  • What are the best uses for each programming language?

    - by VirtuosiMedia
    I come from a web developer background, so I'm fairly familiar with PHP and JavaScript, but I'd eventually like to branch out into other languages. At this point, I don't have a particular direction or platform that I'm leaning toward as far as learning a new language or what I would use it for, but I would like to learn a little bit more about programming languages in general and what each one is used for. I've often heard (and I agree) that you should use the right tool for the job, so what jobs are each programming language best suited for? Edit: If you've worked with some of the newer or more obscure languages, please share for those as well.

  • PHP - Looking for an HTML Generator/Manager

    - by John Himmelman
    I'm trying to find a tool that I can use to generate markup programatically (non-irl word). Here is an example of what I'm trying to accomplish in pseudo-code... $htmlDoc = new HTML_Document(); $htmlDoc->setTitle('Cool Title'); $htmlDoc->addJs('some_js_file.js'); $htmlDoc->addStylesheet('some_css_file.css'); $divElement = new HTML_Element_Div(); $htmlDoc->append('body', $divElement); $output = $htmlDoc->generate(); What is the best tool for this?

  • Is there a nice XSL stylesheet for client-side DocBook rendering?

    - by Steven Huwig
    I want the DocBook documents in my SVN repository to look nice if someone looks at them in a web browser. I've started to write a CSS stylesheet, but I think that it will have significant limitations -- particularly ones regarding hyperlinks. There is a large body of DocBook XSL stylesheets at the DocBook site , but they don't seem to be appropriate for browser rendering. I don't want to generate static documents and put them into SVN. I want them to be basically readable for other developers without much hassle. I could write my own browser-appropriate XSL stylesheet to convert DocBook to HTML, but it seems like someone else must have already done this. I just don't know where to find it.

  • Is there a DRMAA Java library that works with Torque/PBS?

    - by dondondon
    Does anybody know a Java implementation of the DRMAA-API that is known to work with PBS/Torque cluster software? The background behind this: I would like to submit jobs to a newly set-up linux cluster from java using a DRMAA compliant API. The cluster is managed by PBS/Torque. Torque includes PBS DRMAA 1.0 library for Torque/PBS that contains a DRMA-C binding and provides in libdrmaa.so and .a binaries. I know that Sun grid engine includes a drmaa.jar providing a Java-DRMAA API. In fact I opted to use SGE but it was decided to try PBS first. The theory behind that decision was: 'DRMAA is a standard and therefore a Java API needs only a standards compliant drmaa-c binding.' However, I couldn't find such 'general DRMAA-C-java API' and now assume that this assumption is wrong and that the Java libraries are engine specific. Are we stuck here? Any comments appreciated.

  • Places to start for system programmer transitioning to web programming

    - by Sean Ochoa
    So here's where I'm coming from: My background is in C#, C++, VB Script, php, javascript, PowerShell, T-SQL, and VB 6. I have some experience with python, and a brief introduction to Ruby On Rails. At work, we're transitioning to a web based UI in the next year or so, but in asp.net & SilverLight. I would like to, if possible, learn more open source web technologies on the side. And, hopefully, in a year and a half or so, I would like to transition to a more open source web technology position. I found that I do really like python, but I'm open to pretty much anything. And yes, I do know Linux (ubuntu and gentoo), as well. And, here's my question: What technologies, frameworks, IDEs, or systems should I be highly proficient in to become a prime candidate for a position doing web application development using non-Microsoft technologies?

  • Computer science advances in past 5 years

    - by Doug Stanhope
    I don't have a computer science background and only have a rudimentary knowledge of what CS is all about. However, I wonder, what are the most significant CS advances of -say- the last five years. To give you an idea of how clueless I am, I couldn't name one of these advances. But, please don't spare me all the gory details. I'm not looking for an education in CS or a story about the history of CS. As far as this question is concerned: only the past five years matter! :-)

  • what is a data serialization system?

    - by Yang
    according to Apache AVRO project, "Avro is a serialization system". By saying data serialization system, does it mean that avro is a product or api? also, I am not quit sure about what a data serialization system is? for now, my understanding is that it is a protocol that defines how data object is passed over the network. Can anyone help explain it in an intuitive way that it is easier for people with limited distributed computing background to understand? Thanks in advance!

  • Clustering and DB Replication in virtualized (and cloud) environments

    - by devdude
    Both replication and clustering are terms for servers setups with physical (real) servers, usually implemented on a DB or AS level. Now the question: In a virtualized environment with "easy" scalable servers (touching clustering) and a higher availability (DB replication) through the means of high availability of the virtual server by the cloudserver provider, do we really need replication and clustering (as in covering the problems of traditional servers) ? Question is asked from a soultion/application provider viewpoint. Please exclude the need of replication with a business requirement background, eg. the need to replicate a DB at 2 different geographical locations to ensure performance and data. Thanks for your insights !

  • Cocoa Touch - Display an Activity Indicator while loading a UITabBar View

    - by Aurum Aquila
    I have a UITabBar Application with two views that load large amounts of data from the web in their "viewWillAppear" methods. I want to show a progress bar or an activity indicator while this data is being retrieved, to make sure the user knows the app isn't frozen. I am aware that this has been asked before. I simply need some clarification on what seems to be a rather good solution. I have implimented the code in the example. The question's original asker later solved their problem, by putting the retrieval of data into another "thread". I understand the concept of threads, but I do not know how I would impliment this. With research, I have found that I need to move all of my heavy data retrieval into a background thread, as all of the UI updating occurs in the main thread. If one would be so kind as to provide an example for me, I would be very appreciative. I can provide parts of my existing code as necessary.

  • How to retrieve a style's value in javascript?

    - by stan
    I am looking for a way to retrieve the style from an element that has a style set upon it by the style tag. <style> #box {width: 100px;} </style> In the body <div id="box"></div> I'm looking for straight javascript without the use of libraries. I tried the following, but keep receiving blanks: alert (document.getElementById("box").style.width); alert (document.getElementById("box").style.getPropertyValue("width")); I noticed that I'm only able to use the above if I have set the style using javascript, but unable to with the style tags.

  • Excel 2003 VSTO convert to PDF

    - by KClough
    I have an excel workbook vsto solution that needs to generate a pdf copy of one of its sheets as output. I have a license for abcdpdf .net and tried outputting to html, then using abcpdf to convert the html to pdf, but the excel html markup tries to emulate excel with all 4 worksheets with horrible markup. It also messes up the colors (silver background across entire workbook). Any suggestions? Here is the code I'm currently using to generate the html file: FileInfo excelDoc = new FileInfo(Globals.ThisWorkbook.Path + @"\Document.html"); Globals.Sheet2.SaveAs(excelDoc.FullName, Excel.XlFileFormat.xlHtml, missing, missing, false, false, Excel.XlSaveAsAccessMode.xlNoChange, missing, missing, missing); If I hack away some of the html header tags manually, I can get abcdpf to accept it, but the formatting is a bit off and this solution seems sub optimal. Thanks in advance.

  • Which thread invokes SensorEventListener.onSensorChanged

    - by Christoph Heindl
    From my records it seems that SensorEventListener.onSensorChanged callback is called by the same thread that registered the callback. I.e there must be some message-queue synchronization going on in the background which allows the activitys UI-Thread to handle the callbacks. That leads to my question: Is there a need to synchronize SensorEventListener.onSensorChanged with the activitys UI-thread, assuming that the activitys UI-thread registered the SensorEventListener? I cannot find any documentation references, but can see various examples calling invalidate() unsychronized or synchronize the entire callback. I used something along the lines of Log.i(TAG, "" + Thread.currentThread().getId()); to retrieve threading information. I'm running android 2.1 update1. Best regards, Christoph

  • Android VideoView plays 2 videos at the same time

    - by evosoft
    I ma trying to play a videoview on top of another video view. the first video view is paused, while the second is playing. It appears to work but no second video appears on he screen (though I hear the audio and see the controls that would normally appear on top). I am assuming this is some sort of Zorder issue. Any thoughts. By the way, I have no problem displaying other views on top of the main video view and having the video fill the background.

  • Not able to override CSS within IFrame

    - by Madhur Ahuja
    I am using disqus comments for my jekyll blog with some CSS styles overriden in my stylesheet and used to work perfectly. Recently, disqus has introduced a new UI for their comments system which has completely broken the font colors. Since my site has dark background, I am trying to apply styles based on new disqus HTML structure generated. However, it seems that none of my styles get applied. It seems that is because disqus is loaded within iframe. Any ideas how can I fix the font colors. Example of the post: http://www.madhur.co.in/blog/2012/03/27/codeplexmovegit.html UPDATE Based on this question How to apply CSS to iFrame? it seems that you cannot style a child IFrame cross domain. I am wondering how it used to work earlier. Disqus even has documentation on it http://docs.disqus.com/help/69/

  • Usage of closures with multiple arguments in swift

    - by Nilzone-
    This question is largely based on this one: Link The main difference being that I want to pass in arguments to the closure as well. Say I have something like this: func someFunctionThatTakesAClosure(completionClosure: (venues: Dictionary<String, AnyObject>, error: NSError) -> ()) { // function body goes here var error: NSError? let responseDictionary: Dictionary<String, AnyObject> = ["test" : "test2"] completionClosure(venues: responseDictionary, error: error!) } No error here. But when I call this function in my main view controller I have tried several ways but all of the result in different errors: venueService.someFunctionThatTakesAClosure(completionClosure(venues: Dictionary<String, AnyObject>, error: NSError){ }) or like this: venueService.someFunctionThatTakesAClosure((venues: Dictionary<String, AnyObject>, error: NSError){ }) or even like this: venueService.someFunctionThatTakesAClosure(completionClosure: (venues: Dictionary<String, AnyObject>, error: NSError) -> (){ }); I'm probably just way tired, but any help would be greatly appreciated!

  • Possible to use a .dll on Linux

    - by random_hero
    Question: Is it possible to compile a program on linux using a .dll file? Where this is going: This .dll will be used to write a php extension to some proprietary software from a third party. Background and Research: I have been given a library called proprietary.lib. I was curious, as I have never seen the .lib extension before, so I typed: file proprietary.lib The output was: proprietary.lib: current ar archive I did some research and found that ar is more-or-less tar (and in fact, I guess tar has since replaced ar in most *nix environments). Upon inspecting the ar manpage, I saw the t option, which displays a table listing of the contents of that archive. Cool. So I type: ar t proprietary.lib And get: proprietary.dll proprietary.dll ... (snip X lines) ...

  • http response to GET request - working in FF not Chromium

    - by Tyler
    For fun I'm trying to write a very simple server in C. When I send this response to Firefox it prints out the body "hello, world" but with Chromium it gives me a Error 100 (net::ERR_CONNECTION_CLOSED): Unknown error. This, I believe, is the relevant code: char *response = "HTTP/1.0 200 OK\r\nVary: Accept-Encoding, Accept-Language\r\nConnection: Close\r\nContent-Type: text/plain\r\nContent-Length:20\r\n\r\nhello, world"; if(send(new_fd, response, strlen(response), 0) == strlen(response)) { printf("sent\n"); }; close(new_fd); What am I missing?

  • How do I export and import application services with say MEF?

    - by John Leidegren
    I'm working with MEF right now, but the answer I'm looking for probably is irrelevant to MEF -- it's all dependency injection -- I'm just using MEF terminology as an example here. Short background story, I read this article over at MSDN with focus on Composite Applications In this figure there's three things, the shell, the application services and the modules. So that's a composite application. What I don't fully get is the application services part. What's the service, what does it look like? How do you expose a service through a module and how do you consume a service from a different module? I'd really like to see some neat small code examples, nothing fancy but something to illustrate how all this comes to life (the application services part).
