• Cloning a Windows server with VMWare ESXi without domain membership conflicts

  - by Brad

  We are using VMWare ESXi 3.5, and have found it quite useful for cloning a live server to then use the virtualized version to test/practice software upgrades. The trouble is, when the virtualized version fires up, it registers itself on our domain (Active Directory), causing the original server to no longer be accessible via Windows shares. The fix is to remove the virtualized version from the domain, configuring it to use a workgroup instead, deleting the Computer account in AD, and then removing the real server from the domain and re-adding it. Is there a better procedure? Note, we cannot simply disconnect the virtual network from the virtualized server, as it needs to be connected to the network to actually be removed from the domain.

• Active Directory Profile Slows down machine

  - by boburob

  I have a strange issue with an Active Directory profile. When the user logs onto a machine with his profile, the whole machine becomes incredibly slow and unresponsive, with programs hanging and taking an age to load everything. If I log into the same machine with any other profile nothing happens. I took a look at his original profile, any start up programs, login scripts, etc and could not see what could be causing this. The machine is not running out of memory or CPU. Nothing strange is appearing in the event log and I can see nothing running under his profile which may cause this. So I created the user a new profile to test this on and exactly the same thing happens on the first login. The only thing which would of been carried across is the security groups the user is assigned to, yet I have other users with the same groups who do not experience these issues so I am now at a complete loss on where to go next!

• Odd IIS v6 .html file caching behavior: Ideas?

  - by samsmith

  Our loadbalancer looks for "loadbalancer.html" So today, I deleted the file, but in a browser I could still fetch it. My eyes crossed, I made sure, 3 ways, that the file was removed from the iis web site home dir. But fetching it gave a nice 200 http response, and the file. In desperation, I created a new loadbalancer.html, and put some test text in it, and then this new content was retrieved, and then I deleted this file, and THEN it finally gave the 404 as desired. How can I better understand/control this ? Thanks!

• Is an eee-pc with an Atom N550 dual core OK for Rails 3 development?

  - by dan

  I'm buying an Asus eee-pc 1015PEM and hope to do test-driven Rails 3 development on it. Is the CPU fast enough or too painfully slow for this? I plan on installing Ubuntu. I currently develop on a 11 inch Macbook Air 2010 model. It works fine as a Rails development machine. But for some reason I'm drawn to developing on a cheap little netbook. I don't use any IDE's, and my development workflow is mostly switching between Vim, Gnu Screen, and bash.

• Can't install Ubuntu 12 into VirtualBox (USB not recognized, ISO would not boot)

  - by wvxvw

  I'm trying out VirtualBox 4.18 and wanted to install Ubuntu 12 as a test. After installing VirtualBox (on Debian squeeze/sid), creating a virtual machine for Ubuntu and pointing it in Settings Storage IDE Controllers to the ISO with the proper version of Ubuntu, checked the "Live CD" option. Tried to define the IDE as master / slave, primary / secondary - all to no effect, and trying to boot this system, I'm getting to the screen which says: FATAL: could not read from the boot medium! System halted I've copied the same ISO to the USB stick, and I can boot from the USB (outside VirtualBox). I've looked at couple of tutorials / walk-through, there's nothing I can see that I would've done wrong. So, how would I configure it to boot from the desired ISO? Below is the snapshot with the current settings (sorry, I don't know how to get them as text).

• 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?

• VLC RTP Streaming in FC12

  - by Matt D

  I'm trying to get VLC to work streaming RTP audio/video over my office network. The goal is multicast a/v streaming. In all test cases, we are streaming from VLC to VLC. I am able to stream from Windows to Windows, and from Fedora to Windows, but not from Windows to Fedora. Additionally, I am unable to receive a LOCAL stream from one instance of VLC to another, within Fedora. I don't see any reason why this would be. The buffer indicator (where the elapsed/total time is normally displayed) never shows any connectivity, so it would appear to be a network problem, but since I am able to stream from Fedora to Windows (same IP, same port) I thought it would be something else. Does anyone know of a solution to this issue?

• Web Development - How to access custom host, defined in my hosts file, from another device in the same network

  - by Neara

  Ok, I hope i'll be able to explain the issue im experiencing. I'm working on a project, that has 2 parts: one takes all requests from usual localhost, the other handles requests from myhost.local. While trying to access both addresses from my computer, it works ok. But now i need to test myhost.local on mobile devices, connected to the same network. Usually i would just run server from my computer ip in the network: python manage.py runserver 10.0.0.8:8000 And then from any device, going to 10.0.0.8:8000 would show the project im working on. However, now accessing that ip address routes me straight to localhost. So, my question is how to access myhost.local from another device in same network? I don't want to change router settings, if that can be avoided, cos sometimes i work from places where i can't access router admin. Is there any network settings on my computer, that i can change to fix the routing to myhost.local w.o losing access to localhost as well?

• Accessing WindowsXP shared printer from macbook?

  - by mobibob

  My new printer is setup on WindowsXP, it works and it is configured as a shared printer. I then setup a printer from Mac OSX 10.6.3 using the approved driver from the setup CD. I browsed for the printer via the network. When I send a test page, it queues, but never prints. Its as if the driver thinks the printer is local to the mac and just never finishes printing. THe configuration shows as: smb://dragoneye/CanonMP2 Where dragoneye is the name of the Windows XP server and the CanonMP2 is the little multi-purpose printer. My other Windows' CPU can setup and print. Is this a known problem or am I missing a setting??

• What's wrong with circular references?

  - by dash-tom-bang

  I was involved in a programming discussion today where I made some statements that basically assumed axiomatically that circular references (between modules, classes, whatever) are generally bad. Once I got through with my pitch, my coworker asked, "what's wrong with circular references?" I've got strong feelings on this, but it's hard for me to verbalize concisely and concretely. Any explanation that I may come up with tends to rely on other items that I too consider axioms ("can't use in isolation, so can't test", "unknown/undefined behavior as state mutates in the participating objects", etc.), but I'd love to hear a concise reason for why circular references are bad that don't take the kinds of leaps of faith that my own brain does, having spent many hours over the years untangling them to understand, fix, and extend various bits of code. Edit: I am not asking about homogenous circular references, like those in a doubly-linked list or pointer-to-parent. This question is really asking about "larger scope" circular references, like libA calling libB which calls back to libA. Substitute 'module' for 'lib' if you like. Thanks for all of the answers so far!

• Flash Media Server slow over SSL

  - by Antilogic

  We are using FMS to host a VoD site. We host FMS internally (we do not use a CDN). We recently installed an SSL certificate to alleviate connection issues for clients (they're networks either block or don't support RTMP), however we're noticing that when streaming in RTMPS connections are drastically slower (on the order of Mbps). I know SSL causes some amount of over head but both client and server show almost no signs of exertion. Speedtest.net and a locally hosted speed test confirm that bandwidth is not an issue. I'm really not a network guru, so I'm at a loss as to where to check next. Do any of you have an idea why streaming media would run so slow over SSL?

• pymatplotlib without xserver

  Is it possible to use networkx or pymatplotlib without an xserver running? I keep getting the following error with their first example (of networkx): Traceback (most recent call last): File "test.py", line 17, in <module> nx.draw(G,pos,node_color='#A0CBE2',edge_color=colors,width=4,edge_cmap=plt.cm.Blues,with_labels=False) File "/usr/local/lib/python2.6/dist-packages/networkx-1.3-py2.6.egg/networkx/drawing/nx_pylab.py", line 124, in draw cf=pylab.gcf() File "/usr/lib/pymodules/python2.6/matplotlib/pyplot.py", line 276, in gcf return figure() File "/usr/lib/pymodules/python2.6/matplotlib/pyplot.py", line 254, in figure **kwargs) File "/usr/lib/pymodules/python2.6/matplotlib/backends/backend_tkagg.py", line 90, in new_figure_manager window = Tk.Tk() File "/usr/lib/python2.6/lib-tk/Tkinter.py", line 1646, in __init__ self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use) _tkinter.TclError: couldn't connect to display ""

• CHROOT for shell script testing

  - by Josh

  I am looking at setting up a shell script in order to properly document and automate the process I am using to setup a few servers we have. In order to test the shell script through its different stages I was thinking a CHROOT would be ideal, since I can wipe out the "virtual root" and create it on the fly. I have never used CHROOT before, however. I was just curious what are the exact steps I would need to follow to implement this process of creating a chroot (with the basic core functions that would be needed to install apache/php/etc.)? and then destroying it?

• Testing a Virtualisation of a Debian Server (vmWare vSphere probably)

  - by xyza

  I'm soon getting access to a powerful root-server (quad-core, 16gb ram, 1gbit connection) where gameservers (like minecraft,counterstrike etc.) for different customers should be setup. My plan is to use programs such as vmWare vSphere to create some virtual machines for each customer. Inside such a virtual machine I'll setup the gameserver and maybe some kind of ftp server when its needed. Now that I'm kinda new to virtualisation of servers I want to test this local on my Desktop Computer. Is it possible to create a virtual machine of debian using vmWare Player on my Windows desktop computer and then install vmware vSphere in this VM to create multiple VM's inside that VM ? Or do I really need to install Debian on my desktop computer. (I want to use the time during installations etc. to work a bit at my windows installation) Some tips on virtualising debian servers are also appreciated :)

• Changing size of window when testing Adobe AIR mobile applications

  - by Peter

  Im making a mobile phone Android application in Flash CS 5.5. I set the width/height of the stage to 480/800 px. When I hit CTRL+ENTER to test run the application I get a window that is 480/800 px. It cannot be resized. I want to change the size of that window WITHOUT changing the stage width/height. For example if I run the APK on a mobile phone with a 1000x1000 display the flash will scale automatically to fit the 480/800 stage to the 1000x1000 screen. So it should be possible to change the window size to 1000x1000 without having to change the stage width/height. But how?

• Why is math taught "backwards"? [closed]

  - by Yorirou

  A friend of mine showed me a pretty practical Java example. It was a riddle. I got excited and quickly solved the problem. After it, he showed me the mathematical explanation of my solution (he proved why is it good), and it was completely clear for me. This seems like natural approach for me: solve problems, and generalize. This is very familiar to me, I do it all the time when I am programming: I write a function. When I have to write a similar function, I generalize the problem, grab the generic parts, and refactor them to a function, and solve the original problems as a specialization of the general function. At the university (or at least where I study), things work backwards. The professors shows just the highest possible level of the solutions ("cryptic" mathematical formulas). My problem is that this is too abstract for me. There is no connection of my previous knowledge (== reality in my sense), so even if I can understand it, I can't really learn it properly. Others are learning these formulas word-by-word, and get good grades, since they can write exactly the same to the test, but this is not an option for me. I am a curious person, I can learn interesting things, but I can't learn just text. My brain is for storing toughts, not strings. There are proofs for the theories, but they are also really hard to understand because of this, and in most of the cases they are omitted. What is the reason for this? I don't understand why is it a good idea to show the really high level of abstraction and then leave the practical connections (or some important ideas / practical motivations) out?

• The Home Stretch: NetBeans IDE 7.1 Release Candidate

  - by TinuA

  The first release candidate build of NetBeans IDE 7.1 is live and available for download, which means the big release (GA) is expected any day soon.NetBeans IDE 7.1 delivers support for JavaFX 2.0, enabling the full compile, debug and profile development cycle for JavaFX 2.0 applications and keeping developers in sync with the latest from the Java platform. Beyond JavaFX support, 7.1 also provides significant Swing GUI Builder enhancements, CSS3 support, and visual debugging tools for JavaFX and Swing user interfaces. And Git--a much anticipated featured--has been integrated into the IDE."The entire NetBeans team is tremendously excited about this release, which provides developers with more state-of-the-art tools for building front-end clients," says NetBeans Engineering Director John Jullion-Ceccarelli. "Whether you are doing JavaFX, HTML5, Swing, or JSF, NetBeans 7.1 will let you quickly and easily develop great-looking and full-featured clients for your Java or PHP-based applications."But there's one more task to check off before the general availability: The NetBeans team has launched a Community Acceptance Survey to get user feedback about the release candidate. Download the RC build, test it and take the survey to let the team know if NetBeans IDE 7.1 is ready for its debut!

• Backups of Exchange 2007 SP3 using VSS are abnormally large

  - by Stew

  I have recently implemented Veeam backup and recovery 6.0, and have noted when backing up my exchange server via incremental updates, it is transferring way more data than expected. Backup is incremental, and setup to use VSS. VSS is stable and healthy, according to vssadmin. Exchange 2007 SP3 running on Windows Server 2008 R2, just last weekend I installed the latest Rollup for Exchange. I thought the nightly incrementals were large, but perhaps my users really are sending that much mail so I tested taking one incremental backup, waiting 10 minutes and taking a second. The second incremental backup transfered 5.8GB of data. We as an organization are absolutely NOT putting 5.8GB of data on the mail server every 10 minutes. Are there any other veeam users who have seen something similar? Is my test faulted? Are there other considerations for VSS?

• How do I reset the $PATH variable on Mac OS X?

  - by Neil

  I've messed up my path variable, and now some apps that I run raise errors saying Command Not Found (error 127) for commands like 'date' and 'sleep'. These commands work fine when executed directly in the shell. I'm guessing this has something to do with a malformed $PATH variable, and need to know how to reset it. I've deleted the files ~/.bashrc , ~/.bash_profile, /etc/bash.bashrc, and ~/.bashrc and ~/.profile. What other files could hold my $PATH? Is there some simpler way to reset the Path than dig into the myriad files which could hold my path? Note, this path problem is only with my user. I made a test user on my system, and the path was fine, back to normal.

• How can my team avoid frequent errors after refactoring?

  - by SDD64

  to give you a little background: I work for a company with roughly twelve Ruby on Rails developers (+/- interns). Remote work is common. Our product is made out of two parts: a rather fat core, and thin up to big customer projects built upon it. Customer projects usually expand the core. Overwriting of key features does not happen. I might add that the core has some rather bad parts that are in urgent need of refactorings. There are specs, but mostly for the customer projects. The worst part of the core are untested (as it should be...). The developers are split into two teams, working with one or two PO for each sprint. Usually, one customer project is strictly associated with one of the teams and POs. Now our problem: Rather frequently, we break each others stuff. Some one from Team A expands or refactors the core feature Y, causing unexpected errors for one of Team B's customer projects. Mostly, the changes are not announced over the teams, so the bugs hit almost always unexpected. Team B, including the PO, thought about feature Y to be stable and did not test it before releasing, unaware of the changes. How to get rid of those problems? What kind of 'announcement technique' can you recommend me?

• Is HDCP working for ATI/AMD cards on windows 8?

  - by Joel Barsotti

  I have an AMD 6950 and am running windows 8 RTM. I've tried the Catalyst 12.8 drivers and the 12.9 beta drivers. With either drive HDCP seems to be non operational. I've got two dell monitors, one a u2410 and the other a 2408wfp. Both were previously identified as supporting HDCP in windows 7 with the same hardware. I've tested the monitors individual on both DVI and display port, and neither one works. I'm using cyberlinks BD-Advisor to test. My end goal is getting the DirecTv2PC app working again, which is by cyberlink for DirecTV, and requires HDCP. Currently it shuts off when you start playing a recording.
