Yes, the T61 has FireWire, can be equipped with an integrated webcam, and has optical audio/DVI through the dock if you need it.
Let's not forget that the T61 also has available WWAN, a hot-swappable optical drive (or you can add another battery / hard drive), more pointing options (eraser/touchpad, two buttons for each), a better keyboard, and is quieter.
Here are the possible game outcomes, under the switch strategy:
Outcome A (TD1 MG2): Contestant chooses door with goat #1, Monty reveals goat #2, WIN Outcome B (TD2 MG1): Contestant chooses door with goat #2, Monty reveals goat #1, WIN Outcome C (TDC MG1): Contestant chooses door with car, Monty reveals goat #1, LOSE Outcome D (TDC MG2): Contestant chooses door with car, Monty reveals goat #2, LOSE
Now, we will establish some conditional probabilities: P(X|Y) means "the probability of X given that Y has already occurred"
P(MG2|TD1) = 1 (Monty MUST reveal goat #2 if contestant chooses goat #1; he cannot reveal the car or the door the contestant selected) P(MG1|TD2) = 1 (Monty MUST reveal goat #1 if contestant chooses goat #2; he cannot reveal the car or the door the contestant selected) P(MG1|TDC) = 1/2 (Monty reveals goat #1 or goat #2 with equal probability if the contestant selects the car) P(MG2|TDC) = 1/2 (Monty reveals goat #1 or goat #2 with equal probability if the contestant selects the car)
Now, some simple probabilities for the initial choice:
P(TD1) = 1/3 (Contestant chooses any door with equal probability) P(TD2) = 1/3 (Contestant chooses any door with equal probability) P(TDC) = 1/3 (Contestant chooses any door with equal probability)
So, let's review the outcomes now that we know their probabilities:
Outcome A (TD1 MG2): Contestant chooses door with goat #1, Monty reveals goat #2, WIN (Probability 1/3) Outcome B (TD2 MG1): Contestant chooses door with goat #2, Monty reveals goat #1, WIN (Probability 1/3) Outcome C (TDC MG1): Contestant chooses door with car, Monty reveals goat #1, LOSE (Probability 1/6) Outcome D (TDC MG2): Contestant chooses door with car, Monty reveals goat #2, LOSE (Probability 1/6)
Let's find the probabilities of winning and losing:
X Y means EITHER X or Y occurs. P(X Y) = P(X)+P(Y) if X and Y are mutually exclusive (this is a probability theory axiom) All four of our outcomes are mutually exclusive (they CANNOT occur at the same time)
Under the "switch" strategy, you have a 2/3 chance of winning and a 1/3 chance of losing.
Everything I just wrote is basic probability and set theory, usually taught within the first 2-3 weeks of a college-level introductory probability course.
Bullshit. My 2.5GHz Penryn is faster than this thing.
This POWER6 has two 2-issue in-order cores at 5GHz. My Penryn has four 4-issue speculative out-of-order cores at 2.5GHz.
That means that my Core 2 can retire, theoretically, 40 billion instructions per second (4 cores, 4 issue, 2.5GHz).
This CPU can retire, theoretically, 20 billion instructions per second (2 cores, 2 issue, 5GHz).
In reality, neither CPU gets anywhere close to that because real code has data dependencies, branches, and other pipeline hazards.
Every few years, someone comes along and claims that they can make a faster CPU by "eliminating the complexities of out-of-order execution". Intel tried with Itanium. IBM is trying with POWER6. But it doesn't work. Some code, with some compilers, can run very fast on an in-order CPU. But once you throw code that is branch-happy or has lots of data dependencies at the compiler, it goes and pisses all over itself. That's why you don't usually see in-order designs that are more than 2-issue.
Intel claimed that compiler technology would make up for the in-order nature of the Itanium. Like POWER6, it has lots of transistors and lots of cache.
That stuff may make POWER6 a good CPU in some applications. And unlike Itanium, POWER6 has high clocks to make up for reduced IPC. But the fact remains that this is a dual-core, in-order CPU in a quad-core, out-of-order world.
To be perfectly frank, that's probably a design issue on HP's part. My HP 6910p gets around 5 hours with Vista on the 6-cell battery, and that's with a 2GHz Core 2, 7200rpm drive, and 14" widescreen LCD.
This system, with a slower VIA CPU and a smaller screen should be able to get at least half the battery life with half the battery size.
In Orange County, CA there are literally hundreds of boxes with AT&T on them being installed on the sides of streets. They are working on them continuously. I assume that is FIOS going in, and they are really working hard, it's *everywhere*.
The only problem with your assumption is that FIOS is Verizon, not AT&T.
Now, AT&T is deploying FTTP and FTTN, but it's not branded as "FIOS". Now if only Qwest would get their act together.
Better driver support is reason enough for me to use Vista 64 vs. XP64. And 64-bit support is becoming increasingly relevant as memory continues to get more and more affordable.
It's not only the geeks who turn their noses at the new MS-OS. It's a general sentiment.
This, my friend, is bullshit. The pundits want you to think that, but the fact is that the vast majority of people using Vista don't care one way or another. Vista is just another version of Windows that they got on their hardware.
Mossberg and Pogue don't represent the general public. Neither do enterprise customers who are slow to migrate, as usual (many of who have now done so or will do so soon).
The reality is that no matter how much people trash Vista, it's just not that bad of a product. Ask the 14% of computer users who boot up Vista every day.
Also, Adobe has to have a 64 bit version for Windows, because Windows comes in 64- and 32- bit versions, but OS X has the same support for both 64- and 32- bit in the same OS...
Photoshop CS2 (32-bit) runs fine on Vista 64.
You want a 64-bit Photoshop for one reason: it can use more than 4GB of memory.
In fact, I recently took an informal survey of about a dozen CS seniors and found that none (yes, none) of them knew what K&R, the "white book", or the "Art of Computer Programming" were.
Why the hell should they? Is knowing the title of a C book that's out of date (OK, the second edition is better, but K&R usually refers to the original edition) important?
Perhaps you don't understand what CS is. CS isn't about C - in fact, it's not even about programming at all. CS is about the theory of computation. Things like programming language theory and computational complexity theory are subsets of CS.
CS doesn't include coding practices, use of source control, project/time management, or software testing. All of that is part of software engineering.
The problem is that people expect CS programs to produce functional software engineers. And while functional software engineers certainly need a strong grasp of theoretical concepts (such as a basic computational complexity theory and common algorithms), what they really need is software and systems engineering experience.
No, they are all Apple's fault. When you make the hardware and you make the software, people expect compatibility. Apple even advertises this as an advantage.
Um, in Windows Vista, it's called "Users\YourUserName". Documents is just one subdirecrtory of your home directory.
Application configuration information goes in a folder called "AppData". Registry information is also stored in your user profile, also under your home directory.
Poke around Windows and you'll find that the taskbar obeys Fitts' Law.
Here's a question, though. Fitts' Law says that the time to access an object depends on BOTH the distance from the pointer and the size of the object.
The Mac OS menu bar may be infinitely large, but the bigger your screen gets the further away it gets from the work area. And even if you think that the time to access the menu is low (which it may be), the time to RETURN from the menu to doing other work becomes increasingly large.
Context-sensitive (right-click) menus are particularly attractive according Fitts' Law, but they are terribly underutilized on the Mac.
Right on. I'm on Fast Ethernet here in the dorms at the University of Colorado, and there gigabit uplink from the IDF (in my building) to the housing core router, which has a 10 gigabit uplink to the main campus routers.
I can saturate the connection when I hit Akamai, because we have a mirror on campus. Other campus connections are fast, because of Internet2.
But you know what? 6-megabit Comcast "feels" as fast - if not faster - most of the time. The latency is better (around 35ms to Google), for one. And unless you're downloading gigabytes of data, you'd never notice the difference. At least not unless you use BitTorrent (one reason no one I know has Comcast anymore).
Can someone tell me how my friend's $35/mo 7-Mbps DSL is so terrible? How we're "losing our edge"? The way I see it, the Internet is pervasive here, if you want it. The fact that my grandparents don't want to spend $40/mo for broadband they wouldn't use anyway doesn't prove anything.
Things like reliability, packet loss, and latency matter FAR more than the number of "megabits" your connection has. Bandwidth doesn't mean dick if you can't use it.
Unfortunately for your position, the current mainstream scientific theory is that the universe was created at a specific time in the past. In fact, the whole point of this article is that time just got even more specific.
Unfortunately for your position, the current mainstream scientific theory doesn't specify that the Big Bang is the "beginning of everything", just the beginning of our present universe.
Watch the video of the announcement yesterday. The Exchange compatability is the best I've ever seen.
You mean outside of Windows Mobile DirectPush, which does everything that the iPhone does and more?
I'm glad to see Exchange support on the iPhone, but let's not pretend here. The things they licensed from Microsoft were already supported by Windows Mobile anyway, and have been supported for some time now.
That's the current reality, but even The Supreme Court can be wrong in interpreting the law.
Whether or not they are wrong is irrelevant. The Supreme Court has held that the Bill of Rights applies to state laws, whether you like it or not. And the states can't have laws that the Supreme Court has found to be unconstitutional.
Most people expect Microsoft to make a similar move.
Microsoft DID make a similar move, in 1998, when the introduced Authenticode. Vista checks the signature on applications before elevation. Even XP will check the signature on stuff that you downloaded off the Internet.
Apple is WAY BEHIND on code signing. Here's a hint: just about every system executable and library file on Vista is signed, as are most of the executables on XP.
AMD is in competition with Intel ATI is in commpetition with Nvidia AMD + ATI is in competition with INTEL
First, AMD and ATI are the same company, and the company is named AMD. ATI is a brand used for AMD's graphics solutions. Second, AMD and NVIDIA are very much in competition, both in discrete graphics AND in core logic (chipsets).
In fact Intel has more market share then ATI and Nvidia combined.
Incorrect. AMD and NV both have around 28% of the market, Intel has about 40%, and the balance is controlled by VIA and other players.
This "vulnerability" is basically irrelevant for notebooks. Most notebooks have hot-swappable CardBus or ExpressCard slots, both of which have DMA support and can be used to dump the system's memory. Or you could do the "memory freeze" trick.
The correct solution would be to map the FireWire address space into virtual memory, but this has to be done at the hardware level.
FastCGI is also available as a free add-on for IIS6 (WS2003) from Microsoft, and I can confirm that it works quite well. I'm seeing 3-4x more requests per second in my stress testing using IIS/WS2003 compared with a similarly configured Apache 2.x server.
This is comparing Apache 2.2 in mpm-prefork mode with mod_php to IIS6 with FastCGI.

Last time you looked at how CPUs worked, you failed.
Modern CPUs do not run at bus speed, which is the figure that you are quoting. There is a clock multiplier.
Some of AT&T's U-Verse deployments have been FTTP, such as in Oklahoma City:
http://www.dslreports.com/comment/2956/60809
You are correct that most of the deployments have been FTTN. Qwest is also pursuing a similar strategy, albeit at a slower pace.
Give it up. Conditional probability supports the conclusion that you are better off by switching:
Let's define some events:
TDC = Contestant chooses door with car
TD1 = Contestant chooses door with goat #1
TD2 = Contestant chooses door with goat #2
MG1 = Monty reveals goat #1
MG2 = Monty reveals goat #2
Here are the possible game outcomes, under the switch strategy:
Outcome A (TD1 MG2): Contestant chooses door with goat #1, Monty reveals goat #2, WIN
Outcome B (TD2 MG1): Contestant chooses door with goat #2, Monty reveals goat #1, WIN
Outcome C (TDC MG1): Contestant chooses door with car, Monty reveals goat #1, LOSE
Outcome D (TDC MG2): Contestant chooses door with car, Monty reveals goat #2, LOSE
Now, we will establish some conditional probabilities:
P(X|Y) means "the probability of X given that Y has already occurred"
P(MG2|TD1) = 1 (Monty MUST reveal goat #2 if contestant chooses goat #1; he cannot reveal the car or the door the contestant selected)
P(MG1|TD2) = 1 (Monty MUST reveal goat #1 if contestant chooses goat #2; he cannot reveal the car or the door the contestant selected)
P(MG1|TDC) = 1/2 (Monty reveals goat #1 or goat #2 with equal probability if the contestant selects the car)
P(MG2|TDC) = 1/2 (Monty reveals goat #1 or goat #2 with equal probability if the contestant selects the car)
Now, some simple probabilities for the initial choice:
P(TD1) = 1/3 (Contestant chooses any door with equal probability)
P(TD2) = 1/3 (Contestant chooses any door with equal probability)
P(TDC) = 1/3 (Contestant chooses any door with equal probability)
Now, using the law of conditional probability:
P(MG2|TD1)=P(TD1 MG2)/P(TD1) -> 1 = P(TD1 MG2)/(1/3) -> P(TD1 MG2) = 1/3
P(MG1|TD2)=P(TD2 MG1)/P(TD2) -> 1 = P(TD2 MG1)/(1/3) -> P(TD2 MG1) = 1/3
P(MG2|TDC)=P(TDC MG1)/P(TDC) -> 1/2 = P(TD2 MG1)/(1/3) -> P(TDC MG1) = 1/6
P(MG2|TDC)=P(TDC MG2)/P(TDC) -> 1/2 = P(TD2 MG1)/(1/3) -> P(TDC MG2) = 1/6
So, let's review the outcomes now that we know their probabilities:
Outcome A (TD1 MG2): Contestant chooses door with goat #1, Monty reveals goat #2, WIN (Probability 1/3)
Outcome B (TD2 MG1): Contestant chooses door with goat #2, Monty reveals goat #1, WIN (Probability 1/3)
Outcome C (TDC MG1): Contestant chooses door with car, Monty reveals goat #1, LOSE (Probability 1/6)
Outcome D (TDC MG2): Contestant chooses door with car, Monty reveals goat #2, LOSE (Probability 1/6)
Let's find the probabilities of winning and losing:
X Y means EITHER X or Y occurs.
P(X Y) = P(X)+P(Y) if X and Y are mutually exclusive (this is a probability theory axiom)
All four of our outcomes are mutually exclusive (they CANNOT occur at the same time)
P(WIN) = P(A B) = P(A)+P(B) = 1/3 + 1/3 = 2/3
P(LOSE) = P(C D) = P(C)+P(D) = 1/6 + 1/6 = 1/3
Under the "switch" strategy, you have a 2/3 chance of winning and a 1/3 chance of losing.
