  • Can't read .cso files but I can read their .hlsl versions?

    - by Jader J Rivera
    Well I've been trying to read a .cso file to use as a shader for a DirectX program I'm currently making. Problem is no matter how I implemented a way to read the file it never worked. And after fidgeting around I discover that it's only the .cso files I can't read. I can read anything else (which means it works) even their .hlsl files. Which is strange because the .hlsl (high level shader language) files are supposed to turn into .cso (compiled shader object) files. What I'm currently doing is: vector<byte> Read(string File){ vector<byte> Text; fstream file(File, ios::in | ios::ate | ios::binary); if(file.is_open()){ Text.resize(file.tellg()); file.seekg(0 , ios::beg); file.read(reinterpret_cast<char*>(&Text[0]), Text.size()); file.close(); } return Text; }; If I then implement it. Read("VertexShader.hlsl"); //Works Read("VertexShader.cso"); //Doesn't Works?!?! And I need the .cso version of the shader to draw my sexy triangles. Without it my life and application will never continue and I have no idea what could be wrong. (I've also asked this at stack overflow but still no answers.)

  • Why does key-based ssh fail even after setting up the authorized_keys file on the remote host?

    - by Brad Grissom
    These details don't matter but I am on a Ubuntu 12.04 machine and I want to ssh into my RaspberryPi without a password. I followed the standard procedure for setting up ssh without a password: local $ ssh-keygen -t rsa (hit enter for defaults to the questions) local $ scp ~/.ssh/id_rsa.pub matt@raspihost:~/.ssh/authorized_keys I logged onto the raspihost and checked all my permissions on ~/.ssh/ and on the authorized_keys file itself. It was still not working!

  • .pam_environment in kerberized nfs4 home directory

    - by Paul Stoever
    How can I get pam_env to read the user's .pam_environment file, if the user's file is located in a kerberized NFS4 mount? The file and directory permissions for the .pam_environment file are set in a way, that allows the local root to read the file. Reading .pam_environment only fails on the first login. Subsequent logins successfully read the file. The client uses Ubuntu 12.04 Desktop, NFS/Kerberos server is 12.04 Server. The Kerberos/NFS4 stuff works with exception of this. From /var/log/auth for first login: ... lightdm: pam_krb5(lightdm:auth): user USERNAME authenticated as USERNAME@REALM lightdm: pam_unix(lightdm:session): session closed for user lightdm lightdm: pam_env(lightdm:setcred): Unable to open config file: USERHOME/.pam_environment: Permission denied lightdm: pam_env(lightdm:setcred): Unable to open config file: USERHOME/.pam_environment: Permission denied lightdm: pam_unix(lightdm:session): session opened for user USERNAME by (uid=0) ...

  • How can I find out a file's path in the text encoding used by PosteRazor?

    - by ændrük
    PosteRazor uses an apparently outdated GUI that is incapable of properly displaying my filenames: For the sake of convenience, I want to be able to open any file in PosteRazor by copying and pasting its path from Nautilus. This works in other applications, but sadly, PosteRazor in unable to understand the path: How can I convert the path that Nautilus generates into a text encoding that is compatible with PosteRazor?

  • How do you splice out a part of an xvid encoded avi file, with ffmpeg? (no problems with other files

    - by yegor
    Im using the following command, which works for most files, except what seems to be xvid encoded ones /usr/bin/ffmpeg -sameq -i file.avi -ss 00:01:00 -t 00:00:30 -ac 2 -r 25 -copyts output.avi So this should basically splice out 30 seconds of video + audio, starting from 1 minute mark. It does START encoding at the 00:01:00 mark but it goes all the way to the end of the file for some reason, ignoring that I want just 30 seconds. The output looks like this.

  • Using local repository with vmbuilder and https

However this server will be providing https access only to the repos, the http is only temporarily open. This might be due to the certificate not being valid on the https (since it's self signed) or due to the fact that vmbuilder doesn't support https? In either case how can i get this to work? (If it's the case of the invalid certificate I don't mind ignoring any checks)

  • Restore Failure from Ubuntu One

  • How can I write byte[] to socket outputstream and specify the end of file?

    - by Christopher Francisco
    I've googled 2 days straight and I can't find how to do this. I have an open stream between client and server, and client will send a JSON string (encrypted to bytes) to the server each 3 to 5 seconds. How can I write to the Socket OutputStream so that I can read each JSON string in the server. I'm guessing I need to specify some kind of end of file or something, but can't find any info on how to achieve this.

  • How to integrate ubuntu one in pcmanfm (Lubuntu file manager)?

    - by mac
    I have installed ubuntu-one on a Lubuntu machine and indeed the file syncing works for all the folder that are shared. My problem is that while on my ubuntu machine I can right click a folder and mark it as shared, I could not find a way to do the same under pcmanfm. The only workaround I was able to find is to use the daemon via command-line: u1sdtool --create-folder . which works but is kind of clumsy.... any way to integrate in the GUI?

  • Where can I get the Natty kernel .config file?

    - by Oli
    I'm using Maverick with the latest available kernels on kernel.org and building them myself. Until now I've been basing my configuration off the stock Maverick kernel and accepting the make oldconfig defaults. I've been doing this for 3 major releases now so I figure I'm starting to slip behind the current "standard". I would like to re-base my kernels off the new Natty .config file. Is this available somewhere online or do I have to download the whole kernel package and extract it?

  • Specifying and applying broad changes to a program

    - by Victor Nicollet
    How do you handle incomplete feature requests, when the ones asking for the feature cannot possibly write a complete request? Consider an imaginary situation. You are a tech lead working on a piece of software that revolves around managing profiles (maybe they're contacts in a CRM-type application, or employees in an HR application), with many operations being directly or indirectly performed on those profiles — edit fields, add comments, attach documents, send e-mail... The higher-ups decide that a lock functionality should be added whereby a profile can be locked to prevent anyone else from doing any operations on it until it's unlocked — this feature would be used by security agents to prevent anyone from touching a profile pending a security audit. Obviously, such a feature interacts with many other existing features related to profiles. For example: Can one add a comment to a locked profile? Can one see e-mails that were sent by the system to the owner of a locked profile? Can one see who recently edited a locked profile? If an e-mail was in the process of being sent when the lock happened, is the e-mail sending canceled, delayed or performed as if nothing happened? If I just changed a profile and click the "cancel" link on the confirmation, does the lock prevent the cancel or does it still go through? In all of these cases, how do I tell the user that a lock is in place? Depending on the software, there could be hundreds of such interactions, and each interaction requires a decision — is the lock going to apply and if it does, how will it be displayed to the user? And the higher-ups asking for the feature probably only see a small fraction of these, so you will probably have a lot of questions coming up while you are working on the feature. How would you and your team handle this? Would you expect the higher-ups to come up with a complete description of all cases where the lock should apply (and how), and treat all other cases as if the lock did not exist? Would you try to determine all potential interactions based on existing specifications and code, list them and ask the higher-ups to make a decision on all those where the decision is not obvious? Would you just start working and ask questions as they come up? Would you try to change their minds and settle on a more easily described feature with similar effects? The information about existing features is, as I understand it, in the code — how do you bridge the gap between the decision-makers and that information they cannot access?

  • Why am I getting such slow file transfer performance?

    - by kingdango
    Copying 4GB from a USB flash drive to my Linux partition. The flash drive is NTFS formatted (I believe, it's Windows formatted). The transfer is incredibly slow and blocks the computer frequently causing lag and hanging applications. My transfer rate is 1.2 MB/sec and that is the max it has hit when I let the File Operations window have focus. Why is this so slow under Ubuntu and significantly faster in Win 7?

  • Which VCS is efficient for storing small changes to big text files?

    - by MiguelM
    A government agency publishes a text file with thousands of records. The entire file is about 60MB. Every day the file has about 60 new or changed records. We need to validate some info against that file, and for auditing purposes, we may need to recover the file as it was in certain date. I thought I could use a VCS to store the file using git, but I understand git stores the entire text file gzipped, so the 60BM file will still need about 30MB to store everyday version. I wonder if one of the free VCS stores only diff/patch files.

  • Is the using of dirname(__FILE__) a good practice?

    looking at the code of Joomla I see that in the first line of the index, it defines the base path of installation with the dirname(FILE) is this a font of possible risk for the site, I mean if a non controlled error message show the internal path of the Joomla directory, because of, for example a failed include, can it be used to perform some kind of attack to the site ? If yes, is it convenient to use this function ? Any idea is welcome. Thanks
