Hello everyone, Asahi Lina here!✨ marcan asked me to write an article about the M1 GPU, so here we are~! It’s been a long road over the past few months and there’s a lot to cover, so I hope you enjoy it! What’s a GPU?You probably know what a GPU is, but do you know how they work under the hood? Let’s take a look! Almost all modern GPUs have the same main components: A bunch of shader cores, which
Paul Louth had a great development team at Meddbase, the healthcare software company he founded in 2005. But as the company grew, so did their bug count. That’s expected, up to a point. More code and more features mean more defects. But the defect rate was growing faster than Louth expected. “We were seeing more and more of the same types of bugs,” Louth says. “It was clear that there was an issue
At the start of this hectic year I have joined Micro, an open source microservices platform. The company was born out of a Go framework. We took the concepts of the framework - interfaces for service discovery, configuration and other pieces which can run on any implementation (from mdns locally to kubernetes) and provide a live platform version of it. It’s kind of like Netlify, but for the backen

This is a companion article to a talk about Docker+WebAssembly that we gave at "Docker Community All Hands 7, Winter Edition" on Dec 15th, 2022. Introduction Recently Docker announced support for WebAssembly in cooperation with WasmEdge. This article will explain what is WebAssembly, why it is relevant to the Docker ecosystem and provide some hands-on examples to try on. We assume you are familiar
Goodbye, Node.js Buffer
The Buffer type has been the cornerstone for binary data handling in Node.js since the beginning. However, these days we have Uint8Array, which is a native JavaScript type and works cross-platform. While Buffer is an instance of Uint8Array, it introduces numerous methods that are not available in other JavaScript environments. Consequently, code leveraging Buffer-specific methods needs polyfilling
Not long ago I decided to improve the loading times of my website. It already loads pretty fast, but I knew there was still room for improvement and one of them was CSS loading. I will walk you through the process and show you how you can improve your load times as well. Why loading time matters? Permalink to “Why loading time matters?” # Because Time is money. That proverb is especially true for
Browser-level image lazy loading for the web Stay organized with collections Save and categorize content based on your preferences. You can use the loading attribute to lazy-load images without the need to write custom lazy-loading code or use a separate JavaScript library. Here's a demo of the feature: Lazy-loaded images load as the user scrolls through the page. This page walks through the detai
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
Why we're leaving the cloud
Basecamp has had one foot in the cloud for well over a decade, and HEY has been running there exclusively since it was launched two years ago. We've run extensively in both Amazon's cloud and Google's cloud. We've run on bare virtual machines, we've run on Kubernetes. We've seen all the cloud has to offer, and tried most of it. It's finally time to conclude: Renting computers is (mostly) a bad dea

An in-depth guide to performance optimization with webpack - LogRocket Blog
These days, you have to use a module bundler like webpack to benefit from a development workflow that utilizes state-of-the-art performance optimization concepts. Module bundlers are built by brilliant people just to help you with these difficult tasks. In addition, I recommend using a starter kit or a modern boilerplate project with webpack configuration best practices already in place. Building
Sometimes our sites need a little sprinkling of content management. Not always. Not a lot. But a bit. The CMS market is thriving with affordable, approachable products, so we’re not short of options. Thankfully, it is a very different world to the one that used to force companies to splash out a ga-jillionty-one dollars (not an exact cost: I rounded to the nearest bazillion) for an all-singing, al
記事の中で映画、ゲーム、漫画などのネタバレが含まれているかもしれません。気になるかたは注意してお読みください。 #ネタバレ 映画の核心部分ですが、あまり語られてないので、解説してみます。 映画の中でアインシュタインが出てくるシーンは4箇所ありますが、この記事ではあくまで時系列に沿って3つに分けて記載します。 ▼1943年：核の連鎖反応についてニューメキシコ州のロスアラモスのオフィスが準備できるまでカリフォルニア州バークレーのオッペンハイマーの研究室で、マンハッタン計画は進んでいました。そこでテラーが核連鎖反応理論を提唱します。すぐに数学者たちで理論が正しいのか計算に取り組みますが、オッペンハイマーは別行動でニュージャージー州のプリンストン高等研究所のアインシュタインに会いに行きます。部外者だからこそ意見をもらう価値があると思ったからです。 OPPENHEIMER Neutron smash
Yesterday, I watched someone upload a video file to a chat app, ask a language model “Can you extract the first 5 s of the video?”, and then wait as the language model wrote a few lines of code and then actually executed that code, resulting in a downloadable video file. Oh, and writing and executing code is only one of the many new capabilities that can be seamlessly stitched together by the lang

Modern alternatives to BEM
Brainstorming a handful of new CSS organization acronyms August 26, 2022 When I first heard Nicole Sullivan talk about OOCSS, I thought “Oooh, smart.” When I read Jonathan Snook’s riff on that idea in SMACSS I thought “Oooh, smart.” When I heard Harry Roberts say “never use IDs in your CSS files” I said “Oooh, smart.” But when BEM and roboclasses came around… I didn’t have the same reaction. I nev
The selection of areas and methods is heavily influenced by my own interests; the selected topics are biased towards representation and transfer learning and towards natural language processing (NLP). I tried to cover the papers that I was aware of but likely missed many relevant ones—feel free to highlight them in the comments below. In all, I discuss the following highlights: Scaling up—and down

Python as a language is comparatively simple. And I believe, that you can learn quite a lot about Python and its features, just by learning what all of its builtins are, and what they do. And to back up that claim, I'll be doing just that. Just to be clear, this is not going to be a tutorial post. Covering such a vast amount of material in a single blog post, while starting from the beginning is p
23 Feb JavaScript performance beyond bundle size Posted February 23, 2021 by Nolan Lawson in performance, Web. 8 Comments There’s an old story about a drunk trying to find his keys in the streetlight. Why? Well, because that’s where it’s the brightest. It’s a funny story, but also relatable, because as humans we all tend to take the path of least resistance. I think we have the same problem in the

This release includes our fast linter and formatter; they require minimal configuration, come with beautiful and descriptive diagnostics, and have built-in support fo
It is often surprising how little is known about how databases operate at a surface level, considering they store almost all of the states in our applications. Yet, it's foundational to the overall success of most systems. So today, I will explain the two most important topics when working with RDBMSs indexes and transactions. So, without fully getting into the weeds on database-specific quirks, I
Hello! I wrote a comic last week called “life of a DNS query” that explains how DNS resolvers work. In this post, I want to explain how DNS resolvers work in a different way – with a short Go program that does the same thing described in the comic. The main function (resolve) is actually just 20 lines, including comments. I usually find it easier to understand things work when they come in the for
State machines orchestrate the work of AWS services, like Lambda functions. When one function ends, it triggers another function to begin. Although Max Duration is significantly different, Express workflow allows more scalability. Moreover, Express workflow pricing is constructed with more details since users will have to pay for the number of executions, including the duration and memory used for

Using GitHub Copilot in your IDE: Tips, tricks and best practices
AI has become an integral part of my workflow these days, and with the assistance of GitHub Copilot, I move a lot faster when I’m building a project. Having used AI tools to increase my productivity over the past year, I’ve realized that similar to learning how to use a new framework or library, we can enhance our efficiency with AI tools by learning how to best use them. In this blog post, I’ll s
Shifting to Zero Touch Production | Mercari Engineering
Author: Dylan Lau (@aidiruu), Platform DX Team Zero Touch Production (ZTP) is a concept where all changes made to production are done by automation, safe proxies or audited break-glass systems.

TL;DRWarpStream is an Apache Kafka® protocol compatible data streaming platform built directly on top of S3. It's delivered as a single, stateless Go binary so there are no local disks to manage, no brokers to rebalance, and no ZooKeeper to operate. WarpStream is 5-10x cheaper than Kafka in the cloud because data streams directly to and from S3 instead of using inter-zone networking, which can be

Dockerfiles are fundamental tools for developers working with Docker, serving as a blueprint for creating Docker images. These text documents contain all the commands a user could call on the command line to assemble an image. Understanding and effectively utilizing Dockerfiles can significantly streamline the development process, allowing for the automation of image creation and ensuring consiste
Hertzbleed Attack
Looking for the (unrelated) GPU.zip side channel? Check it out here! 📣 Update: Our follow-up paper expanding the scope of Hertzbleed has appeared in the IEEE Symposium on Security and Privacy 2023. See details below. Hertzbleed is a new family of side-channel attacks: frequency side channels. In the worst case, these attacks can allow an attacker to extract cryptographic keys from remote servers
Who murdered my lovely Prometheus container in Kubernetes cluster?

I’ve learned that the biggest difference between someone that has mastered a language, framework or tool and someone who hasn’t lies in the mental models they use. One person will have a clear and advanced one and the other will not. By having a good mental model you can intuitively understand complex problems and device solutions much faster than if you had to find a solution with a step-by-step
