Raspberry pi: how to find raspberry pi model details

In the raspberry pi console type: 

 pinout

output:

,--------------------------------. | oooooooooooooooooooo J8 +==== | 1ooooooooooooooooooo | USB | +==== | Pi Model 3B V1.2 | | +----+ +==== | |D| |SoC | | USB | |S| | | +==== | |I| +----+ | | |C| +====== | |S| | Net | pwr |HDMI| |I||A| +====== `-| |--------| |----|V|-------' Revision : a02082 SoC : BCM2837 RAM : 1024Mb Storage : MicroSD USB ports : 4 (excluding power) Ethernet ports : 1 Wi-fi : True Bluetooth : True Camera ports (CSI) : 1 Display ports (DSI): 1 J8: 3V3 (1) (2) 5V GPIO2 (3) (4) 5V GPIO3 (5) (6) GND GPIO4 (7) (8) GPIO14 GND (9) (10) GPIO15 GPIO17 (11) (12) GPIO18 GPIO27 (13) (14) GND GPIO22 (15) (16) GPIO23 3V3 (17) (18) GPIO24 GPIO10 (19) (20) GND GPIO9 (21) (22) GPIO25 GPIO11 (23) (24) GPIO8 GND (25) (26) GPIO7 GPIO0 (27) (28) GPIO1 GPIO5 (29) (30) GND GPIO6 (31) (32) GPIO12 GPIO13 (33) (34) GND GPIO19 (35) (36) GPIO16 GPIO26 (37) (38) GPIO20 GND (39) (40) GPIO21


This commands returns few important information like Model and revision of the raspberry pi, Memory, SoC, Wifi/Bluetooth, and Pin ports detail.

How to push changes to github after password authentication is deprecated

I tried to check-in some code to my github repository after more than 6 months today. I found that normal username and password for authentication does not work anymore. Instead I had to use Personal access token (PAT).

There's a simple step to generate PAT. Keep the code secure in a secure place as it will be required to push the change to the git. 

Create a token in github:

1) login to github site. 

2) on the top right corner, Click user icon.

3) on the dropdown menu,  select Settings.

4) click on Developer settings 

5) Select Personal Access token. 

6) Click Generate new token. And follow the instruction. 

7) select required permissions. 

Use token to push code:

1) Open console and locate the source folder. Run the code below: 

git push https://<GITHUB_ACCESS_TOKEN>@github.com/<GITHUB_USERNAME>/<REPOSITORY_NAME>.git
Example: 
git push https://[email protected]/sanjeeb/myproject2.git
