The experience at Citrix was great mostly because of the kind of work and guidance i was given, we arrived in Bangalore on 3rd Jan, it was weird that no accommodation was provided to us for the initial weeks, but since manipal is one night journey away from bangalore, we came here after our exams and searched for a flat, we finally decided on a flat in Cambridge Layout (near Indiarnagar) since it was pretty close to our work place which was near brigade road !! I was working with the NetScaler Tools team on a internal stress testing tool called BlackWidow, the best thing about my work at citrix was that i had to work with FreeBSD kernel, which meant i had to use *NIX development tools (cscope/vim/kgdb which is what i am pretty comfortable with) and not some bloated IDE (for me Vim + cscope > any IDE) which i had to learn for my last internship at microsoft, this helped me get started pretty quickly which surprised my mentor, although i was not assigned the feature i wanted to implement still my work was pretty interesting.

I found Citrix to be a really awesome company to work at, it has a lot of interesting products, the people are friendly and helpful and the work culture is great, ohh and not to forget the facilities they provide to employees, but one thing that I noticed during my internship is that the work can become monotonous, so you really need to pitch in and get some interesting work or one might end up doing similar work again and again, but then i think thats the case with most of the places.

The main motive behind me coming to bangalore was meeting interesting people, not that people in Manipal were less interesting, i wanted to meet with some ‘similar’ minded people. I had hardly talked to other people from my college who interned with me, but they turned out be interesting, also interns from other colleges like PeeShit (read PESIT) were interesting. I didnt actually went out to meet people, but then i guess i can do that now as i am going to stay in bangalore. A few days back i met folks at Artoo on their Demo Day, they are doing some really interesting work.

My internship is over but I will be staying in Bangalore for my first full time job, i have a few on campus and off campus offers but more on that some time later, Thanks to my flat mates Mikhail Jacob, Sohil Himanish and Tushar Dadlani for making my stay in Bangalore awesome and Thanks to my mentor, manager, all fellow interns and everyone else at citrix for making my work awesome, you people rock !!

Here is a video of the android phone (Samsung I5800 Galaxy 3) being used to control a car racing game.

And now the working

After this we decided to work on something which i wanted to finish a long time ago (remember Weekend Project I) so we finished Weekend Project III which is well Weekend Project I + Weekend Project II

And the working of Weekend Project III

Weekend Project III Data Flow

The Data Flow is Phone —-WiFi—-> PC —-USB—-> USB to RS232 Converter —-UART—-> MicroControler —-Relays—-> Toy Car Remote —-RF—-> Toy Car, which is almost same as that of Weekend Project I, except for processing of Sensor Data on Phone.

PS – if you were not able to look at the video’s above they can be found here, here, here and here, also Game On won 2nd prize in Mobi Vision – a mobile application development competition

MobiVision in TextTatva and i dont exactly look like that cartoon depicting me !!

file: fsm.h contains the function definition for our FSM

file: fsm.c contains the function implementation for our FSM

file: main.c contains an example on how this FSM can be used

PS – If you are reading this post on a blog aggregator like planet you can view full post here

the concept is simple, i send commands through my phone over wifi to my laptop which controls the car remote, controlling a toy car remote is very easy with a Parallel port and few transistors but laptops don’t have parallel ports, so i used a micro-controller in between to sort that out, so now micro controller controls the car remote by acting on signals received over UART from laptop.
the working is Phone —(WiFi)—>Laptop —(USB/UART)—> Micro controller —(Relays)—> Car Remote —(RF)—> Toy Car
will post details with code sometime later

i asked DJ if he wants to join me and after few weeks of coding there it was Manipal university’s first (working) Feedback System, when the point of hosting it came, i was surprised to find Manipal University has no Linux servers, i mean come on no Linux what are you people click sys admins, then we decided to setup our own server in the department, thus giving Manipal university its first Linux ( fedora 10 ) server.

currently it just hosts the Feedback System, but we are planning to use it as local ( internal ) fedora repository mirror, we need permission from the WiFi provider ION because almost all the students use only WiFi and not LAN, last time we tried we were denied by saying ” You are a threat to our network “, lets see how it goes this time. we will also require people to manage it but i think this can be handled very well by LUG Manipal, some pics

Fedora 10 server in Manipal

Fedora 10 server in Manipal

PS – i am looking for a way to convince them that setting up a mirror will be helpful for them as well as students can anyone suggest me how to go about it??

export http_proxy=http://127.0.0.1:5865

Ok coming to the main point, go and download http://sourceforge.net/projects/ntlmaps/ and then watch the video here
People on windows can install python from here and then follow the steps
ION proxy problem solved
Note:- If You face any problem please post back here….
PS:- every thing in Text form coming soon… (i am lazy)

People in MobiVision Workshop

MobiVision (Brain child of Subhendra Bhaiya) was a workshop conducted by people from LUG Manipal ( well not officially but everyone involved in it was from LUG Manipal ) as the name suggests it was on developing Application for mobile Plateform, basicly targeting Python for Series 60 and Android, We were expecting turnout of around 100 people and more the double turnout took us by surprise, it saw a partisipation of over 200 which comprised of guys/gals from First to Fourth year which was really amazing we even had people doing PG showing Interest, we had some trouble managing them in 2 rooms which were alloted to us but in the end every thing turned out pretty well. We had 2 Teams ready one for Python S60 and one for Android, Both teams did a great job and made Mobivision the most sucessfull Workshop in Techtatva 08.

Team MobiVision

Next was Techtatva 08 which is the annual Technical Fest of Manipal Institue of Technology, Manipal, Here again LUG Manipal was in full control ( and again not officially!!! ) we were to conduct events for the Computer / IT Catagory called ” PARAM ” and we planned to change the previously conducted events so as to make them fit in the 4 basic catagories of people –
1) ” MobiVision ” for Inovators here teams where to come up with a inovative Idea for Mobile Application and a prototype
2) ” Jour ” for Developers here teams were to make any one of the three Projects and give a Presentation and Demonstration of their product
3) ” CodeBytes ” for Programers the usual problem solving event with not so usual questions
4) ” Puzzle Mania ” for Every Day internet users comprising of all sorts of Puzzels
all the events saw good participation from all years and were prased for not having a single glitch.

Raunaq, Me and Nishant

I also made a Deligate and Event Registration system for managing and registering all the people coming for Techtatva 08 and also a CBT ( Computer Based Test ) system for priliminary rounds of some events, it was all basicly made in PHP and used MySQL as primary Database and was hosted on a Fedora 9 ( for those of you who dont know what it is — Its a GNU/Linux Distribution and also my Primary OS ) based server running Apache in Student Councels room because we/I were/was denined permition to host it on the main Manipal University server, they said “You are a Threat for our Network!!!” ??? which left me wonder what kind of stuff they do there and what did i do to them??? ( reason for which i got to know later ) anyways we managed to get a lab computer for using as a server, it had a AMD Athlon x3800 CPU, 80 GB HDD and 1GB RAM, which was all i needed for my work, the PC was formatted and fresh Fedora 9 was installed on it, after this all updates were applied which didn’t took much time as the connection there is not at all like I-ON and is at least 10 times faster ( well it was MAHE LAN and I-ON is WiFi but still!!! ) some changes in http.conf and iptables and it was ready. The System ran without a glitouch except when someone made the LAN cable for the server loose which made all on Registration Desks shouting but luckly everything was back online in 2-3 mins. The CBT’s also ran very good and results were decleared as soon as the alloted time was over and there were no objections.

CBT - updates, running on a lab PC for real time updates

I Love Python!!!!!!!

username = "Your username"
password = "Your Password"
interval = 10
data = {"loginID":username,"loginpassword":password,"flag":"0","popcheck":"0","submit":"Sign In"}
value = urllib.urlencode(data)
request = urllib2.Request("http://192.168.150.2:8080/clntAuth/clntAuth_main.jsp",value)
print "Logging In\nMade by Ankur - http://ankurs.com"
while (1):
        open = urllib2.urlopen(request)
        responce = open.read()
        for i in range (1,interval):
                print (interval-i),"min Till Next Login"
                time.sleep(60)
        print "Logging In\nMade by Ankur - http://ankurs.com"

or downlaod
run it by typing python ial.py
it uses urllib, urllib2 and time which are the default module, you have to change the username and password to your username and password, changing the interval changes the time interval in which auto login takes place. enjoy!!
PS – current it does no check if your connection is active or not, will add that soon

Removed because of objection form ION

old text avaliable here

Now to know how it works, if you want to know how it works then continue reading else there is no need to read further
By taking mac addresses they assign you IPs using DHCP based on the mac that they have so if you assign it yourself you have no need to use DHCP and everything works just fine
Enjoy!!!!

Note:- If you get IP conflict change your IP and try again

<script type="text/javascript">
function login()
{
document.loginframe.submit();
}
</script>
<body onload="login()" >
<form name="loginframe" method="post" action="http://192.168.150.2:8080/clntAuth/clntAuth_main.jsp">
<input type="submit" value="Sign In" >
<input type="hidden" name="loginID" value="your username">
<input type="hidden" name="loginpassword" value="your password">
<input type="hidden" name="flag" value="0">
<input type="hidden" name="popcheck" value="0">
</form>
</body>


Till here

This is a very simple method you can understand it just by reading the above code, i knew this method from a long time but have posted it now because of a recent event anyway dont forget to replace “your username” and “your password” to the actual one you are using
