How to reduce this RadioGroup Code?
Refactoring RadioGroup setter code?
How do I delete all Folders with a specific name (e.g. 128Kbps_Songs) without deleting its files  For example if I have directory "MP3_SONGS" with subdirectories "A", "B", "C" and each subdirectory has MANY directory Contains Film Name "FILM_NAME1", "FILM_NAME2", "FILM_NAME3" in it, In That Each Film NAme I have specific Folder NAme (128Kbps_Songs) in this "128Kbps_Songs" Folder I have That Film mp3 Songs Files  how can I remove the Folder "128Kbps_Songs", in Each Film_Name directory and Have to get these mp3 songs in that FILM_NAME..   ( Have to Delete 128Kbps_Songs Folder in all FILM_NAME without deleting the mp3 Songs in it, have to get the mp3 in FILM_NAME Directory..  MP3_SONGS (Parent Directory) ------ A , B, C  A (Sub Directory1) ------ FILM_NAME1 , FILM_NAME2 B (Sub Directory2) ------ FILM_NAME3 , FILM_NAME4 c (Sub Directory3) ------ FILM_NAME5 , FILM_NAME6  FILM_NAME1 (Directory) ---- 128Kbps_Songs (Directory) ------ FILM_NAME1 (MP3 Files) FILM_NAME2 (Directory) ---- 128Kbps_Songs (Directory) ------ FILM_NAME2 (MP3 Files)  FILM_NAME3 (Directory) ---- 128Kbps_Songs (Directory) ------ FILM_NAME3 (MP3 Files) FILM_NAME4 (Directory) ---- 128Kbps_Songs (Directory) ------ FILM_NAME4 (MP3 Files)  FILM_NAME5 (Directory) ---- 128Kbps_Songs (Directory) ------ FILM_NAME5 (MP3 Files) FILM_NAME6 (Directory) ---- 128Kbps_Songs (Directory) ------ FILM_NAME6 (MP3 Files)  Need Files in: FILM_NAME1 (Directory)  ------ FILM_NAME1 (MP3 Files) FILM_NAME2 (Directory)  ------ FILM_NAME2 (MP3 Files)  FILM_NAME3 (Directory)  ------ FILM_NAME3 (MP3 Files) FILM_NAME4 (Directory)  ------ FILM_NAME4 (MP3 Files)  FILM_NAME5 (Directory)  ------ FILM_NAME5 (MP3 Files) FILM_NAME6 (Directory)  ------ FILM_NAME6 (MP3 Files) Is there a name for function with the exponential property $f(x+y)=f(x) \cdot f(y)$? I was wondering if there is a name for a function that satisfies the conditions  $f:\mathbb{R} \to \mathbb{R}$ and $f(x+y)=f(x) \cdot f(y)$?  Thanks and regards! How do I create a file and mount it as a filesystem? How do I create a file of size 10M, format it with ext3 filesystem and then mount it in /media/fuse?  I tried with  mkfs -t ext3 file   then to mount it  mount -t ext3 file /media/fuse   It didn't work because it said that file wasn't a block device. Can anybody help me? I'm trying to find $\int x^x \, dx$, but the only thing I know how to do is this:  Let $u=x^x$.  $$\begin{align} \int x^x \, dx&amp;=\int u \, du\\[6pt] &amp;=\frac{u^2}{2}\\[6pt] &amp;=\dfrac{\left(x^x\right)^2}{2}\\[6pt] &amp;=\frac{x^{2x}}{2} \end{align}$$  But it's certain that this isn't the correct way to evaluate that, and the answer must be wrong. Error handling in C code What do you consider "best practice" when it comes to error handling errors in a consistent way in a C library.  There are two ways I've been thinking of:  Always return error code. A typical function would look like this:  MYAPI_ERROR getObjectSize(MYAPIHandle h, int* returnedSize);   The always provide an error pointer approach:  int getObjectSize(MYAPIHandle h, MYAPI_ERROR* returnedError);   When using the first approach it's possible to write code like this where the error handling check is directly placed on the function call:  int size; if(getObjectSize(h, &amp;size) != MYAPI_SUCCESS) {   // Error handling }   Which looks better than the error handling code here.   MYAPIError error; int size; size = getObjectSize(h, &amp;error); if(error != MYAPI_SUCCESS) {     // Error handling }   However, I think using the return value for returning data makes the code more readable, It's obvious that something was written to the size variable in the second example.  Do you have any ideas on why I should prefer any of those approaches or perhaps mix them or use something else? I'm not a fan of global error states since it tends to make multi threaded use of the library way more painful.  EDIT: C++ specific ideas on this would also be interesting to hear about as long as they are not involving exceptions since it's not an option for me at the moment... Adding 2 favorite tags at one time combines tag after page refresh I was adding some tags to my favorite tags today and noticed tags being joined together when the page is refreshed.  Steps to reproduce:   Click edit on Favorite Tags Create the first tag and click add [I added django in this case] Add a second tag and click add [I added python in this case] Refresh page  Favorite tags now show previous tags + djangopython   In the edit section, it appears as if the tags are added separately, but when I refresh the page they get joined  OS: MacOSX-10.8  Browser: Chrome, Firefox How to check if Receiver is registered in Android? Replace Line Breaks in a String C# How can I replace Line Breaks within a string in C#? Avoiding getting suspended for voting irregularities? Many times when I read threads, I keep on upvoting for the reason being that if someone has put an effort to write a big answer, s/he/it should get some rewards for it.  I recently saw someone getting suspended for voting irregularities.   So, I was wondering if I use the total amount of votes allowed per day, daily, will I be suspended? I believe I have solved a famous open problem. How do I convince people in the field that I am not a crank? This is frustrating for me. The UV-textures to vertex cols add-on doesn't seem to work despite the specific instructions. Any other tutorials I can find are either very old or very poor.  I'd like to know how to do this in Blender 2.79. I need vertex colors in my ambient occlusion for use in Shader Forge. As a moderator, how do I handle a potentially inappropriate profile picture? Why are downloads destructive in the Star Trek universe? There are numerous places in various Star Trek episodes where references are made to the fact that "downloads" are a destructive operation: you download something from one place, and unless you explicitly made a copy beforehand, what you downloaded is gone from its original storage location and instead appears in some other location. Hence was born the term "copy and download".  There are of course out-of-universe, plot reasons for things happening that way which are exploited from time to time. There is also the out-of-universe explanation of how large media companies feel about people downloading copyrighted works, and a possible out-of-universe explanation that at the time, people in general may not have been intimitely familiar with the implications of the term "download", so they added "copy" to help describe what happens to at least portions of their viewership.  But is there a plausible in-universe explanation for why downloads would be destructive by default, and a specific copying operation would have to be made beforehand so as to not delete the data from its original location?  As for specific examples, these are two that I can think of right now (I'm quite sure there are more):   VOY "Twisted" (S2E06), right near the end, stated by Torres: "Our entire database has been copied and downloaded into somebody else's system." VOY "Message In A Bottle" (S4E14), a little more than five minutes into the episode, the EMH is "downloaded into the transceiver array" for transmission across an alien sensor network to the Prometheus when the latter is in the alpha quadrant, and some 20 minutes into the episode it's established that the EMH is not available in the sickbay and will return later. When testing the following code:  from osgeo import gdal import json   def read_file(filename):     f = gdal.VSIFOpenL(filename, "rb")     if f is None:         return None     content = gdal.VSIFReadL(1, 10000, f).decode('UTF-8')     gdal.VSIFCloseL(f)     return content   gdal.VectorTranslate('out.json', """{   "type": "FeatureCollection",   "features": [       { "type": "Feature", "geometry": { "type": "Polygon", "coordinates": "coordinates":[[[-188.56933593749997,61.58549218152362],[-173.9794921875,61.58549218152362],[-173.9794921875,66.00015035652659],[-188.56933593749997,66.00015035652659],[-188.56933593749997,61.58549218152362]]] } },   ] }""", format = 'GeoJSON', layerCreationOptions = ['RFC7946=YES', 'WRITE_BBOX=YES'])  got = read_file('/vsimem/out.json') gdal.Unlink('/vsimem/out.json')  print json.loads(got)   from this , the file out.json is empty. The folder is with all permissions for writing allowed. When testing the method gdal.OpenEx, is possible to load an object, but still the method gdal.VectorTranslate returns an empty geojson when trying to pass this new loaded object as a srcDS object. Any hint on solving this issue? Trying to identify a science fiction short story from an anthology likely published before 1991.  Aliens invade during a nuclear war (which would be World War III, WWIII, WW3). The warring nations then turn their nukes on the landing sites, but the invasion succeeds.  Believe the setting is in the U.S., possibly Pacific Northwest, but definitely a mountainous region.  Based on negative inference from the aliens' description of humans as fur-less, no-tail, bipeds (or similar), the aliens are apes or monkeys.  The aliens describe Earth as worse than the Hell planet they previously conquered. They see our tanks and think that we can't have more than a few of those to fight with.  Yet the aliens are somewhat benign, as they take some children back to their parents for a stern talking-to after the children run an alien convoy off the road into a chasm by stringing a rope across the road. Closed-form of $\int_0^1 \operatorname{Li}_p(x) \, dx$ MongoDB could not connect local server I had mongdb installed and evrything was working fine. I wanted to delete the mongodb lock. By mistake the directory /var/lib/mongodb/ got deleted.  So, I uninstalled mongo db and installed again. But now i always keep getting this error:  Error: couldn't connect to server 127.0.0.1:27017 at src/mongo/shell/mongo.js:145 exception: connect fail   The error remains same even if I try to login from terminal or rockmongo or my application. I am using ubuntu12.04 and have latest version of mongo. I'm doing a masters course at a different university than I did my undergrad (both in maths). I did well in my undergrad but now I'm finding it very difficult. The shock of the change is hard to cope with.  I'm not just finding it very difficult, but I get zero feedback: we don't have any tests and I was not able to make friends so I don't know how others are finding it. I'm starting to think that I might be an idiot.   How can I build some confidence in my abilities at the same time as I rush and struggle to keep up with the massive rate of new material I need to learn? How might I get myself some reassurance that I can actually pass, or stop worrying about this so much? (I feel terribly guilty using so much money from my family to be here) It's possible that I don't really have a chance at all but knowing that would be fine.
