  - by Tori Wieldt

  On December 11, 2012 Oracle released Java SE 7 Update 10 (Java SE 7u10). This release includes enhanced security features and support for new platforms. Enhanced Security Features The JDK 7u10 release includes the following security enhancements: The ability to disable any Java application from running in the browser. This mode can be set in the Java Control Panel or (on Microsoft Windows platform only) using a command-line install argument. The ability to select the desired level of security for unsigned applets, Java Web Start applications, and embedded JavaFX applications that run in a browser. Four levels of security are supported. This feature can be set in the Java Control Panel or (on Microsoft Windows platform only) using a command-line install argument. New dialogs to warn you when the JRE is insecure (either expired or below the security baseline) and needs to be updated.

• Camera field of view: 3D projections & trigonometry

  - by Thomas O

  Okay, here goes. I have a camera at (Xc, Yc, Zc.) The Xc and Yc coordinates are latitude/longitude, and the Zc coordinate is an altitude in metres. I have a point at (Xp, Yp, Zp) and a field of view on the camera (Th1, Th2) - where Th1 is horizontal FOV and Th2 is vertical FOV. Given this information, I'd like to: test if the point is visible (i.e. in the camera's FOV) project the point as the camera would see it I've figured out already that the camera's horizontal view at any given distance is tan(Th1) * distance, but I don't know how to test if the point is visible. Accuracy is not critical. I would prefer a simple solution over a complicated solution, if it works well enough. The computations will be performed by a small microcontroller, which isn't very fast at things like trig functions. P.S. this is not homework, I'm doing this for some game development. It will be integrated with the real world, hence the latitude/longitude/altitude. It involves flying real RC planes through virtual hoops (or chasing virtual targets), so I have to project the positions of these hoops on a display.

• Apple Co-founder Wozniak: Windows Phone is more beautiful and intuitive than Android

  - by Gopinath

  It’s a great day for Microsoft and Nokia who are working hard to resurrect Windows Phone. Steve Wozniak, the co-founder of Apple and gadget lover, has all praise for Windows Phone after using Nokia Lumia 900 for a while. He shared his experience of using Lumia powered by Windows Phone 7.5 in a interview and he is very impressed. Here are the few good quotes from the interview Just for looks and beauty, I definitely favor the Windows 7 Phone over Android. I’m kinda shocked how every screen is much more beautiful than the same apps on Android and iPhone. I’m just shocked, I haven’t seen anything yet that isn’t more beautiful than the other platforms. It’s more intuitive and beautiful. This is going to change the perception of Windows Phone  which is seen  as “not-so good” operating system for mobiles.  Along with these high profile endorsements, if Microsoft can manage to attract developers in building good apps then Windows Phone is going to be a fitting competitor to iOS and Android. via aNewDomain

• Inserting HTML code with jquery

  - by J. Robertson

  One of our web applications is a page that takes in a serial number and various information is returned and displayed to the user. The serial is passed via AJAX, and based on the response, one of the following can happen - An error message is shown A new form replaces the previous form Now, the way I am handling this is to use jQuery to destroy (using $.remove()) the table that displayed the initial serial form, then I'm appending another html table that contains another form. Right now I am including that additional form as part of the html source, and just setting it to display:none, then using jQuery to show it when appropriate. However, I don't like this approach because if someone views source on the page, they can see that table html code that is not being displayed. My next thought would be to use AJAX to read in another HTML file, and append it that way. However, I am trying to keep down the number of files this project uses, and since most pages in our project will use AJAX, I could see a case where there are multiple files containing HTML snippets - and that feels sloppy to me. What is the best way to handle a case where multiple html elements are being shown and removed with jQuery?

• Free Team Foundation Service a Boon for Play Projects

  - by Ken Cox [MVP]

  My ‘jump in and sink or swim’ learning style leads me to create dozens of unbillable ‘play’ projects in Visual Studio 2012.  For example, I’m currently learning to customize the powerful auction/fixed price/classifieds software called AuctionWorx Enterprise.  I make stupid mistakes as I grasp a new API and configure projects. It’s frustrating to go down a rat hole and discover the VS IDE’s Undo doesn’t reach back to a working build from the previous weekend. Enter Visual Studio’s Free Team Foundation Service.  Put your play projects into the free source control and check in (or shelve) a snapshot before embarking on something risky. (I already use Discount ASP.NET’s Team Foundation Server hosting for client projects so there’s zero TFS/VS learning curve for me and first class GUI support.) TFS is free right now for teams of five or fewer. I’m not naive enough to expect ‘free’ to last forever. So, it’ll be interesting to see how much Microsoft intends to charge in 2013 for TFS. In the meantime, why not grab some free source code storage? BTW, it’s weird to realize that Microsoft is backing up my junky little playtime code on three physically-distinct servers every day - and taking incremental backups every hour.

• Google Loon–A network of balloons to provide internet to everyone

  - by Gopinath

  Google once just a super powerful search engine provider and now they are venturing in to a lot of interesting non software projects like self driving cars, glasses that beam information right on to your eye balls, high speed internet services @ 1 Giga bytes per second. A recent addition to this innovative list is Google Loon – a network of flying balloons that provide internet access to remote parts of the world where it is not feasible for many governments/corporate to provider internet services. Google says there are several billions of people around the world who don’t have access to internet and Google Loon aim is to provide internet facilities to all these people. A pilot project is started couple of days ago by launching 30 balloons into stratosphere from New Zealand. These balloons fly 20 Kilometers above earth(much higher than where aero planes fly) and they beam internet to homes having Loon receiver wirelessly. Checkout the embedded introductory video on Google Loon What is in it for Google? Why is Google getting into these type of projects and what is in it for them? Google is the gateway to web and majority of people find information on web using Google Services/Software. So providing internet facilities to more people means, more people using Google services and it in turn contributes to their revenue growth. Google is not a charity, they do all these projects to earn money just like every other corporate. The best part is while earning money they are touching lives of billions of people in a positive way. Just imagine everyone in the world connected and have ability to take informed decisions irrespective of whether they live in developed countries or underprivileged parts of the world! Wow that will be a beautiful day.

• Transport rules on a live@edu instance to filter SSNs

  - by wbfreema

  Has anyone implemented transport rules on a live@edu(or whatever Microsoft is calling it these days) instance to reject the delivery of messages that include SSN's? I see how to set up transport rules in Exchange 2007, and even how to do it in the Windows Live Admin page, though the rules there don't seem to allow for regexes, can anyone confirm this? If this is the case has anyone ever connected Powershell to a live@edu instance to implement the code found at the bottom of this page: http://technet.microsoft.com/en-us/library/aa997187.aspx What I really need is a concise how-to.

• Memory concerns while plotting escape from DLL Hell in Delphi

  - by Peter Turner

  I work on a program with about 50 DLLs that are loaded from one executable, it's an old organically grown program where the only rationale for creating a new DLL is that one previously didn't exist to fill a given need. (and namespaces didn't exist in Delphi so it never crossed our mind to make dll1.main.pas, dll2.main.pas or something even more unique) What we want to do is consolidate all these DLLs into one executable, since none of them are used out of the program, there shouldn't be much of a problem. The concern my boss has is that if we did this, the memory overhead for terminal server clients would go through the roof. So, I've stepped through enough initialization code to know that lots of stuff is done every time a DLL is loaded in to memory, but say I've got a project with about 4000 files, and 50 dlls, 10 of which are probably utilized by any one user in any one session of the program. The 50 dlls are about 2/3rds form files, if not more, but beyond that there's not a lot of other resources being loaded (only a few embedded pictures, icons, cursors, etc..). If I loaded all these files in to memory, how much memory is used per unit? how much is used per class? How do I keep the overhead down? and what is the biggest project one can reasonably expect to build with Delphi? This tidbit won't help answering, but I think it might clarify what my boss is worried about, we currently start our program at about 18megs, normal working conditions are usually less than 40 megs, he thinks it could climb as high as 120 megs.

• How can I convert audio files to this format?

  - by jeffamaphone

  I have a bunch of audio files that are named .wav but it seems not all .wavs are created equal. For example: $ file * file1.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz file2.wav: Audio file with ID3 version 2.2.0, contains: MPEG ADTS, layer III, v1, 160 kbps, 44.1 kHz, JntStereo file3.wav: Claris clip art? file4.wav: Audio file with ID3 version 2.2.0, contains: MPEG ADTS, layer III, v1, 160 kbps, 44.1 kHz, JntStereo And for good measure, a non-wav: file5.m4a: ISO Media, MPEG v4 system, iTunes AAC-LC I would like to convert all of these files to the format that file1.wav is: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz What is the proper set of arguments to pass to afconvert to make that happen?

• How do I prevent missing network from slowing down boot-up?

• If You Include the Groovy Editor...

  - by Geertjan

  ...in a NetBeans RCP application, what additional JARs will you need to include for the Groovy Editor to work? Leaving aside the debate on the current state & quality of the NetBeans Groovy Editor, so, assuming you need the Groovy support that the NetBeans Groovy Editor provides, you would check the Groovy Editor checkbox in the Project Properties dialog of your application: As you can see, however, the Groovy Editor depends on other modules, some of which, in turn, depend on yet other modules, and so on. So, I clicked the "Resolve" button above and then created a ZIP distribution, to see which additional JARs had been included. Until that point, I had only been using the "platform" cluster, which means that absolutely everything found in the ZIP's "ide" cluster and "java" cluster have only been included so that the Groovy Editor could be included, i.e., all thanks to clicking the "Resolve" button above. Let's first look at what that means for the "java" cluster: That's not so bad and kind of a side effect of Groovy being Java, i.e., a lot of Java functionality is needed. Now let's look at the "ide" cluster: So, in answer to the original question, if all you want in your NetBeans Platform application, in terms of editor functionality, is the Groovy Editor, then you have a pretty high price to pay. At the very least, I would have assumed that the project support JARs and the debugger support JARs would not be so tightly coupled with the Groovy Editor. That would be a cool thing to separate out from the editor support.

• Does removing admin rights really mitigate 90% of Critical Windows 7 vulnerabilities found to date?

  - by Jordan Weinstein

  Beyondtrust.com published a report, somewhat recently, claiming among other quite compelling things, "90% of Critical Microsoft Windows 7 Vulnerabilities are Mitigated by Eliminating Admin Rights" Other interesting 'facts' they provide say that these are also mitigated by NOT running as a local admin: 100% of Microsoft Office vulnerabilities reported in 2009 94% of Internet Explorer and 100% of IE 8 vulnerabilities reported in 2009 BUT, reading the first page or so of the report I saw this line: A vulnerability is considered mitigated by removing administrator rights if the following sentence is located in the Security Bulletin’s Mitigating Factors section, ?Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. could be sounds pretty weak to me so and I wondered how valid all this really is. I'm NOT trying to say it's not safer to run without admin rights, I think that is well known. I just wonder if these stats are something you would use as ammo in an argument, or use to sell a change like that (removing users as local admins) to business side? Thoughts?

• .NET development on Macs

  - by Jeff

  I posted the “exciting” conclusion of my laptop trade-ins and issues on my personal blog. The links, in chronological order, are posted below. While those posts have all of the details about performance and software used, I wanted to comment on why I like using Macs in the first place. It started in 2006 when Apple released the first Intel-based Mac. As someone with a professional video past, I had been using Macs on and off since college (1995 graduate), so I was never terribly religious about any particular platform. I’m still not, but until recently, it was staggering how crappy PC’s were. They were all plastic, disposable, commodity crap. I could never justify buying a PowerBook because I was a Microsoft stack guy. When Apple went Intel, they removed that barrier. They also didn’t screw around with selling to the low end (though the plastic MacBooks bordered on that), so even the base machines were pretty well equipped. Every Mac I’ve had, I’ve used for three years. Other than that first one, I’ve also sold each one, for quite a bit of money. Things have changed quite a bit, mostly within the last year. I’m actually relieved, because Apple needs competition at the high end. Other manufacturers are finally understanding the importance of industrial design. For me, I’ll stick with Macs for now, because I’m invested in OS X apps like Aperture and the Mac versions of Adobe products. As a Microsoft developer, it doesn’t even matter though… with Parallels, I Cmd-Tab and I’m in Windows. So after three and a half years with a wonderful 17” MBP and upgraded SSD, it was time to get something lighter and smaller (traveling light is critical with a toddler), and I eventually ended up with a 13” MacBook Air, with the i7 and 8 gig upgrades, and I love it. At home I “dock” it to a Thunderbolt Display.

• The one feature that would make me invest in SSIS 2012

  - by Peter Larsson

  This week I was invited my Microsoft to give two presentations in Slovenia. My presentations went well and I had good energy and the audience was interacting with me. When I had some time over from networking and partying, I attended a few other presentations. At least the ones who where held in English. One of these was "SQL Server Integration Services 2012 - All the News, and More", given by Davide Mauri, a fellow co-worker from SolidQ. We started to talk and soon came into the details of the new things in SSIS 2012. All of the official things Davide talked about are good stuff, but for me, the best thing is one he didn't cover in his presentation. In earlier versions of SSIS than 2012, it is possible to have a stored procedure to act as a data source, as long as it doesn't have a temp table in it. In that case, you will get an error message from SSIS that "Metadata could not be found". This is still true with SSIS 2012, so the thing I am talking about is not really a SSIS feature, it's a SQL Server 2012 feature. And this is the EXECUTE WITH RESULTSETS feature! With this, you can have a stored procedure with a temp table to deliver the resultset to SSIS, if you execute the stored procedure from SSIS and add the "WITH RESULTSETS" option. If you do this, SSIS is able to take the metadata from the code you write in SSIS and not from the stored procedure! And it's very fast too. Let's say you have a stored procedure in earlier versions and when referencing that stored procedure in SSIS forced SSIS to call the stored procedure (which can take hours), to retrieve the metadata. Now, with RESULTSETS, SSIS 2012 can continue in milliseconds! This is because you provide the metadata in the RESULTSETS clause, and if the data from the stored procedure doesn't match this RESULTSETS, you will get an error anyway, so it makes sense Microsoft has provided this optimization for us.

• Best approach for utility class library using Visual Studio

  - by gregsdennis

  I have a collection of classes that I commonly (but not always) use when developing WPF applications. The trouble I have is that if I want to use only a subset of the classes, I have three options: Distribute the entire DLL. While this approach makes code maintenance easier, it does require distributing a large DLL for minimal code functionality. Copy the classes I need to the current application. This approach solves the problem of not distributing unused code, but completely eliminates code maintenance. Maintain each class/feature in a separate project. This solves both problems from above, but then I have dramatically increased the number of files that need to be distributed, and it bloats my VS solution with tiny projects. Ideally, I'd like a combination of 1 & 3: A single project that contains all of my utility classes but builds to a DLL containing only the classes that are used in the current application. Are there any other common approaches that I haven't considered? Is there any way to do what I want? Thank you.

• JPEG images not loading on PlayBook (Marmalade + iwgame)

  - by Vexille

  I'm using iwgame on a test project and I was trying to render different resolutions of JPG and PNG images. Everything works fine on the Marmalade Simulator, however once I deploy the game to our PlayBook and run it, only the PNG images are shown. I have declared the images in the MKB file and on a XML file iwgame's using to load the images. I've checked the deployments folder and all images are present in the intermediatefiles/native folder. We're currently using a BlackBerry only license, so we can only test this on the PlayBook, but we do intend to get a Community license and deploy to iOS and Android devices eventually (I'm not sure if this is a problem exclusive to the PlayBook). I really don't know if this is a Marmalade or a iwgame issue. I have a different test project without iwgame and it simply won't run with jpg images (I get the error: 'Could not find handler for extension "jpg"'). While searching for a sollution, I've seen people talking about using libjpg, but I've also found that Marmalade supposedly has integrated native jpeg support (and because of that iwgame has abandoned their jpeg loading support since v0.340), so I don't know what to think. I'm currently using the most recent versions of both Marmalade and iwgame, I believe: Marmalade 6.1.2 and iwgame 0.400. Also, please let me know if there's an easier or better way to do this, such as linking libjpg or something (I'm not exactly sure how to do this). I really would appreciate some help with this, there's a huge difference in size for the images we're planning to use, from a ~500kb jpg file to a ~3.5mb png file. Thanks, guys.

• redmine repository management

  - by Alex

  We are trying to setup a redmine installation for our group which should work with both SVN and Git repos. Since we want to keep the repos on the server and avoid the whole privileges and hosting mess (root access, local repos, ...), we want configure redmine to manage repo creation and destruction by itself. In short, redmine should create a repository automatically for a new project and delete it if the project is deleted, with no extra setup steps from our admin. So far I found reposman for SVN and redmine_git_hosting for Git, but I am unsure if match our requirements. Are these the tools we are looking for or is there any other alternative? Thank you

• How do I uninstall Office Live Add-in 1.4 after installing Office 2010?

  - by Shevek

  Last night I upgraded to Office 2010 RTM from MSDN. I'm now trying to uninstall the Office Live Add-in that I used with Office 2007 as this functionality is built in to Office 2010. When I run the uninstall from control panel I get the following message: Microsoft Office Live Add-in cannot be installed because you do not have the right version of Microsoft Office installed on your computer Google has pointed to 2 solutions, both of which are pretty useless: Use the MS Windows Installer Cleanup - this is not good because all it does is remove the Installer entry from the registry, leaving all the installed files behind Uninstall Office 2010, uninstall Add-in, reinstall Office 2010 - that is just ridiculous, but typical MS response So, can I get this off my system without resorting to option 2?

• how do I write a functional spec quickly and efficiently

  - by giddy

  So I just read some fabulous articles by Joel on specs here. (Was written in 2000!!) I read all 4 parts, but Im looking for some methodical approaches to writing my specs. Im the only lonely dev, working on this fairly complicated app (or family of apps) for a very well known finance company. I've never made something this serious, I started out writing something like a bad spec, an overview of some sorts, and it has wasted a LOT of my time. Ive also made 3 mockup-kinda-thingies for my client so I have a good understanding of what they want. Also released a preview (a throw away working app with the most basic workflow), and Ive only written and tested some of the very core/base systems. I think the mistake Ive been making so far is not writing a detailed spec, so Im getting to it now. So the whole thing comprises of An MVC website (for admins & data viewing) 2 Silverlight modules (For 2 specific tasks) 1 Desktop Application Im totally short on time, resources and need to get this done quick, also, need to make sure these guys read it up equally quick and painlessly. So how do I go about it, Im looking for any tips, any real world stuff, how do you guys usually do it? Do you make a mock screenie of every dialog/form/page? Im thinking of making a dummy asp.net web forms project, then filling in html files in folders and making it look like my mvc url structure. Then having a section in the spec for the website and write up a page for every URL Ive got with a screenie. For my win forms app, Ive made somewhat of a demo Win Form project, would I then put in a dialog or stucture everything as I would in the real app and then screen shot it?

• Code Contracts and Pex at MSDN Live 2010

  - by terje

  One of the 6 sessions I and Mikael Nitell is running on MSDN Live 2010 here in Norway is about Code Quality, and part of that session goes through the use of Code Contracts and Pex.  Both fantastic tools ! They can be used togethers, but are also completely independent from each other, and can be used as a single Code Contracts  has to downloaded separately from VS 2010 (works also on VS 2008).   Start looking at http://msdn.microsoft.com/en-us/devlabs/dd491992.aspx . This download is a free download.   Code Contracts originates form the ideas of Bertrand Meyer – Design by Contract, take a look here. Pex is found on the MSDN Subscription download, so it requires an active MSDN Subscription. Start to get it from here http://research.microsoft.com/en-us/projects/pex/downloads.aspx .  The current version as of 14.4.10 is 0.9, which works with the 2010 RC.  A new version is due this week.  Pex is a tool to generate unit tests, and does this very intelligently.  Perfect to make tests for legacy code, but also to make sure you get all paths tested.  See the Reference information and project startup information.

• Standards for how developers work on their own workstations

  - by Jon Hopkins

  We've just come across one of those situations which occasionally comes up when a developer goes off sick for a few days mid-project. There were a few questions about whether he'd committed the latest version of his code or whether there was something more recent on his local machine we should be looking at, and we had a delivery to a customer pending so we couldn't wait for him to return. One of the other developers logged on as him to see and found a mess of workspaces, many seemingly of the same projects, with timestamps that made it unclear which one was "current" (he was prototyping some bits on versions of the project other than his "core" one). Obviously this is a pain in the neck, however the alternative (which would seem to be strict standards for how each developer works on their own machine to ensure that any other developer can pick things up with a minimum of effort) is likely to break many developers personal work flows and lead to inefficiency on an individual level. I'm not talking about standards for checked-in code, or even general development standards, I'm talking about how a developer works locally, a domain generally considered (in my experience) to be almost entirely under the developers own control. So how do you handle situations like this? Are the one of those things that just happens and you have to deal with, the price you pay for developers being allowed to work in the way that best suits them? Or do you ask developers to adhere to standards in this area - use of specific directories, naming standards, notes on a wiki or whatever? And if so what do your standards cover, how strict are they, how do you police them and so on? Or is there another solution I'm missing? [Assume for the sake of argument that the developer can not be contacted to talk through what he was doing here - even if he could knowing and describing which workspace is which from memory isn't going to be simple and flawless and sometimes people genuinely can't be contacted and I'd like a solution which covers all eventualities.]

• A website to compare software/hardware/electronics?

  - by liori

  Hello, When choosing software or hardware I often Wikipedia's comparision pages like the page on Comparison of project management software. However, criteria on including items on such lists are sometimes unclear (f.e. project has to be "notable", has to have a Wikipedia page), and the number of compared features are limited. Also, Wikipedia's software doesn't make it easy to edit such lists. I am looking for an external webapp/website that would do the task of comparing different solutions in the world of software, hardware, maybe even electronics, in this kind of social way. Is there any kind of such service? It should allow users to add new entries, add new features to compare and discuss items in a collaborative way. It should be also easy to browse already entered items, filter by features. (this might be a good idea for a startup ;-))

• Struggling to get set up with JOGL2.0

  - by thecoshman

  I guess that Game Dev' is a more sensible place for my problem then SO. I did have JOGL1.1 set up and working, but I soon discovered that it did not support the latest OpenGL, so I started work on upgrading to JOGL2.0 it's not gone too well. Firstly, is it worth me trying to get JOGL to work, or should I just move over to LWJGL? I am fairly comfortable with OpenGL (via C++) and from what I did get working with JOGL1.1, I seem to be OK adapting to it. Assuming that I stick with JOGL, am I foolish for trying to use JOGL2.0? From what I can gather, JOGL2.0 is still in beta, but I am willing to go with it as I want to make use of the latest OpenGL I can. I have been using the Eclipse IDE and have set up a user library for JOGL, here is a screen shot of the configuration and I have added this user library to my own Eclipse project. the system variable %JOGL_HOME% points to "C:\Users\edacosh\Downloads\JOGL2.0" so that should work fine. Now, the problem I actually having, when I try to run my code, on the line GLProfile glp = GLProfile.getDefault(); The code stops with the following message... Exception in thread "main" java.lang.NoClassDefFoundError: com/jogamp/common/jvm/JVMUtil at javax.media.opengl.GLProfile.<clinit>(GLProfile.java:1145) at DiCE.DiCE.<init>(DiCE.java:33) at App.<init>(App.java:17) at App.main(App.java:12) Caused by: java.lang.ClassNotFoundException: com.jogamp.common.jvm.JVMUtil at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 4 more I have also set my project to ensure that it is using jre6 along with jdk6, as I was having some issues. I hope I have given you enough information to be able to help me. It probably doesn't help that I am rather new to Java, been developing in C++ for ages. Thanks
