If there is not enough supply for the demand in housing then nothing but meeting demand with new supply will solve that.

I highly doubt they destroy digital copies of the books after scanning. They will want to train their future models on the same content. So what prevents them from making these digital copies available to the public? Copyright!

Just have your agent use an existing design system. They provide coherence and many styles to choose from (and customization if you really need that for your personal use). I wouldn't expect agents to invent a coherent component librar

I don't think that needs to be true either anymore. Exhaustive specifications and comprehensive test suites are easily created now too. That's why I think software engineering will not go away, it will just change drastically.

It's actually a combination of both, leaving out more expensive smaller markets.

And what would the goal of that be? I thought the goal of education was... education. The grading is not goal in itself. Will this really motivate kids to do better?

Sounds like a great opportunity for kids in high school to learn how to feed back the AI detection results into the model and have this process be automated. Next level would be fine tuning the model via reinforcement learning and sharing i

Dependencies. There are billions of lines of C++ out there that have been optimized and production hardened over decades that you might want to reuse. Rust lang interoperability with anything but C sucks in practice.

I generally agree, but max line length being so high you have to horizontally scroll while reading code is very detrimental to productivity.

> What caused the drop in popularity in RoR? Async/await. JavaScript and all other modern languages and frameworks have a great concurrency story. Rails still hasn't (but it's coming next year, it's been coming next y

I disagree. Hiding async makes reasoning about code harder and not easier. I want to know whether disposal is async and potentially affected by network outages, etc.

I think you should appreciate more how much the tens of billions of dollars Google has invested in Chrome has benefited the web and open source in general. Some examples: Webrtc. Google’s implementation is super widely used in all sorts of

Aside: it’s impressive how the whole blog post does not mention a single detail of what they actually did to achieve these performance improvements. Code changes, really?

There is also the question of cause and effect. Did Instagram grow to what it is today because of a decade of investments from Meta?

The point of deterrence is that you spend the money so the chance of Russia doing something like a land invasion of Europe is decreased. The much more likely scenario that Europeans are wanting to prevent is a limited invasion in the Baltic

We need to invest a lot of money to stop climate change. Renewable energy projects are very capital intensive compared to fossil fuel equivalents.

This ironically applies both to climate change and being a decade too late to react to Russia's expansionist actions.

You're being overly dramatic. Germany has been spending low amounts of money on its military for two and a half decades. Circumstances changed and spending needs to be increased to adjust to the new situation. This is not militarizatio

The Rails documentation has lots of info about this: https://guides.rubyonrails.org/tuning_performance_for_deploy... Concurrency support is missing from the language syntax and this particular library as a concept. This is

Yes, it does. Ruby has a global interpreter lock (GIL) that prevents multiple threads to be executed by the interpreter at the same time, so Puma does have threads, they just can’t run Ruby code at the same time. They can hide IO though.

Rails is a hot ball of global mutable state. Good luck with threads.

Unfortunately, 5 years after the release you linked, almost none of this has made it to Rails or even to relatively new libraries this post is about. The reason (imho) are unfortunate design choices in how the language incorporates concurre

The API looks nice on the surface, but this will be expensive to operate due to Ruby and Rails’ lack of support for concurrency. Everything is blocking, which is not a great match for the async nature of interacting with these models.

This will synchronously block until ‘chat.ask’ returns though. Be prepared to be paying for the memory of your whole app tens/low hundreds of MB of memory being held alive doing nothing (other than handling new chunks) until whatever s

I don’t know why “number of companies using language X” is a metric that is used here. Wordpress is serving 43% of websites on the internet as of 2025, so we should all be learning PHP!
