Controlling serial port through a webapp(PHP, javascript) using MySQL and Python | 10,899,487 | 0 | 1 | 743 | 0 | javascript,php,python,mysql,serial-port | You might also want to check out pySerial (http://pyserial.sourceforge.net/). You might also want to think about you sampling rates, i.e. how much data are you going to be generating and at what frequency. in other words how much data are you planning to store. Will give you some idea of system sizing. | 0 | 0 | 0 | 1 | 2011-07-22T14:50:00.000 | 2 | 0 | false | 6,791,799 | 0 | 0 | 1 | 2 | Wanted to get some feedback on this implementation.
I'm developing an application on the PC to send and receive data to the serial port.
Some of the data received by the application will be solicited, while other data unsolicited.

Upload file to NodeJS server every 30 minutes | 6,798,369 | 2 | 0 | 598 | 0 | python,perl,file-upload,node.js | If this isn't part of other program logic, a simple curl --upload-file <file> <url> would do the job. If not, like Dan Grossman commented, any language capable of opening a socket and write HTTP headers and body would work (all assuming your node.js server is speaking http). | 0 | 0 | 0 | 1 | 2011-07-23T04:50:00.000 | 2 | 1.2 | true | 6,798,305 | 0 | 0 | 1 | 2 | I'm trying to figure out the best way to upload a file to a NodeJS(any server I guess, but just being specific) every 30 mins.
I was thinking about using perl or python to acheive this, or even NodeJS or a CGI script?
Would it be best to just create a multi-part form?
Trying to figure out the best practice.
Thanks. |
Upload file to NodeJS server every 30 minutes | 6,798,370 | 1 | 0 | 598 | 0 | python,perl,file-upload,node.js | I might recommend crontab for a job like this. It's a sort of job-scheduler for the operating system, and is designed for 'do this job every so often' tasks. | 0 | 0 | 0 | 1 | 2011-07-23T04:50:00.000 | 2 | 0.099668 | false | 6,798,305 | 0 | 0 | 1 | 2 | I'm trying to figure out the best way to upload a file to a NodeJS(any server I guess, but just being specific) every 30 mins.

Should one minify server code when it's in production? | 6,811,003 | 74 | 36 | 3,747 | 0 | php,python,ruby,perl,node.js | You're not going to have any improvement as the whitespaces and all formatting are lost when your server side code is translated to machine code (or interpreted).

Should one do the same with server code? I usually have a lot of comments in my server files. But I have never heard about people doing so.
Wouldn't the server run faster if the code was optimized in the same way? |
