kersny··on Do real developers use UML and other CASE tools?
Wouldn't that then be the best tool? Maybe not the best tool from an outside standpoint, but given the circumstances.

Real developers use the best tool for the job.
kersny··on Johnny Chung Lee, original investor in Kinect hacking
I think its pretty awesome that one of the Microsoft Kinect developers actually sponsored hacking it, even more so now that Microsoft is promoting it (http://www.pocket-lint.com/news/38701/microsoft-kinect-sdk-o...)
kersny··on Ask HN: RailsRumble, NodeKnockout, What else?
Django Dash is one: http://djangodash.com/

and Ludum Dare for Games: http://www.ludumdare.com/

kersny··on Show HN: Breakup Notifier
I literally laughed out loud when I saw this... great project. I'd start checking the Twilio blog (http://blog.twilio.com/) for contests and implement their API to do SMS and Call notifications, you might win something.
kersny··on Even Easier S3 Jekyll deployment
Inspired by soren's post (http://news.ycombinator.com/item?id=2241801), I decided do a little write up on my setup
kersny··on Deploy Websites on Amazon S3 using Jekyll and Git
I just set up something very similar last night, without git. I used http://s3tools.org/s3cmd in a simple bash script, which nicely replaced my previous rsync setup. Should be about $0.01 a month to run :)
kersny··on Ask HN: So I just bought Rap.io What should I build there?
I could see this going insanely viral. For monetization, once a song is done do crowd-funded bounties for the best song/music video.
kersny··on Ask HN: Are any of you at X where X is some college?
Carnegie Mellon? I'm starting this fall in CS.
kersny··on Ask HN: How to start creating stuff with Arduino?
Here are the answers to a similar question on StackOverflow a while back: http://stackoverflow.com/questions/1690284/getting-started-w...

kersny··on Ask HN: The ranking algorithm in 'the social network'
Ah, yes, my mistake. And I wonder how that copyright works... it seems as though these guys: http://digital.ipcprintservices.com/publication/?i=34502&... used the method for their project, although I don't think they made any money off of it. That article also describes Colley's matrix very well.
kersny··on What if OJ Simpson used Foursquare in 1994
Too easy to fake: http://compbio.cs.uic.edu/~mayank/4sq.html

Even with increased security, the hackers usually win.

kersny··on Ask HN: The ranking algorithm in 'the social network'
This is correct, and the equations in the movie were very much real. I thought it was funnily obvious when he called it "The algorithm for rating chess players", knowing what ELO was.

Here's "The Algorithm": http://imgur.com/e5myT

EDIT: In the intrest in contribution to discussion, two other methods for ranking are the Colley matrix from the BCS (http://www.colleyrankings.com/method.html) and I have used PageRank for a similar purpose before (http://michaelnielsen.org/blog/lectures-on-the-google-techno...).

kersny··on Gitmarks: A web bookmark manager built on git, with Delicious import
Not to be confused with Jackson Harper's Chrome extension to bookmark git repositories without watching them: https://chrome.google.com/extensions/detail/dbjampjhnhcfjgca...
kersny··on Strategies to Protect Against Distributed Denial of Service (DDoS) Attacks
1. Don't piss Anon off.
kersny··on Ask HN: nodejs, express and jade - worth it?
Although I have never built a "complete website" on the node.js stack, the time that I have spent developing on the platform has been very enjoyable and I've put a decent amount of effort in. There are many articles as well as github repositories that can teach you what you need to know to get up and running. I recommend https://github.com/ry/node/wiki and http://expressjs.com/ for reading on the subject. Good Luck!
