40 digits of pi should be enough for anyone. That's all the digits you need to calculate the size of a spherical Universe with a radius measured in Planck lengths. Beyond that it's just mathematical masturbation.

Happy Pi Day

Nah, the true logical order is a fully specified ISO 8601 compliant date, ordered as year, two-digit month, two-digit day, so the first pi day will be 31 415 926 535 897 932 384 626 433 832 795 028 841 971 693 993 751 058 209 749 445 923 078 164 062 862 089 986 280 348 253 421 170 679 821 480 865 132 823 066 470 938 446 095 505 822 317 253 594-08-12 (August 12).
That's roughly 314,159 googol-googol A.D. Like a thousand-thousand being a million, except much bigger.
But if you really want to get picky, you want the pi second: ten consecutive digits in pi matching the constraint of month, day, hours, minutes, and seconds in MMDDhhmmss format. That's July 26, 02:49:14. Treat the preceding 288 digits as the year and everything thereafter as an irrational fraction of seconds.
I'll leave as an exercise to find out what day of the week those two dates are. But I seriously doubt our calendar will still be in use by then, let alone our Universe.
Thanks go to The Pi-Search Page for the technical assistance (position 287 excluding the leading 3).
But adding a little extra item to the main menu? That's nothing. A little thing on their "you're done with this program, now what?" screen? Fine with me. The little "pop-ups" during commercials? Also doesn't bother me.
You forgot the ones at the end of the list of shows gathered together in groups, but you may be watching your shows before you end up with two or more unwatched. I was delaying watching Lost so a friend could catch up. There was an ad entry at the end of the group of recordings in the Now Playing list.
Do they charge you a monthly fee? Yes. Totally worth it. For that you get software updates, guide data, suggestions (which is what's most valuable).
I find I don't peruse the suggestions much. Regular TV spots clue me into new series well enough, except when they're advertised with reruns and premiere simultaneously with new episodes instead of waiting a week to premiere (e.g. "Spectacular Spider-Man").
Also, changes forced upon us by Time Warner Cable has made their cable boxes incompatible with TiVo's Suggestions engine and Series1 TiVos. They're prone to mis-tuning and crashing if channels are changed on the minute their internal guide data would update. TWC is at risk of losing their local contracted monopoly over subjecting this city to their beta-test software without informing their customers.
the downloadable shows (like The Onion videocast)
Oh, if only the audio podcasts were downloadable in the same way, or I could pick video podcasts from other sources. Also, some of those video podcasts have been having glitches. "Indy Mogul" has had bad audio sync and even severe jitteriness like they got the interlacing completely wrong (though I've seen that on premium movie channels, once on an independent foreign film), or the download ended with minutes of slug at the end, or ended prematurely. One "Rocketboom" was mere seconds long and could not be redownloaded (prob. due to depicting the AACS key in mirror image on a T-shirt). And timeliness is lacking. "GeekBrief.tv" often comes in bursts of episodes out-of-order and "DL.TV" episodes have come almost a month late.
As for the YouTube feature? Kinda neat. I'll probably never use it. The only feature I'd like at this point is Netflix integration (especially HD movies). But that won't happen any time soon. I'm happy.
They'll need a complete browser implementation I think to get it working. And with that, a USB dongle for use with a Bluetooth keyboard as both of the Ouija boards built-in can be annoying to use for extended periods (and certain useful shortcuts like PageUp to jump from the board to the list of shows no longer work).
I haven't used their Amazon service. I still like owning content permanently.
If you're on the Mac... they've forgot about you. It's sad. I'm on a Mac, and it annoys me. I used to be able to use TiVoDecodeManager (which was awesome), but that seems to have broken with Leopard. You could pay $100 to get some piece of junk from Roxio... but at least the option is there.
I've been using the Roxio solution. It seems to work, though for some reason it won't transfer the recent Knight Rider TV movie to the Mac. It'll start, then abort the transfer. Neither of two showings will transfer. It's broadcast TV, and they're not flagged; it should transfer. I haven't had this trouble with other shows.
I do wish the TiVos had the computer's ability to auto-transfer shows between them as they arrive. It could be close enough to cooperative scheduling to satisfy power users, leaving units headless just to tune and transfer to a system with 2 TB of storage. But then there's the mandatory copy protection on CableCard-recorded content and almost every video podcast ("GeekBrief.tv" almost always allows transfer).
TiVo has some expenses that could go away. They have to maintain dial-up accounts for all the boxes to dial in on (they have UUNet do that for them, IIRC
How do you know what to buy from that colony? The first thing is to buy part of the colony so that you have a local outpost that can negotiate in local currencies and build local capital. Populate it with people who would be valuable assets there but redundant and a drain on your resources back home.
How would you design a probe short of magic to extract, refine, test and smelt an arbitrarily large number of metals without those pieces taking up a significant portion of the payload? Really big space-borne electromagnets to assist in or directly to pull it out of the gravity well into orbit, tethering to a large natural satellite (or suitable relocated asteroid) as a counterweight.
Or just rail-gun it into orbit. Then divert it to your near stellar orbit refinery to take advantage of that natural furnace, then rail-gun it back out to your fabrication platform.
If dealing with a substance that doesn't impel well with magnetism, encase it in something that does.
Firefox spell-check agrees: two Ns, one L in "tunneling". Further, no ambiguity is introduced by not doubling the L.
It's a peculiar Americanism. There is robbing, but there's also robing as in the opposite of to disrobe. Raping and rapping are formed from rape and rap respectively, so there's where ambiguity steps in to set the rule. However, it is impelling and not impeling, or even compelling and not compeling. Is it the rule to limit how many repeated adjacent letters you have in a word? There's potterring (Brit.) and pottering (US) but there is only puttering and not putterring anywhere?
For me, it's trust the spell checker, but when in doubt verify. I'd rather have consistent rules, but English is such a mongrel language anyway, borrowing words everywhere. It's annoying, but at least it isn't annoyying.;D
Early on, some people were hosting the images on their websites using ftp URLs instead of http URLs. Browsers with FTP support were adhering to the social norm that, when logging in to an FTP site as "anonymous", the user was to send his e-mail address as the password. (Some FTP sites would deny access to anonymous logins if the domain in the password didn't match, but would accept "username@" as implying that the domain was consistent.)
This was a quick way to illicitly harvest web surfers' e-mail addresses, and was why I never gave a browser my e-mail address and instead always used dedicated e-mail software to read e-mail, preferably something that also wouldn't open any connections to download data for any embedded content in HTML e-mails like images, frames, iframes, java applets, javascripts, flash content, etc.
Dude, don't you know that it's Slashdot-hip to be ultra-paranoid about absolutely everything? Picking and choosing your encryption needs based upon, gasp, practicality and with an eye toward efficient use of your technological resources isn't going to win you any points around this place. I don't say any more until the CSM-25 counter measure filter is activated.
Something is messed up wrt moderation of Anonymous Cowards. I grant one point to ACs so they should start at 1 instead of 0 for me, but I'm also seeing "Score: 0, Funny" on some AC postings with no other moderations applied than one +1 Funny mod. It's like the first mod up lowers the initial score.

Hmm, scp has built-in support for transfering an entire directory with one command natively, but sftp can be used to transfer files between two servers while being controlled from a third site such that the transfer doesn't pass through the controlling client (useful for maintaining from a dial-up connection two high-speed servers that don't grant shell access).
Also, answering with the person's name eliminates an identity confirmation opportunity. Hell, I expect the place where I order pizza delivery to know my name and associate my phone number from Caller ID to my name automatically, but I'd like them to take notice if someone else orders a pizza from my phone and the names don't match.
Not that if someone broke into my home or faked the CLID to order pizza wouldn't know my name, or that they'd even care. But leave the opportunity for a stupid criminal to be stupid:
The phone rang. He stopped the tape and answered it, then almost dropped the phone like an electric eel as he realized what he was doing. Hardly daring to breathe, he held the telephone to his ear.
"Rule One in housebreaking," said a voice. "Never answer the telephone when you're in the middle of a job. Who are you supposed to be, for heaven's sake?"
Richard froze. It was a moment or two before he could find where he had put his voice.
"Who is this?" he demanded at last in a whisper.
"Rule Two," continued the voice. "Preparation. Bring the right tools. Bring gloves. Try to have the faintest glimmering of an idea of what you're about before you start dangling from window ledges in the middle of the night.
"Rule Three. Never forget Rule Two."
"Who is this?" exclaimed Richard again.
The voice was unperturbed. "Neighborhood Watch," it said. "If you just look out of the back window you'll see..."
Trailing the phone, Richard hurried over to the window and looked out. A distant flash startled him.
"Rule Four. Never stand where you can be photographed.
"Rule Five... Are you listening to me, MacDuff?"
"What? Yes..." said Richard in bewilderment. "How do you know me?"
"Rule Five. Never admit to your name."
Richard stood silent, breathing hard.
"I run a little course," said the voice, "if you're interested..."
Richard said nothing.
"You're learning," continued the voice, "slowly, but you're learning. If you were learning fast you would have put the phone down by now, of course. But you're curious - and incompetent - and so you don't. I don't run a course for novice burglars as it happens, tempting though the idea is. I'm sure there would be grants available. If we have to have them they may as well be trained.
Yes. And the Nestors with intact first laws were convinced by a Nestor with a modified first law that they need not rush to the aid of a human in a futile attempt to save him. You then had 62 robots that would not rush into the high radiation area to save a human who entered the area, but had intact first laws.
Thus the reason for manufacturing those with the modified first law was negated and unmodified Nestors could be used.
Alternatively, as per the final experiment, the robots could have received other training that told them the radiation was not harmful to humans, and again they would not rush to the human's aid due to ignorance.

Then to finally read the first three chapters of Salmon of Doubt was a double blow, because it was shaping up to be one of his finest books./sob A pity though that a rhinoceros in a swimming pool had been done, though not nearly as well. It was a masterful chapter, a personal favorite.
The quotes from the book "Life, the Universe, and Everything", first Marvin:
"I gave a speech once," he said suddenly, and apparently unconnectedly. "You may not instantly see why I bring the subject up, but that is because my mind works so phenomenally fast, and I am at a rough estimate thirty billion times more intelligent than you. Let me give you an example. Think of a number, any number."
"Er, five," said the mattress.
"Wrong," said Marvin. "You see?"
The mattress was much impressed by this and realized that it was in the presence of a not unremarkable mind. It willomied along its entire length, sending excited little ripples through its shallow algae-covered pool. And then Eddie:
When it became clear that Prak could not be stopped, that here was truth in its absolute and final form, the court was cleared.
Not only cleared, it was sealed up, with Prak still in it. Steel walls were erected around it, and, just to be on the safe side, barbed wire, electric fences, crocodile swamps and three major armies were installed, so that no one would ever have to hear Prak speak.
"That's a pity," said Arthur. "I'd like to hear what he had to say. Presumably he would know what the Ultimate Question to the Ultimate Answer is. It's always bothered me that we never found out."
"Think of a number," said the computer, "any number."
Arthur told the computer the telephone number of King's Cross railway station passenger inquiries, on the grounds that it must have some function, and this might turn out to be it. And in this case, Eddie was responding directly to Arthur's query about the question and answer.
And it is so Douglas Adams' style to tell you something at the start of a book and bring it back for the very end. He did it again in "Mostly Harmless" wrt Stavro Mueller and his clubs. He did it in "Dirk Gently's Holistic Detective Agency" with the sofa. IIRC, even the computer game for THHGTTG requires that you do something very early in the game just right or else you can't finish it.
Sadly, Eddie's line, "Think of a number, any number," didn't make it in to the completion of the radio series.
"The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
If they need someone's files to convict someone else, they can grant immunity for anything found in those files that may incriminate the owner to negate the Fifth Amendment barrier.
However, they still have sneaky tricks, like only granting immunity at the state level and not federal, or not international so you're effectively barred from travel to certain countries for, say, having cartoons of a particular religious leader. And they'll still put you on their radar in case you acquire any similar incriminating thing later, which will be a separate crime(*). And then there's that whole confiscation issue too.
(*) I don't think "fruit of the poisonous tree" applies. If someone with immunity testifies to a murder, it's a matter of public record and that person will still be looked at as a suspect for other, similar murders. Immunity does not grant freedom from suspicion. Further, you can be compelled to testify if granted immunity from prosecution even though testifying will still get you killed; witness protection is not perfect nor is it a cushy life forever. Nor does prison for contempt for refusal to testify guarantee continuity of your life.
Unless there's some way to make disclosure under an evidentiary seal requiring anything self-incriminating be treated as it never existed. And reality still just doesn't work that way.
My prof had a test for my engineering problems class. He gave us a bunch of questions that we had to answer, and we could do whatever we wanted in the classroom, but we couldn't talk to each other.
