LLMによるコード補完の登場 (2021年) GitHub Copilotの登場 我々がよく知るLLMによる支援はまず GitHub Copilot から始まりました。これはGPT-3 (OpenAI Codex, 現在のCodexと名前が同じで本当にややこしい) をベースとしたコード補完システムで、タイピングをしていると自動的にその行の続きを予測してくれるものです autocompleteとの違い それ以前にもIntelliSenseのようなautocompleteがありましたし、より進歩したn-gramなどを用いたものはありましたが、LLMをベースとしたものはTabnine (Tabnineは初期はn-gramモデル) やCopilotからとなります チャットベースのコードアシストの時代 (2022-2023年) ChatGPTの登場 ChatGPT以降、チャットによる対話形式でコード
何年後かの自分へ こんにちは、のんピ(@non____97)です。 業務で使用する新しいMacが届きました。 新しいMacを初期セットアップするにあたって「今の設定どうだったっけ...」と調べる時間が結構かかってしまいました ということで何年後かの自分がまた新しいMacに乗り換える際に手間取らないように、設定した内容を書き記しておきます。 移行先のMacの情報は以下の通りです。M1 Max、嬉しい。 # OSのバージョンの確認 > sw_vers ProductName: macOS ProductVersion: 12.4 BuildVersion: 21F79 # カーネルのバージョン確認 > uname -r 21.5.0 # CPUのアーキテクチャの確認 > uname -m arm64 # CPUの詳細確認 > sysctl -a machdep.cpu machdep.cpu.

Introducing Ezno
Ezno is an experimental compiler I have been working on and off for a while. In short, it is a JavaScript compiler featuring checking, correctness and performance for building full-stack (rendering on the client and server) websites. This post is just an overview of some of the features I have been working on which I think are quite cool as well an overview on the project philosophy ;) It is still
A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog
copilot-explorer
Copilot Internals | thakkarparth007.github.io Github Copilot has been incredibly useful to me. It can often magically read my mind and make useful suggestions. The thing that surprised me the most was its ability to correctly “guess” functions/variables from surrounding code – including from other files. This can only happen, if the copilot extension sends valuable information from surrounding cod

Programming is an iterative process. As much as we would like to come up with the perfect solution from the start, it rarely works that way. Good programs often begin as quick prototypes. While many experiments remain prototypes, the best programs can evolve into production code. Whether you’re writing games, CLI tools, or designing library APIs, prototyping helps tremendously in finding the best
Today we’re excited to announce the release of TypeScript 5.2! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by making it possible to declare and describe types. Writing types in our code allows us to explain intent and have other tools check our code to catch mistakes like typos, issues with null and undefined, and more. Types also power TypeScript’s edi

When people say “debuggers are useless and using logging and unit-tests is much better,” I suspect many of them think that debuggers can only put breakpoints on certain lines, step-step-step through the code, and check variable values. While any reasonable debugger can indeed do all of that, it’s only the tip of the iceberg. Think about it; we could already step through the code 40 years ago, sure

Most of my readers are probably familiar with procedural programming, object-oriented programming (OOP), and functional programming (FP). The majority of top programming languages on all of the language popularity charts (like TIOBE) support all three to some extent. Even if a programmer avoided one or more of those three paradigms like the plague, they’re likely at least aware of them and what th
I thought it would be fun to go outside of my comfort zone of web development topics and write about something completely different and new, something I have never written about before. So today, I'm going to show you how to implement a programming language! The project will parse and execute programs written in a simple language I called my (I know it's a lame name, but hey, it is "my" language).
How to Bypass Cloudflare in 2023: The 8 Best Methods - ZenRows
About 1/5 of websites you need to scrape use Cloudflare, a hardcore anti-bot protection system that gets you blocked easily.

This is my opinionated syntax primer for the Lean programming language.

This paper reflects work done in late 2022 and 2023 to audit for vulnerabilities in terminal emulators, with a focus on open source software.

The exact context and severity of these vulnerabilities varied, but some

I did this in 2020 and then again in 2021, but I’m in the mood to look around again. Let’s look through Are We GUI Yet? and see what’s up these days. The task today is to have a text label and an input field that can change the text in the label. In React, for example, this is basically free: const Demo = () => { let [state, setState] = useState("Hello, world!"); return ( <div> <p>{state}</p> <inp
This year’s Advent of Code has been brutal (compare the stats of 2023 with that of 2022, especially day 1 part 1 vs. day 1 part 2). It included a problem to solve with dynamic programming as soon as day 12, which discouraged some people I know. This specific problem was particularly gnarly for Advent of Code, with multiple special cases to take into account, making it basically intractable if you
In 2006 Microsoft conducted a customer survey to find what new features users want in new versions of Microsoft Office. To their surprise, more than 90% of what users asked for already existed, they just didn't know about it. To address the "discoverability" issue, they came up with the "Ribbon UI" that we know from Microsoft Office products today. Office is not unique in this sense. Most of us ar

The Rust programming language feels like a first generation product. You know what I mean. Like the first iPhone - which was amazing by the way. They made an entire operating system around multitouch. A smart phone with no keyboard. And a working web browser. Within a few months, we all realised what the iPhone really wanted to be. Only, the first generation iphone wasn't quite there. It didn't ha
PySkyWiFi: completely free, unbelievably stupid wi-fi on long-haul flights | Robert Heaton
The plane reached 10,000ft. I took out my laptop, planning to peruse the internet and maybe do a little work if I got really desperate. I connected to the in-flight wi-fi and opened my browser. The network login page demanded credit card details. I fumbled for my card, which I eventually discovered had hidden itself inside my passport. As I searched I noticed that the login page was encouraging me
Understanding the core class design and usage via its evolution Years ago, my studies into the Ruby Evolution started with the persuasion that mastering the programming language to express one’s intentions clearly and efficiently may grow significantly by understanding how it evolved and what intentions were put behind its various elements.

You must know the power of Object-oriented programming if you have ever worked with object-oriented languages like Java, C#, and much more. Python also supports object-oriented programming, and we can define a class in Python. Let’s explore more about how to achieve this in Python.

Hash functions are incredibly neat mathematical objects. They can map arbitrary data to a small fixed-size output domain such that the mapping is deterministic, yet appears to be random. This “deterministic randomness” is incredibly useful for a variety of purposes, such as hash tables, checksums, monte carlo algorithms, communication-less distributed algorithms, etc, the list goes on. In this art
