The Kickstarter for Lemma launches on Monday! Keep an eye out, and tell your friends! Prepare yourself for tons of giant GIFs. You can click each one to watch a much faster HTML5 version (can't wait until the internet ecosystem finally lets us embed HTML5 gifs...) This week I revamped the materials... again. Check it out: It had some interesting implications for the "snake" enemy:

Very, very cool project from Josh Worth — both technically, and as a source of perspective for how vast space really is, and how small the earth — and, by extension, we — are. Permalink.

Nice to finally have some closure on this subject. I never got into Flappy Bird — I never even downloaded the game — but I couldn’t help but get sucked into the “discussion” — and I use that term loosely here — around the game, especially after its creator took Flappy Bird down at the peak of its popularity. I wish him good luck in the future; he has been remarkably blessed, and I have no doubt he will make good use of that good fortune. ..

After my presentation at UKNOF on SR , Mark Townsley asked me whether I'd be interested in presenting to his class at the Ecole Polytechnique in Paris, around the thinking (from an ops perspective) of delivering the 5218 concept of "net positive value" through the SR technology, and how the existing protocols that are available might measure up against the criteria that 5218 gives us to consider. We managed to co-ordinate logistics, and ..

Hi All, I set about to put together a new app and challenged myself to do the whole architecture on azure without spending a penny. The only caveat I set was that I should be able to scale if everything goes really well. So the basic components I’m using are: MongoDB - 500mb db offered on Azure Store by MongoLabs (having not played with mongo wanted to give it a go, you could also use SQL Azure free db or others) SendGrid - 20k emails..

Back when I was first exposed to programming language design, I decided it would be really cool if there were a language that let you define your own number types and then do all your programming within those number types. And since I get excited about math, I think of really exotic number types (Boolean rings, Gaussian integers, Octonions, oh my!). I imagined it would be a language feature, so I could do something like this:

So I was recently scheduled to do an AirPair pair programming session to help someone understand the various javascript functions available for asynchronous programming. This topic is key to writing correct code both in node.js and the browser, but it is indeed easy to see how things can be quite confusing when first encountering a myriad of functions that all seem to basically do the same thing. setTimeout, setImmediate, process.next....

Algorithm: Recognizing URLs within plain text, and displaying them as clickable links in HTML, in Wicket

I have just, out of necessity for a customer project, written code which takes user-entered plain text, and creates out of that HTML with URLs marked up as clickable links. Although marking up links in user-entered text is standard functionality, Stack Overflow would have you believe that it’s not something that should not be attempted, as it cannot be done perfectly. This is technically correct, however, users are accustomed to softwar..

This week I finished what will probably be the last map in the Kickstarter demo. It teaches the player about the "extended wall-run" ability, demonstrated here: Normally, you hold Shift to wall-run. Now you can just keep holding Shift after you run out of wall, and you'll keep going. I also fixed the water bugs from last week, so it looks much better now: I've been worried that I don't have time in the demo to introduce eve..

Introduction As I improve my knowledge and framework for a Go based web service I am building, I continue to go back and enhance my Beego Sample App . Something I just added recently was providing localized messages for validation errors. I was fortunate to find Nick Snyder's go-i18n package. Nick's package made it easy to support multiple languages for the Go web service I am writing. Abstracting go-i18n The go-i18n packa....

So I’ve recently been using lots of VM’s and I end up getting through them fairly quickly – deleting and creating them regularly. What I ended up with was loads of ghost services in the portal that were, once upon a time, associated with a VM in the distant past. Given PowerShell is awesome, I set about automating the removal of these using the azure cmdlts. The trick is that I don’t want to remove services or VM’s that are currently “S..

Lets Start With What the USD is backed by The USD is no longer backed by gold 1 , but by a promise that the US Government will pay its debt (in the form of payment the interest on (and sometime redeem) government securities when due). If these payments are not made to the debt holders (Corporations, China, treasury-bond holders) then a default would occur, which would shift international use of the USD into other currencies. This would f....

Git is something most of us, as developers, can't live without. However, Git may also behave like a double-edged sword, especially for less-than-seasoned developers like me, who inevitably ended up doing something stupid to my Git repository.

I recently came across JSCS and thought it would be a great addition to our git flow to enforce consistent code style for all of our JavaScript code. JSCS is a code style checker for JavaScript. It lets you decide if you prefer your if’s with or without a space after them; if you’re OK with declaring multiple variables with one var keyword; if your lines shouldn’t go over 80 characters; etc. A lot of it is a matter of taste of course, b....

Tomorrow morning at three o’clock, I will wake up three hours earlier than normal; within sixty minutes of getting out of bed, I will be on my way to the Pittsburgh International Airport; five hours after awakening — if all goes well, and weather permitting — my plane will take off bound for the Bahamian island of San Salvador where I will reside for a week as part of a geology class I enrolled in at the beginning of this semester. After se....

If you enjoyed my roundups even in the slightest, I encourage you to sign up for the book’s waiting list ; I did, and I can’t wait to give them a few doll..

Although written in the same vein as all those articles about Tim Cook where the collective discourse was invariably framed by the comparison to Steve Jobs and his legacy, published for much too long after Tim became Apple’s latest CEO, here such a format actually felt appropriate as the author — taking from Yukari Kane’s upcoming book Haunted Empire, Apple After Steve Jobs — did so to contrast the two very different leadership styles of ..

This is a guest post by my colleague Adam Lelkes. The goal of this primer is to introduce an important and beautiful tool from probability theory, a model of fair betting games called martingales. In this post I will assume that the reader is familiar with the basics of probability theory. For those that need to refresh their knowledge, Jeremy’s excellent primers (1, 2) are a good place to start.

Fantastic take ostensibly on the problems facing podcasters with regards to discoverability, but in reality a thinly-veiled critique of all those who complain about having the greatest undiscovered app, show, or website rather than focusing their efforts on bringing that undoubtedly exquisite labor of love to a broader audience. I have fallen into this trap in the past, so having a slap-in-the-face reality check like this one to keep me foc..
