Right. That’s why all the software from, say, Microsoft works flawlessly and at peak efficiency.
This. It's exactly why Microsoft use modern frameworks such as React Native for their Start Menu used by billions of people every day.

That’s not what I said. Only that the responsible engineers know which tradeoffs they make, and are competent enough to do so.
The decision to use react for the start menu wasnt out of competency. The guy said on twitter that thats what he knew so he used it [1]. Didnt think twice. Head empty no thoughts 1 https://x.com/philtrem22/status/1927161666732523596

Please do share any evidence to the contrary, but it seems that the Tweet is not serious and is not from someone who worked on the Start Menu.
I found this: https://www.youtube.com/watch?v=kMJNEFHj8b8&t=287s I googled the names of the people holding the talk and they're both employed by Microsoft as software engineers, I don't see any reason to doubt what they're presenting. Not the whole start menu is React Native, but parts are.
The overlap of people that don’t know what TCP Slow Start is and those that should care about their website loading a few milliseconds faster is incredibly small. A startup should focus on, well, starting up, not performance; a corporation large enough to optimise speed on that level will have a team of experienced SREs that know over which detail to obsess.
This idea that performance is irrelevant gets under my skin. It's how we ended up with Docker and Kubernetes and the absolute slop stack that is destroying everything it touches. Performance matters. We've spent so many decades misinterpreting Knuth's quote about optimization that we've managed to chew up 5-6 orders of magnitude in hardware performance gains and still deliver slow, bloated and defective software prod…

Can you live fork containers like you can VMs? VM clone time is surprisingly quick once you stop copying memory, after that it's mostly ejecting the NIC and bringing up the new one.
I can't say I've ever cared about live forking a container (or VM, for that matter)
Our cluster keeps stats on when processes start. So we can alert on crashes, and because new processes (cold JIT) can skew the response numbers, and are inflection points to analyze performance improvements or regressions. There were no restarts that morning. So they pulled the tablecloth out from under us. TIL.

Containers were invented because VMs were too slow to cold start and used too much memory. Their whole raison d'être is performance.
That's another reason they're so infuriating. Containers are intended to make things faster and easier. But the allure of virtualization has made most work much, much slower and much, much worse. If you're running infra at Google, of course containers and orchestration make sense. If you're running apps/IT for an SMB or even small enterprise, they are 100% waste, churn and destruction. I've built for both btw. The co…
Building disk images was a giant pain in the ass but less disruptive to flow than having QA cry wolf a couple times a week.
I could do the same with containers, and easier.

Docker good actually
nah - we'll look back on Docker the same way many of are glaring at our own sins with OO these days.

> a corporation large enough will have a team of experienced SREs that know over which detail to obsess. Ahh, if only. Have you seen applications developed by large corporations lately? :)
a corporation large enough to have a team of experienced SREs that know which details to obsess over will also have enough promotion-hungry POs and middle managers to tell them devs to add 50MB of ads and trackers in the web page. Maybe another 100MB for an LLM wrapper too. :)
The article has IMO two flawed arguments: 1. There is math for how long it takes to send even one packet over satellite connection (~1600ms). Its a weak argument for the 14kb rule since there is no comparison with a larger website. 10 packets wont necessarily take 16 seconds. 2. There is a mention that images on webpage are included in this 14kb rule. In what case are images inlined to a page’s initial load? If this…
> In what case are images inlined to a page’s initial load? Low resolution thumbnails that are blurred via CSS filters over which the real images fade in once downloaded. Done properly it usually only adds a few hundred bytes per image for above the fold images. I don’t know if many bloggers do that, though. I do on my blog and it’s probably a feature on most blogging platforms (like Wordpress or Medium) but it’s mor…

Talking about video streaming, I have a question for big tech companies: Why? Why are we still talking about optimising HTML, CSS and JS in 2025? This is tech from 35 years ago. Why can't browsers adopt a system like video streaming, where you "stream" a binary of your site? The server could publish a link to the uncompressed source so anyone can inspect it, keeping the spirit of the open web alive. Do you realise ho…
I see you mistake html/css for what they were 30 years ago „documents to be viewed”. HTML/CSS/JS is the only fully open stack, free as in beer and free and not owned by a single entity and standardized by multinational standardization bodies for building applications interfaces that is cross platform and does that excellent. Especially with electron you can build native apps with HTML/CSS/JS. There are actually web a…
