Donald E. Knuth talks about New The Art of Computer Programming Book Chapter

Donald E. Knuth Talks about SAT SolversIn his latest talk about SAT solvers at the Johannes Kepler University Linz (JKU), Computer Science pioneer Donald E. Knuth gave a deep and quite emotional insight about his life-long, epic work on the book ‘The Art of Computer Programming’. The Art of Computer Programming, aka TAOCP  represents the one and only global reference on algorithms, their analysis and computer programming in general and is the standard work for all computer scientists worldwide.

Donald E. Knuth talked about his recent chapter within TAOCP on SAT solvers and how fascinating these satisfiability problems as well as the derived problem and number patterns are. Knuth invited the audiance to ask all kind of questions, which span detailed explanaitations on his love for TEX as well as for his CWEB language, to quite personal topics, such as Prof. Knuth’s love for organ music and that he might also write down his own organ composition. During his trip through Austria, Prof. Knuth also had the chance to play on famous local organs, such as the organ within the monastry of St. Florian where Anton Bruckner was playing in 1850.

To summarize, Prof. Knuth gave a fascinating and very inspiring talk about his actual work and it seems as if there will be a lot of topics and chapters within the coming years!

He also shared an interesting advice with his audience: “If you are not fascinated and interested in what you are doing, then you are the only person to blame for!”

Some days ago a friend told me that his team just published a brand new iPhone and Android App called Spotnick that allows mobile Facebook users to immediately locate and track their friends. After connecting to Spotnick by using your Facebook account, you are shown a map on which you can locate your linked Facebook friends. As far as your friends are not updating their location in realtime, Spotnick uses the actual home address, or the last known address your freinds entered within Facebook. The Spotnick app also allows to track and update your own address in realtime, so that you can select people who are allowed to see your realtime location. Spotnick app was published for Android as well as for iPhone.

apps4austria: Challenge to Create Community Apps by using Open Government Data

Logo apps4austriaapps4austria is a federal Austrian Challenge to create mobile Apps by using Open Government Data archives. These archives contain all kind of information that could be used by a wider public community, such as location of waste collection centers, tourism information, public statistics or public building information.

The challenge emphasises the design of apps that are using these kind of publicly available information and visualizations. Its even possible to submit concepts and ideas without concrete implementation. The submission of apps4austria is due to 1.march 2013!

Arduino Controlled Magic Chess Board

This Arduino controlled Chess board set tangibly connects two players with each other from anywhere in the world. To combine physical interfaces to intuitively control virtual environments gives users the possibility to control all kinds of digital technology without much background knowledge. The combination of tangible artefacts with digital content is called ‘Tangible User Interfaces’. This amazing chess board game is a perfect example for such a tangible interface approach.

Plant Link – Smart Embedded Gardening for Everyone

Plant Link, recently started to fetch funding on Kickstarter tries to make your gardening a little bit smarter than usual. The inventors of Plant Link promise that by using their smart plant monitoring device even the biggest plant killers get a green thumb.
Plant Link is a hardware device that monitors the water needs of your lawn, garden, or house plants. It alerts you on your iPhone when your plants need to be watered and can even water them for you, at least for a while. Plant Link is designed for indoor as well as for outdoor use, just put it  beside a plant you would like to monitor. Plant Link is then acting as the ‘Big Brother’ for your plants as it is configured and paired exactly for one type of your plants, as each family of plants has different needs. It is even possible to log into the Blog of your plant to see if they are doing well or not. Plant Link perfectly follows the actual trend of green gardening technologies.

With Plant Link the Internet of Things is definitely growing into an Internet of Plants as well 😉

Facebook’s Social Graph Search – Semantic Search for People, Places and Things

Facebook recently  announced Social Graph Search, a new kind of semantic search engine that allows you to query Facebooks social graph data structure by using natural language queries. Facebook specifies some interesting but harmless samples for social graph queries, such as search for ‘People who like Cycling’, ‘Photos i like’, ‘Photos before 1970’, ‘Restaurants in London my Friends have been’ and so on. These queries seem to offer real potential for natural language processing in the area of social graphs. to use natural language processing for query large data graphs is not new, as it was already introduced by WolframAlpha, in order to query for all kind of general knowledge, from local weather to mathematical questions etc.

Facebook goes a little bit further by introducing a natural query language to search for quite personal information within a global available social graph. It of course depends on the type of queries that transforms Facebook’s social graph search into an informative personal tool for everyday life, or into the nightmare for every privacy activist. Some already published queries, such as ‘People working for Facebook’ or similar searches are quite scary and will for sure lead to misuse and dubious apps.

From business perspective the use of social graph queries allows advertisers to specifically select their target groups, even better than existing context- and location sensitive solutions already allow it today. Facebook’s social graph search will lead to a new level and quality of advertising, no matter if this means more or less advert annoyance for the future.
