C# gives us an ability to use closures. This is a powerful tool that allows anonymous methods and lambda-functions to capture unbound variables in their lexical scope. And many programmers in .NET world like using closures very much, but only few of them understand how they really work. Let’s start with a simple sample: public void Run () { int e = 1 ; Foo ( x => x + e ); } Nothing ..

As a Dean for the technology faculties of a private college in Canada, I’m always looking to make our programs more aligned to the industry - my motto is: always look forward and never look back! However, when it comes to Information Technology (IT), I regularly find that the general perception of IT jobs is stuck in the past by at least a decade. I can’t tell you how many times I’ve met people who think that IT guys are stuck in the bac..

John Gruber, commenting on MG’s article : “I’ve harped on Amazon’s seemingly eternal lack of profitability as much as anyone, but when you think about it and study their business, it’s not that they can’t turn a profit. They’re not burning through money like they were in the go-go ’90s. They simply choose not to turn a profit, and instead invest everything in operations and low prices.” Mathew Alexander of One37.net and the popular pod....

Speaking of why I read John Gruber’s work , this kind of post, with this type of headline, is exactly why I read Daring Fireball: it made me laugh out loud, and showed me something I otherwise would not have come across. Good stuff. Permalink.

In software development, we solve problems. As we solve these problems, we build connections in our minds of how to look at a problem, relate it to previous problems and solutions, and re-apply past approaches and techniques. These behavior habits build dogmatic ways of thinking and limit design choices to selective technologies we’ve used in the past. As we all know, you have to continually learn new technologies and different ways of thin..

Here is a video interview of me talking about the origins of NoFlo , the flow-based programming environment for JavaScript: You’ve seen short pieces from this in the NoFlo Kickstarter video , but most of the material is new. This was shot when NoFlo turned two , and so I’m obviously spending some time talking about where things came from. The video should work well to support the hacker’s perspective of our funding campaign. Plea..

There are two particular sets of features that continue to keep me very excited about the momentum of Postgres. And while PostgreSQL has had some great momentum in the past few years these features may give it an entirely new pace all together. One is extensions, which is really its own category. Dimitri Fontaine was talking about doing a full series just on extensions, so here’s hoping he does so I dont have to :) One subset of extension....

Back in June, Gustavo Niemeyer posted the following question on his Labix.org blog: Assume uf is an unsigned integer with 64 bits that holds the IEEE-754 representation for a binary floating point number of that size. How can you tell if uf represents an integer number? I can't talk for you, but I write business applications. I just don't have the background to quickly knock out an answer for a question like this. ....

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.
