Gemini CLI Plan Mode

You are Gemini CLI, an expert AI assistant operating in a special 'Plan Mode'. Your sole purpose is to research, analyze, and create detailed implementation plans. You must operate in a strict read-only capacity.

Gemini CLI's primary goal is to act like a senior engineer: understand the request, investigate the codebase and relevant resources, formulate a robust strategy, and then present a clear, step-by-step plan for approval. You are forbidden from making any modifications. You are also forbidden from implementing the plan.

Core Principles of Plan Mode

Strictly Read-Only: You can inspect files, navigate code repositories, evaluate project structure, search the web, and examine documentation.
Absolutely No Modifications: You are prohibited from performing any action that alters the state of the system. This includes:

Use Command as Control in VSCode using the Neovim integration extension

This is a hack to use the Command key as if it's the Control key in macOS within VSCode while using the VSCode-Neovim extension.

Who wants this?

This is a niche requirement for very few people, but I know I'm not alone. Here are some examples of other people in the wild facing a similar problem:

Upscale 1080p to 4k using ffmpeg

Just use the command below:

ffmpeg -i INPUT_FILE \
  -vf scale=3840x2160:flags=lanczos \
  -c:v libx264 \
  -crf 13 \
 -c:a aac -b:a 512k \

Cloning a Ubuntu boot SSD to NVME

Getting short of space on a 120G boot/root SSD on Ubuntu Server, decided to replace it with a bigger NVME (IDE) 250G drive.

Using the latest Clonezilla, the process was really painless. After cloning, there was still over 100G unallocated space on the larger drive for expansion of a new parition. The paritions of the clone had the same disk UUIDs and flags as the original.

Checked disk and partition sizes using lsblk.
Downloaded latest Stable iso from https://clonezilla.org/downloads.php.
Get a 1G or more USB stick and burn the iso onto it using Startup Disk Creator.
Installed the NVME drive onto the motherboard.

scenario: you have a windows vm failing to boot with INACCESSIBLE_BOOT_DEVICE and changing the disk type to ide or something else causes another bsod. how to you get it to boot up again without a physical machine?

download the stable virtio drivers from here, in iso form: https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/stable-virtio/virtio-win.iso

add the iso to your qemu/virt manager config as a cd/dvd drive

windows should send you to the recovery mode screen, but if it doesn't you might have to run a windows install iso to get to it.

Linux Desktop on Apple Silicon in Practice

NOTE: Time flies, and it's been almost five years(!) since I wrote this. Beaware the text below is now outdated (e.g., now Asahi Linux has graphics acceleration even better than this). The commands listed are up-to-date.

I bought M1 MacBook Air. It is the fastest computer I have, and I have been a GNOME/GNU/Linux user for long time. It is obvious conclusion that I need practical Linux desktop environment on Apple Silicon.

Android emulator. Reduce CPU usage on MacOS

I wasn't able to shut the audio off with the config.ini file, but only with the -noaudio cmd line argument to qemu. However, with Android Studio 3.2, you can't add custom arguments to the emulator, so I made this:

In the emulator dir of the Android SDK, in my case ~/Android/Sdk/emulator/

mv emulator emulator.orig Make a bash script called emulator with the content:

#!/bin/bash

	#!/usr/bin/env bash

	# Builds mpv & mpv.app on Apple silicon Macs.
	# Run this script from the root directory of the mpv repo.

	# if anything fails, gtfo
	set -ex

	meson setup build
	meson compile -C build
