Hi all,
Please forgive any newbiness or blockheadedness of mine in this
question. I suspect that as usual I'm in way over my head.
I have a weather server (Dell Latitude D520 laptop), running Mint 11,
collecting data from my weather station and uploading it to my Web
server (located at my ISP). The weather server software is weewx,
written in Python.
I want to include, on the Web page, a picture of the view to the north
from my house, and update it frequently (say hourly during daylight
hours; updating together with the weather data every few minutes, I
assume, would blow my data allowance).
I've got an Ai-Ball webcam (www.thumbdrive.com) and can see, on the
weather server, what the camera is looking at. So far, so good.
To take a snapshot, I need to allow a Java app to run on the weather
server. I then have to click and save a JPG. As far as I can tell,
each succeeding JPG will be saved with a different file name. I imagine
that I can write a script to delete the JPG as soon as it's uploaded to
the Web server, and configure weewx to upload the only JPG in a
particular folder.
How do I automate the process of taking the snapshot?
Also, not long after Java loads and starts running on the weather
server, the cooling fan starts running at full bore. CPU use goes to
100%. Kill the Java app, the CPU use goes back down and the fan runs
down. (I'm not blaming the poor old Dell or Mint; my Mac, which is
quite recent, does the same.) Is there any way around this?
Again, sorry if the questions are dumb - there's no useful tech support
on the Ai-Ball Web site and I don't know how to Google the problem. I
do not object to being directed to reference books if the solution may
lie there.
Cheers,
===Andrew
