This is going to be a radically different trip report, we weren’t just talking at Java One this year we were actually presenting with our own booth and would probably do so again next year. Last year we tried to purchase a booth as well but were unable to get in contact with the right person at Oracle before the conference sold out (which was a shame, I understand some pavilion space went for free). This year we were ready though and were a..

I recently wrapped up a fun paper with my coauthors Ben Fish, Adam Lelkes, Lev Reyzin, and Gyorgy Turan in which we analyzed the computational complexity of a model of the popular MapReduce framework. Check out the preprint on the arXiv. Update: this paper is now published in the proceedings of DISC2015. As usual I’ll give a less formal discussion of the research here, and because the paper is a bit more technically involved than my previou..

Before I dived in earnest into writing the new version of my computer game that teaches Python, this time with game mechanics based on the classical puzzle game “Sokoban”, I wanted to make sure that Programmable Sokoban is a fun concept. So I wrote a prototype in a couple of hours. The programmers among you […]

A great companion to yesterday’s post, 10 Typeface Pairs for Cash-Poor Designers , for those looking to improve the design of their site through the adoption of strong design principles. Despite its original publication date of 2009, the best practices Michael Martin puts forth here have retained their value over the years in an excellent resource for aspiring designers. I have applied some of these lessons, too, in the creation of my elus..

This is just a short blip for people running Docker on CentOS who have encountered problems accessing containers from outside the localhost. The long and short of it is this command: shell sysctl net.ipv4.ip_forward=1 Why? Read this answer on StackExchange first. When Docker configures your iptables rules for network access, it likes to create a docker0 interface alongside any other network interfaces (like eth0) that Cen..

A hot subject these days is privacy. Since the Snowden's leaks we have been getting headlines about privacy every two or three days. This post is not about something new but it's to dwell into ways of thinking we haven't been accustomed to. I don't personally have any interest in conspiracy theories and secret societies but it's still interesting to relate it with terrorism, as we are in an era of psychotic people.

I plan on returning here and to other resources like it when it comes time to redesign this site once again; great advice, especially help..

Whole frameworks have been written with the purpose of handling the configuration of your application. I prefer a simpler way. If by configuration we mean “everything that is likely to vary between deploys”, it follows that we should try and keep configuration simple. In Java, the simplest option is the humble properties file. The downside of a properties file is that you have to restart your application when you want it to pick up changes.

Over the last few years we have seen the rise of a new type of databases, known as NoSQL databases, that are challenging the dominance of relational databases. Relational databases have dominated the software industry for a long time providing mechanisms to store data persistently, concurrency control, transactions, mostly standard interfaces and mechanisms to integrate application data, reporting. The dominance of relational databases, how..

Most web applications will add/remove columns over time. This is extremely common early on and even mature applications will continue modifying their schemas with new columns. An all too common pitfall when adding new columns is setting a not null constraint in Postgres.

Reading this article from Outside Online, it reminded me of a story a family friend once told me. She explained that her son and daughter-in-law, both schoolteachers in Alaska, had decided to raise their young son without the traditional lessons society dictates a small boy learn during his formative years. As far as his dad was concerned, if he never learned to play baseball, that was just fine: instead he would learn about the outdoors, a..

This was about two years after the initial revolution occurred that removed Hosni Mubarak from power, and nearly a year into the presidency of Mohamed Morsi from the Muslim Brotherhood. At the time Alaa was out on bail, facing charges for his involvement in demonstrations several months earlier (he was organizing against provisions in the new constitution that allowed civilians to be tried in ..

A little while back I spent some time looking at an interesting issue with a colleage. He was trying to load a virtual machine from an .OVA but kept recieving error messages as he loaded it that the file was invalid. Somehow though, other people used the same file. This one could be fun to diagnose. To start with, the premise of our argument has a problem: it wasn't the same file but rather a copy of the file.

The Mona Lisa Leonardo da Vinci’s Mona Lisa is one of the most famous paintings of all time. And there has always been a discussion around her enigmatic smile. He used a trademark Renaissance technique called sfumato, which involves many thin layers of glaze mixed with subtle pigments. The striking result is that when you look directly at Mona Lisa’s smile, it seems to disappear. But when you look at the background your peripherals see a sm..

Just as I no longer derive the same pleasure in reading ab..

Back to the brain we go. I already had snails eating food in jars before, but it was kind of a hack. Each snail would just eat a bite of whatever consumable item was in the jar. When I stupidly decided to try to make a simple snail brain, I knew I’d have to make things like eating fit into it. Today I made a very rough version of something like that.

Yesterday I gave a talk at Dev Workshop Conf introducing the basic concepts of vertex and fragment shaders. Unfortunately I don't have a video, just this one potato picture: It's probably for the best, because Chrome locked up on me halfway through. The slide deck is pretty cool though. It includes over 20 interactive WebGL samples, complete with source code. Check it out and let me know what you think!
