The Risk board game dice roll probability calculator and battle simulator

I know there are plenty of you out there who love to play the board game Risk. We're hooked on the Lord Of The Rings edition, and I still need to check out the very rare expansion pack one of my friends recently got. As you will see, I'm getting ready for it with all I've got, developing myself a weapon that will help me dominate the game. Something that will turn the odds in my favor without actually cheating. Say hi to my Risk battle simulator, which is able to calculate the chance of winning for specific Risk situations.

A case study in agile development: the algorithm for Ljubljana Realtime's event discovery

When we started working on Ljubljana Realtime, we decided to approach it in an agile way. Amongst others, we wanted to use a few interesting lean concepts such as rapid development, Minimum Viable Product and the Build - Measure - Learn iterations. Less than two months later, the results are in, and they are very pleasing. The MVP in the shape of an activity map was developed in a few weeks, only to show there is a lot of social noise which will somehow need to be taken under control. But that's currently low priority, since the first pivot is already taking place, slowly shifting the focus from the rich map application towards an event discovery algorithm and stream. That's where I see the most potential of Ljubljana Realtime, and in the last weeks, that's where the most work was done.

Putting 'people who look at you' to your Facebook profile would be the smartest thing to do

Are you one of those people who are wondering how Facebook decides which friends they put on your profile? I admit I am, both out of programmer's curiosity and of course, there have been rumors that those individuals are the ones who look at your profile. While LinkedIn offers this "who looks at your profile" insight to its (premium) users, Facebook is still very mysterious about it, denying this is how this particular algorithm works. But there is a simple reason I don't believe them: if I would be Facebook, I would design it exactly like this.

Did Google just admit Apple's Siri is the future of search?

I don't know if you saw The evolution of Google search video, which they've published a few days ago. You should, it's a cool movie, portraying the history of search and Google's vision of its future. But something went wrong. One of the punchlines of the video was a story from one of the engineers, who said that next-generation search engines will be able to answer complex questions such as the following:

Television and Social media? How did my recommendation engine miss this connection?

November has been a great month for this blog. For the first time in history, I managed to get more than 1.000 unique users on two different blog posts in a single month. Which is awesome, thanks! The first post was about the TV show Dexter and its Facebook game Slice of life. The other was about Slovenian TV show Soočenje and its buzz on Twitter. Just two posts, nothing special, right? Wrong. It's really obvious, but I missed it somehow. Both posts are talking about combining television and social media, silly me! I can't believe I failed to see it, but I did, and so did my blog. Not that it really matters anymore. You know those fantastic coincidences that happen sometimes and put everything into place? This story is full of them.

The great aquarium cleaning dilemma: should you be removing or replacing water?

Everybody that owns an aquarium probably came across this decision at one point. The water is filthy and needs to be replaced. All you have is a jar. And you ask yourself: should you be emptying the aquarium first, adding new water later on, or should you be replacing filthy water with clean water? The first choice seems more rational, but sometimes you can't fully empty the aquarium (e.g. you have fish), and you need to do more runs since you're not taking water both ways. The other option seems interesting since you're efficient both ways, but at the same time you're taking back fresh water mixed in the aquarium. So, what should you do?

Please help me upgrade my Twitter bot

Half a year ago I decided to make something out of my Delicious bookmarks. The magazine-style display inspired by Flipboard wasn't enough, I wanted to publish these links somewhere outside my chronolog, somewhere on Twitter. So I made a bot. It's doing quite well, posting like mad, but it's really not where I want it to be. Until now, it made about 3.000 tweets (around 500 per month), but has only 67 followers. I know my taste in content is a bit obscure, but still, only 67 followers?
