  • A modern nuke is FAR from the “bang 2 rocks together” designs that were first designed. For a start, most are fusion devices. Fairly exotic reactions are used to make a small amount of fusion material to go critical. This creates a shaped charge on a fusion core. The compression wave sets fusion happening, which releases 95% of the energy. Most of Russia’s arsenal is of this sort.

    The downsides of these is the use of exotic elements. They often have a short half life, e.g. tritium, with 12.5 years. This means they decay. Even worse, some of the byproducts will actually poison the reaction. E.g. Rather than producing a flood of neutrons, they absorb them.

    If any of this chain fails, then your fusion nuke becomes, at best, a low yield fission nuke. More likely, it becomes a dirty bomb. It’s still nasty, but not the city destroying terror weapon it would be intended as.





  • Nukes and ICBMs are extremely complex devices. They also require extremely specialist servi e work to remain functional. Even worse, the only people who can actually check that work are the ones doing it.

    Russia hasn’t detonated a nuke in decades. I wouldn’t be surprised if most of their arsenal are now duds. The money embezzled, while boxes were ticked. Similarly, I wouldn’t be surprised if many of their ICBMs just wouldn’t launch.

    Russia’s nuclear capabilities are likely a paper tiger, and Putin likely knows this. Until they try and use them, they are scary. If they try and they fail, they are in a VERY bad situation.

    Putin is many things, but he’s not stupid. It would take a LOT more pressure from nato for him to even consider using nukes.


  • The message wouldn’t be to Putin directly. It would be to those both in his power base, or capable of disrupting it.

    The goal would be to push Russians to the point they deal with Putin internally, and/or put putin in a position where he needs to end the war to stabilise his own position. It’s all about making the right people feel the effects.

    Oh, and as a European, I think the risk is acceptable. If Putin struck at a NATO country, the results would likely be swift and short. The only unknown would be Russian nukes, and even those are far more of an unknown than most people think.




  • 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.








  • 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!

    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!
