I worked on a 750,000-line troop deployment readiness application called MedBase for the Great Plains Regional Medical Command, as well as designing and developing a trauma center patient tracking system used at Brooke Army Medical Center in San Antonio. I also co-developed the Readiness module for the AHLTA program.

I wrote a controlling module for a medical device that might be unsafe for a patient if used improperly.

Medical Imaging and Pharmacy Dispense systems are classified as medical devices and are regulated by the FDA, but Patient Tracking and Order Management systems are at the mercy of the hospital employees who configure them. Most (human life) liability seems to be pushed to the hospital clinical staff as they are ultimately responsible for patient safety. If you have good processes (documenting due diligence), healthcare is a great market with grant money waiting for quality software solutions.

I have worked on tower cranes anti-collision system before. The crane's arm is not supposed to go out of the construction site boundary and is supposed to brake before it collide with another crane's body or arm. It is mission-critical and life-critical system(hardware and software).

These two worked for EDS at NASA and worked on the telemetry logic. Had the astronaut's lives in their hands. Testing was thorough, far more thorough than you'd do for a commercial application.

I work in a company that develops control & simulation software for oil and gas pipelines.
I have not written any code that opens and closes the valves and the like but I have created control displays that show different data points. Based on those, the operators make decision as to what to do, so you can say I've done mission critical programming.

Worked on a DOS based app that collected data that monitored babies in a nursery or NICU (Neonatal Intensive Care Unit), and would set alarms and alert the nurse's station if anything went wrong. It actually used sound cards for collecting the data... sound blaster 16's I think, back in the day. Yikes. I didn't have kids at the time, I think I would have been a bit more nervous if I had. Was weird seeing the modern equivalent monitoring my first son when he was in the NICU after he was born (he's 4 years old and fine now).
We kept trying to call it Babycomm but the company who contracted us didn't like it.
He said, "Boy I'm just old and lonely,
But thank you for your concern,
Here's wishing you a Happy New Year."
I wished him one back in return.

I have worked on maintaining diabetes support applications. It greatly helps diabetes patients, but I don't think it will be used in life or death situations. Patients still rely on their doctors and medication and only use the application to make it easier for them to keep track of bloodglucose measurements, etc.
It does give me a feeling that I am doing something useful 
|

Tell that to my wife. Her doctor changed the types and quantities one day, and the next day I had to race the ambulance to my house when she was in diabetic shock.
Currently, my wife's management is done on a week to week basis, powered by Excel. Her glucose control is now considered Very Good
|
|
|
|

It may sound really bad, but doctors are sadly still human too.
I hope all is well now and hope that doesn't happen again.
I personally think that it is a good thing that diabetes patients have all these ways of helping them to keep track of their personal health. Be it an excelsheet or an application.

I presently have a big hand in developing code which will ultimately assist autopilot functionality in small sport aircraft (e.g., Cessna). If knowing that if you reverse a couple reception bits and coming up with a completely wrong sensor value and thus, the aircraft doing unexpected (and potentially fatal) things isn't pressure, I don't know WHAT is!

I see there are a lot of people developing very interesting software. Which computer programming languages do you mainly use for your software developing in this area? I would say that if you have a standard hardware, then the computer programming language Assembly would be interesting, but otherwise I wouldn't wonder if you prefer Ada or Haskell.
Have a nice day on!

Most of my apps are .Net based; and written in C or VB. I do quite a bit of javascripting when needed, but I prefer server side code for my internet apps

You definitely noticed that the question was just about computer programming languages for software critical to human safety?

Noticed it I did- I have migrated from the designed-for-and-used-by single user applications to net based services that are being called upon by the emergency services sector internationally

Many moons ago I attended the launch party for Office XP and got a copy of that and of MapPoint 2002. I started up a DB project which had everyones addresses in Access when I became a volunteer FF- so I extended it by adding in the MapPoint Control. Soon I had my own navigation system.
As nothing is never good enough, I expanded the DB to contain the hazardous materials kept at local facilities (eg acetylene at the local garage) and I extended the mapping portion to draw out evacuation zones if whatever was spilled
Now that everyone and their brother has access to online mapping and imagery, I have migrated to using SQL for the backend and I am using MS Virtual Earth for the display, to the point that I have a working version that will plot in 3D the plume released from a spill
The neat thing was that in the metro areas where there is 3D imagery available, you can have situations where the ground floor is in the evacuation area but the roof is safe

I do software systems for fire and gas detection/protection and emergency shutdown systems. Most in PLC logic and some (well tested) C. An oil rig dumping it's entire inventory of oil and gas to flare is an amazing sight

yes, this kinda of stuff only works with PLC.
try the same with .net or windows and you have a diaster

You might be surprise at the number of processes controlled by PC based windows applications. Most are supervisory applications rather than hard real-time, but the use of windows and even .NET applications is quite common for tasks that don't require pre-emptive RT or hard 365/24/7.
Most large scale industrial control systems use windows in several capicties, like the HMI, and the build/load/supervision environment for embedded controllers. Some even do direct process control (mostly for slow processes where fast response is not a big deal).

I do the ballistics for rockets. It is my job to make sure they land where the user wants them to, and do not run into mountains on the way. (Olive-green rockets that go bang when they land.)
Obviously I do more testing than coding. (Testing rocket launchers is rather fun, as a matter of fact, if you have earplugs.)
Before you ask, no, I have no problems at all working in this industry. Because of us there has been no war in Europe for 60 years - that is a record.

What about former Yugoslavia? Don't you think the conflict there was a regular war, or don't you count balkan to be a part of Europe?
Of course, this discussion belongs to soapbox, but I couldn't resist when I saw such a statement.

Quite right, mea culpa.
