• Windows 7 boot problem on a Lenovo Thinkpad Z61m 9450HAG

  - by Matt Taylor

  Hello, I recently did a full upgrade of windows 7 on my thinkpad, everything worked fine after up until the second reboot (the first reboot after some updates installed worked OK). At second reboot time the system would just black screen just before the Windows logo appears, disk/wireless/power/battery lights are all lit and the disk light is active (flickering). However, if I remove my battery and boot with just power it boots fine and quickly, and everything is OK. Any help on why this wont boot with battery plugged in is greatly appreciated - i need to take this battery out on the road/trains etc.... Cheers Matt

• Performance difference between MacBook Pro (2.8 GHz) vs Air (1.7 GHz)?

  - by jonathanconway

  I'm comparing these two Apple laptops: MacBook Pro (13", 2011 model): 2.8GHz dual-core Intel Core i7 processor with 4MB shared L3 cache 4GB (two 2GB SO-DIMMs) of 1333MHz DDR3 SDRAM AMD Radeon HD 6770M graphics processor with 1GB of GDDR5 memory on 2.4GHz configuration MacBook Air (13", 2011 model): 1.7GHz dual-core Intel Core i5 with 3MB shared L3 cache 4GB of 1333MHz DDR3 onboard memory Intel HD Graphics 3000 processor with 384MB of DDR3 SDRAM shared with main memory There's definitely a gap between them in terms of CPU speed and graphics, but what practical difference would this make on a day-to-day basis? On the one hand, I love the sleek, thin appearance of the Air. On the other hand, I don't want a machine that's going to be dog-slow when doing tasks such as running Virtual Machines, dual-booting to Windows and running multiple instances of Visual Studio, and maybe some light gaming. Is there going to be a major difference that makes the MacBook Pro a more attractive purchase?

• HP Compaq T20 Thin Clients & Windows Server 2008 R2: RDP Disconnects instantly.

  - by sinni800

  Hello, I have some HP Compaq T20 Thin Clients connecting to a Windows Server 2003. Now I want to upgrade to 2008 R2, so I tested a trial installation with remote desktop in administration mode. So I try to connect my T20 to the server and... It doesn't matter if I turn off encryption or not it disconnects with an generic error instantly. The T20s have Windows CE embedded with RDP 5.2 installed. Out of curiosity I tried Windows Server 2008 (no R2) and it worked! I tried the same with a Windows 7 machine set up with- no work. I can not update the T20s to Windows NT embedded for example because they only have a low amount of flash memory. It seems the "new" version of RDP coming from Windows 7 / Windows Server 2008 R2 is completely incompatible with the older 5.2 version. People are having the same problem here: http://social.technet.microsoft.com/Forums/en-US/winserverTS/thread/700488cd-a872-47e5-85a7-595f050afc10

• maildir in Windows for IMAP

  - by User1

  I'm interested in accessing my IMAP accounts offline. I found that maildirs are a simple way to make it work. I found that [offlineimap] takes care of almost everything in making the IMAP-maildir sync happen. Then, I can open the account in Mutt or Wanderlust client. One major problem, maildirs use colons in their filenames. Windows doesn't allow colons. I tried mount -f -s -b -o managed "d:/tmp/mail" "/home/of/mail" in Cygwin, but doing an echo test > /home/of/mail/test:file didn't work I'm thinking about ext2fs, but I need an ext2 partition somewhere. Can I make a file into a partition somehow? I don't want to start modifying my hard drive's partition table. Besides, does anyone know if ext2fs will support colons in filenames?

• virtual machines: optimal host os to run Windows XP guest os?

  - by user61132

  My department doesn't have the budget to upgrade my ailing Dell D620 laptop. However, I do have the option to buy my own personal computer, then use my company-issued ISO image to run Windows XP as my guest os using virtualbox or vmware. Therefore, last month, I bought an Acer AX3910-U3012 desktop that had Windows 7 as the host os (and 8G RAM). In short, I was disappointed with the performance while trying to run WinXP as the guest os. (It didn't perform much better than my laptop.) Just wondering what the optimal host os would be for running Windows XP as the guest os? (No, I can't use my company-issued ISO image to build the os for my personal computer.) FWIW, I'm willing to spend up to $2k if it's REALLY worth it, but would prefer to spend no more than $1k. Also, in an effort to cut costs, I'd prefer buy a desktop instead of a laptop. Thanks for any/all feedback.

• Update to Windows 8.1 without using Windows Store

  - by Hari

  I am currently using Windows 8 on my desktop PC. I want to upgrade to Windows 8.1. I heard that Microsoft provides this update through Microsoft Store for free. But in My home I don't have a faster internet connection. I downloaded a Windows 8.1 ISO from cafe, but when I started installing, it asks for a key. I typed my original Key for windows 8, but it didn't work. Is there any way for me to update to Windows 8.1 without an internet connection and without purchasing another key? Thank you

• SBS 2003 crashes often due to limited memory

  - by Sanoj

  I have a Windows SBS 2003 Std that regularly crashes, in about every 20th day. The only thing I can see in the logs is that used memory increases with about 30MB/day. The process that uses more and more memory is sqlservr. We don't have much installed on the server; a Point-Of-Sale-system that uses Pervasive SQL as database and an Accounting application. We just have 2GB of RAM and I could upgrade to 4GB but I think that this just delay the problem. Is there any solution to this problem? Could I limit sqlservr to some memory?

• Why does storage's performance change at various queue depths?

  - by Mxx

  I'm in the market for a storage upgrade for our servers. I'm looking at benchmarks of various PCIe SSD devices and in comparisons I see that IOPS change at various queue depths. How can that be and why is that happening? The way I understand things is: I have a device with maximum (theoretical) of 100k IOPS. If my workload consistently produces 100,001 IOPS, I'll have a queue depth of 1, am I correct? However, from what I see in benchmarks some devices run slower at lower queue depths, then speedup at depth of 4-64 and then slow down again at even larger depths. Isn't queue depths a property of OS(or perhaps storage controller), so why would that affect IOPS?

• unable to install new versions of linux on my PC

  - by iamrohitbanga

  I have an MSI-RC410 motherboard with onboard ATI Radeon XPress 200 series Graphics card. I have used OpenSuse-11.0 on my PC for over an year. but when I tried to upgrade to OpenSuse-11.1, I managed to install it only to find that several features were missing. for example /dev/cdrom was missing. Also install DVD of Fedora 11 did not work. I have also tried Ubuntu-9.10 live cd. When I boot from the CD i get the initramfs command prompt. Still able to install old versions of these OSs. What is the reason for this behavior? Does it have to do anything with the new version of the linux kernel not being compatible with my hardware? What should i do to install new versions of Linux?

• Difference in VISUAL STUDIO VERSIONS

  - by karthik ram

  I would like to understand some fundamental VS version differences, What is the difference between Visual Studio 2008 and Visual Studio 2008 Team System? Does the Team System 2008 include VS2008, TFS 2008 & Team Explorer 2008? Furthermore, what is the difference betwene Team System 2008 and Team Suite 2008? I beleive there are no more Team Suites or Team Systems in 2010? Does Visual Studio Ultimate 2010 include all Team System components, like TFS 2010 & Team Explorer 2010, so in effect it is like an upgrade of Visual Studio 2008 Team System? Or does TFS 2010 & Team Explorer 2010 need to be installed separately?

• Recover from a corrupted couchbase install

  - by jcolebrand

  We have a couchbase installation on a Windows 2008 R2 server that got corrupted (this was from before my tenure, now I want to clean it up). There is no add-remove entry in the Programs and Features list. There is no active service in services.msc. However, something still thinks Couchbase is installed. Shy of wiping the box (we aren't quite to "redeploy test environment servers at the push of a button" altho I'm working on it), how can I ensure that all remnants of couchbase installs prior are now gone? I believe the previous install was in the Couchbase 2.x range, but it may have been 1.7+ Running the installer again gives "Installer needs to update registry value in order to upgrade from the previous version. Please run installer again to continue."

• Server 2008 R2 .Net 4 Programs running from Network share won't work

  - by Lim

  we have several .Net Apps stored on a Network share on our old Server (Windows Server 2003). These Apps get called by Windows 7 32bit Clients and work perfectly fine. We recently wanted to upgrade our Server to Windows Server 2008 R2 and moved the Apps from the old share to our new share on the new Server. The problem started right afterwards since all of our .Net Programs won't start anymore from the new share (2008 R2). The Error that comes up is: "This application could not be started." and with a link to Microsoft: http://support.microsoft.com/kb/2715633 (This Error also shows up when i start a simple console HelloWorld from the server share created in VS2012) Does anyone have any Idea why this is not working anymore on the new Servershare? We've been searching for two days now with no result at all. Any Tips / Help / Questions appreciated :) Greetings Lim

• Software RAID 10 on Linux

  - by vpetersson

  For a long time, I've been thinking about switching to RAID 10 on a few servers. Now that Ubuntu 10.04 LTS is live, it's time for an upgrade. The servers I'm using are HP Proliant ML115 (very good value). It has four internal 3.5" slots. I'm currently using one drive for the system and a RAID5 array (software) for the remaining three disks. The problem is that this creates a single-point-of-failure on the boot drive. Hence I'd like to switch to a RAID10 array, as it would give me both better I/O performance and more reliability. The problem is only that good controller cards that supports RAID10 (such as 3Ware) cost almost as much as the server itself. Moreover software-RAID10 does not seem to work very well with Grub. What is your advice? Should I just keep running RAID5? Have anyone been able to successfully install a software RAID10 without boot issues?

• xDebug on Zend Server CE under Windows XP

  - by Hippyjim

  I have Zend Server installed on my Windows XP development machine, installed when I was naive and didn't know that Eclipse was going to become so suck so badly for PHP development. I've made the upgrade to Netbeans, but for debugging they only support xDebug. To be fair I've never used "proper" debuggers before, but other folks have raved about them so I thought I'd give it a try. I followed some directions on the Zend forum about how to install xDebug on Zend server, disabling Zend Debugger in the process. The xDebug "custom installation instructions" wizard tells me that my PHP was compiled with an unsupported compiler (MS VC8), and won't let me download anything. I tried a couple of the other xDebug binaries, but they just refused to load. So I'm left without a debugger option. Does anyone know how I can change the compiler of the php version I have installed so I can use a debugger in Netbeans? or how else i can get xDebug to install on Zend Server?

• Outlook 2003 (with Exchange 2007) error: You cannot respond to a meeting without an Organizer

  - by Hissohathair

  The company recently upgraded to Exchange 2007. Since the upgrade users who are still on Outlook 2003 (SP3) get the following error for some meeting requests: You cannot respond to a meeting without an organizer. You must add an Organizer field to the item. The item has an organizer field filled in. Exchange is 2007 with SP1 MS Office (incl Outlook) is 2003 with SP3 Some users are using iPhones to accept / reject meetings. The iPhones never get an error like this. There are no delegates for the user attempting to accept or reject the meeting. Sometimes the meeting was previously accepted, sometimes not. We have not detected a pattern in the meeting requests that trigger the issue. I've found a few people asking the same question on other websites but no answers. Experts Exchange claims to have an answer but from looking at the discussion at the bottom of the page I'm pretty sure they don't.

• How to have file/folder icons use a relative path?

  - by Memor-X

  On my portable hard drive I set icons for almost every organized folder. All these icons are located in an Icons folder located on the root directory of the same hard drive. When I change the drive letter of the hard drive (well I don't, windows does automatically sometimes) these icons are lost. So far this hard drive is assigned to F: While it's not a problem now, it may becomes a problem if I upgrade my computer or get a new one and the F: Drive is already taken up for something else. It's also annoying on networks where F: is mapped to a network drive.

• My server is running out of memory, despite having all swap free

  - by Biohazard

  I am using Debian 6 (Squeeze). The server has 4gb of memory in it, and 8gb of swap. I'm starting to get memory alloc errors at high application load times, but from top command: Mem: 4055944k total, 3915436k used, 140508k free, 10444k buffers Swap: 7999480k total, 0k used, 7999480k free, 3604496k cached The system isn't even trying to use the swap? Why would this be happening? I would like to upgrade the primary memory, but this isn't possible just right now. Thanks.

• Excel 2003 Freezes When Worksheet with PivotTable Selected

  - by Max

  All of the sudden, my Excel 2003 began an odd behavior today. Whenever I click on a worksheet tab that has a PivotTable on it, I become unable to click on any other tabs or on the menu with the options to minimize, maximize, and size at the top left of the worksheet window. I am left unable to click on the other tabs until I double-click inside a cell in the PivotTable worksheet and get a blinking curor as if to type. Then, I can navigate to other tabs normally. I can't think of any major changes I have made to my computer in the last day that would have caused this. I did instiall PC Tools antivirus over a week ago, and since that time have noticed my computer behaving in odd ways, but excel has been just fine until now. Does anyone have any thoughts on what might cause this? Thanks so much.

Maybe u know how?

• (simple) linux HA with vmware vsphere?

  - by derhelge

  I hope my upcoming question is specific enough, and you are able and willing to support :-) We have several openSUSE VMs in an ESX-Cluster (three ESX-Servers) with an attached iSCSI-SAN. All of those Linux VMs are "single point of failure"-configured, which means in the case of a Web-Server: LAMP, storage, etc. everything on this machine. This was very simple and in case of a failure (in the last years: kernel panics or apache crashes) a simple reboot triggered by a script did it. But the problem is: How to upgrade/maintain the w(eb-)application or the underlying OS without downtime? This wasn't really managable and i did this in the early morning ;) How can i achieve a "simple" High-Availability Cluster now? I thought of: DRBD with heartbeat with 2 VMs. And for the storage a RDM (raw device mapped) LUN and change the read-write-permissions for both VMs. Is this a good idea? Anyone has a better solution?

• Windows 8.1 fresh install with Windows 8 licence

  - by typ1232

  I purchased Windows 8 online from Microsoft a while ago. Today Windows 8.1 was released as a free update to Windows 8 users over the Windows Store. I was planning to do a fresh install of Windows 8.1 to have a clean system again and UEFI support because I got new hardware since the Windows 8 installation. So my questions are: Where do I get the ISO installation medium for Windows 8.1 64-bit? I tried this microsoft site where I initially got my Windows 8 ISO from, but when entering my Windows 8 key in the Windows 8.1 installer, it says the key is wrong. Even if I get the ISO, will my old key work? I'm concerned because it didn't work in their installer (see previous point) Do they seriously want me to reinstall Windows 8 and after that upgrade to Windows 8.1 through their Store?!

• What type of VPS stats should I look for?

  - by Dave

  I have a few websites that average a total of 10,000 uniques a day across my network. I also have a few mobile apps that pull xml data maybe 5,000 calls a day. My sites aren't anything major just a few wallpaper websites and few other small sites, nothing real database intensive. I currently own a dedicated server and I feel like it's overkill for my network. I'm looking into getting a Virtual Private Server (VPS). I was just wondering what kind of stats I should be looking for to support my network of sites. Thanks

• Create Google Maps screenshots at regular intervals

  - by Dave Jarvis

  Background People are concerned that building a pipeline to the West Coast of Canada will increase the number of oil tankers, thus increasing the probability of a major oil spill, thereby creating an environmental catastrophe. The AIS Live Ships Map website captures real-time Marine Traffic updates using a Google Maps interface. While it is possible to obtain data from an AIS data feed, often the feeds are either pay-for-use, or otherwise encumbered with license restrictions. Problem The AIS Live Ships website presents a map in the browser: The map above has had its location interactively changed to focus on the area in question: the northern straight of Vancouver Island. Question How would you create a service that captures the map every 30 minutes and that could run, with neither user-intervention nor a significant memory footprint, for a few years? Idea #1 Create a virtual machine. Install and run a light-weight browser. Use Shutter to take captures at regular intervals. Idea #2 Use Python's Ghost Webkit to automate the captures. Thank you!

• Bandwidth sizing for simultaneous RDP sessions

  - by Gareth Marlow

  We're doing some DR scenario planning which will require up to 150 users to RDP into their desktop machines (mainly running Windows XP) over our VPN. We have a 2mbit uncontended internet connection at the moment but there's scope to upgrade this and also to use a secondary SDSL line to give us more bandwidth. Typical bandwidth figures I've seen suggest to plan for 64kbps per session, which works out to 9.6mbps in total. I'd like to know: Does anyone have any real-world data which would support these estimates? Are there any operational 'gotcha's that we need to be aware of? Thanks!
