    He was home schooled and took an interest in Astronomy after getting a gift of an Astronomy book from his mother. He was accepted by the Astronomy society when he was 11.

    Really enjoyed his shows even if they were late at night. That was intended - you could watch his show, go outside and see the sky for yourself, if it wasn't cloudy.

    Being caught out at low tide in river deltas would have driven the need to survive in freshwater. Being caught out in small pools would probably have been the driving force to survive in air.

    But then you get people laying down all sorts of traps that kill everything and not just the pythons. Anything that is killed and isn't a python is just tossed away.

    Seems a humane way would be to place down thousands of trapboxes with live webcams, and have some image recognition software to recognise python patterns or just have a "something interesting" button.

    Methane is CH4, one carbon atom bonded to four hydrogen atoms. When you burn CH4, it forms CO2 + 2 x H2O. You get more water and more carbon dioxide, which both go into the oceans and atmosphere. Which in turn, makes the oceans more acidic, and if the climatologists are right, heats up the oceans even more.

    Do what Coca Cola does in some European countries (Norway for one) - have a vending machine that can be payed by SMS. You send a text tag, something like "ajx005" to the five digit number for that area, and the machine is credited with that amount. Perhaps they could make it simpler by having a QR code to read to eliminate the need for typing, and also to allow the selection of multiple items.

    Yes, still brings back memories.

    Still have my old Atari 800 and 800XL along with all the bits and pieces acquired every Christmas (sprocket printer, little graphics tablet that used the paddle ports for input, the little plotter printer. But then, by the time you had all those, you needed two extension bars for all the different transformers (keyboard, TV, disk drives, printers, RS232).

    Fortunately, there are emulators for the Atari and all the other home computers like the BBC. I've used to them to type in the listings from archived articles I had always wanted to try out. All those program still run, even the "100+ free programs" that came from the shop I bought them from.

    In one of my previous workplaces, these mail-storms would blow up just about every Friday afternoon. One admin would be told to create a new mailing list from a merge of several others, which of course included several other mailing lists as members. Then those on the distant branches of those lists would want to unsubscribe.

    I used to do some transcription work to make a bit of spare cash. At the beginning of the tape, I really wouldn't understand the accent, not recognising some words, but after going through the tape once and replaying it, I would immediately recognise the words. It's almost as if there were a set of mask images for every word, and these didn't quite fit at first, but after 20-30 minutes they were scaled, rotated, and transformed in some way until they made a better match. Each word would also have a limited set of other words that would come after it, so that also narrowed down the set of possibilities.

  15. Re:Sources of improvements? on A.I. Advances Through Deep Learning · · Score: 1

    Everything ran into a big wall 20 years ago. There were 680x0, DEC Alpha and SPARC systems, but they were either $10,000 workstations (with no disk drive, server or monitor for the price) or there were embedded systems requiring a rack chassis development kit (manuals cost extra).

    Image processing on a PC CPU (= 80386) had to be implemented as a script of image processing command line functions as it wasn't even possible to reliably allocate more than one 64K block. You would load the image in line by line, apply a DFFT, write out the image line by line, flip the image across the major diagonal, then repeat the process. Every image processing function would have to be implemented in this way. General purpose servers were much faster.

    Alternative was to use primeval graphics processing boards which had some exotic combination of DSP's and CPU's (Intel i860 CPU, TI32020 DSP, TMS340x0 chip). Some graphics boards at the time actually had a network stack/socket built in so that images could be downloaded straight into video memory and bypass the CPU.

    Now any department can buy a cloud server with Terabytes of storage, a couple of PC's with GTX680's, HD webcams, and download free image and video processing software.

    It still flips me out that smartphones do texture mapping, multi-texturing at that, when just 15 years ago, that would have required a $10,000 graphics board on a desktop.

    I once paid a visit to my local antique shop. What freaked me out was that they were selling microwaves, digital camcorders (the type with cassettes) along with

    The old BYTE magazines from the 1970's and 1980's were wonderful reading. The Circuit Cellar guide to building your own home security system with a 20Amp klaxxon air raid siren in the basement. Reviews of the workstations (Next Cube), motherboards and graphics cards of the time. What goes into a single ASIC now, would go into a dozen little chips and a full-size daughter board. State of the art visual effect was a silhouette halo like in Xanadu.

    Had the chance to program 8-bit home computers like the Apple ][, Atari, BBC, and Atari ST. There were so many magazines out there, all giving program listings and information on building things like light pens, mini device drivers and games written in assembler. These days, you would get sued just for using a function call the wrong way.
