  • Visual Studio 2010 plus Help Index : have your cake and eat it too

    - by Adrian Hara
    Although the team's intentions might have been good, the new help system in Visual Studio 2010  is a huge step backwards (more like a cannonball-shot-kind-of-leap really) from the one we all know (and love?) in Visual Studio 2008 and 2005 (and heck, even VS6). Its biggest problem, from my point of view, is the total and complete lack of the Help Index feature: you know...the thing where you just go and type in what you're looking for and it filters down the list of results automatically. For me this was the number one productivity feature in the "old" help system, allowing me to find stuff very quickly. Number two is that it's entirely web based and runs, by default, in the browser. So imagine, when you press F1, a new tab opens in your default browser pointing to the help entry. While this is wrong in many ways, it's also extremely annoying, cleaning up tabs in the browser becomes a chore which represents a serious productivity hit. These and many other problems were discussed extensively (and rather vocally) on connect but it seems MS seemed to ignore it and opt to release the new help system anyway, with the promise that more features will be added in a later release. Again, it kind of amazes me that they chose to ship a product with LESS features that the previous one and, what's worse, missing KEY features, just so it's "standards based" and "extensible". To be honest, I couldn't care less about the help system's implementation, I just want it to be usable and I would've thought that by now the software community and especially MS would've learned this lesson. In the end, what kind of saddens me is that MS regards these basic features as ones for the "power help user". I mean, come on! I mean a) it's not like my aunt's using Visual Studio 2010 and she represents the regular user, b) all software developers are, by definition, power users and c) it's a freakin help, not rocket science! As you can tell, I'm pretty pissed. Even more so because I really feel that the VS2010 & co. release really is a great one, with a lot of effort going into the various platforms and frameworks, most (if not all) of them being really REALLY good products. And then they go and screw up the help! How lame is that?!   Anyway, it's not all gloom-and-doom. Luckily there is a desktop app which presents a UI over the new help system that's very close to what was there in VS2008, by Robert Chandler (to which I hereby declare eternal gratitude). It still has some minor issues but I'll take it over the browser version of the help any day. It's free, pretty quick (on my machine ;)) and nicely usable. So, if you hate the new help system (passionately) like I do, download H3Viewer now.

  • Programming Windows 8 Apps with HTML, CSS, and JavaScript - All you need in one title

    It took me a while to work through the 800+ pages of this title. And yes, I really mean working not reading... Since the release of Windows 8 it should be obvious to any Windows software developer that there are new ways to develop, deploy and market applications for a broader audience. Interestingly, Microsoft started to narrow the technological gap between the various platforms - desktop, web, smartphone and XBox - and development of modern apps with HTML, CSS and JavaScript couldn't be easier. Kraig covers all facets of modern Windows 8 apps from the basic building blocks and project templates in Visual Studio 2012 over to the thoughtful use of specific APIs to finally proper deployment in the App Store and potential monetization. The organisation of the book is lied out like step by step instructions or a tutorial. Kraig literally takes the reader by the hand and explains in detail in his examples about the reasons, the pros, and the cons of a certain way of implementation. Thanks to cross-references to other chapters he leaves the choice to the reader to dig deeper right now or to catch up at some time later. Personally, I have to admit that I really enjoyed the relaxed writing style. App development is not dust-dry rocket science and it should be joyful to learn about new technologies. And thanks to the richness of the various chapters and samples you could easily adapt and transfer the knowledge gained in this title to other platforms like Windows Phone 8. And last but not least: The ebook is freely available at Amazon, Microsoft Press and O'Reilly. Don't think about it, just get the book. Now. Update: I already mentioned this title in other blog entries which are related to Microsoft certification. Feel free to read on and to discover more online resources: Learning content for MCSDs: Web Applications and Windows Store Apps using HTML5 More content for MCSDs: Web Applications and Windows Store Apps using HTML5 O'Reilly offers free webcasts on their site, too. And in case that you would like to know more about Kraig's book and his experience with various development teams, please checkout this one: Zero to App in Two Weeks: Programming Windows 8 Apps in HTML, CSS, and JavaScript. The recording should be available soon.

  • Boot Problem in Asus EEE PC 1015CX

    - by Sâmrat VikrãmAdityá
    I am a newbie to Linux world, although I have previously worked on Ubuntu 11.04 for daily use (Net Access and simple recordings using Audacity). I am not sure, at what level I stand as a newbie. I bought this Asus Eee PC two days back. The model is Asus 1015CX. See the specs here http://www.flipkart.com/asus-1015cx-blk011w-laptop-2nd-gen-atom-dual-core-1gb-320gb-linux/p/itmd8qu4quzu8srr . I created a live USB to install 12.10. The usb booted fine. When I clicked "Try Ubuntu" option, it showed me a black screen with a cursor blinking. I waited for 15 minutes and had to restart using the power button. On clicking the "Install Ubuntu" button, the install process went seamlessly. [I have a Windows7 installed on one of the partitions]. i installed it alongside previous windows installation. The system was then rebooted for the first time. It showed the GRUB menu and I selected the first option Ubuntu. After showing the splash screen for a second, it began showing various messages on a black screen and then it struck on "Stopping Save kernel state message". I had to force shut the system using power button. Sometimes it just gives a blank screen with a cursor blinking and on pressing power button, some messages stating that acpid is doing something and stopping services pops up and the system shuts down. I tried booting with "nomodeset" and other parameters as directed in solution to previous such problems on forums. Also Ctrl+Alt+F1,F2,F3,F4,F5,F6..F12 is not doing anything for me anywhere. At installation, I checked Login automatically option. On booting into recovery several options comes up. Clicking resume just gives me a blank screen with cursor blinking. on dropping to root shell and remounting filesystem as RW, I am able to supply some command that worked for others. startx -- Several messages comes up with last one stating Fatal error: No screen found sudo service lightdm start -- Gives a blank screen with a cursor blinking lspci | grep VGA -- Shows some Intel Integrated Graphic... something I don't remember I had reconfigured xserver-xorg, lightdm, reinstalled ubuntu-desktop, unity. What should I do..?? Will going back to 11.04 work..?? Or I should leave all hopes of running Ubuntu on my netbook. Please help.

  • Oracle Developer Day, Poland, 2012

    - by Geertjan
    Oracle Developer Day took place in Poland today. Oracle's Gregor Rayman did the keynote, where NetBeans was positioned, yet again, as Oracle's IDE for the Java Platform, via the JavaFX Roadmap: Well, it's not so clear from my pic above, but NetBeans is closely tied to the JavaFX Roadmap, as well as the JDK Roadmap too. Then the tracks started, one of which was the Java Track (the other two tracks were on ADF/WebLogic and SOA/BPM/BAM), where among other things I demonstrated the Java EE 6 Platform via tools in NetBeans IDE at some length. The room could hardly have been fuller, chairs had to be brought in and people were standing along the walls. The above pic shows the session being set up, with the room full of developers ready to hear about Java EE 6. I also did a session on pluggable Java desktop development (i.e., NetBeans Platform) and on "What's New in NetBeans IDE 7.1?", while Martin Grebac had a session on Java EE Web Services. Some of the many questions asked during the day that I thought were interesting: Is there localization support for the @Pattern annotation? I.e., what if I want to display the error message in Polish, what do I do? Is there filtering/sorting support for the DataTable component in JSF? Why is there no visual editor for ejb-jar.xml, in the same way that there is for web.xml? "Would be handy if there were to be a JSR for IDE Keyboard Shortcuts." (Two different people asked this question, separately, without knowing about each other. The second didn't know about the Eclipse and IntelliJ keyboard shortcut support in NetBeans IDE and was happy when I told them about it.) Wouldn't it be cool if, on start up, or during installation, there'd be a question: "Are you migrating from Eclipse/IntelliJ?" Then, if "yes", reset the keyboard shortcuts to match the IDE they're coming from.Is there a way in NetBeans to find subclasses of a class? "Would be cool if HTML or JSF files could be visualized in the same way as JavaFX and Swing classes." I.e., Visual Debugger for web developers. I had a great day and am looking at the Oracle Developer Day that will be held in Cluj, Romania, on Friday.

  • ArchBeat Link-o-Rama Top 10 for November 1, 2012

    - by Bob Rhubart
    Hurricane Sandy Edition Power outages in the Cleveland area made it impossible to publish posts on Tuesday and Wednesday. In my neighborhood most are still without power. The sound of howling winds that dominated on Monday and Tuesday has been replaced by the sound of of portable generators. My internet connection was restored only after AT&T U-Verse crewmen hooked up a portable generator to power the relay station up the street. Bear in mind that Cleveland is 500 miles from the Atlantic coast. Mobile Development Platform Strategy Chart: ADF Mobile, WebCenter Sites, Portal, Content and Social "Unlike desktop web focused efforts, the world of mobile has undergone change at a feverish pace," says social enterprise expert John Brunswick. His extensive post charts various resources that will help you keep up. ADF Essentials - The Bare Necessities | Floyd Teter The experiment is over... And now Oracle ACE Director Floyd Teter shares his impressions after spending some time with Oracle ADF Essentials, the free version of Oracle ADF. Expanding the Oracle Enterprise Repository with functional documentation Capgemini middleware specialist Marc Kuijpers shares information on how Oracle Enterprise Repository can be configured "to contain functional assets, i.e. functional designs, use cases and a logical data model" to aid in SOA governance efforts. A review of Oracle SOA Suite 11g Administrator’s Handbook | RedStack "More so than any other single piece of content that I have seen on the topic, it provides the information that a SOA administrator needs to know in order to successfully configure, manage, monitor, troubleshoot and backup an Oracle SOA environment."

  • Why learn Flash Builder 4 (Flex) when I can just use Flash Professional?

    - by Jason McKenna
    I want to learn Flash Builder 4 (Flex) because I see sooo many jobs requesting experience with it. i also just like knowing stuff. I am also very interested in focusing on RIA development now. BUT... can anyone tell me CLEARLY why the heck I would ever use FLEX over Flash Pro?? it is a time investment, so is it worth it? All I read are misguided posts about how Flash Pro is for games and banner ads, and Flex is for programmers and RIAs blah blah... this simply isn't so from my 9 years of contracting experience. I'm 99.9% certain that I can build anything a flex developer can build, but using Flash Pro. I can build powerful AS3-driven apps for the desktop, mobile device, or browser, and I can link to databases with XML and I can import text files and communicate with ColdFusion and everything. The advantage with Flash Pro is that I can also easily and clearly animate transitions and build custom elements that look the way I want/need them to look for my specific client. Why would I want to use a bunch of pre-built components that drive my file sizes to the moon?? Who is happy with a drag-n-drop button?? Is Flex just a thing made for programmer people with no artistic inclination? What is the advantage of using it?? It takes me back to Visual Basic class. Seems like a pain to have to use multiple tools to import crap from Flash Pro into Flex and yada yada... why when I can do it all nicely in Flash Pro to begin with. Am I clueless, or missing some major piece of the puzzle? Thanks for any clarity. PS, I couldn't care less about the code editors. It aint that bad people. They make it out like the thing doesn't even respond to keyboard input or something. Does everthing I need it do anyways. Please help out here. If I just dont need to learn it, I dont want to waste the time. Jase

  • Extensible Metadata in Oracle IRM 11g

    - by martin.abrahams
    Another significant change in Oracle IRM 11g is that we now use XML to create the tamperproof header for each sealed document. This article explains what this means, and what benefit it offers. So, every sealed file has a metadata header that contains information about the document - its classification, its format, the user who sealed it, the name and URL of the IRM Server, and much more. The IRM Desktop and other IRM applications use this information to formulate the request for rights, as well as to enhance the user experience by exposing some of the metadata in the user interface. For example, in Windows explorer you can see some metadata exposed as properties of a sealed file and in the mouse-over tooltip. The following image shows 10g and 11g metadata side by side. As you can see, the 11g metadata is written as XML as opposed to the simple delimited text format used in 10g. So why does this matter? The key benefit of using XML is that it creates the opportunity for sealing applications to use custom metadata. This in turn creates the opportunity for custom classification models to be defined and enforced. Out of the box, the solution uses the context classification model, in which two particular pieces of metadata form the basis of rights evaluation - the context name and the document's item code. But a custom sealing application could use some other model entirely, enabling rights decisions to be evaluated on some other basis. The integration with Oracle Beehive is a great example of this. When a user adds a document to a Beehive workspace, that document can be automatically sealed with metadata that represents the Beehive security model rather than the context model. As a consequence, IRM can enforce the Beehive security model precisely and all rights configuration can actually be managed through the Beehive UI rather than the IRM UI. In this scenario, IRM simply supports the Beehive application, seamlessly extending Beehive security to all copies of workspace documents without any additional administration. Finally, I mentioned that the metadata header is tamperproof. This is obviously to stop a rogue user modifying the metadata with a view to gaining unauthorised access - reclassifying a board document to a less sensitive classifcation, for example. To prevent this, the header is digitally signed and can only be manipulated by a suitably authorised sealing application.

  • The Diabolical Developer: What You Need to Do to Become Awesome

    - by Tori Wieldt
    Wearing sunglasses and quite possibly hungover, Martijn Verburg's evil persona provided key tips on how to be a Diabolical Developer. His presentation at TheServerSide Java Symposium was heavy on the sarcasm and provided lots of laughter. Martijn insisted that developers take their power back and get rid of all the "modern fluff" that distract developers.He provided several key tips to become a Diabolical Developer:*Learn only from yourself. Don't read blogs or books, and don't attend conferences. If you must go on forums, only do it display your superiority, answer as obscurely as possible.*Work aloneBest coding happens when you alone in your room, lock yourself in for days. Make sure you have a gaming machine in with you.*Keep information to yourselfKnowledge is power. Think job security. Never provide documentation. *Make sure only you can read your code.Don't put comments in your code. Name your variables A,B,C....A1,B1, etc.If someone insists you format your in a standard way, change a small section and revert it back as soon as they walk away from your screen. *Stick to what you knowStay on Java 1.3. Don't bother learning abstractions. Write your application in a single file. Stuff as much code into one class as possible, a 30,000-line class is fine. Makes it easier for you to read and maintain.*Use Real ToolsNo "fancy-pancy" IDEs. Real developers only use vi.*Ignore FadsThe cloud is massively overhyped. Mobile is a big fad for young kids.The big, clunky desktop computer (with a real keyboard) will return.Learn new stuff only to pad your resume. Ajax is great for that. *Skip TestingTest-driven development is a complete waste of time. They sent men to the moon without unit tests.Just write your code properly in the first place and you don't need tests.*Compiled = Ship ItUser acceptance testing is an absolute waste of time. *Use a Single ThreadDon't use multithreading. All you need to do is throw more hardware at the problem.*Don't waste time on SEO.If you've written the contract correctly, you are paid for writing code, not attracting users.You don't want a lot of users, they only report problems. *Avoid meetingsFake being sick to avoid meetings. If you are forced into a meeting, play corporate bingo.Once you stand up and shout "bingo" you will kicked out of the meeting. Job done.Follow these tips and you'll be well on your way to being a Diabolical Developer!

  • Multiple render targets and gamma correctness in Direct3D9

    - by Mario
    Let's say in a deferred renderer when building your G-Buffer you're going to render texture color, normals, depth and whatever else to your multiple render targets at once. Now if you want to have a gamma-correct rendering pipeline and you use regular sRGB textures as well as rendertargets, you'll need to apply some conversions along the way, because your filtering, sampling and calculations should happen in linear space, not sRGB space. Of course, you could store linear color in your textures and rendertargets, but this might very well introduce bad precision and banding issues. Reading from sRGB textures is easy: just set SRGBTexture = true; in your texture sampler in your HLSL effect code and the hardware does the conversion sRGB-linear for you. Writing to an sRGB rendertarget is theoretically easy, too: just set SRGBWriteEnable = true; in your effect pass in HLSL and your linear colors will be converted to sRGB space automatically. But how does this work with multiple rendertargets? I only want to do these corrections to the color textures and rendertarget, not to the normals, depth, specularity or whatever else I'll be rendering to my G-Buffer. Ok, so I just don't apply SRGBTexture = true; to my non-color textures, but when using SRGBWriteEnable = true; I'll do a gamma correction to all the values I write out to my rendertargets, no matter what I actually store there. I found some info on gamma over at Microsoft: http://msdn.microsoft.com/en-us/library/windows/desktop/bb173460%28v=vs.85%29.aspx For hardware that supports Multiple Render Targets (Direct3D 9) or Multiple-element Textures (Direct3D 9), only the first render target or element is written. If I understand correctly, SRGBWriteEnable should only be applied to the first rendertarget, but according to my tests it doesn't and is used for all rendertargets instead. Now the only alternative seems to be to handle these corrections manually in my shader and only correct the actual color output, but I'm not totally sure, that this'll not have any negative impact on color correctness. E.g. if the GPU does any blending or filtering or multisampling after the Linear-sRGB conversion... Do I even need gamma correction in this case, if I'm just writing texture color without lighting to my rendertarget? As far as I know, I DO need it because of the texture filtering and mip sampling happening in sRGB space instead, if I don't correct for it. Anyway, it'd be interesting to hear other people's solutions or thoughts about this.

  • Compute directional light frustum from view furstum points and light direction

    - by Fabian
    I'm working on a friends engine project and my task is to construct a new frustum from the light direction that overlaps the view frustum and possible shadow casters. The project already has a function that creates a frustum for this but its way to big and includes way to many casters (shadows) which can't be seen in the view frustum. Now the only parameter of this function are the normalized light direction vector and a view class which lets me extract the 8 view frustum points in world space. I don't have any additional infos about the scene. I have read some of the related Questions here but non seem to fit very well to my problem as they often just point to cascaded shadow maps. Sadly i can't use DX or openGl functions directly because this engine has a dedicated math library. From what i've read so far the steps are: Transform view frustum points into light space and find min/max x and y values (or sometimes minima and maxima of all three axis) and create a AABB using the min/max vectors. But what comes after this step? How do i transform this new AABB back to world space? What i've done so far: CVector3 Points[8], MinLight = CVector3(FLT_MAX), MaxLight = CVector3(FLT_MAX); for(int i = 0; i<8;++i){ Points[i] = Points[i] * WorldToShadowMapMatrix; MinLight = Math::Min(Points[i],MinLight); MaxLight = Math::Max(Points[i],MaxLight); } AABox box(MinLight,MaxLight); I don't think this is the right way to do it. The near plain probably has to extend into the direction of the light source to include potentional shadow casters. I've read the Microsoft article about cascaded shadow maps http://msdn.microsoft.com/en-us/library/windows/desktop/ee416307%28v=vs.85%29.aspx which also includes some sample code. But they seem to use the scenes AABB to determine the near and far plane which I can't since i cant access this information from the funtion I'm working in. Could you guys please link some example code which shows the calculation of such frustum? Thanks in advance! Additional questio: is there a way to construct a WorldToFrustum matrix that represents the above transformation?

  • 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?

  • Brightness Crash and Fan issues in 12.04.1

    - by S.A. McIntosh
    I would just like to state beforehand that I am a total novice in using Ubuntu when it comes to the more complex issues. So I thought it would be best to finally come here and ask for help before being re-directed or closed out for a solution. I have already looked high and low on this board for one but nothing came up for my particular case, so I might as well take a shot asking for the first time here. This is what I have at the moment: -Dell Insprion 1764 w/ 64-bit Intel i5 Core -Dual Boot: Windows 7/Ubuntu 12.04.1 32-bit (from 12.04 install) -Unity shell -Linux kernel: 3.2.0-32 generic-pae ...and this is my fglrxinfo: OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: ATI Mobility Radeon HD 5000 Series OpenGL version string: 4.2.11627 Compatibility Profile Context The one issue I have with using Ubuntu is brightness. With the driver in every time I use the slider in the brightness and lock settings or use the keyboard function, it freezes, goes black and comes up with a scrambled colors page like this in the video. So I have looked all over this board and the web for answers looking for a solution that might have an answer. This is what I have done so far to fix this: -First Solution: Looking around, I found this small fix using terminal: sudo gedit /etc/rc.local followed by adding this into "rc.local" echo # > /sys/class/backlight/acpi_video0/brightness This works rarely with the graphics driver still in and I often get lucky say during restart but reboot would only snap back the brightness at max. -Second Solution Simply remove the graphics driver while leaving the solution of first behind. This solves the issue but results in having the monitor flicker and flash at startup which in itself is not a problem to me but maybe not so good for monitor health. Also it causes the fan to speed up throughout the session and render any program that needs the driver useless. -Third Solution This is the most obvious. Just simply use the brightness on AMD Catalyst Control Center software that came with the driver, and I can say that it's form of brightness is HORRIBLE compared to the actual settings. Which leads up to where I am now, back to the driver to stop the fan speed-up and seems that the only solution to the brightness crash is to use the keyboard-controlled brightness at the login screen NOT the desktop if I want the issued effect but will just snap at max bright again if I restart. Fan speed problem is dealt with but now run the risk of crashing my computer if I so much touch the brightness settings. Speaking of which I found this on launchpad and it seems that the issue has been going far since June of 2012. Any help, redirect link or reference would be greatly appreciated. Thank you.

  • "Well, Swing took a bit of a beating this week..."

    - by Geertjan
    One unique aspect of the NetBeans community presence at JavaOne 2012 was its usage of large panels to highlight and discuss various aspects (e.g., Java EE, JavaFX, etc) of NetBeans IDE usage and tools. For example, here's a pic of one of the panels, taken by Markus Eisele: Above you see me, Sean Comerford from ESPN.com, Gerrick Bivins from Halliburton, Angelo D'Agnano and Ioannis Kostaras from the NATO Programming Center, and Çagatay Çivici from PrimeFaces. (And Tinu Awopetu was also on the panel but not in the picture!) On one of those panels a remark was made which has kind of stuck with me. Henry Arousell, a member of the "NetBeans Platform Discussion Panel", who works on accounting software in Sweden, together with Thomas Boqvist, who was also at JavaOne, said, a bit despondently, I thought, the following words at the start of the demo of his very professional looking accounting software: "Well, Swing took a bit of a beating this week..." That remark comes in the light of several JavaFX sessions held at JavaOne, together with many sessions from the web and mobile worlds making the argument that the browser, tablet, and mobile platforms are the future of all applications everywhere. However, then I had another look at the list of Duke's Choice Award winners: http://www.oracle.com/us/corporate/press/1854931 OK, there are 10 winners of the Duke's Choice Award this year. Three of them (JDuchess, London Java Community, Student Nokia Developer Group) are not awards for software, but for people or groups. So, that leaves seven awards. Three of them (Hadoop, Jelastic, and Parleys) are, in one way or another, some kind of web-oriented solution, though both Hadoop and Jelastic are broader than that, but are service-oriented solutions, relating to cloud technologies. That leaves four others: NATO air defense software, Liquid Robotics software, AgroSense software, and UNHCR Refugee Registration software. All these are, on the software level, Java desktop solutions that, on the UI layer, make use of Java Swing, together with LuciadMaps (NATO), GeoToolkit (AgroSense), and WorldWind (Liquid Robotics). (And, it went even further than that, i.e., this is not passive usage of Swing but active and motivated: Timon Veenstra, during his AgroSense demo, said "There are far more Swing applications out there than we seem to think. Web developers just make more noise." And, during his Liquid Robotics demo, James Gosling said: "Not everything can be done in HTML.") Seems to me that Java Swing was the enabler of more Duke's Choice Award winners this year than any other UI-oriented Java technology. Now, I'm not going to interpret that one way or another, since I've noticed that interpretations of facts tend to validate some underlying agenda. Take any fact anywhere and you can interpret it to prove whatever opinion you're already holding to be true. Therefore, no interpretation from me. Simply stating the fact that Swing, far from taking a beating during JavaOne 2012, was a more significant user interface enabler of Duke's Choice Award winners than any other Java user interface technology. That's not an interpretation, but a fact.

  • Repository and Ticket management in a Windows Environment

    - by saifkhan
    I’ve been using AxoSoft’s bug tracking application for a while, although and excellent piece of software I had some issues with it ·         It was SLOOOW (both desktop and web). I don’t care what Axosoft says, I tired multiple servers etc. I’ve been long enough in this field to tell you when something is not right with an app. ·         The cost! It’s not feasible for a small team.   I must say though, that they have some nice features which are not commonly found on other bug tracking software. I wouldn’t go on to list any here. I would prefer you download and try their app and see for yourself. In my quest to find a replacement, I tried a few. The successor had to satisfy the following ·         A 99.99% Windows Environment. ·         Bug Tracking. ·         Ticket Management (power users and project managers can open tickets on projects). ·         Repository (I decided to merge bug tracking and repository to get my team to be more productive). ·         Unlimited users. ·         Cost. Being the head of IT security for the firm I work for, making the decision to move data offsite was a hard decision to make, but turned out to be one I am not regretting so far. My choice was down to Altassian JIRA and codebaseHQ. I ended up going with the latter… (I still love the greenhopper from Altassian…its freaking cool!) CodebaseHQ is nice and simple and has all the features I needed. I’ve been using them for a few months now and very happy. Their pricing…well, see for yourself. I was also able to get our SVN data… (Yes, SVN! I don’t go near the Visual Sourcesafe thing…it’s not that safe (pardon the pun). I am hearing some nice things about TFS 2010) over to codebaseHQ. We use VisualSVN to access repositories. …so if you are a Windows developer (or team) codebaseHQ is worth checking out!

  • Access forbidden 403 error in xampp

    - by Ramvignesh
    I am very new to xampp. I have made a fresh xampp install with the following commands. sudo su cd /tmp wget bit.ly/1cmyrUo -O xampp-32bit.run chmod 777 ./xampp-32bit.run sudo ./xampp-32bit.run Then I made a perl file to check whether my xampp works. The following is my sample.pl file content. #!usr/bin/perl print "content-type:text/html\n"; print(header()); use CGI qw(:standard); print(start_html()); print "Hello. I am ram"; print(end_html()); After copying my perl file from /home/vicky/desktop to /opt/lampp/cgi-bin. I started my xampp with the following command. /opt/lampp/lampp start Then I ran my sample.pl in the localhost with the help of the http://localhost/cgi-bin/sample.pl in my mozilla browser. I just got the following window. I found only answers relating to the 'new security concept error' and 'accessing virtual host issue'. I did came across an askubuntu query, a bid similar to that of mine. It had no answers but some comments. One comment suggested to change the file permissions. It directed to get help from here. It said to change the directory permission as 755 and file permission as 644 to resolve this kind of issue. When I tried to do that, I came to know that my cgi-bin directory already had 755 permission and my sample.pl had 644 permission. I have no solutions now.

  • Why learn Flash Builder 4 (Flex) when I can just use Flash Professional?

    - by Jason McKenna
    I want to learn Flash Builder 4 (Flex) because I see so many jobs requesting experience with it. I also just like knowing stuff. I am also very interested in focusing on RIA development now. BUT... can anyone tell me CLEARLY why the heck I would ever use FLEX over Flash Pro? It is a time investment, so is it worth it? All I read are misguided posts about how Flash Pro is for games and banner ads, and Flex is for programmers and RIAs blah blah... this simply isn't so from my 9 years of contracting experience. I'm 99.9% certain that I can build anything a flex developer can build, but using Flash Pro. I can build powerful AS3-driven apps for the desktop, mobile device, or browser, and I can link to databases with XML and I can import text files and communicate with ColdFusion and everything. The advantage with Flash Pro is that I can also easily and clearly animate transitions and build custom elements that look the way I want/need them to look for my specific client. Why would I want to use a bunch of pre-built components that drive my file sizes to the moon? Who is happy with a drag-n-drop button? Is Flex just a thing made for programmer people with no artistic inclination? What is the advantage of using it? It takes me back to Visual Basic class. Seems like a pain to have to use multiple tools to import crap from Flash Pro into Flex and yada yada... why when I can do it all nicely in Flash Pro to begin with. Am I clueless, or missing some major piece of the puzzle? Thanks for any clarity. PS, I couldn't care less about the code editors. It ain't that bad people. They make it out like the thing doesn't even respond to keyboard input or something. Does everything I need it do anyways. Please help out here. If I just don't need to learn it, I don't want to waste the time.

  • StreamInsight 1.0 Released

    - by Roman Schindlauer
    One piece in the set of products offered in SQL Server 2008 R2 that has generated a lot of buzz and interest during its CTP phase is StreamInsight, Microsoft’s platform for Complex Event Processing. Microsoft’s information platform vision provides enterprises with a “complete approach” to managing information assets, enabling all businesses to gain strategic value from information from the desktop to the datacenter to the cloud. And StreamInsight V1 is one essential piece in this spectrum. After more than a year of blood, sweat, tears, and insane amounts of coffee we are proud to release the first version of our Complex Event Processing Framework.   Those of you who have been following our Community Technology Previews (CTPs) throughout last year have already had the possibility to familiarize themselves with the product. Early feedback was not only incredibly positive, but also very constructive and strongly influenced the final feature set. Four notable increments over our last public CTP are: Count windows Non-occurrence detection (Anti-Join) Dynamic query composition at runtime Synchronize time across input streams Additionally, many smaller issues and bugs were addressed. A few APIs slightly changed with respect to the November CTP, but porting your application to RTM should not require a lot of effort.   Here are the (english) bits - choosing the evaluation license during setup lets you already play with this version. Before you install, make sure to uninstall any previous CTP version:   StreamInsight X86StreamInsight X64   Within a few days, we will update our product page and add download links and instructions there as well.   The StreamInsight documentation is provided through a help file as part of the installation as well as through Books Online on MSDN. We also invite you to visit the StreamInsight Blog and the StreamInsight Forum, which is a great place to discuss questions and issues with the community and the development team.   Regards,Roman Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • How to force a new Notification in notify-osd to show up without waiting for the earlier one to exit?

    - by Nirmik
    I have made a script(and a .desktop shortcut leading to this script) for starting and stoping xampp... It checks the status of xampp and accordingly either starts or stops xampp. Now i have assigned a notification as soon as the script is started to display "Starting xampp..." or "Stopping xampp..." and then when xampp is started or stopped,it displays "Xampp started..." or "Xampp stopped..." I've used notify-send to show notification as seen in the script below Now the thing is that here,the second notification waits for the 1st one to disappear and then pops up even if xampp has started/stopped. I want the new notification to appear immediately by forcing the earlier one to exit before the completion of its life-cycle. This can be seen to take plce when you activate/deactivate wireless/networking immediately... For example the "Wireless enabled" comes up on selecting enable wireless and if you immediately select disable wireless,the "Wireless disabled" notification comes up without waiting for "Wireless enabled" notification to complete its life-cycle. So how do i achieve this? #!/bin/sh SERVICE='proftpd' if ps ax | grep -v grep | grep $SERVICE /dev/null then notify-send -i /opt/lampp/htdocs/xampp/img/logo-small.gif "Stopping XAMPP..." && gksudo /opt/lampp/lampp stop && notify-send -i /opt/lampp/htdocs/xampp/img/logo- small.gif "XAMPP Stoped." else notify-send -i /opt/lampp/htdocs/xampp/img/logo-small.gif "Starting XAMPP..." && gksudo /opt/lampp/lampp start && notify-send -i /opt/lampp/htdocs/xampp/img/logo-small.gif "XAMPP Started." fi On the man page for notify-send I found --urgency=LEVEL or -u where levels are low, normal, critical. Is this of any use? making it critical? Also I tried it with the command- notify-send -u=critical"Testing" but that dint work...it gives the error- Unknown urgency criticalTesting specified. Known urgency levels: low, normal, critical. or if I give the command notify-send -u=LOW"Testing" it gives me error missing argument to -u Any relation??

  • How do I reconfigure my GLES frame buffer after a rotation?

    - by Panda Pajama
    I am implementing interface rotation for my GLES based game for iOS, written in Xamarin.iOS with OpenTK. I am detecting the rotation by overriding WillRotate, in my UIViewController, and I correctly re-setup all of my projection matrices. However, when drawing a sprite, the image looks a bit blurrier on the landscape version compared to the portrait version, as you can see in the following closeups magnified 10x. Portrait (before rotating) Landscape (after rotating) In both cases, I'm using the same texture with the same sampler, the same shader, and the same GL state. I just changed the order of the parameters in the projection matrix, so the resulting sizes should be exactly the same pixelwise. Since this could be thought of as a window resize, I suppose that the framebuffer has to be recreated to the new size. When working on desktop apps on Direct3D11 (SharpDX), I would have to call swapChain.ResizeBuffers() to do this. I have tried setting AutoResize = true in my iPhoneOSGameView, but then the framebuffer gets clipped as I rotate the interface, and then everything disappears when rotating the interface again. I'm not doing anything strange, my framebuffer initialization is pretty vanilla: int scaling = (int)UIScreen.MainScreen.Scale; DeviceWidth = (int)UIScreen.MainScreen.Bounds.Width * scaling; DeviceHeight = (int)UIScreen.MainScreen.Bounds.Height * scaling; Size = new System.Drawing.Size((int)(DeviceWidth), (int)(DeviceHeight)); Bounds = new System.Drawing.RectangleF(0, 0, DeviceWidth, DeviceHeight); Frame = new System.Drawing.RectangleF(0, 0, DeviceWidth, DeviceHeight); ContextRenderingApi = EAGLRenderingAPI.OpenGLES2; AutoResize = true; LayerRetainsBacking = true; LayerColorFormat = EAGLColorFormat.RGBA8; I get inconsistent results when changing Size, Bounds and Frame on my CreateFrameBuffer override, but since the documentation is so incomplete (it has nothing on Bounds and Frame), I have resorted to randomly changing stuff here and there without really knowing what is going on. There is a similar question which has no answers. However, I don't know if they're experiencing the same problem as I am. Is my supposition that recreating the framebuffer is necessary, correct? If so, does anybody know how to do it correctly in OpenTK for Xamarin.iOS?
