Great meeting last night!

by Tim Keller

Hey Everybody, The meeting last night was amazing and Kalman showed us was a power emacs users looks like. I've downloaded the video, I'm going to trim it down a bit and upload the video to the wlug youtube account. Once it's uploaded I'll send out the link. 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

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.

Re: Reminder: Virtual Meeting today at 7PM Topic: Emacs awesomeness.

by Chris Thompson

Hello! I'd like to offer a couple notes regarding your upgrade. `apt list --list` may list more than what you've installed explicitly. It will include the packages installed by default in the system (/var/log/installer/initial-status.gz) as well as all the dependencies of packages you've installed. Anyway - that makes for a useful complete list, certainly, but you can generally work from a much smaller list. I think the list you may want comes from `apt-mark showmanual` to list packages you've specifically installed. All this said, https://askubuntu.com/questions/1383951/apt-mark-showmanual-shows-almost-al… seems to indicate that results based on manual installation flags can be problematic before 20.04, so YMMV (though you can exclude from your list based on the initial-status file above as well). While you can do a bash loop and install the packages that way, you can also list a whole bunch on a single run, e.g. `apt install x y z q`. If you are adding >1000 packages, you're likely to run into a limitation doing it that way, but just mentioning - it'd be a little bit quicker (being able to skip identifying packages already installed via others, and running triggers fewer times, etc). Not that it matters all that much, but if you did come up with a list of just 50-100 you need, it's be a reasonable approach. Note that there are changes between the packages in different versions of the OS. Some packages may no longer be available, having been abandoned, and others may be substituted with different packages and so on. While these suggestions will get you close, it may not quite be perfect. If you did opt for an upgrade instead (which works very well in my experience) such changes will often be pointed out to you and/or accommodated for automatically. Finally, don't forget to check for any additional sources you may have added in `/etc/apt/sources*` Regards, Chris On 1/13/22 17:59, gmcaplan--- via WLUG wrote: > Thank you.

"apt list --installed" ... even has chrome on Mint...and other raves

by Doug Mildram

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?

Re: Reminder: Virtual Meeting today at 7PM Topic: Emacs awesomeness.

To your first question, you can get your list of installed packages on Ubuntu by running "apt list --installed" and piping that to a file and copying that off somewhere safe. You'll likely have to strip that file a bit. Then once you've got that file, on your cleanly installed system you can enumerate over that file with a bash for loop and call "apt install *package*" To your second question, I'm sure we've got an R nerd around here..

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. I am running Ubuntu 18.04 LTS. When I update to ver. 20 or 22, I would prefer to do a "clean" re-install, but I have a question. Does that mean I must get a list of all my installed software and re-install them one at a time after I upgrade the OS? If so, is there an easy way for me to get the list? 2. I have been learning to use the software language R. I have a couple of questions and I would like to hear from anyone who has R experience. Thank You.

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!

by Tim Keller

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".

Log4j is a Java logging library. If you're running apache and not using Java, I don't think you need to be concerned.

Bug in the news

by Keith Wright

Are we worried about Log4j / Log4shell (CVE-2021-44228)? I run Apache and never look at the log files. Where are they anyway? Can I configure them out of existence, or just log boring stuff? I don't need remote logging. Can I just firewall packets? -- Keith

I don't know if I will have a jit.si capable computer, but I do know that I will not be in Hudson tonight. I would like to check in. Can I assume that someone will do what someone has done to make what has happened before happen again? Or will the forgotten past be gone forever into the memory hole? -- Keith PS: https://meet.jit.si/WlugMA hereby goes viral!

Hi Everyone, Is the usual meet.jit.si/WlugMA going to be up for far away participants? I've also got 30 seconds of follow up about what I've learned configuring my minimalist wifi repeater. I'll gladly type it out and mail it here if a mixed mode meeting isn't the plan tonight.

Hey Tim, Thanks for the update! This meeting agenda looks exciting! I might get some new inspiration for my Raspberry Pi. Do we have a preference for where we could eat after this meeting? Rail Trail Flatbread seemed to work well last time, maybe we can try Less Than Greater Than? https://www.lessthangreaterthan.com/eat - Josh On Tue, Dec 7, 2021 at 11:50 PM Tim Keller via WLUG <wlug(a)lists.wlug.org> wrote: > 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.

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! Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".
