While I have cable myself, I do know plenty of people who are still pre sp2 simply because they are stuck with a modem. I help out where I can, but they often mistake that kindly little update for an eternity of 'free computer support'
20 odd megabytes is trivial in terms of storage capacity, but via a modem, it will be noticed.
Problem I've seen with some of the clusters around here (computers, not people) is the network load, some applications scale pretty well - brute force resolution of keys - others do really crap - TDMA demods through software...
If the appliation needs to be chatty about what it does, or throw loads of data across the wire before it even gets going, the $500 per node is going to jump quite bit higher.
gkrellm for windows. http://www.redbog.com/products/gkrellm.aspx It also monitors fan, hard drive, and other temps, though you have to get an external program similar to lm_sensors - the name escapes me at the moment though.. I'm not running windows right now to check.
When working as sys-admin I clearly tell people 'Do NOT give ME your password, I don't need it to do my job' - Ten seconds later - Now log in for me, 12 seconds later, my password is 'fluffy'...
People are dumb until it's too late, not all, but enough to make the stereotype hold true anyway.
I don't intend to be trollish, but the parent above is correct. Windows is certainly tedious to use when compared with the old style unix setup.
People do not use windows on a daily basis by choice, they do it mostly because they don't know anything different exists, or are so fearful of change they stick with it just like they stick with the same old job they've hated for years.
Sloppy focus, keyboard shortcuts through virtual windows, that type of thing - I know these can be obtained for windows, but the real problem is that they are not user selectable options available through the menu or config files on a default windows install. Maybe some are buiried in the registry, but that sure is not logical to operate.
It has to look good first - seems to be the default requirement for anything these days - I use enlightenment with numerous transparent 'aterm' windows open on every screen. I can expertly say that it is a much faster desktop for me than windows will be for the next several years, at least.
If it doesn't feel comfortable to use, then why not pick something that is - maybe windows does it for you, but don't denigrate an individual just because they oppose your world view.
How many free to air stations are there in London these days? From what I hear there are not that many? Don't you all have to pay a license fee for the TV as well, or did they do away with that silly idea...
I'm using http://www.trustix.org/ TLS for a few different things, seems as stable as anything else around on cheap hardware. I have no idea about its 'goodness' value, but for me it is good. To my knowledge it has not been compromised.
I've done a lot of RADAR work in the Navy, both at sea and land based, some of the equipment used can measure nano-second durations between pulses of radio energy, the equipment is definitely not off the shelf stuff - though I was led to believe by those much more intelligent than I that it was about the best available short of an atomic clock - our grey metal boxes are based on rubidium or cesium timing. I may well be wrong on this though, I was stupid and believed anything back then. (Probably still do)
Lots of big name universities these days have atomic clocks right? I would mostly question the validity of identical laser pulses though - whatever is switching that on and off so quickly will introduce its own set of problems - same set of issues as those surrounding RADAR.
Any precision that fine needs to be explained in intricate detail, not glossed over with eloquent professor speak that still says very little to a moderately educated dumb arse like myself.
I'm not sure if I'm in the minority here, but I don't consider VoIP to be any more a 'service' than web pages originating on port 80. It's just traffic over the same old wire. Only place it has any more importance is the 'board meeting' or those managerial key phrases the boss likes to use in utter ignorance.
Yes, the interface between the net and the telephone service will cost money, but IP to IP voice is a 'value added' type service how? (I know the OP didn't say it exactly that way)
I'm inclined to think corporate entities like to 'play up' the significance of what is really very insignificant just to make a buck...
Solaris will be used by the military for many years to come, its uses are as broad as there are uses for any operating system in existance. Not just databases or webservers, in my tiny little world we use it mostly for processing radio signals. This also includes demodulation of 'digital' signals through software, as well as de-multiplexing, removing overhead, decryption, stripping through reed solomon, trellis, etc, etc, etc... 'Infinite possibilities' comes to mind most frequently.
My apologies sir, I responded to the wrong thread - my mistake entirely. It may well be redundant, but that's a matter for the mods to care about, not me.
It's not easily possible to hide from any good EW system. They use multiple frequencies, pulse modulation, frequency hopping, staggered pulses, and a hundred other techniques that provide some really fine grained resolution - right out to the MTUR.
You also find RADAR on HF, it's annoying if your day job is to actually listen to the static, sounds a bit like a high pitched fart, transmissions are normally short duration though - less than 30 seconds then the frequency is changed - don't hear it again for a couple of minutes/hours.
RADAR transmissions are most common at the 9GHz band - india band navigation (boating/shipping) - the bane of many EW's existance.
That said, the transmission can be on any part of the entire spectrum. You can find RADAR on most any frequency. Including light. It's all about duty cycle, dopplar, PRF etc... EW radars modulate the pulse so you get high target resolution and your transmitter pumps out much more effective power. millimetric band radar is mostly only useful in fire control systems - short range.
Scatter the microwave as much as required, place receiving antenna on all your platforms to pick up said scatter and send it back to the source. Source computes the result, tank is dead anyway.
You NEED to make the microwaves disappear through absorption, or reflect straight down into the ground.
To say that a stealth aircraft is invisible to RADAR is a tad misleading. There are numerous ways to exploit the nature of the technology - current stealth for the most part relies on surfaces that reflect much of the energy anywhere but directly back to the emitter.
A simple example. Radar 'transmitter' and 'receiving' system located at an offset from each other. A distance measuring a few hundred meters to a number of kilometers. Scatter from stealth aircraft is easily picked up. (I speak from experience here) RADAR absorbing material is not very sponge like, just drops the return by a couple of DB for typical RADAR/EW emitters (400MHz-6GHz ish), nothing huge. Stealth is not really as complicated as 'they' say.
Stealth can also be picked up by most primary RADAR emitters (Air traffic control for example), it's more likely to be 'filtered' off the PPI, but can still be seen if the operator desires. Think small flock of birds. The kind of crud that is marginal and usually ignored.
Until non-microwave-reflective material can be used to build the entire aircraft, it will only ever work against low-tech level targets. By non-reflective I mean 'not reflect anything between 0khz-100GHz'
I use portsentry, send the syslogging stuff to a remote machine, which I then display using root-tail in near-real time - root-tail is somewhat antiquated, but if you like eye-candy...
Portsentry has the added (dis)advantage in that it will automatically dump suspicious IP's in to your hosts.deny file - or with some tweaking I'm sure it could also do it via iptables.
Electric formula 1, it'd be faster and more exciting than the current set of demented rules for the petrol based series yes? Might be worth watching until some twit decides they are too fast, then puts a stopper on the entire developement process.
Recovery in cases like this that have mostly worked: Dual boot or use knoppix or some such, what I do when this happens is run strings over the drive with some creative use of grep / less / more / awk etc... The 'vanished' code usually turns up duplicated across the drive in several places and states of completion. You'll still need to tidy up, mostly re-add all your comments and spacings, but often this is better than a total rewrite.
Then again, sometimes the re-write ends up much better than the original version...
Something I don't really get about Americans on slashdot, when they refer to the News, they also comment about how either the viewer or the station is 'Left' or 'Right' - whatever that means.
It's just the news isn't it?, not politics?
I know the stories are affected by 'the boss', but I still don't get it, even Americans have CNN, which less like Fox, and a little vaguely like CNN international. If I find a story on one channel to be interesting, I'll flip over to another station and see their take on it. Isn't this what most people do these days?
You missed the point by a wide margin. I was not trolling, software will always be a few steps behind the advertisers, the only way to stay in front is to 'learn', rather than 'depend'
Stopping popups in firefox with a tiny amount of tweaking is insanely simple - there are numerous tutorials about it.
Your last: I do drive by and admonish them if they are placing either themselves, myself, or other motorists in danger with their actions. If I can assist by pushing the 'problem' off to a safer location, I will.
My attitude is not shitty, it is simply intolerant of people who fail to help themselves in the face of such overwhealming documentation.

At least thats how it works around here...

It's plastic, metal, an efficient set of blades, and a generator, how on earth could it cost 500 million.
Outback NT, SA, or WA - unused land as far as you can see, thousands of square kilometers of it. Hot as hell, very little cloud, even less rain.
Where do these people get off saying 500 million.
This is not complicated science, people have been theorising about this type of power generation for at least 10 years.
So, this atomic pear, will it cause cancer if you eat it?
