This will definitely work, but it's not really even necessary. Just have some pre-connect script, that checks if the host is already "configured", and if not, then one-shot some Ansible playbook (or bash even) that installs what's needed. Use /tmp if root is not available. Also works for Kubernetes, though there we have better options.

This is the solution, but it is 1) expensive and 2) Thunderbolt cables are quite short compared to regular USB-C.

Why would a car repair shop need a website for? All I care about is the phone number, with the hope that someone will pick it up. IDK about the world, but in Poland every single mechanic I know has no downtime at all. The better ones have queues measured in weeks or months for simple repairs. They don't care about extra business, the business will find them anyway.

I believe that. Probably 95% of my support calls to online shops are about order status (aka: the website shows "in preparation" for a week already, I need to talk to a real person).

Could you suggest an alternative then? Something that is feature complete with SSH server, and also free.

Interesting, I own an E14 and it charges with 12V PD profile, stock ugreen powerbank. Maybe they differ across models?

I agree, top feature. Combined with things like "extract method" makes mundane refactorings super fast.

> I don't know how bad the spam problem was there

For every legit paper mail, I've had 5-10 garbage leaflet advertisements shoved into my mailbox by half-legally working teenagers earning $1-2/h in exchange for everyone's annoyance. 99% of these went into trash immediately without looking.

There are people like this, although very small minority. I've met one at university - he was probably the first person to have Windows 8 laptop with a touchscreen, showing off to everyone how cool is was (at that time).

He was also really good at Microsoft Word, unironically - he made extensive use of custom styling and could format an assignment paper in like 30 seconds. He was super useful in group projects.

Immediately reminds me of Severance.

I work at a company of ~200 people and I already don't recognize everyone. Seeing an unknown face, I just assume they are from some distant team that I never had to interact with, say hi and move on.

mystifyingpoi — Mon, 23 Feb 2026 18:57:40 +0000

While I've considered all the AI-inspired seasons of Sillicon Valley a bit boring and repetitive (mostly because AI is the deus ex machina there), some of this stuff actually is real now. You can actually have AI that optimizes itself.

> If your primary load exceeds 30% (CPU util), consider adding read replicas.

I'm not an expert, but isn't this excessive? In theory you could triple the load and still have slack. I'd actually try to scale down, not up.

> And you can use a local LLM

That ship has sailed a long time ago. It's of course possible, if you are willing to invest a few thousand dollars extra for the graphics card rig + pay for power.

For a machine that must run 24/7 or at least most of the day, the next best alternative to a separate computer is a cheap Linux VPS. Most people don't want to fiddle with such setup, so they go for Mac Minis. Even the lower spec ones are good enough, and they consume little power when idle.

I like that, this name tells you all about the security implications. Like, your user data could be penetrated.

> How will you maintain multiple deployments across multiple regions in the world? Backups, security patches will start to take a toll

The same way as always - by automating the crap out of it.

> How granular is the right split? Not every country has a cloud provider.

Doesn't have to be one deployment for one country, does it? Having like 3 or 4 deployments across the globe already gives you (at least) 3-4 hours of inactivity window, let's say 1 am - 4 am or something.

Exactly, that's how you do it. Having one system for the whole world is risky.

> What about things that are used by the entire world?

Well, for the remaining 0.1% - go ahead and use the fancy hot replication thingy. Sometimes there is no choice, and that's fine. Although that might mean, that the system architecture is busted.

While this is cool and I dig it, I'm really, really thankful for maintenance windows at the current job. In the real world, 99.9% of systems aren't used 24/7/365. Just do the cutoff when everyone is asleep. Then restart everything to be sure.
