One of the things that I think people underestimate is the importance of version control. Far too often data loss is due to somebody accidentally deleting a file they spent a week working on. With version control you should be able to revert and get back most of the work.
The other is redundant hardware. As people point out, RAID etc. only provides protection for the redundant components. If the controller, motherboard or such which is not redundant goes bad, you are screwed. The best solution is two servers with some sort of mirroring.
Another factor to consider is location. One of those servers should be off site somewhere so that if the sprinkler system goes off (or thieves get in) or a disgruntled employee gets access you don't have all your eggs in one basket. It might be as simple as having some employee with a company paid cable modem stick it in a closet.
Finally, you need to make sure that restores really work. Many times I've seen data lost because the restore process failed due to lack of testing, even though all the hardware and software was in place.
I think that the HP calculator design needs to be expanded to include APL. Why mess with all the strangeness of the various keystroke programming paradigms when modern hand held hardware is capable of an infinitely more powerful way of working. And yes, APL is a postfix language.
Like how reference GC's fail with circular references.
Java doesn't have that problem.
There is only one case I know of when Java GC fails, and it's pretty rare. If you create a 32 bit primitive int that has the same value as the address of an object, the GC won't delete the object. It's pretty rare for that to happen, and has been fixed in Hotspot.
There may have been no seizure but had he refused it possibly would have become an illegal search.
Then you call the ACLU, or talk to a civil rights lawyer about filing a lawsuit. Here is a link to a case describing what can happen to somebody who conducts an illegal search:
Tell them to locate the bug and find a work-around.
I think this is silly. The skills you really want in a programmer are the ability to keep up to date in new technologies, write clean code (that doesn't have weird bugs in te first place) and have a good idea of how to structure a program so that is easy to maintain. In fact, a really good programmer may well be poor at unravelling bugs because he has little experience in debugging - his code doesn't need a lot of debugging.
Is it just to remember to delete objects when you are finished with them, or am I missing something?
You are definitely missing a whole heck of a lot.
Problems with memory leaks in Java are the result of setting up conditions in your program that make the garbage collector think that an object never goes out of use. A typical example is a stack used by an object that persists over the life of the application that keeps growing as the application runs. Objects with references on the stack are never GC'ed because the JVM thinks they are still in use.
It's not the fault of Java despite people thinking that somehow Java should be immune to these sorts of problems. It's confusion on the part of people who mistakenly infer the term 'automatic garbage collection' to mean 'no memory leaks'.
Linux Administration Handbook by Nemeth et al. Her Unix System Administration Handbook is a classic. This one is targetted at Linux. Very nice. Great artwork too.
A big reason for this is that the local Indian economy is sustained by people who earn much lower wages. If you want domestic help you can get a live-in maid for $100/month. The guy repairing your car earns $3 per hour. Landscapers? $1.00/hr.
I think that anyone who went through school with a calculator is mentally unprepared. I've seen far too many people unable to do simple arithmetic without having to dig out a calculator.
To be honest I haven't found age discrimination to be a problem - I'm 54 and recently found myself unemployed through the failure of the company I was working for. I was able to get a series of pretty good offers as a senior level Java programmer within a couple of months. Pretty much all anyone asked about was my skillset. If you keep yourself up to date you should be able to find work.
The other interesting factoid is that the damages awarded were $0 because the Schmeissers did not spray their crops with RoundUp, thus they did not receive any benefit from the gene.
Wouldn't it just be cheaper to grade the tests at call centers in India? What are those Indians doing when there are no incomming calls? Just slacking off??? They could be grading tests.
I've been able to put together recommendations for family members that are pretty reliable as far as stopping viruses and various worms before they get installed, but not spyware. With spyware the best I've been able to come up with is tools to remove this crap AFTER it gets installed. To me that is just not an acceptable situation because the damage is often done by then. There is a real need to increase to security in terms of the install process. To me this is the real problem with Windows security right now.
Just last week I was offered a job porting a bunch of business rules written in MS SQL stored procedures to Oracle stored procedures at a nice fat billing rate.
Fight unemployment! Use stored procedures!
What is even better is when they break between releases from the same vendor. Ka-Ching!!

Well. at least this username/password doesn't work with a WG302 with firmware 1.5.

Derive quadratic theorem
The first thing I would say to you is 'what quadratic theorem'? There is a quadratic formula, but no such thing as a quadratic theorem.

Did you point out how much spam that would engender?
Put some instant coffee inside to see if I could go back in time....

Why is the cost of living lower in India?
A big reason for this is that the local Indian economy is sustained by people who earn much lower wages. If you want domestic help you can get a live-in maid for $100/month. The guy repairing your car earns $3 per hour. Landscapers? $1.00/hr.

Thanks Steve Wright..
you have been astro-turfed
More like infomercialled.

I just used it in Mozilla 1.6 without a problem.
My point, which you quoted, was that:
"You can't do much with ***___JUST___*** XWindows."
Yes, but that is not the issue. You want to name it GLX, but X is not always a critical component. Just GL works fine in many applications.
Wouldn't it just be cheaper to grade the tests at call centers in India? What are those Indians doing when there are no incomming calls? Just slacking off??? They could be grading tests.
You can't do much with just XWindows.
You can do a lot without XWindows. any distros have an option to install Linux without X for use on servers.

I've switched to SuSE FTP installs for my desktop machines because the other free choices don't have 3rd party vendor support - no Eclipse, etc.
Eh -
Just last week I was offered a job porting a bunch of business rules written in MS SQL stored procedures to Oracle stored procedures at a nice fat billing rate.

the company should allow their employees to dedicate 1% of paid time
What a load of shiieeete. Charities need money. Volunteers are easy.
so where does that leave me? i've got a rh9 that is end of life and i reall don't want to switch to the debian chaos
- Fermi LTS
- Suse downloadable versions
- Whitebox
- Fedora community support for RH9
Are all interesting options.
