I recently discovered an awesome tool called Coolify that calls itself an open-source Netlify or Heroku alternative that can be self-hosted. Gave it a whirl for my own personal projects and loved it, so I thought I’d share.
As the old saying goes, imitation is the sincerest form of flattery. In the software world, an open source alternative is the sincerest form of imitation. Well, Retool (a Changelog sponsor) can consider themselves flattered, because Openblocks sets out to do openly what they’ve been doing proprietarily. Here’s why:
It’s cumbersome to create a single app. You had to design user interfaces, write code in multiple languages and frameworks, and understand how all of that code works together.
Low-code/No-code platforms are fast to get started with but quickly become unmaintainable and inflexible. This creates more problems than it solves.
Retool-like solutions are great for their simplicity and flexibility, but they can also be limited in different ways compared to frameworks like React/Vue.
Openblocks wants to take a step forward. More specifically, Openblocks is
- An all-in-one IDE to create internal or customer-facing apps.
- A place to create, build and share building blocks of web applications.
- A domain-specific language that UI-configurable block is the first-class citizen.
Fathy Boundjadj new html2svg project is pretty cool. We’ve seen a lot of efforts to convert HTML to raster images like PNG and JPG, but SVG is a different (pixel-independent) story.
This end product took some engineering, and the linked post goes deep into all the steps Fathy had to take along the way. From taking the picture to rendering to SVG to supporting shadows and more.
Use it as a CLI, a server, a library, or inside a container 👌
It stores your shell history in context (what directory you ran the command in, whether it succeeded or failed, how long it took, etc). This is all stored locally and end-to-end encrypted for syncing to to all your other computers. All of this is easily queryable via the
hishtoryCLI. This means from your laptop, you can easily find that complex bash pipeline you wrote on your server, and see the context in which you ran it.
Podman Desktop installs, configures and keeps Podman up to date on your local environment. It provides a system tray, to check status and interact with your container engine without losing focus from other tasks. The desktop application provides a dashboard to interact with containers, images, pods and volumes but also configures your environment with your OCI registries and network settings. Podman Desktop also provides capabilities to connect and deploy pods to Kubernetes environments.
Katana can run in standard mode, which is like
$PATH and you’re off to the races!
According to this, 757 companies have laid off 104,791 employees thus far in 2022. Absolutely brutal.
Most internet speed testing tools focus on bandwidth, but latency and packet loss are major factors in the experience as well.
Bandwidth means, once things get going, how fast you can download. But “once things get going” can take a really long time. In fact, it can take longer than the whole download! This is especially true for simple web pages, or web pages made up of a bunch of tiny pieces, which is very common on today’s web… That’s where latency comes in.

This looks a lot like the early days of Postman. Built with Vue.js.
vdsql is a new plugin that allows VisiData to connect to databases and query them directly, using the database’s own query engine. It uses Ibis to generate SQL for many popular backends, including Postgres, DuckDB, Clickhouse, and more.
vdsql v0.2, released this past week, is already quite useful, and development continues to improve both vdsql and VisiData for bigger data!
ffmpeg is one of the foremost pillars of achievement in free software. It has touched the lives of every reader, whether they know it or not. If you’ve ever watched TV, or gone to a movie, or watched videos online, or listened to a podcast, odds are that ffmpeg was involved in making it possible. It is one of the most well-executed and important software projects of all time.
Yep. It also has one of the most epic man pages in the ’Verse.
This lets you do so many cool things, even joining across disparate services:
select aws.name aws_user_name, slack.id as slack_user_id, slack.display_name as slack_name from aws_iam_user as aws, slack_user as slack where aws.name = slack.email; +--------------------------+---------------+------------+ | aws_user_name | slack_user_id | slack_name | +--------------------------+---------------+------------+ | firstname.lastname@example.org | U2EMB8HLP | dwight | | email@example.com | U02HE4Z7E | jim | +--------------------------+---------------+------------+
Useful for compliance, security, ops, and cost management.
Diagrams are faster and compact way for knowledge transfer. It’s much easier to convey system architecture with a diagram compared to writing an essay on it.
Diagrams are especially useful in providing high level overview of software design. Following are the most-widely used diagrams by engineering teams…
The GNU Debugger is powerful, but it can also be inscrutable at times. Maybe this GUI will help?
This is a neat little CLI utility from Kelly Brazil that parses the output of common Unix system commands into JSON/YAML. We’re linking to the latest version (1.22.0) which adds new magic parsers for
/proc files. This handy glue-type tool gets one click neater every release!
Point Refurb at your Python code to see how
bad good it is. Here’s the author’s motivation:
I love doing code reviews: I like taking something and making it better, faster, more elegant, and so on. Lots of static analysis tools already exist, but none of them seem to be focused on making code more elegant, more readable, or more modern. That is where Refurb comes in.
The picture below explains it better than I can with words. 👇
WeightWatcher, created by Charles Martin, is an open source diagnostic tool for analyzing Neural Networks without training or even test data! Charles joins us in this episode to discuss the tool and how it fills certain gaps in current model evaluation workflows. Along the way, we discuss statistical methods from physics and a variety of practical ways to modify your training runs.
This tool calls itself the “best RSS search experience you can find” but really, are there other RSS search experiences out there? The results are a little underwhelming at the moment, but I’m sharing it because RSS and I’m sure it’ll get better with more eyes/feeds on it. 👀
Here’s Natasha Lekh from Apify describing the project:
This project really is a culmination of 4 years of work trying to make the best library for web scraping in production. Web scraping is a very dynamic environment and what works today might not work tomorrow, so we at Apify had to go through a lot of trial and error to figure out the most reliable and convenient ways of crawling the web and scraping data. We hope that we finally cracked it and that now many developers will enjoy working with our new library and it will make their scrapers more reliable and time to production faster.
maps.earth is a planet-scale installation of Headway, but you can easily set up your own server on a smaller scale for your own personal use by running just a few commands.
This is the first I’ve heard of Headway, but I love their mission:
The Headway Project was born out of a frustration with the need to send current and future location data to a corporation in order to figure out how we’re getting from A to B. Offline-only maps apps can be frustrating to use, and sometimes suffer from performance problems, poor data coverage, or other technical limitations.
Headway aims to remedy these issues by bundling industry-standard software into a web app that’s easy to set up for yourself or your friends. No need to send your location data to anyone you don’t trust, not even maps.earth.
As best I can tell, this provides simplified search across your infra, generates reports so you can easily audit resource usage, and lets you create/trigger jobs such as cleaning up unused resources and enforcing tag structures.
The search looks pretty powerful and you can pipe search results directly to jobs for quick processing:
search is(resource) and tags.owner==null | tag update owner "John Doe"
Pulls data from many sources. Built with Go. Demo video here.

I’m a CLI junkie, addicted to Vim motions, and never miss an opportunity to bring those two in to any part of my workflow. Naturally, I love to geek out about command line utilities and am always on the lookout for the next tool that can improve my productivity or just make CLI more fun to use. I can confidently say that Fzf is one of the handful of tools I’ve discovered over the years that has done both and has,thus, significantly improved the quality of my command line life.
