As an aside, it’s amusing to see the people arguing against Ada because they don’t see the value in decreasing the chances of human error. Even the old UNIX command line programs from the 1970s, written by the gods of programming themselves, are still bug-ridden and they are still getting software updates even today. There’s no “we’ll fix it in the next release” with that. The RVV-enabled VPU enables a “powerful instruction set with scalable data sizes, and flexible microarchitecture implementations, and leaves memory subsystem decisions open for system level optimization,” says the company. She told him they weren’t home and he, without missing a beat, tried to start forcing his way into the home. How is linkedin doing now? An intermediate selection process picked the two most promising approaches, with ultimately one language emerging as the victor and given the name ‘Ada‘. Microsoft: 13 As he sits up in bed he notices that the door to his room is ajar. Questions such as: Is that pointer parameter for a single item or a list? Ada promised the world, and Forth promised “tighter code than assembly language,” which may have been true if you wrote sloppy assembly. In the end, which instructions you ask the CPU to crunch will determine not only the quality of the design, but the complexity of the code and the difficulty of both the implementation and maintenance phases. During this time, Jonathan’s best friend Nick was sitting at the breakfast table eating cereal. I didn’t think anything of it at the time, I figured it was maintenance if some type. A few weeks ago my girlfriend and I were sleeping together, when I woke up to her saying “What are you doing?” She sometimes talks in her sleep, but this sounded so coherent and urgent that it jolted me awake and I asked what she was talking about. (Do you comprehend, are you interested to fix any bug/regression found in a GNU C-ishh legacy project or something like Boost?) Not so for Ada: This would make the Ada compiler throw a nasty error, because ‘Integer’ and ‘MyInt’ are obviously not the same. Here in the real world we have actual customers who rely on working product, they will not pay for the product without proper documentation, and they will not adopt it if they find bugs and we cannot fix them and turn around new builds in a timely manner. The C++ at SpaceX is probably using a very precise and boring subset to get across approval for mission critical standards so I would not be too fast celebrating C++. The PolarFire SoC uses a modified version of SiFive’s 28nm fabricated, 960MHz to 1.5GHz U54-MC quad-core complex, which also powers SiFive’s Freedom U540 SoCs on its HiFive Unleashed board. But hey, you really think the C/C++ they choose 10 years ago did not suck..? I realize there is a “good” GNU Ada compiler, but it produces C as its intermediate code, like Niklaus Wirth’s original Pascal compiler producing p-code.

They defined a bit-field where the interface (that I wrote) specified that UNUSED bits be left ZERO for backward compatibility, so the Ada guys just those bits “unspecified”. When software has bugs, either design or logic, people have died. Today, software written in Ada forms the backbone of not only military hardware, but also commercial projects like avionics and air-traffic control systems. Sometimes I’d hide in the closet of a room where someone had recently died (their body and belongings long gone in the empty room) and I’d press the call light and wait. And tell me, when someone from inside MS finds a bug, do they file a CVE? My mother swears this is a true story, and frankly, I don’t see why she would lie about it. Ada has good marketing, but anyone interested in it should read C.A.R. Below are 10 short scary stories from posters on Reddit. After working with ADA for over 5 years on flight deck software, a lot of the points you make in favor of ADA are actually things that infuriate me.
