Answer : curl: command not found is a big hint, you have to install it with : apt-get update; apt-get install curl Ran into this same issue while using the CURL command inside my Dockerfile. As Gilles pointed out, we have to install curl first. These are the commands to be added in the 'Dockerfile'. FROM ubuntu:16.04 # Install prerequisites RUN apt-get update && apt-get install -y \ curl CMD /bin/bash So I added curl AFTER my docker container was running. (This was for debugging the container...I did not need a permanent addition) I ran my image docker run -d -p 8899:8080 my-image:latest (the above makes my "app" available on my machine on port 8899) (not important to this question) Then I listed and created terminal into the running container. docker ps docker exec -it my-container-id-here /bin/sh If the exec command above does not work, check this SOF article: Error: Cannot Start Container: stat /bin/sh: no such file or directory...

Answer : While I can't explain exactly why this happens, I think I can show how to get around it. The ICONINFO struct contains two members, hbmMask and hbmColor, that contain the mask and color bitmaps, respectively, for the cursor (see the MSDN page for ICONINFO for the official documentation). When you call GetIconInfo() for the default cursor, the ICONINFO struct contains both valid mask and color bitmaps, as shown below (Note: the red border has been added to clearly show the image boundaries): Default Cursor Mask Bitmap Default Cursor Color Bitmap When Windows draws the default cursor, the mask bitmap is first applied with an AND raster operation, then the color bitmap is applied with an XOR raster operation. This results in an opaque cursor and a transparent background. When you call GetIconInfo() for the I-Beam cursor, though, the ICONINFO struct only contains a valid mask bitmap, and no color bitmap, as shown below (Note: again, the red border has been adde...

Answer : From what I've got you can't do exactly that same card flip between activities. BUT, as you might already know you need overridePendingTransition() in order to animate transition between activities (doc here). Now all you need is an animation resource to do the trick. I used these: fade_in.xml <?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" > <scale android:duration="200" android:fromXScale="0.0" android:fromYScale="1.0" android:interpolator="@android:anim/accelerate_decelerate_interpolator" android:pivotX="50%" android:pivotY="50%" android:startOffset="200" android:toXScale="1.0" android:toYScale="1.0" /> <alpha android:duration="1" android:fromAlpha="0.0" android:startOffset="200" andr...

Answer : Know this is old but I ran onto it during my search for Nano(V3)'s not uploading so thought might help someone else. Problem is the bootloader - Arduino IDE BUT I Found an easy solution (right under my nose). I realized that my nano's had been uploading just fine then I had finally updated the Arduino AVR Boards from 1.6.20 to 1.6.21. I didn't think there was any problems because it still showed my Nano and ATmega328 etc in the board manager after the change. But the new boards manager has a new ATmega328 processor choice for the Nano. I changed processor: In the Arduino IDE select TOOLS > PROCESSOR > pulldown menu from ATmega328P to "ATmega328P (Old Bootloader)" . Since then, I have uploaded many programs to several different Nano's V3 (Prolofic interace Chipset) without issue. This error message basically shows up for any communication problem, so by itself, it is not all that instructive. The Arduino Nano is supposed to have au...

Answer : No, villagers are not able to use fence gates. I tested this in creative, and they always used a long route with a door rather than a short route with a fence gate. I even blocked off the door and they just stood there. No . Villagers can only open and close wooden doors, but they cannot open and close fence gates. You can, of course, set up a fence gate, but the villagers may try to escape through that opening when you open the fence gate. A better way to trade with villagers is to set up a booth-like thing: F-Fence V=Villager FFF FFF FVFFFFVF FVVVVVVF FFFFFFFF This way, they cannot escape and you can still trade with them. No , they can't. They cannot use any mechanism without the help of redstone or stuff like pressure plates for wooden doors.

Answer : It's not working because you haven't edited [google:baseURL] . Use this string https://www.google.com/search?q=%s EDIT: See comments Edit Sept 2015: This doesn't seem to work any more. There's a better way. If you edit the search string in the Preferences, you won't get autofill results. If you do it this way, you will. Change Chrome's Search Engine to Google.com: http://googlesystem.blogspot.ca/2013/07/change-chromes-search-engine-to.html Type google.com/ncr in the address bar and search for something Close Chrome Launch Chrome again, open a new tab and search for something using Chrome's omnibox. You should see an infobar that asks you: "would you like to search with google.com instead of [your local Google domain]?"

Answer : I hope this is helpful to anybody having trouble understanding computational time complexity for Breadth First Search a.k.a BFS. Queue graphTraversal.add(firstVertex); // This while loop will run V times, where V is total number of vertices in graph. while(graphTraversal.isEmpty == false) currentVertex = graphTraversal.getVertex(); // This while loop will run Eaj times, where Eaj is number of adjacent edges to current vertex. while(currentVertex.hasAdjacentVertices) graphTraversal.add(adjacentVertex); graphTraversal.remove(currentVertex); Time complexity is as follows: V * (O(1) + O(Eaj) + O(1)) V + V * Eaj + V 2V + E(total number of edges in graph) V + E I have tried to simplify the code and complexity computation but still if you have any questions let me know. Considering the following Graph we see how the time complexity is O(|V|+|E|) but not O(V*E). Adjacency List V E v0:{v1,v2} v1:{v3} v2:{v3} v3:{} Ope...

Answer : There are actually two questions on MathOverflow that ask how to cite answers found on MathOverflow. I would recommend following their advice. One of them is a fairly old question, whose answer is somewhat outdated. Summarizing: Even though you may not be legally obligated to show where you got your answer (for example, when MO points you to a theorem already in the literature), it is a good idea — it never hurts to be generous and honest. (And if you're copying part of an answer, not citing it would be plagiarism.) There is a little button for each answer that says "cite" and will give you a citation. You might have to reformat this to make it fit in your journal's bibliography style. Perhaps the person who posted it actually found it elsewhere and can provide a reference to you. Alternately, if you are willing to be publicly known here, you can find a way to exchange emails and hence give proper credit to the individual(s). In the past, I'...

Answer : If it "doesn't care about the output", couldn't the exec to the script be called with the & to background the process? EDIT - incorporating what @AdamTheHut commented to this post, you can add this to a call to exec : " > /dev/null 2>/dev/null &" That will redirect both stdio (first > ) and stderr ( 2> ) to /dev/null and run in the background. There are other ways to do the same thing, but this is the simplest to read. An alternative to the above double-redirect: " &> /dev/null &" I used at for this, as it is really starting an independent process. <?php `echo "the command"|at now`; ?> To all Windows users: I found a good way to run an asynchronous PHP script (actually it works with almost everything). It's based on popen() and pclose() commands. And works well both on Windows and Unix. function execInBackground($cmd) { if (substr(php_uname(), 0, 7) =...

Answer : Create a credentials file at any path where you can access this path from web service application e.g. C:\awsfile\credentials but remember don't give any extension this file File should contains following data. [default] aws_access_key_id=[your_access_key] aws_secret_access_key=[your_secret_key] After this you need to set the path in appsetting tag in the Web.config file: <appSettings> <add key="AWSProfilesLocation" value="C:\awsfile\credentials" /> <add key="AWSRegion" value="us-east-1" /> </appSettings> In AWS Explorer for Visual Studio you can create user profiles that give you different permissions on AWS, then you can choose which profile you want to use in AWS Explorer. These profiles are available only to your Windows user account, if anyone else uses your computer then they will have to create their own profiles. Any software that you run under your user account can also use these profiles. ...

Answer : When you create an instance of your class, the _frame instance variable is automatically initialized, even before the init method is called. Since _frame is a C-struct ( CGRect ), its memory is cleared to all zeroes. This results in a CGRect with all zero values. CGRectNull is a special, non-zero CGRect . So your check using CGRectIsNull() will never be true. Using CGRectIsEmpty is a more proper check for this. Try - (CGRect)frame { if (CGRectIsEmpty(_frame)) _frame = CGRectMake(0,0,60,60); return _frame; } Here is an updated answer for Swift 4. You are able to simply use CGRect's isNull boolean property to check for CGRectNull now: let someRect = CGRect.null print(someRect.isNull) // true
