  • How to start recognizing design patterns as you are programming?

    - by Jon Erickson
    I have general academic knowledge of the various design patterns that are discussed in GoF and Head First Design Patterns, but I have a difficult time applying them to the code that I am writing. A goal for me this year is to be able to recognize design patterns that are emerging from the code that I write. Obviously this comes with experience (I have about 2 years in the field), but my question is how can I jumpstart my ability to recognize design patterns as I am coding, maybe a suggestion as to what patterns are easiest to start applying in client-server applications (in my case mainly c# webforms with ms sql db's, but this could definitely be language agnostic).

  • When are you truly forced to use UUID as part of the design?

    - by Pyrolistical
    I don't really see the point of UUID. I know the probability of a collision is effectively nil, but effectively nil is not even close to impossible. Can somebody give an example where you have no choice but to use UUID? From all the uses I've seen, I can see an alternative design without UUID. Sure the design might be slightly more complicated, but at least it doesn't have a non-zero probability of failure. UUID smells like global variables to me. There are many ways global variables make for simpler design, but its just lazy design.

  • Library and several small programs that use it: how should I structure my git repository?

    - by Dan
    I have some code that uses a library that I and others frequently modify (usually only by adding functions and methods). We each keep a local fork of the library for our own use. I also have a lot of small "driver" programs (~100 lines) that use the library and are used exclusively by me. Currently, I have both the driver programs and the library in the same repository, because I frequently make changes to both that are logically connected (adding a function to the library and then calling it). I'd like to merge my fork of the library with my co-workers' forks, but I don't want the driver programs to be part of the merged library. What's the best way to organize the git repositories for a large, shared library that needs to be merged frequently and a number of small programs that have changes that are connected to changes in the library?

  • DB Interface Design Optimization: Is it better to optimise for Fewer requests of smaller data size?

    - by Overflow
    The prevailing wisdom in webservices/web requests in general is to design your api such that you use as few requests as possible, and that each request returns therefore as much data as is needed In database design, the accepted wisdom is to design your queries to minimise size over the network, as opposed to minimizing the number of queries. They are both remote calls, so what gives?

  • Outlook unable to synchronize SharePoint library - error 0x80004005

    - by DLux
    We have one large library (~10 GB) on SharePoint that cannot be synchronized with Outlook, even if you only attempt to synch one of the smaller sub folders in the library. Other libraries (or other library sub folders) work fine with Outlook. This is with MOSS 2007 SP1 and Outlook 2007 SP2. The error is: Task 'SharePoint' reported error (0x80004005): 'An error occurred either in Outlook or SharePoint. Contact the SharePoint site administrator.' Reproducing the error Open up the large SharePoint document library in Internet Explorer From the Actions menu, select Connect to Outlook Select Allow on the stssync: security warning that pops up Outlook automatically tries an initial sync and sync status immediately shows the above error. Update 1: I verified the same issue occurs on Windows XP SP3 with IE 6 using Outlook 2007 SP2 and the same SharePoint library (it was originally tested on Windows 7). The issue is definitely related to the library or Outlook. Update 2: Using stsadm I exported the site with this large document library (8.6 GB 15,000 items) and imported it on to a development system. The result is the same on the development system - multiple clients are unable to connect Outlook to the library and get the 0x80004005 error above.

  • The C++ Standard Template Library as a BDB Database (part 1)

    - by Gregory Burd
    If you've used C++ you undoubtedly have used the Standard Template Libraries. Designed for in-memory management of data and collections of data this is a core aspect of all C++ programs. Berkeley DB is a database library with a variety of APIs designed to ease development, one of those APIs extends and makes use of the STL for persistent, transactional data storage. dbstl is an STL standard compatible API for Berkeley DB. You can make use of Berkeley DB via this API as if you are using C++ STL classes, and still make full use of Berkeley DB features. Being an STL library backed by a database, there are some important and useful features that dbstl can provide, while the C++ STL library can't. The following are a few typical use cases to use the dbstl extensions to the C++ STL for data storage. When data exceeds available physical memory.Berkeley DB dbstl can vastly improve performance when managing a dataset which is larger than available memory. Performance suffers when the data can't reside in memory because the OS is forced to use virtual memory and swap pages of memory to disk. Switching to BDB's dbstl improves performance while allowing you to keep using STL containers. When you need concurrent access to C++ STL containers.Few existing C++ STL implementations support concurrent access (create/read/update/delete) within a container, at best you'll find support for accessing different containers of the same type concurrently. With the Berkeley DB dbstl implementation you can concurrently access your data from multiple threads or processes with confidence in the outcome. When your objects are your database.You want to have object persistence in your application, and store objects in a database, and use the objects across different runs of your application without having to translate them to/from SQL. The dbstl is capable of storing complicated objects, even those not located on a continous chunk of memory space, directly to disk without any unnecessary overhead. These are a few reasons why you should consider using Berkeley DB's C++ STL support for your embedded database application. In the next few blog posts I'll show you a few examples of this approach, it's easy to use and easy to learn.

  • design of 'game engine' for small javascript games?

    - by Matt Ball
    I'm making a group of two or three simple javascript games for fun. After someone finishes one game, they'll be presented with a harder or easier version of another game depending on whether the original game was won or lost. I have a high-level question about the design of things: So far I've created a class for one game type that manages the interaction with the UI and the state of the game itself. But for tracking how many of the subgames have been won, or for understanding whether the next game presented should be more or less difficult, are there arguments to be made for making a 'game engine' class? How does the engine communicate to the games? For instance, when a game is won, how is that information relayed to the engine? Is there a better or more common design? (If you want to see what I have so far, the games are slowly taking shape here: https://github.com/yosemitebandit/candela and can be viewed at http://yosemitebandit.com/candela)

  • Book Review: Professional ASP.NET Design Patterns by Scott Millett

    - by Sam Abraham
    In the next few lines, I will be providing a brief review of Wrox’s Professional ASP.NET Design Patterns by Scott Millett. Design patterns have been a hot topic for many years as developers looked to do more with less, re-use as much code as possible by creating common libraries, as well as make their code easier to understand, extend and collaborate on. Scott Millett’s book covered classic and emerging patterns in a practical presentation that demonstrated with thorough examples how to put each pattern to use in the context of multi-tiered ASP.NET applications. The author’s unique approach and content earned him much kudos in the foreword by Scott Hanselman as well as online reviews. The book has 14 chapters of which 5 are dedicated to a comprehensive case study. Patterns covered therein include S.O.L.I.D, Gang of Four (GoF) as well as Martin Fowler’s Patterns of Enterprise Applications. Many thanks to the Wiley/Wrox User Group Program for their support of our West Palm Beach Developers’ Group. Best regards, --Sam You can access my reviews of books I recently read: Professional WCF 4.0 Inside Windows Communication Foundation Inside Microsoft SQL Server 2008 series

  • Logging library for (c++) games

    - by Klaim
    I know a lot of logging libraries but didn't test a lot of them. (GoogleLog, Pantheios, the coming boost::log library...) In games, especially in remote multiplayer and multithreaded games, logging is vital to debugging, even if you remove all logs in the end. Let's say I'm making a PC game (not console) that needs logs (multiplayer and multithreaded and/or multiprocess) and I have good reasons for looking for a library for logging (like, I don't have time or I'm not confident in my ability to write one correctly for my case). Assuming that I need : performance ease of use (allow streaming or formating or something like that) reliable (don't leak or crash!) cross-platform (at least Windows, MacOSX, Linux/Ubuntu) Wich logging library would you recommand? Currently, I think that boost::log is the most flexible one (you can even log to remotely!), but have not good performance update: is for high performance, but isn't released yet. Pantheios is often cited but I don't have comparison points on performance and usage. I've used my own lib for a long time but I know it don't manage multithreading so it's a big problem, even if it's fast enough. Google Log seems interesting, I just need to test it but if you already have compared those libs and more, your advice might be of good use. Games are often performance demanding while complex to debug so it would be good to know logging libraries that, in our specific case, have clear advantages.

  • La première beta de Ubuntu 10.04 LTS est sortie : nouveau design, nouveau kernel, nouveaux logiciels

    La beta 1 de Ubuntu 10.04 LTS est sortie Nouveau design, nouveau kernel, nouveaux logiciels Fini le marron dans Ubuntu. Le choc est rude, certes. Mais la première beta de la mouture 10.04 de l'OS consolera les nostalgique de l'ancien design de la distribution Linux (certainement) la plus connue au monde.

  • Photoshop Elements 9 VS Paintshop Photo Pro X3 For Web Design

    - by Brian
    I need a good image creation program for web design. I have downloaded both Elements 9 and Paintshop X3. So far I have found them both to be great programs. X3 seems like it has a lot of features, Elements seems like it's quite easy and stable to use. I think I'm going to go with Elements, but I wanted to get other opinions. Which program do you guys like better overall? What things do you think they lack for image creation/editing pertaining to web design, or what features do they have that are great for it? Thanks!

  • Design pattern and best practices

    - by insane-36
    I am an iphone developer. I am quite confident on developing iphone application with some minimal feature. I would consider myself as a fair application developer but the code I write is not so much structured. I make vey little use of MVC because I dont seem to find places to impose MVC. Most of the time, I create application with viewcontrollers and very few models only. How could I improve the skill for making my code more reusable, standard, easy and maintainable. I have seen few books on design patterns and tried few chapters myself but I dont seem to skip my habit. I know few of them but I am not being able to apply those patterns into my app. What is the best way to learn the design patterns and coding habit. Any kind of suggestion is warmly welcomed.

  • Best design for a memory resident tool

    - by Andrew S.
    I apologize if this tends more toward design that programming, but here goes. What design would you recommend for a database that is Memory resident Must run on windows, linux and (at a stretch) the mac Accept multiple queries simultaneously Have minimum overhead, since a search is expected to take <0.25s This program implements a domain-specific search. Think of it as a database, but one that takes advantage of domain specific information to outperform a convential database search (for example, with custom oracle indexing). We have a custom data structure for our data. Our protoype is a simple exe that constructs the database in memory each time it is run. We were thinking that perhaps this program would suffice, but augmented with sockets so it can listen for queries. This database will be static. Its contents will change infrequently. We expect queries, and the solution, to be delivered via a web service.

  • Events Driven Library XNA C#

    - by SchautDollar
    Language: C# w/ XNA Framework Relevant and Hopefully Helpful Background Info: I am making a library using the XNA framework for games I make with XNA. The Library has a folder(Namespace) dedication to the GUI. The GUI Controls inherit a base class hooked with the appropriate Interfaces. After a control is made, the programmer can hook the control with a "Frame" or "Module" that will tell the controls when to update and draw with an event. To make a "Frame" or "Module", you would inherit a class with the details coded in. (Kind of how win forms does it.) My reason for doing this is to simplify the process of creating menus with intractable controls. The only way I could think of for making the events for all the controls to function without being class specific would be to typecast a control to an object and typecast it back. (As I have read, this can be terribly inefficient.) Problem: Unfortunately, after I have implemented interfaces into the base classes and changed public delegate void ClickedHandler(BaseControl cntrl); to public delegate void ClickedHandler(Object cntrl, EventArgs e); my game has decreased in performance. This performance could be how I am firing the events, as what happens is the one menu will start fine, but then slowly but surely will freeze up. Every other frame works just fine, I just think it has something to do with the events and... that is why I am asking about them. Question: Is there a better more industry way of dealing with GUI Libraries other then using and implementing Events? Goal: To create a reusable feature rich XNA Control Library implementing performance enhancing standards and so on. Thank-you very much for taking your time to read this. I also hope this will help others possibly facing what I am facing right now.

  • Virtualized data centre&ndash;Part four: The design

    - by marc dekeyser
    Welcome back to the fourth post in this series! Today we will have a look at what Microsoft recommends as a “private cloud design” and what I will make of it. Whilst my own solution is based of the reference architecture, it is quite different indeed! An important thing to know is that, whilst I am using the private cloud as a reference, I am skipping most of the steps in designing a private cloud. If that is why you are here, please read the links at the end of the article and skim through my own content. A private cloud is much more process driven than just building a virtual infrastructure… The architecture of it all… So imagine for a minute that you have unlimited funds to build this lab of yours… You’d want redundancy on all levels and separation of each network where possible! Unfortunately we don’t have that luxury and, as you saw me hinting at in the previous article, our own design will be more limited but still quite capable! Networking From the networking perspective I will not have a fully redundant network, after all, this is but a lab environment! Thanks to Server 2012 I will be able to use bonding on my NIC’s and use LACP to improve the performance on that part. Storage As I mentioned in the previous article a Synology DS1218+ will be used for iSCSI provisioning. This device has 2 NICs on-board which can be bonded in to one 2 Gbps interface giving me a decent throughput and making the disks the most limiting factor in the storage design. Domain controllers and extra infrastructure Server 2012 completely supports running domain controllers virtualized and has no need to actually have a reachable DC when booting… That being said I need a remote access machine to power on the hosts (I have no need for them running 24/7) and a possible System Center VMM 2012 box (although server 2012 is not supported until SP1 :( ). Undecided on if I am to install those boxes separately or as a virtual machine… Which amounts to… Something like this pretty picture!                   Sources Microsoft Private Cloud Solutions Repository (en-US) http://social.technet.microsoft.com/wiki/contents/articles/12131.microsoft-private-cloud-solutions-repository-en-us.aspx Reference  Architecture: http://social.technet.microsoft.com/wiki/contents/articles/3819.reference-architecture-for-private-cloud.aspx Private Cloud Reference Model: http://social.technet.microsoft.com/wiki/contents/articles/4399.private-cloud-reference-model.aspx
