In Stanislaw Lem’s His Master’s Voice , humanity receives a “letter from the stars,” in the form of regularly repeating binary data encoded in a beam of extraterrestrial neutrinos. The protagonists know nothing a priori about the content of the letter. The plot unfolds as the message slowly, as a result of careful study, yields a few (not many) of the signal’s secrets. What would you do if you received such a dataset? How would you ....

I got into an ironic conversation the other day over the usefulness of having multiple languages in the world. I am of the opinion that languages are redundant and they only exist for being the most usable mechanism we have invented for communication so far.

I ask this question every time I open the app: What happened to Instapaper? After its sale both Marco and Betaworks seemed so enthusiastic about the popular read later service’s future. Since then two months have gone by without a peep from anyone — not even a point release. Permalink.

I hate the word “sexting” — I really do. It sounds as if a sixth-grader invented it in jest and whose parents, upon overhearing it, decided to apply it as the label for the act of sending lewd pictures on a mobile device. Or maybe the fated decision was left to a lonely man in the poorly-lit corner cubicle, laboring under a flickering fluorescent light: “Texting and sex... ‘Tex’? No, that’s not it. ‘Sex texting’? Too long. Ha, that’s what s..

Of course as soon as people realized this then the common comes a question, is hstore or JSON better. Which do I use and in what cases.

Speaking of app redesigns , Nevan Mrgan tweeted a screenshot of an app he was in the process of redesigning for iOS 7. Unlike Instacast 4’s mockups, this one looks like it will fit right in. Permalink.

Two days ago Betaworks — creator of the popular iOS game Dots, the company behind Digg’s rise back to fame, and proud owner of Instapaper — opened Digg Reader to the public after greatly accelerating its development following the announcement of Google Reader’s impending demise. Especially for a product upon which work was not schedule to begin until the end of this year, Digg Reader is a very impressive entrant into the RSS reader market. ..

plupload image Image from drupal.org . When building websites, we use a lot of smoke-and-mirrors to get things accomplished, and we often do it by re-purposing preexisting functionality and code. Once the page is themed, who will be the wiser, right? Unfortunately, a seemingly straightforward idea can become unwieldy when you are unfamiliar with the underlying APIs involved.

Yup - I woke up Saturday to find the message above when I visited my website. I’ve used Primus (Planet Domain) for the past 8 years as a hosting provider, and I’ve never had any issues whatsoever - including reaching my bandwidth cap. For starters, I was a little concerned, so I logged into my cpanel and checked out the AWSTATS first: Holy crap! Did I just get too much traffic this month?

My June One Game a Month project is called Interdiction . It’s a two player board game based on Tic-Tac-Toe, but with a twist. The goal of the game is to get a higher score than your opponent. Placing five of your tiles in a row grants you ten bonus points and usually, but not always, results in a win. However, it’s technically possible for a player to get enough points to win the match even if they aren’t the ones to finish the game with ..

The following two viewpoints are not consistent: “Come and work at our company. We are looking for someone with lots of experience. The more experience you have the more you’ll get paid!” “You made a mistake. You’re fired!” You can pick up knowledge at university and through reading books. But companies still want experience in addition to knowledge. For me, experience is very much having seen what works, and what doesn’t work, by havin..

Earlier today on an internal Heroku group alias there was a dataclip shared. The dataclip listed off some data grouped by a category, there was a reply a few minutes later with a modification to the query that used the crosstab function to pivot directly in SQL. There were immediately several reactions on the list that went something like this: While a mostly simple function in Postgres (there are a few rough edges), it really is all....

UPDATE : Google no longer supports spdy. Instead it focuses on http/2. This blog-post is no longer up-to-date. Today I tested nginx with Google’s spdy implementation.I already tested pagespeed separatly in a different post that showed the speed-boost gained from it. Now to add the security for you users. Screw you, NSA ! Installation Spdy is not built into nginx by default, so you have to download it separatly and build nginx wit....

Kolmogorov Complexity is kind of a cool idea, at least at first glance. You may know that the information content of an infinite stream of random symbols (measured in bits per symbol) is given by the entropy as described by Claude Shannon . The entropy is all well and good, but it would be nice to have a measure for the information content in a finite length string. Kolmogorov Complexity gives a nice description of the informa....

If you're going to change databases, do it in one go

At Uboot, there was the suggestion that we should change database technology. This was because we would save money with by moving away from Oracle to e.g. MySQL. It was further decided, as we had 200k+ lines of code, and 100+ tables, that if a migration was to occur, it shouldn’t happen “all at once”, but instead one would have some parts of the system migrated with other parts of the system not yet migrated.
