On the temperature

I don’t like it. The temperature at 8:00AM in the morning was -27°C.

Cool. But not for my car. It did not start. Even with a booster. The battery is definetly dead.

It started at last after a battery was charged for a half an hour.

“Cover open” and “Pause” problem with Epson Stylus Color 1520

After some time Epson Stylus Color 1520 in our bureau started to fail. The printout is either staggered or fails and LEDs for “Cover Open” and “Pause” starts to flash. User’s manual says “The print heads were moved by hand”.

Maybe. Or maybe no. Actually, no. Read the rest of this entry »

Wire size calculations ;)

Q: Given a single 0,35mm² copper wire, how much current it will handle?
A: ~60A

Stupid me. Used DIY regulated transformes to start my Alfa Romeo today and hooked on the wrong connector. Alfa started. The insulation on the wire made a blue smoke, but … still working 😉

Anyway, got 6mm² wire for replacement.
It’s time to replace car battery too, i think. Or check the generator.

Stuck with apt in Debian?

So so …

W: GPG error: [your favourite mirror here] Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 010908312D230C5F
W: You may want to run apt-get update to correct these problems

Ever met this is last days?
The solution is simple, but not well documented well:
you must add these keys manually (as root or using sudo):

gpg --recv-keys 07DC563D1F41B907 && gpg --export 07DC563D1F41B907 | sudo apt-key add -
gpg --recv-keys 010908312D230C5F && gpg --export 010908312D230C5F | sudo apt-key add -

or in the case you do no use GnuPG

wget -O - | sudo apt-key add -

That’s all.
