warlordfffA dot in the map
I don't ever remembering suggesting a site but to be honest I rarely fall into sites that not many people know and worth mentioning, also most of the times I do, I am a bit bored on blog about it so I eventually never do ;-)
Today though it's different, I am taking a break from a presentation it was supposed to be ready...Well...Yesterday, but I am still looking for the right kittens photos to complete this presentation(...don't ask...). Anyway normally I would just watch a movie or something but I am a bit in a mood to blog and latelly I had too much on my plate and had no time to do it, so here I am.
Anyway a friend of mine, Efstathios Chatzikyriakidis had this briliant and simple idea, to make a map where people around the world would state their possition in the map and the OS they use. Some of you might find this useless but I find interesting the fact that I could see the preferance of people around me on what Open Source or Free Software they use and some of you might too. The site is called OSHACKERS and it is licenced under the GNU GPLv3 and if you are curious I would suggest to give it a look and why no register...

Join The G(r)EEKOS Release Parties!!!
The openSUSE 12.1 distribution is released. After 8 months of hard work by the openSUSE community, the result could be something less than awesome. It is true that openSUSE 12.1 has received the best reviews of all famous open source sites and also has begun to gain many new members at the community, users and contributors.
Time to celebrate!
As is known the openSUSE community after the hard work done to release another great distribution, wants to celebrate it! And why not! Around the world communities, Linux groups and LUGs organize release parties.
The G(r)eekos Way!!!
openSUSE 12.1 is already installed on our machines by November 16. The Greek openSUSE community in collaboration with other communities, university Linux teams and LUGs invites you to come and celebrate the brand new release of openSUSE 12.1. Release parties are organized in many Greek cities! If you're near a city where a party is organized do not hesitate to meet us, attend an Install Fest or a presentation about openSUSE 12.1, drink lots of beers, talk with us and have fun!
We expect to meet you at one of the parties, as well as help you organize one in your town! Good company, beer and goodwill are the key ingredients of a successful Release party!
On Thursday 1 December we will celebrate in Larisa with a presentation and an Install Fest at 13:00 and afterward we will go at a local tsipouradiko. Moreover, on Saturday 3 December in Kastoria at 19:00 at Zaza bar. Furthermore, on Sunday 4 December we will celebrate in Thesaloniki at Bar Pierrot Le Fou at 22:00. Last but not least there will be 3 more parties that are going to be announcend the next few days.

On the road again: MYGOSSCON 2011
Going on the road again... after a year of life's transitions and pursuing other interests, I am privileged to have the opportunity to speak at MYGOSSCON 2011 next week.
The title of my paper is "Key Trends: Challenges, Opportunities and Leverage for Linux/OSS Ecosystem". I look forward to the discussions it will generate. :)
Personally, I am looking forward to this with excitement as I have been granted the latitude in content creation. I will be approaching the topic from another angle and with, what I hope to be, a fresh perspective.

SOCKS proxy over SSH
Here goes a quick and valuable tip people don't usually know, or at least a couple of friends of mine were not aware of. The two keywords will be SOCKS and SSH.
Connecting over to a remote server, one can bypass unauthorized access blocked by usually our network firewall. The most common examples given are restricted access to Facebook, MSN or torrents. We can also have unlimited access to all kinds of contents thanks to the nice sysadmin managing the network who puts no barriers whatsoever, but we may not trust him or the network users to permit unencrypted data flowing openly. Having some way to establish an encrypted connection to a known network who we trust, or distrust less, and tunneling over it would be safer. This is where SOCKS and SSH can be much of helpful!
SOCKS is an Internet protocol that routes network packets between a client and server through a proxy server. -- via WikipediaI'm certain as most, if not all, of our daily applications implement themselves some way of proxying (mostly HTTP, HTTPS and SOCKS) or use the system-wide configured network proxy server. Now all we need is a remote and secure server to proxy and tunnel. This is the part where SSH enters:
Secure Shell (SSH) is a network protocol for secure data communication, remote shell services or command execution and other secure network services between two networked computers that it connects via a secure channel over an insecure network: a server and a client (running SSH server and SSH client programs, respectively). -- via Wikipedia
What this means is if we have a SSH-enabled server we can take advantage of it because typically no further configurations or tweaks are needed. Let's take a look at the SSH client manual:
-D [bind_address:]portSpecifies a local ``dynamic'' application-level port forwarding. This works by allocat-ing a socket to listen to port on the local side, optionally bound to the specifiedbind_address. Whenever a connection is made to this port, the connection is forwardedover the secure channel, and the application protocol is then used to determine where toconnect to from the remote machine. Currently the SOCKS4 and SOCKS5 protocols are sup-ported, and ssh will act as a SOCKS server. Only root can forward privileged ports.Dynamic port forwardings can also be specified in the configuration file.
Got it? Great! Let's combine SSH+SOCKS:
I will not provide the details of what each option features - run 'man ssh' and find by yourself. The result is a SOCKS proxy over SSH. Now let's wrap it in a bash script:ssh -C2qTnN -D <PORT> <USER>@<IP>
#!/bin/bash
if [[ `uname` == 'Darwin' ]]; then
trap " {
echo \"Setting SOCKS proxy down...\" ; \
networksetup -setsocksfirewallproxystate ethernet off ;
networksetup -setsocksfirewallproxystate wi-fi off;
exit 1;
}" ERR INT TERM EXIT
networksetup -setsocksfirewallproxystate ethernet on
networksetup -setsocksfirewallproxystate wi-fi on
fi
ssh -C2qTnN -D 9999 <USER>@<IP>
Replace <USER>@<IP> by your username and IP address. This bash script, in case you are a Mac user, will automatically turn SOCKS on upon execution and turn it off when shutting down (Mac users using an OS X version prior to Lion should replace "wi-fi" by "airport"). Other Unix users (Linux, BSD, etc) should set SOCKS host as "localhost" and SOCKS port "9999" in either your system network configurations or in each application you want to tunnel over.

My openSUSE 12 Journal - 3: Lotus Notes 8.5.3
Lotus Notes is what I use at work and the latest v8.5.3 works well on openSUSE 11.4. Although it installed without a hitch on 12.1, things goes awry when I start using it. Here are my observations and how I managed to get it working again. :)
For starters, Lotus Notes 8.5.3 only managed to render about half of its interface. For example, I could see my inbox but email preview pane is blank. Integrated SameTime worked but workspaces and replication tabs were blank too. I suspect it could be some incompatibility or confusion with the GTK libs and I was right... Google is my friend and I discovered a brilliant soul who had the same challenge, created a bug report against openSUSE and even created a workaround/fix.
[Update on 27 Nov 2011]: Oops, it occurred to me that Lotus Notes 8.5.3 is actually 32-bit running on 64-bit openSUSE 12.1. That means the RPM created by Stefan Lijewski should have worked. I cannot recall why I came to the previous conclusion. I have just tried the 32-bit RPM and it worked for me. Therefore, I am correcting my entry below.
Unfortunately for me, I could not use his nicely packaged RPM and online repository because I am using 64-bit openSUSE 12.1.
The easy way is to use a 1-click install via Stefan Lijewski's online repository.
The easy but manual way is to download the RPM before you manually execute a zypper in lotus-notes-gnome3-1-1.1.i586.rpm
In both cases, you will need to verify that your Lotus Notes launch icon has been updated to use the new notes-wrapper script instead of the original notes script in /opt/ibm/lotus/notes/ directory.
Finally, the hard way (if you're so inclined to experience compiling your own code) is the original method I used below.
Below is how I got Lotus Notes 8.5.3 working on openSUSE 12.1 (64-bit).
1. Download the workaround fix from https://github.com/sgh/lotus-notes_gtk2.23.3/downloads
2. Un-tar the fix, tar zxvf sgh-lotus-notes_gtk2.23.3-2028e8e.tar.gz
3. You will need to install additional packages before you can compile the fix. As root, zypper in make gcc gtk2-devel glibc-devel-32bit gcc-32bit
4. In the sgh-lotus-notes_gtk2.23.3-2028e8e subdirectory, compile the fix with make
5. If make completed with success, you should have a new file libnotesgtkfix.so in the directory. Copy it and notes-wrapper to installed Lotus Notes directory /opt/ibm/lotus/notes/.
6. Last and final step, edit your Lotus Notes icons (kmenuedit if using KDE4) and change the default launch script to execute notes-wrapper instead.
That's it. Lotus Notes 8.5.3 should function normally... and its all good for the last 3 days for me.
I hear this would not be a challenge with the newer Lotus Notes 8.5.4 (yet to be officially released). We shall see when we get there. :)

openSUSE ARM Update 25Nov2011
Sorry that no news has been dished out with regards to the openSUSE ARM porting effort, but that’s mostly because things have been busy (honest!)
For starters we have now successfully built around 3500 packages out of a total of about 4700 for the full openSUSE ditribution. So we are well on our way. It hasn’t been easy going though, and we still have lots of hurdles, hoops and obstacles to overcome.

openSUSE 12.1 gets positive review on LAS
Nice and positive review of openSUSE 12.1 on the Linux Action Show on 20th Nov 2011. The YouTube video is embedded below... you may fast-forward to 30:10 where they finally got down to the review of openSUSE 12.1.
Most interesting (the best) comment on that YouTube page was from Jos Poortvliet (our openSUSE Community Manager), "VERY nice review guys! Fun to see how opinions on openSUSE have changed in the last year - from 'meh, yeah, is that distro still alive?' to the awesomeness now :D
As with most things in life, its all about perception and goodwill. openSUSE 12.1 is polished and enjoyable but a number of the great features mentioned, including SUSE Studio and openSUSE Build Service, have been around for a while... anyway, I'm just happy & enjoying the goodwill towards openSUSE. :)

If you ever wanna talk about it with me - I'd be happy to be on the show..."
