This is one of the coolest and important thing we recently built at HackerEarth. What’s so cool about it? Just have a little patience, you will soon find out. But make sure you read till the end :) I will try to make this post as resourceful, and clear so that people who always wondered how to implement a Continuous Deployment System(CDS) can gain insights. At HackerEarth, we iterate over our product quickly and roll out new feat....

Randall Munroe’s web comic XKCD has long been known for pushing boundaries in strange ways, but his latest experiment topped them all. Over the course of four months, ”Time“ grew as a frame was added every 30 minutes or so, ending up with over 3,000 individual frames by the time it wrapped up earlier this week.” I absolutely love XKCD. I have read every one of Randall Munroe’s 1246 comics, and Time — which you can watch in its entirety ..

That is the very reason Android has no Gruber-like figure - they have no central philosophy that would allow such a figure to emerge. What would the Android Gruber write about? There are of course Android writers out there, but they mostly cover the latest greatest phone or compare feature sets. They never really put things into context with the overall philosophy of the platform like Gruber does with Apple, because there is no overall phil....

This has nothing to do with politics, or gender. I know women who have been threated physically because of their thoughts on real-time strategy games. I knew men who had their spouses and children threatened, or had racial or sexual harassment thrown their way, because of review scores. This isn’t new. This isn’t rare. And it’s not something anyone can easily ignore, or something they should expected to endure silently and gracefully.” - Be..

It was time to take the plunge and upgrade from Fedora 18 to Fedora 19. Fedora 18 was one of the worst releases ever , so I figured it could only get better. I ran my backups as usual, however this time I didn’t seem to need them, the upgrade process went off without a hitch! I used the fedup-cli process over the network. I always run these things inside of screen.

I just published an article looking at the impact of the major outage that occurred yesterday (August 2, 2013) when EIG's Provo, UT datacenter failed. I also predict what to expect based on previous major outages. There was definitely a major spike in data produced and I got down to analyzing it.

Mostly as a self reference here is an extremely clean data access pattern possible using C# and Entity Framework. It saves you the effort of mocking the database context as the code you end up writing is so simple it is all compile time checked. Essentially you define a very simple class which provides a single method for getting data (although you may want a save data method too) and make sure you add an interface to make unit testing/mo..

This is the blog form of the Thinking in MapReduce talk at StampedeCon 2013. I’ve linked to existing resources for some items discussed in the talk, but the structure and major points are here. We programmers have had it pretty good over the years. In almost all cases, hardware scaled up faster than data size and complexity. Unfortunately, this is changing for many of us. Moore’s Law has taken on a new direction; we gain power with parallel..

Back in February , I gave a presentation on Discourse and client side MVC at TechTalksTO. It wasn’t recorded, but I’ve taken the liberty of creating a video version of the presentation with an audio track. While the presentation is about Browser Applications, I take a large detour in the beginning to talk about Discourse and Forum software in general. Enjoy!

Just a few days ago I was surprised by what someone was doing with their database, and not in the typical horrifying travesty against mankind. Rather, it was a feature that while familiar with I’d never seen anyone fully take proper advantage of - COMMENT or describing tables. Postgres has a nice facility for you to provide a description for just about anything: Table Column Function Schema View Index Etc. The specific use case was a da....

Interestingly it seems that Matt Well’s search engine Gigablast has been acquired by Yippy.com [ 1 ] 1 [ 2 ] 2 [ 3 ] 3 ( demo here http://demo.yippy.com/ ). Gigablast has always been one of my favorite search engines simply because it is so interesting. Started by a single guy, with an interesting blog and being one of the last true new indexes of the web it was always worth a look. While its sad to see it go this way I am happy that Mat..

The guys at Mailgun are taking a very interesting approach at the ever-lasting problem of proper Email validation: Given an arbitrary address this service validates address based off syntax checks (RFC defined grammar), DNS validation, spell checks, and if available, Email ServiceProvider (ESP) specific local-part grammar. They’re relying on formal grammar and not on regex like the rest of us, which is perhaps the more intriguing asp..

This article was written for and published by Safari Books Online Back in May, I finally decided that it was time to move away from the Microsoft stack to Linux. The cost of developing, licensing, and purchasing cloud computing on the Microsoft stack is too expensive. My company was approved for BizSpark, which made development possible for a small company like mine, but what am I going to do three years from now? My other problem is ....

For some reason (I can’t really put a finger on it exactly), I like to keep my servers up-to-date. I know! All those security patches, all those new features– they’re a killer! In all seriousness, I host several websites on a Mirabox from right behind my TV. I hopped on the plug computing train way back when the SheevaPlug was just a dev kit, and I’ve been on it ever since.

I'm a huge fan of Git. Used properly, Git's branching system can be immensely powerful. In fact, it forms a core part of our engineering workflow at the office. By providing a healthy degree of isolation between different changes to the codebase, we can provide QA with a clean way to test various change sets in total isolation before we produce a release candidate. This sounds rather nice until the realization that after we finally get a re..

This has caused a passionate debate a....
