Do it now!

오래 전, 라떼 시절 만들었던 파이썬 코드를  Chat GPT를 이용하여 개선해 보았다.

Python 2.X 시절 만든 코드를 3.X로 바꾸면서 저장 기능 까지 추가 하였다.

파이썬 소스 코드를 빌드해서 python.exe  를 만들어 보자

1. 빌드 환경 구성

• Visusal Studio를 설치한다
• Python 3.10버전을 설치한다

2. 파이썬 소스를 다운 받는다 (우리는 3.11을 사용한다)

https://www.python.org/ftp/python/3.11.5/Python-3.11.5.tgz

3. 적당한 폴더에 압축을 푼다

4. 설치경로\PCbuild\build.bat 를 실행한다

5. 잠시 뒤 

설치경로\PCbuild\amd64\python.exe 가 생성 됨을 볼수있다.

주말 동안 C# 을 공부 하기로 하고, 첫 프로그램을 작성해 보았다.

언어을 배우면 누구나 만들어 보는 Word Count 프로그램.

class WordCount
{
    private readonly string fileText;

    WordCount(string fileText)
    {
        this.fileText = fileText;
    }

    private void printInfo()
    {
        var wordCount = getWordCount(fileText);
        var lineCount = getLineCount(fileText);

        Console.WriteLine($"LineCount: {lineCount}");
        Console.WriteLine($"WordCount: {wordCount}");
        Console.WriteLine($"Character Count: {fileText.Length}");
    }

    private int getWordCount(string fileText)
    {
        return fileText.Split(new[] { ' ', '\t', '\n', '\r' }, StringSplitOptions.RemoveEmptyEntries).Length;
    }
    
    private int getLineCount(string fileText)
    {
        return fileText.Split(new[] { '\n' }).Length;
    }
    
    static void Main(string[] args)
    {
        if (args.Length == 0)
        {
            Console.WriteLine("Usage: WordCount [FileName]");    
            return;
        }

        string filePath = args[0];
        if (!File.Exists(filePath))
        {
            Console.WriteLine($"{filePath} not exist!");
            return;
        }

        string fileText = File.ReadAllText(filePath);
        WordCount wc = new WordCount(fileText);
        wc.printInfo();
    }
}

JetBrains 사이트의 공식 설명

https://blog.jetbrains.com/ko/2020/05/18/write-code-faster-using-live-templates-ko/

1. Python 3.10.6 설치 

https://www.python.org/downloads/release/python-3106/

2.  Git 설치

https://git-scm.com/downloads

3. Stable diffusion webui 설치

https://github.com/AUTOMATIC1111/stable-diffusion-webui.git

git clone https://github.com/AUTOMATIC1111/stable-diffusion-webui

4. 모델 다운로드

https://civitai.com/

https://huggingface.co/WarriorMama777/OrangeMixs

모델을 다운 받아서, \stable-diffusion-webui\models\Stable-diffusion 에 넣어 준다.

확장자가 .safetensors 인 것을 받는 걸 추천 한다.

5. 실행

webui-user.bat 를 수행한다. (첫 실행시 이것 저것 설치한다고 시간이 걸린다.)

6. http://127.0.0.1:7860/ 로 웹 브라우저로 접속 하면 된다.

#include <iostream>

const int MAX_SIZE = 10;

void update(int* TREE, int idx, int value) {
    for (++idx; idx <= MAX_SIZE+1; idx += (idx & -idx))
        TREE[idx] += value;
}

int sum(int *TREE, int s) {
    int r = 0;
    for (++s; s > 0; s &= (s-1))
        r += TREE[s];
    return r;
}

int main(int argc, char **argv) {
    int TBL[MAX_SIZE] = {0};
    int TREE[MAX_SIZE+1] = {0, };

    for (auto i = 0; i < MAX_SIZE; i++) {
        TBL[i] = i+1;
        update(TREE, i, TBL[i]);
    }

    // GET SUM from 1 ~ N
    for (auto i = 0; i < MAX_SIZE; i++)
        std::cout << sum(TREE, i) << ", ";
    std::cout << std::endl;
    
    return 0;
}
