• Question regarding the ExtJS License

  - by stephemurdoch

  Let's say I create a CMS that uses ExtJS. I want to avoid the license fee, so I open-source the CMS on github. Now let's imagine that I make your friend Dave a website that uses my CMS. I spend three hundred hours designing a logo and designing the layout. Can I charge a fee for this, and would I be obliged to open-source Dave's website too or is it enough to just open-source the CMS? I find this LPGL license a little confusing. Say hi to Dave for me.

• TortoiseSvn Merge followed by Create Patch does not include new files

  - by JoelFan

  I am doing a Merge in TortoiseSvn, which modifies some files, deletes some, and adds some. Next I am doing a Create Patch to create a patch file with these changes. The problem is that the resulting patch file includes only the modifications and deletions, not the adds. I have discovered a workaround. If I revert the adds and then do an explicit Add of those files in TortoiseSVN, then do a Patch, it picks up everything, including the Adds. Is there a way to avoid this workaround?

• Use only some parts of Django?

  - by Hanno Fietz

  I like Django, but for a particular application I would like to use only parts of it, but I'm not familiar enough with how Django works on the inside, so maybe someone can point me into the right direction as to what I have to check out. Specifically, I want to use: The models and database abstraction The caching API, although I want to avoid database lookups by caching, not HTML generation, and since the caching framework in Django is intended for the latter, I'm not sure yet whether that's really appropriate. I would not use: Templating urlconfigs Or, more exactly, I'm neither using HTTP nor HTML. So basically, I have a different input / output chain than usual. Can this work? My personal killer feature in Django is the Object / database mapping that I can do with the models, so if there's another technology (doesn't have to be Python, I'm in the design phase and I'm pretty agnostic about languages and platforms) that gives me the same abilities, that would be great, too.

• Complicated idea - how to create car racing for my RPG game's players

  - by Donator

  So, I want to create car racing for my RPG game's players. Player can create race and choose how many participants can participate in race. After race is being created, other people can join it. When the maximum participants are collected, race begins. My idea, when the last participant joins, then instantly choose the winner (who's car is the best, that person wins), but how can I do it? If I choose to pick the winner after the last participant joins, then I have to put many queries in one page (select data from table, then delete the race, then select players' cars' statistics and pick the winner and then again, using mysql, send message to everyone). But this idea is really not optimal and it will lag cruelly for that last person. Maybe you have any ideas how I can avoid lag and make it more optimal. Thank you very much.

• Using Accelerometer in Wiimote for Physics Practicals

  - by Omar

  I have to develop some software in my school to utilize the accelerometer in the Wiimote for recording data from experiments, for example finding the acceleration and velocity of a moving object. I understand how the accelerometer values will be used but I am sort of stuck on the programming front. There is a set of things that I would like to do: Live streaming of data from the Wiimote via bluetooth Use the accelerometer values to find velocity and displacment via integration Plot a set of results Avoid the use of the infrared sensor on the Wiimote Please can anyone give me their thoughts on how to go about this. Also it would be great if people could direct me to existing projects that utizlise the wiimote. Also can someone suggest what would be the best programming language to use for this. My current bet is on using Visual basic. Any sort of help is greatly appretiated.

• sqL table is sorted by default

  - by Pramodtech

  I have simple SSIS package where I import data from flat file into sql table(MS sql 2005). File contains 70k rows and table has no primary key. Importing is sucessful but when I open sql table the order of rwos is different from the that of file. After observing closely I see that data in table is sorted by default by first column. Why this is happening? and how I can avoid default sort? Thanks.

• Easily switching ConnectionStrings on publish to Azure

  - by David Pfeffer

  I'm currently building an Azure Web Role. I am testing this project against a local database server on localhost. Then, when confident that the project is working, I publish it to Staging on Windows Azure. However, I also have to remember to change the connection string to point to the live SQL server on SQL Azure before deploying, and then change it back to localhost afterwards. Is there any nice way to automate this, or perhaps a different process to take to avoid the issue altogether? For example is there a way to have a configuration file for Azure that isn't updated with every deploy?

• Using an EJB inside a JAX-RS resource class in RestEasy?

  - by Laird Nelson

  I would like to have the following kind of resource class work when deployed under RestEasy in JBoss 6: @Path("Something") public class Foo { @EJB private SomeService service @GET public Object frobnicate() { assert service != null; // JBoss blows up here return result; } } Two questions: It is a limitation of RestEasy, not of the Java EE specification, right, that RestEasy can't inject anything annotated with @EJB? What have people done to work around this limitation? My developers are about to surge forward with hard-coded JNDI lookups (e.g. context.lookup(someHardCodedNameHere)) because no one can find a workaround to this specification violation at the present time. I really want to avoid this. Lastly, I've looked at using CDI, but the story here isn't much better as RestEasy and CDI still aren't talking to each other. Thanks in advance for any pointers.

• Custom roles in ASP.NET

  - by MainMa

  Hi, I am working on an ASP.NET website which uses forms authentication with a custom authentication mechanism (which sets e.Authenticated programmatically on protected void Login_Authenticate(object sender, AuthenticateEventArgs e)). I have an ASP.NET sitemap. Some elements must be displayed only to logged in users. Others must be displayed only to one, unique user (ie. administrator, identified by a user name which will never change). What I want to avoid: Set a custom role provider: too much code to write for a such basic thing, Transform the existing code, for example by removing sitemap and replacing it by a code-behind solution. What I want to do: A pure code-behind solution which will let me assign roles on authenticate event. Is it possible? How? If not, is there an easy-to-do workaround?

• a full-screen UIImagePickerController with the right scale?

  - by Kay

  Hi, I'm customizing my image picker controller and I want to have a full-screen viewfinder. I think this might be pretty an old topic and I found an answer here: http://www.gorbster.net/blog/archives/144 But what I want to know is if there's a way to achieve this without distorting the scale of the image. If I scale that clipped preview image, I'm distorting its original x-y ratio, and I want to avoid it. Is there a way to prevent the preview image from being clipped so that I could retain the original 1200x1600 ratio? Thanks!

• AdMob Android integration - what permissions to ask for?

  - by AngryHacker

  In the various videos on the AdMob integration, I've seen that only permission to access the internet is asked for: <uses-permission android:name="android.permission.INTERNET" /> Not that I am an expert in advertising, but wouldn't AdMob need the user's geographic location as well, so that they can serve location specific ads? Or avoid serving certain ads based on a location, like maybe not offering me a Big Mac if I am in India or not adverting a ham sandwich if I am in an Arab country? If AdMob needs those permissions, how do I ask for them?

• Adding HTML to the DOM through the client.

  - by Mantorok

  Hi all Just wanted your views on the most efficient way to render content on demand, the reason this has come to light is that I'm maintaining a AA compliant website and we recently added video to it, and one of the techniques to avoid invalidation was to add the HTML for the video to the DOM after the page has loaded - which is fine and working ok. However, I found 2 possible techniques and I would appreciate some views, the one I'm currently using is an AJAX call that returns the HTML, the other technique is a hidden field that contains the HTML - I'm presently using the former. The main reason I'm asking the question is because there may be times when this particular control is also requested via an AJAX call, so I would end up with back-to-back AJAX calls, which seems a bit inefficient to me. I hope this makes sense, are there any better techniques to achieve this? Am I worrying too much over the consecutive AJAX calls? Thanks

• JQuery. Hide elements before they rendered. Best practice

  - by Andrew Florko

  Hello everybody, I want to generate html layout with areas (divs, spans) that can be shown/hidden conditionally. These areas are hidden by default. If I call .hide method with jquery on document.ready these areas may blink (browsers render partially loaded documents). So I apply "display: none" style in html layout. I wonder what is the best practice to avoid blinking, because applying "display:none" breaks incapsulation rule - I know what jquery does with hide/show and use it. If jquery's hiding/showing implementation will change one day, I'll get the whole site unworkable. Thank you in advance

• YII Mail Generate unwanted ascii character in HTML mail

  I use YII-Mail just by copying the sample but I always get some ascii charcters in my generated links Where they come from and how to avoid them ? $message = new YiiMailMessage; $message->view = 'mail'; $message->setBody(array('model'=>$model), 'text/html'); $message->subject = Yii::t('tr','my subject'); $message->addTo('[email protected]'); $message->from = '[email protected]'; Yii::app()->mail->send($message); and in view file 'mail' <h1><?php echo(Yii::t('tr','This is HTML mail')); ?></h1> <?php echo CHtml::link('Mylink', array('controller/view', 'id'=>$model->id)); ?> The resulted email source looks like this <h1>This is HTML mail</h1> <a href=3D"/testdrive/index.php?r=3D ....

• How do I apply css for textboxes only but not for all the <input> types like CheckBoxes, etc.?

  - by George

  If all browsers supported attribute selectors, we could easily do the following: input[type='text'] { font:bold 0.8em 'courier new',courier,monospace; } input[type='radio'] { margin:0 20px; } input[type='checkbox'] { border:2px solid red; But I don't think all IE versions of ^ and greater support this. I think I'd like to avoid skins. Not sure why, other than I tried them and I recall having a negative experience. It was probably my lack of knowledge. Are there any issues in using and CSS, external or otherwise? What's the best way to handle this? Currently I am assigning separate classes to each control type.

• Need alternative field names for these reserved words

  - by MattSlay

  “type” and “class” are likely reserved or problematic words in C# and/or Ruby, two languages I may use to program against my new database schema in the future. So, in order to avoid potential conflicts with those languages, I’m looking for alternative names for these field names in my tables. In this case, it is from my Machines table, where I have: “class” field (values would be something like “manual” or “computerized”) and “type” field (values would be “lathe” or “mill”) I could call the fields “machineclass” and “machinetype”, but that is inconsistent with naming scheme in the rest of my schema (meaning, I do not re-use the table name in the field… For instance, I use Machine.name, not Machine.machinename) Any thought on this madness?

• Visual Studio 2008 adding incorrect working folders to TFS Workspace

  - by Bryan Rowe

  I am using Visual Studio 2008 with TFS. I have one workspace set up with one working folder. I map the root source control folder $/ to C:\TFS and get all code. When working on any project under the root, Visual Studio will randomly add incorrectly mapped working folders to my workspace. For example, it might map $/WebProject/ to C:\TFS\WebProject\DataAccess -- where the real files exist at C:\TFS\WebProject. Once it incorrectly adds these working folders, I can no longer open the solution. I am forced to remove the working folders that Visual Studio added and get latest from TFS. Has anyone experienced this? Is there something I can do to avoid running into this?

• memory alignment issues with union

  - by confucius

  Hi all, Is there guarantee, that memory for this object will be properly aligned if we create this object of this type in stack? union my_union { int value; char bytes[4]; }; If we create char bytes[4] in stack and then try to cast it to integer there might be alignment problem. We can avoid that problem by creating it in heap, however, is there such guarantee for union objects? Logically there should be, but I would like to confirm. Thanks.

• simple photo viewer

  - by Blaise

  Hi, I am fairly new to all this. I am trying to make a simple photo viewer with javascript or anything easy to alter. I just want a next and prev. button to take you between photos. Click next and next photo shows. Just that simple. I have a flash version but I would like to avoid using flash. I've been doing it the long way by making multiple pages, one for each photo and a button that repeats. I know there must be a better way but I just can't seem to figure it out. Please help

• Inherit static properties in subclass without redeclaration?

  - by David

  Hi, I'm having the same problem as this guy with the application I'm writing right now. The problem is that static properties are not being inherited in subclasses, and so if I use the static:: keyword in my main class, it sets the variable in my main class as well. It works if I redeclare the static variables in my subclass, but I expect to have a large number of static properties and subclasses and wish to avoid code duplication. The top-rated response on the page I linked has a link to a few "workarounds", but it seems to have 404'd. Can anyone lend me some help or perhaps point me in the direction of said workarounds?

• GWT application throws an exception when run on Google Chrome with compiler output style set to 'OBF

  - by Elifarley

  I'd like to know if you guys have faced the same problem I'm facing, and how you are dealing with it. Sometimes, a small and harmless change in a Java class ensues strange errors at runtime. These errors only happen if BOTH conditions below are true: 2) the application is run on Google Chrome, and 1) the GWT JavaScript compiler output style is set to 'OBF'. So, running the application on Firefox or IE always works. Running with the output style set to 'pretty' or 'detailed' always works, even on Google Chrome. Here's an example of error message that I got: "((TypeError): Property 'top' of object [object DOMWindow] is not a function stack" And here's what I have: - GWT 1.5.3 - GXT 1.2.4 - Google Chrome 4 and 5 - Windows XP In order to get rid of this Heisenbug, I have to either deploy my application without obfuscation or endure a time-consuming trial-and-error process in which I re-implement the change in slightly different ways and re-run the application, until the GWT compiler is happy with my code. Would you have a better idea on how to avoid this?

• Removing a result from Queryset

  - by Enrico

  Is there a simple way to discard/remove the last result in a queryset without affecting the db? I am trying to paginate results in Django, but don't know the total number of objects for a given query. I was planning on using next/previous or older/newer links, so I only need to know if this is the first and/or last page. First is easy to check. To check for the last page I can compare the number of results with the pagesize or make a second query. The first method fails to detect the last page when the number of results in the last set equals the pagesize (ie 100 records get broken into 10 pages with the last page containing exactly 10 results) and I would like to avoid making a second query. My current thought is that I should fetch pagesize + 1 results from the db. If the queryset length equals 11, I know this is not the last page and I want to discard the last result in the queryset before passing the queryset to the template.
