関数名、メソッド名、変数名でよく使う英単語のまとめ
プログラミングをしていると関数名、メソッド名、変数名をどうするか悩みます。 ロジックより命名に時間を費やすこともざらにあります。翻訳したり、一般的な命名規則なのかいつも検索して大変です。 よく使うサイトの内容をコピってメモしておく 関数名とメソッド名の違いについて よく使う英単語のまえに、いつもごっちゃにして使っているけど、定義はこんな感じ 「関数」と「メソッド」の違い 似ているところ どちらも何か（引数）を入れると処理をして何か（戻り値）を返してくれます。 違うところ やってること自体は大差ありません。概念としては違います。 メソッドはオブジェクト指向で登場する用語で、オブジェクトの動作を定義したものです。 まずオブジェクトありきなのですね。一方の関数は、オブジェクト云々は関係ありません。 個人的な使い分け Java で登場する関数は「メソッド」です。C 言語で登場する関数は「関数」と呼

January 30, 2023 In this post, we'll implement a GPT from scratch in just 60 lines of numpy. We'll then load the trained GPT-2 model weights released by OpenAI into our implementation and generate some text. Note: This post assumes familiarity with Python, NumPy, and some basic experience with neural networks. This implementation is for educational purposes, so it's missing lots of features/improv
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

Overview エムスリーエンジニアリンググループ AI・機械学習チームでソフトウェアエンジニアをしている中村(po3rin) です。検索とGoが好きです。 エムスリーではChatGPTの可能性にいち早く注目して活用を検討している段階ですが、本格的なデータ投入にはまだ懸念もあり、セキュリティチームと検討を進めている段階です。 そんな中で個人または組織のドキュメントのセマンティック検索と取得を可能にするChatGPTプラグイン「ChatGPT Retrieval Plugin」が登場しました。 github.com 情報検索好きとしては黙っていられず、外部公開用のエムスリーAI・機械学習チームのメンバー紹介ドキュメントを使ってローカルで試してみました。 # 用意したドキュメント 中村弘武は東京都在住で、エムスリーという企業で働いでいます。 エムスリーの検索基盤を主に担当しています。また、書
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).
Python's "Type Hints" are a bit of a disappointment to me

I've incorporated some feedback I got into this revised version. Introduction Over the course of several Python 3.x versions, "type hints" were introduced. You can now annotate functions: def greeting(name: str) -> str: return 'Hello '
Tier 4 Support § Support for these targets is entirely experimental. If this target is provided by LLVM, LLVM may have the target as an experimental target, which means that you need to use Zig-provided binaries for the target to be available, or build LLVM from source with special configure flags. zig targets will display the target if it is available. This target may be considered deprecated by
I want to write a post about Pitchfork, explaining where it comes from, why it is like it is, and how I see its future. But before I can get to that, I think I need to share my mental model on a few things, in this case, Ruby’s GVL. For quite a long time, it has been said that Rails applications are mostly IO-bound, hence Ruby’s GVL isn’t that big of a deal and that has influenced the design of so

Introduction Some part of me has always been fascinated with coercing code to run in weird places. I scratch this itch a lot with my security research projects. These often lead me to writing shellcode to run in kernels or embedded hardware, sometimes with the only way being through an existing bug. For those not familiar, shellcode is honestly hard to describe. I don’t know if there’s a very form
Reading the excellent article by JeanHeyd Meneide on how broken string encoding in C/C++ is made me realise that Unicode is a topic that is often overlooked by a large number of developers. In my experience, there’s a lot of confusion and wrong expectations on what Unicode is, and what best practices to follow when dealing with strings that may contain characters outside of the ASCII range. This a
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

Python behind the scenes #11: how the Python import system works
If you ask me to name the most misunderstood aspect of Python, I will answer without a second thought: the Python import system. Just remember how many times you used relative imports and got something like ImportError: attempted relative import with no known parent package; or tried to figure out how to structure a project so that all the imports work correctly; or hacked sys.path when you couldn

A Deep Dive into eBPF: Writing an Efficient DNS Monitoring.
eBPF / XDP is an in-kernel virtual machine, provides a high-level library, instruction set and an execution environment inside the Linux kernel. It’s used in many Linux kernel subsystems, most prominently networking, tracing, debugging and security. Including to modify the processing of packets in the kernel and also allows the programming of network devices such as SmartNICs. Use cases in eBPF im

Julia 1.0 came out well over 2 years ago. Since then a lot has changed and a lot hasn’t. Julia 1.0 was a commitment to no breaking changes, but that is not to say no new features have been added to the language. Julia 1.6 is a huge release and it is coming out relatively soon. RC-1 was released recently. I suspect we have at least a few more weeks before the final release. The Julia Core team take
Following up from the last post, there is a lot more we need to cover. This was intended to be the post where we talk exclusively about benchmarks and numbers. But, I have unfortunately been perfectly taunted and status-locked, like a monster whose “aggro” was pulled by a tank. The reason, of course, is due to a few folks taking issue with my outright dismissal of the C and C++ APIs (and not showi
I find blockchain fascinating because it extends open source software development to open source + state. This seems to be a genuine/exciting innovation in computing paradigms; We don’t just get to share code, we get to share a running computer, and anyone anywhere can use it in an open and permissionless manner. The seeds of this revolution arguably began with Bitcoin, so I became curious to dril
Python behind the scenes #6: how Python object system works
As we know from the previous parts of this series, the execution of a Python program consists of two major steps: The CPython compiler translates Python code to bytecode. The CPython VM executes the bytecode. We've been focusing on the second step for quite a while. In part 4 we've looked at the evaluation loop, a place where Python bytecode gets executed. And in part 5 we've studied how the VM ex

Decorator JITs - Python as a DSL - Eli Bendersky's website
Spend enough time looking at Python programs and packages for machine learning, and you'll notice that the "JIT decorator" pattern is pretty popular. For example, this JAX snippet: import jax.numpy as jnp import jax @jax.jit def add(a, b): return jnp.add(a, b) # Use "add" as a regular Python function ... = add(...) Or the Triton language for writing GPU kernels directly in Python: import triton im
Exhaustive Union Matching in Python - Preferred Networks Research & Development
Pattern matching on algebraic data types is a powerful technique to process a given input and many programming languages have adopted it in one way or another. A check on whether a given match is “exhaustive”, i.e., covers all possible inputs, is helpful to avoid bugs when the set of possible inputs is extended; for example, when new enumeration values are added. In this blog post I will first bri
UPDATED: 2025-02-15: Fixed some bugs in the examples and pointed out that you don't usually just want to panic on memory allocation failure. I've been writing a lot of Rust recently, and as anyone who has learned Rust can tell you, a huge part of the process of learning Rust is learning to work within its restrictive memory model, which forbids many operations that would be perfectly legal in eith
What does it mean for a BPF application to be portable? And why it's actually hard to achieve that without BPF Compile Once — Run Everywhere (CO-RE)? In this post we'll see what are the challenges of writing BPF programs that can work across multiple kernel versions and how BPF CO-RE is helping to address this problem.

Django for Startup Founders: A better software architecture for SaaS startups and consumer apps
In an ideal world, startups would be easy. We'd run our idea by some potential customers, build the product, and then immediately ride that sweet exponential growth curve off into early retirement. Of course it doesn't actually work like that. Not even a little. In real life, even startups that go on to become billion-dollar companies typically go through phases like: Having little or no growth fo
How to build a plugin system in RustMay 29, 2024Software used by businesses often needs to be extensible. For Arroyo, a real-time SQL engine, that means supporting user-defined functions (UDFs). But how can we support dynamic, user-written code in a static language like Rust? This post dives deep into the technical details of building a dynamically-linked, FFI-based plugin system in Rust.
