  • I believe that was a strike at their centrifuges. They are needed to enrich uranium to powerplant grade or weapons grade.

    Iran had agreed to stop using them, as part of the treaty trump tore up. Afterwards, the lack of any detectable fallout indicated that they were not in use, since no uranium was present.

    Basically they lost their ability to produce more weapons grade material. It is unknown how much (if any) was previously made, and might be stockpiled elsewhere.

    It also shows that Iran seems to have remained in compliance, despite trump pulling out of the deal.


  • A lot of places train their police to de-escalate conflicts, as a default. This leads to far more reasonable encounters.

    E.g. in the UK, we have some issues with racism and excessive racial profiling. I know quite a few people who dislike the police (of various ethnic groups). I know very few who fear the police (outside of them doing their job).

    I also know a couple of people who work within the police (backroom). They are actively trying to deal with racism within the force. Unfortunately it’s a bit of a game of whack-a-mole, but at least they are trying.

    America seems to be an exception. Just seeing your police out and about put me mentally on guard. They don’t radiate professionalism, but bully swagger.



  • I had a chat about this with a friend who works for the national grid (UK).

    Apparently the problem is keeping the grid balanced and stable. Basically, the grid struggles to react fast, so they plan ahead. Things like large scale solar can provide predictions on output. Home solar can’t.

    When clouds pass over an area it can cause slumps and surges in the local grid. The more home solar, the worse it gets. The current grid is designed to work top down, with predictable changes in demand. It needs upgrading to deal with large scale bidirectional flows.

    The plug in units are (potentially) even more ropey. If used properly, they are no worse than normal home solar. Unfortunately, being cheaper, there are worries over the microinverters not shutting down. Either due to the manufacturer cheaping out, or turning on an “off grid” mode.

    There are also worries about overloading household circuits. Back feeding bypasses the household circuit breakers and RCDs. They could overload wall wiring and cause fires, or stop an RCD tripping, allowing for a person to be shocked.

    I don’t know how much this would apply to the American Grid, but I would imagine it would be worse. Your grid is older and larger. You also use 120VAC which makes the current overload issue a lot worse.



  • Modern warships basically gave up on heavy armour. Instead they use manoeuvrability and suppressive fire. They are also intended to support each other in a fleet. A single warship, running close escort, loses all these advantages. It can’t outmanoeuvre an attack, and it lacks the firepower to suppress a heavy attack on its own. Iran would make a point to try and sink both the escort ship and its protected cargo ship.

    In order to work, the American navy would have to run a full convoy. A far bigger logistical challenge.




  • The answer is quite mundane. I’ve a few friends in a (non-US) police force. The answer is that the rich/powerful are annoying as hell to go against.

    They either know the law, or pay someone to know it for them. They can make obviously illegal things legal on paper. They can also nitpick everything. E.g. spending £5K on lawyers to get out of a £100 fine, since they don’t want to get the points. Any procedural mistakes, or paperwork errors can kill a case, or at least drag it out for years.

    They also have contacts that can apply pressure. When their wife knows your boss’s, boss’s boss’s wife, they can make your life and career VERY uncomfortable.

    End result, most officers learn to pick their battles with the rich and powerful. They will make your life hard, and will get away without everything being perfect.

    In practice this can easily turn into taking the easy road. Even when the rich aren’t even technically in the right.










  • They are excellent in the hobby world. It’s generally when you need to do a bit of quick logic, an ESP32 can be dropped in to do it. E.g. change the colour of an led depending on a sensor.

    They also form the core of a lot of IoT devices. Simple sensors and relays that can connect to WiFi and throw up a simple web interface. ESPhome, tasmota and WLED exist to make this extremely easy.

    They are basically the hobbiest electronic multi tool. Powerful enough to do most jobs without bothering with code optimisation. Cheap enough to throw in and leave there.


  • In an ideal world, you have conservatives and revolutionaries. The revolutionaries want to make changes to try and make things even better. The conservatives act to maintain the status quo. When they balance properly then you get steady change, but slow enough to detect and fix cascading problems/failures.

    In this situation, the centralists act as the balance point, being swayed one way or the other to set the path.

    Unfortunately the only place this is actually close to accurate is Sci-Fi novels.
