I wouldn't say the spinning in a rotovap is particularly related to this question. The spinning is just to make sure the substance is being heated evenly by the bath of hot water/oil - the evaporation happens because the thing is put under a partial vacuum.

Did some digging, an apparently, reading from a CUDA-related file in /dev kills everything

hm, this is interesting. My NAMD computational jobs on our math server have been hanging and dying the moment they're started, taking out the terminal with them.

Let's answer them all with "pls"
May 9, 2016 17:37
but now it's mostly known as what people do after donning balaclavas so that they can steal folders from your desk
May 9, 2016 17:36
yeah, "hacking" traditionally referred to the general process of inventing and making things work
May 9, 2016 14:19
whoa, man
May 9, 2016 14:19
it actually moves half of each bit into another bit
May 9, 2016 14:18
what if we made rot 13.5 encryption
May 3, 2016 14:43
no viruses :)
May 3, 2016 14:43
oooh, idea: make it for OSX only

gotta run in a minute
May 3, 2016 14:41
but then packet loss would break everything
May 3, 2016 14:41
a weird scheme might be to authenticate the contents of the last X packets with a single transmitted hash
May 3, 2016 14:40
the question is, how tough does it need to be to break?
May 3, 2016 14:39
You could take only part of the hash, possibly
May 3, 2016 14:34
can't quite remember thato ne
May 3, 2016 14:34
malleable encryption?
May 3, 2016 14:34
don't accept anything with a lower number than what you've already seen
May 3, 2016 14:34
digital signatures that factored in the frame number would also work
May 3, 2016 14:34
but I think your challenge system would avoid that?
May 3, 2016 14:33
one issue is replay attacks
May 3, 2016 14:31
and I'm not sure how expensive that would be computationally
May 3, 2016 14:31
Could you use digital signatures instead? The overhead might get ridiculous if the packets are small, though
May 3, 2016 14:29
asymmetric crypto would provide authentication; I think symmetric crypto would also work, as long as you can securely share a secret first
May 3, 2016 14:28
hmm
May 3, 2016 14:27
if you don't have a cleartext counter, then you'll run into issues if (and when) packets are lost
May 3, 2016 14:26
I don't think the spec includes one
May 3, 2016 14:25
Do the UDP packets still have cleartext frame numbers?
May 3, 2016 14:22
between client/server or something?
May 3, 2016 14:22
What data are you encrypting?
May 3, 2016 14:20
50% is way more than 0%
May 3, 2016 14:20
you don't have to be perfect
May 3, 2016 14:19
oh hush
May 3, 2016 14:19
unbreakable encryption + easily compressed output
