The TCP spec says if a port isn't open the client should get an ICMP error,
Huh? ICMP doesn't relay any information about ports. It's not even part of TCP but a completely different ip protocol. You'll get ICMP redirects or unreachables at layer 3 based on routing, but never based on port.
If a port isn't listening, the destination will reply with a TCP RST. If it's firewalled, most firewalls will silently discard it and the source gets no response their SYN just goes off into the ether. If it's open, the destination will respond with a SYN/ACK.
Other things can be at work here though.. for example, SYN Cookies will SYN/ACK every SYN regardless of service open/closed status, this making all ports appear open to a simple nmpa -sT scan.
Yes, it's a nice perk, but a even nicer perk would be to let everybody at least login through HTTPS. Weren't we bashing companies earlier for not using SSL by default for logins?
Logging in via HTTPS, and using cookies for authentication persistence won't keep anyone with a sniffer from getting access to your account. From getting your password, yes, but not your account.
So, it is possible that, if the executive wanted to be truthful, he or she would say, "I'm not qualified to be in this job, since I don't know enough to understand the company's operations thoroughly."
Really? You think that a CEO of an investment firm should understand the nuances of computer security? That's like saying that the CEO of McDonald's should be able to slaughter a cow.
In tivo's defense... their using NTP for time synchronization. Same thing used by servers the world over, and included in nearly every linux box on the planet. It's not like they invented the wheel or anything, the concept of synching GMT and applying a local offset is nothing new.
Because it gets TIME information from the satellite (in GMT most likely) but then applies your local offset as defined on the box. The offset is controlled programatically, and changes when going from standard time to daylight time and vice versa. Usually, the box knows when to change the offset, but since the DST rules are different this year, that rule needs to be updated on the box.
You're right, the IR blasters are a bit of a kludge. They generally work, but can be subject to the environment and how much IR interference their is, etc.
Tivo also supports using a serial cable to control the box. This works really well on my parents S2 Tivo. MUCH better than the IR Blaster.
You can ALWAYS record analog cable broadcasts without a box. There's a dual tuner Series2 Tivo which allows tuning/recording/watching of two channels at once. Of course, only one of the two can be digital cable unless you rent two boxes, but many people can get by with one digital channel and one analog channel, or two analog channels.
Better still, my new Series 3 TiVo accepts CableCards, which allow me to tune digital channels directly, without a box. It also accepts TWO cablecards, so I can record two HD streams at once. Brilliant!
That's not going to be a lossless transfer of energy though. And you still have to prime it initially somehow.
High-tension springs seem to be something I wouldn't want to have attached to my body during combat anyhow. Ever seen the damage a garage-door spring can do if it unleashes all it's energy at once, or fails catastrophical?
Maybe there are other ways, but I'm not convinced springs are one.
We can assume no group even remotely competent enough to even get into this hypothetical security "protection" business in the first place would be stupid enough to let possibility one happen. This leaves possibility two. See the problem?
While I largely agree with your point, the quoted line made me think of this;
Man in black: [turning his back, and adding the poison to one of the goblets] Alright, where is the poison? The battle of wits has begun. It ends when you decide and we both drink - and find out who is right, and who is dead. Vizzini: But it's so simple. All I have to do is divine it from what I know of you. Are you the sort of man who would put the poison into his own goblet or his enemies? Now, a clever man would put the poison into his own goblet because he would know that only a great fool would reach for what he was given. I am not a great fool so I can clearly not choose the wine in front of you...But you must have known I was not a great fool; you would have counted on it, so I can clearly not choose the wine in front of me. Man in black: You've made your decision then? Vizzini: [happily] Not remotely! Because Iocaine comes from Australia. As everyone knows, Australia is entirely peopled with criminals. And criminals are used to having people not trust them, as you are not trusted by me. So, I can clearly not choose the wine in front of you. Man in black: Truly, you have a dizzying intellect. Vizzini: Wait 'till I get going!!...where was I? Man in black: Australia. Vizzini: Yes! Australia! And you must have suspected I would have known the powder's origin,so I can clearly not choose the wine in front of me. Man in black: You're just stalling now. Vizzini: You'd like to think that, wouldn't you! You've beaten my giant, which means you're exceptionally strong...so you could have put the poison in your own goblet trusting on your strength to save you, so I can clearly not choose the wine in front of you. But, you've also bested my Spaniard, which means you must have studied...and in studying you must have learned that Man is mortal so you would have put the poison as far from yourself as possible, so I can clearly not choose the wine in front of me! Man in black: You're trying to trick me into giving away something. It won't work. Vizzini: It has worked! You've given everything away! I know where the poison is! Man in black: Then make your choice. Vizzini: I will, and I choose...[pointing behind the Man in black] What in the world can that be? Man in black: [turning around, while Vizzini switches goblets] What?! Where?! I don't see anything. Vizzini: Oh, well, I...I could have sworn I saw something. No matter. [Vizzini laughs] Man in black: What's so funny? Vizzini: I...I'll tell you in a minute. First, lets drink, me from my glass and you from yours. [They both drink] Man in black: You guessed wrong. Vizzini: You only think I guessed wrong! That's what's so funny! I switched glasses when your back was turned! Ha ha, you fool!! You fell victim to one of the classic blunders. The most famous is never get involved in a land war in Asia; and only slightly less well known is this: Never go in against a Sicilian, when death is on the line!
[Vizzini continues to laugh hysterically. Suddenly, he stops and falls right over. The Man in black removes the blindfold from the princess]
"If I tell you negative information, you'll know less."
This is nothing new, the effect is known as 'the dumbening.' It can be easily reproduced in the home by watching Harold & Kumar go to White Castle. Watch that movie, and I guarantee you'll know less!
While you can say PETA is a great thing, and I personally might agree with you, it's never going to be a viable business model to save the kittens (or mink, if you want to be more direct.)
Tell that to the companies that make cosmetics which aren't tested on animals. Ask the organic produce growers how profitable their business is. Ask the people who make Pleather if they're able to survive despite making an animal friendly product. Check out the companies who make biodegradable diapers. Look into Boca's profitability.
There's plenty of businesses who manage to turn a tidy profit, largely due to their 'save the kittens' business model. Many people will pay a premium for products that don't harm animals, and taking advantage of that is a very real business model.
I agree that we need to encourage energy conservation. It'd ridiculous that nearly every day when I leave my office, 80% or more of the lights in the building are on. When I come back in the morning, those SAME lights are STILL ON. I've tried turning them off, only to find that the cleaning people turn them on and then never turn them off.
I know my case isn't unique. Even late at night on weekends, one only needs to glance to the side of the freeway to see the rows of highrise buildings all aglow in artifical light. I can't believe that many people are putting in such long hours. It's as if energy has 0 cost, financially and environmentally. Maybe if taxes were increased it would encourage businesses to be more thrifty with regards to energy uses.

How exactly did they manage a misspelling in an "online video-taped message?"
Or was it the editor that mispelled, in which case, why quote a single word with no context?
