13 Laser is produced by a living cell. The technique starts by engineering a cell that can produce a light-emitting protein that was first obtained from glowing jellyfish. »

29 Cleaning Up Radioactive Mess with Blue Goo. A clever technology is helping crews in Japan contain and clean up the contamination caused by the ongoing nuclear disaster there: a blue liquid that hardens into a gel that peels off of surfaces, taking microscopic particles like radiation and other contaminants with it. »

27 The Art of the Animated GIF. Animated GIFs are like the jazz of the internet: they could only exist, and be created and appreciated, online. Photographer Jamie Beck and motion graphics artist Kevin Burg may have finally found a way to elevate the animated GIF to a level approaching fine art, with their "cinemagraphs" - elegant, subtly animated creations that are "something more than a photo but less than a video." »

27 Proof That Einstein Got It Right. Einstein's general theory of relativity predicts that massive, spinning objects like Earth should warp space and time around them, as well as drag space and time along as they rotate - as a dipper twirling in a honeypot would spin honey. Francis Everitt talks about how NASA's Gravity Probe-B experiment has just confirmed both predictions. »

27 USB-stick PC could sell for £15. A miniaturised computer could sell for as little as £15 when it is launched next year by veteran computer games developer David Braben. The device, produced by a new group called Raspberry Pi, is approximately the size of a USB memory stick. »

30 Ultrafast fibre optics set new speed record. Two separate research groups have just set a world record by sending more than 100 terabits of information per second through a single optical fibre. That's enough to deliver three solid months of HD video- or the contents of 250 double-sided Blu-ray discs. »

23 Dutch To Build Solar Panels Into Their Roads. The Dutch are well known for their ubiquitous bike lanes, to the point where Amsterdam is neck and neck with Copenhagen for the title of most bike-loving capital in Europe. Now, Denmark will have to come up with something big to match the latest plan from the Netherlands - the installation of solar panels in roads, starting with bike lanes. »

23 Rumor that "God Particle" Has Been Detected. A rumor is floating around the physics community that the world's largest atom smasher may have detected a long-sought subatomic particle called the Higgs boson, also known as the "God particle." »

Apr
23 Lasers May Replace Spark Plugs. The spark plug's days are numbered though thanks to a new breakthrough from some scientists that have found a way to replace the spark with a laser inside the internal combustion engine. According to researchers, the move to lasers from spark plugs will allow cleaner and more efficient vehicles and with the looming increases in mandated fuel economy, the auto industry will need all the help it can get. »

Source code

The list below contains standalone classes that contain useful or novel features that have proven useful in the past. All classes are packaged as part of the KoBeans library.

CSVTokenizer

CSVTokenizer class, used to parse CSV-format lines. CSV files can be read line by line, and each line can then be processed using this utility class. What makes this class useful is that it can interpret the format of Strings in CSV files, which are enclosed by quotes and that can contain quotes "escaped" as double quotes. Otherwise, it is not much different from a regular StringTokenizer.

Source Code

Padder Class

Padder class, that can be used to pad numbers and Strings with a specified character. It is very simple and easy to use, and principally deals with the fact that the construction of padded values is a cumbersome thing to do without a utility class. It declares a padding workspace to eliminate the use of String Buffers and memory allocation, and is therefore best declared in a fixed place to be reused.

Source Code

PatternMatcher

Pattern matcher, used for simple pattern matching. It is simpler and considerably faster than regular expressions, but has less functionality. A pattern can contain multiple pattern expressions; a pattern expression can contain literal characters, single character wildcards and zero-to-many character wildcards.

Source Code

PerformanceMeter

PerformanceMeter class, a light-weight class used to calculate the processing time as well as processing rate of a block of code. It is best used in unit tests to produce performance benchmarks and/or to verify performance.
