Subscribe to Librelounge podcast with vlc
In today's video, I do a quick run through on how to subscribe to the Librelouge podcast using the vlc media player.
I am already subscribed to this, so before I paste the link in I remove the existing entry. But this also illustrates that it is just as easy to remove subscriptions.

APG password generator
Debian comes with a useful command line utility called apg for generating passwords, based on criteria set when it is run.
You may need to install with apt install apg
Running just apg produces
ag"OnAub3 (ag-QUOTATION_MARK-On-Aub-THREE)
yissheav-Flas6 (yis-sheav-HYPHEN-Flas-SIX)
rek_OfDot6ly (rek-UNDERSCORE-Of-Dot-SIX-ly)
yorthIs0Ot; (yorth-Is-ZERO-Ot-SEMICOLON)
NapOl{aj6 (Nap-Ol-LEFT_BRACE-aj-SIX)
9Knyhik. (NINE-Kny-hik-PERIOD)
Where as using -m 16 produces a min length of 16 characters
apg -m 16
cryhejIryoatEpBi
DuVospewjopOtsye
veldIc@Ogguckeys
IalNexBeckOdjav1
drureroarAkucEdd
WinquivadLitsUk4
As a good password should be made up of Letters (upper and lower case) Numbers (0-9) Other characters ( !“£$()%^&* )
Then you need to run something like
apg -M sncl -m 16 -n 5
apg -M sncl -m 16 -n 5
EgUrr1slaibzydAr

The program man page also gives more info and an example shell script to help with the process.
man apg
shell script
[begin]----> pwgen.sh
#!/bin/sh
/usr/local/bin/apg -m 8 -x 12 -s
[ end ]----> pwgen.sh

I am using the Deluge bit torrent client to download and stream various free software ISOs. You may find that using this, causes your connection to slow down and other internet operations are slow too. The solution is to pause the download while you do other tasks.
Right click on the torrent you want to pause, and simply select pause, to resume, select resume.

Detexify is a great resource if you want to find a common or perhaps an unusual symbol to insert in to your $\LaTeX$ document.
When you go to the Detexify website [1] you are presented with a box to draw your symbol in. For this context I have the symbols tab selected.
So in the example below I have attempted to draw pi $\pi$. You can see that the website has attempted to find symbols resemble the one I have drawn.
It works for all sorts of things as per the two examples below. You don't need to be that good at drawing the symbol as some can be pretty complex.
This also works the other way. You can enter the name and the website will try and find the corresponding symbol as per below. In this case I am using the classify tab.
In both cases the website will tell you which package you can find this symbol in, and which $LaTeX$ command to use. You can find the package on CTAN [5] for more information on how to use that package. Or you can find the documentation on TeXLive [6].
Hopefully this article is helpful and will help. It is also designed to complement the tutorials at Learn LaTeX [3] which is a new resource.
This article can also complement the upcoming 2020 release of TeX Live [6).

As there are people who are probably stuck at home. due to CoronaVirus. I am sharing some videos from last years Emacsconf and Libreplanet
Libreplanet 2020 took place on the 14th / 15th March and the videos will be published in due course. Plans for the next EmacsConf are underway. Any help, speakers will be appreciated.
If you are able to login to IRC then you can join #emacsconf and #libreplanet respectivley to discuss further.
Everyone is welcome on IRC, however please be patient when asking questions, as not everyone is around, someone will respond in due course.

As I have signed up to various science based courses, mostly with OpenLearn at the moment. I have signed up to the ScienceForums website.
This is a free message forum where you can discuss a wide range of science topics, ask questions, help others. It is quite advanced in places but this suits me fine. You can learn by just reading the questions and answers from different users.
As I am also on IRC then I have joined both physics and chemistry channels on Freenode. This is in order to ask questions or clarification. The physics channel is more useful for the astronomy and astrophysics based courses.
You can join the IRC community via the Freenode Webchat tool.
These websites can really complement e-learning and they provide a way to chat to people who share a real interest in these subjects.
These sites should also be able to complement the e-learning forum that I posted about yesterday.

I am working on a series of $\LaTeX$ flashcards to help people learn the basics.
I am not creating a fully comprehensive set of these. LaTeX has far too many features for this.
What I want to do, is create a set, that just covers the basics:
Hopefully enough for people to get started or for myself to support the teaching of the system.
I feel confident enough to actually try and tech LaTeX, so another reason for these cards would be to help me with this, should I get the opportunity to do so. It is a good idea to prepare for this sort of eventuality.
As LaTeX is aimed at academia, once you have the basics, you can keep going and learn more depending on your usage case. There is a lot of help available too.
Despite it being aimed at academic applications, it can produce very professional looking letters, CVs / Resumes and a whole range of other documents too.

Chemistry Help
I came across this website on the Fediverse as part of a thread on science. I had a look and it appears to be something could really help anyone studying Chemistry
A discussion that mentioned Atomic Orbitals led me to this page on the above website. This site has some nice simulations of topics that are included in the A'level Chemistry Syllabus.
There is also a website with a nice forum on science that I found too. This has a section on Chemistry and then sub forums for Organic, Inorganic and Physical chemistry.
$\LaTeX$ may also be of interest to Chemistry students as you can type set Chemical Formulae etc.
In a sort of related topic, I found a useful site that gives tips on technical writing, I am familiar with some of the ideas presented here, well mostly Constructivism by Jerome Bruner from studying the Supporting Learning in Primary Schools course with the Open University.
I am trying to follow some of this idea when writing instructional blog posts. Provide information on how I do things but put quite a lot of emphasis on the reader actually going away and researching topics. Everyone's system and circumstances are different.
