  • How do you notice that the batteries of you wireless mouse are dying out?

    - by hkBattousai
    I have a Logitech M705 wireless mouse. I'm first time using a wireless mouse, so I don't have much experience with the hardware features and behavior. It is rated that it runs for 3 years with the same batteries. I think this "3 year" rating is calculated for a very low usage and activity; like 2 hours a day. I'm using it for about 12 hours a day, so I expect it to run out of batteries in a much shorter time in my case. I have been using it for about half a year. Recently (for the last two weeks), it started to make some peculiar behavior when clicking and drafging objects. - When I click something, it sometimes double click it. - When I drag something from one place to another (or selecting some text), it sometimes drops the object in the halfway (when selecting text, the text which had selected up to that time becomes unselected and it starts to select the rest of the text from that moment), but it goes on being in the "left-button-pressed" state. It is like, the pressed button switches to "unpressed" state for a moment, then returns back to the "pressed" state. When one of these faults occur, it occurs several times sequentially. There is no problem in pointer movement, scrolling or right-clicking. Since the batteries last for a very long time for this device, I don't expect it to stop working in an instance. I expect it to give these kind of syndromes of a time period. My question is; Is this how batteries run out for a wireless mouse? Or, is this another kind of hardware/software problem?

  • Unable to Use Bluetooth Mighty Mouse or Wireless Keyboard with Boot Camp

    - by Kristopher Johnson
    I have Windows 7 64-bit running on a MacBook Pro in a Boot Camp partition. I am trying to pair with my Bluetooth Mighty Mouse and Apple wireless keyboard under Windows, but whenever I try to do so, here's what happens: While on the Add a device window, I turn on the mouse or press a key on the keyboard, and the mouse or keyboard shows up in the list of available devices. I click the device and then the Next button, and the window displays Connecting to device... Time passes. Eventually, I get this error message: Adding this device to this computer failed Adding the device failed resulting in an unknown error. The reported error code is 0x80070015. Contact your device manufacturer for assistance. I've run Windows Update and Apple Software Update. I've also tried reinstalling the drivers from the Snow Leopard DVD. The mouse and keyboard both work fine when I boot into Mac OS X. FWIW, after many, many repeated tries, I eventually got it to work. I don't know why. So while my problem is solved, I'd still like to get an "answer" as to why trial-and-error seems to be the only approach. The keyboard, in particular, was hard to get set up. A few times, Windows would apparently recognize it and prompt me to enter the pairing code, but then it would time out after a couple of seconds (not long enough to enter the code). Grrrr.

  • What performance degradation to expect with Nginx over raw Gunicorn+Gevent?

    - by bouke
    I'm trying to get a very high performing webserver setup for handling long-polling, websockets etc. I have a VM running (Rackspace) with 1GB RAM / 4 cores. I've setup a very simple gunicorn 'hello world' application with (async) gevent workers. In front of gunicorn, I put Nginx with a simple proxy to Gunicorn. Using ab, Gunicorn spits out 7700 requests/sec, where Nginx only does a 5000 request/sec. Is such a performance degradation expected? Hello world: #!/usr/bin/env python def application(environ, start_response): start_response("200 OK", [("Content-type", "text/plain")]) return [ "Hello World!" ] Gunicorn: gunicorn -w8 -k gevent --keep-alive 60 application:application Nginx (stripped): user www-data; worker_processes 4; pid /var/run/nginx.pid; events { worker_connections 768; } http { sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; upstream app_server { server 127.0.0.1:8000 fail_timeout=0; } server { listen 8080 default; keepalive_timeout 5; root /home/app/app/static; location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://app_server; } } } Benchmark: (results: nginx TCP, nginx UNIX, gunicorn) ab -c 32 -n 12000 -k http://localhost:[8000|8080]/ Running gunicorn over a unix socket gives somewhat higher throughput (5500 r/s), but it still does't match raw gunicorn's performance.

  • How do I access my samba drive through several layers of network topology?

    - by stephenmm
    I have a new windows 7 Home Premium machine that is in a different room than my main computer area. As such I have to use a bridge and another router. Everything is working wonderfully except I cannot access the SAMBA drive with the new machine. I know that SAMBA is accessible as an older WinXP machine can access it. A picture of my network would probably be helpfull: To ISP | | +---------------------------+ | WAN | | Cable Modem | | (2WIRE678) | | | | | +---------------------------+ | +---------------------------+ | | (|) (|) +-----------+ | Belkin Router | | | | Wireless | | (F5D) |--+ +--| WinXP | | | |SAMBA USER | | | +-----------+ +---------------------------+ | | | | +------------+ | | Ubuntu | | | Apache + | | |SAMBA Server| | +------------+ | | +---------------------------+ | | | Netgear Bridge | | (XET1001) | | | +---------------------------+ # # +---------------------------+ | | | Netgear Bridge | | (XET1001) | | | +---------------------------+ | +---------------------------+ | | | D-Link Router | | (DI-524) | | | | | +---------------------------+ | | | | +-----------+ | | | Win7 | |SAMBA USER?| +-----------+ More interesting data points: 1. I can ping the SAMBA server from the Win7 machine locally (Ie. 192.168.2.2) 2. I can access the webserver from the Win7 machine locally (Ie. 192.168.2.2) 3. I followed the advice to get Win7 and SAMBA to play nice: http://www.tannerwilliamson.com/2009/09/windows-7-seven-network-file-sharing-fix-samba-smb/ Sorry for being so long winded but it is kind of complex and I am really at a loss as to how to fix it. If any of you have some suggestions I would love to hear it!

  • xauth, ssh and missing home directory

    - by flolo
    We have several servers, and normaly everything works fine, except now... we get a new aircondition installed. This takes 36 hours and for this time almost all servers got shutdown, only 2 remaining servers run for the most important tasks (i.e. accepting incoming email, delivering some important websites, login-server). Everybody was informed that when they need appropiate data from the homedirs they should fetch it before take down. Long story short: Someone realized that he have run a certain program on one of the servers. No Problem, he can remote login into our login server and run the programm there without home directory (binaries are local and necessary information can be copied to the /tmp). That works like a charm until... ... the user needs to run a GUI programm. I find no easy way to make it running, usually ssh -Y honk@loginserver is enough but now the homedirectory is missing and ssh is not able to copy the cookies into ~/.Xauthority (as the file server with the home directories is down). Paranoid as all systemadmins all X-Server just listen locally not on tcp ports, so no remote X connection possible SSH config is waterproof - i.e. no way to set environment variables. My Problem is, that the generated proxy MIT cookie from ssh get lost as the .Xauthority doesnt exist. If I could retrieve it somehow I could reenter it a .Xauthority in /tmp. The only other option (besides changing the config) which came to my mind is, makeing a tunnel (netcat, or better ssh) from the remote host to the loginserver and copy the cookie manually (not sure if it the tcp-unix domain socket stuff works as expected). Any good suggestions (for the future - now our servers are already up)?

  • Remote mouse pointer not visible in VNC

    - by aef
    I used VNC desktops as a kind of collaboration server, as shared planning and pair programming environment for a long time. Now my latest iteration uses a KVM guest running Fedora 17 "Beefy Miracle", the Cinnamon desktop environment and an X11VNC server. The X11VNC server is automatically started with the desktop environment using the following command: x11vnc -localhost -many -shared -display :0 -bg My problem is that depending on the VNC client, the mouse pointer of the remote system which is shown through VNC is not synchronized to my client. I really need this, so I can see what my partner is doing on the desktop. When using Vinagre 3.2.1 on Ubuntu Oneiric Ocelot (11.10) or Vinagre 2.3.0.3 on Debian Squeeze (6.0) and I don't have my local mouse pointer inside the VNC view, I cannot see the mouse pointer of my remote system, nor its movement. When using TightVNC on Windows 7, I can recognize a mouse pointer trace for very short amounts of time after moving the mouse, but it is not clearly visible. Using UltraVNC on Windows 7 the mouse pointer is clearly visible all the time. With Gnome 2 I never had any problems with remote pointer synchronization, using exactly the same clients. I suspect this could have something to do with Cinnamon's dependency on 3D acceleration. On the other hand, it doesn't change anything to start Cinnamon's fallback environment Cinnamon 2D. Update: Same effect when I use Gnome 3.

  • Extremely Weird Computer Problem

    - by waiwai933
    Well, having worked with computers a long time, I thought I had seen everything that could go wrong with a computer. Today, I learned that I was wrong. My Mac has been behaving extremely weirdly. While the keyboard is fine, the mouse holds extremely weird behavior. It will open apps from the Dock, but not open documents from a Stack. The top menu bar will work, but only after I restart Finder. I am unable to close most windows, except with Cmd+Q. Clicking on a link in Safari, for some reason, opens it in a new tab. I can not select checkboxes, but I know a click is going through because you can see a quick indent in the check box, before it reverts to the unchecked state. I've restarted my computer, as well. I don't see a virus when looking through top, but I guess it could be subverting top. Does anyone have an idea what is going on?

  • Ubuntu 12.04 open port 80 inside WLAN

    - by Eduard
    I have an nginx server running on ubuntu 12.04 that serves http through port 80 and https through port 443. Everything works fine if I access it from the same computer via localhost, 127.0.0.1 or the local IP 192.168.0.11. If I try to access the server from another computer in the same VLAN it does not work for http; it works for https. I have changed my nginx configuration to also listen to port 8000 for http; I can then access http from the other computer in the same VLAN via "http://192.168.0.11:8000". I also have a web server running on port 80 on a windows machine and can access it from another device in the same VLAN, therefore the router is not blocking incoming http traffic. The nginx process is run by root. I have used tcpdump and I see that packets are arriving to Ubuntu: 192.168.0.16.49735 192.168.0.11.80 and that some response is being given 192.168.0.11.80 192.168.0.16.49735 (I do not know what the response is though). There is no request arriving at the nginx web server (I have checked the access log). I have iptables empty. I have unsuccessfully tried to find a solution for a long time to this, it has now become a matter of happiness or bitterness :).

  • Index a low-cost NAS on Windows 7

    - by JcMaco
    Has anyone found a way to index the files stored on a Networked Attached Storage on Windows 7 so that the files can be available in Windows Search and Libraries? I am referring to the cheap and available NAS like the Western Digital My Book series that use an embedded linux server. Similar question: http://windows7forums.com/windows-7-networking/6700-indexing-nas-drive-libraries.html EDIT Windows help proposes to make the files stored on the NAS available offline. This is obviously not a good solution if the NAS has more data than what the client can store. If the folder is on a network device that is not part of your homegroup, it can be included as long as the content of the folder is indexed. If the folder is already indexed on the device where it is stored, you should be able to include it directly in the library. If the network folder is not indexed, an easy way to index it is to make the folder available offline. This will create offline versions of the files in the folder, and add these files to the index on your computer. Once you make a folder available offline, you can include it in a library. When you make a network folder available offline, copies of all the files in that folder will be stored on your computer's hard disk. Take this into consideration if the network folder contains a large number of files.

  • Games, Windows 8.1 and 144Hz display

    - by Marioysikax
    So I have been having problems with few games after switching from 7 to 8.1, which seems to be related to my 144Hz monitor. Few examples: Shank, Shank 2, Blood of the Werewolf, Astebreed, the Sims 2 and Rayman Legends patch 1.2Had few other as well but it's been long and I have 600+ steam library. From those games at least the Sims 2 and Shank worked without any problems with same setup and Windows 7. So basically these games simply refuse to launch with basic setup. However if I plug 60Hz TV with HDMI instead everything magically starts to work. As for Astebreed and the Sims 2 using windowed mode seems to also work. As for Rayman Demo and version 1.0 works for some reason and 1.2 breaks settings menu. I have already tried contacting supports. EA support stated game simply shouldn't work with 8.1 at all (which is lie as it works with that TV and friend with 8 plays just fine), ubisoft support took few weeks and support said he will forward info for further processing, blood of the werewolf support had no idea what's going on and told me to just use my TV instead.Changing monitors refresh rate to 120Hz or forcing it to 60Hz doesn't do anything. I have DVI right now but I will try with DisplayPort when I get the cable. At PCGW Garrett said it may have something to do how listing resolutions work with 8 compared to earlier Windows versions but my googling skills don't bring anything up and compatibility mode for earlier windows version doesn't work either (not that I expected that to work). My system specs are on my steam profile. How do I get those work with my 144Hz monitor as well as possible future games having same problem? Downgrading to 7 would work but is far from practical and I don't own legit lisence for that one.

  • Struggling with proper way to setup Permissions on Linux/Apache Web Server

    - by Dr. DOT
    Your expert experience and assistance is great, greatly appreciated here. I have been running a LAMP server for a long time, yet I still struggle with the best way to set file & directory permissions for FTP and WWW protocol activity. My Control panel is WHM/cPanel (not that it makes a difference), and out-of-the box: files are owned by the user account setup in WHM (eg, "abc") files have a group setting of "abc" as well file permissions are created with 644 directories are owned by "abc" directories have a group setting of "abc" directories permissions are created with 0755 Again, these are the default permission settings. Now everything is fine with FTP activity, but please advise me if any of these file/directory settings create issues, especially with security. Here's where my struggle comes into play. I have PHP apps that allow a visitor to create, edit, rename, delete, etc. sub-directories and files in certain selected directories. PHP runs as "nobody" on my server. So in order to get my PHP/Web apps to work, I have had to: chown nobody * chgrp nobody * chmod 0777 * to everything in these certain & selected sub-directories. I know this is probably a huge security whole (so don't ask me for any links :) but how should I set all the permissions to allow my FTP user to do his thing while allowing the PHP apps to do their thing will also "minimizing" any security risks and exposures? I know that big CMS systems like Drupal, Joomla, WordPress and so on, handle this. Thanks ahead of time for reading through this and offering your expert advice!

  • RD Gateway reporting features/capabilities

    - by Don
    We have just implemented RD Gateway for our own department in preparation for a push to the whole agency for telecommuting. It is all setup and working great, but I was trying to figure out how best to go about monitoring/reporting of users. I see third party software out there that will do it, but is there anything built-in or via powershell/scripting that I could use that would give me a report of the daily activity of users? Something to say, "User A connected at this time, was on for this long, sent/received this much data"? Basically some of the same stuff you can see in event viewer. Ideally I'd like to be able to have this setup so that once a day it emails me with the daily usage for when a supervisor asks about if their person is actually working (or at least online sending and receiving x amount of data), I'll have some metrics to give them. I realize that actual work output is relevant and more of a managerial issue, but I would like to be able to offer as much as I can from my end when asked. Thoughts? Thanks!

  • Why does my PC successfully boot only when unplugged for more than a few minutes?

    - by philg
    I have an HP Pavilion Elite desktop computer, model HPE-490t. I like it because it didn’t cost too much, boots itself from an SSD, came with 16 GB of RAM, and has 6 CPU cores for editing video and camera RAW images. It has one behavioral quirk that I cannot explain, however. The recent power interruptions here in the Northeast got the machine into a state where it could not be restarted. It would power up for a second or two, shut down, and then power up again, never being able to get to the point of showing anything on the monitor. I unplugged it for about 10 seconds and plugged it back in. Same behavior (fails to boot). I unplugged it and walked away for an hour, then plugged it back in and it worked perfectly! I think something similar happened after installing a second hard disk drive into this machine. So the question is why does the computer behave differently depending on how long it has been unplugged? Where is energy stored that affects the machine’s ability to boot? Capacitors in the power supply? Battery on the motherboard (there is one for the clock, but that wouldn’t be exhausted by being unplugged for an hour, I don’t think)?

  • Arch Linux: eth0 no carrier - network fails at boot

    - by user905686
    The problem My computer is connected to a network where dhcp is required. So my network configuration in /etc/rc.conf looks like interface=eth0 address= netmask= broadcast= gateway= My deamons are DAEMONS=(!hwclock syslog-ng network netfs crond ntpd) With this configuration, Arch hangs at boot a long time at "Network" (Still it says "[done]", but after boot I have no connection). I found out two workaround: Workaround 1 remove network from deamons run mii-tool --reset eth0 and dhcpcd eth0 after boot (somehow it does not work when placing these commands in /etc/rc.local. Then dhcp work very quickly (because of the reset!). Before executing the first command, ip link show eth0 has "NO CARRIER" in output. Afterwards, it doesn´t. (Also, mii-tool first shows "no link", afterwards eth0: 10 Mbit, half duplex, link ok. Workaround 2 Change network configuration to interface=eth0 address=x.y.z.21 netmask=255.255.255.0 broadcast=xxx.y.z.255 gateway=x.y.z.254 whereas x, y, z build the specific adresses of the network (Though dhcp is used, I get a static ip). Add the commands mii-tool --reset eth0 and dhcpcd eth0 to /etc/rc.local Now network starts quickly at boot (though I don´t know if successfully), the commands in /etc/rc.local are executed and the connection is fine after login. What to do? So the problem seems to be that dhcpcd stucks at "wating for carrier" or sth. I do not like the workaround, because some deamons need network (though they seem to start). What can I do to have eth0 ready for dhcp at boot? Or is there another problem?

  • IIS7 default document for urlMapped url throws 403 error

    - by MorningZ
    Hopefully this all makes sense: I have a Web Application project against an IIS7 server that is "theme-able" using different master pages. As a result of what I am trying to do, the root of the project has no aspx files, so I am using the web.config's ability to rewrite "~/default.aspx" to "~/themes/a/default.aspx" this works great as long as i type in "http://www.mysite.com/default.aspx", but typing just "http://www.mysite.com" results in a "403 - Forbidden: Access is denied" error I was hoping that the combination of urlMapping and default document would be smart enough to handle this, but it's not <system.webServer> <defaultDocument enabled="true"> <files> <clear /> <add value="default.aspx"/> </files> </defaultDocument> </system.webServer> i also tried <system.webServer> <defaultDocument enabled="true"> <files> <clear /> <add value="~/themes/a/default.aspx"/> </files> </defaultDocument> </system.webServer> to no avail I was hoping a browser would come in without a document defined, IIS7 would assume it was default.aspx, and then the urlMapping would map it accordingly, but nope any pointers? I've read a ton of posts here with similar issues, but not the exact issue

  • DDoS nulling to some ips and other options?

    - by Prix
    I am looking for some information in regards DDoS in the follow scenario: I have a server that is behind a Cisco Guard and it will be DDoS'ed, I only care about a set list of IPS that by not means are the attackers. Is it possible to null all other ips but this list to actually get any response to my server or in the long run no matter what I do if they have enough DDoS power I will just go down like a flie ? Is there any recommended company out there that can actually cope with a DDoS ? My server will mainly run several clients that will get connected to a external server and all it needs access to is my local MySQL the the private network so I can access it. There will be no other services runnings such as web or ftp etc at least not to the external ips of the server if i ever have to have any of these service they will be on the private network. The MySQL will be available externally only to 1 safe ip not known by anyone but me and internally at localhost + private network. Are there any solutions ?

  • Performance data collection for short-running, ephemeral servers

    - by ErikA
    We're building a medical image processing software stack, currently hosted on various AWS resources. As part of this application, we have a handful of long-running servers (database, load balancers, web application, etc.). Collecting performance data on those servers is quite simple - my go-to- recipe of Nagios (for monitoring/notifications) and Munin (for collection of performance data and displaying trends) will work just fine. However - as part of this application, we are constantly starting up and terminating compute instances on EC2. In typical usage, these compute instances start up, configure themselves, receive a job from a message queue, and then get to work processing that job, which takes anywhere from 15 minutes to over 8 hours. After job completion, these instances get terminated, never to be heard from again. What is a decent strategy for collecting performance data on these short-lived instances? I don't necessarily need monitoring on them - if they fail for whatever reason, our application will detect this and handle re-starting the job on another instance or raising the flag so an administrator can take a look at things. However, it still would be useful to collect information like CPU (user, idle, iowait, etc.), memory usage, network traffic, disk read/write data, etc. In our internal database, we track the instance ID of the machine that runs each job, and it would be quite helpful to be able to look up performance data for a specific instance ID for troubleshooting and profiling. Munin doesn't seem like a great candidate, as it requires maintaining a list of munin nodes in a text file - far from ideal for an environment with a high amount of churn, and for the short amount of time each node will be running, I'd rather keep the full-resolution data indefinitely than have RRD water down the data over time. In the end, my guess is that this will require a monitoring engine that: uses a database (MySQL, SQLite, etc.) for configuration and data storage exposes an API for adding/removing hosts and services Are there other things I should be thinking about when evaluating options? Perhaps I'm over-thinking this, though, and just ought to run sar at 1-minute intervals on these short-lived instances and collect the sar db files prior to termination.

  • Sudden and frequent hangs on desktop computer: mobo or CPU fault?

    - by djechelon
    I have a desktop computer equipped with an ASUS Crosshair 2 Formula and a Phenom x6 3.2GHz CPU. My problem is that often the computer will hang all of a sudden, completely stopping responding. When that occurs, reset key is inoperative and power button turns the computer off but is unable to turn it back on. I have to physically disconnect power cable. The problem can occur anytime, when I'm booting Windows, when I'm logging in, when I'm listening to a song, when I'm browsing Internet, etc. It always occurs after very few minutes of 3D gameplay I thought it was a video card fault. I had 3 8800GTX so I could try all combinations of them: didn't fix I thought it was a RAM problem: I tried running with only a subset of my DDR2 banks but didn't fix. Almost every time I have to reset and reconfigure BIOS (without AHCI, Win7 won't boot, so I need to restore a few things). If I enable AMD Live, Cool&Quiet or other things from CPU configuration menu I'll be sure that the computer won't reach Windows desktop in 99% of cases (it randomly hangs somewhere in the boot process or even in the BIOS POST). Another interesting thing is that during the POST process the computer always takes unusually long time detecting USB devices (LCD POSTer shows USB INIT), and I've also tried disconnecting all USB devices but didn't take less time to POST BIOS revision is 2702, the latest. Today I found a different behaviour once: during boot screen I got a BSOD with error Stop 0x00000101 A clock interrupt was not received on a secondary processor within the allocated time interval, and this is usually related to overclocking, but I never overclocked my CPU. Judging from the description of my problem, hoping someone had the same and fixed, and since I don't have a spare CPU or motherboard for replacement, I'd like to ask if you think this is a problem with faulty CPU or faulty motherboard, and if I can perform additional tests (I mean software tests because of my lack of spare components) to identify the component to replace.

  • Hard Drive that was used before not detected or accessible in Windows 7

    - by Anders
    Hello SU: My PC crashed for some unknown reason, and I am still working on what caused that. However, I pulled my main (windows) drive from my computer and hooked it up to my roommate's machine and was able to pull the data I needed off of it (i.e. the drive is good). I hook up his drives as they were, I had to turn off his machine and unplug his secondary drive to hook mine up, boot his machine and there is no second drive available in windows explorer. I opened Device Manager to see if for some reason it's drive letter got un-assigned, but there is nothing listed in there except his primary hard drive, his optical drive and one other optical drive which I believe is the virtual drive Daemon Tools made. The drive shows up in the BIOS, however after I restarted his machine again it sits on the "Entering setup....." screen at the load window. The only thing I can think of is that may have messed with stuff is I used this tutorial to create a bootable XP install on a USB drive to install XP on my machine (I am 99% certain that the optical drive in my PC is broken) and maybe it used the other hard drive's letter for the USB drive for some reason, which doesn't make much sense since it was recognized it as a different drive letter before I started the process. It is possible that it used the secondary hard drive's letter for it's work, but once again I am uncertain. Where should I go from here? He his bound to wake up within the next several hours and will probably flip a lid if I cannot get some sort of handle on this. Any and all help is greatly appreciated. PS: Anyone who helps me get this situated has a beer or two on me, as long as you are in the greater metro Detroit area, or don't mind traveling a bit!

  • Reliable custom Windows shortcut keys?

    - by Peter Baer
    I have global Windows shortcut keys assigned to several different cmd.exe instances. I do this by creating shortcuts to cmd.exe on my desktop, and assigning each one a unique shortcut key (for example, CTRL + SHIFT + U). Pretty basic stuff. I'm using Win2K8 (R1 and R2). This works just fine... most of the time. But with infuriating regularity, sometimes it doesn't. Or it will work with a long delay (many seconds). It doesn't matter what app currently has focus (it can even be one of the command prompts). It doesn't matter what keys I assign (I've tried a few variations of WIN, CTRL and SHIFT). I did notice that this is often, but not always, correlated with explorer.exe struggling in some way or another (say, an explorer window opened to a file share that's unavailable, or an app being unresponsive, or whatever). In other words the shortcut key handling appears to be very sensitive to unrelated system activity. Note that whenever I have this problem I can always successfully ALT + TAB to the window I want to get to, but that's tedious. I use the shortcuts to these command windows hundreds of times a day so even a 1% failure rate becomes really annoying. Is there a way to fix this, or is there some third-party utility out there that will RELIABLY intercept custom key combinations to bring focus to whatever apps I want, in a way that is independent of other system activity? ADDENDUM: There is a property of the Windows shortcuts that I would not want to lose if switching to a third-party hotkey tool: Windows shortcuts are idempotent. Once you've launched a shortcut to some app, pressing the shortcut key combo again takes you to the already launched process - it does not launch a new process.

  • How to get data from a borked Windows Home Server

    - by harhoo
    Yesterday we had a power surge, followed by a power outage. This left my WHS borked: powering on just gives to a flashing blue light (the led on the power supply also flashes green) - no fan or boot activity, nothing. I urgently needed some files off there in the short term (and the 500GB of photos, music, personal video etc in the long term) so I took the hard drive out and put it in my computer. The files and folders showed up, but I couldn't access them - clicking on an image gave an invalid image error in Picasa, I couldn't play MP3s etc. I changed the ownership and permissions of the files, still nothing. I booted in with a LiveCD, the same: files appear, but won't open. Is there anything else I can do? I'm now wondering if it was just the power cable that's broken, but if so, why can;t I access my files from the hard drive? If it is the power cable, and I replace that and the hard drive, will I have done any harm messing around with ownership and file permissions?

  • Finding matching columns in excel

    - by fakaff
    I've never used excel before so I need the simplest solution available, and this is a work assignment due this week so I didn't have time read much of the documentation. Basically, I have two tables, A and B, and they are both thousands of rows long. Description of my task: right now (since I don't know better) I'm manually doing this: Go to row i in table B. Select entries in columns B(a, b, c) of that same row. Look for a row in table A where column A(b) matches row B(a). Paste the entries of columns B(a) of row i at the end of the row found in the last step. Repeat for row i + 1. Example: row B(cat, dog, mouse) matches A(mammal, cat, Mr. Whiskers). So I would paste B after A and have A(mammal, cat, Mr. Whiskers, cat, dog, mouse). Note: I am not joining tables. I am merely extending table A by pasting row A(b) if row A(b) matches row B(a). Also, sometimes entries are spelled slightly differently. Using wildcards to search for candidates would be of help. As the description should let on, this task is very tedious and inefficient if I don't know how to automate some operations (there are thousands of entries). Any quick tips as to how to be more productive is a big help.

  • RDP Connection to Windows 7 stays really slow

    - by Pavlo
    I have an Issue with connecting to Windows 7 via RDP. I can open an RDP Session, but regardless of any settings, the responce times are really long. This in particulary is the case when opening a web page in a browser. I've tried IE, Firefox and Google Chrome. I also use RDP connection to a Windows 2008 Server from the same client machine, and the speed is very normal with all features turned on. We have Gigabit Ethernet here. So I think it can not be the client's fault. What concerns Windows 7 Machine, I've tried shutting all the sraphic features off and turning the color levels to 256 colors. Result - the same. If I work locally on the machine - I can not see any lags. What else have I tried: Using old RDP 5 Client from Microsoft Setting network autotuninglevel as seen here Do You have some ideas? Thanks in advance! Update the problem seems to be with rendering window contents. All the window borders and pannes are rendered pretty quickly, but the content shows up very slowly. Also mouse movements are recognised by the Win 7 box only after some period. Are there some hidden settings in the RDP, where one could turn some advanced features off or turn some caching on? I use Bitmap Caching, but this apparently doesn't help.

  • Virtualization in Ubuntu 9.10

    - by Jeff Dege
    I have an existing Centos 5 installation. I would like to upgrade to Ubuntu. Thing is, I don't want to be down for as long as it will take to get my entire environment moved over - software installed, connectivity configured, etc. I'd like to take it one step at a time. But I don't really want to keep rebooting back and forth from the new OS to the old OS. That's what I did last time I upgraded to a new OS, and it got old real fast. So, since my new MB is virtualization-ready (AMD Phenom II 945 quad-core), I figured I could create a virtual machine, under the new OS installation, that ran the old OS installation. The problem is that the documentation I've been able to find has been pretty sparse. I've found a lot of possibilities, and little info on which would be capable of doing what I want. I have a new Ubuntu 9.10 installation, and a second disk containing the Centos 5 installation. And I don't know where to go next. Any help would be appreciated.

  • ESXi 5 VM Putty session hangs, vSphere client timing out

    - by user192702
    First of all I believe this is a ESXi issue but let me know if you have seen this. It started about a year ago when I noticed occasionally when I putty via SSH to my VM guests, if I do anything that makes it to display a lot of things at once, the session will hang and I have to start a new one quite often only to find the same behaviour. What I meant by display a lot of things can be any of the following: 1) tail -f filename 2) Paste a long command 3) less filename If I type in one character at a time this won't happen. I tried searching online and it always point me to flow control settings and the various suggestions I've tried have never been able to resolve the issue. Since last week, I've noticed I'm not able to connect to my POP3 server from Outlook (it's timing out from Outlook's perspective). Today I tried to connect to the ESXi via vSphere client and it gives me a time out also. Exact behavior and error I saw is similar to the one posted at the following URL but the suggested technique also failed to resolve the issue. http://davidcocke.blogspot.hk/2012/02/unable-to-login-with-vsphere-client.html Has anyone experienced this before? Any suggestions on how to troubleshoot this?
