ch_sm··on Britain’s output per person is now only just above that of Mississippi
So to summarise: diversity, forced on the UK by some weird world order, is the reason for Britain’s economic decline. World-class analysis. Got it. Thanks.
ch_sm··on Making Graphics Like it's 1993
I don’t know. Em-dashes are normal punctuation. The prose on the site doesn‘t strike me as particularly AI-y, but of course I might be wrong. Generally speaking, if the person wants to not use AI and tell people that, thats fine by me too.
ch_sm··on The Apple Ad That Broke Microsoft [video]
It was a good ad. But also, Mac OS X at the time was so vastly and obviously ahead of Windows, it was a very natural choice if your circumstances allowed it (IMHO etc). It really really didn‘t break Microsoft. They were, and are still, more than fine.
ch_sm··on Gemma 4 12B: A unified, encoder-free multimodal model
can‘t speak to compatibility with this new model, but oMLX supports MTP drafters very well.
ch_sm··on Why Espresso Tastes Different Every Minute: Science Explains Coffee Physics
The article is quite superficial. Yes, too coarse means weak or sour, and too fine means heavy and bitter - most espresso lovers know this. Where are the x-rays, CTs and details?
ch_sm··on US inflation jumps to 3.8% as energy costs surge from Iran war
> You cannot just switch an entire country's energy source on a finger snap

no one is suggesting that

> nor do we have a viable alternative for making nitrogen based fertilizer

nor is anyone suggesting that

ch_sm··on Vladimir Putin is losing his grip on Russia
Isn‘t Iran a good counter-example? Heavily sanctioned, huge uprisings.
ch_sm··on Accelerating Gemma 4: faster inference with multi-token prediction drafters
gemma4 has a specific problem with toolcalls that affects most runtimes. fixes for ollama and vllm are being worked on right now
ch_sm··on Show HN: Access OPFS from multiple tabs using a fake Shared Worker
Hi all!

I wanted to share a library I wrote that I think is needed to make OPFS actually useful.

For context, OPFS is the Origin Private File System, giving your app a orgin-scoped high performance file system, ideal for stuff like sqlite or data intensive local-first apps.

However, if you have multiple windows or tabs, using the same FileHandle will break your app, since there can only be one FileHandle per file.

This library attempts to fix this by doing some MessagePort acrobatics between tabs, and keeps only one worker alive managing access to the file system.

It’s informed by this discussion on wa-sqlite: https://github.com/rhashimoto/wa-sqlite/discussions/81

Hope somebody will find this useful!

ch_sm··on JavaScript Is Enough
hey! Great job on this, dashersw. I‘ve believed for a while now that the compile time dependency analyzer approach is the only good way for frameworks like this. Really neat choices on the API surface as well – so simple! Launching with a headless UI lib is smart. will try both in a side project soon! thanks and cheers!
ch_sm··on Anthropic raises $30B in Series G funding at $380B post-money valuation
> Safari is still working on pulling theirs back up.

not sure about this take, given that chrome‘s rendering engine was famously based on Safari‘s - WebKit - before they forked it (Blink). V8 was indeed faster than Safari‘s JS engine at the time. However, today, Safari is objectively faster in both rendering (WK) and JS performance (JSCore).

ch_sm··on Ensuring a National Policy Framework for Artificial Intelligence
I see your point, but that is definitely not the only cause of American economic dominance. The U.S. has been the largest economy by GDP since ca 1900 – i.e. before the wars.
ch_sm··on Koralm Railway
Really? I always thought it was London in 1801. Do you have a link to the data?
ch_sm··on BMW PHEV: Safety fuse replacement is extremely expensive
> Huh? Every EV uses recuperative braking, how is this special to Tesla?

It‘s not. But there are some newer EVs (e.g. Mercedes and VW) that track brake usage and will periodically switch to using the disk brakes when there‘s danger of corrosion.

Hi! I’m a Senior Software Engineer and project manager with over 16 years experience in the industry. Full Stack, with a strong focus on the front end side of things.

I’ve co-founded and led a music and messaging focused start up as the CTO for 5 years — from the first MVP until it got acquired in 2019.

I’m very much a product builder with a keen eye for detail and UX, a strong sense of responsibility and ownership. As a team leader I consider myself empathetic and pragmatic.

ch_sm··on Apple will phase out Rosetta 2 in macOS 28
just as a little side note: while it really isn‘t regarded as a typical mac game nowadays, Halo was originally planned as a Mac-exclusive, before Microsoft bought Bungie. If memory servese me right, Jobs even presented it as an exclusive at some MacWorld or Expo.
ch_sm··on Porsche demonstrates inductive EV charging at IAA
their site says it’s 90% efficient [0], which is impressive, but I agree, still sub-optimal for large scale installations.

The other thing is that it needs to be perfectly aligned. If you can’t be bothered to plug in a cable, can you be bothered to align your SUV in your garage perfectly with a charge pad?

ch_sm··on Ask HN: Why hasn't x86 caught up with Apple M series?
Yeah I had that same i9 16 inch from 2019. Easily the worst Mac I‘ve ever owned (in 20 years!). Now I‘m on an M2 16 inch an it is night and day.
ch_sm··on Will Smith's concert crowds are real, but AI is blurring the lines
apparently the sharpening algorithm is only applied on youtube shorts, not on regular youtube videos.
ch_sm··on About that A18 Pro MacBook rumor
Also, it doesn‘t run on iPads because it would be very difficult to use all these mouse and keyboard centric UIs with only your finger.
ch_sm··on The time is right for a DOM templating API
Agree that react isn’t the best implementation of the concept, both in terms of ergonomics and efficiency. But a react-like framework is still very much needed to create complex apps in the browser. So IMHO react is a solution to a very current problem, only not an ideal one.
ch_sm··on The No Space for Bezos movement: 'One man rents a city for three days? '
Interesting data point! But don‘t you think Barcelona is capable of making money outside of tourism?
ch_sm··on The No Space for Bezos movement: 'One man rents a city for three days? '
hm. I can see that being true for venice, but what about barcelona and paris?
ch_sm··on Apple's Liquid Glass in the Browser
This is very clever! I’d been wondering about ways to replicate the effect on the web, and this is a neat way of doing it — great job!

Aside from that, this being the first time I’m seeing the effect live, I don’t care too much for it. I wonder whether it will get very popular.

ch_sm··on Apple introduces a universal design across platforms
Haha, nice screenshot. It even has Bryce 5 in the start menu!
ch_sm··on Apple introduces a universal design across platforms
Oh cool, I had forgotten about this project, thanks for posting it! This is the first time I’ve noticed that they had the perspective "glass table" style dock that Apple used a couple of years later in Mac OS X Leopard.
ch_sm··on FFmpeg Merges WebRTC Support
if you‘re really interested in doing that, i‘m certain you can with a bit of effort. There are plenty of docs and examples online.
ch_sm··on The David Lynch Collection
> But I was surprised by his choice of Bang & Olufsen for music. For example, his Sennheiser headphones are mostly for hearing sound as it is, while B&O always tries to 'enhance' sound in their own way. It doesn’t match much.

I feel like I can identify with that. I have a pair of AKG studio headphones for recording music and listening for "mistakes" in mixes, but otherwise mostly B&O Hi-Fi speakers. To me, the sound is more "immersive" and emotionally captivating than e.g. studio monitors, and they still have lots of detail. (Plus, there’s the issue of them looking as nice as they do and being very easy to set up — it makes them easy to live with). Just my 2 cents.

ch_sm··on Trump announces 100% tariffs on movies ‘produced in foreign lands’
> Look at all those top non-American films on that list:

That’s not a list of non-American films, it’s a list of non-American directors.

To answer what I assume is your every so snarkily delivered point: Yes, about a third of the directors on that list ended up successful in Hollywood. Does that mean international films are bad? Probably not! Does it maybe mean even Hollywood recognizes that there is a lot of international talent, and very good international films being made? Probably yes?
