He didn't, he lived to 93 - the 0 at the end was approximately how many tenths of years - common translation problem...many of the ages from that time had a "tenths of year" on the end...
I'm not married to USB CF or SD would work - something semi-portable would be for the best - as I would like to see the OS and OS only on the flash memory - maybe a couple gigs of that space wwould be writable for config files...
Think boot/OS disk...I'm all for speed, its just that USB is everywhere.
Why would you need 4x16G for the OS - Vista doesn't even take up that much...I was thinking of starting with around 8G for Windows and uses a union FS to map Windows updates over the original files.
No user programs here - interface-wise I wouldn't care that much - USB is everywhere and slow, but drop in SD or compactflash and I'm ok. More of purchase an OS on flash drop it in and nothing can touch it - if I need to wipe no big deal just rebuild the config files and clean out user data, and no more friggin programs writing files into c:\windows...
Now only if they could start following the server side folks and place an internal USB connector inside and then MS and others could give us the OS on its own usb drive (read only) and we could use the hard drive for updates and programs we could enhance the security as well...
Perhaps you haven't configured your kernel or power settings fully even on my old Thinkpad 760 (Pentium 166) I got 50% more battery life out of Linux then Windows...
If you check your CPU freq via/proc/cpuinfo does it drop? Perhaps you are using the "performance" instead of the "Ondemand" CPU Freq governor...
It depends on location - this for the spaces between TV broadcasters - areas with lots of TV stations will have less than areas with few.
The frequency band for TV covers several frequency bands:
VHF: -Channels 2-6 --59-88Mhz (88Mhz is where FM radio begins) -Channels 7-13 --174Mhz to 216Mhz
UHF: --Channels 14 - 51 (52 and above are lost to the DTV transition) 470Mhz to 698Mhz
Each TV channel occupies 6Mhz of spectrum bandwidth (Digital or Analog) minus additional channels that broadcasts use between towers and from remote trucks to studio to transmit live - lets ASSUME they take an additional 3-5 channels for each station for off-site. Each "On Location" and studio to tower link would eat these up.
Remember that studios are not often near the broadcast towers (due to the towers needing to be at high elevations) so they often broadcast the signal to the tower and it is retransmitted on the true station for service.
Even with an average 9 TV stations per area this could easily equal 36 or so channels actually setup for use.
36*6=216Mhz taken just for TV use. That is most of the ~290Mhz that is available between VHF and UHF. WHitespace devices will most likely stay in the UHF potion which trims down the spectrum to allowing just around 12mhz for a moderately populated area.
In contrast Wifi has around 84Mhz available and many tech notes suggest only running 3 "channels" (1,6,11) so that the devices will not step on each other.
5.8Ghz has 125Mhz for use and there is 26Mhz of 900Mhz that may be used. Lower frequencies allows for greater range, but you give up data rates...
If you can't tell I'm not a fan - I'm not seeing the upside to these free "whitespaces".
I know the general feeling of/.'s are very pleased at these results. Just remember this the next time you are watching TV and the reporter's wireless microphone drops out, or you are at a concert and the singer goes silent.
How is a whitespace device supposed to hear a 50-100milliwatt transmitter from 1/2 miles away?
It could be transmitting a few watts and is desensing the wirelesss microphone's front end or overpowering the channel.
Sure the Pro Audio industry will need to make some changes to adapt, but users such as singers and corporate CEOs tend to get awful angry when their mic doesn't work...
I suppose Lectrosonics will get some additional business as they have a slick frequency hopping TX/RX pair that will help some - but there will still be some dropouts.
Like the crappy camera in the phone - my daughter' Crayola camera takes better pictures
Color screen - really what need to I have when the web browser doesn't support javascript or CSS [besides I can't read it without the backlight on, which sucks down more battery]
Music/games - yea a buch of java demos - that suck, if i want music - I need a standard headphone jack, and well storage...
Just give mne a grayscale daylight readable screen, bluetooth, and a contact list and I'll be all set.
Really. I still miss my Qualcomm QCP-2750 - sounded better than anything since - battery lasted a week, good UI and scroll wheel.
AND I LIKED THAT IT WAS MORE THAN A mm THICK! Can't cradle most of the new phones on your shoulder!!!!
Pick the largest and buy up as many usb or firewire interfaces and drop them in a tower case with a psu for the HD's (get bus powered usb/firewire interfaces) and have a decent sized external array...
or use the larger ones as customer throwaways - when the video needs to go to the customer and its really big - ship them a cheap usb/firewire enclosure with a disc in it loaded with their video - if it doesn't come back then you've got more to spare....
But if it works well in the test environment your could then transition into production - I would us this for other items than swap; most servers have plenty of ram, its those small seek happy applications that need alot of temp space (like AV and Spam checkers for mail servers, PHP temp space) items like these could be mapped there instead of tying up disk I/O for very small and transient files
A firearm for protection from four-legged ones?

Some of us think it wise to carry a firearm for proctection from two-legged predators as well, for those who think four-legged predators will not be a problem, perhaps you camp in your backyard more than the great outdoors!
Hrmmm, perhaps you shouldn't use port 25, as that is the MTA to MTA port, you should be using port 587, the Mail submission port, then you can avoid this nonexistant problem, It certainly isn't their fault if you use the wrong port....
I did a step worse...I was testing a backup and restore process, and wanted to delete all the files except the directory....including the hidden.files, I without thought typed rm -r.*, and after a minute or two I stopped it after I realized that it was taking wayyy to long. (this was on our primary DNS, RADIUS, and NFS server) needless to say I had to reinstall and recover from a backup....it was quite a mess...
as an owner of an F5, I find most Nikon's controls as logically laid out. A N75 would be a good choice for a beginner, or if you don't mind a manual camera, you can have an inexpensive pro-level camera and lenses for a great deal, look for the Nikon FE, or the FM used, like on KEH.com, a great source for high quality used cameras. and with a Nikon, when you upgrade from a manual-focus camera to an autofocus camera you have a good chance of being able to used the great lenses you already have!
Try STP instead of UTP ethernet cable, more expensive, but it will reduce the conductors' ability to be antennas/capacitors/inductors. Use normal ends (plastic), but tie the shield to ground inside the house or at the pole to drain off the built up charge from the electrical storm. The eight little wires in ethernet cable will collect and move enough electricity to easily take out most unprotected / consumer equipment
Actually, it is very helpful, this doesn't enable networks to have gateway address failover, it creates a virtual gateway address, so that all clients go through it, the two (or more!) routers that actually handle gateway traffic for the network are on other addresses, but the clients never see them, if one dies, you only loses connectivity over the link that router serves. Many (most?) business networks have only one router/gateway, if it goes down, they loses total connectivity even if they have redundent circuits or multiple providers via BGP or whatnot. This gives greater likelyhood of total up time, plus its allow for gateway router upgrades, patches, repairs, etc. with invisibility to network users. (Plus it lets guys like me get sleep at night, forget having to schedule router down time for Saturday morning at 2am so noone notices, now I can do it on tues at 11am!)
Hello? Why didn't he review the wonderful offerings from supermicro, I have one of their very nice 400W, and we use them exclusively at our shop, can't kill 'em. Weigh a ton and are fairly expensive ($150) but well worth it.
Ummm buddy the newest Linux is 2.4.0, you are probably referring to Redhat Linux 7.0, which as I recall is the redhat Distro's most recent release, you see Linux is just a kernel, all the other stuff is distro stuff, oh yeah and my personal fav is Slackware, I love the flexibilty, and intelligent setup options and lack of dumbed-down interfaces, I respect Debian too, thank you guys for giving us Distro's for the Linux old-timers.
Such a transmitter is usually called a flashlight, crt, desktop, etc. since everything is actually a wave, oh and just to mess with your mind a bit: your eyes are really just antennas to pick up light waves frequency signals.....ponder that....so no you don't see something you receive its signal.

I've heard 96khz/24bit, and it does sound amazingly better, while most of the world does not have audio equipment to really do it any justice, you most likely will still be able to hear the difference through your speakers, the clean audio signals, adnd the crispness of the sound make it sound closer to the real thing. Besides even your normal cd's will sound a bit better in the DVD player from the superior A/D converters, and the advancesments in this field in the last several years, don't be stuck on the idea that CD is as good as it gets, because it isn't, I believe CD's sound worse(you lose warmth and energy from the music by sampling it, increasing the sample rate will help this), remember technology advancements happen in more areas than computers, they also happen in other fields, and then get added to the computer realm.

Only 40-bit DES? ABit needs to find a better algo. Please, the NSA can decypt this faster than realtime...
they should be blocked anyway....135,137-139,445...then the yall go away...
