I hate ads too but whats the outrage? Did people expect it to be free forever? Everything else has ads. youtube, instagram, x, google etc. etc.
You can't trust a product that uses ads, because then you are the product.

This is already hyperbolic; in most countries where software engineers or similar knowledge workers are widely employed there are welfare programmes.
To add to that, if there is such mass unemployment in this scenario it will be because fewer people are needed to produce and therefore everything will become cheaper... This is the best kind of unemployment.
So at best: none of us have to work again and will get everything we need for free. At worst, certain professions will need a career switch which I appreciate is not ideal for those people but is a significantly weaker argument for why we should hold back new technology.
If you were to rank all of the C compilers in the world and then rank all of the welfare systems in the world, this vibe-coded mess would be at approximately the same rank as the American welfare system. Especially if you extrapolate this narcissistic, hateful kleptocracy out a few more years.

I just today realized io_uring is meant to be read as "I.O.U. Ring" which perfectly describes how it works.

This seems incredibly inefficient. Is there a future for hybrid aircraft, which would feature both traditional turbofans and large batteries for energy storage?
Batteries would eliminate the need for an APU and power the aircraft during taxi, allowing the engines to be started just before actual takeoff, and shut down immediately after landing.
Either the batteries could power wheel motors directly during taxi, or the aircraft could mix turbofans with e-fans (which could also allow energy recovery during descent and help power the aircraft during cruise, reducing fuel consumption further).
eTAXI is just one such solution

> You’re already flying this route with a 300-seat plane where 80+ people in business class generate most of your profit. Give those passengers a supersonic plane, cut the flight time in half, and charge the same price.
What does that end up doing to the cost of a seat in coach?
Haven’t seen a loading progress spinner on a landing page in a while. The Ruby website now loads almost as slowly as Ruby on Rails boots up.

Clean energy is pretty controversial in US. Most people are against it.
“Most people” is not even remotely accurate.
jelder commented on SQLite JSON at full index speed using generated columns dbpro.app/blog/sqlite-jso... · Posted by u/upmostly
It works until you realize some of these usages would've been better as individual key/value rows.
For example, if you want to store settings as JSON, you first have to parse it through e.g. Zod, hope that it isn't failing due to schema changes (or write migrations and hope that succeeds).
When a simple key/value row just works fine, and you can even do partial fetches / updates
The necessity of using a JSON column was outside of my control, but Zod etc. are absolutely required, I think, in most projects. I wrote more about that here: https://www.jacobelder.com/2025/01/31/where-shift-left-fails...
