I think you overestimate how much vape companies care about safety. When there is no liquid left, you just vape smoke from burning cotton (it tastes like burned plastic) on half of these devices. There are checks for this, but they are not that good.

I'm sure most don't care more than regulations require them to care (including making tradeoffs in terms of risks of getting caught, and the chance of actual enforcement). But that doesn't change the fact that it is a safety-critical device. It produces something that interfaces directly with sensitive tissues.

I talked to someone who worked on developing vapes and they spent much, if not most, of their engineering on safety-related issues. They may be an outlier. The reason I remember is because I was surprised how dangerous these devices really are if you get things wrong.

As a software engineer with some hardware experience, I would never use a vape. It strikes me as way too risky. Much for the reason you point out: the companies probably don't care more than they are forced to by regulations.


Yeah, especially when a CSS library makes $1M a year. I guess they have no incentive to improve funding.

Temporary splits to run code close to the editor, tmux popups (they open lazygit or file manager on top of the current tab). Debug runs, where I want to preserve their output for some time, so I keep them in separate tabs.

Battery life and performance on MacOS

Guido gave up the idea of keeping CPython interpreter simple. It's now a complex beast with JIT and a lot of small optimizations.

It’s still pretty profitable, more than $100k a month

Revenue is not profit

With TC of $250k. There is a lot of room for optimization.

People overestimate the impact of toxicity on number of monthly questions. The initial growth was due to missing answers. After some time there is a saturation point where all basic questions are already answered and can be found via Google. If you ask them again they are marked as dups.

That would be true if no new technologies were created every year (even more often).

There are new technologies, but if you look at the most viewed questions, they will be about Python, JS, Java, C, and C++ without libraries.

You do not find the 2009 jQuery answer satisfying?

   > Strings
   >The rule of thumb for strings is the core string object takes 41 bytes. Each       additional character is 1 byte.
That's misleading. There are three types of strings in Python (1, 2 and 4 bytes per character).

In Go, hashmap implementation is pretty low level. Even linker carries some parts of its implementation details.


Huh, that's pretty cool. Do you happen to have any links pointing at any of that stuff?

Here linker relies on the current memory layout. Changing it requires updating linker code as well.
