Seriously, avionics is what Ada was invented for. This loony love of C++ at corporate levels is going to get people killed. Well, FAA certification requires provably correct code, but there are other embedded scenarios that could be dangerous.
However, it sounds like that business was ready to fail.
I am rapidly coming to the conclusion that it's very easy for a business (or individual) to generate more data than they can afford to keep. I don't know your position within the company, but it sounds like the boss ran things on the edge without sufficient insurance or maintenance or IT budget and finally got burned. If he was doing that to be the "price leader" then it turns out that your service was sold below cost. If it was just to increase margins...
(Oh wait. You said that this was a textile business. Then blame unions and minimum wage laws.)
Data protection and business assurance are damned expensive. Disk drives, RAID (soft or hard) and computers are very cheap these days. Real data protection is not as you have sadly learned. Believe me here. I work for a tape drive manufacturer and our internal IT is a shambles because the software and procedures to provide true reliability seem too expensive. I have steadfastly refused sysadmin responsibility due to this.
You asked for a good tape drive without stating a budget. I will say that LTO-2 systems should be within your price range. If your boss was serious about having a 2TB database, then you need protection systems for 2TB of data. You certainly didn't generate 2TB a day! so do incremental backups off a master copy taken infrequently.
Re-reading your question (I know, that's against the spirit) I see that you want to do a "short film." Think right now about your target media because as the parent post says, you can never add information to a image. Standard definition video will look like crap on a movie screen, but will save you boatloads if all you want is a TV.
Traditionally short subjects have been shot on Super-16 film cameras. Folks on a lower-budget or only targeting video might choose to use standard definition video cameras. These days you can also choose HD video at 24p which ought to get you results closer to film and the ability to project on a big screen without too much embarrassment (not due to your crappy content.)
To re-phase your question, what resolution media do I want?
Some SD video cameras are better than others (obvious), but they CAN NOT do better than 720x480@60i on output because that is the quantization for ITU-R.601. HD cameras can give you up to 1920x1080@24p. Film will look marginally better, but is challenging.
To get good results with SD video you need good equipment and lights. The tape format you use affects the end product just like the camera and lens. Many TV news mobile units have switched to DV (mini-DV) at the very lowest end or DVCAM. DigiBeta will give even better results at a significant price increase. The nominal resolution does not change, but quantization and compression do.
This is doubly true with HD equipment. You will want to rent the HD camera, especially if this is an experiment. Nobody has an uncompressed HD recorder, so just go with HDCAM and be done with it. You probably want to rent the VTRs too. There are quite a variety of HD cameras out there. Most of them a optimized for video, but a few like the Thomson Viper Filmstream are intended for film replacement. The difference is in color balance, gamma, and other things that have different conventions between film and video production.
I really don't know anything about film cameras, but I am certain that you'd be renting one of those as film work is quite expensive. Film editing is also quite expensive, which is why low-budget houses are watching HD prices fall. HD production is considerably more expensive than SD, but I think that it beats film these days.
On yeah, you obviously want to use an NLE station for editing since you mentioned several Mac audio programs. Final Cut Pro HD is apparently pretty nice, but be prepared to drop more $$$ on a decent edit station. We're talking G5 and fast multi-TB RAID.
That is not XEmacs. It is GNU Emacs. I use the Carbon port daily.
You also need to be fetching source from CVS to get the Carbon features, unless they released a new version recently. XEmacs is the old Lucid Emacs and a competely different source tree. XEmacs is truly kick-ass, but I don't believe that it has a Carbon port.
Opps. I stand corrected. XEmacs does have a Carbon port in 21.5.9 and later, but the main developer died on 10-Oct-2003. Very sad.

The USA is not a democracy.
The USA is not a democracy.
The USA is not a democracy.
The USA is not a democracy.
The USA is a Constitutional Republic operating on democratic principles. A democracy is three wolves and a sheep deciding what to have for dinner.
The whole idea of a "checks and balances" system is to prevent the will of 50% plus one from being imposed unjustly on the 50% minus one. This is especially true for the smallest minority group, the individual. The US is supposed to protect individual rights, which are completely counter to a "democracy."
As for your original point of "Get out there and vote." I agree whole-heartedly. The representative system is pretty broken right now, but politicians do pay attention when their jobs are on the line.
My whole home directory is automounted from a NetApp Filer. My user info is in NIS, which actually proved to be a bigger problem.
Mac OS X works fine with NFS mounted home directories in general. Jaguar broke loginwindow getting username/password info from NIS, but I just made a local copy in netinfo for myself. No one else logs into my machine at the console. A few applications don't like the HFS+ emulation done on single-fork filesystems. In my experience only Adobe Acrobat reader bitched, and there all I needed to do was force the Finder to create a resource fork. Then all was well.
My suggestion. Pick a brave volunteer and try it.
That's the only way to know if the applications you use will function OK.
Yes, NeXT/Apple prefers ObjC for the Cocoa userland libraries. Embedded C++ is used in the IOKit layer of the kernel because it was hoped that it would fix some shortcomings of the Objective C based DriverKit. IOKit is really quite nice once you get your mind wrapped around it, but the advantages of Embedded C++ haven't really shown up.
They had to disable templates, exceptions, and some other advanced features to embed a stable runtime in the kernel. Then Apple had to re-invent a lot of the dynamic dispatch stuff that ObjC uses. Drivers have been quite sensitive to changes in the IOKit base classes (fragile base class syndrome) that ObjC is mostly immune to.
It's hard to tell which is really better, because Apple has a lot more resources dedicated to kernel and driver programming than NeXT ever did.
I know it may be something you don't know if you're 16 and you're only familiar with "Dude you're getting a Dell" but for some reason (I'm sure those with marketing backgrounds can elaborate more than anyone wants) companies feel the need to put list prices that are out of the ball park. I guess so their customers feel they're getting a great discount or who knows. Anyway if you go to the SUN online store and you think that's what people really pay for those systems no wonder you're having a conniption. Of course not.
Government contracts require a published list price. You can not charge more than that. It's kinda like the room rates on the back of your hotel room door. The hotel is not allowed to charge more than the published "rack rate" for the room.
Of course, you're right. Serious customers never pay those published prices. They do like to see the "discount" on their proposal though...
You can see a picture (sorta) of this tape library at DST 812/814 library. Our other libraries have similar warning labels, but not quite as fun as the 812. I think they only show a hand getting crushed.
The warning on the DST 414, which is a 7 tape stacker, shows the gears mangling some luser's hand. It's quite vivid.
As you might have guessed, I work at Ampex in engineering. We usually take the sides off and bypass the safety interlocks for the 714 and 914 libraries, but not the 812. You just gotta know where not to stick your head.:-)
(Aside: All of these libraries use the same tape drive, a variant of this. The first digit in the model number refers to the robot type and the last digit refers to the density drive installed: 0 = single, 2 = double, 4 = quad.)
PVRs like Tivo and Replay, etc. are the exact same technology that the broadcasters use themselves. Many of the TV stations (and all of the big cable outfits) are broadcasting from "video servers" that are exactly like the PVRs except a lot more expensive. Yeah, the inputs are different as befits a professional machine (SDI or composite video, AES/SBU audio in many channels), but the function is the same.
Here's how a disk recorder is used in practice at insert big broadcaster here. New material is delivered on some sort of video tape, often DigiBeta, sometimes even old AMPEX 1 inch. That material is played on a VTR and digitized by the disk recorder into an MPEG2 file on its internal disks. Information about the clip is entered into an automation system so that the clip can be scheduled to air at the needed time(s). Usually that MPEG file is copied from the encoding machine to one or more playout machines over fibre channel or gig-ethernet. Sometimes that video clips is archived onto a computer tape library. (That's where I come in professionally.)
These professional video recorders are starting to outpace VTRs at least in broadcast. They are hideously expensive ($100k or more), but in all salient points are identical to a Tivo. They take normal video in, encode it to MPEG2 with no watermarking whatsoever, and record that on a hard drive or three. In fact the ability to move digital video files between machines at faster than realtime with no re-encoding is a big selling point.
The really ironic thing is that disk recorders were first used to insert commercials because you didn't have to prepare so many short video tapes. That's funny. I say that if the CDPT-whatever bill goes forward, we must make sure that professional video equipment is NOT exempt. Really put the fuckers out of business.
Actually I thought it was usually best to get out your Holland & Holland double rifle.

Hollywood also won't support any scheme that reduces revenue from Theatre box office sales and/or rental schemes. They are only interested in "movies via the internet" to cut Blockbuster and the video tape makers out of the loop.
However I certainly agree with TrollMan 5000. Broadband rollout has nothing to do with movies. Certainly desktop computers would have nothing to do movie delivery, and existing TCP/IP probably couldn't handle it. Think about 100 million people downloading a 4GB movie friday night, and you will realize what a strawman argument movies via internet really is.
OTOH, the technology is probably here today to make giant media libraries where every movie made or every song on every record released is available. Make your selections and have a CD or DVD delivered to your doorstep. Secure network delivery of video to your TiVo 12000 can wait. Building the libraries can and should start now. The storage investment is immense. I work on giant archives catering to the broadcast and gov't market, so I oughtta know, but the biggest cost is time spent digitizing analog video. It takes a very long time to do it right, but with open formats it should only need to be done once.
These huge libraries are what I want, and I imagine that other discriminating consumers would too. The undiscriminating will plunk down their $9.75 each Friday night to see whatever schlock Hollywood has regurgitated this week. Losing that revenue stream is why Hollywood is very interested in keeping old content buried and new content locked up.
The real weak link in the chain is ISPs as enforcers. How many ISPs do you know who'd relish that role?
I dunno. I think that AT&T, AOL, DT, and all the rest are quite looking forward to have a mandate to squash all opposing viewpoints and any competitors not willing to censor their customers. You can not run from this problem by moving to another country. All unrated content will be blocked from distribution in Europe or other complying countries.
Anquillia or other small countries which currently do not have nasty banking laws may be pollitically repressive. Check out the real power structure before jumping. In any case you will only be speaking to yourself since no one else can hear. Try to circumvent to filters and watch your little island get bombed out of existence to "save the children." As long as no currently popular ideas are suppressed, censorship even enjoys the support of the bulk of the population.
Mao Tse Tung was right about one thing, all political power flows from the barrel of a gun. Ultimately censorship laws are enforced by violence.
Those of you protest that this photo database is "no big deal" are right in a very isolated sense. If this project were a standalone artifact, the first of its kind, and nothing more, then it would be worth watching closely but no threat to any good person. It is not isolated.
The plan as I recall it, called for digitizing everyone in the USA with instant access terminals spreading throughout the land for customs recognition, check and credit card verification, "terrorist/kiddie porn/undesirable" stopping, etc. You hand over your national ID card, they swipe it, and a few moments later your picture appears probably with a lot of other information too.
Great. Now "no one can use your credit cards," is the selling point. Just remember that the same folks who proposed this innocent little "convenience" are also proposing registration of all guns and owners with confiscation promised, installing government backdoors on all computers to serve search warrants in advance of their issue, outlawing encryption where it is inconvenient, requiring national ID cards and their use for all government services and many private ones too, requiring banks to spy on your financial dealings, confiscating money and property without filing any criminal charges and then keeping the loot, and that is just what comes to mind right now. Oh yeah, it certainly looks like this same government is not above murdering its own citizens with incendiary devices because some tax agency needed a PR video.
Do you still trust them? What about the next administration?
All you European socialists want to chime in? It is illegal to own any encryption device in France or Russia. Russian ISPs will tell you that they can not operate without installing evesdropping software for the FRS (neo-KGB). We used to shudder at the thought of government spying like this. We still laugh nervously at the East Germans and the Stasi. Nearly a third of that country was informing on the other two-thirds. Of course that could never happen in America, and who cares if it does. We do not have death squads...
Computerization and universal networking are extremely powerful tools and can shape society in unexpected ways. Some folks have argued that this database is meaningless because the government is incompetant. Not everyone working for the US government is stupid, and many of these proposals come out of bureaucracies looking to increase in power or contractors looking to make a buck. Neither of these groups care about privacy at all. Add in large coroporate interests, who see negative value in individual privacy, and you have a recipe for disaster.
I would rather live in the society which did not feel compeled to track my movements, associates, financial dealings, personal communications, and very appearance. With a little forethought the same computer system which could be a powerful surveilence system can protect its users privacy and identity. The corporate motivation is lacking because provacy guards cost more and deprive them of potential revenue streams in selling your data. Goverment motivation for privacy is lacking because power and control increase with information. It is up to citizens to demand privacy and see that safeguards are enforced.
