e-reader recommendations
by Trevor Woerner 21 May '21

21 May '21

I'm looking for recommendations for e-readers. Ideally these recommendations would come in the form of "I have used <the following e-readers> and <this> is the one I like best for <these reasons>" ;-) Nice to have features: - be able to read websites (i.e. surf the web) - be able to mirror a screen from my desktop (or act as another monitor) - be able to take notes

Myanmar military moved early on telecoms
by Warren McPherson 18 May '21

In the months before the Myanmar military’s Feb. 1 coup, telecom and internet service providers were ordered to install intercept spyware that would allow the army to eavesdrop on communications. @f_potkin <https://twitter.com/f_potkin> & @poppymcp https://www.reuters.com/world/asia-pacific/how-myanmars-military-moved-tele…

help ask that eloquence tts be open source.
by Karen Lewellen 17 May '21

17 May '21

Hi folks, Sharing this here because while tts is indeed apart of some adaptive technology tools, its use in devices serving the general populous is expanding as well. There is an effort to ask Microsoft to make the tts engine Eloquence open source. https://www.change.org/p/microsoft-open-source-eti-eloquence while this can be a matter of opinion, Linux tends to suffer a great deal from poor quality, and complex to configure tts options. granted the link does not work well in lower graphical environments. Still, if this resonates, please share and forward, its one of those areas where adaptive technology and broader technology intersect after a fashion. Thanks, Karen

Re: [GTALUG] "DNS Wars"
by D. Hugh Redelmeier 13 May '21

| From: ac via talk <talk(a)gtalug.org> | which project are you speaking of Our project was FreeS/WAN https://freeswan.org/ The intent was to opportunistically encrypt the internet. Authentication is the hardest part to do. We decided that a system's ID would be their IP address and the system would declare its public key in the reverse domain for that IP address. This was cute. Out of date now because almost nobody controls their reverse domain. Eventually our system worked but almost nobody cared enough to deploy it. Free software! The code lives on for VPNs, but that was certainly not the project's goal. | and do you happen to know if the | various/any RIR have any standardised protocols and/or implementations? No. PS: the blog post included an embadded YouTube video. I finally watched it. Very good.

Performance Testing in Chrome
by Nicholas Krause 11 May '21

11 May '21

Greetings, So I recall Kevin asking about it but here are some articles on Chrome DevTools testing tools. It's been there for a few years so really there is no excuse for not running your code through it or the audit feature. Not sure about Firefox's internal testing suite off hand: https://developer.chrome.com/docs/devtools/evaluate-performance/ https://developer.chrome.com/docs/devtools/speed/get-started/ Hopefully this helps, Nick

[GTALUG-Announce] Meeting Today
by hi＠gtalug.org 11 May '21

11 May '21

# Lightning talks and Round Table This is GTALUG's version of an un-conference, a loosely structured short talks emphasizing the informal exchange of information and ideas between participants, rather than following a conventionally structured GTALUG meetings. If you already have a topic in mind please send an email <a href="mailto:speakers@gtalug.org">speakers(a)gtalug.org</a> to be added to the list of scheduled talks. A Round Table Q&A Session is where we take questions from the audience, and the audience discusses and attempts to answer those questions from their own knowledge. It's a great way to meet fellow members of our community and discover the skill sets we each bring to the table. Due to global pandemic we are going to hold this session via video conferencing. We're going to use jitsi for this meeting: Meeting room url: https://jitsi.flamy.ca/GTALUG ## Location Jitsi meeting ## Schedule * 7:30 pm - Meeting and presentation. # Code of Conduct We want a productive happy community that can welcome new ideas, improve every process every year, and foster collaboration between individuals with differing needs, interests and skills. We gain strength from diversity, and actively seek participation from those who enhance it. This code of conduct exists to ensure that diverse groups collaborate to mutual advantage and enjoyment. We will challenge prejudice that could jeopardise the participation of any person in the community. The Code of Conduct governs how we behave in public or in private whenever the Linux community will be judged by our actions. We expect it to be honoured by everyone who represents the community officially or informally, claims affiliation or participates directly. It applies to activities online or offline. We invite anybody to participate. Our community is open. Please read more about the GTALUG Code of Conduct here: https://gtalug.org/about/code-of-conduct/ If you have any questions, comments, or concerns about the GTALUG Code of Conduct please contact the GTALUG Board at board(a)gtalug.org. --- GTALUG Announce mailing list announce(a)gtalug.org https://gtalug.org/mailman/listinfo/announce

Raspberry Pi 4 Starter Kit - Ubiquiti Unifi controller software
by James Knott 10 May '21

10 May '21

I've been considering (because I have way too much time on my hands these days) getting a Raspberry Pi to run my Unifi access point controller software on. I would be doing this with Ubuntu or Raspian Linux. I currently run the controller on my desktop system (openSUSE). I assume a kit like this would be suitable. https://www.canakit.com/raspberry-pi-4-starter-kit.html

War Story: Fedora 33 update silently broke Dovecot (IMAP / POP3 server)
by D. Hugh Redelmeier 10 May '21

10 May '21

Only one of us uses IMAP / POP3. She stopped being able to pick up mail. The message was obscure: Thunderbird reported getting resets from the server. Detective work (leaving out the blind alleys): Look for funny messages in the server log. The right command is arcane: $ journalctl -b _SYSTEMD_UNIT=dovecot.service - -b means "since last boot". Very handy because the log can go back a long time. - _SYSTEMD_UNIT=dovecot.service: only messages about dovecot. Such an intuitive form. It won't work without the .service. It turns out that there is a shortform, -u or --unit=. May 04 14:07:12 redhop-mimosa-com dovecot[977]: config: Warning: please set ssl_dh=</etc/dovecot/dh.pem May 04 14:07:12 redhop-mimosa-com dovecot[977]: config: Warning: You can generate it with: dd if=/var/lib/dovecot/ssl-parameters.dat bs=1 skip=88 | openssl dhparam -inform der > /etc/dovecot/dh.pem May 04 14:07:12 redhop-mimosa-com dovecot[977]: pop3-login: Error: Failed to initialize SSL server context: Can't load DH parameters (ssl_dh setting): error:1408518A:SSL routines:ssl3_ctx_ctrl:dh key too small: user=<>, rip=192.139.70.95, lip=192.139.70.82, session=<jkGQ8oTBnIDAi0Zf> May 04 15:30:28 redhop-mimosa-com dovecot[977]: pop3-login: Error: Failed to initialize SSL server context: Can't load DH parameters (ssl_dh setting): error:1408518A:SSL routines:ssl3_ctx_ctrl:dh key too small: user=<>, rip=192.139.70.95, lip=192.139.70.82, session=<SWRMHIbBmILAi0Zf> The first two messages were almost impossible to read because the were in yellow.

OPTIONAL: /etc/dovecot/dh.pem specified a really weak Diffie-Hellman group. Your should probably strengthen it. I chose ffdhe2048, a weak one (2048 bits) that is still "OK". See: <https://wiki.mozilla.org/Security/Server_Side_TLS#Pre-defined_DHE_groups> You need it in PEM format. First save the old one. Then grab a new one: curl https://ssl-config.mozilla.org/ffdhe2048.txt > /etc/dovecot/dh.pem Then adjust ownership and permissions.
