Some fun updates for vagrant hackers… I wanted to use the venerable clustered SSH (cssh) and screen with vagrant. I decided to expand on my vsftp script. First read: Vagrant on Fedora with libvirt and Vagrant vsftp and other tricks to get up to speed on the background information.

We shouldn’t really trust this kind of statistics, I know, but when my favorite language comes out as a clear winner, I can’t resist and take them for good. Python is the “language of the year” according to the PYPL index : it had the biggest increase in popularity share in 2013. PHP had the biggest decline. Meanwhile, Java continues to have the highest popularity share among the programming languages.

You’re so damn smart — I’ve told you how awesome I think you and the solutions you’ve built…they’re amazing. You have so many awesome things on your hard drive you built that it would blow the world away if only they knew. You created Facebook before there was Facebook and PayPal before there was PayPal. But recently I’ve heard you ask, “how can this junk software out there be so popular?”…why are all these idiots more successful than me?

Usually one might expect an article by an experienced polyglot speaking a dozen of languages when reading such a headline. But in this case, it’s just a German teenager who’s only fluent in German and English, while also learning Spanish and French.

Earlier this week Matt Gemmell posted Who to Read in 2014 , where he pointed out ten writers and explained why he felt everyone should pay attention to their work in the upcoming year. At the end of his post, after listing his five favorite articles from the last twelve months, he called on other writers to provide their version of this list. Never one to back down from a challenge, I have done so with a bit of a twist: in addition to th..

A collection of my favorite cabins from Cabin Porn and other similar sites, beginning with The Watershed . A seventy-square-foot building in the woods of Oregon specifically designed as a writer’s retreat, I love the idea of a small, designated area set apart in which to conduct one’s most personal work. Although given the type of articles I traditionally post I feel such an environment would not be particularly conducive to my writing, ..

The only thing I love more than listening to podcasts is writing about them. During the last curfuffle I wrote Podcasting State of the Union where I did my best to provide counterpoints for the flaws Harry Marks pointed out in the podcasting industry. To my delight, many agreed with me. After a few days the heat died down though, and I did not expect to have another opportunity to discuss this topic for a while. Then Ben Brooks ..

Maybe instead of Coder Dojos for kids, we should run them for their teachers. We must build a team of dedicated teachers to support school coding programs. We do not rely on our students to absorb math from textbooks, online videos or math clubs; similarly, we cannot depend on every student to learn to code on their own, by using online tutorials and afterschool clubs. If coding becomes as fundamental as reading and writing, we need to ..

Introduction There are lots of posts that talk about the internals of slices, but when it comes to maps, we are left in the dark. I was wondering why and then I found the code for maps and it all made sense. https://golang.org/src/runtime/hashmap.go At least for me, this code is complicated. That being said, I think we can create a macro view of how maps are structured and grow. This should explain why they are unordered, ef..

Prompted by an article Zach Epstein posted to BGR last Thursday titled Testing the ‘Apple tax’: What would it cost to build a Windows version of the new Mac Pro? I planned to link his piece as a smug counterpoint to all the people I know who like saying that they can build a more powerful machine for “1/3 the cost” 1 of my overpriced Apple computer. As I thought more about the notion of an Apple tax though, I realized I had more to s..

We’ve studied the Fourier transform quite a bit on this blog: with four primers and the Fast Fourier Transform algorithm under our belt, it’s about time we opened up our eyes to higher dimensions. Indeed, in the decades since Cooley & Tukey’s landmark paper, the most interesting applications of the discrete Fourier transform have occurred in dimensions greater than 1. But for all our work we haven’t yet discussed what it means to take an “n..

I don’t do a ton of Linux kernel development these days, but I’ve done a fair bit in the past, and picked up a number of useful techniques for doing kernel development in a relatively painless fashion. This blog post is a writeup of the tools and techniques I use when developing for the Linux kernel. Nothing I write here is “the one way” to do it, but this is a workflow I’ve found to work for me, that I hope others may find useful.

A very interesting read if you’re into Python. Eve has been Python 3 compatible for a while and honestl, I would be surprised to find that somebody is running it in production under Python 3. Why aren’t people using Python 3? First, I think it’s because of a lack of urgency. Many years ago, before I knew how to program, the decision to have Python 3 releases live in parallel to Python 2 releases was made. In retrospect this was a mist..

Number #3 on Praeclarum’s list hits home for me, but all his points are both valid and strong. As a programming language nerd I had mixed feelings when Jon Galloway tweeted about Microsoft’s new programming language. “Why are your feelings mixed?” I kept asking myself. I love new programming languages. I took an internship at Microsoft just so I could be closer to the people who made C#. I read language specs for fun. I write compiler..

He sat two offices down from me, but we never worked on anything together, never laid eyes on each other after 5 p.m. Our relationship consisted, in its entirety, of work-related small talk in the break room, his lunch rotating behind us in the microwave. Ding, stir, have a good rest of your day. via What Happens When One of Your Coworkers Dies | The Billfold.

In the past I have criticized Betaworks for bot..
