Run your own CI pipeline with GStreamer's new monorepo

Recently, the GStreamer project merged all its git repositories into a single, unified repository, often called monorepo. You can read more about this change here. One benefit is it greatly simplifies maintaining custom, project specific, GStreamer patches. Previously, projects that needed to develop, or backport, some patches had to go through multiple steps to complete the task. Projects had to fork various git repositories (e.g. gst-plugins-good, gst-plugins-bad, etc), each repository would then have a new branch with the extra commits, and often, gst-build was used to pull all of these repositories together (and gst-build itself had to be patched beforehand to download forked repositories). Thankfully, all that will be a thing of the past.

GitOps: Best practices for the real world

There is a common misunderstanding about how GitOps should be applied in real-world environments. Developers equate Infrastructure as Code (IaC) with GitOps in concept or believe that GitOps can only work with container-based applications — which is not true. In this blog, you will learn what GitOps is and how to apply its principles to real-world development and operations.

5 Open Source tools for Documenting your React Component - DEV Community

In this article, we will take an overview of 5 tools whose purpose is to help us in documenting our React Components with bare minimum efforts thus, which have made documenting our React Components a piece of cake.

Meson version bumped to 0.59.2

Meson is a source package build system. EasyOS has version 0.53.0, however, I wanted to compile the latest 'pipewire' package and it requires meson version 0.54.0 or later. So, have recompiled meson in OpenEmbedded, now version 0.59.2.

Reviving Net::Pcap

... in which I look at how existing patches floating on the internet can be integrated into Net::Pcap to make it compile again. Net::Pcap is dear to me, as I have a module implementing an HTTP sniffer using its network capture. So I like it when the module compiles without too much manual work.

Smart Flower Pot Build Is All About That Base | Hackaday

This attractive beginner build is a Python-powered project that runs on a PyPortal Titano and has a speaker that anthropomorphizes the thing so it can berate you politely ask for water in English. But the real magic of this build is in the enclosure itself.

Best Plugins for PyCharm

Plugins are add-ons that enable you to optimize your applications. For instance, if you want to live-stream a soccer match on a website, you may need to install a plugin because your browser doesn’t come with preinstalled streaming tools. You might want to think of plugins as an integral part of your computing and web browsing, making sure each activity you do is running smoothly, even if it is just about viewing a document or surfing a blog.

Duplicate records differing only in unique identifiers

There's a big data table with lots of fields and lots of records. Each record has one or more unique identifier field entries. How to check for records that are exactly the same, apart from those unique identifiers? I've been tinkering with this problem for years, and you can read my last, fairly clumsy effort in this BASHing data blog post from 2020. Here I present a much-improved solution, which has also gone into A Data Cleaner's Cookbook as an update. In 2020, the fastest and most reliable method I used to extract these partial duplicates was with an AWK array and two passes through the table. In the first pass, an array "a" is built with the non-unique-identifier field entries as index string and the tally of each different entry as the value string. In the second pass through the table, AWK looks for records where the value string for the same index string is greater than one, and by default prints the record.

Excellent Free Tutorials to Learn Bash - LinuxLinks

Bash (acronym for the ‘Bourne-Again-SHell’) is the GNU Project’s shell and programming language. It’s an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). Bash has become a de facto standard for shell scripting. It runs on almost all versions of Unix and a few other operating systems including Windows platforms. A Unix shell is both a command interpreter and a programming language. As a command interpreter, the shell provides the user interface to various utilities. The programming language features of Bash allow these utilities to be combined. Files containing commands can be developed, and become commands themselves. A shell script is therefore a quick way of prototyping a complex application. Shell scripting follows the classic Unix philosophy of breaking complex projects into simpler subtasks, of chaining together components and utilities. Like all Unix shells, Bash supports filename globbing (wildcard matching), piping, here documents, command substitution, variables and control structures for condition-testing and iteration. The keywords, syntax and other basic features of the language were all copied from sh. Here’s our recommended free tutorials to learn Bash.

Classic 80s Text-To-Speech On Classic 80s Hardware | Hackaday

Those of us who were around in the late 70s and into the 80s might remember the Speak & Spell, a children’s toy with a remarkable text-to-speech synthesizer. While it sounds dated by today’s standards, it was revolutionary for the time and was riding a wave of text-to-speech functionality that was starting to arrive to various computers of the era. While a lot of them used dedicated hardware to perform the speech synthesis, some computers were powerful enough to do this in software, but others were not quite able. The VIC-20 was one of the latter, but thanks to an ESP8266 it has been retroactively given this function. This project comes to us from [Jan Derogee], a connoisseur of this retrocomputer, and builds on the work by [Earle F. Philhower] who ported the retro speech synthesis software known as SAM from assembly to C which made it possible to run on the ESP8266. Audio playback is handled on the I2S port, but some work needed to be done to get this to work smoothly since this port also handles the communication with the VIC-20. Once this was sorted out, a patch was made to be able to hear the computer’s audio as well as the speech synthesizer’s. Finally, a serial command interface was designed by [Jan] which allows for control of the module.

When leading openly means leading with vulnerability

In the second part of my interview with Sam Knuth, a fellow Open Organization Ambassador, we discussed how leaders can identify areas for coaching open management practices within their organization to ensure the managers they lead are letting open values guide their work teams and associates. It takes emotional intelligence—and effort. To wrap our time together, Sam and I discussed understanding and showing vulnerability with others in the workplace. Sam has authored articles on this important topic for Opensource.com, and his stories about life as an open leader showcase a passion for those (and other) open values. In this interview, we discuss the benefits of leaders showing vulnerability.

Intel hopes to burn newly open-sourced AI debug tech into chips [Ed: Shoddy openwashing by Intel with "hey hi" thrown into the mix for hype or good measure]

Intel Labs has big plans for a software tool called ControlFlag that uses artificial intelligence to scan through code and pick out errors. One of those goals, perhaps way out in the future, is to bake it into chip packages as a last line of defense against faulty code. This could make the information flow on communications channels safer and efficient.

SuperSlicer Reviewed: Another 3DP Slicer? | Hackaday

When you think of slicers for FDM 3D printing — especially free slicers — you probably think of Cura, Slic3r, or PrusaSlicer. There are fans of MatterControl and many people pay for Simplify3D. However, there are quite a few other slicers out there including the one [TeachingTech] has switched to: SuperSlicer. You can see his video review, below. Of course, just as PrusaSlicer is a fork of Slic3r, SuperSlicer is a fork of the Prusa software. According to the project’s home page, the slicer does everything Prusa does but adds custom calibration tests, ironing, better thin wall support, and several other features related to infill and top surfaces. The software runs on Windows, Linux, or Mac.

Lead Cloud-Native Security Analytics Engineer Shares Top Tips for Securing the Enterprise

Cloud and container adoption is on the rise, as organizations are increasingly recognizing the potential for rapid growth and evolution that cloud-based infrastructure offers. That being said, along with these advantages comes significant security challenges. The modern cloud-native attack surface is complex and difficult to secure with many “moving pieces” including endpoints, servers, containers and cloud providers. This makes integrating Threat Intelligence data gathered from all of these surfaces and evaluating potential security and compliance risks and active threats no easy task. Not only is risk harder to identify and evaluate in cloud and container environments, security vulnerabilities, malware and other threats that are also easier to inadvertently inherit from common layers and shared components frequently used in container builds.

Surf Sensor Adds Depth To Finding The Ultimate Wave

o say that the ocean is a dynamic environment would be a gross understatement, especially when coastlines are involved. Waves crash, tides go in and out, and countless variables make even the usual conditions a guessing game. When [foobarbecue] goes surfing, he tries to take into account all of these things. The best waves at his local beach are directly over an ever-moving sand bar, and their dynamics are affected by depth, another constant variable. [foobarbecue]’s brilliant solution to understanding current conditions? Build a depth finder directly into his surf board! At the heart of the “surfsonar” is the Ping Sonar Echosounder, a sonar transducer designed for AUV’s and ROV’s. [foobarbecue] embedded the transducer directly into the board. Data is fed to a Raspberry Pi 4b, which displays depth and confidence (a percentage of how sure it is of the measurement) on a 2.13 inch e-Paper Display Hat.
