Docker commands

 Was trying to create a docker for android. Here are the commands I used:

* sudo apt-get install qemu-kvm

* curl -fsSL https://get.docker.com -o get-docker.sh

* sh ./get-docker.sh

*docker run -d -p 6080:6080 -e EMULATOR_DEVICE="Samsung Galaxy S10" -e WEB_VNC=true --device /dev/kvm budtmo/docker-android:emulator_13.0

* sudo chmod 666 /var/run/docker.sock 

(if permission denied in previous step)

* docker ps

* docker stop <NAME>

Date conversion in MySQL

With recent release, MySQL throws error when inserting dates. This is because, by default "strict mode" is enabled. To get rid of the errors, we need to do something as follows:

SHOW VARIABLES LIKE 'sql_mode';

set sql_mode='';

Installing IBC (Interactive Broker Controller)

 This is a nice utility to keep ibkr TWS running. These are the commands :

$ wget https://github.com/IbcAlpha/IBC/releases/download/3.20.0/IBCLinux-3.20.0.zip

$ sudo unzip IBCLinux-3.20.0.zip -d /opt/ibc

$ sudo chmod o+x /opt/ibc/*.sh /opt/ibc/*/*.sh

$ cat ~/ibc/config.ini

     IbLoginId=<username>

     IbPassword=<password>

$ rm IBCLinux-3.20.0.zip
