Yes, it is Borg. Not k8s. Granted it is similar

The legit use case for companies like Google/Amazon etc is only to sell it to customers. None of these companies use K8s internally for real critical workloads.
rantanplan··on Features I wish PostgreSQL had as a developer
It would be easy to create a script like that. You'd save quite a significant storage space, especially when you have tables with hundreds of millions of rows. The real problem though is with further migration of your schema down the line, where you're going to add/remove columns, as it's almost always the case.

rantanplan··on If you’re not using SSH certificates you’re doing SSH wrong (2019)
Yes, SSH certificates are the way to go and pretty easy to set up. But what these articles fail to address is the user management aspect.

For the SSH certificate to be accepted, the unix user must first be present on the system. As far as I can understand, FreeIPA(or similar LDAP systems) cannot be used in conjunction with SSH certs. Whereas SSH keys are supported by these systems.

Can anyone provide any insight/experience with this?

rantanplan··on Can you warm yourself with your mind?
> What is astral projecting?

The illusion that your mind escapes your body and/or visits other planes of existence etc. It has been replicated successfully in lab conditions many times over and is proven to be just an illusion.

Got it, thanks.

Search for "Ben Finegold" on YouTube. He has many lectures for beginners and he's one of the funniest GMs. That makes it less boring :)

> PG doesn't have a way to tell it how to organize data on disk so there is no good way around this (CLUSTER doesn't count, it's unusable in most use cases).

Aren't tablespaces (https://www.postgresql.org/docs/10/manage-ag-tablespaces.htm...) supposed to help with that?

Haven't used them, I'm honestly curious

rantanplan··on What the Fastly outage can teach us about writing error messages
I haven't met that many bridge architects :D

But do they build bridges by themselves? Are bridges built by a one man show?

And they don't have rules? And how do they get anything done?

rantanplan··on What the Fastly outage can teach us about writing error messages
> Are you aware that those things go through a design phase with the explicit objective of giving them a personality, right?

Not really. I see quite the opposite; during the design phase the team sets the rules in order to guarantee consistency and cohesiveness and avoid any deviation from what has been agreed upon. This rules out personal or whimsical contributions, because by definition it would ruin the process.

> Anyway, it's not like you can avoid giving your software a personality. You can't.

I alluded to that, if you re-read my comment, but a software having its unintended whims, compared to intentionally trying to give it some "personality" is not the same thing at all.

rantanplan··on What the Fastly outage can teach us about writing error messages
Because we haven't solved the main problem yet, which is to create robust software that does exactly what's supposed to do, no more no less. We have opinions, we have some indications of what may improve software development, but we are far away from comparing software engineering with other engineering domains. And it's only logical, because compared to other disciplines, software engineering is in its first baby steps.

Imagine if construction/aviation/etc engineers wanted their building/bridge/airplane to be whimsical and have its own personality. Are you scared yet?

Imagine if your out-of-band(not in the initial requirements/spec) and whimsical software contribution was responsible for a bug that brought down an airplane, or killed a patient. How whimsical would you be then? Well at least you wouldn't feel bored at your day job right? Anyway, I think you get my point.

rantanplan··on What the Fastly outage can teach us about writing error messages
> Software is a highly personal and creative thing, it should have a personality

Not it isn't and it shouldn't. The process of creating the software is; huge distinction.

The product of your efforts should not have a personality or feel personal, it should just work as intended. Software is hard as it is and we don't need to make it more whimsical. A little experience can teach us, that whether we like or not, it will ultimately exhibit its own whims anyway.

rantanplan··on Movies every physics lover should watch (2020)
I am not analyzing the realism of the physics, I'm not qualified for that. Physicists say it's realistic enough and I believe them.

But realism in the science aspects of a movie shouldn't be an excuse for a lack of a coherent story or bad character development.

I respect your take and what that movie means to you, but don't think that I didn't want to immerse myself in it or anything like that. I was highly anticipating this movie for years. It just didn't do it for me.

rantanplan··on Movies every physics lover should watch (2020)
This is not related at all to what happened in the movie.

We're not talking about experimenting on people (thus causing accidents/deaths/etc) but about withholding new knowledge.

rantanplan··on Movies every physics lover should watch (2020)
Doctor Hugh Mann and the whole narrative around him was one of the most cringe-worthy moments I've seen in a movie of that caliber/budget.

The motives behind the characters (Anne Hathaway's character deciding to sacrifice humanity to see her boyfriend, Caine's character withholding physics advancements for years, Murph's whole behavior... and so numerous others) was, objectively, bad writing. Of the kind that you really wonder how it got out in the public and into such a high profile movie. I can't think of a single person in that movie that acts realistically. To the point that I kind of believe that the "plot" was just a pretext for Kip Thornes awesome work on the visualizations of the wormholes.

The plotholes... well way too many. That was the movie that ruined Nolan for me. Up to that point I was a very big fan.

rantanplan··on Archaeologists uncover ancient street food shop in Pompeii
No we don't! How dare... um... ok yes we do struggle. Unless you're an ancient Greek teacher, it's very hard to make sense of it. But you can certainly pick up numerous -unchanged- words or roots(common parts) since modern Greek is derrived from them.
rantanplan··on Red Hat Goes Full IBM and Says Farewell to CentOS
The problem was not Fedora per se, but GNOME and especially Wayland. Wayland is slightly above vaporware and infested with bugs.

Had you chosen Fedora with KDE you'd probably have 0 problems. I'm using it without any drama for 11 years and I keep suggesting it to co-workers and friends.

Wayland has done so much harm in the Linux ecosystem and that gives me a lot of grief :(

Incidentally I can't connect to HN directly from Greece, but only if I use my VPN through New York. Probably somehow related?

Not directly comparable. You can use iptables on a EC2 instance inside a VPC.

VPC is more akin to a glorified virtual switch/bridge.

Kubuntu is, and always has been really bad, as a KDE distro. Just use the Fedora KDE spin. I've been using it for the past 10 years or so.

Math is science, so no one cares if they don't believe in it. The above is not.

All of your remaining assumptions are wrong, so no reason to even bother.
