• Three Master Data Management Deployment Tips

  - by david.butler(at)oracle.com

  MDM is all about data quality and data governance. We now know that improved data quality raises all operational and analytical boats. But it's not just about deploying data quality tools. It's about deploying data quality tools within and across the IT landscape - from a thousand points of data entry to a single version of the truth. Here are three tips to deploying MDM across your applications and enterprise.   #1: Identify a tactical, high-value business problem where MDM can materially help. §  Support a customer acquisition and retention program with a 'customer' master data solution. §  Accelerate new products and services to market with a 'product' master data solution. §  Reduce supplier exceptions or support spend control initiatives with a 'supplier' master data solution. §  Support new store (branch, campus, restaurant, hospital, office, well head) location analysis with a 'site' master data solution. §  Fix long standing Chart of Accounts and Cost Center problems with a 'financial' master data solution. §  Support M&A activity, application upgrades, an SOA initiative, a cloud computing program, or a new business intelligence deployment by implementing a mix of master data solutions.   #2: Incrementally expand to a full information architecture. Quite often, the measurable return on interest from tactical MDM initiatives will fund future deployments. Over time, the MDM solution expands into its full architecture to cover the entire IT landscape. Operations and analytics are united, IT flexibility is restored, and sustainable competitive advantage is achieved.   #3: Bring business into every MDM deployment. To be successful, MDM must work hand in hand with data governance. In fact, Oracle MDM incorporates data governance tools for business users. IT can insure data quality, but only after the business side has defined what quality means. The business establishes the rules for governing the master data, and then IT enforces the rules via the MDM applications. Without this business/IT collaboration, MDM initiatives seldom achieve their full potential.   It is not very often that a technology comes along that can measurably assist organizations across a wide variety of top IT initiatives. Reducing costs, increasing flexibility, getting more out of existing assets, and aligning business and IT are not easy tasks for any CIO. But with MDM, success is achievable. IT can regain its place as a center for innovation.   For more information on this topic, take a look at my article Master Data Management Deployment Tips in the Opinion Section of Oracle's Profit Online magazine.

• Best way to render card images

  - by user1065145

  I have high-quality SVG card images, but they drastically lose their quality when I downsize them. I have tried two ways of rendering cards (using Inkscape and Imagemagics): 1) Render SVG to high-res PNG and resize it then; 2) Render SVG to image of proper size at once. Both approaches generate blurry card images, which looks even worse than old Windows cards. What are the best way to generate smaller card images from SVG sources and not to loose their quality a lot?

• Decrease filesize when resizing with mogrify

  - by plua

  I love the command line options of imagemagick. Mogrify is great to resize images and change quality, which is what I use most often. However, I have noted that the filesize if often larger than what it should be. Especially with small images. For instance, I have a regular 640px (width) photo, which I change to quality 80 and a width of 80px: mogrify -quality 80 -resize 80 file.jpg Works well and my image gets resized and the quality is changed to 80. However, the filesize is around 40Kb. For such a tiny image, that is huge! When I use mtPaint, and open the file and save it (not changing anything, just CTRL+O, CTRL+S), the filesize decreases with more than 95% to less than 2Kb! I have seen this is often the case. What goes wrong?

• Does the Adblock Plus extension prevent malicious code from downloading/executing? [closed]

  - by nctrnl

  Firefox and Chrome are my favourite browsers. The main reason is an extension called Adblock Plus. Basically, it blocks all the ad networks if you subscribe to one of the lists, like EasyList. Does it also protect against malicious ads on completely legitimate websites? For instance, several news websites use ad services that may allow a malicious user to insert "evil code". This makes the web very unsafe, especially for those who lack a serious antivirus product.

• Proactively using 'lines of code' (LOC) metric in your software-development process?

  - by manuel aldana

  hi there, I find the LOC (lines of code) metric a simple but nice metric to get an overview of software codebase complexity (see also blog-entry 'implications of lines-of-code'). I wondered how many of you out there are using this metric as a centric part for retrospective (for removing unused functionality or dead code). I think creating awareness that more lines-of-code mean more complexity in maintenance and extension is valuable.

• What to do when opensource project starts to tear apart? (or a manager tries to write code and than shouts at the team)

  - by Kabumbus

  Imagine there is an open source cross-platform project on Google code. It has lots of revisions (1000). It concentrates in itself lots technological stuff - rare stuff - it mixes top tech. It contains server, and more than one client. The project was created by a well-connected team of developers (friends) and a manager that was sponsoring project at its start up during its first few months (project now is more than a year old-sponsoring oss project is a big good deal- also gave the idea of project to developers). The project was growing in complexity and effort reqiered to continue development. Once upon a time a manager - team leader started trying to write code (he was a programmer in some other projects - not the best, but he felt like he was one). He started because one of the developers suggested an idea at the team meeting and he felt he just needed to do it on his own. He failed, and he told the dev team about it. The dev team did what he failed to do in a few days. After that, the manager feels that team codes with out him perfectly and gets the job done in short time. He felt sorry and lost and he started to crash like an old bad PC. Firstly, he started to scream (in forms of messages not in voice) he tried to tell developers that what they were doing was a bad, not-needed thing - developers kindly told him that his "beginnings" were not compilable while dev team product worked as needed. He told the developers that all work they do should be firstly discussed with him. Here is the part where we need to mention that all team members are "project owners" and logically have equal rights. The team leader suggested to the developers these options: change their dev process to go through him, or be moved from project owners to contributers. So what are our options as developers? What arguments we can provide to the team leader/manager for him to calm down? Is it possible to save the project or is it better to fork out now? An important issue is that lately we had no active ticket system, and I personally think that this was the reason the mess appeared. So... any ideas?

• Why Does Adding a UDF or Code Truncates the # of Resources in List?

  - by Jeffrey McDaniel

  Go to the Primavera - Resource Assignment History subject area.  Go under Resources, General and add fields Resource Id, Resource Name and Current Flag. Because this is using a historical subject area with Type II slowly changing dimensions for Resources you may get multiple rows for each resource if there have been any changes on the resource.  You may see a few records with current flags = 0, and you will see a row with current flag = 1 for all resources. Current flag = 1 represents this is the most up to date row for this resource.  In this query the OBI server is only querying the W_RESOURCE_HD dimension.  (Query from nqquery log) select distinct 0 as c1,      D1.c1 as c2,      D1.c2 as c3,      D1.c3 as c4 from       (select distinct T10745.CURRENT_FLAG as c1,                T10745.RESOURCE_ID as c2,                T10745.RESOURCE_NAME as c3           from                 W_RESOURCE_HD T10745 /* Dim_W_RESOURCE_HD_Resource */            where  ( T10745.LAST_RUN_PER_DAY_FLAG = 1 )       ) D1 If you add a resource code to the query now it is forcing the OBI server to include data from W_RESOURCE_HD, W_CODES_RESOURCE_HD, as well as W_ASSIGNMENT_SPREAD_HF. Because the Resource and Resource Codes are in different dimensions they must be joined through a common fact table. So if at anytime you are pulling data from different dimensions it will ALWAYS pass through the fact table in that subject areas. One rule is if there is no fact value related to that dimensional data then nothing will show. In this case if you have a list of 100 resources when you query just Resource Id, Resource Name and Current Flag but when you add a Resource Code the list drops to 60 it could be because those resources exist at a dictionary level but are not assigned to any activities and therefore have no facts. As discussed in a previous blog, its all about the facts.   Here is a look at the query returned from the OBI server when trying to query Resource Id, Resource Name, Current Flag and a Resource Code.  You'll see in the query there is an actual fact included (AT_COMPLETION_UNITS) even though it is never returned when viewing the data through the Analysis. select distinct 0 as c1,      D1.c2 as c2,      D1.c3 as c3,      D1.c4 as c4,      D1.c5 as c5,      D1.c1 as c6 from       (select sum(T10754.AT_COMPLETION_UNITS) as c1,                T10706.CODE_VALUE_02 as c2,                T10745.CURRENT_FLAG as c3,                T10745.RESOURCE_ID as c4,                T10745.RESOURCE_NAME as c5           from                 W_RESOURCE_HD T10745 /* Dim_W_RESOURCE_HD_Resource */ ,                W_CODES_RESOURCE_HD T10706 /* Dim_W_CODES_RESOURCE_HD_Resource_Codes_HD */ ,                W_ASSIGNMENT_SPREAD_HF T10754 /* Fact_W_ASSIGNMENT_SPREAD_HF_Assignment_Spread */            where  ( T10706.RESOURCE_OBJECT_ID = T10754.RESOURCE_OBJECT_ID and T10706.LAST_RUN_PER_DAY_FLAG = 1 and T10745.ROW_WID = T10754.RESOURCE_WID and T10745.LAST_RUN_PER_DAY_FLAG = 1 and T10754.LAST_RUN_PER_DAY_FLAG = 1 )            group by T10706.CODE_VALUE_02, T10745.RESOURCE_ID, T10745.RESOURCE_NAME, T10745.CURRENT_FLAG      ) D1 order by c4, c5, c3, c2 When querying in any subject area and you cross different dimensions, especially Type II slowly changing dimensions, if the result set appears to be short the first place to look is to see if that object has associated facts.

• Can somebody link me to some code where there is a fantastic or a nice use of Inheritance

  - by Soham

  I strongly believe that, reading code and reading good code is key to great programming. If not one of the many. I had been facing some problems in visualizing and having a "feel" of using inheritance to better my code architecture. Can somebody give me some link to good code to emulate, where folks have used inheritance in an absolute "kung-fooey ruthless" manner [in a good way]

• What do you code first to learn a new language, library, or framework?

  - by Griffin

  Every language, framework, and library has its own syntax, quirks, and pitfalls. What Program, Game, etc. do you code in order to learn these unique characteristics? How do you decide on what previous programming experience is applicable? I'd imagine that the task would have to be complicated enough to force you to use applicable programming techniques and idioms, but simple enough that it wouldn't take a ton of time.

• How does Python compile some its code in C?

  - by Howcan

  I read that some constructs of Python are more efficient because they are compiled in C. https://wiki.python.org/moin/PythonSpeed/PerformanceTips Some of the examples used were map() and filter(). I was wondering how Python is able to do this? It's generally interpreted, so how does some of the code get compiled while another is interpreted - and in a different language? Why not just compile the whole thing?

• How to process payments for a software (activation code)?

  - by jsoldi

  I want to sell software online and I need an easy to implement payment processing system. What I'm actually going to be selling is an activation code (one per purchase) that would activate the trial version of a product. I was about to use this one but I just found out that people without a paid email account (not hotmail or yahoo) can't process their orders, which I'm sure would discourage many, if not most, of the possible buyers.

• Is there a performance hit when running obfuscated code?

  - by nvivek

  All, I am proposing the addition of code obfuscation to the standard build process at my organization. One of the questions being asked is whether there is a performance hit to running obfuscated code vs. running unobfuscated code. What is your experience? Have you seen a reduction in performance at runtime because you obfuscated your Java or C# code? Thanks, VI

• How do you keep track of the authors of code?

  - by dustyprogrammer

  This is something I was never taught. I have seen alot of different types of authoring styles. I code primarily in Java and Python. I was wondering if there was a standard authoring style or if everything is freestyle. Also if you answer would you mind attaching the style you use to author files that your create at home or at work. I usually just go @author garbagecollector @company garbage inc.

• Is it OK to repeat code for unit tests?

  - by Pete

  I wrote some sorting algorithms for a class assignment and I also wrote a few tests to make sure the algorithms were implemented correctly. My tests are only like 10 lines long and there are 3 of them but only 1 line changes between the 3 so there is a lot of repeated code. Is it better to refactor this code into another method that is then called from each test? Wouldn't I then need to write another test to test the refactoring? Some of the variables can even be moved up to the class level. Should testing classes and methods follow the same rules as regular classes/methods? Here's an example: [TestMethod] public void MergeSortAssertArrayIsSorted() { int[] a = new int[1000]; Random rand = new Random(DateTime.Now.Millisecond); for(int i = 0; i < a.Length; i++) { a[i] = rand.Next(Int16.MaxValue); } int[] b = new int[1000]; a.CopyTo(b, 0); List<int> temp = b.ToList(); temp.Sort(); b = temp.ToArray(); MergeSort merge = new MergeSort(); merge.mergeSort(a, 0, a.Length - 1); CollectionAssert.AreEqual(a, b); } [TestMethod] public void InsertionSortAssertArrayIsSorted() { int[] a = new int[1000]; Random rand = new Random(DateTime.Now.Millisecond); for (int i = 0; i < a.Length; i++) { a[i] = rand.Next(Int16.MaxValue); } int[] b = new int[1000]; a.CopyTo(b, 0); List<int> temp = b.ToList(); temp.Sort(); b = temp.ToArray(); InsertionSort merge = new InsertionSort(); merge.insertionSort(a); CollectionAssert.AreEqual(a, b); }
