The slight tickle off the face, The fierce knock in subtle grace, The quickest rumble in the race, The enemies did, bow and brace. The wildest tornado in the calmest sea, The orbs of fire in a gentle spree, The lord of wind in the mountain’s lee, The knights did, scrum yet flee.

In Go values that are returned from functions are passed by value. Go gives you some nice flexibility when it comes to returning values from a function. Here is a simple example of returning two values from a function: package main import ( "fmt" ) func main() { id, err := ReturnId() if err != nil { fmt.Printf("ERROR: %s", err) return } fmt.Printf("Id: %d\n", id) } ....

A few days ago I watched a strange article from The Verge titled LG starts producing curved displays to cure dull phone design scroll by in my RSS reader, but paid it little attention. Then, last night, another item caught my eye: Is this Samsung’s curved smartphone? Although still unconvinced as to the form factor’s upsides, I nevertheless opened the article. Shortly thereafter, to my delight, the last piece confirmed the rumor: ..

I recently read The Git Book. As I went through the Git Internals parts, it struck me how simple and elegant the structure of Git really is. I decided that I just had to create my own little library to work with Git repositories (as you do). I call the result Silly Jgit. In this article, I will be walking through the code. This article is for you if you want to understand Git a bit deeper or perhaps even want to work directly with a Git rep..

As a huge fan of the medium myself, over the last two weeks I have followed a burgeoning discussion on the podcasting industry with great interest. Across the board, the discourse has remained almost universally positive: Stephen Hacket , Chris Gonzales , Federico Viticci , and Myke Hurley have all expressed considerable enthusiasm for the changes iOS 7 in particular signals for this space, and great hope for its future. Unsurprisingly..

I received a question about ALTER SYSTEM in the comments section of another blog post recently. The question was that while ALTER SESSION SET EVENTS ‘10046 … ‘ enabled the SQL Trace for the current session immediately, ALTER SYSTEM on the other hand didn’t seem to do anything at all for other sessions in the instance. There’s an important difference in the behavior of ALTER SYSTEM when changing paramters vs. setting events. For ....

MySQL - Primary data store At HackerEarth , we use MySQL database as the primary data store. We have experimented with a few NoSQL databases on the way, but the results have been largely unsatisfactory. The distributed databases like MongoDB or CouchDB aren’t very scalable or stable. Right now, our status monitoring services use RethinkDB for storing the data in JSON format and that’s all for the NoSQL database usage right now. With ....

I learned very quickly while working on a large open source project is that it is important to make my code hard to break. The primary line of defense for this is a comprehensive test suite, but I think it’s also very important to create functions that are easy to use and difficult to damage. I find I even code this way on personal projects that will never be released. Even if you never work on a team with other developers, there is a g..

As a rule I try not to link an article unless I have something meaningful to add to the surrounding conversation, and especially in cases where all the popular tech sites have already picked up said article. Occasionally, in exceptional circumstances I break that rule however, as I couldn’t help but link Fred Vogelstein’s New York Times piece chronicling the advent of the first iPhone. An exceptional read, to put it lightly. Permalink.

Non-deterministic unit tests are like kryptonite for an automated build. They cause intermittent build failures and the development team becomes accustomed to ignoring a failing build. This is a Bad Thing. Thread.sleep(x) in a unit test is a recipe for non-deterministic behaviour. Think about what happens when this test is run on a slow machine. How big does X need to be? I often see this anti-pattern in multi-threaded code where the te..

Exactly a week ago today Chris Gonzales of Unretrofied wrote an article called iOS 7 and the State of Podcast Apps , a rather presumptuous title given the article’s actual contents, that I initially did not plan on linking to or writing anything about. At the very bottom of his article though, Chris tacked on a bracket-thetical that gave me pause: Permalink.

Over the last few weeks, as I scrolled through my RSS reader and came across a particularly interesting or attractive cabin, I would send the page to Instapaper. Unfortunately, most of those cabins got lost in translation, so to speak, and never made it to this site for one reason or another. I’m not here to assign blame though, but instead to show off some really great cabins. Permalink.

To be honest, I really didn’t want to do another BlackBerry-related post. It just doesn’t feel like something that interests me anymore. But today I decided to do one anyways for several reasons: I’ve been a long-time BlackBerry user and author of their academic textbooks - as a result, I know their technology inside-out, and have worked closely with the organization. I have lived and taught computer science in the K-W region for..

In rolling out our real time bidding infrastructure, we were faced with the task of syncing data for every user we could possibly target across four regions. We have on the order of hundreds of millions of users, and tens of thousands of writes per second. Not only do we have to deal with the daunting task of writing this data out in real time, the bidding system has a hard cap of 100ms for every bid request, so we need strong guarantees ....

Introduction In my post about building and running programs in Iron.Io , I needed to switched over to my Ubuntu VM to build linux versions of my test programs locally. I love the ability to have Ubuntu available to me for building and testing my code. However, if I can stay on the Mac side it is better. I have wanted to learn how to cross compile my Go programs for the two platforms I use, darwin/amd64 and linux/amd64. This way I ....

A lot of people who like functional programming often give the reason that the functional style is simply more elegant than the imperative style. When compelled or inspired to explain (as I did in my old post, How I Learned to Love Functional Programming), they often point to the three “higher-order” functions map, fold, and filter, as providing a unifying framework for writing and reasoning about programs. But how unifying are they, really..

Anybody that has worked with AWS must deal with the arbitrary hostnames that AWS generates for each instance. These names are difficult to remember and not particularly useful to understand what tasks any particular node is assigned to. The classic solution to this problem is to use a DNS server, but unfortunately setting up and maintaining a DNS system can be a pain and, when you are a quickly moving startup, it’s a lot easier to spend....
