Configure iTerm2's Smart Selection for Diff Paths

hi@mangoumbrella.com — Thu, 30 Jul 2026 15:27:42 +0000

When working with diffs in the terminal, for example:

--- a/src/pyrefdev/mapping/pylabel.py
+++ b/src/pyrefdev/mapping/pylabel.py

I often need to copy the path of the file. But double-clicking the path selects a/src/pyrefdev/mapping/pylabel.py by default.

Luckily, you can configure iTerm2's Smart Selection with this regex to only select the path part:

(?<=[-+]{3} [ab]/)\S+

Here is a step-by-step guide:

Go to Settings > Profiles > Advanced > Smart Selection > Edit.
Click the + button.
Set Regular expression to (?<=[-+]{3} [ab]/)\S+.
Set the precision to Very High so it wins over the built-in path rules.

Now a double-click selects just src/pyrefdev/mapping/pylabel.py.

my pet peeve: when parent URLs don't work

for example if your website has a page:

site.domain/path/to/this/page

these pages should always be valid too:

site.domain/path/to/this
site.domain/path/to
site.domain/path

Mango Exposure v2026.2

hi@mangoumbrella.com — Fri, 31 Jul 2026 21:17:25 +0000

Mango Exposure v2026.2 is now available. This one is mostly about sensors.

NEW:

A Release Notes screen in Settings, so the app can tell you what changed without you coming here.
The 1 inch sensor, used by cameras like the Sony RX100 series and most drones.
The 44x33 digital medium format sensor, used by the Fujifilm GFX and Hasselblad X series.
The 53x40 digital medium format sensor, used by the Phase One IQ4 and Hasselblad H series.

CHANGED:

The Four Thirds sensor is now labelled Four Thirds / Micro Four Thirds.
The APS-C Sony/Nikon/Pentax sensor now mentions Fujifilm, which uses the same sensor size.

Happy photographing, whatever you shoot with ^_^

Mango Exposure v2026.1

hi@mangoumbrella.com — Sun, 25 Jan 2026 06:45:14 +0000

After 4 months of deliberation, I have decided to adopt Liquid Glass in Mango Exposure v2026.1. Why? Because Apple told me to.

Anyway, happy photographing no matter where you are ^_^

hi@mangoumbrella.com — Mon, 05 Jan 2026 03:37:40 +0000

Somehow my fastlane upload pipeline stopped working, due to shadowing the system rsync binary.

I would have never guessed this root cause.

Historically it would take me hours of debugging and head banging, but Opus 4.5 just did it under one minute by itself.

Found it! You have a Homebrew rsync (3.4.1) that's being used instead of Apple's built-in openrsync:

which rsync → /Users/mango/tools/brew/bin/rsync (Homebrew 3.4.1)

/usr/bin/rsync → Apple's openrsync (protocol 29)

Xcode's export process is mixing these two incompatible versions, causing the "syntax or usage error" when they try to communicate.

Sequoia National Park

hi@mangoumbrella.com — Sat, 03 Jan 2026 16:54:01 +0000

In the afternoon before our spontaneous road trip to Sequoia National Park, I discovered a bulge on the front right tire. I immediately called my repair shop Menlo Atherton Auto Repair, and thanks to Anthony, we were able to depart before noon the next day. We stayed for two nights in Three Rivers, close to the south entrance.

The view at our AirBnb in Three Rivers

The first 20 miles entering the park are steep with numerous switchbacks. I drove much more slowly, but with frequent turnouts along the road, it was a pleasantly relaxing experience.

Landscapes in the Sequoia National Park

Snow appeared once we entered the Giant Forest. On a holiday during winter, the parking space near General Sherman are accessible spots only. So we took the shuttle service instead. It ran quite frequently. On the way back to Three Rivers, we saw a spectacular sunset.

2025 has been the weirdest year so far, and 2026 is going to be weirder.

I’m not prepared for this. But 2025 has truly taught me preparedness is overrated.

When there is a high mountain in front of you, just climb on with your heart. And I’m more ready than ever to continue climbing.

Thank you Myke Hurley and Jason Snell for awarding Mango Baby the Best iOS App of 2025 🤯

Being an Upgrade listener for 11 years+, I can't express how honored I feel right now. Mango Baby was made from my heart when I was a new parent. And reading the overwhelmingly positive messages from my users, including Myke(!), has kept me going with this app. Thank you. ❤️

2024 was so painful, but looking back I’m quite glad it happened.
