on a regular basis, AdaCore people will post patches to the gcc mailing list with improvements to the compiler. they are in no obligation to do so, but they are good citizens. likewise, they also contribute to the core of gcc. a couple of y

the gcc version of ada is really good. unless you can't get a version of gcc for your target, it is probably OK for 'regular' (non high reliability, external certification) uses. if you want support, or support a target out o

How do you know how to use the new shiny things without real practice? My friend, we have all done this. (after about the 10th time the 'new technique' turns to a mess, you become very conservative about 'new things').

leaving out the discussion of how much force is required and how strong a pilot is, the hand crank for the stab trim has mechanical leverage. the pilot turns a crank that is geared to move a cable. the amount of leverage is determined by

Current 737MAX, 1 AOA sensor. As long as the pilot has been through the simulator with a run-away MCAS.

some would, some would not. those that have been doing aircraft software for 20 years probably have a fair knowledge of airplanes, aerodynamics, and flight controls. your comment expresses my feelings exactly on 'was this a software f

anything that is connected to the flight controls, is too important to sub out (unless you are subbing it out to someone better that you are). making an airplane is a huge endeavor that crosses across many domains. you have to have compete

kind of depends on how you name it. my understanding is the code 'worked per requirements', meaning it did everything that it was supposed to, as defined by the requirements allocated to it. for things like this, there is a layer

If they fail to recover the first time, that would be excellent. (the pilot thinks "wow, this is hard and I need to learn..") Pilots do not like to die. If the first attempt was incorrect, they will do it again. and again. and

Not a viewpoint I agree with. Boeing has plenty of business. 737 MAX sales may suffer, but that will not kill the Boeing Company. Aviation is a deadly serious business. Design is done by people, which are highly flawed cogs in the system.

Ever read a Tom Clancy book? Absolute crap. In about 3 dimensions. But, entertaining. Have read them all. Quickly.

Would you rather buy $100K of software from a "Senior Sales Representative" or a "VP of Sales, Western US region". Titles mean a lot to certain people, even if they are all puffery.

the usual definition of "legacy system" is a system that uses tools, technologies, and techniques that an organization would not use for new development. so, in SF, things change on a time scale of weeks. your 'go microservi

However the third iteration is something that you can be proud of. (but in my experience, 1/2 through the second iteration the funding gets cut off)

docker solves 2 problems. first is you have no control over your devs and allow them to install any software from anywhere. and second is you want to sell cpu time from the cloud in an efficient way (for the seller).

it wasn't software. the design of MCAS was done by systems engineers. they tell software what to write. it is called requirements. people make mistakes. the system / process is supposed to find them. if the process was not fol

they cost more than that ! (and note they run the same code as the aircraft, in most cases)

today, the plan is 'certify the process', not the product. people are assumed to be faulty.

by bdavis__ 7y ago
this was a systems engineering failure. nothing more. the system is designed to find these and remove them. it has not been determined if this is because of cost cutting or management pressure. could be, but it is also possible it is jus

parts stores deliver to mechanics and garages many times a day. no app needed, they use the phone. so, when you need a starter for a 1992 honda, they call the closest parts store and a 'parts runner' delivers it.

which in reality, is a pretty effective way to do it. Really. (speaking of airplanes)

good post. i agree that the main problem that autoconf solves has gone away. cmake is regularly a pain point. its own version, as well as how un-understandable and un-debuggable the cmakelist.txt files are. sharing code on unix systems

The amount of Boeing hate is phenomenal. "scrap the plane" ! "require a new type certificate" "never fly in a 737 max, no matter what". Boeing made a plane that conformed to all rules and regulations. As part
