Windows service in production?
by snorble March 20, 2015

March 20, 2015

Anyone know of a Python application running as a Windows service in production? I'm planning a network monitoring application that runs as a service and reports back to the central server. Sort of a heartbeat type agent to assist with "this server is down, go check on it" type situations. If using Visual Studio and C# is the more reliable way, then I'll go that route. I love Python, but everything I read about Python services seems to have workarounds ahoy for various situations (or maybe that's just Windows services in general?). And there seem to be multiple layers of workarounds, since it takes py2exe (or similar) and there are numerous workarounds required there, depending on which libraries and functionality are being used. Overall, reading about Windows services in Python is not exactly a confidence inspiring experience. If I knew of a reference example of something reliably running in production, I'd feel better than copying and pasting some code from a guy's blog.

Dear Group, I am trying to use Gensim for Topic Modeling with LDA. I have trained LDA but now I want to test it with new documents. Should I use doc_lda = lda[doc_bow] or is it something else? If any one of the esteemed members of the group can kindly suggest? Thanking in Advance, Regards, Subhabrata

We cannot stop the great mass of people sending HTML mail, but there is no reason why we have to *read* HTML email. Even today, most mail clients will send a plain text part that contains the same content as the HTML part, and any decent mail client can be set to prefer the plain text part in preference to rendering the HTML. For those few cases where there is no plain text part[1], the better mail clients (such as mutt) will include an option to dump the raw HTML to plain text, minus all the tags. Last but not least, for the *vanishingly small* number of cases that has no plain text part, and the formatting of the text dump is unreadable, or where the formatting of the HTML is actually essential to understanding the post, then you have a choice of pressing Delete on the message or rendering the HTML. But rendering HTML should never be the default. [1] Or worse, one of those shitty messages that include a plain text part that says "Your mail program cannot read this email. Please upgrade to a better mail program." -- Steven

Re: drawing with the mouse with turtle

These docs are for Python 2.7 turtle, but they may be applicable to older versions as well: http://docs.python.org/library/turtle.html#turtle.ondrag I quote: >>> turtle.ondrag(turtle.goto) Subsequently, clicking and dragging the Turtle will move it across the screen thereby producing handdrawings (if pen is down). That's probably all you need to do. -- Steven
