• What happened to .fx files in D3D11?

  - by bobobobo

  It seems they completely ruined .fx file loading / parsing in D3D11. In D3D9, loading an entire effect file was D3DXCreateEffectFromFile( .. ), and you got a ID3DXEffect9, which had great methods like SetTechnique and BeginPass, making it easy to load and execute a shader with multiple techniques. Is this completely manual now in D3D11? The highest level functionality I can find is loading a SINGLE shader from an FX file using D3DX11CompileFromFile. Does anyone know if there's an easier way to load FX files and choose a technique? With the level of functionality provided in D3D11 now, it seems like you're better off just writing .hlsl files and forgetting about the whole idea of Techniques.

• vertical navigation that shows hidden submenu on click using JQuery

  - by user346602

  Hi, I am trying to make a menu that works like the one on this flash site: http://elevensix.de/ When I click "portfolio", only then to the subnavigation links reveal themselves. Right now I have only managed to get a typical vertical "reveal subnavigation on hover menu" working. What is required is that once the appropriate menu item it cicked, its submenu shows. This submenu remains revealed as the submenu items are hovered over then selected. When the submenu item is selected, the content shows, and both the menu and submenu remain visible (the selected menu and submenu item are given a distinct colour to show the navigation path). Whew. Here is my html: <div id="nav"> <ul> <li><a href="#">about</a></li> <li><a href="#">testimonials</a> <ul> <li><a href="#">testimonial1</a></li> <li><a href="#">testimonial2</a></li> <li><a href="#">testimonial3</a></li> <li><a href="#">testimonial4</a></li> </ul> </li> <li><a href="#">Services</a> <ul> <li><a href="#">services1</a></li> <li><a href="#">services2</a></li> <li><a href="#">services3</a></li> <li><a href="#">services4</a></li> </ul> </li> <li><a href="#">Gallery</a></li> <li><a href="#">Contact</a></li> </ul> </div><!--end #nav--> and here is my css: #nav { width:160px; position: relative; top: 250px; left: 20px; } #nav ul { margin:0px; padding:0px; } #nav ul li { line-height:24px; list-style:none; } #nav a { text-decoration: none; color: #9d9fa2; } #nav ul li a:hover { position:relative; color: #00aeef; } #nav ul ul { display:none; position:absolute; left:160px; top:4px; } #nav ul li:hover ul { display:block; color: #00aeef; } #nav ul ul li { width:160px; float:left; display:inline; line-height:16px; } .selected { color: #00aeef !important; } Should I be giving the submenus a class so that I can hide then show them? And where would the class be applied? To the ul? could I use the same class for both submenus? Am I wrong in how I am applying the display:none values for this purpose? Many thanks to all the clever people on here.

• Ubuntu One synching changed files

  - by Mark

  I have several folders in the Ubuntu1 folder and if I add a new file (on my PC oder my Mobile) the file shows up in the other device or in the online access. However, if I change one of the files (like a spreadsheet I change almost daily on my PC) Ubuntu1 is not updating the changed file. It is still the old file on the other devices. Doesn't Ubuntu1 sync changed files only new ones or do I have to change some settings? Could someone be so nice and help me? Thanks in advance! Mark PS: I am using Ubuntu 11.10 64 bit.

• How to Easily Share Files Between Nearby Computers

  - by Chris Hoffman

  It’s a common situation — you have several computers near each other and you want to transfer files between them. You don’t have to pull out a USB drive, nor do you have to send them over email — there are faster, easier ways. This is easier than it was in the past, as you don’t have to mess with any complicated Windows networking settings. There are lots of ways to share files, but we’ll cover some of the best.

• I see files in filezilla, but the internet denies their existance

  - by Zach L.

  I am doing some updates to a 10-year old site, and I am baffled. Everything worked great locally, so I uploaded a bunch of stuff to the server using filezilla. Within filezilla I can see all of the files, but for some reason I get a 404 when trying to view them. It seems as though (at least for the folder Im currently checking) this is happening for items which are "farther down the list" alphabetically. I tried to re-upload a file individually but it didn't change anything. Is this an indication that I hit some sort of limit with the hosting company? And if so why can I still view the files from filezilla? Please offer guidance. I am at a loss.

• Y-axis in MATLAB bar plot is hidden.

  - by Claus

  I am drawing a simple bar diagram in MATLAB. The problem is, that the value at x = 0 lets the y-axis disappear partially. Is there a way to bring the y-axis to the front instead of hiding between the y-value for x=0? Is there any option I can make sure the y-axis is always in the front?

• Extracting GPS Data from JPG files

  - by Peter W. DeBetta

  I have been very remiss in posting lately. Unfortunately, much of what I do now involves client work that I cannot post. Fortunately, someone asked me how he could get a formatted list (e.g. tab-delimited) of files with GPS data from those files. He also added the constraint that this could not be a new piece of software (company security) and had to be scriptable. I did some searching around, and found some techniques for extracting GPS data, but was unable to find a complete solution. So, I did...(read more)

• Encourage the use of markup files as documentation in enterprise [closed]

  - by linquize

  To make it eaiser to do version control and diff files of documentation, use markup files, such as HTML: html/xhtml, XML: docbook, Wiki: markdown to replace doc/docx. docx is too complex and lengthy. For html, no extra document generation required. Programmers can write html directly and end users / managers can use any web browsers to view the document. For custom XML or Wiki formats, viewers are required to view the document or converters are used to export to pdf/doc. Is such move becoming popular in enterprise context? Why or why not?

• NSTextField and hidden property

  - by jasonbogd

  Hi, I have an NSTextField that I hide when the user presses a button. I hide the text field using [textField setHidden:YES]; The problem is that is the user is typing in the text field (i.e. the text field is first responder) and the user presses the return key (which is the key equivalent for the button that hides the text field) the user can keep typing in the text field even though its not visible. How do I correctly remove a text field without actually deallocating it? Thanks.

• How to play WMV files?

  - by Isaiah Bugarin

  I tried playing a WMV file in VLC and it told me something along the lines of Unable to play WMV3 files. Unfortunately there is no way for you to fix this. When I try to open the same file in MPlayer, it tells me an Internal data stream error occurred. I finally got it to start playing in KPlayer, but it is really sketchy; it's black and white and there's a few random blue lines down the middle of the video. So is there any support for WMV3 files? P.S. the same WMV file plays fine on my PC. A different WMV file plays on Ubuntu fine.

• Folder Permissions for new partition - can't move files

  - by user292743

  I'm using Ubuntu 14.04. I used the install CD to repartition my HD by resizing /dev/sda1 and creating /dev/sda3 as a Primary Partition. I named it "Media". When I reboot from HD, when I try to move files from the home directory to the new partition, I get an error message "Error while copying. The folder “TV” cannot be copied because you do not have permissions to create it in the destination." The new partition shows up in Gparted as locked, with mount point /media/ian/Media and Label Media. I want to move my media files from the boot partition to a separate partition. Any advice?

• inheritance and hidden overloads

  - by Caspin

  The following code doesn't compile. struct A {}; struct B {}; class Base { public: virtual void method( A param ) { } virtual void method( B param ) = 0; }; class Derived : public Base { public: //using Base::method; void method( B param ) { } }; int main() { Derived derived; derived.method(A()); } The compiler can't find the overload of method() that has an A parameter. The 'fix' is to add a using declaration in the derived class. My question is why. What is the rational for a weird language rule like this? I verified the error in both GCC and Comeau, so I assume this isn't a compiler bug but a feature of the language. Comeau at least gives me this warning: "ComeauTest.c", line 10: warning: overloaded virtual function "Base::method" is only partially overridden in class "Derived" class Derived : public Base ^

• Sending files via HTTP to web service

  - by Serguei Fedorov

  I am bit frustrated at the lack of information about this online. Here is the issue: I am in charge of creating a iOS application which sends sound data back and forth between the server and the app. The Audio is in small files and thus does not need to be streamed over, but rather it can be sent. Right now, I am using a TCP server I wrote to handle applications like this. However, I want to keep the system as simple as possible and writing your own server and client sockets can get a bit complex and leaves room for crashes. Overall it slows down development because I need to account for packet structure and other things. My question is, can I write an ASPX or PHP web service that lets me pass the files back and forth through GET or POST?

• ffmpeg: cut multiple input files with seeking to one output file

  - by Josef Kufner

  I have list of video files (loaded from database), each with start and end time of requested interval: # file begin end v1.mp4 1:01 2:01 v2.mp4 3:02 3:32 v3.mp4 2:03 5:23 And I need to create single video file containing these intervals: [0:00]---v1---[2:00]---v2---[2:30]---v3---[5:50] I preffer usig ffmpeg, since it is installed on server. Caller program is written in PHP. It is easy to cut one input to one output (argument escaping removed for clarity): exec("ffmpeg -ss $begin -i $input_file -ss $begin -c copy $output_file"); I there any easier way than executing ffmpeg for each interval and then execute it once more to concatenate prepared clips together? I really do not like to have a lot of temporary files or dealing with complex process handling.

• HTG Explains: Why Deleted Files Can Be Recovered and How You Can Prevent It

  - by Chris Hoffman

  When you a delete a file, it isn’t really erased – it continues existing on your hard drive, even after you empty it from the Recycle Bin. This allows you (and other people) to recover files you’ve deleted. If you’re not careful, this will also allow other people to recover your confidential files, even if you think you’ve deleted them. This is a particularly important concern when you’re disposing of a computer or hard drive.

• Situations that require protecting files against tampering when stored on a users computer

  - by Joel

  I'm making a 'Pokémon Storage System' with a Client/Server model and as part of that I was thinking of storing an inventory file on the users computer which I do not wish to be edited except by my program. An alternative to this would be to instead to store the inventory file on the server and control it's editing by sending commands to the server but I was wondering if there are any situations which require files to be stored on a users computer where editing would be undesirable and if so how do you protect the files? I was thinking AES with some sort of checksum?

• Force Your Mac to Sort Folders on Top of Files (Windows Style)

  - by Eric Z Goodnight

  Even die-hard Mac converts have their issues with Mac OS, and one of those problems is that OS X lists folders mixed in with all other files. Here’s how to fix that in under five minutes with a clever hack. You know you’ve had that issue. You’ve dug through your files looking for that one elusive folder, and because it’s jumbled in with all the other stuff, it’s more or less impossible to find. Have no fear, with no downloads or silly plug-in software, you can finally make Mac OS behave like Windows and Linux and list those folders in the proper order.  How To Encrypt Your Cloud-Based Drive with BoxcryptorHTG Explains: Photography with Film-Based CamerasHow to Clean Your Dirty Smartphone (Without Breaking Something)

• Ubuntu 12.04 graphics crashing when GVIM opens TEX files

  - by Pdp Molniya

  I am having a little problem everytime I open GVIM to edit *.TEX files.... the menus die, windows jiggle (maximize and minimize quickly) and I get a 'internal error ' crash report from ubuntu (12.04). It says the problem is at /usr/lib/unity/unity-panel-service. Any tips on how to solve this? It might be related to the Latex package of vim (also I get this message when I open gvim (with or without TEX files) on terminal: (gvim:5915): Gnome-WARNING **: Accessibility: failed to find module 'libgail-gnome' which is needed to make this application accessible (gvim:5915): GLib-GObject-WARNING **: cannot retrieve class for invalid (unclassed) type `' Issue is independant of theme I just checked... Thanks a lot for your help! Cheers, Pedro

• Nested class with hidden constructor impossible in c#?

  - by luckyluke

  I' ve been doing some programming lately and faced an issue which i found weird in c#. (at least for me) public class Foo { //whatever public class FooSpecificCollection : List<Bar> { //implementation details } public FooSpecificCollection GetFoosStuff() { //return the collection } } I want the consumer of Foo to be able to obtain a reference to FooSpecificCollection, even perform some operations on it. Maybe even set it to some other property of Foo or smth like that, but not To be able to CREATE an instance of this class. (the only class that should be able to instatiate this collection should be Foo. Is my request really that far-fetched? I know that people way smarter defined c# but shouldn't there be such an option that a parent class can create a nested class instance but nobody else can't. So far I created a solution to make an abstract class, or interface available through the property and implement a concrete private class that is not available anywhere else. Is this a correct way to handle such a situation.?

• How to access hidden template in unnamed namespace?

  - by Johannes Schaub - litb

  Here is a tricky situation, and i wonder what ways there are to solve it namespace { template <class T> struct Template { /* ... */ }; } typedef Template<int> Template; Sadly, the Template typedef interferes with the Template template in the unnamed namespace. When you try to do Template<float> in the global scope, the compiler raises an ambiguity error between the template name and the typedef name. You don't have control over either the template name or the typedef-name. Now I want to know whether it is possible to: Create an object of the typedefed type Template (i.e Template<int>) in the global namespace. Create an object of the type Template<float> in the global namespace. You are not allowed to add anything to the unnamed namespace. Everything should be done in the global namespace. This is out of curiosity because i was wondering what tricks there are for solving such an ambiguity. It's not a practical problem i hit during daily programming.

• Limit the size of a directory by deleting old files

  - by Sulliwane

  I have a IP cam which save its recordings in a specific directory named Camera1 in my Ubuntu Server 12.04. I would like to limit the size of this folder to 5 gigs, by deleting -say once a day- the oldest files. I first checked the quota program but it doesn't seem to allow the creation of new files and deleting of the old ones. So I think the best workaround would be to run a bash script ? But I have no idea how to write it... Thank you guys !
