Find some (a lot of) basic problems for which the longhand solution is known, or for which you can calculate the solution. As a heat transfer example, calculate heat conduction and heat transfer of spheres, radiant heat transfer between cylinders at odd angles, etc.
Make sure that that the program gives you an answer which agrees with the longhand solution. Vary the boundary conditions of your problem, and particularly check the limits of the boundary conditions, (zero and if appropriate, infinite values) to see if the program blows up in these cases (or gives bad answers.)
If you have access to competing analysis software, you can create much more complex problems and check that the answers match between software packages.
Try to create models with deliberate errors, and see if the software will find and remove those errors (zero size cells, etc) and particularly try to put in invalid boundry conditions and see if the software will point them out to you.
There are undoubtly case historys around where certain types of problems caused numerical errors in the solution, (the errors in the initial calculations of the stress profile of roller bearings comes to mind) you should seek these out and try that type of problem to see if the creators of your software learned from the mistakes of others.
Is this a vast amount of work? Oh Yes. But by choosing a well rounded test suite of problems, you should find most errors.
Internal Round cables have been around for ages for disks. They use twisted pair wires in regular cable jacket. The jacket is stripped off and an IDC connetor mounted on the cable as needed. Look in a fault tolerant Vax (now compaq) from about 10 years ago.(You must have one somewhere, right?)
There are round cables going to the DSSI bus disks in the disk bay. If you got SCSI disks, you have round cables as well.
The driving force for PCs has been cost, and putting connectors on a flat cable takes seconds. With round cable you have to manually dress out the wires, put them in the right order by color, etc. before you can terminate on the connector.
Round cables for external disks (SCSI) are very common even for PCs.
The Recount isn't done till the Democrats have won
I mean really, who among us would miss out on this spectacle? With electronic voting, elections can be stolen quietly and without fuss. With a paper punchcard ballot, Robo-Gore is going to have to work at it.
aside: Does anyone else find it hilarious that Daly is braying about election fraud? Anyone remember "Boss" Daly of Chicago? Plenty of links on Google..
My background is similar to yours, just add 20 years to the timeline, and escape (1958) from eastern europe with a briefcase..
But enough rambling.. The mindset which keeps people down in this country is the "cult of victimhood". The Democratic party plays this line to the hilt, promising yet another program to help the "victims". It's really sad, because by focusing on being "victims", people pass up opportunities to improve their situation..
Kind of funny when you think about it.. Democrats need "victims" to help. It there were no "victims", there would be no need for Democrats and their do-good programs. Ergo, Democrats must never actually fix any problems, because then their reason for being would go away.
Bush will make the internet tax moritorium permanent.
Robo-Gore (tm) will make us feel his bigger government.
Can you make a "kids heart dark"? Sure! It is normally done during wartime, the kids are taught to hate the enemy. Those who never got the history lessons (thanks , teachers union!) about Cambodia, Guana, and Germany can tune in the nighly news and watch kids throw rocks.
Can you do it over the internet? I don't know, but do images such as (warning: disturbing, will make you skip lunch at the very least) this and this (is porn, will offend you and make you say ouch) make kids happier and better adjusted? I cannot see how.
Since you are asking this question, you are not a "big-headed know-it-all". If someone you are helping thinks you are big-headed, that is a reflection of their insecurity, and I suggest you shrug it off.
If you want to really soft-pedal your stuff, you might point people to your software without telling them up front that you wrote it.. the smarter ones will figure it out for themselves.
As an aside, I wish more people making software available would give users an obvious way to thank/reward them in some way..
If a software author said on their web page that they collect local bumper stickers, or maps, or beer coasters, say so and I'd be happy to send some.

Just unplug your set.
Outrageous per-minute fees
Roaming Charges
Contracts which hide the true cost of the service.
Etc.
And why is easy to use for a beginner important?

You might put backups there, but not the data you need to work on.
Running what should be a local application over the network is a bad idea.
Keeping your critical data on a remote box only is a bad idea too.
Well, unless you are only going to buy one share, the change of price of the stock with splits does not matter..

Just for the record- I'm voting for Bush.
