  • A bit clickbait title:

    The boy’s skin was darker than most modern Europeans’ but not as dark as a tropically acclimated person’s, Modi says, and his pale blue eyes match those of other ancient western European hunter-gatherers. The infant also appears to be an ancestor of the Villabruna cluster—a group of post-Ice Age people who lived up to 14,000 years ago—suggesting the Villabruna line began in southern Europe well before the end of the Ice Age, per the study.

    I would be interested if some relatives are still living nearby. Remember I read an article about some bog mummy from England, and they found direct descendants living in a nearby village.





  • Other benefit of zigbee that devices can’t connect directly to the internet, so you don’t have to trust them, you don’t have to create vlans, they can’t be turned into a botnet. Also in zigbee every device can be a router, so they can more easily cover bigger houses.

    I wouldn’t replace a wifi based system with zigbee, but recommend it to anyone starting now. This post wanted to be an advice to newcomers…


  • Ikea bulbs use zigbee, their prices are very good and they are more reliable than chinese stuff.

    It’s up to you how you automate your smart home. My useful light related automations:

    • When I arrive home and the light sensor see it’s dark it switches on the living room light
    • if I pause a movie in jellyfin it turns on a light, if I hit play it switches it off
    • The off timer of a movement activated light depends on if my projector is turned on, it switches off more quickly when the projector is on
    • If I’m not home it switches off everything automatically, so I can’t forget any lights on

  • I have an old wifi yeelight, measured it now because I was interested. 1.4W off, 8.4W full power

    For comparison, Ikea zigbee bulb 9.3W max power, less than 0.1 W while off, but switches on instantly. My watt meter can’t measure less than 0.1W so it shows 0.0W.

    Zigbee was designed for this kind of usage. I have several zigbee sensors running on 3.3V coin cell batteries, they can report data for years without battery replacement.


  • These are terrible advices.

    All smart lightbulbs have a small router in them, so they all use some electricity while switched off. You can gain some net plus only if you live with people who constantly forget to switch off lights. But you need some presence detector as well. Smart lighting is about convenience not energy usage.

    Wifi is the worst wireless standard from energy usage standpoint. Zigbee’s power usage is much less and devices are cheap. Thread and Z-wave power usage also lower than wifi, but devices are a bit more expensive.

    Amazon and Google are a privacy nightmare. Home Assistant and Domoticz are two wellknown local first smart home systems.


  • Wrong title, it should be:

    A Map of the world showing where the local time zone is wrong more than half hours

    An hour is a human concept, we just divided the day to 24 parts, we could use whatever else division. Local time is correct only on the center longitude, which is a line with zero thickness.

    Also it’s clearly visible that France and Spain are in the wrong time zone, and it was changed by the Nazis. Before WW2 France and Spain was in the same zone as Britain. France changed because of the German occupation, and they forgot to change back after the war.

    It’s in a lot of program, not just ff. You can also see some letters are underlined in that menu, if you press that letter after alt, it would invoke that command or open that drop down without using the mouse. This is a convention at least from DOS, but I suspect it may be even older.

    So actually alt doesn’t unhide the menu, it waits for a letter input to what command you want to start. It just happened that this old type of menu is hidden by default in a lot of programs and alt could be reused for this as well.
