The First Digital Computer (Not ENIAC!)

26-Aug-2004 By Jim

Despite what the history books say, the ENIAC was not the first digital computer in the world; the COLOSSUS was, but since it was developed secretly during World War II, the British (those that knew about it) have had to suck it up whenever we Yanks touted our (false) superiority. Until the 1970s, when details of the machine’s existence were made public. Of course, none of the textbooks used to teach American students has been changed to reflect reality, at least when I was going to school.

Unfortunately, all the hard-copy schematics of the machine were destroyed in 1960, except for a few drawings, kept illegally by engineers, which were divulged during the rebuild project in the 1990s. The rebuild was started based on eight! photographs of the machine and a handful of grey-matter recollections. In 1995, the NSA in the US was forced by a Freedom of Information Act request to declassify 5,000 documents pertaining to the Colossus. Several of these documents were helpful in rebuilding the machine; one in particular, written by Albert Small, thoroughly described how Colossus worked and enabled a significant amount of progress in replicating many of the mechanisms of the machine. Colossus is estimated to be about 90% rebuilt now and there’s work begun to rebuild the Colossus Mk II and the Tunny machine.

If you’ve read Neal Stephenson’s Cryptonomicon and enjoyed it, you have to read about this. I’m personally fascinated with the early days of cryptanalysis and how it helped to birth the digital computer age. It’s absolutely amazing what was engineered and built before the advent of the transistor (which is to say, before I was born). I’m sure some will be loathe to read it, but this is one example of something non-violent that Hitler caused to happen, by his clever use of large-scale machine-based encryption, which undoubtedly precipitated the computerized world we now live in — or maybe that’s just my naïveté showing.

Digital panoramas, but…

26-Aug-2004 By Jim

Link: digitalmedia.oreilly.com…

A good article on the subject, but…

I’ve tried doing panoramic shots; I’ve tried really hard. With a camera with an off-center tripod mount; with one that’s in-line with the lens; and without a tripod at all.

The problem is parallax, and I have yet to see any decent how-to for panoramic shots that even mentions the word, nevermind instructing one how to avoid or minimize it. Panoramas are great for landscapes and such but what if your subject has long horizontal lines (for example, stairs) in the foreground and you can’t physically move to compensate? Or, what if you have, instead of horizontal lines, regularly repeating vertical lines (for example, lightposts) — heaven forbid you have both at once. The lightposts themselves aren’t the problem, but they tend to move against the background as the position of the camera changes in each shot. I spent over an hour in the Memorial Church courtyard at Stanford on each of two mornings trying different techniques to capture the place but was foiled by one or both of these problems (depending on the technique).

Maybe it’s just the “perfect” sample photos you see with articles about these things and that they purport to make the process simple and easy. Fine, and they’re accurate to an extent. But next time, let’s have a little paragraph on how to avoid choosing a less-than-good subject, okay? Extra credit if you include a sentence using the word parallax to describe part of what you’re avoiding.

From me to Mary (and Tammy, and …)

Scare quotes, oh my!
Link: www.suck.com…

Scare quotes are the quotation marks found around phrases like “gangsta rap,” “shame spiral,” or “security zone”: coinages that may be lingo, that may be jargon, that may even be slang but are more likely excuses where a little distance is in order. The subject of the story may say it’s “the truth,” but we say it’s spinach and — ya know what? — to hell with it. Scare quotes throw a net around the ideas and assertions media culture hasn’t absorbed yet, stuff journalism’s jobholders may even be a little afraid of.

National Punctuation Day is Aug 22

You know who you are. You’re reading the SubQ and you have to take deep breaths because some submitter doesn’t know the difference between “its” and “it’s.” Or you shudder as someone thinks the plural of banana is “banana’s.” Or you find yourself unintentionally bemused by someone’s misuse of “scare quotes.”

The good news is that you are not alone, if sales of the surprise best-seller Eats, Shoots and Leaves: A Zero-Tolerance Approach To Punctuation by Lynne Truss is any indication. The unlikely smash has topped best-seller lists in the U.S. and Britain, and is among Amazon’s top worldwide sellers.

How did this happen? How did an fussy editor airing her pet peeves about punctuation become an international sensation? Truss herself isn’t sure, and views the whole thing as a “complete fluke.” She hardly expected its success, but takes comfort in knowing there are other sticklers out there. “I wrote Eats, Shoots & Leaves because I’d become very animated about illiteracy,” Truss explained. “I had no idea so many people shared my concern. It’s very heartening. Because I’m not myself a parent, I underestimated the extent to which ordinary, decent folk are worried about the kind of education their children are receiving.”

The book is probably not for everyone, as people who aren’t writers, editors or at least mildly word-obsessed may find it a bore. Others may be taken aback by her obsession, which included a regrettable episode of shredding a childhood pen pal for a perceived lack of literacy. She admits that sticklers like her can be “an annoying bunch of people.” But the book has received a boost from the expected friendly journalists, as well as those gearing up to salute National Punctuation Day on Aug. 22. If nothing else, it yields such bits of trivia as learning that 15th-century printer Aldus Manutius the Elder invented both the italic typeface and the semicolon. And she tries to make the process fun, offering up a punctuation game on her Web site, as well as the guilty pleasure of a punctuation hall of shame (where you can even submit your own photos chronicling abuse of the English language).

For all her humor, Truss sees slumping writing standards as a serious problem. She winces at discovering during televised quizzes “that most British people truly do not know their apostrophe from their elbow” and since learning that the United States “is not immune to similar levels of public illiteracy.” She notes the unfortunate timing of it all, as ignorance of the written word comes while written communication has become “the ascendant medium” because of the Internet, which “happens to be the most immediate, universal and democratic written medium that has ever existed.”

What is ”Slashdot”?

Blatantly ripped without permission from anyone but it is entirely intact…

Basically, your correct.

Last time I checked we’re on the “IN-TER-NET”. You know that place that is practially a blackhole of all things immature.

If you were to map the internet like a galaxy, Slashdot would be tucked over in the corner next to the obscene jokes and well stuff involving well hung midgets and horny lonely housewives.

Microsoft could release a patch that just by installing would cure world hunger and shrink maligant tumors and the headline on Slashdot would be “Microsoft distrupts food distribution and healthcare systems worldwide!”

So, in short, if your looking for unbiased punctunal and definitative coverage of the every evolving internet, this is not the place.

If however, your looking for the diatribes of cynical, world weary geeks, who know the whole world is basically built on match sticks and is gleefully waiting for the day the whole place comes tumbling down, you’ve found it.
