• Changing IP every sec with Firefox

  - by Carol

  I looking for ip changer what is faster than PROXY (i tried Elite Proxy Switcher + Firefox add-on, but it's too slow. I set automatic switching to 4 sec and yes he change the ip every 4 sec however it's not enough because it loads pages very slowly.) Secondly I tried the TOR Project but this is not good..because the TOR would be nice and working good however he needs more than 10 seconds, a new identity and it's not to good for me because i want to change my ip lass than 10 sec. So I find the solution. This is IPfucker alias ipFlood (https://addons.mozilla.org/en-us/firefox.../ipflood/) But it does not work on all sites unfortunately...because this is just simulation "Simulate the use of a series of proxy changing at each new connection.". Anyone knows a solution to the problem? Is there an alternative (VPS, Proxy, TOR)? Thanks in advice.

• Internet very slow when upgrading to Ubuntu 9.10

  - by roojoo

  I was running Ubuntu 8.x on my desktop and everything worked fine. Im using wired internet and it worked perfectly, pages loaded pretty fast. However, when I decided to upgrade to 9.10 the upgrade failed at some point, however I was left with what appeared to be Ubuntu 9.10. Since then the internet has been weird. When I go to a website it takes at least 10 seconds for the page to display, however if Im on a site and navigate to other pages on the website it loads quickly. This never happened prior to the upgrade. I thought this may be due to the upgrade not installing correctly so I did a fresh install of Xubuntu 9.10 but the problems are still the same. Im writing this on a Vista machine over the wireless network and internet is fine. Does anyone have any ideas of the issue? Thanks.

• Recommended RAM and disc space for Oracle 11g on Windows

  - by Álvaro G. Vicario

  I need to provide the recommended amount of RAM and disc space (divided in two partitions) so the customer can create an appropriate virtual machine to run Oracle. All I could find in the documentation was a brief listing with minimum RAM and typical/advanced install types. The virtual machine will run latest Oracle Standard Edition One (11g release 2 so far) under Windows Server 2008 x64 and will host a reasonably low traffic web application. How much RAM and disc must I ask for in order to be safe? (Feel free to ask for further details if I've omitted something relevant.) Update: Rough estimations: Database size: 10 MB after installation Growth rate: +3MB per day on average Size of database 'active' data: (not sure of what this means, there's not actual archive so I guess all data is current) Amount of data written per second in peak hours: a few KB Number of client sessions: 3 or 4 at most Frequency and response size of most heavy requests: some reports make heavy table JOINS that need up to 20 seconds to complete but they won't return more than a few thousand rows with plain text. The app also handles BLOBs (typical size from 50KB to 200KB)

• Database connection timeout

  - by Clinton Bosch

  Hi I have read so many articles on the Internet about this problem but none seem to have a clear solution. Please could someone give me a definite answer as to why I am getting database timeouts. The app is a GWT app that is being hosted on a Tomcat 5.5 server.

• Laptop not charging when connected to mains outlet

  - by Josh

  I've had this laptop for a few weeks now, it's a Sony Vaio. I went to charge it a few days ago and plugged in the power cable, but it's not charging. The battery icon in the Windows taskbar to the bottom right says it's plugged in and charging, but the charge level never goes above 2%. I have checked and I don't have a hcarging switch on the laptop anywhere, so it should be charging. If I unplug the cable, the laptop runs out of power within 30 seconds or so, further fueling my thought that it's a faulty battery. Anyone have any bright ideas? If this doesn't get fixed I'll just ring up Sony and get them to send me a replacement battery or something. Thanks.

• Photoshop CS4 slowing down, need advice to improve speed.

  - by Pennf0lio

  Hi, I just recently experienced problem with my Photoshop, It seem that it is slowing down when I am doing graphics design. Big or small files ( from 20 x 20 inch 300 dpi of resolution to 800x600 72 resolution ) it is really slowing down. Particularly when I am panning to my project It just get stuck for a few seconds then back to normal with slow movement. Can you guess what's wrong? I have an updated antivirus and I don't think virus is causing it. other adobe suite is working fine just my photoshop. I am running in windows 7, using Intel Core2 Duo 2.40 Ghz and has an Installed Ram of 2 GB. My primary scratch disk has 21 Gigabyte left and the secondary has a 13.89 GB. I need a solution urgently. I am planning to reformat my computer just to resolve my problem.

• TIME column in TOP command for mysql

  - by michael

  When I run top on my database server I get that mysqld has been running for 4:00.51 and it continues to go up. I assume this means that one process with mysql has been running this long from other posts on here. Its not set to cumulative mode as best I can tell as the heading looks like it would change to CTIME if that be the case. What I'm wondering is if this is normal for a site that makes a lot of individual connections using PHP. I shouldn't have any long running processes that would hold on to a mysql connection for this long, only seconds at most. Am I incorrect to assume that this time relates to one connection/process running? I think usually I see it flash up and away on the TOP, not just stay there with this number increasing.

• Windows XP waits for usb drive on almost every operation.

  - by Tomasz Kowalczyk

  Hello everyone, I have a problem with my Windows XP operating system, particularly with the USB device that is plugged in - 1TB WD My Book external drive. I haven't found any information about such behaviour when searching in Internet, so I have to ask You. The problem is: when I am using computer, especially during work (programming), when I try to access any information on a hard disk ("internal" one), Windows seems to "consult" it with the external drive. For example, when I open file selection dialog window, if I try to change directory, system activates external drive, reads something (I hear the disk's operational noise) and after some seconds of such pause it makes the operations I requested. There are many situations in which I can reproduce this behavior - opening My Computer, shutting down system, opening partition folder from My Computer - every operation involves the usage of external drive. Please understand me properly - this is not something that happens EVERY time, but at least "many" times a day. What causes such behavior and how can I "turn off" external drive when it's not needed? Thanks in advance for your answers.

• Disable Offline Files (mobsync.exe) on Windows 7 Home

  - by Synetech

  This morning I was watching the CPU graph of a Windows 7 Home laptop and noticed that every few seconds, the CPU would spike several percent. I watched the processes and determined that it was mobsync.exe (Offline Files) that was the culprit. I tried the usual steps that Googling turns up, and clicking the Manage Offline Files link to bring up the Offline Files dialog to click Disable Synch does not work because the dialog will not display. This makes sense since everything I have read indicates that Offline Files is not even included/supported in the Home version, so I am at a loss as to why it is running at all, let alone why it is sucking up CPU cycles. (My best guess is that it was started when they pressed Win+X to access the Mobility Center.) Of course I can just kill mobsync, but it could always just come back. How/why would mobsync be running on a Home version and how can it be disabled (of course the Group Policy editor is not available on a Home version).

• HP Printer odd behaviour in Vista Home Basic

  - by ricardo.acras

  I Have a HP 1018 printer. In my previous PC (with vista home premium) it worked just fine, and still works. In my new PC, which came with vista home basic, the printing almost never works. What happens is as follows 1 - I install the printer, windows says its ok. 2 - I send a document to print. 3 - Printer screen (spool) shows the document for 1 or 2 seconds and then it disappear. For two times it worked after numerous reinstallations, and after I restart my computer it stop working again. Any Ideas?

• Gmail firing background tasks in Chrome and Firefox

  - by Keith Bloom

  I am experiencing a strange problem with Gmail running on Vista and it started when WindowsUpdate last patched my computer. Since then when Gmail is open in either Chrome or Safari the pointer changes to the Working in Background state every couple of seconds. You can imagine how distracting this is. I have never used Gmail in IE before so I loaded it up, Gmail wanted to load the GoogleTalk ActiveX control which I declined. Now Gmail in IE, I'm using version 8, didn't fire these background processes so I'm thinking it has something to do with GoogleTalk. Has anyone experienced this problem? Also does anyone know how to disable GoogleTalk in FireFox of Chrome.

• Firefox being really sluggish on php.net website?

  - by Rory

  Is it just me, or is firefox (3.5 on Ubuntu 9.10 karmic) really sluggish when opening the PHP.net website? When I have several tabs open with just the PHP.net website, and I tab up and down (with Control-PageUp/Down), it's slow to change tab. If I do it quickly, then firefox freezes for a few seconds (I know because it goes grey, which is a compiz feature to show unresponsive windows). The CPU usage also goes up when I'm tabbing to PHP.net pages. UPDATE: This appears to happen for all PHP.net webpages. For other pages, on other sites, Firefox is fine (for me).

• Suppress EXT3-fs warning on mount

  - by STM

  I am familiar with output suppress on Unix machines, ie: cat /file/that/doesnt/exist > /dev/null 2>& However I can't seem to suppress the output of mount when an ext3 filesystem is mounted for the nth time, and it recommends an fsck. As it happens, fscks are run regularly by another machine, so these warning messages are needlessly interrupting the flow of output to my pretty bash script. These are the errors: # mount -t ext3 /dev/sda1 /mnt > /dev/null 2>& kjournald starting. Commit interval 5 seconds EXT3-fs warning: maximal mount count reached, running e2fsck is recommended EXT3 FS 2.4-0.9.19, 19 August 2002 on sd(8,1), internal journal EXT3-fs: mounted filesystem with ordered data mode. Can anyone shed some light on this? I'm clearly blocking both fd's, but somehow output is still getting through. This is GNU Bash v2.05a

• bad ram or bad motherboard

  - by user39508

  I have a computer which crashes after about 5-45 seconds of operation. It can run memtest86+, and it doesn't display any errors, but it doesn't prevent it from crashing within the time frame listed above. The heat sink appears to be installed correctly, and I don't think it is related to overheating. The motherboard is connected to the ram and a monitor, nothing else is installed. The processor is an atom 330, running memtest86+ 4.0. Any insight into if the ram is bad or if it is the motherboard/psu/cpu? Thanks!

• ubuntu server 10 - slow and can't remove desktop environment

  - by Alex

  i'm running ubuntu server 10.10 with the desktop environment. simple page requests are taking over 5 seconds even when connecting to the server through our local network. i believe this is partially related to having the desktop environment installed, as the server worked faster (but not as fast as it should considering that it's on the local network), but tasksel fails every time (aptitude failed 100). my knowledge of networking and linux in general is limited. would really appreciate ideas on how i can troubleshoot this problem. oh also, in the system monitor, one of the processors is almost always around 100%. i doubt this is normal too....

• How can I recover [data from] my failing USB key?

  - by moe37x3

  I have a Corsair Flash Voyager USB key, and it's almost completely failed. When I plug it into my [WinXP] computer, the OS mounts it and open up explorer to the drive's root directory. However, if I try to copy any data off, I get an error message saying that the device is not there. If I leave it plugged in, the OS seems to oscillate between seeing it and not seeing it, since the "Safely Remove Hardware" tray icon appears and disappears every few seconds. The damage was probably caused by my abuse, either from plugging it in with my keys hanging off of it or from losing the cap and keeping it in my pocket uncapped. Is there anything I can do to save the data from it or even rehabilitate the drive?

• Why screen freezes in Windows 7 and Vista?

  - by Hasan Gürsoy

  On Windows 7 and Vista I use auto-hide task bar and turn off graphic card after 1-2 minutes. When I want to use my desktop again screen freezes sometimes for 10 seconds. What I do does not effect anything immediately but cursor moves. For example if I click Firefox bookmark it opens when screen unfreezes. This happens at any of my computers and about a month after new installation. I don't think that problem is related with the drivers.

• How to statically configure DNS servers on a Cisco router when the WAN interface uses DHCP?

  - by Massimo

  I have a Cisco router (model 887VA, IOS 15.4) used to connect a LAN to the Internet via ADSL. The WAN interface uses DHCP: interface ATM0.1 point-to-point ip address dhcp I need the router to use a statically-defined DNS server for name resolution: ip name-server A.B.C.D However, the router insists on using the DNS servers supplied by the ISP via DHCP: Router#ping www.google.com Translating "www.google.com"...domain server (<ISP DNS>) [OK] Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 173.194.116.208, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 44/45/48 ms How can I tell the router to ignore the ISP-supplied DNS servers and only use the statically-configured one?

• Windows Explorer slow response when disconnect from the network

  - by ITGuy24

  As a Systems Admin I have seen this issue repeatedly and it drives me crazy. Basically the problem occurs when you open My Documents or My Computer (Windows Explorer) there is a big delay ranging from 5-25 seconds before it actually opens and shows the content. Sometimes the problem continues with each subfolder you open. The problem is most common when disconnected from the network and when you have mapped drives. The most common solution for this problem is to disconnect any mapped drives or printers that are discconected/not reaachable. I have also heard that turning off "Automatically search for network folders and printers" can solve this issue but I have yet to see this work. Does anyone know of any other work arounds for this?

• Can't access website on local network

  - by Romain

  I have a personal website running on my PC (Ubuntu), connected to the internet through a router. I can connect without any problem to my website when I'm not at home so I guess my router is correctly configured but whem I try to access the site using a local adress at home (192.168.XX.XX), it times out after 30 seconds or so. What tool could I use to find out where is the problem? I have tried a tracert command on my Windows PC but add just a useless line. If it's of any help, my website is running on Tomcat 6 but I don't think the problem is here as it would be weird that the server would be configured to be accessible from the internet but not the local network.

• How to use mencoder to speed up video ?

  - by timday

  There's a webcam streaming WMV video that I can play/record with mplayer/mencoder (Debian Lenny including Debian-multimedia) just fine. I'd like to capture the video such that, when played back, it's faster (so say 100s of real time zooms past in every 1s of video). The "frameskip" filter seems like it ought to do this, but when I try e.g mencoder -o output.avi -ofps 25 -vf framestep=100 -ovc lavc -lavcopts vcodec=mpeg4:... <mms source URL> what I actually get is something which plays for the same length of time as it's allowed to capture for, but which only updates the displayed image every 4 seconds. Is there any way mencoder can be persuaded to do what I want ? (By the way, ideally I'd like to average the frames together to obtain motion-blur instead of just dropping/discarding most of them.).

• Could a too low voltage during long periods damage my computer fan?

  - by Sopalajo de Arrierez

  Computer fans use to run at 12Volt, but most as for today they allow 9Volt or even less to slow down the fan speed (RPM, Revolutions Per Minute). In cases of too low voltage, the fan stops, but I can see it "trying to start again". For example: my Tacens 9dB fan stops at about 10 Volts, but to start it again, 10.5Volt is not enough, and the engine tries to move the fan (I can see a small movement as an "attempt" to move) each 1-5 seconds, but it does not succees, so the fan keeps at 0 RPM. Maybe that "attempt" to move could damage the internal engine of the fan when it last for hours or days?

• Router's ssid changes from infrastructure to ad-hoc

  - by waldo

  For a period of time the router's ssid is shown (on various computers) as a normal infrastructure network - computers connect fine and everything works however after a few minutes / hours all computers see the same ssid as an ad-hoc network (not infrastructure). At this point a computer that was already connected continues to work - a computer that isn't cannot connect. Rebooting the router temporarily restores the visibility of the correct infrastructure ssid. Is something interfering? Connecting computers: macbook (2009), iphone 3g, windows vista desktop, windows xp desktop. Details: - D-Link DSL-2740B router set to WPA2-PSK (Personal) - Enable Wireless : Yes - Wireless Network Name (SSID) : ###### - Country : Australia - Wireless Channel : 1 - 802.11 Mode : Mixed 802.11n, 802.11g and 802.11b - Channel Width : Auto 20/40 MHz - Transmission Rate : Best (automatic) - Hide Wireless Network : No - Group Key Update Interval : 0 (seconds)

• MacBook Pro shutting down instantly after attempt to update firmware

  - by Luke Dennis

  I tried to apply a firmware update on a MacBook Pro 2.4ghz (2008), and after rebooting, the fans kicked up to maximum, the screen lit up, and then it immediately died. Now when I try to boot, it does the same thing: the fans crank to max, the screen lights up, and then it dies after about 2 seconds. Resetting the power manager does nothing. It doesn't stay up long enough to choose another boot drive or boot from CD. I have no idea what else to try. Help?
