Parkytowers is site about repurposing thin clients of various kinds, it's a goldmine for finding out power consumption, Linux compatibility, possible hardware mods, etc: https://www.parkytowers.me.uk/thin/hware/hardware.shtml


Around 20 years ago when I was trying to decide on what database to use my requirement were that it should store data reliably. I learned that MySQL in contrast to PostgreSQL: 1. wasn't ACID 2. didn't have foreign key constraints 3. could loose/corrupt committed data (no WAL)

Despite me not knowing much about databases it seemed like an obvious choice.


Hell, 10 years ago (in a multi database project) I got bit by MySQL not supporting check constraints, but returning successfully when I ran the create check constraint statements.

Postgres has been great all around.


It finally supports them, which is nice. It doesn't support deferred checks to the commit, like postgres, but are otherwise good. I've appreciated using it to enforce json schema at the db level


Is there an example demonstrating what it looks like and how it works?



My problem with blockchains is that they AREN'T decentralized. If controlling a blockchain becomes valuable enough then it's a matter of time before someone will figure out how to profit from it and invest the required resources.

Decentralized in my mind means there is not one single source of truth.


So here's a challenge if anyone is up for it: Build a container orchestration engine that can run in 16MB of RAM on top of a Linux kernel.

Must have:

- Some form of networking (duh)

- Distributed state

- Distributed message queue (simple)

- Distributed scheduler

- Logging

Out of scope:

- Authorization/Authentication/Encryption

- REST/JSON/SSL/Web


Do you need all of that for a software run on a Raspberry Pi (as article suggests) or similar embedded devices? I think just one application binary should be enough.


Is there some reason all of those things could not exist in the same binary?


distributed state like memcached?

what is popular for lightweight distributed message queue?

what is popular for lightweight distributed scheduler? is cron.. "distributed"?


The main reason I thought Russia's invasion of Ukraine wouldn't cross the line of being a convincing threat was how little off ramps it left everyone involved. It's going to be hard to come up with an off ramp for Putin that is also remotely acceptable to the Ukrainian people.

>President Volodymyr Zelensky might be prepared to formally renounce his pursuit of NATO membership

If Ukrainians feel they have convincingly defended themselves against Russia that might be possible. However, in 1994 Russia signed a Treaty promising not to use military force or economic coercion against Ukraine as a condition for Ukraine giving up it's nukes. With that and the last decade in mind Ukraine is unlikely to consider a signed paper sufficient safety. Outside of NATO's nuclear umbrella they'll need a military defense strong enough to defend against Russia on it's own.

>The difficulty comes with compromises that are not fair. Why should Ukraine not seek EU or NATO membership?

Ukrainians were divided between wanting to align more with EU or more with Russia but by trying to force Ukraine not to join EU through indiscriminate bombing Putin turned a bureaucratic process into an act of defiance against tyranny. Staying out of NATO is one thing but I don't think it's going to be politically possible to tell Ukraine they can't join EU.


The lazy solution to a lazy problem


How is using more precise language lazy?


It's not, the editor banning words is what's lazy. Banning certain words is a symbolic action that makes it harder to use precise language.

If their journalists are lazy how would banning words fix that? If they stop telling journalists what words they can and can't use then maybe they could attract better talent.


I think any new journalist would appreciate a list of things that editors will find unacceptable complete with an explanation why it's unacceptable. It's better than getting your article's returned to you for being too vague.

They aren't addressing laziness, they're explaining what the standards are. And I don't think getting rid of those standards will attract better talent.


Yes you can build more wind and solar but people need power also during the dark and sometimes windless winter months. Storing enough power isn't currently feasible so it's basically either coal, gas or nuclear.


Oh no! Anyway..


Imagine sitting on a huge carousel spinning fast, like 100 times the speed of sound fast. Now imagine jumping off and trying to get to the center of it.

Yes, gravity is holding us back from yeeting of into space but to get closer to the sun you need to slow down. A lot. It takes way less rocket fuel to speed up enough to leave the solar system than to get to the sun.
