"Is it possible to select a java.awt.Frame with Robot Framework in conjunction with SwingLibrary?",
"I've been testing a Java Swing based application with Robot Framework in conjunction with Swing Library for some time. I'm stuck in one of the test cases because the Select Window keyword does not find the desired window on the screen, although it is visible. \n\nHere's a code snippet showing the relevant keywords of this test case:\n\n...\nSelect Window Main Window\nPush Button Add Person\nList Windows\nSelect Window Person Manager\n\n\nThe first three lines are working fine, but the Select Window Person Manager fails with the following rather short message:\n\n14:24:40 FAIL Frame with name or title 'Person Manager'\n\n\nAfter debugging the application under test I identified the source of the problem: the window not being found is instance of java.awt.Frame.\n\nInterestingly, it is listed by List Windows.\n\nIs there a known workaround or existing extension of Swing Library to be able to focus on a java.awt.Frame?"

"Find lines that have partial matches",

Here is a small example portion of the text file.\n\nexample text file \n\n 1002IPU3...\n POIPIPU2...\n 1435IPU1...\n 1812IPU3...\n BFTOIPD3...\n 1435IPD2...\n\n\nAs you can see, there are two lines that contain 1435 within this text file, which coincides with a specific instrument. However these lines are not identical. The program I'm using can not do its calculation if there are duplicates of the same station (ie, there are two 1435* stations). I need to find a way to search through my text files and identify if there are any duplicates of the partial strings that represent the stations within the file so that I can delete one or both of the duplicates. If I could have BASH script output the number of the lines containing the duplicates and what the duplicates lines say, that would be appreciated. I think there might be an easy way to do this, but I haven't been able to find any examples of this. Your help is appreciated."

"In Python, changing inherited behavior without rewriting the parent class",
"In Python, I have a class ParentClass. It defines method ParentClass.process(), among the others. ParentClass is inherited by two child classes: ChildA and ChildB. This is a part of the system which goes as a pip wheel. The user should not be able to change the code of the package.\n\nDuring the execution, the system creates objects of ChildA and ChildB.\n\nNow, I want to give the user of the system ability to change the behavior of .process() method for objects of both ChildA and ChildB. \n\nObviously, she can do that by redefining ChildA.process() and ChildB.process() but that would be copying of identical behavior twice and overall seems like a very odd approach.\n\nThe user could possible inherit her own class from ParentClass and redefine .process() there but that means I need somehow dynamically tell ChildA and ChildB what to inherit. \n\nAlso, all classes (ParentClass, ChildA and ChildB) have other methods, apart from .process(), which need to be retained without changes.\n\nPlease help me figuring out the most convenient for the user (and the most \"pythonic\", probably) way of solving this."

"{kdenlive} How do I join two adjacent clips into one in kdenlive?",
"Suppose I made a mistake: I cut a clip into two using the scissor tool, and I did it off by a few frames. I want to undo the mistake and join the clips together again and split them at the right frame.\n\nPlease assume the case where a simple Undo won't work due to how broken the undo functionality is in kdenlive.\n\nI have searched high and low, and found lots of answers that boil down to \"you don't really need this, because for each and every thing you could possibly need it for, you can achieve the same goal without joining the clips together\". Yes, it's possible, but its cumbersome and workaroundy and every subsequent operation on the affected time range requires twice as many clicks and twice as many attention registers.\n\nI will accept an authoritative negative answer to the effect of \"this is just not possible, full stop\", coming from an expert who knows kdenlive through and through. Knowledge of impossibility is valuable. I will then know that I must be more careful to avoid the problem. For example, whenever I split a clip, I could back the uncut version on an unused track: a manually maintained undo stack. STILL better than constantly grouping and ungrouping and having to remember what must be grouped and what not."

"How is this Checksum calculated?",
"Good day friends.\nI'm using Qt C++ and I've ran into a issue calculating a checksum for a serial communication protocol. I'm very new to serial programming and this is a little above my knowledge atm\nPer their documentation.\nCommunication format\n\nHead Address CID Datalength Data Check Tail\n\n0x7E 0x01~0x0e 0x01 - - checksum 0x0D \n\nthe head never changes, the address can change, the CID is a command\nI don't understand how the data length is to be calculated\nthe checksum I'm not clear on how they calculate it. Are they taking the first 5 bytes then calculating the checksum then adding the tail ? or only the "command" which to me is the CID byte. but that doesn't make sense.\nThe function they use to calculate the checksum\nbyte check(byte* buf, byte len)\n{\n byte i, chk= 0;\n int sum = 0;\n for(i = 0; i < len; i++)\n {\n chk ^= buf[i];\n sum += buf[i];\n }\n return ((chk^sum)&0xFF);\n}\n\nWhich I Wrote in Qt as\nunsigned char MainWindow::Checksum_Check(char* buf, char len)\n{\n unsigned char i, chk = 0;\n int sum = 0;\n for(i = 0; i < len; i++)\n {\n chk ^= buf[i];\n sum += buf[i];\n }\n return ((chk^sum)&0xFF);\n}\n\nSo sending a hexidecimal command using QBytearray\n QByteArray Chunk("\\x7E\\x01\\x01\\x00");\n\n char *TestStr = Chunk.data();\n unsigned char Checksum = Checksum_Check(TestStr, Chunk.length()); // tried sizeof(char) even tried sizeof(Chunk.size())\n\n const char cart[] = {'\\x7E', '\\x01', '\\x01', '\\x00', checksum, '\\x0D'};\n QByteArray ba4(QByteArray::fromRawData(cart, 6));\n SerialPort->write(ba4.toHex()); // Tried write(ba4); as well. \n SerialPort->waitForBytesWritten(1000);\n\nWhat i get in qDebug() is\nChecksum "FE"\nCommand "7E010100FE0D"\nWhich looks correct but the device ignores the request.\nMy question is. Is the checksum calculated correctly by me or am I missing something crucial ?\nAny advice or help would be most welcome as I am stuck.\nIve checked it with one of their example commands:\n7E 01 F2 02 FF FF FE 0D\n\nwhich if i do this:\nQByteArray Chunk("\\x7E\\x01\\xF2\\x02\\xFF\\xFF");\n\nchar *TestStr = Chunk.data();\nunsigned char Checksum = Checksum_Check(TestStr, Chunk.length());\n\nconst char cart[] = {'\\x7E', '\\x01', '\\xF2', '\\x02','\\xFF', '\\xFF', Checksum, '\\x0D'};\nQByteArray ba4(QByteArray::fromRawData(cart, 8));\n\nQString hexvalue;\nhexvalue = QString("%1").arg(CRC, 0, 16, QLatin1Char( '0' ));\n\nqDebug() << "Checksum " << hexvalue.toUpper();\nqDebug() << "Command " << ba4.toHex().toUpper();\n\nSerialPort->write(ba4.toHex());\n\nGives me\nChecksum "FE"\nCommand "7E01F202FFFFFE0D"\n\nwhich is correct. By the looks of things. But the device still doesn't respond\nSo I just wanna verify that the checksum is in fact generated correctly.\nAlso in the documentation is an example\nPC software Command:\nbuf[0] = 0x7E; //head\nbuf[1] = 0x01; //addr\nbuf[2] = 0x01; //CID\nbuf[3] = 0x00; //data length\nbuf[4] = CHK; //Check code\nbuf[5] = 0x0D; //tail\n\nAnd here is another question. How can a checksum buf[4] be generated while the ByteArray is still being constructed. It doesn't make sense to me at this point. I dont know/understand which bytes they use for the checksum\nAnyone? thanks"

"ASP.NET MVC: relationship between models and MembershipUsers",
"I have a model, Docs, with a guid column, author_id, which should reference a MembershipUser.\n\nI'm using the standard MembershipProvider (I only changed the db name), and of course I haven't a model for MembershipUsers.\n\nI can easily define some methods in class Docs to get MembershipUser for a Doc and all Docs for a MembershipUser, but some things are tricky (listing users, show how many docs each user has); furthermore, I feel I'm using MVC in an odd way: it seems to me that it would be easier if I had a MembershipUsers model...\n\nHow can I implement this relationship? Should I implement a model for MembershipUsers?\n\nthanks\n\nupdate: I realize I wasn't clear at all.\n\nSay I want to list all my users and their docs.\nOne way to do this is:\n\nViewModel model = new ViewModel()\n{\n Users = from MembershipUser user in Membership.GetAllUsers(page, pagesize, out totalusers)\n select new UserWithDocs\n {\n User = user,\n Docs = context.Docs.Where(c => c.author_id == (Guid) user.ProviderUserKey)\n },\n UsersCount = totalusers\n};\n\n\nThis works, but generates one separate query for each user.\n\nI could get an array of users' guids and then query for Docs where author_id IN list_of_guids, but then I should manually associate each doc to its author.\n\nWhat is a better solution?"

"Symfony 3 - Images not updating instantly",
"Currently working on a Symfony 3 application. I created a service that lets users upload an image, then choose a crop section, and finally saves the avatar with a specific height and width. Avatars are saved in the /web/img/uploads/avatar/ folder. I'm using the user id to name the file. So the user with the id 13 will have his avatar saved at /web/img/uploads/avatar/13.png.\n\nMy problem is that, when an user updates his avatar, the file is correctly replaced in the folder, but on the actual website the avatar displayed remains the old one for a while.\nIn dev environment this takes something like a few minutes before the new avatar replaces the old one. Even if I go to the avatar url (localhost/app_dev.php/img/uploads/avatar/xxx.png) I still see the old avatar for a while before it's eventually replaced by the new one. Tho, the avatar in the filesystem is instantly replaced, as expected.\n\nI figured this might come from the cache. I tried searching for solutions on google but all I found was related to the LiipImagineBundle and its cache manager, but I'm not using this bundle...\n\nI tried deleting the old avatar if it exists after figuring out its name, and before actually croping and saving the image. As follows.\n\nif(file_exists($dst)) {\n unlink($dst);\n}\n\n\nBut it doesn't work. At all.\n\nAny ideas?"

"Calculating Floating Point Powers (PHP/BCMath)",
"I'm writing a wrapper for the bcmath extension, and bug #10116 regarding bcpow() is particularly annoying -- it casts the $right_operand ($exp) to an (native PHP, not arbitrary length) integer, so when you try to calculate the square root (or any other root higher than 1) of a number you always end up with 1 instead of the correct result.\n\nI started searching for algorithms that would allow me to calculate the nth root of a number and I found this answer which looks pretty solid, I actually expanded the formula using WolframAlpha and I was able to improve it's speed by about 5% while keeping the accuracy of the results.\n\nHere is a pure PHP implementation mimicking my BCMath implementation and its limitations:\n\nfunction _pow($n, $exp)\n{\n $result = pow($n, intval($exp)); // bcmath casts $exp to (int)\n\n if (fmod($exp, 1) > 0) // does $exp have a fracional part higher than 0?\n {\n $exp = 1 / fmod($exp, 1); // convert the modulo into a root (2.5 -> 1 / 0.5 = 2)\n\n $x = 1;\n $y = (($n * _pow($x, 1 - $exp)) / $exp) - ($x / $exp) + $x;\n\n do\n {\n $x = $y;\n $y = (($n * _pow($x, 1 - $exp)) / $exp) - ($x / $exp) + $x;\n } while ($x > $y);\n\n return $result * $x; // 4^2.5 = 4^2 * 4^0.5 = 16 * 2 = 32\n }\n\n return $result;\n}\n\n\nThe above seems to work great except when 1 / fmod($exp, 1) doesn't yield an integer. For example, if $exp is 0.123456, its inverse will be 8.10005 and the outcome of pow() and _pow() will be a bit different (demo):\n\n\npow(2, 0.123456) = 1.0893412745953\n_pow(2, 0.123456) = 1.0905077326653\n_pow(2, 1 / 8) = _pow(2, 0.125) = 1.0905077326653\n\n\nHow can I achieve the same level of accuracy using \"manual\" exponential calculations?"

Any suggestions?\n\nUPDATE: I mean doing it at the HTML source code level rather than in the run time.\n\nUPDATE2: The task actually means replacing every occurrence of the name=\"my-field\" pattern (where there can be anything reasonable in place of my-field (but will contain the minus usually, so supporting just letters is not enough)) with name=\"my-field\" id=\"my-field\".

"How to change ACE TypeGuessRows Registry Value for Access 2007 to Determine Field Data Type Properly When Importing From Excel File Using VBA",
"I have an Access database that imports data from an external Excel spreadsheet that contains a column of data called Date Delivered. While most data in this column is actually a date type, sometimes entries like 4/5/15,5/1/15 will be made to indicate two delivery dates. \n\nThis trips up Access when importing the data using: \n\nDoCmd.TransferSpreadsheet acImport, 5, \"Delivery Data\", \"\\\\File\\Path.xlsx\", True \n\n\nThis causes it to make the column the date type rather than a string which drops any value from those fields which is problematic. I found what appeared to be a helpful solution here that suggested changing the TypeGuessRows registry value to 0 to make Jet look at all rows when determining the field data type. \n\nI created and changed the registry value using the following code:\n\nDim RegLoc As String\nDim myWS As Object\n\n'Writes registry value to make Jet check all rows (0) not just first 25 (Default value = 8) to determine type\nRegLoc = \"HKEY_CURRENT_USER\\SOFTWARE\\Microsoft\\Jet\\4.0\\Engines\\Excel\\TypeGuessRows\"\nSet myWS = CreateObject(\"WScript.Shell\")\nmyWS.RegWrite RegLoc, 0, \"REG_DWORD\"\n\n\nUnfortunately this did not seem to work as the problem persisted after changing the value and restarting Access and Excel. \n\nIs there a separate registry value for Access vs Excel Jet engine or does this simply not do what I think it should?\n\nEdit:\n\nLooks like for Excel 2007 and newer (I am using 2007), the registry value should be: \n\nHKEY_CURRENT_USER\\Software\\Microsoft\\Office\\12.0\\Access Connectivity Engine\\Engines\\Excel\\TypeGuessRows\n\n\nHowever it still isn't working.\n\nEdit 2:\n\nHere is the code to do what @PractLogical suggested:\n\nSQL = \"CREATE TABLE [Delivery Data Import] ([F1] TEXT, [F2] TEXT,[F3] TEXT, ...)\"\nCurrentDb.Execute SQL\n\nDoCmd.TransferSpreadsheet acImport, 5, \"Delivery Data Import\", \"\\\\File\\Path.xlsx\", False\n\nSQL = \"INSERT INTO [Delivery Data] ( Buyer, [PO #], [Receipt Status],...) SELECT [Delivery Data Import].F1, [Delivery Data Import].F2, [Delivery Data Import].F3,...] WHERE (Get rid of headers);\"\nCurrentDb.Execute SQL\n\n\nI am still looking for a one and done solution for all imports via registry key if it exists (knowing it doesn't exist would also be useful)."

"Current time in IO monad",
"If I have the following, for example:\n\nimport Data.Time.Clock.POSIX\n\nt = getPOSIXTIME\n\n\nThen t :: IO POSIXTime. That means it is in the IO monad, this much I understand. Is there any way to get the value out of the monad to use in other functions in the program? I don't want to output the value to the terminal.\n\nI apologise for such a newbie question, but the more monad tutorials I read the less I understand any of it. This is essentially more a question about monads than specifically about time."

"Why Pylint is too slow while pep8 just takes a second to check the same code?",
"I do not understand why pylint takes about 5 minutes to check my code, where pep8 takes only 1 sec. \n\nI use Mac and I have pylint 1.8.4 installed through conda install -c conda-forge pylint. Pylint is very slow either I use Terminal or the Spyder editor. I tried creating a config file .pylintrc but it didn't make a difference to the speed. \n\nHow can I accelerate the Pylint speed? Thank you."

"non-jar SVN dependency management",
"Hypothetically there were two software companies, A & B. Both companies have about a couple of hundred Eclipse projects. Both have a few application end-products. Each end-product project has a dependency different from the others.\n\nA relies on maven for dependency management. It practices code freezing and therefore decouples projects from each other and hence is able to mavenize dependencies.\n\nB relies on Eclipse Subversive plugin. For any particular end-product project, all projects it depends on will be checked out of SVN and included in the Eclipse project build path. If a project has dependencies on 50 projects, all 50 projects will be subject to source code modification and that is why they do not use Maven.\n\nThe two companies merged into AB. The desire is to have a maven like dependency management that would also work on SVN repositories. That is, the hypothetical POM should be able to specify either jar dependency (company A style) or SVN source-code dependency (company B style). If the dependency is a jar, it should pull the dependency from the repository into the developer's workstation's maven cache. If the dependency is source code in SVN, it should check it out into the SVN working directory.\n\nHow should company AB proceed with their vision unifying the two build attitudes, technologically? I specify \"technologically\" to avert answers that would deal with micromanaging or modifying the philosophical attitudes of developers of the merged company.\n\nWould Gradle be of any help? If so, how and why? What other alternatives?"

"How to replace strings in a list by numbers based on their endings?",
"Assume I have a list like this \n\nmyList = ['A_x1', 'B_x2', 'C_x1', 'D_x3', 'E_x1']\n\n\nand a dictionary like this\n\nmyDict = {'_x1': 0.1, '_x2': 0.5, '_x3': 0.7}\n\n\nNow I would like to replace all strings in myList by the value stored in myDict associated to the ending of this string. I can of course achieve that by using the following:\n\nfor ind, l in enumerate(myList):\n for k in myDict.iterkeys():\n if l.endswith(k):\n myList[ind] = myDict[k]\n\n\nwhich gives me the desired output:\n\n[0.1, 0.5, 0.1, 0.7, 0.1].\n\n\nBut how could this be done using e.g. map or anything else more efficient?"
