  • Commented on Empire Games (and Merchant Princes): the inevitable spoiler thread!
    Correction - 24 nanoseconds tick-to-trade mid-2020. Trading in 24.2 Billionths of a Second (Medium, Schweitzer Scott, Jun 1, 2020)...
  • Commented on Empire Games (and Merchant Princes): the inevitable spoiler thread!
    A phrase to look for is "latency equalization": Cboe/Equinix Latency Equalization Infrastructure provides an equal optical length of fiber to customers connecting in either the NY4 or NY5 Secaucus, NJ datacenters. I once watched a demonstration of a readout of...
  • Commented on Empire Games (and Merchant Princes): the inevitable spoiler thread!
    Thanks for last night's pointers and notes; appreciated. (Note I use a real name here.) Not my country, (and seems to have been a decent man; looked at a skim of history and some parliament transcripts) but re "Brass Eye...
  • Commented on Empire Games (and Merchant Princes): the inevitable spoiler thread!
    - The China/Hong Kong material is about interesting political shifts in China (including HK) threatening some wealthy people both directly and indirectly. (Aside: China's plans to increase coal usage are not a good look.[1]) - The "Shout out to the...
  • Commented on Fossil fuels are dead (and here's why)
    Interesting analysis of the potentials for persistence of some pandemic-caused human behavioral changes to lead to (cause) decreases in the difficulties of global heating mitigation: Climate mitigation scenarios with persistent COVID-19-related energy demand changes (Jarmo S. Kikstra et al, Nature...
  • Commented on Empire Games (and Merchant Princes): the inevitable spoiler thread!
    phys.org is a good feed, and has some useful subcategories. I too let my New Scientist subscription lapse due to the vile nature of the purchaser. (A 20+ year subscription; sort of hurt, but New Scientist has always been a...
  • Commented on Empire Games (and Merchant Princes): the inevitable spoiler thread!
    Consider a sperm race: Why so many sperm cells? (2015, K. Reynaud, Z. Schuss, N. Rouach, D. Holcman) [1] A key limiting step in fertility is the search for the oocyte by spermatozoa. Initially, there are tens of millions of...
  • Commented on Invisible Sun: Themes and Nightmares
    I replaced my iPhone 4 with the original iPhone SE, because it was the same shirt-pocket size, and has a headphone jack. It still works; not sure how long iOS updates will continue. Will replace with a newer SE when...
  • Commented on Empire Games (and Merchant Princes): the inevitable spoiler thread!
    - The new-model world-walkers don't get headaches from world-walking. That suggests that the USA biotech is unusually sophisticated, even in that timeline's 2020, or that they got lucky in their engineering, or that the prions weren't in that majority subset...
  • Commented on Invisible Sun: signed copies and author events
    Enjoyed it a lot. Looking forward to the spoiler thread. (I wonder if Greg T will spot an almost direct quote (perhaps coincidental) near the end of the novel, related to an alleged Richard Courant quote about lack of sanity.)...

    Dune: "The Sleeper Has Awakened" scene. Re-read the relevant section of Dune, which was compressed into that line in the David Lynch movie adaptation. You've been a teacher. Some of the most useful advice was maybe in straightforward comments at...
  • Commented on Invisible Sun: Themes and Nightmares
    Decent attempt at a taxonomy (with 8 categories) of anti-vaxxers: Varieties of anti-vaxxer (Paul Campos, September 26, 2021, Lawyers, Guns & Money) US-focused, but generally useful with the possible exception of the "political tribal identity" category (depending on country)....
  • Commented on Fossil fuels are dead (and here's why)
    I've been holding that one in reserve for when somebody gets too annoying about how solar power won't work in the UK. There's also the issue that the mirrors could be pointed (by malicious actors) at places that don't want...

    malus domesticus You have a very good eye. Re one of the puns, my mother showed my brother, sister and I the washing machine and detergent when we were in our early teens. There was probably some instruction about color...
  • Commented on Invisible Sun: Themes and Nightmares
    there are a number of skeptical views out there about this paper, It's a very long paper with a lot of lines of evidence. The first author (Ted E. Bunch) has published some similar papers over the years. (I don't...

    Apropos of nothing, what do all y'all think of the prototype US Space Force Dress Blacks? Makes me happy. Not a bad look. I will laugh if I ever see one F2F, though....

    Related, China (Xi) is making some moves. We'll see how real they are (but it looks good). China's own coal usage is still horrifying though.[1] (The charts in that ourworldindata.org piece are stark.) Bolstering Confidence and Jointly Overcoming Difficulties To...
  • Commented on Fossil fuels are dead (and here's why)
    Interesting, thanks. Seriously needs an update that includes 2020, and the GHG emissions changes (most but not all temporary) caused by the worldwide pandemic response. (The causality was often complicated.)...

    Dosage is one substantive difference between the Moderna and BioNTech/Pfizer vaccines: "Each dose of Pfizer’s contains 30 micrograms of vaccine. Moderna went with a much larger dose of vaccine, 100 micrograms. " The (including human) immune system is still not...

    Rubbing out Question Marks #216: Sorry about mentioning your nym upthread. I was pinging, concerned about your well-being. A few threads ago: "Oooooh. Careful, us Djinn know our crab-apples." I am amused. The tree that the nursery labeled a crab-apple...

    Another factor: security clearances are said to be easier for members of the LDS Church to acquire. https://www.atlasobscura.com/articles/why-mormons-make-great-fbi-recruits The disproportionate number of Mormons is usually chalked up to three factors: Mormon people often have strong foreign language skills, from missions...

    But what if the losing side says "back down or we nuke you"? Answer: you either back down or you nuke them first. China is currently building a few new fields of missile silos (open source intelligence, has been in...

    I had to read the Bascule bits at about one half(third) speed but had little trouble with them other than speed. Remember the scramblers that would randomly mix the inner letters of words (i.e those 4+ characters long)? Here's one:...
  • Commented on Fossil fuels are dead (and here's why)
    That semantic scholar page has two links. One is free (the font is horrible, though, at least in my browser.). Often also good to search scholar.google.com for the title, and then show all versions; some may have a link. Also,...

    KSR must be a contender. Recently finished his most recent, Ministry for the Future, and it's determinedly optimistic. Yes, even including entities/orgs like the “Children of Kali”. The approach to globally encouraging carbon sequestration was also sort of interesting. (Not...

    The vox pieced linked above, Trevayne #812, is pretty readable and detailed. Here's the full link: Geothermal energy is poised for a big breakout - “An engineering problem that, when solved, solves energy.” (David Roberts@drvolts Oct 21, 2020)...
  • Commented on Invisible Sun: Themes and Nightmares
    Hadn't pre-ordered the e-book yet, so done, and looking forward to it. This The Prodigy song (linked by SotMNs a few times) is ambiguous enough that I'm hoping it will (also) be mapable to the novel. The Prodigy - Invisible...

    As Pigeon says, a serviceable single lens "microscope" good for up to about 60x can be made with a water drop. The easiest is a small round wire loop (e.g. formed around a nail), though anything non-porous and thin with...

    It sort of reminds me of silver vs. copper for electrical conductors. Well, some audiophiles might disagree about the virtues of silver: Also with your cable more life and energy and actually more fun. Who could argue with "more fun"?...
  • Commented on Fossil fuels are dead (and here's why)
    That Vox piece on geothermal energy is surprisingly technical/detailed. For UK people, https://en.wikipedia.org/wiki/Geothermal_power_in_the_United_Kingdom (Worth a skim, but TL;DR district heating is plausible. e.g. https://www.engie.co.uk/energy/district-energy/southampton/ )...
