Is there a business need for the level of backup that is being provided? Specifically, is the backup strategy in-line with the value of the data? No timeframe is given for your 3.5TB, so it is difficult to discern your exact needs.
Maybe the easier battle to fight is to reduce the level of data backup, and show how it can save the company money. Chart the growth in number of tapes in your backup journal, and see if it is getting out of hand.
Of course, if you ever DO have a problem, you will be fired, but... what are the odds?;)
While this sounds nice in theory, I think you are completely missing the boat. A "glut" of bandwith on the end-user level is like saying that you have a glut of bandwith on your gigabit network in your home, so you will host content P2P. Nevermind the fact that your upstream connection is a 56k modem...
There isn't a server-side bandwidth shortage; it just costs money. No matter who provides the content, if there is no cache at the point of upstream connection, bandwidth is wasted.
What I fail to understand is why more content isn't cached by ISPs.
Slow it down if you must, but wouldn't it be easy enough to integrate a heat pipe and have a warm case? With enough surface area on a case, I would think that it would be possible.
From a systems standpoint there is no reason for the screen size and quality to be linked to the "box." Someone may want a 21" flat panel, and someone else can get by with a 15" CRT. Also, when it comes to a server, there is not always a need for the monitor.
The airlines probably understand better than anyone...
Thanks, you really made me laugh! I doubt very much that the airlines understand anything about their business, especially when it comes to the "customers!"
What I fail to understand is why people need to be forced to change passwords at all: why are all these systems single-layered?
It only seems logical that smart-cards or java-enabled i-buttons... or whatever could provide improved security when combined with a password. I'm no cryptography expert, but it seems like a password or password hash doesn't have much more than 25 bits of real security.
Is it just hardware that keeps this from taking off?
Is there any support for password/smart card authentication systems in Linux?
Actually, it's lifetime of the box, or lifetime of the company... whichever is shorter! It isn't hard to imagine either of those being close to two years.
Sounds good; could also adapt fairly easily to finger length-- "home keys" need not be in a straight row. Could get a little confusing though without actually being able to tell where the keyboard would accept different letters at any given time...
In a mood to nitpick... 1. 5400/7200rpm. Although it would take longer to accelerate the platter up to speed with 7200rpm, it would not nesisarrily require more power (amps). The bearing losses would be higher, but possibly not as much as you would expect.
2. The same could go for the 3 platter disks; the platters themselves don't weigh *that* much to influence the draw.
The better approach is to actually measure the heat gain in a controlled environment over time for a variety of different usages. That is a little more complicated than just using a DC ammeter...
Don't list everything!!! Definately don't use 8 point typeface! 14 point is more like it! (Only slight sarcasm).
The whole point is that if real human beings are going through your resume, they just won't read it all! If they are ranked by computer on word "hits," well... maybe 4 pages will work... I really don't know much about these systems.
If you only have one page to give someone an idea if you are worth a one to four hour interview, or at least a follow-up call, you need to be efficient. While I would hardly say this is the parent's problem, don't put something in if it is just filler!

Undelete In Linux
·
· Score: 2
People are using trash cans and recycling bins as an excuse not to do proper backups!
For a single-user machine where no "production" work happens, you just might be correct. That all goes away when the machine acts as a file server!
What a proper undelete function (like NetWare's Salvage) does is not replace backups, but it does provide version control. Tape backups can give you a daily snapshot of a file, but just what appears at the end of the day.
User accidently over-writes a file they spent all day working on at 5pm? At least a lost day's productivity, but it could also mean a missed deadline! Snapshots, midday backups, etc. help with the lost productivity, but when there is a deadline crunch, the user having the ability to restore a file they JUST deleted without administrator support is HUGE!.
The elegance of Salvage is its transparency. A "recycle bin" does some things, but how well does it handle temporary files?
For a file server, functionality like Salvage really is essential!
The time we found ourselves using salvage the most at my old company was when we needed to get back to a particular revision of a document. Sometimes, the revisions were casual, just faxing something off to a client, and waiting for comments. You continue working with the document, possibly changing direction and making the previous issue irrelevant.
Although proper revision control procedures would save you, when a lot of things are happening at once it doesn't always happen.
Salvage is no substitution for proper backups, but it does bridge the gap when you need to get back a particular file from a particular time and day! (Not to mention the fact that it is immediately available from the user's machine, not requiring any administrative effort, changing tapes, etc.!)
Linus has insisted that there is no reason to support undelete at
the filesystem level, or anywhere in the kernel for that matter.
Don't delete important files and you'll never need the feature::-).
If you really need undelete, write a shared library that overloads
the unlink() system call and LD_PRELOAD it. This is the right place
to do it.
I think it is really a shame that Linux doesn't suppor this out of the box, but what does the above actually require to implement all of the novell-style functionality?
Namely:
Files only overwritten when space is required.
Every revision of a file is kept!
Is completely independant of a proper backup solution; the purpose isn't always to recover a file that was accidently deleted, but often to get back to a previous revision.
It doesn't seem like it can really function as a layer above the filesystem, or the tape backups would include all your revisions as well.
Companies that use this functionality love it... those that don't suffer blindly with the lost productivity.

"New applications and services that consumers want and businesses need will provide the tipping point for broadband demand and usage," says the report from the department's Office of Technology Policy....
Only 10 percent of U.S. households subscribe to high-speed access, lower than the rate in Taiwan, South Korea, Hong Kong or Canada.
I'm not sure about the connection speeds in Canada and Taiwan, but South Korea and Hong Kong have 10-100Mbit links, VOD, and more! The lobbyists need to find a better reason than content to explain the failure.
If the US did get a big deployment of 100Mbit links to the home, VOD would be easy (even HTDV), but I don't think there is really that much demand for it! Is pay-per-view movies really successful?
I think it is the net appliance end of the market that really needs work. Ditch cable and get your TIVO content off DSL? Ditch FM and get your music off the DSL? Simple appliances that extend the functionality are what we really need to make "mom and pop" go for it! Just using it on your PC doesn't give much value to most people.
Your expectation of "always on" internet is quickly dashed when you realize that you have to install a PPPOE adapter because your ISP decided to save a buck and not build it into the modem!
The ISP's have failed to deliver a value-added service where they needed to the most! I guess it isn't as much of a deal if you have a desktop machine, but with a laptop that goes between several different networks, it is really an extra hassle. They really should have up-sold the value of an instant connection.
I know that all it takes is a router in between, but for the "average" household with one PC that is counter-intuitive! Furthermore, the idea that an ISP a) doesn't support it, and b) practically forbids it in their terms! really just makes it an expensive dial-up line... which is faster, but... who cares for web browsing and e-mail!?
The easiest way to use something underwater is to go for a diving dry-bag system. There are ones that are waterproof to 40m with a mechanical fastener, and regularly have pre-sealed penetrations for headphones/remote controls/whatever.
Damned if I can find a good link now, though.
The problem with waterproofing things to make them actually submersible is that O-Rings are really required for a proper seal, and all penetrations have to be dealt with properly... it's a lot harder to change the batteries! Also, what constitutes "waterproof?" (For watches, 10m is "take it in the shower", 20m is "splash on the surface periodically," and 30m is something that you can actually take underwater... real diving watches are usually 200m.)
The problem is that if you try and put in a clause that rigid, it WILL scare your clients. The best way to approach it is looking at an acceptable level of change in specifications and schedule, with the understanding that the specification will develop through the course of the project.
If your goal is to profit off your client's stupidity... that's easy. Long-term relationships require profiting off of meeting their needs!
I understand the potential for it being legal if they are looking for items which are the intellectual property of their clients. Furthermore, I can imagine them having the "responsibility" to make a citizen complaint to the government on things like kiddy porn.
If they were investigating copyright violations (or any civil issue, in response to their client's requests), I can see how they could subpeona ISP logs... but not for the kiddy porn or any criminally illegal activity.
