After *long* sessions (sometimes 20+ hours) with Nethack (http://nethack.org/), I've actually dreamed in terms of @, G, d, h... but then I've had even longer sessions with other games (40+ hours in a weekend) without the same effect, so I'd imagine that's a test of how good the game is at making you feel a part of it.
Needless to say, my near-flawless GPA from high school changed to something like 'barely passing' in college after I discovered games...
I think the 'all browsers' is a bit presumptuous... since the exploit is based on popup windows, browsers like lynx, links, w3m, telnet, your-favorite-lack-of-popup-windows-browser, cannot be susceptible to it.
So I'm inclined to say that it not only *would* be unprecedented, it still is.
The quoted sentence is rather obtuse, but the point is clear: leave behind further attempts at monitoring citizens. To make it less obtuse, it could be written like this:
"... you were not left behind; further attempts..."
Your mangled version of your first question (which is otherwise fine... mostly) does not make sense (ergo, my subject...).
"Does this sentence make sense...?" is a self-referencing question (probably not on purpose), so while it makes sense, it doesn't do what you want it to.
"... to anyone else around here?" implies that you (or someone in the immediate vicinity) understood "this sentence". If it is you who understand it, there's no need for an appropriately-aimed question...
Oh, and if you take off the 'does' from your mangled question, you end up with an implied 'does' in the proper place. Not that 'proper' grammar allows for that...
Very different from GB/(your favorite dedicated console)/(any other game-dedicated machine which relies explicitly on only specific media for game info)... it's a *computer*. CDs, CD drives (or DVDs/drives, floppies/drives, etc.) have limited lifespans and lower transfer rates than the harddrive (except maybe SCSI stuff... but if you have a SCSI CD or DVD drive you've probably invested in a SCSI HDD too...). The only reason I don't use 'CD-cracks' on a regular basis is that I like to be on the legal side of things... otherwise, being forced to use a particular CD in my computer to play a game when my harddrive is sufficient for storage/loading of gamefiles is quite unpalatable.
That's the main reason I rip all my audio CDs to.ogg and only make CDs of those for backups... I've gone through two *dedicated* cd players (boombox-style) in the same time that I've had my current computer and harddrive.
I think the parent should be "+5, funny"... the text of Wanless' Theorem is below.
--- WANLESS' THEOREM
There exist an infinite number of pairs of primes, P and Q, s.t. P-Q=2N, for all N (Corollaries include affirmation of the Twin Prime Conjecture)
Proof: Let p0,p1,p2... be the positive primes, including 1, in inceasing order.
** first off, 1 is not prime... *sigh*
Let Pn=p0p1p2...p(i0-1)p(i0+1)...p(i1-1)p(i1+1)...pn + (p(i0)**j0)(p(i1)**j1)... and let Qn=p0p1p2...p(i0-1)p(i0+1)...p(i1-1)p(i1+1)...pn - (p(i0)**j0)(p(i1)**j1)... [any i, j]
** any i, j? how about i = pi and j = e?
Note that hcf (Pn, p0p1p2p3p4...pn) = 1 and hcf (Qn, p0p1p2p3p4...pn) = 1 [Euclid]
** what does hcf stand for?
Then Pn and Qn are either both prime or Pn is divisible by a prime greater than pn or Qn is divisible by a prime greater than pn
** how, exactly, are Pn and Qn related? oh, and why are we restricted to these three outcomes?
Let n->99999... ** unfamiliar notation...
=> pn->99999... [Euclid] ** unfamiliar theorem
=> Pn and Qn are both prime ** where was this shown? (as opposed to being simply stated)
=> There exist an infinite number of pairs of primes, Pn and Qn, s.t. Pn-Qn=2N [any N>=0] (1) ** true enough, as true as there are an infinite number of primes...
=> There exist an infinite number of pairs of primes, Qn and Pn, s.t. Qn-Pn=2N [any N There exist an infinite number of pairs of primes, P and Q, s.t. P-Q=2N [any N] (3)
** this statement is true, and an echo (possibly to avoid the use of absolute value symbols or other such paraphernalia). unfortunately, it is not the truth the author is after. the desired outcome is to be able to say "for all N, Qn-Pn = 2N has an infinite number of solutions for primes Qn, Pn"; rather, we have arrived with "Qn-Pn = 2N has an infinite number of solutions for primes Qn, Pn, for all N". the one case is quite restrictive, the other, not much.
Corollary (Twin Prime Conjecture): (3) [N=1]
** see immediately previous comment. just because there are infinite primes (what the statement before this one says, in effect) does not mean that for any particular N, there are an infinite number of pairs of primes whose absolute difference is N.

Here's a neat little theorem to describe *all* numbers >1 which are not prime:
k+1 is not prime iff there exist a, b in the positive integers such that k = a*b+a+b
It is a semi-trivial exercise to come up with a similar equation to represent all non-twin-prime pairs. Not that I've been working on it for the last four years or so.:-P IMO, either this or some analytic method are our only ways of really tackling this problem.
(Note that, of course, once you have everything that is not prime, it's pretty easy to pick out those things that are.)
A little extra work here and there might be worth missing a lot of extra work in other places...
if (condition); { var = 8; }
As mentioned previously, it's difficult to see this problem, and a compiler won't flag it (usually...). Plus, using a debugger to step through and find a problem like this would be annoying at best. However,
if (condition) {; var = 9; }
is a 'good' error for at least a couple of reasons:
- you have a no-op instead of killing your conditional
- the book 'Code Complete' (I'm pretty sure that's the one, and possibly others) recommends this as the best format for code (not the extra semicolon, the overall form)
- if you ever find out that there's an extra semicolon hanging around, you can just delete it knowing that it really is a no-op and there wasn't a 'bad' bug there anyways
- if you decide to remove the condition at some later point and comment it out to start the work, it isn't that difficult to do the following:
//if (condition) {;
{
var = 9;
}
Again, only a little bit of work, and the// can be changed from one line to the other without much thought.
Sadly, the coding standard where I work requires the former format. I completely disagree with the 'ugliness' comment... that's a personal opinion that holds little value when attempting to evaluate coding styles. Give me some *reason* that it's ugly, or perhaps your comment should be rated "4, inciteful".
This same logic has been applied a couple times in the thread... the problem with it is that there are ways to make code secure *in the first place* so that viruses/spyware/etc. (maybe not the spyware so much) don't have (as much of) a chance. Windows (or any other OS/program) doesn't have to include an AV program in order to be virus-inhibiting.
I realize that an end-user installing programs willy-nilly (especially as a super-user) will always trump any effort to secure an OS. But if the user doesn't even have a chance to use their OS if their MTTI (mean time to infection) while simply connected to the internet is less than 20 minutes -- I've seen several mentions that it's lower than that these days -- there's no way to honestly blame it solely on the user.
No kidding. I have in my physics book (somewhere...) a section which talks about ways of transmitting power without wires... I believe it was even highly directional/laserlike (or that it was easy to make it so). Not that this would guarantee any sort of efficiency, but imagine having all the electricity needed for anything 'beamed' down from a set of overhead wires or antennae. Granted, there could be known and unknown health risks from having a bunch of current beamed down on us constantly.
"...the number of citations times the [average citation age]..."
It seems to me that this nullifies the comparison in some regards. If you rank by this number DEscending, you get a few old papers with a lot of citations... possibly just because they're old. If you rank by this number Ascending, you get just the newest papers without significant numbers of citations. It might be better to rank by either total numbers of citations or "the number of citations *divided* by the average citation age", and use a DEscending rank. This way, recent works get a 'fair' (or 'fairer') comparison against older works.
Seriously, while Beostein was mildly interesting (I remember almost nothing of it) and Frankenwulf was worth reading so I could know the 'real' story (I remember only a little more of this), they aren't readable for many of the millions of HS students out there. I know there have been 'translations' of various sorts to attempt to 'modernize' books like these so that they are readable, but they don't seem to have taken hold of the main portion of texts that are used.
I've run out of fingers and toes on which to count the number of books I've read in 'electronic' format these days. What's especially helpful is to be able to look up a word in one tab of a web browser while reading in another.
Not that I know the exact diff between 'window manager' and 'windows shell' as it applies to Microsoft, but there are quite a few other... shells (I guess) to replace Explorer with:
Alternatively, a minimal install of linux is under 1gig (redhat 9), and then you just make sure you have a separate partition/harddrive with enough space to do a full-disk backup (or more than one). Then you do a dd from the windows partition to a file in your backup partition for a backup, and another dd to restore the backup.
Given enough space to save more than one backup image, you can do the 'backup at clean install' and 'backup at core install' and restore to either as desired.
There's also a tool (called 'ntfsclone' I think, but it's for ntfs only) that more efficiently does this kind of backup, so you only backup as much space as you are using, not the whole partition.
Penguin-Does (penguin-does.com) is another one in the arena of 'Linux on Windows' programs... I heard that the company behind it has made some pretty good steps towards full X-Windows support, but I still can't rip/play my music CDs with it.
1) ask your boss if you can have a minor snack at your desk
2) if yes, buy a bag of unshelled walnuts to set next to your desk 2a) if no, buy the unshelled walnuts for the break room and have coffee break challenges...
3) every so often, grab an unshelled walnut and break it open with your bare hand. eat the walnut as desired
4) when thirsty, drink water
5) study people's reactions as your handshake becomes amazing
"... the most valuable code in the multi-billion dollar industry..."
Is it just me, or is it valuable only because it isn't publicly available? It doesn't seem that there would be much inherent value in that source code of itself . . .:)
In high school I was never taught anything about network anything (sockets, mailing protocols, etc.). This may be a bit beyond them (or not, since it's AP . ..), but it would probably be good to ask them to write a text-based chat program, maybe give them some pointers to code specifics when necessary, and let them have fun. Essentially, all it would need to do is open a port and listen for another computer to open the same port, then allow the students to chat (text-formatted page?) sort of like the "talk" program in Unix . . .
I haven't read the article yet (yes, yes, I really should develop that habit), but any craft with an orbit around the earth can dangle a wire of significant length (100's of yards to miles) out behind or to the side of them and get a lot of induced current from the earth's magnetic field.
If a survey says all those things this/. article reports, how am I to interpret myself and my surroundings when I don't see any of it? Contrary to immediate thought, I don't "live in a bubble". I work for compaq at the moment on an internship, and I don't see anyone around me who puts in more than 40 hours per week. Few of the people I know anywhere have laptops. Pagers and cell phones are common, but I have noticed only a couple occasions where one or the other interrupted class or a meeting. It may be that there needs to be some sort of employee conspiracy started where the employees all say "we will work this long and no longer." Or it may be that every semblance of work needs to disappear after eight hours. Or . . . but what can *we* do? Each individual ultimately decides how long the work day is, and if that isn't satisfactory, the individual finds a new job or works longer.
------------- "If only life were easy . . . . . . oh, wait, it IS! Everything is black and white, yes or no! Wait, where'd all the color go?"
I noticed several of the points describing the Be operating system, particularly those speaking to the searching and retrieval of information (in the 40's to 50's I think). Be has a fairly well developed internal searching utility, searching any type of file by any attribute. I don't know if text in files can be searched with it, but Be has made a start already it seems.
By the time Yahoo/Geocities has found out and has contacted ALL its members and received a response back from them, the world will have forgotten Unisys, and Y.G. will not have had time to disable GIF's without giving its users fair warning. Then there's TheGlobe, AngelFire, etc etc . . . Having the standards for web pages raised through this would be nice though, and maybe force some development for higher-level animations . . .
