• IIS7 or .Net 301 Redirects from 1 domain to another

  - by RandomBen

  I have 2 domains. For the question, I will call them www.old.com and www.new.com. Both urls are pointing to the same IIS7 Site instance. I need to it up so that when someone goes to www.old.com they get a 301 redirect to www.new.com. The tricky part is I am using URL rewrites for pages within the site. So www.old.com/About.aspx redirects to www.new.com/About. To get that to work with IIS7 URL rewrite rules, it also means that www.new.com/About.aspx redirects to www.new.com/About. That is fine and is not a big deal. My issue is how do I redirect the main domain without losing the URL Rewrites from the sub pages? I don't care if I use a module within IIS7 or if I need to do it in .NET code.

• Ubuntu Eye-Infinity across 3 displays

  - by Peter G Mac.

  So I purchased a computer recently and have been trying to customise the display. Radeon 6800 series Ubuntu 10.10 I have three 22inch 1080P lcd monitors that are mounted together. Everything is working smooth. How do I get the 'big-desktop' display where I have one enormous display across all monitors? Linux - ATI Catalyst Control Center 11.2 does not give me an option to 'group' my profiles like the pictures on their site show with Windows. I have been searching all over for help. Much Obliged, -Peter

• How can avoid at this line an OverflowException?

  - by SoMoS

  LastInput.time is an Integer and m_idleTime is an Integer too. This line sometimes generates an Overflow exception, I think that this happens when both values are big negative values. (Environment.TickCount - lastInput.time) > m_idleTime How can I avoid that? With casting? (CType(Environment.TickCount,Long) - CType(lastInput.time,Long)) > m_idleTime Or maybe with this cast? CType((Environment.TickCount - lastInput.time),Long) > m_idleTime Thanks in advance.

• P/Invoke a Function Passed a StringBuilder

  - by andrew

  in a C# file i have a class Archiver { [DllImport("Archiver.dll")] public static extern void archive(string data, StringBuilder response); } string data is an input, and StringBuilder response is where the function writes something the archive function prototype (written in C) looks like this: void archive(char * dataChr, char * outChr); and it receives a string in dataChr, and then does a strcpy(outChr,"some big text"); from C# i call it something like this: string message = "some text here"; StringBuilder response = new StringBuilder(10000); Archiver.archive(message,response); this works, but the problem, as you might see is that i give a value to the StringBuilder size, but the archive function might give back a (way) larger text than the size i've given to my StringBuilder. any way to fix this?

• Is it magic or what ??

  - by STRIDER

  I am writing a big C code... The code includes recursive bactracking function named Branch() that is called so much... My goal is to write the fastest code to get the best running time...

• I have many processes in my usecase , is this normal ?

  - by BugKiller

  Hi, I'm working now on a big system that consists of many subsystems , each subsystem depends on the other. I wrote a usecase for this system , but I note that I have many processes in my usecase ( more than 40 processes ! ) . it looks like this : Group subsystem: add Group. remove Group. join to Group. upload file. create poll. remove file. remove poll. write post/topic close post. edit post. .... Messages Centers send message view inbox read message. and so on .. each user interacts with these processes . How can I reduce the number of these processes? Is it possible to divide the usecase processes into many pages?

• Open source configuration framework for ASP.NET - does one exist?

  - by Jon

  We currently have an old product written in classic asp and are about to re-write parts in ASP.NET. One big problem is that much of the cutomer-specifics within the system are hard coded. We want to split this out for specific customers by storing data in the database. Is there a quick an easy open source framework which allows me to set up some quick tables and simple UIs to allow me to change configuration items? We have 6-7 modules, and it would be nice to have the ability to have system admins gain access to a configuration area where they can set-up settings in a tabbed UI format, settings could also be set-up to allow dropdown, fields, numbers etc. The items could then be accessed via classes in C#/vb for use within the operational parts of the system. If not, I'm suprised and it might even be a good basis for a new open source project.

• MySQL, how can I SELECT WHERE one field value doesn't occurs in another?

  - by Jules

  I'm trying to do a search on my test server, speed isn't so important. I want to find if a phrase, the whole contents of one field, occurs in any part (as a whole) doesn't occur in another field. Heres my current query which finds if the phrase does occur SELECT pads.padid, pads.programname, keywords.word FROM Pads JOIN keywords ON Pads.Padid = keywords.Padid WHERE pads.Programname = keywords.word AND RemoveMeDate = '2001-01-01 00:00:00' My problem is that the field word contains other words too. I need to produce a count of where there isn't a keywords record with keywords.word equal to pads.programname ? EDIT: So if I have these records Pads: PadID=3 ProgramName=my prog PadID=4 ProgramName=Bad prog PadID=5 ProgramName=Good prog PadID=6 ProgramName=other prog Keywords: PadID=3 word=fox prog PadID=3 word=pig prog PadID=4 word=big prog PadID=4 word=nice prog PadID=5 word=fox prog PadID=6 word=bad prog PadID=6 word=fox prog The query I want would retun a count of 3 and record 6 has bad prog

• How do you make an in-place construction of a struct casted to array compile in Visual C++ 2008?

  - by Irwin1138

  I'm working with quite a big codebase which compiles fine in linux but vc++ 2008 spits errors. The problem code goes like this: Declaration: typedef float vec_t; typedef vec_t vec2_t[2]; The codebase is littered with in-place construction like this one: (vec2_t){0, divs} Or more complex: (vec2_t){ 1/(float)Vid_GetScreenW(), 1/(float)Vid_GetScreenH()} As far as I know, this code constructs a struct, then converts it to an array and passes the address to the function. I personally never used in-place construction like this so I have no clue how to make this one work. I don't maintain the linux build, only the windows one. And I can't get it to compile. Is there some switch, some macro to make vc++ compile it? Maybe there is a similar nifty way to construct those arrays and pass them to the functions in-place that compiles just fine in vc++?

• What are good hosting companies for PHP 5.3 Mysql / CouchDb / MongoDB Dev ( Lithium / CakePHP Framew

  - by Abba Bryant

  I am looking for a quality reliable host for some lithium development. I don't mind a shared platform as long as I have some ssh access. I require php 5.3.x, Mysql 5.x, and the usual imageMagick etc. Non-relational DB support up front would be nice but if they let me set one up myself I would be okay with doing it. I don't need a lot in the way of control panel tools. Good ones are appreciated but bad ones I would prefer not to even deal with. I don't anticipate needing much in the way of email but mail support would be nice to have. Cost isn't a big issue. I don't want to pay an arm and a leg but don't mind paying for what I need. Good support and decent uptime would be nice but I don't need an SLO or anything.

• Are there cross-platform tools to write XSS attacks directly to the database?

  - by Joachim Sauer

  I've recently found this blog entry on a tool that writes XSS attacks directly to the database. It looks like a terribly good way to scan an application for weaknesses in my applications. I've tried to run it on Mono, since my development platform is Linux. Unfortunately it crashes with a System.ArgumentNullException deep inside Microsoft.Practices.EnterpriseLibrary and I seem to be unable to find sufficient information about the software (it seems to be a single-shot project, with no homepage and no further development). Is anyone aware of a similar tool? Preferably it should be: cross-platform (Java, Python, .NET/Mono, even cross-platform C is ok) open source (I really like being able to audit my security tools) able to talk to a wide range of DB products (the big ones are most important: MySQL, Oracle, SQL Server, ...)

• FFmpeg bitrate issue.

  - by user329840

  I'm dealing with a very big issue about bit rate , ffmpeg provide the -b option for the bit rate and for adjustment it provide -minrate and -maxrate, -bufsize but it don't work proper. If i'm giving 256kbps at -b option , when the trans-coding finishes , it provide the 380kbps. How can we achieve the constant bit rate using ffmpeg. If their is +-10Kb it's adjustable. but the video bit rate always exceed by 50-100 kbps. I'm using following command ffmpeg -i "demo.avs" -vcodec libx264 -s 320x240 -aspect 4:3 -r 15 -b 256kb \ -minrate 200kb -maxrate 280kb -bufsize 256kb -acodec libmp3lame -ac 2 \ -ar 22050 -ab 64kb -y "output.mp4" When trans-coding is done, the Media Info show overall bit rate 440kb (it should be 320kb). Is their something wrong in the command. Or i have to use some other parameter? Plz provide your suggestion its very important.

• Should I use DTOs as my data models in MVVM?

  - by JonC

  I'm currently working on what will be my first real foray into using MVVM and have been reading various articles on how best to implement it. My current thoughts are to use my data models effectively as data transfer objects, make them serializable and have them exist on both the client and server sides. It seems like a logical step given that both object types are really just collections of property getters and setters and another layer in between seems like complete overkill. Obviously there would be issues with INotifyPropertyChanged not working correctly on the server side as there is no ViewModel to which to communicate, but as long as we are careful about constructing our proper domain model objects from data models in the service layer and not dealing the the data models on the server side I don't think it should be a big issue. I haven't found too much info about this approach in my reading, so I would like to know if this is a pretty standard thing, is this just assumed to be the de facto way of doing MVVM in a multi-tier environment? If I've got completely the wrong idea about things then thoughts on other approaches would be appreciated too.

• logrotate compress files after the postrotate script

  - by Thomas

  I have an application generating a really heavy big log file every days (~800MB a day), thus I need to compress them but since the compression takes time, I want that logrotate compress the file after reloading/sending HUP signal to the application. /var/log/myapp.log { rotate 7 size 500M compress weekly postrotate /bin/kill -HUP `cat /var/run/myapp.pid 2>/dev/null` 2>/dev/null || true endscript } Is it already the case that the compression takes place after the postrotate (which would be counter-intuitive)? If not Can anyone tell me if it's possible to do that without an extra command script (an option or some trick)? Thanks Thomas

• Garbage collection - manually wiping EVERYTHING!

  - by Glycerine

  I have been building a game for a while (nearly done) - But the game needs a replay button and its a big task. I know the GC is dreadful in flash, but I wanted to know if there is a way to wipe EVERYTHING as if the flash app has just begun. Clearing memory, game data - I haven't to worry about game loading as its not really heavy on data. Everything pretty much lives in a DataModel - but I fear if I just clear the all variables, I'll have pockets of orphaned memory. Any forwarding idea would be great. cheers guys.

• Avoiding Nested Queries

  - by Midhat

  How Important is it to avoid nested queries. I have always learnt to avoid them like a plague. But they are the most natural thing to me. When I am designing a query, the first thing I write is a nested query. Then I convert it to joins, which sometimes takes a lot of time to get right. And rarely gives a big performance improvement (sometimes it does) So are they really so bad. Is there a way to use nested queries without temp tables and filesort

• Where can I find a large body of *Python3* source code?

  - by Ira Baxter

  I'm testing a Python parser. I have Python 2.6/2.7 firmly under control, and some good (large) code samples on which I've tested it. I'm interested in testing my Python3 variant. I've been to various Python open source web sites (e.g., http://pythonsource.com/), which list lots of packages, but they are pretty unclear as whether these are Python 2.x vs 3.x source files. The several samples that I downloaded all turned out to be Python 2.x. Where can I find a number of large Python 3 software source codes? I don't really want 1000 little separate Python3 files; I prefer big applications.

• Simple XML parsing with Google Picasa API and JQuery

  - by zeedog

  I'm starting to look into Google's Picasa API for photo data, which provides you with a big XML file with info about albums and photos. I'm doing some quick and dirty tests to parse the XML file (which is saved locally to my hard drive for now) with JQuery and pull out the album id's, which are stored as "gphoto:id" tags, and display them in a div: $(document).ready(function() { $.get( 'albums.xml', function(data) { $(data).find('entry').each(function() { var albumId = $(this).children('gphoto:id').text(); $('#photos').append(albumId + '<br />'); }) }) }) I'm getting the following error in the console: jquery.js:3321 - Uncaught Syntax error, unrecognized expression: Syntax error, unrecognized expression: id This will work with other tags in the XML file (such as title, author, updated, etc.), but I'm trying to understand what's going on here. Does it have to do with the colon in "gphoto:id", somehow?

• How are deleted and renamed/moved files handled when merging a feature branch with trunk and reinteg

  - by Michael Repucci

  I've got a big-ish project that needs a lot of work on a new feature, so I planned on using a branch to do this work. I haven't had to do this before, and I just wanted to get assurance from an experienced Subversion user that things "should" work smoothly. What I'm especially concerned with is how well Subversion handles deleted, renamed/moved files between a branch and the trunk. That is, if multiple files are deleted or renamed/moved in the branch, but those files continue to be used and receive changes in the trunk, will merges with the trunk still proceed without a hitch (reworking the branch, of course, as necessary)? Also, when I then reintegrate the branch with the trunk, if the files differ greatly in name (or existence) between the trunk and branch, will the reintegration be difficult? Will the files deleted (moved) in the branch now be deleted (moved) in the trunk, or will files linger and conflicts emerge? The SVN book didn't clear up these questions for me, so your experience would be greatly appreciated. Thank you!

• cheap way to scale a rails application

  - by VP

  I have an application, that is becoming big, but until now, its not giving me a good revenue. That means, short money to re-invest on that. In this scenario, i found a way to make a "cheap distributed rails" deployment. I've got 4 VPS. All of them are in the same physical server. I added a load balance server running HAproxy in one dedicated VPS. There i pointed my virtual ip address where my domain name is associated. Behind this HAproxy i have more two VPS running my rails APP, passenger and memcache. Both apps servers are looking to the same database server, my 4th VPS. So with $44/month, i mounted a distributed environment. It won't be my final choice, but now, that the budget is short, is that a good way to deploy a rails application? Any pros or cons? It worth my $44/month?

• URL encoded POST bad practice?

  - by StackedCrooked

  I am (just for fun) trying to implement a High Score web-service. I would like it be compatible with REST principles. I want to be able to add a new highscore using url parameters like this http://mydomain.com/hs/add&name=John&score=987. According to REST this must be done using a POST request. Which leads to empty POST request with all data contained in the URL parameters. Would this be considered a bad practice? Update Security is currently not a big concern.

• Database caching on a shared host

  - by tau

  Anyone have any ideas how to increase MySQL performance on a shared host? My question has less to do with overall database performance and more to do with simply retrieving user-submitted data. Currently my database will create caches at timed intervals, and then the PHP will selectively access the static files it needs. This has given me a noticeable performance boost, but I am worried about a time in which I have so much data that having to read in big files in PHP will actually be slower. I am just looking for ideas for shared hosting solutions; I am not going to get my own server anytime soon. Thanks!

• Chaning coding style due to Android GC performance, how far is too far?

  - by Benju

  I keep hearing that Android applications should try to limit the number of objects created in order to reduce the workload on the garbage collector. It makes sense that you may not want to created massive numbers of objects to track on a limited memory footprint, for example on a traditional server application created 100,000 objects within a few seconds would not be unheard of. The problem is how far should I take this? I've seen tons of examples of Android applications relying on static state in order supposedly "speed things up". Does increasing the number of instances that need to be garbage collected from dozens to hundreds really make that big of a difference? I can imagine changing my coding style to now created hundreds of thousands of objects like you might have on a full-blown Java-EE server but relying on a bunch of static state to (supposedly) reduce the number of objects to be garbage collected seems odd. How much is it really necessary to change your coding style in order to create performance Android apps?
