Now it's Maryland

Another brain fart from Harry. I understand technical things are beyond your comprehension but you don't need to be so proud of it. I don't have any problems moving .jpg's to and fro. I know better than to try to do so with my usenet provider in a "non-binary" newsgroup or whatever was being tried that didn't work. Oh, and I had more than 50 articles published in PC Week, PC Magazine, BYTE and a few lesser pubs. I had a biweekly column in PC Week. Your computer oriented technical articles consisted of...??? Uh huh. So If I go look at the archives of PC week or PC Mag I will see a lot of "technical" articles from Harry Krause? We are not talking about case styling and the feel of the keyboard are we? They were probably letters to the editor. In fairness, I remember reading something Harry wrote in some PC magazine. He used to volunteer to do beta testing and provided feedback. Yabut, he said he was published in BYTE. That was a highly technical magazine written by very competent engineers. They published stuff like schematics of computer circuits complete with timing diagrams and sample code to perform complex functions. If true, they must have needed some fluff filler piece because he doesn't have the engineering chops to write anything that they would normally publish. When it comes to computers, neither do I. :-) I got a kick out of a visit from my younger son the other day. He started a new job as a facilities manager for a company that uses automatic, high volume packaging equipment. He took electronic engineering courses when he attended MA Maritime but they only covered digital logic circuits. They don't even teach theory anymore and vacuum tubes, transistors, etc. are artifacts of ancient times. One of the systems he's responsible for broke down due to a bad rotary actuator. He was having a problem ordering a replacement because there were two versions of it. One was a PNP type, the other a NPN. My son had no clue what PNP or NPN meant. All he knew for sure was that they had a magnet in them along with a small chip. I explained he had a "Hall Effect" circuit and spent some time explaining what PNP and NPN meant, drawing diagrams of transistors and explaining what the base, emitter and collector were. Then I drew a diagram of a vacuum tube with the cathode, screen grid and plate, while explaining how it worked and the similarities in function to that of a transistor that came later. Now-a-days everything is on a chip the size of your little fingernail and it probably contains a dozen or more and, or, nand or nor gates or transistors used as gates. It's worse than that. Those tiny little chips contain a whole lot more than just gates. The days of building logic circuits using gates in dedicated chips is pretty much gone. Now the vast majority is done with programmable logic devices (PLDs) and their variants where you just design the logic in an app and assign the inputs and outputs to the pins, then program the chip to perform that operation. A complex programmable logic device (CPLD) can contain 10's of thousand of logic gates, and is programmed after being soldered on to the board with serial data (usually JTAG) while in-circuit. |
