Fwd: Re: firefox font weirdness?
by Hartmut W Sager 13 Mar '24

Furthermore, here's my Firefox settings "fonts, advanced ...": Of those settings, the only one that might have been me is the Times New Roman for serif(ied) font.

Date: Friday, March 08, 2024 02:10 Oooh, ouch! I'm very sensitive to crap like that, and it has happened to me a few times over the years. Right now, I'm on (Win 10) Firefox ver 123.0 (nothing after the 0), but it wants to update me, which, in view of what you said, I will try to hold off. Besides, I have about 40 open tabs with unfinished business. I can also look up my Firefox settings on items of specific interest to you, since you can't view pre-123.0.2 settings. My Firefox default font is Times New Roman 16. (Hmmm, did I do that some time ago? - I don't recall, and I typically use Verdana 10 or 12 whenever I don't like someone else's font choice.) I haven't yet looked into all the "inspector" stuff you quoted. Hartmut On Fri 08 Mar 2024 at 01:52:09 -06:00, Trevor Cordes <trevor(a)tecnopolis.ca> wrote: > Has anyone noticed that newer/est(?)

firefox font weirdness?
by Trevor Cordes 08 Mar '24

08 Mar '24

Has anyone noticed that newer/est(?) Firefox 123 (123.0.2) suddenly made the fonts all weird in some cases? Like the default fonts were changed, and/or entire relaed css definitions like line height? I have a simple web page with no css set and no font settings and it suddenly looks very different, with the font just "wrong" and line height set very strangely. If I click webdev inspector it doesn't tell me what font it's using, so it must be the firefox default. Settings says that's bitstream vera serif / vera sans. I really have no way to see what the default was before? Worse, a forum site I frequent suddenly has the textarea box go mental on the font and line height. But only in firefox, and never before v123. The inspector shows font-family: DejaVu Sans Mono,Monaco,Consolas,monospace font: 83.33%/150% Segoe UI,Helvetica Neue,Nimubs Sans L,Arial,Liberation Sans,sans-serif (I have no clue what the % prefixes are for in the font setting.) Inspector says all the heights and related font- stuff is normal. The font looks like a decent sans, but in no way is it monospaced as the family indicates! If I type in numbers, they come out lighter gray (vs the normal black text), and line height is normal. But if I type a single letter on a line, all of a sudden that line gets about half-line-height padding above and below itself! I can send a screenshot if desired. In Chromium all of this stuff works and looks normal (as firefox used to). And the mono font really is mono on that forum textarea. Is anyone else have font weirdness with firefox 123? Anything I can try as a fix? Maybe I'm missing some fonts? The only font-y thing I've done in the last year is try to get that new Monaspace stuff installed and working in gnome-terminal, but even that hasn't been toyed with in over a month. If someone has firefox <122 installed still, what are the default fonts in the settings? Thanks!

Chrome blows up the net?
by Trevor Cordes 08 Mar '24

08 Mar '24

So I hit the computer for the first time today and there's not the usual 2-5 Fedora sec update notices, but 356. That's a first. So Google Chrome has a really bad zero-day High CVE-2024-1938: Type Confusion in V8 High CVE-2024-1939: Type Confusion in V8 And these 356 are all this bug. This is very interesting because these just seem like random packages... how can they all have this bug? So it looks like the Chrome stuff got into JDK stuff, and the JDK stuff got into 300+ other things (uh, what?). Strangely, I don't see notices for Chromium or webkit libraries... unless they are coming next. Y'all started using firejail to wrap your Chrome/Chromium in after the Feb MUUG presentation, right?? ?? Add some more height to the histogram I posted of Chrome CVEs... Google: leading the pack. Luckily I mostly use Firefox! The info on these CVEs is currently very limited. If someone has some juicier info on the hole, let us know. CVE-2024-1938 Type Confusion in V8 in Google Chrome prior to 122.0.6261.94 allowed a remote attacker to potentially exploit object corruption via a crafted HTML page. (Chromium security severity: High) CVE-2024-1939 Type Confusion in V8 in Google Chrome prior to 122.0.6261.94 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

Reminder: MUUG Meeting, Tonight, Mar 5, 7:30pm (Date Change, In-person/Hybrid Meeting) -- Fluentd
by Gilbert Detillieux 05 Mar '24

05 Mar '24

A reminder that the MUUG meeting will be this evening, both in person and online... The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting IN PERSON, on Tuesday, March 5th, at 7:30pm. Yes, that's a week early, i.e. the FIRST Tuesday of the month... Fluentd Alberto Abrao will present and demo fluentd. According to their website, "Fluentd is an open source data collector for unified logging layer." Fluentd is lightweight enough that you can host it on a Raspberry Pi or similar low-end device. The presentation will walk us through the configuration of a machine that will serve as a "log aggregator," and a couple of others that will send their logs to it. All logs will stay in plain text, as the "Gods of UNIX" intended. Where to find the Meeting: Fortress Software Inc., 350 Keewatin St -- Unit #2 We have a new in-person meeting location now! Brad Vokey has graciously let us use his work office for our next in-person meeting. The meeting room will be open by 7:00 pm, with the actual meeting starting at 7:30 pm. If driving, enter the lot using the most north east entrance and drive around to the south west corner of the building (see route in map detail on poster linked below). You can use any of the free, ample, and safe parking spots that say "reserved" in front of units #1 through #4 before entering unit #2. Bus stops #30814 and #30880 (route 77) are only 150 meters away. The last bus leaves for Polo Park at 10:15 pm and for Garden City at 10:31 pm. Logan Ave. bus routes #19, #26, and #27 are a 600 meter (8 minute) walk to the south. For those unable or preferring not to attend in person, the meeting will also be available online, using BBB as usual. Stay tuned to our muug.ca home page for the official URL, which will be made available about a half hour before the meeting starts. (Reload the page if you don't see the link, or if there are issues with connecting.) *Date Change* Please note the change in meeting date for this month, and for the rest of the current year: We are now meeting on the first Tuesday of each month. The group now holds its meetings at 7:30pm on the *first* Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend.

Wifi recommendations
by Kevin McGregor 28 Feb '24

28 Feb '24

I have a Netgear Orbi mesh (1 base + 1 satellite) in my house. They're about 6 years old and don't support Wifi 6 (802.11ax?). I've noticed that in my basement it works pretty well, but upstairs the effective data rate drops off VERY quickly when I move away from the router (satellite). I figure this is because of the large number of wifi routers in my neighbourhood competing for the same bandwidth. Would upgrading to a Wifi 6-capable router help? Any other suggestions?

Cat 6 cable
by Kevin McGregor 27 Feb '24

27 Feb '24

What's the going price for a 1000' box of Cat 6 cable? Is there a good place to buy it in Winnipeg, or order online? I'm thinking of running some network cable in my house, most likely 1 GbE. I had previously used Cat 5E. Should I stick with that instead of 6?

Getting disk sizes of mountpoints
by Kevin McGregor 22 Feb '24

22 Feb '24

With 'lsblk' I can get something like this: NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 20G 0 disk └─sda1 8:1 0 20G 0 part ├─vg0-root 253:0 0 15G 0 lvm / └─vg0-var 253:1 0 5G 0 lvm /var sdb 8:16 0 100G 0 disk └─sdb1 8:17 0 100G 0 part └─vg1-data 253:2 0 100G 0 lvm /mnt/data sr0 11:0 1 1024M 0 rom What I'm looking for is output like: / 15G /var 5G /mnt/data 100G So I just want the size of the block devices which are actually mounted. I'm wondering what is the most reliable way to produce the second output. I can just grep for 'lvm', but I can't guarantee the mounts are all LVM type. I can grep for ' 253:', but is the 253 going to be reliable? What does 253 even mean? >From https://www.kernel.org/doc/html/latest/admin-guide/devices.html : 240-254 block LOCAL/EXPERIMENTAL USE Allocated for local/experimental use. For devices not assigned official numbers, these ranges should be used in order to avoid conflicting with future assignments. ... which isn't encouraging. Is that list outdated? grep for '/'s?

Does anyone know of a Winnipeg-based group for SREs (Site Reliability Engineers)? Does anyone know any SREs in Winnipeg?
