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
Sublime Text 4
The first stable release of Sublime Text 4 has finally arrived! We've worked hard on providing improvements without losing focus on what makes Sublime Text great. There are some new major features that we hope will significantly improve your workflow and a countless number of minor improvements across the board. A huge thanks goes out to all the beta testers on discord and all the contributors to
This blog tries to summarize all the choices and paths you could take to implement your next programming language, more specifically the frontend for your language. There are a lot of factors that will influence your choices. Maybe you have your favorite host language that you would like to use for implementing your language, whether your language is dynamically or statically typed, or you are des
前回の記事ではじめてPineconeを使いました。Pineconeについて、もう少し詳しく知りたいと思ったので、公式ドキュメントを読んで内容をまとめました。基本的には分かりやすい概念が多いのですが、1つだけ難しいなと思った概念がでてきたので、サンプルとともに説明します。 ベクトルデータベースとは 機械学習では、文章、画像、音声、動画などのあらゆるデータを、特徴を抽出したベクトルに変換して扱うことが多いです。ベクトルは、数百から数千の次元の数値として表現されます。ベクトルデータベースは、このような特殊なデータ構造を持つデータを扱うために作られたデータベースです。 ベクトルデータベースを使うことで、ベクトル間の類似性を高速に検索することができます。これによって、文章のセマンティック検索、画像・音声・映像などの類似検索、ランキングやレコメンド、重複検出、異常検出、などに応用することができます。

Processing large JSON files in Python without running out of memory
Processing large JSON files in Python without running out of memory by Itamar Turner-Trauring Last updated 06 Jan 2023, originally created 14 Mar 2022 If you need to process a large JSON file in Python, it’s very easy to run out of memory. Even if the raw data fits in memory, the Python representation can increase memory usage even more. And that means either slow processing, as your program swaps
Google Cloud Champion Innovators Advent Calendar 2024 の 12 日目の記事です。 はじめに LLM が広く普及し、活用範囲が急速に拡大してきたことで、ツール連携機能を活用した AI エージェントを構築する機会も増えてきています。このような LLM とツールの連携により、チャットインターフェースから様々なシステムやサービスを制御・自動化できるようになりました。 しかし、AI エージェントの開発には2つの困りごとがあると感じています。1つ目は、複雑な指示を処理するために必要な高性能モデルの応答速度が遅い点、2つ目は複数のプロジェクトでツールを再利用する際の実装効率の問題です。 本記事では、これらに対する解決策の一例を紹介します。LLM から BigQuery を操作するユースケースにおいて、応答速度が遅い点については Gemini 2.0

Python is a powerful programming language that provides many packages that we can use. Using the versatile Python programming language, we can develop the following: AutomationDesktop applicationAndroidWebIoT home automationData Science and the list goes on.In this article, our primary focus will be knowing how to start learning Python and the essentials required to be a data scientist. Below is t
I stumbled over Bart de Goede’s article on building a full-text search engine in 150 lines of Python, and was reminded of my quest to show how useful Haskell is for solving real-world problems. Python is an eminently practical language, so nobody is surprised this can be done in Python. But Haskell? The Python code spends a lot of time updating mutable dictionaries. Surely we cannot easily port th
Introduction: Density Is King (With a Tiny VM) I've previously come to the conclusion that there's little reason for using bytecode in the modern world, except in order to get more compact code, for which it can be very effective. So, what kind of a bytecode engine will give you more compact code? Suppose I want a bytecode interpreter for a very small programming environment, specifically to minim

Packing up the household for a recent move, I was delving into shoeboxes, photo albums, and file folders that had not been opened in decades.

A mega tutorial with dozens of examples on how to use the pathlib module in Python 3 When I started learning Python, there was one thing I always had trouble with: dealing with directories and file paths! I remember the struggle to manipulate paths as strings using the os module. I was constantly looking up error messages related to improper path manipulation. The os module never felt intuitive an

Java in the Small Java has many features that make it well suited for large, long-lasting projects. But I find it surprisingly good for small tasks as well. Recent language features make it even better. The killer features are compile-time typing and great tool support. This article also appeared in the Java Advent calendar.

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

In Data Science, we primarily use Python as a programming language to perform operations on the available datasets. This article will discuss concepts and details for using Pythons to simplify data operations in data science. Pros and Cons of Python for Data OperationsEven though the pros outweigh the cons, it is crucial to look at both aspects. So, let’s have a look at the advantages and limitati
