• Good, secure video chat program

  - by wag2639

  I'm looking for something similar to skype but basically just for me to video chat with my girlfriend. Skype has been kind of buggy lately with its recent iterations and doesn't seem to be progressing as much as when it was with its previous backers. Are there any good, secure video chat programs? Something that customizable and lets you choose framerate vs pixelation and is generally secure (I don't care if the NSA can tap it but no one else, especially over unencrypted wifi's). Open source is preferred but not required. Free or really really cheap is practically required. Also, since this is point to point, an i am a power user (and my gf as well), it can involve some manual setup to establish a point-to-point link. Any suggestions, Thanks.

• Sudden restart when Ubuntu almost loaded from disc.

  - by Wesley

  Hi all, Here are the specs beforehand: ECS K7SEM motherboard AMD Duron 900MHz 2x 256MB PC133 SDRAM The Best Power MT-500P 500W PSU Integrated graphics No hard drive DVD-ROM - will update with brand & model Now, I was starting up this machine after it was left outside for 3 months in winter weather. (I got this from a friend.) I was able to get it started and tried to load Ubuntu from the DVD-ROM. It was fairly successful and got up to the point when the Ubuntu logo is glowing. However, when Ubuntu was about to go to the main screen, the computer crashed and automatically rebooted. Is there any reason why this is happening? Also, I should mention that when I try to hit Delete on the BIOS screen to go to Setup, it only shows a screen with four lines saying something Novell something... I will edit with exact lines. Should I be resetting the BIOS or something? Thanks in advance.

• Raspberry Pi stuck at splash screen

  - by Matthew

  I have a raspberry pi and I am stuck at the splash screen. In the top right of the screen there is an image of a Raspberry. When I first power on the device, I get the colored screen, and then I get the image of the raspberry followed by a white cursor which quickly freezes or disappears. I put on the debian version of wheezy that allows java. (the soft float version) Any assistance would be greatly appreciated. BTW I did have it working at one point in time and all I did was go to the terminal (logged out of the GUI) and did a shutdown -h now command. But since then I've even started with a brand new version of the image and it is still not working. Oh and I did try the same SD card with a version of arch linux and it worked fine.

• Can USB Hubs affect peripheral performance?

  - by Daniel Rasmussen

  Like many laptops, mine has 2 USB 2.0 ports. I'm looking to purchase a USB hub for my peripheral devices. I'm also planning on purchasing a laptop cooler with two USB powered fans, which connects to a USB port but can extend the plug, so it doesn't use one up. (Sorry for the poor description; see the link for a picture.) My questions are these: Can one plug 'too many' peripherals into a USB port? Can I plug my fans into a port, then the hub into the fans, then my keyboard and mouse, mic, and webcam into the extender..? Is it possible to draw too much power from a port? Secondly, will a USB hub affect the performance of any of my devices? I'm mostly worried about my mouse and keyboard. I like wired mice because I've noticed some lag in my Bluetooth mouse.

• Forgot to unmount/eject external hard drive, lost moved files. Mac OS X

  - by balupton

  So I was using my Mac with my external hard drive connected via USB. I moved about 10 GB of data to it (via drag and drop while holding down the Command key to move the files rather than to copy them). They moved to the drive all right, but as I was having some issues and the Finder crashed after the transfer, I was unable to eject the volume and later everything froze so I had to do a hard restart (hold the power button). When I remounted the volume (plugged the external hard drive back in) it no longer had any of the files which I moved onto it. As it was a lot of data, how can I recover these files?

• Linux WD30EZRX WD Green HDD & Blacx Duet 5G Usb

  - by Adam

  I have connected up an WD30EZRX WD Green HDD to a Thermaltake Blacx Duet 5G USB dock in Ubuntu 12.04. Every thing seems fine except when the HDD idles it seems to have error ls: reading directory .: Input/output error after a while and is only fixed by unmounting and remounting the drive as root. I have the following line in /etc/fstab UUID=AAF670E9F670B6E3 /media/3TB ntfs defaults,user,auto 0 0 I have noticed that it seems to go between /dev/sdc2 and /dev/sdd2 devices on remount. I did copy 1TB last night without issue in 1 sitting. But after x mins of idle it has remount issue. Any tips/suggestions on how to proceed would be appreciated. Spent most of the night googling and all its done is made me sad. Edit (tried as suggested): root@mediaserver:/media/3TB# sudo hdparm -B 255 -S 253 /dev/sdd2 /dev/sdd2: setting Advanced Power Management level to disabled HDIO_DRIVE_CMD failed: Input/output error setting standby to 253 (vendor-specific) APM_level = not supported Seems as if that didn't help with this particular drive.

• Computer not displaying anything

  - by Justen

  The computer in question worked last week. It's brand new, never been connected to the internet, up-to-date parts, etc. Last week, I installed some 3D software on it, then shut it down and waited for the license files that arrived this week. I've done this to 4 other PCs with the same hardware and software. I've tried: Hooking it up to 3 different monitors using different video cables 2 other graphics cards and a handful of other things like switching which port it's plugged into before and after a restart. I have the driver disc, and a windows reinstallation disc, but they won't do me any good because no display at all for any interval of time. All the fans are moving: psu, gfx, cpu etc, so I don't believe it's a power issue. Here are the specs I know of: 4GB RAM 8800 GTX 700w PSU Intel dual core (not sure of model) Anyways, I'm open to ideas.

• How to make the start menu find a program based on a custom keyword?

  - by Pierre-Alain Vigeant

  I am searching for a way to type a keyword in the start menu Search programs and files field and that it will return the application that match the keyword. An example will better explain this: Suppose that I want to start the powershell. Currently what I can type in the search field is power and the first item that appear is the 64bits powershell shortcut. Now suppose that I'd like ps to return powershell as the first item of the search list. Currently, typing ps return all files with the .ps extension, along with a control panel options about recording steps but not the powershell executable itself. How can I do that?

• Can a Double-Density Floppy drive be swapped out for a High-Density drive?

  - by Ben

  I'm trying to fix the floppy drive in my Roland MC-500. The floppy drive inside is a Matsushita DDF3-1 which doesn't seem to be in production anymore. The DDF3-2 is still available, however it is an HD drive. Does anyone know off the top of their heads if there is any issue with simply swapping the two drives? Could the power usage be different on the drives? Since the machine is expecting a 720k DD drive, are there any jumper settings to have the HD drive function as a DD drive?

• Click sound from computer when shut down

  - by user32569

  Hi, I build my new computer yesterday and I noticed, when computer is shut down, I mean the exact time its looses power from PSU, relativelly loud CLICK sound occurs. Please does anyone knows from where? I think MB, SSD, VGA, CPU nor coolers are not cousing this. I would guess maybe Samsung 1TB HDD (maybe when heads go back to LZ) or some hard safety switch or relay in PSU? Or just the MB speaker? (Yes, its actually installed). Do you have any experience with this? Thanks.

• My HP-Vista based laptop has become very slow recently

  - by goldenmean

  My HP laptop which has Vista Home premium. When I try to start Firefox, internet explorer, it becomes very slow. No other app. When i checked the Performance in Task Manager. It shows the Physical memory , Free as 0 bytes, almost always. This has been recently. Earlier it didn't used to be zero. Laptop has 2GB of RAM. I have nothing running in my tray except - Sound control, Laptop power plan indicator,Network status indicator. There are no other processes whose memory usage adds up to so high to make Free memory as 0. Then what could be hogging the memory and make the laptop very slow. Any pointers would help as it is crawling at the moment.

• Windows 7 resizes desktop when I switch of a monitor

  - by Stijn Sanders

  I have a workstation with two monitors and the desktop extended over them. I have a lot of applications open (generally maximized), and I have a personal preference which application is on which monitor (let's say editors on the right, data retrieval and display on the left). I have recently upgraded to a workstation with Windows 7 and when I power off a monitor (typically when going home at the end of the day), the desktop-expand-over-monitors disables and all applications are switched to the main monitor. (Also the taskbar I keep on the left resizes to about one icon's width.) This is highly annoying, since I now spend the first minutes of work each day switching the applications back that were on the monitor on the right. Is there a way to prevent this? (It says no here.) Is there software I could install that can prevent this?

• Hypertransport sync flood error

  - by Carl B

  What is it? And what causes it? Is it only for uncorrectable DIMM Errors(Troubleshooting DIMM errors)? When an UCE occurs, the memory controller causes an immediate reboot of the system. During reboot, the BIOS checks the Machine Check registers and determines that the previous reboot was due to an UCE, then reports this in POST after the memtest stage: A Hypertransport Sync Flood occurred on last boot 3 BIOS reports this event in the service processor’s system event log (SEL) as shown in the sample IPMItool output There are what seems to be some suggested answers to include Bad Caps Bios verisons (happens in one version not the other) Graphics card issues Lack of power to the CPU The list of possible generators seems to target everything but the computer case.

• Logging in to a locked computer

  - by Cpt. Jack

  Just recently I have stumbled across an old family laptop that has been out of use for nearly two years. The OS is Windows Vista Home Premium so I'm not quite as enthused about my find as I originally thought I was going to be. However, when I power up the computer it immediately bring me to a login prompt. No one in the family remembers the password it is set to and I am eager to get into this machine. Does anyone know of a way to work around this issue and get into the computer to be able to find out what was configured and saved on it two years ago. Without re-installing the OS I want to bring it back into commission within the family.

• Dell Inspiron/Windows Vista sleep/hibernate issue

  - by sarge

  When I hit the sleep button in Windows the computer looks like it's going into Sleep mode but a few seconds later it's restarted, and stops with this error message: internal hard disk drive not found To resolve this issue, try to reseat the drive. No bootable devices--strike F1 to retry boot, F2 for setup utility Press F5 to run onboard diagnostics. The computer is running Windows Vista (SP2) and I have installed all available Windows Updates and the latest manufacturer drivers. I have already tried to reseated the drive, ran the onboard diagnostics and there were no errors. I have changed the power settings for all devices where it's available so that they are not allowed to wake up the computer. Any ideas?

• rundll32.exe constantly running taking up resources slowing down my Win 7 computer

  - by Joe Fletcher

  Over the past week, my Windows 7 Home Premium computer (8gb RAM, 64bit) has been running slowly. When I look at my processes, there are always 2 rundll32.exe's running taking up 3 & 25% CPU power, memory slowly creeping upwards from around 115mb to 160mb each in the time it has taken me to right this message, sometimes popping upt o 300mb and back down. Svchost.exe is at 260mb. When I end those processes, everything returns to snappiness. I recently did some Windows Updates, and I think it was around the time my computer started acting slowly, but I can't remember if it was before or after the updates that things started running slowly. Last night I ccleaned & defrag'ed. How can I diagnose what's causing the slowness?

• Radeon hd 6570 black screen

  - by Sho

  I got some problem with new graphic card. Every time I use AMD Catalyst drivers on Windows or Linux, screen repeatedly goes black. This usually shows u when i open new cards in a browser, resize a window or run a program. Card runs smoothly on basic drivers but this means low resolution. 1940x1080 is native for my monitor so it causes a lot of problems. I've got a 600W Deus G1, so the power is not the problem. Maybe its a silly question, but would going form a vga cable to hdmi help to improve this situation? If not, can it be caused by slow processor or old mainboard? Im getting kinda confused about this whole thing...

• How do I make webmin secure?

  - by Josiah

  I want to install webmin to make server administration tasks on my Ubuntu 10.4 server easier. However I'm very nervious about having that kind of power accessable over the web. So I want to know how to secure webmin so that it can't be used to comprimise my server. So far here are my ideas, but I still don't feel comfortable: Make webmin accessable from only the localhost (how?) Use SSH tunneling to access the webmin server whenever I need to administrate it Can anyone help me with instructions on making webmin accessable only from the localhost? What other ways can I make webmin secure?

• Mac keeps switching to second graphics card

  - by 1.21 gigawatts

  I have a MacBook Pro and whenever I enter certain apps (video camera app or Photoshop for example, the graphics card switched. I didn't know this was going on at first; just that the screen kept changing colors as I opened or closed different software. Later someone told me that the software was causing the OSX to switch graphics cards. It's annoying. How do I keep one graphics card (the better one) enabled all the time? I don't care about power consumption because it is plugged in all the time (though I'm curious how much difference it makes). I just want one graphics card enabled.

• How to host a scalable social networking app

  - by christopher-mccann

  I am in the middle of developing a social networking application for a very select user niche which could scale to a few million users. Right now I have always hosted applications on RackSpace Cloud and I have no issues with them at all - always been a really good service and never had any downtime. My question is though does anyone think that cloud computing is not the way to host scalable web apps? Or can anyone with experience of this recommend a better solution. I have always shunned trying to run big servers from my own facilities as I think it seems silly to go to the expense of bringing in big alternative power supplies and all the other necessary precautions when other companies already do this. I looked at managed hosting services but this proved to be a bit too expensive for us at the start and the scalability of it wasnt good enough - it would take a day or two to get a new server provisioned. Therefore I ended up on a cloud platform. If anyone has any recommendations or advice it would be greatly appreciated.

• SQL Server Agents jobs and turning off the server

  - by Tim Joseph

  I'm really new to SQL Agent jobs, but I am attempting to build up a maintainance regime for a server that will be turned off and on again at unknown intervals. It may run without being shutdown for a month, or it might only be turned on 9-5... we don't know and the client can't tell us because they don't know. So what I'm wondering is, what do I need to do to get SQL Server to run monthly and daily jobs either when they are due, or if the due date is missed, get them to be run when the server is next powered on. I could come up with a mish-mash of periodic jobs and 'on-power-up' jobs, but if there is something more elegant that would be wonderful. Obviously I'll need to ensure the SQL Server Agent is configure to start when the computer is powered up, but what else?

• is a mini PCIe SSD worth it?

  - by Narcolapser

  Question: Is getting a mini-PCIe worth investing in? Info: I have a an Acer Aspire 1 n270. It has this mini PCIe slot that is just sitting there empty. I would like to change this, and I would like to speed up my boot time. So I've been considering getting a mini-PCIe SSD. They are about the same price as faster same size drives of the 2.5" variation. The advantage of the mini-PCIe card is that I can have my HDD still. So I have good boot time, but still have the storage of my HDD. What I want to know is: will this allow me to spin down the HDD more often allowing me to save power? Will the OS (Ubuntu 10.04 LTS) see them as separate drives? Is there anything that the mini-PCIe slot could be better used for? Thanks. ~n

• What is the method to reset the Planar 1910m monitor?

  - by Richard J Foster

  My monitor (a Planar, apparently model number PL1910M) is not working. (It is flashing a green / orange sequence which I believe to be an error code. The sequence, in case it helps consists of orange and green three times quickly followed by a longer orange, then another green followed by a long period where both colors appear to be present). I vaguely recall a co-worker suffering from a similar problem, and our IT department "resetting" the monitor by holding down a certain set of keys as they apply power. Unfortunately, I do not remember what that key sequence was, our IT department is not responding, and the Planar web site is blocked by the content filtering firewall we have in place! What is the sequence to perform the reset? (For bonus geek-credit, what does the code mean... as if it indicates a blown component clearly a reset will not help me. ;-))
