No, I agree, but you specifically mentioned "science-fiction" in the second post, and implicitly denied even their existence in the first post. I think there's a reasonable distance between that, and economic considerations / the fact that test hardware has yet to exist that's presented in those papers.

The Be would be inside the (radioactive) reactor vessel, which already has extremely strict isolation requirements. I believe it's accessed and maintained with robotics.

As for the change, I'm just an interested amateur, so shouldn't go into details and please take this with a big grain of salt, but I've heard it was a result of proposed scenario(s) that some do not regard as realistic.

> you would need 100% efficiency to be able to breed your own tritium

How so? As I understand it, the breeding reaction is exothermic (Li-6 + n -> He-4 + T) so all you need are neutrons, for which (as someone pointed out to me two years ago[1]) neutron multipliers would be used.

Three years in, and it's working great. We're different people with different work styles, but get the job done with tons of respect on both sides. The only difference is that the friendship is perhaps at a sightly further remove than it used to be.

People said it might go badly; they said the same about living with a different colleague, and that also went perfectly for me.

Emphasis not just in the narrow sense of showing intense emotion, but rather the general concept of giving a sentence rhythm and prosody, often to highlight a wry or ironic situation. Your analysis is correct that GP likely did not do it entirely to invite readers to get annoyed on their behalf, but rather to humourously focus on the contrast between the arduity of setting up and waiting for a dual-boot on one hand, and playing a "f*cking game" on the other.

> There are many better ways of calling attention

Written expression is a form of art, not a formula with a correct answer.

It is a stylistic device that serves as a sort of emphasis. Rhetorically censoring all or part calls attention to it as profanity.

You hear an analogous effect used a lot in spoken speech (definitely in the UK, not sure about USA), for example, "ff-<beat>-in' thing". This stresses it in a way, similar to varying tone or volume, that would be missed in a flat reading.

Are you thinking just of roundabouts that include a raised middle and/or central reservations on approaching roads? In general, roundabouts need no more space and cost than a regular road would, see e.g. https://goo.gl/maps/Y6jzLq5SuYzMMf2a6

These questions are tackled in most basic primers that should show up in a google search such as you suggest. E.g.:

> Climate is always changing. Why is climate change of concern now?

> All major climate changes, including natural ones, are disruptive. Past climate changes led to extinction of many species, population migrations, and pronounced changes in the land surface and ocean circulation. The speed of the current climate change is faster than most of the past events, making it more difficult for human societies and the natural world to adapt.

> Why be concerned about a degree or two change in the average global temperature?

> A degree or two change in average global temperature might not sound like much to worry about, but relatively small changes in the earth’s average temperature can mean big changes in local and regional climate, creating risks to public health and safety, water resources, agriculture, infrastructure, and ecosystems. Among the many examples cited by the 2018 National Climate Assessment are an increase in heat waves and days with temperatures above 90°F; more extreme weather events such as storms, droughts, and floods; and a projected sea level rise of 1 to 4 feet by the end of this century, which could put certain areas of the country underwater.

I dimly remember trying this five years ago and it being a bit of a mess. IIRC it was that date picker widgets in browsers presented in a different format to what the Accept-Language header suggests (a killer when you're trying to render static and editable dates in the same table), or users were confused seeing dates in their preferred format after being linked from a site that disregards them, etc. Perhaps the situation has improved by now.

As someone that enjoys trying to make up inversions on the spot, and laments that chord charts only ever seem to acknowledge open chords and E/A-shape barres, that command line tool looks fantastic. Is it available to download anywhere?

(P.S. I can't work out the tuning in the score you posted, but it looks like another user posting above[1] made a tool that provides a fingering -> chord name solver?)

There's a great and very comprehensive chart by "Our World in Data" about the breakdown of emissions / environmental impact for different foods:

https://ourworldindata.org/uploads/2020/02/Environmental-imp...

As you can see, it specifically points out that the transport aspect pales across the board in comparison with other more important factors.

These are all excellent points—thank you for clarifying some of the parts I hadn't considered. In terms of the last and how practical it is, we're more-or-less saying the same thing; my hope was to be clear on what is a result of a tough engineering dilemma, as opposed to impossible or intrinsic, just so casual readers of this thread don't go away with the wrong idea.

> you will always need at least a small fission reactor to breed some tritium

The idea for future designs is to breed Tritium in the blanket surrounding the vessel. This obviates the need for external sources.

> everything close to the reactor becomes brittle in 2-4 years

I'm no expert on solid state physics, but that seems a little short? JET is more than ten times as old, and as we speak it's in its second run of D-T experiments.

> These are all intrinsic limitations of fusion that fission reactors just don't have

To be clear these are limitations of a specific kinds of fusion reaction and/or reactor design, primarily that of Deuterium-Tritium in a solid-walled tokamak. This may be a nitpick as it's currently far and away the most promising for energy production, and the alternatives are much further from any sort of workable prototype, but I have heard of them undergoing active research: tri-alpha (aneutronic reaction, meaning no activation or embrittlement of reactor components), liquid metal for the walls and divertor (in effect, continuously replacing neutron-bombarded material), etc.

Personal anecdote, but since Ogham has been available in Unicode, I've seen the odd person start being interested in it to write out names, exclamations, etc. It feels like a small previously-closed gate has been opened for a nice little way for people to connect and engage with an old part of our culture.

Just a note that you've framed the question as "without JS turned on" but it's not always a choice; there are people who don't have access to sufficiently new hardware or reliable telecoms that it will work as intended.

As an example, for the past ten years I have had to browse with a tablet that crashed every time JS was enabled (luckily I could recently justify the expense of a new one, so that won't be the case any more when it arrives)
