"Height of cell taller than cell contents - view rendering issue",
"I have an odd problem I was hoping someone could perhaps explain. Searching yields nothing in this case.\n\nIf heightForRowAtIndexPath specifies a height which is taller than that of the contents drawn as a result of cellForRowAtIndexPath then upon scrolling, once the view refreshes its contents, it won't draw some of the cell contents that I've rendered (each row height is dynamic). However, if I reduce the row height somewhat, everything will be rendered correctly.\n\nIs there some documentation pertaining to this problem? Should heightForRowAtIndexPath always return the precise row height based on contents? For example, I just made the row heights rather large so I could always see the contents, but alas, cellForRowAtIndexPath wouldn't be called as many times as it should, and general rendering problems ensued.\n\nApologies for the fuzzy description, but perhaps those who have experienced the same problem could offer some insight.\n\nCheers."

"How to make R insert a '0' in place of missing values while reading a CSV?",
"We have a multi-column CSV file of the following format:\n\nid1,id2,id3,id4\n1,2,3,4\n,,3,4,6\n2,,3,4\n\n\nThese missing values are to be assumed as a '0' when reading the CSV column by column.

"Getting temperature difference between intervals",
"my question is more \"theoretical\" than practical - in other words, Im not really looking for a particular code for how to do something, but more like an advice about how to do it. Ive been thinking about it for some time but cannot come up with some feasible solution.\nSo basically, I have a MySQL database that saves weather information from my weather station. \n\nColumn one contains date and time of measurement (Datetime format field), then there is a whole range of various columns like temp, humidity etc. The one I am interested in now is the one with the temperature. The data is sorted by date and time ascending, meaning the most recent value is always inserted to the end. \n\nNow, what I want to do is using a PHP script, connect to the db and find temperature changes within a certain interval and then find the maximum. In other words, for example lets say I choose interval 3h. Then I would like to find the time, from all the values, where there was the most significant temperature change in those 3 h (or 5h, 1 day etc.). \n\nThe problem is that I dont really know how to do this. If I just get the values from the db, Im getting the values one by one, but I cant think of a way of getting a value that is lets say 3h from the current in the past. Then it would be easy, just subtracting them and get the date from the datetime field at that time, but how to get the values that are for example those 3 h apart (also, the problem is that it cannot just simply be a particular number of rows to the past as the intervals of data save are not regular and range between 5-10mins, so 3 h in the past could be various number of rows).\n\nAny ideas how this could be done? \n\nThx alot"

"Angular httpclient CORS request returns 404 error",
"I started a sample Angular application that runs on 127.0.0.1:4200 (PC A), I started a web browser at the same computer and everything works fine.\n\nIn the application, there is a heroService.ts that calls this.http.get etc to get the data from 127.0.0.1:4200.\n\nI then started another http server using nodejs express which provides some API services, the IP is 192.168.2.101:3000 (PC B). The api is perfectly fine because I can run it in any web browser and see the results (all in json). In nodejs express, I installed cors too and use app.use(cors()) to enable CORS support.\n\nThe following is where the problem is.\n\nI followed heroService.ts in PC A, and created apiService.ts, and use this.http.get(\"http://192.168.2.101:3000\").subscribe(_=>console.log(\"ok\")); to call the API at PC B (PC B should already have cors enabled).\n\nHowever, it seems that Angular running at browser cannot identify this address, and in browser's debug window, I can see 404 error, http://192.168.2.101:3000 cannot be found. Note that the same url http://192.168.2.101:3000 works perfectly in web browser directly.\n\nThe weird thing is that in the browser's (chrome and edge) network debug window, I could not see any request was sending out, there's no such request sent to the server. And at the nodejs's server side, I tried to log any connections and I could not see any too. It seemed to me that the web browser didn't send this http get out, and the angular library returned 404 directly.\n\nI tried to search the same error but could not find anything useful.\n\nI would guess that Angular's library will keep using the base url (127.0.0.1:4200) and will not parse http://192.168.2.101:3000 ? Is there a way to solve it?\n\nI hope I explained the problem clearly.\n\nThanks for help."

"Does iteratee I/O make sense in non-functional languages?",
"In Haskell, Iteratee based I/O seems very attractive. Iteratees are a composable, safe, fast ways of doing I/O inspired by the 'fold' a.k.a. 'reduce' function in functional languages. \nBasically, if you have a traversal the idea is to encapsulate the traversal state into a so-called \"enumerator\" who calls the \"iteratee\" which is in turn a function either returning a value or a request for more data along with a continuation for the enumerator to call. So only the enumerator knows the state of the traversal while the iteratee knows what to do with the data and builds values out of it. The nice thing about it is that iteratees are automatically composable, where output of one iteratee is fed to another to make a bigger one.\n\nSo, two questions: \n\n\nDoes the concept even make sence in other languages, like plain object oriented languages or is it only useful for overcoming the shortcomings of Haskell's lazy I/O?\nAre there any actual implementations for other languages, especially C# (as that is what my company uses)? (A google search turns up one mention of iteratees in Scala; well, I'm not that interested in Scala right now)."

I tried to follow the instructions here:\n\nhttps://github.com/web-push-libs/webpush-java/wiki/Usage-Example\n\nBut when BouncyCastle comes into play I'm getting the following exception:\n\njava.lang.NoSuchMethodError: org.bouncycastle.math.ec.ECCurve$Fp.<init>(Ljava/math/BigInteger;Ljava/math/BigInteger;Ljava/math/BigInteger;)V\n\n\nwhile processing nl.martijndwars.webpush.Utils.loadPublicKey(String) method.\n\n public static PublicKey loadPublicKey(String encodedPublicKey) throws NoSuchProviderException, NoSuchAlgorithmException, InvalidKeySpecException {\n byte[] decodedPublicKey = Base64Encoder.decode(encodedPublicKey);\n KeyFactory keyFactory = KeyFactory.getInstance(ALGORITHM, PROVIDER_NAME);\n ECParameterSpec parameterSpec = ECNamedCurveTable.getParameterSpec(CURVE);\n ECCurve curve = parameterSpec.getCurve();\n ECPoint point = curve.decodePoint(decodedPublicKey);\n ECPublicKeySpec pubSpec = new ECPublicKeySpec(point, parameterSpec);\n\n return keyFactory.generatePublic(pubSpec);\n}\n\n\nThe return-line then throws the exception.\nThe spi instance of the keyFactory is \"org.bouncycastle.jcajce.provider.asymmetric.ec.KeyFactorySpi$ECDH@5a15f280\" which also seems right...\n\nIm using the jar via maven. \"Luckily\" the parent web application brings BouncyCastle on it's own in Version 1.54. That's the dependency in the web apps pom.xml\n\n <dependency>\n <groupId>org.bouncycastle</groupId>\n <artifactId>bcprov-jdk15on</artifactId>\n <version>1.54</version>\n </dependency>\n\n\nWhich actually should exactly match the library's version (e.g. https://github.com/web-push-libs/webpush-java/blob/master/build.gradle)\n\nAnd when I call java.security.Security.getProviders() I'm getting a list that already contains 'BCFIPS version 1.01, BC version 1.54', which is because the parent application already provides it during runtime.\n\nWhen checking out the sources (http://javadox.com/org.bouncycastle/bcprov-jdk15on/1.53/org/bouncycastle/math/ec/ECCurve.Fp.html for instance) the constructor exists.\n\nI also tried to remove and add the BouncyCastleProvider from java.security.Security before executing the code.\n\nEDIT#1:\n\nI've made some progress in understanding the issue. I noticed that the web-server jre has a external library (bc-fips-1.0.1.jar) which seems to bring another implementation of org.bouncycastle.math.ec.ECCurve$Fp. This jar also seems to be the reason for the 'BCFIPS version 1.01' security provider.\n\nBy calling keyFactory.generatePublic(pubSpec) is seem that the KeyFactory somehow (classloading issue I guess) uses the other version ECCurve$Fp that really does not have the constructor from the error message.\n\nEDIT#2:\n\nI've debugged a while and could proof my theory. The WepAppClassloader picks the class from the lib-folder (which is the wrong one). Now I've tried somehow to preload the correct class for the right jar. But this does not seems to work.\n\nEDIT#3:\n\nThe final solution for me was to repackage the bouncy castle lib. Not nice but I had no ideas anymore."

"RMA MPI window access latency",
"I use Fortran (with gfortran) and MPI 2 (OpenMPI). Through MPI_Win_lock and MPI_Win_unlock together with put and get operations (in non-overlapping regions of memory) all processes update a variable on my master process, which is exposed through a window.\n\nIn a test case I have noticed, however, that the unlock operations from processes that are not the master do not return until the master has finished some task, in this case sleeping for some seconds.\n\nIf instead of sleeping the master, I make it wait for some seconds using a while loop and a timer, and in the meantime I make the master lock and unlock the window, everything goes much faster:\n\ncall start_time(time_left)\ndo while (time_left .gt. 0)\n call MPI_Win_lock(...)\n call MPI_Win_unlock(...)\n call update_time(time_left)\nend do\n\n\nHowever, in my real code the master performs operations just as the other processes, so it is impossible for it to continuously lock and unlock the window. Also, it seems to me rather wasteful. \n\nMy question is therefore how to decrease this latency?\n\nDo I really need to sprinkle my code with locks and unlocks for the master? Or is there another solution? Is this compiler / implementation dependent?"

"file: URIs and Slashes",
"An application I'm working on involves accessing files on network file shares, and we're using URIs to specify the files' locations.\n\nMy understanding of the file: URI is that they should take the form of file://+path. In the case of a Windows network share, this path looks something like \\\\servername\\dir\\file, so the resultant URI becomes file:////servername/dir/file.\n\nThis seems to be working great for Java's URI class, but the Win32 API seems to want a file://servername/dir/file style URI, which Java rejects because it \"has an authority component\".\n\nAm I understanding network-share URIs correctly? Is there another way to specify a path without Java complaining about the authority?\n\nEdit: We were hoping to be able to store paths as URIs, so as to make use of the scheme-part of the URI to specify other locations (e.g. file: versus other:).

"Creating a generalized resource map without using strings?",
"Let's assume I want to create an object that will hold some arbitrary data.\n\n// Pseudocode\nclass MyContainer {\n map<key, pair<void*, size>>;\n}\n\n\nThe key in this case also identifies the kind of data stored in the void* (e.g an image, a struct of some kind, maybe even a function).\n\nThe most general way to del with this is have the key be a string. Then you can put whatever on earth you want and then you can just read it. As a silly example, the key can just be:\n\n\"I am storing a png image and the source file was at location/assets/image.png and today is sunday\".\n\n\ni.e you can encode whatever you want. This is however slow. A much faster alternative is using enumerators and your keys are then IMAGE, HASHMAP, FUNCTION, THE_ANSWER_TO_LIFE...\n\nHowever that requires you know every single case you need to handle beforehand and create an enumerator for it manually (which is tedious and not very extensible).\n\nIs there a compromise that can be made? i.e something that uses only one key but is faster than strings and more extensible than enums?\n\nEdit:\nThe exact use case I am trying to use this for is as a generalized storage for rendering data. This includes images, vertex buffers, volumetric data, lighting information... Or any other conceivable thing you may need.\n\nThe only way I know to create \"absolute polymorphism\" (i.e represent literally any form of conceivable data) is to use void pointers and rely on algorithms to understand the data.\n\nExample:\n\nSay our key is a JSON string where the key of each element is the name of a field in a compact struct and the value is the offset in bytes.\n\nE.g \n\n {\n m_field1: 0,\n m_field2: 32,\n m_field3: 128,\n }\n\n\nThen to access any of the elements in the void* all you need to do is do symbol manipulation to get the number and then ptr + offset.\n\nYou can do the same with a set of unique identifiers (enums) and associated functions that get you the fields based on the identifier (hard coded approach).\n\nHopefully this makes the question less obscure."

I have the bottom linear layout set to anchor to the bottom of the screen, with a hardcoded height in dp. The larger LinearLayout is set to be above the bottom one.\n\nThis works as expected in portrait, but I cannot get the bottom (smaller) linearlayout to show up in landscape. Even if I set its height to a very high number. Both layouts look as expected in the Android Studio editor by the way.\n\nHere's the XML:\n\n<?xml version=\"1.0\" encoding=\"utf-8\"?>\n\n<RelativeLayout xmlns:android=\"http://schemas.android.com/apk/res/android\"\n android:layout_width=\"match_parent\"\n android:layout_height=\"match_parent\"\n android:layout_weight=\"1\"\n android:background=\"#ff1b284b\"\n android:orientation=\"vertical\">\n\n\n <LinearLayout\n android:orientation=\"horizontal\"\n android:layout_width=\"match_parent\"\n android:layout_height=\"wrap_content\"\n android:layout_above=\"@+id/plusZoomMinusButtons\">\n\n -- Removed inner views --\n\n </LinearLayout>\n\n <LinearLayout\n android:id=\"@+id/plusZoomMinusButtons\"\n android:layout_width=\"match_parent\"\n android:layout_height=\"40dp\"\n android:gravity=\"top\"\n android:orientation=\"horizontal\"\n\n android:layout_alignParentBottom=\"true\">\n\n -- Removed inner views --\n\n </LinearLayout>\n</RelativeLayout>\n\n\nedit: The problem wasn't even with the layout, I found a piece of code elsewhere in the program that messed with the layout, but only in landscape :|"

"Worst case scenario in Linear Programming with variable constraints",
"I have a linear optimization problem: \n\nminimize c^T x\nwhere A x = b\n\n\nBut I want to find the 'worst case scenario' when b is flexible (m_i < b_i < M_i). A naive approach would be applying a non-linear optimization to the linear one:\n\nmaximize [minimize c^T x where A x = b] where b_min < b < b_max\n\n\nIs there any better way to do this?\n\nMaybe a real example: \nThe famous diet problem, where we look for a cheapest combination of foods that satisfy all nutritional requirements. But as nutritional requirements aren't completely set (and depend on person and his daily activity), constraints are flexible and we want to find a worst case scenario - what would be most expensive set of constraints - if food combination is optimized.\n\nhttps://en.wikipedia.org/wiki/Bilevel_optimization - this is basically what I need, I'll try the linked optimizer and post the result."

"How convert spectral image elements to RGB in R language?",
"I'm planning to convert multispectral images to rgb based images- (RGB values of visible spectrum)\n\nBasically, I'm reading png spectral image by \"readPNG\" function in R. \n\nSo, I have 2 dimensions 512X512 matrix. then according to the link above I write function that return values for R,G,B.\n\nNow, my question is how I can apply this RGB to the my image to convert to rgb?\n\nSome part of my code: \n\nimg <-readPNG(\"sample_img.png\") # 512 X 512 Matrix \n\n# after calculate R,G,B \nr = 1\ng = 0.892\nb = 0\n\nel1 <- img * r \nel2 <- img * g\nel3 <- img * b\n\ncol <- as.matrix(el1, el2, el3)\nplot (1:512 , type=\"n\" ) \nrasterImage(col, 1, 1, 512, 512)\n\n\nI'm doing code like above , and still couldn't convert to get color image.\n\n(more information about spectral: multispectral )"

"javascript on change needs refresh",
"I'm trying to make a textbox, with a counter to show how many signs you have left (pure for user interface purposes, not the actual validation). \n\nI tried to use this code:\n\nfunction checkRemainingChars () {\n\n var maxChars = 500;\n var text = document.getElementById('textArea').value;\n console.log(text);\n var usedChars = text.length;\n var remainingChars = maxChars - usedChars;\n var message = \"<p>\" + remainingChars + \"out of \" + maxChars + \" characters remaining </p>\";\n console.log(message);\n $('#remaining').append(message);\n}\n\n\n$(document).ready( function () {\n\n $('#textArea').on('change',checkRemainingChars());\n\n});\n\n\nwhere #textArea is the textarea where the user puts his text, and #remaining is an aside with the message how much signs he has remaining.\n\nthis only works when the page loads/refreshes. then I tried to add something simple, to eliminate possible mistakes in my code:\n\n$(document).ready( function () {\n\n $('#textArea').on(\"change\",alert(1));\n\n});\n\n\nbut even here I only get the alert when I refresh the page. What do I have to do to make the text update as soon as the user types something?"

"What type of arguments does [NSString stringWithFormat] take?",
"I know that the method stringWithFormat is usually used as follows:\n\n[NSString stringWithFormat: @\"%@ %@\", arg1, arg2];\n\n\nMy question is, what exactly is the type of the last argument of this method (the one with ... in the specs).\n\nI want to be able to do something like the following:\n\nNSArray *array = [NSArray arrayWithObjects: @\"Hi\", @\"Bob\"];\n[NSString stringWithFormat: @\"%@ %@\", array]\n\n\nAs you can see one datastructure array is holding all of the arguments. Unfortunately, this doesn't work. Is there a way to do this so that I don't have to explicitly list out all of my arguments in the stringWithFormat method?"
