It moves the Java version into a .github/.java-version file, configures setup-java to read that file, and adds a custom regex manager in renovate.json to update the file. The approach allows local development with the latest JDK while preserving compatibility with older Java versions for targeting and testing. ### Source excerpt You want to be using the latest JDK for development. Don't use Gradle toolchains, they'll needlessly force you to use old JDKs. You can still target and test on old JVM versions but develop with the latest and greatest. Java and the JDK are literally built for this. Locally this hasn't been a problem. Homebrew (or your favorite equivalent) will keep your default JDK at the latest. Keeping my GitHub actions up-to-date, however, frequently slips my mind. I find projects using 19 or 20 simply because I haven't touched the CI build in the two years since 19 or 20 was the latest. We're already using Renovate to keep dependencies up to date. With a little extra programming in JSON (wince) we can have the JDK version updated to latest as well. First, migrate the existing build JDK version in your GitHub Action to a .github/.java-version file1. 21 Next, change the setup-java action to use this file rather than a hard-coded version. - uses: actions/setup-java@v4 with: distribution: 'zulu' - java-version: 21 + java-version-file: .github/.java-version Finally, in your renovate.json52, add a custom manager to update this file3. ignorePresets: [ // Ensure we get the latest version and are not pinned to old versions. 'workarounds:javaLTSVersions', ], customManagers: [ // Update .java-version file with the latest JDK version. { customType: 'regex', fileMatch: [ '\\.java-version$', ], matchStrings: [ '(?.*)\\n', ], datasourceTemplate: 'java-version', depNameTemplate: 'java', // Only write the major version. extractVersionTemplate: '^(?\\d+)', }, ], Commit, push, and wait for Renovate to send you a PR4. Now your CI build automatically tracks the latest JDK. I'm putting the .java-version file into the .github/ folder because I don't want to force this version on people using jenv or the like. The whole point of this setup is you can build with any version of Java newer than our very, very old baseline of Java 8 (although things like Gradle have a higher minimum ## Mac Setup for Web Development \[2026\] DevFeed: [Mac Setup for Web Development \[2026\]]() Original publisher: [Read original article]() Author: Robin Wieruch Published: 2025-01-07T04:50:46Z Content type: tutorial Language: en Sources: [Robin Wieruch]() Topics: [Web Development](), [macOS](), [Homebrew](), [vs-code](), [Zsh](), [Git](), [Node.js](), [ssh](), [JavaScript](), [TypeScript](), [Astro](), [React]() Tags: [2026](), [astro](), [development](), [git](), [js](), [mac](), [mac-setup-javascript](), [mac-setup-web-developer](), [mac-setup-web-development](), [macos](), [node-js](), [react](), [ssh](), [typescript](), [vs-code](), [web-development]() ### AI overview A practical 2026 Mac setup guide for full-stack web development, covering macOS preferences, hardware, Homebrew, terminal tools, VS Code, Git, SSH, and Node.js with NVM. ### Source excerpt My complete Mac setup for web development in 2026: macOS preferences, Homebrew, iTerm2, Oh My Zsh, VS Code, Git, SSH, and Node.js with NVM. ## Open source mac apps I love DevFeed: [Open source mac apps I love]() Original publisher: [Read original article]() Author: Stanko Published: 2024-11-09T00:00:00Z Content type: article Language: en Sources: [Stanko Tadić]() Topics: [Open Source](), [App](), [GUI](), [Homebrew](), [dropbox](), [keyboard]() Tags: [apps](), [bash](), [dropbox](), [gui](), [keyboard](), [mac](), [open-source](), [optimization](), [tools]() ### AI overview The article recommends a selection of free, open-source Mac applications that the author uses regularly, including menu-bar utilities, image optimization software, keyboard customization, clipboard management, Dropbox access, terminal integration, window tiling, and command-line tools.

It downloads the blog's JSON feed, checks for new posts, compares them with a local CSV record of previous toots, and publishes announcements. The article also gives Homebrew installation and execution commands. ### Source excerpt Every time I create a new post in this blog I like to toot or tweet about it. Instead of manually doing this, I have my Mac Mini run a little shell script on a cron job, that does this automatically for me. You can download the source for this script over at github. The way it works is pretty simple: Download my latest blog feed as a json file. Check for any new blog posts. Compares with a local CSV file that records previous toots. Posts new toots to Mastodon1 Running the script is trivially easy (and it's all in Kotlin) so it's easy to follow the logic. All you need to do to run this script is: brew install kotlin kotlin tootbot.main.kts That's it! Just remember to update the variables at the top of the file.

It covers changing the default shell, preserving Bash history, fixing Homebrew path access, configuring persistent environment settings, and defining aliases. ### Source excerpt Pizza courtesy of Pizza for Ukraine! Donate Now to Pizza for Ukraine As I've written, I'm acutely interested in using software written in Rust as my daily drivers. What I've seen so far is that programs written in Rust, based on an admittedly tiny sample, seem to be higher quality than programs not written in Rust. In this blog post, I'm going to talk about what I had to do to make NuShell be usable for myself under OSX Monterey. To be perfectly honest, I don't know if my experiences are normal or not. I seem to have a high personal level of entropy with respect to software and it appears that at least sometimes this level of entropy causes bugs. This is the main reason that I document things so dogmatically - I often need to refer to my own blog. Step 00: Changing Your Shell to NuShell After you install NuShell, you are left a bit on your own. You can invoke it via the nu command but what you really want is it to come up as the default shell. This is done with chsh: sudo chsh -s /usr/local/bin/nu sjohnson NOTE: DO NOT CLOSE ALL YOUR OLD TERMINALS!!! If you are like me and are heavily reliant on history then you want to do this in an existing Bash / Zshell / Fish / Whatever terminal window: history > ~/history_old.txt chmod +r ~/history_old.txt Yes - I think that strongly about history that I want this read only so it doesn't get killed inadvertently. Step 01: Getting Brew to Function After you switch over to using NuShell, you may find that programs like brew aren't found. This is a path issue (isn't everything???). Here's an example: /Users/sjohnson/Sync/coding/flow_analytics〉brew 07/17/2022 10:59:12 AM Error: nu::shell::external_command (link) x External command ╭─[entry #11:1:1] 1 │ brew - ──┬─ - ╰── can't run executable ╰──── help: No such file or directory (os error 2) The solution is to add brew's path into the NuShell environment.

The author reports that bulk permission changes fixed the problem, while warning that the approach is risky and should be used at the reader's own risk. ### Source excerpt NOTE: I'm not telling you to do this. This blog post advocates bulk permission changing and that's risky but HomeBrew was entirely broken and brew doctor did not work. And this solution did. Use at your own risk. I have two primary machines - a Mac Desktop and a dual monitor Mac Laptop. I use the laptop more mostly from habit but I'd really like to use the desktop for something that makes me feel better about it being next to me and yet rarely used. One of the reasons for two machines is one is my daily driver and one is experimental. For example, my desktop I installed NuShell on recently as I didn't (yet) trust it enough. I recently discovered that HomeBrew wouldn't install things correctly on my desktop. The issue was always permissions issues and when I dug into it, I found that /usr/local/Cellar was owned by, well, NOT me. The answer, as with so many other *nix things is chown (DO NOT DO THE FOLLOWING): sudo chown -R sjohnson:wheel /usr/local/Cellar -or- that's what I thought the answer was.

The article documents updating Elixir on macOS, installing Phoenix, generating a Phoenix application with MySQL, configuring the database, and adapting migrations for an existing schema. ### Source excerpt In my last blog post, I dug into Elm and while I like a number of things conceptually about Elm, the process of implementing nothing more than a maybe 8 element HTML form left me hugely frustrated and annoyed. I also didn't like the way that Elm bundles code and display into one thing. I may be a traditionalist perhaps but the separation of views and code really does work well in practice. I get that Elm is a different thing but it shouldn't be this hard to just put some text and an html form on the screen. And, so, I'm putting Elm to the side for a bit and going to experiment with using Elixir and Phoenix for my previous Laravel application. If nothing else this should be much more straightforward as it is moving from one MVC style framework to another albeit from an OO lang (php) to a functional lang (elixir). Step 1: Getting Up To Date I'm on OSX and my goal was to get to the current Elixir and Phoenix before I started, This I found to be surprisingly problematic. And, perhaps, it was my fault as I don't claim to be great with HomeBrew. I started with: brew update brew install elixir@1.12 But no matter what I did, I couldn't get past elixir 1.11. So my next step was to get rid of everything. Getting Rid of Everything I started with: brew uninstall elixir And then I got a warning about a shallow copy issue which told me to run: git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow brew update brew install elixir which finally resulted in: ❯ elixir -v Erlang/OTP 24 [erts-12.3.1] [source] [64-bit] [smp:16:16] [ds:16:16:10] [async-threads:1] [jit] [dtrace] Elixir 1.13.3 (compiled with Erlang/OTP 24) Installing Phoenix A bit of googling gave me this command to install the newest Phoenix: mix archive.install hex phx_new Step 2: Generating a New App Although I've actually been to ElixirCon, things have changed a lot in a few years.

Theoretically you should be able to look at just the upgrade tree with: brew deps --tree --include-build elixir and only those things will be upgraded but when I noted a much larger group of packages being upgraded which makes me suspect some kind of circular dependency that needed to be handled. Fourth check the version again: elixir -v ## macOS Setup after 15 Years of Linux DevFeed: [macOS Setup after 15 Years of Linux]() Original publisher: [Read original article]() Published: 2021-12-25T23:00:00Z Content type: article Language: en Sources: [Dennis Felsing]() Topics: [macOS](), [Homebrew](), [Linux](), [cpu]() Tags: [command-line](), [homebrew](), [intel](), [linux](), [macos]() ### AI overview A developer describes moving from a long-established Linux desktop setup to using an M1 Pro MacBook Pro as a daily driver. The article discusses the hardware, Homebrew installation choices, ARM64 compatibility issues with mpv, and video playback performance using Rosetta 2, Firefox, and a custom FFmpeg build. ### Source excerpt About 3 years ago I wrote about my Linux Desktop Setup and having used pretty much the same software setup for 10-15 years. My setup used to be heavily keyboard based. Now for work I am for the first time using a macOS-based Macbook Pro with an M1 Pro CPU. I spent the last 3 weeks using it as a daily driver, tweaking it here and there. Here are my experiences. Hardware-wise the machine is great. With the 10 core ARM64 CPU I get about 2-3 times the CPU performance of my desktop system with an Intel i7 6700k. In DDNet I can reach 1800 FPS which is clearly more than enough and about 10 times the FPS I have with the 6700k's iGPU. I haven't heard the fan turn on at all yet, so either my workloads, and even my compilations, are too light-weight, or the fan is pretty quiet. The integrated 120 Hz screen is far better than anything I've had before, with clearer colors and smoother motion. Installing Software macOS's AppStore doesn't seem to have most of the relevant applications for me. Homebrew seems to be the most popular third-party package manager for macOS, so I chose that, hoping that it would support most programs I want to use. Command line applications can be installed with brew install, while graphical applications that you want acccessible in the regular Applications directory need a brew install --cask. For some applications like mpv this can be a bit confusing since there is both a command-line Formulae and a GUI Cask available for it. The Cask doesn't support arm64 natively yet, since the maintainer of it doesn't have an M1 Mac and mpv doesn't provide official binaries. So here I noticed a major difference in how Homebrew seems to work compared to Arch Linux for example. On Arch Linux applications are built from source code centrally instead of relying on binaries from a vendor. Luckily it was easy enough to build a DMG of mpv myself, which I then installed by dragging it into the Applications folder: git clone https://github.com/mpv-player/mpv cd mpv git clean ## Homebrew - uninstall formula with dependencies DevFeed: [Homebrew - uninstall formula with dependencies]() Original publisher: [Read original article]() Author: Tom Published: 2021-11-05T00:00:00Z Content type: tutorial Language: en Sources: [Tomasz Gągor]() Topics: [Homebrew](), [macOS]() Tags: [bash](), [brew-autoremove](), [clean-uninstall-homebrew](), [command](), [dependencies](), [disk-space](), [homebrew](), [homebrew-uninstall-dependencies](), [how-to](), [macos](), [macos-brew-tips](), [macos-package-management](), [packages](), [remove-homebrew-formula]() ### AI overview A tutorial on uninstalling a Homebrew formula and its dependencies on macOS.

It covers installation on Mac OS and Linux, the two-pass detection and transformation workflow, and commands for creating vertically stacked or side-by-side comparison videos. ### Source excerpt Way back in Dec 2015, @maxogden wrote a nice guide on stabilizing your own video with ffmpeg. I return to it on occasion and have updated my gist comment to offer some updated commands. Since enough has changed regarding installation and use, I figure a new, spiffy, and working guide deserves a non-gist home. Presenting the 2021-era guide to pretty easy DIY video stabilization! On Mac OS, install ffmpeg and vidstab from homebrew: 1 2 brew install ffmpeg brew install libvidstab On linux, you can sudo make install. Run stabilization in two passes There are plenty of options for libvidstab, like shakiness, accuracy, smoothing. The defaults are good, but you may want to experiment. There's even a visual diagnostic mode. Assuming the source video is named clip.mkv... 1 2 3 4 5 6 # The first pass ('detect') generates stabilization data and saves to `transforms.trf` # The `-f null -` tells ffmpeg there's no output video file ffmpeg -i clip.mkv -vf vidstabdetect -f null - # The second pass ('transform') uses the .trf and creates the new stabilized video. ffmpeg -i clip.mkv -vf vidstabtransform clip-stabilized.mkv You now have a clip-stabilized.mkv! Bonus: create a comparison video Use the vstack or hstack filter, depending on if you want them stacked vertically or side-by-side: 1 2 3 4 5 # vertically stacked ffmpeg -i clip.mkv -i clip-stabilized.mkv -filter_complex vstack clips-stacked.mkv # side-by-side ffmpeg -i clip.mkv -i clip-stabilized.mkv -filter_complex hstack clips-sxs.mkv Double bonus: A two-liner that does everything (because repeating these filenames gets annoying) 1 2 export vid="sourcevid.mkv" ffmpeg -i "$vid" -vf vidstabdetect -f null -; ffmpeg -i "$vid" -vf vidstabtransform "$vid.stab.mkv"; ffmpeg -i "$vid" -i "$vid.stab.mkv" -filter_complex vstack "$vid.stacked.mkv" ## Programming the ESP8266 on an M1 Mac DevFeed: [Programming the ESP8266 on an M1 Mac]() Original publisher: [Read original article]() Published: 2021-02-16T17:30:00Z Content type: tutorial Language: en Sources: [Rambo Codes]() Topics: [ESP8266](), [Arduino](), [Microcontrollers](), [Homebrew](), [Programming]() Tags: [arduino](), [esp8266](), [homebrew](), [microcontrollers](), [programming]() ### AI overview This article explains how to program an ESP8266 microcontroller with the Arduino Pro IDE on an M1 Mac.

I've had a development system for Phoenix and Elixir since at least 2016 but I haven't done much. This means that the first task is bringing it into the 2020s. Upgrading Elixir I installed Elixir via HomeBrew which means it is a simple: which elixir /usr/local/bin/elixir Note: It can be hard sometimes to know if you installed things via HomeBrew and checking their location is an easy cheap as HomeBrew installs stuff to /usr/local/bin And then: brew upgrade elixir And then: elixir --version Erlang/OTP 23 [erts-11.0.3] [source] [64-bit] [smp:16:16] [ds:16:16:10] [async-threads:1] [hipe] [dtrace] Elixir 1.10.4 (compiled with Erlang/OTP 23) You can also use just -v: elixir -v Erlang/OTP 23 [erts-11.0.3] [source] [64-bit] [smp:16:16] [ds:16:16:10] [async-threads:1] [hipe] [dtrace] Elixir 1.10.4 (compiled with Erlang/OTP 23) Upgrading Mix and Hex Mix and Hex give the equivalent of a build tool (like Rake from the Rails world) and a Package Manager (like Gem / Bundler). To upgrade mix, you use: mix local.hex Found existing entry: /Users/sjohnson/.mix/archives/hex-0.20.5 Are you sure you want to replace it with "https://repo.hex.pm/installs/1.10.0/hex-0.20.5.ez"? [Yn] Y * creating /Users/sjohnson/.mix/archives/hex-0.20.5 And that will upgrade both mix and hex. Upgrading Phoenix The phoenix framework version I have dates back to 1.2 or 1.3 I think. The first step is to figure out what version I have: mix phoenix.new --version Phoenix v1.3.3 The method to upgrade the Phoenix framework itself is: mix archive.install hex phx_new 1.5.4 I used a google query to discover that the current Phoenix framework version was 1.5.4. The other way to find this version number is to go to this url: https://hexdocs.pm/phoenix/installation.html And then look at the drop down of different versions in the left hand sidebar. The latest version is always at the top.

It explains that a stale postmaster.pid file can make Homebrew falsely report PostgreSQL as running, and recommends verifying that PostgreSQL is stopped before removing the file and restarting the service. ### Source excerpt I've recently had the situation where my personal development box (OSX Mojave, Rails, Postgres) has become unstable with, at times, multiple crashes per day. I logged in this morning and found myself getting errors like this: PG::ConnectionBad (could not connect to server: No such file or directory) I did some digging and even though Postgres appeared to be running to brew, it was a false positive due to a leftover postmaster.pd file. Here was the fix: First make sure that postgres isn't running use ps i.e. **ps auwwx grep post**. Delete the file: /usr/local/var/postgres/postmaster.pid i.e. rm /usr/local/var/postgres/postmaster.pid At this point brew will, foolishly and oddly, still think Postgres is running so do do a brew restart postgres Here's a handy Stack Overflow reference. Note: Make absolutely sure that postgres is NOT running before you delete postmaster.pid or you risk serious database corruption / data loss. [Next page]()
