Try the exercise. Choose one and then choose your tooling. If it's not C, C++, or Ada, I'll be surprised.

Assume you have a functional safety requirement for which a standard exists. What language implementation would you use that is certified for that standard?
633.
by buescher 4y ago
Sure, but safety-critical development is a different domain than vulnerability research.

>Unfortunately, safety code practices are highly dependent on your field and its practices, and I'm not aware of a good book or course. You mostly learn it by osmosis when joining a team that develops safety-related systems. You sho

Not open source, but Medtronic published a complete ventilator design and documentation, including firmware, in response to the COVID crisis.

Some of the reason the very rich say that is to encourage others to invest less in their own kids.

Also an important takeaway from TMMM: people were having the same problems and trying the same approaches to solve them over 50 years ago .

True, but you should be able to make 20 burgers for less than $20; easily if you already have condiments on hand. McDonald's burgers have 1.6 oz (1/10 lb) ground beef patties, and 80:20 ground beef is about $4/lb in most of

My barber just raised his price 25% for the first time in the 11 years I've been going to him. There's some sticktion to prices that's breaking free with the inflation we're seeing. I like to look at the USDA retail pri

I suspect a lot of the casual fascination with APL these days comes from frustration with Numpy. In the same way that nobody had anything good to say about Ada until C++ and Java were firmly entrenched.

There's a book. It's called The Birth of Tragedy. On the one hand, Nietzsche is pretty persuasive that, basically, tragedies are the highest form of drama. So, one would expect ambitious artists to want to tell stories with rea

Honestly, I was not a huge fan of 90s Microsoft, and I certainly never used this thing, but I really miss this kind of fun and whimsy and the bicycle-for-the-mind (even if you're only going to ride in circles in front of your house) qu

Well, sometimes, and more frequently now at really small process nodes, but mostly no. Most electronic failures are basically mechanical and thermal cycling will cause fatigue failures more than elevated temperatures will accelerate things

Yes. Of course, hearing is logarithmic and since a 36 dB reduction is six 6dB increments, the reduction from 11 to 5 makes sense.

I would expect Bose to get at least that right, but you never know these days. The Bose headsets in my house work flawlessly. I can imagine a monitor company getting it wrong.

Constructions are implicitly proofs, aren’t they? But yes.

From the article: "similar to GEOS on the Commodore 64". GEOS was definitely of the time. Also large memory expansion (i.e. >= 256K) kits, while available in the era, cost money and were uncommon. This system apparently runs

BBC Basic did not exist at the time; all Acorn had was Atom Basic. By the time your later Basics came around, Microsoft and the PC were already the extinction-level event for small business micros of the sort that ran CP/M. It's

If you can synchronize the clocks in the car and the key fob, it doesn't matter if you know the delta to UTC or not.

opensesame is clever, but it only works on fixed code schemes decoded with a shift register or equivalent. This vulnerability affects rolling code schemes.

I think bitC was significantly more than that but I never used it in anger. Years ago I came across another system, c-amplify, which was more literally a lisp syntax for C, intriguing but at the time wasn't able to get it to work. h
