What’s my twitter reputation score ?

1 Reply

Last month, Twitter founder Evan Williams announced during the Web 2.0 summit that Twitter.com internally keeps a record of every users reputation score.  This made me wonder how do they calculate each users reputation mathematically. After some thought, I charted out a few parameters based on which they could possibly arrive at a quantitative measure of a users popularity on twitter. Here are some of my conclusions,

Number of followers: This factor contributes heavily to the score. More the followers, more is ones reputation. But its not just the number which decides the reputation. Each follower has his own reputation on twitter which will contribute to the user he follows. If a users reputation was only dependant on his followers, then a recursive algorithm would be required to accurately determine one’s reputation. Again the problem will arise when there are cyclic links, i.e. you are followed by a follower who is being followed by someone whom you are following, which will make it an infinite cycle. So the algorithm should stop the branching process as soon as cyclic links are detected. But most probably twitter.com would decide on the depth of penetration for each calculation beforehand.

Also there are certain users who back follow other users who are following them. Such cases will give rise to high rates of cyclic links and hence should not contribute much to the reputation calculation.

Number of retweets: You are definitely reputed if a significant number of users retweet your tweets regularly. So number of retweets coupled with the individual reputation of the user who is retweeting your tweet will add to your reputation score.

Number of mentions: If someone with a high individual reputation @mentions you, then your reputation score should increase.

mentions, favourites, listings etc….. todo

In the meantime checkout http://www.twitter-reputation.com. It is a small experimental page which I set up for finding out your own twitter reputation score based on the parameters listed above. I used the twitter @anywhere javascript API inspite of its limitations , instead of using the more stable PHP api, just to minimize server side bandwidth being used up for fetching user info.

Textoo : iPhone (and now Android) app to send free SMS using web gateways

4 Replies

History of Textoo

It all started back in 2010, when I had written a PHP script to send SMS through different Indian SMS gateways (see blog post on this). I would go around different websites trying to publicize this PHP script so that I would get more hits on my blog as well. In some of the blogs I had noticed different J2ME apps which send free SMS and were quite famous. But none of them had ported their apps to iphone and android platforms. A quick search revealed only the 160by2 official app which can do this.
Then I thought, Why not make a small iPhone app which can provide a client user interface to compose messages and then send the message using my own PHP script which I had already made by then. Since then, I started exploring the Appcelerator Titanium framework which was a vry impressive tool to create iPhone and Android apps using plain Javascript syntax. So I applied for both iOS developer access and Android market access by paying 99$ and 25$ respectively.
Once I got through the membership requirements, I started coding the UI in Titanium. And within a few weeks, the iPhone app was ready. The app would connect to my PHP script which would send the messages through the gateways and then return the result back to the app. The app was quite simple and had only 3 views. “Compose message” where you actually type the message after choosing your contacts from the phone addressbook, the “Outbox” view where you see the sent messages, and the “Settings” view where you add the gateways and account details.
After uploading the finished app to App store and getting it approved, I tried making it a paid app for 0.99$ The first few days I received around 1-5 sales a day. But people started complaining about some bugs in the app. And also there were a few problems with the PHP script. So I decided to make it free after a week of sales, so that I can get myself some time to fix the bugs. Since then it remained free and I spent minimal time of enhancing the app and the app continued to be downloaded for almost 6months with an avergae of 20-50 downloads a day.
I kept myself busy working on some freelancing projects on odesk.com and never actually thought of working on the app itself. But one of the iPhone projects which I had taken up on odesk got scrapped mid way through it. I did receive payment for the effort I had put in, but the app was not complete and the codebase was never used anywhere. Instead of scrapping the whole thing, I planned to use in the next version of the iPhone app and started working on the SMS app again.
But this time there was a big change. The app wouldnt send the SMS through my server/PHP script, but instead will connect directly to the gateway website. This way the load on my server would be minimal, and the gateway website would be happy to see all the HTTP requests coming from different IP addresses instead of my server addresses.
So since then, I spent most of my free time in working on the new version of the app and the new version was named Textoo Pro which can be downloaded here

What does it do ?

Textoo connects to major free SMS websites like way2sms, 160by2 etc and sends your SMS for free. It is a multi-account group-SMS app which can be thought of like a pidgin for SMS websites. You add your account username & password on to your app and instead of you going manually to the website and sending your messages, the app will automate it for you. The main purpose of the app is to give back the native texting experience to the end user even when they wish to use free SMS gateways.

Update: Android app also available.

About

Hey there, My Name is Kiran Kumar (so is the name of this site) and I am a 23 yr old web developer from Mangalore, India. This blog is a place for me to share my thoughts and my contributions to the open source community. Apart from that, this website is my face on the internet where I publish links to my work and a medium for you guys to reach me anytime. You have reached the about me page on my blog and I should say that this was one of the most difficult part of writing a blog, i.e, writing about thyself. So here it goes,

I am a Chemical engineer by degree, Oracle employee by the day and a freelance developer by the night

My interest in the web technologies started in late 2005 when I became a part of the web enthusiasts club at my college; NITK Surathkal. By then I had already decided that I would pursue chemical engineering as I had no clear cut idea on what specialisation to choose. But slowly my interests in web technologies started to captivate me and I started spending most of my time working on the web. In my college, I started becoming known for the websites I designed and the posters I created. In my free time I had learnt a lot of different technologies on my own. My first love was for SWiSH , an alternative to Macromedia Flash 5 at that time. I liked to create fancy text effects and make small flash movies using Swish. Slowly, I moved on to 3dsmax, to enter into the world of visual effects. But the hardware config of my desktop prevented me from getting too close to CGI. Simple 3d scenes took a lot of time to be rendered, and when the rendering time went to the magnitude of days coupled with the frequency of power cuts in India , it became an impossible feat to get anything out of it.

Then I found my new interest in PHP after one of my friends told me about it. And since then, I have been actively involved in PHP development. To me, the simplicity of the language combined with the power of the open source community always gave way to endless possibilities. Along with PHP came all its friends. Javascript, HTML, Flash, Photoshop, I loved them all !

I worked on a couple of different softwares/technologies and here is the list of things which I can recall right now :

  1. Rating: ★★★★★★★★★☆ PHP 5
  2. Rating: ★★★★★★★★☆☆ ExtJS framework
  3. Rating: ★★★★★★★★☆☆ Flash CS3 & Actionscript 3 -
  4. Rating: ★★★★★★★½☆☆ HTML & CSS :

  7. Rating: ★★★★★★½☆☆☆ Selenium & QTP UI automation

  9. Rating: ★★★★★★½☆☆☆ Photoshop
  10. Rating: ★★★★★★☆☆☆☆ VBscript & VB app design -
  11. Rating: ★★★★★☆☆☆☆☆ Google sketchup 3d modelling & rendering

  15. Rating: ★★★★☆☆☆☆☆☆ Matlab coding & GUI
  16. Rating: ★★★☆☆☆☆☆☆☆ Autocad (2d only)
  17. Rating: ★★☆☆☆☆☆☆☆☆ HP Quality center OTA API

I worked on a small content management system of my own which , in the final year of my college this helped me get a job in Oracle and be a part of Content Management (ECM) team in Oracle. At Oracle, I am a part of Middleware suite globalization team where I work with people from Beijing, Tokyo and San Francisco on Oracle’s acquired as well as in-house ERP applications. The toughest part of the job is learning to understand the accents used by different people.[Update: I now work as a mobile developer at an e-commerce startup flipkart.com]

Until recently, I was only involved in web based projects, but the day I can across Appecelerator’s Titanium framework, I said ‘this is definitely my cup of tea’.For the last 6 months, I have been busy  developing native applications for iPhone & Android using the Titanium framework and I absolutely love it.[Update: I have started hating it now. Its very difficult to manage titanium projects when they become big]

I am passionate about my work and I always love to learn new things. I hate limiting myself to a single domain and always push myself hard to explore new interests which can keep me occupied all the time. People may call it ‘lack of focus’ , hyper-wandering-mind or a Jackass of all trades ! But its just the way I am designed. There hasnt been a day where I dont get a tingly feeling about learning or doing something new. But most of my work have been in varied domain, and are unorganized.

I think that much text should be good enough for you to give a glimpse into my life, if you like to get in touch with me send me a mail, or chat with me, or follow me on twitter or drop in a comment.

I am now working on the creation of a mobile phone application for Android and Iphone which will allow you to send free SMS using the PHP API which I created a month back . This is the domain I never explored before, so will take a bit longer to come up with something useful. Hopefully, I can finish it by the end of this week, so that mid of next week, I can release it here. Follow me on twitter(@kiransmile) to stay updated on the latest posts.

This is a mobile application for iPhone 4 and Android 1.6 which will allow you to send SMS messages to India, UAE, Singapore, Kuwait etc using the free web based SMS gateways like 160by2, way2sms etc. Of course, you will need to register on the respective gateway websites to get an account, afterwhich you push in the accoutn details into the app using an easy to use interface.
