• External Display connected to Macbook pro won't sleep

  - by Moiz

  I have Macbook Pro with OSX 10.6.8. It is connected to external display (HP 2311x) using Thunderbolt to HDMI cable. My Macbook display goes to sleep after every 15 minutes of inactivity but the external display won't go to sleep. It does try to go to sleep but wake up immediately. It does that in never ending loop. I have to manually turn off the external display. Is there some settings I need to change to make external display sleep when Macbook display goes to sleep? Any suggestions? Thanks in advance!!

• My Windows 8 computer does not come out of Standby

  - by Jikag

  My computer will not come out out of standby. It has had this issue ever since I bought it ~4 years ago. When I purchased it, It came with Vista, I have since upgraded it to 7 and now 8 Pro, each time hoping that it would fix the problem, each time finding that it did not. My computer is an HP Pavilion Model #: m9500y. The computer goes into standby, but does not come out of it properly. If Hybrid sleep in on, it does not respond at all. If Hybrid sleep is off, It comes out and I can see the desktop for a bit, but then the screen goes black again and I have to reboot. I have tried Running a sfc, and a chkdsk in case it's a corrupted file, but it hasn't helped. This isn't too serious an issue because I can just shutdown my computer and turn it on the old fashioned way, but it is annoying and I would appreciate some advice going forward as I'm currently stumped.

• set up pernament ramdisk in ubuntu to not using ram when is the ramdisk empty

  - by robo

  Hi I've got 8GB RAM on my laptop running Ubuntu 12.04. I added following record to /etc/fstab tmpfs /media/ramdisk tmpfs defaults,noatime,mode=1777 0 0 What exactly it means? I have tested that I can save 4GB to ram disk at most. Why exactly 4GB? Where did the computer get this number from? And what happens when I don't use that ram disk for a while and when the directory /media/ramdisk is empty? Does it mean that my system can use whole 8GB ram? And what happens when the system runs out of ram? Will the most rarely used things be moved to swap? And should I turn of swap if I think my system will never need it? Will turning off the swap make my computer faster? And can I even remove the swap partition? And will the hibernation work correctly then?

• How to prevent hard drive from spinning down Windows 7?

  - by JL.

  I had a Western Digital External 1TB drive, which I was accessing via USB. I decided one day, that I would prefer to mount the HDD in my case, and access it via SATA interface. So I took it apart, and the actual mounting was a breeze. The only thing is, I think the device has some default power saving features, which means the device tends to stop spinning when idle for (x) amount of time. This creates delays when I am accessing the HDD. Is there anyway I can turn off these power saving features for this HDD?

• IIS displaying page differently when localhost is used in URL vs. hostname

  - by maik

  I'm having (yet another) strange problem with IIS. When viewing an ASPX page I've designed on my local machine by browsing to http://localhost/page.aspx the page looks as expected (and looks the same in IE, Firefox and Chrome. If I change localhost to my_hostname the page is rendered with a disabled vertical scroll bar. The behavior was first noticed when I published my site to our live server and saw the same discrepancy. After beating my head against the wall I tried what I described above and was able to duplicate my "problem". So with that, I turn to you guys. This wouldn't really be an issue (save for the cross-browser inconsistency) except that this screws up an "absolute"ly positioned <div> moving it partway off the screen instead of being centered like it should be (and is when viewed any other way except in IE when the address is anything but localhost).

• Is this a graphics card failure?

  - by Alexander Lozada

  I own an older 32-bit Dell XPS 410 that I intended to use for gaming. Currently, I have a ATI Radeon 4000 series card installed, along with a Core 2 Duo and Ubuntu 12.10. I'm fairly certain that my problem is a GPU failure - but before I spend money on a new one, I want to make sure other components aren't the problem/if it would be cheaper just to buy a new PC. Here are my symptoms: Computer power button remains orange (usually green when successfully started.) A fan gets increasingly faster until powered off. Monitor remains black when started, receiving no signal. When powered on, the computer will power itself off near instantly, and then turn on again. If startup is successful, sometimes the screen will become jittered and unusable unless restarted. Is this just a GPU failure, or something more extensive like the motherboard?

• Hardware issue: UI freezes and hard drive light goes solid several times per hour

  - by alchemical

  I have a workstation that has been acting up for the last few weeks. It currently has Windows Server 2008 R2 installed on it, and 2 HDD mirrored. A few times per hour the screen will freeze up, applications will say "not responding", sometimes the screen will turn a lighter shaded color--at the same time the HDD light is on solid. This lasts anywhere from 10 to about 50 seconds. Could this be something with one of the drives or the mechanism keeping the mirror in place? Any other ideas?

• best ftp program (paid - not free)

  - by Victor Kimura

  Just would like some feedback on the best ftp program (not free). The requirements I'm looking for is: - secure ftp - for use on mac, linux, windows - backup utility with scheduler - for use on more than one computer (multi-license) I'm using wsftp from 2007 right now but it's only good for windows. It's license is only good for one computer. And after some vista updates it's making some strange noises. I tried to turn off the noise (via control panel) and it's still making that noise and I turned off the sound within wsftp too. I like the program but I think it's time to look for a new one. Thank you, Victor

• Windows 7 made 2 hour shift for Daylight Savings Time

  - by P a u l

  My win7-64 ultimate has set the clock ahead 2 hours. It appears to have done it in increments of 1 hour, with the second 1 hour shift made sometime today. The first, correct, shift for Daylight Savings was sunday morning. In the clock settings it says Mountain Time UTC-7, but the official time should be Mountain Time UTC-6. Update for Windows 7 (KB979306) IS installed. Microsoft appears to be able to turn even setting the clock into a hairball. I need the clock rock solid since I use the computer to record TV programs.

• Update KB951847 (3.5 SP1 and Family Update) fails on Windows Server 2003 repeatedly

  - by Ducain

  We have a Win2K3 server that is perpetually stuck on the following update: Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update for .NET versions 2.0 through 3.5 (KB951847) x86 It fails every time, and I'm at a loss on what to do about it. WHAT I'VE TRIED: Saw an article that said to turn off the update service, rename C:\Windows\SoftareDistribution\ and then restart the update service. Did this, ran the update, and it failed on this same one. I tried to run the update manually at C:\Windows\SoftwareDistribution\Downloads\Install\ and again it fails. Says, "None of the products that are addressed by this software update are installed on this computer. Click Cancel to exit setup." Because of this issue, none of the previous updates will work either. I will give one large pink-glazed donut with sprinkles to anyone who can help me slay this beast.

• Windows Security Center Service is missing

  - by TheTub

  I am trying to fix a Windows 7 machine here that has been infected with all kinds of Malware. I have removed all of them as far as I can see but I am stumped by one last task. One little bugger managed to remove the Windows Security Center service from the list of Windows services. So I cannot start it or set to automatically start. At the moment I cannot get the Windows firewall to turn on or any anti-virus software. The security center shows the following image when I try: Does anyone know how to add this back to the list of services so I may set it to start. I don't have a backup of the registry for this computer (it's not mine). Many thanks TT

• Recovery of Pinnacle Studio Project Files

  - by seanieb

  My external hard drive had some sort of issue a few months ago, but I was able to recover my files using a data recovery software program. However my Pinnacle studio files are not being recovered as before, they are being recovered as directory's/folders that have sub directory's and files. And I have tried with several different recovery programs and they all recover the projects as directories. And the projects all contain one file called README.TXT: * WARNING This directory contains the descriptive data of the project, split into. various subdirectories and files for better access. DO NOT EDIT, ADD, CHANGE OR MODIFY ANY OF IT'S CONTENTS! This gives me hope that I could some how just turn the directory into a .stu Pinnacle studio project file. How would I go about doing this? Or is there another way to solve this problem?

• Is it possible to mount a hot-swappable drive when it is turned on?

  - by John

  In my PC, I have a hot-swap drive. Usually I keep it off to save power. I only really use it when accessing from another PC on the network. Is it possible to configure /etc/fstab to mount this drive when I turn it on (without having to shake the mouse, open file manager and click the drive to have it mounted? Currently, I have: UUID=a869e5ca-7d3b-4d64-91e2-eadbecd8c9e5 /media/i-TVShows ext4 rw,nosuid,nodev,auto,user,uhelper=udisks 0 0 in my /etc/fstab file but it doesn't seem to do the trick. I want the drive to be user-mountable, on power on, with RW access, and I'm thinking of adding 'nofail'...this is my first time writing to the fstab file, and a lot of the parameters I took from the output of 'mount' so feel free to correct any oddness you find. Thanks

• Run one virtual machine on a Linux server + standard Linux functions

  - by fistameeny

  Hi, I am looking for a method to setup a Linux server (running Ubuntu Server) that uses Samba for file sharing, as well as hosting a Windows virtual machine (in this case, Windows Small Business Server 2003, which in turn hosts SQL Server Express - Exchange won't be used on this). I would like to have the Linux server serving the files over Samba, and hosting the Virtual Machine. This obviously rules ESXi out as it couldn't do Samba at the same time. What would be the next best solution to give reasonable speed? Vmware Server 2.0, VirtualBox, Xen? There will be 10-15 users accessing the Samba shares and the SQL Express virtual machine. Matt

• DPMS, keep screen off when lid shut

  - by Evan Teran

  I have a laptop running linux. In my xorg configuration, I have DPMS setup so that the screen automatically turns off during several events. In addition to that I have to the following script tied to ACPI lid open/close events: #!/bin/sh for i in $(pidof X); do CMD=$(ps --no-heading $i) XAUTH="$(echo $CMD | sed -n 's/.*-auth \(.*\)/\1/p')" DISPLAY="$(echo $CMD | sed -n 's/.* \(:[0-9]\) .*/\1/p')" # turn the display off or back on export XAUTHORITY=$XAUTH /usr/bin/xset -display $DISPLAY dpms force $1 done Basically, this script takes one parameter ("on" or "off") then iterates through all of my running X sessions and either turns on or turns off the monitor. Here's my issue. When I close the lid of the laptop, the screen goes off as expected, but if a mouse event occurs (like if something bumps into the table...) then the screen turns back on even though it is closed (I can see the light through the side of the laptop). Is there a way to prevent the screen from turning on during a mouse event if the lid is closed?

• Thin virtual host

  - by Adam Ryczkowski

  My work setup relies on old Windows XP. Now, when Windows XP isn't supported by new hardware, it's getting harder and harder to buy a notebook on which Windows XP can run natively with all essential hardware (wireless cards, graphics, sound etc). Since I don't expect my personal setup to turn away from Windows XP any time soon, I'm investigating the following trick: why not buy any decent hardware which Linux can fully utilize, and use it as a virtual host for a guest session with e.g. Windows XP. I like using hibernation, so I prefer this Linux to be as thin as possible, only enough to support VirtualBox, KVM or any other virtualization software. Question: Are there any "standard" ways to do this, like Linux distributions aimed specifically on being light virtualization host?

• Find optimal strategy and AI for the game 'Proximity'?

  - by smci

  'Proximity' is a strategy game of territorial domination similar to Othello, Go and Risk. Two players, uses a 10x12 hex grid. Game invented by Brian Cable in 2007. Seems to be a worthy game for discussing a) optimal algorithm then b) how to build an AI. Strategies are going to be probabilistic or heuristic-based, due to the randomness factor, and the insane branching factor (20^120). So it will be kind of hard to compare objectively. A compute time limit of 5s per turn seems reasonable. Game: Flash version here and many copies elsewhere on the web Rules: here Object: to have control of the most armies after all tiles have been placed. Each turn you received a randomly numbered tile (value between 1 and 20 armies) to place on any vacant board space. If this tile is adjacent to any ally tiles, it will strengthen each tile's defenses +1 (up to a max value of 20). If it is adjacent to any enemy tiles, it will take control over them if its number is higher than the number on the enemy tile. Thoughts on strategy: Here are some initial thoughts; setting the computer AI to Expert will probably teach a lot: minimizing your perimeter seems to be a good strategy, to prevent flips and minimize worst-case damage like in Go, leaving holes inside your formation is lethal, only more so with the hex grid because you can lose armies on up to 6 squares in one move low-numbered tiles are a liability, so place them away from your main territory, near the board edges and scattered. You can also use low-numbered tiles to plug holes in your formation, or make small gains along the perimeter which the opponent will not tend to bother attacking. a triangle formation of three pieces is strong since they mutually reinforce, and also reduce the perimeter Each tile can be flipped at most 6 times, i.e. when its neighbor tiles are occupied. Control of a formation can flow back and forth. Sometimes you lose part of a formation and plug any holes to render that part of the board 'dead' and lock in your territory/ prevent further losses. Low-numbered tiles are obvious-but-low-valued liabilities, but high-numbered tiles can be bigger liabilities if they get flipped (which is harder). One lucky play with a 20-army tile can cause a swing of 200 (from +100 to -100 armies). So tile placement will have both offensive and defensive considerations. Comment 1,2,4 seem to resemble a minimax strategy where we minimize the maximum expected possible loss (modified by some probabilistic consideration of the value ß the opponent can get from 1..20 i.e. a structure which can only be flipped by a ß=20 tile is 'nearly impregnable'.) I'm not clear what the implications of comments 3,5,6 are for optimal strategy. Interested in comments from Go, Chess or Othello players. (The sequel ProximityHD for XBox Live, allows 4-player -cooperative or -competitive local multiplayer increases the branching factor since you now have 5 tiles in your hand at any given time, of which you can only play one. Reinforcement of ally tiles is increased to +2 per ally.)

• MySQL replication/connection failing over SSL

  - by Marcel Tjandraatmadja

  I set up two MySQL servers where one is replicating from the other. They both work perfectly, but once I turn on SSL I get the following error: ERROR 2026 (HY000): SSL connection error I get the same error running from command line like so: mysql --ssl=1 --ssl-ca=/etc/mysql/certificates/ca-cert.pem --ssl-cert=/etc/mysql/certificates/client-cert.pem --ssl-key=/etc/mysql/certificates/client-key.pem --user=slave --password=slavepassword --host=master.url.com Both MySQL servers are running on version 5.0.77. There is a difference that MySQL in the master server was compiled under x86_64 while in the slave server under i686. Also both machines are running CentOS 5. Plus I generated certificates as per this page. Any idea for finding a solution?

• Which FLOSS text editor is most like kwrite without being KDE-based?

  - by darenw

  Among text editors on Linux, I usually prefer KWrite. I like that I can quickly turn on/off line numbers and line wrap in the View menu. Other settings are easy to change. Other text editors I've used in the past, such as Gnome's gedit, bury line numbering and wrapping checkboxes deeper into the menu system, making it more distracting to change while concentrating on real work. However, KWrite is a KDE app. On Ubuntu it drags in over a dozen other packages, which I suspect I don't really need. Why would a text editor need all that? It's slower to start up than some other editors I've tried. I'm also trying to run an all-gnome system w/o any KDE, just to see how far I get with it. So, what GUI text editor isn't KDE-based, has few dependencies and quick start-up, easy to change line wrap and numbering, and general similarity to KWrite? What comes closest?

• off-the-shelf HDD in Dell Optiplex 755 - Invalid Replacement - Press F1 when rebooting

  - by Eric Liprandi

  I recently put an SSD into my work Optiplex 755. Since then, every time the system boots or reboots, I get prompted to hit F1 to continue with a message like HDD replacement is not valid. The system works just fine. What I am gathering from Dell's website is that I left the original drive internally as a data drive. And apparently the Optiplex does not support 2 drives in the configuration we purchased originally and complains. Any suggestions on how to get rid of this message? some suggested the MEBx or whatever from Intel and to turn it off, but I did not succeed earlier. It's not a big deal 80% of the time, but I regularly work from home and occasionally need to fire a reboot and well, you don't get the BIOS screen remotely :) Regards, Eric.

• Custom Button in Google Chrome?

  - by Rev

  Is there a way to add a custom button in Google Chrome? I hate all the "Send to Instapaper" extensions in the web store, and love how the bookmarklet works, but I can't stand not having a favicon. Ideally, I'd just add a custom button next to the spanner in the top right, but I can't figure out how to do this. Even installing a custom extension would be fine, so if someone can point me in the right direction for that, that'd be great. Here's the closest thing I've found (it's for Firefox, not Chrome): http://www.readwriteweb.com/archives/how-to-turn-a-bookmarklet-into-a-nice-firefox-button.php

• Using Xbox 360 controller with Mac OS X (specifically turning it off)

  - by Bob King

  So I've been using this driver for a few months with the Xbox 360 Wireless Controller For Windows with my Mac Mini. Here's an article about the driver on Gizmodo. The driver works really well for actually using the controller, but there doesn't seem to be a way to power off the controller without pulling the batteries. Does anyone know of a replacement driver that includes power-off capabilities, or know of some other undocumented way to turn the controller off? Note: I've been having problems getting to the site, but it could be our corporate filtering.

• few questions on making a flash drive to a hard drive

  - by user23950

  I've found a tutorial here on how to trick the operating system to see a flash drive as a hard drive. http://www.getusb.info/usb-hack-turn-a-usb-stick-into-a-hard-drive-or-local-disk/ But I have a few questions: This trick will only work on the os wherein you updated the flash drive driver. Is there a trick that will work like this one, but if you plug in the flash drive to another computer it will still be treated as hard drive? How do I convert it back to a flash drive?

• White Screen of Death

  - by cust0s

  The other night I updated my iTunes to the latest version (through Software Update) when I came to turn on my computer I was greeted with the dreaded white screen of death. I use an early 2008 iMac 24". I've tried the basic things, unplugging/turning off accessories, trying to boot from the install disk, reseting pram, etc, etc. Still no luck and no change what-so-ever. All I've been able to ascertain that my keyboard still works (by ejecting). I should point out that I did recently replace my Hard drive with a Western Digital Black 500GB (though the computer is well out of warrenty) and I'm a little concerned that the problem could be the screen.
