Figure 1: Sample screenshot editing my .vimrc Vim is an excellent text editor. I've used it for many years and like most vim users, have collected a fairly large collection of settings in my .vimrc and learned how to grok my vim usage effectively through a lot of trial and error. To that end, I've tried to assemble a useful overview of my experience with vim. Foreword: Why? Why would you want to even put in the effort to ....

From a certain version of the “jetty” package in Debian Linux, if the web application didn’t start up (servlet init() throws an Exception), this error wasn’t logged anywhere. The solution is to install the libjetty-extra package. sudo apt-get install libjetty-extra It took some amount of experimentation to find the solution. I don’t know why you’d ever want to not log errors; i.e. why the logging of errors is an “extra”.

Recently, Phil Robertson of the sensational cable TV program Duck Dynasty has drawn quite a bit of flack for his very Christian views kept largely hidden until now through A&E’s refusal to air his more candid statements. Setting personal opinions aside though and totally disregard the absurdity of crucifying Phil for his beliefs because today’s hyper-sensitive, disgustingly entitled society seeks to vilify everyone who challenges their nu..

When I joined college I was a pretty bad swimmer. During freshman year I took some beginner/intermediate swimming classes and learned proper swimming technique for stomach crawl, breaststroke and butterfly. The next year I saw this class called Master’s swimming, spoke to the coach and signed up for it. I was by far the weakest swimmer in the class. Everybody else had great stamina and technique. We would do series of 50 metres swimming f....

Well, One Game a Month is done! I’ve managed to complete 12 games for the year. My motivation by the end was lacking, so I took it kind of easy this month and made a very simple and quick game called Simon Says . Last month’s game, 9 to 5 , took much longer due to the number of art assets required. I’ll write a proper post about the challenge, how everything went, etc later.

Linkbait title aside. This is the story of a holiday card gone wrong because of Facebook's advertising rules. Backstory: I work at a co-working space in Washington, DC called Affinity Lab . This happened to one of my co-workers, Mike who works at a company called ISG. His company created a virtual holiday card and shared it on Facebook. It seems innocuous enough. In his words 'it's a no brainer to boost posts for $5, it goes from 10....

Python script to check last exec time and exit code of script

I needed a script that checks: whether a cronjob ran at its determined date (that means it runs regularly) if the cronjob ran successfully It should also be monitor-able via Nagios . That means, it should provide a meaningful output for when something went wrong with the cronjob, e.g. “ CRITICAL : cronjob did not run!” Of course, someone already had the same requirements and built a Perl-script for it, which in turn can be used as ....

Introduction The first thing I did when I started programming in Go was begin porting my Windows utilities classes and service frameworks over to Linux. This is what I did when I moved from C++ to C#. Thank goodness, I soon learned about Iron.IO and the services they offered. Then it hit me, if I wanted true scalability, I needed to start building worker tasks that could be queued to run anywhere at any time. It was not about how many..

I wrote a couple months back about exploring FDWs. Its become quite clear to me, despite still having ample room for improvement, they’re not getting enough attention. Foreign data wrappers are perhaps better thought of as a foreign table, or even better yet as a view into some remote data source. They don’t take care of auto-updating or syncing data, thats all up to you, but it gives you a straight forward mapping to work with remote data ....

Somewhere to Belong In a place the wind sways, Is a meadow to fritter away, Has a flower to hold tears, And a shade until the sky clears. Lives a heart to hide a hurt, In the saint of the heart.

Great news. Now, the only reason I have left to keep Apple’s Mail app around is for the occasional spam message, which Mailbox curiously does not have any way of handling. Once Mailbox builds that functionality in, I can happily say goodbye to Mail. Permalink.

Jim Dalrymple with his characteristically ambiguous thoughts regarding Nokia’s latest commercial, hot on the tails of Apple’s spectacular ad Misunderstood : “Kids, this is why you don’t do drugs while making a TV ad.” I normally wouldn’t have linked to such a thing as this, but it illustrates exactly why everyone devoted so much time and attention to Misunderstood when it came out: with such “competition”, how could we not?

Via Ben Brooks , Chrys Bader takes a very interesting look at where Facebook came from, its current state, and the platform’s bleak future. With the exception of Twitter I have all but abandoned social networks, including the venerable elder statesman Facebook, so I rarely take any interest in articles examining them. I followed Ben’s link on a whim though, and I’m very glad I did. Especially damning, I thought, was his comparison of Fac..

The TestNG Eclipse plugin has a feature that will convert your unit tests from JUnit to TestNG in a few simple clicks, and it works pretty well for the most part. However, I soon noticed that it was replacing Assert.assertX with AssertJUnit.assertX. Upon further inspection, this was because TestNG’s Assert uses different argument ordering. For example // JUnit Assert.assertEquals(message, expected, actual); // TestNG Assert.assertEquals(..

I rarely find anything worthwhile on Hacker News — primarily interesting coding projects and the latest NSA story to catch the masses’ attention, rarely anything substantive — but when I do come across something interesting it really is truly exceptional. This article from Benjamin Bratton is one of those excellent pieces, one for the record books. I can’t wait to watch his talk. Permalink.

Four weeks old today and I have yet to at least mention Shawn Blanc’s The Sweet Setup . For the three people who still have not visited this site, The Sweet Setup collects and reviews best-in-class apps for iOS and OS X alike, with a special focus on interviewing “internet celebrities” to discuss their home and mobile computing setups. So far, Shawn Blanc and his impressive staff have conducted six of these interviews . As a recent Ma..

Having updated his article on Apple’s latest ad , Ben Thompson finally delved in to the reason so many fell in love with this commercial in the first place, and the reason so many have talked about it. As I said earlier this video hits so close to home because it does not focus on feature comparisons or implausible situations necessitating eighteen processors, but instead on the experiences Apple’s devices enable: Permalink.

With the release of Go 1.2, slices gained the ability to specify the capacity when performing a slicing operation. This doesn’t mean we can use this index to extend the capacity of the underlying array. It means we can create a new slice whose capacity is restricted. Restricting the capacity provides a level of protection to the underlying array and gives us more control over append operations. Here are the release notes and design d..

I am also re-watching Strang's linear algebra videos (currently at the LU factorization). Watched half of the lectures about 2.5 years ago, then school started and actually took a linear algbera class that semester (we used Axler's "linear algebra done right"). Two years on, re-watching Strang's videos and seeing the abstract ideas of Axler's textbook being played out concretely in terms of computation and matrices - it's amazing! I can now..

A lot of people have combined a RasPi and a SDR dongle to get a low power consumption ADS-B tracker. Tomasz Miklas has created an image for the Raspberry Pi, that has everything that is needed to run your own aircraft tracking "service" already set up. I've finally had a chance to experiment with it and this will be my short review.

Last night I took Coin to task for extending their pre-order sale, again, in to the new year rather than allowing it to expire as should have happened sometime today. I briefly explained how this move has further devalued their product by virtually solidifying it at the $50 price point, and then talked about how Coin’s latest escapade showed a startling lack of respect for the individuals who put their hard-earned cash on the line so that..

I feel a bit like a broken record at this point, what with having already talked about Coin twice before , but the company’s latest stunt bears once again picking up my banner and going back off to war: earlier this evening, via their Twitter account, Coin posted a “BREAKING NEWS!” announcement that — you guessed it — extended the $50 off early adopter deal into the new year. Surprised? You should’t be. Permalink.
