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.

Motivation Pair programming is pretty common around Square , and I’ve had the fortunate experience of pairing with my manager, Xavier . Now, if (you have a Mac and) you’ve ever had to type in a different language, you know that there is a flag in the top right corner that signifies the layout.

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 article was written for and published by Safari Books Online If you read my article titled Analyze Data With MongoDB and Go, then you will understand the context of this debate with the idea of open source. That article talks about an application we are building, and it publishes some of the proprietary data we are gathering. It also shows techniques we are using to perform the data analysis. This has caused a passionate debate a....

In the documentation provided by the Go language team you will find great information on pointers and memory allocation. Here is a link to that documentation: http://golang.org/doc/faq#Pointers We need to start with the understanding that all variables contain a value. Based on the type that variable represents will determine how we can use it to manipulate the memory it contains. Read this post to learn more: Understanding T..

Most significant features are probably the native support for MongoDB write concern settings, new event hooks allowing for transformation of documents before they are sent to clients, increased handling of both pagination and CORS, and the native validation of float data types.

Both Burn Notice and NCIS, arguably two of USA Network’s most popular television broadcasts, adhere to a strict rule set in each and every episode: a sailor dies, the NCIS team responds and eventually solves the case, and in the last few minutes the overarching story progresses ever so slightly. Similarly, Burn Notice opens with the client, someone with a problem that Michael will agree to solve after a varying amount of reluctance, and clo..

For the month of August I am porting Interdiction to Android using CocoonJS. The AI is far from perfect right now, but it works. I am going to keep improving it. For now, however, Android port it is. If I’m lucky I can get it all ported before this year’s js13kGames challenge starts mid-month. If that’s the case I may participate in that and release that game as the September One Game a Month project, but we’ll see.

In ORM is an anti-pattern Laurie Voss concentrates everything I’ve been saying on the ORM plague in all these years. If your project really does not need any relational data features, then ORM will work perfectly for you, but then you have a different problem: you’re using the wrong datastore. The overhead of a relational datastore is enormous; this is a large part of why NoSQL data stores are so much faster. If your data is relational,..

Problem: Prove that for vectors $ v, w$ in an inner product space, the inequality $$\displaystyle |\left \langle v, w \right \rangle | \leq \| v \| \| w \|$$ Solution: There is an elementary proof of the Cauchy-Schwarz inequality (see the Wikipedia article), and this proof is essentially the same. What makes this proof stand out is its insightful technique, which I first read about on Terry Tao’s blog. He calls it “textbook,” and maybe it i..
