Using tmpfs in /tmp

-
I've been stalling moving /tmp to RAM ever since i first bought a SSD for my computer last year. Now when i finally got the energy i read a bit about it and it was almost too easy. Just add this line to fstab then restart or run mount -a and it should work.

tmpfs /tmp tmpfs defaults,nosuid,size=1024M,mode=1777 0 0

I'm pretty sure the mount options can be better tweaked. Here is an excerpt from the documentation.
tmpfs has three mount options for sizing:
size:      The limit of allocated bytes for this tmpfs instance. The 
default is half of your physical RAM without swap. If you
oversize your tmpfs instances the machine will deadlock
since the OOM handler will not be able to free that memory.
nr_blocks: The same as size, but in blocks of PAGE_CACHE_SIZE.
nr_inodes: The maximum number of inodes for this instance. The default
is half of the number of your physical RAM pages, or (on a
machine with highmem) the number of lowmem RAM pages,
whichever is the lower.

jQuery floating table header plugin

-
A jQuery plugin that makes the header of a table floating if the original header isn't visible due to scrolling. The plugin will automatically choose the thead tag as the header for a table. If thead isn't found it will search for rows marked with the class 'floating'. The behavior can be changed by the settings forceClass and markingClass. News 2012-08-19 This plugin is no longer maintained by me and this page will therefore not be updated anymore. 2011-01-04 1.4.0 ! Lazy loading of tables and performance optimations by Jason Axley 2010-08-02 1.3.0 ! Better ie6 support, http://plugins.jquery.com/node/16655 Fixed parameter name typo, http://plugins.jquery.com/node/16819 2010-07-08 1.2.0 ! Fixed a few bugs and added reinit and recalculate functions to the table. 2009-10-19 1.1.0 ! Better compatibility, better tested. There are still some problems with IE6 that i would like to have some help with. 2009-10-15 1.0.7 is out! With all fixes made...

Seascape - OpenVR adaptation of a 4k intro

-
Image
At Revision this year I competed in the 4k intro competition with an intro called 'falling'. Because I've been doing a lot of VR related stuff lately I decided to convert the intro into an interactive VR experience(?). The original shader is a single raymarched scene which means that demo is very demanding on the GPU. But you can provide a scale factor for the framebuffers on the command line to get acceptable framerate. The binaries are compiled for Windows 10 and can be downloaded here . I suggest putting on some nice background music like  Röyksopp  for maximum effect. If you're not that into VR you can go over to Shadertoy and watch the intro instead,  https://www.shadertoy.com/view/4dcSDN .
