An experience of fixing a memory-corruption bug
During the last 4 months, I was disturbed by a memory-corruption bug, and this bug will cause program crash. Until last Monday, I found the root cause and fixed it. This debug process is a difficult but memorable experience, so I will share it in this article. My program works as a SMS Hub. When it receives a SMS, it will allocate a structure in heap memory like this: typedef struct { ...... int *a[8]; ...... } info; After processing the SMS, the program will free the m...

Bug caused by using changeable value as the default in "python method overload"​
In python we can set the passed in parameter's default value to make the function has the same running feature as the method overload in Java. Define a function like this: def testFunction(self, param1, param2=None, param3=None): Normally we use "None" as the parameter's default value. We can also use str/bool as the default value, but is it OK we use empty list [] as its default value? This is our test program: """ A test program using empty list as the passed-in parameter's default value. ...

Disgusting programming language list
To avoid arguments among different programming languages, this ranking only covers the opinions from programmers with multi-language experience. Also it doesn't mean the language is not good if the language is on the list, it just means those developers don't like some features of the language. Below ranking is summarized from Quoraã€Stack Overflow and Hacker News. 10. Python Reason : It uses code indent to define block level scope, why not use curly braces? It also uses massive colons and ...

How Cybersecurity Preparedness Can Minimize Downtime During Cyber-Attacks
According to statistics, the average cost of a data breach reached $4.88 million in 2024, marking the highest recorded average to date. Moreover, 68 percent of data breaches in 2024 involved a human element. Cyber-attacks are no longer rare events—they’re an everyday risk for businesses. When a business isn’t prepared, even a minor attack can lead to costly downtime, disrupt operations, and harm its reputation. The good news is that businesses can reduce these impacts with pro...

How to play with cross domain request
What is cross domain request In simple, cross domain request is to request resource from other domain in one domain. Note, the "other domain" doesn't just mean domain name only, it includes much more. If the protocol, domain name, port is not the same, two domains will be considered different. Below example describes what is considered as different domain. http://www.a.com/a.jshttp://www.a.com/b.js # Same domainhttp://www.a.com/lab/a.js &nb...

Beauty of code : How to write graceful PHP code
Writing good code is an art. In order to achieve this, it is necessary to develop good programming habits at the beginning. Good programming habits not only contributes to the early project design (modular),but also allows you to the code easier to understand, so that the maintenance of the code is easier. Bad programming habits will result in more code bugs, and will make future maintenance work difficult. We introduce some good programming habits taking PHP as example. Hope this will help you....
Calculating Token Count for Claude API Using Go: A Step-by-Step Guide
When working with large language models like Claude from Anthropic, understanding how many tokens your input consumes is essential for managing costs and optimizing performance. In this blog, we’ll explore how to calculate token counts for a given input using Go. We’ll use Anthropic’s count_tokens API endpoint, which provides a straightforward way to determine token usage. Prerequisites Before diving in, ensure you have: A working Go environment (installation guide). An Anthro...

Singleton Pattern in Golang
Singleton pattern is the simplest design pattern in software design. It ensures that only one instance of an object exists globally, regardless of how many times the object is instantiated. Based on the characteristics of the singleton pattern, it can be applied to scenarios such as global unique configuration, database connection objects, file access objects, etc. In Go language, there are multiple ways to implement the singleton pattern. Today, let's learn together about some of these approach...
