i don't think phones are THAT watertight... they're not tested for long term submersion. usualy they don't even guarantee waterproof rating for more than first two years or when there are signs of wear. should work with some non-conductive oil or fluorintert tho...

i think it's called EERAM, however having proper closed loop control with hand position feedback would be preferable in my opinion...

I beleive Android 16 now comes with termux-like Linux environment that can be enabled via developer settings menu.

Gadget mode can do more things than just network. I beleive you can set up your raspberry pi zero to work as USB mass storage microsd card reader. That seems kinda lame, until you realize you can also run transparent encryption on the raspi and unlock your SD card using passphrase entered via USB serial (also possible in gadget mode).

At first it might seem that 6 is furthest to starting point and therefore it's quite likely it will be the last one reached. However whole process is chaotic enough, that once ladybug finally arrives to 4 and/or 8, the starting position has very little impact on overall outcome.

So basically a LLM from that brief time period back when communism felt like a good idea? what can go wrong? :-)

New comment by harvie in "The Vietnam government has banned rooted phones from using any banking app"

harvie — Fri, 09 Jan 2026 17:20:34 +0000

yes. and the websites require you to verify transactions with (unrooted?) phone.

on the other hand phone does not require you to verify with your pc, so there's no second factor unless there is some unacessible secure island within the phone itself.

funny enough, you can probably use that website directly on the phone that you use as 2F, which probably circumvents the 2F idea (at least as long as you use SMS 2F instead of app that checks for root)

This is much better than the stale-bot bs irreversibly closing perfectly valid issues just because the reporter have not replied for couple weeks.

Also upstream is extremely well audited. That's a huge benefit i don't want to loose by using fork.

while (true) { if (stop) { break; } }

If there only was a way to stop while loop without having to use extra conditional with break...

article specificaly mentions rooms with poor ventilation. if you have proper ventilation, then you don't need this system in the first place, because you will get ouside air UV sterilised by the sun...

New comment by harvie in "Making Minecraft Spherical"

harvie — Tue, 02 Sep 2025 10:05:51 +0000

I was recently thinking about this... We've been building houses and other structures using plum lines and water levels all the time before afordable optics came in play. This kinda means most of our buildings are actualy polar rather than cartesian. Surely enough given the size of earth the error is quite tiny. But it's funny thinking about how the room i am sitting in right now is shaped like frustum with spherical floor and ceiling, rather than block. Despite what architecture drawing says...

Maybe we can just configure webservers to block anyone who requests robots.txt, regular browsers don't do it, but robots do to get list of urls to crawl (while ignoring rules). Just create simple PHP/CGI script that adds client IP addres to iptables once /robots.txt is accessed.

There already was a time when Steam managed to free people from need to use funny pieces of plastic in their lifes... They've done that with CDs, they can do it again with Cards.
