  • Are they cheaper? Even over 1M miles or whatever a truck engine is expected to go?

    Yes, significantly so. Hydrogen fuel cells have a much shorter lifespan and higher manufacturing/replacement cost than lithium ion batteries. The compressed gas tanks are also very expensive and have a limited lifespan (albeit a relatively long one, compared to the fuel cells).

    And as hydrogen scales up, it’ll get cheaper. It’s currently a bit more expensive than gas (about 3-4x), but that’s with hydrogen transported from some plant somewhere. If it’s locally generated from solar, it’ll probably be quite a bit cheaper.

    Market rate hydrogen is currently about as cheap as it’s possible to get, because it is almost exclusively from fossil fuel sources which are gradually winding down.

    Locally produced electrolysis hydrogen suffers from very low efficiency rates; about 2/3rds of the power used to produce the hydrogen is lost in the process. Assuming you don’t have an enormous overabundance of power being generated, it’s more efficient to store the power locally in batteries (which don’t have to be lithium ion if it’s for static storage; other chemistries become competitive if they don’t need to move around) than it is to store it as hydrogen. And if you’re generating a huge overabundance of power such that throwing 2/3rds of it away seems sensible, in most cases the question would be why you don’t make a grid connection and feed in anyway (extreme remote locations notwithstanding).

    They don’t use Reach; they are Reach. That’s the name of the company that owns them all (plus The Mirror, The Daily Express and The Star). That’s why they all have the same website.

    Most of the ones that aren’t Reach are Newsquest. Their website is also pretty terrible, but at least it doesn’t do that annoying swipe/scroll thing that Reach does.





  • where [it] comes from

    You imply it comes from:

    The “thin blue line” symbol has been used by the “Blue Lives Matter” movement, which emerged in 2014

    But you link to a Wikipedia article that says:

    New York police commissioner Richard Enright used the phrase in 1922. In the 1950s, Los Angeles Police Chief Bill Parker often used the term in speeches, and he also lent the phrase to the department-produced television show The Thin Blue Line. Parker used the term “thin blue line” to further reinforce the role of the LAPD. As Parker explained, the thin blue line, representing the LAPD, was the barrier between law and order and social and civil anarchy.

    The Oxford English Dictionary records its use in 1962 by The Sunday Times referring to police presence at an anti-nuclear demonstration. The phrase is also documented in a 1965 pamphlet by the Massachusetts government, referring to its state police force, and in even earlier police reports of the NYPD. By the early 1970s, the term had spread to police departments across the United States. Author and police officer Joseph Wambaugh helped to further popularize the phrase with his police novels throughout the 1970s and 1980s.

    The term was used for the title of Errol Morris’s 1988 documentary film The Thin Blue Line about the murder of the Dallas Police officer Robert W. Wood.

    I have no idea about this guy’s politics, but it’s a pretty well known phrase with a lot of different contexts.



  • Finished Perdido Street Station by China Miéville last night. I enjoyed it a lot, but it was one of the most relentlessly miserable books I’ve read in a long time. Bad things happen, continue to happen, segue into more bad things, and then the book ends. Looking forward to the sequel…after a sufficiently long break to recover.

    Just started Ancillary Sword by Anne Leckie. I enjoyed the first in the series (Ancillary Justice) and am hoping this one will manage to meet the same standards.

    Also picked up False Value by Ben Aaronovitch, to start when I finish Ancillary Sword. The Peter Grant series is something that I’d hesitate to say is good, as such, but they’re enjoyable and a much needed palate cleanser before tackling something punchier again.


  • Sorry, completely forgot to come back to this comment!

    I really enjoyed it, on the whole. The plot was tight and well paced, with a slightly languorous main plot intertwined and illuminated by a series of flashbacks. It does well with its central concepts (especially its core concept, the nature of individual identity and self for someone who exists as part of a larger entity), and has an interesting take on use of language (particularly the way it handles gender).

    The only real criticism is that in places the prose itself can be a little clunky, occasionally getting itself tangled up in messes of commas and subclauses for no good reason. But mostly the editing seems tight enough to avoid this becoming a major problem.

    I’d give it a 4/5 on my recommend-o-metre; enjoyable and worth the time (which, incidentally, isn’t very long as its a relatively short read), but not without qualifications.

    I’ve just started reading the sequel, after a few weeks break, so I’m hoping that’ll manage to keep to the same standards.


  • Only UK is known to have only moderate decline, but they probably think it’s independence for UK to buy Tesla, because fuck Europe for some reason???

    UK Tesla sales are starting from a much lower base. Sales in the UK were essentially half of what they were in Germany before the recent decline.

    BYD is now the largest EV brand by sales in the UK, ahead of Tesla. Whereas in Germany Tesla is still the leading manufacturer, even after the drop.

    Also, the UK EV market in general grew last year, whereas sales of EVs across all brands declined in Germany over the same period

    This is the way.

    Any big main meal is dinner, regardless of when you have it. A meal in the middle of the day is lunch, a meal at the end of the day is tea, a meal shortly before bed is supper. Any of them can be dinner too, but they don’t have to be.

    Breakfast is breakfast though. Dinner for breakfast is not an option.

    My Christmas dinner was on the table for about 1:30pm, and I didn’t start cooking it until 9am (with most of the actual work not starting until more like 10:30). I did a little prep the night before, but not much really.

    It’s not really that much work when you’ve got it down. It’s just a roast. If you can get it on the table for lunch time most Sundays, it’s not that big a deal to do it on Christmas day.


  • I reckon it’s simpler than that. Zuckerberg has never really invented anything novel; Facebook was a straight clone of a whole bunch of competing social media sites (which just so happened to win the numbers war), and WhatsApp and Instagram were both acquisitions.

    I think the Metaverse was Zuckerberg trying to prove to himself and others that he and he personally could come up with the “next big thing”. The fact that he came up with something which absolutely no-one wanted (and most people barely understood) is a testament to why he never came up with anything ground breaking before, too.


  • Ads and monetization have ruined the internet compared to what it was. Early Internet was completely without ads, and things were run by people who were actually interested in the content presented, not in profits.

    How early are we talking here? If you mean pre-Web, in the Usenet era it was standard practice to pay a subscription to join a Usenet server. If you mean the early Web, ads were already everywhere by the mid-90s.

    There is (currently) only one living version of the Mastodon code base. It could be forked in the future, but it hasn’t been.

    There are other ActivityPub microblogging platforms (Friendica, Mbin, Pleroma, Threads if you count it) which users could also be running, and from the point of view of users it shouldn’t be obvious what any other given user you interact with is using, but that’s not got anything to do with Mastodon pull requests.

    If in doubt, you can always play the old “Chosen One” card to hand waive that sort of thing away.

    Mr “highest midichlorian count in history” Skywalker might get a free pass just because he’s magic.

    Which on balance probably means it was pretty lucky he did a redemption arc before he died, otherwise they’d have been stuck with an evil maniac in their immortal ghost club.



  • I hosted a meeting with about a dozen attendees recently, and one attendee silently joined with an AI note taking bot and immediately went AFK.

    It was in about 5 minutes before we clocked it and then kicked it out. It automatically circulated its notes. Amusingly, 95% of them were “is that a chat bot?” “Steve, are you actually on this meeting?” “I’m going to kick Steve out in a minute if nobody can get him to answer”, etc. But even with that level of asinine, low impact chat, it still managed to garble them to the point of barely legible.

    Also: what a dick move.


  • That’s a really interesting read (and worth much more attention than the pithy one-liners of people who just want to read the title).

    On reflection, I think my take away is that Bluesky will always by necessity of its design be hosted and controlled by a single centralised company. But what their architectural model does allow is the possibility of a wholesale migration from one centralised provider to another. That is, it would be possible for a suitably resourced and motivated company to host its own mirror Relay and other components and have essentially a fully functional Bluesky clone. In the event that Bluesky ever “does a Twitter” and go into terminal decline, in theory this might mean that a successor/competitor could emerge and take on the network without loss of existing content.

    I’m not sure that’ll ever actually happen, but it’s an interesting thought.
