  • You can’t. You can, however tell if a particular URL is believed to be dangerous by any of several organizations that track such things.

    Your browser probably has something built in; Firefox and Chrome do, for example. If you attempt to visit a known-bad URL, the browser will warn you and make you click through the warning before you do. Some other comments in this thread suggest third-party services that will also do this, and may even attempt to check the content found at the URL for known malware.





  • Quite. Unfortunately, most devices that use modern batteries have the battery sealed inside with an onboard charging system, such that when the battery wears out, the device becomes e-waste. There are many standard, or semistandard sizes of cylindrical lithium-ion cells, and devices could be designed for field-replaceable versions, but the only product category where it’s common is high-performance flashlights.

    Even in common consumer form factors, there have been improvements. Here’s a test of one of the best alkaline AAs. Note how the capacity drops as the load increases - by a factor of about six at 3 Amps. Contrast the Eneloop NiMH rechargeable, which has less capacity under light load, but barely loses any at 3 Amps and can handle 10 Amps while retaining most of its capacity.

    The best Li-ions in a form factor similar to AA, called 14500 have even better performance with over 5 Watt-hours of energy, but devices have to be designed for them since the voltage is much higher; putting one in most devices designed for AA will result in damage, if not fire.


  • We know reddit used bots at the beginning to generate activity to make the site look popular.

    That’s not quite it. The founders made a few of throwaway accounts and posted a bunch of links that exemplified what they wanted people to post. It was fake activity, but I’m pretty sure it wasn’t automated. It was maybe 50 posts and I don’t think it was a bad thing to do.

    Yes. I could talk about quantum indeterminacy as a scientific argument for it, but fundamentally, I believe in it because I want to[1]. I don’t like the idea of being a deterministic machine with a fate I can’t influence with active choices. It’s not provable either way with the current state of science, so I choose to believe my preferred option is the correct one.

    [1] Of course such a statement presumes free will. I think I want to, anyway.
