Yeah, remember when we used to care about making better programming languages that would perform faster and avoid errors, instead of just slapping blockchains or AI on everything to get VC money. Good times.

Only half-joking: maybe Java was a mistake. I feel like so much was lost in programming language development because of OOP...

Yes, but computer chips are powered by DC.

doliveira · 2 years ago

As long as you don't keep switching the DC current on and off, which is what computers are all about

You can try pip install pillow for a good example of how it works. I suspect there's a strong survivorship bias here, as you'd only notice the packages that don't ship with wheels.

doliveira · 2 years ago

Yeah, perhaps. One I remember from last year is the cryptography and numpy package, for instance. Now they do seem to ship with binary wheels, at least for my current Python and Linux version.

Kerberos and Hadoop stuff obviously still doesn't, though. I guess the joke's on me for being stuck in this stack...

Probably a function of the specific set of packages you use, or the pip options you specify. Pretty much all the major C packages come as wheels these days.

doliveira · 2 years ago

They all come as wheels, they just aren't precompiled.

At this stage [0], uncompiled native extensions are not yet a bug, but a definite oversight of the maintainer. They should come as precompiled wheels

Honestly I don't think I've ever used a precompiled package in Python. Every single C stuff seems to take ages and requires all that fun stuff of installing native system dependencies.

Edit: skimming through this page, precompiling seems like an afterthought, and the linked packages don't even seem to mention how to integrate third-party libraries. So I guess I can see why it doesn't deliver on its promises.

Like not everyone toy app isn't going to be the next FAANG, there are plenty of workloads where it hardly matters, while 30 years later it is still a mess in C and C++.

And between C++ and Rust coroutines, still not sure which one I like less.

doliveira · 2 years ago

I thought so too until I got to interact with databases and Big Data tools written in Java. God, what a mess that requires so much upkeeping, more dependency problems than I remember from C++ and probably some orders of magnitude more resources than they should.

The existing finance system is largely reputation based, with a light side of contract enforcement and a heavy dose of middlemen. It mostly works, but one of the biggest advantage of crypto stuff is removing the need for reputation and trust.

doliveira · 2 years ago

Is that an advantage? At the very least, what it entails is that losing your private key is game over.

bluefinity · 2 years ago

I'm not sure Elbakyan receiving this award is particularly appropriate, considering she is strongly pro-Putin and is a big fan of Joseph Stalin (she regularly quotes him on VK).

doliveira · 2 years ago

I mean, that sucks, but honestly she's not a ~digital influencer~. So I don't think her views matter that much.

Nested CSS is supported in the latest version of all major browsers.

That's not the point...

doliveira · 2 years ago

I was watching a video about nesting in CSS and how it's just in Chrome and comments were all about how cool it is and how they can't wait to use it, and so on, and so forth. I think it's quite a representative example: we can do that much better with SASS today, but I guess Google needs to keep features pushing at full speed so no one else can keep up.

We developers are so gullible. Just give us some shiny things and we don't even realize they're heating up the pan.
