PM2.5 on the balcony hit 350μ/m³ at 5AM in c/toronto@lemmy.ca

I'm guessing it's different density of the smoke clouds. Even if they rise consistently over the burning area, they could still form patterns of higher and lower density as they move. Think patterns in smoke from a cig or candle as it rises and moves - curls and gaps forming in it. Not sure what that's called or caused by in fluid dynamics but I assume that happens in the smoke clouds as they travel south. So when we get lower density bit over us - numbers go down, hgher density - they go up.

    Nowhere yet. Still on Discord since Discord backpedaled on their ID bullshit. We'll have to reexamine again at some point. It seems there may be some other alternatives to look into like Stoat or Fluxer.

    BTW I'm not at all a fan of the Discord format but it's not my decision to use that format.

    Been contributing monthly since I joimed in 2023. It's approaching my cell phone bill. Not complaining, just saying I got that part covered. 😄

    Still, I can't demand extra free labour but in case it was already done.. or someone was about to do it.. 🤭

    Being poor sucks.

    No kidding. This didn't ruin me but it was painful. And on top of that, it's smaller disks for significantly more than I did last year.

    I bought them for years ahead. My primary pool is gonna start having drives fail from age and use, and it'll need replacements. So I'm gonna be sticking these in as they fail over time so I use all the service life I can get from the existing (8TB) drives.

    • Quality difference between Shimano Alivio and XT derailleurs in c/bicycles@lemmy.ca
    [–] [S] 1 point 8 months ago* (last edited 8 months ago)

    The M8000 derailleur/shifter on my bike are from 2017. The cassette is M7000 (SLX) which is also that old. I've done at least 25000km on this drivetrain. Probably closer to 30-40K. I don't clean it regularly. Maybe once every 2 years. Last year I shamefully fell behind on maintenance and rode it dry almost all summer. This drivetrain still shifts perfectly and new chains don't skip on the cassette. Point being that if this anecdata is any measure, even old, used compontents from these series might work great, if you find some cheap deal.

    Quality difference between Shimano Alivio and XT derailleurs (mastodon.social)

    This is the reason a #Shimano XT #derailleur costs more than a Shimano Alivio. On the left you have the whole-body slop of an Alivio M3100 derailleur. On the right you have the same of an XT M8000. There's noticeable slack in all the pivot joints of the M3100. There's no noticeable slack in the XT. It feels like a single piece. The result of this difference is misshifts like going one gear higher then back to the desired one, or otherwise some shifts taking longer between gears.

    There's a second video in the original post showing the XT derailleur.

    So I have an update to my post from a couple of weeks ago. I did a few full charging sessions and they all showed estimated capacity around 4700mAh:

    Then yesterday I found this curious setting, after updating to Android 16 QPR1:

    I turned it off, did a full charge session and I got this estimate:

    And that result looks to be right back to the normal cycle degradation line:

    I'll do a few more full charge sessions but we have a tentative culprit. Google seems to have introduced a battery capacity cap under this setting, presumably to extend the cycle life of the battery.
