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…

http://i.imgur.com/KeX2Fb3h.jpg That's one hell of a print. Maybe try lowering the temperature? What are you slicing it with?

That wasn't intended to be the final one, but I made it and it worked. It was printed with support material that peeled off a little too strongly, exfoliating the back surface. The orientation is kind of tricky as there's a lip/groove interface between the front and back of the case which needs to be cosmetically clean to ensure a snug fit, so the only way to get that to work well is to print it with the back down, but there's a 'hood' over the ethernet connector that disallows printing directly onto the back. Slicing with slic3r.

I'm writing a book about the many ways well-intentioned scientists can (and usually do) screw up statistics: http://www.refsmmat.com/statistics/ I started when I was an undergraduate physics major. My entire statistics education consisted of thirty minutes being told not to use R^2. I started reading about statistical abuses and realized that I would probably have committed most of them had I published research -- my…

Interesting. My statistics knowledge has become rusty lately. I want to re-learn the basics before reading this. Can you tell me any resource (doesn't necessarily have to be a book)? P.S: I'm interested in knowing stuff like 'why square-root of variance is standard deviation?". Concepts.

You might find OpenIntro Statistics helpful:

http://www.openintro.org/stat/textbook.php

It's a free online statistics textbook, also available in print. I haven't used it extensively, so I can't vouch for its quality -- actually, I complain about it a bit in Statistics Done Wrong. But I've never come across a very good conceptual introduction to statistics, so this is roughly the best I know.

There are also amusing variations, like the cartoon guide to statistics:

If you find a useful resource, I'd like to hear what worked for you.

Blogvio (http://www.blogvio.com) - add beautiful widgets to your website.

It's cool because you don't need to do any coding to add beautiful and custom galleries, video players, mp3 players, and any other types of widgets to your website. Just copy/paste an embed code and you're done.

This helps you a lot especially if you're an agency or freelancer, or if you're using a publishing tool such as Wix, SquareSpace, Weebly, etc - where you don't have access to a server to upload files.

http://xoxo.gl (hugs and kisses, good luck) - a web app to play family-friendly, traditional board games. Still prototyping for now. My goal is wide in scope: to build a site that allows you to take a few minutes to have a positive social interaction with friends and strangers. An anti-Zynga, if you like. I still have a lot to do. With a goal of universal accessibility, I am working on progressive enhancement - makin…

I like the sound of this, but there's nothing much on that site yet. Where can I subscribe for updates?

Thanks for the compliment :)

If you sign up at http://xoxo.gl/ with an e-mail address then I'll let you know when there's more to see.

Otherwise you can contact me for a chat ronald@xoxo.gl

Currently working on a mobile security application to help easily teach, implement and manage the physical security of human rights defenders, activists and journalists. Right now there is nothing out there that does this, so hoping it will get a lot of use.

I'm not the best in terms of technical ability so if anyone wants to donate time - especially app developers, LAMP stack guys, UI/UX or testers then please drop me a mail to secfirstmd@gmail.com

A gamified course management system for colleges (http://www.usebackpack.com)

It is cool because: * It has all features to stay updated about your college courses in a very easy user experience. * It has game elements that keep students engaged and have fun while learning.

InputFarm (http://www.inputfarm.com)

- Input Farm provides quick website design reviews from expert designers for $75 (but we're giving them away to HN users now - see here: https://medium.com/p/8a87429d26cb )

It's cool because: - I've been a web developer for 10+ years and quite often i get 'stuck' on making a website better. I don't need a designer to do a 'full re-design', i just need a few pointers on how to make my website better.

- I need 'fresh eyes' on my website

- I need confirmation that i don't need to start over and waste a bunch of time!

Currently building out http://forever.fm , an automatically-beatmatched radio stream of popular music from around the web. Built out the real-time music streaming backend in a mix of Python, C++ and Golang, just submitted the iOS client to the App Store, and am currently finishing up the Android client. (Along the way, I also built my own distributed, persistent version of Unix pipes on Redis: http://github.com/psobo…

Nice to stumble upon forever.fm on this thread. I like it a lot and been listening to it for some time.

pganalyze ( https://pganalyze.com/ ) - Performance Monitoring for PostgreSQL databases. Its cool because: We visualise the metrics & counters that are usually hidden away in PostgreSQL internal tables. Plus we check that your database is fast and configured correctly. Also: I'm a techie with a UX hat, and data visualisation and pattern matching is fun :)

We use PostgreSQL for a lot of our applications, but I was hoping for a Paul Graham analyzer.
