• Configuring 32-Bit ASP.NET Application on a 64-Bit IIS Server

  - by Tim

  Hello, I’m trying to install a 32-bit ASP.NET application onto a 64-bit IIS server running on Windows Server 2008. This is a clean installation of the operating system with no other applications installed. As a prerequisite for our installation, we run the 32-bit version of aspnet_regiis –i It fails with the following message: The error indicates that IIS is not installed on the machine. Please install IIS before using this tool. Additionally: IIS is definitely installed. The 64 bit version of aspnet_regiis runs cleanly without warnings. “Enable 32 bit applications” is set to True in the DefaultAppPool’s Advanced Settings. The IIS Metabase and IIS 6 configuration compatibility” component is installed. We have a test VM where this error occurs as well as test VM where both the 32 bit and 64 bit versions of aspnet_regiis run without errors. We've had no luck distinguishing the differences between the two test VMs. We have struggled with this issue for several days to no avail. Any suggestions would be greatly appreciated!

• What is the suggested approach to Syncing/Backing up/Restoring from SQL Server 2008 to SQL Server 20

  - by Eoin Campbell

  I only have SQL Server 2008 (Dev Edition) on my development machine I only have SQL Server 2005 available with my hosting company (and I don't have direct connection access to this database) I'm just wondering what the best approach is for: Getting the initlal DB Structure & Data into production. And keeping any structural changes/data changes in sync in future. As far as I can see... Replication - not an option cos I can't connect to the production DB. Restoring a backup - not an option because as far as I can see, you cannot export a DB from 2008 that is restorable in 2005 (even with the 2008 DB set in 2005 compatibility mode) and it wouldn't make sense to be restoring production over the top of my dev version anyway. Dump all the scripts from my 2008 Database, Revert my Dev to machine from 2008 - 2005, and recreate the database from the scripts, then just use backup & restore to get the initial DB into production, then run scripts through the web panel from that point onwards Dump all the scripts from my 2008 Database and generate the entire 2005 db from scripts in production. then run scripts through the web panel from that point onwards With the last 2 options, I'd probably need to script all the data inserts as well using some tool (which I presume exists on the web) Are there any other possibile solutions that I'm not considering.

• How to open a document using an application launched via NSTask?

  - by zneak

  Hello world, I've grown tired of the built-in open Mac OS X command, mostly because it runs programs with your actual user ID instead of the effective user ID; this results in the fact sudo open Foo opens Foo with its associated application with your account instead of the root account, and it annoys me. So I decided to make some kind of replacement. So far I've been successful: I can open any program under the open -a or open -b fashion, and support optionally waiting. I'm using NSTask for that purpose. However, I'd like to be able to open documents too. As far as I can see, you need to use NSWorkspace for that, but using NSWorkspace to launch programs results in them being launched with your account's credentials instead of your command line program's credentials. Which is precisely what the default open tool does, and precisely what I don't want. So, how can I have a program request that another program opens a document without using NSWorkspace? From the NSTask object, I can have the process ID, but that's about it.

• To have an Integer pointing to 3 ordered lists in Java

  - by Masi

  Which datastructure would you use in the place of X to have efficient merges, sorts and additions as described below? #1 Possible solution: one HashMap to X -datastructure Having a HashMap pointing from fileID to some datastructure linking word, wordCount and wordID may be a good solution. However, I have not found a way to implement it. I am not allowed to use Postgres or any similar tool to keep my data neutralized. I want to have efficient merges, sorts and additions according to fileID, wordID or wordCount for the type below. I have the type Words which has th field fileID that points to a list of words and to relating pieces of information: The Type class Words =================================== fileID: int [list of words] : ArrayList [list of wordCounts] : ArrayList [list of wordIDs] : ArrayList Example of the data in fileID word wordCount wordID instance1 of words 1 He 123 1111 1 llo 321 2 instance2 of words 2 Van 213 666 2 cou 777 932 Example of needed merge fileID wordID fileID wordID 1 2 1 3 wordID=2 2 2 ========> 1 2 2 3 2 2 I cannot see any usage of set-operations such as intersections here because order is needed. Having about three HashMaps makes sorting difficult: from word to wordID in a given fileID from wordID to fileID from wordID to wordCount in a given fileID

• Why do people have to use multiple versions of jQuery in the same page?

  - by reprogrammer

  I have noticed that sometimes people have to use multiple versions of jQuery in the same page (See question 1 and question 2). I assume people have to carry old versions of jQuery because some pieces of their code is based on an older version of jQuery. Obviously, this approach causes inefficiency. The ideal solution is to refactor the old code to use the newer jQuery API. I wonder if there are tools that automate the process of upgrading a piece of code to use a newer version of jQuery. I've never written programs in in either Javascript or jQuery. So, I'd like to hear from programmers experienced in these language about their opinion on this issue. In particular, I'd like to know the following. How much of problem it is to have to load multiple versions of jQuery? Have you ever had to load multiple versions of any other library in the same page? Do you know of any refactoring tools that helps you migrate your code to use the updated API? Do you think such a refactoring tool is useful? Are you willing to use it?

• open source business intelligence solutions

  - by opensas

  which open source business intelligence solution would you recommend? All I need is to build some cubes and let the end user play with dimensions, filter data, sort, etc, and once it's done being able to export it to excel... I'd like the solution to be as simple and easy on resources as possible, and also I'd like it to be as much open source as possible, by the way. I've heard that many solutions available do have many restrictions when it comes to there community version. I'd like to ear your advices and the pros/cons of each alternative, to help me choose the right tool, and if you could point me to some basic demo and tutorial to get started. thanks a lot ps: I'm using sql server databases, they aren't huge databases (in general less than a million records) and I doesn't necessarily have to work on "live" data... ps: some useful links: http://en.wikipedia.org/wiki/Business_intelligence_tools#Open_source_free_products http://www.manageability.org/blog/stuff/open-source-java-business-intelligence http://www.jaspersoft.com/jasperanalysis http://community.pentaho.com/projects/bi_platform/ http://community.pentaho.com/faq/platform_licensing.php http://www.eclipse.org/birt/phoenix/ http://www.spagoworld.org/xwiki/bin/view/SpagoWorld/ http://docs.google.com/viewer?a=v&q=cache:vhsqMQXwCUkJ:www.ow2.org/xwiki/bin/download/Activities/EuropeLocalChapterWebinars/ELCWebinarOSBI.pdf+open+source+business+intelligence&hl=en&pid=bl&srcid=ADGEESgpJJ2MqaKprJQOF2jX2UXCZQjg_asv8d7EVYtq0Vma-e-tR1tFxS-I0SOW0IhJC5acYc94rkDOrgP1WckCp_vk4qhKqR9y2Klp_u9cL8hlXoKoUpMkpAd5wabu61A4W0y15E5P&sig=AHIEtbRJ5FAI-3YK-qtayPjKkF_CwOgZag

• full duplex communication over the web w/o flash sockets

  - by aharon

  A web application I'm helping to develop is faced with a well-known problem: we want to be able to let users know of various events and so forth that can occur at any time, essentially at random, and update their view accordingly. Essentially, we need to allow the server to push requests to individual clients, as opposed to the client asking the server. I understand that WebSockets are an effort to address the problem; however, after a bit of looking around into them, I understand that a) very few web browsers currently offer native websocket support; b) to get around this, you either use flash sockets or some sort of AJAX long-polling; c) a special websockets server must be used. Now, we want to offer our service without Flash. And any sort of servers must have some sort of load-balancing capabilities, or at least some software that can do load balancing for them. As of 2008, everyone was saying that Comet-based solutions (e.g., Bayeux) were the way to go for these sort of situations. However, the various protocols seem to have not had much work put into them since then—which leads (finally) to the question. Is Bayeux-flavored Comet still the right tool for jobs like this? If not, what is?

• Relational database data explorer / visualization?

  - by Ian Boyd

  Is there a tool that can let one browse relational data as a graph of connected nodes? For example, i'm faced with trying to cleanse some anomolous data. i can start with two offending rows. In this particular example, the TransactionID should, by business rules, be unique to the table, but i find a transaction that violates that rule: SELECT * FROM LCTTrans WHERE TransactionID = 1075048 LCTID TransactionID ========= ============= 4358 1075048 4359 1075048 2 row(s) affected But really what i want to begin to hunt down all the related data, to try to see which is right. So this hypothetical software would start by showing me these two rows: Next, i want to see that transaction that is linked into this table: Now that transaction points to an MAL, so show me that: Now lets add those two LCTs, that the transaction is "on". A transaction can be on only one LCT, yet this one is pointing to two: Okay computer, both of those LCTs point to an MAL and the transaction that created them, show me those: Those last two transactions, they also point at an MAL, and they themselves point to an LCT, show me those: Okay, now are there any entries in LCTTrans that point to LCTs 4358 or 4359?... And so on, and so on. Now i did all this manually, running single selects, copying and pasting uniqueidentifier keys and converting them into friendly id numbers so i could easily see the relationships. Is there software that can do this?

• How to create minidump of a .NET process when a certain first chance exception occurs.

  - by mark

  Dear ladies and sirs. My application throws InvalidCastException in the QA environment, something I cannot reproduce in development. I wish to obtain the minidump at the exception moment. I know about adplus, but I am not sure how to use it so that it creates the minidump when InvalidCastException is thrown. Apparently, it does not distinguish one .NET exception from another. May be I am wrong and there is a way. Or, there is another tool to do it. Preferably free one. Anyway, can anyone advice how to handle this issue? Thanks. UPDATE The build is a Debug build in both QA and dev. However, QA runs complex scenarios made possible in the lab, which devs cannot reproduce. Hence I need an ability to make dump when running in QA. I can modify the code and create minidump from code. However, I wish for a more flexible solution, the one not requiring to modify the code every time an issue like this occurs.

• Subsonic 3 ActiveRecord nested select for NotIn bug?

  - by Junto

  I have the following Subsonic 3.0 query, which contains a nested NotIn query: public List<Order> GetRandomOrdersForNoReason(int shopId, int typeId) { // build query var q = new SubSonic.Query.Select().Top("1") .From("Order") .Where("ShopId") .IsEqualTo(shopId) .And(OrderTable.CustomerId).NotIn( new Subsonic.Query.Select("CustomerId") .From("Customer") .Where("TypeId") .IsNotEqualTo(typeId)) .OrderDesc("NewId()"); // Output query Debug.WriteLine(q.ToString()); // returned typed list return q.ExecuteTypedList<Order>(); } The internal query appears to be incorrect: SELECT TOP 1 * FROM [Order] WHERE ShopId = @0 AND CustomerId NOT IN (SELECT CustomerId FROM [Customer] WHERE TypeId = @0) ORDER BY NewId() ASC You'll notice that both parameters are @0. I'm assuming that the parameters are enumerated (starting at zero), for each "new" Select query. However, in this case where the two Select queries are nested, I would have expected the output to have two parameters named @0 and @1. My query is based on one that Rob Conery gave on his blog as a preview of the "Pakala" query tool that became Subsonic 3. His example was: int records = new Select(Northwind.Product.Schema) .Where("productid") .In( new Select("productid").From(Northwind.Product.Schema) .Where("categoryid").IsEqualTo(5) ) .GetRecordCount(); Has anyone else seen this behavior? Is it a bug, or is this an error or my part? Since I'm new to Subsonic I'm guessing that this probably programmer error on my part but I'd like confirmation if possible.

• autoconf libtool library linker path incorrect (need drive-letter) for MinGW ld.exe in Cygwin

  - by Tam Toucan

  I use autoconf and when the target is mingw I was using the -mno-cygwin flag. This has been removed so I'm trying to using the mingw tool chain. The problem is the linker isn't finding my libraries /bin/sh ../../../libtool --tag=CXX --mode=link mingw32-g++ -g -Wall -pedantic -DNOMINMAX -D_REENTRANT -DWIN32 -I /usr/local/include/w32api -L/usr/local/lib/w32api -o testRandom.exe testRandom.o -L../../../lib/Random -lRandom libtool: link: mingw32-g++ -g -Wall -pedantic -DNOMINMAX -D_REENTRANT -DWIN32 -I /usr/local/include/w32api -o .libs/testRandom.exe testRandom.o -L/usr/local/lib/w32api -L/home/Tam/src/3DS_Games/lib/Random -lRandom D:\cygwin\opt\MinGW\bin\..\lib\gcc\mingw32\3.4.5\..\..\..\..\mingw32\bin\ld.exe: cannot find -lRandom To link this from the command line using the mingw linker the -L path needs the drive letter i.e mingw32-ld testRandom.o -LD:/home/Tam/src/3DS_Games/lib/Random -lRandom works. The -L path is generated from the makefile.am's which have LDADD = -L$(top_builddir)/lib/Random -lRandom However I can't find how to set top_builddir to a relative path or to start it with the drive letter (my autoconf skills are weak). As a tempoary "solution" I have removed the use of libtool. I could hack a $(DRIVE_LETTER) infront of every -L option, but I'd like to find something better.

• Empty UIView with minimal drawRect: overhead

  - by Benjohn Barnes

  Hi, I have an application that has three nested views that are mechanically important, but have no visual elements: A vanila UIView that doesn't have any content of its own, and is simply used as a host for CALayers. A UIScrollView (that is queried for it's origin and used to position CALayers in 3d: I really only use this view to faithfully replicate the scroll view's "mechanics"), The scroll view's contents: a UIView subclass. It simply picks up touch events and passes them to a delegate - all that is important are its UIResponder machinery. The UIView hosting CALayers is a sibling of a UIImageView that is a background image over which the CALayers are drawn. I'd really like to ensure that none of these empty UIViews have any drawing or compositing overhead (in time, or storage) associated with them, or if that's not possible, to get this overhead as small as possible, and to understand it so that I can perhaps decide if I should try a different approach. In interface builder, I've set all of the views to not clear their context before drawing. I've not set them to be opaque though, because they definitely are not opaque - they are completely transparent. I've found that I need to give the scroll view contents a transparent clear colour (again in IB by setting the background colour's opacity to zero), and this suggests that it is being drawn, which I don't want. So, in short, I've not got much idea of what is and isn't getting drawn (anyone know of a tool like Quartz Debug for iPhone / simulator?), or how to go about stopping things from getting drawn. Advice would be very welcome! Thanks, Benjohn

• Why isn't my UITableView in a popover appearing in the correct scroll position?

  - by zbrimhall

  I have a split view-based app that presents a master-detail interface, and uses a popover to present the master list when in portrait mode. The popover presents a sectioned table view that ultimately gets populated by a subclass of NSFetchedResultsController. I can tap the tool bar button to present the master list, scroll to whatever row, and tap the row to dismiss the popover. My problem is that if the table is scrolled past the top of the second section, when I dismiss the popover and then later tap the toolbar button to re-present it, the table's scroll position is always set such that the first row of the second section is at the top of the list. If I haven't scrolled past the top of the second section, it correctly remembers its scroll position when the table is presented again. Similarly, in landscape mode, if I scroll the table past the top of the third section and then rotate to portrait, when I come back to landscape the scroll position is always set such that the first row of the third section is at the top of the list. I tried calling -scrollToNearestSelectedRowAtScrollPosition:animated in both the master view controller's -viewWillAppear, as well as in the split view delegate's splitViewController:popoverController:willPresentViewController:, to no effect. Anybody have a clue what I might be doing wrong?

• Sorting, Filtering and Paging in ASP.NET MVC

  - by ali62b

  What is the best approach to implement these features and which part of project would involved? I see some example of JavaScript grids, but I'm talking about a general approach which best fits the MVC architecture. I've considered configuring routes and models to implement these features but I don't have a clear idea that if this is the right approach to implementing such features. On the one hand, I think if we put logic in routes (item/page/sort/), we would have benefits like bookmarking and avoiding JavaScript. On the other hand if we use JavaScript grids, we can have behavior like the old school grid views in ASP.NET web forms. I find that using HTML helpers may be useful for paging, but have no idea if they are good for sorting or not. I've looked at jQuery, tableSorter and quick search plug-ins, but they work just on the currently-fetched data and won't help in real sorting and filtering that may need to touch the database. I have some thoughts on using these tools side by side with AJAX to get something which works, but I have no idea if there are similar efforts done yet anywhere. Another approach I looked at was using Dynamic Data on web forms, but I didn't find any suggestions out there as to whether or not it is a good idea to integrate MVC and DD. I know implementing filtering and sorting for an individual case is simple (although it has some issues like using Dynamic LINQ, which is not yet a standard approach), but creating a sorting or filtering tool which works in all cases is the idea I'm looking for. (Maybe this is because I want have something in hand when web form developers are wondering why I'm writing same code each time I want to implement a sort scenario for different Entities).

• Project Architecture For Enhancing Legacy project.

  - by vijay.shad

  I am working on legacy project. Now the situation demands project to be divided into parts. What strategy I should follow to do this task. Description: The legacy project (A) is fully functional web application with almost well defined layers. But now i need to extend the project to a further enhancement. This project usage maven as build tool. But it is used only for dependency managements only. (project exported to war form inside eclipse). The new enhancement needs me to add new data table, new UI(jsp, css, js and images). What should be my strategy to enhance to application. My proposed design. I am planing to create two new projects Project B : Main Enhancement works will done in this project. Will have all layers like service layer, dao layer and UI layer in itself. And will be a web application in itself. Project C : Extract some common model and service code form project-A and create this project. This project will be added as dependency to both the projects. If my this approach is okay! Then i presume there will be problem be problem in deployment. These two projects will demand to deploy separately(currently tomcat is used). But I must deploy these two projects as one war. So, i need to have a plan to change the web.xml entries to have configurations for both projects. This will comes with some more complexities with project. What should be my design for the project? Does my plan sounds good.

• Eclipse plugin development for Eclipse

  - by Raven

  Hi, how do I start to develop a plugin for Eclipse? I need a tool which isn't out there yet for my further development... so my main concerns are: -How to add a perspective? -How to add menu items? -How to add a view into the "Show Views" menu? -How to add to the preference pane? -How do I get information, like * where is the workspace? * which files are open in the editor? * which projects are collapsed / expanded in the left projects view? * ..... -Which conventions (naming...) should I consider? -How to set up update site/deployment? Can you give me some hints, links, tutorials.... Dont get me wrong. I am using Eclipse RCP for developing stand alone apps for quite some time, so I am familiar with the techniques, but I never started to develop a plugin for Eclipse itself. Thanks

• Connection details & timeouts in a java web service client

  - by f1sh

  Hello fellow Coders, I have to implement a webservice client to a given WSDL file. I used the SDK's 'wsimport' tool to create Java classes from the WSDL as well as a class that wrap's the webservice's only method (enhanceAddress(auth, param, address)) into a simple java method. So far, so good. The webservice is functional and returning results correcty. The code looks like this: try { EnhancedAddressList uniservResponse = getWebservicePort().enhanceAddress(m_auth, m_param, uniservAddress); //Where the Port^ is the HTTP Soap 1.2 Endpoint }catch (Throwable e) { throw new AddressValidationException("Error during uniserv webservice request.", e); } The Problem now: I need to get Information about the connection and any error that might occur in order to populate various JMX values (such as COUNT_READ_TIMEOUT, COUNT_CONNECT_TIMEOUT, ...) Unfortunately, the method does not officially throw any Exceptions, so in order to get details about a ConnectException, i need to use getCause() on the ClientTransportException that will be thrown. Even worse: I tried to test the read timeout value, but there is none. I changed the service's location in the wsdl file to post the request to a php script that simply waits forever and does not return. Guess what: The web service client does not time out but waits forever as well (I killed the app after 30+ minutes of waiting). That is not an option for my application as i eventually run out of tcp connections if some of them get 'stuck'. The enhanceAddress(auth, param, address) method is not implemented but annotated with javax.jws.* Annotations, meaning that i cannot see/change/inspect the code that is actually executed. Do i have any option but to throw the whole wsimport/javax.jsw-stuff away and implement my own soap client?

• How do i transfer this unmanaged code from asp to asp.net 2/mvc?

  - by melaos

  hi guys, i'm a newbie to ASP.net interop features, so what i have right here is some unmanaged dll that i need to call from my asp.net mvc app. the dll name is CTSerialNumChecksum.dll set CheckSumObj = Server.CreateObject("CTSerialNumChecksum.CRC32API") validSno = CheckSumObj.ValidateSerialNumber(no) i know it's unmanaged because when i try to add reference to the dll it doesn't work. i try to follow some tutorials on interop and marshalling but thus far i wasn't able to get the code to work. i'm trying to wrap the object into another static class and just let the rest of the app to call the code. using System; using System.Runtime.InteropServices; namespace OnlineRegisteration.Models { public static class SerialNumberChecksum { [DllImport("CTSerialNumChecksum")] public static extern int ValidateSerialNumber(string serialNo); } } Questions: How do i write the class? And what tool can i use to identify what type of dll a particular file is, i.e. unmanaged c++, etc? Also i intend to make use jquery to do ajax call later so i can use this to validate my form pre-submission. Is there a better way to handle this?

• Browser back button restores empty fields

  - by Pierre

  I have a web page x.php (in a password protected area of my web site) which has a form and a button which uses the POST method to send the form data and opens x.php#abc. This works pretty well. However, if the users decides to navigate back in Internet Explorer 7, all the fields in the original x.php get cleared and everything must be typed in again. I cannot save the posted information in a session and I am trying to understand how I can get IE7 to behave the way I want. I've searched the web and found answers which suggest that the HTTP header should contain explicit caching information. Currently, I've tried this : session_name("FOO"); session_start(); header("Pragma: public"); header("Expires: Fri, 7 Nov 2008 23:00:00 GMT"); header("Cache-Control: public, max-age=3600, must-revalidate"); header("Last-Modified: Thu, 30 Oct 2008 17:00:00 GMT"); and variations thereof. Without success. Looking at the returned headers with a tool such as WireShark shows me that Apache is indeed honouring my headers. So my question is: what am I doing wrong?

• Specific programming text editor for simple open/close editing

  - by queen3

  I'm looking for very specific text editor: Closes on ESC, no project management or tabs Syntax highlighting - preferably with color themes (e.g. can apply different color themes without changing C# coloring definition) or, at least, can load/save themes; support for C/C#/XML/HTML/JavaScript/etc - common MS/.NET world - out of box Configurable keys, or: Shift-Tab shifts blocks XML/HTML auto-completion support - well, optional I use synplus plugin for Total Commander currently, but it has few drawbacks (e.g. crashes sometimes ;-), no auto-completion, etc). Basically I want fast Visual-Studio-like editor that I open, do edits, and then close using ESC. I remember I tried Notepad++, etc - most of them open files in tabs, don't close on ESC... - that is, behave like IDE. At least I've just downloaded Notepad++, it doesn't close on ESC even if I setup keybindings to do so. Autocompletion is optional (though it is to be simple as just tags completion), what I really look for is closing on ESC, not getting in the way with all the tabs and IDE-like, and good coloring. Plus shift-tab is must have for blocks manipulation. Update: any open-source one that I can easily tweak to close on ESC? ;-) Seems like ESC (and reasonable color highlighting) is the core requirement. I've just tried many editors - Programmer's Notepad, E, Crimson, etc - I can't set any of them to close on ESC. Any external tool to close selected program on ESC? ;-) UPDATE: Hm, found an awesome utility for my latest thought: http://www.autohotkey.com. Easy to setup to close any window on ESC (as well as many other tricks). Seems like the most tough requirements is gone - I can use ANY text editor ;-)

• How to accurately parse smtp message status code (DSN)?

  - by Geo

  RFC1893 claims that status codes will come in the format below you can read more here. But our bounce management system is having a hard time parsing error status code from bounce messages. We are able to get the raw message, but depending on the email server the code will come in different places. Is there any rule on how to parse this type of messages to obtain better results. We are not looking for the 100% solution but at least 80%. This document defines a new set of status codes to report mail system conditions. These status codes are intended to be used for media and language independent status reporting. They are not intended for system specific diagnostics. The syntax of the new status codes is defined as: status-code = class "." subject "." detail class = "2"/"4"/"5" subject = 1*3digit detail = 1*3digit White-space characters and comments are NOT allowed within a status- code. Each numeric sub-code within the status-code MUST be expressed without leading zero digits. The quote above from the RFC tells one thing but then the text below from a leading tool on bounce management says something different, where I can get a good source of standard status codes: Return Code Description 0 UNDETERMINED - (ie. Recipient Reply) 10 HARD BOUNCE - (ie. User Unknown) 20 SOFT BOUNCE - General 21 SOFT BOUNCE - Dns Failure 22 SOFT BOUNCE - Mailbox Full 23 SOFT BOUNCE - Message Too Large 30 BOUNCE - NO EMAIL ADDRESS. VERY RARE! 40 GENERAL BOUNCE 50 MAIL BLOCK - General 51 MAIL BLOCK - Known Spammer 52 MAIL BLOCK - Spam Detected 53 MAIL BLOCK - Attachment Detected 54 MAIL BLOCK - Relay Denied 60 AUTO REPLY - (ie.

  I'm a big fan of Douglas Crockford's writing on JavaScript, particularly his book JavaScript: The Good Parts. It's made me a better JavaScript programmer and a better programmer in general. One of his tips for his jslint tool is this : ++ and -- The ++ (increment) and -- (decrement) operators have been known to contribute to bad code by encouraging excessive trickiness. They are second only to faulty architecture in enabling to viruses and other security menaces. There is a plusplus option that prohibits the use of these operators. This has always struck my gut as "yes, that makes sense," but has annoyed me when I've needed a looping condition and can't figure out a better way to control the loop than a while( a < 10 )do { a++ } or for (var i=0;i<10;i++) { } and use jslint. It's challenged me to write it differently. I also know in the distant past using things, in say PHP like $foo[$bar++] has gotten me in trouble with off-by-one errors. Are there C-like languages or other languages with similarities that that lack the "++" and "--" syntax or handle it differently? Are there other rationales for avoiding "++" and "--" that I might be missing? UPDATE -- April 9, 2010: In the video Crockford on JavaScript -- Part 5: The End of All Things, Douglas Crockford addresses the ++ issue more directly and with more detail. It appears at 1:09:00 in the timeline. Worth a watch.

• Best way to fork SVN project with Git

  - by Jeremy Thomerson

  I have forked an SVN project using Git because I needed to add features that they didn't want. But at the same time, I wanted to be able to continue pulling in features or fixes that they added to the upstream version down into my fork (where they don't conflict). So, I have my Git project with the following branches: master - the branch I actually build and deploy from feature_* - feature branches where I work or have worked on new things, which I then merge to master when complete vendor-svn - my local-only git-svn branch that allows me to "git svn rebase" from their svn repo vendor - my local branch that i merge vendor-svn into. then i push this (vendor) branch to the public git repo (github) So, my flow is something like this: git checkout vendor-svn git svn rebase git checkout vendor git merge vendor-svn git push origin vendor Now, the question comes here: I need to review each commit that they made (preferably individually since at this point I'm about twenty commits behind them) before merging them into master. I know that I could run git checkout master; git merge vendor, but this would pull in all changes and commit them, without me being able to see if they conflict with what I need. So, what's the best way to do this? Git seems like a great tool for handling forks of projects since you can pull and push from multiple repos - I'm just not experienced with it enough to know the best way of doing this. Here's the original SVN project I'm talking about: https://appkonference.svn.sourceforge.net/svnroot/appkonference My fork is at github.com/jthomerson/AsteriskAudioKonf (sorry - I couldn't make it a link since I'm a new user here)

• How to test an application for correct encoding (e.g. UTF-8)

  - by Olaf

  Encoding issues are among the one topic that have bitten me most often during development. Every platform insists on its own encoding, most likely some non-UTF-8 defaults are in the game. (I'm usually working on Linux, defaulting to UTF-8, my colleagues mostly work on german Windows, defaulting to ISO-8859-1 or some similar windows codepage) I believe, that UTF-8 is a suitable standard for developing an i18nable application. However, in my experience encoding bugs are usually discovered late (even though I'm located in Germany and we have some special characters that along with ISO-8859-1 provide some detectable differences). I believe that those developers with a completely non-ASCII character set (or those that know a language that uses such a character set) are getting a head start in providing test data. But there must be a way to ease this for the rest of us as well. What [technique|tool|incentive] are people here using? How do you get your co-developers to care for these issues? How do you test for compliance? Are those tests conducted manually or automatically? Adding one possible answer upfront: I've recently discovered fliptitle.com (they are providing an easy way to get weird characters written "u?op ?pisdn" *) and I'm planning on using them to provide easily verifiable UTF-8 character strings (as most of the characters used there are at some weird binary encoding position) but there surely must be more systematic tests, patterns or techniques for ensuring UTF-8 compatibility/usage. Note: Even though there's an accepted answer, I'd like to know of more techniques and patterns if there are some. Please add more answers if you have more ideas. And it has not been easy choosing only one answer for acceptance. I've chosen the regexp answer for the least expected angle to tackle the problem although there would be reasons to choose other answers as well. Too bad only one answer can be accepted. Thank you for your input. *) that's "upside down" written "upside down" for those that cannot see those characters due to font problems
