After Ben Hewitt’s recent essay on his approach to and the benefits of unschooling, Outside Online has another great article on the subject, this time offering some helpful suggestions to those looking to differ from the norm. Again, not the time to share my thoughts on this subject quite yet, but keep this one, too, in the back of your mind when I do. Permalink.

The web has come far from the days of AJAX polling to where the browser constantly polled the server for updates. In general there are a few ways to get a message from a server to a browser, each of these has their benefits and drawbacks.

Governments collect and publish enormous amounts of data, but much of that data isn't accessible or promoted openly to the general public. This is often because governments have limited resources with which to engage the citizens and demonstrate the power and impact this data can have. As Australian governments shift further and further towards opening their data, the power of the crowd has meant that amazing ideas can come from anywhere an..

Steve Hannah of new iOS pipeline fame (as well as a ton of open source Codename One libraries and projects you can see here ), has just announced one of his more ambitious undertakings: Mirah support for Codename One . Mirah is effectively Ruby without the performance penalty of an overly dynamic language, it’s compiled to bytecode and can thus be compiled with the Codename One build servers.

Over the last few years I've grown rather accustomed to listening to my Pandora while working, even upgrading to PandoraOne so that I can enjoy my music without interruptions 1. However, I found myself avoiding Pandora earlier this year. Why? Pandora uses Flash for the web and Air for the desktop, presumably in order to annihilate the battery on my laptop. 2 The problem isn't Pandora though, it's Flash. What if I could use Pandora without F..

Much like my “This Week in Podcasts” series, I feature only the best of the best here. Enjoy. Permalink.

Introduction I was thinking about how the compiler looks to protect the code we write when it can. Invalid memory access checks are one type of safety check the compiler adds to our code. We might think that this "extra code" is hurting our performance and maybe over billions of iterative operations it is. However, these checks can prevent our code from causing damage to the systems we are running on. The compiler is essentially reportin....

My interview today is with Michael Hunter, a senior software developer, who’s been with Microsoft for 14 years now. He helps the teams evaluate the quality of their products. When he’s not at work, he can be seen city hiking around Seattle and spending time with his fiancée and her giant cat (the furry one in the photo!). Read more about his “You Are Not Done Yet” checklist and other good stuff at http://www.thebraidytester.com.

Problem: Two players take turns moving a rook on an 8×8 chessboard. The rook is only allowed to move south or west (but not both in a single turn), and may move any number of squares in the chosen direction on a turn. The loser is the player who first cannot move the rook. What is the optimal play for any starting position? rook-board Solution: Take advantage of the symmetry of the board.

For the past five months I have continued publishing a series of articles dubbed “This Week in Podcasts”. Born of my love for the medium, I have curated these lists to great results, and to my great enjoyment. However, this week I find myself in an unfortunate position: although I have worked diligently to get through my growing queue of unplayed podcast episodes over the past week, I have yet to find anything that merits inclusion in this ..

This material is out of date by now. We recommend checking out the Codename One Academy . We’ve uploaded the full course video cast as a youtube playlist, just go thru the parts and in an hour and some change you should understand the basics of creating a simple Codename One client server application that runs on all mobile devices. The Udemy course is still there and probably useful if you live in a region where youtube is..

John Gruber with the one article you ought to read before Apple announces its new iPhones in a few weeks, and the single article you ought to read afterwards as well when searching for the reasons Apple chose these dimensions. Minus the somewhat unimaginative title, a great piece, albeit somewhat hard to follow at times given the complexity of the topic at hand and the factors playing into his assumptions. Permalink.

If you have not heard about the ALS Ice Bucket Challenge I would be surprised. It’s everywhere nowadays, being done by celebrities alike. After being challenged by my children there was only one person, or should I say Gopher, I knew I needed to nominate. The Gopher took to the challenge and here it is: I would like to thank my daughter for spending time today filming and editing the video. She is a senior member of the award wi..

Although I have never spent much time on Reddit, I once perused Digg with the same frequency that I opened Twitter and my RSS reader; sometimes, I even opted for the former in place of the latter. Similarly, I favored Hacker News over the more popular Techmeme for a time. In both cases though, despite all the enjoyment I found in these sites, I eventually abandoned each of them as the value they provided continued a disappointing slide towa..

If your project is a Portable Class Library and you want it to run with the .NET Framework 4 well, you are in for a few surprises. Especially so if you are using InstallShield for building your deployment package. We’ve been going through this a few days ago and it’s been kind of a wild ride. I thought I could pin the whole thing down so that others might enjoy a painless journey through all this mess. Portable Class Libraries and .NET Fra....

Since the time Mingle was first released as a SaaS product, it has gone through a lot of changes. Most of those changes have been towards enabling Mingle to work in distributed environments on the cloud. In our journey, we learnt a lot about the cloud and how to build for it instead of fighting it. I will try to unfold our progress and showcase a tool - EbDeployer, which we built along the way (to enable continuous deployments on AWS).

Ben Hewitt puts forth a very good case not seeking to argumentatively justify the notion of unschooling, but rather simply to explain his motivations behind choosing it for his two children in a fantastic article for Outside Online titled “ We Don’t Need no Education ”. As a homeschooler myself whose education resided somewhere between the traditional system and Ben’s approach on the spectrum of organized learning, I have been fortunate en..

Seagate has just publicly announced 8TB HDD’s in a 3.5" form factor. I decided to do some rough calculations to understand the density a bit better… Note: I have decided to ignore the distinction between Terabytes (TB) and Tebibytes (TiB) , since I always work in base 2, but I hate the -bi naming conventions. Seagate is most likely announcing an 8 TB HDD, which is actually smaller than a true 8TiB drive. If you don’t know the diffe..

Greedy algorithms are by far one of the easiest and most well-understood algorithmic techniques. There is a wealth of variations, but at its core the greedy algorithm optimizes something using the natural rule, “pick what looks best” at any step. So a greedy routing algorithm would say to a routing problem: “You want to visit all these locations with minimum travel time? Let’s start by going to the closest one. And from there to the next cl..
