Will it be easy for me, a non-expert, to install OpenOffice to this Windows machine? 18:48 ------------------------------------------------------------------------- Brendan Kidwell (NYC) Brendan Kidwell (NYC) says:are there people speaking? I'm not receiving sound 18:48 ------------------------------------------------------------------------- John Abreau says:yes, a bunch of us are speaking 18:48 ------------------------------------------------------------------------- Brendan Kidwell (NYC) says:what do you have to do to make brave on linux play sound in jitsi? Brendan Kidwell (NYC) says:I had the same result on my Fire tablet 18:48 ------------------------------------------------------------------------- Ed Piecewicz says:My Comcast service was up and down all day Monday. From what I found online, they apparently installed something called a "harmonic node", which will provide something for mid-split, eventually. Multi-gigabit speeds forthcoming. 18:49 ------------------------------------------------------------------------- Brendan Kidwell (NYC) says:jitsi is making notification sounds, but I'm hearing no participants speak 18:49 ------------------------------------------------------------------------- dsr says:Paul: very easy, but you want LibreOffice, not OpenOffice. See www.libreoffice.org 18:49 ------------------------------------------------------------------------- Brendan Kidwell (NYC) says:solution: you have to enable autoplay on this domain Brendan Kidwell (NYC) says:Fire tablet: I have no idea. I know that I failed to upgrade jitsi in f-droid because the <10 year old board is abandoned by android 18:51 ------------------------------------------------------------------------- Ed Piecewicz says:Never heard of ZFS. 18:52 ------------------------------------------------------------------------- dsr says:ZFS is a filesystem. Now you've heard of it 😃 18:53 ------------------------------------------------------------------------- Ed Piecewicz says:👍 18:53 ------------------------------------------------------------------------- John Abreau says:Zettabyte File System 18:59 ------------------------------------------------------------------------- Mark Woodward says:Created by Sun 18:59 ------------------------------------------------------------------------- Brendan Kidwell (NYC) says:does it work with 1GB workloads? :^) 19:00' ------------------------------------------------------------------------- Mark Woodward says:What do you mean? 19:00 ------------------------------------------------------------------------- Brendan Kidwell (NYC) says:just joking 19:00 ------------------------------------------------------------------------- Jerry Feldman says:Ive known about it for many years, but never delved into it. 19:00 ------------------------------------------------------------------------- dsr says:People often use a couple of 1 GB files as test volumes early on. 19:00 ------------------------------------------------------------------------- Paul Jameson says:I'm now using Firefox but I still can't be heard. Don't know why. 19:01 ------------------------------------------------------------------------- Bill Ricker says:I have theoretical knowledge about CoW and Snapshots but not practical 19:02 ------------------------------------------------------------------------- John Abreau says:set up a FreeNAS server at home. BSD-based, uses ZFS for drives. Never delved into all the ZFSS features 19:02 ------------------------------------------------------------------------- dsr says:As of last weekend, my workplace went from "ZFS is nice for backup" to "ZFS is storing all our databases" dsr says:Facebook has said that it's using BTRFS internally; they are probably the biggest user. 19:09 ------------------------------------------------------------------------- Bill Ricker says:FB is going to the biggest user of anything they use, unless Google does also :_D 19:12 ------------------------------------------------------------------------- Michael I (he/him) says:Is this redirect-on-write like the NetApp WAFL fs? 19:15 ------------------------------------------------------------------------- dsr says:Similar, but not infringing. dsr says:deduplication being ZFS's worst implemented feature 19:17 ------------------------------------------------------------------------- Bill Ricker says:NetApp and Sun had a sealed settlement on a patent infringement claim. So maybe yes, but settled. Bill Ricker says:Making a _commercial_ product with OpenZFS outside of Oracle/Sun support (and thus protected by settlement) might be hazardous especially if competing with NetAPP Bill Ricker says:IANAL YMMV etc 19:18 ------------------------------------------------------------------------- dsr says:The bigger hazard would probably be Oracle. Who wants to go to court against them? 19:18 ------------------------------------------------------------------------- Bill Ricker says:Well Bill Ricker says:OpenZFS is forked off the OpenSolaris CDDL ZFS, so Oracle shouldn't be a problem but being anywhere near evil prince larry is hazardous ... 19:19 ------------------------------------------------------------------------- dsr says:Indeed. (The ZFS change at work went hand-in-hand with the "kick out Oracle" transition.) 19:20 ------------------------------------------------------------------------- Jerry Feldman says: https://en.wikipedia.org/wiki/Merkle_tree 19:22 ------------------------------------------------------------------------- dsr says:The speed of taking a snapshot is extremely valuable: you can stop a database, take a snapshot, restart the database, and then spend hours getting the data snapshot off to where you really want it. dsr says:(i.e. a backup server in another power grid) dsr says:If you don't run another filesystem on top of ZFS, snapshots can be accessed through the hidden .zfs directory in each mount point. Restoring from a point-in-time is just a cp or rsync away. dsr says:If you only want a backup target, the receiving machine doesn't need to have ZFS installed at all. zfs send creates a stream of data that can be saved in a file (by cat, e.g.) and then zfs recv can operate on a stream sent the same way. dsr says:This is also how you can get a ZFS encrypted backup over to a machine which cannot possibly decrypt it. (Make sure you save the keys elsewhere!) dsr says:rsnapshot uses cool features of linking to do incremental backups. 19:48 ------------------------------------------------------------------------- Jerry Feldman says:This is true. Uses rsync. 19:49 ------------------------------------------------------------------------- dsr says:zfs send doesn't actually care what the receiver is, as long as there's a way of getting the same data back out. dsr says: https://github.com/presslabs/z3 is a ZFS to S3 tool. 19:53 ------------------------------------------------------------------------- Curt Curt says:any issues with Raid? 19:59 ------------------------------------------------------------------------- dsr says:ZFS wants to manage the RAID itself. It can arrange single disks, mirrors, RAID5-equivalent, RAID6-equivalent, and for big disk systems, RAIDZ3, which uses three parity disks per vdev. dsr says:Think of it as a replacement for md as well as for LVM. dsr says:There are distributions which make it easier to do ZFS on root; without distro support, most people don't want to deal with that. Establishing a zpool on a non-root partition is quite easy. 20:05 ------------------------------------------------------------------------- Curt says:thanks 20:09 ------------------------------------------------------------------------- Ed Piecewicz says:Thank you. Ed Piecewicz says:I have Fedora Rawhide in a VirtualBox, it defaulted to BTRFS for the install. 20:12 ------------------------------------------------------------------------- Jerry Feldman says:Was default in 36 Jerry Feldman says:maybe 35 20:14 ------------------------------------------------------------------------- Michael I (he/him) says:f33 https://fedoraproject.org/wiki/Changes/BtrfsByDefault you're welcome 20:21 ------------------------------------------------------------------------- Jerry Feldman says:Facebook, Fujitsu, Fusion-IO, Intel, Linux Foundation, Netgear, Oracle Corporation, Red Hat, STRATO AG, and openSUSE Jerry Feldman says:btrfs develop[ers 20:23 ------------------------------------------------------------------------- Michael I (he/him) says: https://stratis-storage.github.io/ 20:25 ------------------------------------------------------------------------- Brendan Kidwell (NYC) says: https://github.com/rfjakob/gocryptfs https://github.com/bailey27/cppcryptfs 20:27 ------------------------------------------------------------------------- Bill Ricker says:(a current client uses an API that a Stratus is on the other end of still, and the other API talks to a Tandem. ) 20:27 ------------------------------------------------------------------------- Paul Jameson says:How does a Tesla know the speed limit? 20:31 ------------------------------------------------------------------------- Ed Piecewicz says:V2X https://arstechnica.com/cars/2022/08/v2x-is-finally-dead-as-court-refuses-to-stop-fccs-5-9-ghz-reallocation/ Ed Piecewicz says:Thank you. 20:38 ------------------------------------------------------------------------- meeting ended at 8:39 pm
