The Ultimate Git Alias Setup

If you use git on the command-line, you'll eventually find yourself wanting aliases for your most commonly-used commands. It's incredibly useful to be able to explore your repos with only a few keystrokes that eventually get hardcoded into muscle memory.

Some people don't add aliases because they don't want to have to adjust to not having them on a remote server. Personally, I find that having aliases doesn't mean I that forget the underlying commands, and aliases provide such a massive improvement to my workflow that it would be crazy not to have them.

The simplest way to add an alias for a specific git command is to use a standard bash alias.

# .bashrc

taoyuan

# npm using https for git
git config --global url."https://github.com/".insteadOf git@github.com:
git config --global url."https://".insteadOf git://

# npm using git for https
git config --global url."git@github.com:".insteadOf https://github.com/
git config --global url."git://".insteadOf https://

Ubuntu 16 default python is almost python 3

Loads of solutions exist, but for changing the system default, alias is not the way to go.

$ update-alternatives --list python update-alternatives: error: no alternatives for python

  // ILI9341 reads data pins when WR rises from LOW to HIGH (A1 pin on arduino)
  PORTC = PORTC & B11111101; // WR 0
  
  // data pins of ILI9341 connected to two arduino ports
  PORTD = (PORTD & B00000011) | ((d) & B11111100); 
  PORTB = (PORTB & B11111100) | ((d) & B00000011); 
  
  PORTC = PORTC | B00000010; // WR 1
}

Flash instruction:

The only way to flash LEDE image in TL-WR902AC v3 is to use tftp recovery mode in U-Boot:

1. Configure PC with static IP 192.168.0.66/24 and tftp server.
2. Rename "openwrt-ramips-mt76x8-tplink_tl-wr902ac-v3-squashfs-tftp-recovery.bin" to "tp_recovery.bin" and place it in tftp server directory.

	# Make the content
	echo "Generating root content.."
	mkdir files
	echo "$(date)" > files/date.txt
	echo "Another content" > files/other.txt

#These config are based by Nand device that you will use!

How to connect a Raspberry Pi to a WPA2 Enterprise Network

tags: Auburn, Auburn University, WPA2, WPA2 Enterprise

Auburn University is gracious enough to provide instructions to Ubuntu users on how to connect their hosts to the Auburn University WiFi Network.

Many Universities use WPA2 Enterprise authentication on their networks. This allow you to track WHO is connected where and have granular control over who's able to access the WiFi network.

For tinkerers and experimenters with Raspberry Pi, Particle Photon, and other embedded systems, this poses a problem because many simplier IoT devices do not support WPA2 Enterprise natively or not without some hassle.

Raspbian Jesse and earlier will display a WPA2 Enterprise network from its dropdown list, but it will be greyed out. The workaround is to manually connect to it:
