"graphLookup StartWith Object instead of Array",
"today a i read about the $graphLookup feature and i was totaly impressed about this (for me) new feature.\nCurrently i solve these type of problems with eval and now i gonna transfer these functions to $graphLookup.\n\nOne of these functions is \"getAllSubFolders()\". And now i got in some troubles, because my\nconnectFromField is a object, rather than being an array (as in the mongoDB documentation examples).\n\nTo unterstand this better:\n\nFolder documents are structured like this:\n\n{\n \"_id\" : ObjectId(\"58286a66d43ee415567ab4c8\"),\n \"Children\" : {\n \"File_58286ce0d43ee415567ab4e5\" : \"58286ce0d43ee415567ab4e5\",\n \"Folder_5829d284d43ee41fa74f7e50\" : \"5829d284d43ee41fa74f7e50\",\n },\n \"UserID\": \"1\"\n ...\n}\n\n\nNow as i mentioned, i need a aggregation pipeline (with $graphLookup?) which will give me all subfolders back.\nAny ideas how to solve this?\n\nTo be more specific: My current problem is startWith. I need something like:\n\ndb.folders.aggregate( [\n{ $match : { \"UserID\" : \"1\" } },\n {\n $graphLookup: {\n from: \"folders\",\n startWith: \"getObjectValues($Children)\", //returns an array with the object values\n connectFromField: \"getObjectValues($Children)\", // not sure about this\n connectToField: \"_id\",\n as: \"sub_folders\"\n }\n }\n]);\n\n\nPS: Nice but not needed would be if we search only for Children which has Folder_ in the key. I don't know if there's a possibility to filter it.\n\nOk, so our origin document looks like this:\n{ \n \"_id\" : ObjectId(\"581bae37d43ee401131d8293\"), \n \"UserID\" : \"37\", \n \"Children\" : {\n \"File_581bb4abd43ee401131d82a0\" : \"581bb4abd43ee401131d82a0\", \n \"Folder_581bc233d43ee401131d82b8\" : \"581bc233d43ee401131d82b8\", \n ...\n }\n}\nNow we need an query that return this document:\n{ \n \"_id\" : ObjectId(\"581bc233d43ee401131d82b8\"), \n \"Children\" : {\n \"Folder_5826034c0c0a1c005d64f921\" : \"5826034c0c0a1c005d64f921\"\n }, \n}\nbut also the child folder with the id 5826034c0c0a1c005d64f921.\n{ \n \"_id\" : ObjectId(\"5826034c0c0a1c005d64f921\"), \n \"Children\" : {\n \"Folder_593032743f54cc0078025802\" : \"593032743f54cc0078025802\"\n }\n}\n... recursive, down to the last element (until the object children contains no more folders)\n\n\nOverall the result should like this:\n\n{\n \"_id\" : ObjectId(\"581bc233d43ee401131d82b8\"),\n \"Children\" : {\n \"Folder_5826034c0c0a1c005d64f921\" : \"5826034c0c0a1c005d64f921\"\n }, \n},\n{\n \"_id\" : ObjectId(\"5826034c0c0a1c005d64f921\"),\n \"Children\" : {\n \"Folder_593032743f54cc0078025802\" : \"593032743f54cc0078025802\"\n }\n},"

"Cassandra insert preparedStatement or mapper?",

Question is : what has best performance: using the mapper (annotating our object 'JPA' style) or using a prepared statement, which will only be prepared once and then bind for every insert. \nI read here that the mapper does an implicit prepared statement in the background so performance should not differ. But I don't understand where he should keep that prepared statement? Or is it done for every insert, which would take away the advantage of doing a prepared statement.

"On building a head tracker for your head mounted display using your android mobile phone",
"My goal is to code a headtracker for my head mounted display using my android phone. The movement is transferred to mouse movement, which in turn is used inside pc games. I want to mount my android phone to the back of the head-tracker, so it will be fixed to the back of my head. The y-axis is facing upwards, the x-axis is facing to the right when looking straight ahead, that means when you look at my back head, you see the mobile phone display.\n\n\n\nDue to mechanics of this setup there is an angle between the y-axis and the gravity-axis, so the mobile phone is tilted slightly away from the back of the head when looking straight forward. Also it is slightly rotated around the z-axis and might be rotating while moving around the z-axis within an angle of about 5 to 10°.\n\nMy phone does not have a gyroscope. I used \n\npublic void onSensorChanged(SensorEvent event)\n{\n // alpha is calculated as t / (t + dT)\n // with t, the low-pass filter's time-constant\n // and dT, the event delivery rate\n\n final float alpha = 0.8;\n\n gravity[0] = alpha * gravity[0] + (1 - alpha) * event.values[0];\n gravity[1] = alpha * gravity[1] + (1 - alpha) * event.values[1];\n gravity[2] = alpha * gravity[2] + (1 - alpha) * event.values[2];\n\n linear_acceleration[0] = event.values[0] - gravity[0];\n linear_acceleration[1] = event.values[1] - gravity[1];\n linear_acceleration[2] = event.values[2] - gravity[2];\n}\n\n\nwhich works better than just using raw data from the accelerometer. I just used 0.8 as alpha, do I need to adjust it according to t / (t + dT)? So how to get t and dT then?\n\nUsing this setup, tilting the head up and down works - with some refinement here and there - well. \n\nBut moving left and right turns out to be an issue. Also moving diagonal from left-down to right-up and mirrored. Or moving in circles.\n\nComing from the basic mathematics and not my error description, which code do you suggest to make this work?"

"I'm stuck on a Java coding assignment. I'm supposed to create three methods (askInfo, copyInfo, and setArray) for an existing program that lets the user input numbers into an array, and then organizes and prints that array.

CopyInfo copies the values into a new array with a length of the returned amount of numbers, and setArray sorts the numbers. \n\nMy problem is that, according to the assignment, askInfo is only supposed to return the amount of inputted numbers. Thus it leaves the values of the array printed with it inside the method, making copyInfo unable to retrieve those values and copy them into the second array. How would you suggest I get past this problem without the ability to edit the main method? \n\nMain method:\n\n int[] tempArray = new int[100];\n System.out.println(\"Type in numbers. Type zero to quit.\");\n int amountOfNumbers = askInfo(tempArray);\n\n int[] realArray = new int[amountOfNumbers];\n copyInfo(realArray, tempArray);\n\n setArray(realArray);\n\n printArray(realArray);\n\n\nMy code:\n\npublic static int askInfo (int[] tempArray) { //asks for numbers and assigns them to tempArray, returns the length of realArray\n int count = 0;\n Scanner reader = new Scanner(System.in);\n for (int i =0;i<tempArray.length;i++){\n System.out.print((i+1)+\". number: \");\n tempArray[i] = reader.nextInt();\n count++;\n if (tempArray[i] == 0) //stops asking for values if user inputs 0\n return count;\n }\n return count;\n }\n\npublic static int[] copyInfo (int[] realArray, int[] tempArray) { //copies tempArray's values to realArray\n for (int i=0; i<realArray.length;i++){\n realArray[i] = tempArray[i];\n }\n return realArray;\n}\n\npublic static int[] setArray (int[] realArray) { //sorts realArray from largest value to smallest\n for (int i=0;i<realArray.length;i++){\n for (int j=i+1;j<realArray.length;j++){\n if (realArray[i]<realArray[j]){\n int tmp = realArray[i];\n realArray[i] = realArray[j];\n realArray[j] = tmp;\n }\n }\n }\n return realArray; \n}\n\n\nRight now the program does compile, but the values of the arrays realArray and tempArray get outside of the askInfo method are null.

I also selected \"Compress the contents of the JAR file\".\nIn the next screen I checked \"Export class file with compile errors\" and \"Export class file with compile warnings\" \n\n\nI heard the right way to obtain an exe file is to convert a .jar into .exe so I used the \"Launch4j\" application with the .jar obtained previously:\n\n\nIn the \"Basic\" panel: specified OUTPUT FILE: C:\\Users\\jerry\\Documents\\Sw3.exe and the JAR file: C:\\Users\\jerry\\Documents\\Sw3.jar. \nProcess priority NORMAL\nHeader type: GUI\nMIN JRE Version: 1.0.0 \nI pressed the \"wheel\" and chose Project.xml and got a succesful confirmation message.\n\n\nI have JRE installed, so the .exe should work, but it doesn't work.

"Falling into a catch clause in CIL",

Now in memory we are executing same method, does this needs any kind of locking. In my view No, I have tested, but I am not sure in theory why, wouldn't different threads mess up with each other's parameter value, in my implementation it doesn't seems the case.\n\nOnly thing I cannot guarantee, is which thread access and returns first as that would not be in the order, but if I do not care about it, is this implementation correct.\n\nPlease note, this is an attempt to describe the issue in a stand alone manner, I have similar implementation as part of a complex project.\n\nAny suggestions / pointers would be great.

"Time event was sent?",
"In JavaFx, is there any reliable way to know at what time an event was posted ? \n\nAnd since this question is too short for stackoverflow, I elaborate somwhat. In asychronous event systems, which I believe javafx is, events get posted on a queue and then at a later stage handled. The time between posting and handling is unknown, allthough it is estimated to be small. Nevertheless, there are no guarantees that this time is indeed small. Therefor I would really like to know whether it is possible to know the time of posting the event. E.g: when the user actually clicked the button (as opposed to when the program looks at it)."

However, the certificates in the Local Machine store are placed correctly. I'm not sure why that is. So basically, the private key is not being placed in the store properly so the signature fails.

"XSLT: How to ensure that a multi-mode identity template does not override all imported match templates?",
"I am writing an XSLT transformation that should largely leave the structure of the input XML unchanged, but add a few attributes and change a few element names.\n\nTo achieve this, I have an identity template, which ensures that all nodes which are not matched by another template (with a higher priority) will be retained as-is.\n\n\n\n<!-- Identity template: leaves in place nodes not matched by a more specific template. -->\n<xsl:template mode=\"#all\" priority=\"2\" match=\"@*|node()\">\n <xsl:copy>\n <xsl:apply-templates mode=\"#current\" select=\"@*|node()\"/>\n </xsl:copy>\n</xsl:template>\n\n\nI am performing a multipass transformation of the input document, with each pass using a different mode. To avoid duplication of the identity template across all these modes, I have therefore set its mode to #all.\n\nThe issue arises when I want to import a few templates with match attributes I want to be applied in this stylesheet. The algorithm XSLT uses to decide which template with a match attribute to apply when calling <xsl:apply-templates> is:\n\n\nmode\nmatch\nimport precedence\npriority\n(declaration order)\n\n\nSince the identity template has mode=\"#all\" and match=\"@*|node()\", it will match all modes and all node types. Then, the property next in line to determine which template will be applied is the template's import precedence.\nHowever, since imported templates always have a lower import precedence than local templates, this identity template will always trump any imported template, thus rendering importing templates with match attributes a futile endeavour.\n\nMy question is: what is the most suitable way around this? I.e. How to ensure that a multi-mode identity template does not override all imported match templates?\n\nI have two proposed solutions, but neither are entirely satisfactory to me:\n\n\nchange the value of the identity template's mode attribute to explicitly list all modes used, e.g. mode=\"#default mode1 mode2 mode3\". I find this problematic in the sense that I now need to remember to update this attribute value every time I alter the modes in use (e.g. add or rename a mode). It would also involve keeping track of all the modes used in the imported stylesheet, or alternatively another identity template in the imported stylesheet for those modes.\nuse <xsl:include> instead of <xsl:import> to fetch the relevant external templates. This would probably work in my specific case, but I don't like it as a general solution, as these XSLT elements have different semantics and work in different ways, and this is likely not what I want as my web of XSLT stylesheets grows in complexity."

"I am unsure if CMFCEditBrowseCtrl is really designed for this, but I want to employ it as a way to let the user choose a file from a dialog, rather than manually have a button whose handler creates a CFileDialog.\n\nThe issue I'm having is I want to call an event handler when a file is chosen, but I don't know what event to catch. I tried to use ON_EN_CHANGE but this crashed my program - I clicked the button, and before the open-files window appeared, I got I got a weird popup \"invalid file choice ??????????\" (or similar, I don't have the code here) and when I clicked OK the application ended.\n\nIs this a valid use of the control, and if so what would a minimal sample look like?"
