  • So I used to return my carts all the time. Then I actually talked to people who grab carts. They appreciate getting the stray carts because it’s the only time they have to check their phone and just get some time.

    Then I asked myself… am I putting the carts away because that’s what I was trained to do by capitalism or is it because it’s the “right” thing to do? My response to that question is somewhere in the middle between the extremes.











  • L2ARC only does metadata out of the box. You have to tell it to do data & metadata. Plus for everything in L2ARC there has to be a memory page for it. So for that reason it’s better to max out your system memory before doing L2ARC.

    It’s also not a cache in the way that LVMCACHE and BCACHE are.

    At least that’s my understanding from having used it on storage servers and reading the documentation.


  • I used to do this all the time! So in terms of speed bcache is the fastest, but it’s not as well supported as lvm cache. IMHO lvm cache is plenty fast enough for most uses.

    Is it going to be as fast as a NVME ssd? Nope. But it should be about as fast as a SATA ssd if not a little slower depending on how it’s getting the data. If you’re willing to take that trade off it’s worth it. Though anything already cached is going to be accessed at NVME speeds.

    So it’s totally worth it if you need bigger storage but can’t afford the SSD. I would go bigger in your HDD though, if you can. Because unless you’re accessing more than the capacity of your SSD frequently; the caching will work extremely well for both reads and writes. So your steam games will feel like they’re on a SSD, most of the time, and everything else you do will “feel” snappy too.

    I’ve never in my entire life wanted something more than to see copycats going after the C-Suite of places that put profits over people, especially when they’re running a company that should not exist. Because then maybe… politicians will finally get some meaningful reforms. Because they sure as hell don’t care about dead kids. Thoughts and prayers!!!
