along those lines I think I mentioned it in here before but a few years ago I tested an “IoT” satellite link that was effectively like 9600 baud and low priority so had ping times on the order of 2 seconds. it is not possible to complete a normal “best practices” ssl handshake with that

in other “what are we even doing anymore” old man yelling at cloud topics I just had to increase the disk space on a build vm because 40 gigs wasn’t enough to build a small yocto image

cell processing at the time was trying to get in front of the heterogenous computing pipeline but the whole cool poo poo about the spu and ppu and etc could not hold a candle to the raw processing power of gpgpu cards but it sure made headlines for the ps3-based clustered supercomputer that the us air force made because ps3s were sold at a loss

I wouldn’t have expected such a mess with the former but I guess I’m not surprised solidly GAA, a lot of new connections are cbrs (20% of 2000-ish) but the financial reality of a small company to spend $100k on 10Mhz of PAL was pointless. everyone else is 10 times the size and just poo poo up 5ghz so cbrs has been useful, just like 6/11ghz licensed stuff has been

There is another article that I can't find again where a small community in a desert town made an analog cell network based on some MIT grad project or something.

This seems a particularly bad fuckup. I'd guess most pixel phone users have something hidden at risk of being revealed because of this. Also, my pixel lists itself as up to date and yet I could still use the demo app on a heavily cropped image, successfully recovering have the image perfectly and the other half approximately. Aren't these meant to be fixed at least going forwards before being publicised?

they were opening the existing file in write mode and then writing the new data. so they just overwrote some prefix of the data and the rest of the file was still there the android api used to truncate when you did this, but apparently they changed that in android 10. that patch is here. it is unclear from the patch whether this was intentional. you’d think the author would call it out explicitly in the commit message as a behavior change if it was intended. otoh he also added an explicit test for the new behavior, and the original code gave him very obvious data and structure for the test which he chose to not use you’d think this was a pretty basic operation to break behavior on. but these strings are actually pretty unusual, i think — it’s an idea from the c standard library being imported into the android api. the standard java file apis do not take these strings, so unless they’re implemented with them behind the scenes this only affects people using specific android platform apis. fwiw in c “w” is specified to truncate, so i don’t know what the gently caress this dude was thinking also this is a very deprecated way to overwrite a file anyway — you lose data if the operation fails. so that helps explain why nobody was kicking down the door when they broke it

i'm just confused as to why they didn't just write out an entirely new file. PNGs are lossless, it's not like you'd be getting generational loss or something, and you'd get a better compression ratio anyway

how did nobody notice that a cropped image had the same file size as a non cropped image? this is the most confusing thing to me. or am i misunderstanding something?

mystes posted:They're presumably rewriting the entire file anyway. It shouldn't really affect performance or the content of the new data that's being written (ignoring the part that was supposed to be truncated). they're not. it overwrites only part of it ...but that writes a new IHDR and IDAT chunk i guess (otherwise the image would still be completely visible), so it's being compressed again anyway? the whole thing is very confusing lol
