How much do you trust your code?
-
I just got this in the email: a request to use my grid in a commercial app. "am developing an application for use in scripting professional fireworks displays" I don't trust my grid to show me the correct values in my homeloan simulators let alone trust it around 10 tons of high explosives. I don't even trust me around 10 tons of high explosives (I still have some scars to prove this is a valid fear). So it got me wondering: how much trust do you have to, and are willing to, put in your code? cheers, Chris Maunder
While I would not stake my code on anything more important than buying a troweling fork, I also would be a bit weary of staking someones life on, lets say, the .NET Framework, or J2EE or Windows for that matter. Can you imagine if half way through the fireworks demo the Office paperclip pops up, interupting a critical timed event, asking "It looks like you are a pyromaniac, do you want me to a: call the firebrigade, b: get more gasoline or c: call the paramedics?"

I´ve been using your grid for years on many applications. Regards Francisco Viella Silver at last!!

When I was developing life safety systems we couldn't have a critical controller that had programs resident in RAM or reliant on moving parts such as hard drvies.... Rule 1 - check the applicable safety standards, they appear for a good reason. Elaine :rose: The tigress is here :-D

Chris Maunder wrote: let alone trust it around 10 tons of high explosives Hmm, good question. Antother question should be: Do you trust windows???? :confused: I trust my code as far as I can see it. I have written an automatic system to recognise fire-alarms for fire-fighters an forward them to mobile-phones (via SMS). Another of my apps is involved in an fire alert system in a parking garage.... so sometimes I trust my code (sometimes...:sigh:)

The firealarm-system is just additional (we usually have special pagers), I just made it for fun (although it's very usefull and reliable, and it's running under 16bit DOS... ;) ) The other system is only a kind of park and guide system which handels an alert from an (certified) fire alert system and put infos on large scale displays (small pictures of it[^]) But thanks for your hints...

I trust mine more than I trust the NE American power grid and our Prime Minister. Goes to show how much I trust them ;)

LOL, Funny you should mention the Shuttle. I don't post much, but laughed out loud when I read this topic. I was changing jobs around 8 years ago and received a call from a head-hunter. After a few go-rounds, I was offered a nice 6fig plus salary working for a gov contractor. At first he would not tell me what I would be working on, but did after I turned down the offer. Seems I would have been working on the next generation of speed brakes for the shuttle. Cool offer and very lucrative, but I had just had a child, new house and could not make the move to another state. :(( Success is measured by ones ability to mask complexity with simplicity.

I once worked on a PLC Applications and Control system. The first version was written in Windows 3.1 and the version I was working on was an upgrade to 32 bit windows (NT 4). I was told by someone higher up in the company, that the Windows 3.1 version was being used by one company in Eastern Europe to control a nuclear reactor! :eek: :omg:
