• SANS Webcast: Label Based Access Controls in Oracle Database 11g

  - by Troy Kitch

  Controlling access to data subsets within an application table can be difficult and inefficient especially when faced with specific data ownership, consolidation and multi-tenancy requirements. However, this can be elegantly addressed using label based access control (LBAC). In this webcast you will learn how LBAC using Oracle Label Security and Oracle Database 11g can easily enforce row-level access based on user security clearance. In addition, Oracle security experts will discuss real world case studies demonstrating how customers, in industries ranging from retail to government, are relying on Oracle Label Security for virtual information partitioning and secure consolidation of information.  Register for the July 12 webcast now.

• What version of Java should I target for applets?

  - by Christopher Horenstein

  I recently deployed an applet that seems to require Java 6 Update 24. I assume the reason for this requirement is the matching JDK version I used to create the applet (I am new to Java). The fact that my applet requires a Java download/update for users who already have some version of Java installed is a big concern for me; the applets I'm creating slip into a web comic, so it's very disruptive. Having used the most recent version of Java, it seems as though I am able to assume that most of the readers I get will have to update Java to continue reading/playing. Is there a best practice concerning which version of Java to use to make the process of using an applet easy for end-users? Any reading material on this would be very helpful. Should I be using an older version of Java if I don't require new features? I am using Slick for 2D games.

• How to teach computer science ?

  - by proferikson

  I am just starting to teach computer science. It's just the basic level. I'm finding that I sometimes don't know how to approach topics in a way that lets students easily understand. I've found that the best thing is to use analogies. A terrible one, that worked well, was presenting recursion by using the process of eating a burger. (You eat one bite, then you eat the rest). Interesting real world examples do wonders here. I'd like to know the techniques you have used for teaching, or teachers you've had have used that proved particularly effective. I'd also like to know your best analogies and examples for topics in CS101, especially for those harder to grasp topics. I'm teaching the class in Java (as required).

• Geotargeted subfolder questions (Portugal/Brazil and Switzerland)

  - by Lucy

  We are at the beginning of the process to get multilingual versions of a website. We will be using subfolders working off the core domain (eg mydomain.com/fr/), set the geotargeting at webmaster tools and set hreflang attribute. I would really appreciate your help with a couple of questions. 1/Portuguese: we will have a Portuguese language version of the site. Our intention is to use this to cover users in both Portugal AND Brazil. ie, we are not going to do separate folders mydomain.com/pt/ and mydomain.com/br/ Can I use 2 hreflang attributes for this language version to tell Google it covers Brazil AND Portugal? What country code to use for this subfolder? 2/Switzerland Does anyone have best practice advice how to do this? One one hand, the subfolder should be mydomain.com/ch/ but as Switzerland covers 2 language possibilities (French AND German) - what to do? thanks

• TFS: Work Items values from External Databases

  - by javarg

  A common question in TFS forums is how to populate list items from external sources in Work Items. Well, there is not a specific functionality to integrate Work Items with external databases or systems when designing them. Actually, you will need to associate your Work Items fields with Global Lists and then have some automated process update this global list regularly. Download this ImportGlobalList.zip file. I’ve put together a simple class (TfsGlobalList) that you can use to update global list items from a .NET application. You could for example, create a simple Console App and schedule it using Windows Scheduler. This App would query a database and then update a TFS Global List using the provided code. Note: the provided code must be run under an account with modify Global List permissions in TFS. Note: remember to refresh Team Explorer in order to see updates in Work Item field values. Enjoy!

• I can't get ubunutu installation to start

  - by tyler

  AZUS Sabertooth Motherboard, Intel I5 2500 CPU, Windows 7 installed I'm trying to install linux. I first attempted to install pin guy. I burned the ISO; booted from it; got the initial menu; attempting either run the live version from DVD, or install to system; the process stops at a blank screen with the blinking cursor in left corner. So I downloaded Ubuntu and got the same results. Then tried wubi, and ended up in the same position; blinking cursor in left corner.

• How can I unit test a class which requires a web service call?

  - by Chris Cooper

  I'm trying to test a class which calls some Hadoop web services. The code is pretty much of the form: method() { ...use Jersey client to create WebResource... ...make request... ...do something with response... } e.g. there is a create directory method, a create folder method etc. Given that the code is dealing with an external web service that I don't have control over, how can I unit test this? I could try and mock the web service client/responses but that breaks the guideline I've seen a lot recently: "Don't mock objects you don't own". I could set up a dummy web service implementation - would that still constitute a "unit test" or would it then be an integration test? Is it just not possible to unit test at this low a level - how would a TDD practitioner go about this?

• Installation stops at a black screen on a Dell XPS 15z

  - by user780610

  This is my first time trying to install a Linux distro, and I'm having a bit of a time with it. I've tried to install Ubuntu on my new Dell XPS 15z using the Wubi Windows installer (on x64 Windows 7 Pro) and I've also tried mounting the ISO to a USB drive as explained on ubuntu.com. Unfortunately, both methods hit the same problem: after some text stuff, the screen turns off. I still have control over things like keyboard brightness, so it's not that the computer's going idle or anything like that. Any ideas?

• Hard-copy approaches to time tracking

  - by STW

  I have a problem: I suck at tracking time-on-task for specific feature/defects/etc while coding them. I tend to jump between tasks a fair bit (partly due to the inherit juggling required by professional software development, partly due to my personal tendancy to focus on the code itself and not the business process around code). My personal preference is for a hard-copy system. Even with gabillions of pixels of real-estate on-screen I find it terribly distracting to keep a tracking window convienient; either I forget about it or it gets in my ways. So, looking for suggestions on time-tracking. My only requirement is a simple system to track start/stop times per task. I've considered going as far as buying a time-clock and giving each ticket a dedicated time-card. When I start working on it, punch-in; when done working, punch-out.

• file acess slow after deletion of many files

  - by stefan

  I recently accidentally created millions of files in one folder (rougly 5 million) and due to limitations I couldn't process them correctly (maximum argument count exceeded for wc / ls and such stuff). So I deleted them, which took quite a while, but now they're gone. I deleted the files with a regular rm. It weren't any system files. So the files are definitively deleted, but the system is very slow on file stuff now. ls, cat and auto-complete by pressing tab freezes the terminal for several seconds. Is this some sort of fragmentation issue? Is it an issue with the files beeing still somehow present?

• How to do a cacheable redirection?

  - by John Doe

  When users enter my website example.com, their "preferred" language is detected and they are redirected (using a 301 Moved Permanently redirection) to example.com/en/ (for english), example.com/it/ (for italian), etc. It works perfectly, but when I analized my website with the Google Page Speed tool it gave me the following advice. Many pages, especially mobile pages, redirect users to a different URL, for instance from www.example.com to m.example.com. Making this redirect cacheable by the user's browser can speed up page load times for repeat visitors to a site. And later it says We recommend using a 302 redirect with a cache lifetime of one day. The redirect should include a Vary: User-Agent header as well as a Cache-Control: private header. So my questions are, how can I do a "cacheable" redirection in PHP? Would the following be enough? header("HTTP/1.0 302 Moved Temporarily"); header("Location: example.com/whatever"); exit;

• Webinar Recording on Cross Platform Development with MonoTouch and Mono for Android

  - by Wallym

  The iPhone and Android are dominant in the marketplace. The two platforms currently have 85% of the smartphone marketplace and are continuing to grow that marketshare. Developers are being tasked with targeting these two platforms. In this session, we’ll take a high level look at how we can use c# and .NET knowledge to share code between iOS and and Android. We’ll look at linked files, using the Xamarin Mobile API, the challenges of running across platforms and frameworks, as well as other features of Visual Studio, Monotouch, MonoDevelop, and Mono for Android that allows us to write as much code that can run on both platforms.The following link is a recording on Cross Platform Development with MonoTouch and Mono for Android. I am guessing that the link only works in IE. That's out of my control.

• Breaking up the Workday– Overcoming the Workaholic Syndrome

  - by dwahlin

  Hi, my name’s Dan Wahlin and I’m a workaholic – I admit it. It’s good from the standpoint that I get a lot done but it also has a lot of cons associated with it as well that I’m not proud of. I literally can’t watch TV without feeling like I should be doing something more productive (although I have no problem going to see movies at a theater or watching sporting events – that’s my escape I guess). On vacation it’s sometimes difficult the first few days to just “let go” of work and enjoy the time with my family. I always feel like I should be checking email and following up with different business projects. Fortunately, my wife knows me really well after 17 years of marriage and “gently” restricts my usage of laptops and other gadgets while we’re out. She also reminds me that constantly burying my face in gadgets just isn’t cool and shows a distinct lack of self control. On a given day I typically put in between 12 (at a minimum) up to 16-18 hours working on projects. My company does .NET consulting (ASP.NET/jQuery, SharePoint and Silverlight) but we also do a lot in the training space so there’s always a client project, some new courseware or some other deliverable that has to be worked on. My normal process for handling that is to just work my butt off and see how much I can get done. That process has worked well for a long time but when you start realizing that your happiness comes from how much work you accomplished that day then you have a problem. That’s especially true if you have kids (which I do….two awesome boys). It’s almost as if working more hours feels like I’m more successful or something which is of course ridiculous. It may actually mean that I’m too distracted or disorganized. Lately I’ve realized that while I’m still productive and always meet my deadlines, I’m really burnt out by the afternoon and have lost some of the excitement I used to have. Part of that’s normal I think given that I’ve been doing this for close to 15 years now, but in thinking through it more I realized that I just need to get away from the desk and take a break. By far, the happiest time of my life was my childhood. Part of that was due to having awesome parents, having far less responsibility (a big factor I suspect), being able to hang-out with friends at school, playing sports, games, etc. but I think a big part of the overall happiness came from being outside a lot. I lived on my bike as a little kid and as I grew up I shared time between riding an ATV all over the place, shooting hoops on the basketball court, playing golf and working on a golf course (all outside work of course).  Being a software developer and trainer I generally spend 95% or more of my day indoors and only see the sun when driving from place to place or by looking out the window (that’s sad because I live in a suburb of Phoenix, AZ where it’s nearly always sunny). I haven’t looked into any scientific studies on the matter, but I’d be willing to bet there’s a direct correlation between overall productivity/happiness and being outside some throughout the day (sunny or not). But, I wasn’t sure what to do about it since I do have a lot of deadlines I need to meet after all. While talking with my wife last night I mentioned how I feel like I’m in a rut and want to get the “fun” back that I used to have. She immediately said that I need to start making time for breaks (a real quick fact – she’s a lot smarter than me and nearly always right). Of course my first thought was that I’d be less productive taking breaks. If I spend 2 hours just relaxing then I’m losing 2 hours of work. But, I thought about it more and realized that I’m probably less productive when I work 10+ hours and only take less than 30 minutes for a lunch break to relax a little. I bet my brain is screaming, “Please let me relax a little so I can figure out these problems you’re trying to resolve!”. So, starting today I’m going to try to break the workaholic habit and spend time outside of the office. That could mean sitting around outside, working out, golfing, or whatever. I’ve decided that no gadgets are allowed during that time and that I shouldn’t work for more than 4 hours straight without taking a break. I have no idea how my little “break the workaholic syndrome” experiment will go or how long it will last, but I’d be very interested in hearing from others on how they keep fresh and focused without working yourself to death. If you have any specific ideas, techniques or practices you follow please share them. There’s a lot more to life than work and some of us (and I’m thinking of myself specifically) need to take a long, hard look at what kind of balance we currently have. I’d hate to look back at my life when I’m 80 years old and say, “The only thing I did was work – I missed out on life!”.

• What light attenuation function does UDK use?

  - by ananamas

  I'm a big fan of the light attenuation in UDK. Traditionally I've always used the constant-linear-quadratic falloff function to control how "soft" the falloff is, which gives three values to play with. In UDK you can get similar results, but you only need to tweak one value: FalloffExponent. I'm interested in what the actual mathematical function here is. The UDK lighting reference describes it as follows: FalloffExponent: This allows you to modify the falloff of a light. The default falloff is 2. The smaller the number, the sharper the falloff and the more the brightness is maintained until the radius is reached. Does anyone know what it's doing behind the scenes?

• Good questions to ask a potential new boss?

  - by David Johnstone

  I first asked this question on Stack Overflow, but it turns out this is a better place for it. Imagine you were working as a software developer. Imagine that the manager of your team leaves and your company is looking for a replacement. Imagine that as part of the hiring process you had the opportunity to talk with him. You are not the only person doing an interview, and while it is not ultimately your decision whether or not to hire him, you do have an influence. What questions would you ask? What would you talk with him about?

• How to shorten brain context switch delay when need to use new technology\framework?

  - by gasan

  The problem is when I have to deal with a new framework\library\language it completely slows my work process, at first it's kind of shock, you're sitting on your place about a day doing nothing surfing the net, because you simply can't do anything even read docs, then, on the second day I realize that I definitely should do something and starting read about it, then I realize that I don't understand it, then I'm reading until I got feeling that I should show some results immediately and then I'm writing the code quite fast and the job doesn't seem to be difficult. Then job is done and I won't probably return to that technology\framework for a month or a year or never at all. And I will almost certainly forget almost everything about it after a month. To illustrate by checkpoints I experience: shock, long studying times, work with the new tech briefly, never use it afterwards, then I completely forget it. So what would be the solution here?

• Why is it java code indented as BSD KNF Style and C C++ code indented as Allman or BSD style?

  - by Caffeine

  I do understand that coding convention is a matter of preference, and that different coding conventions have different subtle advantages or shortcomings, and depending on what one wants, one should choose his/her style. But why is usually Java written where the opening brace is on the same line as the function definition of control statement, and in C or C++ the curly braces have a line of their own? BSD KNF style if (data != NULL && res > 0) { if (JS_DefineProperty(cx, o, "data", STRING_TO_JSVAL(JS_NewStringCopyN(cx, data, res)), NULL, NULL, JSPROP_ENUMERATE) != 0) { QUEUE_EXCEPTION("Internal error!"); goto err; } PQfreemem(data); } else { if (JS_DefineProperty(cx, o, "data", OBJECT_TO_JSVAL(NULL), NULL, NULL, JSPROP_ENUMERATE) != 0) { QUEUE_EXCEPTION("Internal error!"); goto err; } } Allman or BSD Style if (x == y) { something(); somethingelse(); } Courtesy: http://en.wikipedia.org/wiki/Indent_style

• Volume indicator issue after xubuntu 13.10 upgrade

  - by misterjinx

  Last night I decided to upgrade my system to the latest version of Xubuntu, 13.10. The process went fine, but now I'm facing this strange issue. There is no sound settings available in the settings manager window and the volume indicator looks like when the volume is muted, clicking the indicator being broken as well. The indicator looks like this: I tried to do a alsa force-reload followed by a restart of the computer, but didn't help. Any thoughts ? l.e. After some digging I found out that the volume control exists, so this must be a volume indicator issue.

• managing information/functionality on shared common project classes

  - by ilansch

  In my company, we have a common solution the contains common projects (2 projects so far, one for .net 3.5 and one for .net 4.5). My main problem is that during time, a lot of code is added, for example hosting a process as windows service is a class called ServiceManagement, But no one but the developer knows it, and if someone wants to use this shared class, he does not know it exist. So i am looking for a way to document and manage all the classes with tags, a 3rd party util/web util, that i can search for tags and maybe find common classes that i can use (if we keep all our code well-documented). Does anyone familiar with sort of tools ?

• Including slick2d or slick-util in maven build?

  - by BotskoNet

  I'm converting a project to lwjgl and trying to use slick-util as well. There's no slick-util maven repo anywhere (nor slick2d itself anymore). I've included local dependancies before using <dependency> <groupId>org.newdawn</groupId> <artifactId>slick</artifactId> <version>237</version> <scope>system</scope> <systemPath>${project.basedir}/lib/slick-util.jar</systemPath> </dependency> The maven package process runs without issue, but when I try to run the jar, it errors out with a ClassNotFoundException. There's no mention of slick-util in the manifest and I can't find out how to make my game load that jar properly. Side question: how do I ensure when I distribute my applications, the game properly installs these libraries?

• Upgrading Agent Controllers in Oracle Enterprise Manager Ops Center 12c

  - by S Stelting

  Oracle Enterprise Manager Ops Center 12c recently released an upgrade for Solaris Agent Controllers. In this week's blog post, we'll show you how to upgrade agent controllers. Detailed instructions about upgrading Agent Controllers are available in the product documentation here. This blog post uses an Enterprise Controller which is configured for connected mode operation. If you'd like to apply the agent update in a disconnected installation, additional instructions are available here. Step 1: Download Agent Controller Updates With a connected mode Ops Center installation, you can check for product updates at any time by selecting the Enterprise Controller from the left-hand Administration navigation tab. Select the right-hand Action link “Ops Center Downloads” to open a pop-up dialog displaying any new product updates. In this example, the Enterprise Controller has already been upgraded to the latest version (Update 1, also shown as build version 2076) so only the Agent Controller updates will appear. There are three updates available: one for Solaris 10 X86, one for Solaris 8-10 SPARC, and one for all versions of Solaris 11. Note that the last update in the screen shot is the Solaris 11 update; for details on any of the downloads, place your mouse over the information icon under the details column for a pop-up text region. Select the software to download and click the Next button to display the Ops Center license agreement. Review and click the check box to accept the license agreement, then click the Next button to begin downloading the software. The status screen shows the current download status. If desired, you can perform the downloads as a background job. Simply click the check box, then click the next button to proceed to the summary screen. The summary screen shows the updates to be downloaded as well as the current status. Clicking the Finish button will close the dialog and return to the Browser UI. The download job will continue to run in Ops Center and progress can still be viewed from the jobs menu at the bottom of the browser window. Step 2: Check the Version of Existing Agent Controllers After the download job completes, you can check the availability of agent updates as well as the current versions of your Agent Controllers from the left-hand Assets navigation tab. Select “Operating Systems” from the pull-down tab lets to display only OS assets. Next, select “Solaris” in the left-hand tab to display the Solaris assets. Finally, select the Summary tab in the center display panel to show which versions of agent controllers are installed in your data center. Notice that a few of the OS assets are not displayed in the Agent Controllers tab. Ops Center will not display OS instances which do not have an Agent Controller installation. This includes Enterprise Controllers and Proxy Controllers (unless the agent has been activated on the OS instance) and and OS instances using agentless management. For Agent Controllers which support an update, the version of agent software (in this example, 2083) appears to the right of the currently installed version. Step 3: Upgrade Your Agent Controllers If desired, you can upgrade agent controllers from the previous screen by selecting the desired systems and clicking the upgrade button. Alternatively, you can click the link “Upgrade All Agent Controllers” in the right-hand Actions menu: In either case, a pop-up dialog lets you start the upgrade process. The first screen in the dialog lets you choose the upgrade method: Ops Center provides three ways to upgrade agent controllers: Automatic Upgrade: If Agent Controllers are running on all assets, Ops Center can automatically upgrade the software to the latest version without requiring any login credentials to the system SSH using a single set of credentials: If all assets use the same login credentials, you can apply a single set to all assets for the upgrade process. The log-in credentials are the same ones used for asset discovery and management, which are stored in the Plan Management navigation tab under Credentials. SSH using individual credentials: If assets use different login credentials, you can select a different set for each asset. After selecting the upgrade method, click the Next button to proceed to the summary screen. Click the Finish button to close the pop-up dialog and start the upgrade job for the agent controllers. The upgrade job runs a series of tasks in parallel, and will upgrade all agents which have been selected. Once the job completes, the OS instances in your data center will be upgraded and running the latest version of Agent Controller software.
