Hi everyone! 👋
Welcome to cron.weekly issue #154.
Any typos will be blamed on the cat, who insisted he co-write this issue.
Happy ☕️ time & enjoy!
News & general 🗞
This is a fun historic read on Markdown. I write it daily (and it’s the basis for this newsletter), it was interesting to read it dates back to even comics in the early 1900s.
An alternative exploit is one where some part of the command is hidden using CSS, but is still copied when you select it.
No more using
wine, a native 1 Password client for Linux is almost here!
A very detailed write-up of how Facebook is rolling out QUIC-HTTP/3 to all its users, describing the benefits & hurdles it encountered every step of the way.
The chicken/egg challenge of HTTP/3 (servers vs. clients) is slowly resolving itself, with Chrome enabling HTTP/3 by default and major internet platforms adding support as well.
The era of HTTP/3 is here!
First, the “Year 2038” problem everyone should be aware of:
Storing the time since 1970 in seconds will no longer fit in a signed 32-bit integer and thus wraparound
XFS has added some improvements that make it possible to store the seconds in a 64-bit integer instead, only causing a problem in 2486.
Tools & Projects 🛠
The latest 20.10 release of Ubuntu is available. Based on the 5.8 kernel, it’s quite an upgrade from the 20.04 LTS’s 5.4 kernel.
Smallstep SSH delivers an end-to-end workflow that marries modern identity providers with short-lived SSH certificates. Eliminate TOFU warnings and drop complex key approval & distribution processes. Extend single sign-on to SSH and make SSH keys ephemeral.
Give it a try, it’s free. Sponsored
View output of multiple processes, in parallel, in the console, with an interactive TUI - built on Python. Think of it as a lightweight Tmux.
OpenBSD 6.8 has been released. I’m too unfamiliar with OpenBSD to interpret the list of changes, but I do love that every 6 months the release is accompanied by a matching song.
Create custom dashboards for PostgreSQL and 400+ other technologies with Datadog’s unified monitoring platform. With drag-and-drop customization features, it only takes minutes to start monitoring PostgreSQL data and correlating it with metrics from the rest of your stack.
Start a free trial today, build one dashboard, and Datadog will send you a free t-shirt! Sponsored
While it’s only a minor release for
git, it does include an important (experimental) feature: SHA-256 support.
bat is like
cat on steroids: it supports syntax highlighting for a large number of programming and markup languages.
A modern alternative to
fail2ban, written in Go. Crowdsec is an open-source and lightweight software that allows you to detect peers with malevolent behaviors and block them from accessing your systems at various level (infrastructural, system, applicative). To achieve this, crowdsec reads logs from different sources (files, streams, …).
Guides & Tutorials 🎓
This is an older post if mine from 2016, which describes the key differences of HTTP/3 vs. its older versions. It’ll give you a good understanding of why HTTP/3 is needed and what it means to move from the TCP to the UDP transport layer.
Another look at the history of HTTP/3 and its road from HTTP/1.0 and onwards.
An engineer’s take on what it means to get to grips with the key concepts of MongoDB, when switching from a relational database environment.
It only occurred to me in this post, that if you’ve only ever learned the basics of SQL - without using joins or foreign keys - you probably wouldn’t notice the difference between relational databases and key/value stores like MongoDB. It’s just a dumber version of relational databases, and by doing so it can achieve greater throughput, easier sharding, etc.
This post contains lots of details & code examples for web developers on how to use Touch ID & Face ID to authenticate users on the web. If you’re serving primarily iOS users, this could be a very cool addition to your login flow.
This post answers the age-old question (in a funny way): is it possible to parse HTML using regular expressions?
After 13 years of git I just now discovered
git diff --color-moved— It detects and displays chunks that have moved, which is pretty common, in my experience. I find it really useful to be able to separate what has changed from what just moved around when reviewing some code.
I’m filing this on the “I’ll get to it once I retire”-pile. Super detailed, but does anyone really have the time to deep-dive into this? 😅
You will be joining a team that is responsible for ensuring that ECMWF and community-developed applications operate reliably and with good performance on our infrastructure. This will involve engaging with, advising, steering and supporting all functions involved in the lifecycle of application deployment and hosting. Your tech stack will include Ansible & Puppet and you’ll work cloud-native.
