- Matching algorithm

July 22nd, 2014
by leviathan

Hey folks
Since the GPLed dating platform code out there is crappy PHP work and not suited to help geeks meet each other either, I started designing a new matching algorithm in course of the rewrite of as a Ruby application.
Basically the idea is quite easy. First I travel the bipartite tree and cut it into subtrees matching the basic requirement of matching sexual orientation and this way saving CPU power by checking for bidirectional preferences.

Second step: I will then value additional attributes based on a two way connection and average the weight of every forth and back arrow.

For the example on the upper graphics that would mean: R=(((6+1)/2)+((3+4)/2)+0)/3=2.3
Illuminated! ;-)

Another practical example: Let's say I choose under "preferred editor" select that it's absolutely important to me that my partner like vim too, then anyone who likes vim as well will be given 100 additional points when being weighted in our matching algorithm, and so all the vim using geek girls are listed first (followed by the emacs users ;-)).

I'm not quite done yet, but that's where I'm going :-)
Please gimme feedback.

openerp on CentOS-6 (with RPM)

February 8th, 2014
by leviathan

First fit the package depencies like described here:
Somehow the installation prefix of the RPMs from the daily build service( points to /usr/local which is... unhandy
The solution is to overwrite some rpm macros which check for unpacked files...
echo "%__os_install_post %{nil}" >> ~/.rpmmacros
And then installing and rebuilding the srpm with rpmbuild -ba

networkboot, u-boot, tftp

February 3rd, 2014
by leviathan

I'm using the following boot script in order to boot uImage and device tree blob directly from my PC.
No SD card removal, no flashing.
It boots out of RAM immediately
Edit ips and ethernet address accordingly to your network and hardware configuration.

setenv initrd_high 0xffffffff                                                      
setenv fdt_high 0xffffffff
setenv bootargs "root=/dev/mmcblk0p1  rootdelay=10 rw console=ttyS0,115200 panic=10 clk_ignore_unused"
setenv ethaddr D2:91:80:B7:AB:5C
setenv serverip
setenv ipaddr
ext4load mmc 0 0x43000000 boot/script.bin
tftp 0x49000000 sun7i-a20-cubieboard2.dtb
tftp 0x46000000 uImage
bootm 0x46000000 - 0x49000000

KDE Active on Odys Xelio

January 19th, 2014
by leviathan


Hi folks
I've now managed to get plasma-active up and running on the 50$ Allwinner A10 tablet from Aldi...
But it's not fun to use it, since it's already swapping like hell after a short period because of the low memory...
See the htop screeny attached...

linux-next on INet-97F Rev 02

January 12th, 2014
by leviathan

As you might recall from my last post, I was trying to get linux-next running on the INet-97F Rev 02 as it can be found within the Odys Xelio and many other low cost consumer tablets made in China.
I now successfully managed to boot the linux-next uImage with a rudimentary DTB on it.
You can find the commit with the DTS added on my git repository:;a=commit;h=5495b546b3572f001c84a8c74e7547c5cc88d704
Unfortunately mainline doesn't yet contain the sunxi-kms graphics driver since it yet needs to be finally developed and ported forward by Luc Verhaegen.
As soon as his driver patches hit mainline, as well as the ones from Boris Brezillon (for NAND) I will be able to provide fully functional vanilla kernel builds for MER-Project and openSUSE builds.
So stay tuned! ;-)

linx-next on ODYS XELIO (vol.1)

January 11th, 2014
by leviathan

This tablet contains the INet-97F Rev 02 board, which has been supported by fedora arm remix already for a very long time.
Now that I have full access to the hardware it's only a question of time, until I've got together a complete DTS and have it up and running with a vanilla kernel.
