• Windows freezes, showing a random color or pattern

  - by Manu

  I have a PC with windows 7, and I'm experiencing random freezes with increasing frequency. After some time (from 30 minutes to a few hours) the screen will shows a random color or pattern (vertical lines) and nothing works anymore, I need to reboot manually. I've checked the events log, but nothing is shown except for the unexpected reboot. I've tested the RAM with Memtest86+ 4.20, and the graphics card with FurMark 1.10.3, no errors have been found. I've updated the graphic drivers and openned the case to remove dust, but the issue is still there. Also, the problem doesn't seem to arise when I'm playing games fullscreen, but when I'm surfing the web, using itunes, or coding. My hardware is as follows : intel core i5 750 CPU, ATI Radeon HD 5670 graphics card, ASUSTeK P7P55D motherboard, two 2Gb KINGSTON DDR3 ram sticks, 2 SATA hard drives, a Netgear dongle for wifi.

• Should I bother upgrading my Opteron 270 Server?

  - by MousePad

  I have an Opteron Server machine (in a large workstation class case) running on the Tyan 2895 motherboard. It's a dual CPU socket board, but I only have one 270 in there. I have 4GB of RAM, but less than 3GB is addressable, even in 64bit mode, due to the way the board is designed. Is it worth spending a few hundred on an additional CPU and maybe some more RAM? The other problem is that one of the two SATA ports on the board had its wire socket break off. So only one drive can be run as of now. I could have it repaired, but at what cost? Add in the fact that the power supply is gunked up with dust and it's a bit of a nightmare. I actually work about it getting too hot. Seems that for the money I could buy a new server rack from Dell, but it also seems a shame to waste an otherwise working, and for my needs still very fast machine.

• How to repair Creative Inspire Speakers 2.1 Volume Control Wheel?

  - by akula

  Due to dust or so, the Volume Control Wheel does not work properly. Volume goes to one speaker, and other gets muted. Vice versa. When I carefully turn the wheel sometimes the Volume works properly or sometimes with noise or muted one side. As I write this, I've cleaned it up with Petrol drops. PCB is drying. I chose Petrol because Contact Cleaner is expensive solution. Am I correct or any other method could be used? Thank you.

• What is the cause of a vertical white line on an LCD monitor?

  - by Deviruchi D Devourer

  This just happened yesterday when I was browsing the internet. My AOC N941Sw monitor is suddenly showing a thin horizontal white line near the center of the screen. The white line distorts the images. I tried checking the cables for loose connection and dust particles but the white line is still here. There are times the entire image below the horizontal white line flickers and move up and down. When this happens, I just turn off the monitor then the flicker goes away but the white horizontal line is still there. After a few minutes, the same thing happen all over again. Is there a way to fix this?

• Computer restarts infinitely after Bios/Motherboard screen

  - by user13176

  Like every morning I turn on my computer (which is kinda new and only couple months old) and I never had any issue with it until now. It starts booting, shows that very first screen which has some motherboard picture and stuff and then it show which buttons to press to enter BIOS and etc. Then it suddenly restarted and after that just kept restarting every 3-5 seconds forever. What could that be? I unplugged power cable, checked all the cables, moved a case, it had some wires stuck under it, blew some dust (but didn't open the case yet) and I tried to boot again and it booted successfully and I am writing this issue now. My specs: i3-3220 3.30Ghz 8GB DDR3 RAM 1TB HDD GeForce GTX 650 Windows 8 x64 I also recently upgraded my security software (that's the most recent thing I did) and it includes ZoneAlarm firewall, Comodo Antivirus and Spybot Search & Destroy. But maybe it doesn't have anything to do with this. Cheers

• The Best Tools for Enhancing and Expanding the Features of the Windows Clipboard

  - by Lori Kaufman

  The Windows clipboard is like a scratch pad used by the operating system and all running applications. When you copy or cut some text or a graphic, it is temporarily stored in the clipboard and then retrieved later when you paste the data. We’ve previously showed you how to store multiple items to the clipboard (using Clipboard Manager) in Windows, how to copy a file path to the clipboard, how to create a shortcut to clear the clipboard, and how to copy a list of files to the clipboard. There are some limitations of the Windows clipboard. Only one item can be stored at a time. Each time you copy something, the current item in the clipboard is replaced. The data on the clipboard also cannot be viewed without pasting it into an application. In addition, the data on the clipboard is cleared when you log out of your Windows session. NOTE: The above image shows the clipboard viewer from Windows XP (clipbrd.exe), which is not available in Windows 7 or Vista. However, you can download the file from deviantART and run it to view the current entry in the clipboard in Windows 7. Here are some additional useful tools that help enhance or expand the features of the Windows clipboard and make it more useful. Can Dust Actually Damage My Computer?

• Introducing Oracle VM VirtualBox

  - by Fat Bloke

  I guess these things always take longer than expected and, while the dust is still not completely settled in all the ex-Sun geographies, it is high time we started looking at some of the great new assets in the Oracle VM portfolio. So let's start with one of the most exciting: Oracle VM VirtualBox. VirtualBox is cross-platform virtualization software, oftentimes called a hypervisor, and it runs on Windows, Linux, Solaris and the Mac. Which means that you download it, you install it on your existing platform, and start creating and running virtual machines alongside your existing applications. For example, on my Mac I can run Oracle Enterprise Linux and Windows 7 alongside my Mac apps like this...(Click to zoom)VirtualBox use has grown phenomenally to the point that at Sun it was the 3rd most popular download behind Java and MySQL. Its success can be attributed to the fact that it doesn't need dedicated hardware, it can be installed on either client or server classes of computers, is very easy to use and is free for personal use. And, as you might expect, VirtualBox has it's own vibrant community too, over at www.virtualbox.org There are hundreds of tutorials out there about how to use VirtualBox to create vm's and install different operating systems ranging from Windows 7 to ChromeOS, and if you don't want to install an operating system yourself, you can download pre-built virtual appliances from community sites such as VirtualBox Images or commercial companies selling subscriptions to whole application stacks, such as JumpBox . In no time you'll be creating and sharing your own vm's using the VirtualBox OVF export and import function. VirtualBox is deceptively powerful. Under the simple GUI lies a formidable engine capable of running heavyweight multi-CPU virtual workloads, exhibiting Enterprise capabilities including a built-in remote display server, an iSCSI initiator for connecting to shared storage, and the ability to teleport running vm's from one host to another. And for solution builders, you should be aware that VirtualBox has a scriptable command line interface and an SDK and rich web service APIs. To get a further feel for what VirtualBox is capable of, check out some of these short movies or simply go download it for yourself.- FB

• Mission 26 Captures Endeavour’s Last Trip in Stop Motion

  - by Jason Fitzpatrick

  On September 21, 2012 the Space Shuttle Endeavour was delivered to the Los Angeles International Airport and spent the next three days being slowly transported 12 miles to the California Science Center. One dedicated team of photographers captured the whole thing. Lead by Matthew Givot, the group followed the shuttle for three straight days, photographing it around the clock. The Endeavor started on Thursday night and went on until Sunday night, with very little sleep to no sleep. The only thing that kept us going was pure love of the art and adrenaline. One thing that stood out the most for me, while I was shooting, was the people of Los Angeles. It was so powerful to see the excitement on peoples faces and the pride of their home town. No matter how many times I would see the Shuttle it would never get old. This has been an amazing experience that I will never forget. My hope is that this film will show you the amount of dedicated people and teamwork that it took to get the Endeavour to its new home. Enjoy. The end result of their labor is the above video, a beautiful time-lapse video of Endeavour’s journey from the airport to its hanger at the California Science Center.

• Curiosity’s Official Self-Portrait

  - by Jason Fitzpatrick

  NASA has released a high-resolution self portrait of Curiosity. The photo, a composite of images snapped by the rover’s agile arm and MAHLI camera, shows Curiosity in front of Mount Sharp. From the NASA release: The mosaic shows the rover at “Rocknest,” the spot in Gale Crater where the mission’s first scoop sampling took place. Four scoop scars can be seen in the regolith in front of the rover. The base of Gale Crater’s 3-mile-high (5-kilometer) sedimentary mountain, Mount Sharp, rises on the right side of the frame. Mountains in the background to the left are the northern wall of Gale Crater. The Martian landscape appears inverted within the round, reflective ChemCam instrument at the top of the rover’s mast. Self-portraits like this one document the state of the rover and allow mission engineers to track changes over time, such as dust accumulation and wheel wear. Due to its location on the end of the robotic arm, only MAHLI (among the rover’s 17 cameras) is able to image some parts of the craft, including the port-side wheels.

• How To Temporarily Disable The Touch Screen In X1 Carbon

  - by Daniel Cazzulino

  I know, why would anyone want to do that? Scott properly predicted: Don't knock a touchscreen until you've used one. Every laptop should (and will) have a touch screen in a year. Mark my words. And surely, less than a year later, the X1 Carbon (an amazing ultrabook for sure) has a touch model. And as of today, the price difference for the touch screen is a ridiculous $30 (actually $24 with a “back to school” coupon right now ;)): So why would you NOT get it? I know for some it works great. Now, let’s get real about touch *for a developer* for a minute. About 99.9% of my time in front of my laptop I’m either using Visual Studio or Chrome. I have my hands on the keyboard ALL THE TIME. I use the trackpoint ALL THE TIME. If I want to scroll, I only have to slightly move my fingers. I don’t click around much on pages: I READ them. So, in a few months of using the X1, I think I touched the screen like 10 times, and it was mostly to clear dust, which drives whatever app is in focus crazy. Plus, at home I have this simple setup:...Read full article

• What You Said: How You Track Your Time

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your favorite time tracking tips, tricks, and tools. Now we’re back to highlight the techniques HTG readers use to keep tabs on their time. While more than one of you expressed confusion over the idea of tracking how you spend all your time, many of you were more than happy to share the reasons for and the methods you use to stay on top of your time expenditures. Scott uses a fluid and flexible project management tool: I use kanbanflow.com, with two boards to manage task prioritisation and backlog. One board called ‘Current Work’ has three columns ‘Do Today’, ‘In Progress’ and ‘Done’. The other is called ‘Backlog’, which splits tasks into priority groups – ‘Distractions (NU+NI)’, ‘Goals (NU+I)’, ‘Interruptions (U+NI)’, ‘Interruptions (U+NI)’ and ‘Critical (U+I)’, where U is Urgent and I is Important (and N is Not). At the end of each day, I move things from my Backlog to my ‘Current Work’ board, with the idea to keep complete Goals before they become Critical. That way I can focus on ‘Current Work’ Do Today so I don’t feel overwhelmed and can plan my day. As priorities change or interruptions pop up, it’s just a matter of moving tasks between boards. I have both tabs open in my browser all day – this is probably good for knowledge workers strapped to their desk, not so good for those in meetings all day. In that case, go with the calendar on your phone. While the above description might make it sound really technical, we took the cloud-based app for a spin and found the interface to be very flexible and easy to use.

• Two Cloudy Observations from Oracle OpenWorld

  - by Gene Eun

  Now that the dust has settled from another amazing Oracle OpenWorld, I wanted to reflect back on a couple of key observations I made during the event. First, it was pretty clear that Cloud was again a big deal at this year's conference. It was hard to not notice that Oracle continues to be "all-in" with respect to cloud computing. Just to give you an idea of the emphasis on Cloud, there were over 300 Cloud-related sessions at this year's OpenWorld. If you caught some of the demo booths in the Oracle Red Lounge, then you saw some of the great platform, application, and social services that are now part of Oracle Cloud, as well as numerous demos of private cloud products that Oracle offers. Second, during Thomas Kurian's keynote presentation on Oracle Cloud, he announced the Preview Availability of a new service called Oracle Developer Cloud Service. This new platform service will provide developers with instant access to environments to better manage the application development lifecycle in the cloud. It provides development project teams access to favorite tools like Hudson, Git, Github, wikis, and tasks to help make innovation faster, more collaborative, and more effective. There's also integration with IDEs like Eclipse, NetBeans, and JDeveloper. If you're a developer, it's an awesome addition to Oracle Cloud's platform services!

• We have moved to larger offices

  - by Chris Houston

  First of all we should probably apologise for the complete lack of blogging over the last 6 months! As web developers we are constantly telling our clients that they should keep their blogs up to date and it seems we have been ignoring our own advice.That being said, we have been very busy moving offices and helping our new host QV Offices setup their new business. As well as all the moving we have not been sitting on our hands, we have built the new site for DairyMaster over in Ireland as well as a separate private website for their global distributor network.As Umbraco Gold Partners we have found more and more that we are working on projects where we are the silent development partners, so although we cannot talk publicly about a lot of the sites we develop, we have some real beauties now in our portfolio :)Now that the dust has settled in our new office ( and has been hovered up! ) we are read for the new year and are looking forward to working on some exciting projects that are currently in the pipeline.We are also intending to run some Hacking sessions for Umbraco as we now have lots of space for developers to come and work with us, so if you have any ideas of a theme for an Umbraco Hackathon then do let us know.And with that it just remains to say Happy Christmas to you all and see you in the new year!

• How can I find unused/unapplied CSS rules in a stylesheet?

  - by liori

  Hello, I've got a huge CSS file and an HTML file. I'd like to find out which rules are not used while displaying a HTML file. Are there tools for this? The CSS file has evolved over few years and from what I know no one has ever removed anything from it--people just wrote new overriding rules again and again. EDIT: It was suggested to use Dust-Me Selectors or Chrome's Web Page Performance tool. But they both work on level of selectors, and not individual rules. I've got lots of cases where a rule inside a selector is always overridden--and this is what I mostly want to get rid of. For example: body { color: white; padding: 10em; } h1 { color: black; } p { color: black; } ... ul { color: black; } All the text in my HTML is inside some wrapper element, so it is never white. body's padding always works, so of course the whole body selector cannot be removed. And I'd like to get rid of such useless rules too. EDIT: And another case of useless rule: when it duplicates existing one without changing anything: a { margin-left: 5px; color: blue; } a:hover { margin-left: 5px; color: red; } I'd happily get rid of the second margin-left... again it seems to me that those tools does not find such things. Thank you,

• AllSparkCube Packs 4,096 LEDs into a Giant Computer Controlled Display

  - by Jason Fitzpatrick

  LED matrix cubes are nothing new, but this 16x16x16 monster towers over the tiny 4x4x4 desktop variety. Check out the video to see it in action. Sound warning: the music starts off very loud and bass-filled; we’d recommend turning down the speakers if you’re watching from your cube. So what compels someone to build a giant LED cube driven by over a dozen Arduino shields? If you’re the employees at Adaptive Computing, you do it to dazzles crowds and show off your organizational skills: Every time I talk about the All Spark Cube people ask “so what does it do?” The features of the All Spark are the reason it was built and sponsored by Adaptive Computing. The Cube was built to catch peoples’ attention and to demonstrate how Adaptive can take a chaotic mess and inject order, structure and efficiency. We wrote several examples of how the All Spark Cube can demonstrate the effectiveness of a complex data center. If you’re interested in building a monster of your own, hit up the link below for more information, schematics, and videos.

• 9 Gigapixel Photo Captures 84 Million Stars

  - by Jason Fitzpatrick

  The European Southern Observatory has released an absolutely enormous picture of the center of the Milky Way captured by their VISTA telescope–the image is 9 gigapixels and captures over 84 million stars. From the press release: The large mirror, wide field of view and very sensitive infrared detectors of ESO’s 4.1-metre Visible and Infrared Survey Telescope for Astronomy (VISTA) make it by far the best tool for this job. The team of astronomers is using data from the VISTA Variables in the Via Lactea programme (VVV), one of six public surveys carried out with VISTA. The data have been used to create a monumental 108 200 by 81 500 pixel colour image containing nearly nine billion pixels. This is one of the biggest astronomical images ever produced. The team has now used these data to compile the largest catalogue of the central concentration of stars in the Milky Way ever created. Want to check out all 9 billion glorious pixels in their uncompressed state? Be prepared to wait a bit, the uncompressed image is available for download but it weighs in at a massive 24.6GB. 84 Million Stars and Counting [via Wired] How Hackers Can Disguise Malicious Programs With Fake File Extensions Can Dust Actually Damage My Computer?

• DIY Halloween Decoration Uses Simple Silohuettes

  - by Jason Fitzpatrick

  While many of the Halloween decorating tricks we’ve shared over the years involve lots of wire, LEDs, and electronic guts, this one is thoroughly analog (and easy to put together). A simple set of silhouettes can cheaply and quickly transform the front of your house. Courtesy of Matt over at GeekDad, the transformation is easy to pull off. He explains: It’s really just about as simple as you could hope for. The materials needed are: black posterboard or black-painted cardboard; colored cellophane or tissue paper; and tape. The only tools needed are: measuring tape; some sort of drawing implement — chalk works really well; and scissors and/or X-Acto knife. And while you need some drawing talent, the scale is big enough and the need for precision little enough that you don’t need that much. For a more thorough rundown of the steps hit up the link below or hit up Google Images to find some monster silhouette inspiration.

• Acer Aspire 5542G overheating with ubuntu/kubuntu 12.04

  - by james

  I have an Acer Aspire 5542G laptop purchased couple of years ago. All these days, i used windows 7 on it . Then I tried ubuntu 12.04 . Everything was fine except the overheating issue. I updated ubuntu with all security fixes and available updates but nothing solved the problem. With idle use like internet browsing, the cpu fan speeds up a lot and i can feel very hot air coming from the vent (comparable to playing serious 3d game in windows). But it will not go to a point of freeze and shutdown. But as long as im using it, with no intensive tasks at all, the laptop stays too hot. This wasn't the case with windows7. In windows 7 the fan will not rotate at all with normal use. I heard there was manufacturing defect with some acer laptops, but i think it wasn't the case with my laptop since windows7 runs perfectly. I updated the bios to latest version. I cleaned dust in the vents. I tried kubuntu 12.04 up-to-date. Nothing solved the issue. My laptop specs are: CPU : AMD turion2 x2 M500 @ 2.2GHz GPU : AMD Mobility Radeon HD4570 3GB RAM and 320GB hard disk.

• Pick Up BioShock and Bioshock 2 for Price of a Big Mac Meal

  - by Jason Fitzpatrick

  Pre-ordering just opened on the third-installment of the highly-acclaimed horror-survival game series BioShock, BioShock Infinite. As part of the pre-order promotions, you can pick up a bundled copy of BioShock and BioShock 2 for a song. For the unfamiliar, BioShock is an atmospheric first-person-shooter backed up by an incredible storyline set in the underwater utopian-turned-dystopian city of Rapture. BioShock 2 continues the story in Rapture and the upcoming release (Febuary 2013) of BioShock Infinite takes place in the same game universe but fifty years before the events of the first two installments. If that seems like the kind of game you could dig into, Amazon has the Windows-platform version of BioShock and BioShock 2 bundled together for a scant $7.49–81% off the Steam and general retail price. The best part about the promotion is you can either download the games from Amazon or, for those of you that use Steam, you can simply plug the game product key into Steam. You can read more about the both the original two games and the upcoming release at the official BioShock site.

• Using R on your Oracle Data Warehouse

  - by jean-pierre.dijcks

  Since it is Predictive Analytics World in our backyard (or are we San Francisco’s backyard…?) I figured it is well worth the time to dust of some old but important news. With big data (should we start calling it “any data analytics” instead?) being the buzz word and analytics the key operative goal, not moving data around is becoming more and more critical to the business users. Why? Because instead of spending time on moving data around into your next analytics server you should be running analytics on those CPUs. You could always do this with Oracle Data Mining within the Oracle Database. But a lot of folks want to leverage R as their main tool. Well, this article describes how you can do this, since 2010… As Casimir Saternos concludes in the article; “There is a growing awareness of the need to effectively analyze astronomical amounts of data, much of which is stored in Oracle databases. Statistics and modeling techniques are used to improve a wide variety of business functions. ODM accessed using the R language increases the value of your data by uncovering additional information. RODM is a powerful tool to enable your organization to make predictions, classify data, and create visualizations that maximize effectiveness and efficiencies.” Happy Analysis!

• How do I upgrade from ubuntu 9.10 to 12.10 on my Acer Aspire 3000

  - by 770

  I had my Acer Aspire 3000 as a dual boot XP/ubuntu 9.10 a couple years ago. I recently blew the dust of it and wanted to upgrade to 7/Ubuntu 12.10 so I began by formatting the Ubuntu side of the partition and apparently damaged the mbr as I could only get black screen with the error message: GRUB loading. error: no such partition grub rescue I then slaved the hdd to my win7 desktop and formatted the entire drive, both sides of the partition then reinstalled it in the Acer and tried to install win7. Upon starting the Acer I got the same error message: GRUB loading. error: no such partition grub rescue I then tried to reinstall Ubuntu 9.10 as I have an Ubuntu produced installation cd. Same result. Next day I received a new battery I had ordered for the Acer. I plugged it and the power supply in and hit the power button just to see if I at least could charge the battery but to my surprise Ubuntu 9.10 began to install, so I let it and it did. Now the hard drive shows 58 gb and 2.5gb partitions neither of which is formatted NTFS for/by windows. I am guessing that the GRUB/mbr was repaired somehow by the Ubuntu reinstallation. My question, should you choose to accept it; How can I get to my goal of dual boot win7/Ubuntu 12.10. I am a beginner and don't know much about linux or the terminology. Thank you for your thoughts and help.

• Reinstall TeamCity when Tomcat becomes corrupt

  - by dodegaard

  I've got a TeamCity 4 installation where tomcat has bit the dust with the following error "The APR Based Apache Tomcat Native library which allows for optimal performance in production environments was not found in java.library path". It appears this started happening once the JDK was installed on the server to allow for a compile. The JDK has been removed and the JRE reinstalled but still no go. My question is should I reinstall TeamCity completely or is there a way to simply reinstall tomcat so I don't hose the configuration? Your help is greatly appreciated.

• How is application virtualization implemented?

  - by noob_lurker

  I am trying to understand how software like App-V and sandboxie (http://www.sandboxie.com/) work. But for the life of me, I can't think of anything that could make this possible. How do they intercept API calls and trick the target software? If someone would say that it's just magic and pixie dust, I would believe them. Seriously though, are there any white papers that discuss solutions to this problem? If this is possible on the CLR level then that would be good but I'm willing to go native if I have to.
