  • Spring Design By Contract: where to start?

    - by Build Monkey
    I am trying to put a "Contract" on a method call. My web application is in Spring 3. Is writing customs Annotations the right way to go. If so, any pointers( I didn't find anything in spring reference docs). Should I use tools like "Modern Jass", JML ...? Again any pointers will be useful. Thanks

  • Objective C - RegexKitLite - Parsing inner contents of a string, ie: start(.*?)end

    - by Stu
    Please consider the following: NSString *myText = @"mary had a little lamb"; NSString *regexString = @"mary(.*?)little"; for)NSString *match in [myText captureComponentsMatchedByRegex:regexString]){ NSLog(@"%@",match); } This will output to the console two things: 1) "mary had a little" 2) "had a" What I want is just the 2nd bit of information "had a". Is there is a way of matching a string and returning just the inner part? I'm fairly new to Objective C, this feels a rather trivial question yet I can't find a less messy way of doing this than incrementing an integer in the for loop and on the second iteration storing the "had a" in an NSString.

  • svn commit is hung at start of commit

    - by jwhitlock
    I'm commiting a large changeset, including a large binary file (180 MB) over a slow VPN connection. It looks for all the world like it is stalled. How can I diagnose where it is stuck? The output is: $ svn commit -m "My commit message" Connecting to deprecated signal QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString)` Local subversion is 1.6.9 on Linux, KDE 4.3, and svn status shows ML . L ws M ws/manage.py L ws/locales L ws/locales/ja_JP L ws/locales/ja_JP/LC_MESSAGES The process isn't using much of any resources. The server is Linux, served by Apache and mod_dav_svn, same subversion 1.6.9. I can't see any process that is handling the commit.

  • Start PyGTK cellrenderer edit from code

    - by mkotechno
    I have a treeview with an editable CellRendererText: self.renderer = gtk.CellRendererText() self.renderer.set_property('editable', True) But now I need to launch the edition from code instead from user, this is to focus the user attention in the fact he just created a new row and needs to be named. I tried this but does not work: self.renderer.start_editing( gtk.gdk.Event(gtk.gdk.NOTHING), self.treeview, str(index), gtk.gdk.Rectangle(), gtk.gdk.Rectangle(), 0) Neither does not throw errors, but the documentation about for what is each argument is not clear, in fact I really don't know if start_editing method is for this. All suggestions are welcome, thanks.

  • Entity Framework 4 / POCO - Where to start?

    - by Basiclife
    Hi, I've been programming for a while and have used LINQ-To-SQL and LINQ-To-Entities before (although when using entities it has been on a Entity/Table 1-1 relationship - ie not much different than L2SQL) I've been doing a lot of reading about Inversion of Control, Unit of Work, POCO and repository patterns and would like to use this methodology in my new applications. Where I'm struggling is finding a clear, concise beginners guide for EF4 which doesn't assume knowledge of EF1. The specific questions I need answered are: Code first / model first? Pros/cons in regards to EF4 (ie what happens if I do code first, change the code at a later date and need to regenerate my DB model - Does the data get preserved and transformed or dropped?) Assuming I'm going code-first (I'd like to see how EF4 converts that to a DB schema) how do I actually get started? Quite often I've seen articles with entity diagrams stating "So this is my entity model, now I'm going to ..." - Unfortunately, I'm unclear if they're created the model in the designer, saved it to generate code then stopped any further auto-code generation -or- They've coded (POCO)? classes and the somehow imported them into the deisgner view? I suppose what I really need is an understanding of where the "magic" comes from and how to add it myself if I'm not just generating an EF model directly from a DB. I'm aware the question is a little vague but I don't know what I don't know - So any input / correction / clarification appreciated. Needless to say, I don't expect anyone to sit here and teach me EF - I'd just like some good tutorials/forums/blogs/etc. for complete entity newbies Many thanks in advance

  • How should I start playing with 3D

    - by MarceloRamires
    I'm a developer for just about 6 months now, and since I enjoy programming I make a couple of little programs. I've started making encripters, calculators, tools, stuff to play with DropBox (hehe), stuff that play with bitmaps, drawing graphics, and even a program to update the MSN display image according to the artwork of the music you're listening yo on iTunes. Now I kind of ran off ideas of programs to deal with information, and I've had an idea: play around with 3d! so I've read a little about it and figured I'd have to have good notions on position and math on point spacial position (which I do, from my 3d modelling experience), but I don't know how to use API's for it, so I've 'simulated' simple 3d with a simple program I've made (it's just a spinning cube, please, first one to open it, comment here stating that it's safe, i've got no reason to harm anyone's pc.) One of my other hobbies is 3d modelling (completly amateur) and I'd like to mix these hobbies together! Here are some questions: 1) What would be a nice 3d development tool for a .NET programmer like me? 2) Is there a way of using 3d models made in 3DS Max ? (I intend on modelling characters) 3) What knowledges should I have in order to render it, and move it areound ? 4) Which API should I use ? NOTE: Not a dupe, I'm asking for directions specific for .NET development possibly using 3ds MAX, and there are no questions about it!

  • Where to start when programming process synchronization algorithms like clone/fork, semaphores

    - by David
    I am writing a program that simulates process synchronization. I am trying to implement the fork and semaphore techniques in C++, but am having trouble starting off. Do I just create a process and send it to fork from the very beginning? Is the program just going to be one infinite loop that goes back and forth between parent/child processes? And how do you create the idea of 'shared memory' in C++, explicit memory address or just some global variable? I just need to get the overall structure/idea of the flow of the program. Any references would be appreciated.

  • Streaming audio - where to start?

    - by Adam Davis
    I need to develop an embedded audio streaming server. Requirements: Voice quality or better Intended for low power wifi transmission Broad support in existing software and devices (ie, windows media player, quicktime, vlc, iPhone, Android, etc). Royalty/patent free, or cheap to license Preferences: Low overhead TCP/IP based streaming protocol Voice grade codec (easy to implement in software, no DSP, 32bit CPU if needed) Would be nice if it supported HTML5 browsers, but is there any codec (such as raw) that is supported by the latest browsers that is lower overhead than MP3? Therefore: What are the relevant streaming protocols I should be looking at? What are the relevant codecs I should be looking at? What transport streams should I be looking at? What am I missing, or where else should I be looking for this type of need?

  • SEO: Where do I start?

    - by James
    Hi, I am primarily a software developer however I tend to delve in some web development from time to time. I have recently been asked to have a look at a friends website as they are wanting to improve their position in search engine results i.e. google/yahoo etc. I am aware there is no guarentee that their position will change, however, I do know there are techniques/ways to make your website more visible to search engine spiders and to consequently improve your position in the rankings i.e. performing SEO. Before I started looking at the SEO of the site I did the following prerequsite checks: Ran the website through the W3C Markup Validator and the W3C CSS Validator services. Looked through the markup code manually (check for meta tags etc) Performed a thorough cross browser compatibility test. From those checks, the following was evident: No SEO has been performed on the site before. The website has been developed using a visual editing tool such as dreamweaver (as it failed the validation services miserably and tables where being used everywhere!) The site is fairly cross browser compatibile (only some slight issues with IE8 which are easily resolved). How the site navigation is, isn't very search engine friendly (e.g. index.php?page=home) I can see right away a major improvement for SEO (or I at least think) would be to change the way the website is structured i.e. change from using dynamic pages such as "index.php?page=home" and actually having pages called "home.html". Other area's would be to add meta tags to identify keywords, and then sprinkling these keywords over the pages. As I am a rookie in this department, could anyone give me some advice on how I could perform thorough SEO on this website? Thanks in advance.

  • Gracefully handling screen orientation change during activity start

    - by Steve H
    I'm trying to find a way to properly handle setting up an activity where its orientation is determined from data in the intent that launched it. This is for a game where the user can choose levels, some of which are int portrait orientation and some are landscape orientation. The problem I'm facing is that setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) doesn't take effect until the activity is fully loaded. This is a problem for me because I do some loading and image processing during startup, which I'd like to only have to do once. Currently, if the user chose a landscape level: the activity starts onCreate(), defaulting to portrait discovers from analysing its launching Intent that it should be in landscape orientation continues regardless all the way to onResume(), loading information and performing other setup tasks at this point setRequestedOrientation kicks in so the application runs through onPause() to onDestroy() it then again starts up from onCreate() and runs to onResume() repeating the setup from earlier Is there a way to avoid that and have it not perform the loading twice? For example, ideally, the activity would know before even onCreate was called whether it should be landscape or portrait depending on some property of the launching intent, but unless I've missed something that isn't possible. I've managed to hack together a way to avoid repeating the loading by checking a boolean before the time-consuming loading steps, but that doesn't seem like the right way of doing it. I imagine I could override onSaveInstanceState, but that would require a lot of additional coding. Is there a simple way to do this? Thanks!

  • Where to Start with build a personal site and WordPress, CSS and CMS

    - by Simon
    Hey guys im in a very confused state of mind at the moment and need some help with Word Press and generally starting a website. My parents have had a business for 20 years and have finally decided to get a website! As im studying IT and Business i said id get it done for them. Rather than design it from scratch i used a template which i bought from themeforest.net (awesome template!) and yesterday a friend mentioned in passing using word press as a CMS which i had never heard of before, and he left before i could ask any questions. SO basically i have a site working on my computer and i have no idea how to get it live as a .com or .com.au, so far as i can see wordpress is a blog with .wordpress.com which isnt what im looking for. Thanks in advance Simon

  • MSI Installer start auto-repair when service starts

    - by Josh Clark
    I have a WiX based MSI that installs a service and some shortcuts (and lots of other files that don't). The shortcut is created as described in the WiX docs with a registry key under HKCU as the key file. This is an all users install, but to get past ICE38, this registry key has to be under the current user. When the service starts (it runs under the SYSTEM account) it notices that that registry key isn't valid (at least of that user) and runs the install again to "repair". In the Event Log I get MsiInstaller Events 1001 and 1004 showing that "The resource 'HKEY_CURRENT_USER\SOFTWARE\MyInstaller\Foo' does not exist." This isn't surprising since the SYSTEM user wouldn't have this key. I turned on system wide MSI logging and the auto-repair created its log file in the C:\Windows\Temp folder rather than a specific user's TEMP folder which seems to imply the current user was SYSTEM (plus the log file shows the "Calling process" to be my service). Is there something I can do to disable the auto-repair functionality? Am I doing something wrong or breaking some MSI rule? Any hints on where to look next?

  • How should I start to play with 3D

    - by MarceloRamires
    I'm a developer for just about 6 months now, and since I enjoy programming I make a couple of little programs. I've startedmaking encripters, calculators, tools, stuff to play with DropBox (hehe), stuff that play with bitmaps, drawing graphics, and even a program to update the MSN display image according to the artwork of the music you're listening yo on iTunes. Now I kind of ran off ideas of programs to deal with information, and I've had an idea: play around with 3d! so I've read a little about it and figured I'd have to have good notions on position and math on point spacial position (which I do, from my 3d modelling experience), but I don't know how to use API's for it, so I've 'simulated' simple 3d with a simple program I've made (it's just a spinning cube, please, first one to open it, comment here stating that it's safe, i've got no reason to harm anyone's pc.) One of my other hobbies is 3d modelling (completly amateur) and I'd like to mix these hobbies together! Here are some questions: 1) What would be a nice 3d development tool for a .NET programmer like me? 2) Is there a way of using 3d models made in 3DS Max ? (I intend on modelling characters) 3) What knowledges should I have in order to render it, and move it areound ? 4) Which API should I use ? NOTE: Not a dupe, I'm asking for directions specific for .NET development possibly using 3ds MAX, and there's no question about it!
