Basic Mocking with mock_open

The simplest approach is to use mock.mock_open to simulate reading from a file. This method works well when one only needs a single return value.

import unittest
from unittest import mock

    local dry_run=false

    # Local function to display help
    display_help() {
        echo "Usage: ${FUNCNAME[1]} [-h|--help] [-n|--dry-run] [-i|--image IMAGE_NAME]"

How to Generate & Use Private Keys using OpenSSL's Command Line Tool

These commands generate and use private keys in unencrypted binary (not Base64 “PEM”) PKCS#8 format. The PKCS#8 format is used here because it is the most interoperable format when dealing with software that isn't based on OpenSSL.

OpenSSL has a variety of commands that can be used to operate on private key files, some of which are specific to RSA (e.g. openssl rsa and openssl genrsa) or which have other limitations. Here we always use

The snippets found here are a part of the Using Chart.js in Trilium tutorial.

The files should be linked to a render note to work, the video tutorial goes through the setup steps.

Note: The following versions appeared in the tutorial:

• Chartjs version 2.9.3.
• Chartjs Data Labels Plugin version 0.7.0

Recovering WD SA510 Firmware 52015100

Issue

WD SA510 defaults to having firmware version 52015100 which self-destructs itself, preventing further access to the drive and preventing updating it.

Failing Attempts

Following attempts were tried and failed

• Reading the data under Linux (some partitions showed some dir others did not)

Testing in Both Real and Fake Time in Javascript

The code shows how to jump between the fake and real time allowing to:

• Execute real-time dependent stubs (in real time), in this scenario it's the HIL simulation.
• Execute long test in time controlled manner (in fake time), in this scenario it's the HIL test.

Current Implementation

Avoid using await Promise.resolve() by ticking asynchronously, for example using fakeClock.tickAsync() and then you could move between fake and real time, the code is updated to show this solution.

Using a macro to add double quotations over multiple lines in vim

1. Select the Lines of Interest:

   • Move the cursor to the start of the first line where you want to perform the operation.
   • Enter Visual Line mode by pressing Shift+V.
   • Use the up or down arrow keys to extend the selection to cover all lines of interest.

2. Start Recording the Macro:

   • Press q followed by a letter (like a) to start recording the macro into register a.

Nautilus Meld Extension

Overview

This Nautilus extension allows us to easily compare files and directories using the Meld comparison tool directly from the Nautilus context menu.

# One could use vimdiff, meld, or even diff
def diff_with(test_func=None, tool='vimdiff'):
    # The decorator was used with parentheses
    # thus the test_func is not set, we need to call it ourself
    if test_func is None:
