http://i-programmer.info/news/181-algorithms/7662-speed-data-is-enough-to-track-you.htmlIf I tell you how fast I have been driving and for how long, you might think that the best you can do is to compute the radius of the circle I must be in given my starting point. In fact, the data provides much more information than you might expect and it is usually enough to give your exact route. So tell me your speed and I'll tell you where you have been.

http://i-programmer.info/news/181-algorithms/7639-algorithmia-an-app-store-for-algorithms.html
http://i-programmer.info/news/181-algorithms/7639-algorithmia-an-app-store-for-algorithms.htmlAlgorithmia is a new marketplace for algorithms where people who need to use an algorithm can find one without having to implement it for themselves and algorithm creators can get paid for their efforts.

http://i-programmer.info/news/181-algorithms/7015-riecoin-crypto-currency-mines-primes-for-riemann.htmlWhat a waste of effort bitcoin mining is -all that computer time just to validate transactions! Riecoin is a new crypto currency that uses a search for prime constellations as its proof of work.

http://i-programmer.info/news/181-algorithms/6917-an-envy-free-algorithm.html
http://i-programmer.info/news/181-algorithms/6917-an-envy-free-algorithm.htmlIf you want to find a way of dividing up some indivisible items between entities then here is a way to do it that eliminates envy as the outcome. The suggestion is that this could be a good way to divide up possessions during a divorce - algorithms get into everything.

http://i-programmer.info/news/181-algorithms/6571-flaw-in-bitcoin-algorithm.html
http://i-programmer.info/news/181-algorithms/6571-flaw-in-bitcoin-algorithm.htmlMost security analysts don't regard the Bitcoin algorithm as particularly sophisticated, but until a new paper was published there was no explicit flaw. However, the problem that has been uncovered is more to do with game theory than cryptography.

http://i-programmer.info/news/181-algorithms/6198-reaching-the-unreachable-pi-squared-and-catalans-constant.html
http://i-programmer.info/news/181-algorithms/6198-reaching-the-unreachable-pi-squared-and-catalans-constant.htmlYou may have heard the reports of computing Pi to millions of digits, but you might not know that there are other related constants that are much more difficult to compute. Now we are getting closer to being able to compute these values as well - and it isn't a matter of more computing power.

http://i-programmer.info/news/181-algorithms/5681-solve-the-riemann-hypothesis-with-a-quantum-computer.htmlA new quantum algorithm allows the computation of a range of prime number functions to be computed well beyond the limits of a conventional computer. It is even possible that it could solve the million-dollar Riemann hypothesis.

http://i-programmer.info/news/181-algorithms/5573-linear-solver-in-linear-time.html
http://i-programmer.info/news/181-algorithms/5573-linear-solver-in-linear-time.htmlSolving a general linear equation is more than quadratic in the size of the matrix, but if it has a particular form you can now do the job in nearly linear time. The breakthrough is not only faster, it is simpler and has lots of uses.

http://i-programmer.info/news/181-algorithms/5563-google-zopfli-nice-compression-shame-about-the-speed.htmlGoogle is offering us a new lossless compression tool called Zopfli. it can produce zip files that are up to 5% smaller with no negative effects on the end user. There is a catch - Zopfli is much slower than your average zip.
