Could you imagine a guy who takes A4 paper with encrypted text using modern algorithms and decrypts it in 20 minutes which pen and his mind?

Here's a life hack for you.

If you're ever in need of a whiteboard for drawing/sketching, grab a few white a4 paper sheets, a roll of transparent duct tape, tape both sheets together side-by-side. Cover both sheets with tape

et voila! You have yourself a portable & foldable whiteboard!
The more sheets you involve, the bigger the whiteboard will be :)

P.S. It's very handy!!

Printers come straight from hell!

I visited my grandma. She told me that she has a problem with her printer. I printed something (b/w) and looked at it. It looked really bad. The printer showed an error message saying that there's a problem with the color cartridge. I took it out, put it back in and printed again. It looked perfect. But the message appeared again.
Every time my grandma wants print or copy something (even in black and white) she needs to take out this cartridge, put it back in and pray.

One time I printed something with my paper. I have the right paper for it (A4). The printer scaled it down...
IT PRINTED A VERSION FOR ANTS!
It took several attempts and wasted paper and ink but FINALLY it came out nearly perfect.

Printers are the worst devices I've ever worked with.

Update & Thoughts of AngelHack10 Abu Dhabi.
The judges were so non technical they were impressed by an app demo (not ours) that could recognize objects printed in black and white on an A4 paper. The app claimed to read the 3d shape of a device and calculate the running cost based on its power consumption.
I think hackathons must have two pitches one technical and one business. Else every one with hardcoded demos can fool the judges easily.

Every university in the world should have an A4 paper on the front of the main entrance door with big bolded text that says

"DISCLAIMER: HAVING A DEGREE IS NEVER GOING TO GUARANTEE YOU A JOB"

I really look forward to getting rid of end user and front end crap!

Just wasted 3 hours because of a bug report of a client stating, that "the printouts always have a useless empty page after the desired content".
Well, yeah. There actually is content on the site that's meant to be printed.
After 3 hours of fine-tuning and debugging I found out, that the content is in A4 (European default paper format: 210x297mm) and the customer tried printing in some weird ~219.9x279.4mm format. Apparently that's the US 8x11" letter format.
