I hate this penguin movie

This isn’t the “March of the Penguins”! If I had to watch this on a long-haul flight, I’d lock myself in the lavatory and cry.

The top is a screenshot of a document from work outlining different chassis sizes and their byte value to set for programming. I thought it was a joke because engineers have the weirdest joke. The bottom is a picture of an actual pizza box computer. And it’s running Linux. *shudders* I’m not surprised though. Needs moar bell peppers.

Crypto++ and Linux

This week I’ve re-acquainted myself with Linux at work in order to port an app from Windows to Linux. Besides the aggravation of setting up the OS, IDE, and workflow, I had to use a 3rd party library called Crypto++. Well, it wasn’t obvious to set up or figure out so I’d put this out there in case someone has the same problem.

Basically I was able to include the files, but I got a linker error despite including the files in the project file in Qt. This is the error:

g++ -o encrypter -L/usr/lib -Lcryptopp -lcrypto++ -lQtGui -lQtCore -lpthread
encrypter.o: In function `CryptoPP::AllocatorWithCleanup::allocate(unsigned int, void const*)':

The proper way to include crypto++ is NOT to download it from the website. Use terminal to get the library:

sudo apt-get install libcrypto++8 libcrypto++8-dbg libcrypto++-dev

Then check if installed on system:

apt-cache pkgnames | grep -i crypto++

Which should result with:


If the information above is different (which is possible if it becomes out of date), check the Crypto++ Linux wiki for instructions.

Now add the library to project with the following linkage (written as a makefile macro, but just put the -L and -I parts in the command line if you’re compiling manually):

LIBS += -L/usr/lib/crypto++ -lcrypto++
INCS += -I/usr/include/crypto++

While is is rather specific, someone out there is probably searching for this so here ya go!

If Linux was a car

Really? But your car still runs with Windows

Linux enthusiasts are scary

Shameless cross-post from my car blog:


If Linux was a car, you’d have to build it from scratch just to go to the store to buy some milk. You’d start by compiling an engine and put it on a chassis. That’s fine and dandy and it’ll get you where you need to guy, but it sure is a pain in the ass to turn with a socket wrench on the rack and pinion. So let’s put in a steering column and steering wheel.

It’s not very comfortable so let’s add some seats. Now you realize there are different flavors of seats. Bench, bucket, velour, cloth, leather, etc. Bench sounds nice which is great for cuddling with a significant other! Oh wait, you use Linux. Scratch that, let’s go with buckets for the sportier feel.

Great, but it’s not that great looking. It needs a body. Those damn Apple cars look so sleek and sexy with their glossy exterior, but we all know you can’t modify them. Fk the sheeple and their pretty cars. Those Windows cars actually look pretty good now unlike a few years ago when the Fisher Price Cozy Coup called them out on plagiarism. What can I do with the Linux car? Well, there’s not much to choose from out of the box. Fkr looks cartoony. Meh, fk it, let’s roll.

It drives just as well as the Apple car because they’re almost identical under the hood. You’re feeling pretty smug because you built your own car for free. Well, let’s keep adding mods. You want lib-vtec-honda, but it won’t work in your car. You hack it to work instead. You’re somewhat successful, but you needed another obscure library to get it to work: lib-jdm-bolts. Ok, it works fine, but not perfect.

Oh no, the radio stopped working! Ok, don’t panic, just use another antenna. Crap, it’s not compatible with Linux and you just paid out the butt for it. To the Googles! So many people have the same issue, but with different hardware. WTF?! Grrrr! Ok, this guy says to download ndis-radio-wifi-2.6.1 and compile it for my specific car. Ok. Fk! I need another obscure library: lib-am-fm-cassette. Don’t I already have that?! Jebus H. Chrysler this is retarded.

Wheee, got the radio working. Let’s roll. Going to Taco Bell for some chalupas and Baja Blast. Oh muffin fudger, it doesn’t have a fkn cupholder. Google it. Cupholders aren’t available to Linux due to it being proprietary technology developed by Adobe?! GD it to hell! You end up burning the car and buying a Windows car.
