SensorBase Blog

I’ve been working on getting ready to move sensorbase or parts thereof to the thumper machine, but there are a lot of things to do before hand. I’ve had to move the old file structure to thumper for testing purposes, which seems to be taking quite a long time since it is so big.
People had also been complaining of SOAP issues, I’m unsure of where the problems may have arisen, but after restarting a few processes, the problem seems to have been quelled. If anyone knows more about this, people feel free to enlighten me.
Today we also got an email regarding an unresolved issue with the sensorbase website certificates for SSL. It is something that is been taken care of, and should be dealt with soon.
During one night this weekend I’ll be taking mysql down for a short period to perform a dump of the database in order to start the transfer process to thumper. This should happen at a relatively light load time for sensorbase, and will hopefully not affect the vast majority of users. If you’re planning on collecting data throughout the weekend, I ask that you consider changing your days, or not try to slog any data after 10pm this weekend. I’ll probably post something on the website when things actually happen. The reason why I can’t give a firm time/date yet is that I don’t know when I’ll have access to the thumper machine as I am still waiting for this, but at the same time, I want to be able to start this process as soon as possible. Thanks for your understanding.

Again, let me know of any questions or problems that arise.

Just fyi everyone, we’re installing Trac on the server so we can better stage the site before making changes final. There might be some small interruptions while we restart the apache to enable Trac. Please let me know if you encounter any problems. Thanks

Just FYI, I’m starting the copying of the MySQL database from the frontend server to another server that will possible serve as the backend. There should be no significant impact on users of the site, please let me know if you experience any. Thanks.

It seems that the XML parsing feature for json location data that takes in something like this:

{”gps_module_name”:”Assisted GPS”,”latitude”:34.069239132371,”longitude”:-118.4429105267, “altitude”:124,”horizontal_accuracy”:60.79863357544,”vertical_accuracy”:65, “fix_time”:”2008-07-08T23:11:34.398000Z”,”speed”:0.5400000214577}

was not working. Going over the code, it seemed that the functionality had not been inserted over a course of rewritting the surrounding code. I added in the functionality again, and it seems to be working fine with the test cases I’ve provided. Let me know if you encounter any problems.

Hey All,

Just  updating everyone on what might be some potential questions about what’s been going on with Sensorbase lately.

From Friday to Sunday, users of Campaignr experienced issues with uploading media content through Campaignr. This was a serious problem that came about as a result from SVN access being set up for all to use. Unfortunately, any media data that was collected between midafternoon on Friday and late afternoon on Sunday was probably not saved. I apologize for this issue, and can assure you that it has been taken care of and will no longer be an issue.

Also, it has been brought up that Sensorbase has been down several times throughout this last week. The first time this occurred it was due to a back up issue brought up while updating the folder structure for database media files. This will not be an issue in the future. Other outages have been caused by our local network operators need to upgrade the firewall which our server is behind. These are short interruptions which shouldn’t have affected many users, but still necessary to state. There should be one such interruption today between 12-12:30pm. As far as I know, it should be the last one for a while.

Lastly, I’m currently investigating a bug in the json_location xml parser; if anyone is trying to use this feature, please ignore the debugging output. I would recommend not trying this feature out until I state that it is fixed anyways.

Hey all,

Now you can all have access to the Sensorbase code to play with on your own. Enjoy! Currently you only have read access to the repository, but if you’re someone we know who likes to contribute, send me an email and we might be able to discuss adding you on the list of contributors. Check it out at: SVN access

Hey guys,

Just letting you know that there might be a few slow downs for a few days caused by the restructuring of Sensorbase’s database folder structure and the like. Just letting it be known, please let me know if you experience a huge problem because of it. Sorry for the inconvenience!

P.S. This should definitely be good for the site in the long run, so please bare with us.
