"Is the data in a memory-mapped file guaranteed to flush sequentially?",
"I'm trying to implement a file storage mechanism which holds a number of variably-sized records in a single file with the guarantee that the set of records will always be recoverable into a consistent state, even if the system failed at a hardware level.\n\nSo far, every scheme I've come up with pivots on writing data sequentially. Some piece of data would be appended to the end of each record which confirms that the write succeeded. However, if the data is not necessarily written to the disk sequentially when flushed then it would be possible for the confirmation data to be written before the content data.\n\nThere are two obvious ways around this, but both are undesirable:\n\n\nFlush the content, then write the confirmation and flush it. Adding the extra flush may degrade performance.\nInclude a checksum in the confirmation (would require reading the content to confirm that it is valid).\n\n\nI'm using C# on Windows (32 and 64-bit) and .Net 4.0's memory mapped file implementation"

"Parsing an array from recursion function C++",
"So I a little new to C++ and discovery what I can and can't do in comparison to python. Basically I have a function and inside that function I want to parse through an array and some integers run it, and return the output number. But it seems to prove a little tricky. Wondering where I am messing up. \n\nSince the function it contains in is dominated by recursion I can't just make it a global variable where the array values are static. \n\nSo here is an outline of the code\n\nvoid sequenceAlignment(int iStart,int jStart,int kStart, int seqLen1Size, int seqLen2Size, int seqLen3Size) {\n\nint lengthi = seqLen1Size - iStart;\nint lengthj = seqLen2Size - jStart;\nint lengthk = seqLen3Size - kStart;\n/* Sets it as a floor */\nint midpoint = (seqLen1Size + iStart) / 2;\n\n/*End the recursion*/\nif (lengthi <= 1)\n return;\n\n/*We set two scoring arrays and intialize the XY Plane in the 3D */\nint forwardScore[2][lengthj + 1][lengthk + 1];\nint backwardsScore[2][lengthj + 1][lengthk + 1];\n\n\n/* Some code */ and then to this \nforwardSubscoringCalculation(multidimensionalarray, int, int, int, int, int, int)\n\n\nThe Function that is being called\n\nvoid forwardSubscoringCalculation(int forwardScore, int scorei, int scorej, int scorek, int scoredArrayi, int scoredArrayj, int scoredArrayk) {\n\n int tempValueHolder = 0;\n int subscore[3] = {-10000, -10000, -10000};\n\n subscore[0] = forwardScore[scorei][scorej][scorek] + scoredArray[scoredArrayi][scoredArrayj][scoredArrayk];\n}\n\n\nI am wondering how can I exactly do this. I thought by setting up the array it also acts like a pointer and be passed through but I might screwing that up. Is it possible in this code or can it be quite tricky?\n\nEDIT Minimal Code \n\nvoid score(int, int, int, int, int, int, int);\nvoid function(int, int ,int, int, int, int)\n\n\nvoid function(int i, int j, int k, int l, int m, int n) {\n\n int forward[Number][Number][Number];\n for (x = 0; x >= l; x++){\n score(forward, i + x, j, k l, m n) \n }\n}\n\nvoid score(int array, value1, value2, value3, value4, value 5, value6){\n /* Do some stuff with the array */\n}"

However, the reference to the 'overflow' property of the div is coming back 'undefined' so that I can't set it to 'scroll.' Any idea why the ref to the div's overflow is coming back 'undefined'? I think that would fix the problem (and make the scrollbars show up).\n\nHere's the div:\n\n<asp:Panel ID=\"textStatement\" class=\"textStatement\" runat=\"server\"></asp:Panel>\n<label id=\"candidateStatementShowMoreLess\" class=\"MoreLess\" onclick=\"ShowMoreLess(this)\">Show More</label>\n\n\nHere's the javascript (using jQuery):\n\nvar IsStatementExpanded = false;\nvar IsDescriptionExpanded = false;\n\nfunction ShowMoreLess(moreLessLink)\n{\n var section = $(moreLessLink).prev(\"div\");\n var sectionId = $(section).attr(\"id\");\n var collapsedHeight = 70;\n var expandedHeight = 300;\n\n if (section.height() == collapsedHeight)\n {\n section.animate({ height: expandedHeight }, 500,\n function ()\n {\n $(moreLessLink).html(\"Show Less\");\n\n // ***** This should be setting the overflow to scroll on the div, but isn't, as \"attr\" is coming back undefined. *****\n section.attr(\"overflow\", \"scroll\");\n });\n\n if (sectionId == \"textStatement\")\n {\n IsStatementExpanded = true;\n }\n else if (sectionId == \"textDescription\")\n {\n IsDescriptionExpanded = true;\n }\n }\n else\n {\n section.animate({ height: collapsedHeight }, 500,\n function ()\n {\n $(moreLessLink).html(\"Show More\");\n\n // ***** This could have the same problem as above, but when the user collapses the div. *****\n section.attr(\"overflow\", \"hidden\");\n });\n\n if (sectionId == \"textStatement\")\n {\n IsStatementExpanded = false;\n }\n else if (sectionId == \"textDescription\")\n {\n IsDescriptionExpanded = false;\n }\n }\n}"

"Execute SQL Server request in the callback of an HttpWebRequest",
"My understanding is that two HttpWebRequest callback can be executed at the same time because the request are asynchronous. However, I want to work with the database on the callback, and it seems not possible with SQL Server. What is the best practice in this case ? Is there a way to add these requests to a queue, or should I use something like mutexes (which I would prefere to avoid, since deadlocks are difficult to debug) ?\n\nedit: My current code doesn't do anything special to prevent that. I fire multiple (different) requests and sometimes in one of the callbacks I get a exception thrown (\"Invalid Cross Thread Access\") when I try to submit the changes to the database.\n\nI tried to use Dispatcher.BeginInvoke but now I have doubts that it's doing what I want after some googling (I used Dispatcher.BeginInvoke before successfuly when accessing elements in my XAML, so I thought it could fix my problem accessing the db)"

And if I have to, knowing that Rest application must be stateless, should I use OAuth(with a little state part) + JWT excluding HTTP Session authentication ?\n\nThank you so much, there is some concepts I do not understand.\n\nEdit : globally, the question is when to develop a simple REST application and when to develop authentication part for security ?"

I.e. not a JVM crash but a normal, controlled exit from a Java program.\n\n\n\nAfter thinking it over, I think that it would be sufficient for our purposes to create a set of text files (or perhaps just pipe in a single text stream) to a tiny Windows application located inside our part of the file system.

"Android AlertDialog - How do I handle extremely large message?",
"I'm popping up an AlertDialog when a ListView item is clicked and the string of the message is very large (nearly 20,000 characters). What winds up happening is that I click the list item and it sits for about 3-4 seconds before displaying the AlertDialog. This is problematic for many reasons, primarily that the user could click the button repeatedly and crash the app.\n\nMy first thought was to try to mimic how the Google Play app handles their open source license display (Play -> Nav Drawer -> Settings -> Open Source License info), where they pop open the AlertDialog and then it looks as though the view/text is loaded after the dialog is shown. I imagined it looking something like this:\n\nAlertDialog.Builder builder = new AlertDialog.Builder(this);\n builder.setTitle(title);\n builder.setMessage(veryLongStringMessage);\n builder.setCancelable(true);\n builder.setNeutralButton(android.R.string.ok, listener);\n\n final AlertDialog alertDialog = builder.create();\n alertDialog.show();\n\n\nPretty basic stuff up until this point. Then I've tried to remove the message set in builder for something like:\n\nbuilder.setMessage(\"\")\n// create/show dialog as above\nalertDialog.setMessage(veryLongStringMessage);\n\n\nBut that seems to just load the whole dialog before showing it. So I thought maybe post a runnable to go at the end of the activity calls, and that wasn't working. I tried doing this in an Async task and could not get it working that way either. I've tried this as a DialogFragment where I call\n\nactivity.getSupportFragmentManager().executePendingTransactions();\n\n\nThen go on to try to set the message after I know the DialogFragment has been shown and I either wind up with an empty dialog (the new message won't show up) or it loads it all at once and I'm sitting with that 3-4 second delay.\n\nAnyone have any good method of implementing and AlertDialog with a very large message?"

"Use one or multiple random number generators for genetic algorithms?",
"I'm implementing a genetic algorithm using Java programming language. As you know, there are some random events in the algorithm like roullete selection, crossover, mutation, etc. In order to generate a better probability distribution among these events, which approach should be better, to use a unique Random object or create a separate Random object for each event?"

"for loop help and storing expression results",
"completely new to java and struggling with my assignments, I don't just want to ask for answers but the tutors are not even giving me the methods to use to write my code so I am struggling.\nthe advice given to me is to tidy up the formatting of the code so all the lines are either at the same level or cascade in one direction. needless to say this did no help.\nI feel I am close, but might benefit from a push in the right direction.\nthe question is: In this part you will write a public method calculateCheckNumber() to find S and then use the expression given in part (d) to find C. The method should first create a string omitting the last digit of the longNumber and then find S by iterating through this string. (You may choose to do a separate iteration for the odd and even indexes, or you could do both in a single loop.)\nFinally, your method should calculate and return the value of C using the expression given in (d). Choose meaningful identifiers for your variables.\nExpression:\nCheck that the long number has exactly 16 digits. If not, the long number is not valid.\nIf the long number has 16 digits, drop the last digit from the long number, as this is the "check digit" that we want to check against.\nMultiply by 2 the value of each digit starting from index 0 and then at each even index. In each case, if the resulting value is greater than 9, subtract 9 from it. Leave the values of the digits at the odd indexes unchanged.\nAdd all the new values derived from the even indexes to the values at the odd indexes and call this S.\nFind the number that you would have to add to S to round it up to the next highest multiple of 10. Call this C. If C equals the check digit, then the long number could be valid.\n public class CreditCardChecker\n {\n // Variable for long numbers to be checked\n public String longNumber;\n public int checkDigit;\n public int checkSum;\n public int evenNumber;\n\n /**\n * Constructor for objects of class CreditCardChecker\n * including long number\n */\n public CreditCardChecker(String longNumber)\n {\n // initialise long number variable\n this.longNumber=longNumber;\n this.checkDigit=checkDigit;\n this.checkSum=checkSum;\n }\n /**\n * Sets the value of long number\n */\n public void setLongNumber(String aLongNumber)\n {\n this.longNumber=aLongNumber;\n }\n /**\n * method to get the long number\n */\n public String getLongNumber()\n {\n return this.longNumber;\n } \n /**\n * method to check that long number has exactly 16 digits\n */ \n public boolean isCorrectLength()\n {\n if (longNumber.length() == 16)\n {\n return (true);\n }\n else\n {\n return (false);\n }\n }\n /**\n * Method to get the first 15 characters of long number\n */\n public String firstFifteen()\n {\n return longNumber.substring(0, 15);\n }\n /**\n * Method to calculate the check number from the long number\n */\n public int calculateCheckNumber()\n\n { \n int checkSum=longNumber.charAt(15);\n evenNumber = Integer.parseInt(longNumber);\n for(int longNumber=0; longNumber<= 15; longNumber++){\n System.out.println(evenNumber);\n if (evenNumber %2==0)\n return (evenNumber *2);\n \n if (evenNumber>=9)\n return (evenNumber-9);\n checkSum = evenNumber + evenNumber++;\n }\n return this.evenNumber;\n }\n\n }"
