• Which 3D file formats support multiple animations? [on hold]

  - by Justin

  I'm working on a 3D application that uses Assimp to import 3D models with animations. Personally, I use Blender to create the models and animations. I'm having trouble exporting multiple animations, however. For example, I'd like to have an idle animation, a walk animation, a run animation, etc. So far I've tried COLLADA and DirectX without much success. The COLLADA export will include the first animation, but not any of the others. The DirectX doesn't include any animation. Which 3D file formats support multiple animations? (Preferably one that Assimp can import. Also, the Assimp website says that it doesn't support .blend files with animation, otherwise I'd just do that.)

• How i can sign and/or group a specific set of vertices in a 3D file container like OBJ ? - in Blender

  - by user827992

  I would like to export a 3D model with each part having a name or a label if you will. For example i would like to export a model of an human body and name each part in specifics vertex groups like: left hand, right hand, right foot, head, ears, ... and you got the idea; so i can have a single 3D model that i can explode in various parts if needed. If there is a better technique about how to mark vertex groups in a 3D file please share your solution. As 3D editor i use Blender.

• How can set up a file sharing server to allow remote access over a WAN?

  - by pst007x

  I want to set up a server to allow remote access over a WAN. The purpose is to allow people to remote connect and download specific files from a specified folder hosted on the server. Is there software available to achieve this, preferably with an interface so I can easily add and remove users, plus monitor who is connected at any time? I have looked around and only found terminal references, and not very clear how to set up. I have a service running on my Win server, but I am hoping to move from that to Ubuntu for my file sharing. I do not want people who access the server to have any local accounts or any access to any folder/files apart from authorised folders/files. Thanks

• C++ question on file formats and od

  - by user231536

  I have the following simple code: ofstream output("test"); output << 'a'; When I do an octal dump of the file, I get this: 0000000 000141 0000001 I can see that 000141 (in base 8) is 8 bits wide and 0000001 is probably EOF. What is the first byte of all 0's and why is it there? I know it is null is ascii but what is its purpose?

• opening a file attachment from an outlook email using clickonce and a file association

  - by MarkGr

  Hi, I have a clickonce application (VS2010, .NET 4). I have registered a file association (.task), and this all works well. If I double click a file with the .task extension on the desktop the clickonce application opens and can open the file. If I email the file however, and double click the file from within outlook, I get the open/save dialog. If I click open nothing appears to happen. If I save the file I can open it by double clicking on it. Any ideas why the file does not open from within outlook ? Thanks, Mark

• php - sort the unsorted text file and rewrite to same text file in sorted order

  - by arrgggg

  Hi, I have a question. I am in process of learning how to read/write files, but having little trouble trying to do both at the same time in same php script. I have a text file with words like this, Richmond,Virginia Seattle,Washington Los Angeles,California Dallas,Texas Jacksonville,Florida I wrote a code to sort them in order and this will display in sort order by City. <?php $file = file("states.txt"); sort($file); for($i=0; $i<count($file); $i++) { $states = explode(",", $file[$i]); echo $states[0], $states[1],"<br />"; } ?> From this, how can I rewrite those sorted information back into the states.txt file? Thanks for your help.

• md5 hash for file without File Attributes

  - by Glennular

  Using the following code to compute MD5 hashs of files: Private _MD5Hash As String Dim md5 As New System.Security.Cryptography.MD5CryptoServiceProvider Dim md5hash() As Byte md5hash = md5.ComputeHash(Me._BinaryData) Me._MD5Hash = ByteArrayToString(md5hash) Private Function ByteArrayToString(ByVal arrInput() As Byte) As String Dim sb As New System.Text.StringBuilder(arrInput.Length * 2) For i As Integer = 0 To arrInput.Length - 1 sb.Append(arrInput(i).ToString("X2")) Next Return sb.ToString().ToLower End Function We are getting different hashes depending on the create-date and modify-date of the file. We are storing the hash and the binary file in a SQL DB. This works fine when we upload the same instance of a file. But when we save a new instance of the file from the DB (with today's date as the create/modify) on the file-system and then check the new hash versus the MD5 stored in the DB they do not match, and therefor fail a duplicate check. How can we check for a file hash excluding the file attributes? or is there a different issue here?

• IO operation taking long time for files in remote server

  - by user841311

  I have files of size 150 MB each in a remote server in a different domain in the network. I am accessing them thorugh UNC path. I want to read the file content and perform a basic string search. When I try reading the files line by line, the operation just don't finish and takes long time, more than 30 minutes. However when I copy those files to my local machine, the same code reads and performs the string search in less than 5 seconds. I don't have .NET framework installed in the server so I have to do this from my machine. I want to perform all this through C# code in .NET framework 3.5 so I don't want to explictly ftp all the files to my machine before performing this operation. Sample Code DirectoryInfo dir = new DirectoryInfo(@strFilePath); FileInfo[] fiArray = dir.getFiles("*.txt"); foreach (FileInfo fi in fiArray) { //reading file content from server takes long time but fast in local machine //perform string search } Let me know if my requirement is not clear. Thanks in advance!

• Parsing SQLIO Output to Excel Charts using Regex in PowerShell

  Today Joe Webb ( Blog | Twitter ) blogged about The Power of Regex in Powershell, and in his post he shows how to parse the SQL Server Error Log for events of interest.

• Overwrite previous output in Bash instead of appending it

  - by NES

  For a bash timer i use this code: #!/bin/bash sek=60 echo "60 Seconds Wait!" echo -n "One Moment please " while [ $sek -ge 1 ] do echo -n "$sek " sleep 1 sek=$[$sek-1] done echo echo "ready!" That gives me something like that One Moment please: 60 59 58 57 56 55 ... Is there a possibility to replace the last value of second by the most recent so that the output doesn't generate a large trail but the seconds countdown like a real time at one position? (Hope you understand what i mean :))

• No output devices in sound settings - therefore, no sound

  - by Kev Quirk

  I've just performed a fresh install of Ubuntu 13.10, and I've noticed that sound isn't working. When I go to sound settings, I can see that there is absolutely no sound devices detected. However, I do have my speakers installed and turned on, plus my machine has an internal speaker as well. I've seen other posts where people mention that they have "Dummy device" listed, this isn't the problem here, the output device section is completely blank. Any help is appreciated. Thanks, Kev

• I can't capture the output screen of a game tutorial

  - by user12543

  Hello, I'm trying to do a screen capture with gtk-recordmydesktop and other capture tools but for some reason, it will not capture an output screen while its running. It captures one screen but doesn't show the rest. I can capture my screen running if I use my flip camcorder but recordmydesktop will not work. Is there a way to capture live video playing on the desktop without using an outside camera? Brian

• Using SQL Server's Output Clause

  When you are inserting, updating, or deleting records from a table, SQL Server keeps track of the records that are changed in two different pseudo tables: INSERTED, and DELETED. These tables are normally used in DML triggers. If you use the OUTPUT clause on an INSERT, UPDATE, DELETE or MERGE statement you can expose the records that go to these pseudo tables to your application and/or T-SQL code.

• Options for PCI-DSS 11.5 - Deploy file integrity monitoring software

  - by dialt0ne

  I'm looking for options to be compliant with PCI-DSS section 11.5 for some servers I manage at the datacenter.

• Windows 7 file sharing password protecting or making stuff available to just me

  - by Carbonara

  Even with the new Homegroup feature I'm still finding the way Windows deals with folder sharing utterly baffling. Here's what I want to do. I have two computers, a PC Desktop and a laptop. I also live in a shared flat with other computer users. I have set up a Homegroup and a Workgroup on the desktop and joined them on the laptop and in the home group I have shared video, music and pictures. This is so that anyone on the network can view pictures and listen to music etc. But I want my Documents folder from my desktop to only be available to me on my laptop and not to anyone else that may be on the network. The Homegroup only allows (from what I can gather from the baffling array of options) sharing with everyone or no one. Is it possible to only allow the laptop to access the documents folder on the desktop? The user name and password are the same on both computers.

• reset file permissions?

  - by acidzombie24

  In my /var/www folder i have permission 2750 with the owner being root (unless i change it by hand) and the group being www-data. I mv a folder into /var/www and i'd like to reset the permissions so everything is 2750 and for the group to be www-data, is it possible to do it in one command? or do i need to do multiple cmds? (its two commands, 3 if i want the same owner but it be nice to do it with one for this folder)

• How come the ls command prints in multiple columns on tty but only one column everywhere else?

  - by David Lou

  Even after using Unix-like OSes for a couple years, this behaviour still baffles me. When I use the ls command in a directory that has lots of files, the output is usually nicely formatted into multiple columns. Here's an example: $ ls a.txt C.txt f.txt H.txt k.txt M.txt p.txt R.txt u.txt W.txt z.txt A.txt d.txt F.txt i.txt K.txt n.txt P.txt s.txt U.txt x.txt Z.txt b.txt D.txt g.txt I.txt l.txt N.txt q.txt S.txt v.txt X.txt B.txt e.txt G.txt j.txt L.txt o.txt Q.txt t.txt V.txt y.txt c.txt E.txt h.txt J.txt m.txt O.txt r.txt T.txt w.txt Y.txt However, if I try to redirect the output to a file, or pipe it to another command, only a single column appears in the output. Using the same example directory as above, here's what I get when I pipe ls to wc: $ ls | wc 52 52 312 In other words, wc thinks there are 52 lines, even though the output to the terminal has only 5. I haven't observed this behaviour in any other command. Would you like to explain this to me?
