Comment Hmmm (Score 3, Insightful) 51

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.

Comment Re:There is already a safe subset of C++ (Score 1) 86

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.

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.

Submission + - How USB-C Ended the Great Connector Wars (itbrew.com)

An anonymous reader writes: It's easy to forget the dark ages of peripheral connectivity. A twisted nest of proprietary connectors was the norm. Then, in 2014, a hero emerged: USB-C. It promised a reversible connector, high-speed data transfer, and enough power to charge a laptop. It was a revolution. This article from IT Brew breaks down the three waves of USB-C adoption, from its humble beginnings in the PC industry to its EU-mandated takeover of the mobile world. It's how a single connector brought order to the chaos and became the undisputed king of the hardware industry.

I do very much understand what you're saying and it certainly adds to the complexity. One cannot put sociological or psychological factors on a box.

That aspect of the problem is indeed going to be much harder to deal with than, say, salt, trans fats, or known carcinogenic compounds.

Honestly, I'm not sure what you can do about those aspects - financial incentives help a little, but honestly I don't believe they make a huge difference - which is why I've concentrated on unsafe levels of ingredients, because although we don't know exactly what those should be, we've at least got a rough idea for some of them. It's going to be a delicate one, though -- you don't want to overly restrict sources of sugar because diabetics can suffer from crashes due to excessively low sugar just as badly as excessively high levels, and some items get unfairly maligned (chocolate, per se, isn't bad for you, it's the additives, and indeed particularly high percentage chocolate can be helpful for the heart).

But, yes, I absolutely agree with your overarching point that the problems are primarily psychological and sociological. I just don't have the faintest idea of how these can be tackled. Jamie Oliver tried (albeit not very well, but he did at least try) and the pushback was borderline nuclear, and that was where there was clear and compelling evidence of significant difference in health and functionality. If you can barely escape with your life for saying eating better reduces sickness and improve concentration, and pushing for changes where these two factors essentially dictate whether a person is functional in life, then I don't hold out hope for change where it's more ambiguous or the economics are much tougher.

Comment An interesting problem. (Score 1) 76

There are papers arguing that smoothies aren't as good as eating real fruit because it seems that there's actually a benefit to having to break down cell walls, even at the expense of not getting 100% of the nutrients from it. However, cooking food breaks down cell walls, although obviously not to the same degree. It's not clear that breaking down cell walls is harmful, even if it's not beneficial.

A lot of ultra-processed foods have been accused of having unhealthy levels of certain ingredients (usually sugars or salt) and certain styles of cooking can add harmful compounds.

It would seem reasonable to say that there's a band at which a given ingredient is beneficial (analogous to a therapeutic threshold), with levels above that being increasingly harmful, eventually reaching a recognised toxic threshold. In terms of the harmful compounds from cooking, it seems reasonable to suggest that, below a certain level, the body's mechanisms can handle them without any issue, that it's only above that that there's any kind of problem.

So it would seem that we've got three factors - processing that can decrease benefits, ingredients that follow a curve that reaches a maximum before plunging, and processing that can increase harm.

Nobody wants to be given a complicated code that they need to look up, but it would seem reasonable that you can give a food a score out of three, where it would get 3 if you get maximum benefit and no harm, where you then subtract for reduced benefit and increased harm. That shouldn't be too hard for consumers, most people can count to 3.

Yeah, understood, food is going to vary, since it's all uncontrolled ingredients and processing itself is very uncontrolled. So take two or three examples as a fair "representative sample". Further, most manufacturers can't afford to do the kind of testing needed, and our understanding of harm varies with time. No problem. Give a guidebook, updated maybe once every couple of years, on how to estimate a value, which can be used, but require them to use a measured value if measured, where the value is marked E or M depending on whether it's estimated or measured.

It's not perfect, it's arguably not terribly precise (since there's no way to indicate how much a food item is going to vary), and it's certainly not an indication of any "absolute truth" (as we don't know how beneficial or harmful quite a few things are, food science is horribly inexact), but it has to be better than the current system because - quite honestly - it would be hard to be worse than the current system.

But it's simple enough to be understandable and should be much less prone to really bizarre outcomes.

Still, one shouldn't complain. America is, at least, moving in a sensible direction on train travel, which is an improvement over how things were in 2000 when the Federal government weren't able to get a number of States to build train lines even if the Feds paid for everything.

Comment Hmmmm. (Score 2) 36

It's basically a year to a year and a half off people's life expectancies, from the heat alone.

Although this is not trivial, the antivaxxer movement will likely chop 10-15 years off life expectancies and greatly reduce quality of life for much of the remainder, same again for the expected massive reduction in air quality that will result from modern political movements, and the absurd puritanical movement in the US will likely chop another 10-15 years off the life expectancies of women.

These are, therefore, substantially more significant, although politically impossible to deal with right now.

I fully expect that, if current trends prevail, by 2040, life expectancies will resemble those of the Neolithic and Bronze Ages.

Comment Due to circumstances (Score 1) 209

Attending work for 2 days means I pay £190 per week to work, with no recompense from the company. Because there's a decent amount of holiday time, my wages have only dropped £9000 per year from last year. If I needed to attend 5 days a week, I would have to leave the only job that I have ever held that actually made any functional effort to handle my disabilities. In other words, if I lost this job, I would not be capable of functionally working in any job at all, simply because most companes don't give a damn about disabilities. Legally, however, I would be deemed "capable of work". As such, I would have no wages and no benefits. Once my money ran out, I'd be on the streets. There is simply no viable alternative.

If a business guy thinks adding to the homeless is the best way to improve work morale, then maybe he's not a business guy that holds any opinion of value. He may well be listened to, which will cause a LOT of problems for a LOT of people and WILL increase unemployent and, in countries with failing industry, increase the homelessness of people who are far more competent than him, but that does not make his opinion valuable, merely incredibly stupid and sickeningly naive.

Submission + - 3 decades of satellite data confirm predictions of early sea level rise models (wiley.com)

Mr. Dollar Ton writes: Three decades of satellite-based measurements of global sea-level change enable a comparison of models and reality and show that early IPCC climate projections were remarkably accurate. Predictions of glacier mass loss and thermal expansion of seawater were comparatively successful, but the ice-sheet contributions were underestimated. The findings provide confidence in model-based climate projections.

Key findings:

* IPCC projections in the mid-1990s of global sea-level change over the next 30 years were remarkably robust

* The largest disparities between projections and observations were due to underestimated dynamic mass loss of ice sheets

* Comparison of past projections with subsequent observations gives confidence in future climate projections

Submission + - Recreating a Rare Mutation Could Grant Almost Universal Virus Immunity For Days (sciencealert.com)

alternative_right writes: The mutation, a deficiency in interferon-stimulated gene 15 (ISG15), causes a mild yet persistent inflammation across the body. Examining patients' immune cells revealed they'd had the usual run of encounters with flu, measles, chickenpox, and mumps, yet they'd never reported feeling particularly ill as a result.

Further investigation revealed their body's virus-fighting proteins were constantly on a low level alert, never really put away for later like in most people.
