"When creating JavaScript objects with properties, why is this code necessary?",
"I am reading about JavaScript prototypes here. Under the Object.create header, some code is written out to illustrate creating objects with prototypes and certain properties:\n\nvar person = {\n kind: 'person'\n}\n\n// creates a new object which prototype is person\nvar zack = Object.create(person);\n\nconsole.log(zack.kind); // => ‘person’\n\n\nI then encountered this:\n\nvar zack = Object.create(person, {age: {value: 13} });\nconsole.log(zack.age); // => ‘13’\n\n\nInstead of passing {age: {value: 13} }, I passed {age: 13} because it seemed simpler. Unfortunately, a TypeError was thrown. In order to create properties of this object like this, why do we have to pass {age: {value: 13} } rather than just {age: 13}?"

"Using connector c++ to access MYSQL database (How to add a path to my standard search directory)",
"I am relatively new to programming&C++ and just began learning about MYSQL. I have been searching for a couple of days but couldn't find a solution. I usually use Cygwin&VIM&g++ to write, compile and run codes that I write. \n\nMy goal is to retrieve data from MYSQL database that I've set up on my laptop and be able to run a simple algorithm on that data and possibly update the database.\n\nI went into MYSQL's website and went through tutorials and found an example here. I have Boost, Connector, MYSQL server lib downloaded. When I run it, I get an error saying 'connection.h' was not found. I'm sure this is because when I compile it, g++ does not have the location of the library added to the search path that it goes through. The example has something like:\n\n\n #include <cppconn/conneciton.h>\n\n\nwhere these angled brackets means it is going to search (after the current directory) the standard search directory. I am guessing I have to add a new path (the location of where the libraries are) so that the compiler looks at that standard directory and compiles the header.\n\nThrough googling I am thinking in g++ I can use -Ldir -I to add a new search path but I don't get how to use it. Can anyone kindly explain/show me (by example) how to get over with this problem? :("

"Is it bad practice to use C-like static variables in Objective-C?",
"All I want to do is make a utility class for my (stream capture) app that grabs settings from my website. I want to call it from other files as a simple [RemoteConfig updateSettings]; \n\nMy goal is to use this remote configuration utility without making an object for every situation where I grab remote settings.\n\nThe information around static/class variables and methods in Objective C is hazy and very opinionated, so after a lot of experimenting, I got this to work. But it looks funny, which makes me think something is incorrect. \n\nRemoteConfig.h simply declares the +(void) updateSettings method.\n\nThis is my RemoteConfig.m:\n\n#import \"RemoteConfig.h\"\n\nstatic NSMutableData* _configData;\nstatic NSString* url = @\"http://local.namehidden.com:90/json.html\";\nstatic int try;\n\n@implementation RemoteConfig\n\n+(void) updateSettings\n{\n NSString *identifier = [[[UIDevice currentDevice] identifierForVendor] UUIDString];\n\n //Create URL request\n NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]\n cachePolicy: NSURLRequestReloadIgnoringCacheData\n timeoutInterval: 10];\n\n [request setHTTPMethod: @\"POST\"];\n NSString *post = [NSString stringWithFormat:@\"id=%@\", identifier];\n NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding];\n [request setHTTPBody:postData];\n\n NSURLConnection* connection = [NSURLConnection connectionWithRequest:request\n delegate:self];\n [connection start];\n}\n\n///////////////////////////// DELEGATE METHODS ///////////////////////////////////\n\n+(void)connection:(NSConnection*)conn didReceiveResponse:(NSURLResponse*)response\n{\n if (_configData == NULL) {\n _configData = [[NSMutableData alloc] init];\n }\n [_configData setLength:0];\n NSLog(@\"didReceiveResponse: responseData length:(%d)\", _configData.length);\n}\n\n/// and so on...\n\n\nIt looks funky, putting C-style variables above the @interface/@implementation. A lot of people say try to use properties, some say do the static method singleton trick, I've seen a little library that handles singletons but this was the simplest solution I found.\n\nMy questions-\n\n\nIs this proverbially bad?\nWhat limitations does this have?\nWhat are the alternatives, and what is best?"

"Android NDK, keeping live C++ objects",
"I've got a following problem. I want to write an Android application, which uses my legacy C++ classes. I have to keep a C++ object alive during the whole application lifetime.\n\nI wrote a similar application in C# and solved the problem by passing a pointer to a C++ class to C# and storing it there using IntPtr. Then, when I wanted to call a method on that object, I simply passed that pointer again to C++, converted to a class pointer and called a method on it.\n\nHow can I achieve similar result in Java and Android NDK? Does Java support storing pointers?"

"Incorrect zoom level for horizontal polyline in a MKMapView",
"I'm using a MKMapView to display a polyline between two coordinates.\nIn order to ensure that the entire polyline is visible in the map view, I'm using its setVisibleMapRect(_:edgePadding:animated:) method.\n\nThis works fine when the polyline I'm drawing is from north to south (or vice-versa):\n\n\n\nHowever, with an east to west (or vice versa) polyline rendered, not all of it is visible, and the user must zoom out in order for it to be fully visible:\n\n\n\n\nIn this test project, the map view is added to a view controller and has its constraints set so that it fills the entirety of its superview.\n\nThe code I'm using to generate the above example is as follows:\n\noverride func viewDidLoad() {\n\n super.viewDidLoad()\n\n mapView.delegate = self\n\n var verticalLine = [CLLocationCoordinate2DMake(40.711043, -74.008243), CLLocationCoordinate2DMake(40.988465, -73.807804)]\n var horizontalLine = [CLLocationCoordinate2DMake(40.798569, -74.269200), CLLocationCoordinate2DMake(40.804152, -73.771390)]\n\n let polyline = MKPolyline(coordinates: &horizontalLine, count: 2)\n mapView.addOverlay(polyline, level: .AboveRoads)\n\n mapView.setVisibleMapRect(polyline.boundingMapRect, edgePadding: UIEdgeInsetsMake(10.0, 10.0, 10.0, 10.0), animated: false)\n\n}\n\n\nHow can I ensure that the entire line is visible when either a vertical or horizontal polyline is rendered?

"Transparency in GD PHP library",

I read through the lubridate package documentation, and since I want to perform arithmetic operations (if this is the right terminology) I believe the duration function is the correct one.\n\nHowever looking at the examples - I am not entirely sure what the syntax is for applying this to a whole column in a large(ish) data from. Since I have 4.5k observations, I'm not sure exactly how to appply this. I don't need an excessive amount of granularity - ideally even hours and minutes are fine.\n\nSo I'm thinking I would want my code to look like:\n\nconversion from factor variable to character string > conversion from character string to duration/as.numeric."

I had no luck trying to get all the old Haskell tools to install and work, I probably had no idea what I was doing. I got as far as installing some dependencies but some dependencies weren't versioned so I had to track each version specifically and I eventually gave up.\n\nI then just updated the dependency versions for libpandoc itself and now I've got all the dependencies built and linked.\n\nThe only remaining issue is that libpandoc needs to be updated to work against the latest Pandoc release (1.10)."

"Why cast the result of pre-incrementation to void in comma separator context?",
"Looking at std::for_each_n's possible implementation:\n\ntemplate<class InputIt, class Size, class UnaryFunction>\nInputIt for_each_n(InputIt first, Size n, UnaryFunction f)\n{\n for (Size i = 0; i < n; ++first, (void) ++i) {\n f(*first);\n }\n return first;\n}\n\n\nI noticed that the part where we typically see i++ (or, the preferred ++i) consists of two operations:\n\n\n++first\n(void) ++i\n\n\nseparated by a comma. While most of it makes sense, the (void) cast seems a little surprising to me. All I can guess is that there could be an overloaded operator , that takes the deduced type of InputIt and Size which would result in some surprising side-effects. Could that be the reason? If yes, are we sure that cast to void solves that issue entirely?"

The linux-virt kernel is much smaller and does not have the 200+MB of firmware files listed as dependencies, so that is the kernel I selected for the VM. However, I now find that there is no zfs-virt package, only zfs-vanilla which installs the vanilla kernel and all the firmware as dependencies.\n\nIs there a zfs-virt package available in perhaps a third party repository? If not, I am not against building the package myself, but I'm relatively new to Alpine so have not yet figured out how its build system works nor if it is possible to build against an already-compiled kernel (in my own past experience, the only way I've successfully built kernel modules is using the source tree of the target kernel)"

"How do I declare an opaque anonymous structure defined in third-party?",
"I am working on a third-party module wrapper. I hope my main header file does not have any third-party related header files. Every parameter type and return type are opaque by only declaring it. But there is a anonymous structure defined like the following:\n\ntypedef struct {\n int x;\n int y;\n int width;\n int height;\n} IppiPoint;\n\n\nI cannot modify the third-party header file. I have no idea to declare it.

"Is there a way to change the default StartPosition on a Windows Form?",
"The default value for StartPosition on Windows Forms is WindowsDefaultLocation, which I understand is determined by the operating system. I always have to change the value to CenterScreen or CenterParent (for modal windows) - the default location is annoying and seems to change every time. Is there a reason why WindowsDefaultLocation is even there or is there a way to change a setting somewhere so that the default is centered?\n\nI don't know about everyone else, but whenever I start an application I would always prefer it to be centered, that way it's easier to work with."
