• Firefox extension that overlays persistent iFrame?

  - by Crashalot

  Is it possible to build a Firefox extension that displays a floating, persistent iFrame over the page content? I know it's possible to add iFrames using XUL. For instance, you can add an iFrame to a persistent sidebar. However, I want the iFrame to float over the page content, not cause the content to shrink. So far, my only option is to add the iFrame to the DOM, then use CSS "fixed" positioning to float the iFrame. The iFrame must also persist across page loads, exactly as the sidebar does. Adding an iFrame to the DOM, unfortunately, causes the iFrame to vanish when the browser renders a new page (e.g., after clicking a link). Any clues? Thanks!

• Silverlight Project - Setting Reference to Copy Local false not working.

  - by cmaduro

  Why is it that when my Silverlight project is built, the output directory contains a bunch of culture specific directories: ar\System.Windows.Controls.resources.dll bg\System.Windows.Controls.resources.dll ca\System.Windows.Controls.resources.dll etc etc etc Also the root of the build output contains: System.Xml.Linq.dll System.windows.Controls.dll I have gone through the projects in my solution and made sure that "Copy Local" is set to false for all the referances of the mentioned dll files. Those 2 files were set to true, but I did switch them to false. Despite my effort to google an answer, I remain stuck.

• Run a JasperServer reprt via PHP and pass over the querystring.

  - by Ronedog

  I'm using Web Services to run some reports created in iReport on JasperServer. Inside the .jrxml file I can see the xml that holds the SQL for the report. Is it possible to pass this querystring over to JasperServer via Web Services, instead of hard coding the definition inside the .jrxml file. This is the string I would build in PHP, then pass over to JasperServer to be used in the execution of the report. <queryString> <![CDATA[SELECT * FROM table WHERE j=2]]> </queryString> Basically, I'm trying to find a way to dynamically create the SQL in PHP, then pass the SQL over to Jasper to run the report...is it even possible? Thanks.

• Freeware Programmer Calculator

  - by AdamC

  There have been lots of times in the past where a good programmer-oriented calculator would've saved me a lot of time. Lately, I've been doing quite a lot of bit manipulation, and having to do build/run to debug my calculations feels really slow. I've looked for something like this in the past, but found nothing that worked very well. The only thing that comes close is this one from AnalogX, but I can't get it to work or really do anything on my vista box which is where I'm doing most of my work at the moment. (btw - please send comments about my vista usage here;). Anyway, I'm looking for something for simple calculations using a C-like syntax with support for proper precenedce, operators, etc. Bonus points for cross-platform. The python interpreter was a great idea and is totally cross-platform. For windows only SpeQ is amazing. Thanks for the suggestions.

• UIImages not displaying in TableView on iPhone, but working in Simulator

  - by Graeme

  Hi, I have a UITable View that displays an image in the left hand side of the table cell, and it works fine in the simulator. Only problem is, once I ran it on my device no images appear. It's just a blank white space. Have checked that images are added to resource folder for build (which they are) and that capitals etc. match (which they do). Any ideas? Thanks. Code to display images: cell.imageView.layer.masksToBounds = YES; cell.imageView.layer.cornerRadius = 5.0; UIImage *image = [UIImage imageNamed:[[dog types] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]];; if ( image ) { cell.imageView.image = [image imageScaledToSize:CGSizeMake(50, 50)]; }

• Where is sdl-config installed on MacOS 10.6 (Snow Leopard)

  - by jmglov

  After installing SDL and SDL-devel in MacOS X 10.6 (Snow Leopard), trying to configure some source code that requires SDL yields: checking for sdl-config... no checking for SDL - version >= 1.2.0... no *** The sdl-config script installed by SDL could not be found *** If SDL was installed in PREFIX, make sure PREFIX/bin is in *** your path, or set the SDL_CONFIG environment variable to the *** full path to sdl-config. configure: error: *** SDL version 1.2.0 not found! Does anyone know where to find sdl-config? I guess I can build SDL from source, but why should I have to, when there exist pre-built packages?

• Bulk email notifications API for social networking site

  - by goombaloon

  I'm looking to build a social networking site that notifies followers of a particular user when new content has been posted by that user. Since the hope is that the site will eventually have thousands of users with thousands of followers, I'd prefer to use an outside product/service to send the emails rather than building the functionality into the application and dealing with scalability issues. I've looked at MailChimp and a few others out there. Since my use case isn't really email campaigns, these providers don't seem like the right solution. In fact, MailChimp support confirmed for me that my scenario doesn't fit for them. I'm sure others have run into this same requirement. What are others out there using? I'm using .NET so would like to target something that has a .NET wrapper if possible. Any advice would be most appreciated!

• Embed VLC player in GWT

  - by chrisnfoneur

  Hello, I want to embed a VLC player in my webapp build with Google's GWT. First I had a look at this page: http://wiki.videolan.org/GWT, which offers a nice solution but I add to implements all javascript functions calls (play, stop, fullscreen) with JSNI. Then I found gwt-player (hosted by Google code) which does all the job for me but the annoying part is that the project is not widely used (few posts each month on the project's group, not so many talks about it in blogs/forums...) Do you know another option to easly embed & control a VLC player in a GWT app ? My main goal is to play any video/audio file in a webapp and offer the user a fast/forward feature (set rate in VLC), is there any other player I could use ? I already had a look at Quicktime, Windows Media player & Flowplayer, none of them offers as much features as VLC. Thanks in advance & have a nice new year's eve. Chris

• Building TimeZone object in Java

  - by Harish

  I build a Java TimeZone object using the TimeZone String like GMT-8,GMT,PST,EST etc. This did not consider whether the timezone is daylight saving enabled or not.Now there is a requirement to include this check and instead of giving the input as PDT or EDT the daylight saving is given as a seperate flag.I am not sure whether TimeZone has a direct method to change the dayLight saving property of that TimeZone. So if I get an input like PST and DaylightSaving as true then I have to change the string as PDT.Whats even worse is sometimes I will get inputs like GMT-8 or GMT-6 with Day light flag as either true or false. Is there a way out ? I can't use thirdparty TimeZone related classes Code Sample: TimeZone timeZone = TimeZone.getTimeZone("EST"); TimeZone timeZone = TimeZone.getTimeZone("PST"); TimeZone timeZone = TimeZone.getTimeZone("GMT-8");

• Developing Installer Packages, are Visual Studio Setup Projects suitable for complex setups

  - by Robert

  Are "Visual Studio Setup" Projects suitable for complex setups in different versions? The application is rather large ( 500.000 lines of code) and is under continuous development. Every 6 to 10 month a new version gets released. We have multiple configuration files (INI and XML), registry keys, database migration scripts, etc. The application is in the progress of being migrated from VB6 to .NET . The old installer was build with Installshield. The feedback to Installshield is: Bad adaptability, bad reuse - thats way we are evaluating "Visual Studio Setup" as an alternative. Other products we consider: Free Solutions WiX NSIS Commercial Solutions Installshield (again..) Wise Advanced Installer sth. missing? Solutions we don't like to consider: Inno Setup (It just doesn't feel right)

• Creating a user-defined code generation system in PHP

  - by user270766

  My newest project that I'm looking to build with CodeIgniter would require some sort of system that would allow a user to drag and drop pre-defined functions/methods into mini-classes/objects and then run/test them in the browser. So it'd something similar to Scratch. I've designed a relational database that I think could work for this (storing the function names and have these classes "subscribe" to those functions) - but I'm wondering whether or not to go ahead with it. Is there a better way to do this or is there a system out there that would accomplish this for me? EDIT: It would have to be extremely simple for an end user, but hopefully be flexible enough to easily add more complex functionality in the future.

• What's wrong with the analogy between software and building construction?

  - by kuosan

  Many people like to think of building software as constructing a building so we have terms like building blocks and architecture. However, lately I've been to a couple of talks and most people say this analogy is wrong especially around the idea of having a non-coding software architect in a project. In my experience, good software architects are those who also write code so they won't design things that only looks good on paper. I've worked with several Architecture Astronauts, who have either limited or outdated experience in programming. These architecture astronauts quite often missed out critical details in their design and cause more harm than good in a project. This makes me wonder what are the differences between constructing a software and a building? How come in the building industry they can have architects who probably never build a house in their life and purely handles design work but not in the software development field?

• Common lisp error: "should be lambda expression"

  - by Zachary

  I just started learning Common Lisp a few days ago, and I'm trying to build a function that inserts a number into a tree. I'm getting an error, * - SYSTEM::%EXPAND-FORM: (CONS NIL LST) should be a lambda expression From googling around, it seems like this happens when you have too many sets of parenthesis, but after looking at this for an hour or so and changing things around, I can't figure out where I could be doing this. This is the code where it's happening: (defun insert (lst probe) (cond ((null lst) (cons probe lst)) ((equal (length lst) 1) (if (<= probe (first lst)) (cons probe lst) (append lst (list probe)))) ((equal (length lst) 2) ((cons nil lst) (append lst nil) (insertat nil lst 3) (cond ((<= probe (second lst)) (insert (first lst) probe)) ((> probe (fourth lst)) (insert (fifth lst) probe)) (t (insert (third lst) probe))))))) I'm pretty sure it's occurring after the ((equal (length lst) 2), where the idea is to insert an empty list into the existing list, then append an empty list onto the end, then insert an empty list into the middle.

• Why does Xcode launch the iPhone simulator when the iPad simulator is selected?

  - by Dr Dork

  When I open an existing iPad project in Xcode and "Build and Run" it, it launches the iPhone simulator when I have the iPad Simulator set as the active executable? Inside the iPhone simulator is a shrunken version of the iPad. What is going on? How do I get it to run the iPad simulator? Note: When the iPhone Simulator is running, I double checked the Hardware-Device setting and it's set to iPad. This is what I want, of course, but I don't want it to run the iPhone simulator. I seem to recall it used to run an iPad simulator. Is there such a thing or am I tripping and there is only an iPhone simulator that can run iPad apps? Thanks in advance for your help!

• Fluent NHibernate OptimisticLock.None() causes "The string 'none' is not a valid Boolean value."

  - by David Thomas Garcia

  I'm using the following mapping: public class LoadMap : IAutoMappingOverride<Load> { public void Override(AutoMapping<Load> mapping) { mapping.HasMany(x => x.Bids).OptimisticLock.None(); mapping.Version(x => x.Version); } } But when I try to create the session I get the following exception: [FormatException: The string 'none' is not a valid Boolean value.] [XmlSchemaValidationException: The 'optimistic-lock' attribute is invalid - The value 'none' is invalid according to its datatype 'http://www.w3.org/2001/XMLSchema:boolean' - The string 'none' is not a valid Boolean value.] I'm using NHibernate 2.1.2.4000 and I was using Fluent NHibernate 1.0RTM, but tried the latest build 636 just to be sure this isn't something that was fixed recently or something. As a side note, in case I'm doing this all wrong, I would like to be able to make changes to the .Bids list without incrementing Version. I saw an example on Ayende's blog that did what I wanted with properties.

• What are the differences between MSI and EXE installers, and which should I choose?

  - by Jared Harley

  I am working on an installer for a new version of my project (C#). Previously, I've used Inno Setup to create .exe files for installing my projects on other computers in the workplace. While reading through some tutorials, though, I came across Windows Installer XML, which uses XML files to build a .msi installer. My project will be available on a network share that all the employees have access to so they can install the software (I'm currently working on an update checker as well) What are the major differences between .exe and .msi installers? Why would I want to chose one over the other? Would either make more sense given my specific environment? I found some of the information at this question, but there was not a lot of information.

• chat application: pubsubhubbub vs xmpp

  - by sofia

  I'm unsure on the best stack to build a chat application. Currently I'm thinking of two main options: facebook tornado cons: does not use the main chat protocol xmpp but pubsubhubbub pros: i really like its simplicity for development (webserver + webframework); pubsubhubbub also seems simpler as a protocol than xmpp; and i know python xmpp + bosch, punjab, ejabberd cons: don't know erlang; overall seems a bit harder to develop pros: uses xmpp protocol The chat app will need to have the following: Private messages Public rooms Private rooms Chat history for rooms (not forever, just the last n messages) html embedding url to chat room Both options seem scalable so that's not really my worry (we're thinking of running the app in amazon's ec2 as well). I know there's a project that builds a xmpp server using tornado but it's not ready for production use and our deadline isn't that big. Basically my main worry is ease of development vs somehow regretting later using pubsubhubbub to develop a chat app but I read somewhere that PubSubHubbub might eventually replace XMPP as REST replaced SOAP - so what do you think?

• IntelliJ 9, Glassfish 2.1.1 & Maven2

  - by Xetius

  I have a Maven2 project which I am editing in IntelliJ IDEA 9.0.2. I am trying to build it and debug it within a Glassfish 2.1.1 container. This is only working sometimes. Occasionally it is giving me an error, telling me it can't deploy. Other times, it deploys, but does not run the filtering on the POM, not replacing a variable in the sun-web.xml file (and other container specific files) leaving it as ${targetenv} instead of replacing it with the value it should. I think I am missing something here, and have something very confused, but I have no idea what. Any help would be most gratefully received.

• http post with ant for file uploading

  - by paleozogt

  As part of my Ant build process, I'd like to upload files to a webserver via HTTP Post. Ant only comes with an HTTP Get task. However, Ant Contrib seems to have an HTTP Post task. The problem is that it doesn't have any authentication (like get does) or any way to specify a file upload (despite what the docs say, "rawFile" is not part of the distro). My question is: does Ant Contrib's Post task actually support what I want, but in a non-obvious way (perhaps I have to do it by hand)? Or is there some other way to do this?

• Is it easier to write a recursive-descent parser using an EBNF or a BNF?

  - by Vivin Paliath

  I've got a BNF and EBNF for a grammar. The BNF is obviously more verbose. I have a fairly good idea as far as using the BNF to build a recursive-descent parser; there are many resources for this. I am having trouble finding resources to convert an EBNF to a recursive-descent parser. Is this because it's more difficult? I recall from my CS theory classes that we went over EBNFs, but we didn't go over converting them into a recursive-descent parser. We did go over converting BNF's into a recursive-descent parser. The reason I'm asking is because the EBNF is more compact. From looking at the EBNF's in general, I notice that terms enclosed between { and } can be converted into a while loop. Are there any other guidelines or rules?

• iPhone - strange error when testing on simulator

  - by lostInTransit

  Hi I was testing my app on the simulator when it crashed on clicking a button of a UIAlertView. I stopped debugging there, made some changes to the code and built the app again. Now when I run the application, I get this error in the console Couldn't register com.myApp.debug with the bootstrap server. Error: unknown error code. This generally means that another instance of this process was already running or is hung in the debugger.Program received signal: “SIGABRT”. I tried removing the app from the simulator, doing a clean build but I still get this error when I try to run the app. Can someone please let me know what I should do to be able to run the app on my simulator again. Thanks.

• No Microphone error on iPod Touch

  - by Bob Vork

  I've build an iPhone app that should work on an iPod Touch as well, but I'm getting reports that the app is not working on iPod touches. It's displaying an error message saying there's no mic available on the device. The thing is, the app does nothing whatsoever with audio, and I can't find anything related in the project settings. The other problem is I don't have an iPod Touch available to test this myself. Are some people running an old firmware version? Am I compiling the wrong firmware version? To my surprise I couldn't find anything about this on SO or Google… Any help is appreciated
