• Why avoid pessimistic locking in a version control system?

  - by raven

  Based on a few posts I've read concerning version control, it seems people think pessimistic locking in a version control system is a bad thing. Why? I understand that it prevents one developer from submitting a change while another has the file checked out, but so what? If your code files are so big that you constantly have more than one person working on them at the same time, I submit that you should reorganize your code. Break it up into smaller functional units. Integration of concurrent code changes is a tedious and error-prone process even with the tools a good version control system provides to make it easier. I think it should be avoided if at all possible. So, why is pessimistic locking discouraged?

• How to integrate access control with my ORM in a .net windows form application?

  - by Ying

  I am developing a general database query tools, a .Net 3.5 Windows Form application. In order to make the presentation layer is independent of the database layer. I use an ORM framework, XPO from DevExpress. But, I have no access control function built in. I surfed Internet and I found in WCF Data Services, there is an interesting concept, Interceptor, which is following AOP(Aspect Oriented Programming). I am wondering who has such an experience to build access control in ORM. My basic requirement is : It should be a general method and controlled by users in runtime. So any hard coding is not acceptable. It could be based on attribute, database table, or even an external assembly. I am willing to buy a ready solution. According to the idea of AOP, an access control function can be integrated with existing functions easily and nearly not knowingly to the previous developer;) Any suggestions are welcome.

• Why do Java source files go into a directory structure?

  - by bdhar

  Suppose that I am creating a Java project with the following classes com.bharani.ClassOne com.bharani.ClassTwo com.bharani.helper.HelperOne com.bharani.helper.support.HelperTwo with files put immediately under the folder 'src' src/ClassOne.java src/ClassTwo.java src/HelperOne.java src/HelperTwo.java and compile them using the command $ javac src/*.java -d classes (assuming that classes directory exists) The compiler compiles these files and put the class files in appropriate sub-directories inside the 'classes' directory like this classes/com/bharani/ClassOne.class classes/com/bharani/ClassTwo.class classes/com/bharani/helper/HelperOne.class classes/com/bharani/helper/support/HelperTwo.class Because the spec mandates that the classes should go inside appropriate directory structure. Fine. My question is this: When I use an IDE such as Eclipse or NetBeans, they create the directory structure for the source code directory ('src' directory here) also. Why is that? Is it mandatory? Or, is it just a convention? Thanks.

• Where can I find a deliberately insecure open source web application?

  - by Phil Laliberte

  As a developer, I've learned that I usually gain a better understanding of best/worst practices through experience. The area of web application security isn't really somewhere where my organization can afford to let developers learn through trial and error. So looking for a hands-on approach to knowledge sharing of best practices in web application security, I was thinking that it would be useful to have an open source application that was deliberately built to be insecure in order to help teach junior developers about application security. Does anyone out there know where to find something like this?

• Print new line in the source-code with jQuery.

  - by Kucebe

  I have a simple function in jQuery that creates new elements in the DOM. the problem is in the html source code, it append every element in the same line, and it's very bad to read. function _loadNewElements(elements){ for(var i=0; i<elements.length; i++){ var fixedElement = $('<img />') var position = elements[i].position; var cssMap = { 'position': 'fixed', 'top': position.top + "px", 'left': position.left + "px" }; fixedElement.css(cssMap); fixedElement.addClass("fixedTag"); fixedElement.attr('alt', elements[i].text); fixedElement.attr('src', "elements/" + elements[i].id + ".png"); fixedElement.appendTo($('#board')); //i'd like to print something here like ("\n"); } } I tried document.write("\n") but in this context it doesn't work. Any solution?

• How Much Does Source Code Cost? Range?

  - by Brain Freeze

  I have taken a job selling a customized "online workplace management application." Our clients' businesses work around the application. Our clients track their time (which is how they get paid), finances and work documents through the application we provide and give their clients access to their interests throught the application. Our clients range from 2 users to 500 users. Each user probably processes 200 files per year and generates a fee for each file in the range of $500-$2500 per file. The application has been refined over a period of years and has cost around a million to develop. Does anyone know what range something like this sells for (source code, add-ons such as support and hosting)? I am trying to wrap my head around it as my background is not in software development.

• How to automatically check out a database file in a source controlled web application ?

  - by TheRHCP

  Hello, I am working on an ASP.NET web application, we are a small team (4 students) and we do not have access to a dedicated server to host the database instance. So for this web application we decided just to put the database file in the App_Data folder. The problem is that our project is source controled on TFS, so every time you open the solution and try to launch the web application, we get an expcetion saying that database is read-only. That is logical because the databse file is not automatically checked-out. Is there a workaround to avoid a manual check-out of the database file everytime we open the solution ? Thanks.

• Is there a generic open-source reporting system out there?

  - by syntactico

  I recently started a position at a new company, and one of the first projects they want is an internal reporting system that points at database A, B, C and reports various metrics/statistics/predictions. Basically, the same thing I've done or worked on and every company I've ever been hired by. Since this gets a bit boring after a while, I was wondering if there already exists some sort of open-source package that accomplishes this goal. Ideally, it would work with multiple databases out-of-box (PostgreSQL, MySQL, MSSQL, Oracle minimally), determine relationships between tables (either automatically from their schemas, or allow you to manually set them up after pooling all the tables), allow you to create reports based on a subset of tables, customizing what data you wanted to be displayed/calculated (I suppose this would be challenging since you've no idea what every audience wants, and would need to make this flexible) I'm debating making something like this in my spare time if one does not already exist. Just curious.

• Cannot step into .NET framework source with VS2008 SP1.

  - by Vilx-

  Somehow my VS2008 SP1 has lost the ability to step into .NET framework sources. I've played around with checkboxes to no end; I've re-deleted the Symbol cache folder a dozen times; and I've tried all kinds of debug symbol servers. All it does is download some .PDB files, but when I try to select a stack frame in .NET, I always get the message about no source available and "do you want to view disassembly". What gives? Added: Web application; Windows Vista Business x32; .NET 3.5 SP1.

• Will a source-removal sort always return a maximal cycle?

  - by Jason Baker

  I wrote a source-removal algorithm to sort some dependencies between tables in our database, and it turns out we have a cycle. For simplicity, let's say we have tables A, B, C, and D. The edges are like this: (A, B) (B, A) (B, C) (C, D) (D, A) As you can see, there are two cycles here. One is between A and B and another is between all four of them. Will this type of sort always choke on the largest cycle? Or is that not necessarily the case?

• What open source C/C++ audio compression options are there besides LAME MP3?

  - by Ole Jak

  Are there any C/C++ open source audio encoder besides LAME MP3? It doesn't need to be exactly mp3 format, I need a "compressed digital audio file". I do not want to use Lame because it is too big while no programmer can answer a simple question on it (share simple but easily downloadable and readable project containing only needed 2 simple functions... So I'm tired of searching for help with it.. I need something fresh powerful but more readable than this lib I found (mp3stego) ) "I don't want LAME because I am a fighter with its monopoly" Haha..

• How to get the set events of a control?

  - by Jack

  It's possible via C# code get an list of methods/delegates that was set to Control? let me explain better.. For example. Assuming some definitions like this: foo.Click += (a, b) => { ... } //.. foo.Click += (A,B) => { ... } And a megic method: var baa = foo.GetEvents("Click"); Returns baa[0] points to (a, b) => { ... } baa[1] points to (A,B) => { ... } My scenery: I make and add dynamically event to some controls inside a loop. I want depending to a boolean value a event of control of index one,will removed by using control.Click -= baa[1] or something like this. I hope this is clear for your. Thanks in advance.

• My company is a Rackspace Cloud client (provided to us for free) and I'm trying to find some way to set up version control

  - by Nick S.

  As the title says, my (small) business is provided a free Rackspace Cloud client account. We receive a decent amount of traffic but I haven't been able to put together a business case to move to our own server yet. However, we are developing some complex apps and I'm frustrated with not having the ability to even ssh into the remote server. Ultimately, I'd like to set up some sort of version control (at this point, I'll take anything, git or otherwise). I have control over databases, can FTP, set up cron jobs, and perform a few other basic functions. I can't think of any way to set up git or something similar without ssh access. A thought went through my mind that maybe some sort of PHP version control exists that I might be able to set up, but I haven't had any luck finding it yet. Do you guys have any ideas, thoughts, or advice?

• Error trapping for a missing data source in a Spring MVC / Spring JDBC web app [migrated]

  - by Geeb

  I have written a web app that uses Spring MVC libraries and Spring JDBC to connect to an Oracle DB. (I don't use any ORM type libraries as I create stored procedures on Oracle that do my stuff and I'm quite happy with that.) I use a connection pool to Oracle managed by the Tomcat container The app generally works absolutely fine by the way! BUT... I noticed the other day when I tried to set up the app on another Tomcat instance that I had forgotten to configure the connection pool and obviously the app could not get hold of an org.apache.commons.dbcp.BasicDataSource object, so it crashed. I define the pool params in the tomcat "context.conf" In my "web.xml" I have: <servlet> <servlet-name>appServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/Spring/appServlet/servlet-context.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>appServlet</servlet-name> <!-- Map *everything* to appServlet --> <url-pattern>/</url-pattern> </servlet-mapping> <resource-ref> <description>Oracle Datasource example</description> <res-ref-name>jdbc/ora1</res-ref-name> <res-type>org.apache.commons.dbcp.BasicDataSource</res-type> <res-auth>Container</res-auth> </resource-ref> And I have a Spring "servlet-context.xml" where JNDI is used to map the data source object provided by the connection pool to a Spring bean with the ID of "dataSource": <jee:jndi-lookup id="dataSource" jndi-name="java:comp/env/jdbc/ora1" resource-ref="true" /> Here's the question: Where do I trap the case where the database cannot be accessed for whatever reason? I don't want the user to see a yard-and-a-half of Java stack trace in their browser, rather a nicer message that tells them there is a database problem etc. It seems that my app tries to configure the "dataSource" bean (in "servlet-context.xml") before any code has tested it can actually provide a dataSource object from the pool?! Maybe I'm not fully understanding exactly what is going on in these stages of the app firing up ... Thanks for any advice!

• Errors when attempting to update source files, Server 2012R2 (errors 80073701 and 14081)

  - by jeremy

  I have a Windows Server 2012R2 machine that I installed with Server Core, and then decided that I wanted to switch to GUI. I'll make the long story short: I ran windows updates, and now the source files are older/out of sync with the operating system, and I need to update the source files. Here are a couple of articles that outline how this is supposed to work: http://blog.coretech.dk/kaj/why-i-cant-convert-my-windows-server-2012-r2-core-to-gui/ http://blogs.technet.com/b/joscon/archive/2012/11/14/how-to-update-local-source-media-to-add-roles-and-features.aspx I have followed these instructions, but the updates are not successfully updating the source. I get errors like: "An error occurred - Package_for_KB29671203 Error: 0x80073701, Error: 14081, The referenced assembly could not be found." or "add-windowspackage failed. error code = 0x80073701, add-windowspackage: the referenced assembly could not be found" I've extensively searched for help on those error codes related to Server 2012 and windows updates, but my google-fu is failing me. I am using windows update packages found in c:\Windows\SoftwareDistribution\Download How can I get these updates to bring my source files up to current? Thanks!

• Why can’t GridView extract child control’s values directly?

  - by SourceC

  Hello using Bind in a GridView control template enables the control to extract values from child controls in the template and pass them to the data source control. The data source control in turn performs the appropriate command for the database. For this reason, the Bind function is used inside the EditItemTemplate or InsertItemTemplate of a data-bound control. Why is Bind() needed to extract values and pass them to GridView. Why isn’t GridView able to extract child control’s values directly? thanx

• silent failure while creating odbc data source

  - by Peter

  I just got really confused trying to create an ODBC data source in Windows 2003 R2. I can create a connection to my chosen server (a MS SQL Server) on the "user DSN" tab, but when I try to do the same thing on the "system DSN tab", the process fails but without an error message. I am able to connect to the target database fine at the end of configuring a new data source, but when I click OK, the data source just isn't there. No error message, no sign that anything went amiss, other than the lack of a new data source. Very annoying, as I had to repeat the process a few times to make sure I wasn't crazy. Anybody got any hints? I suspect it is a permission problem of some sort but since there is no error message, I don't know where to start.

• JOAL with JNLPAppletLauncher Problem

In order to avoid annoying dialogues I wanted to load JOAL with the JNLPAppletLauncher as it is shown on https://jogl-demos.dev.java.net/applettest-joal.html Unfortunately with this approach I get this exception: JNLPAppletLauncher.loadLibrary("joal_native") loading: C:\Users\Barbara\AppData\Local\Temp\jnlp-applet\jln7379734545861869319\jln1640167325490042232\joal_native.dll Exception in thread "AWT-EventQueue-2" java.lang.RuntimeException: Can not get proc address for method "alcCaptureCloseDevice": Couldn't set value of field "_addressof_alcCaptureCloseDevice" in class net.java.games.joal.impl.ALCProcAddressTable at com.sun.gluegen.runtime.ProcAddressHelper.resetProcAddressTable(ProcAddressHelper.java:113) at net.java.games.joal.impl.ALProcAddressLookup.resetALCProcAddressTable(ALProcAddressLookup.java:109) at net.java.games.joal.impl.ALCImpl.alcOpenDevice(ALCImpl.java:341) at net.java.games.joal.util.ALut.alutInit(ALut.java:69) at demos.devmaster.lesson1.SingleStaticSource.initialize(SingleStaticSource.java:194) at demos.devmaster.lesson1.SingleStaticSource.access$000(SingleStaticSource.java:57) at demos.devmaster.lesson1.SingleStaticSource$1.actionPerformed(SingleStaticSource.java:79) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) Caused by: java.lang.RuntimeException: Unable to find and load OpenAL library at net.java.games.joal.impl.ALProcAddressLookup$DynamicLookup.dynamicLookupFunction(ALProcAddressLookup.java:66) at com.sun.gluegen.runtime.ProcAddressHelper.resetProcAddressTable(ProcAddressHelper.java:106) ... 30 more I am using Firefox 3.6.3, Java 1.6._017 and am on a Windows 7 Machine. I also tried this on another computer with Windows XP and on one with Linux, always with the same result, so it does not seem to be specific for my computer. I also get the same result for IE8. Any ideas how I could fix this? Thank you very much.

• Event Log "Wake Source" when system wakes from sleep

  - by Doltknuckle

  So I've been troubleshooting sleep timers for our systems and have run across an interesting issue. I need a way to report how long a system was awake after a number of different inputs. Now, I've discovered that the System Log tracks wake and sleep events and even tells you the times that everything happens at. The thing is doesn't tell you is what triggered the wake event. It does give you a numerical code however. Here are some examples of what I am finding. Index : 2901 EntryType : Information InstanceId : 1 Message : The system has resumed from sleep. Sleep Time: 2010-10-01T23:20:06.097488100Z Wake Time: 2010-10-03T17:41:12.796400500Z Wake Source: 0 Category : (0) CategoryNumber : 0 Source : Microsoft-Windows-Power-Troubleshooter -- Index : 2841 EntryType : Information InstanceId : 1 Message : The system has resumed from sleep. Sleep Time: 2010-10-01T19:19:37.239789600Z Wake Time: 2010-10-01T21:28:48.921200800Z Wake Source: 4HID Keyboard Device Category : (0) CategoryNumber : 0 Source : Microsoft-Windows-Power-Troubleshooter So here's my question: Does anyone know what the different numerical codes for the "Wake Source" mean? I think "0" is a magic packet and "4" is a USB device. Does anyone have any idea if there is any documentation out there on this for Windows 7? Thanks in advance

• Source control on internet i.e. no private networks.

  - by Kavitesh Singh

  Me and my friend are in the process of starting a small project and want to implement a source control. Now both are located in different cities and can communicate using internet for file sharing etc. I need an online hosting solution or any way where i can maintain the source code repository for both of us to check in/out. As of now we want to maintain it as private project. Does sourceforge allow hosting projects which would not be opensource? One option i was thinking, to obtain a static IP form ISP and host the repository.But that mean my system needs to be online when my friend wants to checkin/out or do some diff with old version code. Secondly, would SVN or git be a better choice in such a situation. I have no experience in git/mercurial as of now.
