  • not multiple bulbs no, but those bulbs have multiple LEDs in them… LEDs only have a single colour, but you can produce variable colour (or colour temperature) bulbs by mixing R/G/B or warm white and cold white

    philips hue bulbs for example have red, green, blue, warm white, and cold white LEDs so they can mix any colour or colour temperature

    to have variable colour temperature requires a warm white and a cold white LED that get mixed, so they’re always being used at 50% or less (because 50% emission on both is the same brightness as 100% of 1)… commercial fixtures are likely to not give that option and only include a single LED at fixed colour temperature to avoid 2x the parts





  • kinda different there though… it’s trivial to add whatever data you like to images etc (and that’s without even resorting to steganography), but that data is only accessible with an application. i believe the question was intended as whether you could get a virus from downloading/playing media files… the content of that “hidden data” isn’t executable, so whilst it’s reasonable to say it’s possible to transport a virus via hidden data in media, it’s not reasonable to say that you can “get” a virus using that same method alone




  • sooooo yes you’re not wrong, but i’d argue (as not an american mind you) that also it’s a little more complicated than just national defence

    overseas military bases aren’t just for intimidating other countries into doing what the US wants: they also contribute significantly to global stability… having THE world super power kinda everywhere means it’s probably much less likely that some random country is going to start shit… sure, the US gets to pick and choose to benefit itself, but it certainly contributes

    and that’s not just good for the world: AS the worlds leading superpower, the US benefits enormously from global stability: from cheap trade, financing, more global budget being spent on STEM/R&D (which because of trade and financing the US almost always capitalises on somehow!)
