jQuery 4.0.0 has been in the works for a long time, but it is now ready for a beta release! There’s a lot to cover, and the team is excited to see it released. We’ve got bug fixes, performance improvements, and some breaking changes. We removed support for IE<11 after all! Still, we expect disruption to be minimal. Many of the breaking changes are ones the team has wanted to make for years, but co
Introducing workerd: the Open Source Workers runtime09/27/2022 Today I'm proud to introduce the first beta release of workerd, the JavaScript/Wasm runtime based on the same code that powers Cloudflare Workers. workerd is Open Source under the Apache License version 2.0. workerd shares most of its code with the runtime that powers Cloudflare Workers, but with some changes designed to make it more p

“Build once, deploy anywhere” is really nice on the paper but if you want to use ARM targets to reduce your bill, such as Raspberry Pis and AWS A1 instances, or even keep using your old i386 servers, deploying everywhere can become a tricky problem as you need to build your software for these platforms. To fix this problem, Docker introduced the principle of multi-arch builds and we’ll see how to
jQuery 3.5.0 has been released! As usual, the release is available on our cdn and the npm package manager. Other third party CDNs will probably have it soon as well, but remember that we don’t control their release schedules and they will need some time. We hope you’re staying healthy and safe while so many of us are stuck at home. With a virus ravaging the planet, we realize that jQuery may not b

Introduction 11 May 2021 — This website presents FragAttacks (fragmentation and aggregation attacks) which is a collection of new security vulnerabilities that affect Wi-Fi devices. An adversary that is within range of a victim's Wi-Fi network can abuse these vulnerabilities to steal user information or attack devices. Three of the discovered vulnerabilities are design flaws in the Wi-Fi standard

Introduction to Go 1.21 The latest Go release, version 1.21, arrives six months after Go 1.20. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility; in fact, Go 1.21 improves upon that promise. We expect almost all Go programs to continue to compile and run as before. Go 1.21 introduces a small ch

Passkeys を完全に理解するために Rails で実装してみた with Remix - STORES Product Blog
この記事は STORES Advent Calendar 2023 22日目の記事です。 こんにちは STORES 予約開発チームでエンジニアリングマネージャーをしています Natsume です。 昨今 Passkeys が各サービスで導入されており、勢いを感じています。 個人では 1Password のパスワードマネージャーを使っており、1Password が Passkeys 対応してから試しています。 Passkeys でのログインは ID/PW/OTP の autofill などに比べて 1step 省略される程度ですが、ログイン体験が良いと思っており、導入されていたらどんどん切り替えています。 ほどんどのサービスでは ID/PW との併用となっているケースが多く、セキュリティ面でのメリットを享受できるのはまだ先になりそうです。 個人的に Passkeys の実際の挙動や導入する時
Raccoon Attack
Paper Q&A Raccoon is a timing vulnerability in the TLS specification that affects HTTPS and other services that rely on SSL and TLS. These protocols allow everyone on the Internet to browse the web, use email, shop online, and send instant messages without third-parties being able to read the communication. Raccoon allows attackers under certain conditions to break the encryption and read sensitiv

There is an area of Python that many developers have problems with. This is an area that has seen many different solutions pop up over the years, with many different opinions, wars, and attempts to solve it. Many have complained about the packaging ecosystem and tools making their lives harder. Many beginners are confused about virtual environments. But does it have to be this way? Are the current
I first learned Kubernetes ("k8s" for short) in 2018, when my manager sat me down and said "Cloudflare is migrating to Kubernetes, and you're handling our team's migration." This was slightly terrifying to me, because I was a good programmer and a mediocre engineer. I knew how to write code, but I didn't know how to deploy it, or monitor it in production. My computer science degree had taught me a
Tier 4 Support § Support for these targets is entirely experimental. If this target is provided by LLVM, LLVM may have the target as an experimental target, which means that you need to use Zig-provided binaries for the target to be available, or build LLVM from source with special configure flags. zig targets will display the target if it is available. This target may be considered deprecated by

This vulnerability exploits a design flaw in the WiFi standard, allowing attackers to trick WiFi clients on any operating system into connecting to a untrusted network. A new vulnerability arising from a design flaw in the WiFi standard allows attackers to trick victims into connecting to less secure networks and intercept their traffic. Additionally, the attack can exploit the auto-disconnect fea

I ended up reading about CBOR and MessagePack. Both of these are binary formats for a JSON-like data model. Both of them are "schemaless", meaning you can decode them without knowing the structure.

Story: Redis and its creator antirez | Brachiosoft Blog
This article is translated from the original Chinese edition. In the world of databases, Redis stands out as unique. Instead of the usual tables or documents that are the central focus of most databases, with Redis, you interact directly with low-level data structures such as linked lists and hash tables. This is all thanks to the innovative design of Redis creator Salvatore Sanfilippo, known onli

And while pranks on April Fools’ seem less and less fun1, obvious jokes and

In this report, we look at the data generated by the O’Reilly online learning platform to discern trends in the technology industry—trends technology leaders need to follow. But what are “trends”? All too often, trends degenerate into horse races over languages and platforms. Look at all the angst heating up social media when TIOBE or RedMonk releases their reports on language rankings.

Building a large-scale distributed storage system based on Raft
Guest post by Edward Huang, Co-founder & CTO of PingCAP In recent years, building a large-scale distributed storage system has become a hot topic. Distributed consensus algorithms like Paxos and Raft are the focus of many technical articles. But those articles tend to be introductory, describing the basics of the algorithm and log replication. They seldom cover how to build a large-scale distribut
SELECT code_execution FROM * USING SQLite; - Check Point Research

However, from a security perspective, it has only been examined through the lens of WebSQL and browser exploitation. We believe that this is just the tip of the iceberg. In our long term research, we experimented with the exploitation of memory corruption
