• RAID striping on a desktop machine

  - by Blazemore

  I currently have a 120Gib SSD which is pretty fast for things like game loading times and video editing. However, I was wondering about getting another identical drive and hooking it up with a striping RAID array in hardware (I boot multiple operating systems). This would have the dual benefits of providing a larger logical drive, while also providing greater performance. However, I have a few questions: What kind of performance increase can I expect to see with a pair of good quality SSDs? How expensive is a quality desktop RAID controller? Will the controller present the OS with a single logical drive? Does this mean I can still partition it and multi-boot? Basically, can I treat the RAID controller as "a hard drive" at the OS level?

• One motherboard crashed. Changed and wants to crash again

  - by CoachNono

  My computer started to freeze randomly. I was pretty sure it was the hard drive that was starting to fail. Before I could change it, the motherboard was completely dead. I bought the same one and reinstall it. Everything went working well until my computer started to freeze again and doing the same problem has before. I don't want my motherboard to burn again and I'm really wondering what can be the problem... Could it be the power supply or the video cards that burned the motherboard ? I tested the voltages of the power supply and they seemed fine... The computer worked as is for four years... Here are the specs: ASUS P5N-D Motherboard LGA 775 NVIDIA 750i SLI Intel Q6600 2X EN9600GT 512mb 650w Corsair

• what may cause unexpected log outs?

  - by lalebarde

  Sometimes, my Linux PC unexpectedly closes my session (log out) while I am working, and puts me back the login window. If I have terminal 1 logged with root and 2 logged with another user (without X), these ones are not logged out. For example, for the last three hours, it has happened five times. Other times, it leads to a reboot. So I have investigated: the UPS, but the behaviour is unchanged without it). the temperatures, but everything is fine (cpu, disks, video card). I have started to investigate also: the memory (partially tested - I have to run a full testyt next night). EDIT: totally tested and passed. My configuration is: Linux 2.6.37-tuxonice x86_64 Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz. Any idea please?

• Tiles in Windows 8 are disappearing

  - by BetaRide

  I've just upgraded from Windows XP to Windows 8 on a Dell Latitude D820, which went fine. But, after installing a new driver for the video card, the Start Screen is not working anymore. As soon the mouse touches a tile, they all disappear and I'm left with only the background image. I can go to the desktop by hitting Win+D and if I hit the Win key after some minutes the tiles are there again only to disappear as soon the mousepointer touches them. How do I fix this?

• Computer won't stay powered up

  - by Android

  I have just tried to turn my PC on this morning and it won't stay powered up. It will come on as normal for about 5 seconds, not quite long enough for the monitor to wake up. Then it will power off. After about 2 seconds it will start again, it will continue like this until I pull out the plug. Plugging it in again doesn't restart the cycle although pressing the power button does. I have tried to clear the cmos but beyond that I have no ideas. It was working perfectly when I put it in hibernate last night. NOTE: I am using a Dell Optiplex 755 UPDATE 1: I took out the motherboard battery and it almost came on then it displays the message Error loading Operating System UPDATE 2: After taking out the custom video card, it says "No hard drive present"

• Opening a port to make a connection in Windows 7 [closed]

  - by jannes braet

  Possible Duplicate: trouble with opening a port to make a connection I have watched a video on how to open my ports in Windows 7. I followed the example by going to my "firewall" in "advanced settings" and I made new rules in "inbound rules" and in "outbound rules". I chose to allow connections to all ports, but if I try it with canyouseeme, then it says I can't find the configured port. Maybe it is because the site is wrong, but I don't really believe so. Could someone tell me how I open my ports so that I can connect to them and others to connect to them via the internet (if they have my ip-adress of course)?

• DVD Drive Has Stopped Recognizing Discs

  - by ricree

  My DVD drive no longer recognizes dvds, but does recognize CD-ROMs. When a DVD is in the drive, the computer continues to act as though there is no disc in the drive. However, when a normal CD-ROM is in the drive, it appears to work normally. I have tested on several discs, both video and game, and the behavior is consistent. I have also tested this on both Windows Vista and Ubuntu 9.10, and the issue remains the same. Can anyone recommend a way to fix this?

• RHEL Desktop Recoders... Does they exist? [closed]

  - by Anarko_Bizounours

  Possible Duplicate: Screen capturing application for Linux I've been searching a lot for a desktop recoder on RHEL 6 lately (for tutorial video, about how to use RHEL desktop for non-linux users) But unfortunatly, didn't found anything...

• Best Linux distro for media server on older box

  - by fauxpride

  I have an older machine with these specs: CPU: AMD Athlon X2 @ 2,8 Ghz, 2MB L2 RAM: 4 GB DDR2@ 800 Mhz GPU: Asus 4890 TOP 1 GB I want to turn the machine into a media server via XBMC (so good video and wireless peripherial driver support would also be a plus), but I also want to use it as an OpenVPN server so I can tunnel RDP to my other Windows machine in the network. I mostly want to use a Debian based distro (for the convenience of apt) and right now my options are: Ubuntu, Xubuntu or Mint. Which one do you think is more fitting? Thanks in advance.

• Is \d equal to [0-9] in sed?

  - by user3872279

  7 00:00:30,008 --> 00:00:30,066 by line 8 00:00:31,038 --> 00:00:34,050 or later in the nineteen seventies it was usually a 9 00:00:34,005 --> 00:00:38,634^M video consul but the council was not capable of displaying arbitrate graphics 10 The above lines is in a file named 2.txt. I wanna the lines which doesn't start with number. In practice, sed -i '/^[0-9]+/d' 2.txt works good. However, sed -i '/^\d+/d' 2.txt doesnot. The \d shouldn't be equal to [0-9] in regex?

• Forwarding audio like X in SSH

  - by Akilan

  While it is possible to use X applications remotely by using -X switch in ssh, the sound is being played in remote machine's speaker only. For example if I view a film in VLC/Totem only video is visible and I can't hear the audio. Is there a way to forward audio too? [without digging through Pulse-audio's setup, I mean; Like how ssh understands X forwarding by itself.] I have tried this only in Ubuntu (in various Ubuntu versions from 9.10 through 10.10), if that helps.

• all USB "randomly" disconnect and reconnect

  - by teuneboon

  I'm having a weird issue currently: at seemingly random times(although it seems to happen mostly when USB is used a lot, ie downloading + uploading over my WiFi stick or viewing an HD video from my external hard-drive) all my USB devices disconnect and reconnect after a few seconds. This wouldn't be a HUGE problem if I didn't have to rely on my USB for my internet, because now every time this happens my internet, and with it stuff like remote desktop, crashes. I'm running Windows 8 Pro 64 bit with a Gigabyte 990FXA-D3 motherboard. Now the weird thing: I had the same problem with my previous pc, which had a different motherboard(I think it was an Asus M4A785TD-V EVO). I googled a bit and didn't really find anything about this, only found out I could check if something shows up in the Event Viewer, and I get this error there when the USB crashes: "A timeout occurred while waiting for the EHCI host controller Interrupt on Async Advance Doorbell response." If you require any extra information I'm happy to provide it.

• My laptop (Acer Aspire) doesn't want to start.

  - by Adi87

  I have an Acer Aspire 5520G and recently I had a big problem with it. A couple of days ago I was watching a video on the internet and my laptop froze. I had to shut it down after waiting a couple of minutes and when I wanted to restart it, it acted normally for 2 seconds then it restarts automatically over and over again. I can only shut it down by unplugging it. Nothing appears on screen. I think that it is a hardware problem. If you need further information please leave comment.

• How to copy a folder with many files with integrity check?

  - by RafaelM

  I just got a new hard drive and I want to move many of the folders from the old hard drive to the new one, but I want to make sure everything is copied over correctly. I tried using md5summer to generate md5 sums of the original files, copied files over and then tried to compare md5 sums of both sets of files. This took ages because there are many large video files. Is there any software I can use to make this process as painless as possible? I just need basic file integrity checking. Thanks in advance

• SDL2 sprite batching and texture atlases

  - by jms

  I have been programming a 2D game in C++, using the SDL2 graphics API for rendering. My game concept currently features effects that could result in even tens of thousands of sprites being drawn simultaneously to the screen. I'd like to know what can be done for increasing rendering efficiency if the need arises, preferably using the SDL2 API only. I have previously given a quick look at OpenGL-based 2D rendering, and noticed that SDL2 lacks a command like int SDL_RenderCopyMulti(SDL_Renderer* renderer, SDL_Texture* texture, const SDL_Rect* srcrects, SDL_Rect* dstrects, int count) Which would permit SDL to benefit from two common techniques used for efficient 2D graphics: Texture batching: Sorting sprites by the texture used, and then simultaneously rendering as many sprites that use the same texture as possible, changing only the source area on the texture and the destination area on the render target between sprites. This allows the encapsulation of the whole operation in a single GPU command, reducing the overhead drastically from multiple distinct calls. Texture atlases: Instead of creating one texture for each frame of each animation of each sprite, combining multiple animations and even multiple sprites into a single large texture. This lessens the impact of changing the current texture when switching between sprites, as the correct texture is often ready to be used from the previous draw call. Furthemore the GPU is optimized for handling large textures, in contrast to the many tiny textures typically used for sprites. My question: Would SDL2 still get somewhat faster from any rudimentary sprite sorting or from combining multiple images into one texture thanks to automatic video driver optimizations? If I will encounter performance issues related to 2D rendering in the future, will I be forced to switch to OpenGL for lower level control over the GPU? Edit: Are there any plans to include such functionality in the near future?

• Microsoft launches IE9 preview – No support for XP

  - by samsudeen

  Microsoft launched the developer preview version of Internet Explorer 9 (IE9) at MIX 10 web conference yesterday.This release is aimed getting the feedback from website designers , developers and other community to make IE9 development better from its previous versions. Microsoft will update the developer preview every eight weeks and the next update is expected on mid of march.So what is new and interesting  about IE9 Chakra Chakra (The new scripting engine of IE9) renders the Java script much faster compared to IE8 and other browsers thus improving the performance significantly.According to Microsoft Chakra renders the java script in background with a separate thread parallel to the main engine which is complete new way of rendering from the current browser technologies Standards Microsoft is desperate to make ( surprisingly!!!) IE9 compliance to  web standards by supporting the open standards such as Accelerated support for HTML5 video support for new web technologies such as CSS3 and SVG2. ACID3 Test IE9 scores (55/100) in its latest ACID3 test which is much better compared to the IE8 score (22/100) but not even  nearer to their rivals Chrome, Opera, and Safari which scores 100/100 in ACID3 testing I am little disappointed over not able to download the  developer preview on my XP machine. The early comments looks much positive for IE9.If you want to explore IE9,check the Microsoft Test drive site  at Microsoft IE9 Test-drive You can also download the IE9 developer preview at Download Preview Join us on Facebook to read all our stories right inside your Facebook news feed.

• How to Install Mac OS X Lion on Your HP ProBook (or Compatible Laptop)

  - by Usman

  There’s nothing more satisfying than building a hackintosh, i.e. installing Mac OS X on a non-Apple machine. Although it isn’t as easy as it sounds, but the end result is worth the effort. Building a PC with specific components and installing Mac OS X on it can save you thousands of dollars you might spend on a real Mac. And now, it’s time to step into the portable world. Today we will show how you can turn an HP ProBook (or any compatible Sandy Bridge laptop) into a 95% MacBook Pro! Why should (or shouldn’t) you do it? Let’s clarify whether or not it should be done. Firstly, we all know Apple makes awesome laptops. The design, build quality, and the aesthetics (not to mention, the glowing Apple) would make you crave for one. Secondly, all these Apple laptops are bundled with Mac OS X, which (for some people) is the most user-friendly and annoyance-free operating system. Digital artists, musicians, video editors, they all prefer Mac for a reason. So the verdict is, if hardware design is what you really look for, you should get a real Mac, and we are not at all stopping you from doing so. But if you’re only concerned with the OS (and saving a few bucks in your pocket), you may consider giving this a shot. But remember, it may not perform as good as a real Mac does. The results vary, so hope for the best, and proceed with caution. Why HP ProBook?

• Please guide this self-taught Web Developer.

  - by ChickenPuke

  One of the major regrets in life is that I didn't do something with my introversion. I didn't manage to get past the first year of college because of that. I have chosen the path where there are no video games and other time sinks, all I have is the internet to quench my thirst of learning the ins and outs of the field of Web Developing/Designing. Though currently, I'm taking a Web Design Associate course at one of the best Computer Arts and this is the last month of the class. Even though I'm still a sapling, I love this field so much. So basically, At school I'm learning web design while at home I'm teaching myself web-developing. First thing first, returning to college seems impossible at the moment because of some financial problems. I'm pretty comfortable with CSS and HTML and I'm into PHP/MySQL at the moment. Could you please provide me a web-development Curriculum to follow. And do I need to learn about the theories behind? And I think I'm still young(I'm 18 at the time of writing). Is it a good thing or bad thing for choosing this path? I'm glad with my decision but in all honesty, I'm worrying about my future and employment because I'm an undergrad, coming from a country where companies are degree b!tches, it saddens me so. Thank you. (My questions are the bold parts. )
