Writing

Lately I’ve been upgrading and making improvements to my website and blog. As part of that work, I was updating and refining how my RSS feed gets generated with Jekyll. And then I realized something that I had not given much thought to previously. When including the full content of blog posts in an RSS feed, if you link to other posts or pages on your site should you be using absolute URLs or are relative URLs ok?

For the past few weeks I have been debating on whether or not to distribute a new Mac app via the Mac App Store or independently. I have arrived at a crossroads in development where I need to make this decision. I am mostly code-complete for my MVP 1.0 release. The question I am facing is how I want to spend the remainder of my time to cross the finish line.

I think App Library is one of the best features added to iOS in the past few years. I’m not being sarcastic, I know some folks dislike it. However, I absolutely loathe trying to organize apps on my phone into folders, because many apps do not have a singular, definitive category.

I upgraded to Big Sur three months ago. I know I’m (fashionably?) late to this party, but here I am. This is the longest I have ever waited to upgrade macOS. It feels weird, considering WWDC is next week where we will see what is next for macOS. Big Sur still feels new to me, and announcing the next major release already feels too soon. I was avoiding Big Sur based on various reports about bugs and instability. There were not any ‘killer’ features I was eager to have, thus the main reason I upgraded was because Xcode 12.5 required it.

Previously, I wrote about Time Machine “error 45”, an obscure bug in macOS Catalina. I still have no idea what was causing backups to fail, nor what “error 45” means. However, I am happy to report that I think this issue has been fixed in Big Sur.

A few months ago, I shared my notes and resources for learning about compilers and LLVM. It turned out to be pretty popular and folks seemed to find it useful. So I decided to do it again, but this time for SwiftUI. However, unlike learning about compilers and LLVM, I am not declaring bankruptcy with learning SwiftUI. While I have still not written a single line of SwiftUI code, I know I eventually will.

Despite the fact that closures (and functions) are reference types in Swift, they cannot be compared using == or ===. But why?

One aspect of using OmniFocus involves maintaining an archive of your data (if you choose). Over time — think years of using OmniFocus as your main task management tool — your local database of projects and tasks will grow very large, because OmniFocus keeps a record of everything you have completed or dropped. You can think of it as archiving your emails instead of putting them in the trash.

Over the past few years, Apple seems increasingly willing to cooperate with authoritarian governments, uninterested in protecting its own users, and unwilling to actually standup for human rights in broad terms, as often portrayed by its marketing department or direct statements from CEO Tim Cook.

UserDefaults is one of the most misused APIs on Apple platforms. Specifically, most developers do not handle default values correctly. In fact, I have never worked on a single production codebase at a company where this was done accurately. Most libraries get it wrong, too.

After only five days, yet another mass shooting has happened in the US. This post follows Part 1 and Part 2 in this ongoing series documenting how the US is recovering from a life-threatening virus.

Lately, it feels like every few days someone is sharing a new Xcode tip on Twitter or on their blog. They range from hidden settings to features I simply never knew about. I started saving links and planned to add a new “Xcode tips” section to my TIL repo on GitHub to reference later. But as I started, I realized that the resulting markdown file would not be easily discoverable or shareable. I thought, wouldn’t it be nice if the iOS and macOS developer community had a single place to find and share Xcode tips?

As I continue to pursue Mac app development more seriously, I can build on and borrow from my many years of iOS experience. While many aspects of writing Mac apps are very similar to iOS, or at least somewhat familiar, other aspects are quite different. One of the big differences is testing, and deciding how many versions of macOS to support.

I have a few Swift scripts to automate tedious tasks for maintaining my blog. I updated one today to use pipes. It took me a minute to figure out, because it did not feel very intuitive. I’m not sure if I feel that way because the interface is actually that clunky, or if I’m just inexperienced with Swift scripting. In any case, here’s how it works.

Xcode’s UI testing framework has had its ups and downs over the years. Most recently, it has been much more robust and reliable in my experience. However, tests still tend to flake sometimes. Here are some ways that I have been able to reduce flakiness in UI tests.

I did not expect that I would have to follow-up on yesterday’s essay so soon, but I can’t say I’m surprised. In the past 24 hours, there were two mass shootings in the US. It is shocking and horrifying, yet somehow entirely predictable.

I have been periodically deleting my tweets for a while now. Yesterday, I finally found a reliable solution for deleting my Twitter “likes” as well and I spent some time deleting all of them. Long ago, I also deleted all of my content on Facebook and Instagram. If you are interested in purging your social media accounts, here are some options.

Oakland has been anything but normal over the past year during the pandemic. But we are starting to see glimpses of normality. Little by little, the whole country is returning to “business as usual”, as they say. And the first real indication that normality is on the horizon for the US was a recent story out of Arkansas.

This post is mostly for posterity, for anyone currently experiencing these bugs on macOS, and to praise Titanium Software’s excellent Mac utility app OnyX.

The Touch Bar on my MacBook started freezing and experiencing UI glitches recently. It was completely unresponsive. At the time, the only way I knew to fix it was to reboot my entire machine, which felt ridiculous. Luckily, there is a better way.

I’ve written about my web host before. I’ve used NearlyFreeSpeech.net for years. It’s very “bare bones”, very DIY, and very no-bullshit. I highly recommend them, especially if you only need to host a static site. It is so inexpensive you could say it’s nearly free.

Earlier this year, I decided to re-implement analytics for my site after discovering a viable privacy-aware (and open-source!) alternative to the user-hostile spyware garbage that we call Google Analytics. I have really enjoyed using GoatCounter and I highly recommend it. Now that I have this data, I thought it would be fun to share my top 10 most popular posts in 2020.

Continuing my (still somewhat recent) tradition, here are the books I read in 2020. You can find previous years under the #reading-list tag. I really thought I was going to be able to read a lot more this year, but fuck this pandemic and fuck 2020 all around. There were many weeks where I simply could not focus on much of anything.

Today I cleaned up my various projects and todo’s in OmniFocus. I am always collecting links and resources for potential project ideas, or for general learning. Sometimes, however, it is best to acknowledge that I will likely never have enough free time to even begin some of these endeavors.

As a brief follow-up to my previous post, I thought it would be helpful to enumerate the various types of “self” in Swift. It is an overloaded term. As we’ve seen, it can be quite confusing.

In JavaScript, this pattern is called an Immediately Invoked Function Expression (IIFE) or a Self-Executing Anonymous Function. Swift doesn’t have an “official” name for this, but IIFE works as well as “immediately executed anonymous closure” or “self-executing anonymous closure”. (Thanks to folks on Twitter for helping with this.)

This is a first for me. I returned to my MacBook after leaving it for a couple of hours, and it was shutdown even though I left it powered on. The machine was idle. I didn’t have any specific tasks running. I figured it might have been a macOS kernel panic, but upon rebooting I discovered that the crash was caused by bridgeOS.

Last month, the largest strike in history occurred in India, breaking the record for the second time.

This is a quick follow-up to my previous post. The client project I’m working on is also using Bitrise for CI, which I must say is quite good. If you are looking for a hosted CI service I would highly recommend checking them out.

For a client project that I’ve been working on, I recently integrated Danger to automate pull requests for the team. I initially setup a single Dangerfile to run on CI, but soon after we had the need to split it up in order to run danger more than once for a single CI run.
