It turns out that MacOS Tahoe can generate and use secure-enclave backed SSH keys! This replaces projects like https://github.com/maxgoedjen/secretive

There is a shared library /usr/lib/ssh-keychain.dylib that traditionally has been used to add smartcard support to ssh by implementing PKCS11Provider interface. However since recently it also implements SecurityKeyProivder which supports loading keys directly from the secure enclave! SecurityKeyProvider is what is normally used to talk to FIDO2 devices (e.g. libfido2 can be used to talk to your Yubikey). However you can now use it to talk to your Secure Enclave instead!

Learning VIM in Xcode comes with its own set of challenges and limitations, but there is enough there for you to give your mousing hand a break and master the keyboard.

A limited set of commands are available in Xcode, and this document attempts help ease the learning curve of using VIM in Xcode by providing a handy reference as well as what I find works for me in practice.

NOTE: Commands are case-sensitive. A command of N means pressing shift + n on the keyboard.

This document is a work in progress! Leave a comment if you would like to see a change.

• set -e, -u, -x, -o pipefail
• set -e
• set -x
• set -u
• set -o pipefail
• Setting IFS
• Original Reference

On every machine in the cluster install openmpi and mlx-lm:

conda install conda-forge::openmpi
pip install -U mlx-lm

Next download the pipeline parallel run script. Download it to the same path on every machine:

Standard escape codes are prefixed with Escape:

• Ctrl-Key: ^[
• Octal: \033
• Unicode: \u001b
• Hexadecimal: \x1B
• Decimal: 27

TL;DR

1. Make a copy conhost.exe from System32.
2. Open it with a hex editor (I use HxD).
3. In HxD, go to Search - Find - Hex-values.
4. Search for 881d9e530a004885c07477ff15b32e08009084c0.
5. In Windows 10 version 2004, replace ff15b32e0800 with 909090909090. If using Windows 10 version 20H2, replace ff15b32e08009084 with 9090909090909090.
6. Save file and copy it back to System32 (take ownership of original conhost.exe in order to replace it).
7. Profit!
