weird Big Sur things: zsh
h | grep | build
and nothing; zsh history only give you the last last 10 commands, history 1 gives you all the saved commands. Confusing?
Just stick this in your .zprofile
alias ll='ls -lG'
alias h='history 1'

emacs Universal build Intel x86_64 and arm64
emacs Intel, arm build
If you just want to install gnu emacs for macos and get going Emacs for MacOSX is the place to go.
I did the builds on my early-2015 mbp with Big Sur 11.6.
- read https://github.com/caldwell/build-emacs
- download build scripts
I didn't install xcode.
xcode-select --install (installs command line tools)
install macports
sudo port install xz
./fetch-emacs-from-ftp -v ftp://ftp.gnu.org/gnu/emacs/
# port install xz
# if you need to convert xz to bz2
# xzcat -c emacs-27.2.tar.xz | bzip2 > emacs-27.2.tar.bz2
./build-emacs-from-tar -v emacs-27.2.tar.bz2 release
Success:
Built Emacs-27.2-11.6-x86_64.tar.bz2, Emacs-27.2-11.6-x86_64-extra-source.tar
- CODESIGN crash
- ./combine-and-package -v --sign "Common Name" Emacs-27.2-11.6-arm64.tar.bz2
- replace "Common Name" with the name in the keychain access login cert.
- see: code signing issue #103
- Success! Thanks Emacs for MacOSX!
TODO:
Go back to the MBP and try the codesign step.
Download Xcode 13 xip

I went on a search for Xcode which is on the App Store but also just downloadable:

Building Audacity on m1 apple silicon
Building Audacity on m1 apple silicon
Don't bother with all the stuff below. Audacity is now available as an arm64 m1 native binary. The x86_64 version works great too! Great work developers!
DONE
Visit 1
- install macports for Big Sur 11.5.2
- sudo port install audacity
- Success, kind of, version 2.2.2 popped out in glorious Apple Silicon binary but I couldn't get the current 3.0.4.
- pull request BUILDING.md typo, correction:
cmake -GXcode -T buildsystem=1 -Daudacity_use_mad="off" -Daudacity_use_id3tag=off ../audacity
- check out audacity source
git clone https://github.com/audacity/audacity
-
sudo pip3 install conan - activated venv using py-env
- master v3.1.0 failed check out 3.0.4
git clone -b release-3.0.4 --single-branch https://github.com/audacity/audacity
- cmake and Xcode
cmake -GXcode -T buildsystem=1 ../audacity
open Audacity.xcodeproj
- rm -rf build/*
- run cmake again:
cmake -GXcode -T buildsystem=1 -Daudacity_use_mad="off" -Daudacity_use_id3tag=off ../audacity
DO
Using python3 venv virtual environment:
BLOCKED
conan install failing(use py-env)- source blocked for m1 compile;
- downloaded branch beta 12.2 wxwidget not included
- wxwidget build error
Xcode does not build master branch 3.1.0 or 3.0.4- 3.0.4 builds then crashes immediately (Intel)
First, doing anything on an external USB3 hard drive is painfully slow compared to the blisteringly fast internal ssd. macports took over an hour to install.
I
think macports is finally falling behind since most sites talk about
brew (meh). Macports has been working great so far.
I wish m1 virtual machine time was 3cents/hr

Updated my 2020 Apple m1 mac mini model A2348 with Big Sur 11.5.2
- mystery update no release notes
- see the excellent eclecticlight blog for more info
- blaaaaarrgh whaaaaaaa: the update bar on reboot looked frozen. ugh. Five minutes later the text appeared with a time estimate, whew!
- please can't some big brains at apple reduce the SIZE of these updates? How about 300MB?
- RESULT: everything seems fine so far

Visiting Nix package manager and Rocket
Nix, NixOS, Rust
An enthusiast gives it a spin+
I used to visit NixOS once a year; I did it every year from 2010-12 then stopped. Things have progressed immensely but I don't have a home application for what NixOS does. If you don't have need of a reliably reproducible system its like trying to drive a zamboni wrapped in plastic wrap. And why it's not. There's a live cd give it a whirl.
How refreshing to discover Xe and her website. Here's how she uses Nix (package manager) and NixOS:
I have the configuration for my shell, emacs, my window manager and just about every program I use on a regular basis defined in their own NixOS modules so I can pick and choose things for new machines.
As an example of devotion to NixOS see the highly entertaining: ianthehenry.com
I am going to try to replicate Xe's example on the Windfall System.
Windfall Computer Part 3
...Previously
Installed virtualbox on the Road Pooter.
VirtualBox Guest Additions failing to install.
launch powershell in admin mode
../VBoxManage [more stuff here]
google around. this is the stuff I wanted to avoid ugh.
Virtualbox working great on the Windows 10 host. Installed the NixOS livecd image with Plasma. Looks very very slick. Installing Debian Buster 10 so I can try the Nix package manager.
Next time, install:
VirtualBox Guest Additions on Debian Buster 10
Let Debian vm get an IP address from DHCP
Windfall Computer Part 2
...Previously
- installed 2x4GB sticks DDR3L RAM and Ubuntu 20.04
DDR3L RAM low(er) voltage so uses less power
Doing almost anything on Linux requires some amount of sudo apt update get install.
- reverted to Windows 10 H21
unknown SMB bios device
no setup DVD-iso on ASUS siteAsus H81M-K audio driver:
Asus H81M-K audio driver:
Windfall Computer Part 1
Covered in dust and leaves; on the sidewalk a black tower pc. Free. Hmmm.
Quality Corsair case. Plastic retention clips brittle with age. What was inside?
- Asus H81M-K motherboard
- i7-4790 cpu (85W TDP)
- stock Intel heatsink and fan
- quiet case fans
- 8GB DDR3 RAM
I had hit the jackpot! Free on the street but Windows 10 install fails. ubuntu install fails. Ran memtest86+ for hours and then found bad RAM.
