I don&rsquo;t memorize syntax or worry about code. I just tell the AI what I want and run what it generates.&rdquo; That brief post sent shockwaves through the developer community, and &ldquo;vibe coding&rdquo; has since become one of the hottest terms in software development heading into 2026.</p> https://blog-8ye.pages.dev/en/posts/best-programming-language-2026/ Thu, 16 Apr 2026 09:00:00 +0900 https://blog-8ye.pages.dev/en/posts/best-programming-language-2026/ <p>&ldquo;Which programming language should I learn?&rdquo; It&rsquo;s a question every developer has faced at some point. There&rsquo;s no single right answer, but <strong>there is clearly a better choice depending on your purpose</strong>. Here&rsquo;s an honest comparison of the most relevant languages in 2026.</p> <p><figure><img class="my-0 rounded-md" loading="lazy" decoding="async" fetchpriority="low" alt="2026 Programming Language Ecosystem Map — bubble chart visualizing ecosystem scale and primary domains for major languages" src="https://blog-8ye.pages.dev/images/posts/best-programming-language-2026/svg-1-en.svg" ></figure> </p> <hr> <h2 class="relative group">Python — The Undisputed #1 in the AI Era <div id="python--the-undisputed-1-in-the-ai-era" class="anchor"></div> <span class="absolute top-0 w-6 transition-opacity opacity-0 -start-6 not-prose group-hover:opacity-100 select-none"> <a class="text-primary-300 dark:text-neutral-700 !no-underline" href="#python--the-undisputed-1-in-the-ai-era" aria-label="Anchor">#</a> </span> </h2> <p>Python has essentially monopolized the AI/ML ecosystem. PyTorch, TensorFlow, LangChain, transformers — every major AI library is written in Python. Its concise syntax makes it accessible to beginners, and interactive development through Jupyter Notebooks accelerates experimentation.</p> https://blog-8ye.pages.dev/en/posts/ai-coding-assistant-copilot-best-practices-and-troubleshooting/ Mon, 30 Mar 2026 14:51:00 +0900 https://blog-8ye.pages.dev/en/posts/ai-coding-assistant-copilot-best-practices-and-troubleshooting/ <p><figure><img class="my-0 rounded-md" loading="lazy" decoding="async" fetchpriority="low" alt="A pipeline diagram visualizing the code generation process of an AI coding assistant. &lsquo;Context Collection&rsquo;" src="https://blog-8ye.pages.dev/images/posts/ai-coding-assistant-copilot-best-practices-and-troubleshooting/svg-1-en.svg" ></figure> </p> <p>Recently, AI coding assistants such as GitHub Copilot, Cursor, and Tabnine have become indispensable tools in developers&rsquo; daily lives. From writing simple boilerplate code to drafting complex algorithms, AI dramatically improves development productivity. However, uncritically accepting code suggested by AI can lead to unexpected and serious problems.</p> <p>Phenomena like hallucinations calling non-existent libraries, generation of code containing security vulnerabilities, and short-sighted code suggestions that ignore the overall system architecture are factors that developers must be aware of and vigilant about. An AI coding assistant is not a &lsquo;magic wand&rsquo; but a powerful &lsquo;power tool&rsquo; that requires control.</p> https://blog-8ye.pages.dev/en/posts/implement-gzip-decompressor-in-rust/ Fri, 27 Mar 2026 23:59:36 +0900 https://blog-8ye.pages.dev/en/posts/implement-gzip-decompressor-in-rust/ <p>This English edition walks through the same implementation ideas as the Korean post: parse the Gzip container, read the DEFLATE bitstream, rebuild Huffman tables, replay LZ77 back-references, and verify the footer. The goal is not to compete with production libraries, but to understand the moving parts clearly enough to implement a working decompressor yourself.</p> <p><figure><img class="my-0 rounded-md" loading="lazy" decoding="async" fetchpriority="low" alt="Overview of the Gzip container with header, DEFLATE payload, and footer." src="https://blog-8ye.pages.dev/images/posts/implement-gzip-decompressor-in-rust/svg-1-en.svg" ></figure> </p> <p><strong>What you will learn</strong></p> https://blog-8ye.pages.dev/en/posts/web-job-scheduling-automation-guide/ Fri, 27 Mar 2026 17:47:53 +0900 https://blog-8ye.pages.dev/en/posts/web-job-scheduling-automation-guide/ <p><figure><img class="my-0 rounded-md" loading="lazy" decoding="async" fetchpriority="low" alt="Diagram comparing the flow of a typical web request (User Click → Server API Call → Data Processing → Response) side-by-side with a job scheduling flow (Scheduler Waiting → Scheduled Time Reached → Background Job Runs → Log Recorded), with each step connected by arrows." src="https://blog-8ye.pages.dev/images/posts/%ec%9b%b9%ec%97%90%ec%84%9c-%ec%9e%91%ec%97%85-%ec%8a%a4%ec%bc%80%ec%a4%84%eb%a7%81-%ea%b5%ac%ed%98%84%ed%95%98%ea%b8%b0-%ed%9a%a8%ec%9c%a8%ec%a0%81%ec%9d%b8-%ec%9e%90%eb%8f%99%ed%99%94-%ea%b0%80%ec%9d%b4%eb%93%9c/svg-1-en.svg" ></figure> </p> <p>When running a web application, there are inevitably background tasks that need to be executed periodically, independent of user requests. Typical examples include aggregating database statistics every midnight, sending regular newsletters to users at specific times, or periodically synchronizing data from external APIs.</p>
