I agree that the current security of Wireless networks leaves much to be desired. But that doesn't mean that we shouldn't at least use the little bit that we have.
I hope that they are able to improve on the security. But remember, that nothing can keep out a determined hacker. You can have the best locks, the best security system, and the meanest guard dogs, but it is still possible for someone to rob your house. They'll just have more incentive to go find an easier target.
You're claim that their security tips are useless is silly.
> use wep (airsnort)
Using WEP is the same as remembering to lock the doors of your hose. People can still pick the locks, but they have to be determined to get in.
> obscure your ssid (set client ssid to ANY)
This should be combined with the suggestion below to turn of SSID broadcasts.
> change default passwords on APs (duh)
Just because its obvious to you, doesn't mean it isn't worth mentioning. People are stupid and need to be reminded of the obvious.
> disable broadcast ssid, but you can't (haha)
Funny, on all of the Access Points I've dealt with, there was either an option called Disable Broadcast SSID, or Closed Network. Checking these meant that you had to know the SSID in order to attach to the network.
> upgrade firmware (what's that gonna do)
Why should we apply patches to Apache or IIS? What's it gonna do?
> enable MAC filtering (Lucent WaveLAN cards have a tool to set their MAC address)
Yes, but there are 2^48 MAC addresses. Guess which ones are allowed to attach to my network.
> Turn off your access points when you are not using them (how mann people are going to do that)
I agree that this is unlikely to happen. But that doesn't mean that it isn't a legitimate way to keep people from using it.
Wave point placement and antenna selection (attacker can use a 12dBi yagi and point it straight at your house)
This point I don't know enough about. It is probably the least useful of any of the suggestions. Especially since most people tend to use the antennas that come with their Access Points
Unfortunately, in the US, 100Mbs at college usually costs between $4000 and $30,000 per year. Plus books, room and board, and the cost of pizza every night.
Having read through all of the hardware portion of the article, I must say that this sounds like it was a first draft that was rushed to print, so to speak. The grammar in places is atrocious. There were times in the article when I had no clue what the author was trying to say.
I guess it's time for them to hire a new editor. They need someone to proof-read these things before they post them. Not only for grammar and spelling, but also for fact checking.
Nah, Apple has kept the resolution limited to the standard 1024x768.
But look on the bright side, now you won't have trouble seeing the pixels. After all, they'll be about 3 inches sqaure. No more trying to determine what color that pixel is.
USB Hard drives don't seem the best way to go if you want to do video editing. I tried plugging my Firewire drive into the iLink port on my PS2, but got nothing for the trouble.
Anyone else had any success with such a configuration?
If a CD won't play in some CD Players, then doesn't it violate the Red Book standard for CD Audio? If so, then how are they allowed to slap the Compact Disc Digital Audio logo on to them?
Sounds like ground for a class action lawsuit once they start to arrive.
Yes, there is something called USB 2.0. And there are very few computers currently that support it. Most computers out there have USB 1.x which only goes to 12Mb/s. Firewire is 400Mb/s and is a widely available standard. Apple ships all the computers with Firewire, and add-in cards for PCs can be had for less than $50.
So, in terms of viability, I think Firewire wins out over USB 2.0 at the moment. Afterall, Firewire has a large headstart and is rapidly becoming the standard for high speed device interconnects.
A USB Hard Drive is *not* the fastest way to back up your data. Firewire drives are almost as cheap and are *much* faster than USB.
I had a co-worker who bought a USB drive, then promptly returned it and bought a Firewire one because the USB was way to slow. And having used Firewire drives, I can tell you that they are plenty fast enough for most backup jobs you will ever do.
Can someone explain to me why this is posted as under YRO? The group publishing this list is in no way tryingt oundermine your rights. They are trying to provide parents with a guide to what there is out there that they may or may not want there children to have. This is not a crime and in no way affects the average slashdotter. Unless the average slashdotter is a high school student living at home.
You're forgetting the fact that we are looking for fast access time, not fast seek time. Seek time measures how long it takes the drives to position the heads over the track containing the data. The other part of access time is the drive rotational latency. This is the part that higher RPM drives reduce.
If the drive spins at 5400 RPMs, it's rotational latency is about 11.1 ms. A 7200 RPM drive has a latency of about 8.33 ms. Thus, in a worst case senario, the 7200 RPM drive will get to the data almost 3 ms, or 35%, faster than the 5400 RPM drive.
So, while the seek times are the same, probably because they use the same mechanisms, the rotational latency plays a big part in calculating access times.
802.11 uses the 2.4GHz spectrum. I don't think you'll find anything inexpensive that would run it at the 3.7 to 4.2GHz range you mentioned. And the you also have to factor in the cost of that equipment for both the central location and all outlying locations.
At a place I used to work, we were developing a new operating environment, and the lead designer had incorporated a time based file system into the UI. It would list all the files in chronological by their creation times.
The theory was that you might not remember what you called a file (like my wife), but you usually could remember when you created it (Tuesday right after I had my morning coffee, but before the copier broke).
Unfortunately, financial difficulties resulted in us abandoning the project.
Since I work(ed) for a company with 11 people total, 6 of which were software engineers, we knew each other fairly well. The engineers would get together occasionally. And we usually let each other know how our lives were going. Especially when they started laying people off.
Sounds like your priorities are a little skewed. You may not feel that you need to pay attention in certain classes, but the skills learned will come in handy. Just wait till you get into the real world and you have to sit through long boring meetings. Knowing how to pay attention will really come in handy. Especially when someone unexpectadely asks you a question!
I have heard a number of good things about Listar.
From their website: Take a look at Listar's feature list, and see the advantages it has over other similar Listserver packages. (anti-spam hooks, ability to strip down MIME messages and remove their attachments, virtual hosts, just to name a few).
FireWire Powered drives cost more, not less
on
Firewire and Linux?
·
· Score: 1
Firewire Powered drives cost a good deal more than regular AC powered ones. The cost of the electronics to pull the power from the FW Bus drives the price up.
I've seen Bus powered drives that cost as much $120 more then their AC powered counterparts.

So, would that be called the Great Firewall of China?

Up to 768K down, 128K up.

Acutally 802.11g runs 54Mbs at 2.4Ghz.
802.11a runs 54Mbs at 5.4GHz.

From other posts here on Slashdot, it has been reported that in order to play DVDs on the XBox, you have to buy their DVD Remote for another $30+.
Gotta love MS and their "DVD support".

Ah well...
The ultimate laptop. Wireless, Widescreen, gigabit ethernet port. Runs Mac OS X (and Linux).
