Cookiecutter

Cookiecutter is a command-line tool used to create structured projects from a template. It’s a widely-used tool in the industry and it also support engineers to customize their own templates and share with others. In this post, I would like to.share some basic information about cookiecutter.

What is “tty” in Docker

Many docker-compose.yml files will contain a line tty:true. A lot of engineers only copy this line when they create a new one but few of them actually know what it is for. Why do we need to write it down in our service? Do we really need it? In this post, I’ll explain why we use it and how can we use it.

Introduction

Hey, it’s been a long time since my last post. It’s been a difficult time for me in the past few months and I’m very happy to return to update my blog! Let’s start with a news about Github!

Introduction

eBPF (external Berkerly Packet Filter) is a technology originated in the Linux kernel that can run sandboxed programs in the OS kernel. It provides users with the ability to ingest user-defined program into the OS kernel without modifying the kernel code.

In this post, I will share some basics about eBPF and write a simple eBPF program.

Problem

You are given a 0-indexed m x n binary matrix grid.

In one operation, you can choose any i and j that meet the following conditions:

• 0 <= i < m
• 0 <= j < n
• grid[i][j] == 1

and change the values of all cells in row i and column j to zero.

Return the minimum number of operations needed to remove all 1‘s from grid.

Problem

You are given an m x n binary matrix grid.

In one operation, you can choose any row or column and flip each value in that row or column (i.e., changing all 0‘s to 1‘s, and all 1‘s to 0‘s).

Return true if it is possible to remove all 1‘s from grid using any number of operations or false otherwise.
