• How to Setup Java Application

  - by Ari

  I have a 'desktop' java application which is in the form of a jar file. How can I: Store this application on a single server. Grant access via Terminal Services to a specific OU to run this application from the central location. Disallow the copying or moving of the application (jar file) to any other location. Allow the saving/copying/moving of the output of the application on an authorized user's local drive. Thanks.

• Reporting System architecture for better performance

  - by pauloya

  Hi, We have a product that runs Sql Server Express 2005 and uses mainly ASP.NET. The database has around 200 tables, with a few (4 or 5) that can grow from 300 to 5000 rows per day and keep a history of 5 years, so they can grow to have 10 million rows. We have built a reporting platform, that allows customers to build reports based on templates, fields and filters. We face performance problems almost since the beginning, we try to keep reports display under 10 seconds but some of them go up to 25 seconds (specially on those customers with long history). We keep checking indexes and trying to improve the queries but we get the feeling that there's only so much we can do. Off course the fact that the queries are generated dynamically doesn't help with the optimization. We also added a few tables that keep redundant data, but then we have the added problem of maintaining this data up to date, and also Sql Express has a limit on the size of databases. We are now facing a point where we have to decide if we want to give up real time reports, or maybe cut the history to be able to have better performance. I would like to ask what is the recommended approach for this kind of systems. Also, should we start looking for third party tools/platforms? I know OLAP can be an option but can we make it work on Sql Server Express, or at least with a license that is cheap enough to distribute to thousands of deployments? Thanks

• new project app; use entirely node.js

  - by Jared

  I have been looking into Node.js, express and Nowjs and love how easy it is to have real time interactions between clients. My background is mostly from CodeIgniter MVC using PHP and MYSql. I want to re make a current web project of mine from scratch to make everything better and more real time with this newer technology. After researching and doing test examples I want to use node.js , express and Nowjs for the real time interactions once someone connects to the socket.io to pull data back to clients. But use Code Igniter for the control of the site and user management , possible shopping cart/store , pretty much everything else. This is purely due to time constraints and that I am already familiar with doing it that way. I have been looking at MongoDB as an alternative to MySql, Basically the app is going to be multiple chat rooms all on one page. with the ability of notifications and private messaging. Lots of data transfer and images. before I started piecing it together I wanted to get people who have already done something similar. My model would use Code Igniter and MySQL to render the page and then connect them onto a node.js server and broadcast using express and nowjs would using a mongoDB be better than mySQL for tons of messages and data being stored or MYSQL? Also does it make since to not make the whole site on Node.js , kinda piece it together like that?

• How Visual WebGui helps ASP.NET Cloud-based apps

  - by Visual WebGui

  Everyone is talking about Cloud computing and moving to the cloud (public or private), but very few have actually done it so far. The reason is that the process of migrating existing applications to the cloud is a lot more complicated than one might think which is exactly where the Visual WebGui technology comes in for a rescue. In the past year the Visual WebGui R&D Team have been intensively working on a tool-based solution that gives Microsoft application developers and enterprises a simpler...(read more)

• Cross platform application revolution

  - by anirudha

  Every developer know that if they make a windows application that they work only on windows. that’s a small pity thing we all know. this is a lose point for windows application who make developer thing small means only for windows and other only for mac. this is a big point behind success of web because who purchase a operating system if they want to use a application on other platform. why they purchase when they can’t try them. that’s a thing better in Web means IE 6 no problem IE 6 to IE 8 chrome to chrome 8 Firefox to Firefox 3.6.13 even that’s beta no problem the good website is shown as same as other browser. some minor difference may be can see. the cross platform application development thinking is much big then making a application who is only for some audience. the difference between audience make by OS what they use Windows or mac. if they use mac they can’t use this they use windows they can’t use this. Web for Everyone starting from a children to grandfather. male and female Everyone can use internet.no worrying what you have even you have Windows or mac , any browser even as silly IE 6. the cross platform have a good thing that “People”. everyone can use them without a problem that. just like some time problem come in windows that “some component is missing click here to get them” , you can’t use this [apps] software because you have windows sp1 , sp2  sp3. you need to install this first before this. this stupidity mainly comes in Microsoft software. in last year i found a issue on WPI that they force user to install another software when they get them from WPI. ex:- you need to install Visual studio 2008 before installing Visual studio 2010 express. are anyone tell me why user get old version 2008 when they get latest and express version. i never try again their to check the issue is solved or not. a another thing is you can’t get IE 9 on windows XP version. in that’case don’t thing and worrying about them because Firefox and Chrome is much better. the stupidity from Microsoft is too much. they never told you about Firebug even sometime they discuss about damage tool in IE they called them developer tool because they are Microsoft and they only thing how they can market their products. you need to install many thing without any reason such as many SQL server component even you use other RDBMS. you can’t say no to them because you need a tool and tool require a useless component called SQL server. i never found any software force me to install this for this and this for this before install me. that’s another good thing in WEB that no thing require i means you not need to install dotnet framework 4 before enjoy facebook or twitter. may be you found out that Microsoft's fail project Window planet force you to get silverlight before going their. i never hear about them. some month ago my friend talked to me about them i found nothing better their. Wha’t user do when facebook force user to install silverlight or adobe flash or may be Microsoft dotnet framework 4. if you not install them facebook tell  you bye bye tata ! never come here before installing Microsoft dotnet framework 4. the door is open for you after installing them not before. the story is same as “ tell me sorry before coming in home” as mother says to their child when they do something wrong. the web never force you to do something for them. sometime they allow you to use other website account their that’s very fast login for you. because they know the importance of your time.

• Part 15: Fail a build based on the exit code of a console application

  In the series the following parts have been published Part 1: Introduction Part 2: Add arguments and variables Part 3: Use more complex arguments Part 4: Create your own activity Part 5: Increase AssemblyVersion Part 6: Use custom type for an argument Part 7: How is the custom assembly found Part 8: Send information to the build log Part 9: Impersonate activities (run under other credentials) Part 10: Include Version Number in the Build Number Part 11: Speed up opening my build process template Part 12: How to debug my custom activities Part 13: Get control over the Build Output Part 14: Execute a PowerShell script Part 15: Fail a build based on the exit code of a console application When you have a Console Application or a batch file that has errors, the exitcode is set to another value then 0. You would expect that the build would see this and report an error. This is not true however. First we setup the scenario. Add a ConsoleApplication project to your solution you are building. In the Main function set the ExitCode to 1     class Program    {        static void Main(string[] args)        {            Console.WriteLine("This is an error in the script.");            Environment.ExitCode = 1;        }    } Checkin the code. You can choose to include this Console Application in the build or you can decide to add the exe to source control Now modify the Build Process Template CustomTemplate.xaml Add an argument ErrornousScript Scroll down beneath the TryCatch activity called “Try Compile, Test, and Associate Changesets and Work Items” Add an Sequence activity to the template In the Sequence, add a ConvertWorkspaceItem and an InvokeProcess activity (see Part 14: Execute a PowerShell script  for more detailed steps) In the FileName property of the InvokeProcess use the ErrornousScript so the ConsoleApplication will be called. Modify the build definition and make sure that the ErrornousScript is executing the exe that is setting the ExitCode to 1. You have now setup a build definition that will execute the errornous Console Application. When you run it, you will see that the build succeeds. This is not what you want! To solve this, you can make use of the Result property on the InvokeProcess activity. So lets change our Build Process Template. Add the new variables (scoped to the sequence where you run the Console Application) called ExitCode (type = Int32) and ErrorMessage Click on the InvokeProcess activity and change the Result property to ExitCode In the Handle Standard Output of the InvokeProcess add a Sequence activity In the Sequence activity, add an Assign primitive. Set the following properties: To = ErrorMessage Value = If(Not String.IsNullOrEmpty(ErrorMessage), Environment.NewLine + ErrorMessage, "") + stdOutput And add the default BuildMessage to the sequence that outputs the stdOutput Add beneath the InvokeProcess activity and If activity with the condition ExitCode <> 0 In the Then section add a Throw activity and set the Exception property to New Exception(ErrorMessage) The complete workflow looks now like When you now check in the Build Process Template and run the build, you get the following result And that is exactly what we want.   You can download the full solution at BuildProcess.zip. It will include the sources of every part and will continue to evolve.

• Security in Software

  The term security has many meanings based on the context and perspective in which it is used. Security from the perspective of software/system development is the continuous process of maintaining confidentiality, integrity, and availability of a system, sub-system, and system data. This definition at a very high level can be restated as the following: Computer security is a continuous process dealing with confidentiality, integrity, and availability on multiple layers of a system. Key Aspects of Software Security Integrity Confidentiality Availability Integrity within a system is the concept of ensuring only authorized users can only manipulate information through authorized methods and procedures. An example of this can be seen in a simple lead management application.  If the business decided to allow each sales member to only update their own leads in the system and sales managers can update all leads in the system then an integrity violation would occur if a sales member attempted to update someone else’s leads. An integrity violation occurs when a team member attempts to update someone else’s lead because it was not entered by the sales member.  This violates the business rule that leads can only be update by the originating sales member. Confidentiality within a system is the concept of preventing unauthorized access to specific information or tools.  In a perfect world the knowledge of the existence of confidential information/tools would be unknown to all those who do not have access. When this this concept is applied within the context of an application only the authorized information/tools will be available. If we look at the sales lead management system again, leads can only be updated by originating sales members. If we look at this rule then we can say that all sales leads are confidential between the system and the sales person who entered the lead in to the system. The other sales team members would not need to know about the leads let alone need to access it. Availability within a system is the concept of authorized users being able to access the system. A real world example can be seen again from the lead management system. If that system was hosted on a web server then IP restriction can be put in place to limit access to the system based on the requesting IP address. If in this example all of the sales members where accessing the system from the 192.168.1.23 IP address then removing access from all other IPs would be need to ensure that improper access to the system is prevented while approved users can access the system from an authorized location. In essence if the requesting user is not coming from an authorized IP address then the system will appear unavailable to them. This is one way of controlling where a system is accessed. Through the years several design principles have been identified as being beneficial when integrating security aspects into a system. These principles in various combinations allow for a system to achieve the previously defined aspects of security based on generic architectural models. Security Design Principles Least Privilege Fail-Safe Defaults Economy of Mechanism Complete Mediation Open Design Separation Privilege Least Common Mechanism Psychological Acceptability Defense in Depth Least Privilege Design PrincipleThe Least Privilege design principle requires a minimalistic approach to granting user access rights to specific information and tools. Additionally, access rights should be time based as to limit resources access bound to the time needed to complete necessary tasks. The implications of granting access beyond this scope will allow for unnecessary access and the potential for data to be updated out of the approved context. The assigning of access rights will limit system damaging attacks from users whether they are intentional or not. This principle attempts to limit data changes and prevents potential damage from occurring by accident or error by reducing the amount of potential interactions with a resource. Fail-Safe Defaults Design PrincipleThe Fail-Safe Defaults design principle pertains to allowing access to resources based on granted access over access exclusion. This principle is a methodology for allowing resources to be accessed only if explicit access is granted to a user. By default users do not have access to any resources until access has been granted. This approach prevents unauthorized users from gaining access to resource until access is given. Economy of Mechanism Design PrincipleThe Economy of mechanism design principle requires that systems should be designed as simple and small as possible. Design and implementation errors result in unauthorized access to resources that would not be noticed during normal use. Complete Mediation Design PrincipleThe Complete Mediation design principle states that every access to every resource must be validated for authorization. Open Design Design PrincipleThe Open Design Design Principle is a concept that the security of a system and its algorithms should not be dependent on secrecy of its design or implementation Separation Privilege Design PrincipleThe separation privilege design principle requires that all resource approved resource access attempts be granted based on more than a single condition. For example a user should be validated for active status and has access to the specific resource. Least Common Mechanism Design PrincipleThe Least Common Mechanism design principle declares that mechanisms used to access resources should not be shared. Psychological Acceptability Design PrincipleThe Psychological Acceptability design principle refers to security mechanisms not make resources more difficult to access than if the security mechanisms were not present Defense in Depth Design PrincipleThe Defense in Depth design principle is a concept of layering resource access authorization verification in a system reduces the chance of a successful attack. This layered approach to resource authorization requires unauthorized users to circumvent each authorization attempt to gain access to a resource. When designing a system that requires meeting a security quality attribute architects need consider the scope of security needs and the minimum required security qualities. Not every system will need to use all of the basic security design principles but will use one or more in combination based on a company’s and architect’s threshold for system security because the existence of security in an application adds an additional layer to the overall system and can affect performance. That is why the definition of minimum security acceptably is need when a system is design because this quality attributes needs to be factored in with the other system quality attributes so that the system in question adheres to all qualities based on the priorities of the qualities.

• Application Performance: The Best of the Web

  - by Michaela Murray

  Wisdom A deep understanding and realization […] resulting in the ability to apply perceptions, judgements and actions. It is also the comprehension of what is true coupled with optimum judgment as to action. - Wikipedia We’re writing a book for ASP.NET developers, and we want you to be a part of it. We know that there’s a huge amount of web developer wisdom that never gets shared, and we want to find those golden nuggets of knowledge and experience, and make sure everyone can learn from them. Right now, we want to find out about your top tips, hard-won lessons, and sage advice for avoiding, finding, and fixing application performance problems. If you work with .NET and SQL, even better – a lot of application performance relies on the interaction with the database, so we want to hear from you! “How Do You Want Me To Be Involved?” Right! Details! We want you, our most excellent readers, to email us with the Best Advice you would give to other developers for getting the best performance out of their applications. It doesn’t matter if your advice is for newbies or veterans, .NET or SQL – so long as it’s about application performance, we want to hear from you. (And if you think that there’s developer wisdom out there that “everyone knows”, a) I’m willing to bet you could find someone who doesn’t know about it, and b) it probably bears repeating anyway!) “I’m Interested. What Can You Do For Me?” Excellent question. For starters, there’s a chance to win a Microsoft Surface (the tablet, not the table-top). Once all the ASP.NET Wisdom has been collected, tallied, and labelled, it will then be weighed and measured by a team of expert judges (whose identities are still a closely-guarded secret).  The top tip in both SQL & .NET categories will each win their author their very own MS Surface. But that’s not all! We can also give you… immortality! More details? Ok. We’ll be collecting all of the tips sent in by our readers (and we can’t wait to learn from you all,) and with the help of our Simple-Talk editors, we will publish and distribute your combined and documented knowledge as a free, community-created, professionally typeset eBook. You will naturally be credited by name / pseudonym / twitter handle / GitHub username / StackOverflow profile / Whatever, as the clearly ingenious author of hot performance tips. The Not-Very-Fine Print Here’s the breakdown: We want to bring together the best application performance knowledge from ASP.NET developers. Closing date for submissions will be 9am GMT, December 4th. Submissions should be made by email – [email protected] Submissions will be judged by a panel of expert judges (who will be revealed soon). The top submission in both the SQL & .NET categories will each win a Microsoft Surface. ALL the tips which make it through the judging process will be polished by Simple-Talk editors, and turned into a professionally typeset eBook, which will be freely available, and promoted alongside the ANTS Performance Profiler tool. Anyone whose entry makes it into the book will be clearly and profusely credited in the method of their choice (or can remain anonymous.) The really REALLY short version Share what you know about ASP.NET application performance for a chance to win a Microsoft Surface, and then get your name credited in a slick eBook with top-notch production values. For more details, see above. We can’t wait to learn from you!

• Characteristics of a Web service that promote reusability and change

  Characteristics of a Web service that promote reusability and change:  Standardized Data Exchange Formats (XML, JSON) Standardized communication protocols (Soap, Rest) Promotes Loosely Coupled Systems  Standardized Data Exchange Formats (XML, JSON) XML W3.org defines Extensible Markup Language (XML) as a simplistic text format derived from SGML. XML was designed to solve challenges found in large-scale electronic publishing. In addition,  XML is playing an important role in the exchange of data primarily focusing on data exchange on the web. JSON JavaScript Object Notation (JSON) is a human-readable text-based standard designed for data interchange. This format is used for serializing and transmitting data over a network connection in a structured format. The primary use of JSON is to transmit data between a server and web application. JSON is an alternative to XML. Standardized communication protocols (Soap, Rest) Soap W3Scools.com defines SOAP as a simple XML-based protocol. This protocol lets applications exchange data over HTTP.  SOAP provides a way to communicate between applications running on different operating systems, with different technologies and programming languages. Rest In 2007, Stefan Tilkov defines Representational State Transfer (REST) as a set of principles that outlines how Web standards are supposed to be used.  Using REST in an application will ensure that it exploits the Web’s architecture to its benefit. Promotes Loosely Coupled Systems “Loose coupling as an approach to interconnecting the components in a system or network so that those components, also called elements, depend on each other to the least extent practicable. Coupling refers to the degree of direct knowledge that one element has of another.” (TechTarget.com, 2007) “Loosely coupled system can be easily broken down into definable elements. The extent of coupling in a system can be measured by mapping the maximum number of element changes that can occur without adverse effects. Examples of such changes include adding elements, removing elements, renaming elements, reconfiguring elements, modifying internal element characteristics and rearranging the way in which elements are interconnected.” (TechTarget.com, 2007) References: W3C.

• Partner Blog: Hub City Media Introduces iPad Application for Oracle Identity Analytics

  - by Tanu Sood

  About the Writer:Steve Giovannetti is CTO of Hub City Media, Inc., a company that specializes in implementation and product development on the Oracle Identity Management platform. Recently, Hub City Media announced the introduction of iPad application IdentityCert for Oracle Identity Analytics. This post explore the business use cases and application of IdentityCert.Hub City Media(HCM) has been deploying certification solutions based on Oracle Identity Analytics since it first appeared on the market as Vaau RBACx. With each deployment we've seen the same pattern repeat time and time again:1. Customers suffering under the weight of manual access certification regimens deploy Oracle Identity Analytics (OIA) for automated certification. 2. OIA improves the frequency, speed, accuracy, and participation of certifications across the organization. 3. Then the certifiers, typically managers and supervisors, ask, “Is there any easier way to do these certifications offline?”The current version of OIA has a way to export certification data to a spreadsheet.  For some customers, we've leveraged this feature and combined it with some of our own custom code to provide a solution based on spreadsheet exports and imports.  Customers export the certification to Microsoft Excel, complete it, and then import the spreadsheet to OIA. It worked well for offline certification, but if the user accidentally altered the format of the spreadsheet, the import of the data could fail. We were close to a solution but it wasn’t reliable.Over the past few years, we've seen the proliferation of Apple iOS devices, specifically the iPhone and iPad, in the enterprise.  As our customers were asking for offline certification, we noticed the same population of users traditionally responsible for access certification, were early adopters of the iPad. The environment seemed ideal for us to create an iPad application to support offline certifications using Oracle Identity Analytics. That’s why we created IdentityCert™.IdentityCert allows users to view their analytics dashboard, complete user certifications, and resolve policy violations with OIA, from their iPads.The current IdentityCert analytics dashboard displays the same charts that are available in the Oracle Identity Analytics product. However, we plan to expand the number of available analytics in future releases.The main function of IdentityCert is user certification which can be performed quickly and efficiently using a simple touch interface. Managers tap into a certification, use simple gestures to claim users and certify their access.  Certifications can be securely downloaded to IdentityCert and can be completed with or without a network connection. The user can upload the completed certifications once they are connected to a cellular or wi-fi network.Oracle Identity Analytics can generate policy violation notifications based on detective scans of identity warehouse or via preventative analysis of identity access requests. IdentityCert allows users to view all policy violations, resolve, or delegate them to appropriate users. IdentityCert also analyzes the policy violation expression and produces more human friendly descriptions of the policy violation which improves the ability of users to resolve the violation. IdentityCert can be deployed quickly into a customer's environment. It is deployed with Hub City Media's ID Services to connect Oracle Identity Analytics securely with the iPad application.Oracle Identity Management 11g R2 is an important evolutionary release. Oracle's Identity Management suite has more characteristics of a cohesive platform. This platform provides an integrated set of identity services that can be used to protect, manage, and audit security within the enterprise. At HCM we take the platform concept a step further and see it as an opportunity to create unique solutions for Oracle Identity Management customers. IdentityCert is our commitment to this platform. You can download IdentityCert from the Apple iOS App Store today. It includes a demo dataset that you can use to explore the functions of the product without any server infrastructure. Download it. Give it a try. We would appreciate your interest and welcome any feedback.Resources:Press Release: Hub City Media Introduces iPad Application IdentityCert™ for Oracle Identity AnalyticsApp Store Download: http://bit.ly/IdentityCertOracle Identity Governance Suite

• Taking a screenshot from within a Silverlight #WP7 application

  - by Laurent Bugnion

  Often times, you want to take a screenshot of an application’s page. There can be multiple reasons. For instance, you can use this to provide an easy feedback method to beta testers. I find this super invaluable when working on integration of design in an app, and the user can take quick screenshots, attach them to an email and send them to me directly from the Windows Phone device. However, the same mechanism can also be used to provide screenshots are a feature of the app, for example if the user wants to save the current status of his application, etc. Caveats Note the following: The code requires an XNA library to save the picture to the media library. To have this, follow the steps: In your application (or class library), add a reference to Microsoft.Xna.Framework. In your code, add a “using” statement to Microsoft.Xna.Framework.Media. In the Properties folder, open WMAppManifest.xml and add the following capability: ID_CAP_MEDIALIB. The method call will fail with an exception if the device is connected to the Zune application on the PC. To avoid this, either disconnect the device when testing, or end the Zune application on the PC. While the method call will not fail on the emulator, there is no way to access the media library, so it is pretty much useless on this platform. This method only prints Silverlight elements to the output image. Other elements (such as a WebBrowser control’s content for instance) will output a black rectangle. The code public static void SaveToMediaLibrary( FrameworkElement element, string title) { try { var bmp = new WriteableBitmap(element, null); var ms = new MemoryStream(); bmp.SaveJpeg( ms, (int)element.ActualWidth, (int)element.ActualHeight, 0, 100); ms.Seek(0, SeekOrigin.Begin); var lib = new MediaLibrary(); var filePath = string.Format(title + ".jpg"); lib.SavePicture(filePath, ms); MessageBox.Show( "Saved in your media library!", "Done", MessageBoxButton.OK); } catch { MessageBox.Show( "There was an error. Please disconnect your phone from the computer before saving.", "Cannot save", MessageBoxButton.OK); } } This method can save any FrameworkElement. Typically I use it to save a whole page, but you can pass any other element to it. On line 7, we create a new WriteableBitmap. This excellent class can render a visual tree into a bitmap. Note that for even more features, you can use the great WriteableBitmapEx class library (which is open source). On lines 9 to 16, we save the WriteableBitmap to a MemoryStream. The only format supported by default is JPEG, however it is possible to convert to other formats with the ImageTools library (also open source). Lines 18 to 20 save the picture to the Windows Phone device’s media library. Using the image To retrieve the image, simply launch the Pictures library on the phone. The image will be in Saved Pictures. From here, you can share the image (by email, for instance), or synchronize it with the PC using the Zune software. Saving to other platforms It is of course possible to save to other platforms than the media library. For example, you can send the image to a web service, or save it to the isolated storage on the device. To do this, instead of using a MemoryStream, you can use any other stream (such as a web request stream, or a file stream) and save to that instead. Hopefully this code will be helpful to you!

• Architecture/pattern resources for small applications and tools

  - by s73v3r

  I was wondering if anyone had any resources or advice related to using architecture patterns like MVVM/MVC/MVP/etc on small applications and tools, as opposed to large, enterprisy ones. EDIT: Most of the information I see on application architecture is directed at large, enterprise applications. I'm just writing small programs and tools. As far as using these architecture patterns, is it generally worthwhile to go through the overhead of using an MVC/MVVM framework? Or would I be better off keeping it simple?

• How do I write code that doesn't suck? [closed]

  - by Afnan

  My friends and I would like to write a C# desktop application, and would like some guidance on how to make sure the code base is professional and well-kept. Should we use classes or interfaces for our inheritance patterns (which is better)? What are the best practices for professional applications? How do we know what sloppy code looks like, and how do we avoid creating sloppy code? Are there any best practices regarding the design of Winforms applications?

• Server-infrastructure recommendations

  - by Tim van Elsloo

  Here's the thing: I need a cheap, fast, reliable infrastructure that can dynamically scale (like Amazon S3: cloud-storage). I'm thinking of 3 different type of 'servers'. Application-server Should be able to run CentOS (or another light Linux-distr.) Should be able to run Apache Should be able to run PHP Should be able to run GD (so it does rely on it's cpu). Should be extremely reliable and fast. Database-server Should be able to run MySQL Should be able to... well, do nothing else :P. Should be extremely reliable and fast. Storage-server Should be able to run some kind of file-transfer-deamon (like FTP, CouchDB, etc.) Should be able to do nothing else. Should be extremely reliable and fast. So technically, by transferring all static data to 2 different servers/services, the application-server can totally focus on the webpages. My questions: What services do you recommend? Which is cheaper, faster and more reliable: using my own server, or using some cloud-storage/cloud-computing-service (like Amazon S3, CloudFiles, etc.)? How can I prevent bandwidth abuse (such as dos-attacks causing the bill to be extremely high)? What's the difference between "including CDN" and "excluding CDN"? It seems the price doesn't differ at CloudFiles? Do you have to pay "including CDN" + "excluding CDN" when you decide to enable the delivery-network? Or have you only got to pay "including CDN"? Should I use my own nameserver too or can I use my domain-hoster's nameservers? What are the minimum software specifications of a nameserver. Can I write some software myself? Does anyone have a good protocol-description? I hope you can answer my questions. Answers I shouldn't write my own nameserver-software. Instead, I should use something like bind.

• What is the correct way to use g_signal_connect() in C++ for dynamic unity quicklists?

  - by hakermania

  I want to make my application use dynamic unity quicklists. For building my application I am using C++ and the QtCreator IDE. When a menu action is triggered I want to be able to have access to a non-static function of my MainWindow class so as to be able to update the Graphical User Interface which can be accessed from inside 'normal' MainWindow's functions. So, I am building up my quicklist like this (mainwindow.cpp): void MainWindow::enable_unity_quicklist(){ Unity_Menu = dbusmenu_menuitem_new(); dbusmenu_menuitem_property_set_bool (Unity_Menu, DBUSMENU_MENUITEM_PROP_VISIBLE, FALSE); Unity_Stop = dbusmenu_menuitem_new(); dbusmenu_menuitem_property_set(Unity_Stop, DBUSMENU_MENUITEM_PROP_LABEL, "Stop"); dbusmenu_menuitem_child_append (Unity_Menu, Unity_Stop); g_signal_connect (Unity_Stop, DBUSMENU_MENUITEM_SIGNAL_ITEM_ACTIVATED, G_CALLBACK(&fake_callback), (gpointer)this); if(!unity_entry) unity_entry = unity_launcher_entry_get_for_desktop_id("myapp.desktop"); unity_launcher_entry_set_quicklist(unity_entry, Unity_Menu); dbusmenu_menuitem_property_set_bool(Unity_Menu, DBUSMENU_MENUITEM_PROP_VISIBLE, true); dbusmenu_menuitem_property_set_bool(Unity_Stop, DBUSMENU_MENUITEM_PROP_VISIBLE, true); } void MainWindow::fake_callback(gpointer data){ MainWindow* m = (MainWindow*)data; m->on_stopButton_clicked(); } void MainWindow::on_stopButton_clicked(){ //stopping the process... } mainwindow.h: private slots: void enable_unity_quicklist(); void on_stopButton_clicked(); public slots: static void fake_callback(gpointer data); This suggestion was taken from http://old.nabble.com/Using-g_signal_connect-in-class-td18461823.html The program crashes immediately after I choose the 'Stop' action from the Unity Quicklist. Debugging the program shows that I am not able to access anything MainWindow related inside the on_stopButton_clicked() without crashing. For example, it crashes when doing this check (which is the first 2 lines of code inside this function): if (!ui->stopButton->isEnabled()) return; I have also tested lots of other things that I found at the internet, but nothing of them worked. One interesting solution would be to use gtkmm (http://developer.gnome.org/gtkmm-tutorial/stable/sec-connecting-signal-handlers.html.en) but I am not used at all working on GTK applications (I work solely in Qt) and I don't know if this even suits to my occasion. A compilable example indicating what the problem is can be found at: http://ubuntuone.com/7iKA3wnPmWVp8YNNDLlVQI (3.2Kb) If you are not familiar with the QtCreator IDE, you can compile with the following commands, as long as you have all the needed libraries: cd dynamic_unity_quicklists_test; qmake -project; qmake; make

• How to create a GLib.TimeVal from timestamp?

  - by fluteflute

  I have a value such as 'timestamp' below, where the last three digits correspond to milliseconds. timestamp = 1340830988768 I currently have code that looks like the following: import indicate indicator = indicate.Indicator() indicator.set_property_time("time", int(timestamp[:-3])) I want to amend it to use: from gi.repository import Indicate indicator = Indicate.Indicator() However, the new version of set_property_time requires the second parameter to be a GLib.TimeVal. How do I create a GLib.TimeVal from my timestamp? Millisecond precision is not important for this application.

• VB alternative/equivalent for development of Windows apps in Ubuntu

  - by Nirmik

  I want to develop a simple form for an Invoice for the user to use on Windows. I learnt how to do it using Visual basic in Windows. It's the simplest way to make a GUI for Windows I suppose. I am going to link it to a database at the backend. I want an alternative or equivalent software that will provide me with similar drag-and-drop feature enabled programing and GUI designing that will help me crate an application that will run on Windows.

• How to programmatically fetch a list of applications from the Software Center

  - by David Planella

  Im writing a PyGI app where I'd like to show a list of matching applications from the Ubuntu Software Centre in an auto-completion text entry or dropdwon. I haven't yet figured out the best way to present the information, I just want to make it easier for the user to type the name of an application. But before that, I'd like to figure out how to get the data. Is there an API to get a list of all applications from the Software Centre, or indirectly through the Applications Dash in Unity?

• Find version of development library from command line?

  - by mathematician1975

  I installed the c++ boost development libraries using Ubuntu software centre. The problem is that it was quite a long time ago and I cannot remember where they are installed nor what version they were. Is there anything I can do from the command line that will tell me what version(s) I have installed on my system?? I know I can do things like gcc -v to get version of an application but is there a similar thing available for libraries? I am using ubuntu 12.04

• Best way to load application settings

  - by enzom83

  A simple way to keep the settings of a Java application is represented by a text file with ".properties" extension containing the identifier of each setting associated with a specific value (this value may be a number, string, date, etc..). C# uses a similar approach, but the text file must be named "App.config". In both cases, in source code you must initialize a specific class for reading settings: this class has a method that returns the value (as string) associated with the specified setting identifier. // Java example Properties config = new Properties(); config.load(...); String valueStr = config.getProperty("listening-port"); // ... // C# example NameValueCollection setting = ConfigurationManager.AppSettings; string valueStr = setting["listening-port"]; // ... In both cases we should parse strings loaded from the configuration file and assign the ??converted values to the related typed objects (parsing errors could occur during this phase). After the parsing step, we must check that the setting values ??belong to a specific domain of validity: for example, the maximum size of a queue should be a positive value, some values ??may be related (example: min < max), and so on. Suppose that the application should load the settings as soon as it starts: in other words, the first operation performed by the application is to load the settings. Any invalid values for the settings ??must be replaced automatically with default values??: if this happens to a group of related settings, those settings are all set with default values. The easiest way to perform these operations is to create a method that first parses all the settings, then checks the loaded values ??and finally sets any default values??. However maintenance is difficult if you use this approach: as the number of settings increases while developing the application, it becomes increasingly difficult to update the code. In order to solve this problem, I had thought of using the Template Method pattern, as follows. public abstract class Setting { protected abstract bool TryParseValues(); protected abstract bool CheckValues(); public abstract void SetDefaultValues(); /// <summary> /// Template Method /// </summary> public bool TrySetValuesOrDefault() { if (!TryParseValues() || !CheckValues()) { // parsing error or domain error SetDefaultValues(); return false; } return true; } } public class RangeSetting : Setting { private string minStr, maxStr; private byte min, max; public RangeSetting(string minStr, maxStr) { this.minStr = minStr; this.maxStr = maxStr; } protected override bool TryParseValues() { return (byte.TryParse(minStr, out min) && byte.TryParse(maxStr, out max)); } protected override bool CheckValues() { return (0 < min && min < max); } public override void SetDefaultValues() { min = 5; max = 10; } } The problem is that in this way we need to create a new class for each setting, even for a single value. Are there other solutions to this kind of problem? In summary: Easy maintenance: for example, the addition of one or more parameters. Extensibility: a first version of the application could read a single configuration file, but later versions may give the possibility of a multi-user setup (admin sets up a basic configuration, users can set only certain settings, etc..). Object oriented design.

• Exposing BL as WCF service

  - by Oren Schwartz

  I'm working on a middle-tier project which encapsulates the business logic (uses a DAL layer, and serves a web application server [ASP.net]) of a product deployed in a LAN. The BL serves as a bunch of services and data objects that are invoked upon user action. At present times, the DAL acts as a separate application whereas the BL uses it, but is consumed by the web application as a DLL. Both the DAL and the web application are deployed on different servers inside organization, and since the BL DLL is consumed by the web application, it resides in the same server. The worst thing about exposing the BL as a DLL is that we lost track with what we expose. Deployment is not such a big issue since mostly, product versions are deployed together. Would you recommend migrating from DLL to WCF service? if so, why ? Do you know anyone who had a similar experience ? Thank you !

• MSSQL instance shuts down

  - by citronas

  I'm currently developing a new ASP.net project hosted on a Windows Server 2008 RC2 with an MSSQL 2008 Express Database. I have three SQL instances (for different purposes) running which currently all contain a single database. For apprently no reason, these instances tend to shut down after some days, for no apparent reason. There might be low or none traffic to these instances, because there might be some days in a row, where I can't develop. It now occured several times, that one or two of these three instances just shut down, so that I can't access the database, without manually starting the instance. I can't seem to find a event log entry for the shutdown, which is most likely because I just enabled logging (why is the default setting off?) So the questions are: * Why does a SQL instance shut down? (Is there such thing as a "Shut down instance after 3 days of inactivity"? * How can I achieve that the instances are running 24/7?
