I been using Ubuntu/Debian for over 5-6 years now but never got an opportunity where i had to check the available version of particular software in repository and know about its dependency and also reverse dependency.
sudo apt-cache showpkg ftp
0.17-19build1 (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_lucid_main_binary-i386_Packages) (/var/lib/dpkg/status)
0.17-19build1 - libc6 (2 2.11) libncurses5 (2 5.6+20071006-3) libreadline6 (2 6.0) netbase (0 (null)) netstd (0 (null))
Well its over month we at Csscorp , my current workplace released a complete beginners guide on the deployment of Openstack for Ubuntu natty.
All the information for the same can be found at http://www.cssoss.wordpress.com
Am lucky to be part of the team where i got my first hand into cloud computing and i can see Openstack a very promising entity, after all its backed by Rackspace and NASA beside over 100 other corporate houses.
Am very happy to say that my talk has been selected for this year`s Desktop Summit in Berlin. I will be talking about “Indian Government Adoption to FOSS.”
The complete list of talks are here https://www.desktopsummit.org/program
I just hope to get Visa on time. 😀
I been traveling across colleges and places in India so from now onwards i will be putting all details and information about it on my blog. I been escaping it for a while.
Its been almost 3 months for me in Chennai and finally i attended LUG-Chennai meet up. Thanks to Srini for giving me lift for the venue as am yet to become familiar will bus routes in Chennai.
Before reaching at venue we got chips, coke and some other snacks for the meetup as we were celebration natty release party. I was very happy to see a gathering of around 40 people at the venue.
There were some other talks as well like government of India spoken-tutorial initiative and a student giving introduction to google`s GO programming language.
Lastly we had a our youngest member took the dias and spoke about natty and its feature with a slide exceeding 150 pages 🙂
I liked the way he demonstrated natty and told others about Unity and other major improvement in the release.
One of the most important thing that happened during the meetup was that we had an uninvited guest a “Monkey”, yes he was in the party too. I offered him some chips and he eat it with fun 😀
Overall i would say although i missed most of the old fellows of Ilug-Chennai as srini was the oldest of the present members there.
I hope to meet them regularly now for the meetup.
All this while since 2008 i was happily using Hardy on my laptop but since the official support is getting over soon i preferred reinstalling from fresh. I was thinking to install 10.10 but today only i came to know that my CD drive is nomore. Thanks to USB boot, i managed to have get Lucid working on my ACER 5920 laptop.
The only place where i was stuck at is the mic was not working after googling i came to know that my Codec: Realtek ALC1200 and solution to that is adding 2 lines in my alsa config file.
$sudo nano /etc/modprobe.d/alsa-base.conf
options snd-hda-intel probe_mask=1
options snd-hda-intel model=auto
Restarting ALSA (sudo alsa force-reload) and also checking alsamixture 2 confirm if mic in muted.
I have never coded in my life so its time to learn and do sumthing !!
In my previous Job where i was supposed to code in Python and i was not quick enough to do that, i came to know about this Virtualenv funda.
We need a virtual environment so that we can install certain Python software which we need for specific application, like Python Django framework which has its on deps and which might break other current apps which uses older version of it.
sudo apt-get install python-virtualenv
Suppose you want to create a directory name “pywrk” and this to work on your python virtual environment simply map this directory to virtualenv
Lets setup virtualenv now for this directory
$ virtualenv ~atul/pythonwrk/
$ source ~atul/pythonwrk/bin/activate
So we have our own python local environment setup. We can install modify add all packages inside this directory and it will be served for our local environment.
After 2 hrs of brain storming on weekend in my office finally got spell checker working for my open office 3.2 on ubuntu 10.04. i had to take expert help from Hobbes, nigleb and lastly Indranil dada and it worked.
sudo apt-get install hunspell myspell-en-us openoffice.org-help-en-us
Once this is installed open a open office document and TOOLS -> OPTIONS –> LANGUAGES
Once this is done check WRITING AIDS and do as screen shot does.
Restart your open-office and you will have spell checker working.
Apart from playing with the Source Code Open Source Software has given us.
Installing Monit :–
sudo apt-get install monit
This command will install Monit on Ubuntu.
In order to Start the Monit we need to edit file “/etc/default/monit” and set the “startup= 1”
This will start the Monit, but we need to do the real work inside the “/etc/monit/monirc” file, and mention what all services we want to be monitored.
I have simply added a script for monitoring my Nginx Server
check process nginx with pidfile /var/run/nginx.pid
start program = “/etc/init.d/nginx start”
stop program = “/etc/init.d/nginx stop”
But before that we need to enable few other services as well like:–
set daemon 20 # check services at 2-minute intervals
set logfile syslog facility log_daemon #for log analysis
set httpd port 2812 and
use address localhost # only accept connection from localhost
allow localhost # allow localhost to connect to the server and
allow admin:monit # require user ‘admin’ with password ‘monit’
# allow @monit # allow users of group ‘monit’ to connect (rw)
# allow @users readonly # allow users of group ‘users’ to connect readonly
Once am done with this i will restart monit and see the status on localhost:2812 , we will see the status saying nginx is running.
let kill or stop Nginx and see the same url, you will see a message saying Nginx is stopped.
As we have asked the monit to check and restart the service at 2 minutes, you will see the process up and running again.
Its been almost over 15 days i left Delhi and moved to Pune 2 work for a startup.
One thing i realized during these days is never compare Delhi with any other City of India.
I remember my days of cribbing autowallas in Delhi, trust me they are better than the ones across India. 😛
So am not going to compare anything now as it always ends up me favoring 4 Delhi.
I miss the food, PVR and crazy bunch of my friends with whom i had most awesome days of my life.
Am sure of making a trip soon in January and spend time all around.
Well i call it curious cos i been just told to upgrade Redmine without giving any other details.
some strange situation :–
$ dpkg -l rails [/php]
gave me nothing (omg my redmine instance running without Rails)
After some googling and #redmine irc channel i figured out like python easy_install and ubuntu/debian ruby uses gem.
So on typing
$ gem list –local
*** LOCAL GEMS ***
Told me these are the magical pkgs allready installed.
I also figured out with help of dpkg -l that i have mod_rails(http://www.modrails.com) and ruby 1.8 installed.
I had to spend some time to figure out what is current version of redmine installed on my server.there was a simple way to find that.
[php] $ elinks http://myredmine/admin/info[/php]
Redmine 0.9.6.stable (MySQL) <– this was my configuration.
Then i followed steps provided at http://www.redmine.org/wiki/redmine/RedmineUpgrade
I took mysql backup and filebkp too along with changing directory location in my virtualhost.
My 1$ Advice, please install additional plugins one by one from the repo which has latest release of it rather upgrading and moving the plugin from older version of Redmine else you will end up going in lot of shit. Most of the older plugin are still not supported in 1.0.X version of Redmine.
