Trying A Minimum Working Example

When you make assertions in a channel like the Ubuntu Podcast's Telegram chatter channel they sometimes have to be backed up. Recently I made reference to how you could utilize Markdown within a LaTeX document. I should take a moment to discuss a way to use LuaLaTeX to make your Markdown documents look nice. We're going to build a "Minimum Working Example" to illustrate things.

First, I will refer to a package on the Comprehensive TeX Archive Network simply named markdown. That handles processing Markdown input. In its documentation you find that you can actually input a separate Markdown-formatted file into the macros provided which will convert them into appropriate LaTeX code and add that programmatically into your document. LaTeX is a Turing-complete programming language after all.

Using the basic default article class and bearing in mind that I am based in the United States of America, we can have something like this:

\setmainfont{Liberation Serif}


Taking that example line by line we mostly have a preamble and a very short document. First we declare the document's class as "article" and pass the global options of wanting 12 point type and since I am in the USA I want to use Letter paper. Next we load the hypertext support package hyperref. We then load the smaller support package xurl which allows for URLs to break at any alphanumeric character in text. Our main player markdown then gets loaded. Since we're using LuaLaTex to compile the document we then load the fontspec package to allow using any OpenType fonts. Liberation Serif is a font that ships in the basic install for any Ubuntu flavour so we'll choose that. While we could have done something obscure like use Public Sans we'll stick to basics today.

You can save that file locally as mwe.tex. Now, we need our Markdown file. We'll keep it simple with this:

We have a **great** help system at [AskUbuntu](  

Save that single line as You'll want to have both files in the same directory. From there you can then appropriately invoke LuaLaTeX with shell escape enabled and you'll get a file with the line typeset and the link showing as a footnote. The link in the footnote will be clickable.

This is a very minimal example. You can modify what is essentially a driver file for LaTeX to process through your Markdown creations to make them look nice. Pandoc does something similar but this allows a bit closer ability to fiddle with settings. This can be included in automation chains to make pretty print output fairly readily with contemporary web stylings.

For further introduction to LaTeX, the guide that really helped me is "A short introduction to LaTeX2e" mainted by Tobias Oetiker which you can find in your appropriate language on the Comprehensive TeX Archive Network.

Good Luck & Good Hunting.

Making A Service Launch

I hinted previously that I would launch this and that there were ironic reasons for doing so. It is best that I explain myself. Explanations generally make things clearer.

There was a push for Erie Looking Productions to return to producing at least general programming. Now that I am no longer a federal civil servant the restrictions that held me back for six years from doing so are off. The problem is that the current studio space suffered physical damage. The audio equipment and the recording computer are fine and secured but the physical space is not usable. We don't have a fallback space at this time nor do we have the economic means to procure one. Repairs to the physical space were supposed to be done this month but I have not heard much about the status of that lately.

I am also dealing with some long-term recovery from some surgery that was done. While I can talk to people it can sound slightly garbled at times. The last check-in at the doctor's office didn't show me breaking any speed records to be able to move ahead in matters so I am stuck with "slow and steady" for the time being. That is going to possibly not be fixed properly until some point in April.

While I know the folks behind the Ubuntu Podcast are planning to return to air shortly I will instead be taking a different path. The current hotness appears to be launching your own newsletter such as this technology one. Since podcasting is not feasible at the moment the reformatting of content to a strictly textual form seem like the simplest way forward for now.

I could operate an announce-only mailman list on a minimal Ubuntu 19.10 droplet on Digital Ocean. However, my current economic circumstances have instead pushed me over to trying to utilize instead. To quote the 13th & 21st US Secretary of Defense, Donald Rumsfeld, in an apt manner: "As you know, you go to war with the army you have, not the army you might want or wish to have at a later time."

The newsletter is entitled "The Interim Edgewood Stratagem". Release frequency should be once weekly but I haven't settled a firm day yet but it would likely be out on a Wednesday, Thursday, or Friday each week. We'll see how it develops. I am pretty sure we are not initially going to dive into unknown unknowns if we can help it.

Twice a month there is the chance that the text of my sermon presented on Sunday morning at the nursing home may be presented that week. Initially the first release would be in fact the text of my sermon from Sunday. That is planned to go out later in the day on February 12th.

The first regular essay would go out during the week of February 16th. In that essay I want to get to would be to talk about a bit of an unresolved mystery case involving a Pacific island nation suffering an Internet blackout. Style-wise this wouldn't be Darknet Diaries but rather something a bit different. After the Pacific jaunt would hopefully be an essay on the changing business regulation climate in the US that may not help folks in the open source world who "hang their own shingle" to work as independent contractors. Once through that we would see where stories go. I do know I do not want to talk about the presidential primary campaigns if at all possible as nothing productive comes out of worrying about them while other craziness is in play.

You can sign up at the subscribe page for free. Support is welcomed though not required through avenues such as Liberapay. If you just want to drop in a quarter via PayPal or maybe just two cents that is doable as well. The shopping wishlist for replacement gear also still exists as I watch equipment fail and otherwise decay.

This is an adventure that I am nervous about starting. Once upon a time I was a working journalist who was routinely published in print, no less. The media landscape isn't the same these days but this will likely feel like getting back on a bicycle to ride again after a long time away.

To quote a commercial that aired quite a bit a few years ago: "Let me tell you a story…"

Early February Miscellany

In no particular order:

  • After fussing with it enough I was able to move the website for Erie Looking Productions over to a different provider. Eventually there will be an SSL certificate once that actually generates within the next day or so. The transition had a few too many moving parts to it which resulted in a bit of breakage. Fortunately the website wasn't down too long.

  • I got word back that the almost-novella story I submitted for a contest didn't make it to the list for judges to consider. It is a pretty big contest. The question now is what to do with the story. It is long enough that if I utilize the novel class in LuaLaTex with appropriate font choices and set my paper size wisely I could possibly make a print offering somewhere like Lulu and just release it as an independent pocket book as well as make an ebook offering on Leanpub. Since the story was originally written step-by-step in a gitit wiki I also ended up using the markdown package found on the Comprehensive TeX Archive Network to easily shift into submission format using the science fiction manuscripts class the raw text with some bash scripting and coreutils usage. Yes, it is happened to be a dirty hack that I'm not ready to stick on Launchpad anywhere but it worked nicely. No, pandoc was not used in this scenario.

  • So far none of the packages I have installed on my Focal Fossa machine have significantly broken on me. This is good. I have been using the machine for day to day use.

  • I've disappeared from IRC again as the droplet on Digital Ocean that had my ZNC bouncer had to be turned off. I'll figure something out eventually and make a return when resources permit.

  • There may be a need for me to start a newsletter on tinyletter to try get familiar with the platform and otherwise be able to evaluate it. I cannot actually engage in podcasting right now for some ironic reasons. Considering that I cannot being on a microphone and outside being a writer or post-production editor it seems maintaining a newsletter would be an interesting side trip for now. We'll see if I have to go ahead and launch that project. Watch this space for details…

End of January Miscellany

In short:

  • ViacomCBS has an ad-supported streaming property known as Pluto TV alongside the subscription-based CBS All Access. Normally the two do not overlap in content. Currently there is an overlap as the first episode of Star Trek: Picard is playing on a loop on the Pluto TV sci-fi channel. This plays fine in Firefox without any DRM worries or need of any extensions to be loaded. As Ubuntu users look at video streaming services potentially not playing nice due to tech incompatibilities this content platform seems low-friction for getting started.

  • I forgot the birthday of Stuart Langridge yesterday.

  • Good luck to the United Kingdom with Brexit Day.

  • There was a presentation on making films with free software at 2020 that I need to watch yet and that many of us should review. With things like 8 Bit Versus out there already I frankly want to see an Ubuntu-related vodcasts aggregator site some day.

  • Ever hear the expression “good enough for government work” in the wild? Well, a font now exists in responses to that American colloquialism.

  • Eventually I will need to look at what snaps exist alongside Ubuntu Core to do something like a small scale municipal mesh as what we’ve got in terms of broadband now is not really cutting the mustard. Finding a peering partner would be hard, though.

  • For those that don’t think getting releases put together is hard enough, the PureDarwin project looks like a great source of ideas and inspiration.

A Disappearance

Although it had been limping ever onward for some time, Identica appears to have disappeared again. The pages for the underlying software itself are hosted on GitHub Pages so those haven't fallen over. There hasn't been any new project news since October 2019. There's no other status search available.

I think Coyote Works is now the sole redoubt for me in terms of online presence that I maintain majority control over. I am no longer visible in the so-called Fediverse and with Identica having disappeared again this is it. Although I may have presences in some silos that have cutesy names applied by free software activists those do not need to be linked here. Business inquiries should still be directed to the Erie Looking Productions home page.

How odd.

Approaching Month's End

In no particular order:

  • Stuart Langridge recently wrote a blog post about wanting to write more. I understand the feeling quite well. Granted, I have been looking at the 2020 edition of The Writer's Market to see what outlets are still out there accepting pieces from freelancers. The first time I ever had a freelance piece published was way back in 1998 as I wrote newspaper stories printed in newsprint. I still do that off and on. Currently I have a fiction piece that is just under the SFWA word count definition for being a "novelette" so it is instead an overgrown short story. There is more writing to be done especially as that short story is launching a conceptual universe for me to work in.

  • To the extent that they can be, significant repairs to the television aerial mast are completed. The mast-mounted preamplifier appears to be damaged. I have that bypassed for now but that resulted in reduced signal reception. Eventually I will end up securing a new one. A new preamplifier is on the purchasing list for replacement equipment needs.

  • Paperwork as to my future continues to be processed down in Slippery Rock in the Iron Mountain range. My family thinks I am kidding when I say that the agency handling everything is working in an abandoned mine next to Iron Mountain Corporation. Apparently people have overlooked the relevant Washington Post article about the place. The article talks about retirement claims but other claims are also handled in that cave too.

  • I need to go to the gym more often.

  • Life does not feel particularly secure right now.

  • Access to "normal" television is restricted right now. We only have access to free streaming as well as what we can pull in via the antenna and we cannot get the full set of Over The Air stations out of Erie, Pennsylvania. Whenever money becomes available some time in the future I may purchase a season pass on iTunes to be able to catch up on the current season of Doctor Who though catching up on American Ninja War: USA versus The World may be trickier. Paying for subscription streaming services is outside any budget sources right now.

  • The easiest way to reach me at the moment is either via Telegram or via Skype.

New NBC Streaming Service Details Announced

At this point news about NBC's "Peacock" streaming offering has shown up in multiple places. Frankly I am underwhelmed due to the paucity of actual details that could be potentially useful to me. It seems like getting a proper aerial functioning to properly receive WICU would get me more useful access to NBC programming when paired with suitable personal video recording rigging.

Have You Checked Your Patches And Updates Today?

The Cyber Infrastructure Security Agency at the United States Department of Homeland Security has been filling my inbox with updates in the past 36 hours. From an alert concerning possible cyber response to a United States military strike in Baghdad to a press release about a new analytical report concerning geopolitical tensions (which is actually a 2 page PDF file) they certainly have been issuing reports. It may be prudent in these tense geopolitical times to ensure your package updates are in fact up to date, that you're not running unnecessary services on public-facing servers, and that your firewall definitions meet current needs.

You don't want to wind up with an intrusion like the United States Government Printing Office did relative to the website of the Federal Depository Library Program.

On Events In Texas

I am going to primarily refer to the article written by Bobby Ross at the Christian Chronicle. During communion Sunday there was an active shooter event that resulted in a fatal conclusion for the shooter at West Freeway Church of Christ outside Fort Worth, Texas. Details are still sketchy as I write.

My father presided over the table Sunday morning at West Avenue Church of Christ in Ashtabula. Service was fairly uneventful. When there is a fifth Sunday to a month we usually have a "Praise & Worship" service. Songs were sung, I led opening prayer, Dad presided over communion, the located preacher/song leader handled closing prayer. I remember asking in opening prayer for strength in the upcoming new year as it is expected to be an eventful one.

Now, FEMA's Emergency Management Institute has an independent study program with a distance learning course covering mass casualty incidents at "houses of worship" and related facilities. I've run through that and several other courses. They are equal parts useful and disturbing.

Currently we don't have emergency plans. It isn't for a lack of trying on my part. Our congregation is just small enough that the feeling is that we don't need one, I guess. I can describe an unorganized measure that does help prevent bad things from happening.

Do you greet your visitors at your church? I can't over-emphasize how important that is. We have a nice guy who is a veteran who hands bulletins to people as they come in and shakes hands. The preacher and the elders also sit in the foyer between the end of morning bible class and the start of morning services. Church isn't something you do alone and helping improve fellowship can help prevent alienation. You also have to consider that if somebody wanted to cause trouble they don't want to mess with the smiling, lovable veteran handing out bulletins at the door.

Security-minded folks can look at it as a security measure. I look at it instead as a way to help build up the church body. A congregation is not supposed to be a group of lone wolves. I do suggest reading 1 Corinthians 12:12-26 for good measure.

Beyond that, church fellowship helps greatly. The average size of a congregation within a non-instrumental Church of Christ setting is one where I see multiple figures. I doubt Wikipedia's and the others out there are over a decade old. Regardless of size you still need to have fellowship among the members of the body. You need to be able to connect.

I've worshipped with tiny congregations and huge congregations. I've worshipped in urban areas and worshipped in a rented space in the Territory of American Samoa. I preach twice per month to bring the word to people at a local nursing home. Incidents of violence at churches are not earth-shattering threats. If you thoroughly read the book of Acts, the apostle Paul thoroughly gets the tar beat out of him in his missionary journeys. We live in a fallen and broken world and for a faith tradition of primitivists we have to think very hard about how things are reverting to the way they operated in more biblical times. See, for example the incident in Ephesus.

For now, I move forward. I'm not sure I'll say anything at West Avenue. I am our trained person on homeland security sorts of issues. For the most part we are on our own for quite a few minutes whether it comes to needing a response from police or emergency services. Building up our resilience is needed for the littler things.

Stepping boldly forward into the future is the best thing we can do, I think.
