If you find yourself interviewing for a software engineering position today, you can be 90 percent sure that you will be asked to solve some programming puzzles. We’ve all been there. You come to the office for an interview, spend a few minutes talking about the job and you, and then the inevitable hits: programming puzzles and quizzes. You are asked to solve nonsensical, irrelevant, theoretical problems on the spot while the interviewe....

I've always been a proponent of the "right tool for the job" approach to programming. Different languages are well suited for different situations. Over the past 2 years I've spent a great deal of time with Ruby on Rails after coming from a background of PHP, Java and Perl. Here's how I got started and some of the lessons I learned along the way.

Speaking of Cabin Porn , the folks over at the site have put a lot of work in to finding and posting great pictures lately, as well as polishing the site’s design over the past few months. And while it may not be new, for I actually can’t remember if it was there or not before today, I wanted to take a minute to mention the Cabin Porn Archive , where you can find every post going all the way back to February of 2009. Having just discovered..

Seeing pictures like this one remind me of all the times I looked at a hill and thought about how awesome it would be to grab a shovel and dig a house out of it, similar to the way Sean Hellfritsch and Rob Wilson built their subterranean breakfast nook , but more like this stone cellar in Newfoundland.

I knew this would happen. Out of all of the new things that I have to learn to do for this snail game, the part that is the most tedious and difficult for me is the UI. Every part of the UI. You’d think that I’d be able to use web design skills from my previous life to make this at least a little intuitive, but nope - this blows. And it’s not just designing the thing that’s the problem, it’s finding the best way to implement it, too.

The idea of a Nintendo phone, initially proposed by Moises Chiullan and Horace Dediu on episode eighty-three of The Critical Path, has continued to gain traction in my mind since I listened to The Analyst Taxonomy . As Moises pointed out in the tail end of the show Nintendo, like Apple, possesses the capability to not only manufacture physical devices, but to create the software necessary to run them as well.

I recently needed to convert some Apple Lossless music files to FLAC . Here’s how to do it: If you don’t already have ffmpeg or libav-tools installed, do this: $ sudo apt-get install libav-tools Then run this to do the conversion, in the folder with music in: $ for f in * .m4a ; do avconv -i " $f " " ${ f %.m4a } .flac" ; done And that’s it - it will convert all the .m4a files in that folder to..

Shortly after Merlin Mann posted Chasing the Right Zero I linked to the article , as did most of the internet. With Chasing the Right Zero , Merlin wrote the article I had had simmering on the back burner for months, putting to words my epiphany regarding Inbox Zero and the real meaning behind the philosophy. At the time I felt no need to add anything to his words or quantify my own opinions on the subject, so my linked list post cont..

In HTML applications, jQuery has changed the way people thing about view rendering. Instead of an input or a text field in the view pulling data into it, the jQuery code pushes data into the view. How could this look in a server side situation like Java? In this code example, I read an HTML template file from the classpath, set the value of an input field and append more data based on a template (also in the HTML file).

I was meant to write this blog post four hours ago. Instead I got home and decided that since this one would have quite a bit of pictures in it and I’ve been running into bandwidth issues I may as well find a better solution for image hosting (as opposed to uploading everything to this server). I signed up to Amazon S3 on its free trial account and have been attempting to set it up ever since. Now I don’t even want to write this stupid po..

In this post we’ll get a quick look at two ways to define a category as a type in ML. The first way will be completely trivial: we’ll just write it as a tuple of functions. The second will involve the terribly-named “functor” expression in ML, which allows one to give a bit more structure on data types. The reader unfamiliar with the ML programming language should consult our earlier primer.

Figure 1. Just hold down your chosen compose key, then press the other keys in turn: [compose key] + e + = gets you a Euro symbol. The compose key on Linux is incredibly useful, but not configured by default - and on XFCE there’s currently no graphical UI to change it. However, it’s pretty simple to change… here’s how to make the Caps Lock key your compose key: In the file /etc/default/keyboard, change XKBOPTIONS to look like this....

This was a difficult piece for me to write because my feelings regarding academic writing are so conflicting. On the one hand, I view academic writing — by which I mean the type of writing taught in American schools — as a certain boon: it introduces kids to the writer’s craft, teaches young writers how to write, and provides an introduction to organizing and conveying thoughts and ideas in a coherent and orderly fashion. On the other hand ..

Allan McRae , Pacman developer, found an interesting small tool, called Distro Picker . This tool finds the Linux-Distribution based on what you prefer as a Desktop Environment, Package Manager and other settings. When I tried it out, it offered me my current distro: Arch Linux , so interestingly, it works really well! I’ll definitely have to take a look at the other distros offered.

I figured I’d put together a list of the main features I need to finish for A Game of Snails. If anything, it’ll help me gather my thoughts and track my progress better as well as helping me figure out what to work on next. What I should be doing is compiling specs properly for this, but I’ve been too preoccupied with actually working on the thing to keep up with the documentation. Not to mention this game has been in my head for so long (7..

Virtually every time Dan Benjamin is interviewed, the host eventually asks the same question posed by numerous interviewers of days gone by: “When people ask what you do, what do you tell them?” And every time, Dan answers the same way, saying that his answer depends on the person asking. For some, Dan responds that he is in broadcasting and leaves it at that; in other cases he goes in to more detail, qualifying that statement by describing..

Two interesting anecdotes showing a different, less praiseworthy side of Steve Jobs. The man was not perfect, as many purported him to be in the sad hours following his death, but a mere mortal not just like the rest of us, but human nonetheless. “He made himself so fearful and terrible that an entire group of amazing, talented, hard working people, ended up getting screamed at wrongfully. It was his fault that the MobileMe launch went ..

This isn’t going to be a huge world changing ecosystem, but there is room for one little monster to take it all.” Although I feel Alex Kessinger’s numbers would have benefited from some more research and the methods used to obtain his eventual conclusion could use some polish, his estimate seems to at least be in the ballpark of probability, as does his conclusion.

After reading this article, I went back and forth trying to decide whether or not I should link to it. The piece was not particularly remarkable in any way, after all. Regardless of how I justified not writing about it though, I kept coming back to this story until I eventually gave in. It’s a touching story tinged with the melancholy undertone of existential ennui. Having spent months away from home multiple times in the past, I can empath..

In the past I have written one article about women and equality, A Crying Shame . I am quite proud of that article. So much so, in fact, that unlike many of the other topics I rehash here, I have felt no need to write anything more on the subject. I did feel pushed to at least mention the article linked at the head of this post, however, especially after listening to what I seem to recall was episode #114 of Back to Work a few weeks ago.....

When I first came across this article a few weeks ago while browsing Less Wrong, Eliezer Yudkowsky’s chronicle struck me as the perfect example illustrating the importance of a number of different things, primary of which was the significance of asking the right question.

In the mid-1800s, there were thousands of unique varieties of apples in the United States, some of the most astounding diversity ever developed in a food crop. Then industrial agriculture crushed that world. The apple industry settled on a handful of varieties to promote worldwide, and the rest were forgotten. They became commercially extinct — but not quite biologically extinct.” A nice change of pace from the usual; a delightful article..
