speed up oh my zsh launch

Slow Start Up

The first time I launch terminal (which I rarely do) it takes about 10 seconds to finish loading.  Way longer than it should but I didn't bother fixing it.

 

What Really Happened

Still slow, adding the two lines to .zshrc did not fix it. Commented them out.

Added:

export NVM_LAZY=1

Will not fix for now.

 

 

Fix

Launch your Terminal app.  I used the nano editor in Terminal. 

Edit .zshrc

 

nano .zshrc

then copy and paste, the lines below to the end of your .zshrc file

# configure node version manager
export NVM_DIR=~/.nvm [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" --no-use 

# This loads nvm
alias node='unalias node ; unalias npm ; nvm use default ; node $@'
alias npm='unalias node ; unalias npm ; nvm use default ; npm $@'

Solved: bootable ssd big sur m1 apple silicon

Creating bootable external ssd  macos big sur m1 apple silicon

I installed macos Big Sur 11.6.8 on an external 256GB m.2 NVME ssd connected to the Thunderbolt port on an m1 Apple Silicon machine.  I used both the standalone installer downloaded from the App Store and from macos Recovery mode (holding down the power button).

Each time install would fail at the first reboot of the installer.

The install log in the Installer gives a hint:

 bridge device not found 

Problem:

 

The ssd is bus powered; it is not powered up when the installer restarts.

Solution:

The external ssd needs an external power source.  I connected the ssd to a port on a drive dock with its own power brick.  After installation you can plug the external ssd into the Thunderbolt port again.  

In addition, remember to set your internal drive as the startup drive (Apple menu> system prefs>Startup Disk) when you disconnect your external ssd.  Your system may not start correctly if you don't set the startup disk.

This applies to macos Big Sur 11.6.8.

Proxmox on a Laptop

Installing Proxmox on a laptop

Fujitsu Lifebook AH530, i5 bad thermals

DO

• replace thermal paste
  
• SATA II/III SSD.
•  

DONE

• Promox 2 old machine cluster; not enough storage or processing power and uses too much electricity. So not useful.

machine1: i7-4790 8GB RAM

machine2: Core2 Duo E7500 4GB RAM

NOT

• m1 macs won't allow p-h to listen to port 53 (disabling SIP temp fix)
• Do not run on a USB; the high rates of writing will quickly kill the USB.
