A few years ago when I decided to start exploring the world of PC gaming, I set out with three criteria: it could not, like major titles such as Call of Duty or Ghost Recon, require a significant amount of capital just for the the privilege of participating in this hobby. Whatever I ended up choosing had to have a low price tag or, preferably, cost nothing at all. Further, my distraction of choice had to run well on a mediocre machine: I re....

Among the many compelling talks that attendees come to expect every year at the Strange Loop conference was a session given by Ben Johnson that provided an overview of a new distributed consensus protocol originating from research at Stanford University, named Raft. What is distributed consensus? Distributed consensus can be described as the act of reaching agreement among a collection of machines cooperating to solve a problem. With the ri..

For the past year, every Wednesday night at about 6:00 p.m. work stops! Since I have been working for Levers there has been a weekly hack night.

A few awesome readers have posted comments in Computing Homology to the effect of, “Your code is not quite correct!” And they’re right! Despite the almost year since that post’s publication, I haven’t bothered to test it for more complicated simplicial complexes, or even the basic edge cases! When I posted it the mathematics just felt so solid to me that it had to be right (the irony is rich, I know).

A small and simple feature you can immediately add to your Android application is the functionality of maintaining the ListView position. When your user switches to a different Activity/Screen and then back to the ListView, they will not have to scroll through the ListView items again to get back to where they were. Android Studio (as well as Eclipse) offers a few nice default templates via ADT to get you started with your application....

Hat-tip to Shawn Blanc for the original link , former hedge-fund manager Sam Polk talks about his amazing journey from addict college dropout to making nearly four million dollars in a single bonus, to say nothing of his base salary and any other dividends accrued throughout the year. If you, like me and so many others, have ever thought, “If I could just win the lottery, think of all the great things I could do; all the problems that mone..

Before Benjamin Bratton posted the transcript and then full video of his TEDx talk titled “ We need to talk about TED ”, I cannot remember ever seeing anyone seriously criticize this group. Now, though, it seems not a week goes by without someone taking a particular speaker or the entire conference to task for some harebrained, far-fetched, and implausible scheme that somehow made it to this once-revered stage. Oh, how the mighty have falle..

We use CentOS VMs at work to emulate our production environment - and it took me a while to figure out how to get the VirtualBox Guest Additions to build reliably on CentOS 6.4/5. This is what I’ve currently settled on as a reliable method. First, make sure that you’ve got the kernel headers and tools installed that you need to build stuff: $ sudo yum update -y $ sudo yum install gcc kernel-devel kernel-headers dkms make....

I changed my blogging platform from Wordpress to Pelican . Pelican is a static html generator written in Python. I also changed the whole design. It’s a bootstrap-theme with some little modifications. The reason I changed from Wordpress is the effort to maintain a secure and up-to-date installation opposed to static html files with only minimal Javascript. Also there’s no need for me to use a full fledged CMS like Wordpress when al..

So after about two years of preferring CoffeeScript for my application code, I'm switching back to JavaScript. Here are some thoughts on my experience. Why I Am Switching Back So in winter 2011, given my personal situation and skillset, the cost/benefit equation for CoffeeScript was an overall positive. What I have found is that in the intervening two years, the equation has reversed to be an overall negative for CoffeeScript. So that's w....

As detailed in The Curse of Preconceived Notions , before Monday night I had not read any of Joe Rosensteel’s work; instead, I had wrongly disregarded it in any capacity surpassing that of humorous entertainment. When I finally came to my senses and started reading his blog though, starting with The Ubiquitous Yak for the Discerning Obsessive , I found that I really enjoy his thoughts and opinions. So for anyone else that, like me, ma..

Although we arguably found product/market fit, we couldn’t quite crack the business side of things. via Chris Hates Writing • Today my startup failed .

They include our monthly challenges and hiring challenges. There were over 200 internal and public contests by colleges in the previous year.

This post is intended to be a tutorial on how to access the RealityMining dataset using Python (because who likes Matlab?), and a rant on how annoying the process was to figure out. RealityMining is a dataset of smart-phone data logs from a group of about one hundred MIT students over the course of a year. The data includes communication and cell tower data, the latter being recorded every time a signal changes from one tower to the next.

I listened to every episode of The B&B Podcast back when Shawn Blanc and Ben Brooks recorded it once a week up until just shy of a year ago. It came as a great disappointment, then, when it ended rather abruptly. Thankfully, I did not have to go without for long: today, Shawn announced a new weekly show to be released alongside his members-only Shawn Today podcast. I already subscribed, and I recommend you do as well: if The Weekly Brief ..

An interesting conversation ensued in which many weighed in both for and against. I did not, howe..

Until yesterday, every time someone mentioned Joe Steel or his blog , I immediately thought of Terrible Podcast Screenplays . I had equated Joe to this one Tumblr, and that humorous pursuit to Joe. In my mind, they were one and the same. As a result, whenever someone referred to his work, I absentmindedly categorized it as comedic and of little value beyond a source of entertainment, and disregarded it accordingly. Late last night though,..

But, it was not exactly possible to watch it as seamlessly as a movie until now. Today, we are announcing the release of HackerEarth’s CodePlayer that exactly does....

When Sid O’Neill posted Farewell to Text Files , I read his article but really had nothing to say on the topic. One person left the world of plain text files — “so what?”, as Dan and Merlin love saying. But Joe Steele’s response, cited above, made me reconsider Sid’s predicament: the low barrier to entry plain text afforded him made testing new writing apps too easy to resist, and so Sid spent more time experimenting than working. At som..
