  • Why are hard drives moving to 4096 byte sectors, vs. 512 byte sectors?

    - by Chris W. Rea
    I've noticed that some Western Digital hard drives are now sporting 4K sectors, that is, the sectors are larger: 4096 bytes vs. the long-standing standard of 512 bytes. So: What's the big deal with 4K sectors? Is it marketing hype, or a real advantage? Why should somebody building a new PC care, or not, about 4K sectors? Why is this transition taking place now? Why didn't it happen sooner? Are there things to look out for when buying a 4K sector hard drive? e.g. incompatibility? Anything else we should know about 4K sectors?

  • HTC Android Messages - adding contact from SMS

    - by Chris

  • Optimal Disk Setup for OLTP SQL Server

    - by Chris
    We have a high transaction (lots of reads and writes) database server (running SQL 2005) that is currently set up with a RAID 1 OS partition (C:) and a RAID 5 data/log/tempdb partition (D:). The C: has 2 drives and the D: has 4 drives. The server has around 300 databases ranging from 10MB to 2GB in size. I have been reading up on best practices for partioning the disks, but would like some opinions on our setup since we are so limited in the number of disks. It seems like RAID 10 is popular, but I dont think we could use it with only 6 total disks to work with. Thanks. Update I went with 3 RAID 1 Partitions (2 disks each) Partition 1: OS, TempDB, Backups Partition 2: Logs Partition 3: Data

  • What's a good Text Expander software for windows?

    - by chris.w.mclean
    What's a good text expander out there for windows? Ideally it needs to work w/ MS Word, needs to be configurable in how it gets triggered, (i.e. the string hdt when followed by a space gets transformed into Help Desk Ticket, but hdt gets ignored). And needs to have an import option where a large list of tags & expansions can be loaded. Plugins for UltraEdit/Notepad++ would also be acceptable.

  • How can I change the subject of messages on an Exchange server automatically?

    - by Chris R
    I want to do something more than just normal mail - folder rules; I want to put a layer in front of my exchange server that lets me, for example, rewrite subjects into a more readable form. I get automated messages whose subject format makes them almost useless. Changing the emitting software is not going to happen, so I need to do something client side. I'm interested in anything that would allow me to do this, either on a mac, or on an older linux distro. Preferably the latter, and preferably in a way that I can turn on and forget about.

  • How to allow unprivileged apache/PHP to do a root task (CentOS)

    - by Chris
    I am setting up a sort of personal dropbox for our customers on a CentOS 6.3 machine. The server will be accessible thru SFTP and a proprietary http service base on PHP. This machine will be in our DMZ so it has to be secure. Because of this I have apache running as an unprivileged user, hardened the security on apache, the OS, PHP, applied a lot of filtering in iptables and applied some restrictive TCP Wrappers. Now you might have suspected this one was coming, SELinux is also set to enforcing. I'm setting up PAM to use MySQL so my users in the web application can login. These users will all be in a group that can use SSH only for SFTP and users will be chrooted to their own 'home' folder. To allow this SELinux wants the folders to have the user_home_t tag. Also the parent directory needs to be writable by root only. If these restrictions are not met SELinux will kill the SSH pipe immediately. The files that need to be accessible thru both http and SFTP so I have made a SELinux module to allow Apache to search/attr/read/write etc. to directories with the user_home_dir_t tag. As sftp users are stored in MySQL I want to setup their home dirs upon user creation. This is a problem since Apache has no write access to the /home dir, it's only writable by root since it's required to keep SELinux and OpenSSH happy. Basically I need to let Apache do only a few tasks as root and only within /home. So I need to somehow elevate the privileges temporarily or let root do these tasks for apache instead. What I need to have apache do with root privileges is the following. mkdir /home/userdir/ mkdir /home/userdir/userdir chmod -R 0755 /home/userdir umask 011 /home/userdir/userdir chcon -R -t user_home_t /home/userdir chown -R user:sftp_admin /home/userdir/userdir chmod 2770 /home/userdir/userdir This would create a home for the user, now I have an idea that might work, cron. That would mean the server needs to check for users that have no home every minute, then when creating users the interface would freeze for an average of 30 seconds before the account creation can be confirmed which I do not prefer. Does anybody know if something can be done with sudoers? Or any other idea's are welcome... Thanks for your time!

  • How do I get rid of com.apple.launchd.peruser errors in my log?

    - by Chris R
    I'm getting repeated errors in my console log that look (basically) like this: 10-09-29 10:06:08 AM com.apple.launchd[1] (com.apple.launchd.peruser.501[51581]) getpwuid("501") failed 10-09-29 10:06:08 AM com.apple.launchd[1] (com.apple.launchd.peruser.501[51581]) Exited with exit code: 1 This machine was set up using the migration assistant, from a machine where my UID was 501, but here it's 505. I have the same username and group set, of course, but... So, where is this peruser launchd tool configured, so that I can disable the daemons that are causing this error message?

  • Excel wizardness needed - Group By, Sort, Count function help

    - by Chris
    Riddle me this: You have 3 part numbers with the same part name xyz, each with a quantity of 10 items. The items can be picked during the day or week, therefore changing the amount of items on hand. I know I need to use the group by, sort, count and perhaps sumif formulas to have a running count of the number of items on hand at the end of each day (which could be positive or negative). Help? it wont let me add an image because i'm a new user. 'Oops! Your edit couldn't be submitted because: * we're sorry, but as a spam prevention mechanism, new users aren't allowed to post images.

  • Using SQL Server profiler from 2008 against R2 database

    - by Chris Lively
    On my dev machine I have the management studio tools installed from SQL Server 2008. However, one of the sql server boxes I need to profile against is running R2. Because of this, when I start the profiler and connect to that server all of the templates are gone. If I go to Edit the templates, the R2 server type isn't available as an option. Do I have to upgrade my local toolset to R2 or is there some other way around this? Note, that if I create a template and save it the next time I connect to the server that saved template isn't available.

    I'm trying to setup mutt wiht gmail for the first time. It seems to work pretty well, however when I send a mail from Mutt i appears twice in Gmail's sent folder.

  • Using IP Tables to deny packet patterns?

    - by Chris
    I'm not experienced with IP tables but it's something I'll be looking into if this is plausible. I'm looking to set up a system to inspect packets and look for a pattern similar to korek's chop chop attack. Is there a way to set up the IP tables to defend against this attack? Thanks

  • Fixing Master Boot Record From Linux After Windows Corrupts It

    - by Chris S
    I bought a Dell Inspiron 1545 laptop, and setup Ubuntu 10.04 to dual boot alongside Windows 7. Regrettably, when activating the wireless, I did something in Windows 7 that caused it to overwrite or corrupt the master boot record, so now when I reboot I get the message "No bootable devices found". Is there an easy way to fix this, perhaps via a Linux LiveCD, or do I have to wipe out everything and reinstall?

  • Ubuntu 9.04: Ripping CDs with grip?

    - by chris
    I tried to rip a CD tonight, and couldn't figure out how to configure grip - /dev/cdrom doesn't seem to be the mount point for music CDs any more. How can I configure grip to find CDs? Update: /etc/fstab has /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0 But there's nothing visible in /media/cdrom0 (or /media/cdrom, which is a symlink to cdrom0) There's an icon on the desktop labeled "Audio Disk" and opening it shows the .wav files on the CD. The location is cdda://sr0/, but grip doesn't like that either. Trying to manually mount /dev/sr0, I get $ sudo mount -t auto /dev/sr0 foo/ mount: block device /dev/sr0 is write-protected, mounting read-only mount: you must specify the filesystem type Update 2: Tried to change the media handling preferences (From a file browser, Edit-Preferences, Media, CD Audio) to "Do Nothing". CD Still doesn't mount. Update 3: With an audio CD in the drive: $ ls -l /dev/ | grep cd lrwxrwxrwx 1 root root 3 2009-09-15 22:13 cdrom1 -> sr0 lrwxrwxrwx 1 root root 3 2009-09-15 22:13 cdrw1 -> sr0 drwxr-xr-x 2 root root 60 2009-09-15 22:13 pktcdvd lrwxrwxrwx 1 root root 3 2009-09-15 22:13 scd0 -> sr0 crw-rw----+ 1 root cdrom 21, 2 2009-09-15 22:13 sg2 brw-rw----+ 1 root cdrom 11, 0 2009-09-15 22:13 sr0

  • Printing on Windows 8 64-Bit through Windows Server 2008 (32 Bit) RemoteApp

    - by Chris
    We have a network where our server is running on Windows Server 2008 (32 Bit) and a client computer is running on Windows 8.1 (64 bit) with a local printer attached to the client. The printer is an HP P1006. The remote app works well but when trying to print we get an odd "error 545". We have tried both using the "connect client printer" function in remoteapp and also making the printer shared over the network and printing to it via the network from within the remoteapp. Nothing works. We can print a test page from the server to the client computer just fine, but it seems from remoteapp we cannot. We have also tried installing the 32 bit drivers on the 64 bit machine as both the primary and secondary drivers but cannot get them to install. Suggestions please? We've been going crazy over this issue.

  • How do you close a VMWare Fusion VM Window without shutting it down or suspending it?

    - by Chris
    There are a few parts to this question. The first is: I'm running a virtual machine guest using vmrun and nogui, when I open the VMWare Fusion application, the window library opens but subsequently also opens any window of a running VM. Is there a way to prevent this? Secondly, but related: Once it does pop up or I have that separate VM Window open, is there a way to close the window such that it does not suspend or shutdown the vm i.e. convert it back to nogui mode?

  • Mouse wheel does not work in Excel 2007

    - by Chris Noe
    I am running Office 2007 on Windows XP-SP3. My mouse wheel works fine in other applications, meaning that it scrolls information up and down when the mouse is positioned over a given panel. It's even working fine in the other Office 2007 apps, so this is not a hardware or driver problem. It doesn't help to click on a cell to give the worksheet focus. I've tried various Advanced options that people recommend, to no avail: Allow editing directly in cell Zoom on roll with IntelliMouse What the heck, has Microsoft disabled this most useful functionality?

  • How can I change the binding order of network adapters in Windows 7?

    - by Chris Farmer
    The end goal here is that I am trying to install an Oracle 10g server on my Windows 7 x64 dev box. I use DHCP, and the Oracle installer is throwing up this warning: Checking Network Configuration requirements ... Check complete. The overall result of this check is: Failed <<<< Problem: The install has detected that the primary IP address of the system is DHCP-assigned. Recommendation: Oracle supports installations on systems with DHCP-assigned IP addresses; However, before you can do this, you must configure the Microsoft LoopBack Adapter to be the primary network adapter on the system. See the Installation Guide for more details on installing the software on systems configured with DHCP. I have installed the loopback adapter, but I am not sure how to make it the primary network adapter. I see this Microsoft KB article on the subject but it's Windows XP-oriented, and I can't seem to find a comparable one for Windows 7. Some of the options it talks about don't seem to be present in the views of the adapters that I see. So, how can I make the loopback adapter become the primary adapter?

  • Can't start firewall or automatic updates in Windows XP

    - by Chris Porter
    On a friends laptop following some viruses infestations there is a problem in starting the Windows firewall. The error is: Could not start the Windows Firewall/Internet Connection Sharing(ICS) service on Local Computer. Error 2: The system cannot find the file specified When attempting to turn on automatic updates in the security centre, the message is: We're sorry. The Security Center could not change your Automatic Updates settings. To try changing these settings yourself, go to System in Control Panel. On the Automtic Updates tab, select Automatic (recommended), and then click OK. All the options under "Automatic Updates" are greyed out. I've tried the suggestions below and many others: http://windowsxp.mvps.org/sharedaccess.htm http://support.Microsoft.com/kb/892199 http://windowsxp.mvps.org/repairwmi.htm I can't do a repair install because the installer doesn't detect existing versions. It's XP pro service pack 3.

  • 403 Forbidden serving static files from VirtualBox shared folder with nginx (Ubuntu 10.04LTS guest, Windows 7 host)

    - by Chris Pratt
    I'm working on a local development VM and trying to test serving my site with gunicorn and nginx as a reverse proxy for static resources only. The site loads minus static resources with user nginx; in nginx.conf. Attempting to load a static resource individually reveals a 403 Forbidden error. For background. The static resources are in a shared folder under /media/sf_work. All files are owned by root:vboxsf (VirtualBox default). My user account on the system has been added to the vboxsf group, and I have full access to the shared folder. For comparison, I tried changing the nginx.conf user to my user account. In that scenario, the static files did load, but then the homepage itself gives a 403 Forbidden error. So, I then tried adding the nginx user to the vboxsf group, but then everything gives a 403 Forbidden error. After further investigation it seems that if the nginx.conf user is in any group, it results in a 403 Forbidden. Any idea what could possibly be going on here?
