  • The ETL from Hell - Diagnosing Batch System Performance Issues

    Too often, the batch systems that underlie a lot of database processing just grow without conscious design. When runs start to extend beyond their allotted time, and tuning no longer solves the problem, it is often discovered that batches are run in series, with draconian error handling. It is time to impose some rational design, and Nigel is a seasoned healer of batch processes.

  • Programming to ANSI standards (for engineering)

    - by Jake
    I am currently tasked to write a software to help engineers design standard compliant designs. If there is a bad design, software will report an error or warning. Maybe it's just me, but anyone who has done this should be familiar with the massive amounts of ANSI standards tables like this one: http://en.wikipedia.org/wiki/Nominal_Pipe_Size Computers are, as its name suggest, computing machines, not lookup machines. I feel that feeding formulas into computers and churning out standard compliant designs is much more efficient than doing memory intensive data lookups that are prone to human input errors and susceptible to "data updates". I actually think that there are formulas to calculate all those numbers, but nobody so far could give me that information. Anyone been through this before? What is THE best approach to this? Thanks for sharing.

  • Content Optimization only?

    - by danie7L T
    There are tons of discussions around tips&tricks to improve Search Engines "ranking" and SEOs. What if the focus of the webmaster/client is 100% set on the quality of the content with precise keywords in meta tags, clean design, regular articles updates, clean URLs and highly filtered external links leading to pages on websites dealing on the same,or related subjects; isn't it the job of a good search engine like Google to catch this website and show it in its front-page ? Or does Search Engines count on us to help them find us, and webmasters will always have to be up-to-date regarding SEO tools and rules updates on top of websites' design, browsers customization, progressive enhancement etc ?

  • Examples of Android Joystick Controls? [on hold]

    - by KRB
    I can't seem to find any well executed code examples for Android joystick controls. Whatever it may be, algorithms, pseudo code, actual code examples, strategies, or anything to assist with the design and implementation of Android joystick controls; I can't seem to find anything decent on the net. What are some well executed examples? More specifically, Pseudo Code Current Examples Idea/Design Functionality Description Controller Hints Related Directly to Android Architecture What kind of classes will I have making this? Will there be only one? How would this be implemented to the game architecture? All things I am thinking about. Cheers! UPDATE I've found this on the subject Joystick Example1, though I am still looking for different examples/resources. Answered my own question with a link to the code of the above video. It's a fantastic start to Android Joystick Controls.

  • How do I avoid the complexity concerns of frameworks while keeping my team marketable?

    - by Desolate Planet
    When deciding upon how to design a software project with my colleagues, most suggestions tend to be for using specific frameworks "because it's popular in the job market" or "that's the framework that gets recruiters on the phone," and never what I'm looking for which is, "because it's a good fit for the project as it makes the system more adaptive to future changes and makes life easier for developers." I didn't start looking at projects in this way until I started reading up on domain-driven design. I've found that the actual domain is hidden deep under the frameworks used and it's hard to learn the business processes that have been implemented by the software product. Is there a way to marry the two competing goals: getting exposure as a development team while still being able to avoid complexity? Are frameworks that compromise, or are there other solutions out there?

  • Validation and Verification explanation (Boehm) - I cannot understand its point

    - by user970696
    Hopefully my last thread about V&V as I found the B.Boehm is text which I just do not understand well (likely my technical English is not that good). http://csse.usc.edu/csse/TECHRPTS/1979/usccse79-501/usccse79-501.pdf Basically he says that verification is about checking that products derived from requirements baseline must correspond to it and that deviation leads only to changes in these derived products (design, code). But he says it begins with design and ends with acceptance tests (you can check the V model inside). The thing is, I have accepted ISO12207 in terms of all testing is validation, yet it does not make any sense here. In order to be sure the product complies with requirements (acceptance test) I need to test it. Also it says that validation problems means that requirements are bad and needs to be changed - which does not happen with testing that testers do, who just checks correspondence with requirements.

  • Is there ongoing work in the kernel team to improve battery life under linux?

    - by leousa
    I have read in some forums that the kernel team is working on improving battery life and energy efficiency in linux. Unfortunately our community really lags behind windows and mac in that regard. I would like to read about the reasons why this difference exists with other platforms. Is it purely due to closed hardware specs from vendors or does it has to be with kernel design issues? Apple devices with unix cores have amazing battery times, but they also design their own hardware...just want to understand this issues in a less technical way I know that recent kernel updates in Ubuntu have improved the battery life in most computers, but I was wondering if there is still development going on and where can I read more about it. Thanks in advance

  • Flash/SWF Editor For Ubuntu 12.10

    - by Chantelle
    First, thank you in advance for any help that you can give a recent transplant from Windows to Ubuntu. I have a question that I have been seeking the answer too but I draw a blank at every turn. I design websites, free of charge, for nonprofit organizations that are just starting and do not have the resources to hire a design firm. I am in need of a flash/swf editor and compiler. I had a program that I used with the awful previous O/S, however WINE would not run the program. Thank you in advance for any help that you can offer. Since I do not earn a dime for doing this, I would prefer if the program was open source, however any suggestions are greatly appreciated.

  • An Annotated Line of Business Application

    The Silverlight HyperVideo Player  has met with strong support and interest. This mini-tutorial is the first in a series that will walk through the design and delivery of this project. This series will pretend that the design existed before we began coding, and will not take you through its evolution over the months between December 2009 and March 2010. In short, this series is a drop-line exercise highlighting how the program works with a focus on teasing out general principles of creating...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Concatenating Rows

    Often in database design we store different values in rows to take advantage of a normalized design. However many times we need to combine multiple rows of data into one row for a report of some sort. New author Carl P. Anderson brings us some interesting T-SQL code to accomplish this.
