  • Generalize, or Fix The Problem?

    - by Droogans
    Which of these two programmers is "better", from a managerial standpoint? The first programmer is Albert. You tell Al to make a system that will pass you the salt at the dinner table. He does it in less than a day. It works fine. The second programmer is Ben. Ben is told to make a program to pass the salt, and after two days, he's still working on it. It will save time in the long run...if you need pepper, ketchup, etc. There isn't any clear indication that there will be a need for this, but it's not improbable. Who's the better programmer to have working under you, as a manager?

  • Accidentally uninstalled Ubuntu 14.04 system settings. How to get them back?

    - by Dan
    Somehow, cleaning up useless software (using software center), I uninstalled Ubuntu "system settings". I did this by mistake. Now I fail to find system settings application using software center (and there are so many items in history...). It seems strange to me because usually when I try to uninstall something critical (system testing for example), the dependencies manager tells me It will uninstall the whole desktop system then. I am sure I did not have that warning. So I need the name of the software to install or a command line command rather than a system restore to get it back. Very interesting thing. If you ever want to play with this and reproduce it, you will be confused to see Ubuntu Mobile system settings instead! Yes, mobile network and touchscreen settings! Happy pre-release viewing!

  • Is it normal for programmer to work on multiple projects simultaneously.

    - by gasan
    On a current job I have 2 projects to work on. First is very huge system and the second one is smaller but it also big (first project is being developed for 12 years, second for 4 years). At first I was working only on first project and was trying to get used to it. Then I was moved to second project and tried there, so my knowledge about first project became shady. Now I have to work on both projects at the same time. It's very hard for me because despite they both use java, they use different frameworks and the amount of code and business-logic to understand is very big so I really can't hold both that projects in my head. Is it normal and I should get used to it, although my expertise became very squashy, what won't happen if I would work only on a single project? Or should I raise a concern or maybe change employer?

  • UK Oracle User Group Event: Trends in Identity Management

    - by B Shashikumar
    As threat levels rise and new technologies such as cloud and mobile computing gain widespread acceptance, security is occupying more and more mindshare among IT executives. To help prepare for the rapidly changing security landscape, the Oracle UK User Group community and our partners at Enline/SENA have put together an User Group event in London on Apr 19 where you can learn more from your industry peers about upcoming trends in identity management. Here are some of the key trends in identity management and security that we predicted at the beginning of last year and look how they have turned out so far. You have to admit that we have a pretty good track record when it comes to forecasting trends in identity management and security. Threat levels will grow—and there will be more serious breaches:   We have since witnessed breaches of high value targets like RSA and Epsilon. Most organizations have not done enough to protect against insider threats. Organizations need to look for security solutions to stop user access to applications based on real-time patterns of fraud and for situations in which employees change roles or employment status within a company. Cloud computing will continue to grow—and require new security solutions: Cloud computing has since exploded into a dominant secular trend in the industry. Cloud computing continues to present many opportunities like low upfront costs, rapid deployment etc. But Cloud computing also increases policy fragmentation and reduces visibility and control. So organizations require solutions that bridge the security gap between the enterprise and cloud applications to reduce fragmentation and increase control. Mobile devices will challenge traditional security solutions: Since that time, we have witnessed proliferation of mobile devices—combined with increasing numbers of employees bringing their own devices to work (BYOD) — these trends continue to dissolve the traditional boundaries of the enterprise. This in turn, requires a holistic approach within an organization that combines strong authentication and fraud protection, externalization of entitlements, and centralized management across multiple applications—and open standards to make all that possible.  Security platforms will continue to converge: As organizations move increasingly toward vendor consolidation, security solutions are also evolving. Next-generation identity management platforms have best-of-breed features, and must also remain open and flexible to remain viable. As a result, developers need products such as the Oracle Access Management Suite in order to efficiently and reliably build identity and access management into applications—without requiring security experts. Organizations will increasingly pursue "business-centric compliance.": Privacy and security regulations have continued to increase. So businesses are increasingly look for solutions that combine strong security and compliance management tools with business ready experience for faster, lower-cost implementations.  If you'd like to hear more about the top trends in identity management and learn how to empower yourself, then join us for the Oracle UK User Group on Thu Apr 19 in London where Oracle and Enline/SENA product experts will come together to share security trends, best practices, and solutions for your business. Register Here.

  • How to verify system using right GPU, after system reset [duplicate]

    - by Antoros
    This question already has an answer here: Is my mobile AMD card being used? 2 answers OS: Windows 8 CPU: Intel® Core™ i7 Processor 3635QM GPU 1 : Intel HD Graphics 4000 GPU 2 : AMD Radeon™ HD 8870M other info: System Spects Problem: im unsure that CCC is using AMD card instead of Intel's, i have encountered several issues since updating to 8.1 and i don't know what to do What happened: Installed 8.1 patch first day After 1 minute of use, BBSOD, windows never loaded again System restore wouldnt recognize 8.0 restore points i did a system reset to windows 8 since the laptop was only 3 weeks old System Broke, it did restore to factory BUT kept the registry almost intact, i had to install almost everything again, since the factory drivers where working with the updated one's registry and several problems CCC Broke too <- What i've already done Installing new drivers on top of old ones didnt work, so i used AMD uninstaller first Uninstalled and Re-installed Intel's HD Graphics Driver Tried to install mobile center, but AMD told me that it wasnt compatible (even if thats the only driver that they provide via their page as seen Here) Tried to use Auto-Detect, couldnt install driver because card was disabled because it didnt have the drivers... (see what they did here?) Had to use a workaround with Samsung Update, the driver didnt appear as download so had to use search and downloaded the driver manually. Now the graphic card appears on device manager and catalyst but as 8800 series (not exact model), and cant check the card with neither dxdiag/GPU-z/HWMonitor when right-clicking on CCC only Intel card appears launching a game and using as "high performance" would speed it up a little but i cant be sure How to verify its working properly? HWMonitor wont show AMD card even when set to high performance Latest GPU-Z wont work because a problem with Intel's, and legacy ones wont either what can I do now? I don't even know if I fixed my problem or not, and i also want to to use Adobe Premier with it, and its locked (the option to run it with the amd card not intels) Edit: now it seems to work, but cant change the setting for adobe Premiere and other programs that i Need to

  • Oracle's PeopleSoft Customer Advisory Boards Convene to Discuss Roadmap at Pleasanton Campus

    - by john.webb(at)oracle.com
    Last week we hosted all of the PeopleSoft CABs (Customer Advisory Boards) at our Pleasanton Development Center to review our detailed designs for future Feature Packs, PeopleSoft 9.2, and beyond. Over 150 customers from 79 companies attended representing a variety of industries, geographies, and company sizes. The PeopleSoft team relies heavily on this group to provide key input on our roadmap for applications as well as technology direction. A good product strategy is one part well thought out idea with many handfuls of customer validation, and very often our best ideas originate from these customer discussions. While the individual CABs have frequent interactions with our teams, it's always great to have all of them in one place and in person. Our attendance was up from last year which I attribute to two things: (1) More interest as a result of PeopleSoft 9.1 upgrade; (2) An improving economy allowing for more travel. Maybe we should index the second item meeting-to-meeting and use it as a market indicator - we'll see! We kicked off the day one session with an overview of the PeopleSoft Roadmap and I outlined our strategy around Feature Packs and PeopleSoft 9.2. Given the high adoption rate of PeopleSoft 9.1 (over 4x that of 9.0 given the same time lapse since the release date), there was a lot of interest around the 9.1 Feature Packs as a vehicle for continuous value. We provided examples of our 3 central design themes: Simplicity, Productivity, and lower TCO, including those already delivered via Feature Packs in 2010. A great example of this is the Company Directory feature in PeopleSoft HCM. The configuration capabilities and the new actionable links our CAB advised us on last Spring were made available to all customers late last year. We reviewed many more future Navigation changes that will fundamentally change the way users interact with PeopleSoft. Our old friend, the menu tree, is being relegated from center stage to a bit part, with new concepts like Activity Guides, Train Stops, Related Actions, Work Centers, Collaborative Workspaces, and Secure Enterprise Search bringing users what they need in a contextual, role based manner with fewer clicks. Paco Aubrejuan, our PeopleSoft GM, and Steve Miranda, the SVP for Fusion Applications, then discussed our plans around Oracle's Application Investment Strategy.  This included our continued investment in developing both PeopleSoft and Fusion as well as the co-existence strategy with new Fusion Apps integrating to PeopleSoft Apps. Should you want to view this presentation, a recording is available. Jeff Robbins, our lead PeopleTools Strategist, provided the roadmap for PeopleTools and discussed our continuing plan to deliver annual releases to further evolve the user experience. Numerous examples were highlighted with the Navigation techniques I mentioned previously. Jeff also provided a lot of food for thought around Lifecycle Management topics and how to remain current on releases with a  lower cost of ownership. Dennis Mesler, from Boise, was the guest speaker in this slot, who spoke about the new PeopleSoft Test Framework (PTF). Regression Testing is a key cost component when product updates are applied. This new tool (which is free to all PeopleSoft customers as part of PeopleTools 8.51) provides a meta data driven approach to recording and executing test scripts. Coupled with what our Usage Monitor enables, PTF provides our customers a powerful tool to lower costs and manage product updates more efficiently and at the time of their choosing. Beyond the general session, we broke out into the individual CABs: HCM, Financials, ESA/ALM, SRM, SCM, CRM, and PeopleTools/ Technology. A day and half of very engaging discussions around our plans took place for each product pillar. More about that to follow in future posts.      We capped the first day with a reception sponsored by our partners: InfoSys, SmartERP (represented by Doris Wong), and Grey Sparling  Solutions (represented by Chris Heller and Larry Grey). Great to see these old friends actively engaged in the very busy PeopleSoft ecosystem!   Jeff Robbins previews the roadmap for PeopleTools with the PeopleSoft CAB

  • Project management, timesheet and planning software

    - by hfidgen
    Hiya, I'm trying to find an integrated PM solution which will give my business all of the following: Timesheeting so we can track time spent on tasks Holiday planner (integrated with timesheet and project management Project management tool, integrating the above, with milestones, gantt chart, dependancies etc. Forecasting ability (nice to have, but not a requirement) Reporting capability - especially time spent on projects, costs etc. Now yeah, that's quite a lot of functionality, I appreciate that! But currently we've got 3 systems, none of which really talk to each other and it's a right headache. So far we've looked at: OpenWorkbench - not enough features Basecamp - not enough features and too reliant on online MS Project - too expensive? Can anyone throw some other hats into the ring which maybe I've not heard about? Really interested to hear how other people have approached this, it's not an unusual business requirement! Thanks!

  • Server Core remote management from Windows 7 machine

    - by Robert Koritnik
    I've installed Remote Server Administration Tools for Windows 7 because I would like to administer my Windows Server 2008 R2 Server Core machine. The problem that I'm getting when I try to run Server Manager is: Connecting to remote server failed with the following error message: Access is denied. For more information, see the about_Remote_Troubleshooting Help topic. This is what I've done so far: I'm running WinRM service on both machines (Server and Window 7) I've added my server to trusted hosts on my Windows 7 machine: winrm set winrm/config/client @{TrustedHosts="WINSRV2"} I've added registry entry on Windows 7 machine: reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f I've enabled Remote Management inbound rule on server firewall using CoreConfigurator 2.0 both machines are in the same subnet and when I search for network machines on Windows 7 I see my server. Question What else should I do to make it work? I would like to run several different remote management tools against my server machine.

  • Windows Server 2008 R2 stuck at System Recovery Options

    - by Magnus
    One of my Windows Server 2008 R2 server has started to go into System Recovery Options at reboot. I have tried to let it go through a System Image Recovery, which it says completes successfully. But after reboot it again wants to do a system recovery. Safe mode doesn't work; it still wants to do a system recovery. Putting in the install DVD trying to do a repair actually brings up the very same System Revoery dialog again. Nothing has changed configuration wise. Any ideas?

  • Identity Globe Trotters (Sep Edition): The Social Customer

    - by Tanu Sood
    Welcome to the inaugural edition of our monthly series - Identity Globe Trotters. Starting today, the last Friday of every month, we will explore regional commentary on Identity Management. We will invite guest contributors from around the world to share their opinions and experiences around Identity Management and highlight regional nuances, specific drivers, solutions and more. Today's feature is contributed by Michael Krebs, Head of Business Development at esentri consulting GmbH, a (SOA) specialized Oracle Gold Partner based in Ettlingen, Germany. In his current role, Krebs is dealing with the latest developments in Enterprise Social Networking and the Integration of Social Media within business processes.  By Michael Krebs The relevance of "easy sign-on" in the age of the "Social Customer" With the growth of Social Networks, the time people spend within those closed "eco-systems" is growing year by year. With social networks looking to integrate search engines, like Facebook announced some weeks ago, their relevance will continue to grow in contrast to the more conventional search engines. This is one of the reasons why social network accounts of the users are getting more and more like a virtual fingerprint. With the growing relevance of social networks the importance of a simple way for customers to get in touch with say, customer care or contract departments, will be crucial for sales processes in critical markets. Customers want to have one single point of contact and also an easy "login-method" with no dedicated usernames, passwords or proprietary accounts. The golden rule in the future social media driven markets will be: The lower the complexity of the initial contact, the better a company can profit from social networks. If you, for example, can generate a smart way of how an existing customer can use self-service portals, the cost in providing phone support can be lowered significantly. Recruiting and Hiring of "Digital Natives" Another particular example is "social" recruiting processes. The so called "digital natives" don´t want to type in their profile facts and CV´s in proprietary systems. Why not use the actual LinkedIn profile? In German speaking region, the market in the area of professional social networks is dominated by XING, the equivalent to LinkedIn. A few weeks back, this network also opened up their interfaces for integrating social sign-ons or the usage of profile data for recruiting-purposes. In the European (and especially the German) employment market, where the number of young candidates is shrinking because of the low birth rate in the region, it will become essential to use social-media supported hiring processes to find and on-board the rare talents. In fact, you will see traditional recruiting websites integrated with social hiring to attract the best talents in the market, where the pool of potential candidates has decreased dramatically over the years. Identity Management as a key factor in the Customer Experience process To create the biggest value for customers and also future employees, companies need to connect their HCM or CRM-systems with powerful Identity management solutions. With the highly efficient Oracle (social & mobile enabling) Identity Management solution, enterprises can combine easy sign on with secure connections to the backend infrastructure. This combination enables a "one-stop" service with personalized content for customers and talents. In addition, companies can collect valuable data for the enrichment of their CRM-data. The goal is to enrich the so called "Customer Experience" via all available customer channels and contact points. Those systems have already gained importance in the B2C-markets and will gradually spread out to B2B-channels in the near future. Conclusion: Central and "Social" Identity management is key to Customer Experience Management and Talent Management For a seamless delivery of "Customer Experience Management" and a modern way of recruiting the best talent, companies need to integrate Social Sign-on capabilities with modern CX - and Talent management infrastructure. This lowers the barrier for existing and future customers or employees to get in touch with sales, support or human resources. Identity management is the technology enabler and backbone for a modern Customer Experience Infrastructure. Oracle Identity management solutions provide the opportunity to secure Social Applications and connect them with modern CX-solutions. At the end, companies benefit from "best of breed" processes and solutions for enriching customer experience without compromising security. About esentri: esentri is a provider of enterprise social networking and brings the benefits of social network communication into business environments. As one key strength, esentri uses Oracle Identity Management solutions for delivering Social and Mobile access for Oracle’s CRM- and HCM-solutions. …..End Guest Post…. With new and enhanced features optimized to secure the new digital experience, the recently announced Oracle Identity Management 11g Release 2 enables organizations to securely embrace cloud, mobile and social infrastructures and reach new user communities to help further expand and develop their businesses.

  • I can't see how a mature agile team requires any *management*?

    - by ashy_32bit
    After a recent heated debate over Scrum, I realized my problem is that I think of management as a quite unnecessary and redundant activity in a fully agile team. I believe a mature Agile team does not require management or any non-technical decision making process of whatsoever. To my (apparently erring) eyes it is more than obvious that the only one suitable and capable of managing a mature development team is their coach (and that being the most technically competent colleague with proper communication skills). I can't imagine how a Scrum master can contribute to such a team. I am having a great difficulty realizing and understanding the value of such things as Scrum and manager as someone who is not a veteran developer but is well skilled in planning the production cycles when a coach exists in the team. What does that even mean? How on earth someone with no edge-skills of development can manage a highly technical team? Perhaps management here means something else? I see management as a total waste of time and a by-product of immaturity. In my understanding a mature team is fully self-managing. Apparently I'm mistaken since many great people say the contrary but I can't convince myself.

  • Whys is System process listening on Port 80?

    - by Seth Spearman
    I am running Windows 7 RC1. I have multiple issues getting IIS to work on my system and today when I installed a new application and I tried to load it using http:\localhost\MyApplication I get absolutely no errors and I get no page load. Just a pretty, white blank page. I did some digging and I found something about some other process listening on port 80 so I did a scan using netstat -aon | findstr 0.0:80 and discovered that PID 4 was listening on that port. PID 4 does not show in task manager so I fired up Process Explorer and it showed me that PID 4 is the System process. (Multiple google searches seems to indicate that System always uses PID 4). Since then I am basically stuck. I have no idea why System needs port 80 and what to do about it. If you google the following strings you will find two helpful Experts-Exchange articles at the top of the search results and you can read them for some helpful information. (If I gave the direct URL to the pages then Experts-Exchange would ask you to pay...but when you click on the results from a google search you can scroll all of the way to the bottom to read the exchanges.) Here are the google searches... "System Process is listening on port 80 (Vista)" "SYSTEM Process is listening on Port 80 and Preventing IIS Default Website from Running" The last entry from the first result showed how to do a trace of http.sys at the following URL: http://blogs.msdn.com/wndp/archive/2007/01/18/event-tracing-in-http-sys-part-1-capturing-a-trace.aspx Trace showed nothing useful. Any thoughts?

  • How to remove NTFS system files from a previous Vista installation

    - by Boldewyn
    I'm trying to shrink my system partition under Win Vista. It's all fine, except that in front of the last 300MB of the volume sits a single file, that cannot be moved by defrag or other means from its position. It's called C:\$Extend\$UsnJrnl:$J, and my assumtion is, that it is left from a previous installation of Vista, when I re-set up the system. Now, googling for this kind of files brings interesting results, but no solution to my problem: Files left on the disk can become ownerless in a new setup of Windows and inaccessible (even for administrators). To be able to access them again, I found the tip to use takeown to re-assign them to the Admin group (or anyone else). Works like a charm for normal files, but not for the C:\$Extend stuff. The C:\$Extend folder is a system folder of the NTFS file system, where the journal is stored (especially in a file called $UsnJrnl:$Data, whose name is surprisingly close to mine). You can delete the journal with fsutil usn /delete C:, however, this doesn't work from within the booted system (as I found out trying). Also, I'm not quite sure of the side effects. You can't move the NTFS own files with standard defrag tools. The same holds, by the way, for not accessible files. Every bit of knowledge out there is targeted to either not accessible files or the $Extend NTFS stuff, but noone addresses my problem involving both, an inaccessible system file. Question: How can I remove this file, or at least how can I move it on the disk?

  • Efficiently separating Read/Compute/Write steps for concurrent processing of entities in Entity/Component systems

    - by TravisG
    Setup I have an entity-component architecture where Entities can have a set of attributes (which are pure data with no behavior) and there exist systems that run the entity logic which act on that data. Essentially, in somewhat pseudo-code: Entity { id; map<id_type, Attribute> attributes; } System { update(); vector<Entity> entities; } A system that just moves along all entities at a constant rate might be MovementSystem extends System { update() { for each entity in entities position = entity.attributes["position"]; position += vec3(1,1,1); } } Essentially, I'm trying to parallelise update() as efficiently as possible. This can be done by running entire systems in parallel, or by giving each update() of one system a couple of components so different threads can execute the update of the same system, but for a different subset of entities registered with that system. Problem In reality, these systems sometimes require that entities interact(/read/write data from/to) each other, sometimes within the same system (e.g. an AI system that reads state from other entities surrounding the current processed entity), but sometimes between different systems that depend on each other (i.e. a movement system that requires data from a system that processes user input). Now, when trying to parallelize the update phases of entity/component systems, the phases in which data (components/attributes) from Entities are read and used to compute something, and the phase where the modified data is written back to entities need to be separated in order to avoid data races. Otherwise the only way (not taking into account just "critical section"ing everything) to avoid them is to serialize parts of the update process that depend on other parts. This seems ugly. To me it would seem more elegant to be able to (ideally) have all processing running in parallel, where a system may read data from all entities as it wishes, but doesn't write modifications to that data back until some later point. The fact that this is even possible is based on the assumption that modification write-backs are usually very small in complexity, and don't require much performance, whereas computations are very expensive (relatively). So the overhead added by a delayed-write phase might be evened out by more efficient updating of entities (by having threads work more % of the time instead of waiting). A concrete example of this might be a system that updates physics. The system needs to both read and write a lot of data to and from entities. Optimally, there would be a system in place where all available threads update a subset of all entities registered with the physics system. In the case of the physics system this isn't trivially possible because of race conditions. So without a workaround, we would have to find other systems to run in parallel (which don't modify the same data as the physics system), other wise the remaining threads are waiting and wasting time. However, that has disadvantages Practically, the L3 cache is pretty much always better utilized when updating a large system with multiple threads, as opposed to multiple systems at once, which all act on different sets of data. Finding and assembling other systems to run in parallel can be extremely time consuming to design well enough to optimize performance. Sometimes, it might even not be possible at all because a system just depends on data that is touched by all other systems. Solution? In my thinking, a possible solution would be a system where reading/updating and writing of data is separated, so that in one expensive phase, systems only read data and compute what they need to compute, and then in a separate, performance-wise cheap, write phase, attributes of entities that needed to be modified are finally written back to the entities. The Question How might such a system be implemented to achieve optimal performance, as well as making programmer life easier? What are the implementation details of such a system and what might have to be changed in the existing EC-architecture to accommodate this solution?

  • Mixing Silverlight-Specific System.Xml.Linq dll with Non-Silverlight System.Xml.Linq dll

    - by programatique
    I have a Logic layer that references Silverlight's System.Xml.Linq dll and a GUI that is in WPF (hence using the non-Silverlight System.Xml.Linq dll). When I attempt to pass an XElement from GUI project to a method in the Logic project, I am getting (basically) "XElement is not of type XElement" errors. To complicate matter, I am unable to edit the Logic layer project. The Non-Silverlight DLL is at: C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.5\System.Xml.Linq.dll THe Silverlight DLL is at: C:\Program Files (x86)\Microsoft SDKs\Silverlight\v3.0\Libraries\Client\System.Xml.Linq.dll I am new to C# but I'm fairly sure my issue is that I am referencing different DLL's to access the System.Xml.Linq namespace. I attempted to replace my non-Silverlight System.Xml.Linq.dll with the Silverlight's System.Xml.Linq.dll, but received assembly errors. Is there any way to resolve this short of scrapping my WPF GUI project and creating a Silverlight project?

  • Why is there only one configuration management tool in the main repository?

    - by David
    How is it that Cfengine does not exist in the Ubuntu (10.04 LTS) Main Repository? I can't find a discussion of this anywhere (using Google). The only configuration management in Ubuntu Main seems to be Puppet. I looked for a wide variety of others as well - all from Wikipedia's list of configuration management tools - and none of them are present in Ubuntu main. I looked for bcfg2, opensymbolic, radmind, smartfrog, spacewalk, staf, synctool, chef - none are present. From my vantage point as a system administrator, I would have expected to find at least bcfg2, puppet, cfengine, and chef (as the most widely used tools). Why is cfengine (or chef and others) not included in Ubuntu main? Why is there only one configuration management tool in Ubuntu main? By the way - the reason this is important in the context of server administration is because Ubuntu main is fully supported by the Ubuntu team with updates and security updates; the other repositories are not.
