Yesterday Dan, Pradeep and I presented “y!Vmail: voicemail for your Yahoo! Mail” at the Yahoo! University Hack Day Contest, winning the award for the 2nd best Hack! (jump to the demo video )
Our team with judges Paul Tarjan and Rasmus Lerdorf
The adventure started when I heard about Yahoo!‘s Hack U event:
Join Yahoo! web experts including Rasmus Lerdorf, the creator of PHP, for a week of learning, hacking and fun! You’ll hear interesting tech talks, hacking tips and lessons, and get hands-on coding workshops where you’ll work with cutting-edge technology. The week’s events will culminate with our University Hack Day competition—a day-long festival of coding, camaraderie, demos, awards, food, music and jollity (it’s a real word, look it up).
Years ago when I was in my teens, I was an avid participant on the school / college tech fest circuit. Almost every major institution in and around Delhi would organize annual technical festivals, hosting programming contests and software demo competitions. This was where I got a chance to showcase my creations and meet other hackers. Winning these events became a good way for me to pay off those telephone bills — web development in the dial-up age was an expensive hobby!
I decided to enter the Hack Day contest just for fun; it had been a while since I participated in one of these. It wasn’t about winning this time; I just wanted to do the whole “idea to execution to demo” thing with a group of friends, and spend hours screaming at each other over STUPID hard-to-find bugs that are actually staring at you in the face, high-fiving every hour as a feature milestone was scratched off the todo-list. The reward: to be able to stand in front of a group of people and say “Hey guys, look what I made!.” (If it’s hard to appreciate what this feels like, this video might help.)
Yahoo! gave away a bunch of t-shirts, this was on one of them
3 days before the Hack Day, I had an idea about building a phone-based interface for email. The idea was simple enough to build in a day, but fun enough to make an enjoyable demo. The only problem: I was already in the midst of a “hack” daymonth of my own; VLDB was due 3 hours before the start of the Hack Day, and I was already sacrificing sleep for LaTeX and Python for more than a week. There was no way I was going to be able to do this alone. Enter fellow grad students Dan and Pradeep. I told them about the contest and my idea. While they are both expert hackers, I totally forgot about the fact that people in Operating Systems research don’t really do a lot of Web Programming: “PHP….? I’ve never…” said Dan. I pointed them to the Yahoo Developer Network site and returned to my research paper writing madness. Hopefully by Friday evening, I would have a web-savvy hack team.
On Friday, I took a quick nap after my paper deadline, and walked over to the Hack Fest area to meet my team (who had become PHP and telephony wizards by now) and load up on caffeine and sugar that the Yahoo! folks had set up for us.
They even had my favorite candy !
We split the work into two parts; Dan would build the phone interface while Pradeep and I would figure out the email and contacts API to write an email client backend. 7 hours later, we had the first version of our product up and running. We could call in and read emails. Happy with our progress, we decided that it would be wiser to go home and show up early next day. We ended up wasting a few hours the next morning worrying about the presentation: the lecture hall had spotty cellphone coverage, a deal-killer for a phone demo! Pradeep made a breakthrough here, discovering that an obscure panel on the wall was actually a secret speakerphone. Having resolved demo issues, we resumed coding and plugged in the remaining features: navigating through emails, email summarization, and email prioritization. The friendly timestamps feature (“4 minutes ago”) was stolen from my blog’s code (i.e. the Status header of this blog).
Around 3:30pm on Saturday, we updated our hackday entry:
y!Vmail
by Arnab Nandi, Daniel Peek, Pradeep Padala
“Not everyone has a computer, but everyone has a phone.”
This hack allows people to access their Yahoo! mail through a 1-800 number, using ANY touch-tone phone.
Press 0 to open, * and # to navigate, 7 to delete. We figure out which emails are important, and read them first. We summarize long emails so that you dont have to listen to all of it. If you want to talk to the person, just press 5 — we’ll connect you.APIs used: BBAuth, OpenMail, Contacts API, Term Extraction API
Hack presentations started at 4:00pm on Saturday. I started with a 20-second powerpoint pitch, followed by a rather entertaining demo. Using the lecture hall’s speakerphone we had the lecture hall call our service. Entering the correct PIN logged me in, which resulted in an entire roomful of people were now hearing the words “Welcome to y!Vmail. You have 5 new emails…”

Here’s a short video walk through of our app:

A few minutes after the presentation ended, the prizes were announced. We ranked second. The winning hack was Brandon Kwaselow’s “Points of WOE”; a native iPhone app that allowed browsing and creation of placemarks on Yahoo! Maps. Congratulations, Brandon!
Overall, this was a very exciting and enjoyable event; I had a rocking good time hanging out with the Yahoo! folks and getting a cool project out the door with around 15 hours of work. I end with some lessons, acquired over years of doing demo contests:
- Be creative, but avoid feature creep.
- Split up into sub-teams, but make sure you’re pair programming most of the time.
- Get Version 0 done Super Super Early. Then polish, polish, polish.
- Reuse (with attribution) as much code as you can.
- Take lots of breaks, make friends, and have fun.

Shout outs: Folks at Twilio for making the coolest telephony API in the universe!
What other people have to say:
good show man!
Hi Arnab,
Great writeup… can you make the vimeo video public? I’m itching to see it. Either that, or I should see a doctor :)

@jeff: D’oh! problem fixed. Sorry about that!
Great stuff man. Hacking that app in 15 hours is quite a feat. Congratulations! I especially loved the idea of using term extractor for summarizing the email.
Very cool hack, congrats. This is the future of the web and you’ve shown the world that we are ready.
Pffffff I don`t know I`m a realtor i use already a voicemailtel.com service , and i don`t know if this yVmail can do much, Or maybe this is just a beta Version
balea: I’m glad you’re using Voicemailtel, you seem to be happy with it. yVmail was made as a “hack” in a 24 hour programming contest, so it’s not even “beta”. :)
:), congratulations , good luck. Just one questions Is this has anything to do with Unified Communications?
