Maintaining different repositories under a master project repository
We are into a project that involves many opensource libraries and their code. Our application uses all these libraries code to build an X application. The problem comes when individual libraries get updated and we have to support these updated librayies,which leads to a lot of manual copying of latest code and merging of changes that we made on the previous versions of the updated libraries. We have our own version control in place (perforce) but its repo is there just to version our changes along with all the code of opensource libraries that we use. Is there a way in which the individual libraries can be updated through there own version control systems(they might be using there own versioning systems of their choice git,svn,etc..) by perforce .. i mean we give a command to sync on perforce and it does the individual syncing on individual libs using their respective versioning tool? If perforce cant do this is there another tool than can do this? which one is the preferred tool for such a use case? Thanks.

C# - setting a property by reflection with a string value
I'd like to set a property of an object through reflection, with a value of type string. So, for instance, suppose I have a Ship class, with a property of Latitude, which is a double. Here's what I'd like to do: Ship ship = new Ship(); string value = "5.5"; PropertyInfo propertyInfo = ship.GetType().GetProperty("Latitude"); propertyInfo.SetValue(ship, value, null); As is, this throws an Argument exception (Object of type 'System.String' cannot be converted to type 'System.Double'). How can I convert value to the proper type, based on propertyInfo?

How do I get who broke the last build in TFS 2010
Is there a way to query who broke the last build in TFS 2010. I know that it is possible to subscribe to the build failed event but I would like to query the TFS to get the last build and the state of the build and if it broke, who broke it. /Jimmy

Web Server sercurity from intrusion (used only for web services)
I am using a Virtual Private Server for accessing Web-Services used only on the Mobile devices, there are many entries in the access and error log, even there is nothing on the web server. I am little worried about server security. Things I have done.. 1. Installed Fail2Ban 2. rkhunter 3. using SSH login I am using Server with LAMP configuration. What other security I should use to protect against attacks ?

Regular expression for date.
I have a date format like: YYYY-MM-DD, as we all know that the months only contains numbers like 01,02,03,04,05,06,07,08,09,10,11,12. How can I actually write a regular expression that allows me to only get the correct months as well as dates. I could only do something like this... var date = /[0-9]{4}\-[0-9]{2}\-[0-9]{2}/; function checkDate(Date) { if (date.test(Date)) { alert("Valid Date"); } else { alert("Invalid Date"); } } Thus, if the date is for example, 2008-24-43. It will still return me valid date. Thanks.

Focus on text area after tab in prototype javascript library
I am trying to make a text area tab-aware and as a part of it I have written the following javascript. I am using prototype js library, document.observe("dom:loaded", function (){ $('tabawaretextarea').observe('keydown',function(e) { if(e.keyCode === 9) { // tab was pressed $('tabawaretextarea').value = $F('tabawaretextarea')+"\t"; return false; } }) }); As expected, the tabs are getting appended at the end. However, my text area loses the focuse and the HTML element next to the text area is getting focused. I believe the return false should do the magic but it does not. Any suggestions?

Learning Front end technologies (Javascript, HTML5 etc)
I'm a hardcore object oriented (mainly Java) developer with over 7 years of experience. It's fun doing back-end Java work right now, but I strongly believe in being a generalist, so I'm finally trying to learn the HTML5/CSS3/JavaScript future of the Web. However, I find JavaScript's weak typing and dynamic nature difficult to adapt to because I'm so used to strongly-typed, compiled languages with lots of compile-time error-checking and help from the IDE. Does anyone out there who has made this transition have any tips in terms of the best tools and libraries to use to make JavaScript more palatable to us old-school developers?

Guessing an unbounded integer
If I say to you: "I am thinking of a number between 0 and n, and I will tell you if your guess is high or low", then you will immediately reach for binary search. What if I remove the upper bound? i.e. I am thinking of a positive integer, and you need to guess it. One possible method would be for you to guess 2, 4, 8, ..., until you guess 2**k for some k and I say "lower". Then you can apply binary search. Is there a quicker method?

Eclipse error: This project needs to migrate WTP metadata
We started a Web Project in Eclipse 3.2 a ways back and we've since upgraded to Eclipse 3.4 but now the Project has the error: "This project needs to migrate WTP metadata" We've tried right-clicking and doing the "quick-fix" which is in fact to Migrate WTP Metadata. Unfortunately nothing happens and the error remains. We can delete that error from the Problems and everything works as it should, however, every time we re-import the project from source control, the error re-appears. Any ideas on how to permanently get rid of this error or how to ACTUALLY migrate WTP metadata?

When does EntityManager's flush() Method return?
I'm using the EntityManager to persist data into my database. public void save(X x){ entityManager.persist(x); entityManager.flush(); triggerDataChange(); } After flushing the data I call the triggerDataChange() Method to send a message to an external component which depends on the newly written data. Question: Can I rely on the flush method returning <b>after</b> the data has been written to database successfully? Thanks for your help.

Web app ports for Exchange/AD
I am developing a JBoss web app that'll be authenticating via LDAP on Active Directory and will serve as a client for MS exchange web server (through EWS api it will send e-mails). Do I have to open specific ports on the application server for communcation with exchange and AD (apart from 8080 port on which JBoss is running). Currently everything is working ok, and I didn't have any problems now since my connection to these systems don't go through firewall in my development environment. App is to be deployed on the "closed" environment. Which port should be opened on the application server machine in order to achieve communication towards AD and MS exchange, if there should any?

What is the philosophy behind using Objective-C in iOS? Why not C++?
Having involved in C++ projects for more than ten years, it is really a big question for me that why Objective-C has been used as the base programming language on iOS. Taking a look at Objective-C spec, it seems that it is more dynamic than C++ in binding variables to their types, as a result it is not more efficient than C++. Can someone tell me what the philosophy behind using this language is?

Sharepoint Changes content types when uploading files to same library
I have a library in which there are two content types: say "documents" and "drawings." For the past year, there were only files with the type "documents" in the the library but recently I have wanted to add drawings to it. When I uploaded a bunch of these drawings (~350 items) and set the default content type as "drawings," some of the files of which previously had the type "documents" switched content types to the "drawings." Just the type changed, the files are the same etc. When I added some more drawings, I noticed the same thing: mroe documents changed their content type. Has anyone else run into this issue? Thanks in advance

What is the best .WTV conversion tool?
.WTV is the new DVR-MR format for recorded TV-shows in the Vista Media Center with TV Pack 2008 installed. Since there is a bug in that TV Pack, not allowing to see the current playback posision within the MSAS COM State integration service, the only way to 'fix' the commercial skipping addin, is to convert the .WTV file into a .DVR-MR, and/or cutting out the commercial at that stage. Does anyone know of a free command-line utility that can be used for that?

SQL Server Cursor To Include the Value in Select
I have a SELECT statement returning a set of rows. From each row, I need to get a value of one column and pass it to a Stored Procedure to get a value that I would need to supply for the set of rows itself. For example: DECLARE @col1 int DECLARE @col2 int DECLARE @col3 varchar(20) DECLARE myCursor CURSOR FOR SELECT col1, col2, col3 FROM table1 WHERE.... OPEN myCursor FETCH NEXT FROM myCursor INTO @col1, @col2 WHILE @@FETH_STATUS = 0 BEGIN SET @col3 = EXEC proc_GetCol3_Value @col1, @col2 FETCH NEXT FROM myCursor INTO @col1, @col2 END CLOSE myCursor DEALLOCATE myCursor Now, based from that, I want to return the rows as retrieved by the original cursor, plus the value retrieved from the Stored procedure executed to be column 3's value. Say, the rows returned by the SQL cursor is: col1 col2 col3 1 5000 2 5000 3 2500 4 2000 And what I need is that all columns have been supplied after running the cursor and the Stored Proc and the result set should be: col1 col2 col3 1 5000 APPROVED 2 5000 REJECTED 3 2500 CANCELLED 4 2000 APPROVED Any ideas welcome. Thanks. P.S. I know that a lot would advice to simply using a JOIN statement but since the stored procedure to be executed is quite complex, making a join with the cursor SQL statement would be too complicated.

SQL Server Cursor To Include the Value in Select === I have a SELECT statement returning a set of rows. From each row, I need to get a value of one column and pass it to a Stored Procedure to get a value that I would need to supply for the set of rows itself. For example: DECLARE @col1 int DECLARE @col2 int DECLARE @col3 varchar(20) DECLARE myCursor CURSOR FOR SELECT col1, col2, col3 FROM table1 WHERE....

scheduling task in iphone
I am developing an iphone app, there's a section in it where user can declare his task and its occurence in time. I.e. recursive task. The task will only show an alert box and nothing else when its due time. Its a kind of reminder, rather than a real task scheduler. What's the best way or technology to achieve that with objective-c, particularly on iphone. I was also thinking, if not too time consuming to implement, about some kind of integration with iphone calendar. Would it be nice to have the app create its own calendar. thanks

EBJ Performance optimisation between different containers
EJB is slower than pure well optimized JDBC but here http://www.javaperformancetuning.com/news/qotm047.shtml it is said > " the simple JDBC/EJB comparison assumes that your JDBC is as > efficient as the EJB generated JDBC. That is by no means certain, as > the container vendors can have specialist developers who are expert in > producing optimal SQL." How do I know the logics of optimization between JBoss, Glassfish, TomEE ? How do I know that it is actually suited to my particular application as generic optimisation is kind of premature optimization : can I check the code generated somehow ? And can I override that optimization if necessary if yes how ?

TSQL query for Week Comparison
I have a table that has a TASK_START_DATE and TASK_FINISH_DATE Columns of type datetime I need help with a query that returns all Tasks when the Task: (date = just the date - I think I can do a conversion to the date from datetime on SQL 2008R2, it works fine) <br/> <br/>- is within 2 weeks previous of the current date or two weeks after the current date. Similarly I also need the records whose TaskEnd values are within 2 weeks previous or two weeks before I've been trying things like which would get tasks where the start date is within the two previous weeks, but I have to do the same for TASK_FINISH_DATE and I think my and's and or's are all jumbled up, any help is appreciated. Convert(Date, TASK_START_DATE) <= Convert(Date, DateAdd(ww, -2, GetDate())) Short version: How do I correctly write a query that combines all records with the TASK_START_DATE and TASK_END_DATE within two weeks in the future or past, i.e. Select Task_ID, TASK_NAME, TASK_START_DATE, TASK_END_DATE where ???

How to customize Bugzilla fields
We have one product e.g. Product1 and two groups (Group1 , Group2) having access rights as below on this product. Group1 : Shown/Shown, ENTRY, editcomponents, canconfirm, editbugs Group2: Shown/Shown, canconfirm, editbugs 1) Now we want certain Status values should be set only via specific Groups. Eg.Only Group1 can set bug Status as RESOLVED where as Group2 can not and only Group2 can set bug Status as CLOSED where as Group1 can not. 2) We want fields such as Product, Component, Importance etc. should be non-editable on show_bug.cgi page(i.e. once the bug is entered) for both the Groups. So that none of the group can modify Product, Component, Importance etc. fields once the bug is entered.

Office Addin software update options
Our team has created VSTO addin in VS 2010. We are now exploring options for updating the add-in once installed on the end user system. We are currently distributing the application using an installer. Within the office app the user gets some visual clue regarding the availability of a new version of add-in. I am exploring ways on how to actually update the add-in install directory. One option is to alert user from the application (Word, Excel) regarding the availability of new add-in including its download location. The user then downloads a new setup file manually and updates. What are the other mechanism that we can explorer. Thanks, Chandermani

How do you create a type-safe array or collection with varying types of individual elements?
I'm implementing a method in C# that takes a single argument of type `object`, e.g. `SomeMethod(object argument)`. I need to pass a collection of multiple objects of varying type to this method. I can't change the method signature because of interface restrictions. I was thinking of sending an object array, `object[] myArray = new object[2]`, but I want to strongly type each element of the array if possible. For example, I have two objects, one of type `Foo` and the other of `Bar`. I want to guarantee that `myArray[0]` is `Foo` and `myArray[1]` is `Bar`. How would I do this? Would another collection type or creating a special class make more sense?

ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
I just discovered a logical bug in my code which was causing all sorts of problems. I was inadvertently doing a **bitwise AND** instead of a **logical AND**. I changed the code from: r = mlab.csv2rec(datafile, delimiter=',', names=COL_HEADERS) mask = ((r["dt"] >= startdate) & (r["dt"] <= enddate)) selected = r[mask] TO: r = mlab.csv2rec(datafile, delimiter=',', names=COL_HEADERS) mask = ((r["dt"] >= startdate) and (r["dt"] <= enddate)) selected = r[mask] To my surprise, I got the rather cryptic error message: > ValueError: The truth value of an array with more than one element is > ambiguous. Use a.any() or a.all() Why was a similar error not emitted when I use a bitwise operation - and how do I fix this?

Is this the best way to do this?

ajax call problem
I am having problems returning the HTML from this ajax call. It works fine in FF but gives me an "null" in IE for the `alert(result.html());` Here is the code. Any ideas? Thanks!!!

How do I add CRRedist2008_x86.msi to Visual Studio Deployment Project?
I need to add CRRedist2008_x86.msi to my deployment project as it is a requirement for my app. However, I want it to run automatically. I don't want it to be just added as a file and then the user has to click on it for it to run after my app installs. Can someone guide my on how to do this? It seems like it should be very easy but for some reason I am missing something.

How to calculate the area of an SVG path c#
If anyone can help with calculating the area of an SVG path I would be very grateful. I have a function to get the total length which works really well. I've seen a javascript method that converts the path in to a polygon: http://phrogz.net/SVG/convert_path_to_polygon.xhtml Converting this to c# would be a good route as I have a function that gets the area of a polygon to a sufficient accuracy. Regards

Mixing C Structs and Objective-C Properties
I have defined an object with a CGPoint ivar and associated property as follows... @interface Sprite : NSObject { CGRect boundingBox; } @property(assign) CGRect boundingBox; When I use an instance of the Sprite class and try and update the boundingBox struct as follows... self.boundingBox.origin.x = minX; I receive a compile time error stating... > Lvalue required as left operand of > assignment Am I correct in saying that self.boundingBox will return a C struct, which isn't actually the struct held by the Sprite object but rather a copy of it? Therefore when the assignment of a new value for x fails because the struct is only a temporary copy? If this is the case will the following code work correctly (and is it the correct way to achieve what I want)? CGRect newBoundingBox = self.boundingBox; newBoundingBox.origin.x = self.boundingBox.origin.x; self.boundingBox = newBoundingBox;

I am trying to write a networking software -firewall in server, proxy?
I have question about network programming. My first question was probably about the platform, because the speed and the user friendliness is important. I decided to do it in VC++, not in .net (C#), as I want to use the firewall mechanism, though should find the common way between old windows and after vista, as I was studying about it. Honestly, I have a book titled "Network Programming for Microsoft Windows Second Edition" and another book that is about Active Directory and not an important issue here. I need to use it, too. I don't know how much that book can related to and help my software writing. My software needs to do the Bandwidth allocation job, it needs to do some packet processing and needs to control the internet usage of all clients in the server that receive internet from server, DHCP maybe or maybe through IP address, I don't know, maybe it is good or needed to write a proxy, as for filtering, too. In fact, I need guidance for writing this software, forgot to say that proxy brings a question about connectionless UDP in my mind, if that's the same way I thought: through sockets make a simple bridge. Thanks!

Is there an opensource .NET CMS that can manage banners
<br> I am rather new to the .net world and quite stuck. I am looking for a cms system to handle banners on an existing site. I don't want the cms to overtake the site, meaning I don't need a cms with an integrated banner system, I need a cms-like system that can handle banner content and just that. It's should provide a possibility for content review, content promotion, it should have an available metadata model, should allow internationalization. Any help is appreciated. <p>I was looking at <i>umbraco</i>, but it wasn't a good fit for the site I am working on. Perhaps a good banner system, that does have a cms like capabilities.

Convert a 4 char string into int32
Is there a fast way to convert 4 chars into a 32bit int? I know i can loop through it like : string key = "ABCD"; int val = 0; for (int i = 0; i < 4; i++) { int b = (int)key[i] * (int)Math.Pow(256, i); val += b; } // val = 1145258561 I would like something lower level, I know the chars are stored as bytes. I don't mind if its unsafe code because I am basically trying to write a 4 char string to an integer pointer location.

MVC Abstract Base Controller Override parameter type for modelbinding
For simplicity's sake, lets say I have the following Abstract Base Controller Class: public abstract class RESTController : Controller { public abstract JsonResult List(); public abstract JsonResult Get(Guid id); public abstract JsonResult Create(object obj); public abstract JsonResult Update(object obj); public abstract JsonResult Delete(Guid Id); } For the Create & Update methods, I not only want to override the Method, but also the type of the parameter. Typically I would use generics like so: public abstract JsonResult Create<T>(T obj); However this is an MVC action, and there is no way to specify type parameters. What are my options? If I leave it as `(object obj)` will the MVC model binder work correctly? var model = obj as MyViewModel; This isn't very clean in any case. Any help would be appreciated.

creating a code editor with visual studio 2010 using C# === I am trying to make a code editor winforms application for features like syntax highlighting,and many more code editing features using visual studio 2010.I used **scintillaNet** with my visual studio ultimate version with net 4.0 framework for my winform application. but after adding the tool in my toolbox the scintilla.net shows many errors and dragging it onto my form becomes impossible..plz help. I have also tried **actipro Syantx editor**,its pretty good but the evaluation version comes for 15 days and its not free or open source like scintilla.net.. i also tried **editor.net** from Qwhale,it is very good but could not create a new parser for **vhdl** language as none of the text editors have vhdl as one of their sample languages.it supported around 20 language parsers but none for VHDL. plzz help with other alternatives or solns for these..!!!

How to execute .sql file using powershell?
I am having .sql file. I am trying to pass connection string details through powershell script and invoke the .sql file. I was searching and come up with some cmdlet related to Invoke-sqlcmd. While i was trying to find the module which is corresponding to SQL , i did not find any one in my machine. Should i install any thing in my machine (the machine already has ssms 2008 R2) to get the modules? or is there any easy way to execute .sql files using powershell?

JSON string is treated as a literal string in loop
I suspect this is an easy problem, but I am a bit new to js and can't find the solution. Thanks in advance. Basically, when I pass a JSON string to a function and then attempt to iterate through the passed variable, it treats it like a literal string rather than an array. With this function: function build_codes_long(codes) { var codes_long_text = ""; for(var i =0;i < codes.length-1;i++) { var code = codes[i]; codes_long_text += "<p>" + code['id'] + " = " + code['del'] + "</p>"; } return codes_long_text; } When I pass a JSON string to it like: [{"id":"1","del":"0","clip":"1"},{"id":"2","del":"0","clip":"1"}] It evaluates each character in the string, rather than each item in the array. So it loops 65 times instead of 2, returning something like: undefined = undefined I understand the problem with the returned values; it's the treating the array like a literal string I don't understand. Thanks!

$.when not waiting for ajax return
I have this code $('#mySelect').change(function() { $.get( "test.php", function(data) { alert('test1'); }, ); }); I need to fire the event change of #mySelect, and wait for the answer of the ajax to perform a other task. But when I try $.when($('#mySelect').change()).done(function() { alert('test2'); }); It only wait for the change is finish, and the ajax sended, not received. So I have the alert 'test2' before 'test1' How can I make $.when wait for everything inside the even to be finish?

Javascript Search
I would like to add a search on name of people on my website. The list of friends is already displayed on the page. I love the way Facebook is doing this where you start typing a name and Facebook only displays your friends that match the query. http://cl.ly/2t2V0v2Q103X2G1V080R and http://cl.ly/0R1j0B2n1s3y413i0a34 Any ideas on implementing this ?

Powershell: Args/params not being populated

I run it as `.\csvtosql.ps1 mycsv.csv dbo.MyTable` (from powershell shell), and get Args: 0 Get-Content : Cannot bind argument to parameter 'Path' because it is an empty s tring.

What Could Cause time.sleep() to be Horrifically Inaccurate?
I have a program that takes measurements in a user-specified interval. In order to keep it on the desired interval in spite of scheduling shenanigans, I keep track of when the program started and the time when each interval should end so that I can sleep for however long the program needs to reach the next interval. This system works totally fine with my laptop running Vista and another computer running XP, but when I copy/paste the program on a third computer running XP it sleeps for anywhere from 20-40 seconds when given a 10 second interval! This is especially strange since I've set it so that if it's missed an interval it should attempt to take another measurement immediately, but I'm not seeing anything to indicate that that is happening. I've reinstalled python 2.7.2 but the program still has the exact same problem. I've checked all the processes and services on the problem computer and there's nothing out of the ordinary and nothing using up any system resources. Is there any reason why time.sleep would sleep for so long? Here's the code segment in question. In my program it was running independently in three threads. cycles is an int counter initialized to zero, self.delay is a float holding the user-specified delay, in this case 10.0 seconds. cycles += 1 currentTime = time.clock() wakeUp = startTime + cycles * self.delay if currentTime > wakeUp: #we overslept continue else: #not guaranteed to sleep for the exact specified amount of time time.sleep(float(wakeUp - currentTime)) finalTime = time.clock() print "sleep(" + str(wakeUp - currentTime) + ") lasted " + str(finalTime - currentTime) +" seconds" And here's the output it gave (again, this is from three threads running the same code at once): sleep(9.79808763972) lasted 2.23244022605 seconds sleep(9.85392503634) lasted 2.28918191569 seconds sleep(9.85480072929) lasted 2.28966006466 seconds sleep(17.4051347451) lasted 3.53031012481 secondssleep(17.460965924) lasted 3.57 352359781 seconds sleep(17.4618652549) lasted 3.57801161345 seconds sleep(23.7643461506) lasted 3.95732551752 seconds sleep(23.6929753521) lasted 3.89900929026 seconds sleep(23.7410070723) lasted 3.95309855646 seconds sleep(29.6151041176) lasted 4.11169123853 seconds sleep(29.7488017693) lasted 4.24533422385 seconds sleep(29.6727458824) lasted 4.163745103 seconds

WPF Changing Controls within a data template?
so now that I can access controls hidden within nested datatemplates, it seems that I cannot change their values. For instance I have the code (granted to me graciously by a Stack overflow member) <Grid Name="mainGrid"> <Grid.Resources> <DataTemplate x:Key="frontTemplate" > <StackPanel x:Name="noWork"> <Image Source="Images/1.png" Stretch="Fill" Width="72" Height="96" x:Name="FrontFace" HorizontalAlignment="Left" VerticalAlignment="Top"></Image> </StackPanel> </DataTemplate> <DataTemplate x:Key="flipItemTemplate"> <Grid Width="200" Height="200"> <Border x:Name="frontHost" Background="Transparent"> <ContentPresenter Name="contentPresenter" Content="{Binding}" ContentTemplate="{StaticResource frontTemplate}" /> </Border> </Grid> </DataTemplate> </Grid.Resources> </Grid> And although I can get TO the image in that second template (frontFace) I can't get the source to change. I can get a new bitmap, and load it without error, but the image does not change. If I put an image control in the XAML outside of the datatemplate and load it with my bitmap code there, it works fine. This leads me to believe that the template can't redraw itself after its been applied... BUT I can't get access to its internal elements until its been applied... so how in the heck do I dynamically set up elements in a template before its been applied?

How to access a xml node with attributes and namespace using selectsinglenode()

Example: DataTable myDt = new DataTable(); if (myDt != null && myDt.Rows.Count > 0) { //do some stuff with myDt } Which statement does the runtime evaluate first - myDt != null or: myDt.Rows.Count > 0 ?

Any reasons why 64 bit process would be twice as slow?
So I have two versions of the same program, one configured as for 64 bit and the other as 32. I am running it on a macpro with 2xquad core intel and 14 GB RAM. After running a trial, I realised that the 64 bit version took twice as long as its 32 bit counterpart. Notes - my OSx is a bit old, 10.5.8, which i understand isnt the best place to be running 64 bit processes, but still it shouldnt take longer?! - also I ran them at the same time, and each of them only used 1 processor. not sure if that makes a dif. -my reason for wanting to run it in 64 is that when I tried the real, very large job i kept getting memory allocation errors, which i still for the life of me cant figure out Does this make sense to anyone? sorry if something sounds incorrect, im a biologist, go easy on me!

Do I need to do some special setting for Virtual Legacy Wire in Linux kernel?
In my x86 main board, I connect some special interrupt sources (including NMI) to the south bridge chip. In the datasheet of the chip, it says that these interrupts are sent to CPU via virtual legacy wire (VLW). I don't know VLW well, and I don't know whether it is transparent for software developers. Currently I can't capture the interrupts in Linux kernel. So my question is that do I need to do some special settings for VLW in kernel? In my previous hardware and code, I used IOAPIC to handle the similar interrupts and it worked well.

An Attempt to solve LOH Fragmentation Problems (StringBuilder + RegEx)
I was having some serious LOH Fragmentation problems with processing large strings and especially running RegEx matches on them. Looked around a lot but couldn't find a solution, here is my attempt solve this problem in a fairly generic way but with some obvious limitations. Since I haven't seen this advice anywhere and everyone is whining about LOH Fragmentation I wanted to share the code to confirm that my design and assumptions are correct. **Theory:** 1. Create a shared massive StringBuilder (this is to store the big strings that read from we read from streams) - `new StringBuilder(ChunkSize * 5);` 2. Create a massive String (has to be bigger than max. accepted size), should be initialized with empty space. - new string(' ', ChunkSize * 10); 3. Pin string object to memory so GC will not mess with it. `GCHandle.Alloc(pinnedText, GCHandleType.Pinned)`. Even though LOH objects are normally pinned this seems to improve the performance. Maybe because of `unsafe` code 4. Read stream into shared StringBuilder and then unsafe copy it to pinnedText by using indexers 5. Pass the pinnedText to RegEx With this implementation the code below works just like there is no LOH allocation. If I switch to `new string(' ')` allocations instead of using a static `StringBuilder` or use `StringBuilder.ToString()` code can allocate **300% less memory** before crashing with `outofmemory exception` I also confirmed the results with a memory profiler, that there is no LOH fragmentation in this implementation. I still don't understand why RegEx doesn't cause any unexpected problems. I also tested with different and expensive RegEx patterns and results are same, no fragmentation. **Code:** http://pastebin.com/ZuuBUXk3 using System; using System.Collections.Generic; using System.Runtime.InteropServices; using System.Text; using System.Text.RegularExpressions; namespace LOH_RegEx { internal class Program { private static List<string> storage = new List<string>(); private const int ChunkSize = 100000; private static StringBuilder _sb = new StringBuilder(ChunkSize * 5); private static void Main(string[] args) { var pinnedText = new string(' ', ChunkSize * 10); var sourceCodePin = GCHandle.Alloc(pinnedText, GCHandleType.Pinned); var rgx = new Regex("A", RegexOptions.CultureInvariant | RegexOptions.Compiled); try { for (var i = 0; i < 30000; i++) { //Simulate that we read data from stream to SB UpdateSB(i); CopyInto(pinnedText); var rgxMatch = rgx.Match(pinnedText); if (!rgxMatch.Success) { Console.WriteLine("RegEx failed!"); Console.ReadLine(); } //Extra buffer to fragment LoH storage.Add(new string('z', 50000)); if ((i%100) == 0) { Console.Write(i + ","); } } } catch (Exception ex) { Console.WriteLine(ex.ToString()); Console.WriteLine("OOM Crash!"); Console.ReadLine(); } } private static unsafe void CopyInto(string text) { fixed (char* pChar = text) { int i; for (i = 0; i < _sb.Length; i++) { pChar[i] = _sb[i]; } pChar[i + 1] = '\0'; } } private static void UpdateSB(int extraSize) { _sb.Remove(0,_sb.Length); var rnd = new Random(); for (var i = 0; i < ChunkSize + extraSize; i++) { _sb.Append((char)rnd.Next(60, 80)); } } } }

Grails springSecurityService.getCurrentUser() is Null when using custom AuthenticationProvider
One controller in my app needs to be accessible by users authenticated against an external database. I have set up a custom user object, class CustomUserDetails extends GrailsUser { final String externalId CustomUserDetails(String username, String password, boolean enabled, boolean accountNonExpired, boolean credentialsNonExpired, boolean accountNonLocked, Collection<GrantedAuthority> authorities, long id, String externalId) { super(username, password, enabled, accountNonExpired, credentialsNonExpired, accountNonLocked, authorities, id) this.externalId = externalId } } and a custom AuthenticationProvider class CustomAuthenticationProvider implements AuthenticationProvider { def springSecurityService Authentication authenticate(Authentication customAuth) { /* Do stuff to validate the user's credentials here */ def userDetails = new CustomUserDetails(customAuth.getPrincipal(), customAuth.getCredentials(), true, true, true, true, [new GrantedAuthorityImpl('ROLE_SPECIAL_USER')], 9999999, "externalDatabaseIdString") def token = new UsernamePasswordAuthenticationToken(userDetails, null, userDetails.authorities) return token } boolean supports(Class authentication) { return true } } I've made entries in Config.groovy to add this to the springsecurity.providerNames list, and added the following to conf/spring/resources.groovy beans = { customAuthenticationProvider(info.proadvisors.auth.CustomAuthenticationProvider){ bean -> bean.autowire = "byName" } userDetailsService(org.codehaus.groovy.grails.plugins.springsecurity.GormUserDetailsService){ bean -> bean.autowire = "byName" } } Here's the problem - in my controller, springSecurityService is being injected but springSecurityService.getCurrentUser() is null, and returns a null pointer exception when I try to access the externalId property that should be on the authenticated user object. If, in my CustomAuthenticationProvider, instead of creating an instance of CustomUserDetails I use GormUserDetailsService to give me a GrailsUser object and use that to build the token, the controller works properly and getCurrentUser() works. Any ideas on why this isn't working?

Ajax http / https problem
i would like to ask you for workaround on following problem. My site can use http and https protocol, it doesnt affect the content. My site uses jquery ajax calls, which fills some areas on page, too. Now, i would like to do all ajax calls by https protocol. (please dont ask me why :)) When i am on page with https protocol, all is correct. Ajaxes are working. When im on page with http protocol, i got javascript error: Access to restricted URI denied I know that this is cross domain problem (in fact its not, its cross protocol problem), and i know, that i should use same protocol in ajax call as protocol on current page. Still i want to have all ajax calls starting with https, and call them from page starting with http. is there any workaround to achieve this(some json/proxy solution?), or is it simply imposible?

And the rest of the mp3 is just blank. The audio tag thinks it's still reading the file, but there is no sound. This is how I'm sending the mp3 file from php: if (file_exists($filename)) { header("Content-Transfer-Encoding: binary"); header("Content-Type: audio/mpeg"); header('Content-length: ' . filesize($filename)); header('Content-Disposition: inline; filename="' . $filename .

XMLSpy Validator === What XML validator does XMLspy uses? I am running into an issue that I can validate an XML file against the schema using Oxygen but yet it is not valid when I use XMLSpy! does anyone has any general thoughts regarding this? Thanks a lot :)

Should I consider switching to Silverlight from WPF?
I have been using WPF for a new project which is far from done. It's a hobby project and a very useful one. I'd like to have cross-platform compatibility (i.e. Linux + Mac + Windows), but Windows is the primary target. I'm pretty good with web languages and C# and Erlang, but C/C++ are not among them and I hate Java. So it was a natural move to choose WPF for me. However, after reading numerous sources like http://www.mono-project.com/WPF: > At this point, we strongly suggest that users interested in WPF adopt > Silverlight instead as it can now be used outside of the browser and > offers a rich set of cross platform APIs and features. I'm starting to wonder if I should port my app to Silverlight and use it instead. A couple of facts: - My application is pure desktop application and meant to be so. It needs lower level access to system resources (but not that low that .NET wouldn't be enough). - I'd like to have the three platforms support, but Windows is the primary concern. - I'd prefer C# and .NET and something equivalent to WPF where the UI is declarative, separated from code in a clean way and allows for rich user interfaces. I've heard Silverlight works in Mac already, and support for Linux is possible via Moonlight. **Should I consider switching to Silverlight from WPF and what problems may arise?**
