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
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

Since then, GitHub has evolved its MySQL architecture to meet the scaling and resiliency needs of the platform—includi
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. A decade ago, I joined EC2 networking team, and it was a fantastic ride. Then, five years back, I heard about Lambda. I really liked the simplicity of the idea. We run your code in the cloud, no servers needed, so I joined

On July 5, 2023, Meta launched Threads, the newest product in our family of apps, to an unprecedented success that saw it garner over 100 million sign ups in its first five days. A small, nimble team of engineers built Threads over the course of only five months of technical work. While the app’s production launch had been under consideration for some time, the business finally made the decision a
A Journey Into Shaders
This article is interactive: you can play with the code and sliders to interact with the shaders. Enjoy! What if I told you that it could takes just few lines of code to create graphics as simple as gradients or as complex as rain effects? Welcome to the world of shaders! I’ve been fascinated by shaders for a couple of years, but each time I attempted to dive into the subject, I felt like I was le

Questionable Advice: “My boss says we don’t need any engineering managers. Is he right?”
I recently joined a startup to run an engineering org of about 40 engineers. My title is VP Engineering. However, I have been having lots of ongoing conflict with the CEO (a former engineer) around whether or not I am allowed to have or hire any dedicated engineering managers. Right now, the engineers are clustered into small teams of 3-4, each of which has a lead engineer — someone who leads the

It's one of those anachronisms that is deeply embedded in modern technology. From cloud operator servers to embedded controllers in appliances, there must be uncountable devices that think they are connected to a TTY.

Look-up-tables, more commonly referred to as LUTs, are as old as Mathematics itself. The act of precalculating things into a row or table is nothing new. But in the realm of graphics programming, this simple act unlocks some incredibly creative techniques, which both artists and programmers found when faced with tough technical hurdles. We’ll embark on a small journey, which will take us from simp

New Workers pricing — never pay to wait on I/O again09/28/2023 Today we are announcing new pricing for Cloudflare Workers and Pages Functions, where you are billed based on CPU time, and never for the idle time that your Worker spends waiting on network requests and other I/O. Unlike other platforms, when you build applications on Workers, you only pay for the compute resources you actually use. W

Picat is a research language intended to combine logic programming, imperative programming, and constraint solving.

Properly Testing Concurrent Data Structures Jul 5, 2024 There’s a fascinating Rust library, loom, which can be used to thoroughly test lock-free data structures.

The goal here isn’t to teach you what y
One happy Rails World
Celebrating twenty years of Ruby on Rails with more than 700 happy developers packed into the coolest conference venue possible in Amsterdam was epic. Safe to say, Rails World was a roaring success. Which is deeply satisfying to conclude, because it really wasn't a given outcome when I started working on The Rails Foundation last year. It's hard to know how new institutions are going to be receive

1. はじめに NeRF (Neural Radiance Field) とは、複雑なシーンに対して、任意の視点からの3次元的なシーンを画像から再構成する技術です。以下の動画にあるように、物体に対して、様々な角度から見たときのシーンをキレイに再現することができます。反射に関しても、それぞれの角度から見たときの見え方が反映されており、角度によって同じ場所でも微妙に違う反射特性を見て取ることができます。この手法を利用して、例えば、地点AとBで画像を取得した場合、その中間地点の任意の角度から対象物体を見たときのシーンを生成可能です。 この記事では、このNeRFと呼ばれる技術と、それを実行するにあたって必要な周辺の技術について簡単にまとめたいと思います。以下に示す、NeRFの論文と照らし合わせてながら解説を行います。しかし、本記事では、NeRFを実行するまでの流れを示すため、各要素技術に関しては詳

How an Elon Musk PAC is using voter data to help Trump beat Harris in 2024 election

The man can hear the gunshots and people screaming in the background. As Trump is rushed off stage with blood
