how to make an object an instanceof of its own prototype's property
taking a standard browser as example, there is the Window class instantiated as window variable window variable also contains the Window constructor (window.Window) so, how to reproduce this structure? test this in your (standard) browser: alert(window instanceof window.Window);

Checking for and installing prereqs with Install Shield
I'm creating my first install using the Install Shield version that ships with VS 2010. On vista and 7 only the .NET 4.0 client is required, but on XP my application reqires: 1. .NET 2.0 (I think this is required for the following prereqs) 2. XP Update KB968930 (Windows Management Framework Core) 3. XP Update KB971513 (Microsoft Active Accessibility Package) 4. SAPI 5.1 (Text to Speech and Speech Recognition) When testing the application I've just manually run the exe for each of those (for SAPI I used the old SAPI 5.1 sdk to make sure it's installed which seems overkill). I was thinking of just creating an exe file which would run all four executables and then run the installer (or I think I could via a VB Script inside Install Shield?) I'm wondering if there is a cleaner way to check for these, prompt the user for each one, and then quietly install as part of the install using Install Shield? Or just a simple way to package them into an install. Thanks for your help!!

PuTTY (or any ssh-like): Opaque Text and Transparent Background
I know it was already asked here http://stackoverflow.com/questions/711181/putty-with-transparent-background-and-opaque-text BUT the post is really old. KiTTY doesn't work with it anymore (althou the option is still there). Console 2 makes the whole window transparent even the text which isn't usable at all. Other versions of PuTTY with this feature enabled are really old and (for me) unsecure. So, what is your solution for opaque text and transparent background on a shell for Windows?

Does LINQ skip & take have decent performance?
We have a query for about 40 data fields related to customers. The query will often return a large amount of records, say up to 20,000. We only want to use say around the first 500 results. Then, we just want to be able to page through them 10 at a time. Is LINQ skip and take a reasonable approach for this? Are there any potentnialy performance issues with using this approach vs doing it manually some other way?

ButtonDown and ButtonUp using boolean?
so basically I am using a custom controller for input, that sets a boolean value to true as long as a button is held, and false while the button is released. I need to be able to make an event fire once when the button is first pressed and when it is released. Does anyone have any advice? P.S. I am using C# with the .Net Framework.

Entering data into a grid
A UI question: is there some consensus on the best (defined as "the one which end-users like best") or least-bad way to implement data entry into a grid? I have a grid, with many rows. The grid's columns contain various types of properties, which the user can enter/edit. The "types" of properties include: * Free text * Numbers (numeric digits) * Enum value (e.g. one of 'High', 'Medium', and 'Low') * Others (e.g. date, duration) The 'free text' type isn't difficult to design (so I won't ask about that), but what about the next two types? **Numeric digits** * When using a keyboard to enter a number, would you allow free-text entry, and then run a validate method on blur? Or, monitor each key-press to restrict the data entry to digits only? * How do you tell the user (on a grid, not on a form) that the syntax of the data in some column is restricted to numeric-only? What do you do if the user presses a wrong (non-numeric) key? * A 'spin' or 'spinner' control is a standard Windows control; is it appropriate to try to use one on a HTML-based grid as well? **Enum values** For entering or editing an enum value using the mouse, I guess that popping a little context menu on a mouse click is the thing to do. * An alternative is to use the `<select>` input control (i.e. a combo box). I guess though that having a whole column-ful of combo boxes isn't as easy to read as having a column of text value (because the combo boxes add extra non-text ink)? What do you think of usually displaying plain text, but replacing that text with a combo box when the field gets the input focus (and then removing the combo box on blur)? * Would you also pop that same menu on focus, when the focus changes as a result of the keyboard (i.e. the [Tab] key) instead of a result of the mouse (i.e. a click)? In other words, should tabbing to a field result in a popup menu? Incidentally, the CSS-based popup menus that I've seen respond to the mouse but not to the keyboard (e.g. to the [Up] and [Down] arrow keys). Do you know of any Intellisense-like data entry implementation that can run in a browser? **For example?** I'd also be interested in seeing anything you think is an exemplary example. I'm interested in desktop UI and/or in-browser answers.

Am I not doing correctly or understanding double buffering on Android?
I have a function @Override public void run() { while(running && (!eof)){ if(surfaceHolder.getSurface().isValid()){ Canvas canvas = surfaceHolder.lockCanvas(); paint(canvas); surfaceHolder.unlockCanvasAndPost(canvas); } } thread = null; } where paint(canvas) calls a bunch of other functions that draw a graph and text, for example canvas.drawText("Time="+myRecord.getMyTime(), 100, 100, paint); The problem I'm having is that the graph and the text, both of which should be constantly changing, don't get erased but instead keep drawing over themselves. Shouldn't my entire canvas get redrawn every time because that's how double buffering works with the lock() and unlock()? Am I not understanding this correctly? How am I supposed to do this?

What is the best way to partition terabyte drive in a linux development machine?
I have a new 1 TB drive coming in tomorrow. What is the best way to divide this space for a development workstation? The biggest problem I think I'm going to have is that some partitions (probably /usr) will become to small after a bit of use. Other partitions are probably to huge. The swap drive for example is currently 2GB (2x 1GB RAM), but it is almost never used (only once that I know of).

Is the HTTP package server safe to use in production?
Go implements [FastCGI][1], as well as a native [HTTP server][2] in its standard library. Is it safe to use the server from the HTTP package in production (as an application server) or is it recommended to use the FastCGI interface to connect to a more robust solution like Apache in terms of security?

Java Wicket - Calling javascript ( JQuery ) before AJAX
I got this thing i'm trying to solve: I got a ListView created using Wicket ( 1.5 ) with a lot of elements and a scroll. When new items are available, the user is asked if he would like to refresh the list via a message backed by an AjaxLink: public void onClick(AjaxRequestTarget ajaxTarget) { /* do something ... */ ajaxTarget.addComponent(_list); } So on click the list gets reloaded and the scroll position is reset to zero. Is there any way i can call JavaScript before the list reloads the save the scroll position? (I know how to get/save the scroll position ( .scrollTop() ) , i just don't know how to call a function right before AJAX ).

How the given C code be interpretated by different Compiler
I have a code below and wanted to know what could be output.What i would like to see how different compiler would interpret this particular piece of code. int main() { int i = -1, j = 2, k = 0, m; m = ++i || ++j && ++k; printf("\n %d %d %d %d \n", i, j, k, m); return 0; } Now the question is while handling this code would compiler go by the rule which says This expresion can be seen as m = ++i || (++j && ++k); as && has higher precedence over || and the result would be -2 2 0 1 or This expresion can be seen as m = ++i || (++j && ++k); but compiler still will try to short circuit. so it evaluates ++i, since it's 1,(++j&&++k) are not evaluated.so ans is -2 2 0 1

Interview coding test how to approach the style aspect.
I have taken a couple of coding test lately all timed, but without a limit meaning I could take as long as I want, but they wanted to see how long it took me. Given this criteria i have opted to use the most straight forward style possible while refactoring little in order to solve the problem quickly. I have received a couple of offers so I guess I did good enough, but was curious as to how other approach coding tests.

Thread syncronization
I have one thread that locks a mutex, writes a value to a variable, unlocks the mutex. I do a print out here and the value has been changed. I set it to 1. When I read the variables value in another thread using lock, unlock on the mutex and read the value, I get the old value of 0. Why is this happening. I lock and unlock the same mutex correctly. How do I sync threads?

Stretching the items of an ItemsControl
I'm bulding a small WPF app over here. It's all built strictly with MVVM, using nothing but DataTemplates linked to view model types. I've seen alot of questions about how to stretch and clip the contents of `ListBox`es so that the items fill its parent. After alot of experimenting I managed to get my head around that but now I find myself in the same scenario with the `ItemsControl` but the same tricks doesn't seem to work. Here's one of the `DataTemplate`s in use (a simple `TextBox`). Note how I tried setting the `HorizontalAlignment` ... <DataTemplate DataType="{x:Type vm:OneOfMyViewModelTypes}"> <TextBox Text="{Binding Path=Value}" HorizontalAlignment="Stretch" /> </DataTemplate> Here's the `ItemsControl` inside a `Grid` ... <Grid Background="Gray"> <Grid.Margin> <Thickness Left="{StaticResource ConfigurationDefaultMargin}" Right="{StaticResource ConfigurationDefaultMargin}" Bottom="{StaticResource ConfigurationDefaultMargin}" Top="{StaticResource ConfigurationDefaultMargin}" /> </Grid.Margin> <Grid.ColumnDefinitions> <ColumnDefinition SharedSizeGroup="_key" Width="Auto"/> <ColumnDefinition SharedSizeGroup="_value" Width="*"/> </Grid.ColumnDefinitions> <ItemsControl Background="DimGray" Grid.IsSharedSizeScope="True" ItemsSource="{Binding Path=Configuration, Mode=OneWay}" HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch" > <ItemsControl.ItemTemplate> <DataTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition SharedSizeGroup="_key"/> <ColumnDefinition SharedSizeGroup="_value"/> </Grid.ColumnDefinitions> <TextBlock Style="{StaticResource ExtensionConfigurationLabel}" Grid.Column="0" Margin="5,5,5,0" Text="{Binding Path=Caption}" /> <ContentPresenter Grid.Column="1" HorizontalAlignment="Stretch" Margin="5,5,5,0" Content="{Binding}" /> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> </Grid> I've used colors to see how the controls sizes. The `Grid` is gray and the `ItemsControl` is dark gray. This is the result ... ![This is the result][1] As you can see from the colors the containing `Grid` stretches while the `ItemsControl` does not. I did set its `HorizontalAlignment` property to `Stretch` but it seems it has no effect. Is there anything else I need do? Thanks [1]: http://i.stack.imgur.com/0RvU4.png

This object should provide a mechanism to store a word to be guessed,the letters that have already been guessed, and the current state of the word to be guessed. The game should also store the maximum number of misses allowed as well as provide a mechanism for determining whether the game is over and whether the game has been won. using the following UML diagram -maxMisses : int The Maximum nubmer of incorrect guesses allowed -missCount : int The current number of incorrect guesses -word : string The word to be guessed -correct : String A string that displays dashes for the unguessed letter and letters where correctly guessed -misses : String A string tht hold guessed letters that aren't in the word +correct () : String Returns a string that displays dashes for each letter not guessed and letters where correctly guessed. +gameOver () : boolean Returns true if the game is over, false otherwise. A game is over if the word has been guessed correctly or if the maximum number of allowable misses has been reached. +gameWon () : boolean Returns true if the game has been won, false otherwise. A game is won if the game is over and the word has been correctly guessed. +guess (char c) Searches the word to be guessed for the presence of c. If present, replaces all the corresponding spaces in the correct word, if not present, increments miss count and adds c to the missed letters string. +initialize (String word, int maxMisses) Takes a String that is the word to be guessed and an integer that represents the maximum number of incorrect guesses allowed. +lettersMissed () :String Returns a String containing all the letters guessed that are not in the word to be guessed. +maxMissesAllowed () : int Returns the maximum number of misses allowed +misses () : int Returns the current number of misses. +word () : String Returns the word to be guessed. Implementation Implement the Hangman class provided above. Your implementation must match the UML diagram given. Test your implementation by creating another class with a main method, create a Hangman object with a hard-­‐coded word and write the code necessary to “guess” letters to make sure your Hangman object works properly. You may hard-­‐code these guesses simply to test your implementation. Some Examples • The correct method returns a string composed of the same number of dashes as are letters in the word. For instance, if the word is “gobble” the following is returned from the correct method: -­‐-­‐-­‐-­‐-­‐-­‐ • The player guesses a letter. If the letter is in the word, that letter replaces its corresponding locations in the correct string. For instance, if the player guesses ‘e’ the following is returned from the correct method: -­‐-­‐-­‐-­‐-­‐e • If the letter is not in the word, it is added to the String of “misses.” For instance, if the player next guesses ‘a’ the following is returned from the lettersMissed method: a • If there are multiple occurrences of a letter in the word, all occurrences are replaced. For instance, if the player next guesses ‘b’ the following is returned from the correct method: -­‐-­‐bb-­‐e • Guessing a letter that has already been guessed counts as a miss. For instance, if the player again guesses ‘b’ the following is returned from the lettersMissed method: ab

How to create a .tmx file "data"?
I am currently trying to create a random map using tileD but I couldn't manage to decode the "data" in the .tmx file. I read that the data is base64 encode and gzip compressed but none (of what I've searched) actually has got some useful results. Has anyone successfully decoded the "data"? Can I have a full example of how the "data" looks like in xml? If anyone knows what is the format for creating the "data" in XML can you share with us?

how to pick the right Javascript MVC framework?
I am new to javascript and trying to figure out a good JS MVC framework to use I am trying to figure out how to compare and contrast the Javascript MVC frameworks that have been famous recently in the year 2011. I am trying to pick one for my application. My main aim is to pick one so that i can build a solid and well maintainable Js code, easy UI refresh, lesser manual DOM manipulation, faster UI refresh using ajax call to REST services etc.. I am weighing on ember.js, Backbone.js, Knockout.js and Spine.js .. backbone and spine claim as MVC and knockout.js as MVVM. How are they different? is there any other frameworks to be noted? thanks a lot

Trouble serializing vectors in a sub-class in AS3
Hey there! I'm trying to serialize data in AS3 but am running into a frustrating problem. Here's a snippit of code: registerClassAlias("myObjClass", myObjClass); var bytes:ByteArray = new ByteArray(); bytes.writeObject(myObj); bytes.position = 0; myObj = Vector.<myObjClass>(bytes.readObject()); Originally I had problems with "myObjClass" not being convertable, but after I "registerClassAlias"'d it, it happened to come out just fine. Using this block of code everything works fine, and I'm able to pull values from the myObj vector. Some time later, I added vectors to the myObjClass as well, of type "String" and "XML." eg: var newObj:myObjClass = new myObjClass(); newObj.mySubXML = new Vector.<XML>(); newObj.mySubString = new Vector.<String>(); When I run my original block of code, I get these errors: TypeError: Error #1034: Type Coercion failed: cannot convert __AS3__.vec::Vector.<Object>@3aabc11 to __AS3__.vec.Vector.<XML>. TypeError: Error #1034: Type Coercion failed: cannot convert __AS3__.vec::Vector.<Object>@3aabc41 to __AS3__.vec.Vector.<String>. This seemed familiar, as earlier I stumbled across this bug (which Adobe acknowledged and is working on): https://bugs.adobe.com/jira/browse/FP-6693 The workaround was to: registerClassAlias("String", String); ... Which worked fine back in the day. Now that I'm trying to register a class alias for a string that's in a vector in a vector, I don't know how to do it! this doesn't do the trick: registerClassAlias("String", String); registerClassAlias("XML", XML); registerClassAlias("myObjClass", myObjClass); var bytes:ByteArray = new ByteArray(); bytes.writeObject(myObj); bytes.position = 0; myObj = Vector.<myObjClass>(bytes.readObject()); I also tried to "RegisterclassAlias" within MyObjClass too but that didn't work. Help!

What is a good "active installs" rate for a free Android app?
My free app has received many positive reviews and has a 4.5 star rating on the Android Market, but the active install rate is less than 40%, meaning more than half the people who download it uninstall it. Is this normal? I would assume a highly-rated app would have closer to 100% install rate.

I have my server configured like this (this is on a fresh install of ubuntu 10.10) nginx + gunicorn + django + supervisord to run it when I try to access my site, I get a 502 error. and this will show up in the error log: 2011/06/03 10:40:59 [error] 15066#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: [retracted], server: [retracted], request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:29000/", host: "[retracted]" Here is my nginx.conf http://pastebin.com/t0V2yFxr Here is my supervisord.conf http://pastebin.com/pqVqRLSk and my gunicorn.conf bind = "127.0.0.1:29000" logfile = "/sites/[retracted]/logs/gunicorn.log" workers = 3 when I run sudo supervisordctl status it returns nothing. So this makes me suspect that it is not properly running. However, there is no supervisord.log file (in /var/log/ or in /code/[]/logs/) or gunicorn.log showing errors. So I cannot debug this at all. Any suggestions on how to get this takin care of?

How to go back from second screen to first screen
I have probably easy question, how to swich layouts, but its little complicated for me. Firs I have a class Main where is onCreate (setContentView(R.layout.main);) and than I call, another class with command: setContentView(secondClass); In this clas i draw with Canvas and this work just fine and i also create button to go back in first "class" (R.layout.main), but i dont know how to do it. Now my program is basic a graph shower. In first class you type your function and them second class draw it. But how to go back in first class to type another function. This "back" button or arrow witch every android phone have, send me out of program not back on insert part. In secondClass I cant create onCreate method, but I also tryed and this didnt work: - Intent abc = new Intent("bla.bla.bla.FIRSTCLASS"); startActivity(abc); - Intent abc = new Intent(SecondClass.this,FirstClass.class); startActivity(greNaPrvoOkno); I know my English is bad. Hope you understand Thank you

Is this the correct approach to design a shopping cart Android application?
I have a requirement to develop a shopping cart Android application. The features should include 1. Ability for any customer to register 2. Ability to login with his credentials 3. Search and select products 4. View history about his previous purchases 5. Make payment to get the products delivered to his billing address. I have done some analysis and below are my thoughts. Server Side: Java web application Client Side: Android application 1. Design Android application with an Activity to allow customers to register themselves. 2. Design another Activity to enable customers to login to the application (authenticate customer by sending his credentials through HttpClient to a Java servlet. Once the customer is authenticated successfully, generate a unique token id at the server end store it in the database and send it to the Android client app. Is this the correct approach to remember the customer (similar to session management) for his further interactions with the application?) 3. Provide customers the ability to search and select desired products (use above created unique token for further interaction with server). 4. Provide customers the ability to view his history of purchases. 5. Provide customers the ability to make payments. (Can i take customer PayPal credentials from Android app and use PayPal API to pragmatically make payments at server end? Is it correct approach? Can someone please suggest me with correct approach / best practices and with sample code if possible? Thanks,

Clipping window rendering to a region
I have a window that is 100x100, but I only want to draw 50x100 and leave the right-side transparent without using WS_EX_LAYERED. The Windows Taskbar appears to do this when auto-hide is enabled. The Taskbar is 40px tall according to GetWindowRect, but only 2px is visible. How is it possible to have a window that is larger than what is shown on the screen without making it a layered window?

What optimizations does Python do without the -O flags?
I had always assumed that the Python interpreter did no optimizations without a `-O` flag, but the following is a bit strange: >>> def foo(): ... print '%s' % 'Hello world' ... >>> from dis import dis >>> dis(foo) 2 0 LOAD_CONST 3 ('Hello world') 3 PRINT_ITEM 4 PRINT_NEWLINE 5 LOAD_CONST 0 (None) 8 RETURN_VALUE It appears as though the interpreter is doing some folding on the modulo of two string constants. If I add a variable in though, it gives an unoptimized result: >>> def foo(): ... s = 'Hello world!' ... print '%s' % s ... >>> dis(foo) 2 0 LOAD_CONST 1 ('Hello world!') 3 STORE_FAST 0 (s) 3 6 LOAD_CONST 2 ('%s') 9 LOAD_FAST 0 (s) 12 BINARY_MODULO 13 PRINT_ITEM 14 PRINT_NEWLINE 15 LOAD_CONST 0 (None) 18 RETURN_VALUE What optimizations does Python do without the -O flag? And is there any way to disable them? I'd like to see how unoptimized Python bytecode will look. I don't plan on doing this in any production type environment.

C/C++ Optimizations
So, I've been raised in a very OO manner when it comes to programming... which has unfortunately meant that hightly optimized code is not my forte. I'm fairly good at C now and can usually do things in reasonably intelligent ways, but I still have trouble thinking of the most optimized way to handle situations. One example would be: int strlen(const char* str) { char* s; for (s=str; *s; ++s); return s-str; } I would never have thought of that myself. So, what are some good resources that expose you to optimized code like this? I'd like to find a place where I could read up on the theory behind it, what the compiler does in the background which makes it worthwhile, etc. It would also be nice if some resources were noted for studying optimized data structures with application to real-life scenarios, but that's probably too much to ask. Thanks in advance! -w00te

Alfresco in Tomcat: OutOfMemory
I've recently installed Alfresco 4.0d, with the 32 bit executable. Whenever someone accesses the application, I get OutOfMemory error. I've googled it and saw that more memory needs to be added. So, I've tried editing the setenv.bat file in Alfresco's tomcat, like this: set JAVA_HOME=D:\Alfresco\java set JAVA_OPTS=-server -Xss1024K -Xms1G -Xmx2G -XX:MaxPermSize=128M -XX:NewSize=512m However, the error still occurs. I notice in the task manager that tomcat6.exe doesn't use more than 960mb, so my options aren't applied to it? Regards, Nuno.

Application is not working under raw system.
I've an python GUI application, I use pyQt4. I build binary with bbfreeze (before I was using py2exe but it didn't work with email module well). On system where I build this app, everything works properly, but when I install it on raw windows (without all those vc_redist and set of python libraries) binary does not work. Where should I start to find a solution, since I have no messages/exceptions/crashes, it simply ends immediately after i run it from command line. I predict that if I'd install some of tools from "build system" I would run it. Is this the only way? I mean, if I would find the missing lib (if it's a lib problem), would adding this library to bbfreeze script would solve this problem? cheers P.

DatastoreService Batch Delete. What happens if an exception occurs
I perform batch delete operation on entity keys using DatastoreService.delete(Key... keys). Each entity is a root entity, so operation is executed without transaction. The batch size is hardcoded and the deletion is performed step by step. Each following operation firstly execute key-only get query to fetch entity keys using cursor received from previously executed get query and then performs batch delete query. Scheme seems to work fine, but what if an exception occurs while delete query? Is there any way to get a number of successfully deleted entites, or a cursor of the first not deleted entity? And could you please clarify how this operation is performed in GAE on low-level.

how to initialize a Simgleton?
Sometimes there is a need to initialize the singleton class with some helper values. But we can't "publish" a constructor for it. What is the walkaround for this? For more clarity I provide a sample: ''' <summary> ''' Singleton class MyPainter ''' </summary> Public Class MyPainter Private Shared _pen As Pen Private Shared _instance As MyPainter = Nothing Private Sub New() End Sub ''' <summary> ''' This method should be called only once, like a constructor! ''' </summary> Public Shared Sub InitializeMyPainter(ByVal defaultPenColor As Color) _pen = New Pen(defaultPenColor) End Sub Public Shared Function GetInstance() As MyPainter If _instance Is Nothing Then _instance = New MyPainter End If Return _instance End Function Public Sub DrawLine(ByVal g As Graphics, ByVal pointA As Point, ByVal pointB As Point) g.DrawLine(_pen, pointA, pointB) End Sub End Class Thanks.

Is there any way of reading a timecode track of a uicktime movie with applescript

By using this script tell application "QuickTime Player" set themovie to open thefile set thetracks to tracks of document 1 repeat with thetrack in thetracks if the kind of thetrack is "Timecode" then get the properties of thetrack end if end repeat end tell I can get the timecode track, the properties of the track are: > {is audio variable rate:true, is video > gray scale:false, audio sample size:0, > class:track, audio sample rate:0.0, > sound balance:0, preload:false, > streaming bit rate:-1.0, > duration:960300, language:"English", > audio channel count:0, layer:0, > contents:missing value, bass gain:0, > start time:0, data format:"Timecode", > treble gain:0, audio > characteristic:false, sound volume:0, > mask:missing value, video depth:0, > position:{0, 0}, id:4, high > quality:false, deinterlace > fields:false, href:"", natural > dimensions:{0, 0}, single field:false, > kind:"Timecode", index:4, data > size:38412, visual > characteristic:false, data rate:100, > never purge:false, transparency:49, > chapterlist:{}, name:"Timecode Track", > alternate:{}, operation color:{32768, > 32768, 32768}, enabled:true, > type:"tmcd", streaming quality:-1.0, > transfer mode:transfer mode unknown, > dimensions:{0, 0}, current > matrix:{{1.0, 0.0, 0.0}, {0.0, 1.0, > 0.0}, {0.0, 0.0, 1.0}}} none of which seems to have anything to do with the timecode. Note that the contents property is "missing value" If I try to get the current time of the movie it returns 0, even if the timecode doesn't start at 0. I'm thinking by what I've found on the net so far that this is impossible. Please prove me wrong TIA -stib

PHP never-repeating Random Number
I need to create a completely random number for each user on my website and insert it into a MySQL database. The numbers can never repeat and I don't want to use MySQL AutoIncrement because I need a specific range. Say from `111,111` to `999,999,999,999`. No higher or lower as of right now. I do have a specific reason for that range, incase you were wondering. I know I can use the `unique` feature on MySQL but that only prevents me from inserting duplicates. I was thinking of having 2 functions, one to generate the number, and another to check if that number is used. They would keep looping until they found a number that wasn't used. I know how inefficient that is and how long it may take once majority of those numbers have been taken so that is why I have come here, for a better answer. What do you suggest I do because I am all out of ideas. Thanks for any help!

Why sometimes there are multiple JSF life cycles invoked?
I connected a simple jsf lifecycle listener to my webbapp: public class LifeCycleListener implements PhaseListener { @Override public PhaseId getPhaseId() { return PhaseId.ANY_PHASE; } @Override public void beforePhase(PhaseEvent event) { System.out.println("START PHASE " + event.getPhaseId()); } @Override public void afterPhase(PhaseEvent event) { System.out.println("END PHASE " + event.getPhaseId()); } } On one of the pages I have smth like this: <h:form> <h:commandLink id="avdertAddedToMainPage" action="#{topView.showMainPage}"> Main Page </h:commandLink> </h:form> where topView is simple bean configured in faces-config as request-scoped: public class TopView { public TopView() { } public String showAddAdvert() { return "addAdvert"; } public String showMainPage() { return "itemList"; } } What makes me wonder is that, if I click the above link, everything seems to work properly, but according to LiceCycleListener's output every phase is run by 3 or 4 times before page loads up. Is this normal behaviour? If this indicates some kind of bug in my code, where I should look for it? I use Mojarra 2.0.2 on Glassfish 3.0.1

C#: Getting an RSS feed posted to Google Plus
I'm trying to use either the Google Plus API or GooglePlusLib for .NET to have entries from an RSS feed posted as a Google Plus post (or "activity"). I have all the info necessary (apikey, OAuth2.0 info, profile info) but am kind of clueless as to how to put it all together. I have done a lot of searching but can't seem to find what I'm looking for. This page seems the closest to what I need: http://www.eggheadcafe.com/tutorials/csharp/8c81f554-1028-40d6-bab0-604bb11153d6/googlepluslib-net-client-library-for-google-api.aspx Ideally I'd want an XML document (app.config) to hold the info (apikey, OAuth key, RSS url) and then have a GooglePlusLib or just Google+ API command post to my Google+ profile. But I have looked through both references (through object browser) and can't find any commands that jump out as something that would help me. If it is not possible to post to Google+ from an RSS feed then what about posting results from a Google News search? I'm using Visual Studio 2010 .NET, C# language. If someone can give me some clues that would be great. Thank you.

I have in my table this value ART(\'O\') in the field Subject. How do I check if this subject exist? I tried: select * from table1 where Subject = 'ART(\'O\')'; select * from table1 where Subject = "ART(\'O\')"; Both failed at picking up the record. How sholud I prhase the query so that the record containing ART(\'O\') will be picked? Note: Please do not refer the query: select * from table1 where Subject like '%ART(%'; bec they may be other records such as ART(EX), ART(NA),etc... existing Need to know how to use the Subject = '' method.

How to bind large amount of data in chart plotter control of D3
i am working on a WCF application which is used to show real time sensor info which coming from database.For this i am using DynamicDataDisplay chart plotter.It works fine here for small amount of data. Problem : When i try to bind large amount of data then it take more time to respond.Before posting question here i have done some home work.I check all the facets which may be responsible for this late binding and i found for loop which is using to bind plotter. **Xaml file :** <d3:ChartPlotter Name="plotter" Margin="3,121,5,0" Grid.RowSpan="2" Height="373" VerticalAlignment="Top" VerticalContentAlignment="Stretch" LegendVisible="False"> <d3:ChartPlotter.HorizontalAxis> <d3:HorizontalDateTimeAxis Name="dateAxis" /> </d3:ChartPlotter.HorizontalAxis> <!--<d3:Header FontFamily="Georgia" Content="Readings"/>--> <d3:VerticalAxisTitle FontFamily="Georgia" Content="Sensor Readings" /> <d3:HorizontalAxisTitle FontFamily="Georgia" Content="Date" /> </d3:ChartPlotter> .CS : Dataset ds = "Contain data for selected sensors"; Color[] colors = ColorHelper.CreateRandomColors(SelectedSensorColumn.Count); for (int i = 0; i < SelectedSensorColumn.Count; i++) { List<SensorInfo> Sensor = new List<SensorInfo>(); Sensor = LoadSensorRates(ds, SelectedSensorColumn[i]); plotter.AddLineGraph(CreateSensorDataSource(Sensor), colors[i], 1, SelectedItems[i]); } Method : private static List<SensorInfo> LoadSensorRates(DataSet ds, string column) { try { var res = new List<SensorInfo>(ds.Tables[0].Rows.Count - 1); for (int i = 0; i < ds.Tables[0].Rows.Count; i++) { if (ds.Tables[0].Rows[i][column].ToString() != "") { DateTime date = DateTime.Parse(ds.Tables[0].Rows[i][0].ToString()); double rate = Double.Parse(ds.Tables[0].Rows[i][column].ToString(), CultureInfo.InvariantCulture); res.Add(new SensorInfo { Date = date, Rate = rate }); } } return res; } catch (Exception ex) { throw ex; } } SensorInfo.cs : class SensorInfo { /// <summary> /// Gets or sets the date for which currency exchange rate is given. /// </summary> /// <value>The date.</value> public DateTime Date { get; set; } /// <summary> /// Gets or sets the currency exchange rate. /// </summary> /// <value>The rate.</value> public double Rate { get; set; } } How i can replace for (int i = 0; i < SelectedSensorColumn.Count; i++) { List<SensorInfo> Sensor = new List<SensorInfo>(); Sensor = LoadSensorRates(ds, SelectedSensorColumn[i]); plotter.AddLineGraph(CreateSensorDataSource(Sensor), colors[i], 1, SelectedItems[i]); code so that i can bind plotter with speed.

Why does my sharepoint web part event handler lose the sender value on postback?
I have a web part which is going to be a part of pair of connected web parts. For simplicity, I am just describing the consumer web part. This web part has 10 link buttons on it. And they are rendered in the Render method instead ofCreateChildControls as this webpart will be receiving values based on input from the provider web part. Each Link Button has a text which is decided dynamically based on the input from provider web part. When I click on any of the Link Buttons, the event handler is triggered but the text on the Link Button shows up as the one set in CreateChildControls. When I trace the code, I see that the CreateChildControls gets called before the event handler (and i think that resets my Link Buttons). How do I get the event handler to show me the dynamic text instead? Here is the code... public class consWebPart : Microsoft.SharePoint.WebPartPages.WebPart { private bool _error = false; private LinkButton[] lkDocument = null; public consWebPart() { this.ExportMode = WebPartExportMode.All; } protected override void CreateChildControls() { if (!_error) { try { base.CreateChildControls(); lkDocument = new LinkButton[101]; for (int i = 0; i < 10; i++) { lkDocument[i] = new LinkButton(); lkDocument[i].ID = "lkDocument" + i; lkDocument[i].Text = "Initial Text"; lkDocument[i].Style.Add("margin", "10 10 10 10px"); this.Controls.Add(lkDocument[i]); lkDocument[i].Click += new EventHandler(lkDocument_Click); } } catch (Exception ex) { HandleException(ex); } } } protected override void Render(HtmlTextWriter writer) { writer.Write("<table><tr>"); for (int i = 0; i < 10; i++) { writer.Write("<tr>"); lkDocument[i].Text = "LinkButton" + i; writer.Write("<td>"); lkDocument[i].RenderControl(writer); writer.Write("</td>"); writer.Write("</tr>"); } writer.Write("</table>"); } protected void lkDocument_Click(object sender, EventArgs e) { string strsender = sender.ToString(); LinkButton lk = (LinkButton)sender; } protected override void OnLoad(EventArgs e) { if (!_error) { try { base.OnLoad(e); this.EnsureChildControls(); } catch (Exception ex) { HandleException(ex); } } } private void HandleException(Exception ex) { this._error = true; this.Controls.Clear(); this.Controls.Add(new LiteralControl(ex.Message)); } }

Can i make money with my Android Engine or should I focus on game-making?
I have dedicated past few month to developing my own android 2d engine. You can see its description, demo and tutorials here http://www.aboxengine.com/ ( jar files will be up in a day or two ). While working on the engine I believed it to be better then most available alternatives ( such as andengine, etc. ) and that people would love to use it in their games and, hopefully, would give me some royalties. Yet as I started posting about my engine on other forums, it start looking like people are only interested in free/opensource engines. Based on your experience, what do you think, is there some way for me to make money with that engine or should I forget about selling it and more focus on making games with it myself? Thanks! ![enter image description here][1] [1]: http://i.stack.imgur.com/3uknv.png

Text-align:justify in IE8 - Text moves when clicked on or highlighted
I came with a problem with IE8 text displaying, that the justified text moves a little bit once I click on it or highlight it. Exactly like this http://www.howtocreate.co.uk/ieBugs/floattext.html, except that my div has pixel width. It seems like an IE bug. My question would be, has anybody ever come with this problem? How did you fix it? Thanks!

Javascript - Grid of Checkboxes?
I am about to start a task where I will have a grid of checkboxes which will allow users to select all of the checkboxes, some of them or none of them. I will also add a few conditionals where you can select a checkbox if you have selected the one above it directly and deselect them if the checkbox above has been selected. Before I write this I was wondering if there is something that is already out there than can do this or something similar? Or at the very least something I can build on. I have already bing'ed and Google'd - but nothing has come up for me. I would also appreciate implementation advice as this I don't want this to be a messy job and I can already imagine myself getting into a mess! I would really love it if there was something out there for JQuery as I already make use of this. Thanks all

Openlayers and events on multiple layers (OpenLayer.Layer.Vector)
Another day working with openlayers and another problem. Namely - i have multiple vector layers on top of each other for different types of stuff (cars, trips from history and areas). They all have events that im trying to catch... But as [Niklas][1] found out (http://stackoverflow.com/questions/4728852/forcing-an-openlayers-markers-layer-to-draw-on-top-and-having-selectable-layers), when you activate events on one layer, it gets moved on top and events on layers below wont fire. Is there a way to bypass this? Because when i move over area polygon i want event firing and displaying its name and when i move mouse over to car marker i want the event fire too. And no - i dont want to put them on same layer, cause i want it to be possible to turn them off or on fast and without looping through all the features and disabling them each.

NullReferenceException when adding record to table
I am receiving a NullReferenceException when trying to add a record to a table using LINQ on WP7. I am relatively new to C#/LINQ so I have copied one of my existing methods which works OK, but now I cannot make it work for the new record. The code is below; private ObservableCollection<DBControl.Categories> _category; public ObservableCollection<DBControl.Categories> Category { get { return _category; } set { if (_category != value) { _category = value; NotifyPropertyChanged("Category"); } } } private void button1_Click(object sender, RoutedEventArgs e) { string TestCategory = "Cars"; // Create a new to-do item based on the text box. DBControl.Categories newCat = new DBControl.Categories { CategoryDesc = TestCategory }; //CategoryDesc // Add a to-do item to the observable collection. **Category.Add(newCat);** // Add a to-do item to the local database. BoughtItemDB.Category.InsertOnSubmit(newCat); BoughtItemDB.SubmitChanges(); } The line of code which is giving me the error is **Category.Add(newCat)** As far as I can tell everything looks OK which probably means I've made a daft mistake (again). Any help is much appreciated.

NullReferenceException when adding record to table === I am receiving a NullReferenceException when trying to add a record to a table using LINQ on WP7. I am relatively new to C#/LINQ so I have copied one of my existing methods which works OK, but now I cannot make it work for the new record. The code is below; private ObservableCollection<DBControl.Categories> _category; public ObservableCollection<DBControl.Categories> Category { get { return _category; } set { if (_category != value) { _category = value; NotifyPropertyChanged("Category"); } } } private void button1_Click(object sender, RoutedEventArgs e) { string TestCategory = "Cars"; // Create a new to-do item based on the text box. DBControl.Categories newCat = new DBControl.Categories { CategoryDesc = TestCategory }; //CategoryDesc // Add a to-do item to the observable collection. **Category.Add(newCat);** // Add a to-do item to the local database. BoughtItemDB.Category.InsertOnSubmit(newCat); BoughtItemDB.SubmitChanges(); } The line of code which is giving me the error is **Category.Add(newCat)** As far as I can tell everything looks OK which probably means I've made a daft mistake (again). Any help is much appreciated. The table definition is below; [Table(Name = "Categories")] public class Categories : INotifyPropertyChanged, INotifyPropertyChanging { // Define ID: private field, public property and database column. private int _categoryId; [Column(IsPrimaryKey = true, IsDbGenerated = true, DbType = "INT NOT NULL Identity", CanBeNull = false, AutoSync = AutoSync.OnInsert)] public int CategoryId { get { return _categoryId; } set { if (_categoryId != value) { NotifyPropertyChanging("CategoryId"); _categoryId = value; NotifyPropertyChanged("CategoryId"); } } } // Define item category: private field, public property and database column. private string _categoryDesc; [Column] public string CategoryDesc { get { return _categoryDesc; } set { if (_categoryDesc != value) { NotifyPropertyChanging("CategoryDesc"); _categoryDesc = value; NotifyPropertyChanged("CategoryDesc"); } } } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; // Used to notify the page that a data context property changed private void NotifyPropertyChanged(string propertyName) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } #endregion #region INotifyPropertyChanging Members public event PropertyChangingEventHandler PropertyChanging; // Used to notify the data context that a data context property is about to change private void NotifyPropertyChanging(string propertyName) { if (PropertyChanging != null) { PropertyChanging(this, new PropertyChangingEventArgs(propertyName)); } } #endregion }

Is a Windows Azure worker role instance a whole VM?
When I run a worker role instance on Azure, is it a complete VM running in a shared host (like EC2)? Or is it running in a shared system (like Heroku)? For example, what happens if my application starts requesting 100 GB of memory? Will it get killed off automatically for violation of limits (á la Google App Engine), or will it just exhaust the VM, so that the Azure fabric restarts it? Do two roles ever run in the same system?

Are Strings in .NET encoding agnostic?
My question is simple: Are strings in .net encoding agnostic? I ask this because when I ingest an xml file that I know was encoded with some windows-1252 code page elements (i.e smart quotes), in the debugger viewing the string that is holding my xml seems to want to resolve the single "smart quote" to a triangle with a question mark in it. This makes me wonder if .NET is asserting that the string that is holding my XML is UTF8 and therefore cannot resolve the difference. This is a problem, if so, because if the string gets converted then my webservice that is meant to scrub the windows smart quotes from my text will fail because it doesn't recognize the triangle/question-mark-thingy. Please help.
