  • How were some language communities (eg, Ruby and Python) able to prevent fragmentation while others (eg, Lisp or ML) were not?

    - by chrisaycock
    The term "Lisp" (or "Lisp-like") is an umbrella for lots of different languages, such as Common Lisp, Scheme, and Arc. There is similar fragmentation is other language communities, like in ML. However, Ruby and Python have both managed to avoid this fate, where innovation occurred more on the implementation (like PyPy or YARV) instead of making changes to the language itself. Did the Ruby and Python communities do something special to prevent language fragmentation?

  • Naming convention for iOS

    - by RMDan
    I am learning Objective-C and iOS development and not sure what proper naming convention should be used. I understand how to use the label aspect of Obj-C methods but not the proper way to name each label. What is the best practice for naming methods, properties, objects, outlets, and actions? Also, Should different naming conventions be used between Obj-C code and C code? And if so what differences is there?

  • Independent Research on 1500 Companies Reveals Challenges in Performance Visibility – Part 1

    - by ndwyouell
    At the end of May I was joined by Professor Andy Neely of Cambridge University on a webinar, with an audience of over 700, to discuss the results of this extensive study which covered 13 countries and nearly every commercial and industrial sector.  What stunned both of us was not so much the number listening but the 100 questions they asked in just 1 hour.  This certainly represents a record in my experience and for those that organized the webinar. So what was all the fuss about?  Well, to begin with this was a pretty big sample and it represented organizations with over $100m sales across the USA, Europe, Africa and the Middle East. It also delivered some pretty interesting results across a wide range of EPM subjects such as profitability, planning and reporting.  Let’s look at some of those findings. We kicked off with profitability, one of the key factors in driving performance, or that is what you would think, but in fact 82% of our respondents said they did not have complete visibility into the profitability of their organization. 91% of these went further to say that, not surprisingly, this lack of knowledge into the profitability has implications with over half citing 3 or more implications.  Implications cited included misallocated resources, revenue opportunities not maximized, erroneous decisions made and impaired financial performance.  Quite a list of implications, especially given the difficult economic circumstances many organizations are operating in at this time. So why is this?  Well other results in the study point to some of the potential reasons.  Firstly 59% of respondents that use spreadsheets use them for monitoring profitability and 93% of all managers responding to the study use spreadsheets to gather and analyze information.  This is an enormous proportion given the problems with using spreadsheets based performance management systems that have been widely talked about for many years.  For profitability analysis this is particularly important when you consider the typical requirement will be to allocate cost and revenue across 6+ dimensions based on many different allocation methods.  Not something that can be done easily in spreadsheets plus it gets to be a nightmare once you want to change allocations, run different scenarios and then change the basis of your planning and budgeting! It is no wonder so many organizations have challenges in performance visibility. My next blog will look at the fragmented nature of many organizations’ planning.  In the meantime if you want to read the complete report on the research go to: http://www.oracle.com/webapps/dialogue/ns/dlgwelcome.jsp?p_ext=Y&p_dlg_id=10077790&src=7038701&Act=29

  • Which Continuous Integration framework do you use and why?

    - by Richard Warburton
    There are quite a few different Continuous Integration (CI) frameworks out there and I'm wondering which is the most popular. Which frameworks have you used at firms where you work? Is there any reason one CI framework is more popular than another - perhaps this is to do with the features it offers, things that integrate into it or maybe its just marketing? It seems like continuous integration is used more in the Java and .net worlds than say ruby or python. Why is this?

  • Does one's choice of 3d modeling software used during asset creation affect performance at runtime?

    - by user134143
    Does software used to create 3d assets (for game development specifically) have an impact on the efficiency of the program? In other words, is it possible to reduce the operating footprint of an application merely by utilizing alternative development software during production of 3d assets? If you use two different applications to create a 3-dimensional image of a box, can one of them result in better performance if aspects of the image are identical? I am attempting to get the information I need without causing unnecessary debate over specific software choice.

  • How to dynamically generate PDF documents

    - by Thomas
    I want to build a web application for generating stylish PDF documents. The layout should be based on a design templates and the data should come dynamically from the database. Ideally I want to design the template in a "publishing like" tool with placeholders and replace these placeholders by the web application with the data from the database. Think of something like an invoice generator, where a customer could choose from different invoice templates and the invoice data itself coming from the DB. Thanks for your ideas!

  • Good, simple reasons for having multiple environments

    - by smp7d
    Throughout my career I had worked at companies that had a collection of different environments for different purposes. We always had more or less our desktop environment, a test environment, a QA environment, a staging environment and a production environment. This went for both servers/applications and any data sources we were using. When I started at my current company I found that 90% of the apps were either developed on a desktop environment against production data sources or developed directly on the production server depending on the platform. I wasn't fazed because I was hired in part to make changes to improve the way the development team functioned, which was clear from my interview process. We slowly started to turn the philosophy and pretty soon, most of the apps could be run in either a desktop, test or production environment. Not too long after that staging came around as well. Now most of our developers see the benefit of this methodology and defend it vigilantly. However, we have a number of legacy apps that never got migrated. We also have a number of legacy programmers who think of this as a waste of time. Unfortunately, we got lip service but never full buy-in from management. We got what we thought was a commitment to invest substantially in this about a year ago, but nothing materialized despite the considerable planning that we put into it. Now we are finding that we need more and more environments. We need help from the server/network administration teams for setup and we need participation from the business stakeholders to support the release cycle. We are at a place now where a project can function what I consider "normally" only if you have the right people on the project and the time to set up the proper environments. I'd love to present a complete argument, but management really has no time and interest in hearing me out until there is a critical issue. I can't really articulate the benefits simply as it always just seemed second nature to me. I was wondering if there are any good, simple, irrefutable reasons for the separation of environments that would get managers with no development experience to get behind this idea. Are there any good resources/literature on the topic?

  • Transform 3d viewport vector to 2d vector

    - by learning_sam
    I am playing around with 3d transformations and came along an issue. I have a 3d vector already within the viewport and need to transform it to a 2d vector. (let's say my screen is 10x10) Does that just straight works like regualar transformation or is something different here? i.e.: I have the vector a = (2, 1, 0) within the viewport and want the 2d vector. Does that works like this and if yes how do I handle the "0" within the 3rd component?

    I am going to create a forum for my clan from a game and I was looking for a way to point/redirect to an ugly/long domain name from a shorter domain name.

So it would be something like www.niceclanname.domainext - www.unglyhardnametouseandremember.com/clan/ What are the available services that do this?

  • Mapping local folder with an UbuntuOne folder

    - by Titus
    TrendMicro's Safesync has a nice feature, you can map your local folder to a folder in the cloud with a different name, e.g: PC1: C:\my_documents\pictures === office_pictures c:\my_documents\docs === office_docs PC2: C:\my_documents\pictures === private_pictures c:\my_documents\docs === private_docs Would this be possible with UbuntuOne? The reason is that I have multiple computers, and I don't want all my "my_documents" folders to sync across work and personal life... Thanks for a reply or ideas for workarounds! ;-) Titus

  • Should I have a separate method for Update(), Insert(), etc., or have a generic Query() that would be able to handle all of these?

    - by Prayos
    I'm currently trying to write a class library for a connection to a database. Looking over it, there are several different types of queries: Select From, Update, Insert, etc. My question is, what is the best practice for writing these queries in a C# application? Should I have a separate method for each of them(i.e. Update(), Insert()), or have a generic Query() that would be able to handle all of these? Thanks for any and all help!

  • Does redirecting old site's URLs to new site's front page hurt a page's ranking?

    - by Kaivosukeltaja
    An old site that is being rewritten needs to have it's URLs redirected to the new site. There are a few hundred pages that may or may not have corresponding pages on the new site, probably with different slugs, and adding mappings manually will require more hours than we can spare. It was suggested that all old URLs be redirected to the new front page, but I remember reading somewhere that this confers a penalty in page rank because it's what link farmers do. Is this true or can we take the easy way out?
