by Tim Keller Feb. 10, 2022

Feb. 10, 2022

Hey Everybody, We've got a virtual meeting tonight, Thursday February 10th. Time: 7pm Location: https://meet.jit.si/WlugMA Presenter: Bill Cattey Topic: Fossil - Github in a box! Long time member Bill Cattey will be giving a talk/demo about Fossil. From the website: https://www2.fossil-scm.org/ <https://www2.fossil-scm.org/> Fossil is a simple, high-reliability, distributed software configuration management system with many integrated advanced features, including things such as bug tracking, wiki, forum, email alerts, chat and tech notes. Many of us are daily users of various SCM systems, such as git, so it'll be great to see what other innovations in the SCM space are out there. I'll be recording this meeting and posting it on our youtube channel. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

clean Linux install while keeping the same packages installed as before
by Chuck Anderson Jan. 16, 2022

Jan. 16, 2022

I'm more familiar with Fedora where I do something like this. It should be possible to do the same in Ubuntu with the appropriate apt-get commands. 1. List all packages with their names only (no versions) on both the old system and newly installed system, assuming the new system is booted and the old system is mounted at /mnt/oldroot. Alternatively, do the first command (without the --root parameter) when booted to the old version and save the file somewhere: rpm -qa --qf='%{name}\n' --root=/mnt/oldroot | sort -u > old-pkglist.txt rpm -qa --qf='%{name}\n' | sort -u > new-pkglist.txt 2. Compare the files and save that output: diff -b -U0 {old,new}-pkglist.txt > old-new-diff.txt grep ^- old-new-diff.txt | cut -c2- > missing-from-new.txt grep ^+ old-new-diff.txt | cut -c2- > only-in-new.txt 3. Now go through the list and install what you want. I usually do this step manually rather than using some automated script, since there are many changes I don't necessarily want, such as shared libraries. All I really care about is applications/commands/utilities. I go through the lists, reading the diff in one window and installing stuff I want in another: dnf install a b c d ... and/or this which installs a package and all of its subpackages except development and debug subpackages. This is great when a package has a bunch of plugins I want: dnf --exclude='*devel*' --exclude='*debug*' install foo-\* ... Or you could curate the list, e.g. edit missing-from-new.txt keeping only the lines you care about, then automatically install everything that is in the curated list: cat missing-from-new-curated.txt | xargs dnf -y install > >> On Thu, Jan 13, 2022 at 3:47 PM gmcaplan--- via WLUG > >> <wlug(a)lists.wlug.org> wrote: > >> > >> I was hoping to attend, but it looks like I will not be able to. > >> I hope it will be recorded because I, too, would like to learn about > >> emacs. > >> Also, I have two questions: > >> 1.

Reminder: Virtual Meeting today at 7PM Topic: Emacs awesomeness.
by Tim Keller Jan. 13, 2022

Jan. 13, 2022

Hey Gang, This is a reminder we've got a meeting today. The presenter is my co-worker, lisp ninja, emacs badass Kalman. Beyond being a emacs wizard, he's also a mainframe guru, a unix/linux guru and is/was deeply involved in the writing/maintaining of the symbolics lisp operating system. Today he's going to show off some of his emacs foo. If you think emacs is an editor of a bygone era when things were more civilized, kalman will likely not change your mind. However, if you want to take your emacs usage to the next level you'll love this talk. If you're totally not into emacs, that's okay, come along for the ride all the same. Expect the usual banter, tangents and fun. We'll also talk about what we'll want todo for the next meeting. See ya at the meeting!

"apt list --installed" ... even has chrome on Mint...and other raves
by Doug Mildram Jan. 13, 2022

Jan. 13, 2022

Hi from doug in Maine ...former WPI netops geek, before that a *NIX admin back to when Vax and Sparc were corporate choices (I guess I've gotten over pining for BSD variants). I supported many emacs geeks (sw/hw developers) then, but never adopted emacs in my pea brain. I guess I preferred vi's stupid modes and ESC and ":" , over CTRL-everything? in emacs. Or maybe I got bit by a macro as a child. For some ancient emacs lore...its security hole Way Back Then is lovingly(ha) mentioned in Clifford Stoll's awesome/fun? book "The Cuckoo's Egg". Just to get root, back then. Access via hopping thru dialup 1200baud modems, and a world where security was off-radar to the engineers owning systems. Even MilNet systems. What fun ! Dumb hacker paradise! One fun line from below: What do you feed a Trojan horse ? Oooh, found a 52-page scan of the book at http://nationalsecurity.gmu.edu/wp-content/uploads/2020/12/Cuckoos-Egg-Read… But as always, I ramble. George: Great question. I "(d)evolved" into a dumb linux Mint user (a great Ubuntu-based distro ..though you gotta choose, Cinnamon,MATE,Xfce. I chose Mate, 20.1 is stable. I forget the why's, but I know it's good with a few beloved windows keyb tricks like ALT-TAB). As a sysadmin responsible for reloading/building systems, I had to fret packages once, .....obviously this was the cat's meow compared to rebuilding from sources and "make". I remember studying our typical < 1000 RedHat packages and feeling like I knew what most of them were. Now I've got > 2000 on Mint, and barely recognize half of them. Today for fun (Thanks Tim), I looked to see... if the one thing I recall needing to install off-package a few years ago = "chrome" showed up in either my sudo logs (nope) or package list. Chrome got into Mint's distros. So my "apt list --installed" output (3mo old desktop load) shows 2028 packages having chosen the "want 3rd party stuff?" install question...so wonderful..so I have both emacsen-common/focal,focal,now 3.0.4 all [installed] and google-chrome-stable/now 91.0.4472.77-1 amd64 [installed,upgradable to: 97.0.4692.71-1] From cmd line, google-chrome (I no longer need on Final side track, I remember years ago saying "amazing...YouTube just works out of box!". Final backtrack...wonder what emacsen-common has, since if I try to launch "emacs" I get Command 'emacs' not found, but can be installed with: sudo apt install e3 # version 1:2.71-2, or sudo apt install emacs-gtk # version 1:26.3+1-1ubuntu2 sudo apt install emacs-lucid # version 1:26.3+1-1ubuntu2 sudo apt install emacs-nox # version 1:26.3+1-1ubuntu2 sudo apt install jove # version 4.17.2.7-1 Pardon my endless rant, hope it doesn't sidetrack today/tonite. I'll be fascinated to see what a recorded session looks like...with chat/comments?

January 13th 2022 Virtual Meeting! Topic: Using Emacs for fun and pro fit.
by Tim Keller Jan. 10, 2022

Jan. 10, 2022

Hey Gang! We've got a meeting on Thursday! In light of the recent surge in Omicron (I managed to get exposed on NYE) I'm going to make this month's meeting virtual. Hopefully next month we can get back to our regularly scheduled in person meetings! Date/Time: January 13th 2022 @ 7pm! Location: Our virtual meeting place: https://meet.jit.si/WlugMA Topic: Using Emacs for fun and pro fit! Presenter: Kalman Reti This meeting's guest speaker is my amazing co-worker Kalman Reti. If you've never used emacs or used it for years, you'll love this talk. If you hate emacs, well, there's nothing to be said other than to come along and jeer. Kalman is many things, but one of them is a power user of emacs. He's agreed to show off some of his emacs kung fu. In this talk you'll learn some emacs history, likely some lisp and definitely some tricks. Beyond being an emacs guru, he's also a fountain of knowledge of all things unix/linux and beyond! Along the way, I'm sure we'll engage in our usual banter, side tracks and fun. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Dec. 15, 2021

Hey Everybody, We've got a meeting this Thursday at the Hudson Public Library! Topic: Jail breaking that Wii you've got laying around to run Linux! Then I'm sure it'll get even more interesting! I'd like to brain storm about topics we'd like to talk about next year! Ideas that have been talked about: 1. Pi-hole. What it is, how it works and why you want one! 2. Raspberry Pi clusters.. How to build one and what would you do with one? 3. Ham radio and Linux. I'll have snacks and refreshments on hand, we'll head off to dinner afterwards!

Reminder: November WLUG Meeting at the Hudson Public Library! Topic: Intel Management Engine.
by Tim Keller Nov. 19, 2021

Nov. 19, 2021

Hey Everybody, We've got a meeting this Thursday November 18th, 2021 at 7pm - 8:30pm at the Hudson Public Library! Firstly, a big shout out to Joshua Stone for making the reservation at the Hudson Public Library. Secondly, the meeting will also be online at our usual Jitsi location for people who can't make it in person. https://meet.jit.si/WlugMA The topic we'll be discussing at the meeting is the Intel Management Engine technology buried in every Intel CPU. This technology includes a version of Minix running on a separate core inside your CPU you don't control. Moreover, with the right software, changes to your machine can be made remotely, even when the system is powered off (but connected to power). As with all this stuff, of course since the whole thing is cooked into the firmware, it's full of security flaws, etc.. We'll talk about those flaws and how to disable it! We'll also likely touch on the Tesla Dojo D1 processing unit. They've made some claims that I've posted to the mailing list. Logan did some digging and it turns out their claims are not as blow your mind as would be first interpreted. The Hudson Public Library does allow food and drink, so I will bring the usual pretzels and snacks. Afterwards we will be going to Rail Trail Flatbread <https://railtrailflatbread.com/>for dinner. Toss me a line privately if you'll be attending so we've got an idea of how many people will be going out for dinner. I look forward to seeing you there! Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Use same hostname internally and externally
by brad Nov. 15, 2021

Nov. 15, 2021

All, To quickly summarize my problem/question, I’d like to host a nextcloud server at my house and be able to access it with the same hostname whether I’m home or away. I own a domain, let’s call it example.com. Its main DNS record points to a node at digital oceans. However I’d like to host a sub-domain at my house, let’s call it home.example.com. Currently home.example.com resolves to a routable IP address at my house. - When I’m on the road, I’d like to be able to connect to https://home.example.come - When I’m home, I’d like to be able to connect to https://home.example.com. The above works on a well-behaved desktop receiving dns servers via dhcp. Specifically, I have setup local dns to resolve home.example.com to 192.168.1.1. Searching this topic has taught me that this method is called Split-DNS. However android and iOS do not appear to honer my local dns server — I’m not sure why — so they resolve the address to a routable IP and connect from within the private 192.168.1.0 subnet. My firewall sees this and drops it b/c it is a non-routable IP address connecting to the external interface. (I got this info by running tcpdump and watching traffic). Has anyone attempted something similar? Is there something I’m overlooking? (Probably) My goal is to not do special configurations on enduser devices. Thanks, — brad

by Joshua Stone Nov. 15, 2021

Nov. 15, 2021

Hey all, I'm posting to confirm that the venue for our upcoming in-person meeting at 7PM will be held at the Hudson Public Library! We may also want to look into eating options after the meeting, many of which are on Main Street: https://www.discoverhudson.org/taste/ My vote goes to the Rail Trail Flatbread which is close to the library and has some incredibly tasty menu items! And speaking of main streets, I'm happy to announce that Hudson has become a semi-finalist for the Main Street Contest! https://mainstreetcontest.com https://mainstreetcontest.com/profile/102 I think it's awesome that the town has seen so much growth since we moved here and gives us a sense of community. I'm excited to see where it'll go! - Josh

Nov. 11, 2021

Hey Gang, My birthday is on the 11th and the family is taking me out for dinner. We'll have the meeting on the 18th instead! I've got some ideas for topics, but if someone has a burning desire to talk about something, let me know! Otherwise I think I'll show off my experiments with TrueNAS scale.

Sorry for this intrusive method of finding someone, but I saw Andy Stewart at the NearFest this past Friday, and thinking that I had his email address (and I did), I am having trouble with contacting mval.net, his mail domain. Does anyone have an alternative address for him, of if Andy reads this can you either fix your server or give me a working email? Thanks, md

Open Source Game Achievements Article
by Dennis Payne Sept. 30, 2021

Sept. 30, 2021

Fedora Magazine has published my article on open source game achievements. https://fedoramagazine.org/open-source-game-achievements/ I just got Alchemy Quest, Anagramarama, and Inertia Blast add to Fedora.

Inertia Blast
by Dennis Payne Sept. 10, 2021

Sept. 10, 2021

Thrust is an old C64 game. I never played the original but enjoyed an svgalib version a long time ago. Svgalib was used for games when people didn't have machines that could reasonably run X. It requires root to run and can't run under X so it isn't something people do now for the most part. The version I played now has an X version but it requires pseudo color so it is not usable. I updated the code to use SDL. I replaced some images that seemed to have been copied from the original. I renamed the game to Inertia Blast. Of course this included adding Gamerzilla support but it is minimal at the moment with only two achievements. http://identicalsoftware.com/inertiablast/ -- Dennis Payne dulsi(a)identicalsoftware.com https://mastodon.gamedev.place/@dulsi
