12:37:35 < jthan> hahaha
12:37:43 < jthan> you should just make that the subheading on the post

(If you got here from my Opensource.com article, you may be interested in the unedited version of the article as well.)

So we’ve done a lot of work on our podcast. Our previous site was an absolute mess, to be quite frank.

However, the new site is something we like and while sure, it isn’t perfect and a little bland to look at, it’s certainly much more functional.

Hopefully this should get you started. Note that I gloss over a lot of “common” knowledge (such as configuring DNS records and the like). If you don’t know how to do/understand those things, you most likely should be paying someone who does.

It also doesn’t cover how to add your podcast to iTunes syndication, nor GooglePlay syndication, etc. But there’s lots of articles out there to do that.

If you have any questions or need any clarification, feel free to contact us or add a comment.

The Basics

Hosting

You’ll obviously need hosting. We recommend a VPS as long as you know what you’re doing, because then you have root access. However, MOST of this should work fine with shared hosting. We use Linode (but aren’t sponsored by them).

We run off an Arch VPS instance, and run Nginx.

Nginx

The following is a complete Nginx config for how we run things with Textpattern:


server {
  listen [::]:80 ipv6only=off default_server;
  listen [::]:443 ssl ipv6only=off default_server;
  server_name sysadministrivia.com;

  ## SSL ##

Note that your paths may differ, you may have to modify it or create some directories, etc. You may want to refer to my devblog’s post on getting an A+ in Qualys’ SSLabs for more information on how that SSL/TLS is set up (be sure to also refer to certs).

Domain name

You’ll need a domain name. Obviously. We use (but certainly aren’t sponsored by) Namecheap. If you use Linode, they have nameservers you can use. Or you can run your own nameserver (I recommend PowerDNS). Otherwise you’ll have to set your records up at your registrar (they usually offer gratis nameservers).

SSL/TLS Certificates

You’ll also need TLS certs. We use LetsEncrypt. I have some notes on on LE over at my devblog. Don’t forget to gen your own DH params because Logjam is a thing.

Software

Textpattern

Lastly, you’ll need the web application to drive/serve your podcast- at the very LEAST your XML feeds, but it’s a good idea to have the ability to present other media/content as well. For that, we use Textpattern. (Be sure to also see Nginx!)

However, you can’t just install it and start broadcasting feeds. After doing initial setup, you should run the Podloader’s SQL import. By default it creates (overwriting any existing) a table called “myTBL”. If you wanted to instead use a table called, say, “episodes”, you’d do sed -i -e 's/myTBL/episodes/g' blank.schema.sql first.

Once you’re ready to create the table, you’d simply import the .sql dump. Something like this should do it: mysql textpattern < blank.schema.sql. Obviously replace “textpattern” with whatever your TXP DB is named.

You’ll also need to install a couple Textpattern plugins:

  • adi_menu (we use 1.4beta2; you should be able to find a copy on the TXP forums)- not strictly necessary, but it’s very helpful. Our menu is laid out like this.
  • mg_setheader (we use version 0.1)
  • pax_grep (we’re on 0.2.1)
  • smd_query (we use 0.50)
  • soo_toc (version 0.1.4)- not strictly necessary, but useful for adding table of contents to make your shownotes easier to navigate

Once those things are done, we need to customize Textpattern a bit. You’ll need to create categories for your articles- you can see how we set ours up here. Note that this integrates very tightly with adi_menu so note the naming. You’ll also need to set up some links to get that menu working as well; you can see how we did it here.

Now we need to set up some pages (Presentation > Pages). These manage generation of the specific XML feeds (which is what podcast clients use). Note that the below assume you named your table “episodes”.

feed_google:


<txp:mg_setheader value="application/rss+xml"/><txp:smd_query query="SELECT episode FROM episodes"><txp:variable name="episodecnt">{smd_allrows}</txp:variable></txp:smd_query><?xml version="1.0" encoding="UTF-8"?>

Then make sure you add your podcast when everything’s all done.

Then we need to set up some forms (Presentation > Forms). These are used to aggregate each episode into the feed’s XML.

Now, assuming everything else is all set up correctly, when you post shownotes, you’d format them as normally, and place them in the “episodes” section you created earlier, and set the category to the season, and then (this is the magic part, so make sure you do this) set the “URL-only title” under Meta to be the matching entry in your episodes table (if you’re using the blank.schema.sql dump, this column will be called “episode”- reference the queries done above).

Note that there will be some queries done every time the feed is fetched. For this reason, I recommend you set up nginx caching for your feed URLs but it isn’t necessary.

Uploading

You’ll also need a way to create and upload your media files. We use Mumble to converse with each other (we don’t record in the same room, since we live kind of far apart from each other). While Mumble has recording support built-in, we all actually run local instances of Audacity as we’ve found we get better recording with that, even for local tracks. We then export to FLAC (since it’s lossless) and upload to a central location via scp. I download the co-hosts’ tracks and do a bit of preliminary track cleanup, then re-upload. Our editor then downloads using WinSCP and does her thing, and uploads the (separately exported) edited FLAC tracks again. Then I use Podloader (a python script I wrote) to convert the final cut in FLAC over to MP3 and OGG, insert the entries in the “meta” table (see Textpattern), sign the episode files, and upload the episode media and GPG signatures.

WHEW.
