I submitted a proposal for a #LibrePlanet2021 session. I did not speak last year because of worries around COVID-19, and this year I'll almost certainly be attending remotely. The @fsf will be considering both remote and in-person proposals, should in-person be an option.

Consider submitting your own proposal! For more information, see:

Want to render plain text in a more interesting (or obnoxious) way? `cowsay` and `figlet` offer good fun.

Bonus points if you can actually use them in a context that is productive and useful. You've almost certainly seen figlet's output before in a number of different contexts, such as motds and headings.

I work mostly from the command line, but sometimes I need to open an external GUI program to do something visual.

Since I don't often use those programs, I may forget what I installed to open a particular file.

The command `xdg-open` from xdg-utils will try to DTRT and invoke the right program for you. You can query and change preferred programs using `xdg-mime`. And this works without a desktop environment (e.g. I use i3wm).

My last post on free software I use mentioned a substitute for using search engines for word definitions.

Another common use of search engines is unit conversions (e.g. 3 miles to km). For that and more, I use GNU units (https://www.gnu.org/software/units/).

I can't do any justice to this program with the number of characters I have left, so please, check it out; you won't be disappointed.

One of my favorite command line tools is `dict`---a dictionary and thesaurus. I use it multiple times a week. If you find yourself prefixing search queries with `define:`, this tool is for you.

If you install `dictd`, you also get the freedom and privacy of answering your own queries on a system you control, without the need for Internet access.

@sir It's also worth noting that, in the US, this is a right protected by the NLRA (National Labor Relations Act).

@strypey If you can trust that the people in the room are not bad actors (that they won't publish your message elsewhere, thereby circumventing the encryption), then encrypted history allows you to have a conversation relative to the current userlist. E.g. you can badmouth your boss if the channel has only trusted coworkers. ;)

So if your district happens to be involved in these discussions, be sure to voice dissent in Board meetings or wherever you need to, because once the decision is made, you're stuck with it for a very long time.

@strypey The unfortunate reality is that, by the time that schools have made those decisions; structured their systems around a particular platform; purchased hundreds of thousands of dollars worth of hardware; trained employees on it; etc, it's extremely difficult to change, especially if you're one of the only voices. It may even be impossible in any near term given restrictions on taxpayer funds (it's very costly to change).

Another tool I often use at the end of a pipeline for data visualization is gnuplot (http://www.gnuplot.info/). It supports far more sophisticated graphs than I can ever hope to have use for.

I typically prototype using its interactive prompt, and then either write that to a static script, or generate the script and pipe it. It's an essential tool for command line data processing.

I use Graphviz (https://graphviz.org/) for more things than I could possibly recall. It is one of my core tools for data visualization for a wide range of data, and it's quite easy to use and generate graphs for.

If graphs get so large that the visualizations are no longer possible to grok, or if querying is needed, I may opt for a graph database instead.

The graph description language DOT (https://en.wikipedia.org/wiki/DOT_(graph_description_language)) is simple enough to be useful for mapping out thoughts too.

To adjust the color temperature of my screen, I use redshift (CLI). I use an i3 keybinding to perform adjustments manually rather than relying on the time of day, since lighting varies wildly depending on the room I'm in, whether we have lights on, weather, etc.

I also sometimes use it to reduce strain on my eyes instead of reducing screen brightness because my X200's monitor makes a high-pitched whine when I reduce brightness even the slightest.

...I get some intense nostalgia looking at some of those screenshots.

Speaking of compositing, I remember back in the day I bought a new video card just so I could have smooth effects with Compiz and Beryl, like a cube desktop; painting fire; rain; wobbly windows; etc.

And now I have no effects to speak of.

(Compiz Extras + Beryl later merged into Compiz Fusion, which is now just Compiz.)

Yesterday I mentioned that I use i3 as my window manager. Unlike some others, i3 does is not a compositing WM---it doesn't provide double buffering.

Consequently, I may notice tearing when scrolling in my web browser, switching workspaces, or looking at fast-scrolling terminal output.

To fix that, I use compton. It provides other features, like shadows and transparency, that don't make sense for me in a tiling WM. I just use the `-CGb` options.
