   Since others are suggesting x86 instead of ARM, I highly recommend an LG Gram (either 16 or 17) that comes with an 80 Wh battery, and stock Fedora. With Power Profiles in Gnome set to "Power Saver" you'll easily last more tha

   My father said: We're not rich enough to by cheap things. I wonder if the original saying has been translated multiple times before getting to English.

   I really like the LG Gram series. I had one of the first generation Gram 17, and this Jan got the 16 (same 16:10 resolution as the 17). My wife has been using Gram 14, and she really likes it. All 3 laptops have been exclusively on Fedora.

   While I totally agree you can easily handle this with Ceph, I would never do it with 2x replication on spinning rust. You can maybe do 2x replication with SSDs if you really know what you're doing and you have data replicated on mul

   And incidentally Ceph supports both S3 and Swift (which I think is the best S3 protocol alternative): https://docs.ceph.com/en/latest/radosgw/swift/

   Not the OP, but that's how I use Signal. It's my default SMS app on my Samsung phone. I have my SMS history there going back multiple years from multiple phones. I'm curious where others in similar situation are moving to.

    I switched to Samsung from SanDisk about 7-8 years ago (when I first discovered this cheating on one of my SanDisk USB sticks) and haven't had any issues. BTW, there is no need to buy anything fancy for RPi, I just buy the cheap stuff,

    I can confirm... Slack works. Sadly, still hogs way too much RAM. This is truly very impressive.

    If we're talking simple math on magnification: It's very easy to find macro lenses that have 5:1 magnification, meaning that an object is projected onto the sensor 5x it's size. Taking 1.7 mm and projecting that onto a Canon

    The fact that it actually comes with a Raspberry Pi is incredibly cool to me. Oh, and of course there's a review of it from Jeff Geerling: https://www.youtube.com/watch?v=-epPf7D8oMk Actually, this thing has some prett

    Ceph is incredibly reliable. I run a ~ 250 PB Ceph install with the equivalent of 1.5 medium-paid full time engineers[0], and I sleep very well at night. Failure after hardware failure, it just keeps running and running. We currently fail

    I love my LG Gram 17 from 3.5 years ago (I think it's a 2018 model). Costco sells them, and when they go on sale, the value can't be beat IMHO. Great screen, amazing battery (even after 3 years), zero issues on Linux (Fedora), lov

    I've not had a single PG inconsistency on my RPi cluster in the one year it's been running. Weekly errors are at work. Most of these are for actual disk media failures. For 100,000 disks what is a normal failure rate in your opin

    Each node is completely separate, housed in a good quality aluminum enclosure with a fan, and sitting on top of an external USB Seagate 2.5" portable drive (either 4TB or 5TB), connected via USB 3 cable. I'm pretty sure these dri

    I just setup a test cluster at work to test this for you: 4 nodes, each node with 2x SAS SSDs, dual 25Gb NICs (one for front-end, one for back-end replication). The test pool is 3x replicated with Snappy compression enabled. On a separate

    When Ceph migrated from Filestore to Bluestore, that enabled data scrubbing and checksumming for data (older versions before Bluestore were only verifying metadata). Ceph (by default) does metadata scrubs every 24 hours, and data scrubs (de

    For production, we have two basic builds, one for block storage, which is all-flash, and one for object storage which is spinning disks plus small NVMe for metadata/Bluestore DB/WAL. The best way to run Ceph is to build as small a

    I would say the minimum is whatever your biggest replication or erasure coding config is, plus 1. So, with just replicated setups, that's 4 nodes, and with EC 4+2, that's 7 nodes. With EC 8+3, which is pretty common for object s

    Aside from running Ceph as my day job, I have a 9-node Ceph cluster on Rasberry Pi 4s at home that I've been running for a year now, and I'm slowly starting to move things away from ZFS to this cluster as my main storage. My setup

    Ceph is incredibly stable and resilient. I've run Ceph at two Fortune 50 companies since 2013 to now, and I've not lost a single production object. We've had outages, yes, but not because of Ceph, it was always something els

    I'm on Fedora 36 laptop that started from Fedora 25, and at some point in the middle I moved from Dell XPS to LG Gram. To migrate machines I didn't use rsync, used dd instead. Zero upgrade issues, however I generally wait 2-3 mont

    Wow, I haven't heard of these "catastrophic failures" previously... that's a bummer. The previous generation certainly worked. Is there an article that explains this in more technical detail?
