My current music setup is a Raspberry Pi 3 with a HifiBerry DAC+ audio card as my music player. It works perfectly, except for one annoying thing. The new HifiBerry DAC+ makes an audible click or poping sound when changing the sampling rate. I have a lot of recordings in higher resolution than CD-quality of 16-bit 44kHz, so it’s jarring when it happens. I like to play my music loud which exacerbates the problem. But there’s an easy solution, and at the same time, you can get better sound quality overall. Here’s how to fix the problem.
I’ve written an article on how to remove the purgeable portion on a hard disk on Mac OS, but in High Sierra, Apple has changed the file system from HFS+ to APFS. Because of that, my old guide doesn’t work. So here is how to remove the Purgeable part of the disk in Mac OS High Sierra.
Finding System Files in Finder
Don’t you hate it when you need to find a .plist settings file or any other file that is in one of the Mac OS system files folders? I do. So here is a little tip on how to do global system files search directly in the Finder.
Can’t Remove Purgeable Disk Space
When trying to install Bootcamp on my MacBook Pro, I had to delete a lot of files to get enough space to be able to accommodate for a Bootcamp partition on the drive. But even after removing around 60 GB of storage, Mac OS Sierra could still not make a large enough partition for Windows. When checking with Disk Utility it showed that indeed I had enough space, but there was a part called Purgeable that was impossible to move. No tools from Apple are available to handle this, but here’s how I fixed it.
Make your Single Board Computer shine with DietPi
My wild guess is that most people get a small Linux computer, like the Raspberry Pi, BeagleBone, Banana Pi or Orange Pi for a specific task. Unfortunately, most distributions are chock-full of software, with everything installed per default. But if you want to set up a lean single board computer for a specific task, you’re out of luck. Thankfully there is a Linux distribution, DietPi, that aims to fix that problem.
