The response is ChatGPT.

They're going to add ads to their responses (if they didn't added it already), and people use it as search engine.

Maybe I'm reading between lines, but isn't it ridiculous to talk about license prices when the affected machines are $900 pro laptops?

I mean, I understand that in a cheap single board computer, but this is nonsense.

I knew about the difference they have between UNIX-like OSs in the usage of different signals (and the System V vs BSD battles, between others), but I didn't know Windows didn't have a similar system (I haven't done too much low-level in Windows).

Thanks for the long comment!

I knew some changes (like STL containers) came from Boost, but I didn't know those also came from there, and specially since such a long time!

That means I need to look more Boost documentation :)

I really like how some good structures used by other languages, specially Rust and Zig, have been added to the newer C++ standard.

The Result, Optional, and Variant are really sweet for day-to-day use of the language, and those in-process standard libraries of SIMD operations, BLAS mathematical functions, and the the execution library looks really cool, specially as standard.

I would like C++ would be a little more "batteries included" in some ways, like having a basic standard for signals, networking (just handling sockets would be a huge thing), and some basic system calls.

I wonder if some Apple-made software, like Final Cut, make use of all of those "duplicated" instructions at the same time for getting a better performance...

I know how just the multitasking nature of the OS probably make this situation happens across different programs, but nonetheless would be pretty cool!

We already have some USB-C flash drives. Isn't just more practical to have USB-C keyboards, mice, and other devices like that instead of conserving the USB A?

IIRC some countries, like UK, have a similar thing like Credit Score, mostly used for what type of loans they can give you, max credit card limits, and other financial products, but won't affect at all to buy a car in cash or renting an apartment.

For me it's crazy not being able to rent a place even paying a whole year beforehand.

You can avoid this problem easily not letting students using phones or computers in the classroom and making doing more tasks at the classroom than at home.

If you're going to say "but in a working environment you use a computer", then teach them how to use text processing and spreadsheets int the computer room, a thing that didn't happen today in most schools btw.

In my Uni we still had some coding test done with pen and paper (2014-2018), and AFAIK, they're still doing them. I even done a part of an exam in assembly with a provided Xilinx PicoBlaze assembly mnemonics list.

I don't know why people demonize them. If you know the syntax you're asked for, you can write in that language, and if you were asked to write in pseudo-code some algorithms, you should be able without any additional computerize help.

I remember in the mid 2000s how some Xara Designer illustration software was able to do that, I don't know how isn't a more common thing (or maybe I don't know enough specialized software in that matter).

I remember well that program because it was available both for Windows and Linux, a really rare thing in that time.

IMHO yes. Sometimes if the deviation is too big yo can get coocked, overcooked, and mostly raw pieces in the same pan, and that's heavily undesirable.

Some European Diesels have reached that amount with the same engine block and head ;-)

My dad's BWM E60 has a M47 2.0L Turbo Diesel, and with around 440,000km keeps going strong.

He probably will change it when it reach the half million due to being an old car, but the sad part here is how we won't probably be able to buy any brand new car that could reach that amount of miles without spending a lot of money on the way on repairs.

Imagine how things are going on that MB are using petrol engines from the Chinese brand Geeky.

Even tech influencers who love React, like Theo Browne, has heavily criticise how bad is made GitHub in that regard.

IIRC they set the diff page to update entirely every reactive element in the page when some of this element change, instead of that one.

Hyundai/Kia are fine in Diesel engines, electric power trains are giving plenty of problems, and their 2.5L petrol engines are incredibly bad.

Outside that, they are cheap cars, and mine after 10 years have some paint chips even peeling.

It happens the same to me. Probably we don't experience that because we don't either buy any cheap garments from Shein or similar Chinese stores.

I would add that sometimes when people usually say that rancid phrase of "they don't make it as they used to", they are comparing expensive products in the past with cheap ones in the present.

Most of those "good 'ol" goods exist, but probably are pretty/too expensive for what we are used to pay.
