Warbothong (905464) writes "The debate between pragmatism and purity in programming languages has been going on for decades. Pure languages forbid side-effects in their computations (eg. changing a variable), since they make formal analysis hard; whilst pragmatists embrace them to allow quick production of 'good enough' code. A new experimental language called Eff, created by Andrej Bauer and Matija Pretnar, is blurring this distinction. Eff is based on a Mathematical model of side-effects, allowing it to harness mutable state, exceptions, IO, random choice and more in a pure way from within a Python-like syntax. The product of on-going research, Eff is still in its infancy and, as its authors state, "...is an academic experiment. It is not meant to take over the world. Yet."" Link to Original Source top
Warbothong (905464) writes "Researchers at Southampton University in the UK have developed a tiny (less than 1 cubic centimetre) generator which uses local vibrations to output microwatts of power, making it an alternative to batteries, which need replacing regularly. The devices are currently being used in industry where "there is the potential for embedding sensors in previously inaccessible locations", but its creators imagine it could be used in devices such as pacemakers, where the beating of the heart would produce ample movement for the magnetic mechanism inside to work."

Warbothong (905464) writes "I am going off to University this month, so I have been chasing up payments and deposits, etc. online. The other day I received an email confirming that I am all payed up, which is great. The not-so-great part was the email's header, since after "To:" it had a list of 1343 email addresses, including mine. It is pretty clear that all of these addresses are for students paying their deposits online, and it is also clear that this list has been sent to 1343 people.
In our world of datamining and spamming I am pretty concerned that sooner or later this list will get into the hands of someone who might want to make a bit of money from a list of 1343 valid email addresses, all in active use, all owned by soon-to-be students at a particular University in the UK who all have the capability for making online payments, so I am wondering what Slashdot readers make of this? Should I be worried? I have already sent an email of concern to the Reply-To: address, and got a swift response that this matter will be dealt with "immediately", but I am not sure there is much that can be done at this point.
