Editor's Notes
- Thank you for joining us and congratulations to the OSCC team for another great conference! It’s a privilege and a pleasure to participate. This panel will provide updates and discuss several ongoing projects: Avatar-focused viewers for OpenSimulator New Voice Applications for OpenSimulator And Docker-based OpenSimulator Grid Deployment
- Let’s get started by talking about the current development state of SceneGate.
- Project SceneGate encompasses both SceneGate and future viewer efforts for OpenSimulator dedicated viewers that are avatar-focused. The COVID crisis had an impact in 2020 on the development team globally slowing progress. We also have multiple requests for new capabilities and features regarding the armature and the user interface. These will need to go through team review next year after IMA Whitepaper submission. This process is defined here https://bitbucket.org/imadevelopmentteam/scenegate-viewer/wiki/Policies%20and%20Procedures:/Request%20a%20Feature We plan to move the repository to a Gitea server we will host to reduce costs and ease administration in the future. Work is underway to support three user operating systems and our autobuild has been updated to support using VS 2019 Community Edition. The future viewer project that Frank will talk about will help provide architecture documentation for developers. Following up from our security testing last year and whitepaper review, work has begun to improve viewer security. Before we talk about security, let’s take a look at the current roadmap.
- We did have to slip our milestone on the project roadmap https://bitbucket.org/imadevelopmentteam/scenegate-viewer/wiki/Development%20Resources:/Project%20Roadmap But we very much appreciate the user feedback and have included some bug fixes for the next beta release. Integration with EchoVoice that Seth will discuss is planned. We also want to expand our team to spinoff the DreamGate viewer project. DreamGate will likely be a fork of Firestorm so that creators with accessibility needs have features available that we added to SceneGate. If you are interested in joining the development team to work on DreamGate contact me. I am happy to alternatively discuss a joint effort with the Firestorm OpenSimulator development team. Longer term, we plan to add advanced tools to SceneGate so advanced users with accessibility needs will be able to use either viewer. Currently, Vivox does not have group IM (conferencing) in OpenSimulator but this is one of the EchoVoice roadmap items. We may need to make some changes to SceneGate code and Helios (our OpenSimulator fork) to support that. If needed, our team is happy to provide inputs for OS Devs or other viewer devs to include in their development framework. We also want to look at disabling the analyze button for mesh uploads to eliminate user issues. Because users often use the map to find other users, we want to investigate removing NPCs from the maps and radar. Chromium related updates for media streaming are needed. Finally, work will continue to decouple menu options tied to SL and address bugs. Let’s look at the current issue tracker.
- We really appreciate participation from the community on issue tracking! Two issues are resolved, four open issues are to be addressed in the next beta release, one issue needs team review after whitepaper submission, and three issues related to Linux users need to be investigated. You can download the viewer here http://downloads.infinitemetaverse.org/index.php/downloads Our issue tracker is currently located here https://bitbucket.org/imadevelopmentteam/scenegate-viewer/issues
- In 2019, Natacha did a lot of source code security investigation regarding third party libraries. The chart on the left shows vulnerabilities for all three major operating systems. As you can see, third party libraries used by Mac showed the greatest vulnerability. Third party libraries are often used to accelerate development but that comes with a price. Often not kept up to date, these libraries are one of the most insecure parts of an application. Hackers began to move away from servers and operating systems in 2016 towards applications. 90 percent of all applications require download of these components making exploits attractive to hackers. The more third party libraries used the greater the vulnerability if configuration management is not in place. Given Natacha’s research results it was clear we needed to update the current libraries. Configuration management means keep them up to date and eliminate the ones we don’t need. Developers can no longer afford to use third-party libraries without also keeping track of the libraries' updates and security profiles. We won’t know the configuration management costs until we complete the initial updating of existing libraries. Based on our survey, the majority of users in OpenSimulator are Windows users so this set the priority. She submitted a whitepaper for team review and then proceeded with updating third party libraries. The second chart shows her progress made. Great job Natacha and Frank! The team we will continue that work for all three versions but this is a methodical and incremental process. New source code is not in the current repository but will be updated when testing is completed. This will likely coincide with the repository move to Gitea. Frank, what do you have to share about the future viewer projects?
