In most of the world there is: no real willingness to solve problems nor an acceptance of people offering to solve their problems (out of pride) simply too much regulation so the problem cannot be solved without a license or long approval time very low standards of what is deemed acceptable so the problem isn't seen as a problem in the first place

The reason for this hardline stance is that we believe in the value of human thought and experience, as told by people with first-hand knowledge. It’s also about the audience: The “audience” for AI-written code is usually a machine, whereas the writing in Pragmatic Engineer is for humans, by humans. AI produces a statistical average in its output which creates uniform, dull text that’s an inferior reading experience to human writing – at least today it is.

I think it’s entirely plausible that screens have a real negative effect on teenagers, but studies can’t find them because (a) the effects need not be dose-dependent (maybe two hours on your phone isn’t worse than one hour), and (b) given that everyone else is on social media, giving it up can have a negative effect.

One of my favorite details of Sonner: By default the toast disappears after 4 seconds unless you hover over it. But what if a toast is triggered and the user switches to a different tab? 4 seconds would pass and the toast would never be seen. That’s why there’s a `useIsDocumentHidden` hook that checks if the document (tab) is hidden, and if so, it will pause the timer. This can be done with the "visibilitychange" event listener on the document. A small detail that improves the experience. Related

If you want to build a product, you should do the work: talk to customers, validate demand, think about positioning and marketing, and work to build something people will actually pay for. You don’t get to skip all the hard, boring, uncomfortable parts of building a business and then redefine success as “well, I use it.” Build for yourself or build… startups Related

With thousands of developed in a mono repo, it just does happen that one directory is missing one of the two files and this means that a subset of devs work with lobotomy. We fix this with automation but it’s a stupid complexity tax that shouldn’t have to be paid.

Most people have never heard of siRNA, but it’s going to change the face of medicine. https://t.co/RLP1pxuICA Much drug development today involves developing chemicals to fit into proteins and block them. But this almost never turns out as planned: many drug candidates get broken down in the body, interfere with other proteins and cause toxic side effects, or fail to be absorbed at all. The majority of proteins are considered undruggable, because they lack a pocket for drugs to bind, or they are ‘intrinsically disordered’, without coherent structure.

Nothing matches. Show everything
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.
