For my Raspberry Pi Time-Lapse App, I find myself having to either copy hundreds (or thousands!) of 3+ MB image files, or a 1-2 GB video file from a Raspberry Pi Zero W to my Mac.

Copying over the WiFi network works, but it's extremely slow (usually topping out around 5 Mbps... which means it could take a couple hours to copy). So I decided to finally try to mount the Raspberry Pi's drive directly on my MacBook Pro (running macOS Sierra 10.12). This is normally a bit tricky, because the Raspberry Pi uses the Linux ext4 filesystem—which is not compatible with either macOS or Windows!

If you've had an AirPort Extreme for a while, and recently (within the past year or two) had it go missing from your network (when you open AirPort Utility you get 'Device Not Found'), there's a good chance you ran into the same issue I did. Basically, everything was running great, then one day around August 2016, my Extreme disappeared from the network—even though it was routing Internet traffic for all the devices in my house just as good as ever!

The fix?

1. Open AirPort utility (it will likely show "Device Not Found").
2. Unplug your AirPort Extreme, and wait 10 seconds.
3. Plug it back in, and connect to the WiFi network as soon as possible, then immediately go to the AirPort Utility.
4. The AirPort should appear and be manageable (by clicking on it) for a brief period—quickly click on it, click Edit, then clear out any Apple IDs in the 'Back to My Mac' section.

A few months ago, I switched to Safari after having used Google Chrome exclusively for the past four years (before that it was a mix of Safari and FireFox). Safari is lean and fast, but the one thing that really bothered me was the fact that I would often try searching for something by entering keywords in the location/address bar, then hit enter, and nothing would happen.

I quickly realized that if I did this and nothing happened, I could jump back into the location bar (⌘-L), press the left arrow key to get my cursor in the beginning of the string, then hit space and enter to perform the search.

Until today, I've begrudgingly used that workaround. But then I was checking Safari's preferences to see if I might be missing something obvious, when I decided to uncheck some options and see if it made a difference. And it did!

tl;dr: There are many ways to capture time-lapse videos. But this one is cheap, completely wireless, and mine. If you want to skip the post and go straight for the glory, grab a copy of my Time-lapse app for the Raspberry Pi.

Time-lapses transform subtle, slow processes into something beautiful, and often make us think about things in new ways. For example, have you ever thought about just how heavy a wet snow is? The trees in your yard might know a thing or two about that! Check out a time-lapse I recorded this morning some mighty oak tree branches, as they relaxed upward as if in relief from the wet snow falling off:

tl;dr: My left AirPod had some hardware issue. I got a new one. Now the AirPods work great.

The morning Apple's AirPods went up for sale, I was boarding a plane, and had just gotten to my seat on the plane. I knew they'd be in short supply (though I didn't know just how short—my local Apple Store only gets a small batch every week, and they're sold out in hours!), so I quickly ordered a pair, then set my iPhone in airplane mode for takeoff.

These things are awesome... though a little pricey.

A few months ago, I decided to get more serious about my recording setup in my home office. I do a lot more screencasts both for my YouTube channel and for other purposes than I used to, and I can't stand poor audio quality. Therefore I finally decided to get some sound absorption panels for my office, rearrange furniture a little for better isolation, and—most importantly—buy a proper USB audio interface and microphone.

So, after purchasing and connecting a U-Phoria UMC202HD and an Electro-Voice RE320 microphone, I was quite pleased with the sound quality!

I recently migrated around ~50,000 photos and videos from Aperture to Photos (see my blog post on the process), and have also in a short amount of time upgraded my personal and work Mac laptops (both from older MacBook Airs to newer MacBook Pros).

On both of my new laptops—which were at least 3x faster than my older Airs—I noticed that Photos started completely fresh in its photo analysis for the 'People' album that shows everyone's faces. And after three weeks of seeing one of my CPUs stick around 100% all day every day (while plugged in), I started getting sick of this.

I would leave the Mac on all night, and check in the morning, and only 20-30 new faces would be recognized.

Some days it seemed it would take forever...

tl;dr: After two weeks of use, I returned my 2016 13" MacBook Pro with Touch Bar and bought one with Function Keys instead. Read on for detailed Battery stress tests, performance tests, and an exploration of how Apple's botched this year's Pro lineup.

I've owned almost every generation of Mac desktop and laptop computers, and have survived many transitions: 680x0 to PowerPC, Classic Mac OS to OS X, to the PowerPC to Intel switch. I've also owned almost every generation of iPhone and iPad. I even maintain a huge list of all the Macs I've owned! I could justifiably be labeled an 'Apple fanatic'.

I use a Mac as my daily driver, and have rarely made a tech-related purchase I regretted. And I've never returned a Mac, until today.

From time to time, I need to clean off the contents of a hard drive on one of my Macs—most often this is the case prior to selling the mac or giving it to someone else. Instead of just formatting the drive, installing macOS, then handing it off, I want to make sure all the contents I had stored on it are irrecoverably erased (I sometimes work on projects under NDA, and I also like having some semblance of privacy in general).

Disk Utility used to expose this functionality in the UI, which made this a very simple operation. But it seems to have gone missing in recent macOS versions. Luckily, it's still available on the command line (via Terminal.app):

diskutil secureErase freespace 0 "/Volumes/Macintosh HD"

This command would write zeroes on the entire 'Macintosh HD' drive. You can see a list of all the drives connected to your Mac with ls /Volumes. There are a few other common options available (instead of 0) if you run man diskutil and scroll down to the secureErase section. I most commonly use:

I have a 2016 MacBook Pro (without TouchBar), and for this Mac, or for a 12" MacBook, a hub/adapter with power delivery is absolutely essential for desk use, due to the limited number of USB-C/ThunderBolt 3 ports.

Eventually, I'd like to plug one ThunderBolt 3 cable into my MacBook Pro and get 4K video at 60Hz (through either USB-C, DisplayPort, or HDMI 1.2+), USB 3.0 for my existing USB 3 devices, and a power pass-through so I can get the full 61W of charge out of my Apple AC adapter.
