Fortunately I have another system with VS, and by sharing the disk was able to create a working project on that disk with the other system, and then see it fail with my development system, so I knew that the compile and code was ok. Then I tried running just with IIS, no VS, and when it failed too that told me that it wasn't really VS, it was deeper.\u003c/p\u003e","answer_count":"1","comment_count":"0","creation_date":"2016-05-04 18:01:01.43 UTC","last_activity_date":"2016-05-04 18:01:01.43

But, basically what my problem is the following. \nI am taking Bitmap and making it gray scale. It works nice if i do not reduce the number of bits and I still use 8 bits. However, the point of the hw I have is to show how the image changes when I reduce the number of bits holding the information. In the example bellow I am reducing the binary string to 4 bits and then rebuilding the image again. The problem is that the image becomes black. I think is because the image has mostly gray values (in the 80's range) and when I am reducing the binary string I am left with black image only. It seems to me that i heave to check for lower and high gray scale values and then make the more light-gray go to white and dark gray go to black.

For instance, if I want to perform Hadoken in Street Fighter, I tell the program \"hey, if I press 'P' or 'Joystick 1 Button 10', invoke the following keyboard events respectively 'down arrow' in the first (1/60) millisecond, 'down+right arrow' in the next (1/60) millisecond, 'right arrow' in the next (1/60) millisecond and finally 'Z' in the next (1/60) millisecond\".\u003c/p\u003e\n\n\u003cp\u003eSo what I am looking for here is different from JoyToKey in the following aspect:\u003c/p\u003e\n\n\u003col\u003e\n\u003cli\u003eI am looking for how to write a JoyToKey-like program in \u003cstrong\u003eJava\u003c/strong\u003e.\u003c/li\u003e\n\u003cli\u003enot limited to Joystick only.

VirtualAddress, PointerToRawData?","body":"\u003cp\u003eI've been trying to do this for about two days, with no success. I have been reading over many PE file format tutorials to no avail.\u003c/p\u003e\n\n\u003cp\u003eI map a 32 bit executable into memory via CreateFileMapping which works perfectly. My program then loops through the section headers, and checks the characteristics against my default characteristics (to make sure the section is executable and is code). If it is true the program returns the (PIMAGE_SECTION_HEADER) pointer to that section header (program works perfectly so far).\u003c/p\u003e\n\n\u003cp\u003eNow that I have the pointer, there are two specific entries to the structure that have baffled me, and that is PointerToRawData and VirtualAddress, when I cout the entries;\nVirtualSize = 4096, PointerToRawData = 1536.\u003c/p\u003e\n\n\u003cp\u003eFrom what I have read in PE documentation, is that PointerToRawData is a supposed offset (RVA???) to the first byte of data in the section on disk (am I correct?), and is a multiple of a alignment value (512). The question is what do I set this value to, to obtain a pointer which I can use to access the section's data. On a memory-mapped file would it be better to use (VirtualAddress value + the imagebase value) to find the first byte of the section?\u003c/p\u003e\n\n\u003cp\u003eAnother point of confusion is VirtualSize vs SizeOfRawData. This has confused me because in this article - \u003ca href=\"http://msdn.microsoft.com/en-us/library/ms809762.aspx\" rel=\"nofollow\"\u003ehttp://msdn.microsoft.com/en-us/library/ms809762.aspx\u003c/a\u003e, it says \"The SizeOfRawData field (seems a bit of a misnomer) later on in the structure holds the rounded up value\" yet my VirtualSize is greater than my SizeOfRawData value which has led to confusion on which one I should use.\u003c/p\u003e\n\n\u003cp\u003eThe object of this program is to find the executable section (.text section) and perform a bitwise operation on all the bits in the section, and end the operation before the next section.\u003c/p\u003e\n\n\u003cp\u003eI don't want it to seem like I expect a spoonfeed, I just want some clarifications.\u003c/p\u003e\n\n\u003cp\u003eThank you for your time/help, it is appreciated.\u003c/p\u003e","accepted_answer_id":"14036278","answer_count":"1","comment_count":"0","creation_date":"2012-12-26 05:12:38.843 UTC","last_activity_date":"2012-12-26 05:49:05.327 UTC","last_edit_date":"2012-12-26 05:18:24.53 UTC","last_editor_display_name":"","last_editor_user_id":"1850910","owner_display_name":"","owner_user_id":"1850910","post_type_id":"1","score":"0","tags":"c++|c|portable-executable","view_count":"1646"} +{"id":"31416051","title":"When to use deleteOnExit and not delete?","body":"\u003cp\u003eFirst of all I am not asking for difference between the two.

I am new to JS and GoogleMaps API v3, and have successfully followed their tutorials to get this far. However, I'd like to have an infowindow with custom content appear based on which marker is clicked, and I cannot figure out how to do this. I'd also like to have this be possible with around 100 markers, so I'd like to know the best way to do this as well without things getting too messy. To be clear, there are 3 types of icons, but there will eventually be many markers associated with each icon, so I will need content linked to each \"feature\".

The benefit of \"off-side rule\" syntax over \"curly brackets\" syntax is compromised if you have to parenthesize just about everything and manually style it to look structured. I am pretty sure there are many Haskellers who consider it unclean, as observed in monoid-based libraries having a meaningless instance of monad (and an empty value to pass around) to exploit the \u003ccode\u003edo\u003c/code\u003e syntax.

(In fact the issue is worse with parentheses than with brackets because you need to insert almost twice as many special characters to represent the structure of function application.) It would also drastically reduce the chance of missing symbols by mistake, which is exactly the advantage of off-side rule languages over curly bracket languages. In the best scenario, missing or misplacing parentheses, brackets, or commas will result in a compile-time error and worst, a faulty program that does something wild and unintended.\u003c/p\u003e","accepted_answer_id":"24297313","answer_count":"2","comment_count":"3","creation_date":"2014-06-18 08:55:51.793 UTC","last_activity_date":"2014-06-19 01:27:22.153 UTC","last_edit_date":"2014-06-19 01:27:22.153 UTC","last_editor_display_name":"","last_editor_user_id":"2079797","owner_display_name":"","owner_user_id":"2079797","post_type_id":"1","score":"0","tags":"haskell|syntax","view_count":"132"} +{"id":"30479959","title":"Sending string having quote in it as post method without backslash","body":"\u003cp\u003eWe all know that sending quote as parameters will be replaced by a backslash quote.\u003c/p\u003e\n\n\u003cp\u003eI have 2 pages: \u003cem\u003elogin.html\u003c/em\u003e and \u003cem\u003eindex.php\u003c/em\u003e\u003c/p\u003e\n\n\u003cp\u003eThe login page must send parameters to the index page using the POST method.\u003c/p\u003e\n\n\u003cp\u003eLet's say I'm sending\u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003eusername --\u0026gt; X'D\npassword --\u0026gt; xxx\n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003eThe username automatically transfers to \u003ccode\u003eX\\'D\u003c/code\u003e .. but I want it to remain \u003ccode\u003eX'D\u003c/code\u003e.\u003c/p\u003e\n\n\u003cp\u003eHow is it possible to receive the data without the backslash?\u003c/p\u003e\n\n\u003cp\u003eI want the backslash to be removed before arriving to the index page not using the htmlspecialchar in the index page or something.\u003c/p\u003e","answer_count":"2","comment_count":"5","creation_date":"2015-05-27 10:33:23.497 UTC","last_activity_date":"2015-07-01 08:40:06.937 UTC","last_edit_date":"2015-05-27 10:47:16.073 UTC","last_editor_display_name":"","last_editor_user_id":"711206","owner_display_name":"","owner_user_id":"4944184","post_type_id":"1","score":"2","tags":"php|html|post|backslash|quote","view_count":"557"} +{"id":"12387446","title":"query rpm from apache+php with selinux","body":"\u003cp\u003eI have a php script that runs in an apache serveron a RHEL5 installation.

I'll give the map canvas a minimum height of say 200px, just in case, but otherwise it should force the footer to bottom of the page without scrolling (unless the screen is short enough for the 200px minimum to require scrolling).\u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003e\u0026lt;body\u0026gt;\n\u0026lt;div id=\"wrapper\"\u0026gt;\n \u0026lt;div id=\"header\"\u0026gt;Title\u0026lt;br /\u0026gt;of\u0026lt;br /\u0026gt;variable\u0026lt;br/\u0026gt;height\u0026lt;/div\u0026gt;\n \u0026lt;div id=\"body\"\u0026gt;\n \u0026lt;div id=\"map-canvas\"\u0026gt;\u0026lt;/div\u0026gt;\n \u0026lt;/div\u0026gt;\n \u0026lt;div id=\"footer\"\u0026gt;\n Footer\u0026lt;br /\u0026gt;of\u0026lt;br /\u0026gt;variable\u0026lt;br /\u0026gt;height\n \u0026lt;/div\u0026gt;\n\u0026lt;/div\u0026gt;\n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003e\u003c/p\u003e\n\n\u003cp\u003eHere is a Fiddle showing it very close using flex approach...

Our application is a 64 bit one. But the third party just offers a 32-bit dll. To make things simpler for us, we have written a wrapper (basically a web api project) around this third party dll. We have added this as a service reference in our main app. We are using VS 2015, and have explicitly checked the box in \u003cem\u003eTools-\u003eOptions-\u003eProjects-\u003eWeb Projects-\u003eUse 64 bit IIS\u003c/em\u003e.

To overcome this, we have hosted the wrapper project as 32 bit web api in our QA environment, and we directly consume it. Now, I have been asked to look into a few issues in it.

After that, I have a boolean flag called doesIntersect which is initalized to false. I loop through all the hitboxes and check if the current one intersects() with any others. If so, I set the flag to true. Then, after it checks, if the flag is true it resets that location in the array to null and recalls addPopup().

The Linux version uses the \u003ccode\u003etermios\u003c/code\u003e module which isn't supported on Windows so I'm using \u003ccode\u003ePyserial\u003c/code\u003e instead. \u003c/p\u003e\n\n\u003cp\u003eThe script starts three \u003ccode\u003ethreads\u003c/code\u003e which repeatedly put ~4MB of data per thread into a queue. My problem is that, with Pyserial, if each thread is reading more than the 4k receive \u003ccode\u003ebuffer\u003c/code\u003e only one or none of the threads actually receives data from \u003ccode\u003e.read()\u003c/code\u003e Below is a little test script to demonstrate my problem. \u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003enumThreads = 3\nreadSize = 4128000\nq = Queue.Queue()\ncomPort = serial.Serial(port = 'COM5', baudrate = 115200)\n\ndef read_task(port, threadID, readSize):\n q.put((threadID, comPort.read(readSize)))\n\nthreads = [threading.Thread(target=read_task, args=(i,) for i in range(numThreads)]\nfor t in threads:\n t.daemon = True\n t.start()\n\nfor t in threads:\n t.join()\n\nwhile 1:\n try:\n _,item = q.get(False)\n print hex(ord(item[0]))\n print len(item)\n except Queue.Empty:\n break \n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003eAt the end I print the hex value of the first byte of each queue element that I get. I do this because I know that if the thread was actually reading data, every byte would be a non-zero value.\u003cbr\u003e\nSo the output would look something like: \u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003e0x94\n4128000\n0x00\n4128000\n0x00\n4128000 \n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003eSo the first thread to call read was able to read data and the other two weren't and just returned a string of 0x00's. Is there anything I can do to get multiple threads to read that much data at one time. \u003c/p\u003e\n\n\u003cp\u003eI took a look at the \u003ccode\u003ekernel32.dll\u003c/code\u003e functions that Pyserial uses in \u003ccode\u003eserialwin32.py\u003c/code\u003e to execute .read() but I have no experience working with win32 API and I'm still fairly new to python so I can't really figure where to go from here.\u003c/p\u003e\n\n\u003cp\u003eI was just told to try to edit the read function in serialwin32 so that it's \"non-overlapping\".

One of the biggest limitations (IMHO) of OrientDB is that the \u003ccode\u003eODatabaseDocumentTx\u003c/code\u003e is not thread-safe, and yet the lifetime of this thing from \u003ccode\u003e.open()\u003c/code\u003e to \u003ccode\u003e.close()\u003c/code\u003e is supposed to represent a single transaction, effectively forcing transactions to occur is a single thread. Indeed, thread-local refs to these hybrid database/transaction objects are provided by default. But what if I want to log in the same thread as I want to persist \"real\" state? If I hit an error, the log entries get rolled back too! That use case alone puts me off of virtually all DBMS's since most do not allow named transaction scope management. /soapbox\u003c/p\u003e\n\n\u003cp\u003eAnyways, OrientDB is the way it is, and it's not going to change for me. I'm using Clojure and I want an elegant way to construct a \u003ccode\u003ewith-tx\u003c/code\u003e macro such that all imperative database calls within the \u003ccode\u003ewith-tx\u003c/code\u003e body are serialized.\u003c/p\u003e\n\n\u003cp\u003eObviously, I can brute-force it by creating a sentinel at the top level of the \u003ccode\u003ewith-tx\u003c/code\u003e generated body and deconstructing every form to the lowest level and wrapping them in a synchronized block. That's terrible, and I'm not sure how that would interact with something like \u003ccode\u003epmap\u003c/code\u003e.\u003c/p\u003e\n\n\u003cp\u003eI can search the macro body for calls to the \u003ccode\u003eODatabaseDocumentTx\u003c/code\u003e object and wrap those in synchronized blocks.\u003c/p\u003e\n\n\u003cp\u003eI can create some sort of dispatching system with an agent, I guess.\u003c/p\u003e\n\n\u003cp\u003eOr I can subclass ODatabaseDocumentTx with synchronized method calls.\u003c/p\u003e\n\n\u003cp\u003eI'm scratching my head trying to come up with other approaches. Thoughts? In general the agent approach seems more appealing simply because if a block of code has database method calls interspersed, I would rather do all the computation up front, queue the calls, and just fire a whole bunch of stuff to the DB at the end. That assumes, however, that the computation doesn't need to ensure consistency of reads.

To address this, protobuf-net provides these frameworks with a \"precompile\" facility,\n which moves all of the impossible / slow steps to a build-time operation, emitting a serialiation dll you\n can reference and use (now very fast etc) from your chosen framework.\n\n More information about the precompiler is here:\n http://marcgravell.blogspot.co.uk/2012/07/introducing-protobuf-net-precompiler.html\n\n protobuf-net also includes a utility for processing \".proto\" files (the schema DSL used by multiple protobuf\n implementations) into C# and VB.NET; this is the ProtoGen tool.\n\n Neither precompile nor ProtoGen need to be deployed with your application.\n\n\n So: what do I need?\n\n example: running on .NET 4.0\n\n solution: copy the files from Full\\net30. Note that protobuf-net does not require any 4.0 features, so using \"net30\" will\n give you all of protobuf-net including WCF support (which is the difference between \"net20\" and \"net30\").\n\n\n example: running on Silverlight 4\n\n option 1: copy the files from Full\\sl4, and accept that it isn't quite as optimal as it could be - but perfectly fine\n for light-to-moderate serialization usage.\n\n option 2: copy the files from CoreOnly\\sl4, and use \"precompile\" (in the Precompile folder) at build-time to generate\n a serialization assembly (this also needs to be referenced and deployed from you application).\n\n Additional:\n\n Note that each framework contains 3 files:\n\n - protobuf-net.dll the library itself\n - protobuf-net.xml intellisense xml, used by thre IDE when developing\n - protobuf-net.pdb debugging symbols, useful when debugging\n\n Of these - the only one you **need** to deploy is the dll; the pdb may be useful for investigating crash reports. The\n xml is used only by the IDE.\n\n Folders:\n\n cf20 compact framework 2.0\n cf35 compact framework 3.5\n ios iPad/iPod/iPhone via MonoTouch\n net11 regular .NET 1.1 (excluded generics)\n net20 regular .NET 2.0 (excludes WCF hooks)\n net30 regular .NET 3.0 or above (including 3.5, 4.0, 4.5, ...)\n netcore45 windows store apps / windows runtime 4.5\n portable portable class library (phone 7, xna, silverlight)\n sl4 silverlight 4 or above\n wp71 windows phone 7.1\n unity specific to unity (avoids missing \"interlocked\" methods)\n\n License:\n\n The full license is shown separately, but boils down to \"do what you like with it, don't sue me,\n don't blame me if it goes horribly wrong, don't claim you wrote protobuf-net\"\n\n Finally:\n\n All feedback welcome.\n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003eI want to us it with unity, the unity folder or most of the other folders listed including 'full' dont seem to exist...

For example, say I, a user of the app, want to send another user of my app a message or a geopoint or some other form of data. I know the first step would be posting the data to Parse, which I don't have a problem with. But then, how would the other user know there is data to retrieve and also how would they go about retrieving it. Are push notifications the proper and only way of letting the recipient's app know its being sent something? When the recipient app knows there is data posted intended for it to retrieve, how does it go about locating it with a PFQuery? Does the posting app need to supply the receiving app with a UID of some form that the receiving app can then use in its query to locate the data? This is kind of the last puzzle piece for my app and unfortunately it's the only thing Parse didn't make clear to me. It is more than likely user error on my part not finding the correct documentation but, app to app communication is key in most apps and so I need to figure out the defacto way that Parse accomplishes this.

I am still hoping I've missed something obvious, though! \u003c/p\u003e\n\n\u003cp\u003eI did some digging and found that Play uses Spring's \u003ccode\u003eDataBinder\u003c/code\u003e class to do the actual binding.

However, it seems that Play Framework's \u003ccode\u003eForm\u003c/code\u003e object does not allow access to the DataBinder, apart from setting allowed fields.

The code is below.\u003c/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat does the test do?\u003c/strong\u003e\nIt creates a table with 100 rows. A data column is blank in all but one. It then runs a Coldfusion query 10 times, half using cfqueryparam and half using a simple string. It returns a list with the response time for each. When I run this, apart from the initial calls, the parameterized query runs much more slowly (by about 10-100 times).\u003c/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's happening in SQL Server?\u003c/strong\u003e\nI can see no difference in SQL server. In both cases the plan cache indicates virtually identical plans (one is obviously parameterized) and the profiler shows fast responses for both.

But I can't do this directly, since I don't control \u003ccode\u003edirectionsService.route\u003c/code\u003e. It also strikes me that this is already a roundabout way to handle the problem; I'd much rather pass \u003ccode\u003earg1, arg2, arg3\u003c/code\u003e and their parameters to a function which can handle the async stuff and clean up when all have returned. Any suggestions on what is the best way to go about this?\u003c/p\u003e\n\n\u003cp\u003eI could dig my hole deeper by adding another global and updating it between calls. I could write a wrapper for directionsService.route which wraps it in another layer of callback indirection.

This leads to an error at compile time.\u003c/p\u003e\n\n\u003cp\u003eIn my application, I have a collection of several objects (e.g. \u003ccode\u003eD1\u003c/code\u003e, \u003ccode\u003eD2\u003c/code\u003e), that have a common base class \u003ccode\u003eB\u003c/code\u003e. They are held together and kept track of by means of a \u003ccode\u003estd::vector\u0026lt;B*\u0026gt;\u003c/code\u003e.\u003c/p\u003e\n\n\u003cp\u003eThe derived objects introduce \u003ccode\u003edouble\u003c/code\u003e-returning functions that need to be called on a regular basis. The base class keeps track of these functions by means of a \u003ccode\u003estd::vector\u0026lt;double(B::*)(void)\u0026gt;\u003c/code\u003e. The whole chain is utilized in the second to last line of the main function.\u003c/p\u003e\n\n\u003cp\u003eTherefore, I needed to cast the function pointers when adding them to the vector, as is done in the constructor of the derived classes \u003ccode\u003eD1\u003c/code\u003e and \u003ccode\u003eD2\u003c/code\u003e. his is successful in case of \u003ccode\u003eD1\u003c/code\u003e, but not in case of \u003ccode\u003eD2\u003c/code\u003e, as \u003ccode\u003eB\u003c/code\u003e is a virtual base of \u003ccode\u003eD2\u003c/code\u003e. As I learned, a static cast does not work in this case (error message 1), because the deriving classes \u003ccode\u003eD21\u003c/code\u003e and \u003ccode\u003eD22\u003c/code\u003e only have a pointer to the instance of \u003ccode\u003eB\u003c/code\u003e. However, a dynamic_cast also leads to an error at compile time (error message 2), saying that the target is not of pointer type.\u003c/p\u003e\n\n\u003cblockquote\u003e\n \u003cp\u003e\u003cstrong\u003eerror message 1\u003c/strong\u003e: error: pointer to member conversion via virtual base 'B' v.push_back(static_cast(\u0026amp;D2::f2));\u003c/p\u003e\n \n \u003cp\u003e\u003cstrong\u003eerror message 2\u003c/strong\u003e: error: cannot dynamic_cast '\u0026amp;D2::f2' (of type 'double (class D2::\u003cem\u003e)()') to type 'double (class B::\u003c/em\u003e)()' (target is not pointer or reference)\u003c/p\u003e\n\u003c/blockquote\u003e\n\n\u003cp\u003eI'd like to know how, if at all, I can perform the desired cast. If not I'd like to know why such a thing is not possible.\u003c/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eEdit: Some background:\u003c/strong\u003e I integrate a system of ordinary differential equations numerically. The derived classes represent the individual equations of the system, and each derived class computes its own state. By collecting the classes in the vector \u003ccode\u003eo\u003c/code\u003e, I can quickly modify the system of equations. The vector \u003ccode\u003ev\u003c/code\u003e in the base class is needed for output purposes. During integration, each subsystem also takes care of its own output through the base class. The diamond arose because I separated two often used pieces of code into two individual classes.\u003c/p\u003e\n\n\u003cp\u003eArguably, there are other ways to design the class hierarchy, and there are other ways to achieve my goal (in this case I made the function \u003ccode\u003ep\u003c/code\u003e in \u003ccode\u003eB\u003c/code\u003e virtual, and re-implemented it in the deriving classes).

Why does \u003ccode\u003eAdd(new Explosion(16,16,this))\u003c/code\u003e work in GameState but \u003ccode\u003egame-\u0026gt;Add(new Explosion(16,16,game))\u003c/code\u003e doesn't work inside my object?\u003c/p\u003e\n\n\u003cp\u003eI ran it through gdb and it tells me:\u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003eProgram received signal SIGSEGV, Segmentation fault.\nAt c:/program files (x86)/codeblocks/mingw/bin/../lib/gcc/mingw32/4.4.1/include/c++/bits/stl_tree.h:482\n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003eThe code that throws the error is:\u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003e_Link_type\n _M_begin()\n { return static_cast\u0026lt;_Link_type\u0026gt;(this-\u0026gt;_M_impl._M_header._M_parent); } //this line\n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003eSo to sum it up I have no idea why my pointers break the STL... and I get that grave feeling that I'm missing something very basic and its causing all these headaches.

First, I enabled module-level caching, which had a slight benefit, but not quite enough. So I then enabled page-level caching.

I've determined that errors are stored in the session, then displayed on a page via JDocumentRendererMessage.

For example:\u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003efunc setup() {\n for i in 0...10 {\n let sprite = SKSpriteNode(imageNamed: \"FirstSpriteName\")\n sprite.position = etc...\n }\n}\n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003eor preload the sprite when I initialize the class: \u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003elet firstSprite = SKSpriteNode(imageNamed: \"FirstSpriteName\")\n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003eand later in the \u003ccode\u003esetup()\u003c/code\u003e func: \u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003efunc setup() {\n for i in 0...10 {\n let sprite = firstSprite.copy()\n sprite.position = etc...\n }\n}\n\u003c/code\u003e\u003c/pre\u003e","accepted_answer_id":"42373281","answer_count":"1","comment_count":"0","creation_date":"2017-02-21 16:45:31.29 UTC","last_activity_date":"2017-02-21 16:55:32.767 UTC","last_editor_display_name":"","owner_display_name":"","owner_user_id":"4360150","post_type_id":"1","score":"0","tags":"swift|performance|sprite-kit|skspritenode","view_count":"55"} +{"id":"43292240","title":"Does append() create a copy of the arguments or append the actual argument's reference to the list?","body":"\u003cp\u003eWhen I run \u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003ex = [0, 1]\ny = [2, 3]\nx.append(y)\nx[2][1] = 4\nprint y\n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003eit prints out\u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003e[2, 4]\n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003eSo, basically, is it appending the reference of the argument to the list? not a copy that is totally unrelated to the argument?\u003c/p\u003e","answer_count":"0","comment_count":"2","creation_date":"2017-04-08 09:14:35.207 UTC","last_activity_date":"2017-04-08 09:16:41.633 UTC","last_edit_date":"2017-04-08 09:15:14.573 UTC","last_editor_display_name":"","last_editor_user_id":"100297","owner_display_name":"","owner_user_id":"6915916","post_type_id":"1","score":"0","tags":"python|append","view_count":"323"} +{"id":"43999377","title":"Python cannot find package setuptools","body":"\u003cp\u003eI get the error\u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003eCould not import setuptools which is required to install from a source distribution.\nTraceback (most recent call last):\nFile \"/home/comp1/anaconda3/lib/python3.5/site-packages/pip/req/req_install.py\", line 387, in setup_py\nimport setuptools # noqa\nFile \"/home/comp1/anaconda3/lib/python3.5/site-packages/setuptools/__init__.py\", line 10, in \u0026lt;module\u0026gt;\nfrom setuptools.extern.six.moves import filter, filterfalse, map\nImportError: No module named 'setuptools.extern.six'\n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003eeven though the same code runs perfectly on a variety of our computers.

Furthermore the hierarchy can split more table via a join, so the type that represent the row will depend on the existence of the record in the other table.

The Select times are faster out of the composite key table since I have to apply secondary indexes and use 'ALLOW FILTERING' in order to get the proper records back with the standard key table (I know I could do this in code but the concern is that I am dealing with some massive data sets and that will not always be practical or possible). \u003c/p\u003e\n\n\u003cp\u003eAm I declaring the Column Family or the Primary Key wrong for what I am trying to do?

We will need to be able to run a large project with a team of 3-4 artists and 10+ programmers. We use Perforce source control system for storage of all code and assets. We need to be able to manage a project with multiple shared resources and multiple people (artists \u0026amp; programmers) working on screens and controls.\u003c/p\u003e\n\n\u003cp\u003eOur problem is as follows:\u003c/p\u003e\n\n\u003cp\u003eWe want to be able to create skinned graphical custom components, such as buttons, sliders, checkboxes as well as more complex controls such as tables and game specific elements.\nWe want to be able to share graphics assets in a single location and allow multiple artists and coders to work on shared components simultaneously. We need all of this to be stored in a Perforce source control repository.\u003c/p\u003e\n\n\u003cp\u003eFor AS3 code this is all fairly straight forward. It works like any other codebase and we have set up FlashBuilder and FlashDevelop projects.\u003c/p\u003e\n\n\u003cp\u003eNow, the options seem to be as follows:\u003c/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eCreate a flash project or projects. The problem here is that all of the assets are copied into AuthortimeSharedAssts.fla.

This will allow work on multiple shared components because individuals can update a small discrete FLA file and this will automatically update a larger shared librar. The problem is that this does not allow sharing of graphics assets, which means that, if an artist updates a graphic, this does not filter down to individual flash files.\u003c/p\u003e\u003c/li\u003e\n\u003cli\u003e\u003cp\u003eUse the XFL format.

Basically, the user can design a shoe by picking available options.\u003c/p\u003e\n\n\u003cp\u003eThe trick is that the left and right shoe must have the same size, among other properties, but things like color, shoe lace texture, etc. can be independent properties per shoe. (I figured this was a decent way for me to practice object manipulation and inheritance).\u003c/p\u003e\n\n\u003cp\u003eThe user starts off with designing the right shoe; when the \"swap\" button is clicked to look at the left shoe, the user currently sees a copy of the right shoe (but inverted). \u003cstrong\u003eOnly on the first swapping of shoes is the left shoe generated and made an exact copy of the right shoe. From then onwards, unique options per shoe orientation are preserved.\u003c/strong\u003e Then, if the user makes specific changes to \u003cem\u003ethat\u003c/em\u003e left-shoe model, and then switches to the right shoe, the user is supposed to see the exact same right shoe that they had originally designed before they clicked the \"swap\" button.\u003c/p\u003e\n\n\u003cp\u003eSo if their right shoe had red laces, they switch to the left shoe view and make the left shoe have a blue lace, then when switching back to the right shoe the user should see red laces!\u003c/p\u003e\n\n\u003chr\u003e\n\n\u003cp\u003e\u003cstrong\u003eTechnical Details\u003c/strong\u003e \u003c/p\u003e\n\n\u003cp\u003eWhen I was writing the code for my main project I was running into trouble with the unique options being perserved. For example, if I made the laces green for the left shoe, the right shoe would always have green laces. Troubleshooting down to the problem was easy because the only time the right shoe was losing it's unique options, such as a red lace, was when I would set the lace color for the left shoe.\u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003econsole.log(\"THE RIGHT LACE BEFORE: \" + rightShoe.laceId);\nleftShoe.laceId = 'green';\nconsole.log(\"THE RIGHT LACE AFTER: \" + rightShoe.laceId);\n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003eWhat would log to the console was:\u003c/p\u003e\n\n\u003cblockquote\u003e\n \u003cp\u003eTHE RIGHT LACE BEFORE: red\u003c/p\u003e\n \n \u003cp\u003eTHE RIGHT LACE AFTER: green\u003c/p\u003e\n\u003c/blockquote\u003e\n\n\u003cp\u003eEven though I wasn't changing the \u003ccode\u003erightShoe\u003c/code\u003e, it was being changed whenever I changed the \u003ccode\u003eleftShoe\u003c/code\u003e property.\u003c/p\u003e\n\n\u003cp\u003eSo I went back to where I first define the \u003ccode\u003eleftShoe\u003c/code\u003e object, which is when the user clicks \"swap\" for the first time in the life of the script (My amateur thought was \u003cem\u003ewhy propagate and fill the \u003ccode\u003eleftShoe\u003c/code\u003e object if the user possibly never customizes the left shoe?\u003c/em\u003e Maybe it's being unnecessarily stingy with data, I don't know). From then onward, \u003cem\u003eI never redefined the \u003ccode\u003eleftShoe\u003c/code\u003e to be a copy of \u003ccode\u003erightShoe\u003c/code\u003e\u003c/em\u003e or vice versa. I figured that I was getting hung up by the fact that I was probably doing object referencing and, just like with other languages, I was changing the \u003cem\u003ereference\u003c/em\u003e and not the value.\u003c/p\u003e\n\n\u003cp\u003eBefore coming to SO with my troubles, I wanted to make a JSFiddle to recreate the problem. Being that my project is lengthy (around ~1500 lines, including some \u003cstrong\u003eTHREE.js\u003c/strong\u003e for graphics), I did my best to emulate the process. And so \u003ca href=\"https://jsfiddle.net/fuayzgxn/2/\"\u003ehere it is\u003c/a\u003e.\u003c/p\u003e\n\n\u003cp\u003e\u003cem\u003eExcept the JSFiddle worked exactly as I expected it to!\u003c/em\u003e The left model preserved it's unique attribute and data set to that attribute. So, I did a little more digging and read about the \u003cstrong\u003eObject.assign()\u003c/strong\u003e method. So in my original project code (\u003cem\u003enot\u003c/em\u003e the fiddle), I changed this:\u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003eleftShoe = rightShoe;\n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003eto this:\u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003eleftShoe = Object.assign({}, rightShoe);\n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003eAs excited as I am to have finally gotten this to work, I am equally amused and perplexed because I don't understand why my JSFiddle didn't need the \u003ccode\u003eassign()\u003c/code\u003e method but my identical project code did.

Just for now all windows in private browsing mode share same cookies, storage and such, so you can still be tracked even in private mode, if you don't reset it too often. How often is too often is a question — ideally, you should reset after each visited site, because each site could mark you. It would be cool, if there was an ability to adjust granularity of private mode — like, separate private windows or tabs one from another.\u003c/p\u003e\n\n\u003cp\u003eI thought about tagging all URLs with some kind of tab-unique long random tag — so \u003ccode\u003ehttp://example.com/foo\u003c/code\u003e opened in two separate private tabs becomes \u003ccode\u003ehttp://example.com.AYZYXP/foo\u003c/code\u003e and \u003ccode\u003ehttp://example.com.QUSOFX/foo\u003c/code\u003e. From the browser's point of view, these are two distinct domain names, with their own caching rules, cookies, DOM storage, IndexedDB, FlashPlayer pesistence or anything else. From webpage's point of view it's necessary to keep the impression both tabs are \u003ccode\u003ehttp://example.com/foo\u003c/code\u003e, because exposing the tag will defy the idea of tagging — and that's why I need location rewriting.\u003c/p\u003e","answer_count":"1","comment_count":"8","creation_date":"2015-02-07 07:42:25.443 UTC","favorite_count":"1","last_activity_date":"2015-02-08 10:51:29.287 UTC","last_edit_date":"2015-02-07 12:20:44.557 UTC","last_editor_display_name":"","last_editor_user_id":"472695","owner_display_name":"","owner_user_id":"472695","post_type_id":"1","score":"3","tags":"javascript|security|firefox|firefox-addon|fingerprinting","view_count":"381"} +{"id":"28285380","title":"R ReporteRs: Editing Existing Slides","body":"\u003cp\u003eI have a presentation in pptx format that I need to update frequently with graphs that I generate with an R script.

I am assuming this isn't an emulator issue.\u003c/p\u003e\n\n\u003cp\u003eI followed \u003ca href=\"https://msdn.microsoft.com/en-us/library/windows/apps/xaml/jj709907.aspx\" rel=\"nofollow\"\u003ethis guide\u003c/a\u003e in order to intercept push toast notifications while the app is running. However, I only want to suppress the toast notification when the app is in the foreground. It should still display when another app is in the foreground. So I wrote the following handler in \u003ccode\u003eApp.xaml.cs\u003c/code\u003e (and subscribed to the PushNotificationReceived event):\u003c/p\u003e\n\n\u003cpre\u003e\u003ccode\u003eprivate async void OnPushNotification(PushNotificationChannel sender, PushNotificationReceivedEventArgs e)\n {\n string msg = \"\";\n if (e.NotificationType == PushNotificationType.Toast)\n {\n await CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =\u0026gt;\n {\n if (Window.Current.Visible)\n {\n msg += \" Toast canceled.\";\n e.ToastNotification.SuppressPopup = true;\n }\n });\n\n if (true) // actually determines if it's a certain type of toast\n {\n await CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, async () =\u0026gt;\n {\n ConfirmationContentDialog confirmationDialog = new ConfirmationContentDialog();\n confirmationDialog.SetMessage(\"Please confirm that you like turtles.\" + msg);\n await confirmationDialog.ShowAsync();\n });\n }\n }\n }\n\u003c/code\u003e\u003c/pre\u003e\n\n\u003cp\u003eSo this works, in the sense that I only see the \"toast canceled\" message when the app was in the foreground when receiving the push notification. When I'm on the start screen or somewhere else I always get the toast. This is good. However, when the app is in the foreground, sometimes (usually after sending the second push) the toast shows up anyway (even though \"Toast canceled\" displays). But sometimes it doesn't. It's rather inconsistent.\u003c/p\u003e\n\n\u003cp\u003eThis is leading me to believe that due to the await, sometimes the toast gets through before the code gets run on the UI thread to check whether the app is visible or not. However, I can't access Window.Current.Visible from here without using the dispatcher. I even tried \u003ccode\u003eCoreApplication.MainView.CoreWindow.Visible\u003c/code\u003e but that gives me \"interface marshalled for different thread etc\" exception. Speaking of which, I don't understand how \u003ccode\u003eCoreApplication.MainView.CoreWindow.Dispatcher\u003c/code\u003e can be called from anywhere but \u003ccode\u003eCoreApplication.MainView.CoreWindow.Visible\u003c/code\u003e not? How does that even work.\u003c/p\u003e\n\n\u003cp\u003eAnyway, how do I fix this?

Groups contain multiple people, and a person can be part of multiple groups. It's a many-to-many, but bear with me. Basically, there's a subquery that will return a set of groups. From that, I can join to People (which requires additional joins across other tables) to get all of the people from those groups. However, I also need to know all of the groups that those people are in, which means joining back to the Groups table again (several more joins) to get a superset of the original subquery. There are additional joins in the query as well to get other pieces of relevant data, and the cost is adding up in a very ugly way. I also need to return information from both tables, so that rules out a number of techniques.\u003c/p\u003e\n\n\u003cp\u003eWhat I'd like to do is be able to start with the People table, join it to Groups, and then compare Groups with the subquery. If the Groups attached to one person has one match in the subquery, it should return ALL Group items associated with that person.\u003c/p\u003e\n\n\u003cp\u003eEssentially, let's say that Bob is part of Group A, B, and C. Currently, I start with groups, and let's say that only Group A comes out of the subquery. Then I join A to Bob, but then I have to come back and join Bob to Group again to get B and C.

We have to start with a filtered Group set, join to People, then come back to get all of the Groups that the People are associated to.\u003c/p\u003e\n\n\u003cp\u003eWhat I'd like to do is start with People, join to Group, and if ANY Group that Bob is in returns from the subquery, ALL should be returned, so if we have Bob joined to A, B, and C, and A is in the subquery, it will return three rows of Bob to A, B, and C as there was at least one match. In this way, it could be treated as a one-to-many relationship if we're only concerned with the Groups for each Person and not the other way around.
