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

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
