WHAT.THE.ACTUAL.####

underlying hypernova
Nothing fits the angriness, rage, and sadness.
Everything just explodes with no before nor after.
All the walls break, little perks in the wind.
A never ending unfolding sound of broken glass,
everlasting high pitched pink pain.
Sure there can’t be more out of hundred millions electron-volts,
sempiternal ill witched red rain.

Is there a prime number whose binary representation looks like a giraffe?
Yes!
like another prime number?
Yes!
like a prime number of giraffes?
YES!
like Squidward Tentacles?
Heck Yeah!
You’ve probably understood the mechanism by now. Converting a binary image into a number, its nearest upper prime generally only differ in the lesser significant bits, hence most of the image pattern stays the same. So finding a prime number whose binary representation looks like a specific image is relatively easy. I say relatively, because in a computer sens it is quite really complex.
I just wrote a program to do just that. It is written in C and uses GMP. It is around 1k SLOC. It could probably have been much shorter, and even less so in another language. But I wanted something that went a little further than just of simple proof of concept.
I must admit, it’s pretty useless. But still there it is. And there is still much room for improvement. So patches are welcome on GitHub.

Live from Intel’s HQ
I’m going to ditch this core i7 for a m68k or 6502. Who needs a MMU anyway?
Disable XF86Back/Forward
Real ThinkPad keyboards (not this monstruous ignominy) have directly accessible keys for XF86Back and XF86Forward. That is really problematic with web browsers such as Firefox or Chromium since pressing those keys transparently go back or forward into your history, discarding anything you were typing in the process, including that 3 hours long bug report you were just about to submit. That’s rather annoying, to say the least.
Some other blog post suggest to simply disable them with xmodmap. That is in ~/.xmodmaprc (or whatever it is you use):
keycode 166 = NoSymbol keycode 167 = NoSymbol
I personally prefer to remap them to Next/Prior keys. Having these near the navigation keys might come up handy:
keycode 166 = Next keycode 167 = Prior
That’s on Linux though, on FreeBSD the keycodes are 233 and 234:
keycode 233 = Next keycode 234 = Prior
Anyway use the xev command and xmodmap -pke to find the keycodes and remap them to any other interesting key symbol.
Intel’s big bug
That’s pretty hot fucking big deal.
If you don’t mind my saying so.
