JMAP Revamped jmap.io Website
by Hartmut W Sager 22 Apr '26

22 Apr '26

As many of you have noticed, I have been very supportive of the JMAP initiative, an IETF standard intended to replace IMAP and SMTP, and ultimately CalDAV and CardDAV too. Well, they just announced a revamped Website, still located at: https://jmap.io/ Hartmut ----- Original message ----- From: Neil Jenkins <neilj=40fastmailteam.com(a)dmarc.ietf.org> To: IETF JMAP Mailing List <jmap(a)ietf.org> Subject: [JMAP] Revamped jmap.io website Date: Monday, April 20, 2026 21:51 Hi all, We've just rolled out a major revamp of the jmap.io website. Some highlights: • Much improved design, now also responsive for mobile devices, and with dark mode support. • All the JMAP RFCs hosted in one place, formatted nicely and easy to link to any line in the spec. • New "Why JMAP" page with the case for switching. Hopefully this helps people discover and learn about JMAP, and as a useful reference guide. Cheers, Neil.

Re: OpenBSD CDs and DVDs

Sorry for the noise. Just replying to this request since his email address doesn’t seem to work (cl(a)foo.tinfoilhat.ca) Chris, I ended up having to leave a lot of books and all the OpenBSD CDs and DVDs at my old house which has since been sold. So unfortunately I am not able to get that for you.

Mailing list changes -- please read, impacts how you use the list!
by Trevor Cordes 18 Apr '26

18 Apr '26

We were made aware of some issues with inadvertent unsubs from the mailing lists. To fix this we were forced to go full on with DMARC, DKIM, SPF, ARC, the whole enchilada. This will impact you, the user, in a very important way: the From: address in the header of emails you get from the mailing lists will now be from @muug.ca. Previously, they would be From: the actual person who sent the email to the list. (Look at the From: header and Reply-To: header of this email to get an idea of the change.) This will impact what happens when you press REPLY (and related buttons) in your MUA (your Outlook, gmail, thunderbird, etc). What exactly happens is up to your MUA. But now you have to be extra careful that you aren't sending a private/personal response (meant for the human sender) to the mailing list. Always check your To: and Cc: headers before you hit send! The opposite may happen too, a reply you want to go to the list may just go to the sender! Click your reply, reply-all and reply-sender buttons now to get a feel for what will happen (then hit cancel!). On my box/MUA, the reply-sender button is now useless (completely backwards). YMMV If you're interested in the full technical spiel feel free to ask me at the next meeting's roundtable! :-) If something doesn't work, email (right away!) the list, or email me directly with MUUG in the subject. (See this email's reply-to header.)

noscript brainstorm
by Trevor Cordes 18 Apr '26

18 Apr '26

I'm very close to switching from a default-deny to a default-allow paradigm in the browser extension NoScript. It's just gotten way too much of a pain to keep checking & allowing things (especially on mobile with its clunky interfaces). So my goal now is to create the best always-untrusted/block list of the worst/easiest offenders and then switch to default-allow. I have the usual suspects like doubleclick and various google domains, et al. I was wondering if anyone else would care to share the domains they always block for js in their browsers? I'd love a good standard list of what to block. Stuff that doesn't really break anything but limits the scripts running from trackers/ad-ers. Thanks!

shortened cert expiries
by Trevor Cordes 13 Apr '26

13 Apr '26

Anyone interested, first read the MUUG newsletter article on certs last month: https://muug.ca/pub/muuglines/pdf/muug2604.pdf page 2 As a followup, it gets worse! I just discovered that if you want to impelment ACME to automate cert renewals with a for-pay cert company like Digitcert (who after buying tons of people up is a massive share of the market) you have to register with their "enterprise" system. If you do that and migrate your certs then you are converting to a direct sales model and can no longer buy from a reseller. This is important for me as I'm the reseller! So a by-product of this move is they just killed the reseller market, and undoubtedly not by accident. Ya, I get it, but this doesn't just hurt the reseller, it hurts the customer: because in many cases I was able to discount the cert vs retail price. Now you'll pay whatever retail price digicert says. It looks like *my* upstream reseller (opensrs) could possibly implement ACME, but they haven't yet, and claim to be blindsided by these expiry changes, so I doubt can implement it anytime soon. Apparently they can, since select (few) other resellers are implementing ACME... but who knows how all this would work. In any event, all the decisions are being made *now* because as of a month ago certs with the short expiries are needing to be renewed, and needing automation because I'm not updating everyone's cert many times a year (even 2). Unless someone says "ACME is coming soon!" I'll have to tell everyone to use Let's Encrypt and sell nothing but my time from now on. Which is fine, but a vast departure from how I've sold/handled certs for 25 years, and impacts the relationship I have with my customers. In this space, absolutely no one likes change or having to think about "new things". It needs to Just Work(tm). Literally no one cares about it unless it breaks, and the costs were so miniscule to companies that even having to explain the new options is a waste of everyone's time. All for, what, exactly? CRL and quantum... ya, right.

is zscaler9 a thing here?
by Trevor Cordes 11 Apr '26

11 Apr '26

Does anyone know of zscaler9 and its products? We are getting a large number of DNS lookup hits on our DNS server from zscaler9 sattelites / proxies. They appear to be a security provider who sits MITM to cleanse traffic for corps? Are there users of this product in MB, or Canada? Is this a big thing or a little thing? Can anything justify large quantities of DNS queries from them from all over the world? It looks like they intercept DNS and spoof with their own stuff, but if their proxies are caching shouldn't they only produce a sane/normal amount of hits?

A reminder that the MUUG meeting is happening, both in-person and online, this evening... The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting IN PERSON, on Tuesday, April 7th, at 7:30pm. Yes, that's the FIRST Tuesday of the month... Audio Files for the Audiophile In April’s presentation, Reb James will delve into the nuances of ripping audio CDs into a digital format. Playing on various devices is desirable; more importantly, archiving physical media into files for multiple backups. Discs can be damaged or lost. First is a discussion of suitable lossy/lossless audio formats. Reb tested available codecs in July 2024 with a new setup from previous types. Finally, the 7-step process that transforms audio into better quality than the original. Join us at the April meeting! Where to find the Meeting: **NOTE NEW LOCATION** Winnipeg Senior Citizens Radio Club, 598 St. Mary's Road, 2nd Floor WSC is located at 598 St. Mary's Road, 2nd Floor, a block South from the St. Mary's / St. Anne's fork, on the West side beside the Miller's Meats. It's in the old fire hall, so you really can't miss it! Look for the red door. There are a limited number of parking spaces for WSC around the building. If you arrive early you'll probably snag one. If not, there is parking available on the nearby streets, such as Mager Dr, or the streets off of St. Mary's such as Blenheim or Clonard Ave. Be careful not to park in nearby private parking lots unless otherwise indicated. There is no elevator, so attendees will have to be able to climb a flight of stairs. Apologies to anyone requiring accessibility. *Please Remove Your Footwear!* To keep the carpets clean and dry, please remove your outdoor footwear at the top of the stairs. Feel free to bring a pair of indoor shoes, sandals, or Crocs to use indoors. *Entry Log Book:* To support WSC operations, we ask all guests to sign the log book provided by WSC as you enter the meeting space. Online Meeting Option: For those unable or preferring not to attend in person, the meeting will also be available online, using BBB as usual.

Roundtable
by Tait Palsson 01 Apr '26

01 Apr '26

Hello MUUG Roundtable, Is it just me or is it impossible to burn a .iso to an optical disc? I have tried with dd, various iso writers on various distributions but these either grey out or do not list the target device, and with multiple pieces of hardware. I am always met with an error that the media is read-only when the disc drive is read and write. I also tried /dev/sr0 and its alias /dev/cdrom but nothing different happened. An internet search tells me that special software like wodim, growisofs, or Brasero could be needed. Why and is this just me? If dd did work I imagine that I could use bs= to bring down the write speed and improve accuracy. Sincerely, Tait

One of my dvd players requires ISO9660 filesystem for mp3 disks.

The app Lplex had a good description of process. Upsampling to 48khz required, particular with codecs. More effort than a simple audio cd. Thanks for response!
