• Wifi not working on Acer Aspire One D270

  - by Dani

  brand new baby linux user here, never used Ubuntu or any other linux OS before, so be gentle and use short words! I installed Ubuntu 12.04 on my new Acer Aspire One D270-F61C/KF netbook (it's a Japanese computer which had Japanese windows preinstalled, and I decided to take the plunge and try Ubuntu because English Windows costs the earth and stars). Wifi isn't working; I enter my wireless password, it tries to connect for a while, then asks for my password again. And KEEPS ASKING, every few minutes. Wired connection works fine. Wireless card is a Broadcom BCM4313; I have the "additional drivers" checked and installed (I tried unchecking and then reinstalling them in case that would help, no joy, and now my home wifi connection isn't showing up in the list of available connections, argh). I've done a lot of googling and I gather there's a lot of issues with Broadcom cards, but some of the answers are for earlier ubuntu builds and many of them are a bit confusing for a new user. I gather I need to try installing some new drivers other than the proprietary ones provided, but I'm having trouble figuring out how that's done. Anyone got some simple, step by step instructions for me? Please bear in mind, TOTAL N00B. (EDIT): OKAY, got it fixed finally; after suggestions on the Ubuntu forums and messing around with drivers, what finally worked was installing Wicd. Not... using Wicd, for some reason, just installing it fixed it. ...I CHOOSE NOT TO QUESTION IT.

• Why does waking a PC up with a timer act differently than with the power button?

  - by Dan Rasmussen

  I have a Windows 7 machine set up as a server. It has no monitor and is only accessed through remote desktop. I set up two scheduled tasks, one to put the computer to sleep at night and another to wake it up in the morning. When it's woken up from sleep via a timer, it stays awake for only a couple minutes before going back to sleep. When woken up by pushing the power button, however, it stays awake all the way until the sleep timer. Why does my PC behave differently in these two scenarios? I have set the PC not to prompt for a user's password on wake, since I worried that the login screen might follow different power rules. I tried SmartPower Configuration but had the same problems. I can provide more details if questions are asked in the comments, but I'm not sure what's relevant.

• Great Indian Developer Summit Wrap-Up

  Last week I spoke at the Great Indian Developer Summit in Bangalore, India. This was my second year speaking at GIDS, so it was great to be back. Before the event Teleriks Team Fantastic Four set up the booth and then hit McDonalds for a Maharaja Mac. Remember India does not eat beef, so we HAD to go to McDonalds and check it out! Imagine a McDonalds without a hamburger. Totally awesome. (Though we all preferred the McAloo, a potato patty sandwich.) The event is really 4 conferences in 4 days. One day each on: .NET, Web, Java, and Seminars. On the Day 1 (.NET) I spoke on: Building Data Warehouses Building Applications with Silverlight and .NET (and sharing the business logic) What's new in SQL Server 2008 R2 No computer malfunctions like last year, my sessions went smooth. This is rapid fire presenting: only 50 minute sessions! With so little time, I had almost ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Fabric and cygwin don't work with windows UNC paths

  - by tcoopman

  I have some strange problems with fabric deployment to Windows Server 2008r2. The thing I try to accomplish is to copy some files to a shared folder with a fabric script (this script does a lot of other things too, but only this step gives me problems). This is the problem: When I try to access a UNC(Universal Naming convention) path I always get access denied kind of answers if I run the script in fabric. When I run the command in an ssh prompt (same user) it works fine. Examples: cmd: robocopy f:/.... //share result: in ssh this works fine, in fabric I get "Logon failure: the user has not been granted the requested logon type aat this computer." cmd: cd //share result: in ssh this works fine, in fabric I get "//share: Not a directory" Further information: uname -a and whoami return exact the same thing in fabric and ssh. I also tried things like mount, net use, but these commands all have kind of the same problem.

• Internet Explorer will not open Office files

  - by geekrutherford

  An issue was brought to my attention today at work where certain users were unable to open Office files (specifically Excel) from Internet Explorer 7.   The user would click on a button which simply generated an inline JS call to open a pop-up pointing to the .xlsx file on the server. IE would open the pop-up and then shortly thereafter the pop-up would disappear without the file ever opening.   I tweaked the security settings in the users browser...added the site to the list of trusted sites and lowered the security settings to Medium-Low. This allowed IE to at least prompt with the Save or Open message. Clicking either open resulted in "Internet Explorer Could Not Open the Site...".   Perturbed, I retreated back to Geek Central (aka my desk) and modified my application such that instead of simply pointing the browser to the file and now used Response.TransmitFile() to stream it to the browser instead. I thought to myself "this is perfect, it has to work!!!". Alas, no luck.   Bewildered and confused and returned to the lone users computer and started looking around the various IE options. I stumbled upon "Clear SSL State" under the "Content" tab. This appears to clear out all SSL certificates on the client forcing it to refresh. Doing this in concert with resetting the security levels for all zones back to their defaults seemed to do the trick.

• Recover backup copy of a ubuntu linux installation on a usb stick using dd

  - by user10826

  Hi, I installed Ubuntu 10.04 on a usb stick in persistent install mode. So I could boot the laptop or my desktop computer with the stick, at boot time. Once I needed the 8GB stick for another purposes so I thought about coyping it to my desktop doing from mac os x: dd if=/dev/disks3s of=/Users/jack/Desktop/usb_copy Now I am trying to do the opposite, after having used the stick, which was formatted to NTFS, just doing dd if=/Users/jack/Desktop/usb_copy of=/dev/disks3s but although I can see that almost of the files are there, I can not boot again. IT is also strange the the file permissions are kind of strange, something like _user What can I do ? Thanks

• Debugging Windows Service Timeout Error 1053

  - by Joe Mayo

  If you ever receive an Error 1053 for a timeout when starting a Windows Service you've written, the underlying problem might not have anything to do with a timeout.  Here's the error so you can compare it to what you're seeing: --------------------------- Services --------------------------- Windows could not start the Service1 service on Local Computer.   Error 1053: The service did not respond to the start or control request in a timely fashion. --------------------------- OK   --------------------------- Searching the Web for a solution to this error in your Windows Service will result in a lot of wasted time and advice that won't help.  Sometimes you might get lucky if your problem is exactly the same as someone else's, but this isn't always the case.  One of the solutions you'll see has to do with a known error on Windows Server 2003 that's fixed by a patch to the .NET Framework 1.1, which won't work.  As I write this blog post, I'm using the .NET Framework 4.0, which is a tad bit past that timeframe. Most likely, the basic problem is that your service is throwing an exception that you aren't handling.  To debug this, wrap your service initialization code in a try/catch block and log the exception, as shown below: using System; using System.Diagnostics; using System.ServiceProcess; namespace WindowsService { static class Program { static void Main() { try { ServiceBase[] ServicesToRun; ServicesToRun = new ServiceBase[] { new Service1() }; ServiceBase.Run(ServicesToRun); } catch (Exception ex) { EventLog.WriteEntry("Application", ex.ToString(), EventLogEntryType.Error); } } } } After you uninstall the old service, redeploy the service with modifications, and receive the same error message as above; look in the Event Viewer/Application logs.  You'll see what the real problem is, which is the underlying reason for the timeout.

• Photo Management Software for OS X That Supports Multiple Library Locations

  - by Lance Rushing

  I'm looking at the possibility of changing our photo management software. Thinking about Aperture or Lightroom. And want to know if either supports: Having folders/libraries on separate harddrives/Volumes. Tolerates having network folders occasionally connected Snappy interface A solid enough piece of software as not to crash or behave weirdly. [ so the wife doesn't get stuck and have to call me ;) ] Background The wife is photographer and I'm the computer programmer. Our current setup is Picasa, with a "Recent/Working" folder on the local iMac harddrive, and "Archive" folders on NFS mounted Linux Server, Raid 5, for redundant and extra storage capacity. (the Linux server also syncs with Amazon's EC2) Picasa is doing OK, but I get annoyed when it doesn't do behave properly. Usually around issues when the Linux disk isn't mounted. And overall, I wish Picasa seemed a little more polished and snappier. Thanks, Lance

• Diagnose Slow Video Playback during Editing [closed]

  - by chadejah Hunter

  Possible Duplicate: I Want To Start Editing Videos But My Computer Moves Slowly I am using Windows 7 Home Premium on a PC with AMD 64bit Athlon Processor 2850e @ 1.80GHz, 2GB RAM, and a NVIDIA GeForce 6150SE nForce 430 graphics card I am using Pinnacle Studio 15 HD Ultimate.

When the sound ends the picture continues to play and it speeds up. I updated the video card today, restarting the PC but get the same behaviour. Does anyone have any suggestions what I can do to get video working smoothly while editing?

• Built-in webcam on Asus laptop missing under imaging devices in Windows 7

  - by dave

  My built-in webcam for U43JC Asus laptop (Windows 7 32 bit) did not work, saying The camera is being used by another program. I searched on the net to solve the problem and the solution that seemed to be working was to remove usb2.0 uvc 1.3m webcam and restart the computer and the webcam will automatically re-install. However, not only did the webcam not re-install automatically, but the webcam is still not working. Things have gotten only worse that now I'm missing the webcam under Imaging Devices. I even tried recovering Windows to the factory state, however, the webcam was still missing. What can I do to restore my usb2.0 uvc 1.3m webcam?

• Alienware M17x R3: Possible downclock

  - by Ywen

  I installed recently Kubuntu 11.10 32 bits (had graphics driver issues, wanted to try on 32 bits version) on my new Alienware M17x, with a Core i7-2670QM CPU. Cores are supposed to be clocked at 2.2 GHz, however the output of $ cat /proc/cpuinfo | grep -i "hz" gives me: model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 If useful, the AC adapter is plugged in (yet the ouput is the same when the computer is powered only by the battery) and I have Firefox and Eclipse running. Does /proc/cpuinfo reflect a possible automatic downclock made to save power if processor load is low or is this output abnormal? EDIT: Ok, I checked and yes, the ouput does vary in function of the load. I reach 2.2 GHz when needed. But my following problem remains. I was checking my CPU clocking because I experienced poor performances when reading 720p video files on Ubuntu with VLC or mplayer when on battery (and I believe VLC by default only uses CPU, not GPU to decode), whereas I haven't got such problems with VLC on Windows (which made me think it wasn't coming from a BIOS option, plus every option in the BIOS regarding the CPU is turned ON).

• HTTP 400 error for all websites

  - by Jason Sherman

  A couple of days ago, I started getting HTTP 400 responses from all websites. Nothing will go across port 80. However, everything works if I connect to VPN. The weird thing is, without VPN, other things still work; such as IM and anything else that doesn’t use port 80. Pinging also works. I haven’t noticed this behavior on any other computer on my network. The kicker is, if I log on as a local admin, everything works fine!!! I haven’t installed anything in the last couple weeks and I don’t remember changing any configuration. I ran Forefront and HouseCall and neither found any problems.

• Google Chrome auto-clicker extension?

  - by Joel Murphy

  I'm looking for an auto-clicker that will auto click page elements in Google Chrome. Standard auto-clickers work fine, but I'd like to continue working on my computer without having to keep Google Chrome open. Does anyone know of any extensions that offer this functionality? Anything that allows me to specify an element to be clicked on, or set screen co-ordinates within a webpage and will click away until I decide to stop the script would be perfect. I've tried looking at macro extensions, but they don't seem to offer the functionality I want. Can anybody suggest a particular extension? Thanks in advance.

• Raspberry Pi and Java SE: A Platform for the Masses

  - by Jim Connors

  One of the more exciting developments in the embedded systems world has been the announcement and availability of the Raspberry Pi, a very capable computer that is no bigger than a credit card.  At $35 US, initial demand for the device was so significant, that very long back orders quickly ensued. After months of patiently waiting, mine finally arrived.  Those initial growing pains appear to have been fixed, so availability now should be much more reasonable. At a very high level, here are some of the important specs: Broadcom BCM2835 System on a chip (SoC) ARM1176JZFS, with floating point, running at 700MHz Videocore 4 GPU capable of BluRay quality playback 256Mb RAM 2 USB ports and Ethernet Boots from SD card Linux distributions (e.g. Debian) available So what's taking place taking place with respect to the Java platform and Raspberry Pi? A Java SE Embedded binary suitable for the Raspberry Pi is available for download (Arm v6/7) here.  Note, this is based on the armel architecture, a variety of Arm designed to support floating point through a compatibility library that operates on more platforms, but can hamper performance.  In order to use this Java SE binary, select the available Debian distribution for your Raspberry Pi. The more recent Raspbian distribution is based on the armhf (hard float) architecture, which provides for more efficient hardware-based floating point operations.  However armhf is not binary compatible with armel.  As of the writing of this blog, Java SE Embedded binaries are not yet publicly available for the armhf-based Raspbian distro, but as mentioned in Henrik Stahl's blog, an armhf release is in the works. As demonstrated at the just-completed JavaOne 2012 San Francisco event, the graphics processing unit inside the Raspberry Pi is very capable indeed, and makes for an excellent candidate for JavaFX.  As such, plans also call for a Pi-optimized version of JavaFX in a future release too. A thriving community around the Raspberry Pi has developed at light speed, and as evidenced by the packed attendance at Pi-specific sessions at Java One 2012, the interest in Java for this platform is following suit. So stay tuned for more developments...

• Using PowerShell, in Active Direcotry, how would I change all the DNS A records that have a given IP to a new IP?

  - by djsumdog

  We've been moving data centers and I have a lot of old records that were not correctly but in DNS as CNAME records, but A records that have a direct IP (e.g. 192.168.100.n) and they're all moving to a new subnet (10.19.100.n). I just need to write a powershell script to change all those records. I found this site: http://www.indented.co.uk/index.php/2008/12/30/administering-microsoft-dns-in-powershell/ and from it I made this simple script: $dnsServer = "meldc2" $scope = New-Object Management.ManagementScope("\\$dnsServer\root\MicrosoftDNS") $path = New-Object Management.ManagementPath("MicrosoftDNS_Zone") $options = New-Object Management.ObjectGetOptions($Null,[System.TimeSpan]::MaxValue, $True) $ZoneClass= New-Object Management.ManagementClass($scope,$path,$options) $Zones = Get-WMIObject -Computer $dnsServer -Namespace "root\MicrosoftDNS" -Class "MicrosoftDNS_Zone" $Zones | Get-Member foreach($Z in $Zones) { $Z | Select-Object Name,DsIntegrated,ZoneType,Reverse,Data } but that only gets me a listing of root zones. I don't understand how to iterate over all the entries in each of the zones. Also, all the examples I've seen involve adding new zones, but there aren't any examples I can find on modifying existing A records.

• Strange DNS problem [seems to be IPv6 issue]

  - by Homer J. Simpson

  Hi, I'm experiencing strange problems with my Kubuntu 9.10 when doing DNS requests from various applications. The requests are extremely slow, so loading any pages in Firefox or Konqueror, doing package installations in Kpackagemanager and other apps is really painful, while for example Opera doesnt have any problems, and ping is normally fast as well for DNS pings. I checked the proxy settings of both the used applications as well as of the general system and there are none, so to me it doesn't seem as there was something inbetween.. Does anybody have an idea on what to check for possible problem sources or how to solve this ? I'm behind a DSL home router which does the DHCP (and works well with my other computer). Any kind of advice would be really helpful. Edit: It seems to be some kind of IPv6 problem, as I could get it to work by disabling IPv6 explicitly in Firefox. Is there a general solution to this ?

• Packet loss with all adapters on one PC only on the LAN

  - by Enigmativity

  I have a Windows 7 64-bit machine that is losing up to 20% of IP packets on both adapters - wireless & LAN. Browser traffic appears to be affected the most, but it is happening to all protocols. All other computers on the network are functioning fine. If I ping from my faulty machine to any machine on the LAN (wired or wirelessly), including the router/gateway and internet sites, I get up to 20% packet loss. If I do the following commands: ipconfig /release ipconfig /renew then I sometimes get my network performance back for a matter of a few seconds to less than a couple of minutes. Rebooting also works for a short period of time. This problem has been occurring for a couple of months and is getting worse. The computer used to work just fine. I updated the wireless adapter firmware the other day with no effect. Does anyone know what is happening?

• Compiling zip component for PHP 5.2.11 in MAMP PRO

  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.

• Install Windows 8 64-bit over the top of Windows 8 32-bit

  - by Andrew Gee

  I currently have Windows 8 32-bit installed from MSDN (I didn't realise at the time that my processor supports 64-bit). I understand that you can't upgrade within Windows 32-bit to 64-bit directly from the ISO. I have burned the ISO to a DVD, and have attempted booting from this drive. The problem I am encountering: The operating system couldn't be loaded because a required file is missing or contains errors. File: CI.dll Error code: 0xc0000221 You'll need to use the recovery tools on your installation media. If you don't have any installation media (like a disc or USB device), contact your system administrator or PC manufacturer.

• 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?
