• SQLSaturday #162 : Cambridge, England

  - by AaronBertrand

  Yesterday I presented at SQL Saturday #162 . My slide deck and samples are here: Slide Deck & Samples: Bertrand - T-SQL Bad Habits & Best Practices I also wanted to answer a question from an audience member after the session about how to generate YYYYMMDD strings to represent yesterday's date in order to append to a backup file name. In this case because we're probably not worried about performance (you're performing this calculation once), we can just use string conversion (see this blog...(read more)

• What is SOA ?

  - by llaszews

  First, let’s mention what SOA is not: • SOA is not the same thing as web services. Web Services implies the use of standard such as Java/JAX-RPC, .NET or REST. Web Services also implies the use of a WSDL, SOAP, and/or J2EE Connector Architecture (J2EE CA) and HTTP. SOA architectures can be implemented using J2EE CA, XML file transfer or Remote Procedural Call (RPC) over File Transfer Protocol (FTP), TCP/IP, Remote Method Invocation (RMI) or other protocols. In other words, Web Services are a very specific set of technologies. SOA is a concept and can be implemented in many different ways. Some very rudimentary, such as transfering flat files between applications. • SOA will not solve all of your problems. It will make your business more agile, increase business visibility, reduce integration costs and provide better reuse. However, if you don’t need help in these area or expect SOA to cure all of your IT problems, you are looking in the wrong place. • The concepts behind SOA are not new, but SOA is also not mature. SOA as it stands today has really only been around for 5 years. The concepts of standards based protocol handlers, predefined communication schemas and remote method invocation have been around for decades. So, what is SOA? SOA is an architectural blueprint, a way of developing applications, and a set of best practices. SOA is not an ‘out of the box’ solution you buy, install and then have up and running in a matter of months. SOA is a journey to a better way of doing business and the technology architecture to support this better way of doing business. SOA is also a broader set of technologies including more then just web services. Techologies like an Enterpirse Service Bus (ESB), Business Processs Execution Language (BPEL), message queues and Business Activity Monitoring (BAM) all are part of a SOA architecture.

• Is there a canonical book on general abstractions and modeling?

  - by David The Man

  I've been trying to understand the fundamentals of general abstractions and modeling: there are quite a lot of books when you search for abstractions, but most of those seem to be about learning object-oriented programming in a given language. Is there a book out there that's the de-facto standard for describing best practices, design methodologies, and other helpful information about general abstractions and modeling? What about that book makes it special?

• What is a software prototype?

  - by Stack Stock

  I understand this site is for programmers, and i have to ask specific coding question. I am doing a software engineering degree and i have been asked to reference at-least 7 books in my definition of prototyping. The best place to ask is here because most of you have probably read books on this and would be able to recommend books to me. I dont mind buying them from Amazon so if you could some books for me that define prototyping or a prototype i would really appreciate it.

• Brief material on C++ object-lifetime management and on passing and returning values/references

  - by dsign

  I was wondering if anybody can point to a post, pdf, or excerpt of a book containing the rules for C++ variable life-times and best practices for passing and returning function parameters. Things like when to pass by value and by reference, how to share ownership, avoid unnecessary copies, etc. This is not for a particular problem of mine, I've been programming in C++ for long enough to know the rules by instinct, but it is something that a lot of newcomers to the language stumble with, and I would be glad to point them to such a thing.

• My application quicklist goes missing when using "quickly submitubuntu"

  - by Kazade

  I'm trying to submit my app for the app showdown, but I've just noticed that when I use the "submitubuntu" Quickly command, my dynamic quicklist entries don't work. I think this is because the desktop file gets renamed from tickit.desktop to extras-tickit.desktop I'm coding a hacky fix to look for /usr/share/applications/extras-tickit.desktop and changing the argument for get_for_desktop_id() if it exists, but is there a better way? Can I stop Quickly renaming the desktop file?

• Attaching new animations onto skeleton via props, a good idea?

  - by Cardin

  I'm thinking of coding a game with an idea of mine. I've coded 2D games before, but I'm new to 3D programming, so I'd like to ask if this idea of mine is feasible or out of my depth. I'm making a game where there are many different characters for the player to choose from (JRPG style). So to save time, I have an idea of creating many different varied characters using a completely naked body mesh and animation skeleton, standardised across all characters. For example, by placing different hair, boots, armor props on the character mesh, new characters can be formed. Kinda like playing dress-up with a barbie doll. I'm thinking this can be done by having a bone on the prop that I can programmically attach to the main mesh. Also, I plan to have some props add new animations to the base skeleton, so equipping some particular props would give it new attack, damage, idle animations. This is because I can't expect the character to have the same swinging animation if he had a big sword or an axe. I think this might be possible if the prop has its own instance of the animation skeleton with just only the new animations, and parenting the base body mesh to this new skeleton. So all the base body mesh has are just the basic animations, other animations come from the props. My concerns are, 1) the props might not attach to the mesh properly and jitter a lot, 2) since prop and body are animated differently, the props and base mesh will cause visual artefacts, like the naked thighs showing through the pants when the character walks, 3) a custom pipeline have to be developed to export skeletons without mesh, and also to attach the base body mesh to a new skeleton during runtime in the game. So my question: are these features considered 'easy' to code? Or am I trying to do something few have ever succeeded with on their own? It feels like all these can be done given enough time and I know I definitely have to do a bit of bone matrix calculations, but I really don't want to drag out the development timeline unnecessarily from coding mathematically intense things or analyzing how to parse 3D export formats. I'm currently only at the Game Design stage, so if these features aren't a good idea, I can simply change the design of the game. (Unrelated to question) I could always, as last resort, have the characters have predetermined outfit and weapon selections so as to animate everything manually.

• Has test driven development (TDD) actually benefited a real world project?

  - by James

  I am not new to coding. I have been coding (seriously) for over 15 years now. I have always had some testing for my code. However, over the last few months I have been learning test driven design/development (TDD) using Ruby on Rails. So far, I'm not seeing the benefit. I see some benefit to writing tests for some things, but very few. And while I like the idea of writing the test first, I find I spend substantially more time trying to debug my tests to get them to say what I really mean than I do debugging actual code. This is probably because the test code is often substantially more complicated than the code it tests. I hope this is just inexperience with the available tools (RSpec in this case). I must say though, at this point, the level of frustration mixed with the disappointing lack of performance is beyond unacceptable. So far, the only value I'm seeing from TDD is a growing library of RSpec files that serve as templates for other projects/files. Which is not much more useful, maybe less useful, than the actual project code files. In reading the available literature, I notice that TDD seems to be a massive time sink up front, but pays off in the end. I'm just wondering, are there any real world examples? Does this massive frustration ever pay off in the real world? I really hope I did not miss this question somewhere else on here. I searched, but all the questions/answers are several years old at this point. It was a rare occasion when I found a developer who would say anything bad about TDD, which is why I have spent as much time on this as I have. However, I noticed that nobody seems to point to specific real-world examples. I did read one answer that said the guy debugging the code in 2011 would thank you for have a complete unit testing suite (I think that comment was made in 2008). So, I'm just wondering, after all these years, do we finally have any examples showing the payoff is real? Has anybody actually inherited or gone back to code that was designed/developed with TDD and has a complete set of unit tests and actually felt a payoff? Or did you find that you were spending so much time trying to figure out what the test was testing (and why it was important) that you just tossed out the whole mess and dug into the code?
