  • For nieve signal distances, that can sometimes be true. That’s not how starlink works however. It bounces the signal between satellites, each adding latency. Overall, fibre wins in almost every situation.

    The bigger problem is saturation. Most things you can apply to radio waves can be applied to light in a fibre. The difference is you can have multiple fibres on the same run. This massively increases bandwidth, and so prevents congestion.

    Just checked the numbers. Starlink is up at 550km. That means a minimum round trip of 1100km. In order to beat a fibre run, you are looking at over 2000km distance. Even halving that to (optimistically) account for angles, that’s still a LONG run to an initial data center.

    Off the joke topic, but something that made it make a lot more sense.

    Scientists have studied this. Women do what are known as IOIs (Indicators of Interest). Most men can pick up on these. When they flirt, the rate doubles, or even more.

    The problem lies in the base rate. It can vary a lot, from 5/hour to 120/hour. At this point men are left with a conundrum. Is a 60/minute lady a 10, desperately flirting, or a 100, who’s slightly off put by you. The lady’s friends have an instinctive read on this rate, so it’s quite obvious. Most men have been burnt however, so tend to be over cautious. This can lead to a lot of flirting at oblivious men, who think you’re just being polite.

    I went to the US for a few days. Their self checkouts seem to be universally awful, compared to the UK or German equivalent.

    While the hardware is far less reliable, and more convoluted, it’s the users that seem the main issue. Self checkout is generally intended (over here) to shift the fast, small shops out of the main queues. 1 big line and a dozen or more tills. In the states they treat it as just another till. Built for trollies, and 1 queue per till. Combined with a slow user and it becomes hell rapidly.




  • Apparently it’s mostly about familiarity. Even if we are annoyed at the time, we will often forget about it completely between then and shopping. By the time we are in the shop, we just have a vague sense of familiarity with the product. We instinctively buy the more familiar, as the “safer” option. It takes conscious effort to overcome this (which most people don’t have to spare).

    In saturated markets, this leads to a zero sum situation. Every customer you get is stolen from a competitor. Apparently the tobacco companies actually loved the UK ban on tobacco advertising. Their ads were intended to counter the ads of their competitors. None of them were roping in new smokers at a high enough rate to matter. The only ones winning were the ad agencies.









  • Officially no. It’s actually something Ozzy was involved in the campaign for. There’s a religious crowd who freak out at the very idea. No government has yet had the will to push updates past them.

    There are however doctors who will happily make a pain med prescription that is “incompatible with life”. If the patient happens to die, while dealing with the pain, well at least they weren’t in pain.

    I believe the police also have a similar mindset. They won’t look too deeply, if they suspect it happened that way, with the patient’s consent. They do have the shadow of Harold Shipman hanging over them however. They missed a serial killer for years, since he was targeting OAPs.


  • There are already plans for metadata signing. I think some high end Canon cameras might do it already. It basically allows proof (via public private key of the hash) that a particular camera took that photo.

    The idea is that you can create a chain of custody with an image. Each edit requires a new signature, with each party responsible for verifying the previous chain, to protect their own reputation.

    It’s far from perfect, but will help a lot with things like legal cases.

    I disagree. I told my wife to “calm down” once, and it worked perfectly. She went from emotional to very calm and focused.

    It might have been at the incongruity that I would actually dare say that, or just the time for her incandescent rage to move to fully focusing on me, but she DID calm down (for 2-3 seconds).
