The University of Iowa Libraries is home to the Fluxus West Collection, a group of physical art objects made by artists Joseph Beuys, Yoko Ono, George Brecht, Alison Knowles, Ken Friedman, A-Yo, George Maciunas, and others. In early 2012, I developed this 3D visualization system based on curation from Stephen Voyce, assistant professor of […]

For the last 2 months, we’ve been using ControlTier to automate deployments to our integration and QA environments. Our deployment is a little more complicated that most Java applications because it runs on a pseudo-grid. That is, there are 2 clustered JBoss servers, a database server, and 4+ Linux servers that each run about 8 Java processes. I was able to get ControlTier up and running in a few days, and defining the jobs was relati..

Recently I won a Kindle Fire in a Hacker Buddy give away, sponsored by Tokbox. (Hacker Buddy is a site that connects hackers to other hackers with the goal of helping each other out, you should check it out) I wanted to write up a summary of my experience using the device. I'm not going to bore anybody with specs, information or detail. Enough information can be found online, eg. on the Amazon Kindle store.

Finding Bigger Numbers, a Measure of Human Intellectual Progress Before we get into the nitty gritty mathematics, I’d like to mirror the philosophical and historical insights that one can draw from the study of large numbers. That may seem odd at first. What does one even mean by “studying” a large number? Of course, I don’t mean we stare at the number 1,000,000,000,000, which is quite large, and wonder how mankind can benefit from its elus..

I’ve just registed for five Saturday (early Sunday in Perth) sessions of the AltDevConf online conference. Four from the Design and Production track and one from the Programming track. I haven’t been following AltDevBlogADay for too long so not sure what to expect, but I’m sure I’ll learn some awesome stuff along the way.

I’ve recently set something aside for a scheduled “breather”. It wasn’t anything related to anything I’ve talked about here before, but has been taking up a lot of my time - I’ve been forcing myself to not think about anything else (in terms of out of work things) too much until it’s done to not get distracted. It’s been easier than I thought - usually I can’t stop thinking about all the potential things I’d love to learn to make, but tunne..

This post assumes familiarity with some basic concepts in complex analysis, including continuity and entire (everywhere complex-differentiable) functions. This is likely the simplest proof of the theorem (at least, among those that this author has seen), although it stands on the shoulders of a highly nontrivial theorem. The fundamental theorem of algebra has quite a few number of proofs (enough to fill a book!). In fact, it seems a new too..

I had so much pain to make it work so here is how to have a ZFS root with a raidz pool on 5 disks, specially with OVH without any console or kvm to debug the boot process. The server has 5 disks that I put in raidz and boot on it, but this should apply to most installation. gpart destroy -F ada0 gpart destroy -F ada1 gpart destroy -F ada2 gpart destroy -F ada3 gpart destroy -F ada4 gpart create -s gpt ada0 gpart create -s gpt ada1 gpart cre....

Arguably, CapsLock is the most useless key on your keyboard. I honestly can’t remember the last time I had a real use for it. If are a programmer, you should remap it to something more useful. The rest of this post will describe how to remap your CapsLock on a Mac OSX installation. What we are going to do I’m a heavy vim user and reaching for the Esc key all the is a pain. We will remap the CapsLock to Esc. However, I want to be able to....

When I started searchco.de the amount of hardware required was fairly low. I did a lot of processing on other machines and pushed the results through allowing the machine that serves the site to just focus on the job of delivering results. The result was everything was running on a nice VPS provided by Atum.com 2.9 Ghz CPU 512 MB ram and about 30 GB of hard disk space. This was more then enough to support the index I had and do everything r..

While on the sofa today, I started having a play around with some GUI improvements in the app. It’s still a fair way from release but I wanted to release a version to get opinions on on the changes. I’d also like to open the floor for feature requests for the next release, so if there is something you want (that isn’t video’s) put it in the comments and I’ll try and get it into the next beta!

When deploying a Django application, you often use a requirements.txt file that contains a list of the application’s dependencies. During deployment, your provisioning system will pip install all of those to make sure that your application runs as desired. The format of a typical requirements.txt files isn’t unlike the following django==1.3.1 psycopg2==2.4.4 Fabric==1.3.3 ... By default, pip will go to the Python Package Index (PyPI) ....

This post is the third post in a series on computing with natural language data sets. For the first two posts, see the relevant section of our main content page. A Childish Bit of Fun In this post, we focus on the problem of decoding substitution ciphers. First, we’ll describe a few techniques humans use to crack ciphers. We’ll find these unsatisfactory, and move on to a simplistic algorithm which does a local search on the space of all pos..

Una REST API che adatta le sue risposte al MIME Media-Type delle richieste HTTP

Da qualche tempo sto lavorando alla implementazione di una REST API. In linea generale e semplificando, una API è un servizio che espone alcune funzionalità, è accessibile via internet più o meno liberamente ed è, infine, utilizzabile non solo da persone fisiche ma anche e soprattutto da altre applicazioni. Un esempio di API è quella di Facebook, che consente a chiunque di creare applicazioni che interagiscono con gli utenti e le pagine Fac....

This is not The Greatest Website in the World, no. This is just a tribute. I was approached by Tenacious D a week ago with an incredible quest: raising a phallus shaped phoenix onto the internet (oh and the first clip of audio from their new record.) How could I raise this majestic beast with the power of SoundCloud’s legendary API? The answer was simple: Have the sound itself rize the phoenix from its ashes.
