Yesterday during computer class, we started learning how to use the music engraving program .

We began by going through the lilypond tutorials at:

At first, we were writing the score in emacs, but then we installed frescobaldi to use as a minimal GUI. Really nice piece of software!

My son is really into playing along with files on the , so he wanted to generate midi output from lilypond.

One of the issues we encountered was connecting timidity to the midi output port. We ended up using the method here to start timidity as an ALSA sequencer client (without blocking all other audio playback system-wide):

After that, we were able to play the music via midi output using the following lilypond example:

depression, self-awareness, expecting too much from yourself 

@KAOS You might try mindfulness meditation. Every morning my kids and I read from a meditation book for ~10 minutes and then do a 20 minute meditation. Self-compassion is one benefit that I've experienced. Right now we're reading "The Buddha's Brain". I recommend it.

There was a point in time ~10 years ago where I used the Gnus email client (emacs). Well, I lost those emails somewhere in my data archive. I managed to find them by grepping my old email address.

At first, it was taking forever, but I discovered the -I option to grep: "Process a binary file as if it did not contain matching data".

Once located, I needed to convert them from NNML to mbox format. I used the script here:

Except instead of calling mailbox.Maildir(), I called mailbox.MH().

Finally, all I had to do was import the mbox file with the ImportExportTools NG extension in Thunderbird. My email archive is complete!

@selea I use Blender for all of my wood/construction projects. There was serious learning curve, but it was worth it. Here is the design for a dog crate/kitchen island I recently did.

Wow, devs have been discussing an "Encryption when possible" option for 20 years.

I think an option like this makes a lot of sense!

@freeschool Beefier, compared to my current Raspberry Pi 4 :)

You probably take more photos than I do, but for me it's easy enough to just hit Delete (no confirmation). I use my desktop for this.

@freeschool What I do now is sort the photos once a month into galleries like this:

YYYY/YYYY-MM [name]/

That makes it really easy to get an quick overview of a large number of photos.

When I get a beefier server for my LAN, I plan on trying out some photo management software (like Piwigo), but I'll never rely solely on image metadata to organize my photos again.

Continuing with my recent kick, I've been deleting the last 20+ years of digital photos from Google Photos. This was my final repository of unencrypted private data in the cloud.

It turned out to be quite a project, since Google doesn't provide a straightforward way to bulk delete photos. I ended up using this script:

It's been running for days. I think it will finish today.

Today in computer class, we set up OpenPGP encryption in Thunderbird.

We used the following guide:

There was just one missing configuration setting in that tutorial. In the account settings under end-to-end encryption, the default key needed to be changed from "None" to the one we just generated.

We also set "Require encryption by default", but what I really wanted was a "Use encryption when possible" config setting.

For the dedicated Gmail webmail users in our lives, we will see if fits the bill.

@softinio I use the Contacts, Notes, Bookmarks, and Music add-ons the most.

@aw Looks really nice. I'm curious, how would spam be handled?

We watched the Horizon episode “Living with Autism” last night.

I have always been aware that my son and I have certain autistic traits, but I wasn’t sure if we would be diagnosed as autistic. After watching the Horizon episode, I don’t think we would.

As they described it, the number of autistic traits per person across the population follows a normal distribution. The average person actually has quite a few autistic traits. It’s only when the number of autistic traits in that person is >50 (looked like 2 std deviations from the mean) that they would be clinically diagnosed as “on the spectrum” (I’m not sure if they understand what a spectrum is).

I’ve attached an image from this study that shows a figure similar to what they showed in the episode.

So, yes, while many people would consider me socially inept, I do get by okay in life and don’t think I should pursue a diagnosis. On the other hand, my attention to detail has been one of by greatest strengths.

I found the autistic couple in the episode very interesting. They obviously have a great relationship, but I wonder if a better strategy would be to find a not-so-autistic mate who can help to round out your abilities a bit (if you can manage to get along).

We’ve been going through Linux Survival during our computer class. These are really good hands-on exercises for the n00b.

A couple of days ago I injured one of my costochrondal joints doing a clean (first rep of first set of the day). Apparently I didn't warm up enough and had poor form. I was also trying out a new kettlebell (10# heavier).

Shortly after our workout and for the rest of the day, I could hardly breathe without pain. After some reading about it, I was convinced it was going to take several months or up to a year for me to heal.

Today, I did my workout as scheduled. I feel mostly fine, amazed at my body's ability to heal itself.

I learned some important lessons about form, warming up, going heavy, and getting old.

Light day:
- 4x50 kettlebell swings
- 3x16 kettlebell deadlifts
- 3x20 military press
- 2x(4,5,6) pull ups
- 2x(8,10,12) push ups

Also, the difference in weight loss could be entirely attributable to a difference in physical activity.

Also, at the end of the program, the insulin results and the doctor’s reaction to it made absolutely no sense to me. I went looking for other reviews to this episode and found this one. It provides another interpretation of the results.

A close family member was recently diagnosed with type II diabetes, so I thought it would be appropriate to watch the Horizon episode “Sugar v Fat” last night.

I was surprised at the results of their experiment. I expected the twin on the high-sugar diet to have gained weight. Both twins actually lost weight. Although the twin on the high fat diet lost more. They were apparently too low in their calculation of daily caloric needs.

It’s one thing to see these results in a one month-long experiment, but in a real-life diet the effect of ghrelin (hormone that controls hunger) would be a huge factor. The twin on the high-sugar diet ate less protein and would be perpetually hungry. It wasn’t clear how much willpower it took for the twin on the high sugar diet to eat within to the experimental parameters.

Did the twin on the high sugar diet really go a month with virtually no protein? That doesn’t seem safe.

It wasn’t clear if the twins were actually eating the same amount of calories. The twin on the high fat diet lost more, so I assume he ate fewer calories.

No mention of individual differences in the larger study results that they cited, only averages. I suspect there were individual differences, due to genetic differences. For example, the CLTCL1 gene.

The twin on the high-fat diet lost more muscle because he lost more weight. Training with weights would have reduced muscle loss.

This aired in early 2014. We’ve come a long way since then.
