"Redux - handling really large state object",
"I have a simple react + flask application.\nI want to load some data (~10mb) when the user clicks a button, and then use this data.\nBecause two different components have to interact with this data, i thought ill save the data as a global state using redux.\nWhat i basically have is two components:\n\nhave a button that calls an action to load the large data from the flask server (and save that data into the global redux state)\nuses the data (from the global state)\n\nOnce i did that, i was getting "SerializableStateInvariantMiddleware took 509ms, which is more than the warning threshold of 32ms.", Which made me think this isnt the right way to do so.\nWhat is the right way to handle something like that?\nShould i keep a different smaller state (so i know the "load data" button was clicked), and read that state from the second component and only then load the data into a private state?\n(check if the global state was changed and if it did, call an action and save the data in the private state?)"

"Duplicate function name affecting Jasmine tests in Meteor",
"I have recently started working with Meteor, and trying to start off as I mean to go on by testing well. To this end, I am using the Velocity test runner and using Jasmine for the actual tests. \n\nTake the very simple case where I have a file in the server directory called hello.js, which contains our old favourite\n\nvar helloWorld = function () {\n return \"Hello World\";\n};\n\n\nThen in my test directory, well 'tests/jasmine/server/unit' I have a test file sampleTest.js containing the basic test suite\n\ndescribe(\"Hello World\", function() {\n it(\"should return hello world\", function() {\n expect(helloWorld()).toBe(\"Hello World\");\n });\n});\n\n\nVelocity reports all tests passing, everyone is happy. If I change the original helloWorld function to return something different, the test fails as expected.\n\nIf, however, a second function, of the same name with a different output existed somewhere in the project, e.g.\n\nvar helloWorld = function () {\n return \"Goodbye World\";\n};\n\n\nThen this would break the test, but the other version of it passes the test.\n\nExtrapolating from this simplified example, how then do I ensure each function is uniquely named to avoid this problem? \n\nIs my question more a result of my incomplete grasp of Meteor fundamentals (or JS/testing fundamentals in general)?"

More precisely in smt2 format: \n\n(declare-fun a(Int) Int)\n(declare-fun b(Int) Int)\n(assert (= 1 (a 0)))\n(assert (= 1 (b 0)))\n(assert (xor (and ( = (a 1) (+ (a 0) (* 2 (b 0)))) (= (b 1) (+ 1 (b 0)))) (and (= (b 1) (+ (a 0) (b 0))) (= (a 1) (+ (b 0) 1)))))\n(assert (xor (and ( = (a 2) (+ (a 1) (* 2 (b 1)))) (= (b 2) (+ 2 (b 1)))) (and (= (b 2) (+ (a 1) (b 1))) (= (a 2) (+ (b 1) 2)))))\n(assert (xor (and ( = (a 3) (+ (a 2) (* 2 (b 2)))) (= (b 3) (+ 3 (b 2)))) (and (= (b 3) (+ (a 2) (b 2))) (= (a 3) (+ (b 2) 3)))))\n(assert (xor (and ( = (a 4) (+ (a 3) (* 2 (b 3)))) (= (b 4) (+ 4 (b 3)))) (and (= (b 4) (+ (a 3) (b 3))) (= (a 4) (+ (b 3) 4)))))\n(assert (xor (and ( = (a 5) (+ (a 4) (* 2 (b 4)))) (= (b 5) (+ 5 (b 4)))) (and (= (b 5) (+ (a 4) (b 4))) (= (a 5) (+ (b 4) 5)))))\n(assert (xor (and ( = (a 6) (+ (a 5) (* 2 (b 5)))) (= (b 6) (+ 6 (b 5)))) (and (= (b 6) (+ (a 5) (b 5))) (= (a 6) (+ (b 5) 6)))))\n(assert (xor (and ( = (a 7) (+ (a 6) (* 2 (b 6)))) (= (b 7) (+ 7 (b 6)))) (and (= (b 7) (+ (a 6) (b 6))) (= (a 7) (+ (b 6) 7)))))\n(assert (xor (and ( = (a 8) (+ (a 7) (* 2 (b 7)))) (= (b 8) (+ 8 (b 7)))) (and (= (b 8) (+ (a 7) (b 7))) (= (a 8) (+ (b 7) 8)))))\n(assert (xor (and ( = (a 9) (+ (a 8) (* 2 (b 8)))) (= (b 9) (+ 9 (b 8)))) (and (= (b 9) (+ (a 8) (b 8))) (= (a 9) (+ (b 8) 9)))))\n(assert (xor (and ( = (a 10) (+ (a 9) (* 2 (b 9)))) (= (b 10) (+ 10 (b 9)))) (and (= (b 10) (+ (a 9) (b 9))) (= (a 10) (+ (b 9) 10)))))\n(assert (= (b 10) 461))\n(check-sat)\n(get-model)\n\n\nThe xor operator is used to check if the statement for then holds or the statement in else holds, but not both. So the the variable a or b is bounded to follow only one valid path. Somehow the values sometimes don't seem to obey this rule or they do not change, and I am unable to tell why is this happening. As for example take this output for a, for the step 2 and 3 the value doesn't change, which should not be possible:\n\n (define-fun a ((x!0 Int)) Int\n (ite (= x!0 0) 1\n (ite (= x!0 1) 3\n (ite (= x!0 2) 7 <--- should not be possible but keeps happening\n (ite (= x!0 3) 7 <---\n (ite (= x!0 4) 29\n [...]\n\n\nI don't know if i either am encountering a bug or my logic involved in the solution for this problem is flawed. I tried to use Bounded Model Checking. I would appreciate any help!"

"editing file lines in place python 2.6",
"I have multiple files that I'm iterating through and for each file I check if a pattern exists there or not and the pattern can either exist once or multiple times or it doesn't exist at all. I want to edit the line that has the pattern once the pattern is found and rewrite the line with the pattern only. If the pattern is not there then I close the file without any modifications. \nMy code:\n\nfor root, dirs, files in os.walk('C:/Users/Documents/'):\n for fname in files:\n for line in fileinput.input(os.path.join(root, fname), inplace = 1): \n if re.search(r\"([\\w-d])\", line):\n x=re.sub(r\"([\\w-d])\", r\"(\\1).\", line)\n print line.replace(line,x)\n\n\nThe problem is it changes the pattern fine when it finds it but for the files that doesn't have the pattern it deletes their contents completely. And if the pattern exists in multiple lines, it keeps one line only and deletes the rest. What am I missing?\n\nEDIT\n\nI'm flexible also to use \"open\" or any other method that can solve my problem. My main concern is I don't want to rewrite the lines in files that don't have the pattern. For tracking purposes I want to only modify the files that has the pattern. so far my research online [1] [2][3] shows that I can either write to a temp file and use it later as original file or read all the lines and then write all of them again regardless if the file has the pattern or not. is there a better way of solving this problem?"

"iOS Addressbook: Cannot setup an ABNewPersonViewController in storyboard",
"I have a subclass of ABNewPersonViewController defined in storyboard, and embedded there in a navigation controller, as required by the docs. The navigation controller is itself controlled by a tab bar controller. In the identity inspector, the class has been set to the subclass.\n\nIn the subclassed ABNewPersonViewController I do the test initialization in viewDidLoad: \n\n- (void)viewDidLoad\n{\n [super viewDidLoad];\n self.newPersonViewDelegate = self;\n\n ABRecordRef newPerson= ABPersonCreate();\n CFErrorRef error = NULL;\n ABRecordSetValue(newPerson, kABPersonFirstNameProperty, CFSTR(\"First\"), &error);\n ABRecordSetValue(newPerson, kABPersonLastNameProperty, CFSTR(\"Last\"), &error);\n assert(!error);\n [self setDisplayedPerson:newPerson];\n} \n\n\nIn my subclass I have also implemented the delegate method newPersonViewController:didCompleteWithNewPerson:, but this does not matter.\nWhen I select the tab in the tab bar controller, a black screen is displayed.\nAny idea what I am doing wrong?\nPS: I know how to set it up programmatically, but I would like to do it in storyboard.\n\nEDIT \n\nWhen I do it programmatically, the subclass is initialized by alloc & init. This works correctly. When the subclass is instantiated from storyboard, it receives initWithCoder:. To test it, I implemented initWithCoder: in the following way: \n\n- (id)initWithCoder:(NSCoder*)coder{ \n self = [super init]; \n return self; \n}\n\n\nIn this case, the entry mask of ABNewPersonViewController is indeed displayed, but the navigation bar is not shown empty. I know this initialization hack is wrong, but does anybody know how to do it right? \n\nEDIT \n\nThe navigation bar was not shown, because I set it to hidden. Normally, it is shown, but the buttons \"done\" and \"cancel\" are missing. This is of course no surprise, because the superclass is not initialized by initWithCoder: but by init.\nStill the question is why the entry mask is not shown, but a black screen only."

"EmptyResultSetException not thrown when expected",
"A query is run to retrieve records from a table one-by-one, which are email recipients. After sending an email to a recipient, the status of the sending is updated for the recipient. The table where this status is stored has a relationship with the table used to store the actual messages to be sent. Because I'm using Room, the query for retrieving the message to send gets automatically run again. This will continue in a loop until all the recipients have been sent an email. This works with the Rx stream below. The problem I have is that after the last email is sent, the query is not throwing an EmptyResultSetException, which is what I expect it to do when no more records are found. Without that exception, I have no way of knowing when all the emails have been sent.\n\nval msgToSendPublisher = BehaviorSubject.createDefault(0)\n\nmsgToSendPublisher.flatMap { startPos -> App.context.repository.getMessageToSend() }\n .flatMap { messageToSend ->\n App.context.repository.sendMessage(messageToSend)\n .doOnError {\n messageToSend.failureSending = true\n }\n }\n .zipWith( // 1 second delay between emissions.\n Observable.interval(1, TimeUnit.SECONDS),\n BiFunction { item: MessageToSend, _: Long -> item })\n .flatMap { messageToSend ->\n App.context.repository.storeMessageSent(messageToSend)\n .doOnError {\n messageToSend.failureSending = true\n }\n }\n .subscribeOn(Schedulers.io())\n .observeOn(AndroidSchedulers.mainThread())\n .subscribe(\n { messageToSend ->\n\n },\n { ex ->\n if (ex is EmptyResultSetException) {\n\n } else {\n\n }\n },\n {\n // Done\n }\n )\n\n\nDAO\n\n@Query(\n \"SELECT blah blah blah\"\n)\nfun getMessageToSend(): Observable<MessageToSend>\n\n\nMessageToSend.kt\n\nclass MessageToSend(\n var content: String? = null,\n var chatId: String? = null,\n var firstName: String? = null,\n var lastName: String? = null,\n var totalMessagesToSend: Int? = null\n): MessageRecipientBase()\n\n\nWhat could be preventing EmptyResultSetException from not being thrown? Or is it being thrown but caught somewhere I am not aware of. I have a suspicion that Room only throws this exception when you explicitly run a query. But if a query is run because Room forces a query to run after data in a related table is updated, it is possible that Room may decide not to throw any exception.\n\nNOTE: I've put a breakpoint on each of the doOnError handlers as well as the error handler in the subscriber but none of them get hit."

The recorder library is not my code, but at a high level, it tries to use HTML5 (Media Recorder API) where possible and falls back onto Flash where not. On Safari, this means Flash. Basically, I supply the library with a div where I want the recorder to appear and it inserts it there.\n\nHowever, some of my users were reporting confusion on Safari (the video recorder was not showing up) and I was able to reproduce this confusing situation. With Safari 12.0 on Mac OS 10.13.6 with Adobe Flash installed and enabled in Safari:\n\n\n\nwhen I navigate to the page with the video recorder, I expect to see a \"Click to use Flash\" button on the video recorder area. But, when I first load the page, the area is complete blank. Strangely, it appears that the button is indeed there, but just not showing:\n\n\nWhen I click on the area where the button should be, it responds (and prompts me to enable flash)\nWhen I open the Web Inspector tool, the button appears (you can also see the code for the Flash object here that gets inserted dynamically)\n\n\n\n\n\nWhen I simply resize the window, the button appears\n\n\n\n\nI don't use Safari as my regular browser, so it's not like I have a highly customized configuration.

"Opening and reading multiple netcdf files with RnetCDF",
"Using R, I am trying to open all the netcdf files I have in a single folder (e.g 20 files) read a single variable, and create a single data.frame combining the values from all files. I have been using RnetCDF to read netcdf files. For a single file, I read the variable with the following commands:\n\nlibrary('RNetCDF')\nnc = open.nc('file.nc')\nlw = var.get.nc(nc,'LWdown',start=c(414,315,1),count=c(1,1,240))\n\n\nwhere 414 & 315 are the longitude and latitude of the value I would like to extract and 240 is the number of timesteps.\n\nI have found this thread which explains how to open multiple files. Following it, I have managed to open the files using:\n\n filenames= list.files('/MY_FOLDER/',pattern='*.nc',full.names=TRUE)\n ldf = lapply(filenames,open.nc)\n\n\nbut now I'm stuck. I tried \n\n var1= lapply(ldf, var.get.nc(ldf,'LWdown',start=c(414,315,1),count=c(1,1,240)))\n\n\nbut it doesn't work. \nThe added complication is that every nc file has a different number of timestep. So I have 2 questions: \n\n1: How can I open all files, read the variable in each file and combine all values in a single data frame? \n2: How can I set the last dimension in count to vary for all files?"

"Animate words width with jQuery in infinite loop",
"I'm having an jQuery issue, which is making my life hard. \n\nSo what I have done until now if this JSBin\n\nOn what you can see, is that I am pretty close. What I need to achieve is to show words within a sentence, once one word is shown show the next one. Until a sentence has no words with a width of 0. Once that has happened the sentence hides, and the next sentence starts. Once all words in the last sentence are visible, everything starts over (infinite loop). But there has also to be the functionality of delays between words, and between sentences. I'm somehow not making progress right now with the code, so I thought I ask if someone had a similar issue, or if there is an plugin out there that could save my life.\n\nHow it should work is the following;\n\n\nThe words have to animate (as they are now)\nOnce one word appears, the next one is called\nOnce all words in one sentence have appeared, the sentence hides. Then the next word starts appearing which is in sentence two.\nSome words have to have a delay meaning they should start appearing after the delay given\nAlso I should be able to set intervals between sentences.\nOnce the second sentence is done, it should hide. And everything should start again.\n\n\nThanks a lot for any kind of assistance."

However, my exact same code with zero modification running on 3.2 is more than 10 times slower than when I run my code on 3.1.3\n\nIt took Python 3.2 six minutes to transfer binary content of a file to a physical device then receive and prints out the received data on screen, when the exact same scenario on same PC only takes 30 second to execute with Python 3.1.3.\n\nI developed my code from scratch with Python 3.1.2 and 20% of my code uses ctypes to perform transaction through windows driver with USB/PCI device, so I don't think this performance hit has anything to do with backward compatibility.

TabBarVC\n mapStatus = \"wentBack\"\n print(\"The value of mapStatus after seguing is \\(mapStatus)\")\n destinationVC.selectedIndex = 1\n\n }\n\n}\n\n\nMapView VC:\n\n override func viewDidAppear(_ animated: Bool) {\n // here if the mapStatus is not the correct value (the user never used the detail disclosure), the map will just snap onto the current location\n\n if mapStatus == \"wentBack\" {\n print(\"Do not update location\")\n\n // assuming appropriate code is placed here but I am not sure what it is\n\n\n } else {\n print(\"Updated Current Location\")\n let center = CLLocationCoordinate2D(latitude: self.lastLocation.coordinate.latitude, longitude: self.lastLocation.coordinate.longitude)\n let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))\n\n map.setRegion(region, animated: true)\n\n locationManager.delegate = self\n locationManager.desiredAccuracy = kCLLocationAccuracyBest\n if #available(iOS 8.0, *) {\n locationManager.requestAlwaysAuthorization()\n } else {\n // Fallback on earlier versions\n }\n let noLocation = CLLocationCoordinate2D()\n let viewRegion = MKCoordinateRegionMakeWithDistance(noLocation, 200, 200)\n map.setRegion(viewRegion, animated: false)\n\n }\n }"

"printing business cards - a kind of knapsack task",
"I am new to Prolog and I have some probably simple issue with a piece of code. This is a real world problem that arose last Friday and believe me this is not a CS Homework.\n\nWe want to print business cards and these can only be printed in blocks of 900 cards (100 sheets with 9 cards per sheet). The cards for anybody should not be distributed over several blocks. People ordered different amount of cards, E.G:\n\n% \"braucht\" is german and means \"needs\"\nbraucht(anton,400).\nbraucht(berta,200).\nbraucht(claudia,400).\nbraucht(dorothee,100).\nbraucht(edgar,200).\nbraucht(frank,400).\nbraucht(georg,100).\n\n\nI put together the following definition to find an appropriate block of 900 business cards:\n\nblock(0,[]).\nblock(N,[H|T]) :-\n braucht(H,Nh),\n% \\+(member(H,T)),\n D is N - Nh,\n D >= 0,\n block(D,T).\n\n\nThis produces a nice list of blocks of people whose cards fit together on a 900 cards block. But it stops working if I activate the commented line \"\\+member....\" and just gives me a \"false\". But I need to assure that nobody is getting more than once on that block. What am I doing wrong here?"

"Download script resulting in 404 page",
"I have put together a basic PHP script, that, when executed, should trigger a download of file stored on server. I took note from http://php.net/manual/en/function.readfile.php for using readfile function, and used identical code.\n\nThis used to work earlier, but now, suddenly, I've started getting 404 pages instead. Below is the snippet that I have :\n\nheader('Content-Description: File Transfer');\nheader('Content-Type: application/octet-stream');\nheader('Content-Disposition: attachment; filename='.basename($file));\nheader('Expires: 0');\nheader('Cache-Control: must-revalidate');\nheader('Pragma: public');\nheader('Content-Length: ' . filesize($serverPath));\nreadfile($serverPath);\nexit(0);\n\n\nWhen I insert debugging scripts in between, I'm able to see them, along with the weird data that readfile function receives from file, as files are PDF. But, on their own, this just gives me a 404 page with no error/warning anywhere.\n\nCan someone please point me to any issue that I'm having in code, or any thing that I can look into ? Any pointers would be very helpful, as I've spent almost all the day through forums and debugging, and still nowhere near to any kind of solution.\n\nEdit :\n\nBelow are the response headers received from server :\n\nDate: Tue, 21 Feb 2017 23:01:50 GMT\nServer: Apache/2.2.31 (Unix) mod_ssl/2.2.31 OpenSSL/1.0.1e-fips mod_bwlimited/1.4\nX-Powered-By: PHP/5.4.45\nExpires: Wed, 11 Jan 1984 05:00:00 GMT\nCache-Control: no-cache, must-revalidate, max-age=0\nPragma: no-cache\nContent-Disposition: attachment; filename=\"QM-1.pdf\"\nKeep-Alive: timeout=2, max=150\nConnection: Keep-Alive\nTransfer-Encoding: chunked\nContent-Type: application/octet-stream\n\n\nEdit 2 :\n\nSo, I tried the localhost approach, and the code indeed works perfectly fine in my local environment. PHP versions are same at both locations. Apart from that, any pointers where I should look at server level to find the cause behind this behavior ?"

"Escape SQL with bash",
"I'm working on importing data into MySQL from two business systems. I've written some bash scripts to compare the differences between the systems in order to only import the relevant parts. Now I need to construct SQL queries so I can load the data. My main problem is to escape single quotes, I've added the code part below that should escape it, but somehow that is only done sometimes, inconsistent. I don't get it...\n\nTEXT=${PART[1]/\\'/\\\\\\'}\n\n\nSo... Are there any better ways / programs I can pipe data through that escapes the data? The absolutely best solution would be to use MySQL's load data infile mixed with on duplicate update, but if I understand correct, that has not yet been implemented."
