I recently realized stdout is much faster than stderr for Rust. Here are my findings after diving deep into this rabbit hole. I have been using the terminal (i.e. command-line) for most of my day-to-day things for a while now. I was always fascinated by the fact that how quick and convenient the command-line might be and that's why I'm a proponent of using CLI (command-line) or TUI (terminal user
Posted on Monday, April 1, 2024. Updated Wednesday, April 3, 2024. Over a period of over two years, an attacker using the name “Jia Tan” worked as a diligent, effective contributor to the xz compression library, eventually being granted commit access and maintainership. Using that access, they installed a very subtle, carefully hidden backdoor into liblzma, a part of xz that also happens to be a d

12.6. B-Trees — CS3 Data Structures & Algorithms
12.6.1. B-Trees¶ This module presents the B-tree. B-trees are usually attributed to R. Bayer and E. McCreight who described the B-tree in a 1972 paper. By 1979, B-trees had replaced virtually all large-file access methods other than hashing. B-trees, or some variant of B-trees, are the standard file organization for applications requiring insertion, deletion, and key range searches. They are used
Over the last year or so, I have found myself on a journey to deeply understand how to run Rails applications backed by SQLite performantly and resiliently. In that time, I have learned various lessons that I want to share with you all now. I want to walk through where the problems lie, why they exist, and how to resolve them. And to start, we have to start with the reality that… Unfortunately, ru

Abigail Shrier’s Irreversible Damage: A Wealth of Irreversible Misinformation A critical, science-based analysis of Abigail Shrier’s book Irreversible Damage.

This article was adapted from my Rails World talk “Rails and the Ruby Garbage Collector: How to Speed Up Your Rails App”. Ruby’s garbage collector is designed to be adaptable, scaling from short Ruby scripts to running apps that serve millions of requests per second. While it’s designed to be adaptable, it may not work optimally for every use case. For this reason, Ruby’s garbage collector support

CloudFront Hosting Toolkitを使って静的Webサイト環境を作ってみた | DevelopersIO
手間をかけずにCloudFrontを使った静的Webサイトを作りたい こんにちは、のんピ(@non____97)です。 皆さんは手間をかけずにCloudFrontを使った静的Webサイトを作りたいなと思ったことはありますか? 私はあります。 過去にAWS CDKを使ってこの思いを実現したことがありますが、一からAWS CDKを作り込むのはなかなか大変でした。 そんな苦労はCloudFront Hosting Toolkitを使用すると少し解消されるかもしれません。 CloudFront Hosting ToolkitはCLIまたはAWS CDKでフロントエンドのホスティングとCI/CDパイプラインを用意するツールです。 今だとAmplifyを使えば良いのではないか? という声も聞こえてきますが、細かいカスタマイズを行いたい場合にCloudFront周りを直接操作したい場合があります。そうい
Russ Cox 28 August 2023 One of the key benefits of open-source software is that anyone can read the source code and inspect what it does. And yet most software, even open-source software, is downloaded in the form of compiled binaries, which are much more difficult to inspect. If an attacker wanted to run a supply chain attack on an open-source project, the least visible way would be to replace th
Database Migrations
Table of Contents I consider database migrations one of the most annoying problems to deal with during a software engineer’s life. Not only that, if it goes wrong, as it often does, people tend to develop anxiety related to any schema changes. So why is it so annoying? It looks simple at first glance but is deceptively tricky when you start thinking about it. My primary framework of choice is the

How Netflix Really Uses Java
Transcript Bakker: I'm going to talk about how Netflix is really using Java. You probably know that Netflix is really just about RxJava microservices, with Hystrix and Spring Cloud. Really, Chaos Monkeys are just running the show. I'm only half getting here because a few years ago, this was actually mostly true, maybe except the Chaos Monkeys. This stack was something that we were building on in t
The Big Cloud Exit FAQ
Just over a year ago, we announced our intention to leave the cloud. We then shared our complete $3.2 million cloud budget for 2022, and the fact that we were going to build our own tooling rather than pay for overpriced enterprise service contracts. The mission was set! A month later, we placed an order for $600,000 worth of Dell servers to carry our exit, and did the math to conservatively estim
38TB of data accidentally exposed by Microsoft AI researchers | Wiz Blog
Executive summary Microsoft’s AI research team, while publishing a bucket of open-source training data on GitHub, accidentally exposed 38 terabytes of additional private data — including a disk backup of two employees’ workstations. The backup includes secrets, private keys, passwords, and over 30,000 internal Microsoft Teams messages. The researchers shared their files using an Azure feature call

Terraform best practices for reliability at any scale
State file proliferation for fun and profitWhen first adopting Terraform there’s a natural attraction to having a single state file that covers your entire infrastructure. It’s simple. It’s expressive. It’s fast—at first. And it’s a terrible idea. At scale, many Terraform state files are better than one. But how do you draw the boundaries and decide which resources belong in which state files? Wha

■ 20世紀で最も並外れた知的信用詐欺 1960年にノーベル生理学・医学賞を受賞した生物学者、ピーター・メダワーはかつて「精神医学の被害者（Victims of Psychiatry）」と題した書評において、精神分析を「20世紀で最も並外れた知的信用詐欺（the most stupendous intellectual confidence trick of the 20th century）」と表現した。*1書評の対象は、アメリカの神経外科医I.S.クーパーの著作『The victim is always the same』で、変形性筋ジストニア（DMD）の若い患者が、それが神経筋疾患であるにもかかわらず精神疾患と誤診され、フロイト派の精神分析医によって行われる医学的にも倫理的にも不適当な「治療」を受けさせられる悲劇が描かれている。*2 精神医学における精神分析は前世紀半ばまでは隆盛を誇

Why Golang instead of Rust to develop the Krater desktop app | MoonGuard - Web Monitoring Tools
Hello! If you have been following our articles, you may remember reading that Krater was being developed with Rust using Tauri.

For the past 25 years, application software startups have had a singular focus: increasing company and employee (including developer) productivity. This looked like building software that increased productivity at the employee level, increased collaboration across employees and teams, and/or enabled better oversight and management at the leadership level. More often than not, this software has bee
I'm working on an application that needs the ability to schedule tasks. Many applications have a similar need, but requirements can vary greatly. Advanced cases might require persistence and distribution, typically depending on external systems (like a database or queue) to do much of the heavy lifting. My needs are simpler: I don't have a huge variety of tasks or a high number of them. Thread-Per

In CppCon 2022, Herb Sutter gave a talk titled Can C++ be 10x Simpler & Safer? where he described an alterntive syntax that compiles to C++ (which he calls CppFront or Cpp2) that could remove much of the existing issues with C++ - reduce complexity, increase safety, and more. If you haven't seen it yet, it's worth a watch! With recent events and discussions in the Haskell community, my mind went b

Data Security refers to practices employed in securing data from unauthorized tampering or corruption in an IT ecosystem. The entire digital world is run on data, and hence the statement, “data” is the new oil.” Data is in files, databases, accounts, and networks in forms like emails, passwords, texts, names, IDs, or electronic cash. We need to ensure the security of all these items from threat or

What happens when you push to GitHub? The answer, “My repository gets my changes” or maybe, “The refs on my remote get updated” is pretty much right—and that is a really important thing that happens, but there’s a whole lot more that goes on after that. To name a few examples: Pull requests are synchronized, meaning the diff and commits in your pull request reflect your newly pushed changes. Push
