  • Sodium Ion battery cells (From the article):

    • Energy Density: 145Wh/kg (How much Weight)
    • Energy Desnity: ??? (How much Volume)
    • Life cycle: 1,500 charges (Normal temperatures)
    • 92% capacity at -20°C

    Lithium Polymer (From Harding Energy - https://www.hardingenergy.com/lithium-2/ - assuming this is representative)

    • Energy Density: 100 - 158Wh/kg (How much Weight)
    • Energy Density: 185 - 220Wh/l (How much Volume/Size)
    • Life Cycle: ~500 (No temperature comments)
    • Operable Temperature: -20°C - 50°C

    That feels to me like the reported characteristics are on-par or better. Whether the real-world characteristics are the same, and if they really last as long is an open question.

    I’d love to find out the Wh/l - i.e. how much physical size is needed to store the same weight of battery. It’s not such an issue with the likes of an e-bike, or even so much a car, as there’s spaces to shove it, but in something like a phone (Especially when people are so fixated on ‘super slim devices’ to the detriment of all else), if it’s 2 or 3 times larger physically, I can see it not catching on in those areas.

    Searching on the Wh/l for Sodium batteries, I found nothing that seemed authoritative.


  • I’ve been using an Ikea Markus for about 15 years, which I’ve been really comfortable with and is not super expensive. It’s not massively adjustable, so if it doesn’t fit your body shape, it might not be for you; but at the same time, it’s fit me and works really well and has enough adjustment that I’ve been able to shift through quite a few different changes in my life over that time. The ‘pleather’ is flaking now, and the padding has completely collapsed, but I’m looking to replace with another one of the same because it’s been good to me, which is probably the highest rating I can give something… it’s worn out from massive amounts of use, and is now due for replacement with exactly the same product.


  • I started developing websites in the mid-90’s, and shipped my first commercial one in '99. I didn’t really have JavaScript (As we know it today) - it was a fancy client-side ‘make-funky-things-happen’ enabler, not a ‘make-the-whole-page-work’ enabler. I’ve always looked at frameworks as something that’s useful to solve specific problems - Google Mail couldn’t be made without a framework. A web forum? It might help. A regular website? Doesn’t need it.

    You don’t need an SPA to render any of the marketing, sales or other websites. Most webshops don’t need an SPA, just some light basket handling and data rendering and caching. But say that to any modern web dev, and you’re looked at as though you’ve got three heads, while they ship a page that’s multiple megabytes of JS to layout some text and prettify some pictures.





  • It’s exactly the same gravitational pull as the star that previously collapsed… (And I’ve not read the article (yet), this is just a personal nitpick that I’ve had for a LONG time).

    –edit after reading the article–

    In terms of inevitably falling into a black hole, it’s only the material that formed interior to three times the event horizon radius — interior to what’s known as the innermost stable circular orbit (ISCO) in general relativity — that would inexorably get sucked into it. Compared to what actually falls into the event horizon in our physical reality, the purported “sucking” effects are nowhere to be found. In the end, we have only the force of gravity, and the curved spacetime that would result from the presence of these masses, affecting the evolution of objects located in space at all. The idea that black holes suck anything in is arguably the biggest myth about black holes of all. They grow due to gravitation, and nothing more. In this Universe, that’s more than enough to account for all the phenomena we observe.

    That summary explains it better than I can.

    I got screwed over with the motherboard, as it had to go back because of bimetallic contracts in the SATA ports that could wear out and stop it working so there was a big recall of all the boards… Was an amazing system though and if I hadn’t seen the computer I’m currently running for an absolute steal, I’d probably still be running it with a 3060 as a pretty potent machine still.

    Of course, then I’d never have the experience of just HOW FAST NVME IS! :⁠-⁠D

    I had an i5-2500k from when they came out (I think 2011? Around that era) until 2020 - overclocked to 4.5Ghz, ran solid the whole time. Upgraded graphics card, drives, memory, etc. but that was incremental as needed. Now on an i7-10700k. The other PC has been sat on the side and may become my daughters or wife’s at some point.

    Get what you need, and incremental upgrades work.

    After the turn of the century,
    In the clear blue skies over Germany,
    Came a roar and a thunder men had never heard, Like the screamin’ sound of a big war bird…

    Up in the sky, a man in a plane,
    Baron von Richtofen was his name,
    Eighty men tried, and eighty men died,
    Now, they’re buried together on the country side…

    In the nick of time, a hero arose,
    A funny lookin’ dog with a big black nose,
    He flew in to the sky to seek revenge,
    But the Baron shot him down…
