  • Overloading new, delete in C++

    - by user265260
    i came across this line is stroustrup An operator function must either be a member or take at least one argument of a user-defined type (functions redefining the new and delete operators need not). Dont operator new and operator delete take an user defined type as one of their arguments? what does it mean, am i missing something here

  • Remote X-windows between new RHEL5 and old Solaris 8

    - by joshxdr
    I have a very small lab network with three boxes: a modern x86-based RHEL3 box, an x86-based RHEL5 box, and a 1998-vintage SPARC Ultra5 with Solaris 8. I can use ssh -X to run a program on the RHEL5 box and view the windows on the RHEL3 box. I believe this uses xauth and magic cookies?? I have followed the X-Windows HOWTO to set up xauth on the Solaris box, but so far no dice. I would like to be able to use the X-windows server on the RHEL3 box with a client program on the Solaris box (program running on Solaris host, windows appearing at Linux host). Is there a trick to this, or have I made a mistake following the instructions for setting up xauth and magic cookie?

  • Adding a new USB port inside a Macbook Pro

    - by MikeC8
    I have a USB Dongle that I'd like to put inside my Macbook Pro. I have already found a spot that will fit the dongle. The next question is splicing one of the USB ports and connecting it to the dongle. Here's a photograph of the inside of my Macbook Pro, showing the USB ports and a little gray plastic divider with four holes in it above each port. http://min.us/mvoQEem My question: Does anyone know what is inside these holes? Presumably each one is a pin for the USB port, right? Can I just stick a wire in there, giving me 4 pins, plus the fifth attached to the metal outside the port? More generally, any one have any ideas for what might be the easiest way to get a USB port inside my MBP? :) Thanks!

  • Netgear CG3000D new Modem/Router - Random High Ping

    - by justin.chmura
    Cox just recently came out and looked at my internet and decided that the modem I had was causing high latency issue. The speed was fine but the ping would spike to around 100 and over when gaming or putting a load more than browsing on the line. After they replaced it, it seems like I get better latency, but when it spikes, I get upwards of over 300 ping with like 500 jitter. I figured I would hit the serverfault universe before sending another email to Cox. I opted not to do the Cox setup as it was an extra $20 which I thought would have just setup the wireless (which I can handle). Is it a setting or something that I missed that needs to be setup? The firmware for the CG3000D is awful and not fun to use. I did change some hidden settings on the RgServices.asp page (I'll attach a screenshot). I've also heard that the Router/Modem combos are awful and that I should go back and just ask for a modem stand-alone. Any input is helpful. All screenshots: http://imgur.com/a/JX6qu#0

  • How to get new screws for HP Dv7 laptop

    - by blaine
    The other day I have noticed that there are 3 screws missing from the bottom of my 3 month old HP Pavilion dv7t-7000 laptop. This is causing me various problems such as an unstable screen, and who knows what else soon. My laptop is still under the basic warranty, however, I live outside the USA where I purchased it. What is the best way to get replacement screws for my laptop besides looking around the house and trying to find one that fits? Let me know if you need pictures

  • Why doesn't NFS recognize a new UID?

    - by user76177
    I have two servers running RHEL6. I have root access to both. The main server, which I will refer to as server, is a database server. The application server, which I will refer to as client, mounts a directory from server via NFS. There is a user, appuser, on both client and server. However, appuser's UID on client is 502. appuser's UID on server is 506. Both users need read and write capability on the NFS share. To facilitate this, I made the share owned by appuser on server. Running id appuser on each yields: uid=506(appuser). Of course, client does not recognize that ownership, since appuser has a different id on client. So I did the following: Changed UID of user in /etc/passwd on client to be 506. Changed ownership of appuser's $HOME on client to be appuser again so that I could log in. Now, when I go to look at the NFS share from the client side, I see that it is owned by 502. 502 is the OLD id for appuser on client. I can't change ownership of the NFS share from client, since that is a volume that physically resides on server. I need to make sure that the NFS share shows ownership of appuser from both server and client. What step have I missed since changing the appuser id on client? NOTE: I have not rebooted client (or anything else.)

  • Installed Bunch of New Fonts on Windows 7 - Now None Show Up and System Lags

    - by Josh Stodola
    So I went to install about 5,000 fonts on my Windows 7 64-bit machine. It was slow to install them, and I had to leave. I came back and my PC was shut down, and I had to go through the Windows recovery BS when I powered it on. Now my computer runs EXTREMELY slow and any program that has a font menu locks up my whole machine (nothing in Microsoft Office works). When I go to "Fonts" in the control panel, it says 0 items. I went through all of the font settings trying to get them to appear. Nothing helps. I tried to bring up the Character Map and that froze up my machine too. How can I fix this? If I do not get this issue resolved soon, I am wiping this drive and going back to XP (and probably never purchasing another version of Windows again). I never had any issues with XP and have had nothing but performance problems when switching to Windows 7. My quad-core intel extreme with 8GB of RAM should never flinch with the kind of work that I do, and something simple like playing a song off an external HD takes up to five seconds on Windows 7. Unbelievable that I had to pay for this crap!

  • Transferring NS records to a new server

    - by lanemiller
    I feel like that was NOT worded well, but here is my current predicament. I recently had a GoDaddy dedicated server, and decided after their customer support failed to do anything but disappoint, to switch to Rackspace. We have 2 ns records that point to our godaddy server, and we have a few sites left on the server, that rely on it for their DNS zones, and the owners of the domains fail to respond to us. So, the question is, if I need to transfer the sites off of the OLD godaddy NS, can I point the A records from my ns1.domain.com and ns2.domain.com to match up with IP addresses of the Rackspace nameservers? OR, do I cname my NS records to match the rackspace ones? I DO know that this isn't advised, either method, but I need to get these sites moved before Godaddy tries charging another $2k for the server.

  • 500 Internal Server Error after moving Joomla installation to new environment

    - by rad
    (This is the first time I moved the website so please don't be hard on me.) After moving the website, the homepage shows up properly but other pages do not. I get 500 Internal Server Error on all other pages. Before moving, the Search Engine Friendly URLs and Use URL rewriting were enabled in the Joomla Dashboard. Is this the reason the other pages are not showing up? If so, how do I fix this? I think the homepage shows up because the url myWebsite.com redirects to myWebsite.com/index.php automatically. Note that I have transferred all of the Joomla the files through Filezilla and imported the MySQL database properly and also edited the configuration.php as set the proper settings for the database.

  • Create new vsftpd user and lock to (specify) home / login directory

    - by Geoff Jackson
    I need to periodically give temporary and limited access to various directories on a CentOS linux server that has vsftp installed. I've created a user using useradd [user_name] and given them a password using passwd [password]. I've created a directory in /var/ftp and then I bind this to the directory that I wish to limit access to. What else do I need to specifically do to ensure that when this user logs into FTP, they only have access to this directory please?

  • New Windows 7 Install Crashing

    - by bobber205
    One big reboot crash and one smaller crash already, 15 minutes in. Did a basic install of Windows 7, installed Chrome and Firefox. I had just finished loading up my gmail account in Chrome/Firefox to show the speed difference and we'd thought it would be hilarious to see how slow IE8 was. :P Just about as IE8 was done opening, the computer's screen goes black. After a restart and a couple minutes, Explorer crashes as well. What is going on? This install is only 15-20 minutes old. :P

    We just installed a Windows 2008 Enterprise server and I'm having a problem joining the domain. We're running Ubuntu Server, OpenLdap with Samba shares.

  • Upgrading Windows 7 on a new Netbook - Problems

    - by Swaffle
    I know this seems like a repeat of a question but i didn't get a clear answer from reading the other questions so im going to ask mine and hope i hear back good news. I bought an Acer Aspire one netbook with windows 7 starter. I have a DVD of Windows 7 Professional(x86) from MSNDAA through my college but when i tried to install it, i was given an error saying that i could only upgrade through the "Windows Anytime Upgrade" Though, it only gives me the options of paying for an upgrade, which im not willing to do, or putting in an upgrade key. I have a legitimate product key for windows 7 but it does not work for upgrading and the DVD does not allow for it. Am i doing something wrong? is there another option? can i convert my product key to an upgrade key ? Im up for any option, windows 7 starter is pretty limited in its features...

  • USB port causing device problems after new motherboard upgrade

    - by enbuyukfener
    I'm looking into a PC with an issue with one of the front USB ports (perhaps both). It was working before a motherboard upgrade but since then, a USB drive was inserted, overheated and does not appear to be working. Then a phone (with USB charging) was plugged in, and the phone OS suspended. Removing and re-inserting the battery led to the phone (and hence battery) working, however the battery no longer charges (including with a wall charger). It seems too much to be a coincidence and am wondering what the issue may be? Ideas so far are short circuiting, or over-current to the USB ports. Note: Did not occur to me, so details are not 100% accurate or complete. Feel free to ask for missing info that I may have forgotten though.

  • umask is being ignored on Gentoo while creating new files

    - by drcelus
    I have a server running Gentoo and hosting a drupal installation. Whenever a Drupal update is executed, the directory permissions of the updated module turn from 755 to 744 preventing the application from accessing the files. The umask is defined as 022 under /etc/profile and the Apache server is running under user and group nobody. I believe this has nothing to do with the drupal installation since if I create a directory as root, the same happens, it is created with 744 permissions, since the umask is 022 shouldn't it be created as 755 ? Why is the umask being ignored and how do I tell the server to create the directories with permission 755 ?

  • Loading from pickled data causes database error with new saves

    - by hibbie
    In order to save time moving data I pickled some models and dumped them to file. I then reloaded them into another database using the same exact model. The save worked fine and the objects kept their old id which is what I wanted. However, when saving new objects I run into nextval errors. Not being very adept with postgres, I'm not sure how to fix this so I can keep old records with their existing ID while being able to continue adding new data. Thanks, Thomas

  • How to install a new PHP extension on IIS 7.5

    - by Razor
    I have installed PHP 5.2.13 through Web Platform Installer on IIS 7.5/windows 2008 R2 Now I'm trying to install additional PHP extensions, such as mcrypt, so I downloaded the compiled .zip file from the php windows binaries site. I put the relevant dlls in the extensions folder, and added the lines in the php.ini: [PHP_MCRYPT] extension=php_mcrypt.dll After restarting IIS, no application was working. This was with VC6 compiled/non thread-safe compiled version of PHP 5.2.13 .zip package. I also tried with the thread-safe version, which prevented IIS to restart and forced me to reboot the server. What am I doing wrong here?
