  • May I present to you, how to measure like a Brit

    Flow chart showing the uses for metric and imperial in the UK

    It’s great fun especially when you’re trying to work out how fuel efficient your car has been when your tank and fuel pump is in litres and the fuel efficiency is in miles per gallon.

    Oh and you’ll have a jolly time following a recipe from more than 20 years ago trying to remember what the hell “Gas Mark 4” is in centigrade for fan or convection ovens.

    Oh and my personal favourite for the industry I’m in: when designing a PCB your component sizes will use imperial codes, your wire diameters will be in AWG, your track widths and PCB dimensions will be in millimetres, but your copper thicknesses will be in ounces despite the final weight for the assembly will be in grams.





  • Once again, UK investment and implementation of infrastructure is shite not the concept of smart meters.

    For an example of a proper smart meter implementation nationwide, look at Estonia.

    100% coverage. Works brilliantly.

    In fact it works so well there’s companies that use the data generated by the smart meters to predict faults on the grid on the Low Voltage (LV = less than 2000 - 1000V in the electricity transmission world). That is unheard-of elsewhere because you’d normally have to install LV monitors for a few months on a location where faults have occurred to try and find it.

    Fucking Tories, fucking Westminster, fucking civil service, fucking national grid, and the fucking utility companies all dragging their heels over this because the entire energy grid is privatised whereas anywhere else sensible, the national electricity backbone is nationalised with local networks semi or fully private.

    The post-grad assistant helping me with that assignment night before it’s due:

    “Oh that’s easy, just apply Kirchoff’s Gambit. Here’s the solution because the lecturer hasn’t changed the assignment questions since they started here 20 years ago.”

    Me, wide eyed: “You are an angel amongst demons!”
