  • Using Session Bean provided data on JSF welcome page

    - by takachgeza
    I use JSF managed beans calling EJB methods that are provide data from database. I want to use some data already on the welcome page of the application. What is the best solution for it? EJBs are injected into JSF managed beans and it looks like the injection is done after executing the constructor. So I am not able to call EJB methods in the constructor. The normal place for EJB call is in the JSF action methods but how to call such a method prior to loding the first page of the application? A possible solution would be to call the EJB method conditionally in a getter that is used on the welcome page, for example: public List getProductList(){ if (this.productList == null) this.productList = myEJB.getProductList(); return this.productList; } Is there any better solution? For example, in some config file?

  • What web based programming environments exist to learn on?

    - by jjclarkson
    I loved appjet (the programming environment) before it was taken over by Google. What other web based complete programming environments are out there? Which one do you think is best for starting to do real world coding the fastest? I really think coding from your browser will make programming more accessible to the public. Are there any out there that use a vim style, (e.g. jsvi) in combination with free server side hosting? The last time I looked at Bespin it was a little green. Are there others?

  • iPhone+Quartz+OpenGL. What is the correct way for Quartz and OpenGL to play nice together regarding

    - by dugla
    So we know the CoreGraphics/Quartz imaging model is based on pre-multiplied alpha. We also know that OpenGL blending is based on un-premultiplied alpha. What is the best practice to avoid head explosion when doing blending with textures that are derived from pre-multiplied alpha imagery (PNG files generated in Photoshop with pre-multiplied alpha). Given the apples/oranges mish mash of Quartz and OpenGL, what is the correct glBlendFunc for doing the fundamental Porter/Duff "over" operation? Typical example: A simple paint program. Brush shapes are texture-map patterns created from pre-multiplied alpha rgba images. Paint color is specified via glColor4(...) with the alpha channel used to control paint transparency. GL_MODULATE is used so the brush texture multiplies the (translucent) paint color to blend the color into the canvas. Problem: The texture is premult. The color is not. What is the correct way to handle this fundamental inconsistency? Thanks, Doug

  • How to stop ReSharper from showing error on a lambda expression where Action is expected?

    - by carlmon
    In Silverlight, System.Windows.Threading's Dispatcher.BeginInvoke() takes an Action<T> or a delegate to invoke. .NET allows me to pass just the lambda expression. but ReSharper sees it as an error, saying "Cannot resolve method 'BeginInvoke(lambda expression)'": Dispatcher.BeginInvoke(() => { DoSomething(); }) The error goes away if I explicitly create the Action around the expression like this: Dispatcher.BeginInvoke(new Action<object>(o => { DoSomething(); })); I prefer the least amount of code in this case for the best readability. Is there a way to disable this specific ReSharper error notification? I tried some of the options, but could not find it. Thanks, Carl

  • Named semaphores in Python?

    - by Boaz
    Hi, I have a script in python which uses a resource which can not be used by more than a certain amount of concurrent scripts running. Classically, this would be solved by a named semaphores but I can not find those in the documentation of the multiprocessing module or threading . Am I missing something or are named semaphores not implemented / exposed by Python? and more importantly, if the answer is no, what is the best way to emulate one? Thanks, Boaz PS. For reasons which are not so relevant to this question, I can not aggregate the task to a continuously running process/daemon or work with spawned processed - both of which, it seems, would have worked with the python API.

  • Should I trust Redis for data integrity?

    - by Jiaji
    In my current project, I have PostgreSQL as my master DB, and Redis as kind of a slave, e.g., when some user adds another as a friend, first the relationship will be stored in PostgreSQL and then a friend list in Redis will be updated. When some user's friend list is requested, it will be pulled out of Redis instead of PostgreSQL. The question is: when I update the friend list in Redis, should I get a fresh copy outof PostgreSQL, and replace the old list in Redis with the new one or should I keep the old list and simply SADD the userid into the list? The latter is of course best for performance, but intuitively the former does a better job in keep the data integrity? And if something like Celery is used, is the second method worth the risk?

  • Launch Reporting Services Reports from .Net Code

    - by Jeff
    What is the best way to launch reporting services reports from .Net code? One method would be to dynamically build a URL and launch a browser. Something like this: http://server/ReportServer/Pages/ReportViewer.aspx?%2fReport+Directory%2fReport%20Name&FirstParameter=1,2,3&SecondParameter=8/30/2009&rs%3aCommand=Render I don't like how it creates a dependency on the specific URL--especially report parameters which are very likely to change. Is there a better way? The reports I want to link to are in several reporting services projects hosted on one (eventually two) servers.

  • How can you toggle between two sets of values per data series in flot?

    - by Jedidja
    flot has built-in support for multiple data series (sample code) and also dual-axis (sample code). Assuming multiple data series (water, electricity, etc) that each have an amount (usage) and a dollar value (charge for that usage), what would the best way be to to use flot to display either the amount or dollar values for all the data series, while still supporting toggling display for each individual series? The idea is to send down all the data in one GET request and then let the client take care of everything else in Javascript. Ideally we could use triplets somehow {date, amount, charge}, and then possibly split that into two arrays for flot.

  • Can UMDF drivers be packaged/shipped via WiX?

    - by Rafael Rivera
    Howdy Internets: I put together a WiX 3.0 package, utilizing the DIFx extensions, with the intentions to install a Windows 7 Sensor (UMDF driver). During installation, DIFXAPP logged "No matching devices found in INF" and simply threw the driver into storage. I read I'm to populate my INF with an appropriate DriverPackageType, but according to MSDN's enumerated list, nothing fits. Is UMDF driver installation a supported scenario? If not, what's the best practice for using WiX to install such drivers? Disassembling the DIfx extension shows intent to support Co-installer packages, I have yet to try 3.5 beta.

  • How do I find/make programming friends?

    - by Anton
    I recently got my first programming internship and was extremely excited to finally be able to talk with and interact with fellow programmers. I had this assumption that I would find a bunch of like minded individuals who enjoyed programming and other aspects of geek culture. Unfortunately, I find myself working with normal people who program for a living and never discuss or show interest in programming outside of their work. It is incredibly disappointing, because I do think one of the best ways to progress in life and as a programmer is to talk about what you enjoy with others and to build bonds with people who enjoy similar things. So how do I go about finding/making programmer friends?

  • Embedding Youtube Videos on user's wall with the Javascript API

    - by dragonmantank
    I'm attempting to embed a Youtube video on a user's wall using the Javascript API. I've poured over a bunch of different tutorials and came up with this: var data = { method: 'feed', link: current_video_url, // Link to the vide on our site source: current_video_src, // Link to the Youtube video, http://youtube.com/v/[hash] picture: current_picture_url, // Thumbnail from youtube title: current_video_title, // Title from our page caption: current_video_description // Text from our page } FB.ui(data); Running the Facebook Debugger shows that the current_video_url link is being properly parsed for OG tags and is available as an embedded video. I ran a debugger and all the variables are being properly set in the data variable. This worked fine for about 2 days, and then we pushed the site live. We set up a new AppID in Facebook but now all the videos are just thumbnails instead of being embedded in the user's wall. I thought maybe this is a problem with the live site but now the dev site is broken too. What's the best way to get this to work consistently?

  • Running Script before/after Variables declared?

    - by Sam
    Hi folks. As i understand javascript .js files are best to put all the way at the bottom of html pages, to speed up loading of rest of page. Advised by Yslow(Yahoo) and Page Speed(google). Now, when in the middle of page some thing RUNS a javascript script, in Internet Explorer, i see a small warning message saying that the element is: Uncaught ReferenceError: SWFObject is not defined When i put my all.js file in the had, the error goes away but page load slows doen. What to do? Actually, i remember it was the same with php variables. If i RUN php but the variable comes later, then it just doesnt work. must define the variable first, for it to run. How to make this workflow better, in case of php scripts? and in case of javsscripts? Thanks!

  • Convert a sequence of sequences to a dictionary and vice-versa

    - by louis
    One way to manually persist a dictionary to a database is to flatten it into a sequence of sequences and pass the sequence as an argument to cursor.executemany(). The opposite is also useful, i.e. reading rows from a database and turning them into dictionaries for later use. What's the best way to go from myseq to mydict and from mydict to myseq? >>> myseq = ((0,1,2,3), (4,5,6,7), (8,9,10,11)) >>> mydict = {0: (1, 2, 3), 8: (9, 10, 11), 4: (5, 6, 7)}

  • NDIS or TDI for packet redirection to a local proxy

    - by Enrico Detoma
    I need to develop a transparent filter to redirect outgoing HTTP packets to a local proxy, to do transparent content filtering. Which is the best technology to do it, TDI or NDIS IM? My main constraint is to avoid conflicts with antivirus software, which also do some kind of packet redirection to inspect HTTP content (I don't know whether antivirus programs use TDI, NDIS IM, or both). Rather than writing the driver myself, actually, I'm also considering two commercial SDKs for packet filtering/modification: one uses a TDI driver while the other uses a NDIS IM driver, so that's the origin of my question (I was only aware of NDIS IM, before looking at the two SDKs).

  • How do views reduce code duplication?

    - by Debuger
    Hi! I read something like this about db views: Views are incredibly powerful and useful for one reason that stands out above all the other very good reasons. They reduce code duplication. That is, in most cases, the bottom line. If a query will be used in three or more places, then a view will drastically simplify your changes if the schema or query parameters change. I once had to edit 22 stored procedures to change some query logic. If the original architecture had utilized views, then I would have had only three changes. Can anyone explain to me how it works, and maybe give me some examples? Best regards!

  • Implementing Read Only view in Winform App

    - by Refracted Paladin
    I have an in house winform app for viewing, editing, and inserting member data. There are about 40 sepertate form pages that they use to manipulate different portions of the data. My question is this; What is the best way of implementing a read only view for a form page? My thoughts were to cycle through the controls setting Enabled = False or leave them be but not allow any data changes(no Save Button etc) unless it is "unlocked". I am curious how others handle this with WinForm apps?

  • Looking for Suggestion on Multi-Consumer Service Development

    - by DaveDev
    How would I model a system that needs to be able to provide content in a format that would be consumable by iphone, Android or web browser (or whatever). All a new consumer would have to do is build a UI with rules on how to handle the data. I'm thinking something RESTful returning JSON or something. I'm really looking for suggestions on the kinds of things I'd need to learn in order to be able to implement a system on this scale. As an ASP.NET MVC developer, would that be the best framework/archetectrue to go with? Thanks

  • Accessing a module's action rendered output

    - by Flavius
    Hi. I'm writing an "Account" module which should take care of everything about accounts: registration, login/logout, user administration, password recovery, account activation, etc. So I thought it would be best to reuse whatever the module's DefaultController::actionRegister() generates to show on the main page. So my question is: how to create a new "sub request" (similar to CController::forward()) from any controller (either SiteController, read: from views/layouts/main.php, or another controller, eventually of another submodule) to a given module/controller/action? I've tried with $this-forward() from within my application layout without success: it shows a blank page, no error whatsoever. Thanks

  • image processing toolbox in matlab

    - by yasuhiro89
    I've got a specific question and a related more general one... Why does imextendedmax() not give for example 9 in A(3,3) as a max? Generally... what is the best way for finding multiple maxes/peaks? The nice thing about imextended max is it allows a threshold where presumably everything under that threshold is not counted whereas imregionalmax and findpeaks are more general, less effective. A=round(rand(5)*10) A = 1 5 4 8 3 5 1 8 8 3 9 3 9 1 2 9 7 3 5 9 6 3 5 6 8 B=imextendedmax(A,8) B = 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1

  • Cross platform unicode path handling

    - by Matt Joiner
    I'm using boost::filesystem for cross-platform path manipulation, but this breaks down when calls need to be made down into interfaces I don't control that won't accept UTF-8. For example when using the Windows API, I need to convert to UTF-16, and then call the wide-string version of whatever function I was about to call, and then convert any output back to UTF-8. While the wpath, and other w* forms of many of the boost::filesystem functions help keep sanity, are there any suggestions for how best to handle this conversion to wide-string forms where needed, while maintaining consistency in my own code?

  • fastest in-memory cache for XslCompiledTransform

    - by rudnev
    I have a set of xslt stylesheet files. I need to produce the fastest performance of XslConpiledTransform, so i want to make in-memory representation of these stylesheets. I can load them to in-memory collection as IXpathNavigable on application start, and then load each IXPAthNavigable into singleton XslCompiledTransform on each request. But this works only for styleshhets without xsl:import or xsl:include. (Xsl:import is only for files). also i can load into cache many instances of XSLCompiledTransform for each template. Is it reasonable? Are there other ways? What is the best? what are another tips for improving performance MS Xslt processor?

  • How to choose the right web application framework?

    - by thenextwebguy
    http://en.wikipedia.org/wiki/Comparison_of_web_application_frameworks Since we are ambitiously aiming to be big, scalability is important, and so are globalization features. Since we are starting out without funding, price/performance and cost of licences/hardware is important. We definitely want to bring AJAX well present in the web interface. But apart from these, there's no further criteria I can come up with. I'm most experienced with C#/ASP.net, PHP and Java, in that order, but don't turn down other languages (Ruby, Python, Scala, etc.). How can we determine from the jungle of frameworks the one that suits best our goal? What other questions should we be asking ourselves? Reference material: articles, book recommendations, websites, etc.?

  • Dynamicly Inject img alt attribute jQuery

    I need some help, and before we get going, I know it is probably not best practice, but I am doing some maintenance to an existing site and need to accomplish the following for a fix. <a rel="lightbox" href="site.com" title="a generated title"><img src="site.com/img" class="post-image" alt="a long description"/></a> Okay, so I am trying to figure out how to use jQuery or any other method to take the "alt" attribute from my image, and dynamically overwrite the "title" attribute of my "a" tag. Any help would be awesome, I am kinda lost at this juncture.
