GameShell: The Hackable Handheld Retro Gaming System
by Scott Elcomb 17 Nov '17

17 Nov '17

Thought this might be of interest to some on the list. "GameShell is the world's first modular, portable game console with a GNU/LINUX embedded operating system. It allows you to play thousands of classic games from Atari, GB, GBA, NES, SNES and many of history’s greatest consoles." It has a modular gameboy-like form factor based on Clockwork Pi (Quad Core A7), 512MB RAM and a 2.7in RGB display. The expected delivery date is in April 2018. The Super Early Bird price is $89.00 (+ $10.00 for shipping to Canada) which is about $50 less than the expected retail price. <https://www.kickstarter.com/projects/954662076/gameshell-redefine-retro-gam…> -- Scott Elcomb @psema4 http://www.pirateparty.ca/

Re: [GTALUG] Fan Control on Linux
by David Thornton 15 Nov '17

15 Nov '17

I find that sometimes different distros have different default supported configs and grok to different degrees various features and hardware. You might try booting various live cds and see what they grok. I loved knoppix to quickly tell how linux friendly a given machine is. Maybe ubuntu or fedora will give you a different view. Live cds often have elaborate complete detection stages... boot and see what chips and config it detects. You might try older versions of distros that have better support for older hardware. Maybe try the version of the live cd that was released one year after the introduction of the laptop.

Dinner pre-meeting?
by Christopher Browne 14 Nov '17

14 Nov '17

Two thoughts present themselves to me... 1. Food Court @ Aura? I hear one of the kiosks has closed, so this option may be on borrowed time; perhaps good to give it a shot before it disappears? 2. Kabul Express we have done several times recently; it's a pretty good idea regardless... -- When confronted by a difficult problem, solve it by reducing it to the question, "How would the Lone Ranger handle this?"

Brand-name desktop recommendation?
by William Park 14 Nov '17

14 Nov '17

I've been asked by few people about which desktop to buy. They are technical enough to swap components, but definitely don't have time to troubleshoot. They have more important things to do. So, I said any brand, new or refurbished, except HP. Things may have changed, and HP may be good now. Which brand would you recommend for desktop computer for business people? -- William Park <opengeometry(a)yahoo.ca>

suggestion: disable fprintd
by D. Hugh Redelmeier 10 Nov '17

10 Nov '17

fprintd(1) handles finger-print recognition for some kind of authentication (logins and who knows what else). At least on my current Fedora and CentOS systems, fprintd is automatically enabled. I don't know about other systems. Most of my systems have no fingerprint hardware, so the only effect is to polute the log. Here's an example: Nov 10 10:30:14 redface-mimosa-com dbus-daemon[637]: dbus[637]: [system] Activating via systemd: service name='net.reactivated.Fprint' unit='fprintd.service' Nov 10 10:30:14 redface-mimosa-com dbus[637]: [system] Activating via systemd: service name='net.reactivated.Fprint' unit='fprintd.service' Nov 10 10:30:14 redface-mimosa-com systemd[1]: Starting Fingerprint Authentication Daemon... Nov 10 10:30:14 redface-mimosa-com dbus[637]: [system] Successfully activated service 'net.reactivated.Fprint' Nov 10 10:30:14 redface-mimosa-com dbus-daemon[637]: dbus[637]: [system] Successfully activated service 'net.reactivated.Fprint' Nov 10 10:30:14 redface-mimosa-com systemd[1]: Started Fingerprint Authentication Daemon. Nov 10 10:30:14 redface-mimosa-com fprintd[28994]: Launching FprintObject Nov 10 10:30:14 redface-mimosa-com fprintd[28994]: D-Bus service launched with name: net.reactivated.Fprint Nov 10 10:30:14 redface-mimosa-com fprintd[28994]: entering main loop Nov 10 10:30:45 redface-mimosa-com fprintd[28994]: No devices in use, exit This happens every once in a while. I don't know what triggers it. Perhaps logins. I have a machine or two with fingerprint hardware. One scary effect is to compromise security -- fingerprints are probably easy to fake. This is only a problem if someone has enrolled in the fprintd system. Otherwise there is neither risk nor reward So: in both cases, it is probably a good idea to: sudo systemctl disable fprintd PS: I think that calling this fprintd instead of fingerprintd is a bit confusing. I used to assume these entries were about printing.

Migrating from MySQL to Postgres
by Myles Braithwaite 👾 07 Nov '17

07 Nov '17

Anyone have some recent first hand experience migrating a MySQL database to Postgres and would like a coffee and cookies in exchange for your case study? I'm working on a project that we are trying to get up and running on Postgres (as we plan on hosting it on Heroku's awesome Postgres instances) and have found that the existing migrate utilities (mysqldump --compatible=postgresql[0], pgloader[1], random sed files, etc) haven't produced the desire results.
