pthread_attr_getstacksize problem
Recently, the company encountered a thread stack size problem, and I took this opportunity to learn about the functions related to the thread stack size. If the company still uses older code, it uses the pthread library to support threads instead of the thread class in C++11. There are mainly two related functions: pthread_attr_setstacksize() and […]

C language minesweeper game (implementing custom size, mine mark, expansion)
Minesweeper is one of the classic games. Now we use C language to implement a simple version of the minesweeper game, which requires the use of loops, arrays, functions and other aspects of knowledge. First, we need a chessboard In the code, use * to replace the grid on the chessboard. The picture below is […]
p5.js canvas operation practice: create, bind specified elements, dynamically adjust size, hide scroll bars, delete canvas
Article Introduction Previously, I briefly talked about how to use p5.js to create a canvas in “Introduction to p5.js Lightspeed”. This time I will introduce several canvas-related methods provided by p5.js. Related configuration when creating canvas. Lets the canvas bind the specified element. Resets the canvas size. Delete the canvas. Before studying this article, you […]
Set the database to start with spfile by default, and set the database SGA size to 2G and PGA size to 200M.
Check the database default startup file first: SELECT value FROM v$parameter WHERE name = ‘spfile’; It can be seen that the database defaults to SPFILE startup Use the following command to check whether the current session is using SPFILE or PFILE: First, set the MEMORY_TARGET parameter to 0. This will ensure that Oracle does not […]
