Hello,

Sorry for the trouble. If you could email me the usernames and project names of the students with missing work, I would be happy to look into it! My email is brian.broll@gmail.com.

We also make frequent backups so even if there was a bug in the system (although I don't know of any current saving issues), we would be happy to retrieve the latest backup of the student's project.

Brian

Hello,

Sorry for the trouble! I have never seen this behavior. Can you open the browser console and see if there are any errors there? Are you on a school network with any firewall restrictions?

Also, we recommend using Google Chrome (although I don't think that is likely to be the culprit here). Would you mind trying it with Google Chrome just to be sure?

Brian

PS - Directions on opening the browser console can be found here.

NetsBlox has been updated to version 1.8.0. Most notably this includes:

• In projects using multiple roles, "Save" has been replaced with "Save Role" to make it clear that it only saves the current role that you are editing (any other users on different roles will not be automatically saved).
• Added historical stock price information to IEXTrading service
• Miscellaneous bug fixes and improvements

For more detailed information, check out the release notes!

Hello,

We don't currently have any metrics about the uptime but uptime hasn't been an issue when we have used it in classes at Vanderbilt or any of our studies/summer camps.

NetsBlox is a fork of Snap! with its own backend support (message routing and such requires more backend support). If you are interested, the client code is available at https://github.com/NetsBlox/Snap--Build-Your-Own-Blocks and the rest is at https://github.com/NetsBlox/NetsBlox.

There currently isn't a plan for a text-based equivalent. The codification features should be supported in NetsBlox since it is an extension of Snap!. However, we have been considering other platforms for deployment of NetsBlox projects (such as robotics platforms).

If you decide that NetsBlox might be a good fit for your class and have any more questions feel free to either post them here or just email us directly! Although this platform is convenient, I respond faster to email :)

Our contact email is akos.ledeczi@vanderbilt.edu and my email is brian.broll@vanderbilt.edu

Yeah, it is currently available. Collaborators can be added using the cloud dropdown (only available if you are logged in).

After the other user accepts the invitation, he/she should see the project under "Shared with me" in the open project dialog.

Opening this project should then allow both users to work on the same project! One gotcha is that the users will only see the same code if they are both occupying the same role. As a project can have multiple roles -- or Snap-like subprojects -- they have to make sure they are not occupying different clients as then nothing will be synchronized (and it shouldn't be).

From the "Room" tab, you should see two usernames listed under the currently occupied role as shown below:

I hope this helps! If you have any questions, feel free to ask! (Sorry for the late response)

One interesting feature for creating training videos from a project could be creating a video from a replay history

NetsBlox has been updated to v1.0.0! Most notably this includes:

• synchronous messaging blocks (send msg and wait and send response)
• updated room editor
• service names have been updated to a consistent syntax (backwards compatible, of course!)
• additional RPCs:
  • Pixabay
  • ThingSpeak
  • StreamFlow

Sending an http message from netsblox should work. I am not really familiar with the Snap4Arduino server... have you tried using something like postman to make sure that the snap4arduino server can receive messages?

Also, don't hesitate to check out the demos at https://netsblox.org/tutorials!

Merging the code bases from each would likely be a pretty significant undertaking.

However, we have plans to add network enabled robots (controlled wirelessly) in NetsBlox. Basically, our idea is to leverage the existing network to communicate with swarms of network enabled robots. As the server is the intermediary which knows about all the robots, it can emulate sensors as well for the users. This would let the users write code which uses a variety of advanced sensors on the robot which are simply emulated on the server (so the robots can remain affordable and feasible for classroom environments).

We have also been considering taking this one step further. Since we have a server managing the communication between the users and the robots' environment, we could also use a projector to add virtual entities which are simply projected on the environment. As the server is emulating the robot sensors, it can make this virtual entity able to be sensed and interactive with respect to the robots.

Let me know if you decide to try to merge Snap4Arduino and NetsBlox and I can provide some more insight into the NetsBlox code base.
