential issues. It's unfortunate to frame that as "crapping on Go", how are new Go programmers going to learn about the pitfalls if all discussion of them are seen as hostility?

Like, rightly or wrongly, Go chose pervasive mutability and shared memory, it inevitably comes with drawbacks. Pretending they don't exist doesn't make them go away.

Concurrent programming is hard and has many pitfalls; people are warned about this from the very, very start. If you then go about it without studying proper usage/common pitfalls and do not use (very) defensive coding practices (violated by all examples) then the main issue is just naivity. No programming language can really defend against that.

Your note on politics is interesting because my anecdotal experience was quite different.

I worked at an Airbus offshoot in Silicon Valley and my visit to Toulouse for a bunch of meetings with the teams working on new tech and AI things were somewhat shocking.

The amount of sniping in meetings, and the amount of post-meeting behind the back sniping was somewhat shocking.

This was somewhat mirrored to a lesser extent even in our videoconf meetings and other collaborations.

It left me wondering how a group of people who seem to think so poorly of each other and work so dysfunctionally could actually come together to build some of the most amazing machines on earth (because modern airliners truly are such things).

The best take I could come up with was "Maybe all the adversity and mistrust means the end up building things that survive intense scrutiny."

Maybe the real reason is more related to Price’s law/Pareto’s principle, loosely meaning that 90% of the work is done by 10% of the people. In other words, in large companies most perons do not contribute much, at least not at the same time.

Anyone knows what does "native" means here precisely? Steam Deck has a x86-64 instruction set AFAIK, so it's just same as a the Windows version? Or has it to do with the GPU / OS? Or does it just mean "properly configured"?

If this thinnest iphone air has 27 hours of video playback, why does the regular iphone 17, which looks twice as thick only has 30 hours? At this point, I just want long battery life. Like an "all-week" battery life would be a nice start.

If you enjoy this art-style, definitely check out the game Return to the Obra Dinn.

I think the dichotomy you see with how positive people are about ai has almost entirely to do with the kind of questions they ask.

That seems obvious, but a consequence of that is that people who are sceptical of ai (like me) only use it when they've exhausted other resources (like google). You ask very specific questions where not a lot of documentation is available and inevetably even o3 ends up being pretty useless.

Conversely there's people who love ai and use it for everything, and since the majority of the stuff they ask about is fairly simple and well documented (eg "Write me some typescript"), they rarely have a negative experience.

Well, I use it before google, since it in general summarizes webpages and removes the ads. Quite handy. It’s also very useful to check if you understand something correctly. And for programming specifically I found it really useful to help naming stuff (which tends to be hard not in the least place because it’s subjective).

+1 from another Figma engineer who happened to work on the text engine back in the day.

I think that Evan generally wrote code that was as simple as possible — there was no unnecessary complexity. In this case there indeed is some inherent, unavoidable complexity due to the math involved and the performance requirements, but otherwise I found our text rendering pipeline very understandable.

Evan actually wrote about it if you're curious to learn more: https://medium.com/@evanwallace/easy-scalable-text-rendering...

marhee · 5 months ago

It’s a clever trick. But can it render a textured text? Transparent text, gradient fills? Maybe it can, I dont know. But why not just triangulate the glyph shapes, and represent each glyph as a set of triangles. This triangulation can be done offline, making rendering very lightweight.

marhee commented on Compact representations for arrays in Lua [pdf] sol.sbc.org.br/index.php/... · Posted by u/tkhattra

I wonder, in reality, if a Lua program uses large (consecutive) arrays, its values will likely have the same type? At the very least it is a common use-case: large arrays of only strings, numbers etc. Wouldn’t it make sense to (also) optimize just for this case with a flag and a single type tag. Simple and it optimizes memory use for 98% of use cases?
