I currently work hybrid. It reduces my effective pay by around 10%, which is a hell of a cut. It gains me nothing, since all meetings - even when we're all in the same room - are via teams, because company policy.

I see no added value from visiting the office.

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.

I dunno. China is a "market socialist" system -- which is a contradiction in terms. If China is socialist, then for practical purposes Norway and Sweden have to be even *more* socialist because they have a comprehensive public welfare system which China lacks. And those Nordic countries are rated quite high on global measures of political and personal freedom, and very low on corruption. In general they outperform the US on most of those measures, although the US is better on measures of business deregulation.

It makes no sense to claim Chinese courts have a lot of power, although it may seem that way â" itâ(TM)s supposed to seem that way. One of the foundational principles of Chinese jurisprudence is party supremacy. Every judge is supervised by a PLC â" party legal committee â" which oversees budgets, discipline and assignments in the judiciary. They consult with the judges in sensitive trials to ensure a politically acceptable outcome.

So it would be more accurate to characterize the courts as an instrument of party power rather than an independent power center.

From time to time Chinese court decisions become politically inconvenient, either through the supervisors in the PLC missing something or through changing circumstances. In those cases there is no formal process for the party to make the courts revisit the decision. Instead the normal procedure is for the inconvenient decision to quietly disappear from the legal databases, as if it never happened. When there is party supremacy, the party can simply rewrite judicial history to its current needs.

An independent judiciary seems like such a minor point; and frankly it is often an impediment to common sense. But without an independent judiciary you canâ(TM)t have rule of law, just rule by law.

Hereâ(TM)s the problem with that scenario: court rulings donâ(TM)t mean much in a state ruled by one party. China has plenty of progressive looking laws that donâ(TM)t get enforced if it is inconvenient to the party. There are emission standards for trucks and cars that should help with their pollution problems, but there are no enforcement mechanisms and officials have no interest in creating any if it would interfere with their economic targets or their private interests.

China is a country of strict rules and lax enforcement, which suits authoritarian rulers very well. It means laws are flouted routinely by virtually everyone, which gives the party leverage. Displease the party, and they have plenty of material to punish you, under color of enforcing laws. It sounds so benign, at least theyâ(TM)re enforcing the law part of the time, right? Wrong. Laws selectively enforced donâ(TM)t serve any public purpose; theyâ(TM)re just instruments of personal power.

Americans often donâ(TM)t seem to understand the difference between rule of law and rule *by* law. Itâ(TM)s ironic because the American Revolution and constitution were historically important in establishing the practicality of rule of law, in which political leaders were not only expected to obey the laws themselves, but had a duty to enforce the law impartially regardless of their personal opinions or interests.

Rule *by* law isnâ(TM)t a Chinese innovation, it was the operating principle for every government before 1789. A government that rules *by* law is only as good as the men wielding power, and since power corrupts, itâ(TM)s never very good for long.

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.

Class 1 and 2 e-bikes limit assist to 20 mph, not 15. You can ride them faster than that, but you have to provide the power. 20 mph is well above what most recreational cyclists can maintain on a flat course, so if these classes arenâ(TM)t fast enough to be safe, neither is a regular bike. The performance is well within what is possible for a fit cyclist for short times , so their performance envelope is suitable for sharing bike and mixed use infrastructure like rail trails.

Class 3 bikes can assist riders to 28 mph. This is elite rider territory. There is no regulatory requirement ti equip the bike to handle those speeds safely, eg hydraulic brakes with adequate size rotors. E-bikes in this class are far more likely to pose injury risks to others. I think it makes a lot of sense to treat them as mopeds, requiring a drivers license for example.

Would treating them as mopeds be so bad?

What weâ(TM)re looking at is exactly what happened when gasoline cars started to become popular and created problems with deaths, injuries, and property damage. The answer to managing those problems and providing accountability was to make the vehicles display registration plates, require licensing of drivers, and enforcing minimum safety standards on cars. Iâ(TM)m not necessarily suggesting all these things should be done to e-bikes, but I donâ(TM)t see why they shouldnâ(TM)t be on the table.

I am a lifelong cyclist , over fifty years now, and in general I welcome e-bikes getting more people into light two wheel vehicles. But I see serious danger to both e-bike riders and the people around them. There are regulatory classes which limit the performance envelope of the vehicle, but class 3, allowing assist up to 28 mph, is far too powerful for a novice cyclist. Only the most athletic cyclists, like professional tour racers, can sustain speeds like that, but they have advanced bike handling skills and theyâ(TM)re doing it on bikes that weigh 1/5 of what complete novice novice e-bike riders are on. Plus the pros are on the best bikes money can buy. If you pay $1500 for an e-bike, youâ(TM)re getting about $1200 of battery and motor bolted onto $300 of bike.

Whatâ(TM)s worse, many e-bikes which have e-bike class stickers can be configured to ignore class performance restrictions, and you can have someone with no bike handling skills riding what in effect is an electric motorcycle with terrible brakes.

E-bike classification notwithstanding, thereâ(TM)s a continuum from electrified bicycles with performance roughly what is achievable by a casi recreational rider on one end, running all the way up to electric motorcycles. If there were only such a thing as a class 1 e-bike thereâ(TM)d be little need to build a regulatory system with registration and operator licensing. But you canâ(TM)t tell by glancing at a two wheel electric vehicle exactly where on the bike to motorcycle spectrum it falls; that depends on the motor specification and software settings. So as these things become more popular, I donâ(TM)t see any alternative to having a registration and inspection system for all of them, with regulatory categories and restrictions based on the weight and hardware performance limitations of the vehicle. Otherwise youâ(TM)ll have more of the worst case weâ(TM)re already seeing: preteen kids riding what are essentially electric motorcycles that weigh as much as they do because the parents think those things are âoebikesâ and therefore appropriate toys.

OK, so much for that theory because I went ahead and searched the full text for wine and got this:

Mosquitoes showed a clear preference for the well-hydrated, on hops and grapes, that is. Arm landings were significantly higher in beer drinkers compared to those who had nobly abstained for at least 12 hours (FC 1.44, 95% CI 1.20-1.74, PFDR < 0.001, Figure 3C). Mosquitoes seemed to have a taste for wine drinkers too (FC 1.39, 95% CI 1.02-1.88, P = 0.035), but this effect sobered up after correcting for multiple testing (PFDR = 0.103). Measured blood alcohol concentration ranged from to 1.82â and positively correlated with the self-reported consumed number of beers (Spear-man rho = 0.46, P < 0.001) and glasses of wine (Spearman rho = 0.12, P = 0.011). No statistically significant effect of alcohol concentration was observed on mosquito attraction when included as a continuous variable (FC 1.04, PFDR = 0.853) nor as a binned variable using the concentration of approximately two units as a threshold (< 0.5â versus 0.5â, FC 1.21, PFDR = 0.344). Individuals reported to have smoked cannabis in the past 48 hours were more attractive to mosquitoes than individuals that did not smoke cannabis (FC 1.35, 95% CI 1.09-1.66, PFDR = 0.017, Figure 3D). Cannabis was the only substance for which an effect on mosquito arm-landings was found, the effects of other substances were statistically not significant (all PFDR > 0.569). There was no indication that the presence of a cannabis user made mosquitoes fly at higher altitudes or made them less aggressive.

Now I'm on to a new idea. Since hops and cannabis are related, there may be some aromatic compound common to both of them.

The drug companies didn't invent dementia. Alzheimer's was described in1906 and named in 1910, but there was a broad understanding before of older people going in to mental decline--even in ancient times. There's always going to be a leading cause of death. Increased health will lead to increased life spans and reveal new problems. That's what happened with senile dementia. More old people, so more people get it. Those same doctors and drug companies are working on cures and treatments ad yes treatments are more likely to come before cures. Take HIV for example. I'm pretty sure the people maintained at undetectable levels, leading near normal life spans are happier than when they got full-blown AIDS and it was a death sentence. Yes. There's still no cure and the drugs cost money; but they haven't stopped work on a cure. Any researcher in the field would be absolutely THRILLED beyond belief to have their name attached to that, or a cure for Alzheimer's. It's just that it's a really hard thing to do.

Yes. Alcohol. It's on their breath, and insects are attracted to it in general. Googling around, that includes mosquitos but I've heard of people using it to attract wasps and kill them even though it's probably counter-productive since you're attracting the very thing you don't want and the outdoors have a very large supply that your bug zapper or dish of beer is not going to exhaust.

That's the press doing its usual lousy job of communicating science.

The predictions aren't absolute, they are sets of scenarios for which probabilities are calculated. The longer we drag our feet, the more the set of plausible outcomes narrows. Take Syria -- Syria was a wheat exporter in 1990, but since 2008 or so has been unable to grow enough wheat to feed itself because of climate change when it had become dependent upon imports from Russia and Ukraine. This was early enough that likely we could not have prevented it even if we heeded early warnings in the 1990s when the current scientific picture solidified. We're not going to lose the entire planet in one go, it's going to be one vulnerable population after another.

It may seem like the climate crisis has completely fizzled to you, living in a large, wealthy, and heretofore politically stable country, but it is catastrophic for the people who have got caught. That's how the climate crisis is going to unfold: the rich and comfortable will be able to adapt to the continually changing status quo by moving their financial assets and supply chains out of the way, although you may be paying more for coffee.

At this point it's a matter of degree; we can't avoid problems now like countries being destabilized by climate change and generating millions of refugees. The question is how fast and how big a problem we'll have.
