05 Apr '22

The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting online, on Tuesday, April 12th, at 7:30pm: Cloud-init Kevin McGregor will provide an overview of cloud-init, a widely-supported way to initialize instances of cloud-aware distros (i.e. pretty much all of them!) on your public, private or home cloud. This will once again be an online meeting. 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.) The group holds its meetings at 7:30pm on the second 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.

Skullspace Hax festival April 1-3 may interest MUUG members
by Mark Jenkins 01 Apr '22

01 Apr '22

Hey MUUG folks, My latest project has been organizing an event at our local hackerspace Skullspace this upcoming weekend (with online participation options as well) It's a weekend festival that includes a movie night, talks, a DJ evening and a chill out day with exhibits and gaming. https://hax.skullspace.ca I don't have any talks that are about unix-like systems specifically, but I am happy to report that I will be running my live streams using GNU/Linux and obs-studio. One interesting problem I solved recently was figuring out how to incorporate live footage from a Go Pro Hero 9 into my live stream. My recent notes on this are a github gist at https://is.gd/kgCSHA --------- Another free/libre/open-source software angle is that I'm planning to host a game of Pioneers, a computer clone of the board game Catan. (one of the elements with remote participation) The Pioneers client and server are packed by many GNU/Linux distros. So, again, more info at https://hax.skullspace.ca Our building door may or may not be locked at certain times. If it's open, come up 1.5 flights of stairs to the 2nd floor. If the building door is closed, push the small white buzzer labeled "sksp" and wait for someone to come down. Mark Jenkins

It's out of Regina, it's not too early in the day, and it's free! I can think of people in industry, infrastructure and manufacturing who I want to send this to. Topics covered include new US regulations, working with ancient machinery and lost source code, and a Log4j case study. On GoToWebinar. https://www.meetup.com/Regina-Cyber-Security-for-Control-Systems/events/284… Vicki -- VickiNemethWriter.com

Reminder: MUUG Online Meeting, Tonight, Mar 8, 7:30pm -- Serverless Web Sites with AWS, tldr
by Gilbert E. Detillieux 08 Mar '22

08 Mar '22

A reminder that the MUUG online meeting will be on BBB this evening... The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting online, on Tuesday, March 8th, at 7:30pm: Serverless Web Sites with AWS What? How do you host websites without a server? Impossible? Join the meeting to find out! Wyatt Zacharias will take us through using AWS to set up so-called "serverless" web sites. RTFM: tldr(1) - a simpler alternative to man(1) This month, Brad Vokey will give us a quick demo of the tldr command that he introduced to us in the December 2021 newsletter (last page). tldr is a Python command-line client to the TLDR pages. The TLDR pages is a free and open-source collaborative software documentation project that aims to be a simpler, more approachable complement to traditional man pages. It's a collection of community-maintained help pages that covers command-line utilities and other computer programs. This will once again be an online meeting. 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.) The group holds its meetings at 7:30pm on the second Tuesday of every month from September to June.

Re: [RndTbl] Old MUUG server up for grabs! ($$$)
by Adam Thompson 03 Mar '22

03 Mar '22

The high bid on the server was $719. If you believe you submitted a higher bid than that, that I’m ignoring or didn’t receive, let board@ know ASAP. -Adam From: Adam Thompson On Behalf Of athompso(a)muug.ca Sent: Tuesday, February 15, 2022 11:51 PM To: MUUG Roundtable <roundtable(a)muug.ca>; MUUG Announce <muug-announce(a)muug.ca> Cc: 'athompso(a)muug.ca' <athompso(a)muug.ca> Subject: Old MUUG server up for grabs! ($$$) We’re getting rid of the old server! It’s up for auction, to MUUG members in good standing only. We’re taking bids for the rest of the month by email. Emailed bids must be received by me no later than Monday 2022-Feb-28 23:59:59 to be considered eligible. We’re doing this as a “blind auction<https://en.wikipedia.org/wiki/First-price_sealed-bid_auction>”, where everyone submits their bid to me (Adam Thompson), and at the end of the bidding period, I’ll contact the highest bidder. If they’re unable to follow through for any reason, it goes to the second-highest bidder, and so on. We cannot issue a receipt for tax purposes. The MUUG board (excluding board members who entered bids themselves) shall be the only, and final, avenue of appeal for anything related to this auction. Since we already know some of the board is planning to bid, and I am not, send your bids to me directly: athompso(a)muug.ca<mailto:athompso@muug.ca> (or my usual address, they both wind up in the same place), and not to board@. Please provide name, email, phone#, and dollar amount. If you don’t receive a confirmation from me within a few days, post to roundtable letting me know something’s wrong. And/or try a different email provider.

by Ihor Jakowec 26 Feb '22

26 Feb '22

How do I bid. And more importantly for you, how do I pay. Is it noisy? Would you accept bids here. How about $100.05. my regards, Ihor Jakowec

Re: [RndTbl] [Muug] Old MUUG server up for grabs! ($$$)
by eh＠eduardhiebert.com 22 Feb '22

As somewhat of a policy wonk other than the non-existent means of a sealed bid until the close of bidding, I would like to express my kudos to the MUUG board in coming up with a good process involving minimal bureaucracy in liquidating retired equipment AND leaving it open to board members as well to be part of the bidding process. The one variant I suggest to avoid even the possibility of an appeal is that MUUG publish the winning bid dollar amount, or any further cascading amount, should any come into play. As each bidder knows their own number, this would eliminate nearly all possibility of appeals except for the error of an oversight or typo concerning the tally sheet of all bids. My further thanks to Adam as this does not come without a further voluntary time commitment. Eduard On 2022-02-15 22:58, MUUG meeting announcements wrote: > We’re getting rid of the old server!
