• planning the same app for both OSX and iOS

  - by P5music

  I would like to ask which is the best strategy for creating an application that will be developed both on Mac and iPad, so to make minumum effort to port it from one platform to the other, starting from iPad, for example, but rather trying to make both at the same time. The application, in fact, would be an iPad-style one on the Mac too. How should I have to plan the project? Which are the main tricks to easily get the goal?

• The indicator icon of Copy.com disappeared or the menu is unreadable

  - by January

  Copy.com is a commercial service offering free space (much like Dropbox and, once, UbuntuOne). Starting with version 13.10 and continuing with 14.04, two bugs plague the Copy.com application on Ubuntu (see this thread): sometimes, the application indicator is not at all visible even if it is visible, the menu is not readable (no menu entries except for one or two), like this: How can I get rid of these two bugs?

• ASP.NET developers build rich management system using the VWG extension

  - by Visual WebGui

  When The Center for Organ Recovery & Education (CORE) decided they needed a web application to allow easy access to the expenses management system they initially went to ASP.NET web forms combined with CSS. The outcome, however, was not satisfying enough as it appeared bland and lacked in richness. So in order to enrich the UI and give the web application some glitz, Visual WebGui was selected. Visual WebGui provided the needed richness and the familiar Windows look and feel also made the transition...(read more)

• Enabling super single user mode with SQL Server

  - by simonsabin

  I recently got an email from a fellow MVP about single user mode. It made me think about some features I had just been looking at and so I started playing. The annoyance about single user mode for SQL Server is that its not really single user, but more like single connection mode. So how can you get round it, well there is extension to the -m startup option that allows you to specify an application name, and only connections with that application name can connect. This is very useful if you have...(read more)

• Elastic PaaS with WebLogic and OpenStack, part I

  - by Jernej Kaše

  In my previous blog I described the steps to get OpenStack on Solaris up and running. Now we'll explore how WebLogic and OpenStack can work together to deliver truly elastic Middleware Platform as a Service. Middleware / Platform as a Service goals First, let's define what PaaS should be : PaaS offerings facilitate the deployment of applications without the complexity of managing the underlying hardware and software and provisioning hosting capabilities. To break it down: - PaaS provides a complete platform for hosting solutions (Java EE, SOA, BPM, ...) - Infrastructure provisioning (virtual machine, OS, platform) and managing is hidden from the PaaS user [administrator or developer] - Additionally, PaaS could / should define target SLAs, and the platform should ensure the SLAs are meet automatically. PaaS use case To make it more tangible, we have an IT Administrator who has the requirement to deploy a Java EE enterprise application. The application is used by external users who need to submit reports by the end of each month. As a result, the number of concurrent users will fluctuate, with expected huge spikes around the end of each month. The SLA agreed by the management is that no more than 100 requests should be waiting to be processes at any given time. In addition, the IT admin has no more than 3 days to have the platform and the application operational. The Challenges Some of the challenges the IT Administrator is facing are: - how are we going to ensure the processing power? - how are we going to provision the (virtual) machines, Java EE platform and deploy the application? - how are we going to monitor the SLA? - how are we going to react to SLA, and increase capacity?  The Ideal Solution Ideally, the whole process should be automated, "set it and forget" and require no human interaction: - The vendor packages the solution as deployable image(s) - The images are deployed to the IaaS - From there, automated processes take care of SLA  Solution Architecture with WebLogic 12c, Dynamic Clusters, OpenStack & Solaris OracleSolaris provides OS and virtualisation through Solaris Zones OpenStack is a part of Solaris 11.2 and provides Cloud Management (console and API) WebLogic 12c with Dynamic Clusters provides the Platform Trafic Manager provides load balancing On top of out that, we are going to implement a small control script - Cloud Manager - which is going to monitor SLA through WebLogic Diagnostic Framework. In case there are more than 100 pending requests, the script will: - provision a new virtual machine based on image which is configured for the WebLogic domain - add the machine to WebLogic domain - Increase the number of servers in dynamic cluster - Start the newly provisioned server  Stay tuned for part II The hole solution with working demo will be presented in one of our Partner WebCasts in June, exact date TBA. Jernej Kaše is a Fusion Middleware Specialist working closely with Oracle Partners in the ECEMEA region to grow their business by leveraging Oracle technology.

• Rewrote GNU GPL v2 code in another language: can I change a license?

  - by Anton Gogolev

  I rewrote some parts of Mercurial (which is licensed under GNU GPL v2) in C#. Naturally, I looked a lot into original Python code and some parts are direct translations from Python to C#. Is is possible have "my code" licensed under different terms or to even make a part of a closed-source commercial application? If not, can I re-license "my-code" under LGPL, open-source it and then use this open-sourced C# library in my closed-source commercial application?

• The 20 Most Important Keyboard Shortcuts For Windows PCs

  - by Chris Hoffman

  Keyboard shortcuts are practically essential for using any type of PC. They’ll speed up almost everything you do. But long lists of keyboard shortcuts can quickly become overwhelming if you’re just getting started. This list will cover the most useful keyboard shortcuts that every Windows user should know. If you haven’t used keyboard shortcuts much, these will show you just how useful keyboard shortcuts can be. Windows Key + Search The Windows key is particularly important on Windows 8 — especially before Windows 8.1 — because it allows you to quickly return to the Start screen. On Windows 7, it opens the Start menu. Either way, you can start typing immediately after you press the Windows key to search for programs, settings, and files. For example, if you want to launch Firefox, you can press the Windows key, start typing the word Firefox, and press Enter when the Firefox shortcut appears. It’s a quick way to launch programs, open files, and locate Control Panel options without even touching your mouse and without digging through a cluttered Start menu. You can also use the arrow keys to select the shortcut you want to launch before pressing Enter. Copy, Cut, Paste Copy, Cut, and Paste are extremely important keyboard shortcuts for text-editing. If you do any typing on your computer, you probably use them. These options can be accessed using the mouse, either by right-clicking on selected text or opening the application’s Edit menu, but this is the slowest way to do it. After selecting some text, press Ctrl+C to copy it or Ctrl+X to cut it. Position the cursor where you want the text and use Ctrl+V to paste it. These shortcuts can save you a huge amount of time over using the mouse. Search the Current Page or File To quickly perform a search in the current application — whether you’re in a web browser, PDF viewer, document editor, or almost any other type of application — press Ctrl+F. The application’s search (or “Find”) feature will pop up, and you can instantly start typing a phrase you want to search for. You can generally press Enter to  go to the next appearance of the word or phrase in the document, quickly searching through it for what you’re interested in. Switch Between Applications and Tabs Rather than clicking buttons on your taskbar, Alt+Tab is a very quick way to switch between running applications. Windows orders the list of open windows by the order you accessed them, so if you’re only using two different applications, you can just press Alt+Tab to quickly switch between them. If switching between more than two windows, you’ll have to hold the Alt key and press Tab repeatedly to toggle through the list of open windows. If you miss the window you want, you can always press Alt+Shift+Tab to move through the list in reverse. To move between tabs in an application — such as the browser tabs in your web browser — press Ctrl+Tab. Ctrl+Shift+Tab will move through tabs in reverse. Quickly Print If you’re the kind of person who still prints things, you can quickly open the print window by pressing Ctrl+P. This can be faster than hunting down the Print option in every program you want to print something from. Basic Browser Shortcuts Web browser shortcuts can save you tons of time, too. Ctrl+T is a very useful one, as it will open a new tab with the address bar focused, so you can quickly press Ctrl +T, type a search phrase or web address, and press Enter to go there. To go back or forward while browsing, hold the Ctrl key and press the left or right arrow keys. If you’d just like to focus your web browser’s address bar so you can type a new web address or search without opening a new tab, press Ctrl + L. You can then start typing something and press Enter. Close Tabs and Windows To quickly close the current application, press Alt+F4. This works on the desktop and even in new Windows 8-style applications. To quickly close the current browser tab or document, press Ctrl+W. This will often close the current window if there are no other tabs open. Lock Your Computer When you’re done using your computer and want to step away, you may want to lock it. People won’t be able to log in and access your desktop unless they know your password. You can do this from the Start menu or Start screen, but the fastest way to lock your screen is by quickly pressing Windows Key + L before you get up. Access the Task Manager Ctrl+Alt+Delete will take you to a screen that allows you to quickly launch the Task Manager or perform other operations, such as signing out. This is particularly useful because if can be used to recover from situations where your computer doesn’t appear responsive or isn’t accepting input. For example, if a full-screen game becomes unresponsive, Ctrl+Alt+Delete will often allow you to escape from it and end it via the Task Manager. Windows 8 Shortcuts On Windows 8 PCs, there are other very important keyboard shortcuts. Windows Key + C will open your Charms bar, while Windows Key + Tab will open the new App Switcher. These keyboard shortcuts will allow you to avoid the hot corners, which can be tedious to use with a mouse. On the desktop side, Windows Key + D will take you back to the desktop from anywhere. Windows Key + X will open a special “power user menu” that gives you quick access to options that are hidden in the new Windows 8 interface, including Shut Down, Restart, and Control Panel. If you’re interested in learning more keyboard shortcuts, be sure to check our longer lists of 47 keyboard shortcuts that work in all web browsers and 42+ keyboard shortcuts to speed up text-editing.

• Script For Detecting Availability of XMLHttp in Internet Explorer

  - by Duncan Mills

  Having the XMLHttpRequest API available is key to any ADF Faces Rich Client application. Unfortunately, it is possible for users to switch off this option in Internet Explorer as a Security setting. Without XMLHttpRequest available, your ADF Faces application will simply not work correctly, but rather than giving the user a bad user experience wouldn't it be nicer to tell them that they need to make some changes in order to use the application?  Thanks to Blake Sullivan in the ADF Faces team we now have a little script that can do just this. The script is available from https://samplecode.oracle.com here - The attached file browserCheck.js is what you'll need to add to your project.The best way to use this script is to make changes to whatever template you are using for the entry points to your application. If you're not currently using template then you'll have to make the same change in each of your JSPX pages. Save the browserCheck.js file into a /js/ directory under your HTML root within your UI project (e.g. ViewController)In the template or page, select the <af:document> object in the Structure window. From the right mouse (context) menu choose Facet and select the metaContainer facet.Switch to the source code view and locate the metaContainer facet. Then insert the following lines (I've included the facet tag for clarity but you'll already have that):      <f:facet name="metaContainer">        <af:resource type="javascript"                      source="/js/browserCheck.js"/>        <af:resource type="javascript">           xmlhttpNativeCheck(                     "help/howToConfigureYourBrowser.html");        </af:resource>      </f:facet>Note that the argument to the xmlhttpNativeCheck function is a page that you want to show to the user if they need to change their browser configuration. So build this page in the appropriate place as well. You can also just call the function without any arguments e.g. xmlhttpNativeCheck(); in which case it will pop up default instructions for the user to follow, but not redirect to any other page.

• screen DPI - is there and equivalent command/action to Windows 150% Display

  - by Yekhezkel Yovel

  I have a wide screen of high resolution and I see everything small on it. So In windows I set the display to 150%, I would like to do something similar in Ubuntu. Simply changing screen resolution to lower resolution doesn't help because Ubuntu is in a virtual machine and it simply changes the VM window to the actual resolution. Is there a command or a simple hack that can do the trick? EDIT: I am running Ubuntu as a VirtualBox VM on Windows 7 host.

• Answers to Your Common Oracle Database Lifecycle Management Questions

  - by Scott McNeil

  We recently ran a live webcast on Strategies for Managing Oracle Database's Lifecycle. There were tons of questions from our audience that we simply could not get to during the hour long presentation. Below are some of those questions along with their answers. Enjoy! Question: In the webcast the presenter talked about “gold” configuration standards, for those who want to use this technique, could you recommend a best practice to consider or follow? How do I get started? Answer:Gold configuration standardization is a quick and easy way to improve availability through consistency. Start by choosing a reference database and saving the configuration to the Oracle Enterprise Manager repository using the Save Configuration feature. Next create a comparison template using the Oracle provided template as a starting point and modify the ignored properties to eliminate expected differences in your environment. Finally create a comparison specification using the comparison template you created plus your saved gold configuration and schedule it to run on a regular basis. Don’t forget to fill in the email addresses of those you want to notify upon drift detection. Watch the database configuration management demo to learn more. Question: Can Oracle Lifecycle Management Pack for Database help with patching an Oracle Real Application Cluster (RAC) environment? Answer: Yes, Oracle Enterprise Manager supports both parallel and rolling patch application of Oracle Real Application Clusters. The use of rolling patching is recommended as there is no downtime involved. For more details watch this demo. Question: What are some of the things administrators can do to control configuration drift? Why is it important? Answer:Configuration drift is one of the main causes of instability and downtime of applications. Oracle Enterprise Manager makes it easy to manage and control drift using scheduled configuration comparisons combined with comparison templates. Question: Does Oracle Enterprise Manager 12c Release 2 offer an incremental update feature for "gold" images? For instance, if the source binary has a higher PSU level, what is the best approach to update the existing "gold" image in the software library? Do you have to create a new image or can you just update the original one? Answer:Provisioning Profiles (Gold images) can contain the installation files and database configuration templates. Although it is possible to make some changes to the profile after creation (mainly to configuration), it is normally recommended to simply create a new profile after applying a patch to your reference database. Question: The webcast talked about enforcing in-house standards, does Oracle Enterprise Manager 12c offer verification of your databases and systems to those standards? For example, the initial "gold" image has been massively deployed over time, and there may be some changes to it. How can you do regular checks from Enterprise Manager to ensure the in-house standards are being enforced? Answer:There are really two methods to validate conformity to standards. The first method is to use gold standards which you compare other databases to report unwanted differences. This method uses a new comparison template technology which allows users to ignore known differences (i.e. SID, Start time, etc) which results in a report only showing important or non-conformant differences. This method is quick to setup and configure and recommended for those who want to get started validating compliance quickly. The second method leverages the new compliance framework which allows the creation of specific and robust validations. These compliance rules are grouped into standards which can be assigned to databases quickly and easily. Compliance rules allow for targeted and more sophisticated validation beyond the basic equals operation available in the comparison method. The compliance framework can be used to implement just about any internal or industry standard. The compliance results will track current and historic compliance scores at the overall and individual database targets. When the issue is resolved, the score is automatically affected. Compliance framework is the recommended long term solution for validating compliance using Oracle Enterprise Manager 12c. Check out this demo on database compliance to learn more. Question: If you are using the integration between Oracle Enterprise Manager and My Oracle Support in an "offline" mode, how do you know if you have the latest My Oracle Support metadata? Answer:In Oracle Enterprise Manager 12c Release 2, you now only need to download one zip file containing all of the metadata xmls files. There is no indication that the metadata has changed but you could run a checksum on the file and compare it to the previously downloaded version to see if it has changed. Question: What happens if a patch fails while administrators are applying it to a database or system? Answer:A large portion of Oracle Enterprise Manager's patch automation is the pre-requisite checks that happen to ensure the highest level of confidence the patch will successfully apply. It is recommended you test the patch in a non-production environment and save the patch plan as a template once successful so you can create new plans using the saved template. If you are using the recommended ‘out of place’ patching methodology, there is no urgency because the database is still running as the cloned Oracle home is being patched. Users can address the issue and restart the patch procedure at the point it left off. If you are using 'in place' method, you can address the issue and continue where the procedure left off. Question: Can Oracle Enterprise Manager 12c R2 compare configurations between more than one target at the same time? Answer:Oracle Enterprise Manager 12c can compare any number of target configurations at one time. This is the basis of many important use cases including Configuration Drift Management. These comparisons can also be scheduled on a regular basis and emails notification sent should any differences appear. To learn more about configuration search and compare watch this demo. Question: How is data comparison done since changes are taking place in a live production system? Answer:There are many things to keep in mind when using the data comparison feature (as part of the Change Management ability to compare table data). It was primarily intended to be used for maintaining consistency of important but relatively static data. For example, application seed data and application setup configuration. This data does not change often but is critical when testing an application to ensure results are consistent with production. It is not recommended to use data comparison on highly dynamic data like transactional tables or very large tables. Question: Which versions of Oracle Database can be monitored through Oracle Enterprise Manager 12c? Answer:Oracle Database versions: 9.2.0.8, 10.1.0.5, 10.2.0.4, 10.2.0.5, 11.1.0.7, 11.2.0.1, 11.2.0.2, 11.2.0.3.

• A big flat text file or a HTML site for language documentation?

  - by Bad Sector

  A project of mine is a small embeddable Tcl-like scripting language, LIL. While i'm mostly making it for my own use, i think it is interesting enough for others to use, so i want it to have a nice (but not very "wordy") documentation. So far i'm using a single flat readme.txt file. It explains the language's syntax, features, standard functions, how to use the C API, etc. Also it is easy to scan and read in almost every environment out there, from basic text-only terminals to full-fledged high-end graphical desktop environments. However, while i tried to keep things nicely formatted (as much as this is possible in plain text), i still think that being a big (and growing) wall of text, it isn't as easy on the eyes as it could be. Also i feel that sometimes i'm not writing as much as i want in order to avoid expanding the text too much. So i thought i could use another project of mine, QuHelp, which is basically a help site generator for sites like this one with a sidebar that provides a tree of topics/subtopics and offline full text search. With this i can use HTML to format the documentation and if i use QuHelp for some other project that uses LIL, i can import LIL's documentation as part of the other project's documentation. However converting the existing documentation to QuHelp/HTML isn't a small task, especially when it comes to functions (i'll need to put more detail on them than what currently exists in the readme.txt file). Also it loses the wide range of availability that it currently has (even if QuHelp's generated code degrades gracefully down to console-only web browsers, plain text is readable from everywhere, including from popular editors such as Vim and Emacs - i had someone once telling me that he likes LIL's documentation because it is readable without leaving his editor). So, my question is simply this: should i keep the documentation as it is now in the form of a single readme.txt file or should i convert it to something like the site i mentioned above? There is also the option to do both, but i'm not sure if i'll be able to always keep them in sync or if it is worth the effort. After asking around in IRC i've got mixed answers: some liked the wide availability of the single text file, others said that it is looks as bad as a man page (personally i don't mind that - i can read man pages just fine - but other people might have issues reading them). What do you think?

• BPM ADF Task forms. Checking whether the current user is in a BPM Swimlane

  - by Christopher Karl Chan

  @page { margin: 0.79in } P { margin-bottom: 0.08in } --Focus So this blog entry will focus on BPM Swimlane roles and users from a ADF context. So we have an ADF Task Details Form and we are in the process of making it richer and dynamic in functionality. A common requirement could be to dynamically show different areas based on the user logged into the workspace. Perhaps even we want to know even what swim-lane role the user belongs to. It is is a little bit harder to achieve then one thinks unless you know the trick. The Challenge The tricky part here is that the ADF Task Details Form is in fact part of a separate J2EE application to the main workspace. So if you try to use Java or Expression Language to get the logged in user you will only find anonymous and none of the BPM Roles you will be expecting. So what to do? The Magic First add the BC4J Security library to your view project. Then Restart JDeveloper. Now find the web.xml file in the view project of your ADF Task Details Application and look for the JpsFilter section. Then add in the following section. <init-param> <param-name>application.name</param-name> <param-value>OracleBPMProcessRolesApp</param-value></init-param> This will link your application to that of the BPM workspace. Then in your dynamic part of your ADF form you can now check whether the user logged into the BPM Workspace belongs in a BPM swim-lane in any BPM process. The best way to do this is by using expression language in the JSF page itself. Here I am simply changing the rendered flag to either true or false and thereby hiding or showing a section. Perhaps you are re-using the same form for a task in an approver swim-lane and ordinary user swimlane. So we only want the approver to see this field. So call the built in function to check if the user is a member of the BPM swim-lane role. The name of the role must be of the syntax BPMProject.RoleName <af:outputText value="This will only be rendered when the user is part of the BPM Swimlane Role rendered="#{securityContext.userInRole['BPMProjectName.Rolename']}"/> Now you must redeploy your ADF Task Form project Now (in the image above) the text will ONLY get rendered in the Task Details Form only if the user logged into the workspace is a member of the swimlane Unsecure of the BPM project SimpleTask

• How much freedom should a programmer have in choosing a language and framework?

  - by Spencer

  I started working at a company that is primarily a C# oriented. We have a few people who like Java and JRuby, but a majority of programmers here like C#. I was hired because I have a lot of experience building web applications and because I lean towards newer technologies like JRuby on Rails or nodejs. I have recently started on a project building a web application with a focus on getting a lot of stuff done in a short amount of time. The software lead has dictated that I use mvc4 instead of rails. That might be OK, except I don't know mvc4, I don't know C# and I am the only one responsible for creating the web application server and front-end UI. Wouldn't it make sense to use a framework that I already know extremely well (Rails) instead of using mvc4? The two reasons behind the decision was that the tech lead doesn't know Jruby/rails and there would be no way to reuse the code. Counter arguments: He won't be contributing to the code and is frankly, not needed on this project. So, it doesn't really matter if he knows JRuby/rails or not. We actually can reuse the code since we have a lot of java apps that JRuby can pull code from and vice-versa. In fact, he has dedicated some resources to convert a Java library to C#, instead of just running the Java library on the JRuby on Rails app. All because he doesn't like Java or JRuby I have built many web applications, but using something unfamiliar is causing some spin-up and I am unable to build an awesome application in as short of a time that I'm used to. This would be fine, learning new technologies is important in this field. The problem is, for this project, we need to get a lot done in a short period of time. At what point should a developer be allowed to choose his tools? Is this dependent on the company? Does my company suck or is this considered normal? Do greener pastures exist? Am I looking at this the wrong way? Bonus: Should I just keep my head down and move along at a snails pace, or defy orders and go with what I know in order to make this project more successful? Edit: I had actually created a fully function rails application (on my own time) and showed it to the team and it did not seem to matter. I am currently porting it to mvc4 (slowly).
