I had an itch to scratch , and I wanted to get a bit more familiar with Openshift . I had used it in the past, but it was time to have another go. The app and the code are now available. Feel free to check out: https://pdfdoc-purpleidea.rhcloud.com/ This is a simple app that takes the URL of a markdown file on GitHub, and outputs a pandoc converted PDF. I wanted to use pandoc specifically, because it produces PDF's that were b..

Just a quick update this week to confirm that I am in fact alive. The iOS contract game is just about done. I'm pretty happy with it. Now it's back to work on Lemma: I'll be running a booth, speaking, and participating in a panel at the Ohio Game Dev Expo next weekend! Come on out and hang with us!

Most (all?) programming languages write assignment with the destination variable on the left hand side, i.e. a = b+c;
Therefore most (all?) programmers are familiar with the destination for an operation being on the left hand side. Therefore, I think, when designing functions or commands doing copying or assignment, the result should also be on the left hand side. Example: memcpy in C. Counter-example (which confuses me): Array.cop..

Wow! I love your app because I start out completely useless. I’m fumbling up this learning curve and I have no idea what I’ll be able to do once I spend the time to master it! — no user ever Start your users with this feeling: Credit: reddit …before you start them at level 1:

Aggregating Apache logs with Fluentd and Amazon S3

HackerEarth infrastructure is hosted on Amazon services. At any given point of time many webservers are running concurrently serving thousands of requests. This generates tons of access and error logs on each server separately. The task here was to parse the logs on all these webservers and store them at one place in a format that can further be used to derive meaningful insights from the data. We tried to accomplish this using fluentd and....

https://github.com/SonOfLilit/quickbmc/archive/gh-pages.zip To change it into your own, you will need to edit the .html file with a text editor like Notepad++. It's not complicated - just look for text you see in the rendered version (when you open it in the browser) and you'll know where you need to make changes.

Hello , I noticed you used a template for your previous business model canvas . Would you mind sharing that template with me ?

I’ve written about snail breeding here before, at length. However, since I now want snail behavior to go through the brain I had to rework the trigger that led to two snails mating and producing offspring. A few different things had to be prototyped to make this work, especially because in a snail’s mind there is no real way of distinguishing food from another snail without learning from experience and some basic instincts to guide the way.

UPDATE : I created a gem to cover the functionality of this post. Visit its homepage here . I was working on my application and I wanted to write some RSpec tests for some controllers having before_filter for some actions. I didn’t want to explicitly test the behaviour of the filter since it was already tested in another context. I only wanted to test that it is being executed. Let’s assume that this is our controller: class Fo....

Lately, I’ve been trying to find possible memory leaks in a rails 3.2.x application. NOT easy, believe me… Anyway, after visiting almost every single result from googling rails memory leak , I learned something I didn’t know. Symbols in ruby never die. ( Update 2016: No more the case for the latest ruby versions) . Given that, I wrote some code to track the creation of symbols in the application by rendering a debugging kind of panel....

This weekend I spent some time migrating my Minecraft server a good 700 miles closer to my house. The new server is ~30 milliseconds closer. If you play games, you probably know how huge that can be. So, how did I move data to the new server? FTP, right? No. Definitely no. Why not FTP? FTP is plain-text Unless you're using something like FTPS, you'll be sending your server credentials across the wire in plain text, so anyone sitting between..

Introduction It is idiomatic in Go to use the error interface type as the return type for any error that is going to be returned from a function or method. This interface is used by all the functions and methods in the standard library that return errors. For example, here is the declaration for the Get method from the http package: Listing 1.1

Last Friday night I attended what was apparently the first ever Laravel Meetup in Sweden. I’m glad I actually made myself go, because I’m not really good with social engagements. I don’t tend to go out much and sometimes end up just not bothering and staying home at the last minute.

I previously showed you how to Load a Github Gist with Composer, but sometimes you need to install code that isn't isn't even in a public facing VCS. I for instance wanted to use a library only distributed by Zip. It's actually fairly easy! In your composer.json file, you simply add a repositories section to the root. You will want to update the url section to point at the remote zip you intend to load, as well as updating the name an..

I just patched puppet-gluster and puppet-ipa to bring their infrastructure up to date with the current state of affairs… What’s new ? Better README's Rake syntax checking (fewer oopsies) CI (testing) with travis on git push (automatic testing for everyone) Use of .pmtignore to ignore files from puppet module packages (finally) Pushing modules to the forge with blacksmith (sweet!) This last point deserves another mention...

I've been using tmux for a while, and even though I didn't like it at first, now I'm in love with it. I'm mostly using it as a GNU Screen alternative, but I don't use some of its fancy features like tabs, mainly because my window manager takes care of multiple terminal windows for me.

Another article courtesy of the folks over at Gear Patrol, this time a photo essay after a trip to South Africa’s Sabi Sands Game Reserve. I spent three months in South Africa a number of years ago, and hours upon days trolling through an adjacent park (Kruger National Park, for those curious), but only managed to see a fraction of the sights the folks did here. Even then, though, I have no complaints: Africa was full of majesty everywhere ..

The recent surge in attention to searchcode from the Windows 9/10 naming fiasco resulted in a lot of questions being raised about searchcode’s policy about free software (open source). While the policy is laid out on the about page some have raised the issue of the ethics about using such a website which is not 100% free (as in freedom). For the purposes of the rest of this post “free software” is going to refer to software defined as n..

The first commandment that any young programmer learns is “Thou Shall Not Duplicate”. Thus instructed, whenever we see something that looks like it may be repeated code, we refactor. We create libraries and frameworks. But removing duplication doesn’t come for free. If I refactor some code so that instead of duplicating some logic in Class A and Class B, these classes share the logic in Class R (for reuse!). Now Classes A and B are indirect..

Burn me once, shame on you; burn me twice, though, shame on me: I’m hesitant to get behind Plastc given the apparently insurmountable challenges of this space, but that won’t stop me from wishing them success. At this point, I just wan..

In a day and age before ubiquitous personal drones roamed the skies, capturing incredible footage of active volcanoes, for example , filmmakers had no choice but to climb into planes and film those breathtaking views themselves. Harrison Sanborn found some of this footage in his father’s archives, digitized the film, and turned the result into a neat three minute video on Vimeo. There’s a certain quality to this footage that newer, digit..

An incredible, remarkably powerful story by Alan Heathcock that seeks to lay the harsh realities of drought to bear with a painful, hard-hitting story of good people who have lost everything for lack of one sample necessity: water.
