Why is this attitude so pervasive? It's akin to writing backend and saying you should avoid Postgres altogether and use text files saved on the hard disk.

Just got back from a run! By far the most effective thing to motivate me to exercise, and run in particular, is the "VO2 Max" section of the Apple health app. It's a rough indication of your cardiovascular endurance, and the

> Vanilla HTML, CSS, and JS This is a non-answer. It only really is an admissible solution if you're just working by yourself. React solves real problems when building web applications. If you use vanilla HTML, CSS and JS, you'

Like I said, React has nothing to do with the slowness issues of messenger.com.

That doesn't say much about React, though. Indeed, you can open the network panel and watch requests go by over the seconds that it takes to open, suggesting that the issue likely resides on the backend.

This article is better, but has very little to do with React. The major issues I see are 1) loading a 2.5 MB AWS library (not React), 2) not doing SSR (not React) and 3) not tree shaking (not React). I agree these are all problems. But shou

I've spent plenty of time optimizing performance. It almost always comes down to a backend issue, unless the frontend is doing something profoundly stupid, like making multiple API requests in serial when they could be batched or paral

I didn't say it does? I am just spliting hairs over the definition of framework.

Is it? On Hacker News it probably is, and I agree that it can drive engineers nuts to know that apps are more bloated than they have to be, but I think we’re a relatively small percentage of the population. Among my less technically/in

I agree with most of what you said. As a minor nit, my understanding is that you call into a library, whereas a framework calls into you. Since React typically does most of the calling into my components I think it’s fair enough to call it

Reading over the authors primary reasons to not use React, they strike me as fundamentally misguided - mostly solving problems that most people don’t have. One reason it says that React is a poor choice is performance issues. But front end

The notion that there are only two options: that your superiors should be perfect receptors of all information, no matter how poorly phrased, or that you should begin "polishing your resume", is immature. The world is more complex

I think a more charitable interpretation of the title is an implication that the other material written for Janet was written for supergeniuses (or whatever), so here's a book finally written for normal people.

Pretty poor article - not a single code sample, just vague generalities that I could have listed off without ever touching a LLM. I suspect this is just a disguised advertisement for Qodo.

Hm, I think that Amazon shows that just user votes might not be sufficient - e.g. because users can be paid off to give 5 star reviews, which bias the results.

I think I'd be pretty happy if Consumer Reports was on the top for queries like these (if they had the relevant data, of course). I think they follow your criteria pretty closely.

This is a rant I’ve had in my head forever, so thanks for posting this. A lot of people use the proof that the halting problem is undesirable to make some deep philosophical point, like this one. But the actual proof is so disappointing and
