This is an astoundingly vapid article. If you want to understand why and how the UK has so quickly reduced the amount of coal it burns, Carbon Brief has a much more informative overview [0].

The basic explanation of what happened is simple: the UK instituted a carbon tax that made coal more expensive than natural gas per unit of electricity produced, so British utilities shut down their coal plants and replaced them with gas plants as quickly as possible.

The backstory is somewhat more complicated, and much more interesting. The British tax was implemented in 2013 as a local fix to a broken EU carbon-trading program; that program, called the Emissions Trading Scheme [1], allocated to electrical utilities in the EU the right to produce a fixed amount of carbon emissions (and carbon-equivalent emissions), and the rights were made transferable—a typical cap-and-trade set-up. And then the basic problem with that typical set-up occurred: the fixed supply of rights to produce emissions proved higher than the EU's electrical sector's total demand, a consequence mostly of lower than expected demand for electricity during the recession that followed the financial crisis of a decade ago, but also partly due to other clean-energy initiatives and to big changes in world energy markets. And so the price of emissions rights collapsed.

That wasn't really a problem—no more carbon was being pumped into the air than the ETS allowed—but it made plain the fact that the ETS was doing nothing at all to reduce emissions. So British lawmakers decided to implement their own carbon tax, called the Carbon Price Floor [2], in order to reduce emissions and support the development of clean energy. The tax rate Parliament set was one of the highest in the world, and as it turned out it was just high enough to make coal slightly more expensive than natural gas for generating electricity, an outcome entirely unforeseen when the policy was decided, just as global production of natural gas was beginning to boom and its price to plummet.

So in the end, a bunch of poorly designed policies and their unforeseen consequences led to a better than expected outcome: Britain has been weened off coal decades earlier than was thought possible.

Your facetious claim was that understanding how a modern computer works is best done by learning C. I said it's best done by learning how a modern computer works with classes on computer architecture with intros to fundamental techniques. The comment I'm replying to has good detail on ways C maps to computers better than most languages. Original claim is still false across the board where people capitalizing on underlying hardware are better off understanding various forms of computing followed by languages that take most advantage of each or most of them.

I don't know Grothendieck's work, but this sounds like "pointless topology" for which I know a pretty good example (I also have Johnstone's book but it's terribly difficult for me to get into).

Consider the "set" S of all surjections from the natural numbers to the real numbers. It should be immediately clear that no such surjections exist, thus we have a "set" of no points. That said, suppose we'd like to talk about the properties of this set nonetheless. Are there any?

Instead of working concretely, we can work logically. Instead of discussing individual points, I'll name properties these points might have should they exist. For instance, I could talk about all of the subsets of S such that (s in S) has that s(n) = r for some values n and r. There are NxR such properties, one for each choice of n and r.

These properties can also be combined. I can talk about (n1, r1) AND (n2, r2). They in fact form open subsets of S and thus a topology of this "pointless" set S.

So in this way, I actually can discuss quite a lot about S despite it having no concrete points. I can even construct another set S' which does have all of the points needed to support the "properties" I was discussing earlier. S and S' are related in that much of what we can say about S' we can "port" over to S, so in some sense the points of S' are "phantom points" of S.

And this sort of thing is what I think Grothendieck began doing.

No, I’m talking about stuff like https://scholar.google.com/scholar?q=mesopic+efficiency (add keywords about street lamps and car headlamps if you want more recent and specific results). The relevant literature is mostly from the past few decades, and ongoing.

Luminous efficiency is not the only thing we should care about here. What we want is for the road and objects on it to be clearly visible to someone with dark-adapted vision, and for individual sources of light to be visible but not cause glare or distraction. Obviously a brighter light does a better job of making itself visible and illuminating things directly in its path; the problem is that brighter lights which are intense in the blue part of the spectrum cause more glare and more adaptation than dimmer yellower lights, which makes everything that isn’t being directly lit by them effectively less visible. If objects directly under the sweep of car headlamps are lit to the same extent as during a sunny day, then the shadowy bushes off to the side of the road and the kid running out from behind them are going to be very dark by comparison.

I’m not an expert in this specific topic (I’ve studied much more about color vision under well lit conditions), but several of the papers I skimmed when I started looking into it because I was frustrated about my street’s new LED lamps seemed to be funded by industry, and I’m not convinced that their experiments mirror real-world conditions of nighttime streets, or properly measure the effects of adaptation and glare.

The lighting industry wants to use a measure of luminous power based on “mesopic conditions” (i.e. mix of photopic + scotopic) because if they use the photopic function then blue light doesn’t really contribute much and their lamps don’t look as efficient or bright. My personal experience is that bright sources of blue light in my peripheral vision cause enough adaptation that I’m not convinced that a “mesopic” function as they’re using it is actually appropriate.

I should probably email some real color scientists to ask for clarification someday. If you know of a nice survey paper written by someone with industry-independent bona fides, I’d love to skim it.

Thanks. I haven't but I'll give it a try.

Thanks. I should take a look at those two books.
Personally, I like the diversity of ideas and implementations. It can lead to new explorations by researchers/developers, compilers detecting unforseen errors among other things, and immunity for a subset to untargeted malware.
"(...) Using data on site traffic and the proportion of users with ad blockers engaged, it argues that ad blocking initially increases traffic, but as ad revenues decline and sites are less inclined to invest in content, the pattern reverses and visitor numbers decline."
Aside from frameworks looking at it right might have to come from years of study which may necessarily not be easy but once you find something easy you are looking at it right.
Me, I'd rather emulate a few classic games. But it had me wondering for a while if I'd get any value from this, before deciding "no".

I find it interesting that so many of the people making YT videos and in the current Amiga community don't seem old enough to have been there first time around! So it can't be just nostalgia.

What I really want is someone to reimagine a 3000+ prototype[0] for this decade and a modern Intuition. Then I'd probably impulse spend a lot of $. Of course that would cost someone a lot of R&D spend! It's almost inconceivable anything could recapture the magic though. :)

There's an interview from a couple of years ago with the guy who made the X5000 https://www.youtube.com/watch?v=Mb6nbQSOAA0 and his Amiga addiction.

I started out doing real programming on an Amiga and I took a LONG time to retire it. Wasn't for lack of trying...

For years after if I needed to do something useful I used the Amiga over Win, on my first couple of very expensive PCs, because it was an order of magnitude more productive. It felt faster, with endless virtual screens, despite the ludicrous MHz/graphics gap. It was actually faster at most real world tasks except those needing raw CPU loads. It was far more reliable ripping or writing CDs etc. You generally plugged any Zorro card in and it just worked - none of the faffing with interrupt jumpers and Plug n Pray/BSOD. I used it over Linux/BSD as the sw wasn't there.

It took until the XP era, and much expense, before the Amiga became pointless. I was delighted when the Macbook Pro arrived... I'd sold the 4000 well before then.

I still miss many aspects of it. Not because I am somehow stuck in nostalgia for the 90s, MHz over GHz or scanlines and flicker fixers, but because I feel it was, in many ways a far better starting point for modern computing - mostly Intuition, but also the approach to everything in the hardware design (pre 4000 anyway). If only they had developed over the years since...

I suspect, had Commodore lasted, that they'd have gone an OSX-like route - new processor (this was already planned as there was no future in 68k series) and reimagining of Intuition on top of nix, maybe BSD. It already had a rather nix flavour, ARexx and so on. Hopefully on something more interesting than just PC clone hardware, though I doubt it these days.

Medhi Ali wanted to cut cost above all, and make some crap PCs, so the world got the piece of junk A4000 and AGA instead. Oh, and a cost-cutting A600 that cost more to produce than the A500.
I actually totally agree with you. Altium is the least-worst, but that's why I get so annoyed; I'm deliberately choosing to use it, but it's still such an unsatisfying experience.

+1 for this book. Abbey argued strongly and persuasively for the wilderness and raged against it disappearing, not just from existence with paved roads and air conditioned cabins but from our imaginations.
I probably made a poor word choice here. This particular person was a guy who could talk to anyone about anything. Literally. He had personal relationships with gas station attendants, political people, business people, etc. Ansolute magic.

He charmed his way past the various gatekeepers and got to the guy he was looking for. There was nothing deceitful about it.

I'm not sure if there's much of a market for it (I think it's shrinking), but fire lookouts are one job like this. I enjoyed reading Fire Season which is basically half history of the Forest Service & wildland firefighting and half a guy's personal account of being a fire lookout.
I think it might be a PR move and a lack of partner services on their part.

Bell is deep on Crave TV and stuff, Rogers killed their similar service just last year.

So they have a lot less to gain from the move and may get bad press for it... instead they'd rather get seen as the good guys.
Do you need PEGA Certification?
As a stay at home mom I recommend "Medical Coding" as a wonderful work from home option. Yes, you will need training. You can't just code medical records without having proper training. However, this is a real and promising career. I used to work for "Career Step" and they have an awesome Medical Coding course.

http://www.referral.careerstep.com/mc?ref=43233

Their training is done online and is self-paced. You could finish the program in 4 months but 6 months is probably more realistic. They do however give you up to a year to get it all done. Their program is approved by the American Health Information Management Association and the American Academy of Professional Coders. They work with companies such as CIOX Health, Lexicode, OS2-HCS, TrustHCS, Inovalon, Mckesson that hire their grads to work from home right out of the program.

The average salary for this career is about $40,000. Their entire program including books, instructors and job assistance is around $3,000 and they offer sweet payment plans.

Yes, a global perspective is important. That said, I think it's appropriate to regard Britain's going without coal for a day as an accomplishment. It shows that a country with a history of using coal can go without. Given your comment, this is something you care about. Do you see nothing positive in this submission?

Roofs aren't flat, aren't designed to support extra weight, and/or filled with antennas and HVAC equipment. If you want a building to have a helipad the architect usually has to plan for that from the start; retrofitting existing high rises would be extremely expensive. Plus upper floor occupants will complain about the noise.
I'm not aware of any good reasons, but I think GAAP standards say you can't recognize the revenue until the returns period ends? I think standard wisdom is to not have an official policy so as to keep the books simple (and maybe to avoid the downside I can't think of for returns periods) but use refunds pretty aggressively in support?

> The notion that shoppers will one day buy things simply with the push of a button or saying "Alexa, get me some paper towels" seems extremely far-fetched to me.

Indeed, that's not "one day". That's now. I've actually purchased paper towels using voice. I have a Dash and have also bought staples with the push of a button.

I don't see what's so far-fetched about this. It's pretty simple. When I'm buying a staple consumable product like paper towels, I am not shopping in the sense of looking around to compare products or pick the lowest price. I'm repeating a purchase that I've made before, at a price I'm already happy with.

I can also buy most of what I need online and have it delivered to my home. Traveling out to a store, shopping, checking out, and getting home often takes an hour or more, so shopping online saves me a lot of time.

Some people might be luddites, and that's their choice. The rest of us can benefit from this technology today.
I agree with almost everything. Talent and experience make a difference, but programmer productivity is situational. Some teams and projects bring out the best in everyone. And I've had bosses and customers and team members who make sure no one is very productive.

Working with legacy code is a skill too. I don't think it's true that a skilled programmer will necessarily be slowed down with a legacy codebase. Another way to look at legacy vs. green field is that with a legacy system there's already a fairly complete spec, expressed in the code. Learning to read and understand code is a skill that programmers can learn if they care to.
All depends on the nature of the work you're hiring for. The weakness I see with that approach is that I can't think of many workplaces where the main component of the job is solving 20-30 LOC algorithms.

The correct answer to most sorting algo challenges in the real world is some variation on "use Array.sort"

I'm more interested in how people interpret requirements, how they resource knowledge, how they architect their code, how they test it, etc.

My recently retired pet challenge was to fetch and amalgamate responses from three different, unreliable, URLs and then return them in a single JSON document. For the web developers I was hiring it worked well.
It's a social challenge that we still haven't worked out how to meet. Prior to the industrial revolution there were small rural communities, hamlets, villages, and towns, in places which grew up to be coal towns. But when the single economic driver disappears we don't know how to scale these communities back down.

I've always moved to where the work is, and I see the much same in my family tree all the way back to the industrial revolution (including mining engineers and mining machinery makers on my fathers side, who don't seem to have spent more than 10-20 years in any one coal field). But I know that many people are much more rooted in place. Forcing people to move isn't palatable in the U.K., but waiting for communities to disintegrate and people to move out on there own seems equally cruel
No matter how many IDEs I try I always come back to emacs. I am spoiled for life.
Closure Compiler already does this. Most JavaScript at Google is written with static types in JSDoc. Closure Compiler also has a DSL (sort of like template metaprogramming) where complicated generic type transitions can be defined with functional expressions.

It's really not. Weather is such a dynamic factor that if you went by forecasts alone or a wx briefer, you'd never be able to go. Computers can't also do preflight inspections where you physically inspect the condition of the aircraft, sump fuel, etc.
I think the ROI is underrepresented. There's a lot of maintenance and enhancement work available and less competition for it. I mostly work on retainer at rates equal to or higher than green fields developers. And my chances of success are much higher.

Not necessarily. Don't be fooled by the improvements in semiconductors and storage in the last decades: not everything doubles every 2 years. Battery specific energy seems to grow at around 5% per annum, doubling only every 14 years.
So I checked out that link and:

This may not be an absolute rule, but it seems like the best languages all evolved together with some application they were being used to write. C was written by people who needed it for systems programming. Lisp was developed partly to do symbolic differentiation, and McCarthy was so eager to get started that he was writing differentiation programs even in the first paper on Lisp, in 1960.

...but can that claim really be supported? Are c and lisp "the best" languages and if that "rule" is true, why does the claim have to be tempered for the two examples (C was written by people who needed to do programming at the time - was PHP not written for needs, too? lisp was only kind of developed for symbolic differentiation, and was lisp 1.6 one of the best languages or do we prefer scheme, common lisp...arc)?

He could have at least tried to make us believe it! :)
