• Can I use/include gsdll32.dll redmonnt.dll (no modificaitons) in a commercial application for my cli

  - by scriptmaster

  Hi - I am not a license expert, however after a lot of research, I am still struggling to answer the following questions and would like to know if my assumptions are right! 1) Is it legal to include gsdll32.dll and redmonnt.dll in a commercial product? A: ? 2) Should I release any source code of the commercial app where I am using this library? A: ? 3) Is there a commercial license (a small fee that my client can pay to use these libraries) to GhostScript? A: ? 4) Whats the meaning of "although it may be distributed ("aggregated") with commercial products." in this para: http://pages.cs.wisc.edu/~ghost/doc/AFPL/8.00/New-user.htm#Commercial_use A: ? 5) What are the alternate solutions? A: ?

• Programmatically determine DPI via the browser?

  - by Brandon Pelfrey

  Hi all. I would like to programmaticaly determine the DPI of a user's display in order to show a web page at a precise number of units (centimeters/inches). I know it a weird request: it's for a visualization research project and it's kind of a control. We currently do it by having the user place a credit card to the screen and match a resizable div (via Mootools) to the real credit card, and voila we can get the DPI and display the page correctly. Can anyone think of a programmatic way to do this?

• Changing timezone without changing time in Java

  - by Martin

  Hi! I'm receiving a datetime from a SOAP webservice without timzone information. Hence, the Axis deserializer assumes UTC. However, the datetime really is in Sydney time. I've solved the problem by substracting the timezone offset: Calendar trade_date = trade.getTradeDateTime(); TimeZone est_tz = TimeZone.getTimeZone("Australia/Sydney"); long millis = trade_date.getTimeInMillis() - est_tz.getRawOffset(); trade_date.setTimeZone( est_tz ); trade_date.setTimeInMillis( millis ); However, I'm not sure if this solution also takes daylight saving into account. I think it should, because all operations are on UTC time. Any experiences with manipulating time in Java? Better ideas on how to solve this problem?

• Creating multiple markers in Google Maps using XML

  - by Jessica Stanley

  I'm almost sure this question has been asked before, but for the love of me I just can't find the answer anywhere. Basically what I want to do is create multiple markers on a custom Google Map I'm building. I already have an XML file with the coordinates (lat/lng) and title of each item. I'd like to take the data from the XML file and use it to create markers on the map. I've found how to do this using KML files and MySQL/PHP, but I need to know how to do it in Javascript. One more thing: I have a .xml file of my own, so it won't be like I'll be getting the data from a webpage because I believe (from research I've done today) that the code for that may be different. If anyone knows if this has been posted somewhere else before, could you please direct me there? I've literally been searching all day, this is my last resort. Thanks a ton!!!

• Does CodeIgniter have to load view in the final step?

  - by Peter

  I have a function function do_something() { // process $this->load->view('some_view', $data); exec('mv /path/to/folder1/*.mp3 /path/to/folder2/'); } My intention is to move files after outputting the view. But apparently it is done before rendering the view. My question is, does $this->load->view(); have to be the final step in a function? I did a little research, and seems like my question is similar to this topic. Correct?

• Run shell script using fabric and piping script text to shell's stdin

  - by Peter Lyons

  Is there a way to execute a multi-line shell script by piping it to the remote shell's standard input in fabric? Or must I always write it to the remote filesystem, then run it, then delete it? I like sending to stdin as it avoids the temporary file. If there's no fabric API (and it seems like there is not based on my research), presumably I can just use the ssh module directly. Basically I wish fabric.api.run was not limited to a 1-line command that gets passed to the shell as a command line argument, but instead would take a full multi-line script and write it to the remote shell's standard input.

• iPhone Live Video Stream Media Player

  - by happyhammer83

  I'm hoping to make an app that streams live video that has a view placed on top with labels and a button on it. From my research and testing of the http video streaming feature (available since iPhone 3.0 OS), it seems that you create a webview that points to the index html that contains the converted video stream, and this displays as a quicktime video in the app. This means that I don't have control over the Media Player that is opened. Does anyone know how you can control this? I know that the Apple's MoviePlayer sample code shows you how to place views on top of a MediaPlayer video, but how can this be done with a http live stream? Thanks in advance.

• Choosing embedded EJB 3.x container to run JEE 5 app on Tomcat

  - by grigory

  I am sorry in advance if my question sounds too generic - I am doing all preliminary research myself but nothing substitutes real experience... My goal is to port a legacy JEE application (pre-EJB 3.x) to Tomcat with embedded EJB container. My choices currently stand as follows: JBoss Embeddable EJB Apache OpenEJB OW2 Consortium EasyBeans anything else? I am expecting to use JMS (with MDBs), Session beans (stateful and stateless), JPA and I am really excited about using JSF with Seam. Now, given choices above, are there any advantages in using one or another embedded EJB provider?

• How to populate an array with recordset data

  - by Curtis Inderwiesche

  I am attempting to move data from a recordset directly into an array. I know this is possible, but specifically I want to do this in VBA as this is being done in MS Access 2003. Typically I would do something like the following to archive this: Dim vaData As Variant Dim rst As ADODB.Recordset ' Pull data into recordset code here... ' Populate the array with the whole recordset. vaData = rst.GetRows What differences exist between VB and VBA which makes this type of operation not work? What about performance concerns? Is this an "expensive" operations?

• How to build a RESTful API?

  - by Sharon Haim Pour

  Hi friends, The issue is this: I have a web application that runs on a PHP server. I'd like to build a REST api for it. I did some research and I figured out that REST api uses HTTP methods (GET, POST...) for certain URI's with an authentication key (not necessarily) and the information is presented back as a HTTP response with the info as XML or JSON (I'd rather JSON). My question is: 1. How do I, as the developer of the app, build those URI's? Do I need to write a PHP code at that URI? 2. How do I build the JSON objects to return as a response? I hope I was clear enough. Thanks!

• Self host WCF (Windows Communication Foundation) Ajax services

  I am having trouble to understand how to expose the WCF services through Javascript. Here are what I found after days of research: Exposing WCF services through Javascript but not self host: http://msdn.microsoft.com/en-us/library/bb472488.aspx In this example, it requires the creation of a .svc file <%@ServiceHost language="c#" Debug="true" Service="Microsoft.Samples.XmlAjaxService.CalculatorService" Factory="System.ServiceModel.Activation.WebServiceHostFactory" %> Self host WCF Ajax services but not exposing the services through Javascript. http://msdn.microsoft.com/en-us/library/bb943471%28v=VS.100%29.aspx Please help.

• DOM and Javascript

  - by Bob Smith

  I let a user reconfigure the location of a set of rows in a table by giving them ability to move them up and down. The changes are done by swapping nodes in the DOM. After the user has moved rows around, when I do a view source, I see the HTML in the original state (before the user made any changes). Can someone explain why that is? My understanding was when we do any DOM operations, the underlying HTML will be changed as well. EDIT: Does that mean on the server side, when attempt to get the state after user's changes, I will be able to get what I need? I am using C#/ASP.NET. Could it be because this is a HTML table (not ASP.NET Server control), that it's not maintaining the state of the changes?

• Iterating Oracle collections of objects with out exploding them

  - by Scott Bailey

  I'm using Oracle object data types to represent a timespan or period. And I've got to do a bunch of operations that involve working with collections of periods. Iterating over collections in SQL is significantly faster than in PL/SQL. CREATE TYPE PERIOD AS OBJECT ( beginning DATE, ending DATE, ... some member functions...); CREATE TYPE PERIOD_TABLE AS TABLE OF PERIOD; -- sample usage SELECT <<period object>>.contains(period2) FROM TABLE(period_table1) t The problem is that the TABLE() function explodes the objects into scalar values, and I really need the objects instead. I could use the scalar values to recreate the objects but this would incur the overhead of re-instantiating the objects. And the period is designed to be subclassed so there would be additional difficulty trying to figure out what to initialize it as. Is there another way to do this that doesn't destroy my objects?

• Is there an existing solution to the multithreaded data structure problem?

  - by thr

  I've had the need for a multi-threaded data structure that supports these claims: Allows multiple concurrent readers and writers Is sorted Is easy to reason about Fulfilling multiple readers and one writer is a lot easier, but I really would wan't to allow multiple writers. I've been doing research into this area, and I'm aware of ConcurrentSkipList (by Lea based on work by Fraser and Harris) as it's implemented in Java SE 6. I've also implemented my own version of a concurrent Skip List based on A Provably Correct Scalable Concurrent Skip List by Herlihy, Lev, Luchangco and Shavit. These two implementations are developed by people that are light years smarter then me, but I still (somewhat ashamed, because it is amazing work) have to ask the question if these are the two only viable implementations of a concurrent multi reader/writer data structures available today?

• Concise SSE and MMX instruction reference with latencies and throughput

  - by Joe

  I am trying to optimize some arithmetic by using the MMX and SSE instruction sets with inline assembly. However, I have been unable to find good references for the timings and usages of these enhanced instruction sets. Could you please help me find references that contain information about the throughput, latency, operands, and perhaps short descriptions of the instructions? So far, I have found: Intel Instruction References http://www.intel.com/Assets/PDF/manual/253666.pdf http://www.intel.com/Assets/PDF/manual/253667.pdf Intel Optimization Guide http://www.intel.com/Assets/PDF/manual/248966.pdf Timings of Integer Operations http://gmplib.org/~tege/x86-timing.pdf

• How to update individual files in a war file

  - by ziggy

  Hi guys, I am doing some research in the way i can deploy an application efficiently using a war file. What i currently do is i deliver the war file everytime there is a release. This means everytime there is a change no matter how small the change is i have to build and deliver all files that make up the application. I am thinking that maybe this is not the correct way to do this. For example if there is a change to a css file i have to rebuild the war file which will include all file. This includes recompiling all *.java files as well. In the above example, is it possible to build a war file with just the css file and deploy it to the tomcat server and have Tomcat just replace the css file and leave everything else as is?

• Android Image Getter for Larger Images

  - by y ramesh rao

  I have used all the Standard Network related code for Getting Images of about 45KB to 75KB but all are failing these methods work fine for Files of about 3-5KB size of Images. How can I achieve Downloading Image of 45 - 75KB for displaying them on an ImageView in Android for my Netowrk Operations the Things I have used are final URL url = new URL(urlString); final URLConnection conn = url.openConnection(); HttpURLConnection httpConn = (HttpURLConnection) conn; httpConn.setAllowUserInteraction(true); httpConn.setInstanceFollowRedirects(true); httpConn.setRequestMethod("GET"); httpConn.connect(); and the Second option that I have had used is:: DefaultHttpClient httpClient = new DefaultHttpClient(); HttpGet getRequest = new HttpGet(urlString); HttpResponse response = httpClient.execute(getRequest); why is this code functional for Smaller Sized Images and not for Larger Size Images. ?

• I don't understand Application Domains

  - by Jeremy Edwards

  .NET has this concept of Application Domains which from what I understand can be used to load an assembly into memory. I've done some research on Application Domains as well as go to my local book store for some additional knowledge on this subject matter but it seems very scarce. All I know that I can do with Application Domains is to load assemblies in memory and I can unload them when I want. What are the capabilities other that I have mentioned of Application Domains? Do Threads respect Application Domains boundaries? Are there any drawbacks from loading Assemblies in different Application Domains other than the main Application Domains beyond performance of communication? Links to resources that discuss Application Domains would be nice as well. I've already checked out MSDN which doesn't have that much information about them.

• What is the difference between File and FileInfo in C# ?

  - by Lilitu88

  I've been reading that the static methods of the File Class are better used to perform small and few tasks on a file like checking to see if it exists and that we should use an instance of the FileInfo Class if we are going to perform many operations on a specific file. I understand this and can simply use it that way blindly but I would like to know why is there a difference ? What is it about the way they work that make them suitable for different situations ? What is the point of having this 2 different classes that seem do the same in different ways ? It would be helpful if someone could answer at least one of this questions.

• tool for adding parentheses to equations?

  - by jedierikb

  Is there an online tool for adding parentheses to simple math equations? For example, a + b * c into a + (b * c) Those who paid more attention in math class might be able to tackle order of operations for huge equations in their head, but I could often use some help (and verification of my thinking). I often encounter other people's libraries having equations and functions I need for my code, and this would be kind of helpful for debugging and understanding. I was hoping Wolfram Alpha would do this, but the output is not easy to plug back into most programming languages e.g. a + (bc)

• Is it bad programming style to have a single, maybe common, generic exception?

  - by m0s

  Hi, so in my program I have parts where I use try catch blocks like this try { DirectoryInfo dirInfo = new DirectoryInfo(someString); //I don't know if that directory exists //I don't know if that string is valid path string... it could be anything //Some operations here } catch(Exception iDontCareWhyItFailed) { //Didn't work? great... we will say: somethings wrong, try again/next one } Of course I probably could do checks to see if the string is valid path (regex), then I would check if directory exists, then I could catch various exceptions to see why my routine failed and give more info... But in my program it's not really necessary. Now I just really need to know if this is acceptable, and what would a pro say/think about that. Thanks a lot for attention.

• Recommended way to manage persistent PHP script processes?

  - by BigglesZX

  First off - hello, this is my first Stack Overflow question so I'll try my best to communicate properly. The title of my question may be a bit ambiguous so let me expand upon it immediately: I'm planning a project which involves taking data inputs from several "streaming" APIs, Twitter being one example. I've got a basic script coded up in PHP which runs indefinitely from the command line, taking input from the Twitter streaming API and doing very basic things with it. My eventual objective is to have several such processes running (perhaps daemonized using the System Daemon PEAR class), and I would like to be able to manage them from some governing process (also a PHP script). By manage I mean basic operations such as stop/start and (most crucially) automatically restarting a process that crashes. I would appreciate any pointers on how best to approach this process management angle. Again, apologies if this question is too expansive - tips on more tightly focused lines of enquiry would be appreciated if necessary. Thanks for reading and I look forward to your answers.

• A compiler for automata theory

  - by saadtaame

  I'm designing a programming language for automata theory. My goal is to allow programmers to use machines (DFA, NFA, etc...) as units in expressions. I'm confused whether the language should be compiled, interpreted, or jit-compiled! My intuition is that compilation is a good choice, for some operations might take too much time (converting NFA's to equivalent DFA's can be expensive). Translating to x86 seems good. There is one issue however: I want the user to be able to plot machines. Any ideas?
