overwhelmed by the response to this, I knew it was common but didn’t realise how badly people needed to see it acknowledged. fwiw, I learnt this most deeply on the react team; I joined what I thought was my dream job, and immediately failed in this fashion, leaving in a year. Quoting @threepointone new post: the senior engineer death spiral https://t.co/xzgU1jVBRh a friend just started a big job and asked for some advice. so I braindumped a monologue about a super common failure mode I see with engineers and posted it here, hope it helps whoever it can.

It's likely that more software will be produced next year than in all of the history of computing. It took Vercel 10 years to get to 1 billion deployments, but then we added another 1.4 billion in the last 10 months alone. Some of this will be tiny, personal and even disposable software. An HTML file with some javascript ("artifacts"), a report, a pricing calculator, a slide deck, all the way to sophisticated apps, agents and platforms. Deployment speed is one of our obsessions. We've brought down the time to deploy, upload, assign a domain and globally propagate an artifact to 1 second. This… Quoting @vercel_dev You and your coding agent can now use the CLI to deploy static artifacts in less than one second. ▲ ~/ vercel deploy ./my-static-site --prod JavaScript Related

Yep. Except: 1. This was about important internal tools.

I call this kind of thing 'cosplaying an enterprise production app'. All that complexity was in the way and using straight rails was perfect in that case. 2. I make calls like this all the time.

another implication of AI manifesting in real world engineering react native existed for a single reason which was to reduce the development and maintenance cost of multi-platform mobile apps. they allow you to write a single codebase (kind of) that can work on both ios and android, with a tech stack that many web devs are already familiar with but with AI being particularly good at mechanically repeating something that already exists, replicating one platform's implementation to another has become trivial in general LLMs can write a ton of code at very low cost, especially when there's a sou… LLMs JavaScript Related

Thus, the left has already started shooting while the right is still “only” mirroring the lawfare of last decade’s left.

Why Rust is different, with Alice Ryhl
3 beliefs, in the piece's order there
TypeScript
Their words
But okay, so to begin with, I think when it comes to TypeScript, Rust fits in as the backend language. That's where I would put it. I wouldn't use it in the front end. I think it's a pretty good fit for backends, API servers.

Why Rust is different, with Alice Ryhl youtube.com
JavaScript
Their words
So, here I actually think it's even stronger. The thing with C++ is that if you make a mistake, right, in in JavaScript, maybe you take down your server, which is already bad enough, but in C++ when you make a mistake there, now it's actually a security vulnerability most of the time.

Why Rust is different, with Alice Ryhl youtube.com
TypeScript
Their words
My opinion is that the least mature area is front end. There have been some attempts to compile Rust to Web Assembly and then run it on the web as a front end as a replacement for TypeScript. But if I was writing a web server, I would totally use Rust for the back end and TypeScript for the front end. I would not really go the web assembly route.

Their words
when you send someone a link to a post, they can't read it without loading the entire Mastodon frontend app into their browser, which will is a monster React codebase that will break if they have scripting disabled and also can take up to 30 seconds on older hardware.

My hot take is that JS has the lowest bar of entry to building and being productive (a good thing) but one of the highest bars of any language and stack to building high quality, stable, and reliable software. Very few devs have the expertise to pull off the latter

TypeScript JavaScript
Their words
One thing that drives me crazy about the React ecosystem, and more specifically "tech influencers" and "thought leaders" in the space, is the infantilization of the developers using and working in it. I’m tired of reading takes like TypeScript generics, mapped types, etc should only be needed and used by library authors for most use cases. Or today’s discourse; Don’t use `useCallback’, ‘useMemo’, and React.memo. If you’re building anything beyond a simple CRUD app or a an incredibly focused app with few features, you _will_ need these features.

What is a korrent?
A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
