  The tic-tac-toe game with Python

In this tutorial, we will show how to build a tic-tac-toe game with Python. We will use functions,arrays,if statements,while statements, for loops and error handling etc. First, we need to create two functions, the first function will display the borad of the game: def print_board(): for i in range(0,3): for j in range(0,3): print map[2-i][j], if j != 2: print "|", print "" Here we used two for loops to loop through the map, this map is...

  Gemini Example with Go

To connect and use Gemini with Go, Google's LLM, one can use their official Go SDK for doing this. In this post, we will just show a simple chat example to demonstrate how to make it work with Go. The example is just to ask the model to translate some English to Chinese and get its output. The code actually looks like: var client *genai.Client // geminiOnce.Do(func() { client, err = genai.NewClient(ctx, option.WithAPIKey(string(apiKey))) if err != nil { log.Fatal(err) } model := client.Genera...

  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...

  Advantages and disadvantages of GoLang

GoLang is a strong typed language which means it is less flexible than interpreted languages by nature. But Go provides Any type(interface) and Reflect mechanism which make the language very close to interpreted languages on flexibility. More and more people start to learn GoLang. This post is mainly for listing down some of the advantages and disadvantages of GoLang. Advantages Performance(Machine code) GoLang is a compilation language which can be compiled to machine code and the compiled bina...

  JavaScript finite state machine

Finite state machine is a very useful design model, it can be used to simulate many events in the world. In short, finite state machine has three features: Number of states is finite At any moment, one object can only be in one state In some condition, it will transfer from one state to another state In JavaScript, finite state machine can be applied in many places. For example, one menu element on a webpage. When the mouse hovers on the menu, the menu will show up, while the mouse moves away...

  Custom C++ exception class creation

In standard C++, we can use try catch to catch and exception when something goes wrong. These are some built in exception support in C++. By including the #include , we can now catch exceptions in C++ programs. This actually helps us on debugging our code and reduce the maintenance work.However sometimes if we want to create our own custom exception class. What should we do?We should include the #include line and then extend the exception class and implement some methods as you like. The genera...

  Go Error Best Practice

Being indulged in Go for quite a while and having implemented web-related programs, grpc interfaces and Operators, I seem to be an advanced beginner now. However, I am still a raw hand in production-environmental debugging, which is cumbersome if done by querying logs or error messages. Imagine the scenario that a full-text search is called when the specific location of the error log is missing. Then what happens when those error logs are not only in one place? Yes, my error logs can no longer h...
