Canadian hosting?
by Stewart C. Russell 14 Apr '23

14 Apr '23

I know that Akamai Cloud (formerly Linode) has dedicated root Linux servers in Toronto, but is there anyone else non-terrible*? There's a potential client who absolutely must have all data and processing hosted in Canada. I realize there's probably a 3x (or more) premium for in-country hosting. Any suggestions/caveats greatly appreciated. Best Wishes, Stewart *: your definition is fine. I don't know enough to have an opinion

how I sign PDFs
by D. Hugh Redelmeier 13 Apr '23

13 Apr '23

We don't seem to have a Public Key Infrastructure that makes digital (cryptographic) signatures useful for non-computer work. I think signing a document is a solemn act. So I don't want to just paste a .PNG of my signature, I want to actually sign it. I don't have a modern Linux device with a stylus. (Somewhere I have a ThinkPad x61 and a couple of Sharp Zaurus PDAs.) I do have an iPad and a ThinkPad C13 ChromeBook, both of which have styli. In each case it is a little intricate so I thought others might find my methods useful. Suggestions welcome. On the iPad: - I can plug in the ipad to a USB port of my desktop and instruct the iPad to act like an external disk drive - using Gnome Files, I can transfer the PDF to a directory on the iPad. - using the file browser on the iPad, I navigate to the PDF, long press on it, and select "Quick View". I don't want Adobe tools. - I can just write on the document with the stylus and save it. I usually save it with a different name, one that indicates that it is a signed document. - using Gnome Files, I copy the signed document from the iPad to my desktop. - Using Gnome Files, I "eject" the two removable filesystems that are the iPad's. I can then unplug the iPad On the Chromebook: - I have already installed the Linux subsystem. I start up the terminal in the Linux container. - I use scp to copy the PDF from the desktop to ChromeBook's Linux filesystem (my home directory) - I use the ChromeOS Files application to open the PDF file (the Linux container's filesystem is visible to Files). - I tap a snake-like symbol on the top of the screen (It seems to signify scribbling). - I write my signature - I save the result, with a distinct name, in the Linux Container filesystem - back in the terminal, I issue the scp with the arguments suitably adjusted (easy to type with bash's history mechanism). I find the ChromeBook a bit easier. Partly because WiFi is easier than wiring (I have only one lightening cable and it is usually hooked up to a charger). If I found an iOS SCP application that might even the platforms.

Anyone need 8GB (4x2GB) DDR2 memory sticks? Otherwise, it's to the garbage.

war story: gtalug.org's filled up
by D. Hugh Redelmeier 06 Apr '23

06 Apr '23

(This post is also a test of whether the mailing list is working.) GTALUG's server's filesystem filled up: little disk space left. I discovered this when I tried to do "apt update; apt full-upgrade". The second step failed, saying that /var/cache/apt/archives had no room. This means that / has no room because / contains that directory. Tip: "df /some/path" will tell you how much space is used on the filesystem containing /some/path and it will tell you the mount point of that file system. I wandered around the filesystem, doing: sudo df -s * | sort -n This command lists things in the current directory, and their sizes, largest last. (It skips things with names starting with ".".) Pretty soon, I found that most of the space was taken up by /var/cache/apt/archives after all. This kind of surprised me. Googling got me to others with this problem. The advice: sudo apt autoclean That gave back (only) 3% of the disk. That directory was still way too big. Most of the space was taken by 35 versions of gitlab-runner. I have no idea why we need multiple versions. Violence is sometimes the answer. sudo apt clean That left only 32% of / used. Note /var/cache/apt/archives is only a cache. If the system wants any of these, it should be able to find them in a repo.

I imagine not. I don't see gitlab-runner as a package in my Ubuntu repos, but I believe the 153 versions are all different versions that currently exist in the repo. I tested this with Firefox, and `apt show firefox` contained: > Version: 111.0.1+build2-0ubuntu0.22.04.1~mt1 > > ... > > "N: There are 2 additional records. Please use the -a switch to see > them." Whereas `apt show firefox -a` indicates there are versions 110.x, 111.x and snap available. So, all the un-removed packages in cache corresponding with existing entries in the repo may explain why `apt autoclean` didn't clear up much space (if I recall the situation correctly), since `man apt autoclean` says: > autoclean (and the auto-clean alias since 1.1) Like clean, autoclean > clears out the local repository of retrieved package files. The > difference is that it only removes package files that can no longer > be downloaded "Can no longer be downloaded"... Still, weird that the repo contains so many out-of-date versions; I'd have expected them to be removed when they're deprecated. Also, I *think* that's where `apt mark minimize-manual` can clear out some of the cruft that exists post-upgrade. Might be worth a try? rb [Re-directed this to the mailing list, since hopefully there's something of interest to the general community in here and nothing confidential.]
