Today's Jargon File Entry
ACK: /ak/, interj. 1. [common; from the ASCII mnemonic for 0000110] Acknowledge. Used to register one’s presence (compare mainstream Yo!). An appropriate response to ping or ENQ.
2. [from the comic strip Bloom County] An exclamation of surprised disgust, esp. in “Ack pffft!” Semi-humorous. Generally this sense is not spelled in caps (ACK) and is distinguished by a following exclamation point.
3. Used to politely interrupt someone to tell them you understand their point (see NAK). Thus, for example, you might cut off an overly long explanation with “Ack. Ack. Ack. I get it now”.
Today's Jargon File Entry
accumulator: n. obs. 1. Archaic term for a register. On-line use of it as a synonym for register is a fairly reliable indication that the user has been around for quite a while and/or that the architecture under discussion is quite old. The term in full is almost never used of microprocessor registers, for example, though symbolic names for arithmetic registers beginning in ‘A’ derive from historical use of the term accumulator (and not, actually, from ‘arithmetic’). Confusingly, though, an ‘A’ register name prefix may also stand for address, as for example on the Motorola 680x0 family. 2. A register being used for arithmetic or logic (as opposed to addressing or a loop index), especially one being used to accumulate a sum or count of many items. This use is in context of a particular routine or stretch of code. “The FOOBAZ routine uses A3 as an accumulator.” 3. One’s in-basket (esp. among old-timers who might use sense 1). “You want this reviewed? Sure, just put it in the accumulator.” (See stack.)
A little Quickie
I played a civ4 scenario for the first time last night. I played the American Revolution as the British. The map was really neat to play on, as they duplicated the eastern US pretty well. Each side starts out with about half of the cities on the map. Various actions cause loyalists to join the British or Colonials to take up arms. Also, accurately enough, the British are reinforced by German Mercenaries. From time to time British reinforcements arrive in Canada.
Subversive Kid's Tv Shows
I read a book a few years ago called “Don’t Tell the Grownups” about how some authors hid their dangerous messages in the form of children’s book. As I was listening to some music from the cartoon Animaniacs, I also heard some hidden messages that the kids might not quite understand. For example, in a song where the Warner Brothers sing the names of the US Presidents, they end the song with, “…the one in charge is plain to see, it’s Clinton - first name Hilary.” So even in this kid’s show we see the joke that Hilary is in charge of the White House instead of Bill Clinton. This is pretty mild, but even more contentious is where Yakko sings all of the countries in the world. He mentions Taiwan as one of the countries. As we all know, we’re supposed to pretend that Taiwan is part of China when, for all intents and purposes, it is its own country in all but name. But here we are training kids that it is its own country - very interesting!
How bad are video games really?
Wired Magazine’s April 2006 issue explored this premise in a very unique way. Instead of saying that we still don’t have conclusive evidence that video games do any damage (and in fact there is some that they are helpful in some instances) they mentioned that the battle between older adults and younger adults/kids is age-old. Below are the quotes they used in their article.
Novels
“The free access which many young people have to romances, novels, and plays has poisoned the mind and corrupted the morals of many a promising youth; and prevented others from improving their minds in useful knowledge. Parents take care to feed their children with wholesome diet; and yet how unconcerned about the provision for the mind, whether they are furnished with salutary food, or with trash, chaff, or poison?” - Reverend Enos Hitchcock, Momoirs of the Bloomsegrove Family, 1790
Tai Shan
When I found out a baby panda had been born at the National Zoo, I wanted to see him as soon as he was available. Unfortunately, the tickets to see him sold out right away. Now, nine months later, the tickets are largely an unnecessary formality. However, I didn’t know that when Danielle and I woke up at 5 am last Sunday to get a glimpse of Tai Shan. I had read that before 0830 tickets were not necessary to see the Giant Pandas, so I got all my gear ready on Saturday night and set my alarm for 0500. Then we went to go see Tai Shan. I found a group of photographers who all visit at least once a week (some every other day) to see what antics little Tai Shan was up to. He’s currently weaning, so he’s learned that bamboo goes in his mouth, but he still doesn’t eat it as voraciously as his parents. I had no idea I would find him so amusing! I ended up taken nearly 150 pictures of him. In raw mode, that cost me nearly 1.5 GB of space! Below are some of my favorite pictures from that day and I’ll be adding more soon.
Lego Difference Engine
Someone built a difference engine - the first computer ever designed by Charles Babbage - out of Legos. The difference engine is more of a calculator than a computer in that you can’t load multiple programs on it, but it was still extremely revolutionary for its time. In fact, it was only designed on paper and wasn’t actually built until the 1990s!
Here’s the link to the Lego Difference Engine…. raw geekage at its best!
