It's 27MHz. It'll penetrate anything. The only reason why distance is severely limited by default is that the antennas are crap.
The theory I saw for that is that it needs a sizable moon.
The tidal forces would get it's liquid core pumping, and help strip the atmosphere.
Hmm, so a planet needs a good-sized moon to be habitable (at least for us). Venus has been hit hard at some point, enough to make it practically stop spinning, and Earth has apparently been hit hard too, enough to create the moon. Odd how two planets both got hit, with one affected a lot but no ejecta, and the other apparently unaffected except for suddenly having a moon. What if the moon came from Venus instead of Earth?
I read your message, but your opening statement of "Well you are obviously clueless" made me think less of you immediately. You might want to work on your communication skills or try to be nicer to people that you perceive to be your enemies.
You are obviously clueless.
I hope you're not one of those people that flies off the handle in indignation before thinking.
I hope you're not one of those people who like to molest children. And did you stop beating your wife? (Ok the last one doesn't work so well on Slashdot).
Yeah, but it is a pain to make HVDC or step it down to lower levels for distribution. After all there is no such thing as a DC transformer (which of course wouldn't make sense).
High power electronics make it easy to "transform" DC. It's a solved problem.
And note that most industrial electric motors are 3 phase AC motors.
The are being phased out (no pun intended). They are inefficient and being replaced with variable frequency AC motors. It is even easier to get variable frequency AC from DC than it is to get it from 50 or 60 Hz AC.
It's also really stupid in this day and age that you need to be root to bind to <1024. There's just NO need for that any more that I can see.
You trust all your software to not try to bind to port 25 and steal your mail? Or to port 80 and deface your web site? If you trust all your software, why not just run everything as root in the first place?
he specifically said only bytes, so why do you start trying to apply it to bytes per second which is a totally different unit?
Ah, so when I have a 20GB hard drive with a 20MB/s write speed, overwriting the disk doesn't take me 1000 seconds OR 1024 seconds, but actually 1074 seconds? I admit I hadn't foreseen that particular insanity.
Spec'ing FLASH (and anything else directly addressed by a CPU for that matter) in base 10 makes no sense. The hardware simply does not work that way, and its incredibly inefficient to do it. Representing the number 10 in base 10 in a computer would require 8 bits, it only requires 4 if you do it in base 2. Assuming we would be using BCD to do this base 10 representation would mean we have to use 4 bits for every digit in the number. Thats a very huge waste! I suppose someone could build an analog computer with 9v (or equivalently scaled) logic and do it, but why?
You are awfully confused. The size of the medium has nothing to do with the way we represent numbers on that particular medium. To the computer it's just a bitstring with a particular length. There is no constraint that the length should be a power of two. Each chip tends to be a power of two long, but the computer doesn't see the individual chip -- there is remapping and wear-levelling in between. NOR flash tends to be directly addressed by the computer, just like RAM would be, but NOR flash capacity is basically zero anyway, so who cares.
Why do you say Flash chips are in powers of 10? They have address lines just like RAM (and ROM), so at their core, it is based on powers of 2.
So what if they're based on powers of 2? They use variable amounts of space for sectors for reallocation and various other things. Fun will be had once we get to store say 6 levels per cell -- then they'll be based on powers of a non-integer number.
The powers of 2 apply to bytes and only bytes, nothing else
They apply to bytes, when you happen to talk about RAM. Anything else, even flash, is in powers of 10. Sometimes, but rarely, they apply to bits as well -- 2Mbps E1 is 2048kbps. ADSL can go either way. In short, "consistent" is certainly not a good description of this mess.
It makes about as much sense if the SI had standardized base-10 units of time other than the second.
No, the comparison is if everyone decided to call weeks dekadays, but keep their length as 7 days. It's simply wrong. If you want to use the SI units, use the SI definition. Otherwise come up with your own terms.
Thanks for the support, but don't worry too much about the moderation. My experience is that even my most inane comments get moderated positively, so it's somewhat refreshing to be modded down. Anyway, your explanation of the problem is much better than my attempt at humor.
"Of those, almost a sixth actually used P2P technologies from their work PCs."
Ooohh scary. I guess I'll be testing Fedora 8 later than expected, since using bittorrent for fetching it is now completely out of the question. Except that the company policy luckily does not forbid using "P2P technologies" where I work.
You can't drop below 1ms because of the latency implied by the network equipments (just to go through their hardware takes a few milliseconds - not to mention stateful equipment such as firewalls or load balancers, etc.)
Here's a nickel, kid, go buy yourself a real firewall.
...in Windows. In Linux, I have never had problems. My colleagues who use Windows swear at them all the time. Extra fun is had when they're out in the server room and suddenly realize they need a driver for their USB serial.
So it might be something in the card itself causing the slowdown.
The PCI bus and its derivatives (AGP, PCI-X, PCI-Express) is basically send-only. If you try to fetch across it, things can't burst properly, and access is very slow. Most PCI and AGP graphics cards don't have proper DMA engines for sending, so the CPU has to fetch. Many PCI-Express graphics cards can be told to do DMA.
If you have a DVB-C-capable infrastructure, it's rather stupid to then put your cable channels into IP. It makes more sense for video on demand though.
Multicast requires routers/switches to keep track of who subscribes to which stream. It isn't realistic to do on the Internet backbone. It's good and very useful for company-wide stuff, and even for ISP-wide stuff though.
I was wondering if you had any advice towards getting a decent wireless SIP phone
Wait a year. Or go with whatever the US equivalent of a DECT base with SIP is, like the Siemens Gigaset 450. Don't be fooled into getting a WiFi phone -- the hardware is crap in most cases, and in the rest of the cases the software is crap.
Whether paying for a war of aggression far far away, or for healthcare for people too lazy to take care of their own bodies, or for drug law enforcement, or bailing out failing obsolete industries... I don't just "not want to", I find it outright offensive that the bulk of my tax dollars go to causes that I absolutely oppose on both moral and practical grounds.
Luckily you have to pay anyway, no matter how offensive you find it. Why should we tolerate your offensive egoism?
I'll disagree with you on this point, and it was one that annoyed me about my Amiga 2000 back in the day. Text scrolling was at the CLI was S-L-O-W compared to my Tandy 1000 (8088), even with FastFonts loaded.
That was a problem with the terminal though. CED could fill the screen at what seemed to me to be 60Hz.
No, on the same hardware a GUI will be slower than text based.
If the hardware happens to support text mode. The Amiga could do a perfectly usable GUI with a 7MHz M68k, and the comparable Apples weren't that much slower. That doesn't mean I want to go back to those, or to text mode.
"How do we pipe hot stream around to people? How does that infrastructure get built?"
The same way other infrastructure gets built. What's the problem?
Anyway, if you mean steam instead of stream, then don't. Hot water is good enough for almost all purposes, and if you have steam available, it's better to turn it into electricity and hot water.

It's remarkable how much that sounds like "conspiracy", isn't it? Also bears a striking resemblance to "price-fixing".
It has the advantage over price-fixing that it is perfectly legal.
