  • I don’t think modern Raspberry pi’s make much sense unless you are using GPIOs or really need the low power consumption. The 3 and the 4 were OK price wise but the pi 5 is quite close to all these N100 mini computers and they are a lot more performance and expansion compared to a raspberry pi 5 and still quite low power.

    Either a Topton or similar N100 based machine or a mini PC second hand is the way to go at the ~$100 mark. The mini PC will be faster and probably more expandable and cheaper but also more power consumption.



  • Late last year they were talking about $40 for a KWH which compared very favourably to LifePO4 that was more like $130 at the time and Li-ion that was more like $200. However right now on alibaba you can get a 200Ah battery for about $60 and the LifePO4 300Ah are now down in the $50 range which is an incredible drop in the space of 6 months. So in practice they are less dense and more expensive but I think its new technology introduction pricing and at some point it should be about a third cheaper than LifePO4 for the same capacity, all be it a bit bigger and heavier and quite considerably cheaper than Li-ion for the same capacity.

    The small 18650 and other small sized cells have started appearing on aliexpress as well so its possible to get those too butt they are a lot more expensive than a basic Li-ion 18650 at the moment for a lot less capacity. I think its mostly the bigger cells that most people interested in Sodium Ion will be wanting (home battery and grid storage solutions and some of the low/mid range cars) more than small cells since typically the smaller stuff you want to maximise capacity even if it costs a bit more and most will want li-ion and ideally the newer nearly solid state li-ion that doubles capacity per KG.



  • These early days of processors I was constantly upgrading between the companies. A Pentium to K6 to a PIII celeron to a Duron and then an Athlon XP and then a Pentium HT before finally the stable era arrived with the Core 2 duo and all the subsequent CPUs largely being small incremental upgrades at more or less the same clockspeed peak and lots of the performance coming from more cores. There was a lot of back and forth in price/performance and absolute performance as various innovations and pipline length increases and clockspeed were release. Things changed drastically in the 8 years we went from 100Mhz Pentiums through to the Core 2 Duos where both companies lead and trailed and you needed to upgrade your machine most years to keep up with modern games.







  • Its a pretty reasonable argument. The entire point of human rights is that states can’t break them and they are risking the lives of billions with every bit of increase in CO2 they allow to occur. Given they have signed up to treaties to not do so and are still carrying on suggests that they are performative in saying they will act while not doing so. The crack downs on protests around climate change have been shameful but I guess after 4 decades of inaction politicians just don’t want to hear people screaming at them since they never intend to act.



  • When they are reading out the results they do say how many spoiled ballots there were, the problem is the BBC et el usually cut off just as that is being read and they don’t count it across the country or keep the results and as the results start coming in faster you don’t hear it. The spoiled ballots doesn’t seem to make it into any of the official stats for an election that I can see. So unfortunately its one of those acts that ought to be better than not voting but in practice turns out to be basically the same.

    I certainly wont be voting for the Conservatives or Labour but as far as protests go I am better off voting for another party that wont win as a protest than spoiling the ballot as it will be more visible and included in all the stats.


  • People don’t realise how common this is in our society unless you are a minority. Its everywhere. The state abuses disabled people via the DWP, the doctors do the same to disabled people by refusing to treat or put secretly DNRs on their records. Access is awful everywhere and people with wheelchairs fail to get on buses because the spot is taken by a pram which its not allowed to be used for, then there is the removal of accessible bridges for the train network replaced with ones that aren’t accessible, the lifts barely work when they are installed. Then there is all the attacks and verbal abuse on the streets from random people and so much more besides. Its everywhere in every place a minority would go.

    Despite whatever self reported level of discrimination the UK gets as one of the best in the world any minority in this country can tell you how many times a day they are abused by someone else. Its every single day. The Police, NHS and other state functions all do it and there are no consequences for any of it. It is so common infact its not news and rarely makes the news, this one is odd for making it into the press because this happens in schools across the country every year and it certainly happened at my school photos.

    It is hard to accept this basic reality as someone who isn’t a constant victim of our society but if you listen to the people who are the victims of this stuff its relentless.





  • This is almost certainly Covid. We already know it damages the brain and attacks the executive as well as behavioural centres of the brain and children are out sick for twice as long from school directly due to sickness. We are also busy trying to force children with Long Covid, of which there are 68,000 in the UK now, into school and unfortunately that will make them very unwell. Most schools are having to use a lot of substitute teachers due to doubling of sickness and teachers are the second hardest hit profession with Long Covid (behind medical staff).

    It will keep getting worse as more and more suffer from Long Covid impacts.




  • I have used Bitcoin a number of times for international purchases. Its not really got to the point of currency so much as a medium mostly of speculation and often interchange for crime but it can improve your privacy. The user experience of the payments isn’t the best but international transfers are often hard to do anyway and in that particular field it can often be a lot quicker, cheaper and easier.
