I barely got through the introduction before giving up. The opening line - "Hydrogen is the ultimate clean energy." - is a vague, meaningless, scientifically vacuous claim. I'm not sure that hydrogen can even be considered &q

The visible remains of ring forts in Ireland are commonly referred as “fairy forts”. In many areas of the country there is a taboo associated with interfering with or disturbing them.

Really? This must be a very recent change. If your teacher asked you "An dTuigeann Tú?" ("do you understand?"), they would accept "Níl" as an answer? It sounds horribly off to me.

Only if you assume everyone is sitting around doing nothing waiting for window repair work to arrive. More likely is that the effort and resources required to fix the windows will displace other economic activity which would have contribut

Thanks for the thought-provoking article. I think I agree with the conclusions even if the analogy isn't perfect. The connotations of under-utilization or over-provision are often negative - particularly in management - but I think a

This queue analogy doesn't quite reflect the behavior of queues of development tasks versus queues of customers waiting to get a Bagel. The Bagel queue is strictly FIFO - while work queues generally operate more like a priority queue.

I've seen it used in an old code base so that a specialized Map implementation could be used with String keys. I'm not even sure of the name of the library it came from or what it was called - maybe "ObjectHashMap" or so

The US has also gained immense power through growth in other sectors like finance/banking/insurance - the biggest sector in terms of US GDP. The second biggest sector - professional/business services - also allows the US to

I don't think using IBM is an appropriate comparison. It is a company in actual decline - revenues peaked at about $110B just over ten years ago and were less than $60B last year. Like I said US manufacturing output is growing and has

US manufacturing output has not actually declined though - it has never been higher and has increased over 40% in the last 2 decades[1]. The perception of US manufacturing decline is widespread. My guess is that this perception is due to a

I don't see hydrogen playing any role for energy storage or grid demand balancing. Even if all the technical and engineering challenges associated with storing and transporting it safely could be addressed, I just don't see how th

I don't think this applies in this case. The brackets here are used for resolving precedence only. They are a syntactic feature which are not represented in the language semantics. Where brackets are used in some languages to construc

I don’t get you? I’m not asking you to provide evidence that “places exist where moving fiat across borders is practically impossible“. I’m interested in the many poor people you know who have been lifted into middle class through being pa

That’s not particularly convincing. If I can find the information by searching as you recommend, then the information is already out there so you wouldn’t be revealing secrets by providing the detail or a link to the relevant search results

Could you provide a bit of detail? Like giving some examples of companies that pay their employees in bitcoin? I'm somewhat sceptical as I know someone who works for a company in a role organising payment to employees in poorer and th

The electricity from small modular reactors is far more expensive than that from large reactors - about twice as expensive by some estimates[1]. They also produce more waste per MWh generated. The industry has been pushing in the opposite

Burning gas on a stove to heat food is about 40% efficient. Induction is about 85% efficient. Modern CCGT is about 60% efficient. So converting the energy contained in natural gas into electricity in a large CCGT plant and then cooking w

Yeah, I've used a bunch of non-blocking paradigms over the years and all become painful quickly once the system becomes non-trivial, except for green threads. I was very disappointed that Rust dropped this feature in favour of async.

The nuclear industry is dying on aggregate globally, as indicated by metrics such as market share, overall capacity or price competitiveness. Nuclear proponents often blame the cost of meeting onerous (and by implication unreasonable) regu

The industry lobbies heavily (as described in the article and well documented in other sources) for subsidies not reduced regulation. This suggests the nuclear industry's issues are financial not regulatory. This conclusion would als

Imagine you were given the choice before he opens any boxes. “Stick with your pick“ or “Switch to picking all 99 of the others”. Opening non-prize boxes before showing the contents of the last box is just part of the reveal drama - whether

You're actually being given the choice between "my initial pick contains the prize" or "the prize is contained in any of the other 99 boxes". Okay - the host does a routine to add to the "drama" by reveal

There was a C library - posted here but I cannot remember the name - which used the preprocessor to avoid invoking a function call per comparison. You'd use it something like this: #define SORT_ELEMENT_TYPE int #define SORT_COMPARE(a,

I'd love if they improved navigation while in Street View. It works okay when the geometry is simple - like on a long road/street with no junctions. But in more geometrically complex areas - for example, in urban settings around

"between 0.6 and 1.3 million tons of sugar" doesn't sound like a lot? Humankind is adding 35 BILLION tonnes of carbon dioxide per year.

This is a striking example of what I've observed in many places which has often made me wonder why the intersection between nuclear advocacy and some form of climate change denialism is so large? The inconsistency is odd: "I pass

I would argue that the claim that "No one knows the origin of Ulster’s ‘Red Hand’" is somewhat inaccurate. The wikipedia page[1] covers a lot of its history. Because it's very old, dating back to at least the European dark a

Yes, you can achieve also reduce local readability by passing objects containing buckets of state around. But such classes always smell to me - particularly if component instances have other aliases. But I try to avoid it by designing dis
