Dev Containerを使ってステップバイステップで作るPythonアプリケーション開発環境 - 電通総研 テックブログ
みなさんこんにちは、電通総研コーポーレート本部システム推進部の佐藤太一です。 この記事では、VS CodeのDev Containerを使ってOSに依存しないPythonの開発環境を構築する方法をステップバイステップで丁寧に説明します。 VS Codeの利用経験があり、またPythonによるアプリケーション開発に興味のある方を想定読者として記述しています。Pythonの初心者から中級者向けを意識して書いていますので、意図して冗長な説明をしています。 すでにPythonによるアプリケーション開発に十分に詳しい方は、まずはまとめだけ読んでみてください。私自身それほどPythonのエコシステムに詳しいわけではありませんので、知識の抜け漏れは恐らくあるでしょう。そういった事に気が付いたら、XなどのSNSでこの記事のURLを付けてコメントをしていただけると幸いです。 はじめに 事前の準備 最小限のD

There are lots of posts trying to show how simple it is to get started with Kubernetes. But many of these posts use complicated Kubernetes jargon for that, so even those with some prior server-side knowledge might be bewildered. Let me try something different here. Instead of explaining one unfamiliar matter (how to run a web service in Kubernetes?) with another (you just need a manifest, with thr
Container Runtime SecurityForbid New PrivilegesYour container should never run as privileged, as this would grant it all root capabilities on the host machine. For enhanced security, it is recommended to explicitly forbid the addition of new privileges after container creation using this option: --security-opt=no-new-privileges. Define Fine-grained CapabilitiesBy default, your containers run with

A Walk with LuaJIT
The following is a chronicle of implementing a general purpose zero-instrumentation BPF based profiler for LuaJIT. Some assumptions are made about what this entails and it may be helpful to read some of our other work in this area. One major change from prior efforts is that instead of working with the original Parca unwinder we are now working with the OpenTelemetry eBPF profiler. If you missed t
Since I was unable to travel for a couple of years during the pandemic, I decided to take my new-found time and really lean into Rust. After writing over 100k lines of Rust code, I think I am starting to get a feel for the language and like every cranky engineer I have developed opinions and because this is the Internet I’m going to share them. The reason I learned Rust was to flesh out parts of t

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

Before that, cloud computing itself took off in roughly 2010 (AWS was founded in 2006); and Agile goes back to 2000 (the Agile Manifesto dates back to 2001, Extreme Programming t
