I don't know about a good change control system, but our standard practice when editing a document that's been issued (a valve list or a process calculation, say) is to give all the changed cells a coloured background.
Then when the next revision is being edited, all the colour is removed and the changes in that rev are coloured.
It's not all that robust as it depends on the user to do the shading. Also, calculated cells that also change are easily missed.
Also, we have a cover sheet (like those TPS reports...) that contains all the details like dates, reasons for change, who checked it, etc.
If it were down to me, we'd be using MS-Access for this stuff. I once developed a complete roll-back system in VBA for an MS-Access database that stored each change in a table together with the old value. The original or any intermediate state could be retrieved by parsing the table back into the database.
Same in engineering. You wouldn't believe the number of times I see Engineers using Excel to create things like drawing registers and equipment lists that belong in a database. It's one of my pet frustrations.
...Which is probably why Australia didn't bother until 1975, after the rest of the world had sorted out the standards for us. Then we adopted the much superior PAL system rather than NTSC.
I remember when we had our first colour TV installed, the technician advised us to set the colour control using the News broadcast as a baseline, since the foreign (read American) shows were too inconsistent.
We are transmitting, and have been for over 70 years.
Ever since the invention of radio transmissions, there has been an expanding bubble of random RF moving away from the Earth at the speed of light.

Actually most sewage plants have a digester in them (or several).
Most Sewage Treatment Plants that have anaerobic digesters (the kind that produce methane) simply flare the gas off, because the quantity of gas produced doesn't warrant the expense of setting up to re-use it.
Seafield Sewage Works in Edinburgh, Scotland does though. It was completed in 2000. If you fly into Edinburgh airport over the Firth of Forth, you can see a row of six large pink tanks near the docks. These are the digesters at Seafield. (The reasons why they are pink are complex and architectural, not functional).
Bondi STP in Sydney used to re-use methane for generating power the 1960s, but the the technology was primitive, and the sulphides in the gas made the engines expensive to maintain and they were abandoned.
Now in Australia, with green energy credits on offer, many water authorities are having another look at making use of their methane.
These are great if you live in a dry climate (Texas, Dubbo, Sahara Desert) but they aren't very good in a humid climate unless you put ice in them. That means that here in Sydney and in most coastal type areas they aren't usually very effective.
Random breath testing was the answer here in Australia, we still have a problem with ppl driving dui, but nowhere near as much.
There is always the risk of an RBT waiting around the next corner.
I have been tested about three times in twenty years, and it never takes more than a few seconds. Much better than some stupid device that you have to get past every time you drive your car, but then I guess that's another thing that having an 18th century Constitution forces on you.
Yes, but if you own the code, you can publish under as many different licences as you like, whether or not they are compatible. cf MySQL, QT, ghostscript.
Leaving aside the quality or otherwise of Disney movies, if I just want to watch a movie once and not pay A$35 for the privelege, currently I will rent it.
If the movie people want to provide a mechanism by which I can do that without going to the video store, I don't have a problem with that.
What I do have a problem with is having to have a specific environment in which to watch that movie, and no possibility of my chosen device ( if it is not a microsoft one) being able to play it. It's the lack of standardisation in the format that's the problem, not the fact that it's encrypted.
If the chosen DRM method was usable on a TIVO or a Foxtel set-top box or a Linux/BSD/Mac-OS PC rather only an X-Box or a MS-Windows device, then there would be no problem, but we all know how Microsoft does these things don't we?
Is probably to prevent things like X-Box Linux and other unauthorised code from working on the new systems, thus preserving the royalty stream from the game developers.
New Digital Restrictions Munging will no doubt be in force to make sure the only thing you can put in your X-Box 2 is X-Box 2 games authorised by Microsoft.
Text book gouging of this sort has been going on for years. One of my engineering lecturers worked around it by giving the assignment references from the current and previous editions. The only thing that had changed between them was that the assignments had been switched around.
Your example reminds me of a shoe store in Shanghai, where the salesman insisted that I should buy the black shoes that were all he had to offer, even though I already had black shoes, and was there to buy brown ones.

In fact each individual's chances of actually making it are slim. it makes you wonder why they bother.
THey should give up if they are not:
1. Virgins
2. Male
3. Jewish
4. Martyred for the cause of Christianity
Becuase according to revelation, those are the prerequisites.
Ssh! better not tell the Americans! THey might decide to go there to look for Weapons of Mass Distraction

Unless you live in FLorida, and your name is Chad... Wasn't that how it went?

I have this as an LP still. Maybe it's time to go and find that new needle for my turntable.
On the other hand if we create an inverse tachyon beam and modulate it with their shield phasing, we may be able to...
I'll shutup now
Obviously doesn't apply in Gauntanamo bay. Something about goose and gander here...

Actually, there's nothing stopping anyone from incorporating BSD licenced code into a GPL project any more than it stops Microsoft or Adobe.
It can't be done the other way though. Neither proprietary nor GPL code can be put under a BSD licence.
Searchable goblins perhaps?

actually this appears to have been corrected. Now it just says "data"
