• Why my new GTX 660m's clock drops drastically after running few seconds

  - by trVoldemort

  I bought a Lenovo Y580 laptop few days ago, this model is equipped with GTX 660m graphics card. However, the game performance is unbelievably poor since it out from the box. I realized there is something wrong with this graphics card. I downloaded GPU-z, and did a simple test. And I was shocked by the fact that my GTX 660m graphics card is running at 135.0mhz core clock. (It should be 835mhz at least!) Even the integrated graphics card "Intel HD graphics 4000" can run at 650mhz. Further examining showed that in the first few seconds GTX 660m was actually running at 835mhz, however the core temperature quickly reached 90+°C and the clock (maybe) automatically drop to 135.0mhz. This is very strange. Anyone has any idea what's going on here?

• small light laptop with docking station that has a PCI(e) slot

  - by laramichaels

  Hi everyone, I am looking for a new laptop/netbook and I have two simple requirements: must be small (10-12in screen) and light (<=3-3.5pounds); must work with a dock into which I can put a PCI or PCI Express card. Basically, I have no performance requirements. Discontinued or low-end are fine. All I want is something easy to carry that when at work I can use a PCI/PCI Express card with to do multi-head. Eg, if an Acer Aspire 1410 fitted the second requirement I would by one in a blink. The only solution with which I am acquainted are Thinkpads that can go into the Thinkpad Advanced Dock. Do other laptop (or netbook brands) also offer the possibility of using Although this is not a "requirement" per se, I would rather hear about options that would not involve buying the latest-greatest-+$2k model... : ) Thank you for any advice! ~lara

• Set WordPress permalinks directly in httpd.conf?

  - by songdogtech

  Is is possible to configure WordPress permalinks directly in Apache httpd.conf? I have a server situation (Apache 2.2.3 CentOS PHP5.1.6) where I can't use .htaccess for performance reasons, but can use httpd.conf. The admin says that mod_rewrite is enabled, but AllowOverride is not, and I can't change those settings. And I need to restrict the permalinks to just the "blog" directory. This is what would go in .htaccess but needs to go into httpd.conf: <IfModule mod_rewrite.c> RewriteEngine On RewriteBase /blog/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /blog/index.php [L] </IfModule> Thanks...

• Is a matching entry in /etc/hosts required for hostname?

  - by JohnWoltman

  I was installing a Tomcat webapp that refused to work until I stumbled on someone else's issue with an unrelated product. The solution was to add the machine's name to /etc/hosts, to match the name returned by hostname. Is this required for general Linux networking to function correctly? My webapp is running in a virtual machine so that I can test the webapp, and I don't normally bother with the /etc/hosts file on VMs. I just shook my fist and cursed Tomcat and webapp's behavior. I read http://serverfault.com/questions/118823, but that doesn't say if it's required or not.

• How to create basic load balancer?

  - by Ilya Rusanen

  guys. I'd like to deploy my app on two different servers, located in US and Germany. As I suppose, I need to set up some kind of load balancer, that would deternime from which country my user is, and resolve it to US/Germany server. The general aim is to provide user abitiliy to work with the closest server (CDN is not a solution, 'cause we dont share static content). Where should I place load balancer that would resolve user to USA/GER severs? In usa/germany? What shold it look like? A usual server with some specific app or what? Thank you.

• wbadmin incremental system state backup

  - by user74513

  I am doing system state backups on a Windows Server 2008 R2 Enterprise (Service Pack 1) machine and expected the backups after the first one to be incremental. However with each backup a new directory with vhd files are created and the vhd files are almost the same size as the with the first backup. So the backups does not seem to be incremental. I used the following command to do the backup: wbadmin start systemstatebackup -backupTarget:f: I played around with the settings under "Configure Performance Settings" in the Windows Server Backup plugin in Server Manager but according to the description at the top of the dialog these settings are not applied to system state backups. Are there any settings available for wbadmin system state backup to make the backups incremental?

• Migrating SBS 2003 to 2012 standard

  - by AryaW

  My company is currently trying to migrate a Windows Small Business Server 2003 to Windows Server 2012. We know the general procedure, but we want to make sure we aren't going to mess anything up tremendously. Here's the steps we were planning on taking: 1. Uninstall exchange 2. Remove legacy GPO's 3. Demote the domain controller 4. Promote the new server to the primary domain controller. We have no mail servers to worry about. My question is, will the above method work or will we need to make a complete new domain? Thanks!

• What are the limitations of virtual machines?

  - by j-g-faustus

  I'm considering setting up a virtual machine running Windows, with Ubuntu 10.10 as the host OS, for those cases where I have a Windows-only program. I understand that using a VM will lose some performance, but are there other limitations to what the OS in a virtual machine can do compared to "running on bare metal"? For example: Can a VM play games, like Dragon Age Origins or Civilization V? (Possibly with poorer framerates and/or lower resolution, but does it play at all?) Can a VM rip DVD/Blue-ray using AnyDVD or similar Windows program? Can a VM handle new hardware that requires dedicated drivers, but the drivers are only available for the OS running inside the VM? (Ex. graphics card, digital camera, card reader for smart card authentication.) Is it possible to say anything about "general limitations" of VMs, or is this wholly dependent on the specific VM?

• XKB - remap arrow keys and preserve shift behaviour to select text

  - by dgirardi

  I realize arrow key remapping is an old problem, however I cannot seem to find a good solution that lets me select text with SHIFT + remapped keys as I would do with the vanilla arrow keys. For instance, if I remap Caps Lock to ISO_Level3_Shift and set xkb_symbols to read either key <AC08> { [ k, K , Down, Down] }; or key <AC08> { type="THREE_LEVEL", [ k, K , Down ] }; Pressing Shift+CapsLock+K will behave exactly as CapsLock+K (while Shift+Down behaves differently from Down alone). I had somewhat more success using higher level macro utilities and generating keyboard events (i.e. generate both the shift and the arrow keypresses); hoever that approach has a whole set of different problems - often the UI response to a simulated keypress is different from the "real" keypress, and there are performance problems as well - I can type faster than the thing can handle. Tl;dr; how can you shift-select using remapped arrow keys under X?

• How to ignore query parameters in web cache?

  - by eduardocereto

  Google Analytics use some query parameters to identify campaigns and to do cookie control. This is all handled by javascript code. Take a look at the following example: http://www.example.com/?utm_source=newsletter&utm_medium=email&utm_ter m=October%2B2008&utm_campaign=promotion This will set cookies via JavaScript with the right campaign origin. This query parameters can have multiple and sometimes random values. Since they are used as cache hash keys the cache performance is heavily degraded in some scenarios. I suppose there's a not so hard configuration on cache servers to just ignore all query parameters or specific query parameters. Am I right? Does anyone know how hard is it in popular web cache solutions, to create ? I'm not interested in a specific web cache solution. It would be great to hear about the one you use.

• Elastic Load Balancer & SSL termination

  - by Aaron Scruggs

  I am setting up a Rails app on AWS that: 1) all traffic must ssl encrypted 2) will highly fluctuate in traffic on a weekly basis 3) will by maintained by someone that is a stronger coder than sysadmin, but will be responsible for both I am thinking that SSL termination on an elastic load balancer backed by small ec2 instances running nginx and unicorn A small subset of the requests will take longer than 10s, because of this I am also debating using 'thin' instead of 'unicorn'. My question is this: Is this sane? I am stepping into a quagmire of cost, maintainability, security or performance problems?

• Use one home directory for more than one operating system

  - by Just Jake

  I want to configure the same user account across multiple operating systems. Right now, I'm set up for general use in Mac OS 10.6.6 "Snow Leopard," and I have about 200gb of files in my home directory (/Users/justjake/). I want to use this user (and home directory) for other operating systems on other partitions. For example, I have Mac OS 10.5 installed on a 12gb partition. How can I share permissions, user accounts across my two operating systems? Would moving the my /Users directory from 10.6 to it's own partition then mounting it using /etc/fstab solve my issue?

• Wireless DHCP doesn't work until wired Ethernet plugged in

  - by MT_Head

  A client of mine has an Asus R1F tablet running Windows XP Tablet SP3. It has an Intel 3945ABG wireless card; wired Ethernet is a Realtek something-or-other. In the past few days, it's developed an odd problem: WiFi authenticates, but can't get an address via DHCP. plug in wired Ethernet - both interfaces get good addresses unplug cable, WiFi continues to work until shutdown. Next morning, repeat process. I've tried: turning WiFi off/on (there's a slider switch) disabling/re-enabling via Device Mangler uninstalling and reinstalling the driver for the 3945ABG... changing from Intel Pro/SET to Windows Wireless Zero Config (and back) restarting the router changing the static DHCP assignments at the router upgrading the router firmware, just on general principles The router/access point is pfSense 1.2.3RC1 (was 1.2.2); wireless card is Atheros-based. None of the 12 other users (5 with tablets) are having problems.

• Winamp question: I want to search through my songs by which playlists they're sorted into

  - by Daddy Warbox

  I'm trying to think of a way to do this. I sort my songs into a variety of playlists corresponding to different 'moods' I might have, but some songs fit for more than one kind of mood (e.g. a techno song might be 'stylish' and 'surreal', or something to that effect). I also give them different star ratings for a general sort of opinion about them. I want to be able to filter my media library by moods I want or don't want, as well as by star rating. Anyone have a good way to do something like this? Alternatively, is there a way to 'tag' my songs by mood and then search up by those tags? because then I could just dump the queried results into playlists as needed. Thanks in advance.

• Should I have a heroku worker dyno for poll a AWS SQS?

  - by Luccas

  Im confusing about where should I have a script polling an Aws Sqs inside a Rails application. If I use a thread inside the web app probably it will use cpu cycles to listen this queue forever and then affecting performance. And if I reserve a single heroku worker dyno it costs $34.50 per month. It makes sense to pay this price for it for a single queue poll? Or it's not the case to use a worker for it? The script code: queue = AWS::SQS::Queue.new(SQSADDR['my_queue']) queue.poll(:idle_timeout => 20) do |msg| # code here end I need help!! Thanks

• Aironet 1200's Auto-Channel Feature: When should it be used?

  - by Josh Brower

  In our building we have around 25 1200 series Aironets, with a bit of overlap in some areas. Up until this point, we have had them deployed in alternating 1/6/11 channels, but we are wondering if we would get better performance if we used the auto-channel select feature. In looking around, I have seen comments that this feature should not be used as the WAP does a channel scan only on the radio startup, but I have not found this in any Cisco docs. Anybody have anymore information, or real-world experience with this feature? Thanks! -Josh

• How to achieve reliable Gigabit Ethernet Link with my Acer Aspire Revo R3610?

  - by The Operator

  I want to stream HD movies over my wired Gigabit LAN from my PC to my Acer Aspire Revo R3610. It's connected with a 3ft Cat5e patch cable to my Netgear GS605v2 Switch. The PC acting as File Server is connected at 1Gbps to the Switch. Network driver options are set to defaults, including automatic speed/duplex negotiation on both machines. The Revo will not connect to my Network Switch at 1Gbps - the OS reports that it reverts to 100Mbps either shortly after connection or immediately upon connection. Through a process of elimination (trying different drivers, patch cables, ports on the switch, and other 1Gbps-capable devices connected to the Network switch which successfully achieve 1Gbps links and performance) I have drawn the conclusion there is either a Hardware or Software (Driver) issue with the Revo itself. I have performed tests using Windows 7 and Ubuntu 9.10. Can anyone offer insight on Gigabit Ethernet with the Revo?

• iis 7.0 output caching

  - by george9170

  My company is serving up deep-zoom maps. We have 100'000s jpg images being served up and was wondering if output caching would be the way to go. Our problem is latency on serving the images. I was wondering if i output caching would indeed improve latency and a general explanation about output caching. I have visisted http://blogs.iis.net/bills/archive/2007/05/02/iis7-output-caching-for-dynamic-content-dramatically-speed-up-your-asp-and-php-applications.aspx and was wondering if there are any other good sites to look at. thank you very much.

• Prevent Ultrabay HDD from ejecting on sleep

  - by Bryce Evans

  I have a lenovo T430s thinkpad with a small SSD primary drive and 500gb ultrabay drive. When I put the computer to sleep and then return, I get the message titled "problem ejecting < drive name " "Windows can't stop your 'Generic volume' device because a program is still using it." This pop up is very annoying every time every time I use the computer. I don't want to disable write caching [D:Hardware[drive]policiesquick removal] because I want best performance and never remove the drive. Any ways to avoid this pop up?

• 912 stream processor available in OpenCL

  - by tugrul büyükisik

  I am thinking of assembling this system: AMD CPU (A8-3870 APU which has Radeon HD 6550D inside: 400 stream processors:xxx GFLOPS) nearly 110$ AMD Graphics card: HD 7750 (512 stream processors:819 GFLOPS peak performance) nearly 170$ Appropriate ram (1600MHz bus) Mainboard What GFLOPS level can I reach as a stable mode with using OpenCL and similar programs? Can I use all 912 stream processors at the same time? I am not trying to do a VS question. I need to know what could be better for scientific computing (%75 of the time) and gaming (%25 of the time) because I have a low budget. With "scientific calculations" I mean fluid dynamics/solid state physics simulating; with games I mean those that need openCL and PhysX.

• What are the main differences between SRV records and TXT records?

  - by Chris Adams

  Hi there, I'm trying to consolidate domain names for the servers I look after to just use one panel instead of 3 or 4, and one thing stopping me is that the provider I originally wanted to move them to only lets me the following kinds of records: A MX NS CNAME TXT The first four I understand, but I'm not sure about the relationship (if any) between SRV records and TXT records. Can I use TXT records in the place of SRV records? They both seem to be general text records to just point at a particular server without needing to specify a particular protocol, so it doesn't sound like a totally unreasonable assumption, but I'd rather check here before I break something. If I can only set the above records, does that mean I'm essentially unable to so any SRC record redirecting? Thanks!

• Why is it a bad idea to use multiple NAT layers or is it?

  - by iamrohitbanga

  The computer network of an organization has a NAT with 192.168/16 IP address range. There is a department with a server that has an IP address 192.168.x.y and this server handles hosts of this department with another NAT with the IP address range 172.16/16. Thus there are 2 layers of NAT. Why don't they have subnetting instead. This would allow easy routing. I feel multiple layers of NAT can cause performance losses. Could you please help me compare the two design strategies.

• virtual machines and cryptography

  - by Unknown

  I suspect I'm a bit offtopic with the site mission, but it seems me more fitting for the question than stackoverflow i'm in preparing to create a vm with sensible data (personal use, it will be a web+mail+... appliance of sorts), i'd like to protect the data even with cryptography; the final choice have to be cross-platform for the host basically, I have to choose between guest system-level cryptography (say, dm-crypt or similar) or host level cryptography with truecrypt. do you think that the "truecrypt-volume contained virtualized disks" approach will hit the i/o performance of the vm badly (and therefore dm-crypt like approaches into the vm would be better), or is it doable? I'd like to protect all the guest data, not only my personal data, to be able to suspend the vm freely without worrying for the swap partition, etc

• Windows Experience Index Dropped After Adding Dedicated Graphics Card

  - by Ludo

  I purchased a new PC with a Gigabye Z68X-UD3H-B3. I had a Radeon HD 5450 graphics card spare, so I've added that instead of using the onboard graphics as I just presumed it would be better. But, my windows experience index has gone down. From 5.4 to 5. Dekstop Performance has dropped from 5.4 to 5, although gaming graphics has gone up from 5.9 to 6.2. I'm not actually going to be using the machine for gaming, just audio production, but I added the card as I'll possibly be doing video editing in future too. Why would this be? Can I trust windows experience index scores? Or is it possible the onboard stuff is just better for general desktop stuff? Thanks! Ludo.

• Determine/resolve filepath/alias of a certain command in the Windows command prompt

  - by porg

  How can I find out to which filepath (or alias) a certain command input will point to, in the Windows command prompt? Specifically Windows XP, info on other versions also appreciated! On Unix systems I simply use: $ which commandname /a/commandname Or: $ type -a commandname commandname is aliased to `/b/commandname' commandname is /a/commandname commandname is /b/commandname And I am simply looking for the equivalent in the Windows Shell (specifically Win XP). I came to this general question, from a specific issue: I had installed robocopy.exe (version 026), but the command line "robocopy" always triggers version 010, and I would like to determine where this command points to, in order to correct this mistake.
