  • Pay attention to how laye you generally are. I used to be chronically late. I began to notice I was generally about 20-30 minutes behind. I could often make up some of that, but it was rushed.

    The fix was quite simple, I trained myself to add 30 minutes “faffing time” to any estimate or leave time. I have an “aim to leave” and “MUST leave” time. I generally leave about 10-15 minutes ‘late’, but due to the buffer, I have 15-20 minutes leeway still to deal with things like extra traffic.




  • I tend to prefer pass phrases, they are a lot easier to type and speak, if required. Mine regularly blow past 20 characters.

    As for salting, that only defends against rainbow table attacks. The salt needs to be stored along with the hash. That is find for most accounts, but once you’re in banking territory, that’s a bad bet.

    You also can’t assume you have no vulnerabilities. If someone gets your database, you can’t defend against brute force attacks.

    Lastly, if you are doing passwords properly, you shouldn’t care much about length. There are a few dos attacks to worry about, but a 512 char limit will stop those, and not limit any sane password.



  • Repeating plastics tends to damage them on a chemical level. The polymer chains break and shorten. This ends with the plastic being more brittle. Since 3d printed parts have already been remelted once, they have even more degradation than injection moulded parts.

    I believe the recommended amount of recycled plastic is around 30% for PLA. Any more and the parts lose significant strength.

    I personally would prefer us to accept that plastics aren’t really recyclable. It’s better to move towards renewable plastics like PLA, and treat the waste as biomass (either composted or burnt for energy.



  • I work with radio camera links. The number of people who get upset over the receivers is depressing. They can make the 5G conspiracy theorists look educated.

    Receive equipment is incapable of radiating at all.

    The part that radiates is completely safe!

    Seriously, any danger would be at the camera end. I am happy to sit with it fully powered and the antenna between my legs. (It stops the camera getting knocked over). It can’t put out enough power to do any harm. It’s comparable to home WiFi and weak compared to the mobile phone you are happy to put to your head!



  • In short, no.

    The water needs to he hot enough to extract the optimal flavour from the tea fast enough. If you leave it longer, the bitter, oil based flavours start to come out excessively.

    This was actually a noted problem for Victorian (British) explorers. They couldn’t brew a proper cup of (black) tea up a mountain! I believe there were also patents issued, at the time, for tea brewing pressure vessels!

    Basically, you want the water as hot as possible, but not so hot it scolds the leaf. Black tea doesn’t scold (at normal water temperatures), so is brewed at 95°C+. Green tea scolds at around 80, so needs cooler water. White tea is even lower, again. By around 60°C your into stewing temperatures. You’ll get a lot more oils compared to flavour. You want to have your tea leaves out by this point.

    You also want to avoid agitating the leaves. Stiring, or squeezing the leaves tends to ruin the flavour. You know you’ve completely F’ed up a cup of tea if it has an oily scum floating on the top.

    Your best bet might be to use a laptop as the basis. They are already designed with power efficiency in mind, and you won’t need an external screen and keyboard for local problem solving.

    I would also consider having a raspberry pi 3 or similar as a companion. Services that must be up all the time run on the pi (e.g. network admin). The main computer only gets kicked out of sleep mode when required. The pi 3 needs less power than the newer pis, while still having enough computing power to not lag unless pushed hard.

    I definitely agree with SSDs. HDDs don’t do well when rotated when running. Boats are less than a stable platform.


  • In short, Facebook are incentivised to increase conflict and hate, it improves user engagement. They have also leveraged their large user base to boost numbers in threads significantly. Threads is already a cess pip of bigotry and hate.

    Federating with them would be like connecting your house’s drinking water pipe with the sewage pipe of an industrial pig farm. It would pollute our community to the point of destruction.

    They might try and control this initially. Unfortunately, it would almost certainly be part of an embrace, extend, extinguish attempt. ( https://en.m.wikipedia.org/wiki/Embrace,_extend,_and_extinguish ). They play nice till they have control of enough communities, then they stop the controls, to increase profits.


  • One of Sir Issac Newton’s famous phrases is

    “If I have seen further it is by standing on the shoulders of Giants”

    This sounds very nobal and humbling. However, its meaning totally changes with a few facts. It was written in an open letter to Robert Hooke. Hooke was apparently quite short, and EXTREMELY sensitive about this. Newton was basically dissing Hooke. Nobody will be standing on your shoulders, shortie!
