http://www.quantumbiosystems.com an IC that can read DNA without any complicated chemistry and on a device that costs dollars. It's cool not only because it could revolutionize medical research and diagnostics. But also because it gives the world a fundamental new class of sensor on which new applications will be developed for years to come.

What are the error rates like on this tech at present?

Early days, <1% substitution but homopolyer issues (~10%)

A distributed, encrypted file backup system. https://github.com/ConceptPending/fincrypt Backups are verified at regular intervals to reduce the amount of trust needed in the system, and every file is stored multiple times. Eventually the goal is to attach a marketplace where end users will pay for the space they use and those who provide storage will get paid for doing so.

I had similar idea a while ago, although it didn't involve bitcoins and I never actually acted on it. How do you solve the problem of an evil storage node provider who detects that you're trying to recover a file from backup, blocks it and sends you a "transfer X BTC to my account to get your data back" email?

Files are stored in multiple places and Storage Nodes will be asked to send files on a regular basis, for example, to ensure there is sufficient redundancy for a given file or if the end user wants to sync the files to a new computer.

The storage nodes also have no knowledge of who owns the file or what the contents are. Combined with the fact that they'd immediately stop getting paid for the other files they're hosting, it seems like the ROI for one of those evil nodes is pretty negative.

Been working on a book on asshole Javascript. A/B testing two titles: Javascript Technical Interview Questions[0] and Underhanded Javascript[1]

It's cool because the way it came to be was entirely accidental. I was working on much larger VM project when I told my friends "Javascript is so shit I can write a book about it". One of my friends egged me on, and I accidentally wrote 2 chapters the day HN went down. I'm now at 10 chapters and still writing.

Also, I've never done anything like this so quickly before

I've restarted working on http://myshigoto.com (for finding English-speaking jobs in Japan) after doing pretty much nothing to it since creating it five years ago - scratching my own itch. With the pick up in the Japanese economy recently I've noticed a few nice comments about it on blogs and forums. Not only is it satisfying to think I've helped people find a job, it's given me the incentive to improve it and maybe…

There's some html in Similar Entries: http://myshigoto.com/node/72209 I like your design, it's simple, warm. I did something similar but for all types of ads (including jobs) http://oglos.info/

Thanks for the compliment and bug report - I've just fixed it manually until I can work out how to prevent it from happening again.

I like the look of Oglos. Very clean and easy to browse.

I'm working on a WP8 app for Kraken (the bitcoin exchange): http://www.windowsphone.com/s?appid=a3857353-599a-434f-8293-....

It's fully functional. It shows live rates, your open & closed orders, your balance and it has the ability to create and close orders.

I think it's cool because Windows Phone is the first platform that has a Kraken app, and this app is arguably the best bitcoin app on the WP platform.

http://lnav.org -- A fancy log file viewer for the terminal. Cool because it provides a lot of features over 'tail -f' without being more complicated to use. Just point lnav at your files at it will auto-detect the messages format and present you with a single time-ordered view of your log files.

It also has more advanced features (http://lnav.org/features/) that are usually only available in server-based solutions, like doing SQL queries over log messages.

http://www.passinglives.com an online obituary site, with a focus on long form photo obituaries so people are able to write a short story of someone's life rather than a few lines that you would find in a newspaper. A couple of sites in the States have a similar theme, but here in Europe still very much a new idea. We think it's cool because it's everything a newspaper obituary isn't - very affordable, global, interactive, perpetual, shareable. It's also ad free which makes it a respectable place to come to pay tribute to loved ones.

http://sdk.tradingmotion.com a high-level API for developing automatic trading systems, with open source examples. It is cool because it aims to democratize algorithmic trading development using a geek approach. Algos are integrated with our marketplace http://isystems.com where clients all around the world use them on real accounts for a monthly fee.

This is very cool. Algorithm trading design is a side hobby of mine, and see the value in this. Good luck with the project.

If you get in touch tyler [at] codenvy.com, we'd like to offer you a special integration for free that can help your developer-users.

Helium ( http://heliumhq.com ) is a library for web automation. It's cool because it takes 66% less code and 75% less effort to use than the de-facto standard for web automation, Selenium.

This is neat.

How does it handle logins that popup, eg, Login with Twitter?
