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?

Determining if an element is in the last row of a table

Once upon a time I stumbled upon a problem, where I needed to calculate if an element is in the last row of a table. Here's the scenario: you have a number of items, which are put in a table from left to right. When the row is full, the items continue in the next row. Imagine an airplane or a theater where people start sitting front-left and continue to the right until they run out of space, then going to the next row and so on. Now we want to know which people are sitting in the last of the populated rows.

Is Delicious aiming to become the next Twitter?

The bookmarking service Delicious has had an interesting life. It was one of the first social services available, later bought by Yahoo and almost canceled, then being sold to Avos about a month ago. Avos was founded by the same people who've created YouTube (Chad Hurley and Steve Chen), and these guys obviously know what they're doing. A few days after acquiring Delicious, Avos also bought a social media analytics startup Tap11, and here's what they had to say about it:

A few thoughts on content categorization. No surprises there, less is more.

Since I've started collecting bookmarks using Delicious, I've put a lot of effort into their categorization, organizing them in such a way their browsing would be as simple as possible. The service supports two level categorization (tag – bundle) which helps to control massive amounts of links people have gathered. But it's the experimentation with different structures that gives real insight into content categorization, and because this topic was already mentioned and discussed a few times on this blog, it deserves a special mention. Let's begin.
