Coming back from a week without podcasts , I have two great episodes to showcase this time around. Here’s to fantastic podcasts, then, and their continued, well-deserved success. Permalink.

I was a CS student long ago, but still remember the life. I’ve learned a lot since then and have a successful career. Perhaps I could have evolved much faster with a better initial understanding of this profession. Knowing the lessons I learned will help you avoid some of my mistakes.

Your quest is at an end for you have reached the home of Peramides 1 . This is a personal blog about things I’ve learnt, discovered, thought, or that I just need to write down somewhere because I always forget them. It’s a spiritual successor of my old WordPress blog. I needed something fresh so I built this using Jekyll/Octopress (I almost chose Hakyll but its documentation was scarce and outdated, and I’m not really proficient in Ha....

The idea that one could survive and prosper based on their merits alone is a comforting idea. If this story teaches us anything though, it teaches us that increasingly, it is nothing more than that — little more than a comforting notion in a world where mom and dad can open their wallets to make any door spring open before their baby. I signed eight years of my life away in exchange for a four-year education, and while I don’t regret that ..

I'm taking September off to work for some clients, so Lemma is temporarily on the back-burner. HOWEVER. Wednesday night a certain something arrived in the mail. I immediately tried it out with Half-Life 2 and was shocked at the massive improvement over DK1. I was so impressed that I've spent pretty much every waking minute since then trying to get it working in Lemma. Current status? It's very, very close. The VR itself is 1..

How can I learn to code? It’s a question I get a fair amount. The obvious answers are to checkout codecademey and Treehouse.

I first came across Rohan Anderson and his writing through a video titled “ The Smokehouse ”, where he talked about and demonstrated his efforts to construct a smokehouse completely by hand. Since that cool winter night almost a year ago now, I have continued following Rohan’s activities through his excellent blog, Whole Larder Love , and have linked to a number of his articles in the weeks and months since then. If my implicit endorseme..

When I was 18 years old, I started taking driving lessons. I practiced on an old Opel Astra, that was running on propane instead of normal gas, to save money. On my first lesson, we spent a large portion of the time going over the different tools and instruments available in the car. We covered many things at once. How to turn the signals, which pedal is the throttle, the break, and the clutch, how to use them to switch gears, how to turn l....

If you’re a reader of my code or of this blog , it’s no secret that I hack on a lot of puppet and vagrant . Recently I’ve fooled around with a bit of docker , too. I realized that the vagrant , environments I built for puppet-gluster and puppet-ipa needed to be generalized, and they needed new features too. Therefore… Introducing: Oh My Vagrant! Oh My Vagrant is an attempt to provide an easy to use development enviro..

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.

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..

This is a continuation of my ongoing Cabin Porn Roundup series, where I collect interesting pictures of cabins and cool stories about the outdoors from across the world and present them in a single location. 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....

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 ..

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....

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..

Jeff Kish is a contributing editor for Gear Junkie , a great site that publishes articles about the outdoors and the gear we humans can use to best tackle it. For the past two months, Jeff has been on a mission to hike the Pacific Northwest Trail, and post regular updates and gear reviews along the way. With this report, he has finally crossed the halfway point, and so I felt that now was as good a time as any to post a link here: if you, ..

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..
