How many of the guys know about Reliability engineering? Do you or your company follows this to showcase your product/services?
I just wanted to know if it would be helpful if I write an article on this wrt to software?
I was into software developement (Good old VC++ with MFC) and thats how I got introduced to Codeproject. But 5 years ago, I had to change my direction in to core enginnering to protect my job from overseas developers. It was the difficult initial years to keep my head above the water and grasp the whole concept.
So just wanted to know if these kind of articles ( mostly consisting of abstract concept, formulas and statistics) will be welcomed or not?
cheers,

Yes - if you can write an article around the concepts, formulae and statistics I'd definitely like to read it. It is something we should look to apply in software development.

Write it, but maybe it should be a Reference? And try not to rely heavily on graphics and charts.

Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

OK, so we had a messy, messy day here with a deploy that went pear-shaped, so I was wondering if anyone has any true horror stories of deploys that went terribly, horrifyingly bad. The sorts of thing where you no longer even visit that town because the Wanted posters are still flying from the street posts.

I have cleaned up after plenty of people who have had deployments go sideways. So far, knock on wood I have always had a good back out plan.
Common sense is admitting there is cause and effect and that you can exert some control over what you understand.

The worst deployment I remember involved an act of nature in the middle of a software upgrade on a client's site. The installation required a copy of the client's data on tape for reformatting of certain data files. As luck would have it, the building was struck by lightning, causing damage to the tape in the middle of reloading a critcal index. For reasons as yet unknown, we discovered that the client had not backed up their data for three months prior to the incident. Since I was on duty during the holiday weekend, I was stuck with the task of salvaging the damaged index file from the raw data that survived... a seventeen hour marathon.

Back in the day, the company I worked for wrote software that was "deployed" by a custom-cut CD to around 100 remote locations around the state. We had no control over their environment (other than to specify it was PC/windows 9x). The bloke developing that software cut the cd's for go live, then went on a month's vacation - overseas and unreachable.
Needless to say, the go live didn't go very well, and yours truly was tasked with cleaning up the mess - some very, very long hours over a few days to get it under control enough to cut a new set of cd's and try again, followed by the remainder of the month working on performance issues. (OT: under a quirk of the wage agreement I was working under, because I didn't have enough of a break between going home and returning over a few days, by the third day I was working on QUADRUPLE time... go me!!)
The bloke returned from holidays, dropped a resignation letter on the manager's desk and walked out again.

No great loss, he was a douchebag anyway!! Funny story, after he left, we had to clear out his desk, and in it, found a hand written list of porn titles, around 1/2 of which were crossed off... At least that explained the lunches away from his desk and returning smelling a little funky...

Here in the UK, he wouldn't be called a 'douchebag', he'd be called a 'wanker', which in this case is very fitting!

I enjoyed reading this as much as I pitied you. Try script writing my friend but remember the end should be a better one than the story is.

I once worked on a support site for a computer manufacturer that saved over $300,000 a day in phone support costs. I did a deploy that caused tons of lockups, server reboots and downtime for a few days afterward. We were pulling our hair out trying to figure out the problem, and had no idea.
We eventually talked to someone in tech support, and they let us know that one of the popular pages would hang if you clicked go without entering a serial number. They let me know they had a web page spinning on it to see if it would return all the systems. 
I had removed the front end validation because I thought it was redundant to check what the COBOL service running on the mainframe was going to check anyway. It wouldn't have been a problem, but there were multiple entries in the table with missing serial numbers and the service expected the index to be unique.
Needless to say multiple patches to multiple layers of software were quickly deployed.
