Funnily enough, to me these aphorisms (?) sound almost like the replicant test in Blaze Runner. Like these are the unit bit of "nudging"

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

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

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...

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

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.

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.

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

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

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.

Yeah, financial and social pressure is basically the only weapons we have against corporations when regulations don't exist. And honestly, financial pressure doesn't work at this scale or in this case.

I have 4 banking apps and about 8 government apps in my phone. All of them require device attestation. I have no doubt they will use the Web Integrity API as well.

Even if they don't, a lot of websites are just breaking on Firefox. The development community decided they want a Chrome monoculture.

Do you know how rooting Android is basically useless nowadays? Most banking and government apps, at least in my country, don't work if Google didn't give the seal of approval for your system. I take it you see as good thing to bring this to the browser as well, because this somehow has to do "personal computer advocacy"? It literally cripples the users' devices.

Nah, scientific papers are supposed to be precise and technical. This reads like those quite frequent suggestions here of switching all equations in papers to plain English or code: it honestly comes from a place of ignorance, and I say that as basically a layman myself.

What should be encouraged is for academics to blog about their research as well. It would even help when recruiting and onboarding new members. Right now the sociological and economical incentives don't promote this at all.

Yeah, I'm interested in knowing how people manage it. With Redis, I usually put the Lua code within the same repo and embed the Lua code within the deployment artifact, so it gets tested and deployed together with the rest of the code. Then I call SCRIPT LOAD at the application initialization and I get a SHA-1 hash to call the script.

At the very least, this approach makes things feel much safer. I would like to know if there better ways to do it, and if there are similar approaches for Postgres procedures.

Yeah, I find it funny to see technologists being surprised that in most cases judges won't mind that the signature wasn't done with quantum-resistent cryptography stored in a blockchain or whatever. Technical solutions to political problems...

The common thread is these are utilities, not VC-backed start-ups wanting to dominate the world.
