Doesn't this mean that the broken device also answered to every ARP request? And wouldn't that break the network by itself, regardless of DHCP behavior?

Makes sense. I was thinking that maybe signal handlers could use the regular stack of the thread, but that would of course make everything fall down if the "real" code would write …

Oh yeah, I didn't think of that. I wonder if you could write a signal handler carefully to not allocate any memory, stack or otherwise, or is some return address or an internal str…

What happens if you really run out of physical memory (including swap) after overcommitting? Does your process get a signal, or will OOM killer just run without notifying the proce…

My dad used a 3D printer with a Dremel attached to carve PCBs. The PCBs were those that you normally etch, i.e. they had a full copper coating.

This one's my favorite (although I haven't read the whole thing): "This movement is designed to double the speed by gears of equal diameters and numbers of teeth—a result once gene…

I can imagine some timing-specific attacks for memory accesses, but they're not likely as robust as attacks against the branch-predictor: 1. This is the simplest one - if the memor…

- Random stuff all over ~/ - User-specific bin folder ~/LocalApps (with lots of scripts) - Projects etc. in a GoCryptFS-encrypted directory synced with Syncthing with NAS (with NFS…

I spent yesterday rewriting my ZSH config. A lot of the time I spent on figuring out how to map random key combos to unused control characters. So if I could implement both the ter…

Its port 26 enforces TLS though.

Requiring the same standard of verification for activating an account. Of course, they want to make it easy so it's unlikely to happen...

The point was that you could more easily replace the SSH server with a malicious one and e.g. hijack your agent when you connect to it.

I'd be very cautious before moving SSH to a non-privileged port (over 1024). Any user on the server might start their own SSH server on the port assuming the real SSH server is dea…

That's not the server's fault, it's just Drupal being slow. It was pretty slow in version 6 and has been getting consistently slower. I'm pretty sure that the request count is for …

Awesome! I didn't even think that you could do that without breaking the lock apart.

Couldn't you reverse-engineer the master key from a lock anyway? Or is there some clever design preventing that?

It reads the next number in the list, it's not a random lookup. See https://github.com/id-Software/DOOM/blob/master/linuxdoom-1....

Besides drafting, EDH is a good format if you don't want to spend too much. When you have a 100 card deck with only unique cards (except for basic lands), people generally don't wa…

I think it's JMP due to tail-call optimization. If there's a JMP, the RET of the inner function (bar) returns from the outer one (foo) also, and one unnecessary jump is eliminated.…

If the message had some information about the Tiananmen Square massacre or some other censored information, the attack would probably stop. At least temporarily.

An interesting mechanism using differential gears, doubling the speed while only using gears of the same size: http://507movements.com/mm_226.html

I wonder if anti-virus and anti-malware companies will add this to their black lists.

I was on the list and now I got a Facebook password reset code to my phone, without asking for one. Someone already seems to be trying to use the passwords.
