The reason for using FTP is a metric for long-lived connections, or connections that will transmit lots of data. It's not because FTP is or not obsolete, it applies to SCP or downloads through http (like those ISO files many download).
So, no, it's not related to TCP but in the sense of transmission of lots of data during a single connection.
In fact, although many routers and switches have level 4 (transport) capabilities those are still level 3 (routing) and level 2 (data link) equipment, and that should be transparent to them.
They should, in fact, start supporting ECN instead of changing TCP. Implementing ECN altogether with a well tuned AQM can reduce packet losses and difference packet losses due to congestion from those due to medium (now more important with so many wireless networks). Then, they can start looking for TCP versions that can react to congestion in a different way to the way they react to packet losses.
You know I always thought that those messages were meaningful in the sense of notifying the user they need to get new toners or cartridges soon. Same with laser printers, you never take a toner out when the printer says (out of toner) when you know you can "shake" it a little bit and use it for lots of copies.
So printer manufacturers should only notify users with: "Your toner/cartridge is going to be empty soon, you better get one if you want to keep printing. If you already bought one, just wait until this one is over"
I couldn't agree more. The perfect phone depends on personal needs and that's a complicated thing to accomplish... get all the personal needs together.
In fact, for me the cellphone as it is right now, doesn't have the right approach. You have a phone with a bluetooth headset. The future phone (at least in my dreams) will be a headset in your ear and you'll have your input devices (keyboards, small key pads) and output devices (screens, your sun glasses) connected to any wireless technology (yes, not necessarily bluetooth).
So if someone thinks that the phone should be thin so it will fit on your pocket, I think it shouldn't go in your pocket. And the versatility of exchangeable input/output devices can fit more people than just this guy's dream (i.e. your qwerty keyboard).
Of course not! However, DSL will not work if you don't have wires... and of course are you putting them? Then you better pay for them! And I never heard of a DSL working stand alone... you MUST have a phone line, and long distance is imperative if you want to connect to websites around the globe. Everything makes perfect sense!
I have to add that some people also think they can do "work" from inside their cars. Either talking to a co-worker inside the car or on the phone, phone conferences. I mentioned in other post, that brainless conversations, or simple tasks that do not require most of your attention are harmless.
A recent friend told me in his country, text messages are more expensive than cell phone calls, therefore people tend to use there handsets more to send messages than talking.
I just can't imagine stupid people having conversations using text messages, while driving but there are lots.
I'm certainly sure that I'm so bad driving while on the phone, that I normally have to slow down, and use the handsfree. However, what i've seen is that it mainly depends on the topic. If you're talking stuff that keeps to from paying attention to the road, certainly you'll make mistakes. If you're taking just silly stuff or saying hi to a friend (some brainless conversation), doesn't take much of your concentration off.
What I think is worst is, that some countries (and probably next in the US), the text message system popularity has grown so much, that some people believe they are skilled enough to type messages while driving. Some of them, because it's cheaper send messages (in other countries), some others, because they "don't want to get caught" by the cops.
Isn't better just get a camera with built-in WiFi?
As soon as your 2G are not enough, then what? buy another one? The memory will still need power coming from the device it is attached to. Why not, just add WiFi to the devices from now on? (Which I think is what is happening anyways).
Well then, that is a good indicator that you are in the wrong neighborhood. However, there's always a way to keep track of the computers using your network.
The only reason I have my network protected, is because I don't want to do all that security thing of encrypting, keeping logs. If I weren't lazy enough, I'd keep logs as future support and keep the network open.
1. Why can't Router manufacturers make WPA the default and use "no security" instead?
I say, why WPA, why not WEP or 802.1x? Because everything is based on Drafts not standards so everyone does what they want.
2. Why can't we get the information just how far away the "full bandwidth" works, instead of finding out without fail that most APs can hardly provide the promised bandwidth over distances more than 5 yards?
That mainly depends on both your router and your network card, therefore it's quite complicated to know exactly these distances. You might as well buy a 1W router and radiate everyone around you. They are only US$1000+
3. How long 'til we can't use WiFi anymore because all frequencies are already taken by your neighbors and the companies around you? Worse, can you soon be forced to discontinue your WiFi use because the company next door needs your frequency? (Because, yes, it's unusable past 20 yards but can easily interfere with networks a few miles away, it seems)
Frequencies around 2G are not licensed, reason why cordless phones and later WiFi routers were put into that range. As long as you don't radiate too much power, it shouldn't be a problem. You can switch among (at least) 3 non-interfering channels or 11 channels in total, without counting on the SSID. Of course the more devices you have attached, the worse the performance (which takes you again to your 2nd question).
What it comes to my mind is, WHY people keeps using SSIDs like "linksys" or "netgear", and the really poor implementation of the wireless connection managers in MAC and Windows (Linux is primitive, but at least does what you want).

Well, why not.. a "multi-touch-display"?

But that's just my thought.
You mean you are aiming for the "gynecology" section and how you can provide significant support in that area.
As a slashdotter, I think we all know, with every single detail, the "theory".
This is not about incompatibility, it is just a simple excuse to tell you: You are not worthy.
Jobs' creation isn't just for everyone.
(note you might find that the poster is not allowed to drink from the holly grail either).
You missed the official rules.
Wow, I hope you can be modded +100. Too bad I wasted my points on useless comments :(
People who wrote this probably think that scientific research is a process most resembling folding a stack of envelopes.
It seems you are forgetting they work for the government. Perhaps that's all they do besides bothering anyone else.
Well, I bet if you put it on the washer for a couple of times, little fibers will be safely polished.
By the way, is it washer safe?

Interesting, a little bit more of information and beautiful pictures can be found on the page of the Dryden flight research center: SR-71 and YF-12
And more than 100mW of power, and not just a bit more.
That's what I thought. Then Google just want to reduce the costs of having Google Vans around the cities taking pictures.

Stupidity is really amazing!
Let me back it up, just in case something is missing.
If it is the case, I can restore the backup on another RAM and re-send it to you.
Maybe they can get you some karma points on slashdot! :)

Just give one to Paris Hilton. That should entertain us for some days. :)
Currently, HP toners come with a sticker inside that you put to the box once you replace it. The box is picked up by UPS at no cost.
