Just to save anyone from searching for some secret mode on their calculators, I misspoke. I mention using my TI calculator in “Degree Mode”. I meant to say “Normal Mode”. It just happens to say DEG on the screen in tiny letters. What can I say, I’m easily distra
Oh look at that!

David Whitman encourages you to choose Aperture as the most important setting in setting up your camera.
Understanding Exposure, 3rd Edition by Bryan Peterson - a good book that is great for learning photography. Duck Duck Go can connect you with a place to buy this book.

Have some fun. Take some photos and do a HPR episode.
Instantiate a git repo:
$ mkdir alice
$ cd !$
$ git init
Add a remote:
$ git remote add origin URI_OF_REMOTE
Change a remote:
$ git remote set-url origin NEW_URI
A remote can be a server, it can be a local directory, an NFS share, pretty much whatever you want.
It is a Git convention that the primary remote is called origin. You don't have to call it that, but it's pretty common.

Diffie-Hellman Key Exchange is based on work initially done by Ralph Merkle, and remains one of the key developments in secure communication over the Internet. In this episode I try to explain just how this works, with an example of a calculated key exchange.

In this episode, the HPR_AudioBookClub discusses Matcher Rules by Mary Holland https://scribl.com/books/PDB66/matcher-rules
As usual, the HPR_AudioBookClub took some time to review the beverages that each of us were drinking during the episode
We discuss the upsides and downsides of affinity groups. Pokey wonders why terminology for simple things are changed in sci-fi stories. How exactly do population and economics work together?
Blood Witness by David Hitt - https://scribl.com/books/PA513/blood-witness
We are currently working through a backlog of pre-recorded episodes. Once this is completed we will restart the Audiobook Club again. If you want to be notified when this happens please let us know via the HPR Mailing List 'hpr at hackerpublicradio dot org'.
Nothing this time, well except for the typical Star Wars reference...and Star Trek, and comics.
Thank you very much for listening to this episode of the HPR_AudioBookClub. We had a great time recording this show, and we hope you enjoyed it as well. We also hope you'll consider joining us next time. Please leave a few words in the episode's comment section. As always; remember to visit the HPR contribution page HPR could really use your help right now. http://hackerpublicradio.org/contribute.php
Sincerely,
The HPR_AudioBookClub
P.S. Some people really like finding mistakes. For their enjoyment, we always include a few.
This episode was processed using Audacity http://audacity.sourceforge.net. We've been making small adjustments to our audio mix each month in order to get the best possible sound. It has been especially challenging getting all of our voices relatively level, because everyone has their own unique setup. Mumble is great for bringing us all together, and for recording, but it's not good at making everyone's voice the same volume. We're pretty happy with the way this month's show turned out, so we'd like to share our editing process and settings with you and our future selves (who, of course, will have forgotten all this by then).
Mumble uses a sample rate of 48kHz, but HPR requires a sample rate of 44.1kHz so the first step in our audio process is to resample the file at 44.1kHz. Resampling can take a long time if you don't have a powerful computer, and sometimes even if you do. If you record late at night, like we do, you may want to start the task before you go to bed, and save it first thing in the morning, so that the file is ready to go the next time you are.
Next we use the "Compressor" effect with the following settings:
Threshold: -30db
Noise Floor: -50db
Ratio: 3:1
Attack Time: 0.2sec
Decay Time: 1.0 sec
Make-up Gain for 0db after compressing" and "compress based on peaks" were both left un-checked.
After compressing the audio we cut any pre-show and post-show chatter from the file and save them in a separate file for possible use as outtakes after the closing music.
At this point we listen back to the whole file and we work on the shownotes. This is when we can cut out anything that needs to be cut, and we can also make sure that we put any links in the shownotes that were talked about during the recording of the show. We finish the shownotes before exporting the .aup file to .FLAC so that we can paste a copy of the shownotes into the audio file's metadata. We use the "Truncate Silence" effect with its default settings to minimize the silence between people speaking. When used with its default (or at least reasonable) settings, Truncate Silence is extremely effective and satisfying. It makes everyone sound smarter, it makes the file shorter without destroying actual content, and it makes conversations sound as easy and fluid during playback as it was while it was recorded. It can be even more effective if you can train yourself to remain silent instead of saying "uuuuummmm." Just remember to ONLY pass the file through Truncate Silence ONCE. If you pass it through a second time, or if you set it too agressively your audio may sound sped up and choppy.
At this point we add new, empty audio tracks into which we paste the intro, outro and possibly outtakes, and we rename each track accordingly.
We adjust the Gain so that the VU meter in Audacity hovers around -12db while people are speaking, and we try to keep the peaks under -6db, and we adjust the Gain on each of the new tracks so that all volumes are similar, and more importantly comfortable. Once this is done we can "Mix and Render" all of our tracks into a single track for export to the .FLAC file which is uploaded to the HPR server.
Remember to save often when using Audacity. We like to save after each of these steps. Audacity has a reputation for being "crashy" but if you remember save after every major transform, you will wonder how it even got that reputation.

Listen to me walk through five shopping malls and one bicycle tunnel, as I rant about how flow-based programming microservices and functional package management will save the future of programming and software reuse, and usher in a new era of software quality and productivity!
If it sounds like I'm a bit down about working alone on racket2nix, you're interpreting me wrong! I didn't expect any feedback at all from the small to non-existent racket/nix intersection, but it turns out the intersection is larger than I thought, and I'm grateful for any words of encouragement, and feedback in any form on what the community needs.
