Tommorow I will be going to Jamshedpur(India) to attend my brother’s wedding, Since Jamshedpur has almost no data for openstreetmap . I am taking  my GPS with me. Hope to do some traces.

On the other news :

1 ) openstreetmap.org home is now available in 4 languages : German, French,Icelandic ,Slovanian and some partial spanish .

Thanks to london hack weekend .Many more have started working on their native languages. However  no Indian languages support till now.

2) JOSM has a good amount of foreign language support, Me and Meejan has started to work on the bengali interface and some work has been done.

3) Potlatch and Openstreetmap wiki translation is also ongoing

If you are interested in seeing Indian languages in these tools , We would be happy to accept your help .Visit here for more details.

4) Arun Ganesh and H.S Rai will be representing OpenStreetMap India in upcoming State of the map 2009 to be  held in Amsterdam(Netherlands) from July.

5) Now osm.org routes to openstreetmap.org as well

Fedora Activity Day@BCREC by dgplug

So finally the Fedora Activity Day which was supposed to be held during Horizon’09 in April was held over two in 14th and 15th May,2009. The reason was that horizon got canceled due to some reason.

Here is a complete jot down of the whole two day experience

Day 1 :

We started a little late.At around 12 noon because of the projector was not working laptops.With  audience size was around 30 we started.

Arindam started by introducing the fedora project to the students. he introduced the Four F’s of the fedora project along with the community as well. He in fact introduce all  bits of the project.

Next was Kishan and Me , we tried to bust most of the misconceptions about linux/fedora in general.

Next we decided to actually give the students a demo of what the busted few minutes ago. Debashree, Amrita, Arpita showed them inkscape and gimp. Rangeen, me and arindam showed them video and music in Fedora.Along with Rangeen showing them KDE 4.2 and it attracted attention. Every machine in the Lab was running FEL live cd since there was no persmission to install Fedora in those machines[:(].

Whole of this continued till 2:10 and we decided to take a break.

After break we continued, this time 15 more students from electronics and communication branch came and joined us.

We introduced IRC to students and gave them a brief demo of it.

Then Rangeen started with FEL. He introduced GNUSim8085 and Ktechlabs which attracted most interest. There was power cut and outside was cloudy, so it was dark. but somehow even with UPS ans trailing machines rangeen continued.After the UPS gave up. We formed small groups of 8-9 and used out 5 laptops to demonstrated FEL. The session went along over 2 hours.It was a comprehensive demonstration and was a good one.

Due to lack of power, we decided to call it a day and gained permission to continued over the next day.

Day 2 :

We started day 2 with Some basic commands by Harsh Verma (a new fedora ambassador from dgplug). He showed them efficiently. Even showed the use of man and info pages. Me and Arindam  helped Harsh with this session. We showed them chmod , file permissions and a word of caution”not to login as root in GUI”.

The next session was vi by Dibyanshu. He gave a very good session on vi and showed most of the cool stuffs. I, personally liked the session very much.This guy is very new to dgplug but is showing great enthusiasm.

We took a break of 20 min and returned . Ratnadeep started with his GCC session. We decided to take on small assignments and started doing them using GCC. Ratnadeep did gave a comphensive demo of GCC and did well. Arindam decided to help them using Anjuta IDE and the same assignments were done using that.

This went till almost 5pm, power went out again. But I took my java session in my laptop. Showed them openjdk, the difference between openjdk and sun jdk. And how to install sun jdk in fedora using alternatives. This went on till 5:45pm and decided to call it a day.

The feedback was good. event though number of audince was less but it showed enthusiasm. Hope to get good contributors from this pack. There will be a post FAD session after the semester exams to keep nurturing this enthusiasm.

Over and all the session was successful and a good one.

With this session we  gained permission to install fedora in a machine. And me and Arindam decided to use this as a local mirror for the labs and students. Need to sort out some techical difficulties though. It currently behaves like a mirror in a box.More on this soon.

My cam’s battery gave up in mid ways so didnt clicked much , anyways pics are here :

Google Summer of Code 2009

Well, like previous year  this year we are also in Google Summer of Code 2009. So if you are interested in OpenStreetMap, This is the right time to do so. You can take a look at potential project applications here.

Not so good :(

Okay, My mac’s keyboard seem to be b0rtked.

If i press these keys ‘4”r”f”v’; I get this : ‘45”rt”fg”bv’

Is this a hardware problem??

install fest @KGEC

On 21st feb , We (/me ,Arindam ,and Ratnadeep ) boarded the 5.40 AM bus to kalyani (for the FAD at Kalyani Goverment Engg.College,Kalyani). However we faced a small political unrest@memari that made us leave the bus and board the next available local train . Finally after changing 3 trains we reached there .Rohit (KGEC) came to pick us up .

On reaching the campus we were amazed to see the crowd waiting to  register their names .We went upstairs to their seminar hall and there were lots of people already there .Indranil Das Gupta was the chief guest,Rangeen was already there along with Sheyank and Mitesh from NIT durgapur (they had taken 50 Fedora 10 dvds with them ).

Indranil Das Gupta started with his introductory speech , and it was well recieved .He talked about mainy things but to sum them up ,it was an introduction to FOSS community for future contributers .During his speech  a lot of teachers were there  who were keenly interested regarding this , I heard that their Electronics HOD was using linux for last 4 years.

Indranil’s  speech lasted till 1 PM and then he left for kolkata . Our talks started after the lunch .

Arindam gave a nice introduction on fedora project.I spoked about myths about linux (with help of fedora). Since most of them were begineers these talks were well recieved .Our session lasted till 4 PM .

After our talks, Rangeen and Ratnadeep took charge of the install fest which lasted till 7 PM .even though they patiently did a informal one till 2 am .

Pics are here and here .

A more detailed blog is here .

Past few days (including mukti09)

Last few days were hectic to me as there was lot of things that was happening around me .

6th Feb : It was Mukti 09 day ,  a national level tech fest on opensource at NIT Durgapur . Me and Arindam had to do a talk cum workshop there .Our Pre Mukti talk was canceled due to bandh and got 3 hr slot , It was scheduled at 5:00 PM .

However we decided to go a little earlier because we along with Indranil Das Gupta and Yu Yu Din were suppose to go and visit Bijra High School .It was at around  12:30 PM when we reached there ,met with Indranil Das Gupta and Yu Yu Din and started for Bijra ,but before we left the campus we called Pradeepto and took him too .At around 1:51 PM Debayan called us up  for setup at fedora stall as they are lacking volunteers but we were already on our way to Bijra .

In Bijra , there were lots of stuff that were happening , Bijra school is getting lot of aids from different section of society and they are utlizing it for a good cause .Both Yu Yu and Pradeepto liked it very much . and lot more things were discussed .

We returned to NIT campus at around 4:30 PM and headed toward IT department where our ” A day with fedora ” were suppose to be done .We started a 30 min  late at around 5:35 PM .Satya came along but she was too tired as she just finished a talk .

There were some 50+ DVD’s that were distributed along with registration kits , I asked Debayan for 15 more DVD’s to distribute in the event just as we were on the start , Nevertheless we started with Arindam’s introductory talk on “Introduction to Fedora” , He had some cool slides where  he showed ” Freedom | Friends | Features | First ” of fedora project .He also showed some cool videos like ‘Truth Happens ‘ , A video showing new features of F10 ,starring stickster and gergdek .Next was my turn , I gave talk on “Myths about Linux ,Busted with fedora ” where i showed basic misconceptions on usage of Linux . A video on ” Why fedora ” by gregdek is shown along with the talk .

Finally we conducted a small workshop on ” How to create bootable live usb for easy use “  . The local mirror of NIT was b0rked and Debayan mailed us regarding that a day before , anyways we continued with as much we can , and finally got 8 machine getting all that we need . Arindam hosted his local FTP server so that people find it easier to download .The workshop went alone and was quite successful .We faced a lot of questions , a guy from NIT agartala said the workshop was useful as  he can now got a solution to their connectivity problems . Finally we ended with the “Choice” video .

We had dinner there and finally returned home at around midnight .

7th Feb : Me along with Arindam ,Indranil Das Gupta and Yu Yu Din boarded the 6:14 AM train and went to Kolkata where IDG had to give talk . We went to IDG’s office and waited and finally went to Science City where talks were held . M Arulraj gave a talk on Open GIS . IDG gave his talk , I don’t remember the tittle of talk though . and one talk was on FOSS in bio informatics by Mr. Sudip Kundu .

Finally we all went to kafuluk at china town and had our lunch cum dinner there ./me and Arindam went to my house at sontosepur .

8th Feb : Woke up early and came back to Durgapur by taking 7:30 AM bus . It was “brigade cholo ” day , the bus we took was the last bus available as most buses were hijacked to bring in people . Reached Durgapur at around 10:30 AM and went back to NIT Durgapur at around 12 noon , On way to IDG’s talk ,we went where stalls were hosted , apart from Dominos and CCD rest were empty .IDG’s talk on “Indian FOSS Community was superb ” and at it was the last talk of mukti 09 .

NIT Lug guys did a superb organizational effort to bring up such a event and overall it was awesome to see so much participation .

Fedora on mac ..rocks

It has been two months since i bought my macbook .I mostly use my desktop for daily work and mac OSX was serving me well . However due to need i started setting fedora on my mac . Arindam did that previously and his fedora installation was fine .

After installation , i found that apart from common issues like wifi and touchpad , sound was missing as well .

So decided on a google search ,which reaveled some post from forums . I tried them and everythings is working good .

Here is a small compilation of those methods .

1. Wifi and sound

these four are needed

kmod-ndiswrapper-1.52-30.lvn9.i686.rpm
kmod-ndiswrapper-2.6.25-14.fc9.i686-1.52-30.lvn9.i686.rpm
ndiswrapper-1.52-1.lvn9.i386.rpm
R151517.EXE

P.S : Well , rpmfusion.org is finally here and all these packages are transferred to rpmfusion.org . Please use

yum install rpmfusion-free-release rpmfusion-nonfree-release

and search for above packages . Plus with rpmfusion its better for updating .

Thanks to Thorsten for pointing me out .

now

mkdir wifidriver
unzip -a R151517.EXE -d wifidriver/
cd wifidriver/DRIVER/
su
# install ndiswrapper and the wifi driver
rpm -Uhv *ndiswrapper*rpm && rm -i *ndiswrapper*rpm
/sbin/modprobe ndiswrapper
ndiswrapper -i bcmwl5.inf && rm -rf wifidriver && rm -i R151517.EXE
echo "options snd_hda_intel model=mbp3" >> /etc/modprobe.d/soundcard
echo "blacklist bcm43xx" >> /etc/modprobe.d/blacklist
echo "blacklist ssb" >> /etc/modprobe.d/blacklist
echo "blacklist b43" >> /etc/modprobe.d/blacklist
# ndiswrapper is used for wlan0
echo "modprobe ndiswrapper" >> /etc/rc.d/rc.local
echo "alias wlan0 ndiswrapper" >> /etc/modprobe.d/ndiswrapper
/sbin/service NetworkManager restart

and reboot the mac .

Pommed helps in  controling the LED and keyboard backlight, soundcard, infrared remote and more. :

wget http://downloads.diffingo.com/diffingo-repo/diffingo.repo -O \
/etc/yum.repos.d/diffingo.repo
yum install pommed

pommed starts as a startup service .

For touchpad its synaptic that comes to the rescue .

The xorg.conf as of my machine is here :xorgconf




However after an update to 2.6.26-6 kernel , and subsequent update of ndiswrapper , even though wireless was working ,my sound got muted in kde  which was fixed soon .
And on KDE4, a red light appears from the headphone jack . It indicates that digital audio got enabled instead of analog .This happens if IEC958 module gets enabled . So sometimes it ignores a headphone plugged it .
It can be switched off by :

 volume control > switches > IEC958 (dechecked ) . 

or It can be reset with a toothpick though if it remains on even while using mac osx ,better to do a google search for this or post in a mac forum 
Enjoying my mac :p
