  • Now Available: Profit November 2012

    - by user462779
    The November 2012 issue of Profit is now available. In the five years I've worked on Profit, there has been measurable interest in content related to project management. Stories featuring project management as a key component have resulted in extra clicks, likes, and RTs (for you Twitter users) from our readers. I've chatted about this with Oracle customers, partners, and experts and received an assortment of ideas about why this might be. This issue of Profit is a bit of a culmination of those conversations, and the trends that are driving interest in project management best practices. Also, two online developments for Profit: check out my newly relaunched blog, Editor's Notebook, at blogs.oracle.com/profit, where readers can get a peek at the development of each issue of Profit as it happens. We've also launched a new LinkedIn group for our social media-inclined readers. In this issue: Three Keys to Project Management What can organizations with world-class project management teach the rest of us? Strong Medicine Gilead Sciences simplifies business processes to establish a foundation for continued growth. Architects of Reform Enterprise architecture plays an essential role in establishing Oregon as a leader in healthcare reform. Answering the Call Turkcell CIO Ilker Kuruoz finds IT-powered growth and innovation to be the calling card for success. Projected Results Sound project management practices and technology can have an immediate impact on the bottom line. Preparing for Impact Plans for dealing with enterprise information will define the big data winners. Is one issue of Profit not enough to get you through to February? Visit the Profit archives, or follow @OracleProfit on Twitter for a daily dose of enterprise technology news from Profit.

  • A Quarter Century of SPARC

    - by kemer
    You might have missed an interesting milestone: the 25th anniversary of SPARC. Twenty-five years! Almost 40% of my life: humbling, maybe a little scary. When I joined Sun Microsystems in 1988, SPARC was just starting to shake things up. The next year we introduced the SPARCstation 1, which had basically triple the performance of our Motrolla-based Sun–3 systems. Not too long after that, our competition began a campaign of “SPARC is dead.” We really distressed them with our success, in spite of our small size. “It won’t last.” “It can’t last!” So they told themselves. For a stroll down memory lane take a look at this page. I remember the sales meeting we had in Atlanta to internally announce the SPARCstation 1. Sun hadn’t really hit the big times, yet. Our much bigger competitors viewed us as an ill-mannered pest, certain of our demise. And, why wouldn’t they be certain: other startups more our size, such as Apollo (remember them?), Silicon Graphics (they fought the good fight!), and the incredibly cool Symbolics are memories. Wait! There was also a BIG company, DEC, who scoffed at us: they are history, too. In fact, we really upset them with what was supposed to be an internal-only video production that was a take-off on Bruce Lee movies, in which we battled the evil Doctor DEC – complete with computer mice (or is that “mouses”?) wielded like nun chucks with the new SPARCstation 1 somehow in the middle of everything. The memory is vivid, but the details hazy. After all, that was almost a quarter century ago. So, here’s to Oracle’s SPARC: still going strong after all these years. – Kemer

  • Any mates have same plan as me. Focust on tech whole life, no wife, no kids [closed]

    - by Anders Lind
    I am about 30 years old, c++ programmer. Kernel hacker. Living in east coast US. Day by day, night by night. I am in front of my monitor, typing code on my hhkb, scratching idea on my notebook. In my spare time, I play piano sometimes. Go to some classical concert once a month. Basically having a happy life. One concern is I dont have gf. I dont have wife nor kids. My parents start to worry about this. Occasionally they will ask my status. they wont tell me to do anything. But I can see their worries. So, my question is, is my life normal? How many mates think same as me? (I only know rms is single, has no kids, and having a happy life. But I am way worse than him. compare to him, I am nothing. If I am as successful as him. I won;t ask this question here.)

  • Optimized algorithm for line-sphere intersection in GLSL

    - by fernacolo
    Well, hello then! I need to find intersection between line and sphere in GLSL. Right now my solution is based on Paul Bourke's page and was ported to GLSL this way: // The line passes through p1 and p2: vec3 p1 = (...); vec3 p2 = (...); // Sphere center is p3, radius is r: vec3 p3 = (...); float r = ...; float x1 = p1.x; float y1 = p1.y; float z1 = p1.z; float x2 = p2.x; float y2 = p2.y; float z2 = p2.z; float x3 = p3.x; float y3 = p3.y; float z3 = p3.z; float dx = x2 - x1; float dy = y2 - y1; float dz = z2 - z1; float a = dx*dx + dy*dy + dz*dz; float b = 2.0 * (dx * (x1 - x3) + dy * (y1 - y3) + dz * (z1 - z3)); float c = x3*x3 + y3*y3 + z3*z3 + x1*x1 + y1*y1 + z1*z1 - 2.0 * (x3*x1 + y3*y1 + z3*z1) - r*r; float test = b*b - 4.0*a*c; if (test >= 0.0) { // Hit (according to Treebeard, "a fine hit"). float u = (-b - sqrt(test)) / (2.0 * a); vec3 hitp = p1 + u * (p2 - p1); // Now use hitp. } It works perfectly! But it seems slow... I'm new at GLSL. You can answer this questions in two ways: Tell me there is no solution, showing some proof or strong evidence. Tell me about GLSL features (vector APIs, primitive operations) that makes the above algorithm faster, showing some example. Thanks a lot!

  • Internet Timeouts with TP-Link TL-WN821N v2 wireless usb stick

    - by user1622959
    A short time after accessing the internet, the browser/download times out. Before the timeout, the internet works OK briefly; afterwards, the wireless is still connected with a strong signal, but every internet access results in a timeout. When I leave the PC for a while, the internet is back just to timeout again as soon as I start using it. The same happens when I reconnect to the router. Also, when I surf the internet, it takes a couple of minutes until the timeout, but when I download something, it times out in a matter of seconds. The wireless adapter works just fine in Windows and internet via ethernet cable works just fine in Ubuntu. Does anyone have the same problem or knows a solution. I use Ubuntu 12.10 x64. The problem occurs since I installed ubuntu (which was a few days ago). Here some stuff that might be usefull: serus@serus-Ubuntu-PC:~$ lsusb Bus 002 Device 002: ID 0cf3:1002 Atheros Communications, Inc.

  • The Importance of Fully Specifying a Problem

    - by Alan
    I had a customer call this week where we were provided a forced crashdump and asked to determine why the system was hung. Normally when you are looking at a hung system, you will find a lot of threads blocked on various locks, and most likely very little actually running on the system (unless it's threads spinning on busy wait type locks). This vmcore showed none of that. In fact we were seeing hundreds of threads actively on cpu in the second before the dump was forced. This prompted the question back to the customer: What exactly were you seeing that made you believe that the system was hung? It took a few days to get a response, but the response that I got back was that they were not able to ssh into the system and when they tried to login to the console, they got the login prompt, but after typing "root" and hitting return, the console was no longer responsive. This description puts a whole new light on the "hang". You immediately start thinking "name services". Looking at the crashdump, yes the sshds are all in door calls to nscd, and nscd is idle waiting on responses from the network. Looking at the connections I see a lot of connections to the secure ldap port in CLOSE_WAIT, but more interestingly I am seeing a few connections over the non-secure ldap port to a different LDAP server just sitting open. My feeling at this point is that we have an either non-responding LDAP server, or one that is responding slowly, the resolution being to investigate that server. Moral When you log a service ticket for a "system hang", it's great to get the forced crashdump first up, but it's even better to get a description of what you observed to make to believe that the system was hung.

  • Raspberry Pi, Time Capsule Progress

    - by Richard Jones
    So by way of an update. I thought all was good with my Raspberry Pi, Debian and Netatalk Apple Time Capsule Clone. However something very strange going on. Although I could backup my Mac's + PC's fine to Raspberry Pi with external USB HD; strangely with RPI running, I couldn't use AirPlay. I found myself unable to play anything from Mac to Apple TV. So after lots of trying to make this work, I about turned and finally went out and got myself a 2TB Apple Time Capsule. More cash than I would want to spend on anything like this, but Apple you got me. I would like to offer a top tip, which maybe goes a small way to justifying silly expenditure... You can easily add a USB HD to any Time Capsule. I've just added a 3 TB external USB HD, giving me a 5 TB of total backup grunt. 3 TB External USB HD, was peanuts by comparison to Apple kit. So all working, its all solid as you'd expect.Apple 2, maybe me .5. But strong, solid backups now happening, without hassle (but a bit of a credit card bill to follow)

  • Is Oracle Database Appliance (ODA) A Best Kept Secret?

    - by Ravi.Sharma
    There is something about Oracle Database Appliance that underscores the tremendous value customers see in the product. Repeat purchases. When you buy “one” of something and come back to buy another, it confirms that the product met your expectations, you found good value in it, and perhaps you will continue to use it. But when you buy “one” and come back to buy many more on your very next purchase, it tells something else. It tells that you truly believe that you have found the best value out there. That you are convinced! That you are sold on the great idea and have discovered a product that far exceeds your expectations and delivers tremendous value! Many Oracle Database Appliance customers are such larger-volume-repeat-buyers. It is no surprise, that the product has a deeper penetration in many accounts where a customer made an initial purchase. The value proposition of Oracle Database Appliance is undeniably strong and extremely compelling. This is especially true for customers who are simply upgrading or “refreshing” their hardware (and reusing software licenses). For them, the ability to acquire world class, highly available database hardware along with leading edge management software and all of the automation is absolutely a steal. One customer DBA recently said, “Oracle Database Appliance is the best investment our company has ever made”. Such extreme statements do not come out of thin air. You have to experience it to believe it. Oracle Database Appliance is a low cost product. Not many sales managers may be knocking on your doors to sell it. But the great value it delivers to small and mid-size businesses and database implementations should not be underestimated.

  • Data recovery on Ubuntu 11.10?! (after crashing with Seagate 320GB)

    - by Sam
    Just installed 11.10 last week and decided to transfer iTunes music (from Windows dual boot) to my Seagate 320GB. I left it in, restarted, clicked Ubuntu at the boot screen, and then it froze after a few lines of code! I think I got to 3.7086 or something before I pressed CTRL+ALT+DEL and the system restarted after another few lines of code. I am completely new to Ubuntu so after Googling, I made a live CD with 10.04, the most stable release I've heard, and I'm typing this from there now. However, when I go to mount my partition, only the Windows Vista partition (308GB) is there! It has all my Windows files but my Ubuntu 11.10 ones are nowhere to be found. I need to restore these pictures I transferred from my camera using Shotwell the other day... any help is appreciated! p.s. 11.10 has never crashed on me in my trial week, so I'm guessing it's the Seagate hard drive's fault. However, now I'm running it on 10.04 and it works fine.

  • Student Life in Nigeria

    - by FelixWehmeyer
    They say that the Nigerian way of life involves being able and ready to succeed in life no matter the obstacles. My name is Olawale Obasola, graduated from Covenant University ’07 and presently working as a graduate consultant in Oracle. I will give you an insight into the student life in Nigeria. Nowadays, being a graduate in Nigeria is not the easiest thing; the life after graduation is much harder than one would normally imagine. I guess it isn’t helped with the Economical uproar of the last few years but it’s as grueling as it can get.  Also the Upper vs Lower class phenomena makes the journey a little too much hurried as it is easier to lose one’s way. Joining Oracle is a dream come-true as it further enhances my stance of taking Technology to the core of Nigeria. My initial perception about joining Oracle is that am going to be monitored every single second and my life would practically revolve around work but ever since I stepped in here, it has been an amazing experience. As much as the work can be stressful at times, it’s also the best place I have ever worked in and the atmosphere is great. My team is the best Pre-Sales team in the region and I gain invaluable knowledge every minute, we have a bond and understanding that helps propel each other to achieve more. The Life of a Nigerian graduate isn’t a bed of roses but I have a strong will and personality to emerge from any hardship to succeed. We show the true strength and spirit of Africa, we never give up and would never settle for anything less than the best.

  • Greeter login screen cropped login options in 12.04

    - by ammianus
    I have a pretty newly installed Ubuntu 12.04, using Unity. My external monitor is 1920x1080 max resolution. In the Unity desktop itself everything looks great. I have an NVidia graphics card. When I start my computer and get to the Unity greeter login screen the display is oddly formatted and the resolution seems off. It looks like a zoomed view on the larger 1920x1080 screen. As such it crops the login options off to the left hand side of the screen. So I can only just see the edge of the password box for the user I want to log in with. I can log in with one account by default by blindly typing the password, but I am unable to switch to other accounts. Is there anything I can do to fix the log in screen display so that I can see the normal login options? Note: I first noticed it when I changed my desktop background and the next time I logged in I saw the issue.

  • A fix for the design time error in MVVM Light V4.1

    - by Laurent Bugnion
    For those of you who installed V4.1 of MVVM Light and created a project for Windows Phone 8, you will have noticed an error showing up in the design surface (either in Visual Studio designer, or in Expression Blend). The error says: “Could not load type ‘System.ComponentModel.INotifyPropertyChanging’ from assembly ‘mscorlib.extensions’” with additional information about version numbers. The error is caused by an incompatibility between versions of System.Windows.Interactivity. Because this assembly is strongly named, any version incompatibility is causing the kind of error shown here (for an interesting discussion on the strong naming issue, see this thread on Codeplex). I managed to resolve the issue for Windows Phone 8 and will publish a cleaned up installer next week. In the mean time, in order to allow you to continue development, please follow the steps: Download the new DLLs zip package (MVVMLight_V4_1_25_WP8). Right click on the Zip file and select Properties from the context menu. Press the “Unblock” button (if available) and then OK. Right click again on the zip package and select “Extract all…”. Select a known location for the new DLLs. Open the MVVM Light project with the design time error in Visual Studio 2012. Open the References folder in the Solution Explorer. Select the following DLLs: GalaSoft.MvvmLight.dll, GalaSoft.MvvmLight.Extras.dll, Microsoft.Practices.ServiceLocation.dll and System.Windows.Interactivity.dll. Press “delete” and confirm to remove the DLLs from your project. Right click on References and select Add Reference from the context menu. Browse to the folder with the new DLLs. Select the four new DLLs and press OK. Rebuild your application, and open it again in Blend or in the Visual Studio designer. The error should be gone now. In the next few days, as time allows, I will publish a new MSI containing a fixed version of the DLLs as well as a few other improvements. This quick fix should however allow you to continue working on your Windows Phone 8 projects in design mode too.   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

  • ERP/CRM Systems. Desktop Based ? Web based? [closed]

    - by Parhs
    I have seen 2-3 ERPs in action. I am wondering what is better. Desktop based application or webbased displayed on a browser. My first experience was with a web based ERP when i was 14 years old.. It was web based and terribly slow... For most simple task you had to do lots of clicks... no keyboard support ..... Pages took ages to load. Last year I worked for migrating to a newer computer some old terminal based cobol application. The computer that worked till today and still has no problem was from 1993. The user interface ofcourse was textbased.. The speed that guys placed orders was amazing! just typing the name of the customer , then 5-10 keys to add a product to order.... Comparing to this ERP the page for placing orders Link (click sales orders) seems terribly slow to add a product... No keyboard shortcut works to save what you added and generally I believe you need 4 times more time to place an order compared to the text interface... Having to use both mouse and keyboard for this task is BAD and sadistic... So how can the heck these people ever use a system like that ??? So in the long run desktop application seems the only way... Of course browsers support shortcuts but the way to overide the defaults that browsers uses isn't cross compatible... That is a huge problem. Finnaly, if we MUST/forced use cloud in near future what about keyboard shortcuts?? I feel confused... I have seen converters of desktop applications to browser applications but are SLOW as hell... The question is what about user friendliness? What kind of application would you use?

  • Good books or tutorials on building projects without an IDE?

    - by CodexArcanum
    While I'm certainly under no illusions that building software without an IDE is possible, I don't actually know much about doing it well. I've been using graphical tools like Visual Studio or Code::Blocks so long that I'm pretty well lost without them. And that really stinks when I want to change environments or languages. I couldn't really do anything in D until someone made a Visual Studio plugin, and now that I'm trying to do more development on Mac, I can't use D again because the XCode plugins don't work. I'm sick of being lost when I see a .make file and having no idea what I'm supposed to do with a folder full of source files. People can't be compiling them one by one using the console and then linking them one by one. You'd spend more time typing file names than code. So what are the automation and productivity tools of the non-IDE user? How do you manage a project when you're writing all the code in emacs or vim or nano or whatever? I would love it if there was a book or a guide online that spells some of this out.

  • Why can't I run any Android NDK commands?

    - by TheBuzzSaw
    I had been running Mint 12 before, and everything was working there. I switched to Ubuntu 12.04, and now I am very frustrated. When I run ndk-build, I get /home/buzz/ndk/prebuilt/linux-x86/bin/make: not found So, I changed to that folder directly. When I type in ./make, I get bash: ./make: No such file or directory Typing ls clearly shows the file where I am! I did some hacking around (pointing to external tools) to get past each error (just to experiment), and I ran into this! /home/buzz/ndk/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc: Command not found Why? Why are all these files unable to be found? As I said above, this was all working just fine in another distro. What changed? What's extra frustrating is that if I push TAB to auto-complete, it works. So, the file is clearly there (and clearly marked with execution permissions). So, why can't it be found?

  • Structure of a .NET Assembly

    - by Om Talsania
    Assembly is the smallest unit of deployment in .NET Framework.When you compile your C# code, it will get converted into a managed module. A managed module is a standard EXE or DLL. This managed module will have the IL (Microsoft Intermediate Language) code and the metadata. Apart from this it will also have header information.The following table describes parts of a managed module.PartDescriptionPE HeaderPE32 Header for 32-bit PE32+ Header for 64-bit This is a standard Windows PE header which indicates the type of the file, i.e. whether it is an EXE or a DLL. It also contains the timestamp of the file creation date and time. It also contains some other fields which might be needed for an unmanaged PE (Portable Executable), but not important for a managed one. For managed PE, the next header i.e. CLR header is more importantCLR HeaderContains the version of the CLR required, some flags, token of the entry point method (Main), size and location of the metadata, resources, strong name, etc.MetadataThere can be many metadata tables. They can be categorized into 2 major categories.1. Tables that describe the types and members defined in your code2.

    When creating a product which will inherently suffer from regression due to OS updates, which of these is the preferable approach when trying to reduce maintenance cost and the likelihood of needing refactoring, when considering the task of interpreting system state and settings for a lay user? Delegate the responsibility of interpreting the results of inspecting the system to the modules which perform these tasks, or, Separate the concerns of interpretation and inspection into two modules? The first obviously creates a blob in which a lot of code would be verbose, redundant, and hard to grok; the second creates a strong coupling in which the interpretation module essentially has to know what it expects from inspection routines and will have to adapt to changes to the OS just as much as the inspection will. I would normally choose the second option for the separation of concerns, foreseeing the possibility that inspection routines could be re-used, but a developer updating the product to deal with a new OS feature or something would have to not only write an inspection routine but also write an interpretation routine and link the two correctly - and it gets worse for a developer who has to change which inspection routines are used to get a certain system setting, or worse yet, has to fix an inspection routine which broke after an OS patch. I wonder, is it better to have to patch one package a lot or two packages, each somewhat less so?

  • Is it better to specialize in a single field I like, or expand into other fields to broaden my horizons?

    - by Oak
    This is a dilemma about which I have been thinking for quite a while. I'm a graduate student and my topics of interest are programming language design, code analysis, compilation, etc. So far, this field has been very interesting and rewarding for me, so I was thinking about finding a job in that field and continuing to specialize in it. I feel like it's a relatively solid field which won't "get out of style" anytime soon. I've always thought that in such complex fields it's better to be a real expert than just another guy who superficially understand what the experts are talking about. On the other hand, I feel that by specializing this way I really limit my future option. I have always been a strong believer in multidisciplinary approaches to problems. Maybe I should go search for a general programming job in which I could gain experience in other fields, as well as occasionally apply my favorite field for solving problems. Specializing in only one or two fields can prevent me from thinking outside the box and cause stagnation. I would really like to hear more opinions about this choice. The truth is I'm already leaning towards one of the choices, so basic psychology says nothing will change my mind, but I would still love to hear some feedback.

  • You've been working on a platform for as long as you remember. Not anymore. How does it feel?

    - by Shinnok
    How does it feel to work on a platform for as long as you remember, you've been encouraged to innovate, to improve and give all in day and night for that platform, be it either an operating system, a hardware architecture or a software framework/library and then be forced to switch bases because that platform has been abandoned over the night? It has happened before, many times, for eg. to SGI/IRIX and more recently to SUN/Open Solaris and now Nokia/Symbian. Have you been part of such a shift? If so then please share the story and describe your feelings at that time and if it is the case, how did you manage the situation? Reorientation? Giving up on the field and turned to other things you've been constantly putting aside like family? Many did so(for eg. people at Netscape). You may not think of it being such a big deal, but it is, after you've been working 10 to 20+ years on a platform/technology and then be faced to switch your expertise and mindset, the feeling tends to become really strong and some people really give up this crazy field and start enojoying a normal life. Would love to hear your stories.

  • Efficient path-finding in free space

    - by DeadMG
    I've got a game situated in space, and I'd like to issue movement orders, which requires pathfinding. Now, it's my understanding that A* and such mostly apply to trees, and not empty space which does not have pathfinding nodes. I have some obstacles, which are currently expressed as fixed AABBs- that is, there is no unbounded "terrain" obstacle. In addition, I expect most obstacles to be reasonably approximable as cubes or spheres. So I've been thinking of applying a much simpler pathfinding algorithm- that is, simply cast a ray from the current position to the target position, and then I can get a list of obstacles using spatial partitioning relatively quickly. What I'm not so sure about is how to determine the part where the ordered unit manoeuvres around the obstacles. What I've been thinking so far is that I will simply use potential fields- that is, all units will feel a strong repulsive force away from each other and a moderate force towards the desired point. This also has the advantage that to issue group orders, I can simply order a mid-level force towards another entity. But this obviously won't achieve the optimal solution. Will potential fields achieve a reasonable approximation given my parameters, or do I need another solution?
