The following Python script is extracted from /usr/lib/python2.7/dist-packages/Mailnag/plugins/libnotifyplugin.py  In the script, the command ('zenity --info --text="You got new mail"') is not run.  How do I make it run? I want it to run when mail_count &gt; 0 The lines under if mail_count &gt; 1: are run properly.  if mail_count &gt; 0:     import os     os.system('zenity --info --text="You got new mail"')     if mail_count &gt; 1:     summary = _("{0} new mails").format(str(mail_count))     if (mail_count - i) &gt; 1:         body = _("from {0} and others.").format(senders)     else:         body = _("from {0}.").format(senders) else:     summary = _("New mail")     body = _("from {0}.").format(senders)   I put the following "Testing.py" script into /usr/lib/python2.7/dist-packages/Mailnag/plugins/Testing.py and ran it, which did bring up the "You got new mail" message.   #!/usr/bin/env python2 import os os.system('zenity --info --text="You got new mail"')
I'm currently studying  and Python programming. I just want to know how I would go about executing a Linux command in Python. The commands I want to execute are:  echo 1 &gt; /proc/sys/net/ipv4/ip_forward iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-port 8080   If I just use print in Python and run it in the terminal will it do the same as executing it as if you was typing it yourself and pressing Enter?
How do comment @replies work? Possible to bake texture to new UV map? I have a finished model where the UV maps overlap - lots of wood that isn't detailed to be particular to the model.    I'd like to re-map the texture so that specific details can be added. I'd like to rebuild the UV map into non-overlapping islands, without losing the current texture application, and preferably without manually pulling apart the islands.  Is this possible? Was or is? Confusion My question is for example when closing a call with a customer which is the proper way? "Once again my was (name), have a great day!" or "Once again my is (name), have a great day!"   need this cleared up lol "This edit would have to be a suggested edit" / edit button grayed out A couple of times recently when I attempted to edit a post while reviewing it from the "First Posts" queue, I received the following message when I tried to submit the form:  This edit would have to be a suggested edit. (x)   This is a rather cryptic message, considering that edits made from a review are suggested edits, subject to the same peer review process. There was no indication of how the edit would have to be submitted differently, much less why. I searched both help and meta for more information about this message, but came up empty.  The first time it happened, after I cancelled out I saw that someone else had just edited the post, so I thought maybe that's why I couldn't submit an edit from the review (and wondered why, if that's the case, the error message didn't just say that instead of telling me something that doesn't make any sense - that the edit I'm trying to suggest can't be submitted because it would have to be a suggested edit). However, the second time I received this message (last night, for this question: ), there was no other edit. So, I clicked the No action needed button and tried to edit the post outside the review process, only to discover that the edit link was grayed out.   I see several explanations of possible causes for graying out the edit link here: . However, there was no tooltip when I hovered over the disabled link, and the edit queue was in the single digits.  A few minutes later, I noticed that the edit link was no longer grayed out, so I edited the post and my edit was accepted.   My best hypothesis based on my experience with the error so far and the explanations I've read here at meta is that someone submitted a suggested edit while I was reviewing the post, which (a) caused me to get the cryptic error message and (b) caused the edit link to be grayed out when I accessed the post the normal way. Then a few minutes later, the suggested edit was rejected, opening up the question for new edit suggestions.  Rather than speculating about it and trying to determine the answer scientifically, it would be helpful if someone could give me the answer (as Seinfeld fans might put it, "Why don't you just tell me why I can't edit the post?"). It would be even more helpful if the error message itself provided the explanation, or if the message were defined somewhere in the help pages. But, at the very least, hopefully there will soon be an answer on meta to enlighten people who scratch their chins over this in the future. :) Schengen refusal formulae can be difficult to understand sometimes.    When an applicant receives a refusal with "Justification for the purpose and conditions of the intended stay was not provided", what does it mean? Is there an editor or IDE (or a script) for substituting the TeX-Commands $ and $$ for opening and closing math regions into the corresponding LaTeX-Commands \(,\) and \[,\]? I'm sure there is a tool - and I'm searching for. I think, this will result in better readable code. A simple search and replace wont do that - but with regular expressions, that should not be problem. I simply do not want to invent the wheel a second time. My cursor is moving by every selection by large increments!  Normally when I use Blender, I am able to select and move objects to any coordinate. Now, all of the sudden, when I select an object or mesh the selection moves by an inch or so in each direction.  How do I reset it to normal? If $$(1+ \cos A) (1+ \cos B) (1+\cos C)= y = (1- \cos A) (1-\cos B) (1-\cos C)$$ then prove that $$y = \pm \sin A \sin B \sin C$$ For $p,q$ prime and $p \neq q$ show that $C_p \times C_q \cong C_{pq}$ Here are my thoughts so far:    $C_p = \langle x \mid x^p =e\rangle$ $C_q = \langle y \mid y^q =e\rangle$ $C_p \times C_q$ has elements of the form $(x^a,y^b)$ There are $p$ possible values for $x^a$ and $q$ possible values for $y^b$. So there are $pq$ possible elements in $C_p \times C_q$. $C_{pq} = \langle z\mid z^{pq} = e\rangle$ and there are $pq$ elements in this group. For an isomorphism from $C_p \times C_q$ to $C_{pq}$ we send $(e,e)$ to $e$ to ensure that the identities are mapped to each other. However, I'm not sure how to define an isomorphism for the other elements.

Mute conversations on Skype I'm in a conversation and I don't really want to leave because the people there keep adding me back so it's just whatever. But I would like to mute the conversation or something like I do on Facebook so I won't take notifications or anything from there unless I press on the group and see what's going on. Because for now I have my Skype having a new notifications every half a second.  Any solutions to that? Is there a limit to a total number of months a holder of UK multiple entry visitor visa can spend in UK per calendar year? A relative of mine has received a multiple-entry UK visa for 2 years. Is there a particular limit on how many months in total per year she can stay in UK? The way I understand the current rule is that such visitors can enter UK as many times as they want as long as they do not stay for longer than 6 months per single visit. However, does this mean that if she stayed with us for 5 months and went back home for 1-2 months, she could come and stay for another 5 months? I heard that it is advisable to spend only 180 day per calendar year in UK and not more, but I could not find that rule in any official UK Home Office documents. Thanks in advance for any info about this. Is $29$ the only prime of the form $p^p+2$? I'm looking for a way to access raster layers in an Esri File-GeoDatabase without using ArcObjects or ArcPy, specifically I would like to access the raster layers with GDAL. I understand that the GDAL FileGDB and OpenFileGDB give access to vector datasets within File-GeoDatabases, and that ESRI's own FileGDB C++ API does not support raster access.   Is anyone out there aware of any open source solutions? Is $\sum_{n=1}^\infty \frac{\sin(2n)}{1+\cos^4(n)}$ convergent? As I was just checking this 'child prodigy' out on Youtube, I stumbled upon  video, in which Glenn Beck asks the kid to do the following proof:    Further on, the kid starts sketching a proof (without a shadow of a doubt regarding the accuracy of his solution ) including the Integral Test. I don't know much about improper integrals since I just finished highschool, but this integral approach seemed, intuitively, pretty inaccurate to me since this is not a strictly decreasing function. Then I found this out from Wikipedia !   Furthermore, the blunt assessment that the series are convergent seems dubious as well..Upon a few computations of my own(mostly partial sums) , I tend to believe that the series are, in fact, divergent .  Can anyone suggest a rigurous take on this problem (easy as it may seem to some amongst you) ? What are the tradeoffs involved in taking a postdoc at a top university versus an assistant professorship at a non-top university? How can I make ffmpeg be quieter/less verbose? By default ffmpeg sends a whole lot of messages to stderr: when built, how it was built, codecs, etc, etc, etc.  How can I make it quieter?  I've tried -v 0 (and -v 10 since the documentation just coyly says Set the logging verbosity level. with no indication of what the range of inputs is) -- still not quiet.  I've tried -loglevel quiet -- still not quiet.  I should mention, I'm looking for "quieter," not "no output ever".  If there's an error I want to see it, but I don't need to hear about ffmpeg's configuration every. single. time. Is there proof that the DSA construction, also used by ECDSA, is secure assuming that discrete logarithms in the relevant group representation are difficult? Is it possible to do vector calculus in Mathematica?
