Some time back, I acquired a Micromoog analog, monophonic synth. These little beasts are a single oscillator synth, but include a sub-oscillator, 24dB/Oct filter, good modulation, ribbon pitch bend and CV interfacing. The clincher was one appeared cheap on Ebay advertised as requiring "Tender Loving Care": the wooden base needed replacing, but that it did work.
I already have a Multimoog, which is a two oscillator, pressure sensitive keyboard version of the Micromoog, and the thought of operating the two in unison was too great an opportunity. The Multimoog needs work on the power supply and obtaining a Micromoog helps diagnose the Multimoog's power supply behaviour. Expect a blog about the Multimoog in the future.
A friend who has returned to studies, and therefore low on cash, had bought a second hand PowerMac G4 Mirror Drive Door model. After a good many years of service with the previous owner, and a year with him, the G4's power supply died, as that model is inclined to do.
Repairing the powersupply is dangerous and difficult, and obtaining a second hand replacement is expensive, and that model was notorious for how loud the power supply was.
It’s time to fix our immigration system.
Our current immigration system is failing the world’s most vulnerable people.
With the Australian federal election impending, once again it's time to ignore the personality contest and concentrate on reviewing the policies of the various contenders in your electorate. Reading some of the news comments by non-Australians reveals little is known about preferential voting and it's value to creating Australia's stable political system.
While this article by Antony Green is almost 6 years old, it's a nice summary of the Australian electoral system and it's preferential voting system. Most interesting is how different parties across the political spectrum have benefited over the years (since 1918) from preferential voting.
While I applaud the advocacy for light rail by The Greens, the greatest impediment to adoption will be the start up cost. This consists of the three major infrastructure expenses: construction of electrical power lines (overhead or third rail arrangements), installation of rails, purchase of rolling stock.
Taking an almost random sample of the response to the Wikileaks revelations of the criminal slaughter of Afghan civilians by the overwhelmingly U.S military, Foxnews diatribe by Gutfeld is perhaps the local maxima.
It's curious that while Gutfeld is accusing Julian Assange of selectivity in what he is choosing to leak: "The fact is, their goal is to "expose" only the people they hate — meaning the U.S military — and get famous for it", Gutfeld's diatribe is significantly greater in it's selectivity and hypocrisy.
In the New York Times piece reporting the planned introduction of rental electric cars in Paris, the piece opens with frightening tales of the number of the Velib rental bikes that have been damaged in the history of the operation of the system. This clearly is intended to communicate how much the system has failed.

Computational models of beat tracking of musical audio have been well explored, however, such systems often make "octave errors", identifying the beat period at double or half the beat rate than that actually recorded in the music. A method is described to detect if octave errors have occurred in beat tracking. Following an initial beat tracking estimation, a feature vector of metrical profile separated by spectral subbands is computed. A measure of subbeat quaver (1/8th note) alternation is used to compare half time and double time measures against the initial beat track estimation and indicate a likely octave error. This error estimate can then be used to re-estimate the beat rate. The performance of the approach is evaluated against the RWC database, showing successful identification of octave errors for an existing beat tracker. Using the octave error detector together with the existing beat tracking model improved beat tracking by reducing octave errors to 43% of the previous error rate.
