I installed Ubuntu alongside Windows 10 on my computer (by the way I hate Windows with a passion and I'm so happy I found Linux. Never going back to Windows.)  From the beginning nautilus never worked.  Being new at this I thought that it was the way Linux worked.  I was trying to open folders on my desktop and nothing happened.  The only way to open folders was to open by "files".  How can I fix this issue?  I tried reinstalling nautilus but I always get this error message  Nautilus-Share-Message: 11:23:25.561: Called "net usershare info" but it failed: Failed to execute child process “net” (No such file or directory)
When typing either of the commands nautilus . or xdg-open . into terminal, they execute correctly, but with a warning:  Nautilus-Share-Message: Called "net usershare info" but it failed: Failed to execute child process “net” (No such file or directory)   As I say, it opens the file manager correctly and I can detect no further problems. There are several instances of users experiencing this message in other questions , but each of the questions either addresses a side-issue I'm not experiencing, or simply goes unanswered.    What does this message mean, and can I do anything to prevent it?
DropDown list onchange event and AJAX in MVC I want to programmatically create a site using custom web templates in sharepoint 2010.  In 2007 I used to get a   SPWebTemplate template = site.GetCustomWebTemplates(LCID)[number];   and used this SPWebTemplate in  SPWeb newSite = web.Webs.Add(url, title, description, LCID, template, true, false);   This worked quite well for 2007. But in 2010 the site templates are saved into the solution store  SPSite.Solutions   which only returns SPUserSolution objects and not SPWebTemplates.  So my question is: How can I programmatically create sites using the site templates from the solution store.    UPDATE: I tried to use  SPWeb newSite = web.Webs.Add(url, title, desc, LCID, templateName, true, false);   where templateName is a string like '{Template-GUID}#TemplateName', but it still does not work. It throws the following error:  Critical error: File or arguments not valid for site template '{4a2d8952-a0af-49a6-8f55-46a59c8d68a2}#CustomerSiteTemplate'. Parameter name: WebTemplate    Any other ideas how to create a site based on a SPWebTemplate? Infinite Series $‎\sum\limits_{n=2}^{\infty}\frac{\zeta(n)}{k^n}$ ‎If $f\left(z \right)=\sum_{n=2}^{\infty}a_{n}z^n$ and $\sum_{n=2}^{\infty}|a_n|$ converges then‎, $$\sum_{n=1}^{\infty}f\left(\frac{1}{n}\right)=\sum_{n=2}^{\infty}a_n\zeta\left(n\right)‎.$$ ‎Since if we set $C:=\sum_{m=2}^{\infty}|a_m|&lt;\infty$‎, ‎then‎ $$\sum_{n=1}^{\infty}\sum_{m=2}^{\infty}|a_m\frac{1}{n^m}|\leq\sum_{n=1}^{\infty}\sum_{m=2}^{\infty}|a_m|\frac{1}{n^2}\leq C\sum_{n=1}^{\infty}\frac{1}{n^2}&lt;\infty‎$$ and ‎by Cauchy's double series theorem‎, ‎we can switch the order of summation‎: $$\sum_{n=1}^{\infty}f\left(\frac{1}{n}\right)=\sum_{n=1}^{\infty}\sum_{m=2}^{\infty}a_m\frac{1}{n^m}=\sum_{m=2}^{\infty}a_m\sum_{n=1}^{\infty}\frac{1}{n^m}=\sum_{n=2}^{\infty}a_n\zeta\left(n\right)‎.$$ This shows that $‎\sum_{n=2}^{\infty}\frac{\zeta(n)}{k^n}=\sum_{n=1}^{\infty}\frac{1}{kn(kn-1)}$.  My Questions:  1) It's obvious that $\sum_{n=1}^{\infty}\frac{1}{2n(2n-1)}=\log(2)$, but how can I evaluate $\sum_{n=1}^{\infty}\frac{1}{3n(3n-1)}$?  2) Is there another method to evaluate $\sum_{n=2}^{\infty}\frac{\zeta(n)}{k^n}$? Why do most C programmers name variables like this:  int *myVariable;   rather than like this:  int* myVariable;   Both are valid. It seems to me that the asterisk is a part of the type, not a part of the variable name. Can anyone explain this logic? The title kind of says it all. Is it possible to replace C# with C++ on a game using Unity? I have a geotiff raster image that has a coordinate system with longitudes from 0 to 360. The horizontal center of the image is 180 longitude. See image below:    I want to transform it to EPSG:4326 SRS with -180 180 longtitude range.  And I want the center of the image to be at Greenwich meridian (0). I guess this srs is very widely used. I expect the result look like this:    So I use a gdalwarp command to reproject:  gdalwarp -s_srs '+proj=latlong +datum=WGS84 +pm=180dW' -t_srs EPSG:4326 test_col.tif test_4326.tif   But I only get a tiff with bigger dimensions (more pixels) and EPSG:4326 metadata. The image itself looks the same, as the initial one. But I expect it to swap the hemispheres.  How do I gdalwarp an image to be strictly -180 180 EPSG:4326 with the center in 0 longitude?

C state-machine design "a" or "an" in front of a word beginning with a vowel I was writing a text when I came to say 'a union', then it struck me that I need to change the 'a' to 'an'. But for some reason, 'an union' didn't sound right.   Why doesn't it work? Is it because its a mass noun, instead of a regular noun? Can I bring a pack of razor blades on a plane?

Before you yell at me - it was closed, turned off and it wasn't a lot of water, the laptop was wet only on the top and under - not inside.  Today I've turned him on. At first battery wasn't recharging for some reason, but SMC reset fixed the problem.  At the first booting speaker was like talking to me, hard to explain but it was weird. Also only right speaker was "talking", despite the fact that only left side of the laptop was watered. Then there was no sound at all, not from the speakers, nor from the headphones. Also microphone's not working. USB ports are okay. The water was spilled from the left side of the laptop. I know this is hardware issue, and something's broken, but I want to be 100% sure. No it's not muted. I've also tried NVRAM reset a few times, but it doesn't fix the problem :(  There might be one factor, before spilling, my laptop "died" for the first time (battery energy ran off), but I doubt it's the case. (but hey, every info matters, right?)  It wouldn't be weird for me, if only left speaker wouldn't work, but built-in microphone not working is kinda weird in this case, isn't it?  I just want to ask you guys, what else can I check, before I'll be 100% sure it's dead inside?  I've plugged in external microphone - it's not working too. Why are all the textures in my file pink? I need a number of different full-page DOM samples for my qUnit test suite Creating Text Elements using ArcPy? Add scratches to a material in Cycles? Can a spell scroll be upcast using a higher-level spell slot? For example,  says:  You create three glowing darts of magical force. Each dart hits a creature of your choice that you can see within range. A dart deals 1d4 + 1 force damage to its target. The darts all strike simultaneously, and you can direct them to hit one creature or several. At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the spell creates one more dart for each slot level above 1st.  If a PC finds a scroll of Magic Missile, can it be cast as you would with a level 2 slot (and what are the conditions to do this)? Or will it always be level 1? Relationship between Partial Harmonic Sum and Logarithm. How to wait in bash for several subprocesses to finish and return exit code !=0 when any subprocess ends with code !=0? How to wait in a bash script for several subprocesses spawned from that script to finish and return exit code !=0 when any of the subprocesses ends with code !=0 ?  Simple script:  #!/bin/bash for i in `seq 0 9`; do   doCalculations $i &amp; done wait   The above script will wait for all 10 spawned subprocesses, but it will always give exit status 0 (see help wait). How can I modify this script so it will discover exit statuses of spawned subprocesses and return exit code 1 when any of subprocesses ends with code !=0?  Is there any better solution for that than collecting PIDs of the subprocesses, wait for them in order and sum exit statuses? Is it possible to follow a user automatically? I've been looking around and I can't seem to find an automatic (i.e. buzz- or Twitter-like) way to follow users inside Stack Exchange. Why haven't the developers added such a feature? It could help beginner users follow other beginners with the same interests. We would be able to learn from each others' questions and pitfalls. Also, it would reduce double posting.
