Windows Operating System by default has a control panel since early versions of Windows such as Windows 3.x, but it only shows most frequent options and it hides some options. Enable the “God Mode” of Control Pane It is quite simple to enable the “God Mode” which shows everything e.g. all the options in one window. Step 1: Go to Desktop, right click to make a new folder Step 2: Rename the folder as the following: GodMode.{ED7BA470-8E54-465E-825C-99712043E01C} That is it! The folder will be automatically changed to a shortcut to the “God Mode” of Control Panel, and the icon will Continue Readin ..read more

Teaching Kids Programming: Videos on Data Structures and Algorithms There is an undirected tree with n nodes labeled from 0 to n – 1 and n – 1 edges. You are given a 2D integer array edges of length n – 1 where edges = indicates that there is an edge between nodes ai and bi in the tree. You are also given an integer array restricted which represents restricted nodes. Return the maximum number of nodes you can reach from node 0 without visiting a restricted node. Note that node 0 will not be a restricted node. Continue Reading » The post Teaching Kids Programming – Reachable Nodes With Restrict ..read more

This post shows you 3 interesting/fun BASH commands: BASH Console Tetris Game You can now play tetris game in Bash console. You would need to install this via: $ sudo apt install bastet # or sudo yum install bastet ## start the Tetris Game $ bastet Control the movement of Tetris blocks by the direction keys. BASH CMatrix This shows the Matrix animation. To install, run the following command: $ sudo apt install cmatrix # or sudo yum install cmatrix ## start the cmatrix $ cmatrix This can be used as a cool screen saver.

In the center of Cambridge, England, there is a Raspberry Pi store inside The Grand Arcade shopping center. This is one of only two offline Raspberry Pi stores in the UK (official website), the other Raspberry Pi shop is in Leeds. The address of the Raspberry Pi store in Cambridge is: SU46, The Grand Arcade, St Andrew’s St, Cambridge CB2 3BJ This store is quite clean. My wife dragged me there to go shopping. She wanted to buy clothes, which is very tiring for me as I’m just a mobile clothes rack. However, she promised to take me to this Continue Reading » The post Visiting The Raspberry Shop i ..read more

Teaching Kids Programming: Videos on Data Structures and Algorithms Given an array of integers arr and an integer k. Find the least number of unique integers after removing exactly k elements. Example 1: Input: arr = , k = 1 Output: 1 Explanation: Remove the single 4, only 5 is left. Example 2: Input: arr = , k = 3 Output: 2 Explanation: Remove 4, 2 and either one of the two 1s or three 3s. 1 and 3 will be left. Constraints: 1 <= arr.length <= 10^5 1 <= arr <= 10^9 0 <= k <= arr.length Least Number Continue Reading » The post Teaching Kids Programming – Least Number of Unique ..read more

Teaching Kids Programming: Videos on Data Structures and Algorithms You are painting a fence of n posts with k different colors. You must paint the posts following these rules: Every post must be painted exactly one color. There cannot be three or more consecutive posts with the same color. Given the two integers n and k, return the number of ways you can paint the fence. Example 1: Input: n = 3, k = 2 Output: 6 Explanation: All the possibilities are shown. Note that painting all the posts red or all the posts green is invalid because there cannot Continue Reading » The post Teaching Kids Prog ..read more
