Memzoom
Memzoom lets you view/monitor the raw memory of processes/files in your UTF-8 terminal. Memzoom is like the less command except designed for binary data with live updates. It represents non-ASCII characters using IBM Code Page 437 as a base-256 binary alphabet. It implements zooming via CTRL+MOUSEWHEEL which uses an image scaling algorithm (better than Lanczos!) that enables you to monitor large a

Catalog of Patterns of Distributed Systems
Distributed systems provide a particular challenge to program. They often require us to have multiple copies of data, which need to keep synchronized. Yet we cannot rely on processing nodes working reliably, and network delays can easily lead to inconsistencies. Despite this, many organizations rely on a range of core distributed software handling data storage, messaging, system management, and co
Remix vs Next.js
Easily the biggest question we get asked is something like: How is Remix different from Next.js? It appears we have to answer this question! We'd like to address it directly and without drama. If you're a fan of Remix and want to start tweeting smug reactions to this article, we kindly ask that you drop the smugness before hitting the tweet button 🤗. A rising tide lifts all boats. We've been frie
Kernel Queue: The Complete Guide On The Most Essential Technology For High-Performance I/O
Kernel Queue: The Complete Guide On The Most Essential Technology For High-Performance I/O When talking about high-performance software we probably think of server software (such as nginx) which processes millions requests from thousands clients in parallel. Surely, what makes server software work so fast is high-end CPU running with huge amount of memory and a very fast network link. But even the

Do You Really Need Redis? How to Get Away with Just PostgreSQL
Do You Really Need Redis? How to Get Away with Just PostgreSQL There’s a tried-and-true architecture that I’ve seen many times for supporting your web services and applications: PostgreSQL for data storage Redis for coordinating background job queues (and some limited atomic operations) Redis is fantastic, but what if I told you that its most common use cases for this stack could actually be achie
GitHub Next | Flat Data
Flat explores how to make it easy to work with data in git and GitHub. It builds on the “git scraping” approach pioneered by Simon Willison to offer a simple pattern for bringing working datasets into your repositories and versioning them, because developing against local datasets is faster and easier than working with data over the wire.
Clickhouse as an alternative to ElasticSearch and MySQL, for log storage and analysis, in 2021
In 2018, I've written an article about Clickhouse, this piece of content is still pretty popular across the internet, and even was translated a few times. More than two years have passed since, and the pace of Clickhouse development is not slowing down: 800 merged PRs just during last month! This didn't blow your mind? Check out the full changelog, for example for 2020: https://clickhouse.tech/doc
Introducing Private Click Measurement, PCM
This blog post covers a new feature called Private Click Measurement, or PCM, for measuring ad clicks across websites and from iOS apps to websites. It is part of iOS and iPadOS 14.5 betas. Motivation and Goals Classic ad attribution on the web is done with cookies carrying user or device IDs. Such attribution constitutes cross-site tracking which WebKit is committed to preventing. Websites should
Why use GraphQL? | Apollo GraphQL Blog
Before there was GraphQL, there was REST. In recent years, REST has become the dominant API style for building backend web services. With REST, you could signal the type of request we want to make (ex: GET, POST, PUT, or DELETE) and the resource we’d like to fetch or interact with (ex: /api/pets/1) using an HTTP method and a URL. It’s a great approach (and one we initially used at StockX for sever
JavaScript's Memory Management Explained | Felix Gerschau
javascriptJavaScript's Memory Management ExplainedEven though the JavaScript engine manages memory for us, it's good to know what happens under the hood. Read in Chinese or Korean Most of the time, you can probably get by fine not knowing anything about memory management as a JavaScript developer. Afterall, the JavaScript engine handles this for you. At one point or another, though, you'll encount
「RDB生みの親」の提言から50年、データの泥沼から出られない日本企業
「将来、大規模なデータバンクにおいては、データがマシン内でどのように編成されているか（内部表現）について、ユーザーが意識しなくて済むようにしなければならない」 これはリレーショナルデータベース（RDB）の生みの親、エドガー・フランク・コッド博士が1970年に発表した、いわゆる「コッド論文」の冒頭にある言葉である。原文は次の通りで筆者が訳した。 “Future users of large data banks must be protected from having to know how the data is organized in the machine（the internal representation）.” コッド博士の提言を実現するには、ビジネスの現場を担うユーザーが理解でき、場合によっては自ら記述できるデータの定義と、定義に沿ったデータをつくり出し、処理する情報システ

Deep Dive: NewSQL Databases
Overview One of my colleagues, @margo_hdb, recently posted a great article Database Architectures & Use Cases - Explained here on dev.to. In response a user asked for a deeper dive on NewSQL databases, so I thought I would put one together. The term NewSQL was coined in 2011 by 451 Group analyst Matthew Aslett. Wikipedia defines the term below: “ NewSQL is a class of relational database management
Moving from TypeScript to Rust / WebAssembly | nicolodavis.com
I recently decided to switch the engine of Boardgame Lab from TypeScript to Rust. The application itself is an SPA written in Svelte. I only switched the logic that updates the game state to Rust. Here is a summary of my experience with the transition: Isomorphic ArchitectureOne of the advantages of using JavaScript or TypeScript is that you can run the same code on both client and server.
