New toolkit! Gitlab Code Quality Report by Felipe Pinheiro Silva This library is mainly for CI purposes. From the RSL file generated in VI Analyzer it creates a JSON file which is compatible with the Gitlab Code Quality Widget which shows the code quality over time and in Merge Requests. Package is dependent on G-CLI.  Command line argument expects two arguments, the path for the RSL file, and the destination for the the json file. More information on how to setup in Gitlab is avaiable in the repository documentation. https://lnkd.in/gT7r6mbp Check it out: https://lnkd.in/gvyJ7Q5h

Five years ago, we started MuukTest with a question: Could we make "Great Software Testing and Automation" easier? My cofounder Renan Ugalde & I each have 20+ years of Software Development & QA experience. We've seen Bad Software Testing and Great Software Testing - way too much of the former, not enough of the latter: Bad Software Testing:  - Nonexistent professional testing team, expecting "developers to do all their own testing" (which 'works' until it doesn't) - Wild, non-disciplined, exploratory testing that doesn't help  - Testing that's treated as a second-class citizen in an engineering org, not as a partner - Reactive, under-resourced testing teams  - Testing with deficient coverage and no automation at all - Testing that's treated as the last step in an assembly line - Massive teams of testers, treated like a boiler room - Testing that slows engineering down I spent years of my life in Software QA and Testing roles like this… where I spent my Christmas holidays frantically, manually running regression tests across an entire application that *had* to be released yesterday. This is bad Software Testing. It is stressful for everyone and doesn't lead to good outcomes. Great Software Testing is:  - Proactive - A mix of (smart, disciplined, strategic) manual exploration and automation - Partner to engineering - Happens throughout the engineering cycle - Performed and coordinated by small teams of testing experts  - Employs amazing tools - Helps engineering move faster - Delivers insights, not more work Since 5 years ago, we have always believed that 'Great, Fast, Efficient Software Testing' will be made possible by AI. Bad testing happens because of bad ideas and bad tools, but with AI helping with a lot of the heavy lifting of test automation and maintenance, 'Great, Fast, Efficient Software Testing' is possible for more teams. Proud of our work in AI, making Great Software Testing possible for ANY software team. Great Software Testing means better software, faster development, happier customers, and better outcomes for all.

Test Driven Development & Developer Advocacy - Interview With Guilherme Ferreira You're not a real developer unless you do TDD. Gui Ferreira is a TDD expert -- but no, not even he would tell you this. In our chat together, we covered a lot of ground. It was great to sit down with a fellow Dometrain course author to go over: - His career journey - Developer advocacy - Test-driven development - And MUCH more! Huge thanks to Gui for the talk, and I'd love to do more in the future! 👇Check the comments for the video link!👇

🚨 Navigating the X Ban in Brazil: A Technical Perspective 🚨 (message me if you are interested in implementing software to continue your business.) As many of you may know, the recent ban of X (formerly Twitter) in Brazil has sparked significant challenges, particularly within the programming and tech community. This platform, which many of us rely on for real-time updates, networking, and knowledge sharing, is now inaccessible in a critical market. **Adaptability in the Face of Change** Adaptability is a necessity. While the sudden loss of access to X presents real difficulties, it also offers an opportunity for us to innovate and explore alternative solutions. 🔧 Technical Solutions to Stay Connected Alternative Platforms: Exploring other social platforms like [LinkedIn, Mastodon, etc.] to stay connected with the community and receive updates. Custom APIs and Aggregators: Implementing custom APIs to pull in data from various sources, ensuring that I don’t miss out on critical industry news and insights. This includes setting up RSS feeds and using Zapier to automate the aggregation of relevant content. Communication Tools: Using encrypted messaging services and VPNs to maintain communication with peers and clients who are also affected by this ban (while respecting the laws and being careful not to advise VPN usage for the Brazilians themselves as it is labeled as illegal). ⚙️ Problem-Solving in Action In this case, I'm ensuring that my productivity and ability to deliver quality work remain unaffected or the effects minimalized. This situation underscores the importance of being resourceful and having a toolkit of technical skills ready to deploy when traditional methods are no longer available. 🤝 Supporting the Community It's crucial that we stand together and share knowledge during times like these. I’d love to hear how others are navigating this disruption. What tools or strategies are you finding effective? Let’s keep the conversation going and find ways to overcome these challenges together. If you are interested in the technical workarounds, message me and we can go over your options as companies and individuals.

A few days ago, I started working on a prefetch implementation based on the recommendations from Unified Streaming’s documentation: https://lnkd.in/dKhQ6phN. Here’s the code: https://lnkd.in/dhwWeWdX (NGINX + Lua and a web server written in go for testing purposes) I haven’t tested it in production yet, but I would appreciate hearing from anyone with experience implementing something similar. If that’s you, could you please share your results? #videostreaming #livestreaming #videoengineering
