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

by Tim Keller

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

January 13th 2022 Virtual Meeting! Topic: Using Emacs for fun and pro fit.

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".

I’m a big fan of RegEx golf https://alf.nu/RegexGolf, and there’s more great stuff at Alf.nu as well.

Here's a good read on log4shell... https://www.lunasec.io/docs/blog/log4j-zero-day-mitigation-guide/ and an ongoing list of vendor responses.... https://gist.github.com/SwitHak/b66db3a06c2955a9cb71a8718970c592 It's bound to bring us 'joy' in the holiday season and beyond! Joe

This might be able to find out if your system has any traces of log4j installed: sudo find / -name '*log4j*' -print If that doesn't output anything, you are most likely safe. ________________________________ From: Chris Thompson via WLUG <wlug(a)lists.wlug.org> Sent: Wednesday, December 15, 2021 3:40 PM To: wlug(a)lists.wlug.org <wlug(a)lists.wlug.org> Cc: Chris Thompson <wolcen(a)riseup.net> Subject: [WLUG] Re: Bug in the news httpd does not use log4j. solr, on the other hand, normally does. ...and Minecraft, if that applies to your server :P ~Chris On 12/15/21 15:26, Keith Wright via WLUG wrote: > Michael Voorhis <mvoorhis(a)mcvau.net> writes: > >> Log4j is a Java logging library. >> If you're running apache and not using Java, >> I don't think you need to be concerned. >> >> See here... >> >> https://en.wikipedia.org/wiki/Log4Shell > Interesting link, thanks for that. > > I don't use Java, but is Apache using it without my knowledge? > > NB: I am a bear of little brain. -- Pooh > I can't.

I don't use Java, but is Apache using it without my knowledge? NB: I am a bear of little brain. -- Pooh I can't.

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