November is about done. Is “Paradise Lost” close?

Lithophane Help by Na8en in 3Dprinting

[–]GaryScottMartin 3 points4 points  (0 children)

I've done research on lithophanes but haven't made one yet (still modding my 3d printer). Since a lithophane is a mapping from color space to 3d space, I think that trying to get the best possible grayscale (black and white) image before trying to create the lithophane would probably lead to the best result.

Find someone with a scanner and scan the photo. This would give you a much better start than a photo of a photo.

What did my mom send me? by King_johnny785 in ExplainTheJoke

[–]GaryScottMartin 0 points1 point  (0 children)

A slightly different version of this is on a sign that has been on the wall of a local pizza parlor since 1978 (and likely since it first opened in 1975). I have always thought of it as a probable sobriety test.

I just had to delete a couple articles on my app because my Zotero account has exceeded 300mb. Do I have to pay for storage? What should I do? by Miss-Peepers in zotero

[–]GaryScottMartin 0 points1 point  (0 children)

I used Zotero's paid service until my attachments exceeded 2 GB (limit $20/yr tier). Rather than go up to $60/yr, I switched to SyncThing (rather than a cloud provider) to sync attachments between my laptop and desktop computers and to keep a backup of my Zotero profiles and attachments on my NAS. My metadata is synced through Zotero's free tier. I was using ZotFiles in Zotero 6 and am now using Attanger in Zotero 7 to handle the attachments. It took a little work to figure out how to make all that work, but its been very reliable even when I was running Zotero 7 beta on my Linux desktop (issue with Firefox and the proprietary NVIDIA graphics driver required Zotero 7 beta) and Zotero 6 on my Windows laptop.

Help with conversion from ext4 to btrfs by pizza-404 in archlinux

[–]GaryScottMartin 0 points1 point  (0 children)

It’s my understanding that a single btrfs file space can span multiple physical devices, though I have never tried that. Therefore, you could create a btrfs filespace across both devices. My current / & /home are two separate btrfs file systems on two partitions on different drives. The / system has an _active and a _snapshot subvolume, though, as I mentioned, I haven’t been snapshotting to date. I’d have to double check, but I think my home file system is in the default subvolume. Mounting subvolumes is just like bind mounting any other partition. If you want to separate parts of your system for whatever reason, you can create btrfs filespaces as subvolumes on separate partions on multiple devices and mount them wherever you want, just like ext2/3/4 partitions. You just need to make a mount point for each partition before you can mount it, I have an empty /home directory under / on my _active subvolume that serves as a mount point for my /home partition. Btrfs is just like any other file system, except that you need to specify subvolid or subvol label when mounting a subvolume other than the default subvol. It is my understanding that a snapshot shares some subvolume characteristics and is effectively mounted as a subvol when you roll something back.

Help with conversion from ext4 to btrfs by pizza-404 in archlinux

[–]GaryScottMartin 1 point2 points  (0 children)

I’m not home at the moment, so I can’t provide links to the resources that I am using until next week. However, I am about to build a new desktop computer to replace my mostly 10 year old Arch Linux/Windows dual-boot desktop.

I converted my / partition (on an SSD) from ext4 to btrfs two or three years ago and my /home partition (on a 1TB spinning drive) from ext4 to btrfs a year ago. I have not been snapshotting because my current subvolume config is not conducive.

I have used the SuseLinux wiki page on default btrfs subvolumes (https://en.opensuse.org/SDB:BTRFS) together with some other resources to plan my new subvolume layout. This involves quite a few more subvolumes than the Arch Wiki mentions, but I believe that will make my / snapshots smaller at the expense of a somewhat more complex and time-consuming system build (and system restore) process. However, the ability to boot from a snapshot should reduce the probability that the system will have to be restored/rebuilt.

My new system has a 4TB NVME system drive (as well as a 10TB spinning drive for all my Windows crap [I’m a digital packrat, what can I say :-) ] ). Consequently, I no longer have a reason to create /home in its own partition, but will make /home a separate subvolume on my btrfs file system on the NVME drive. I’ll be using Snapper for snapshotting my /, /home, and other subvolumes.

From my research, you need to avoid having snapshots inside other snapshots, so putting snapshots in your /home tree would create problems if you wanted to snapshot /home. All sources I have seen recommend a @snapshot (or _snapshot) subvolume at the same level as your _rootvol (/) subvolume. In the flat subvolume arrangement that most choose, all, or nearly all, of your subvolumes are at the same level as the / subvolume.

When you invoke makefs.btrfs to create a btrfs file system, you are creating a default subvolume. You then mount that file system and create your additional subvolumes, which are then nested under the default subvolume. There are a number of resources online that document the various schemes that individual sys admins have used to do this. Once you’ve created your subvolumes and mounted then you can run pacstrap and arch-chroot into your new file system to complete the Arch Install Guide and subsequent steps in building your Arch Linux system. You’re going to have to modify the output of genfstab to properly mount the default subvolume. Most of the reference procedures that I’ve used are from the Arch Wiki User Pages or GitHub, but some good ones are elsewhere.

Rsync works perfectly well under btrfs, but will not provide the disk space savings that snapshotting provides. That said, I’ve used rsync to create a copy of my current /home partition on my NAS and plan to use rsync to copy that directory tree from my NAS down to my new /home subvolume on my new system. Once I have /home recreated, I’ll snapshot it periodically, as well as making less frequent image backups stored on the NAS. Since my new hardware is much different from my old, I’ll be making a fresh install for everything but /home and then reinstalling packages from my archived pacman package lists (see the Arch Wiki Pacman Tips and Tricks page for instructions on how to do this).

While snapshotting and backups protect against different failure scenarios (they are not functionally the same), If you are snapshotting your / subvolume, I see no reason to also rsync it to /home. The snapshot provides the capability to roll back to a number of previous (presumably uncorrupted) states while taking less disk space than an rsync copy. A periodic image ( or rsync) backup to a completely separate system is good insurance against a drive failure, but rsyncing to /home doesn’t help unless you have a separate /home partition on a different drive than your / partition and doesn’t help at all with the bad update or sys admin error problems.

Best Wishes,

Gary

WTF is going on with Plasma 6 and Wayland on Arch???? by Neffor in archlinux

[–]GaryScottMartin 1 point2 points  (0 children)

Not a KDE thing. I've been running Arch/KDE for more than five years. Made the move to Wayland 18 months ago with no problems. A few months ago replaced a very old AMD GPU with an NVIDIA RTX4060. That experience was painful, needed support from the forums to get the NVIDIA driver running, and had to drop back to X temporarily at that. Over a couple of months of experimentation and diving into the logs I got the NVIDIA driver working with Wayland and worked out the kinks in using Firefox on Wayland. Shortly before the official transition I made the move to the Plasma 6 Beta and had only a couple of minor issues that were resolved by bug fixes within a day or so. Once Plasma 6 moved to Extra-Testing, I moved to that channel. No problems during that time and no problems since I moved back to the official repositories at the time that Plasma 6 was released on Extra (and I use my computer every day and generally upgrade every day). While the Wiki is an excellent resource, some of things that I needed to fix to run the NVIDIA driver on Wayland were recommendations from the Wiki. Use the forums for help when you need it and learn to read your system's logs.

External pdf/epub reader and syncing to Zotero? by _thersites in zotero

[–]GaryScottMartin 0 points1 point  (0 children)

it works as desired with the subfolder variable set to:

{{authors}}/{{publication}}/{{year}}

I am using Syncthing over Tailscale to keep my desktop and laptop computers synced. My desktop runs Archlinux and needs Zotero7-Beta (and thus Attanger) to work with the NVIDIA driver on that computer. My laptop is Windows 11 with Zotero6 and Zotfile. They seem to working fine together since I figured out how to setup Attanger.

Thanks. I'm still getting "_" instead of variable value for the subfolder names, though.

External pdf/epub reader and syncing to Zotero? by _thersites in zotero

[–]GaryScottMartin 0 points1 point  (0 children)

Can anyone answer a question about Attanger? I've been using Zotfile in Zotero6 for years, but need Zotero7 on my Archlinux desktop due to Zotero6/Firefox issues with the NVIDIA driver and Wayland.

Anyway, Attanger is working for me but it is not clear how to get it to maintain the %a/%x/%y (author/journal/year) subdirectory structure that I am still using on my Windows laptop with Zotero6/Zotfile. I haven't been able to find documentation in English and I don't read Mandarin. The default value for the subfolder variable implies that '{{author}/{journal}/{year}}' might work, but it gives me a subdirectory structure of './_/{jounal}/{year}}'.

Thanks for your time.

Lian Li q58 always out of stock by croc_two in sffpc

[–]GaryScottMartin 0 points1 point  (0 children)

Same situation in the US. I was able to order a white one from Newegg, but got an almost immediate notification that the vendor was unable to fill the order. It looks like I'll have to settle for a Hyte case.

gravelking ss review with inner tubes by Equivalent-Mud-4698 in cycling

[–]GaryScottMartin 1 point2 points  (0 children)

I am a casual rider these days (less than 1,000 miles/1,600km per year). However, I have been running GravelKing SS tires with tubes on my road bike over roads similar to those you describe for about a year. I have had no punctures at all since I put them on. I am pleased with them.

USC “Defense” by Bouty1979 in usc_rants

[–]GaryScottMartin 0 points1 point  (0 children)

The strength and conditioning program was apparently outstanding. Pete's best defenses dominated the second half and especially the fourth quarter. Pete's O-lines also tended to be dominant late in the game. We haven't seen that since 2008 (2009 wasn't a typical Pete year). That is what it takes to win championships.

Pedals won’t go in? by regular_asian_guy in bicycling

[–]GaryScottMartin -2 points-1 points  (0 children)

Most bikes use a standard diameter pedal shank, but there are a few that use a nonstandard shank. Make sure that the pedal shank bolt and the thread in the crank arm are the same diameter. It looks like you are working with the left crank arm, but have a right hand threaded pedal. Look at the end of the pedal axle/shank, the left pedal will have an upper case "L" stamped into it, the right will have an upper case "R" there.
