What is the maximum power consumption of a graphics adapter with an ATI Radeon X850 Pro GPU?
Proofs via sources (downloadable manuals) would be appreciated.
I did something weird and now my text size is like 3pt on every system window, but when I go in and change my window fonts to larger to something that looks normal, it makes my clock, bash, and other fonts absolutely gigantic. Is there any way I can just roll back my system and it's settings? It wouldn't be much bother as I installed the OS yesterday. I'd hate to have to reinstall entirely though, but I guess it's an option.
Hi all,
when I try to copy any file with scp on Mac OS X Snow Leopard from another machine I get this error:
scp [email protected]:/home/me/file.zip .
Password:
...
---> Couldn't open /dev/null: Permission denied
this is the output of "ls -l /dev/null":
crw-rw-rw- 1 root wheel 3, 2 May 14 14:10 /dev/null
I am in the group wheel, and even if I do "sudo scp..." it doesn't work. It's driving me crazy, do you have any suggestion?
Thanx!
Hi.
I need to install firefox on 100+ machines, I've done a few manually but its too much of a task to do the whole lot. I need to :
Install firefox executable
Set "dont import anything(from Internet Explorer)"
Set default browser to "no"
Set default browser not to check again
Copy a shortcut onto the desktop that goes to a specific URL
I know this should be able to be implemented with an MSI package, but could I also set those settings?
Thanks
My computer has been acting up when I play games so I wanted to look into why.
Issue 1: GPU Temp
According to afterburner and speedfan my 8800GTX idles at 90 degrees and then when playing games shoots up to over 110C which is when my graphics basically starts to give rendering issues.
Issue 2: CPU Temp
Speedfan is saying my CPU temp is 83C idle but when I look at core temp it says core0 is at 35C and core1 is at 33C.
Issue 3: Voltages
This is what speedfan is saying for my voltages:
Vcore1: 1.01V Vcore2: 1.90V
+3.3V: 3.31V
+5V: 4.95V
+12V: 0.51V
-12V: -16.80V
-5V: -8.43V
+5V 5.13V Vbat: 3.25V Vcore: 3.00V
+3.3V: 3.20V
These voltages, for lack of a better word, look f*cked. With all this happening, the computer runs ok under normal use. Is the software giving out incorrect readouts or instead should I immediately move the computer into another room before it explodes?
P.s I would like to add this is a stock system. EVGA 8800GTX, E6850 CPU, 800W PSU
Is there a way to change an i386 RHEL4 machine to run an amd64 kernel, but ensure that it still builds software into same i386 binaries?
On Debian this seems quite straightforward: just install an amd64 kernel (worst case, build one like this guy:
http://www.debian-administration.org/users/jonesy/weblog/1) and prefix everything with "linux32". Then everything that considers uname -m will be unchanged, I just need to handle the few cases that consider uname -r.
What is the Red Hat equivalent? Is the only way a full 64-bit installation on another disk and then chrooting back to the 32-bit system before anyone builds anything? (Even the best examples of that seem to be Debian-based.)
Background: We make a large system that runs on (a variant of) i386 RHEL4. However, some of the larger RHEL build machines now have enough RAM that they might benefit from going 64-bit (for the kernel and maybe some of the bigger build steps). Our build system doesn't support cross-compilation.
Hi,
When I buy CD's I tend to rip them to FLAC right away. When ripping I use Foobar2000 or Exact Audio Copy and enable secure ripping which uses error correction. Recently I bought a 2 CD compilation album brand new but when I tried to rip the second CD on my laptop using Foobar2000 it struggled with the last 2 tracks and was unable to finish. EAC was also unable to get an accurate rip and reports read errors. Ripping in fast mode results in audible errors in the output track.
I have tried another computer and having similar problems. I cannot see any damage to the disc and it has not been dropped or anything.
The weird thing is that I had similar problems with a different album and different PC a while back. This other CD was a compilation disk so it was also right up to the CD capacity limit and again it was the last few tracks that would not rip. Dozens of other discs have ripped fine
So I am wondering if the CD is simply defective, or whether it is something else. How common are defective CD's? Do some CD drives struggle with CD's of this capacity? Or Is this some kind of copy protection?
I'm thinking of asking Amazon for a replacement but it would be annoying if I get the same problem again.
When we add computers to the domain in Windows 7, we get the error:
Changing the Primary Domain DNS name of this computer to "" failed.
The name will remain "domain.com".
The error was:
The specified server cannot perform the requested operation.
This happens on multiple computers and retrying yields the same result. Despite the error, the computer is still able to login to the domain ok. The DCs are windows 2003.
Has anyone found a way to get rid of this error?
Any help is appreciated.
I've acquired a Sheevaplug running - I think - Ubuntu. I'd like to mount an external USB hard drive, but I don't know the name of the device that needs mounting.
When I list the devices under /dev, a long list is produced.
How do I find out which device listed needs to be mounted?
Update:
When I run dmesg after plugging the device in, I see the following at the end:
usb 1-1: new high speed USB device using ehci_marvell and address 6
usb 1-1: device not accepting address 6, error -71
usb 1-1: new high speed USB device using ehci_marvell and address 7
usb 1-1: device not accepting address 7, error -71
usb 1-1: new high speed USB device using ehci_marvell and address 8
usb 1-1: device not accepting address 8, error -71
usb 1-1: new high speed USB device using ehci_marvell and address 9
usb 1-1: device not accepting address 9, error -71
And when I view /var/log/messages, I can see this:
Sep 23 21:26:03 debian kernel: usb 1-1: new high speed USB device using ehci_ma$
Sep 23 21:26:04 debian kernel: usb 1-1: new high speed USB device using ehci_ma$
Sep 23 21:26:05 debian kernel: usb 1-1: new high speed USB device using ehci_ma$
Sep 23 21:26:05 debian kernel: usb 1-1: new high speed USB device using ehci_ma$
Unfortunately, I don't know what these mean.
My laptop uses CentOS 6.3 with kernel 2.6.32-279.el6.x86_64. My wireless adaptor is Intel Corporation Centrino Wireless-N 1000.
My wireless connection always get off after about 20 minutes. The network applet shows the connection is still on with good signal strength, but I just cannot load any web pages even the configuration page of the wireless router.
The problem will continue until I disable and reconnect the wireless.
Other devices like my cell phone uses the same wireless network without the problem. Even yesterday I'm using the same laptop with Fedora 17 without this problem.
I also searched the internet and someone said running services NetworkManager and network simultaneously may be a problem. But I cannot stop any one of them because: if I stop network and start NetworkManager, the network service will start automatically; if I stop NetworkManager and run network, it says "Device does not seem to be present, delaying initialization." when trying to bringing on the wireless.
What shall I do to get rid of the problem? Thank you very much!
I am developing a REST API which I want to secure with SSL/TLS. I have implemented a large part of the API which I have tested over HTTP, however, I am now at the stage where I want to switch it over to use HTTPS.
At the moment the API is hosted on a Windows XP professional SP2 box running IIS 5.1 (development environment only) and I used the SelfSSL.exe tool from the IIS 6.0 Resource Kit Tools to generate a server certificate. I then configured my API to use this certificate which all appeared to work fine as I attempted to connect to my API using HTTP and I get a 403 response saying "... must be accessed over a secure channel...". However, the problem is when I attempt to access the same the API over HTTPS it just appears to hang!
As this is a development environment at the moment I don't have a domain name (just a static IP address) and the API is running on port 81. Also (incase it matters) the API is the default site (I replaced it).
Any ideas why I can't connect using HTTPS?
My computer freezes for about 30 seconds, this happens occasionally. When it happens I can still move the mouse, sometimes even alternate between tabs in google chrome. If I try to open windows explorer nothing happens. Also chrome rapports "waiting for cache". It also happens in starcraft II, during which the sounds loops.
I have made a Trace as this topic describes:
How do I troubleshoot a Windows 7 freeze or slowness?
Trace:
https://docs.google.com/open?id=0B_VkKdh535p6NklhSDdBLURUMnc
I have looked at it, but I couldn't figure it out.
My system specs are:
AMD Athlon X4 651
Asus Ati HD6670
ADATA SSD sp900
Asus f1a55 mainboard
4 GB crucial 1333 ram
500 watt atx ps
I'm running Windows 7, fully updated.
Any help is much appreciated.
Update:
I tried something before your reply that may have helped the problem. I don't know for sure if it has, it's too soon to tell.
A bit of history first. I had problems installing win7 on my ssd from the start. In IDE mode it worked, but I had the same problems as above. AHCI was a total fail, with it on before install as well as turning it on after install (including tweaking register). I didn't bother installing the AMD chipset/AHCI as it was reported to have no TRIM function and thus make problems worse.
Eventually I did install the AMD SMbus driver as the stability issues were driving me crazy. It worked, no more issues, until I installed some extra drivers and software. Audio/LAN/ASUS suite, I don’t see the relation, but somehow it screwed up my system again. As a last effort I posted here on this site. After which the thought occurred to me turn on AHCI again as by now I had all necessary drivers installed anyway. (plus all windows updates downloaded/installed in the meantime)
I did and stability didn’t seem great the first few reboots, but eventually everything seemed to work great. I tried to play starcraft II – an almost guaranteed freeze before – and I had no problems. I’m basically crossing my fingers and hope the problem is gone for good.
I still think it has something to do with my SSD. In my research into the problem I noticed a lot of these issues with sandforce 2281 firmware, the exact same firmware I have. People reported the same problem that I had, freezes. Additionally they reported that during a freeze the hdd light stayed on, I noticed after I read this that this happened with my computer as well. None of this is conclusive evidence that my SSD is really to fault, but it is suspicious.
And why turning on AHCI would fix it I don’t know.
Thank you Tom for taking a look, if the problem returns I will certainly do what you advised.
I have a server, 4 PC's, a network printer, a switch and an ADSL modem. Currently the server runs Red Hat 9 and sits between the internet and the other PCs like in
http://upload.wikimedia.org/wikipedia/en/1/12/Sample-network-diagram.png
I have bought a new server PC to replace the old one, and I plan to install Fedora Core linux on it. The server acts as web and file server. The PCs all run Windows.
Alternatively, I could connect the new server and all PCs to the switch, and connect the switch to the modem. (Sorry, couldn't find an image.)
What are the pros and cons of these network layouts? Eg. in terms of reliability, security and flexibility?
I am not a Linux guru but know of (and am not afraid of) iptables, dhcpd et al.
Thank you for any tips, pointers and links.
I want to change the default directory so that someone can't just go to my server.com/cpanel or server.com/whm and start trying to access my system.
Any tips? Webserver is Apache2
So my MacBook Air keeps dropping Wi-Fi for some reason. It happens ONLY on my home network, and ONLY to my computer. I'm using a Linksys WRT54G router. I'm the only Mac on the network. Every other Wi-Fi network is perfectly fine, and every other computer on this network is fine. Many things can happen. It could say it's connected, but not be able to access the internet (whether it tells me that there's no internet access or not). It may just drop Wi-Fi altogether, and refuse to connect.
Generally, if I unplug the router and plug it back in, it's all good. It also works if I restart my computer. This happens multiple times a day. Yesterday I did everything I know to get it to connect (restart router many times, restart my MacBook), and nothing worked. Eventually it just magically worked.
How can I stop this from happening? We got a notice from Comcast a while ago saying that a bot called DNS Changer was detected on one or more machines on the network. I'm assuming that this can't be me, right?
I have recently implemented LastPass as a secure password manager. When I changed the password for my email address an associated account ([email protected]) that i had never seen before came up in association with my account. It asked me if i wanted to change password for my account and the "smithfaketester" account I used Google to try and find out what is going on, but came up empty. I am afraid my computer is bot net-ed. Any input is greatly appreciated.
I have used google to search for reasons why this fake account was coming up but I did not find any meaningful info.
I am having problems booting a new Ubuntu 10 (server) install. My primary HD (/dev/sda) is laid out as follows:
Device Boot Start End Blocks Id System
/dev/sda1 * 1 18 144553+ 83 Linux <-- /BOOT
/dev/sda2 19 182401 1464991447+ 5 Extended
/dev/sda5 19 2207 17583111 fd Linux raid autodetect
/dev/sda6 2208 11934 78132096 fd Linux raid autodetect <-- / (ROOTFS)
/dev/sda7 11935 182401 1369276146 fd Linux raid autodetect
The rootfs is part of a RAID1 (software) array (currently degraded):
# cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md2 : active raid1 sda6[1]
78132032 blocks [2/1] [_U]
The UUIDs for the partitions are as follows:
# blkid /dev/sda1
/dev/sda1: UUID="b25dd301-41b9-4f4d-9b0a-0e31713dd74c" TYPE="ext2"
# blkid /dev/sda6
/dev/sda6: UUID="af7b9ede-fa53-c0c1-74be-31ec752c5cd5" TYPE="linux_raid_member"
# blkid /dev/md2
/dev/md2: UUID="a0602d42-6855-482f-870c-6f6ecdcdae3f" TYPE="ext4"
Finally, I have my grub2 menuentry setup as follows:
### BEGIN /etc/grub.d/10_linux ###
menuentry 'Ubuntu, with Linux 2.6.32-25-server' --class ubuntu --class gnu-linux --class gnu --class os {
insmod ext2
insmod raid
insmod mdraid
set root='(hd0,1)'
search --no-floppy --fs-uuid --set b25dd301-41b9-4f4d-9b0a-0e31713dd74c
linux /vmlinuz-2.6.32-25-server root=UUID=a0602d42-6855-482f-870c-6f6ecdcdae3f ro nosplash noplymouth
initrd /initrd.img-2.6.32-25-server
}
When I attempt to boot, grub loads OK, however I eventually get the following error message:
Gave up waiting for root device. ALERT /dev/disk/by-uuid/a0602d42-6855-482f-870c-6f6ecdcdae3f does not exist. Dropping to a shell!
If from the grub bootloader I open a grub command line, I can ls (hd0,) and it lists the correct partitions with the UUIDs as shown above - sda6 shows 'a0602d42-6855-482f-870c-6f6ecdcdae3f' (the RAID UUID). If I ls (md2)/ it properly lists all the files on the RAID1 filesystem (ext4) so it doesn't appear to be an issue accessing the raid device.
Does anyone have any suggestions as to what the problem might be? I can't figure this one out.

Sounds a bit confusing, doesn't it?
I've created an 'events calendar' in Excel for my local area. Each date throughout the year is assigned to a row.
What I want to do is, when I enter an event for a particular date, then automatically create an entry elsewhere in the calendar for an action to be taken.
So for example, There's an event on the 30th July, so I enter it into the calendar. I'd like to be able to specify that an entry should be made 4 weeks earlier, on the 2nd July, to tell me to blog, tweet or whatever about that particular event.
Can Excel help me to do that and if so, what do I need to do?
A few months ago I enabled password protection on my MongoDB install. Today I ran the Mongo client and forgot to use my login details. Instead of rejecting nearly everything I try to do from the shell, like it should, I had complete access to all the databases and collections. Fortunately this instance is only running a few test apps, so I quickly shutdown the MongoD instance until I figure this out.
Has anybody ever seen this kind of behavior before and knows what is going on? The MongoD instance is running on a Linux VM hosted by Azure. The only thing I can think of is that perhaps Azure restored an old copy of the VM, but I received no E-mails to that effect and everything else on the server seems to be proper, including new daemon processes that I added after I enabled password protection on MongoD.
I recently tried opening one of my Python projects with CMD to see what would happen. The result did nothing amazing, but Windows 7 thought I wanted to open .py files in CMD all the time. I have tried everything, setting it back to python.exe does not work, I even went to Control Panel to see if it could help, but Control Panel couldn't help either. So if someone could help me please that would be great. Thank you.
Scenario I'd like to use:
I want to have two fields in a Word document. I would like to enter a date in the first one. Then I want the second one to display a value based on the date I entered in the first field.
Is there support for this kind of scenario in Office Word 2007?
I looks on the web but couldn't find any useful info. I did find info about formula support but not for this kind of scenario.
