What happened to the this type of naming convention?

- by Smith

I have read so many docs about naming conventions, most recommending both Pascal and Camel naming conventions. Well, I agree to this, it's ok. This might not be pleasing to some, but I am just trying to get your opinion on why you name your objects and classes in a certain way. What happened to this type of naming conventions, and/or why are they bad? I want to name a structure, and I prefix it with "struct". My reason is that, with IntelliSense, I see all structures in one place, and anywhere I see the struct prefix, I know it's a "struct": structPerson structPosition another example is the enum, although I may not prefix it with "enum", but maybe with "enm": enmFruits enmSex again my reason is that in IntelliSense, I see all my enumerations in one place. Because .NET has so many built-in data structures, I think this helps me do less searching. Note that I used .NET in this example, but I welcome language agnostic answers.

How to read tags out of m4a files in .NET?

- by dkackman

I've got some heavily modified code that ultimately came from the Windows Media SDK that works great for reading tags out of MP3 and WMV files. Somewhere along the line, Windows Media Player added support for .m4a files (was it in Windows 7?) but the Windows Media API doesn't seem to reflect that addition (or at least IWMMetadataEditor2::OpenEx pukes on an .m4a file). What would be some good C# code or links on how to dig meta data tags out of m4a files? (Google has come up dry on the C# front.) UPDATE AtomicParsley did indeed end being the best approach. Since that code is a command line tool however I ended up having to create a managed wrapper around some of its functionality in order to use in-process. It is posted on google code if anyone else needs such a thing.

How can I implement full disk encryption for a disk containing Ubuntu with plausible deniability?

- by Rupert

I would like to have a disk that: has Ubuntu installed is fully encrypted is setup in such a way as to make denial of the existence of the Ubuntu install plausible Truecrypt provides the last two features but only for Windows: http://www.truecrypt.org/docs/?s=sys-encryption-supported-os The alternate installer for Ubuntu provides the first two features but not the last. I imagine that plausible deniability would be achieved by, at least: Having two installs of Ubuntu and 2 passphrases (or keyfiles) which would unencrypt each one. Moving any unencrypted data (such as /boot) onto a USB stick Are there any programs out there which support this feature set for Ubuntu?

match "//" comments with regex but not inside a quote

- by Wireless102

I need to match and replace some comments. for example: $test = "the url is http://www.google.com";// comment "<-- that quote needs to be matched I want to match the comments outside of the quotes, and replace any "'s in the comments with "'s. I have tried a number of patterns and different ways of running them but with no luck. The regex will be run with javascript to match php "//" comments UPDATE: I took the regex from borkweb below and modified it. used a function from http://ejohn.org/blog/search-and-dont-replace/ and came up with this: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title></title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <script type="text/javascript"> function t_replace(data){ var q = {}, ret = ""; data.replace(/(?:((["'\/]*(("[^"]*")|('[^']*'))?[\s]*)?[\/\/|#][^"|^']*))/g, function(value){ q[key] = value; }); for ( var key in q ){ ret = q[key]; } var text = data.split(ret); var out = ret + text[1]; out = out.replace(/"/g,"""); out = out.replace(/'/g,"'"); return text[0] + out; } </script> </head> <body> <script type="text/javascript"> document.write(t_replace("$test = \"the url is http://www.google.com\";// c'o\"mment \"\"\"<-- that quote needs to be matched")+"<br>"); document.write(t_replace("$test = 'the url is http://www.google.com';# c'o\"mment \"\"\"<-- that quote needs to be matched")); </script> </body> </html> it handles all the line comments outside of single or double quotes. Is there anyway I could optimize this function?

How to practically customize IE context menu?

- by bionicoder

I need to add one menu item in IE context menu. It is similar with Google customized context menu "Search Google for xxx" when you right click on IE. I did a research and found that overriding IDocHostUIHandler::ShowContextMenu in a IE BHO can customized IE context menu. The sample project can be found in Popup blocker project published in codeproject. It works well and is easy to implement. However this approach has a problem. The problem is it will conflict with other add-ons' context menu customization per MSDN. In MSDN Internet Explorer Center forum, there are some discussions about this topic. However there is not a proper implementation posted. If anybody has experience on this, please share your idea. Thanks!

Address Validation API

- by Paul

I have a task to validate addresses entered into a system I am currently creating. The system requires that address entered are validated against a valid data source. In the UK the dataset comes from the Royal Mail and is expensive to access. The data needed is post code info for the whold of europe to start with accessed by an API into the web application. There are a number of companies that offer this service, QAS Capscan Postcode anywhere These all offer the service I require. However this is expensive and in some cases not a complete data set. e.g. not Ireland I was also wondering if there would be a way to utalis the google maps API to validate this data via postal code and country. Would the google maps method be possible or do I have to go down the line of one of these expensive companies? Any thoughts on what line I should take.

iOS: game with facebook challenges

- by nazz_areno

I created a game for iPad and I want to challenge my facebook friends. I follow the iOS tutorial in "facebook dev docs", with the "Smash game", but it doesn't explain how to challenge a friend directly to a game. I will explain with an example: I want to start a new match and I want challenge a friend on facebook. Then I send him a request to install the app and when I detect that its app is installed I send him a request to play vs me. Then, when I finish the match I sent him my result and my friend do the same thing. But if I and my friend don't finish the match it is not possible to send another challenge. This scenario is not explained by facebook sdk. Is it necessary to use another instrument to do this situation?

Codebase for making a Flash-based interactive map with SVG vector data?

- by Mike

I'm looking for a way to take SVG path info (basically a string of coordinates) and dynamically draw it with Actionscript. Icing on the cake would be if those shapes could detect mouse events to trigger JS and dynamically change their appearance (fill, stroke, etc...). I'm currently trying something similar to this (http://raphaeljs.com/australia.html) using SVG but it's just too slow in IE. I've also tried Google's SVG Web (http://code.google.com/p/svgweb/) which basically does exactly what I'm looking for (it converts SVG to Flash in IE) but again, it's sloooooow - which is why I'm considering doing the whole shebang in Flash. Anyone know of some links to point me in the right direction?

PhysX: Joint friction/"stiff" joints

- by SigTerm

I'm working with physx (trying to add ik to ragdoll) at the moment. For some reason, all ragdoll joints are frictionless, and as a result, ragdoll tend to "wobble", especially when it is hung in the air and is connected to several moving kinematic actors. I would like to add friction to the joints and make them "stiff". Imagine a door (with extremely rusty hinge) that needs to be kicked several times to be open - i.e. it rotates around the hinge, but not much, quickly stops, and large force is required to make it rotate. Or think about art manikins (see google images for pictures) - their limbs move around, but they do not swing around freely. Unfortunately, I can't find anything related to joint friction in physx. I've checked documentation, google, and headers, and couldn't find anything useful. So, how do I implement stiff joints/joint friction with physx? (I think) I've seen physx games without that problem, so apparently there should be some way to do that.

Is it possible to run C++ binded with SDL+OpenGL code on a web browser?

- by unknownthreat

My client wants her website to have an application that renders 3D (light 3D stuff, we are drawing only flat squares in 3D world) but web programming is not my thing. So I am looking for something that can run a C++ program from a web browser. But I think, if this is the case, then the client side must download the program first, and that's not what I want. The client should only be able to use this application only on the website. I came across Google Native Client, which claims that it can run x86 native code in web applications. I haven't decide whether it is worth it or not and I don't know whether this is what I want or not, so I decided to ask experienced people about this. If I want to have something like this, is what I said above possible? Or I completely need other languages like Flex because it does not worth the trouble? Or is Google Native Client suitable for doing something like this?

How to use Ubuntu Touch manage-address-books.py?

Well I have been reading the docs for a few days and I found that I can "import" my contacts from a .csv file with the following: Alternatively you can import contacts from a csv file. The csv file should be in same format as /usr/share/demo-assets/contacts-data/data.csv. Replace the sample data.csv file with your own version and run manage-address-books.py create to import your contacts. But I can't figure out how to use manage-address-books.py create could anyone help me? I know that I can use syncevolution, but I want to sync my .csv file too.

What are your experiences selling on the Android Market?

- by RexOnRoids

I've been hearing some good things about Google's Android Market recently, and I might look into developing for android (currently develop for iPhone OS) at some point. Are any of you Android Developers, or simultaneously developing for iPhone AND Android? What have your experiences been for developing and selling your apps on the Android Market? Does Google have their act together in their app approval/deployment process? How does being a developer/merchant on the Android Market compare with the that of the App Store? Are you making money? Do you see this market as promising? Love it? Hate it? Share your experiences on the Android Market.

Where does Rails get it's datetime for creating records?

- by gwapEs9

I have a rails app with a data model called 'jobs' and i'm faced with a critical design choice crossroads. I don't know enough about Rails and it's inner workings to be able to say for sure what I should do despite a complete read of the rails and ruby docs. I want to be able to accurately display the age of a job record in days. So when a customer logs in, they can see that the job they submitted is 'x' days old. Where does a rails app on Heroku get it's time stamps? From Heroku? or the customers system clock? If a customer has a out of date system clock and submits a job, it could really mess up the sorting of their job list, not to mention me the overseer of job records. Any advice out there? EDIT: Just to be clear, i'm not asking how to list jobs by their date, but to which clock does a rails app on Heroku base it's records.

multitenancy with some data sharing

- by user55108

I'm in the planning stages of a new webapp, and I am leaning strongly toward a multitenancy model. The app has a file storage function, where the user can upload (and operate on) files. I would like the ability of the user to share these files, however. How is this typically accomplished in a multi-tenant model? The example would be something like google docs. Each user has their own files; they can edit and tag and build collections with these files. Then, they can share a doc or a collection with someone else for collaboration. If every user has their own Database and tables, what strategy would one use to allow this kind of sharing while minimizing duplication of files and associated metadata?

Parsing glGetShaderInfoLog() to get error info. Is this reliable, or is there a better way?

- by m4ttbush

I want to get a list of errors and their line numbers so I can display the error information different to how it's formatted in the error string, and also show the line in error. It looks easy enough to just parse the result of glGetShaderInfoLog(), look for "ERROR:" then read the next number up to : and then the next, and then the error description up to the next newline. But the OpenGL docs say "Application developers should not expect different OpenGL implementations to produce identical information logs." Which makes me worry that my code may behave incorrectly on different systems. I don't need them to be identical, I just need them to follow the same format. So is there a better way to get a list of errors with line number separate, is it safe to assume that they'll always follow the "ERROR: 0:123:" format, or is there simply no reliable way to do this? Thanks!

Secure Gmail login on web browser from external Java program

- by Zach Scrivena

Is there a secure way of logging into a Gmail account on a web browser, from an external Java program? I know the following works, but is there a safer alternative? Desktop.getDesktop().browse(new URI( "https://www.google.com/accounts/ServiceLoginAuth?continue=http://mail.google.com/gmail" + "&service=mail&Email=LOGIN&Passwd=PASSWORD&null=Sign+in")); Clarification: The external Java program is GmailAssistant, a Gmail notifier that already uses the IMAP capabilities of JavaMail. I just need a way of allowing the user to access the account directly in a web browser.

Recomendation for Webshop with API

- by m.sr

I'm searching for a webshop. The problem with my search is, that the webshop-software of my choice needs to have a useabel API or some interface for external applications. E.g. i need to place orders by an external application or need to get product descriptions or warehouse stock from the external application. I somehow would like to have a webshop wehere the webinterface is just one way to interact with the whole system. There are some other requirments, which have to be fullfilled, but i guess they are kind of common: running on linux MySQL (we already have MySQL-replication and backup in place) i like open source but i'm willing to pay for it, if it's worth it I found some webshops on the net - but perhaps you can tell me, if theres any hope for a webshop with a good API before i go and test all of them, on the first look i didn't find any docs about any interface to external applications for any of my search results. Thank you!

MediaWiki plugin for dynamic content via forms

- by Geek42

Are there any plugins for MediaWiki that would allow me to create a page that has a form at the top that when filled in populates tags further down in the document? Say someone would put a form with "Source Server:" and "Destination Server:" fields at the top. Once those were typed in it would automatically populate those names into the content lower so that when following the instructions you could just read the docs and not have to mentally replace things, and possibly mess it all up. I'm not looking to make pages that are permanent, just ones that can have values entered before they are followed. Any suggestions?

Hi! I feel sorry of askin all my little thingys here, but i can't find the answer via google. :( I'd like to switch tabs, replace an input value and call a function by one click. THE JS: function ApplyTableId(id) { var $tabs = $('#tabs').tabs(); $('a.stat').click(function() { $tabs.tabs('select', 2); // switch to third tab }); $('tableId').val('ga:'+id); // replace the input with id=tableId's val getAccountFeed(); // call an other function } The another JS, which will be called by the first script: function getAccountFeed() { var myFeedUri = 'https://www.google.com/analytics/feeds/accounts/default?max-results=50'; myService.getAccountFeed(myFeedUri, handleAccountFeed, handleError); } This is what i want to call, and here is the HTML: TAB1: <a class="stat" onClick="return ApplyTableId(this.getAttribute('id'));" id="7777777" />asd</a> TAB3: <input type="text" value="asd" id="tableId"/> Please tell me, what i did wrong :(

iphone web app: open directions in external maps application

- by munchybunch

I've seen the answers for opening the Maps app in a native iPhone app, but is there any way to do this in a web app? I've tried changing window.location to http://maps.google.com/maps?q=cupertino for example, to no avail. I've tried using a simple anchor tag linked to http://maps.google.com/maps?q=cupertino, also to no avail. Has anyone gotten this to work before? I'm working on a map-heavy application, and I'd like to provide users with directions at the end. I figured it would be easiest to simply open it up in the Map application. Note: I'm currently testing with just the simulator, could that lead to problems? My iPhone is down for the count at the moment.
