I'm working on a web app framework / cms for node.js built on express.js and mongo called KeystoneJS, and have been for a few months. Keystone makes it easier to get a blog / website / web app up and running without a lot of the module research or boilerplate code node.js usually requires. It also provides a beautiful, useful admin UI (think activeadmin for rails). It's open source (MIT), and cool because... * There…

There's also a demo online at http://demo.keystonejs.com - it's very simple but you get the idea of how to structure an app, the source code is on github.

If you want to check out the admin ui, you can sign in to the demo at http://demo.keystonejs.com/keystone with the username demo@keystonejs.com and the password demo.

http://www.timmclean.net/json-editor/ A code editor that uses knowledge of a programming language's grammar. It's cool because it should be significantly more efficient than working in vim/emacs, and will allow powerful scripting capabilities and macros to transform code structurally, instead of as text.

Hey there fellow UW alumni! I'm trying to write a similar kind of structured code editor. We should team up.

Emailed!

http://cyclingplanner.com -- a season planner and training/results tracker for competitive cyclists.

It's cool because:

* A lot of cyclists are still planning on paper or spreadsheet, including me before I started working on this. It scratches my own itch and I believe I can make the experience a lot better.

* It collaborates instead of competes with services like Strava and Garmin Connect. Because it's using their API's cyclists can keep logging their workouts on those services and view detailed analytics on cyclingplanner.

* It's my first serious attempt at bootstrapping a software product and I've learned a ton of interesting stuff aside from coding so far.

I wrote a spectral analysis library called udsp: http://www.eliteraspberries.com/doc/udsp-user-guide.html https://code.google.com/p/udsp/ In the future it will include: * support for more FFT libraries, like FFTW; * some signals processing functions, such as basic frequency modulation/demodulation; and * a NumPy-compatible Python interface. Its best feature at the moment is convolution and correlation.

Awesome. I'll keep an eye on this, thanks.

Upbeat (https://www.upbeatapp.com/) -- hackernews meets soundcloud.

It's cool because:

* Users can democratically decide which music is popular.

* Music is browseable by genre, and filterable by sub genre.

* Users can save songs and add them to a queue for later listening.

* Powered by Angular.js, Node.js, Redis.

* Average server response time: 9ms

* Bootstrapped by 3 friends, in less than 1 month, only working nights and weekends.

* Already profitable.

I'm working on a next generation programming environment for front-end browser development that combines version control and dependency management. It is called lit and the current alpha iteration is at http://www.corslit.com I just introduced static semantically versioned builds and started the process of self-hosting. The interesting thing about lit is that it allows for modern professional development without any…

What??

Unless you have an express license or permission to make use of a derived work of Coors's trademarks, I'd just say that this is not so cool. Specifically, I doubt that you actually registered a "CorsLit" trademark, which completely mimicks the one by Coors Light, by keeping the ® symbol in place. Any trademark office would have rejected this registration.

I'm just an engineer, telling you this nicely. I'm sure, Coors will find other words, should your tool become more popular.

This thread needs more hardware. I'm making bike lights. First a little story. I was late to class one day in March, pothole season. I was cruising in the drops, when I came up to a T intersection. A van pulls up, and stops at the stop sign. As I approach the intersection, I see a pothole, swerve to avoid the hole, and the van pulls forward. I have about 1 second before I hit the van, land with my back on the hood, s…

Cool! How do you plan to deal with theft? Most bike lights are trivial to steal. I tend to avoid the fancy ones since in my experience lights disappear immediately as soon as the bike's parked (unless I remove them and put them in a bag every time I park, but that's a pain). Curious how you're addressing that.

SilverAir - An athletic shirt that doesn't smell and designed to be worn at the gym and for everyday wear. demo@ http://www.yathletics.com It's cool because: It's made using pure silver which kills the odor-causing bacteria in your sweat, so you can -wear this shirt for your entire day and feel fresh, -reuse the shirt more often (i do). The fabric is completely new and something I made with my manufacturers from scra…

This sounds good, there should be more shirts like this around. I'm curious if you are aware of Silverescent fabric, which is much the same idea, and if your have made additional unique improvements?

Epiphany Eyewear smart glasses: http://epiphanyeyewear.com

It's cool because these glasses are stylish enough that they are a fashion item, and have appeared on the runway at New York Fashion Week: https://yougen.tv/video/beddc3d4-784f-40ab-8066-652ac8e3f694...

It's cool because you can record two-handed activities such as kayaking: https://yougen.tv/video/9b406d41-8e68-43fc-904f-f12ce688f610...

It's cool because everyone from Miss California https://yougen.tv/video/db0c3dd0-846c-458c-8d53-cd2802b00534... to my barber https://yougen.tv/video/92f9308b-d6a9-46a4-95f9-39da0700f9cb... instantly sees the appeal of recording and sharing your memories with your friends

That sounds useful! I signed up for your newsletter. I'm curious if you have a series of screenshots or something showing it in use?

Thanks for signing up for the newsletter! I couldn't figure out which person you were based on your HN name. So I couldn't email you screenshots. Email me here! blog.goodsense.io/contact

I'd be interested too! Why not just put up some screenshots on the website? For the time being (and for future readers of this thread), you could just use a temporary URL, such as
