Comment Re:There is already a safe subset of C++ (Score 1) 30

Ish.

I would not trust C++ for safety-critical work as MISRA can only limit features, it can't add support for contracts.

There have been other dialects of C++ - Aspect-Oriented C++ and Feature-Oriented C++ being the two that I monitored closely. You can't really do either by using subsetting, regardless of mechanism.

IMHO, it might be easier to reverse the problem. Instead of having specific subsets for specific tasks, where you drill down to the subset you want, have specific subsets for specific mechanisms where you build up to the feature set you need.

Journal Journal: Antiques being melted down 3

A restoration expert in Egypt has been arrested for stealing a 3,000 year old bracelet and selling it purely for the gold content, with the bracelet then melted down with other jewellery. Obviously, this sort of artefact CANNOT be replaced. Ever. And any and all scientific value it may have held has now been lost forever. It is almost certain that this is not the first such artefact destroyed.

The problem in California is that private lawyers realized they could sue almost anybody for failure to warn about carcinogen risk. The result was that everybody (both private individuals, companies, and government facilities) stuck a warning on virtually anything. The initial intention of the law was good but very badly worded.

Uranus an ice giant? Yeah, indeed Wikipedia does confirm that it is an ice giant rather that a gas giant. You learn something every day!

But just how do you get rid of all those ice cubes in your underwear then?

Ok, but then wikipedia confirms that methane is still the third-most-abundant component of Uranus's atmosphere

Someone pointed out some differences in Idiocracy: a primary plot point was that the President actively recruited a cabinet member for intelligence, without knowing what that cabinet member would recommend, and willingly followed the possibly unexpected advice provided by that cabinet member, and actively and accurately observed and judged results both when the cabinet member made a correct and when they made an incorrect decision.

It is considerably safer to treat stop signs as yield signs for (human-powered) bicycles. By far the most dangerous thing at intersections is being hit by cross traffic while they are moving at the low speed that they have to from a stop. Some states have decided to rewrite the laws for yield-on-red.

Some e-bikes certainly have enough acceleration that this is not a problem. IMHO these should be subject to motorcycle regulations and this also means they must travel in the car lanes.

Submission + - So many birds are migrating that they're appearing on weather radar (washingtonpost.com)

alternative_right writes: Between 2010 and 2013, the radars were upgraded with technology that allows both horizontal and vertical pulses of energy to be emitted. By comparing the returned signals, meteorologists can determine the shape of whatever is in the sky. Raindrops are a bit wider than they are tall, and shaped like hamburger buns; snowflakes are — obviously — flaky; but lofted tornado debris is spiked or jagged.
Birds, meanwhile, appear as somewhat spiked objects, as do insects. But insects appear a bit more round and uniform on radar, and are also lightweight enough to become caught up in the wind. Birds travel higher than most bugs, and also can fly against or perpendicular to the wind. After all, they have places to go — southward. Meteorologists can also determine their direction of motion through their analyses.
