From what i read they are going with "partially painted black" Makes sense to only have the underside facing earth black. Also the satellites underside is only exposed to the sun with an steep angle because most of the time when i

Black satellites are nothing new. Just ask any Surveillance Agency how they handle the heating problem due to black paint. Oops that's classified. But probably such satellites need a dedicated cooling system. It's never as easy as

Yep. The OpenBSD bootloader reads an entropy file from hard disk, mixes it with RDRAND from CPU (if available) and passes it to the Kernel. The Kernel starts an ChaCha20 stream cipher with this supplied entropy while constantly mixing in ti

That's why OpenBSD cut away the start of the RC4 stream (don't remember how many bytes) to make backtracking harder. But the point is mood b.c. the stream cipher used switched from RC4 to ChaCha20 like 5 years ago. And there is no

So like the standard arc4random_buf(3) which everybody has except for Linux. Don't worry the name is historic it does not us the arc4 cipher any longer, at least on OpenBSD. They switched to chacha20 as stream cipher.

sshd is mentioned (1.5) exactly because sshd did catch this and refused login. So no, no remote exploit in the default install. But it was close :)

You are referencing a Linux manpage. But if it's also true for OpenBSD those syscalls will get deleted or a libc wrapper will be introduced.

Nothing wrong with using goto, sparingly. It's the preferred way for error handling in C. Nobody has code like this anymore 10 I=1 20 PRINT "HELLO " 40 PRINT %I 50 IF (%I > 3) 10 40 30 PRINTLN "W

The desulfator i speak about is powered by the 12V battery itself. It's a small box with just get hooked up to positive and negative. Technology differs but basically it charges a capacitor and produces very short high voltage charging

Lead batteries can be rejuvenated, with a device mostly called "A pulser/desulfator/refresher" Short story: I had a completely dead 12V car battery. It was at 0V and would not accept a charge at all. Connected it to a be

Yes it's a new CLI front-end. In fact it's a BSD/ISC licensed reimplementation/reimagination using the git repo structure for file storage. Commands differ a bit and knowing the OpenBSD developers, it will be more consis

It's just 3 phases with 230V each, which gives you 400V across individual phases. Same safety rules apply as on standard outlets, so yes, it really is just familiarity. Also lots of European households do have 400V outlets (we have 2 i

by ben_bai 7y ago
Nitpicking: 230V +-10%, so on a good day it can be as high as 253V. But yes most people will work on it for their own, but shy away from 400V outlets.

It was setuid root but dropped privilege, but the dropping privilege came after parsing the command arguments and doing initialization, so there was a small time window while it still runs as root and in that time it could be tricked into o
