What's wrong with using your home address for the SSID? Seems perfectly logical to me.
I have mine set that way AND I have it moderately secured. I have WEP enabled, which I know doesn't do much, but I also have MAC filtering. How common is MAC spoofing, and are there any exploits out there that can figure out some valid MACs from the over-the-air traffic?
I like using the address, not because I want neighors to waddle over and ask me about using my network or blather on about how they're a nerd too, but because if someone else picks it up they'll know right away "oh, that's not my own network, that's why I can't get this damn thing to work".
Hmmmm. What was the original subject of this thread? And you're proposing a Windows Media product? Putting aside that it's closed source, WMP does not have a good history when it comes to undesired actions.
I realize you're just a young-un' reacting with 2 seconds of thought, plus posting as an AC so you'll never see this, but you missed what I meant. Think about the following ideas and tell me that scientific truths mean something now:
With Bush's high profile success in getting a victory in the face of huge failures - by firmly insisting they were successes, now everyone is trying it. Reality doesn't matter, only how you can spin the perception matters.
Actually, I think the parent comment has been unfairly modded down into oblivion. At the very least it's interesting.
We do in fact have a new reality in work here, where scientific facts, objective truths, and reasonable conclusions from those do not seem to matter anymore.
So when Boeing and the DOD spin the launch as a complete success, with absolutely no mention of facts that indicate that there were some problems seen in the launch's first stage, I do see a parallel with the Bush Cabinet and the ignoring and elimination of dissenting voices.
Before modding ME down into oblivion, do this test that I always find useful: pick any current text description of a political situation and swap the words "Republicans" and "Democrats". Now how do you feel about the core issue? There's your objective truth.
You're all wrong. DD-MMM-YYYY (e.g. 29-Nov-2004) works best for human-to-human communications because it is unambiguous across cultural lines. It doesn't alpha sort properly, and in those computer cases I do use the ISO format, but otherwise you really MUST use the three-letter format. I think it's a happy medium.
And cross your handwritten sevens:)
Note: the SCP info that I linked to is not simply about extending the window size, it's a whole new data protocol designed to deal with the extremely high latency of deep space communications. The RFC you linked to talks about TCP extensions, including window scaling. That has little to do with SCP. Thanks though:)
a little math...
344 million km / (0.3 million km/sec) = 1147 seconds travel time
1147 seconds * 30 megabits/sec peak rate = 4.3 Gigabytes in transit at any instant.
Eeeeyup, that's called the bandwidth delay product and shows how much could be in the pipeline at any given time. This is what the TCP "window" value is for, and since most TCP implementations max out with a TCP window size around 64 kB, this means that TCP is very poor for space communications. Even TCP links over geosynchronous satellites (in 'stationary' earth orbits) have trouble when the bandwidth is high. And certainly in a deep-space application TCP is silly, due to the BWP and of course the TCP handshaking delay.
You had a comment recently that got modded up to +5 so I happened to see it. I happened to notice the low UID. Then I happened to notice the obfuscated email address, and idly I typed into google (the right way) for no particular reason. Stumbled across your resume...
Let me interject: I have no idea why I was wandering down this path. I am not stalking you.
Anyway, saw your resume and there it was: Adams Road, Martinsville, NJ. I grew up in Martinsville. Hmmm, Adams Road sure sounds familiar. I look it up and...
Dude, you're less than a mile from the house I grew up in. 2221 Brookside Drive. I lived there from ages 5 to 18, climbed those trees, played ball in that back yard, learned to bike on that street (and struggled up Stangle, and hauled ass down Vosseler), painted that garage, played in that brook, built the bestest rope swing ever in those woods, went to those schools (including BRHS East, which doesn't exist anymore apparently) and moved to Atlanta to college and never looked back.
Anyway, very freaky. Half of that town was farmland when I lived there.
Aaargh, I'm going to blow modding a thread to respond to this post...
Many people are confusing two separate issues here: visual imaging and radar topography. On this one pass, and on each of the other passes, Cassini will get A) visual image data on large parts of Titan's surface and B) radar topography on a SMALL PART. The radar sequence is very short -- they just get a little strip of radar data at closest approach and then that's it for that pass.
OVER MONTHS AND YEARS, they will gather enough to put it together and form a complete body of INTEGRATED visual and topographic data, and then we'll get the cool flyover renderings that make us all wet our pants.
But for now they have lots of visual data, which they CAN NOT use for determining topographic details due to the lack of shadowing, and a tiny bit of radar which they CAN.
You've got a CS degree, huh? Are you sure you're not just another 18 year old or maybe a DeVry grad? You're acting like one. Next time post as an AC so you don't make such a fool of yourself.
4. People talk about fuel cell cars constantly, but here's the thing; a fuel cell car will have to be a highly streamlined, possibly drive-by-wire, light-body device with electronic drive components and regenerative brakes; you get there by developing hybrids, not by skipping them.
The question is, do we want to "get there"? To fuel cells?
If you do the math on the energy equations, including the delivery system and most importantly the hydrogen production, you find that fuel cells are NOT EFFICIENT. You have to take into consideration the entire energy process, not just the last mile.
Of course, there certainly is a lot of political power behind a hydrogen based energy economy, because it would use the same old production and delivery systems that many, many people are make a lot of money off of right now.
Contrast it with energy economies that are decentralized, like home or neighborhood generation. This capability is getting closer every day. For example, every cost/efficiency improvement in solar has simply been matched on the market by fossil fuels by dropping their price, but at some point fossil fuels can't stay that low (witness the oil market right now, hmmm) and yet solar and other renewable technologies keep getting better and better.
Now, the big advantage that fossil fuels and hydrogen do have is that they are incredibly dense energy storage mediums. Nothing comes close, certainly not batteries; think about the wallop that 10 pounds of gasoline can give a car, versus 10 pounds of charged battery. So what you might find hydrogen useful for is basically as a battery -- you expend electricity at the hydrogen generation plant to create the hydrogen, and then create electricity in the car (or home, or business) via the fuel cell. You just need to transport the hydrogen around, which is a lot different than moving oil around, so good luck with that.
So, hybrids may be a means to a fuel cell end, but the end may not be feasible or even desirable.
a fantastic movie

Wow, interesting that this movie is getting Slashdot attention. When I saw this at the Atlanta Film Festival two months ago I immediately told everyone I knew about it. I've been using IMDB for a decade, but I created an IMDB account for the first time that day just so I could post the following user comment.
You remember the first time you saw The Matrix (please, not the awful sequels) and you could barely keep up with what was going on, trying to piece together the pieces of what you were being told into a coherent story?
This movie was exactly like that. The first half or so is fairly linear (despite the frenzied Altman-esque style of everyone talking on top of each other), but then it gets WEIRD and it just absolutely blew me away. This film won a major Sundance award, and normally that means I won't like it (especially the normally pandering audience award winners) but this movie, and first-time filmmaker Shane Carruth, deserves absolutely everything it gets. I am just blown away.
Did you like Pi? If so, go see this one.
By the way, the attention to detail in the beginning is great. Often in thrillers with technical content, if you have a technical education you have consciously ignore all the stupid movie crud that they pull to make it into a good story. But this movie pulls off an incredibly believable technical story, with only a few distracting gaffs. That is, the tech jargon is good enough that you don't get distracted and can focus on the story line.
Final comment: Yes, it is very hard to follow the story line in this movie.
Obviously I'm not going to spoil it, but I think the following fact will help when the movie gets kind of hairy towards the end: Aaron is the dark-haired guy, Abe is the blond-haired guy.
This movie now has distribution and you should keep an eye out for it in the fall.
