Online Programming-Related Game Recommendation: "Untrusted"

Hi all,

someone on ##programming on Freenode introduced me to this game called
“Untrusted” - . It requires writing
some code in JavaScript to overcome the challenges there, and I found it to be
a fun game.

It naturally requires to enable and/or whitelist JavaScript on the page.

My windows desktop, which syncs its time off of an ntp daemon on a linux
system, the clock on my asterisk system (which syncs its time off of its
own ntp daemon from a different ISP), my Nokia X1 candy bar phone (syncs
from Golan 2g via cellcom) and my Google Nexus 4, which syncs from Golan
3g, all have the same time.

I think the update was included in KitKat, not anything older. The
android phones run the UNIX standard, a UTC clock and display according
to a time zone file.

geolocation in firefox

Hello Everyone

I changed enable.geolocation to false in firefox, but it still doesn't work with the site that I want to enter. I am still redirected to israeli site instead of the abroad site.

Anyone knows why this configuration doesn't work? Is there another way to make it work? I tried the extension of geolocater but this one also doesn't work for new firefox versions

strange mac address issue

i have an embbeded linux board. connected a usb2eth (rj45), and through that to the lan.

suprisingly, another usb2eth on another copy of the embedded board, has the same mac address, and so i get conflicts on the network.

swapping different modules of usb2eth on the same board gives same mac address.
I'll call this mac address 'Mac Address A'

so i wanted to see if linux is causing this issue. i tried to connect these usb2eth on a win7 machine.

on win7, all of the usb2eth get the same mac address. however this is a differnet mac address then the previous. i'll call it 'Mac Address B'

on another usb port on the same win7, i get 'Mac Address C'. again it does not matter which usb2eth i use

All the usb2eth are idVendor=0fe6, idProduct=9700 (dm9601)
(although physically different)

any idea ?

LaTeX on Ubuntu


Any LaTeX/Ubuntu users here? I have a stupid problem that I have spent way too much time researching, and all I see is that years ago there was at least one related bug open
that was never resolved, apparently because people found workarounds in situations much simpler than mine, and the maintainers didn't bother.

I have a bunch of fairly sophisticated LaTeX documents
that use quite a few things that come from texlive. They are built through latexmk, everything works perfectly fine on Red Hat systems, including CentOS and Fedora.

I have a target build platform that is

buntu 12.04.1 LTS (GNU/Linux 3.2.0-29-generic x86_64)

Everything needed is installed (the various texlive packages, latexmk, all that it uses
, etc.). It will become obvious in a few moments what makes me so sure.

What does not work is that no cls or sty files are found. The first thing that throws an error is

! LaTeX Error: File `article.cls' not found.

(obviously, triggered by \documentclass{article}). Yes, the file exists in the expected place. The fact that it is not found without extra effort means that something is seriously wrong. If I add the directory where article.cls lives the same error is through by the first \usepackage{} statement, etc.

Oh, kpsewhich and kpsewhere do not find article.cls or anything else.

Obviously, I ran (as root/sudo) texhash, mktexlsr, update-texmf, and everything else I could think of. They all run fine. E.g., texhash creates ls-R, ls-R-TEXLIVE, ls-R-TEXMFMAIN, etc. under /var/lib/texmf, update-texmf regenerates /etc/texmf.cnf, and so on. No relief.

I purged and reinstalled texlive - nothing helped.

I got desperate and ran

$ export TEXINPUTS=$(ls -R /usr/share/tex* | awk '/^\/.+:$/ {printf "%s",$0}').

(including the final dot - for some reason pdflatex did not find files in the working directory, either). If you don't follow, this adds every single TeX package directory under /usr/share to the TEXINPUTS environment variable, which is the path where LaTeX looks for anything it needs.

After this, everything worked.

May I vent now? IT IS NOT SUPPOSED TO WORK LIKE THIS!!! Pheewww...

I should not need to put every bloody package directory into my TEXINPUTS. There has got to be a better way.

Lots of Google hits on Ubuntu forums with complaints about similar problems, but no solution (at least none that worked for me).

Has anyone here encountered this problem? Solved it? Any ideas?

The FSF Announces New Versions of the GPL.

The Free Software Foundation (FSF) has decided to contribute to
the noble cause of the free and open source software’s licences
proliferation ( )
and following their popular announcement of version 3 of the
GNU General Public License, or the GPL for short, which is incompatible
with its version 2, they have now announced even
more versions of that popular licence:

Which GPL will free and open source software (FOSS) developers choose?

[HAIFUX LECTURE] Linux Containers and the future cloud (part II) -- Rami Rosen

On Monday, March 31st at 18:30, Haifux will gather to hear a talk by 
Rami Rosen:

    Linux Containers and the future cloud (part II)

If you missed part I, please refresh your memory on the "Resource 
Management in Linux" lecture, given in Haifux in May 2013 (see:, audio recording available). Much of 
part I was dedicated to this.


Lightweight process virtualization is a virtualization technology which 
exists for many years, in Linux and in other OSs, and which matured 
significantly in the recent year. Linux-based containers are based on 
this technology. In this lecture, I will discuss the Linux kernel 
infrastructure for Linux-based containers as well as several interesting 
userspace projects which use this technology.

Following is a list of the main topics which will be discussed:

* Namespaces and Cgroups - the building blocks of containers.
* A Short survery of Linux container projects (open source and proprietary).
   * The LXC project:
   * LXC containers
   * LXC management
* Docker - the Open Source containers engine project.
* CRIU (Chekpoint/Restore in userspace)

and more.

We meet in Taub building, room 6. For instructions see:

Attendance is free, and you are all invited!

Future lectures:

There are no scheduled lectures.


We are always interested in hearing your talks and ideas. If you wish to 
give a talk, hold a discussion, or just plan some event haifux might be 
interested in, please contact us at webmaster@...
