  • Relationships in a Chen ERD

    - by Nibroc A Rehpotsirhc
    I am working on a Chen ERD to model our organizations merchandise. Our central entity is a Style. We have supplemental entities of Color and Season. I am defining our assortment as the relationship between these three entities, and this relationship itself will have attributes and is defined by the three entities which participate in the mandatory relationship. The rules are; Many Styles can be offered in a Season, and a Style can be offered in many Seasons. Within a Season, a Style can be offered in Many Colors. I then have 2 other entities, one of which I believe is a weak entity, Climate, and the other may be weak, but I am not sure, this being Transaction Channel. I am thinking of these as relationships off of a relationship? Meaning, for a given Style/Color combination offered in a Season, it can be available through 1 or more Transaction Channels. Additionally, within a season, a given Style/Color combination can be intended for 1 or more Climates. Is it valid to have relationships off of relationships? Or does this requirement dictate that I should think of this Style/Color/Season relationship as an entity itself, and define the relationships to Climate and Transaction Channel off of this entity?

  • What kind of code would Kent Beck avoid unit testing?

    - by tieTYT
    I've been watching a few of the Is TDD Dead? talks on youtube, and one of the things that surprised me is Kent Beck seems to acknowledge that there are just some kinds of programs that aren't worth unit testing. For example, right here DHH says that Kent Beck is ... very happy to say "Well, TDD doesn't fit in this case, I'm just going to bail" It's frustrating to me that Kent Beck seems to acknowledge this, but nobody asks him to elaborate on it or give concrete examples. I'd like to know the situations where Kent Beck thinks TDD is a bad fit. Nobody can read his mind or speak for him, but I'm hoping he's been transparent enough through his books/tweets/whatever for someone to be able to answer. I'm not necessarily going to take what he says as gospel, but it would be useful to know that the times I've tried TDD and it just felt impossible/useless are situations that he would have bailed on it himself. Or, if it turned out he would have tested that code it'd suggest to me that I was approaching the process very wrong. I also think it would be enlightening to understand why he would bail on such projects. My opinion on why this is not a duplicate of "When is it appropriate to not unit test?" After skimming those answers I'm not satisfied. For example, look at UncleBob's answer. He doesn't even acknowledge that such a situation exists. I really think there's value in understanding Kent Beck's position, not just a general, "What's your opinion?" type of question. After all, he's the father of TDD.

  • How to use URLClassLoader to load a *.class file?

    - by DeletedAccount
    I'm playing around with Reflection and I thought I'd make something which loads a class and prints the names of all fields in the class. I've made a small hello world type of class to have something to inspect: kent@rat:~/eclipsews/SmallExample/bin$ ls IndependentClass.class kent@rat:~/eclipsews/SmallExample/bin$ java IndependentClass Hello! Goodbye! kent@rat:~/eclipsews/SmallExample/bin$ pwd /home/kent/eclipsews/SmallExample/bin kent@rat:~/eclipsews/SmallExample/bin$ Based on the above I draw two conclusions: It exists at /home/kent/eclipsews/SmallExample/bin/IndependentClass.class It works! (So it must be a proper .class-file which can be loaded by a class loader) Then the code which is to use Reflection: (Line which causes an exception is marked) import java.lang.reflect.Field; import java.net.MalformedURLException; import java.net.URL; import java.net.URLClassLoader; public class InspectClass { @SuppressWarnings("unchecked") public static void main(String[] args) throws ClassNotFoundException, MalformedURLException { URL classUrl; classUrl = new URL("file:///home/kent/eclipsews/SmallExample/bin/IndependentClass.class"); URL[] classUrls = { classUrl }; URLClassLoader ucl = new URLClassLoader(classUrls); Class c = ucl.loadClass("IndependentClass"); // LINE 14 for(Field f: c.getDeclaredFields()) { System.out.println("Field name" + f.getName()); } } } But when I run it I get: Exception in thread "main" java.lang.ClassNotFoundException: IndependentClass at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at InspectClass.main(InspectClass.java:14) My questions: What am I doing wrong above? How do I fix it? Is there a way to load several class files and iterate over them?

  • Types of ER Diagrams

    - by syrion
    I'm currently taking a class for database design, and we're using the ER diagram style designed by Peter Chen. I have a couple of problems with this style: Keys in relationships don't seem realistic. In practice, synthetic keys like "orderid" seem to be used in almost all tables, including association tables, but the Chen style diagrams heavily favor (table1key, table2key) compound keys. There is no notation for datatype. The diamond shape for associations is horrible, and produces a cluttered diagram. In general, it just seems hard to capture some relationships with the Chen system. What ERD style, if any, do you use? What has been the most popular in your workplaces? What tools have you used, or do you use, to create these diagrams?

  • Developer’s Life – Every Developer is a Superman

    - by Pinal Dave
    I enjoyed comparing developers to Spiderman so much, that I have decided to continue the trend and encourage some of my favorite people (developers) with another favorite superhero – Superman.  Superman is probably the most famous superhero – and one of the most inspiring. Everyone has their own favorite, but Superman has been the longest enduring of all comic book characters.  Clark Kent has inspired multiple movie series, TV shows, books, cartoons, and costumes.  Superman’s enduring popularity has been attributed to his superhuman strength, integrity, dedication to good, and his humility in keeping his identity a secret. So how are developers like Superman? Well, read on my list of reasons. Secret Identities They have secret identities.  I’m not saying that all developers wear thick glasses and go by an alias like “Clark Kent.”  But developers certainly work in the background, making sure everything runs smoothly, often without recognition.  Like Superman, when they have done their job right, no one knows they were there. Working Alone You don’t have to work alone.  Superman doesn’t have a sidekick like Robin or Bat Girl, but he is a major player in the Justice League.  Developers have amazing skills, and they shouldn’t be afraid to unite those skills to solve some of the world’s major problems (like slow networks). Daily Inspiration Developers are inspiring.  Clark Kent works at The Daily Planet, Metropolis’ newspaper, which is lucky because he can keep some of the publicity Superman inspires under wraps.  Developers might go unnoticed sometimes, but when people hear about some of the tasks they accomplish on a daily basis, it inspires awe. Discover Your Superpowers You have to discover your superpowers.  Clark Kent didn’t just wake up one morning with the full understanding that he could fly, leap tall buildings in a single bound, and was stronger than a speeding locomotive.  He slowly discovered these powers (after a few comic book-worthy misunderstandings!).  Developers are always learning and growing as well.  You probably won’t wake up with super powers, either, but years of practice and continuing education can get you close. Every Day is a New Day The story continues.  The Superman comic books are still being printed, and have been in print since 1938.  There have been two TV series, (one, Smallville, was on TV for ten seasons) and multiple cartoon adaptations.  There have been multiple movies, with many different actors.  A new reboot came out last year, and another is set to premier in 2016.   So, developers, when you are having a bad day or a problem seems unsolvable – remember, the story will continue!  There is always tomorrow. I hope you are all enjoying reading about developers-as-superheroes as much as I am enjoying writing about them.  Please tell me how else developers are like Superheroes in the comments – especially if you know any developers who are faster than a speeding bullet and can leap tall buildings in a single bound.

  • Upgrade TFS 2008 to 2010 on different server

    - by Chen
    Hi, I have been looking for a way to migrate and upgrade our TFS 2008 server to 2010 server preferably without losing any data. I have been looking at the TFS Integration Platform http://tfsintegration.codeplex.com/ and also Visual Studio 2010 TFS Upgrade Guide vs2010upgradeguide.codeplex.com Looking at the document TFS Integration Platform - Migration Guidance.xps using the first link, it seems to suggest that I could preserve all the data by first migrating the TFS 2008 from one server to the other and then upgrade the TFS 2008 to 2010. Is this true? Thank you, Chen

  • Industry Reports on Source Control Tools

    - by Kent Boogaart
    Hi, I'm looking for independent industry reports that compare and contrast the various source control tools out there. In particular, I care about Clearcase vs Sourcesafe vs SVN, but if the report includes other SCM systems that's fine. I need this for a client who wants to get a feel on exactly what they stand to gain switching to SVN (yes, from Clearcase and VSS). In other words, something I can use to sell it to their business. I'm hoping some case studies have been done on developer productivity with these tools and resultant reports made freely available. Thanks, Kent

    - by Rob Kent
    Apologies if this is the wrong place to ask this. I have an Android app on the market that has a reported problem on Droid and Nexus One (both with Android 2.1). I don't have access to the handset and cannot find anyone with one where I live. The problem I'm experiencing is partially explained at: http://stackoverflow.com/questions/2700983/problem-saving-file-on-motorola-droid-android-2-1. If you are an Android developer with either of those handsets, I'm happy to pay a reasonable fee if you'll debug the app for me. I'll send you the source. Please email me at [email protected]

  • What to choose for a multilingual site with support for Markdown and commenting

    - by Kent
    I want to publish articles at a multilingual site. I want to be able to write an article in two languages and have them available on separate URLs: thesite.foo/english-breakfast thesite.com/engelsk-frukost If the users web browser is set to English I'd like to show a small notice at the top of the Swedish version with a link to the English one. The link should have an appropriate rel attribute for a translation (search for hreflang at http://diveintohtml5.org/semantics.html). There should be a way to list all articles belonging to these sets: Swedish only, English only, Swedish versions + English only, English versions + Swedish only. I'd like to publish these as four RSS-feeds. And I would like to have two versions of the main site, one in Swedish (showing Swedish versions + English only) and one in English (showing English versions). I shall be able to write the articles using Markdown, as that is the formatting language I find most convenient. There should be a way for users to comment. And some kind of way for me to protect myself against comment spam. I am leaning towards learning Drupal. I suspect I'll have to code this behavior myself as a module. To be frank I'd rather work with Java. Is Drupal the way to go? Or is there something more suitable for this project?

  • What's the story with TRIM support?

    - by Kent Boogaart
    The situation with TRIM in Ubuntu has me utterly confused. I don't know whether I need to manually run it or not. Sources I've found are disparate and unclear. I have Ubuntu 10.04 with latest updates (including kernel 2.6.32-26). I have an Intel X-25M drive with latest firmware, and it is formatted as ext4. So, does TRIM support run automatically? If not, how do I check if I need to run it, and then how do I run it if necessary?

  • Text box select issue

    - by Kent Boogaart
    I have this issue where the entire text in text boxes is selected whilst I'm typing in it. For example, in FireFox search box I'd try to type "foo" but end up with "o" because I managed to type "fo" before everything was selected, and then typed "o" which replaced the "fo". When it happens, it is incessant - not just a one-off. But it doesn't happen all the time, and I haven't managed to figure out what causes it to start and stop. Is this a known problem with an easy solution? EDIT: this has nothing to do with touchpad. I get this occasionally even on a machine without one. I can usually rectify the issue just be alt-tabbing about a few times.

  • Where do I look to investigate how guided partitioning in the Ubuntu Server 12.04 installer works?

    - by Kent
    I would like to know how the installer, and in particular the guided partitioning for Ubuntu Server 12.04 works under the hood. I'm not interested in documentation, I want to check out the real scripts and the logic in them. How do you recommend I dig into this? Where on the ISO are these parts located? I don't know what the installer for Ubuntu is called, or how it is configured. I am well versed in programming languages and command line GNU/Linux.

  • Will GMails Greasemoney API help me: composing and sending messages, adding a button to the compose view, listing and sending drafts [migrated]

    - by Kent
    I want to create a Greasemonkey script for GMail and I've browsed through the GMail Greasemonkey 1.0 API documentation. I haven't fully understood what the API actually provides, which leads me to ask a few concrete questions. How will the API help if I want to: Add a button to the Compose view which executes some of my code. Compose and send a new message from scratch. List the current drafts. Pick a draft and send it. From what I can see it'll help me with 1 above, but I don't see any real interaction API parts which can help me with 2-4.

  • Alternative to distributed caching

    - by Chen
    Hi, There is a technical requirement to scale a new system easily. This new system consists of three tiered applications (as a batch processors). Each tier will contains at least 2 servers with the same application resides on each server. So, when one of the tier reaches peak performance, we could extend the scalability easily by adding a new server and the same application to off-load some of the processing loads. The problem is that one or two of the three tiers require heavy caching (about 3 million records and increasing). I'm thinking of using distributed caching system to overcome this problem but the new distributed caching system will means an additional point of failure as applications now need to interact with additional caching systems for processing. I'm currently looking at ncache but just wondering if there is an alternatives to this problem? or is there any other comparable distributed caching system that maybe similar or better than ncache and provide enterprise supports too? Thanks, Chen
