• Problem with ubuntu 10.10 running from USB drive

  - by Surjya Narayana Padhi

  I recently downloaded Ubuntu 10.10 and created an USB drive with that. I started to run the Ubuntu from that USB drive. But I am facing so much problem. I am thinking why its not so much easy like Windows to do all my job in ubuntu. Always I get some error message or to install something. This time I am getting the following errors. I am trying to download and install Aircrack-ng. So used the command sudo apt-get install aircrack-ng. But the installation stops with the following error : update-initramfs: deferring update (trigger activated) cp: cannot stat `/vmlinuz': No such file or directory dpkg: error processing bcmwl-kernel-source (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: initramfs-tools bcmwl-kernel-source E: Sub-process /usr/bin/dpkg returned an error code (1) I don't even have the aptitude command installed till now. Are all these errors because of I am running the ubuntu from USB drive? Is there any simple and easy way to go to Ubuntu Software Center and download all the required essentials at one shot and then Aircrack-ng? I could not find the Aircrack-ng in Ubuntu Software Center Can anybody give me detail steps to solve all my problems above. I am frustrated searching for updates and installations. When something works and something does not work. Can anybody suggest me how I should proceed after installing ubuntu to run on a USB drive. So that I can use the OS like Windows. Like software download,wireless driver, sound, video, documents, C:, D: all things should be there. Please somebody help.

• How to boot XBMC 10.1 ISO on USB via grub?

  - by Shi

  I am trying to boot the XBMC Live image (http://xbmc.org/download/) as ISO from USB via grub 1.98. I have a Kubuntu 11.04 image there as well already and it works using the following configuration: menuentry "Kubuntu 11.04 64bit" { loopback loop /boot/iso/kubuntu-11.04-desktop-amd64.iso linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/boot/iso/kubuntu-11.04-desktop-amd64.iso noeject noprompt initrd (loop)/casper/initrd.gz } However, if I try to boot XBMC in an analogue way, I always get an error "Unable to find a medium containing a live file system". I found different approaches to install XBMC, but they all are about installing the distribution on USB, or using grub4dos, or unetbootin. I already found out that XBMC 10.1 is based on Ubuntu 10.04.2 LTS, so I tried those settings - even though they are quite similar to Kubuntu 11.04. Finally, the ISO contains a grub configuration as well in boot/grub/grub.cfg, but even with those parameters, I get the error above. My current configuration is the following one: menuentry "xbmc 10.1" { loopback loop /boot/iso/xbmc-10.1-live.iso linux (loop)/live/vmlinuz video=vesafb boot=live iso-scan/filename=/boot/iso/xbmc-10.1-live.iso xbmc=autostart,nodiskmount splash quiet loglevel=0 persistent quickreboot quickusbmodules notimezone noaccessibility noapparmor noaptcdrom noautologin noxautologin noconsolekeyboard nofastboot nognomepanel nohosts nokpersonalizer nolanguageselector nolocales nonetworking nopowermanagement noprogramcrashes nojockey nosudo noupdatenotifier nouser nopolkitconf noxautoconfig noxscreensaver nopreseed union=aufs initrd (loop)/live/initrd.img } Any more ideas or any more information I should supply?

• Getting a "CPU over temperature error", but temperatures seem to be normal

  - by Luis Parker

  I built a PC with the following parts: CPU: i5-2500 Motherboard: Asus P8H67-M EVO rev 3.0 RAM: G-Skill Ripjaws Series 8GB (2 x 4GB) DDR3 1333 Video: GTX 560-Ti 1GB I used a crappy (but functioning) old case and a 500W Powercooler supply. The rig also includes 3 HDs and a DVD-RW. Whenever I push the system mildly it resets right away (looks more like power off/power on) and gives me a "CPU over temperature error". However, BIOS always reports <65ºC for the CPU at the moment of the reset, same as Core Temp and RealTemp. This is RealTemp's log since launching BF3 until the reset (just over 1 minute, as you can see) Just to be sure I've checked the CPU cooler and re-applied the thermal paste twice, but nothing changed. I'm not overclocking at all. What am I missing here? Could it be that the old power supply is generating this error? Maybe the mobo isn't reporting temperatures correctly? I don't have a clue on how to troubleshoot this, help Thanks in advance!

• Windows 7 Media Center: sometimes no sound on a TV channel

  - by torbengb

  Problem Sometimes, recorded TV shows have no sound. This is of course very annoying because the recorded show is worthless. Also, when switching channels while watching live TV, sometimes a channel has no sound. This is always solved by switching channel again and then back (most often, once will do the trick). Media Center doesn't do this trick by itself when recording of course, so that's the bigger issue - but the cause is certainly the same. Details The computer is running a newly installed Windows 7 and Windows Media Center. It has 2 different tuner-cards installed. Both are installed with signed and up-to-date Win7 drivers and appear OK in Device Manager. Both tuners get the same antenna signal, from a split cable from the wall. The cable delivers analog cable TV (40+ channels) and digital cable TV (4 channels) at the same time. Both tuners have been configured to receive both analog and digital channels. This only happens with analog channels. How can I fix the no-sound problem? Update: I've now spent some time with the computer to try and pinpoint the problem, but I've had little success so far: I flipped through the channels until one didn't have sound, then I disconnected the antenna cable from one of the tuners. It was the right one because then the video also went away. I flipped lots more channels to see if the other card also would come up mute once but I never had a channel without sound. It might still be possible, I don't know. Then I disconnected the "good" tuner and connected the "bad" tuner and again flipped lots of channels but again I never had a channel without sound. It seems to me that the problem is erratic. It happens on any channel, and I haven't ruled out yet that it only happens on one tuner.

• Home Network Stopped Working

  - by James

  I have a home network where a machine running Windows 7 Ultimate N acts as a central hub for other devices to access media. This has been running for around 2 years now and there has been no recent configuration changes. The machine has a static IP address (192.168.0.3), which also has not been changed. A few laptops, Sonos music system and mobiles are using the machine for music/video mostly. Additionally, post 3389 was also open for RDP. I used a no-ip agent to map a hostname so I could RDP to the machine from the internet. As of yesterday when I try to ping the machine, I get PING:Transmit Failed, General Error I noticed however, the IP it is pinging is 0.0.2.233. All shares etc are no longer functioning including RDP. On the machine itself, an IP config shows like nothing has changed. It still shows the expected IP. If I ping itself from its hostname, I get the same error as above. machine has been rebooted, the router has been also. Any ideas where to even start on this?

• Linux Distro - GUI similar to Windows

  - by DeaconDesperado

  I am in the process of refurbing several older laptop machines for use by a couple college guys we have in training to learn basic web development in python. These are students who intern at my company and are hoping to do some work when the summer comes building simple client-oriented webapps (learning the basics of OOP, MVC webapp design in flask, etc.). We're trying to function as the "practical" side of their education. I would like to get them set up on these machines we have sitting about, but I'd like to use a linux distro that would have a gui that closely approximates what they are being compelled to use at school (windows.) I don't really have much of a preference as far as GUI goes since much of what we'll be learning together is accomplished on the command line. I just see this as an easier adjustment for them while they are still reliant on a graphical environment. In the past I'd go straight for Ubuntu, but since they started using the Unity GUI the responsiveness overall can be pretty clunky on older machines, especially since these machines (there are four of them) run the gambit on specs (though all are at least 1.0Ghz and none have anything better than basic integrated video.) Has anyone had to setup a similar working environment in Mint, bare Debian or Zorin? Thanks.

• External-Harddisk drive couldn't run unless in safe mode

  - by zfm

  This is the strangest thing ever happened to me... I have an external harddisk drive (ext-HDD), bought around 2 years ago (don't know whether this is an important issue or not). Here, I have a video file (.avi) in my internal harddisk dive (HDD), it worked very well, then I copy it to my ext-HDD, but I couldn't run the file directly from my ext-HDD! I tried to copy it back to my HDD (from the ext-HDD), and now the copy couldn't be run on my HDD too. Remember that I copy the file, so the original one was still there. I tried to go to safe mode (forget to mention, I use Windows 7 Pro), and this is where the strange thing happened, the copied files (both in ext-HDD and HDD) can be run in this safe mode. So, my question is, what could actually be happened there? PS: My ext-HDD is Axioo, 250 GB, exFAT... Edited: Currently I used MacOSX, and the file in the harddisk still can't be run. I haven't tried safe mode for Mac (is there one?), but will try later (if there is)

• Strange issue with 74.125.79.118

  - by Domenic

  I'm facing with a strange issue on a Linux server. After frequent crashes the analysis found that the server is led to collapse by a huge number of connections to the ip 74.125.79.118 departing from php scripts of the hosted web sites. After a depth analysis of the files I'm found that are not present any malware infections. Ip 74.125.79.118 is Google. I realize after a Google search that the connections to this ip are generated by embedded video from youtube on web sites, among other Google features like safe search. But I don't understand how this type of behavior can lead to the collapse the server and the uniqueness of the situation leads me to think that the situation is far from being attributable only to Google and Youtube. Also I've found that blocking connections from eth0 to 74.125.79.118:80 doesn't solve the issue but if I stop DNS traffic from eth0 to internet, connections to 74.125.79.118 stops. I'm really confused about this. Any suggestions? Cheers.

• How to diagnose issue between mobo, RAID, and SSD cache drive? [migrated]

  - by goober

  Background This issue is happening on my custom-built desktop. Relevant specs: Motherboard: ASUS P8Z68-V PRO Utilizing Intel RST technology (application that uses unused SSD as cache) Processor: Intel core i7-2600k (not overclocked) HDDs: RAID1 of 2x Seagate Barracuda 1TB (ST31000524AS) (RAID performed via z68 chipset) Machine has run fine for ~1 year with no issues, and has been well-maintained (dust, etc.) What Happened Random Freezing issues -- intermittent Looked at the RST application screen to see that the acceleration cache was listed as "unavailable" -- recommended that I power down and reconnect the drive. Reconnected the drive to no avail. Attempted to move the drive to another SATA port. Acceleration option disappeared from RST software. Now, the freeze happens whenever loading something particularly data-driven (a video, a game, etc.) Steps Attempted Reconnected the drive to no avail. Updated Intel RST software to v. 11.6.0.1030 to see if that made a difference. Attempted to move the drive to another SATA port. Acceleration option disappeared from RST software. Connected the drive as its own volume. Formatted it, ran disk check errors -- all seems fine. Reconnected the drive and selected it again as the cache drive. Now, what happens when there is a freeze: Machine freezes I am unable to perform any command Screen then goes black I hit the reset button During boot, all drives show as "Disabled" and I am told no volume can be found I then hit the reset button (or power off/on) again. Either the next time (or sometimes after repeating this once more), the metadata cache is reconstructed and the system boots fine, showing the SSD as a cache. Question I believe this is an issue with the SSD itself, but how can I be sure since connecting it separately appeared to show no problems? I want to make sure it's not an issue with the motherboard, SATA ports, etc.

• Surround in Windows 7 with Soundmax

  - by Henri

  Hey guys, I have a asus m2n motherboard with a Soundmax 1988 chip on it. I want to have surround sound in windows 7, but i cant get it to work. I tried a lot of different drivers, including the latest beta for Win 7. The problem is that when I configure the speakers and i do a "Test" all speakers work. But whenever I want to play some video or mp3, only the front speakers work. In vista there was this option called "Surround Fill" that would fix this problem, however, I cant seem to find that in windows 7. (The enhancements tab is completely gone for the speakers, other output devices do have that tab). Anybody knows the fix? Edit: I got it now kind of working by using a trial version of SRS AudioSandbox. However, the quality is quite bad since the program tries to create a real 5.1 of stereo sound. I just want to have stereo over 4 speakers instead of fake 5.1 over 4 speakers.

• Windows 7 automatically logs out when logging in

  - by Luke

  A Windows 7 HP x64 computer is set to automatically log in (no password), but once it starts logging in, it starts to load the desktop after the welcome screen, but before icons or background images are loaded, it goes to the Welcome screen saying 'Logging Off'. I can log in with Safe Mode, and I ran a couple different virus scans, with no detections. I also tried checking the userinit.exe file in System32 (as suggested by MANY users for Windows XP), but it's the same version as a working system. I also checked the registry under HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon for the SHELL and UserInit values, but they look normal. I tried to disable all startup items (through MSCONFIG) to select Diagnostic boot, but then I get a blue screen about the video driver not loading. Any other ideas? EDIT I created a new user, and it could log in no problems. I am thinking it's the NTUSER.DAT file. I just renamed it to NTUSER.DAT.old, then tried logging in as the problem user. I could log in, but as a TEMP profile. His profile folder is now C:\Users\TEMP, and his old folder is still accessible but in the wrong location. EDIT 2 I can't seem to turn off the TEMP profile, so I'm open to other suggestions. Copying the folders (i.e. Documents, Music, etc) does not work, as it creates an additional TEMP.000 then TEMP.001 folder each time the user logs in.

• Strange boot problems on 6 month old setup

  - by Balefire

  I've already exhausted my knowledge on this one, so forgive me if this post is a bit long. I built a computer 6 months ago for my wife and it worked fine until last week. Then it randomly shut down and would lock up while trying to boot on the boot screen. I cleared cmos and it allowed me to do startup recovery, but it "failed to fix the issue" so I reinstalled windows on the HD (moving the old install to windows_old). It worked, so I started installing drivers again, but then when I restarted to finalize installations it locked up again. This time, I took the hard drive and hooked it up to my computer, backed up all her files, and then formatted the hard drive before reinstalling it. (again had to clear cmos to let me boot from disk) It installed windows, I installed drivers, and it worked for a few hours but then died during startup again. So, then I got a new HD, cleared cmos, and installed clean again, with the same result as the time before, it worked for a few hours, installed windows updates, then crashed on the 3rd or 4th time turning it on. I decided next to try reinstalling and then going online to see if there were any updates for the BIOS or drivers on the Motherboard, but now I can't get it to even bring up the boot menu, so now I'm just left wondering was it the motherboard, or is it the CPU, or the RAM? The problem was strangely intermittent so I thought it had to be a software issue, since a hardware issue would ALWAYS fail to boot, right? But now it seems to be a hardware issue, because it's not bringing up anything. Any suggestions?

• WIN7 constant BSOD 0x7B on boot, not producing any dump files where to go from here?

  - by prayingpantis

  So my one win 7 pc has been getting a BSOD on boot (roughly a sec after load screen starts) after a power failure. The complete stop code is 0x0000007B (0x80786B58, 0xC0000034,0x00000000,0x00000000) I've searched for quite a while now on the net and it seems like most people gave up after gettting 0x7B and no dump files. What I've tried so far: startup repair - reports it cannot repair computer automatically. BadPatch is reported somewhere in a problem signature contained in the problem details. startup repair with a WIN 7 CD - also fails, I can't recall what the error was, but it was not the same as the error produced with the start up tool shipped with the version of WIN 7 installed on my machine (I think the text had something ACL-ish contained in it) used a boot disk (Hiren's boot iso) - I used it to enable the CrashDump registry key and then after BSOD, read the HDD's dump locations but it was empty. Note, I'm quite sure the registry keys I edited are the correct ones, since the reboot on BSOD option was enabled by default and after I changed the regkey controlling this functionalitty to 0 the BSOD stayed after I booted again. check disk - works and returns no problems, also it seems I'm able to access all my files on the HDD. mem test - works and returns no errors So I'm not sure what else I can do to figure out what is the problem here. I read somewhere that you can use WINDBG to remote debug another PC, but I'm not sure if this is possible since the OS isn't even loaded yet? Also the last driver change I made on the system was installing a video driver, but I had no problems with it and were able to reboot several times until the power outage happened and the BSOD appeared. Any help or guidance for a way to DEBUG this problem would really be appreciated (I'm not really that keen to try a whole bunch of random fixes, I'd rather try and narrow down the problem first).

• Can't access YouTube

  - by Agentleader1

  I can not seem to connect to YouTube at all. If I connect directly to YouTube (youtube.com) I get this: And if I try to connect via video directly (youtube.com/watch?v=), I get this: Here's how this isn't a web issue: I have malware on my computer I believe. And the question here is, how do I get rid of it, or what possible issue could this be? I can verify this is not a website issue or wifi issue, I've tried to connect on another computer in my wifi, and it worked. It is the local machine issue. I've tried to get rid of malware at my best and also have tried to disable possible virus extensions. All can out as the same result: no help. Also, I am unable to find these hiding viruses. I used malware-bytes and Microsoft Security Essentials. Edit: This is OBVIOUSLY Windows.

• 3 Monitor PCI-e Graphics card on Linux (without tremendous pain)?

  - by N Rahl

  As we are all painfully aware, the only way to get multiple monitors AND compositing (Compiz) on Linux is to use a single graphics card that can drive both (or in my case all three) screens. I bought a Radeon 5750 specifically because it claims to able to drive 3 monitors. I can plug in 3 monitors (2 DVI, 1 HDMI) and the Catalyst Control Center shows all 3, but only 2 can be enabled at a time. The exact message is: The current settings cannot be applied. Possible issues may include: - Display(s) cannot be enabled. - Setting(s) cannot be applied due to insufficient video memory. So I'm going to assume that either the 5750 doesn't support 3 monitors, OR, more likely, ATI couldn't be bothered to add that support to their Linux drivers. So this is a multipart question: First, can anyone suggest a PCI Express Graphics card that can run 3 screens on linux without tremendous pain? I'm looking for something where you install the driver and all three screens "just work". Does such a card exist? Second, if you have a 5750, have you been able to get it to do 3 monitors? I'm running Ubuntu 10.04 at the moment.

• Microphone doesn't work

  - by mandy

  I'm having a trouble with my built in microphone. Even if I use headphone with mic, it doesn't really work. The weird thing is, if I clap the green lines of the speaker icon jumps, but if I speak it doesn't. I have also tried some recordings, but I can not hear myself and adjusting the volume didn't help at all. I tried to restore it, still no change. I have updated it in the device manager, but it said there that it's up to date and the devices are working properly. Until I decided to recover the whole system (wherein I pressed zero and switch on button) to my surprise, the settings became different, most programs were deleted, even my files. It's like it was formatted and I'm so sad that the mic was not fixed. I really don't know what to do now. My laptop model is Toshiba satellite m840. I want to it return to its settings/set up just before I Recover the system and bring back all the programs that we're installed and of course, most of all, to fix my microphone so I can use Skype again and other video calling application.. I hope someone could help me. Thanks a lot!

• Why is my computer randomly restarting? How can I fix it?

  - by kinglime

  I have a custom built desktop computer that I've been using since about a year ago. The main specs are: ASUS P8Z68-V LE Motherboard Intel Core i7 2600k Corsair Vengeance 16GB Ram ASUS ENGTX570 GPU Corsair TX650M PSU I was running an overclock of 4.4ghz for my cpu (I have a Hyper212 EVO) and 1600mhz for my RAM but have it currently turned off due to my issues. I am also currently running Windows 8 but this problem occured in Windows 7 too. Basically my issue is that seemingly randomly, with no pattern my PC will reset itself and ASUS Anti-Surge will alert me that something went wrong. This issue is not related to system stress. I can run it fine for an hour maxxed out on Prime95 then later I can be watching a mere YouTube video when it will randomly reset. This has been occurring probably for the last two weeks and it seems to be getting worse. I believe this might be related to the power supply but when I monitor it in the bios and in Windows it appears to be putting out the proper voltages. Also possibly related or not but my Nvidia drivers frequently temporarily fail and then warn me of some kind of kernel error? If I have to buy a new power supply that is what I'll do but I want to make damn sure that's the only issue at hand. Thank you everyone in advance, please help me diagnose the issue and tell me what I can do to fix it. If you need any additional info about my setup please ask me.

• Network bandwidth usage dashboard?

  - by SkippyFlipjack

  I have a couple of wifi access points hooked up to my home network, one of which I keep unsecured for some development I do; there are only a couple other homes within range and they've got their own wifi so it's not a big concern. I also have a Sonos system, Tivo, Roku, a couple laptops, a couple phones, an iPad and a desktop machine, all of which are internet-smart. So when my internet bandwidth tanks and it takes five minutes to load a YouTube video, I want to know what's going on, and there are many potential culprits. I'd like to be able to plug my MacBook into the primary router and see a nice little dashboard of the units on the network and what kind of bandwidth each is using at that moment. I could figure this out from WireShark or tcpdump but figure there has to be an easier way. I've tried a few different commercial products but none really presented the right info. Suggestions? (This may be a question for superuser since my Apple Time Capsule's SNMP capabilities are limited, but I figure admins of small business networks would have dealt w/ the same issue..)

• Seagate 3TB hard drive loses format information

  - by Victor Bugarin

  I have a Windows 7x64 Ultimate, 6 GB memory, 1 TB HD. 3TB Barracuda XT HDD. The HDD is installed on a StarTech 4 bays external enclosure I had troubles so I converted to a GPT, created 1 partition and formatted as NTFS. The hard drive I can write and read to and from the hard drive but it will become unreadable at some point while I am copying files or after I have copied files to it. I have copied large Bluray movies and diverse video files, I have also copied 32 GB of pictures, and I have copied about 86 thousand music files in different formats. At some point the partition becomes unreadable and I have to format the partition again (all files lost) and I have to start the whole process again. At some point I have been unable to copy large ISO (Bluray movies) file images. I have partitioned the HDD in 2 partitions P1 - 2TB, P2 - 1TB and I have lost every single file in either partition the same way. I reformat the HDD and it seems fine. I have run seatools to check the hard drive and it reports to be OK. What gives?

• Windows 8 install from USB freezes

  - by Rafael Almeida

  I'm trying to install Windows 8 from an 8GB Kingston Data Traveler. I'm currently using the Windows 7 USB DVD Download Tool to put the iso into the flash drive. It copies the files, but in the end it says it 'had a problem with bootsect' and could not make the flash drive bootable. This seems to be because my current system is Windows 7 32bits, and the bootsect.exe in the ISO is a 64-bit executable. Then I downloaded the 32-bit bootsect.exe and made the drive bootable by running: bootsect /nt60 E: /mbr Then I restarted and managed to boot via the flash drive, but now everything is very slow. It takes about two minutes for the initial black screen with the Windows logo and the spinner go away, then it goes to a purple-ish blank screen that stays on for about five more minutes and then it finally shows a dialog asking for the installation, date/time and keyboard languages. I input then, click "Install Now" and it takes about three more minutes with a "Setup is starting" screen. After that, the PC apparently reboots, the CPU fan speeds up considerably, and there's no video and nothing more happens even after more than ten minutes. What is happening? I already tried using another USB port and even installing from a Samsung G3 Station 2TB external hard disk, but the same thing happens. The file transfer speed to the Kingston drive was about only 3 megabytes per second.

• Fedora 19 no longer bootable

  - by Parisa

  I had fedora dual-booted with windows on my laptop for a while but with windows refresh grub was gone and my system directly booted windows. I booted fedora with my systems boot options and with this tutorial: https://fedoraproject.org/wiki/GRUB_2 I reinstalled grub2 but then had my system booted into an empty grub prompt: grub So I found the drive containing vmlinuz and initramfs (completely sure about thair location and versions) and tried to manually boot it but after the boot command it said: no suitable video mode found booting in blind mode and nothing happened. Such a tragedy... I have already tried to use live disks rescue system. Funny but troubleshooting options don't apear on my laptop while they do on my desktop pc. I cant even go to boot prompt on my lenovo idepad z400 laptop. I also tried EasyBCD so maybe I could boot it with windows but it comes up with this error: missing AutoNeoGrub().mbr Now I have removed the grub prompt (don't know why) and its really hard for me to reinstall my dearly customized fedora. If anyone knows a way to help boot it again or reinstall it keeping my files and installations I really need it. Thanks PS:I have already tried Boot-repair Disk but it asks me to enable the repo containing grub-efi on my fedora to reinstall the grub2 and fix the boot for me (how could i?).

• Scaling a LAMP website hosted on EC2

  - by Gublooo

  Hello, I'm very new to all this - I've recently managed to launch my website on EC2. As next step, I want to learn how to scale the website. I have a general idea but wanted some input from the experts about how to go about it. My website is based on LAMP but also has Red5 server which allows users to record messages and also used for playing them back. Currently this is the architecture I'm planning to setup for initial scaling. Deploy four small EC2 instances for the following purposes: Instance-1: On this instance I will run the MySql database Instance-2: On this instance I will run the red5 server Instance-3 & Instance-4 These 2 instances will be used to deploy the website and will have Apache running on them. They will communicate with the mysql server on Instance-1 and red5 server on Instance-2 using the internal IP address. As an when required, I will launch another instance of the same EBS - I will have EBS of say 50 GIG where all the mysql data will be stored. Also red5 will use this EBS to store the video messages Load-Balancer - Use the load balancer provided by Amazon to load balance Instance-3 and Instance-4 This is what I have in mind. I could be way off so please bear with me. Also I have not taken into account the case of scaling MySql server as I currently have no idea about how that will be done and whether or not it is necessary initially. I am aware that Amazon provides auto scaling and mysql scaling as well but I dont want to get into that right now. Your feedback is appreciated Thanks

• Is 1GB + 1GB RAM better than 2GB +0.5GB?

  My laptop has two slots for RAM, and currently has two 512 MB chips, for 1 GB. Windows XP is running terribly slow on it, so I want to upgrade the RAM. I could buy two 1 GB chips to replace both of the current 512 MB chips, to give me 2 GB of RAM. Or, the price is the same to buy one 2 GB chip, to replace just one of the 512 MB chips, and give me 2.5 GB total. The RAM it takes is PC2-4200 533MHz DDR2. What do you think would be better: buying two 1 GB chips so it can take advantage of dual-channel operation, or buying one 2 GB chip to end up with more total RAM but not dual-channel operation? Like I said, price is the same, so performance is the only consideration. I'm not doing anything especially intensive like video or photo editing -- just having multiple Office programs open, playing music, browsers, etc., but currently even opening the first application takes forever. If it matters, the laptop is a Toshiba Qosmio G25-AV513 running Windows XP Media Center SP3. Thanks! Kevin

• Games on windows 8 in bootcamp lag even on lowest graphics

  - by Jackson Gariety

  I've been playing Crysis 2 and Skyrim on my Retina MacBookPro (10,1) for months now. The two games used to run super smoothly even on nearly maxed out settings. This laptop has an Nvidia GeForce GT 650M graphics card inside, it runs great. But I recently replaced my Windows 8 consumer preview with the retail copy, and since then, 3D games lag in this odd way, no matter what the graphics settings. Every second Skyrim and Crysis alternates between running smoothly and lagging. It's a cyclical lag that comes and goes like clockwork. I can turn the graphics down to 800x600 with no antialiasing and low texture quality, and it runs much smoother on the "up" motion of the cycle, but every second it moves back into this lag spike. I've tried installing beta graphics drivers, re installing the operating system, re installing the bootcamp support software, and freeing up space (I have about 20 GB free). I can't figure out what suddenly caused this other than some obscure difference between the consumer preview and the retail version. What can I try? Is my video card failing? Are there some other drivers I can install? This isn't normal lag from maxing out the card, it

• How can I take browser screenshots at a higher resolution than my browser supports?

  - by user53575

  I need to take a screenshot of a website as it would appear on a very high resolution monitor... say 16000x12800 pixels. My laptop's screen has a native resolution of 1280x800. Basically, I need to simulate having a monitor resolution much higher than my monitor and video card actually supports. I want the screenshot of the site to look pretty much how it does when you hit CTRL MINUS (zoom out) in Firefox repeatedly, but without any loss of pixels due to scaling. How can I do this? Is there some way to use virtual machine software to simulate a super-high-res display? If not, is there some way to open a browser window bigger than the screen, and then capture its contents as a PNG somehow? Anything else that might work? Here was an answer: http://superuser.com/questions/120266/how-can-i-take-browser-screenshots-at-a-higher-resolution-than-my-browser-support But it doesn't work. Firefox remains in the resolution of the physical screen. The window blinks and shrinks back to normal resolution. Please Help!!
