One way to hide the contents of a file, e.g. one containing environment variables containing secrets, is to use gpg symmetric encryption, which meb7 ans encrypt and decrypt use the same secret. It is convenient, and you can supply the secret when you need it. 🤖
The encrypt command will create a file
vars.txt.gpg and if you list its contents you will see they are encrypted.

If you are using the aws cli tool, you can set the shell env var «AWS_PROFILE» to match your setup profile names linking to specific IAM credentials. 🍺 Here it is in a zsh function.
This function sets some local vars, sets AWS_PROFILE via
export then confirms it is set, then builds and deploys the site via
hugo deploy. The site has a config file with the “coolsitejp” target, and under that is specified which AWS S3 bucket to deploy to. Use
export instead of a simple assignation like I am doing with
_hugobin etc, because you want to have the variable ready for use when the script invokes
hugo to build and deploy the site. The last line unsets AWS_PROFILE for good measure if it was not set already, or resets it to whatever it was set to initially.

If you have AirPods Pro headphones there is a firmware update (from 2D15 to 2D27) with no details on what it does. How to update? 🤔 Nobody can say.
Apparently, if you listen to music for a minute or so, then put the headphones in their charger and connect to power, they update in a few minutes. It may be voodoo majick but it worked for me.
Confirm the before and the after:
- Connect to your iOS device.
- Open Settings, then go to General -> About.
- Find your AirPods and tap the name.
- Find the firmware version. (Take a screenshot which on my XS is: press big right button and volume up button simultaneously)
I connected a new ELECOM WRC-X3000GS broadband router that supports «Wi-fi 6», or IEEE 802.11ax via an Intel WAV600 chipset, with high hopes for 9.6 Gbps goodness. It connected to my Docomo hikari line without any settings (convenient!) but kept dropping the connection. 👺 A call to Elecom support solved it straight away.
The support professional suspected she knew what it was, and had me check the PPP LED on the unit. It was off. She asked if I had entered the ISP credentials and I said no, it just connected. She told me that that kind of connection is kind of a test mode and recommended I check my ISP information again for login information. She directed me where to enter it, and sure enough, once I did that, the unit is stable and fast.
Still, I find it really odd that the installer would not mention this important fact. The Amazon reviews section is full of people grousing about how bad the router is and that it drops its connection, so I bet others are getting hit with this same thing and just giving up.RC Logr 20200625 084815 - I connected a new ELECOM …

I use some integrated AWS services to host some sites, including S3 for basic hosting, Cloudfront for CDN, Certificate Manager for SSL and Route 53 for DNS. Who doesn’t like automation? 🤖 A couple of notes:
- Re ACM SSL certs, what worked well for me is to add the wildcard (*.cogley.info) as the basic cert name, and the apex as an additional name (cogley.info). Also, DNS validation is convenient because you don’t have to do anything but fail to delete the CNAME you need. If you use Route 53 it’s even better since there’s a big button that will create the CNAME for you. Once the CNAME is there, ACM will just happily renew for you. Ahhh, bask in the automation.
- You can have multiple copies of a cert. It’s either in use or it’s not, so just get it right, then delete the ones you don’t need. Cloudfront will re-deploy within a few minutes anyway, so it’s really no big deal to make a mistake.
- In your Cloudfront distribution edit screen, once your certificate is validated, you can just type
*.mydomain...and it will show you the choices that match. There’s a UUID identifier you can get from the cert itself, which appears in the dropdown, just in case you have multiple certs that match.
- Again in your Cloudfront distribution, make sure to choose TLS 1.2 (TLSv1.2_2018), which is the spec from 2008. At this point, so much time has passed that I think it’s safe to not pander to people with browsers from earlier than that.

I updated MacOS to 10.15.5 yesterday via the combo updater (i.e. the non-delta updater), and my Mac was immediately crash-y, with several freezes in a row. And here I was expecting stability! 🥴
At any rate, I dug out the notes and did an NVRAM / PRAM and SMC reset. TL;DR: that fixed it. (Though admittedly it might just be voodoo-magick thinking)
NVRAM stores settings like your sound volume, display resolution or timezone. Reset it like this:
- Shut down your Mac
- Turn it on, while holding ⌥ + ⌘ + P + R.
- On newer Macs (with the T2 chip) wait until the logo appears and disappears twice, then release. On older macs, wait until the second startup sound and then release.
- Check system preferences for changed settings related to sound volume, startup disk, display resolution or time zone.
SMC or System Management Controller controls the power, fans and thermal management, battery, USB, indicators, lid opening and closing and so on. Reset it per Apple Instructions and here’s an subset example for a newish Mac notebook with a T2 chip:
- Shut down your Mac
- Press Left⌃ + Left⌥ + Right⇧, and the Mac turns on.
- Hold the 3 keys for 7 sec, then hold down the power button as well. Your Mac will turn off.
- Hold the 4 keys for another 7 sec, then release.
- Wait 10 sec, then power on.
These took a few minutes but, I have not had a crash since I did it.RC Logr 20200605 083345 - I updated MacOS to 10.15.5 …

A friend reminded me of a great GUI utility called «balenaEtcher», which lets you flash OS images to SD cards and USB thumb drives. Etcher is way easier than using
dd, that is for sure. It just works. 🤓
Here’s what you need to do, if you want to do it manually on a Mac:
- Insert the SD card.
diskutil listin terminal and find the identifier.
- Unmount the disk using
diskutil unmountDisk /dev/diskNwhere N is the correct identifier. Don’t screw it up.
- Copy the image using
sudo dd bs=1m if=/path/to/OS_image.img of=/dev/rdiskN; syncwhere N is the correct identifier, noting that
rdiskstands for raw disk, which speeds things up. If you screw it up you can munge your main drive…
- Eject using
sudo diskutil eject /dev/rdiskN.
