⏪⏪ Ever wished to rewind your debugging session? Imagine you're debugging a large form submission, Instead of redoing all its steps or workflow again in order just to debug, you can use the "𝗥𝗲𝗽𝗹𝗮𝘆 𝗫𝗛𝗥 𝗿𝗲𝗾𝘂𝗲𝘀𝘁" feature in Chrome DevTools. It is your time machine!🕐 This handy tool lets you resend captured XHR requests, perfect for testing API responses or debugging network interactions. Check out the official docs!

Dmitry Kostyuk is back with the next installment in the ConsolAS library development series! This time, he's diving into the nitty-gritty of building the table() method using test-driven development (TDD). As part of this Dmitry explains how he used Chrome's console.table() implementation as a basis for creating tests. But that's not all! Dmitry also gives us a peek into his project organization. He emphasizes the importance of a clean and efficient setup, with separate sections for tests, code, and settings. He promises to go into more detail about each aspect of the project in future posts, so stay tuned for more insights! #GoogleWorkspace #GoogleAppsScript Read more →

Thank you to Dev.to for featuring my thoughts on "Network Observability: Beyond Metrics and Logs" in their blog roundup this week. https://lnkd.in/gYHPq-6M

It's a nice comment from Glenn Jocher after he checked my solution for the GitHub issue to allow YOLO models or maybe any other computer vision model to save the result as an HLS stream based on RTSP and FFMPEG which allows any web client to work with the model with backend server. The exciting thing is that I published this solution maybe two years ago since yolo5, I was working on my graduation project, and it's still helpful for other developers, I can say this is one of my few times being on the other side of the open source community when I as developer contributes with other developers works which gives me some kind of motivation. #computer_vision #yolo #YOLO8 #Ultralytics

Fast-Music-Remover Demo Video is Out! Fast-Music-Remover, a lightweight tool I've recently open-sourced that efficiently removes noise and music from internet media, is growing steadily, with new contributors joining consistently! To showcase its current capabilities, we've now published a demo video(*) — check it out here or in the README on the public repository: https://lnkd.in/dDq4Seib As we prepare for live stream support, there are many technical challenges spanning the frontend, backend, and the core C++ MediaProcessor. If you're interested in contributing, take a look at the open issues: https://lnkd.in/dpqNu2cS You can easily try it out using Docker, and we're also close to releasing a Windows binary — stay tuned! Thanks for taking a look and helping spread the word!

This ain't your normal debugger! Replay.io is a time-traveling debugger: you can jump in and interact with your app from any moment during the recording! In this video (part 1) Mark Erikson gives us a primer on what Replay is and how you can benefit from using it.

🌟 Had a funny tech moment today! Usually, I open Developer Tools on Chrome using these tricks: * Pressing Keys: Just hit Ctrl + Shift + I (or Cmd + Option + I on a Mac), and boom! You're in. * Menu Clicking: Or, click the three dots in the top corner, then "More Tools," and "Developer Tools." * Right-Clicking: Feeling fancy? Right-click anywhere on a webpage and pick "Inspect." But guess what? Just today, in a moment of distraction, I accidentally hit the F12 key... and bam! Developer Tools popped up. Talk about a happy accident! Fun fact: The F12 key actually opens and closes Developer Mode. Who knew, right? Ever had a tech moment like this? Share your stories below! Let's celebrate those accidental discoveries that make our tech journeys even more fun. 🚀💻 Feel free to share your favorite shortcut commands too! Let's learn together. 🔗 #TechHumor #DeveloperTools #HappyAccident #TechJourney #Discoveries #ShortcutCommands #LearningTogether

I just made an http server that when pinged, uses gstreamer to grab the main video device on the device, and begin recording until another request stops it. (In rust!) Just a few hours for something incredibly useful. What's exceptionally cursed is, this doesn't light up the camera light on my mac. Wow. That's spooky lmao 🙃 I think they thought this take home would take a bit longer. I did take a few take-homey shortcuts, but I do have limited time this week; They said that that was acceptable int he email, so I'm hoping they don't mind. Very interesting problem however. 👀 Also, the gstreamer suite for rust is exceptionally poorly documented unfortunately and I may do my part to help with fixing that when I find the time. It was very fun to do this project, but some of their primitives flat out don't seem to work as expected. I'm not exactly a rock brained dummy so that was a bit shocking. I looked to the internet and it looked like older versions had completely different formatting All of these code changes are utterly breaking. e.g. letavfvideosrc = gst::ElementFactory::make("avfvideosrc", Some("source")).unwrap(); has seemingly become letavfvideosrc = gst::ElementFactory::make("avfvideosrc"); According to the compiler. Adjusting versions even a few versions seems to fully break compiling code. Maybe Gstreamer needs some help with maintaining it? 🤔 You don't need to be a genius to see you can be helpful. Just sharing how to use this arcane stuff would be a million degrees helpful for somebody somewhere I guarantee it. That may be my next pet project after I finish bootstrapping my new personal project next week. This is all so wild to me lol, just shows how much rust has changed in just a few short years. #softwareEngineering #latenightcoding #LateNights #nightowl #lovecode #engineering #engineeringleader #topvoice #rustsoftwareengineering #rust
