• Server 2008 Active directory file sharing Restriction

  - by Usman

  My network scenario is: Two location connected each other through Wireless towers. 1st network ip address are 10.10.10.1 to 10.10.10.150 2nd network ip address are 10.10.10.200 to 10.10.10.254 Both location using their own ACTIVE DIRECTORY (MS SERVER 2008) and share their data with each other network through file sharing. My Problem is that every single client can explore the whole network. by simply typing \computername. i want to implement some restriction on network regarding file sharing. i want to restrict 1st Network Clients to open 2nd network Computer or server. Is there have any Group Policy or Folder permission scenario that i implement on my both network..

• Octrees and Vertex Buffer Objects

  - by sharethis

  As many others I want to code a game with a voxel based terrain. The data is represented by voxels which are rendered using triangles. I head of two different approaches and want to combine them. First, I could once divide the space in chunks of a fixed size like many games do. What I could do now is to generate a polygon shape for each chunk and store that in a vertex buffer object (vbo). Each time a voxel changes, the polygon and vbo of its chunk is recreated. Additionally it is easy to dynamically load and reload parts of the terrain. Another approach would be to use octrees and divide the space in eight cubes which are divided again and again. So I could efficiently render the terrain because I don't have to go deeper in a solid cube and can draw that as a single one (with a repeated texture). What I like to use for my game is an octree datastructure. But I can't imagine how to use vbos with that. How is that done, or is this impossible?

• How to copy text out of a PDF without losing formatting?

  - by Colen

  When I copy text out of a PDF file and into a text editor, it ends up mangled in a variety of ways. Formatting like bold and italics are lost; soft line breaks within a paragraph of text are converted to hard line breaks; dashes to break a word over two lines are preserved even when they shouldn't be; and single and double quotes are replaced with ? signs. Ideally, I'd like to be able to copy text from a PDF and have formatting converted to HTML codes, "smart quotes" converted to " and ', and line breaks done properly. Is there any way to do this?

• Can't change folder background

  - by newcomer

  I tried to change via dragging from the Backgrounds and Emblems window, but the icon just goes back to that window rather than changing the folder background.However, I can change the task bar by this drag-n-drop. Probably it is something about changing ownership permission? if so how to change that? In /home/mashruf/.gconf/apps/nautilus/preferences/%gconf.xml file it says:, Should I change this file? how? <?xml version="1.0"?> <gconf> <entry name="click_policy" mtime="1297597800" type="string"> <stringvalue>single</stringvalue> </entry> <entry name="default_folder_viewer" mtime="1297597336" type="string"> <stringvalue>list_view</stringvalue> </entry> <entry name="media_autorun_x_content_open_folder" mtime="1297534321" type="list" ltype="string"> </entry> <entry name="media_autorun_x_content_ignore" mtime="1297534321" type="list" ltype="string"> </entry> <entry name="media_autorun_x_content_start_app" mtime="1297534321" type="list" ltype="string"> <li type="string"> <stringvalue>x-content/software</stringvalue> </li> </entry> <entry name="start_with_location_bar" mtime="1297300028" type="bool" value="true"/> <entry name="side_pane_view" mtime="1297269334" type="string"> <stringvalue>NautilusTreeSidebar</stringvalue> </entry> <entry name="navigation_window_saved_maximized" mtime="1297600306" type="bool" value="false"/> <entry name="navigation_window_saved_geometry" mtime="1297600306" type="string"> <stringvalue>964x608+59+2</stringvalue> </entry> <entry name="sidebar_width" mtime="1297390418" type="int" value="192"/> </gconf>

• Ubuntu 11.10 loads from live usb fine, but boots to black screen from harddrive. Why?

  - by Estel

  A few days ago I had a hard drive failure, which was running Windows XP (32-bit) just fine. The second hard drive in my computer held a few unimportant files, so I formatted it in the Ubuntu setup and installed 11.10 without a hitch. I had been using it for about a week, but decided to install Windows 7 (64-bit) in order to utilize Networking with my home server (running Windows Server 2000). My system is 64-bit based, and thus I had no problems installing other than a basic RAM error that required me to remove my RAM down to a single stick. I played with the settings in Windows 7 for around an hour before I shut down. After reinstalling the RAM, Windows 7 would not boot. In this, I then assumed that something about my system was rejecting Win7 and I reinstalled Ubuntu. However, now Ubuntu (11.10) boots into black screen, and I've already attempted activating the grub menu with the shift key, and following steps listed here: https://wiki.ubuntu.com/X/Troubleshooting/BlankScreen but nothing seems to work. I've reinstalled twice now, with the same result each time. Now, the very odd part about this whole scenario is that the USB I installed from has no problems booting as a live USB. This puzzles me greatly, because the hard drive boots straight to black screen and the live USB loads normally. At this point, my only theory is that the boot sector of the hard disk was somehow corrupted with Win7, and that Ubuntu was unable to completely write through. I used Darik's Boot n Nuke to wipe the drive, but was met with an error, this also puzzles me because the hard disk has no promblems reading or writing. Any suggestions/comments are appreciated. If you have a theory, I will be more than happy to oblige. Additional information: Intel Core2 Duo e6400 2.13GHz nVidia GeForce 7-series (7900 GS) 4 GB DDR2 333MHz (2x 2GB) Dell XPS 410 BIOS Revision 2.5.3

• What are the Windows G: through Z: drives used for?

  - by Tom Wijsman

  In Windows you have a C: drive. The first things labeled beyond that seems to be extra stuff. So my DVD drive is D: and if you put in a USB stick it becomes F:. And then some people also have A: and B:. But then, what and where are G: through Z: drives for? Is it possible to connect so many things to a computer to make them all in use? Or more than them? Would it give a BSOD? Or would this slow down the system somehow? Or what would happen? What if I want to connect even more drives to the computer? Because with the hard drive limits it's more efficient to buy more drives than to buy a single drive with a lot of capacity. Is it possible to create drive letters like 0: through Z: or AA: through ZZ:?

• How do I properly center Nifty GUI elements on screen?

  - by Jason Crosby

  I am new to JME3 game engine but I know Android XML GUI layouts pretty good. I have a simple layout here and I cant figure out what is wrong. Here is my XML code: <?xml version="1.0" encoding="UTF-8"?> <nifty xmlns="http://nifty-gui.sourceforge.net/nifty-1.3.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://nifty-gui.sourceforge.net/nifty-1.3.xsd http://nifty-gui.sourceforge.net/nifty-1.3.xsd"> <useControls filename="nifty-default-controls.xml" /> <useStyles filename="nifty-default-styles.xml" /> <screen id="start" controller="com.jasoncrosby.game.farkle.gui.MenuScreenGui"> <layer id="layer" backgroundColor="#66CD00" childLayout="center"> <panel id="panel" align="center" valign="center" childLayout="center" visibleToMouse="true"> <image filename="Textures/wood_floor.png" height="95%" width="95%"/> <panel id="panel" align="center" valign="center" childLayout="center" visibleToMouse="true"> <text text="test" font="Interface/Fonts/Eraser.fnt"></text> </panel> </panel> </layer> </screen> Everything works well until I get to displaying the text. I have tried different alignments and tried moving the text into different panels but no matter what I do the text is never in the center of the screen. It's always in the upper left corner, so far I can only see the lower right part of the text. How can I center the text element in the center of the screen?

• Firefox cannot recognize certificates for well knows sites

  - by RCola

  When trying to connect to well known sites, for instance hotmail.com Firefox shows that This Connection in Untrusted. In the OptionsAdvancedCertificates it's configured to select one matching certificate automatically. Why Firefox does not trust current connection? Can it be Man-in-the-middle attack or it's something like broken certificate storage on my computer? UPDATE UPDATE2 Solved: the problem is Antivirus Web Access protection. It interferes with HTTPS connection. Similar to Man-in-the-middle? Why ESET cannot do it correctly?

• uWSGI and python virtual env

  - by user27512

  I'm trying to use uWSGI with a virtual env in order to use the Trac bug tracker on it. I've installed system-wide uwsgi via pip. Next, I've installed trac in a virtualenv $ virtualenv venv $ . venv/bin/activate $ pip install trac I've then written a simple uWSGI configuration script: [uwsgi] master = true processes = 1 socket = localhost:3032 home = /srv/http/trac/venv/ no-site = true gid = www-data uid = www-data env = TRAC_ENV=/srv/http/trac/projects/my_project module = trac.web.main:dispatch_request But when I try to launch it, it fails: $ uwsgi --http :8000 --ini /etc/uwsgi/vassals-available/my_project.ini --gid www-data --uid www-data ... Set PythonHome to /srv/http/trac/venv/ ... *** Operational MODE: single process *** ImportError: No module named trac.web.main unable to load app 0 (mountpoint='') (callable not found or import error) I think uWSGI isn't using the virtual env. When inside the virtual env, I can import trac.web.main without having an ImportError. How can I do that ? Thanks

• What poor management decisions have you had to deal with?

  - by tombull89

  As a junior technician I've had to deal with (or will have to deal with) some problems in the past and only being a junior technician I don't have the confidence or respect from management staff to speak up. For instance, we're having a entirely new system. From Windows Server 2003/XP going to Windows Server 2008 R2/Windows 7/VMWare/Digital Signage and the current amount of time dedicated to the training of the IT support department currently stands at 0. They seem to think that all IT systems are the same and are going to get a bit of shock when I can't help them. I think there;s some UK legislation saying a school/business have to put money and time aside for training, but I'm not sure. What have you had to deal with?

• Windows 7: enabling navigation of subfolders in pinned Start Menu folders

  - by AspNyc

  I'm just about to move from Windows XP to Windows 7, and I'm struggling with some of the interface changes. In XP, I was able to throw a folder intoC:\Documents and Settings\username\Start Menuand have it appear on the Start Menu, complete with the ability to navigate through subfolders. I've figured out how to pin a folder onto the Start Menu in Windows 7, which required a registry hack. However, I am unable to view the subfolders of the pinned folder without opening a new Windows Explorer window. Is there any way to replicate the old XP behavior I'm used to? I'd like to be only a single click away from these handful of application links and folders, since I use them all the time throughout the day.

• getting started as a web developer [closed]

  - by kmote

  I have over 10 years of programming experience building (Windows-based) desktop applications and utilities (VC++, C#, Python). My goal over the next year is to start transitioning to web application development. I want to teach myself the fundamental tools and technologies that would be considered essential for building professional, online, interactive, visually-stunning, data-driven web apps -- the kind described in Google's recently released "Field Guide: Building Great Web Applications". So my question is, what are the primary, most commonly-used technologies that seasoned professionals will need in their tool belt in the coming years? My plan was to start coming up to speed in Javascript, HTML5, & CSS, and then to do a deep dive into ASP.NET and Ajax, along with SQL DBs. (I was surprised to not be able to find a single book at Amazon with a broad, general scope like this, which caused me to start second-guessing this approach.) So, seasoned professionals: am I on the right track? Are there some glaring omissions in my list? Or some unnecessary inclusions? I would welcome any book suggestions along these lines as well.

• Dediced server for all network functions?

  - by Alan

  I want to set up a fictional network configuration for a school in my neighborhood. They have about 50 computers altogether, 2X20 in computer rooms for students and another 10 scattered around for various professors. They should all access the internet through a dedicated Linux router machine. What they would like is to have domain names for those three computer groups. Lab1, Lab2 and Professors. The computers in Lab2 and Lab1 should have static ip and should all be named by numbers. So there should be 1@Lab1, 2@Lab1.... etc. And the Professors network should have a DHCP, with authentication. Is it an ok solution to have all these functions on a single server? (The one which will be used as a router) Do I have to set a local DNS for domain naming? Do the host names for Lab computers have to be set on the clients, or can they be automatically assigned?

• String manipulation functions in SQL Server 2000 / 2005

  - by Vipin

  SQL Server provides a range of string manipulation functions. I was aware of most of those in back of the mind, but when I needed to use one, I had to dig it out either from SQL server help file or from google. So, I thought I will list some of the functions which performs some common operations in SQL server. Hope it will be helpful to you all. Len (' String_Expression' ) - returns the length of input String_Expression. Example - Select Len('Vipin') Output - 5 Left ( 'String_Expression', int_characters ) - returns int_characters characters from the left of the String_Expression.     Example - Select Left('Vipin',3), Right('Vipin',3) Output -  Vip,  Pin  LTrim ( 'String_Expression' ) - removes spaces from left of the input 'String_Expression'  RTrim ( 'String_Expression' ) - removes spaces from right of the input 'String_Expression' Note - To removes spaces from both ends of the string_expression use Ltrim and RTrim in conjunction Example - Select LTrim(' Vipin '), RTrim(' Vipin ') , LTrim ( RTrim(' Vipin ')) Output - 'Vipin ' , ' Vipin' , 'Vipin' (Single quote marks ' ' are not part of the SQL output, it's just been included to demonstrate the presence of space at the end of string.) Substring ( 'String_Expression' , int_start , int_length ) - this function returns the part of string_expression. Right ( 'String_Expression', int_characters ) - returns int_characters characters from the right of the String_Expression.

• Transparent JPanel, Canvas background in JFrame

  I wanna make canvas background and add some elements on top of it. For this goal I made JPanel as transparent container with setOpaque(false) and added it as first of JFrame container, then I added canvas with black background (in future I wanna set animation) to JFrame as second element. But I can't undestand why i see grey background, not a black. Any suggestions? public class Game extends JFrame { public Container container; //Game container with components public Canvas backgroundLayer; //Background layer of a game public JPanel elementsLayer; //elements panel (top of backgroundLayer), holds different elements private Dimension startGameDimension = new Dimension(800,600); //start game dimension public Game() { //init main window super("Astra LaserForces"); setSize(startGameDimension); setBackground(Color.CYAN); container=getContentPane(); container.setLayout(null); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //init jpanel elements layer elementsLayer=new JPanel(); elementsLayer.setSize(startGameDimension); elementsLayer.setBackground(Color.BLUE); elementsLayer.setOpaque(false); container.add(elementsLayer); //init canvas background layer backgroundLayer = new Canvas(); backgroundLayer.setSize(startGameDimension); backgroundLayer.setBackground(Color.BLACK); //set default black color container.add(backgroundLayer); } //start game public void start() { setVisible(true); } //create new instance of game and start it public static void main(String[] args) { new Game().start(); } }

• How to plan/manage multi-platform (mobile) products?

  - by PhD

  Say I've to develop an app that runs on iOS, Android and Windows 8 Mobile. Now all three platforms are technically in different program languages. The only 'reuse' that I can see is that of the boxes-and-lines drawings (UML :) charts and nothing else. So how do companies/programmers manage the variation of the same product across different platforms especially since the implementation languages differ? It's 'easier' in the desktop world IMO given the plethora of languages and cross-platform libraries to make your life easier. Not so in the mobile world. More so, product line management principles don't seem to be all that applicable - what is same and variant doesn't really matter - the application is the same (conceptually) and the implementation is variant. Some difficulties that come to mind: Bug Fixing: Applications maybe designed in a similar manner but the bug identification and fixing would be radically different. A bug on iOS may/may-not be existent for that on Android. Or a bug fix approach on one platform may not be the same on another (unless it's a semantic bug like a!=b instead of a==b which would require the same 'approach' to fixing in essence Enhancements: Making a change on one platform would be radically different than on another Code-Design Divergence: They way the code is written/organized, the class structures etc., could be very different given the different implementation environments - leading to further reuse of the (above) UML models. There are of course many others - just keeping the development in sync and making sure all applications are up to the same version with the same set of features etc. Seems the effort is 3x that of a single application. So how exactly does one manage this nightmarish situation? Some thoughts: Split application to client/server to minimize the effect to client side only (not always doable) Use frameworks like Unity-3D that could take care of the cross-platform problem (mostly applicable to games and probably not to other applications etc.) Any other ways of managing a platform line? What are some proven approaches to managing/taming the effects?

• Can there be multiple monitors with these video cards and setup

  - by z_Zelman

  I have a Acer Aspire TimelineX 4830TG-6808 laptop running windows 7 Ultimate with one VGA port and one HDMI port. It has one Intel HD Graphics family card and one NVIDIA GeForce GT 540M. Right now I have one monitor running via the VGA port, and also the basic laptop monitor. When I look at the monitor setup, I see one unused video card available. Can I have another monitor via the HDMI port? If I cannot run three monitors, is there some way I could make a large "single" desktop that extends over two monitors? For the sake of celerity, maybe something like having a virtual machine window that extends over two monitors. Could this maybe come from third party software?

• Setting up Dependencies for Nagios

  - by hfranco

  I'm trying to setup dependencies for a router and several servers. What I want to do is setup the router as the Master Host so if the router fails all other services on the servers won't alert. Unfortunately this is easier said than done. Is there an easy way to setup service dependencies for all services on a server for a Master Host (or my router)? Nagios has some documentation but it will be extremely time consuming to add a single service dependency definition for every service. http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#servicedependency

• internet speed and routers are controlled by whom

  - by Ozgun Sunal

  i need to learn two things. each is related to other a bit. The first one is, while our LAN speed is usually 100 Mbps or at gigabit levels(very big compared to WAN speeds), WAN speed for instance DSL connections are far less than this. However, we are able to download huge files at those Mb speeds. Isn't this weird? [my real concern is why WAN speed is lower than LAN speeds] Who controls those routers around the large Internet? (while we, as web clients are connected to Internet, packets travel through those routers to the destination network/s).But, are those routers all inside the ISP network and if not, who controls those large numbers of routers?

• Get the interface and ip address used to connect to a specific host (ip)

  - by umop

  I'm sure this has been asked and answered before, but I wasn't able to find it, so hopefully this will at least link someone to the right place. I want to find out my local interface and ip address used to reach a certain host. For instance, if I had 3 adapters connected to my box and they all three went to different networks, I'd like to know which of the three (specifically, its ip address) is used to reach my.local.intranet (in this case, it would be a vpn tunnel interface). I suspect this is a job for ifconfig or traceroute, but I haven't been able to find the correct switches. I'm running OSX 10.7 (Darwin) Thanks!

• windows phone 8 on remote hyper-v server

  - by Davy

  I downloaded the new SDK and installed on my Windows 8 instance on my dedicated Hyper-V Server. When I start the emulator I receive an error. And after some searching and reading I realised that hyper-v is not supported. Is there any possibilities that I can run my Windows phone 8 emulator on a remote Hyper-V 2012 server? What I can see, it only uses the built-in hyper-v server in windows 8 as default. Can i change it somewhere? /Davy
