ELV sucks

A friend gave me a link to an ELV product which I copied and pasted into my browsers URL bar. ELV then presented me with this completely useless warning on their webpage:


Additionally they set a shit load of cookies. Obviously one or more of them are used to prevent this retarded warning.

I wonder why should I run an anti-virus program when I access a website? Especially when my browser is running on a Linux box behind an OpenBSD firewall? I’m sorry but I haven’t seens something this retarded ever.

So my recommendation is:

Fuck ELV. Never ever ever ever never ever buy something from ELV!

Also don’t visit their site, block and delete all their cookies.

LZWDecode a PDF File

Today I wanted to dissect a PDF file. Running pdf2ps quickly showed some big lumps of binary data. Looking a bit closer I found out that it is run through the filters ASCII85Decode and LZWDecode. After failing to decode this myself I searched again on the net and found the following blog entry:

Converting a PDF to PS without the LZWDecode filter

So just run the following commands:

qpdf --stream-data=uncompress original.pdf decoded.pdf
pdftops decoded.pdf decoded.ps

Avrdude Prints Part ID

Yesterday I saw the following error message of avrdude a bit too often:

avrdude: Device signature = 0x1e930f
avrdude: Expected signature for ATmega168 is 1E 94 06
Double check chip, or use -F to override this check.

Since I have a random mix of atmega 48, 88 and 168 and even some ‘p’ and ‘pa’ versions I often just try and get the error message. Then I try avrdude with some other part ID and often get more errors.

That’s why I wrote a patch (and log message) for avrdude (trunk @r1298). It just adds the device id to the output after the signature which has been found:

avrdude: Device signature = 0x1e930f (probably m88p)
avrdude: Expected signature for ATmega168 is 1E 94 06
Double check chip, or use -F to override this check.

This looks much better :)

Yes, I could use a microscope to read the part number from the chip but that’s too cumbersome. I prefer a solution where the software is telling me which part it is.

Reset Resolution of X Server after Program Crash

Today I played Warzone 2100. In the second mission in the beta camp I gave orders to build defenses, factories and other things. Then I loaded the transporter and started it to get to the missions map. But then the program crashed and left the X server in a pretty low resolution.

Now how do I reset the resolution?

Easy, the following line does the trick:

xrandr -s 1920x1080

You may have to choose the proper resolution for your monitor. Just entering xrandr without any options shows the available resolutions.
