Gamedev in Lisp. Part 1: ECS and Metalinguistic Abstraction - cl-fast-ecs by Andrew
Gamedev in Lisp. Part 1: ECS and Metalinguistic Abstraction In this series of tutorials, we will delve into creating simple 2D games in Common Lisp. The result of the first part will be a development environment setup and a basic simulation displaying a 2D scene with a large number of physical objects. It is assumed that the reader is familiar with some high-level programming language, has a gener

This blog post hopes to convince you that Python is a compiled language. And by “Python”, I don’t mean alternate versions of Python like PyPy, Mypyc, Numba, Cinder, or even Python-like programming languages like Cython, Codon, Mojo1—I mean the regular Python: CPython! The Python that is probably installed on your computer right now. The Python that you got when you searched “python” on Google and
一番大きな単位としてデータベース (Database) があり、その中に複数のテーブル (Table) を持つことができ、そのテーブルの中に複数のタイムシリーズ (Time-Series) が入っています。タイムシリーズ (Time-Series) は時系列に並んだレコード (Record) のまとまりとなっていて、その中にディメンション（Dimension）と呼ばれる測定値を識別するための属性情報とメジャー (Measure) と呼ばれる測定値でテーブル内で一意に決まるものに対して、タイムスタンプごとにレコード (Record) と呼ばれる単一のデータポイントが記録されています。 各構成要素の細かい制約はこちらを参照してください。では、Amazon Timestream の基本操作のイメージを掴んでいただくために、Timestream のデータベースとテーブルを作成し、データを挿入後、検

In the two years since I’ve posted I want off Mr Golang’s Wild Ride, it’s made the rounds time and time again, on Reddit, on Lobste.rs, on HackerNews, and elsewhere. And every time, it elicits the same responses: You talk about Windows: that’s not what Go is good at! (Also, who cares?) This is very one-sided: you’re not talking about th
Nx Console VS Code Extension Compromised - StepSecurity
Update: On May 19, 2026, GitHub publicly disclosed that approximately 3,800 of its internal source code repositories were exfiltrated after an employee's device was compromised by a poisoned VS Code extension. While GitHub did not officially name the extension, Nx CEO Jeff Cross confirmed that Nx is working with Microsoft and GitHub on the impact of the malicious Nx Console version 18.95.0, and no
MAI-Thinking-1: Building a Hill-Climbing Machine The Microsoft AI Team 1 Abstract Progress in AI is driven not by a single model, but by the ability to continually improve upon the current state of models.

AIによる自律論文作成プロセス：AI Scientistのプロンプト解説｜genkAIjokyo|ChatGPT/Claudeで論文作成と科研費申請
sakana.aiが発表した「AI Scientist（AI科学者）」が話題ですね。このAI Scientistは、機械学習の分野で新しいアイデアを生み出し、実験を行い、論文を執筆し、さらには論文を査読する一連のプロセスを自動化します。 今回AI Scientistシステムのプロンプトを紹介していきます。論文作成にも活用できると思いますので是非ご覧ください。AIによる研究プロセスの自動化は、私たち研究者の仕事を大きく変える可能性を秘めています。 個人的な着目点 1.アイデア発案と新規性評価 AIがアイデアを生成し、既存論文との比較により新規性を評価する機能は注目に値します。特に、Semantic Scholar APIを用いた論文検索システムが詳細に指示されている点は興味深いです。私の理解ではSemantic Scholar APIは医学系は弱いと思いますが、Pubmed APIはポンコツ

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

Clients and servers are never updated at exactly the same time - even when you try to update them at the same time. One or the other may get rolled back. Don’t assume that you can make a breaking change and it’ll be okay because the client and server are in sync. Don’t Re-use a Tag NumberNever re-use a tag number. It messes up deserialization. Even if you think no one is using the field, don’t re-

Amazon FSx for NetApp ONTAPは単純なファイルサーバーじゃないぞ こんにちは、のんピ(@non____97)です。 皆さんはMulti-AZのEBSボリュームを欲しいなと思ったことはありますか? 私はあります。 EBSボリュームはAZ単位なのでAZ障害のことを考えるとちょっと心配です。かと言って自分でブロックレベルのレプリケーションを実装するのも何だか大変です。 そこで、Amazon FSx for NetApp ONTAPの出番です。 Amazon FSx for NetApp ONTAPはファイルサーバーとしての機能だけではなく、ブロックストレージとしての機能も有しています。 Q: Amazon FSx for NetApp ONTAP はどのプロトコルをサポートしていますか?

Cloud9 で SAM を利用し AWS サービス毎の請求額を毎日 Slack に通知する | DevelopersIO
Cloud9 を利用して AWS のサービス毎の料金を毎日 Slack に通知する仕組みを作成しました。 コーヒーが好きな emi です。 AWSサービス毎の請求額を毎日 Slack に通知するため、以下のブログ AWSサービス毎の請求額を毎日Slackに通知してみた を見ながら設定しようとしたのですが、手元の Windows 11 端末に AWS CLI、AWS SAM CLI、Python などの開発環境を整えるのが面倒…！！と思いました。 そこで、AWS Cloud9 を使って手軽に一時的な開発環境を構築し、AWS Serverless Application Model (SAM) でサーバレス通知システムを構築しました。 AWS Serverless Application Model (SAM) とは AWS SAM は、サーバーレスアプリケーション構築用のオープンソースフレー
An AI-native software engineer is one who deeply integrates AI into their daily workflow, treating it as a partner to amplify their abilities. This requires a fundamental mindset shift. Instead of thinking “AI might replace me” an AI-native engineer asks for every task: “Could AI help me do this faster, better, or differently?”. The mindset is optimistic and proactive - you see AI as a multiplier

Concurrency is not very intuitive. You need to train your brain to consider what happens when multiple processes execute a certain code block at the same time. There are several issues I often encounter: Failing to recognize potential concurrency issues: It's not uncommon for both beginner and seasoned developers to completely miss a potential concurrency problem. When this happens, and the concur
(This is the first of a two part series on rate limiting with Redis.

Introduction: These Aren’t the JSONs You’re Looking For JSON (JavaScript Object Notation) was designed as a simple, lightweight, and human-readable data interchange format, often positioned as a more accessible alternative to XML. It has become the de facto standard for web APIs and system integration. However, while the specification itself is straightforward, different programming languages and
