 Hello everyone. Bonjour. So I'm going to present the Lightning Talk alias telephone equals TOEFL drops down. So now what? This is me. I'm an architect from SIL. How do we meet open TOEFL? So at SIL, we build an open source software which is called VORUS. It helps to build application abstraction that works for multi-cloud. And we also use IAC technologies like telephone to for resource provisioning. So that allowing operation team to make a progressive transition to developer self-service. We have verified and integrated with open TOEFLs from the first stable release. And as the title of this talk suggests, the move into open TOEFL is pretty straightforward when you are familiar with telephone. So it is simple from the day one. Now what's the next move? A few months passed since the first release. So let me do a quick wrap up. I think open TOEFL is performing well thanks to the maintenance team. So the transparency is commendable. We have weekly updates. We have TSC summaries. So users can easily follow or know the progress and direction of the project. And we have hundreds of commits per month, which I would say is comparable to telephone. The documentation is also thorough. Including compatibility promises, migration guides and many other useful resources. If I were to ask why users should switch to open TOEFL, license must be one of the top factors. But can we expect more? Here we refers to both users and the community. So open TOEFL is actually a newly-bound project. But on the other hand, it also has a long, it inherits a long history from its predecessor, which is telephone. So I think from my opinion, I think we can learn from the past before planning for the future. So how do we do that? Let's look at some numbers. Maybe some phone numbers. All are from public sources. For example, we can collect all those telephone, GitHub issues, comments, events to help us provide some of the ideas. And we mainly focus on the enhancement and proposal issues and ignore those bugs because they are less relevant. So the analysis is also open source. So if you are interested in reviewing or reproducing, you can follow this linked report to take a look. Now let's start with some easy ones. So what's the oldest yet open issue in enhancement issue in telephone? Actually, that is open at 2016, which is about supporting the Docker provision. It actually might not be critical in our work throws by some issues there, my last for a long period before it has been resolved. So what is the highest number of the plus one reaction among those issues? The number is 1038. It's about using variables in telephone backhand configuration block. So I think in a nutshell, we want the configuration language more flexible. And we can see that this is an important topic in the following statistics. Now if we draw a line chart about the enhancement issues of telephone that is opened or closed per month, we can see this trend. So we can see that TEPRA is actually a successful project. As time goes, the community opening issues continues to grow. So we can see on the top right side, actually, this is the time when it changed the license. We can see the license change causes a little bit job of the number. But actually, it doesn't affect much of the overall trend. But if we aggregate those numbers by year, we can also see another trend. So this is the enhancement issues open and closed by year. We can see that the opened enhancement issues is decreasing. I think that might be what we call technology iteration curve as the technology as telephone itself goes mature. So if we try to tag all those enhancement issues by their domain or topic, we can also try to find in which area users may concern the most. So the first one is configuration language and syntax. So that we can, I think most users want to have more powerful expressive and flexible configuration languages. And the second one is the user interface and experience, which I think should be critical for any software adoption. And the third one is the state management, which I think is an important thing in the telephone system. The following is the provider framework and integration with external tools like CICD and then the model system and etc. So this is what users, telephone users or in the future maybe open tofu users would expect in the domains. Now, if we try to do some sentiment analysis on those open issues, we can see that there are some although not a large portion of them are marked as negative. So I think as the open tofu committee, we can check those negative issues to see if there is anything that yet to be resolved and if we can find some solution there. So these are my humble ideas to open discussions. And let me put one sentence to end. Open tofu is young, so let's help it grow. Okay, thank you. If you have any feedback, just second it and put your feedback. Okay, thanks.
