I just posted a video about purchasing an EOS R. While originally intending to jump to the R5, I just couldn’t justify purchasing one at this point. But then I realized the EOS R is actually a really great choice right now, and works well as a bridge camera for my switch to the RF camera system. I talk about some of my thought process here…
The memory bandwidth on the new Macs is impressive. Benchmarks peg it at around 60GB/sec–about 3x faster than a 16” MBP. Since the M1 CPU only has 16GB of RAM, it can replace the entire contents of RAM 4 times every second. Think about that…
Some say we’re moving into a phase where we don’t need as much RAM, simply because as SSDs get faster there is less of a bottleneck for swap. Indeed, SSDs have made significant strides, especially with the newest Samsung 980 NVMe drives pushing 5-7GB/sec. This is closer to the memory bandwidth than we’ve ever been with consumer-grade hardware, and you’re only running about a third of the speed of main memory in a 16” MBP. However, with the huge jump in performance on the M1, the SSD is back to being an order of magnitude slower than main memory.
So we’re left with the question: will SSD performance increase faster than memory bandwidth? And at what point does the SSD to RAM speed ratio become irrelevant?
Theoretically, SSD swap is “fast enough” if it can load data from a backgrounded app into main memory before the user notices a delay when clicking an icon in their Dock. Once this threshold is reached, there’s not much of a distinction between an app being open or not.
I do believe that a limited amount of RAM is becoming less of an issue as time goes on. As I’m writing this, I’m 5GB into swap on my 16” MacBook Pro with 32GB of memory. In years past, a Mac 5GB into swap would have felt like it was crawling. However, today I haven’t noticed a single hiccup, and honestly wouldn’t even be aware of the swap usage if XRG wasn’t sitting on my desktop telling me so.
Would I buy a Mac with 16GB of RAM to use as a primary development machine today? No, probably not. While I don’t typically notice a speed decrease due to swap usage, I don’t think that storage threshold has been reached quite yet. However, I’m looking forward to Apple’s answer to the higher-end market and am confident they have M-series chips with more RAM in the pipeline.

Looking forward to reading my Twitter feed without having my blood pressure rise again.
It’s hard to believe it’s been more than a year since we visited Papua New Guinea. I’ve been thinking about creating this short film ever since. A couple of months ago, after deciding I had procrastinated long enough, I got started on the project. Here’s the final result: my story of our visit to Normanby Island…a day I’ll never forget.

Impressed with the responsiveness to Apple radars lately.
I reported two bugs with SwiftUI on Big Sur in the last few months, and both issues have already been fixed.
Watched the season finale of Ted Lasso tonight. Best show I’ve seen in years. Can’t wait for season 2.
I pulled the trigger on a Pro Display XDR. It’s amazing for photo and video editing, of course. But what made it worth every penny is being able to view 3 full size code panels in Xcode while still showing both toolbars.

Blows my mind that you can buy a 16TB disk for just over $300 these days. The internal mechanism is a 7200 RPM enterprise class Exos X16 to boot.
Finished importing 584GB of video for a project. Had three cameras going, plus separate audio from an external mic attached to my iPhone.
Can’t say I’ve ever seen two NSAutoresizingMaskLayoutConstraints colliding with each other. This should be an interesting bug to work through.
Taking some time to enjoy a peaceful summer day in #PureMichigan.
I went out a couple of nights to view the Neowise comet. Here’s one of the better shots I came home with.
Used a 5D Mark IV and a 70-200 f2.8L II. 5 second exposure at f2.8, 70mm, ISO 10000.
Just finished renaming 1.5 million weather observation data files from epoch to YYYYmmddHHMMSS date format.
Took a couple of days intermittently and some bash and Perl code to get the job done.
The DTK arrived this morning… So this is what it’d be like if an iPad Pro ran macOS.
First step: getting XRG going.
Now that WWDC is over (kudos to everyone at Apple!), we can now return to our regularly scheduled political posts.
I just posted a video discussing my thoughts on this week’s WWDC announcements including macOS 11, Catalyst, SwiftUI, and Apple Silicon.
