Data build tool (dbt) is a popular open-source data transformation tool that enables analytics engineers to transform data in their warehouses through SQL statements. The TiDB community recently released the dbt-tidb adapter to make TiDB a distributed SQL database to work with dbt. Through the dbt-tidb plug-in, analytics engineers working with TiDB can directly create forms and match data through SQL without having to think about the process of creating tables or views. They can also use Jinja, a dbt template language for writing SQL, test, package management, and other functions, which greatly improves efficiency.
In this tutorial, I will show you how to use dbt with TiDB. Before you try any of the steps below, make sure the following items are installed:
We will learn about the following streaming protocols in order:
RTMP
RTSP
WebRTC
HLS
SRT
CMAF
RTMP (Real-Time Messaging Protocol)
RTMP streaming protocol, a TCP-based technology, was developed by Macromedia for streaming audio, video, and data over the Internet between a Flash player and a server. Macromedia was purchased by its rival Adobe on December 3, 2005, but with the phasing out of Flash in 2020, its use has become less to do with viewer-facing delivery of content and more for ingesting live streams into a platform through RTMP-enabled encoders.
As the website-building experience is something we improve on daily, it’s no surprise that a tool like WP Maintenance exists. If you’re not sure what we’re talking about, it’s a WordPress plugin that gives you...
WordCamp Europe 2022 concluded last weekend in Porto, Portugal. The event sold 2,746 tickets and had 2,304 people attend. It kicked off with a record-setting Contributor Day that coordinated the efforts of 800 participants giving back to WordPress and its related projects.
WCEU featured 70 speakers across 26 sessions and 18 workshops, made possible by the efforts of 65 sponsors, 91 organizers, and 164 volunteers.
Attendees and organizers were thrilled to be back together in person after two years of not hosting the event due to the COVID-19 pandemic. Remkus de Vries, one of the founders of WCEU, joined our recent WP Jukebox podcast and commented on the importance of being back in person with fellow WordPress enthusiasts. He characterized WordCamps as the “glue” that keeps the community together.
“I think the glue part is way more important than people thought that it was,” de Vries said. “I think you can say the same thing for what we’re seeing here. Yes, you can be connected. You can have great relationships online and everything, but the real deal is in real life. That’s where you make the actual connections.
“You have things you say that you then in real life have time to correct if that wasn’t the intent that you actually had. All of these little things make up what that glue actually consists of, so not having that for two years creates a like a vacuum of things that are not seen, not communicated, not spoken about, not processed.
“There have been companies started from WordCamps. There have been mergers started. There have been friends made there have been marriages come from WordCamps. Everything happens when you’re together.”
In 2023, the project that is democratizing publishing will be hosting its European conference in the birthplace of democracy, Athens, Greece. The date is set for June 8-10, and the call for organizers has already been published. Check out the intro video below for a taste of what’s to come next year.
When you’re working in a group, you need to know how to coordinate. Coordination requires a shared understanding of how everyone will work together. Most human groups define Roles. Roles help clarify boundaries and expectations for people working together.
For example, in sports, these roles are called Positions. To play well, you need all the positions to understand how to work with each other. And you need everyone to focus on their position. It would be ridiculous in football (aka soccer) to have everyone try and be the goalkeeper.
While it might seem like instructional video is a modern invention, it can trace its way to the beginning of moving images. However, there hasn’t been a straightforward way to record your screen on Windows, Mac, or Linux until this last decade. Given the amount of time we all use computers, you’ll likely need a solution for this purpose on your machine on an occasional basis at the very least.
When you think of a billion-dollar tech company, you probably imagine rooms full of monitors with dashboards and non-stop data streams.
Well, after talking to Hippo - a certified unicorn and newly minted giant in the insurance industry - we realized this couldn’t be further from the truth.

I got to speak to Jon Kantner! Jon is an incredibly prolific creator, and I believe has the most appearances in the CodePen Spark of any creator. Like so many other creators I’ve talked to Jon also shares what he knows in a variety of ways, like writing (see his personal site, or articles he wrote when I ran CSS-Tricks). We got to chat about some of his iconic Pens, his work, and some past fascinations like Tweet-sized code experiments. Follow him on Twitter here.

Ah, writing chats. So simple yet so complex. Yes, writing chats — as in coding them, not chatting (though that might prove to be problematic too, but that’s a whole different problem). If you’re looking for a step-by-step tutorial on implementing the backend for a basic multichannel chat, read on.
So let’s dive into the technicalities. To give you some more details, the service will be implemented as a mix of a simple REST API and a Web Socket app. To make this more interesting, I decided to use Akka-related libraries and typed actors in as many numbers as possible.
