Not to spread concern or anything, but the electrical grid is managed and controlled by software. And that software may or may not be very reliant on AWS. I'm probably not allowed to say more than that.

Power company engineer here, it’s true that a lot of our supporting and analytics software went down during the AWS event.

However, most devices that actually control grid units (called bulk electric system cyber-assets) are air-gapped or utilize a data diode.

FERC Reliability Standards and NERC CIP

However-er, flipping through those standards just now, turns out it’s 100% permitted to connect your “bulk electric system cyber-asset” to a cloud integration if done compliantly.

The process to decide to turn power plants on and off isn't air-gaped.

So somewhere in here we need some M. C. Escher stairs of AWS on the electrical grid on AWS on the electrical grid…

Not. Electrical Scada systems are usually airgapped from the Internet.

I love this because of how often a squirrel would take down our remote disaster recovery site.

Relax, it is USB C and only a small charger, this is only 20v max, and changes are high that CC lines are the ones severed first, resulting power supply to turn of Vbus or at least downgrade to V5SAFE.

In all seriousness though, the core of the technical stack has become very robust in my opinion (DNS being the exception). From a hobbyist's perspective, things work much better than when the Web was still young. I can run multiple sites (some of them being what are today called apps) on a domain with subdomains, everything fast, HTTP3-capable, secured via valid free TLS certs, reverse proxied, all of that running on a system deployed in minutes...

If you focus on the part of the Internet that you have control over, it's a lot better than back in the simple days.

Imagine, we could kill all NAT/DNS/(reverse)proxy routing problems by adapting finally to IPv6

1

I don't only run a reverse proxy because of having only a single public IPv4 address, but that probably is the best part

In general, I'd say reverse proxies make things somewhat easier to manage, especially when it comes to TLS. No need for every service to integrate it.

We arrivied thus at the funny moment where meme is accurate enough to be used for educational purposes.

Or Fossil😅😅.

For those people wondering, it's an alternative to GIT created by SQLite devs. In fact their HomePage is actually a self-hosted Fossil repository

Can someone please keep track of the evolutionary history of these? I wanna see a timeline.

If you add infrastructure then you will need to add more transmission methods then a couple shark chewed undersea cables. Then you might as well add the millions of SAs, technicians, linemen (linepersons?), etc that install and maintain everything. Oh and I guess we would also need all the institutions and teachers that train all these techies.

So you have chosen to blatantly sin in its presence? Bold maneuver... and ultimately unsurvivable. Roll for chance of mercy, then multiply by 0.00% to determine your odds of surviving this encounter.

Can we please not make the layer above Electricity look like tombstones? I looked at "Linus Torvalds" and almost had a heart attack!

Earth: layer below electricity, melting and disintegrating

Elon Musk: boring through Earth and strapping hopelessly tiny, exploding rockets to the "Electricity" block to get everything to Mars

Sun: lowermost layer but extending a fist labeled "2027 solar flare" at internet infrastructure

It's wonderful lmao...wait,i am wrong or did you snuck anti-nuclear propaganda in the meme? Bruh

I mean, thoughts on nuclear waste? They certainly need management, and I dunno if humans are good at waste management.

I think we don't really have problems with nuclear waste management right now, at least i think in europe, idk about America or Asia so please tell me if i am wrong.

We do have one in Germany. While we are searching for suitable long term storage, the barrels are rusting away in salt mines.

If you can't make nuclear waste disappear them your always have a waste management problem.

Waste never disappear, it just get transformed in something else.

Paper? Can be recycled to be more paper or burned to be ashes and gas

Radioactive waste? Eventually it became lead, just in a long time, anyway, this was just to make you know that waste don't "disappear" like magic.

Radioactive waste can be repurposed, at least, for the majority of it, in the other cases where it can't be repurposed they try to get as much as they can from the waste(making it also less risky to manage overall) and enclosed in a reinforced concrete cage in a earthquake-safe area, in something like 50~ years it became almosts safe and can be managed again

I can only assume this (copy-pasted from wikipedia)

The C Programming Language (sometimes termed K&R, after its authors' initials) is a computer programming book written by Brian Kernighan and Dennis Ritchie, the latter of whom originally designed and implemented the C programming language, as well as co-designed the Unix operating system with which development of the language was closely intertwined

6

K&R book is great! When you're done with that I highly recommend you move on to "Modern C" by Jens Gustedt. It's available for free online or in print. Brought my C knowledge up to date with all the cool stuff C23 has in it. Jens' blog is a great resource as well.

Edit: typo

4

I can confirm, K&R is the book written by Kernighan and Ritchie. It is/was the Bible of the C language.

Amazon link if you're interested in the reviews.

4

Probably Kernighan and Ritchie. Ritchie invented C, Kernighan teamed up with him to write the first C programming book.

A company abused their clout to steal ownership of an npm package from it’s FOSS developer. Because NPM was complicit in the theft, the maintainer deleted all their packages and abandoned NPM. One of those was left-pad, which was used by tons of other major projects, which could no longer be built. NPM then restored left-pad against it’s owners wishes and handed control to another corporate shill.

Can someone ELI5 the c dynamic arrays - how does this fit into the infrastructure?

4
lemmy.sdf.org

There is a huge amount of C code underlying most things, including the Linux kernel, most compilers, the Python interpreter, etc. At the same time, C doesn’t have dynamic arrays as a built in type but they are often critical to the operation of all of those. So, C developers keep implementing them in specialized ways for all of their applications.

Thanks, I can now enjoy the meme to it's full extent again.

That's what Microsoft is doing isn't it? I knew it, we should have guessed with them sending a plain at the tower.
