As far as I can tell, the whole poll is off by an order of magnitude :).

I'd have to have some kind of plugin to tell me how many tabs I have open.

I had a similar issue. I saved all tabs as a bookmarks folder, then opened the folder and saw the number of items.

Comment Re:Spectrum? (Score 5, Informative) 128

I do not know what is the limit of the "wireless spectrum" if there is any. Before this limit is reached, I guess just updating all hardware gears that transmit/route more efficiently is all that is needed.

The limit is given precisely by Shannon's Law, which gives a mathematical limit on the amount of data that can be sent over a given amount of bandwidth. Spectral Efficiency is the amount of bandwidth available in a given wireless spectrum.

How would you use broadcast or multicast to distribute an OS? Call me ignorant, but how would you do that in practice?

I used to work in a computer lab at the university I went to. We used Ghost to do exactly that. All the computers in the lab (a few hundred PCs) were booted up off a special floppy (or later, cd) that started up Ghost in listen mode. Then, the central server used multicast to send the OS image to all the clients at once. It took less than an hour, and that was with 100Mb/s Ethernet.

Here's a question:
To know which bits have changed, doesn't it need to compare the two files. How does this result in bandwidth savings?

No, because it only sends a hash of the data. The other side computes a hash of it's data, and if the hashes match, the transfer is complete. If The hashes don't match, there is a rolling hash that can verify a partial match, and send only the changed data. There's more info here

Comment Re:Can laser printing create nano-size circuits ? (Score 1) 83

"For example, the latest Intel's microchip, the Ivy Bridge (and soon the Haswell) have circuit-sizes as small as 22nm"

I'll bet on the traces being even smaller than that. You must mean transistor size.

It means feature size. A feature can be part of a transistor, or a circuit trace, or a bunch of other things.

Comment Re:Arcfour (Score 1) 90

Oh, wait, it's the arcfour key scheduling thing again.

This is an old arcfour weakness, not news. Everybody knows about it (and how to avoid it). The SSL people just never bothered to do it.

According to the slides, this attack works by exploiting a bias in the output of RC4, not the key schedule at all...

The amusing thing here is that the Naginata is probably more immediately recognized by this audience as an ashandarei.

Yep, I came here to see this. I didn't know about the Naginata however :-) For those not in the know, an ashandarei is the weapon of Matrim ("Mat") Cauthon in the Wheel of Time series.

My favorite terrible progress bar was Internet Explorer, back in its early days of essentially being a renamed version of NCSA Mosaic. When attempting to load a site that wasn't available, the progress bar would slowly creep towards complete, despite the server being completely unresponsive. Then after a long while the browser would give up and stop the progress bar. Why on earth would the progress bar move if the server is completely unresponsive? Who programmed this? I would hope that they, like the inventor of Clippy, suffered a terrible death by fire.

Early versions of Netscape had an issue where if a download was getting slow, the speed would creep down and down, until it hit a divide by zero error and crashed the browser.
