    I would NEVER recommend a modern HP printer, but…I have a HP Laserjet 4000 (Circa 1997) that I ‘acquired’ from the company I worked for that went bankrupt.

    This thing refuses to die. current impression count is over 500,000 prints. All its patents expired over a decade ago, and it’s still easy to find parts and toner (originals, and now even 3rd party knockoffs). It’s old enough now that modern generic drivers have built in support for it. The only parts I’ve ever had to replace are the rubber sheet feeder rollers which dry out and stop working correctly after 12-15 years.

    So, I guess the point here is that some really solid printers were made a couple decades ago, back when manufacturers still took pride in their products, and they are old enough that the hardware is no longer protected by patents (so practically open) and robust driver support without all the bullshit. Picking up something from this era and cleaning it up would come close to satisfying a lot of your requirements.




  • Putting a Netflix show on DVD and selling it is absolutely illegal unless they have a distribution license provided by the copyright holder.

    It would be legal after copyright expires (in the US, copyright exists for the lifespan of the author/creator + 70 years). Keep in mind that the US has stricter copyright laws than most of the rest of the world.

    For other items, like physical functional items, reproductions are generally legal unless the item is patented. And it would still not be legal for the reproduction to also reproduce any registered names or trademarks associated with the original. Example: you could legally reproduce and sell knockoff Nike Air Jordans as long as you didn’t use the Nike swoosh or any likenesses of the copyrighted artwork. For items that are patented, or patent pending - making and selling reproductions is illegal - and for most patented items the reproduction doesn’t even have to be identical for it to be infringing, just replicating the functionality is probably infringing.






  • Some were produced that were claimed to be dimmable - and I wasted my money on a few and was still unhappy with them. The other problem I forgot to mention earlier was the startup time: the earlier bulbs (and the cheaper ones) wouldn’t just ‘turn on’ when the power was turned on…they took some time to start making light, and the colder it was the longer it took - this is an aspect where LEDs are amazing - maximum brightness within milliseconds of getting energized.


  • One problem is that CFL bulbs is that they contain small amounts of mercury (about 4mg per bulb). Because of that, disposing of them responsibly requires going through big hassles rather than just throwing them in the trash. Also, because of that mercury, accidentally breaking one means contamination of the environment around the break.

    Flickering - always was a big problem for these things.

    Longevity: They were very sensitive to heat, which meant that they loved to burn themselves up in a lot of applications.

    Dimming: CFLs were NEVER good at being dimmable.

    CFL was just a very poor technology detour on the way to the vastly superior LED lights.
