Recurse through the libraries used by the application. You don't have to know if a particular function call is used second or third hand because if the application or library calls a patched library at all then the service has to be restarted.
Not only is locating affected binaries trivial scripting, finding currently running and affected services is even more trivial. Restarting said affected services is entirely automatable on a site wide scale.
This is bread and butter systems administration. I'm sorry but I sincerely hope you aren't representing yourself as a systems administrator to your employer.
Don't know anything about the patriot act. I do know that the UK government can right now define you as a terrorist and lock you away without any legal representation or trial, indefinitely. They've done it already, all it takes is the signature of the home secretary.
What you want is an IBM "Enterprise" tape drive. 40MB/s native streaming speed and 300Gb native capacity. The average drive compression ratio is 3:1 so you can get 120Mb/s and 900Gb on a cartridge.
I personally believe that infrastructures of any kind don't make good candidates for ownership by commercial organisations. The requirements do not match, an infrastructure is depended upon by society, it's required so that people can go about their business and not have to worry if it's going to work at all or if it'll work the same way tomorrow as it did today. More than anything else, an infrastructure must be stable to allow others to build services on it.
Examples of commercially owned infrastructures which can cause problems:
Operating systems: Windows, what would you like us to change tomorrow?
Power: California and New York, can the deregulated UK power grid remain stable?
You don't do affordable 2,400 sqft housing. You take the bottom out of the market. The price for 2,400sqft apartments starts dropping as a result. Meet the demand. It's no good just controlling prices legally if the demand isn't being satisfied, the demand has to be met and preferably exceeded. The market has to be liquified to allow movement.
Shitty cities are just bad planning. They don't have to be concrete jungles. Europe has many examples of cities which work very well indeed, I'm sure America does too. Unfortunately it can take decades to redesign the bad bits.
It doesn't take decades to begin solving the traffic problem but it does take massive political will. And no it really isn't simple or idealistic, just mentioning "new high density housing development" sets off all sorts of fireworks. It sounds simple when you say "traffic congestion is a symptom of the housing shortage". Actually fixing it is decidedly non trivial.
You have kind of made half my point but from a different perspective. You have (or you think you have) a better quality of life by living in the burbs, i.e. it's shit to live in the city. So yeah the environment matters but cities don't have to be shit environments to live in.
You also haven't mentioned how much it would cost to buy an apartment in the city, within walking distance to your place of employment of a similar size to your house. Rent is burned money, a mortgage is an investment so you're investing twice in your mortgage what you were burning in rent. Travel is also burned money btw. The rented sector is one of the vested interests I mentioned.
Try to use a technological system to bypass the symptom while ignoring the root of the problem.
Traffic congestion (during rush hour) is caused by people commuting from the suburbs to the city to get to work. But why do people commute? Why not just live in the city near to where you work? Well, the housing is shite and bloody bloody expensive for what you get, it's cheaper and better to live in the burbs and then spend 2 years of your life sitting in a steel cage in traffic.
So traffic congestion is a symptom of a housing problem. The solution? Good quality low cost housing in areas with bad congestion. It'll never happen though, it's a politically unacceptable solution, there are too many powerful interests making money from the high demand, low supply, expensive accomodation in towns and cities.
At the moment the IT sector in India is going through massive wage inflation, it's worthwhile outsourcing on a cost basis at the moment but in 3-5 years it's not going to be nearly as cut and dried.
The wage inflation strengthens the local economy, pushes up local demand, pushes up costs and strenghtens the currency, this will dramatically reduce the cost differential with western countries.
The Indian offshoring companies like Infosys are already desperately trying to move upmarket into business consultancy. The same will be true in China as well.
Course, the market's now much larger, more competitive, developers are never going to earn what they have till now and America is going to have to start getting used to treating developing countries like China and India on a more equal basis.
If you're thinking of this computer or that computer then you won't make an effective systems administrator. You have to see the network of all of the computers as a single whole and treat them as such.
Once you've got the mindset change sorted, 10, 100, 1000 systems it makes no difference, it's just as simple to manage. You aren't managing individual computers, you're managing an infrastructure.
Course, you actually have to be competent as well... Obviously.
I'm a sysadmin in a very large corporation and when we run out of space, I tell management. In fact, I tell them in advance, regularly, that's what capacity planning is all about.
If they decide not to do anything, like let me buy more disk or a bigger file server, I leave the space full and suggest files which might be trimmed or people who are using more space than might be reasonable.
It's their problem, they are the ones with the purse strings and it's their production which is being halted by their stupidity.
X11 on a dual CPU box kicks the arse of a single CPU box, even when the X server itself is single threaded. Why? Client/server architecture, on a single CPU box it context thrashes between local client applications and the X server.
So if you run Linux with X11, go for a dual. You *need* it.
See, now I've given you an excuse go persuade your boss to buy one. You can thank me later.
They write nice and smoothly with a consistent application of ink and no splodges. Lovely, I haven't found anything which writes better, including expensive non disposable pens.

Say you don't agree with what they have to say. You define them as a terrorist and lock them up indefinitely.
Recent anti terrorist legislation has made this entirely plausible in the UK.

Not cheap though.
and more efficient than photovoltaics. Not quite yet on a par with conventional power on a cost basis yet but getting very very close.
It's difficult to see how it might power a vehicle though, stirling engine?

Good article. I know several places where they committed all of the sins.

Ah I see you are speaking from years of ignorance.
In the UK, terrorism legislation is very broadly defined and has already been applied to peaceful protestors.

Maybe if you use a big square bag to hold the buoyant gas it might be inefficient, but you'll notice that most airships are not big square bags.

In fact airships are significantly more fuel efficient than aeroplanes for holding position.
The Japanese are testing them *right* now.

The atmosphere is an ocean, you can float on it effortlessly. Why spend so much time trying to expend energy to stay up?

As well as having a full Linux distribution for Intel based kit. Buhbye CDE.
Architected correctly, the TCO for this Solaris or Linux will be low. Architected incorrectly you might as well not bother.
It's irrelevant to everyone but coders.
Bhwhahaaha. You'll have that stuck in your head all day now...
Of course, intelligence is your immune system and "The Grid" is the latest fashion.

And put them into a working drive chassis.
I mean, really. If they've filled the disks then they need more space, why on earth are you fucking about in this bizarre way?
Seriously.
