  • Ajax Rich Internet Application framework for Linux + Firefox _AND_ iPhone consumption

    - by Maroloccio
    For a zero-budget (e.g. University) project we need to build a rich web UI for Firefox and iPhone clients. Firm requirement: all technologies to be free and open-source. Nice-to-have: all development to be done in Java/Eclipse. I generally like the Google's AppEngine + GWT combo but this project will require much more interactivity than what's in GWT 2.0. Something along the lines of: http://www.smartclient.com/smartgwt/showcase/. I know trusty plain ol' GWT won't cut it this time. Straight question: is there something that does the sort of thing that SmartGWT does and works really well on Safari/iPhone? I would say the mobile experience is even more important for this project than the desktop one. Optional question: perhaps this is not the best route to go at all? How could we otherwise render a rich UI with such capabilities and interactivity on both screen sizes? Windows, drag-and-drop, advanced tabs, dynamic grids... We don't need to support any other mobile devices. Yet. ;-)

  • Good mobile oriented GWT widget library alternatives

    - by Michael Donohue
    I've been developing a travel planning site - tripgrep.com - which is built on appengine, GWT and smartgwt, among other technologies. It is still early days, and the site is now working well on my development environment, which is either a windows or mac computer. However, I am frequently talking up the website to my friends when we are at a bar or other venue, so I am standing there while they try to access the site via an iPhone, Android or Blackberry - I've witnessed all three. It has been painfully obvious that the browser based frontend takes a long time to download on a mobile device. I am pretty sure this is because of the javascript download for SmartGWT. So, I would like to look at alternatives to SmartGWT. What I like about SmartGWT is that it has a reasonable look and feel out of the box - I don't need to learn any design or css and it has an office application look. This is considerably better than the GWT built-in widgets, which just get a blue border. The better look-and-feel is why I went with SmartGWT early on. However, the slow load times are killing me on these mobile demos. So now I want a fast loading widget alternative that has good look-and-feel out of the box. The features I care about are: tabs, good form layout, Google maps API integration, grid data viewing. If those are all available in a library that loads quickly on a mobile device, then that's the library I want.

  • Completely bizarre Firefox CSS bug

    - by Jason
    I've been doing front end development for a long time, and I have NEVER come across a bug like this before... Save the following HTML to a file and view it in Firefox (mine is 3.6.3): <html xmlns="http://www.w3.org/1999/xhtml"> <head> <style type="text/css"> body { font-family: Helvetica, Sans-Serif;} h2 {font-weight: normal;} </style> </head> <body> <h2>Some normal text <strong>some bold text</strong> weird huh?</h2> </body> </html> If you don't want to give it a shot the output is like your cat walked across your keyboard while character map was turned on, except in the strong tags. I feel like this may be a font issue? When I get rid of font-weight: normal it goes back to normal, but I don't want everything to be bolded in my h2... Anyone have any ideas? More importantly, is anyone able to reproduce this?? Thanks.

  • Amazon access key showing in URL for Carrierwave and Fog

    - by kcurtin
    I just switched from storing my images uploaded via Carrierwave locally to using Amazon s3 via the fog gem in my Rails 3.1 app. While images are being added, when I click on an image in my application, the URL is providing my access key and a signature. Here is a sample URL (XXX replaced the string with the info): https://s3.amazonaws.com/bucketname/uploads/photo/image/2/IMG_4842.jpg?AWSAccessKeyId=XXX&Signature=XXX%3D&Expires=1332093418 This is happening in development (localhost:3000) and when I am using heroku for production. Here is my uploader: class ImageUploader < CarrierWave::Uploader::Base include CarrierWave::RMagick storage :fog def store_dir "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}" end process :convert => :jpg process :resize_to_limit => [640, 640] version :thumb do process :convert => :jpg process :resize_to_fill => [280, 205] end version :avatar do process :convert => :jpg process :resize_to_fill => [120, 120] end end And my config/initializers/fog.rb : CarrierWave.configure do |config| config.fog_credentials = { :provider => 'AWS', :aws_access_key_id => 'XXX', :aws_secret_access_key => 'XXX', } config.fog_directory = 'bucketname' config.fog_public = false end Anyone know how to make sure this information isn't available?

  • Which single IoC/DI container would you recommend using and why?

    - by Rob G
    I'm asking this question because it's a good way to gauge how the community at large feels about the various containers/frameworks and why. Also, whilst my expertise may lie in .Net development, I am very interested in which frameworks are popular (and why) in other languages. If I feel the need to start digging into Java for instance, then I'd like to hit the ground running with good (comfortable) knowledge that I'm starting in the right direction. Does Ruby even need one with all its magnificent dynamicism? I have my own opinions on the .Net front, and will probably add my own personal favourite in an answer below, but I'm interested in all languages and opinions here. With all that in mind, could you please state only one IoC/DI framework that you use and recommend with the language of choice (Java/Ruby/.Net/Smalltalk etc.) and your reasoning for your choice, and if someone has already answered your particular flavour, then you can just vote it up and add comments to it so that anyone looking for advice in future and see which frameworks are more than likely to work for them once they read your reasoning. I'm hoping that over time, the best ones will bubble up to the top. I realise that this question doesn't have only one correct answer, so I won't be choosing one - the community will decide which framework gets the most votes and why. Of course, if you really feel strongly opposed to a particular brand, you could take the reputation hit and vote it down too, and this question can serve as a true wiki-style entry for research into this field. Remember, only one IoC per answer you write please - if you feel the need to promote two frameworks, then write two answers with your reasoning inside for each choice - then others in the community can agree or disagree with you.

  • Linux USB debug connection to LuminaryMicro evaluation board

    - by mikelong
    Hi, I am trying to connect a Stellaris LM3S8962 evaluation kit to a linux host machine. I am using the CodeSourcery G++ for the development toolchain. When I try to run a helloworld example the connection fails with this message: arm-stellaris-eabi-sprite: error: E104. I/O Error communicating with USB Device. arm-stellaris-eabi-sprite: waiting for GDB connection, to pass error along warning: Remote failure reply: E.fatal.E104. I/O Error communicating with USB Device. arm-stellaris-eabi-sprite: error: E002.

  • How do I stop the m2eclipse plugin interfering with command line mvn builds?

    - by locka
    I use the m2eclipse plugin in Eclipse so that I can import a Maven project. The plugin reads the pom.xml and sorts out the dependencies in the projects in an Eclipse friendly way so I'm not looking at a sea of broken references and errors. I use Eclipse for code development however I usually build the projects from the command line, e.g. "mvn clean install". Unfortunately when I do this, m2eclipse detects disk activity and attempts to rebuild the workspace. This interferes with the command line build and sometimes results in a race condition. For example the command line might be in its clean phase but fails because it tries to delete a file or directory which is locked during the workspace rebuild. Aside from that workspace rebuilding is incredibly slow, and between failed builds and wasted CPU my build process is 2-3x longer than it should be. It isn't an option to not use Eclipse (e.g. to use Netbeans), or to disable m2eclipse. It is a useful plugin except for this behaviour. So my question is, how do I stop m2eclipse from rebuilding the workspace all the time? Can I invoke a manual refresh and otherwise disable this behaviour?

  • iPhone UI layout debugging

    - by Cruinh
    I have this chronic issue with iPhone UI development where views sometimes seem to appear on the screen in a location different than what is reported by their frame property. Here is what I am doing to try to debug the issue: UIView *currentView = self.view; while (currentView!=nil) { NSLog(@"frame: %f,%f,%f,%f", currentView.frame.origin.x, currentView.frame.origin.y, currentView.frame.size.width, currentView.frame.size.height); currentView = currentView.superview; } I expect this should show me the coordinates and size of each element up the hierarchy from the given view to the app's root UIWindow element, with the coordinates for each element relative to its parent. However, that does not seem to be the case. In my current situation, I have a UI I'm trying to debug where every other time I rotate the device, the whole UI shifts up or down 20 pixels, yet the code block above reports exactly the same numbers every time. I tried calling the above code after as much as a second delay, but that the numbers still come out the same each time. Does anyone know a better way to inspect the screen coordinates of UI elements? If I can detect when one is wrong, I can compensate for the problem when it appears.

  • Loading a class file immediately AFTER startup

    - by Striker
    We have a few war files deployed inside an ear file. Some of the war files have a class that caches static data from our PLM system in singletons. Since some of the classes take several minutes to load we use the load-on-startup in the web.xml to load them ahead of time. This all works fine until we attempt to re-deploy the application on our production servers. (WebLogic 10.3) We get an exception from our PLM API about a dll already being loaded. Our PLM vendor has confirmed that this is a problem and stated that they don't support using the load-on-startup. This is also a huge problem on our development boxes where we have redeploy the app all the time. Most of us, when we're not working on one of the apps that uses a cache, have them commented out. Obviously we can't do that for the production servers. Right now we transfer the ear to the production server, deploy it in the console, wait for it to crash, shut the app server instance down and then start it up again. We need to find a way around this... One suggestion was to create a servlet that we can call after the server boots that will load the various caches. While this will work I'm looking for something a bit cleaner. Is there anyway to detect once the server started and then fire off the methods? Thanks.

  • Getting my foot in the SCADA door, how?

    - by bibby
    I keep hearing that I should learn SCADA and its PLC language to upgrade my career. While I enjoy currently being a web and mobile development privateer, the prospects of working for a municipality or industrial entity has its appeals (since I am trying to grow a family). Over the years, I've tought myself to skillfully use php, javascript, java, perl, awk, bash. Surely, these language skills can tranfer somewhat to SCADA's logic controller language. Without any formal training in CS (music major!) other than at the workplace, I wouldn't have been able to pick up those languages and run with them had it not been for their open documentation and free-to-install or already-installed interpreters/compilers. I can't see that this is true with SCADA, and I'm hoping that I'm wrong. Ideally, I'd like to be able to apply for a job that requires [A,B,C] and suggest that they hire me because I already know [A & B]; that they wouldn't have to do a ground-up training with someone that's never programmed before. So, finally, the question; How do I "learn" SCADA? Are there sites and docs? What's going to help me get my foot in the door? Any insight is appreciated. Thanks!

  • Automated Oracle Schema Migration Tool

    - by Dave Jarvis
    What are some tools (commercial or OSS) that provide a GUI-based mechanism for creating schema upgrade scripts? To be clear, here are the tool responsibilities: Obtain connection to recent schema version (called "source"). Obtain connection to previous schema version (called "target"). Compare all schema objects between source and target. Create a script to make the target schema equivalent to the source schema ("upgrade script"). Create a rollback script to revert the source schema, used if the upgrade script fails (at any point). Create individual files for schema objects. The software must: Use ALTER TABLE instead of DROP and CREATE for renamed columns. Work with Oracle 10g or greater. Create scripts that can be batch executed (via command-line). Trivial installation process. (Bonus) Create scripts that can be executed with SQL*Plus. Here are some examples (from StackOverflow, ServerFault, and Google searches): Change Manager Oracle SQL Developer Software that does not meet the criteria, or cannot be evaluated, includes: TOAD PL/SQL Developer - Invalid SQL*Plus statements. Does not produce ALTER statements. SQL Fairy - No installer. Complex installation process. Poorly documented. DBDiff - Crippled data set evaluation, poor customer support. OrbitDB - Crippled data set evaluation. SchemaCrawler - No easily identifiable download version for Oracle databases. SQL Compare - SQL Server, not Oracle. LiquiBase - Requires changing the development process. No installer. Manually edit config files. Does not recognize its own baseUrl parameter. The only acceptable crippling of the evaluation version is by time. Crippling by restricting the number of tables and views hides possible bugs that are only visible in the software during the attempt to migrate hundreds of tables and views.

  • Dynamically add columns to a listbox

    - by mgroves
    I'm brand new to Windows Phone 7 development, and almost as equally new to Silverlight. I have a ListBox with a DataTemplate, StackPanel, and TextBlocks like so: <ListBox Height="355" HorizontalAlignment="Left" Margin="6,291,0,0" Name="detailsList" VerticalAlignment="Top" Width="474" Background="#36FFFFFF"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <TextBlock Width="50" Text="{Binding Ticker}" /> <TextBlock Width="50" Text="{Binding Price}" /> <TextBlock Width="50" Text="{Binding GainLoss}" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> I have some C# code to populate it: var info = new List<StockInfo>(); info.Add(new StockInfo { Ticker = "C", Price = "5.18", GainLoss = "10" }); info.Add(new StockInfo { Ticker = "WEN", Price = "4.18", GainLoss = "12" }); info.Add(new StockInfo { Ticker = "CBB", Price = "5.22", GainLoss = "210" }); detailsList.ItemsSource = info; And that all works fine. My question is: how do I add/remove additional 'textblocks' to the listbox dynamically (at runtime)? Also, how do I put column headers on the list box?

  • Testing performance of queries in mysl

    - by Unreason
    I am trying to setup a script that would test performance of queries on a development mysql server. Here are more details: I have root access I am the only user accessing the server Mostly interested in InnoDB performance The queries I am optimizing are mostly search queries (SELECT ... LIKE '%xy%') What I want to do is to create reliable testing environment for measuring the speed of a single query, free from dependencies on other variables. Till now I have been using SQL_NO_CACHE, but sometimes the results of such tests also show caching behaviour - taking much longer to execute on the first run and taking less time on subsequent runs. If someone can explain this behaviour in full detail I might stick to using SQL_NO_CACHE; I do believe that it might be due to file system cache and/or caching of indexes used to execute the query, as this post explains. It is not clear to me when Buffer Pool and Key Buffer get invalidated or how they might interfere with testing. So, short of restarting mysql server, how would you recommend to setup an environment that would be reliable in determining if one query performs better then the other?

  • Help to Install Eclipse for A Netbeans Users

    - by Yan Cheng CHEOK
    I had been using Netbeans all the while to develop Swing application. So far, I am a Happy Netbeans User Currently, I had a project (GWT, J2EE and Swing), which I need to use Eclipse (Please do not ask Why) Here is the step I had been taken. Download Eclipse IDE for Java EE Developers (190 MB) from http://www.eclipse.org/downloads/ I thought this should be the correct choice, as I see most features are found in that edition http://www.eclipse.org/downloads/packages/compare-packages After struggling a while to get use to the user interface of Eclipse, I still cannot find a Visual GUI Editor! After doing some Googling, I realize I need to install something called Plugins However, tones of plugins which had similar features has confused me, as I found http://www.cloudgarden.com/jigloo/index.html http://www.eclipse.org/vep/WebContent/main.php http://code.google.com/p/visualswing4eclipse/ This makes me even more confuse? Which plugin I should use to develop a Swing based application? Most of them seems not up-to-dated. Or, is there any complete bundle I can download, where 1 click, will install all the necessary Swing development tools for me? I just miss my Netbeans :( I really appreciate their team, who make the installation work so easy. One click button install, all the necessary tools just come to me

  • Querying a database using Cocoa.

    - by S1syphus
    Hello everybody. Before I start a disclaimer, I should add a little disclaimer, that I am relatively new to Cocoa development and C in general. However I do have a copy of 'Cocoa Programming for Mac OS X 3rd edition' by Aaron Hillegass, which I am working through and using as a base, if anybody has a copy I am using the 'AmaZone' example on page 346 as a template and base. I trying to develop a small client app that takes a search string then displays results from a database accordingly. The database will contain a: list of files, their location, description & creation date, so for the moment the field number and types will remain the same. After looking around on SO, I saw something like: NSURL *myURL = [NSURL URLWithString:@"http://www.myserver.com/results.php"]; NSArray *sqlResults = [[NSArray alloc] initWithContentsOfURL:myURL]; I've worked with php before, so my current thinking after seeing this is create a php script on the server that queries the database, and creates an XML output. And with the XML response, just parse it. Would this be ok? as is there any major pitfalls anybody can see, that I can't. I know there are some database bundles, I've had a look at BaseTen for Postgres, but being relatively new to this, didn't want to get in over my head. Or if anybody else has any other suggestions and ideas, they would be greatly appreciated.

  • PHP: Aggregate Model Classes or Uber Model Classes?

    - by sunwukung
    In many of the discussions regarding the M in MVC, (sidestepping ORM controversies for a moment), I commonly see Model classes described as object representations of table data (be that an Active Record, Table Gateway, Row Gateway or Domain Model/Mapper). Martin Fowler warns against the development of an anemic domain model, i.e. a class that is nothing more than a wrapper for CRUD functionality. I've been working on an MVC application for a couple of months now. The DBAL in the application I'm working on started out simple (on account of my understanding - oh the benefits of hindsight), and is organised so that Controllers invoke Business Logic classes, that in turn access the database via DAO/Transaction Scripts pertinent to the task at hand. There are a few "Entity" classes that aggregate these DAO objects to provide a convenient CRUD wrapper, but also embody some of the "behaviour" of that Domain concept (for example, a user - since it's easy to isolate). Taking a look at some of the code, and thinking along refactoring some of the code into a Rich Domain Model, it occurred to me that were I to try and wrap the CRUD routines and behaviour of say, a Company into a single "Model" class, that would be a sizeable class. So, my question is this: do Models represent domain objects, business logic, service layers, all of the above combined? How do you go about defining the responsibilities for these components?

I've done a lot of work ensuring security around persistant login cookies, and I've decided to request the password from any user that logged in using a persistant login cookie before being allowed to make any changes that could be malicious. This request would only happen once to confirm the user is who they say they are and will last throughout the session. At present, any requests that meet this criteria has their request information stored in session and then the user is forwarded to a page to confirm their password. Once confirmed, the user's original request is then performed and the requestion information removed from session. What I would like to do is avoid all this redirection and minimize what's held in session (even if it's just for a small time), thus improving usability and convenience for the user. I believe that a jQuery overlay could allow me to prompt the user for their password (if required) and then continue to submit the request if successful. I would of originally used ThickBox, but since that's now deprecated I don't see the benefit in implementing it in an application at this development stage. However, I have tried to create an overlay using jQuery but I've scrapped every attempt as I can't seem to make it all come together. My main problem is preventing the submission when the user incorrectly types a password or cancels the overlay. Desired Flow Persistant Login Sensitive Page Submit Password Confirmation Overlay [Continue Submit | (Cancel | Incorrect] I have already created JavaScript code to encrypt the password to be sent in a parameter, but all I need now is a method of controlling the overlay and how best to use Ajax for this purpose. Please ignore the fact that this is a J2EE web application when answering as it is irrelevant really. Thanks in advance, Alasdair

  • Running a GWT application (including Applets) inside an IFRAME from an ASP.NET 3.5 app?

    - by Jay Stevens
    We are looking at integrating a full-blown GWT (Google Web Toolkit 2.0) application with an existing ASP.NET 3.5 application. My first gut reaction is that this is a horrible frankenstein idea. However, the customer has insisted that we use this application developed by a third-party. I have almost NO CONTROL over the development of the GWT app. My first thought is to actually attempt to embed this in an iFrame. Because GWT is running under Tomcat/Jakarta, it is hosted on a different server from the .NET app so the iFrame src will be to a URL on the other machine. I need to utilize our own ASP.NET authorization scheme to restrict access to the embedded GWT application. The GWT app also uses embedded java applets, which don't seem to be working right now inside the iframe. The GWT app makes calls to a backend server (using GWT-RPC?). Any major problems with this approach that anyone can see? Will GWT work on an iframe while hosted on a different machine? NOTE: SIMPLY ADDING A DIV WITH THE SAME NAME DOES NOT WORK FOR THIS!

  • Continuous Integration with 64-bit Sharepoint and TFS 2008?

    - by Hirvox
    I've set up a 64-bit TFS 2008 build server with Sharepoint, continuous integration and out-of-the-box MSTest. Unit tests for plain business logic classes run just fine and test results are published into TFS. However, any test that uses Sharepoint's API fails horribly, SPFarm.Local returning null and so on. Is there a way to fix this? The tests run fine in an otherwise identical 32-bit development environment (Windows Server 2008 under Hyper-V, Sharepoint patched up to June 2009 cumulative update) from both Visual Studio and command line, so the problem is not about improper use of SPContext.Current or any other part of the API that needs to be run in a web server context. I've ruled out permissions issues, because the build agent account can deploy the solution and create site collections just fine with stsadm. The next culprit could be that the unit tests were being run with a 32-bit process, which couldn't access the 64-bit Sharepoint API properly. I tried a workaround, but it has the side effect of disabling TFS support in MSTest. Do I have to wait for 2010 versions of MS tools (and hope for the best) or is there a third-party test framework available that runs natively in 64 bit and can publish test results into TFS 2008?

  • rake task via cron problem loading rubygems

    - by Matenia Rossides
    I have managed to get a cron job to run a rake task by doing the following: cd /home/myusername/approotlocation/ && /usr/bin/rake sendnewsletter RAILS_ENV=development i have checked with which ruby and which rake to make sure the paths are correct (from bash) the job looks like it wants to run as i get the following email from the cron daemon when it completes Missing these required gems: chronic whenever searchlogic adzap-ar_mailer twitter gdata bitly ruby-recaptcha You're running: ruby 1.8.7.22 at /usr/bin/ruby rubygems 1.3.5 at /home/myusername/gems, /usr/lib/ruby/gems/1.8 Run `rake gems:install` to install the missing gems. (in /home/myusername/approotlocation) my custom rake file within lib/tasks is as follows: task :sendnewsletter => :environment do require 'rubygems' require 'chronic' require 'whenever' require 'searchlogic' require 'adzap-ar_mailer' require 'twitter' require 'gdata' require 'bitly' require 'ruby-recaptcha' @recipients = Subscription.all(:conditions => {:active => true}) for user in @recipients Email.send_later(:deliver_send_newsletter,user) end end with or without the require items, it still gives me the same error ... can anyone shed some light on this? or alternatively advise me on how to make a custom file within the script directory that will run this function (I already have a cron job working that will run and process all my delayed_jobs. Cheers!
