• Number range for color in GLSL

  - by kotoko

  I'm figuring out how to set a colour in a Fragment Shader. This statement gl_FragColor = (0.1,0.6,1,1); gives me white regardless of what I enter in the first 3 values. I was expecting to either give it values between 0 and 255 or 0 and 1 but neither seems to work. I can change how bright it is with values from 0 to 1 in the fourth value, but nothing for colour. Can anybody tell me if: gl_FragColor is the right variable to set. What is the range of values for the first three values. What am I currently making the Shader do.

• Globally overrride MonthNames for all instances of a specific culture

  - by Pauli Østerø

  So, i have this problem where Microsoft actually got the month names wrong for the Greenlandic culture (kl-GL). I also know that i can pass my own array of string to the DateTimeFormatInfo.MonthNames Property, but it seems like the values i specify is only used in the scope of that one CultureInfo instance. Is there a way to tell .Net that every time i have an instance of the kl-GL culture these specific monthnames should be used? I know that you can create user specific cultures, but i don't have access to some legacy code to actually change the code to use a my own userspecified culture.

• Find duplicates lines based on some delimited fileds on line

  - by Oliv

  Hello, I have a file with lines having some fields delimited by "|". I have to extract the lines that are identical based on some of the fileds (i.e. find lines which contain the same values for fields 1,2,3 12,and 13) Other fields contents have no importance for searching but the whole extracted lines have to be complete. Can anyone tell me how I can do that in KSH scripting (By exemple a script with some arguments (order dependent) that define the fileds separator and the fields which have to be compared to find duplicates lines in input file ) Thanks in advance and kind regards Oli

• What is the most efficient algorithm for reversing a String in Java?

  - by Hultner

  I am wondering which way to reverse a string in Java that is most efficient. Should I use some sort of xor method? The easy way would be to put all the chars in a stack and put them back into a string again but I doubt that's a very efficient way to do it. And please do not tell me to use some built in function in Java. I am interested in learning how to do it not to use an efficient function but not knowing why it's efficient or how it's built up.

• Qt layout problem.

  - by Lukasz Lew

  I have a following Qt code: QVBoxLayout* box = new QVBoxLayout; label = new QLabel(); // will be set later dynamically box->addWidget (label); Text in label will be set later. The problem is that when label resizes, it resizes QVBoxLayout, and it resizes other neighboring widgets. I don't want to make a label or layout fixed width. Because I want them to resize with a whole window. Is it possible to tell a widget to take all the place that it has in a layout, but not more?

• How do you force a Linux process (Java webstart App) to stop locking a Filesystem (CD-ROM) WITHOUT k

  - by Blake

  In Linux (CentOS 5.4), how do you force a process to stop locking a file system without killing the process? I am trying to get my Java Webstart Application, running locally, to eject a CD. I do not have this problem if I am just browsing through the files using a JFileChooser, but once I read the contents of a file, I can no longer eject the CD...even after removing ALL references to any files. Hitting the eject button will give the error (Title - "Cannot Eject Volume"): "An application is preventing the volume 'volume name' from being ejected" Thus, my goal is to tell the process to stop targeting the CD-ROM in order to free it up. Thank you for any help or direction!! Attempted Fix: -running the commands: sudo umount -l /media/Volume_Name //-l Lazy Unmount forces the unmount sudo eject Problem: When a new CD is inserted, it is no longer mounted automatically probably because the process is still "targeting" it.

• Dowloading a bunch of files asynchronous wait till last finished

  - by Casper Broeren

  I'm trying to download a lot of files after downloading a sql statement must insert a record. I'm using System.Net.Client to download each file synchronously, still it could be done asynchronous. There's no relation or dependency between each download. At first I just tried to use WebClient.DownloadFileAsync but that shutted the program down and killed all the download processes/threads. Second I tried to create a wait routine something like this; while (processedFiles < totalFiles) Thread.Sleep(1000) This freezed everything. So could someone tell me which aproach to take to implement this Async?

• NSMutableRequest skd problem

  - by user2164

  Hi, I am trying to make a web call with the iPhone. I have done this before and it works fine but now I can't make it work. I am trying to use the following method call which the documentation says is availble in 2.0 and later: - (void)addValue:(NSString *)value forHTTPHeaderField:(NSString *)field; I am attempting to build for version 3.2 and 4.0. NSMutableURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:30]; [request addValue:@"0" forHTTPHeaderField:@"Content-Length"]; The error that I'm getting is a runtime error that says "-[NSURLRequest addValue:forHTTPHeaderField:]: unrecognized selector sent to instance 0x600e0c0" Can anyone tell me what I am missing that stops this code from working? Thanks.

• My program is getting a false positive from AVG.

  - by JimDel

  My program is getting a false positive from AVG. Its just our companies branded version of Ultra VNC. Its only this one company that's identifying it as a virus and we've been using the same copy of that program for almost a year. I know its possible to tell this Anti Virus program the VNC client is safe, but I can't do that for all of our clients. I've tried to find a way to contact this company to see if they can do something to prevent this from happening, but I'm not getting anywhere. Has anyone who's experienced this issue with their software, found a solution? Thanks

• Facebook Like button data for a domain?

  - by mungojerie

  We make a widget for media sites and have included the Facebook Like button, so anyone who installs our widget gets the Like button on every page without having to do additional integration work. We'd like to show the site owner some basic data / analytics about Like activity... which URLs are liked, and how many times. I can't figure out if this is even available via the Graph API or FQL. If it is, I can't tell if I need an app_id and secret token for each domain or not. Any suggestions?

• Why would I see PHP NOTICE and ERRORs when running a script as a regular user, but not as root?

  - by Shawn

  As far as I can tell, there's no difference between the error reporting or message redirection between users. They both use the same PHP ini. However, when I run a script as a regular user, I get tons of NOTICES, when run as root, I get none. When starting PHP interactive mode as a regular user, I get two PHP Warnings that 'memcache' and 'xmlwriter' are already loaded; when starting as the root user, I get no warnings. I know that I should be fixing the warnings, not "making the warnings go away;" that's on the ticket. The question is, Why are the users treated differently? Why does a regular user get notices and warnings, but root does not, even if their error reporting are the same?

• @Secured not working

  - by user3640507

  I am new to spring and trying to implement Role based authorization with the help of @Secured annotation. I have a method which is specifically for ADMIN and I have written @Secured ("ROLE_ADMIN") to secure it. @Secured ("ROLE_ADMIN") public void HelloUser(String name) { System.out.println("Hello ADMIN"); } Now when I call this method by creating a class object it gets called eventhough user dont have ADMIN authority But when I dont create an object and use @autowired annotation instead then it works i.e User is not allowed to access this method. In my security.xml as well as servlet.xml I have added <global-method-security secured-annotations="enabled" /> Can some one please tell me where I am going wrong or is this the natural behaviour in spring ?

• Is this possible with OpenGL?

  - by user146780

  Basically what I'd like to do is make textured NGONS. I also want to use a tesselator (GLU) to make concave and multicontour objects. I was wondering how the texture comes into play though. I think that the tesselator will return verticies so I will add these to my array, that's fine. But my vertex array will contain more than one polygon object so then how can I tell it when to bind the texture like in immediate mode? Right now I feel stuck with one call to bind. How can this be done? Thanks

• "Reloading" Bindings in Ninject2?

  - by Michael Stum

  I'm using Ninject2 for DI and I have a Module that loads data from a config file. I wonder if there is a way to tell the Kernel or the Module to reload the config? (I can trigger that through code if needed) What worries me is the lifetime of existing objects. Say I have ITest bound to TestImpl1 in Singleton Scope and I change the config to bind ITest to TestImpl2 instead. All new requests should get TestImpl2, but the classes that already requested TestImpl1 before obviously keep it. However, what if all users of TestImpl1 are gone - will TestImpl1 be properly garbage collected and disposed in case it implements IDisposable? Or will it just be orphaned? Do I have to loop through each type and call Unbind/Bind on it? Or can I just unload the entire Module and reload it while still managing any existing object?

• Change the text of a gcc compiler error

  - by NSA

  Hello, At my company we have recently done some tricky stuff with C++ and templates, making use of some features of the compiler. When working with this code people need to take a few setup steps otherwise they get some rather cryptic compiler errors, what I would like to do is determine if there is a way to tell the compiler to inject, and or swap out the message published for an error when compiling? so that I either get a friendly message that instructs the person in conjunction with the cryptic error or instead of the cryptic error. Thank you.

• Hibernate Many-To-One Foreign Key Default 0

  - by user573648

  I have a table where the the parent object has an optional many-to-one relationship. The problem is that the table is setup to default the fkey column to 0. When selecting, using fetch="join", etc-- the default of 0 on the fkey is being used to try over and over to select from another table for the ID 0. Of course this doesn't exist, but how can I tell Hibernate to treat a value of 0 to be the same as NULL-- to not cycle through 20+ times in fetching a relationship which doesn't exist? <many-to-one name="device" lazy="false" class="Device" not-null="true" access="field" cascade="none" not-found="ignore"> <column name="DEVICEID" default="0" not-null="false"/>

• What is a simple C library for a set of integer sets?

  - by conradlee

  I've got to modify a C program and I need to include a set of unsigned integer sets. That is, I have millions of sets of integers (each of these integer sets contains between 3 and 100 integers), and I need to store these in some structure, lets call it the directory, that can in logarithmic time tell me whether a given integer set already exists in the directory. The only operations that need to be defined on the directory is lookup and insert. This would be easy in languages with built-in support for useful data structures, but I'm a foreigner to C and looking around on Google did (surprisingly) not answer my question satisfactorily. This project looks about right: http://uthash.sourceforge.net/ but I would need to come up with my own hash key generator. This is a standard, simple problem, so I hope there is a standard and simple solution.

• Python: Using `copyreg` to define reducers for types that already have reducers

  - by cool-RR

  (Keep in mind I'm working in Python 3, so a solution needs to work in Python 3.) I would like to use the copyreg module to teach Python how to pickle functions. When I tried to do it, the _Pickler object would still try to pickle functions using the save_global function. (Which doesn't work for unbound methods, and that's the motivation for doing this.) It seems like _Pickler first tries to look in its own dispatch for the type of the object that you want to pickle before looking in copyreg.dispatch_table. I'm not sure if this is intentional. Is there any way for me to tell Python to pickle functions with the reducer that I provide?
