サーバー環境などを構築する場合、構築後にサーバーが想定どおりに動作するかをテストするために、サーバーに意図的に負荷を掛けたいときがあります。 そのようなとき、テストの対象がWindowsマシンなら、Microsoftから無償提供されてい負荷ツールが便利です。 そこでここでは、WindowsマシンでCPU／メモリ／ディスクに負荷をかけるツールと、その利用方法を紹介します。 CPUに負荷を掛けるCPUに負荷を掛ける場合は、開発者・管理者向けのトラブルシューティングツール「Windows Sysinternals」で提供されている「CPUSTRES」を利用します。 ツールは以下からダウンロードできます。 CpuStres - Windows Sysinternals | Microsoft Docs ダウンロードしたZipファイルを解凍し、OS環境に応じたファイルを実行します。 32ビットOSな
Gmailと米国Yahoo!のあれ(2024年2月) - /var/lib/azumakuniyuki
メールシステム担当の人はもちろん、インフラ担当の人もDNSの設定とかで既に知ってはると思いますが、 10月にGoogleが発表した2024年2月から始まるGmailとYahoo!(米国)におけるスパム対策強化のあれです。 海外では数年前から"No Auth, No Entry"って「代表なくして課税なし」みたいな感じで言われているアレです。 識者の方々がいろんなところで記事にしてはりますので、他のところであんまり書かれていない気がするとこだけ記します。 まずは公式情報 Google Googleについては以下の二ヶ所を読んで理解して実践しておけば大丈夫そうです、たぶん。 パラメーターのhl=enをhl=jaに変えると日本語版になりますが、更新されるのが遅いので最初に英語版を見ておくのが良いです。 Email Sender Guidelines(81126) Email Sender Gui
Do You Really Need Redis? How to Get Away with Just PostgreSQL
Do You Really Need Redis? How to Get Away with Just PostgreSQL There’s a tried-and-true architecture that I’ve seen many times for supporting your web services and applications: PostgreSQL for data storage Redis for coordinating background job queues (and some limited atomic operations) Redis is fantastic, but what if I told you that its most common use cases for this stack could actually be achie
大実験！ChatGPTは競プロの問題を解けるのか (2024年5月版) - E869120's Blog
1. はじめに 2024 年 5 月 14 日、OpenAI 社から新たな生成 AI「GPT-4o」が発表され、世界に大きな衝撃を与えました。これまでの GPT-4 よりも性能を向上させただけでなく1、音声や画像のリアルタイム処理も実現し、さらに応答速度が大幅に速くなりました。「ついにシンギュラリティが来てしまったか」「まるで SF の世界を生きているような感覚だ」という感想も見受けられました。 しかし、いくら生成 AI とはいえ、競技プログラミングの問題を解くのは非常に難しいです。なぜなら競技プログラミングでは、問題文を理解する能力、プログラムを実装する能力だけでなく、より速く答えを求められる解法 (アルゴリズム) を考える能力も要求されるからです。もし ChatGPT が競技プログラミングを出来るようになれば他のあらゆるタスクをこなせるだろう、と考える人もいます。 それでは、現代最強の
GPT-4, GPT-3.5 の API を利用して JSON だけ生成する (Function calling)
先日 OpenAI API のアップデートが以下のように発表されました。 一番の注目は Function calling じゃないでしょうか？ 名前から「関数を呼び出せるのかな？」と一番最初に想像しちゃいますが、この機能の革新的な部分は「JSON を作成してくれる」ところだと思っています。 JSON を作れると嬉しいことがいっぱいありますね！ ダミーデータの作成 生成した JSON をそのままレスポンスとして返すエンドポイントの作成 テストとしても良い 関数や外部 API の呼び出し 今までは難しかった JSON の作成 今まで、JSON を作成してもらうにあたって gpt-3.5-turbo を用いて JSON を作成させようとするとほぼ失敗していました。それで gpt-4 のモデルを利用して JSON を作成させますが、このモデルはほとんど正確になる一方で処理速度がかなり遅くなる点がネ

AWS Lambda Under the Hood
Transcript Danilov: We'll talk about AWS Lambda, how it's built, how it works, and why it's so cool. My name is Mike Danilov. I'm a Senior Principal Engineer at AWS Serverless.

Build a CQRS event store with Amazon DynamoDB | Amazon Web Services
AWS Database Blog Build a CQRS event store with Amazon DynamoDB The command query responsibility segregation (CQRS) pattern, derived from the principle of command-query separation, has been popularized by the domain-driven design community. CQRS architectures that use event sourcing save generated events in an append-only log called an event store. By using event sourcing, you can, among other ben
Distributed systems provide a particular challenge to program. They often require us to have multiple copies of data, which need to keep synchronized. Yet we cannot rely on processing nodes working reliably, and network delays can easily lead to inconsistencies. Despite this, many organizations rely on a range of core distributed software handling data storage, messaging, system management, and co

How are Unix pipes implemented?
This article is about how pipes are implemented the Unix kernel. I was a little disappointed that a recent article titled “How do Unix pipes work?” was not about the internals, and curious enough to go digging in some old sources to try to answer the question. What are we talking about? Pipes are “perhaps the single most striking invention in Unix” — a defining characteristic of the Unix philosoph

SRE for single-tiered software applications | Google Cloud Blog
In cloud operations, we often hear about the benefits of microservices over monolithic architecture. Indeed, microservices help manage hardware being abstracted away and push developers towards resilient, distributed designs. However, many enterprises still have monolithic architectures which they need to maintain. For this post, we’ll use Wikipedia’s definition of a monolith: “A single-tiered sof
