• 32 bit programs can't access Internet in Windows 7 64 bit

  - by korona

  I recently got a new ASUS laptop with Windows 7 Home Premium pre-installed. It worked OK for a while but a couple of days ago, suddenly I couldn't access the Internet any more. After narrowing down the problem, I've reached the conclusion that what's happened is that 32 bit programs are suddenly not able to use the Internet, but 64 bit applications work just fine. Examples of programs that DON'T work any more: Google chrome Firefox Internet Explorer 8 World of Warcraft Examples of programs that DO work: Internet Explorer 8 (64 bit) ping (command line) nslookup (command line) ftp (command line) I'm pretty sure that those command line apps are 64 bit native. A re-install of Windows using the recovery partition on the laptop did fix the problem temporarily, but now it's back again. And I seem to be stuck between a rock and a hard place getting someone to take the responsibility for this; the vendor says to talk to ASUS, ASUS says it's a software issue, and Microsoft doesn't give support on OEM licenses... Does anyone know how to solve this issue?

• Cheap ways to do scaling ops in shader?

  - by Nick Wiggill

  I've got an extensive world terrain that uses vec3 for the vertex position attribute. That's good, because the terrain has endless gradations due to the use of floating point. But I'm thinking about how to reduce the amount of data uploaded to the GPU. For my terrain, which uses discrete / grid-based vertex positions in x and z, it's pretty clear that I can replace my vec3s (floats, really) with shorts, halving the per-vertex position attribute cost from 12 bytes each to 6 bytes. Considering I've got little enough other vertex data, and an enormous amount of terrain data to push into the world, it's a major gain. Currently in my code, one unit in GLSL shaders is equal to 1m in the world. I like that scale. If I move over to using shorts, though, I won't be able to use the same scale, as I would then have a very blocky world where every step in height is an entire metre. So I see these potential solutions to scale the positional data correctly once it arrives at the vertex shader stage: Use 10:1 scaling, i.e. 1 short unit = 1 decimetre in CPU-side code. Do a division by 10 in the vertex shader to scale incoming decimetre values back to metres. Arbirary (non-PoT) divisions tend to be slow, however. Use (some-power-of-two):1 scaling (eg. 8:1), which enables the use of a bitshift (eg. val >> 3) to do the division... not sure how performant this is in shaders, though. Not as intuitive to read values, but possibly quite a bit faster than div by a non-PoT value. Use a texture as lookup table. I've heard that this is really fast. Or whatever solutions others can offer to achieve the same results -- minimal vertex data with sensible scaling.

• Adding Exchange Multi Tenant to an existing Exchange Network

  - by TiernanO

  I currently have an Exchange 2010 SP1 server in house, and due to some changes, it looks like i will need Multi Tenant support for a few extra domain names. Looking at the documentation i have found so far, it only mentions multi tenant support when upgrading from 2010 RTM - SP1, and not what you do if you have already got 2010 SP1 installed. So, from what i can gather, i have a few options: Install a new Exchange server with Multi Tenant support and migrate DBs over Back everything up and start again Something else... Any suggestions would be greatly appreciated... Thanks.

• How do I stop video tearing? (Nvidia prop driver, non-compositing window manager)

  - by Chan-Ho Suh

  I have that problem which seemingly afflicts many using the proprietary Nvidia driver: Video tearing: fine horizontal lines (usually near the top of my display) when there is a lot of panning or action in the video. (Note: switching back to the default nouveau driver is not an option, as its seemingly nonexistent power-management drains my battery several times faster) I've tried Totem, Parole, and VLC, and tearing occurs with all of them. The best result has been to use X11 output in VLC, but there is still tearing with relatively moderate action. Hardware: MacBook Air 3,2 -- which has an Nvidia GeForce 320M. There are two common fixes for tearing with Nvidia prop drivers: Turn off compositing, since Nvidia proprietary drivers don't usually play nice with compositing window managers on Linux (Compiz is an exception I'm aware of). But I use an extremely lightweight window manager (Awesome window manager) which is not even capable of compositing (or any cool effects). I also have this problem in Xfce, where I have compositing disabled. Enabling sync to VBlank. To enable this, I set the option in nvidia-settings and then autostart it as nvidia-settings -l with my other autostart programs. This seems to work, because when I run glxgears, I get: $ glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 303 frames in 5.0 seconds = 60.500 FPS 300 frames in 5.0 seconds = 59.992 FPS And when I check the refresh rate using nvidia-settings: $ nvidia-settings -q RefreshRate Attribute 'RefreshRate' (wampum:0.0; display device: DFP-2): 60.00 Hz. All this suggests sync to VBlank is enabled. As I understand it, this is precisely designed to stop tearing, and a lot of people's problem is even getting something like glxgears to output the correct info. I don't understand why it's not working for me. xorg.conf: http://paste.ubuntu.com/992056/ Example of observed tearing::

• How much ethical is to accept second offer while serving notice period for first company? [closed]

  - by iammilind

  I had got an offer from a company X 2 months back. Though the compensation was pretty good, I asked for more. They declined and I continued my search for the best. I was expecting good companies (Y, Z) will contact me, but that din't happen. Then 2 months later, now I re-approached company X again and they issued me the same offer. I accepted it, resigned from my current company and serving the notice period (2 months). Now the twist: I got calls from Y and Z (good companies). They definitely give better compensation. If they select me then my plan is to accept the better offer from Y/Z and inform the X immediately that I have got better opportunity, so I will not be able to join the company... Is this ethical ? [Edit Note: I have to just send an acceptance email (i.e. no contract signing) which doesn't legally bind me to join that company. So, legally I am not doing anything wrong. However, I am worried that if I am doing right/wrong ethically.]

• Managing MS Exchange server-side email rules on Mac OS X?

  - by Doug Harris

  Has anybody found an easy way to manage server-side rules from Mac OS X? Here's a brief list of what I know doesn't work: Entourage 2008 - it supports client rules, but not server rules. No good, there are certain actions that should happen before I open my laptop or check my email on my iPhone. Apple Mail - same as Entourage, but at least I don't get as frustrated since, unlike Entourage, this isn't a Microsoft product. Web mail (aka Outlook Web Access) - perhaps you can manage rule in the fancy version which Exchange serves to IE, but not with the browsers available on a Mac. I manage this now by launching a VMWare virtual machine running Windows XP and Outlook. I don't count that as an easy way. Update, post release of Office 2011 Does MS Outlook 2011 have the ability to manage server-side rules? Update, post installation of Office 2011 No. Outlook 2011 doesn't have this ability. I've already removed my account from Outlook and switched back to Apple Mail and iCal

• Laptop crashes when connecting to external harddisk

  - by Gnot

  I recently had a problem with my laptop. when I booted up the machine, I would get a SMART failure error message and when I pressed F1 to continue, it would take a very long time to boot and it would come back to the same error message again. Thinking that my hard disk was dying, I bought a new hard disk and installed on my laptop and so now my laptop is alright. However I need to recover data from that old hard disk, so I bought an external hard disk case and placed the old hard disk onto the case and connected to my laptop with USB. The first few times when I connected, I could see the files from the old hard disk and managed to copy some files over although it took extremely long to transfer. But now whenever I connect to the old hard disk, after a few minutes, my laptop will crash and re-boot. Do you think my old hard disk is dead beyond repair? Or you can offer some help here? Any assistance would be appreciated!

• Accessing a storage-side snapshot of a cluster-shared volume

  - by syneticon-dj

  From time to time I am in the situation where I need to get data back from storage-side snapshots of cluster shared volumes. I suppose I just never figured out a way to do it right, so I always needed to: expose the shadow copy as a separate LUN offline the original CSV in the cluster un-expose the LUN carrying the original CSV make sure my cluster nodes have detected the new LUN and no longer list the original one add the volume to the list of cluster volumes, promote it to be a CSV copy off the data I need undo steps 5. - 1. to revert to the original configuration This is quite tedious and requires downtime for the original volume. Is there a better way to do this without involving a separate host outside of the cluster?

• How do networking ports work? Can I configure the ports that client and server use?

  - by joedotnot

  Let's say i have a "server" program listening on address 1.2.3.4:69 (i.e. remote port 69) When i connect from a "client" program to it, typically i would specify the IP address + port of the target or server system; But what port would the client be using ? And how does the server know which port to connect back to the client on? I understand this question is very general, but just wanting to get a general feel for how things work. Then extending this to a specific protocol, say FTP (typical port 21), can I change it such that the server uses port 69, but the client uses port 100? And similarly, for Remote Desktop in WinXP (typical port 3389), i know how to change the server port to be something other than 3389, but how does one change what port the client uses (if at all possible)?

• Is there a convenient method to pull files from a server in an SSH session?

  - by tel

  I often SSH into a cluster node for work and after processing want to pull several results back to my local machine for analysis. Typically, to do this I use a local shell to scp from the server, but this requires a lot of path manipulation. I'd prefer to use a syntax like interactive FTP and just 'pull' files from the server to my local pwd. Another possible solution might be to have some way to automatically set up my client computer as an ssh alias so that something like scp results home:~/results would work as expected. Is there any obscure SSH trick that'll do this for me? Working from grawity's answer, a complete solution in config files is something like local .ssh/config: Host ex HostName ssh.example.com RemoteForward 10101 localhost:22 ssh.example.com .ssh/config: Host home HostName localhost Port 10101 which lets me do commands exactly like scp results home: transferring the file results to my home machine.

• Options not available anymore in my Samsung 932bw lcd

  - by Sávio Mendes

  I think a friend messed up something in my monitor. I left him playing a game and when i came back, i noticed that the brightness was very high. I tried to change it but i couldn't, brithness, contrast, color warm and a few other options are marked as "not available" (he probably adjusted the brightness and changed something else too, that it's causing this thing). I updated the monitor driver, the vcard driver, plugged the monitor in other pc (I'm connected through dvi, but in the other pc i plugged through rgb) but nothing fixed it. Is there someway to force reset all the options or something like that to fix this? (I'm running Win7 RC1 but I don't think that it has something to do with it, it was working perfectly until he messed it up, and the other pc where I plugged it, runs winxp and the problem occurs too. And it doens't look like a the monitor is broken, it works like it always did, just these options are marked "not available" now...)

  Situation I am running a RHEL server via a VM on my laptop. I have a win7 desktop sharing out a folder and the VM on my laptop running RHEL6 has a CIFS windows mount at \mnt\win When I go to unmount the device I get a device is busy message. So I went to my laptop and check to see if there were any users connected to the share, since it listed none I turned off sharing. I went back to my RHEL instance and attempted another umount \mnt\win but received the same error. Question What are other alternatives to unmounting a shared drive?

• what to use instead of laptop-mode?

  - by playcat

  hello, i have ubuntu 10.10 64bit on hp 6735s (turion processor). it overheats, and i'm forced to use turion power control in order to keep core temperature to a reasonable level. one more measure that i use is putting my processors to conservative mode. that way, i'm perfectly happy with its performance, and heat is where it should be. however, after my latest upgrade, something happened - cores are back to ondemand by default, and i'm not sure if turionpowercontrol is working any more (ps axu | grep urion shows no process). in addition, i read somewhere that laptop-mode uses hdd spindown for preserving data/energy, and that hdds have only a limited amount of those spindowns, so laptop-mode usage can actually shorten the life of my hdd. i'm wondering if there is a good way to set my cores to automatically go to conservative mode? also, what's the good way to see what is the voltage my cores use? on windows i use cpuz tools. thx and sorry for the long explanation.

• xcopy files and directory

  - by user1044937

  I have a folder named "C:\Jobs\job#1" , "C:\Jobs\job#2" "C:\Jobs\job#3" etc and a lot of directories and sub-directories under it. I want to get the all the directories under Jobs and xcopy them to C:\backup. Then I want to xcopy all the files under each Job#1, 2 ,3 etc. to C:\backup\job#1\month\\*.* To make it clearer. Source dir = C:\Jobs\job#1\"myfiles&dir" Destination dir = C:\Backup\job#1\month\"myfiles&dir" then do the next folder Source dir = C:\Jobs\job#2\"myfiles&dir" Destination dir = C:\Backup\job#2\month\"myfiles&dir" ...until all folders are back-up. Since the job folder keep increasing, by doing it this way I don't have to add extra code on this script except modify the month. Thank you.

• How to verify the code that could take a substantial time to compile? [on hold]

  - by user18404

  As a follow up to my prev question: What is the best aproach for coding in a slow compilation environment To recap: I am stuck with a large software system with which a TDD ideology of "test often" does not work. And to make it even worse the features like pre-compiled headers/multi-threaded compilation/incremental linking, etc is not available to me - hence I think that the best way out would be to add the extensive logging into the system and to start "coding in large chunks", which I understand as code for a two-three hours first (as opposed to 15-20 mins in TDD) - thoroughly eyeball the code for a 15 minutes and only after all that do the compilation and run the tests. As I have been doing TDD for a quite a while, my code eyeballing / code verification skills got rusty (you don't really need this that much if you can quickly verify what you've done in 5 seconds by running a test or two) - so I am after a recommendations on how to learn these source code verification/error spotting skills again. I know I was able to do that easily some 5-10 years ago when I din't have much support from the compiler/unit testing tools I had until recently, thus there should be a way to get back to the basics.

• Excel chart: How to reverse the X axis of time series data

  - by JohnnyLambada

  In Excel 2003, I have a time series from a financial report that goes something like this: 2007 2006 2005 Amount 300 200 100 I want to create a graph of the time series that looks something like this (please excuse the ugly ascii graph): 300| .x | ... 200| .x.. | ... 100| x |____________________ 0 2005 2006 2007 But intead of getting an upward sloping graph, excel wants to put my time series in reverse (the way it actually appears in the spreadsheet). Is there any way to make excel display the x axis in reverse of the way it normally does? I've tried manually reversing the range in the chart dialog (changing a range of B1:D3 to D3:B1), but excel just puts it back.

• Bad Performance With Games Under Wine in Ubuntu 12.04

  - by Pandem

  I'm somewhat new to Linux. I've dabbled with it before but never more than just experimentation in a VM or dual boot where I almost always reverted back to Windows soon after (more due to a lack of commitment than a dislike for the OS). Anyway my problem is that in the two games (Guild Wars and Team Fortress 2) I've tried so far I get fairly bad performance. Despite both games having a "Platinum" rating I've still been forced to run both in DirectX 8, otherwise they either crash, have texture defects or the UI is missing. By "bad performance" I mean sub-30 FPS where there are some players and regular large framerate drops with video settings on low. Currently in my mind I believe the performance issues are just a problem with the drivers because my graphics card is a AMD 7850 which is virtually brand new and probably not properly supported yet but I'm unsure and would appreciate advice or tips to improve things. I have Ubuntu 12.04 installed and I am usually logged in a Gnome Classic session. I have installed AMD's proprietary drivers (Catalyst version 12.4) and have Wine 1.4 installed. I have used Winetricks to install DX9/DX10 dlls and other things.

• automatically change the gnome-terminal "title" for the window

  - by tom

  Hi. Trying to change the title of a current gnome-terminal (similar to the "set title" that you can do manually") The system is running Fedora 9. The HowTo Xterm-Title discusses how to set the prompt, for an xterm. Tried to implement the escape sequences with no luck. (might be something weird..) Tried to use the gconftool to dump/change/load the changed conf attributes, and again, no luck. Also, set the PROMPT_COMMAND just in case the prompt command was somehow changing the title back (which is highly doubtful) Searching the 'net indicates that a few people have tried to solve this with no luck... I'd also like to figure out how to create a new gnome-terminal with a unique specified title... once this is solved, i'l gladly create a quick writeup/post onn how to accomplish this for others... thanks

• Manually forcing TCP connection to retry

  - by Vi.

  I have a TCP connection (SSH session to some computer for example) Network suddenly goes down and drops all packets (disconnected cable, out of range). TCP resends packets again and again, retrying with increasing delays. I see the problem and plug the cable back (or restore network somehow). TCP connection finally successfully resends some packet and continues. The problem is that I need to wait for a some timeout on point 5. I want to use my opened SSH session now and not wait for 5-10 seconds until it finds out that connection is working again. How to force all TCP connections to resend data without delays in GNU/Linux?

• Data recovery after user profile corruption on Windows XP

  - by m68z8mi

  I'm away from home for college, and my computer back home has been having some issues. My dad took it to a computer store, and apparently the user profiles somehow got corrupted, so they're locked out of the computer. This is a Windows XP box, but I changed the default administrator account password, so that backdoor isn't a possibility. Now, that computer's HDD has a whole bunch of data on it which my dad would hate to lose, so I suggested that they take the HDD out, plug it into some other computer, and just copy all the data off that way (keeping in mind that the data itself wasn't encrypted). However, the computer store people said that wouldn't be possible unless they had the administrator account password (which I can't remember for the life of me), and that they'd either have to reformat and reinstall Windows, or else use some complicated sounding recovery process costing a decent amount of money. That sounds like complete BS to me, but I'm not 100% sure about it, so I thought I'd get some more opinions. Could someone more knowledgeable about this stuff suggest a good course of action to take?

• Stop Windows 7 from installing critical updates

  - by Rico

  I have disabled Windows Update on Windows 7, but it still downloads and installs critical updates. As with Windows XP, these updates occasionally create problems. But in XP, once I disabled automatic updates, the OS did not override my settings and continue to download and install critical updates. After the most recent critical update to Windows 7, every time I boot up, the USB devices connected to a single port through 4-way hub don't install. I have to unplug the hub from the computer then plug it back in. Then the devices install. I can use System Recovery to solve the immediate problem, but I'd like to disable automatic updates entirely. Why does Windows 7 not respect my settings like Windows XP did?

• Why is one specific file not showing up in my document library?

  - by Jay Bazuzi

  In my "Documents" library on Windows 7, one file is not showing up in Windows Explorer. When I look in C:\Users\%USERNAME%\Documents\blah\blah all 24 files appear. But when I look in Libraries > Documents > blah > blah only 23 show up. I made a copy of the file and the copy appears. Refresh doesn't help. The "Arrange by" setting defaults to "Name". When I change it to "Folder" the extra file appears, but changing it back to "Name" the file disappears again. How can I make the file appear in all views? Why would it disappear? EDIT: I deleted the Windows Search Index and things seem to be working again. I say it's a bug in the Search Service.
