I heard of him as Computer Science in TCD awards - or used to award - a prize for the best 4th year project called the Ludgate prize. The problem is that he left no written body of work. I recall reading of a researcher who contacted his su

Regarding affordability, if this battery can achieve 30,000 recharge cycles vs 500 for li-ion, then relatively small differences in materials cost will be irrelevant, no? Particularly if used for grid storage.

The last peat burning plant shut down two years ago[1]. Industrial peat harvesting has ceased. A limited amount of peat harvesting is allowed but just at traditional/family/domestic scales. [1] https://en.wikipedia.or

I can't view that graph. German wholesale prices are pretty much bang in the middle of European average which is what you'd expect given the high level of integration between each country's domestic market and the large amoun

And? I don't get the reliance of this at all? I'm responding to the suggestion that Germany doctored the numbers regarding manufacturing output. I found this suggestion weird but I've tried to respond with a straight answer

This is such a common use-case or way of working (write down the melody/harmony first, then fix up the timing) and such a natural way to transcribe music, that it gets requested all the time. The weird thing is that the software can do

Ireland has 7.5m head of cattle[1] - I think that qualifies as a "large amount". And you can add 6m head of sheep and over 1.5m pigs. About 40% of Ireland's CO2 equivalent comes from agriculture/agri-business. [1] htt

The former. "Manufacturing output" is a standard statistic, like GDP, used for global comparison and historical comparison so how it's measured is defined by the OECD.

What? Germany is a net exporter of electricity[1] - this was in 2022 and the trend is that net exports will increase this year. France (65% nuclear) imports more electricity from Germany than it exports to Germany. I don't understand

German manufacturing output is 90% higher than it was 20 years ago. Your worldview is seriously askew.

It's a MIDI[1] synthesiser. You need to attach it to an external keyboard or sequencer to get any sound out of it. Think of it as analogous to network attached computer - on its own and disconnected, it's not going to do anythin

"The largest drop in life expectancy in recorded history"? Life expectancy dropped by 2.56 years between 1990 and 1999 in Russia. Not great but not even close to being historically significant. Life expectancy in the USA dropped

You're talking about Xlinks? They are nowhere near doing it. They have been talking about it since 2018 and trying to get investors to give them money but despite favourable press and interest from politicians, a heavyweight board, n

Yes - all the serious proposals are dead (the xlinks guy is a grifter) because underwater HDVC costs have risen while panel prices are a tenth of what they were. Not only the finances, but (as I described in another comment), the security a

In general, yes, more interconnection and better transmission can only be good. But in the specific example I gave, the finances just don't work. Underwater HDVC is just too expensive and panels are too cheap - even with the value of

Putting solar panels on roofs doesn't make a lot of sense to me. Per kWh, rooftop domestic PV costs can be unto 10 times more expensive on a levelized cost basis ( https://www.lazard.com/media/2ozoovyg/lazards

Some reasons that spring to mind: - Compile speed - Kotlin is still painfully slow - about 4-5 times slower than equivalent Java functionality (rough estimate) - Kotlin is completely proprietary, no community or openness, no alternative to

I dunno, the fact that integers are by (often mutable) references has to make it really difficult for optimization. You don't have to be "sneaky" for this to bite you with Python. Maybe it looks obvious when stated in a bare-

I don’t think so - I’ve written parsers using flex/lex yacc/bison, antlr, a bunch of functional combinator libraries and maybe others I’ve forgotten but now would never consider anything except hand-written recursive descent with

Moving work/commits from one local clone to another is something I do regularly - just using vanilla git push/fetch. I’ll grant that saving disk space is a concern for many - not for me - the largest repo I use is 2-3 million LOC

What is the advantage of worktrees over multiple clones? Using multiple clones is trivial - there are no new git concepts to learn - and works perfectly with all build tools particularly ones that heavily use caching. What productivity im

Yeah I don’t get it - without search dominance google’s entire business model is highly vulnerable. Why have they allowed search quality to stagnate while pouring billions into random tech areas where they have little competitive advantage

I force myself to be careful to use the word cynicism instead of skepticism - the former word describes an a malevolent intention while the latter does not. I do this as an exercise as it’s been too easy for me (I’ve a skeptical nature - a

The article doesn't spend enough time on the fact that actual _interoperability_ didn't actually come to CORBA until it was already past its peak. So a key feature of the technology never really worked. I worked at a CORBA vende

I second this recommendation. I found it surprising easy to read - the sardonic humor kept me going even when I struggled to keep track of all the details/people/names/places. Although I didn't attempt the full set - j

Have you specific examples? The biggest failures associated with the last nuclear “Renaissance” were project/budget failures - e.g. https://en.m.wikipedia.org/wiki/Nukegate_scandal - same in Europe where the “new

It’s not consistent but I would estimate that “0” buttons are as common as “G” buttons in elevators in Europe - along with -1, -2, etc for basement levels.
