The well documented history of programming languages contains some that never existed which were then invented and aptly named as a result. Ada is one of those languages; although Ada Lovelace never saw a machine that Charles Babbage never built; she did write software for it that would in theory calculate Bernouli numbers, and has since been proven to work.(Baum)i Although Ada is a retronym (a term applied after the invention’s creation); there were many languages available and used before ADA, these include ALGOL, APT, FORTRAN and many others. (Piggot)ii The logical history of software is available from the HOPL, a site devoted to the archival of all programming languages (Piggot)iii; although we could argue that the Jaquard Loom in the late eighteenth century (1890) was the first use of punch cards, and the first programming language to make use of recursion to produce fine rugs; the cards were actually pre-dated by switches when it comes to computers and programming.(Penn)iv The r...

The primary reason that physical disks are around two orders of magnitude slower than the registers and cache of a central processing unit is the simple fact that one relies on physical motion, whilst the other utilizes waves of electrons operating at speeds close to the speed of light. The only limiting factor for the speed of a wave of electrons traveling through a semi-conductor is the material and its fabrication size this is often referred to as the fabrication “Process” used. In turn the process produces the physical limitations of the solid state circuitry. The theoretical mathematical limitation is described by Taylor and Wheeler (1992)i to be 2L/c where L is the average distance to the memory and c is the maximum celerity. The primary limiting factor within a central processing unit is propagation delay as well as the distance to the physical memory. Since the next limitation is the core oscillator that acts as the CPU’s clock we see that there are no moving components...

Yay, another week and another 3 assignments; here's my latest: Since the invention of digital computing machines such as the Manchester Small-Scale Experimental Machine,(University of Manchester, 2005)[i] , non-volatile storage has been a requirement as a result of the stored-program concept.(Brookshear et al, 2009, p.102)[ii] As outlined in sections 2.1 to 2.4 of the above text; Machine language in conjunction with computer systems architecture is what is used to accomplish work within any digital processing system; although the machine language, systems interface buses, volatile memory, ie; Random Access Memory (Ram), and non-volatile storage mechanisms may differ from system to system, the one requirement all computing machines maintain is non-volatile storage accessed via a controller. (Brookshear et al, 2009, p.123 – p.125)[iii] The first paradigm of non-volatile storage utilized was paper tape followed by punch cards followed by cathode ray tubes and eventually ...

A long long time ago in a galaxy far far away were a bunch of dudes that thought your rights were worth something. They have long since been dead, here in Canada we still have some privacy advocates but their ideas are eroding as well. We passed an act similar to the Patriot act in the U.S. our "War on terror" is simply severely underfunded. The United Kingdom did the same thing, what's really odd is that theirs was sparked by train bombings. A great man once said: If we sacrifice liberty for security even temporarily, we deserve neither! That's as true today as it was three hundred years ago. In the latest onslaught against the rights of an individual; Phoem in the United Kingdom is going to team up with BT, now I hate British Telecom for a number of reasons, one of them is that it's a federally subsidized monopoly on telecommunications. Any Monopoly on telecom is bad; I say let the companies play and kill one another and then the monopoly that comes out of that ...

So yet another morning of generating reports has gone by, I came across IEC based Fusion in my last post, Electron Power Systems. Then I thought, why not look into that idea? it's a viable form of low cost fusion, so what the hell right? In my mind physicists are people that have energy complexes, they love putting huge amounts of energy into tiny spaces; say like a macho man that drives a really nice car, although science won't let you afford a nice car, but it just might save the planet. (tm) Enter the Google talk with Doctor Robert W. Bussard, available here: http://video.google.com/videoplay?docid=1996321846673788606 If you have the hour and thirty six minutes as well as a good command of the English, engineering and physics languages you may just understand what he's saying. I'm not even going to attempt to digest it at the moment because I am still digesting what he means by B-fields (H/B magentic feilds?) and gyro-radii (radius of rotation of an electron?), of co...

In the millions of ideas that plague my clouded and hectic mind I've wondered about a lot of things. One of them is our ongoing energy crisis. A good friend once told me that If i could find a way to access the frozen methane under the continental shelf I'd be rich a few billion times over since this is the worlds largest deposit of natural gas, it's just below a thousand feet of water a few hundred meters of rock and frozen. Then there's the psudeo science crowd claiming that Maxwell, Planck and Einstien were wrong and that Tesla was right and that we can pull energy from static charges or the zero point. ZPE does exist and it is real, the only effect that has been measured by physicists is the Casimir one. http://en.wikipedia.org/wiki/Casimir_effect This force is more akin to gravity than anything else, the brilliant folks at the university of St. Andrews in the united kingdom figured out how to levitate things with it, I posted about it earlier last year. http://www....
