Introduction Kubernetes Operators are processes connecting to the master API and watching for events, typically on a limited number of resource types. When a relevant event occurs, the operator reacts and performs a specific action. This may be limited to interacting with the master API only, but will often involve performing some action on some other systems (this could be either in cluster or of
At Stripe, our product docs are designed to feel like an application rather than a traditional user manual. For example, we incorporate a user's own API test key into code samples, making it possible to copy and paste code that seamlessly works with the user's own account. We have client-side interactivity, like checklists and collapsible sections. We tailor the content to the individual user, con

ノルウェー人がドイツ人に、日本人が中国人に変身 世の中には不思議な病気があるもので、「外国語様アクセント症候群（foreign accent syndrome：FAS）」は、その一例といえます。FASは、たとえばイギリス人がフランス語訛りの英語を話すといったように、同じ母国語を使用する第三者が「外国語のようだ」と違和感を持つような発話になってしまう障害です。その特徴として、音の高低や強弱、リズムなどのイントネーションの異常がみられ、一方で語彙・文法機能はほぼ正常に保たれています。 最初の報告は1919年で、左脳卒中によってポルトガル語訛りになったチェコ人男性のケースでした1）。しかし、詳細な検討は行われておらず、病巣や言語所見についての学術的な検討を行った初期代表例としては、ノルウェーの神経学者であるMonrad-Krohnが1947年に発表した報告が挙げられます2）。同報告で紹介されてい

We will build a simple authentication module that is exposed via REST API while storing the data to PostgreSQL and Redis. We will use actix-web for handling the REST API part, sqlx for interacting with PostgreSQL, and redis-rs for interacting with Redis. We will see how the applicati

Part 1: Debugging Go in prod using eBPF | Pixie Labs Blog
This is the first in a series of posts describing how we can debug applications in production using eBPF, without recompilation/redeployment. This post describes how to use gobpf and uprobes to build a function argument tracer for Go applications. This technique is also extendable to other compiled languages such as C++, Rust, etc. The next sets of posts in this series will discuss using eBPF for
Rust is an appealing language for building user interfaces for a variety of reasons, especially the promise of delivering both performance and safety. However, finding a good architecture is challenging. Architectures that work well in other languages generally don’t adapt well to Rust, mostly because they rely on shared mutable state and that is not idiomatic Rust, to put it mildly. It is sometim
1 Introduction Compilers, assemblers and similar tools generate all the binary code that processors execute. It is no surprise then that these tools play a major role in security analysis and hardening of relevant binary code. Often the only practical way to protect all binaries with a particular security hardening method is to have the compiler do it. And, with software security becoming more and

Preparing for the Systems Design and Coding Interview
At Big Tech and high-growth startups, coding and systems design interviews are common - and fairly standard. A lot of people have asked me for preparation advice for these.

発表のポイント 銅酸化物高温超伝導体において、電荷が微少かつ均一に分布する乱れの無い極めて綺麗な結晶面を見出し、その電荷の振る舞いを解明した。 電荷分布に乱れのない綺麗な結晶面では、従来の常識に反して、モット絶縁体に注入される電荷が限りなく微少であっても長寿命の粒子が生成され、自由に動き回れることが分かった。 37年もの歴史を経て構築された銅酸化物高温超伝導体の電子相図は、乱れの影響を受けた結晶面特有のものである可能性が高い。それに変わるより本質的な電子相図を見出したことで、高温超伝導研究に新展開が期待される。 発表概要 東京大学物性研究所の黒川輝風大学院生（同大学大学院理学系研究科在籍（当時））、近藤猛准教授、および東京理科大学先進工学部電子システム工学科の磯野隼佑大学院生（当時）、常盤和靖教授の研究グループは、東京大学物性研究所の小濱芳允准教授、東京理科大学先進工学部物理工学科の遠山貴
Introduction Once you have deployed your machine learning model to production it rapidly becomes apparent that the work is not over. In many ways the journey is just beginning. How do you know if your models are behaving as you expect them to? What about next week/month/year when the customer (or fraudster) behavior changes and your training data is stale? These are complex challenges, compounded

という点についてオリビエ・ブランシャールとリカルド・ライスが議論している。具体的には、利上げでインフレを下げる際に失業率が上昇するのは副作用に過ぎず、失業率上昇という経路を通じてインフレが低下するわけではない、とリカルド・ライスがデビッド・ベックワースとの対談で述べ、その言葉をベックワースがツイッターで紹介したところ、ブランシャールが反応して以下のようにツイートしている。 Dear Ricardo, I am puzzled. For me, the increase in unemployment is causal, not a side effect, for inflation. Do you mean to say that, if we could avoid the side effect, we could decrease inflation without higher
Zoom’s Encryption Is “Not Suited for Secrets” and Has Surprising Links to China, Researchers Discover
Meetings on Zoom, the increasingly popular video conferencing service, are encrypted using an algorithm with serious, well-known weaknesses, and sometimes using keys issued by servers in China, even when meeting participants are all in North America, according to researchers at the University of Toronto. The researchers also found that Zoom protects video and audio content using a home-grown encry

Okay, obviously many SQL queries do start with SELECT (and actually this post is only about SELECT queries, not INSERTs or anything). But! Yesterday I was working on an explanation of window functions, and I found myself googling “can you filter based on the result of a window function”. As in – can you filter the result of a window function in a WHERE or HAVING or something? Eventually I conclude
How I developed a faster Ruby interpreter | Red Hat Developer
As a rule, RTL code contains fewer instructions than stack-based instructions, and as result spends less time in interpreter instruction dispatch code. But RTL sometimes spends more time in operand decoding. More importantly, RTL code results in less memory traffic, because local variables and stack values are addressed directly by RTL instructions. Therefore, stack pushes and pops of local variab

Cloud-native applications are dominating the market with their improved performance and high efficiency. While there are more resources to support cloud-native applications running as microservices, managing complex cloud architecture is still a challenge. The more microservices you run, the more tasks you will have to deal with in order to keep the cloud environment healthy and running smoothly.
