  • The MDM Journey: From the Customer Perspective

    - by Mala Narasimharajan
    Master Data Management is more than just about a single version of  the truth or providing a 360 degree view of the customer.  It spans multiple domains ranging from customers to suppliers to products and beyond.  MDM is pivotal to providing a solid customer experience - one that results in repeat business, continued loyalty and last but not least - high customer satisfaction.  Customer experience is not only defined as accurate information about the customer for the enterprise, but also presenting the customer with the right information about products, orders, product availability, etc.   Let's take a look at a couple of customer use cases with Oracle MDM. Below is a picture from a recent customer panel: Oracle MDM is a key platform for increasing upsell/cross-sell opportunities, improve targeting of customers and uncover new sales opportunies, reduce inaccuracies in mailing marketing materials to prospects, as well as to tap into and uncover the full value of a customer across business units more accurately.  A leading investment and private bank leverages Oracle MDM to do a better job of identifying clients, their levels of investment as well as consistently manage them through a series of areas such as credit, risk, new accounts, etc. Ultimately, they are looking to understand client investments and touchpoints across the company's offerings.  Another use case for Oracle MDM is with a major financial and insurance services company with clients worldwide, looking to resolve customer data inaccuracies and client information stored differently across mulitiple systems.  For more information on Oracle Master Data Management, click here.

  • Process Improvement and the Data Professional

    - by BuckWoody
    Don’t be afraid of that title – I’m not talking about Six Sigma or anything super-formal here. In many organizations, there are more folks in other IT roles than in the Data Professional area. In other words, there are more developers, system administrators and so on than there are the “DBA” role. That means we often have more to do than the time we need to do it. And, oddly enough, the first thing that is sacrificed is process improvement – the little things we need to do to make the day go faster in the first place. Then we get even more behind, the work piles up and…well, you know all about that. Earlier I challenged you to find 10-30 minutes a day to study. Some folks wrote back and asked “where do I start”? Well, why not be super-efficient and combine that time with learning how to make yourself more efficient? Try out a new scripting language, learn a new tool that automates things or find out ways others have automated their systems. In general, find out what you’re doing and how, and then see if that can be improved. It’s kind of like doing a performance tuning gig on yourself! If you’re pressed for time, look for bite-sized articles (like the ones I’ve done here for PowerShell and SQL Server) that you can follow in a “serial” fashion. In a short time you’ll have a new set of knowledge you can use to make your day faster. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • 12.04 WiFi issue on a particular access point

    - by user71706
    I have a WiFi access point that I connect to a PC to share its Internet connection with multiple machines, in a training environment. All the machines with 11.04 connect to this access point with no problem, and can access any server on the Internet. These machines have an Intel Wireless -N 1030 BGN chipset (as reported by lspci). Now, my problem is that I don't manage to connect 12.04 machines to this wireless network. The systems I tried do manage to connect (confirmed by Network Manager), but when I try to access a website like http://kernel.org, the browser shows "Connecting to kernel.org...", but displays a "The connection has timed out" error page. Other symptoms: Name resolution works (for example 'nslookup kernel.org') finds kernel.org's IP address 'ping kernel.org' doesn't work The same 12.04 machines have no problem at all with other wireless networks. So there is probably something weird in my access point (though the 11.04 machines are not impacted). Would you have any suggestions for investigating this issue? Thanks, Michael.

  • Use C2WTS to get a classic windows identity from a claims identity

    - by Sahil Malik
    SharePoint, WCF and Azure Trainings: more information I know you’re going to find this useful at some point. A lot of backend systems still demand classic windows identities, but everything we do now has moved to claims. So sometimes (albeit rare), we have to translate a claims identity into a classic windows identity. This is where the “Claims to Windows Token Service” comes into play. SharePoint 2010 and 2013 make use of this but you can use this in any .NET application. First of all, there are some basic requirements for this to work, First, you will need the string value of a UPN claim. Just a string value, really! This means you can also use FBA or anything else. The “proper” way to do this of course is that you must originate this from a AD backed claim. So a user authenticated using ADFS or similar would be perfect. Just remember that you must issue the UPN claim. Read full article ....

  • Sys Admins are kind of like gods, aren't they? [closed]

    - by user75798
    A systems administrator has root access to the entire system. There is nothing they cannot do. They are omnipotent. Their power is absolute. Nothing dan stand before them. Like Sauron, the Dark Lord, they do not share power. There can be but one root. Else contradiction at the most fundamental level is possible, and that can not be tolerated. The sys admin's power is unconditional and non-negotiable. To be a sys admin is like being a god. (And if they are a god, what is the religion?) There is an old saying that absolute power corrupts absolutely. I wonder whether being a sys admin has ended up warping an individual. Perhaps a sys admin has become crazed or even gone berserk? Surely sys admins must need to be very level headed people. For example, imagine being 'the' sys admin for the NSA. (What an awesome job that would be!) Think about the access to data, the encryption keys, the secrets... Perhaps one day a sys admin might go bonkers, turn up for work and 'uninstall the entire NSA'! :) But you would have the same sorts of responsibilities working at a bank or other organization. I wonder whether much emphasis is put on ensuring that sys admins are level headed in the first place and kept sweet in the second. Do they get paid well? I am sure they do not receive half of what they are worth, considering all the hard earned knowledge they have had to gain and the massive responsibility they have.

  • How can I triple boot Xubuntu, Ubuntu and Windows?

    - by ag.restringere
    Triple Booting Xubuntu, Ubuntu and Windows I'm an avid Xubuntu (Ubuntu + XFCE) user but I also dual boot with Windows XP. I originally created 3 partitions and wanted to use the empty one as a storage volume but now I want to install Ubuntu 12.04 LTS (the one with Unity) to do advanced testing and packaging. Ideally I would love to keep these two totally separate as I had problems in the past with conflicts between Unity and XFCE. This way I could wipe the Ubuntu w/ Unity installation if there are problems and really mess around with it. My disk looks like this: /dev/sda1 -- Windows XP /dev/sda2 -- Disk /dev/sda: 200.0 GB, 200049647616 bytes 255 heads, 63 sectors/track, 24321 cylinders, total 390721968 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Device Boot Start End Blocks Id System /dev/sda1 * 63 78139454 39069696 7 HPFS/NTFS/exFAT /dev/sda2 78141440 156280831 39069696 83 Linux /dev/sda3 156282878 386533375 115125249 5 Extended /dev/sda4 386533376 390721535 2094080 82 Linux swap / Solaris /dev/sda5 156282880 386533375 115125248 83 Linux Keep each in it's own partition and totally separate and be able to select from each of the three systems from the GRUB boot menu... sda1 --- [Windows XP] sda2 --- [Ubuntu 12.04] "Unity" sda3(4,5) -- [Xubuntu 12.02] "Primary XFCE" What is the safest and easiest way to do this without messing my system up and requiring invasive activity?

  • Microsoft releases Visual Studio 2010 SP1

    - by brian_ritchie
    Microsoft has been beta testing SP1 since December of last year.  Today, it was released to MSDN subscribers and will be available for public download on March 10, 2011.The service pack includes a slew of fixes, and a number of new features: Silverlight 4 supportBasic Unit Testing support for the .NET Framework 3.5Performance Wizard for SilverlightIntelliTrace for 64-bit and SharePointIIS Express supportSQL CE 4 supportRazor supportHTML5 and CSS3 support (IntelliSense and validation)WCF RIA Services V1 SP1 includedVisual Basic Runtime embeddingALM Improvements Of all the improvements, IIS Express probably has the largest impact on web developer productivity.  According to Scott Gu, it provides the following:It’s lightweight and easy to install (less than 10Mb download and a super quick install)It does not require an administrator account to run/debug applications from Visual Studio It enables a full web-server feature set – including SSL, URL Rewrite, Media Support, and all other IIS 7.x modules It supports and enables the same extensibility model and web.config file settings that IIS 7.x support It can be installed side-by-side with the full IIS web server as well as the ASP.NET Development Server (they do not conflict at all) It works on Windows XP and higher operating systems – giving you a full IIS 7.x developer feature-set on all OS platforms IIS Express (like the ASP.NET Development Server) can be quickly launched to run a site from a directory on disk.  It does not require any registration/configuration steps. This makes it really easy to launch and run for development scenarios.Good stuff indeed.  This will make our lives much easier.  Thanks Microsoft...we're feeling the love!

  • Dual monitor setup can cause boot problem?

    - by kriszpontaz
    I have a two monitor setup, one 22" (1680x1050 res., 16:10) and another 19" (1280x1024 res. 5:4). I've installed ubuntu 11.10 beta2 x86, and the installation worked fine, the system boot was successful. I've upgraded ubuntu from the main server, and after restart, booting with the kernel 3.0.0-13, my system hangs up with a purple screen, and than nothing happens (the system boots successful with the kernel image 3.0.0-8). Nvidia current drivers not installed, but if i install it, the situation is the same. I have an Nvidia 9600GT installed. I tried to boot with one screen attached, I've tried each port, but no luck at all. With kernel image 3.0.0-8 the system successfully boots with each display attached, but the farther kernels (3.0.0-11; 3.0.0-12; ect.) all freezes, even one display, or multiple attached. I have two systems with ubuntu installed, and the other (with Ati HD 2400XT, latest closed drivers) don't have any issues like this, I wrote about. Update: The problem solved by reinstalling the operatin system, without automatically installing updates during install, with only one monitor attached. After completing installation, and clean reboot, i've installed closed nVidia drivers. After all, i found it's safe to connect another monitor to the system, it's not causing any problems. Probably the situation stays like this.

  • Weird system freeze. Nothing works keyboard/mouse/reset button - Ubuntu 12.04 64bits [closed]

    - by Simon
    I have fresh PC: i5 3570K with Intel 4000 onboard ASrock Z77 Extreme4-m 8GG RAM - Adata 1333Mhz... 1TB Seagate drive 7200rpm I've also fresh systems - Ubuntu/Win7 and today there was something strange. Ubuntu twice just freezed. Everything stopped, even keyboard and mouse wasn't responding. Even RESET button didn't work. Right now memtest is running, but I'd like to know, where else can i look for cause. Can it be software fault if even reset isn't working? Only long reset pressing rebooted PC... I'm a bit confused. Or should I test components - CPU, motherboard, disk. Which logs in Ubuntu should I check to diagnose cause? EHm I had few adventures with this PC already. Shipped motherboard was broken (ASrock Z68 Extreme3) and had old bios, so I had to contact with reseller, replace it and at the end decided on Z77, but everything took 3 weeks, so I have bad feelings... Edit: Both freezes were during editing something in gedit (it can be coincidence) and after few updates today - when memtest is end I'll check what was updated

  • Releasing software/Using Continuous Integration - What do most companies seem to use?

    - by Sagar
    I've set up our continuous integration system, and it has been working for about a year now. We have finally reached a point where we want to do releases using the same. Before our CI system, the process(es) that was used was: (Develop) -> Ready for release -> Create a branch -> (Build -> Fix bugs as QA finds them) Loop -> Final build -> Tag (Develop) -> Ready for release -> (build -> fix bugs) Loop -> Tag Our CI setup: 1 server for development (DEV) 1 server for qa/release (QA) The second one has integrated into CI perfectly. I create a branch when the software is ready for release, and the branch never changes thereafter, which means the build is reproduceable without having to change the CI job. Any future development takes place on HEAD, and even maintainence releases get a completely new branch and a completely new job, which remains on the CI system forever, and then some. The first method is harder to adapt. If the branch changes, the build is not reproduceable unless I use the tag to build [jobs on the CI server uses the branch for QA/RELEASE, and HEAD for development builds]. However, if I use the tag to build, I have to create a new CI job to build from the tag (lose changelog on server), or change the existing job (lose original job configuration). I know this sounds complicated, and if required, I will rewrite/edit to explain the situation better. However, my question: [If at all] what process does your company use to release software using continuous integration systems. Is it even done using the CI system, or manually?

  • Back to Sony

    - by Bunch
    Well I switched back to Sony. After about a year of debating whether or not to keep my XBox 360 or get a PS3 I decided over the weekend to trade in the 360 for a PS3.  I had thought about keeping both but I really don’t need two gaming systems. So far I like it, the graphics are good and the game selection is pretty much the same. For me the game exclusives didn’t sway me one way or the other (i.e. I’ve never played Halo so you can’t miss what you never played). My main reasons for switching were: RROD – I’ve had three and I don’t play a huge amount per week. Free online gaming – I never did buy a Live Gold account even though it is affordable Blu-ray player – Figured this is as good of a time as any to finally get one Netflix streaming with no need for an upgrade to your online account like on XBox MUCH quieter system Finally at a $299 price point All in all the last point was the main one for me. Like a lot of other folks I was really put off by the PS3’s original pricing of $499 and $599. Technorati Tags: Gaming

  • Facebook shared links not opening (Redirecting correctly) [on hold]

    - by Hammad
    I have been in a problem and after hours of searching find nothing useful to counter it. I have a website, and that website has RSS feed attached to facebook page. As I post the content to website it also appears on facebook page. But I have people complaining on my page that my posts don't open when they click the link to read the details. Since I am a Chrome user and didn't notice this happening for months. But as I checked it through firefox and Internet Explorer, I found the links shared actually don't open with these browswers. They only work in Chrome, means they are properly redirected in chrome browser and not in firefox and IE. Whenever I click on links of posts on my page through IE or firefox the url does not simply redirect to my website and I get to see nothing as if I am not connecting to Internet. When examining URL I see this: http://www.facebook.com/l.php?u=http%3A%2F%2Fbit.ly%2F112NVO9&h=EAQHDgTUv&s=1 Which shows that facebook is not redirecting the links properly. Moreover I also use link shortening service bit.ly to shorten my shared links. I have checked same problem exists even if I don't shorten my links. And I checked I am not alone, even the tech giant website mashable.com links also don't open in IE and FF from facebook, they only open in Chrome. From mobile phone the links don't open (redirected properly) even in chrome. Can anyone tell me what is the issue? Nothing much is written about it on Internet as no once has faced this problem. P.S: I have checked from different systems, the problem persists.

  • State changes in entities or components

    - by GriffinHeart
    I'm having some trouble figuring how to deal with state management in my entities. I don't have trouble with Game state management, like pause and menus, since these are not handled as an entity component system; just with state in entities/components. Drawing from Orcs Must Die as an example, I have my MainCharacter and Trap entities which only have their components like PositionComponent, RenderComponent, PhysicsComponent. On each update the Entity will call update on its components. I also have a generic EventManager with listeners for different event types. Now I need to be able to place the traps: first select the trap and trap position then place the trap. When placing a trap it should appear in front of the MainCharacter, rendered in a different way and following it around. When placed it should just respond to collisions and be rendered in the normal way. How is this usually handled in component based systems? (This example is specific but can help figure out the general way to deal with entities states.)

  • Why is purchasing Microsoft licences such a daunting task? [closed]

    - by John Nevermore
    I've spent 2 frustrating days jumping through hoops and browsing through different local e-shops for VS (Visual Studio) 2010 Pro. And WHS (Windows Home Server) FPP 2011 licenses. I found jack .. - or to be more precise, the closest I found in my country was WHS OEM 2011 licenses after multiple emails sent to individuals found on Microsoft partners page. Question being, why is it so difficult to get your hands on Microsoft licenses as an individual? Sure, you can get the latest end user operating systems from most shops, but when it comes to development tools or server software you are left dry. And companies that do sell licenses most of the time don't even put up pricing or a self service environment for buying the licenses, you need to have an hawk's eye for that shiny little Microsoft partner logo and spam through bunch of emails not knowing, if you can count on them to get the license or not. Sure, i could whip out my credit card and buy the VS 2010 license on the online Microsoft Shop. Well whippideegoddamndoo, they sell that, but they don't sell WHS 11 licenses. Why does a company make it so hard to buy their products? Let's not even talk about the licensing itself being a pain.

  • Strategy for hosting 700+ domains, each with static HTML site

    - by jonschlinkert
    I have a portfolio of more than 700 domain names, and ideally I'd like to put up a single-page HTML/CSS/JavaScript webpage for each domain. Is there a system/strategy/workflow that will allow me to: Automate the deployment of new websites, quickly and easily without having to manually initiate each new website in an admin panel. For instance, I've seen dropbox-based solutions that claim to make it simple to setup new websites on your dropbox account, but you still have to set each one up in an admin interface first. It would be so much easier to have a folder naming convention that allowed the user to easily clone/copy/duplicate sites inside their Dropbox App folder (https://www.dropbox.com/developers/blog/23) to create new ones. Sounds interesting, however... It's easy to managing CNAMEs on the registrar-side, is there a way to quickly associate CNAMEs with new websites, maybe gh-pages-style (https://help.github.com/articles/setting-up-a-custom-domain-with-pages)? With GitHub's gh-pages, all you have to do is drop a file called CNAME into your repo, with the domain name you want associated with the repo inside the file. gh-pages isn't a good solution for what I'm doing though unfortunately. I'm also a front-end developer, specializing in rapid web development and "front-end build systems", so I building and maintaining static assets for hundreds of sites is no problem. It's the hosting-side that I really struggle with. Any suggestions?

  • Ranking players depending on decision making during a game

    - by tabchas
    How would I go about a ranking system for players that play a game? Basically, looking at video games, players throughout the game make critical decisions that ultimately impact the end game result. Is there a way or how would I go about a way to translate some of those factors (leveling up certain skills, purchasing certain items, etc.) into something like a curve that can be plotted on a graph? This game that I would like to implement this is League of Legends. Example: Player is Level 1 in the beginning. Gets a kill very early in the game (he gets gold because of the kill and it increases his "power curve"), and purchases attack damage (gives him more damage which also increases his "power curve". However, the player that he killed (Player 2), buys armor (counters attack damage). This slightly increases Player 2's own power curve, and reduces Player 1's power curve. There's many factors I would like to take into account. These relative factors (example: BECAUSE Player 2 built armor, and I am mainly attack damage, it lowers my OWN power curve) seem the hardest to implement. My question is this: Is there a certain way to approach this task? Are there similar theoretical concepts behind ranking systems that I should read up on? I've seen the ELO system, but it doesn't seem what I want since it simply takes into account wins and losses.

  • How does datomic handle "corrections"?

    - by blueberryfields
    tl;dr Rich Hickey describes datomic as a system which implicitly deals with timestamps associated with data storage from my experience, data is often imperfectly stored in systems, and on many occasions needs to retroactively be corrected (ie, often the question of "was a True on Tuesday at 12:00pm?" will have an incorrect answer stored in the database) This seems like a spot where the abstractions behind datomic might break - do they? If they don't, how does the system handle such corrections? Rich Hickey, in several of his talks, justifies the creation of datomic, and explains its benefits. His work, if I understand correctly, is motivated by core the insight that humans, when speaking about data and facts, implicitly associate some of the related context into their work(a date-time). By pushing the work required to manage the implicit date-time component of context into the database, he's created a system which is both much easier to understand, and much easier to program. This turns out to be relevant to most database programmers in practice - his work saves everyone a lot of time managing complex, hard to produce/debug/fix, time queries. However, especially in large databases, data is often damaged/incorrect (maybe it was not input correctly, maybe it eroded over time, etc...). While most database updates are insertions of new facts, and should indeed be treated that way, a non-trivial subset of the work required to manage time-queries has to do with retroactive updates. I have yet to see any documentation which explains how such corrections, or retroactive updates, are handled by datomic; from my experience, they are a non-trivial (and incredibly difficult to deal with) subset of time-related data manipulation that database programmers are faced with. Does datomic gracefully handle such updates? If so, how?

  • Why did the web win the space of remote applications and X not?

    - by Martin Josefsson
    The X Window System is 25 years old, it had it's birthday yesterday (on the 15'th). As you probably are aware of, one of it's most important features is the separation of the server side and the client side in a way that neither Microsoft's, Apples or Wayland's windowing systems have. Back in the days (sorry for the ambiguous phrasing) many believed X would dominate over other ways to make windows because of this separation of server and client, allowing the application to be ran on a server somewhere else while the user clicks and types on her own computer at home. This use obviously still exists, but is marginalized at best. When we write and use programs that run on a server we almost always use the web with it's html/css/js. Why did the web win, and X not? The technologies used for the web (said html/css/js) are a mess. Combined with all the back-end-frameworks (Rails, Django and all) it really is a jungle to navigate thru. Still the web thrives with creativity and progress, while remote X apps do not.

  • Cleaning Up After Chrome

    - by Mark Treadwell
    I find Google Chrome, which I have no interest in, is continually getting installed on machines in my house, mostly due to Adobe Shockwave bringing it along as an install package. (Family members are agreeing to the download, not realizing the Chrome is getting dropped as well.) My major issue after uninstalling Chrome is that you can no longer click on links in Outlook emails. There is a lot on the web about this, and Google has not been proactive at fixing their uninstaller. I have now added a registry file to my Win64 systems to reset the problem registry keys and clear the error. This registry file is pretty simple. It merely resets HKEY_CURRENT_USER\Software\Classes\.htm, HKEY_CURRENT_USER\Software\Classes\.html, and HKEY_CURRENT_USER\Software\Classes\.shtml back to their default values of "htmlfile". Chrome takes over the handling of these file extensions because its default install is to make itself the default web browser. The Chrome uninstalled fails to clear/reset them. In troubleshooting this, I looked in my registry based on the web info on the Chrome uninstall problem. Since my system had never had Chrome installed, my registry did not have the problem keys. To troubleshoot, I installed (ugh!) and uninstalled Chrome. Sure enough, Chrome left the expected debris with a value string of "ChromeHTML.PR2EPLWMBQZK3BY7Z2BFBMFERU" or something similar. Resetting these values fixed the problem. I see that Chrome leaves quite a bit of debris behind in the registry. I guess it is creating the keys then leaving them behind, even though their presence (with bad data) subsequently affects operations.

  • Desktop goes un-usable after upgrade to 12.04

    - by Tom Nail
    I have multiple Ubuntu systems connected to a KVM, one of which I recently upgraded from Ubuntu 10 to 12.04. After the upgrade, this system desktop does fine until it is allowed to go to idle (i.e., I've switched to another system on the KVM and it locks it's desktop). When I come back to it, the screen is garbled and paging across at a rate seemingly determined by the mouse. Although no pointer is visible, I can get the screen to stop paging (and just be garbled) by moving the mouse left and right. The paging will slow down and come to a stop, if I can align things carefully enough. This condition persists even when I try to go to a CLI-based login (e.g., CTRL+Alt+F1) and will continue until I reboot the machine. Unfortunately, I'm not very familiar with the Unity desktop, so I don't know where to find things to troubleshoot. A restart of lightdm doesn't change anything, so I'm wondering if this might be more hardware based( although this machine hasn't given me any trouble previously in the same setup). The .xsession-errors file has some issues with compiz, nautilus and GConf listed, but I'm not sure those are actually germane to the issue. Thanks for any help, -=Tom
