Now I play admin on 110+ machines, and I stay bored. Why? Because I've written a response engine in Expect that handles most of my everyday problems. I call it AGE, Automated Gruntwork Eliminator.
Boredom is good. Boredom means nothing bad is happening. If you want to not be bored, do something stupid.
I have been interested in learning how to write scripts in Bash. Any recomendations?
For those of you running on crippled (MS Windows) systems here it is:
CRON(8)
NAME
cron - daemon to execute scheduled commands (Vixie Cron) SYNOPSIS
cron DESCRIPTION
Cron should be started from/etc/rc or/etc/rc.local. It will return immediately, so you don't need to start it with '&'.
Cron searches/var/spool/cron for crontab files which are named after accounts in etc/passwd; crontabs found are loaded into memory. Cron also searches for/etc/crontab and the files in the/etc/cron.d/ directory, which are in a different format (see crontab(5)). Cron then wakes up every minute, examining all stored crontabs, checking each command to see if it should be run in the current minute. When executing commands, any output is mailed to the owner of the crontab (or to the user named in the MAILTO environment variable in the crontab, if such exists).
Additionally, cron checks each minute to see if its spool directory's modtime (or the modtime on/etc/crontab) has changed, and if it has, cron will then examine the modtime on all crontabs and reload those which have changed. Thus cron need not be restarted whenever a crontab file is modified. Note that the Crontab(1) command updates the mod­ time of the spool directory whenever it changes a crontab.

Then Newton would have joined the idle rich. Remember, he was rich to start with. From what you are saying, he would probably have bailed out of the university system before he got an undergraduate degree.
Welcome to the 21st Century World Wide Totalarian State. Please check your privacy at the entrance. Since this system is administered by non-humans, human weaknesses will not be tolerated. Have a nice day.
I used to work in a cGMP compliant lab. One of the big issues was the verification of all software tools used for data analysis. The best method of verification is of course, to audit the source code. This was not possible when applied to spreadsheet and other closed source software. As a result we had to WASTE YEARS OF OUR TIME CALCULATING THAT SHIT BY HAND!
Once we had verified that we had a large enough data sample that showed the software performed accuratly, then we could trust it.
Open source tools would have allowed us to signifigantly speed up the verification time.
Live by the internet, die by the internet. Just because someone claims to be against the RIAA doesn't make them your friend. Just because someone is against SCO, doesn't make them about free software rights.
True. They can be against those organizations for the simple reason that they want all Americans dead.
Just where would we be today if we could treat source code in the same way we treat mathematics?
I rather think the proprietary experiment has provided some valuable information. It has demonstrated that for information systems the best model of development is the peer reviewed open model used until recently in science. Of course now the trend is back to the guild mentality of the middle ages.
Jerry Pournell write great military science fiction. In all other respects he should be assidiously avoided. On the political spectrum he is somewhat to the right of Franco.
Wasting time, sure. But at least it's income. He's blaming other people for his problems, but there are many people in this world who would love to have a job at McDonalds, here in the land of opportunity. You can be short-sighted like this guy, or take what you have and make the best of it.
McDonalds pays about $6.00/ hr. Try to make a mortgage payment on that. McDonald relies on the labor of teenagers (who have no bills) and retierees (who have paid all their bills). Anyone else who works there is just slowly sliding into welfare.
Unfortunatly I did poorly in spelling. I did mean to fascism. And yes when corporations run things it will be a totalitarian regime. Democracy is not a goal, it's a process.
It has long been accepted and promoted by internationally minded people within the electrical utilities that power could be shared internationally in a global HVDC grid that would be both technically and economically superior to the primitive, isolated systems that predominate today.
Let me see if I got this straight. The electrical grid is now so large that it has become subject to problems of sensitve dependence on initial conditions, and you want to increase the size and complexity of the electrical grid.
What will you say when instead of whole nations being blacked out at a time it's whole continents?
Since the problem is expotenial in nature increasing the number of nodes and lines will ensure more large scale blackouts. Also places that do not invest sufficiently in upkeep will hold the rest of the system hostage.
I can see the upshot of this proposal now, wars being fought over grid upkeep and administration.
Here's a counter proposal, decrease the size of electrical grids. It will encourage upkeep because the locals will KNOW who to blame, and local problems will stay local.
Do you really want your electrical grid in Italy held hostage by a tree in France?
Countries governed by corporations will likely end up having priority electricity and supply for corporations and crappy, practically unmaintained electricity networks for the general public, except for people who pay a generous amount of money or have a large share of company stocks.

Don't worry we have Groo.

BTW, is rocket science more difficult than Quantum Electro Dynamics?
Thanks.

Don't swear, just break the system. Toodles.
Can you get me some of what you're smoking?

Darl my good man! Hold my Kite string for me.Thank You. Ben
You would never get published without a University backing you.

Yes, back in the days when manufacturing was actually done in the USA! This time we just made other countries richer.

I am never forget the first time I meet the Great Lobechevsky. In one word he tells me secret to success in mathematics,

It's called Facism.
