  • Based on Mozilla website, on Mac, using the tab key for changing the focus is disabled by default for Firefox and Safari. To enable it for testing you can follow the below steps:
    • Firefox for the Mac doesn't do tabbing by default. To turn it on, you have to go to Preferences > Advanced > General, then uncheck "Always use the cursor keys to navigate within pages". Next, you have to open your Mac's System Preferences app, then go to Keyboard > Shortcuts, then select the All Controls radio button.
      • If you weren't able to find that radio button in mac preferences, then instead you can check the option  'Use keyboard navigation to move focus between controls' in your Mac system preferences>keybord>shortcuts. After this reopen Firefox again and you must be able to use the tab key for tabbing
    • Safari doesn't allow you to tab through links by default; to enable this, you need to open Safari's Preferences, go to Advanced, and check the Press Tab to highlight each item on a webpage checkbox.

  • Install

    • I needed a swap (about the same size of my RAM memory with the flag of linuxswap).
    • It is better to use different partitions for / (root - 66560 MB) and /home. Then I can easily format the / and my personal files wont change.
    • If you install your dual linux in a separate hard (bios legacy), choose the first hard to install the new linux boot loader (No need to a new separate boot partition for the new linux).
    • Linux uses Grub (2) menu to create boot loader menu
    • GPT (UEFI) vs bios legacy: GPT is modern and new. My laptop didn't support GPT well. For gpt must have /boot/efi (Fat32 - 512MB - with flags: boot, eps, bios-grub).
    • Fast boot boot from the main hard so the usb wont load at boot time.
    • If ubuntu's resolution is not correct

  • Convert some images to a PDF file: sudo convert -auto-orient -quality 65 img1.jpg img2.jpg img3.jpg result.pdf

apps

  • Cairo clock for ubuntu
    • To create an automatically execute shell script at startup boot
    • Create /etc/systemd/system/my-cairo-clock.service

ExecStart=/usr/local/bin/disk-space-check.sh

[Install]
WantedBy=default.target
    • Create /usr/local/bin/initial-cairo-clock.sh
    #!/bin/bash
cairo-clock
    • sudo chmod 755 /usr/local/bin/initial-cairo-clock.sh
    • systemctl daemon-reload
    • systemctl enable my-cairo-clock.service

  • Save vim as sudo when you have not opened it with sudo: :w !sudo tee %
    • Colon (:) indicates we are in Vim’s ex mode
    • Exclamation (!) mark indicates that we are running shell command
    • sudo and tee are the shell commands
    • Percentage (%) sign indicates all lines from current line

      • distributionUrl=gradle-6.3-bin.zip

    • I opened the android folder of the project with android studio and tried to run and build it. It installed some stuffs.

    • in the project folder: cd android && ./gradlew clean

  • For using lerna with react-native: I added some lines to metro.config.js

const path = require('path');

// react-native >= 0.57
const extraNodeModules = {
   '@myMonoRepo/test1': path.resolve(__dirname + '/../test1/'),
};
const watchFolders = [
   path.resolve(__dirname + '/../test1/')
