Your point is wrong. C was /not/ intended for safety critical applications. Therefore, it makes sense that using it in that context will require adaptation. For Ada it does not. It’s tire patching.

C and C++ were not designed with critical applications in mind. Therefore you cannot apply the same criticism to them. SPARK is a proof that something is wrong. If you have to restrict the language to attain the goal of the language, that’s

Ada is really in a bad place. It’s too generalist for safety critical applications. A DSL is a much better fit, restricting operations and possible side effects to a minimum. At the same time, it’s very abstract and somewhat esoteric, meani

It’s very common. Top management in large political orgs do not want to be associated with a failed project. They will spend the first days actively covering their tracks. Once this is done, they usually send HR to clean house. Unions stay

There is a solution to this problem, known for a few decades now: the vital coded processor. Basic idea: each operation can simultaneously compute a result and an arithmetic « signature » that can be pre-calculated for a program. The length

Well, yes and no. In my opinion, lobbying in itself is not evil if it remains within reasonable limits. One of the limiting factor is to avoid giving the said lobbies unlimited funding. That is one of the reason for taxing corporations.

I find ironic to portray as extremists journalists who report on a company that pays zero (0) taxes on revenues expressed in billions. I would rather apply the adjective to the reported company for some reason, but maybe we have different m

Taxing mega corporations is essential. I would add that you need to tax them to oblivion after shareholder’s expectations are reasonably satisfied. If you don’t, you essentially create rogue institutions with deep pockets that will attempt

Spot on. By the way, one can purchase multiple units (brand new) for 1.2M€ per car, and that’s before negotiating. 2.5 is really expensive. And I am talking European price, not Indian or Chinese.

There is a difference between vulgarisation of science, and making money out of sensational unproven claims pretending it’s science. This is my moral compass in that matter.

Driving is unsafe if humans drive because humans make mistakes. It should not be when machines do. Otherwise, what is the benefits of using them? Driverless cars can, must and will be held to a higher standard. But it is not a lofty ideal,

Pay your taxes so that your military can keep an eye on the assholes who do this, and so that UN may offer some form of asylum to their victims. Vote for politicians that oppose this shit publicly. Explain to your kids why this is wrong.

Grain silos are actually built to withstand explosions. I am not an expert but I was explained as a kid that stored grain can create static electricity discharges that can result in self-ignition.
