  • Dell Docking Station Doesn’t Detect USB Mouse and Keyboard

    - by Ben Griswold
    I’ve found myself in this situation with multiple Dell docking stations and multiple Dell laptops running various Windows operating systems.  I don’t know why the docking station stops recognizing my USB mouse and keyboard – it just does.  It’s black magic.  The last time around I just starting plugging the mouse and keyboard into the docked laptop directly and went about my business (as if I wasn’t completing missing out on a couple of the core benefits of using a docking station.)  I guess that’s what happens when you forget how you got yourself out of the mess the last time around.  I had been in this half-assed state for a couple of weeks now, but a coworker fortunately got themselves in and out of the same pickle this morning.  Procrastinate long enough and the solution will just come to you, right? Here’s how to get yourself out of this mess: Undock your computer Unplug your docking station Count to an arbitrary number greater than 12.  (Not sure this is really required, but…) Plug your docking station back in Redock your machine I put my machine to sleep before taking the aforementioned actions.  My coworker completely shutdown his laptop instead.  The steps worked on both of our Win 7 machines this morning and, who knows, it might just work for you too.

  • pfsense multi-site VPN VOIP deployment

    - by sysconfig
    have main office pfsense firewall configured like this: local networks WAN - internet LAN - local network VOIP - IP phones need to connect remote offices (multi-users) and single remote users (from home) use IPSEC or OpenVPN to build "permanent" automatically connecting tunnels from remote location to main location. in remote locations, network will look like this: WAN - internet LAN - local network multiple users VOIP - multiple IP phones in order for the IP phones to work they have to be able to "see" the VOIP network and the VOIP server back at the main office for single remote users ( like from home ) the setup will be similar but only one phone and one computer so questions: best way to tie networks together? IPSEC or OpenVPN can this be setup to automatically connect ? any issues/suggestions with that design/topology ? QoS or issues with running the VOIP traffic over a VPN throughput, quality etc.. obviously depends on remote locations connection to some degree

  • SQL SERVER – Download SQL Server Product Documentation

    - by pinaldave
    Today I just returned from Bangalore User Group Meeting. Attending User Group meeting is indeed fun and really great experience. The best part of the User Group is meeting like minded people and have a great conversation with them. During the meeting I was asked why one has to go online to access SQL Server Product Documentation. I can clearly see there can be many reasons for why one wants the documentation to be available offline. The reasons can be anything but not limited to Company Firewall No Internet (power failure, on road or disaster) Internet Bandwidth Limitatoin Company Proxy Issues … and much more… In this kind of situation one needs documentation which is offline and easily available in local computer. The Microsoft SQL Server 2012 setup installs only the Help Viewer and related components for managing Help settings. Setup does not directly install any documentation. All of the SQL Server documentation is available online. Well, Microsoft has recently released Production Documentation available for offline users as well. You just have to download the executable file and follow all the instructions. Please follow the link below for download of the file. There is detailed instruction on how to download and install the documentation offline.

  • How to connect 3 monitors into an Asus 9800GT

    - by aliasbody
    I don't know if this is possible but, I've heard that there exist some DVI connections that allow and recognize the connection os 2 Monitores in the same port (I can be wrong tho). I have an Asus 9800GT 512MB on my computer that runs Ubuntu 12.04 and Arch Linux, and I am trying to connect 3 monitors. I already have 2 (17" each), and want to connect a new one with 19", but on my 9800GT I only have 2 DVI connections. Is there anyway to have 3 monitores extended without having to buy a new GPU ? Thanks in Advance,

  • How do I see what connections are being made?

    - by Coldblackice
    My DDWRT router is showing that my computer has a connection count around 600! The router is at 100% CPU use. How can I see what's making all the connections? So far, I've opened up Resource Monitor and checked the network tab. I can sort by which program is using the most network bandwidth (Pale Moon browser), but I can't see what's making all of the connections. Or rather, where all the connections are being toward (trying to find what tab must be making all of these connections). I've also tried netstat -A, but it apparently doesn't show the actual number of connections being made. At least, the list of established connections isn't very long, by any means (like enough to account for the 500+ connections apparently being made.

  • ffmpeg, vlc - Unable to find input stream

    - by zozo
    Good day to all... I have some "little" problems with ffserver and ffmpeg... What I need to do is to broadcast a live video. So I got the cam... used vlc and used send stream option. I sent it to 192.168.1.9:64555, which is a virtual machine on the same computer, running centos. On the virtual machine I run the command ffmpeg -i 192.168.1.9:64555 output.mpg. The response is "unable to find file whatever". Can any1 tell me what I did wrong? Thank you and have a great day. Print-screen with error:

  • XFCE: active panel buttons when mouse is on screen edge

    - by Dave Vogt
    I'm using XFCE 4.6.1 (Xubuntu distribution) on my laptop and main computer; the settings are approximately the same. so far for the intro. What I'm experiencing is that when going to the screen edge over the task bar on the laptop, the button under the mouse is active. On the main machine however, having the mouse on the screen edge, the button below it doesn't react at all! Only if I move the pointer towards the center a bit, the hover highlight starts and the button becomes clickable. I've tried to change the panel size, desktop theme and a few other settings, but none seems to cure that problem. Is there something that causes this problem? (Googling also seems to give no results)

  • Trouble with setting up Mac SSH with TP-LINK router

    - by arxanas
    I have a Mac running OS X 10.7.2, and a TP-Link TL-WR740N (whose control panel looks like this). Remote Login is on in the Mac's System Preferences, and port 22 is set to forward on the router. I can access my Mac as a web server using the external IP on port 80, which I have set up through the same port-forwarding mechanism provided by the router, but when I try to ssh server@external-ip, it just times out after a long while. (The same thing happens when I try vnc.) I can, however, ssh and vnc successfully into that computer while I'm on the same network when using its internal IP. Since ssh appears to work and port forwarding appears to work, I can't figure out what's causing the problem. Does anyone have any idea what might cause this?

  • Line Numbering in Notepad-Week 41

    - by OWScott
    You can find this week’s video here. Notepad is so simple, yet so useful. Yet, at times the "Go To" appears to break and doesn't work as expected. This week's video is short and sweet. Learn about line numbering in notepad. One of my all-time favorite applications is notepad. You may think I’m joking, but I’ve grown quite fond of notepad over the years. Like a faithful friend, always there for you when you need it. Whether it’s an old computer or new, it opens instantly. I can’t remember notepad ever crashing. Wish I could say that for most other applications. This week’s lesson is a quick one, but if you’ve ever run into issues with line numbering in notepad, I hope you find it useful. I remember the first time the “Go To” feature didn’t work in notepad for me. It took me a while to figure it out so I hope to save you the grief that I went through. Watch this week’s video for a couple quick tips on the tried and true notepad. This is now week 41 of a 52 week series for the web pro. You can view past and future weeks here: http://dotnetslackers.com/projects/LearnIIS7/ You can find this week’s video here.

  • Command-line access to remote MySQL server

    - by Jerry Krinock
    I administer a website on a remote, shared host. My web host offers MySQL, and I am able to access this from my Mac OS X computer using a GUI program, Sequel Pro. That works great. But I want to script some queries, and Sequel Pro is not scriptable. What should I do? I've read about tunneling to mysql via SSH. I have shell access to the server, with an SSH key on my Mac, so ssh [email protected] -p 7978 gets me in. Should tunneling the MySQL port 3306 work? Like this? ssh [email protected] -L 3306:127.0.0.1:3306 (It "times out" after a minute.) Do I need to install mysql on my Mac?

  • What is the definition of "Big Data"?

    - by Ben
    Is there one? All the definitions I can find describe the size, complexity / variety or velocity of the data. Wikipedia's definition is the only one I've found with an actual number Big data sizes are a constantly moving target, as of 2012 ranging from a few dozen terabytes to many petabytes of data in a single data set. However, this seemingly contradicts the MIKE2.0 definition, referenced in the next paragraph, which indicates that "big" data can be small and that 100,000 sensors on an aircraft creating only 3GB of data could be considered big. IBM despite saying that: Big data is more simply than a matter of size. have emphasised size in their definition. O'Reilly has stressed "volume, velocity and variety" as well. Though explained well, and in more depth, the definition seems to be a re-hash of the others - or vice-versa of course. I think that a Computer Weekly article title sums up a number of articles fairly well "What is big data and how can it be used to gain competitive advantage". But ZDNet wins with the following from 2012: “Big Data” is a catch phrase that has been bubbling up from the high performance computing niche of the IT market... If one sits through the presentations from ten suppliers of technology, fifteen or so different definitions are likely to come forward. Each definition, of course, tends to support the need for that supplier’s products and services. Imagine that. Basically "big data" is "big" in some way shape or form. What is "big"? Is it quantifiable at the current time? If "big" is unquantifiable is there a definition that does not rely solely on generalities?

  • Motherboard on, but nothing will start

    - by Geeklat
    I'll try and be as clear as possible. Recently I purchased a barebones kit for my first attempt at a full PC assembly. I've gone through and connected all the parts correctly based on numerous examples that confirm everything is connected correctly. The motherboard and the video card are receiving power based on the fact that the motherboard's power LED is on and the video card has some LEDs on. Nothing else in the computer will come on when pressing the power button on the case. No fans, no hard drive, no CPU fan. Not even for a split second. I also receive no beeping noise from the speaker connected to the motherboard. I've also tried swapping the reset and power connectors from the front of the case to no luck.

  • dpkg E: Sub-process /usr/bin/dpkg returned an error

    - by user81269
    I decided to shift around my partitions on my hard drive for a fresh install of Kubuntu. I booted my Ubuntu 10.10 live disc, shifted everything around and attempted to install grub and it didn't work, so I burnt an Ubuntu 12.04 disc and installed it. I got the computer working and wanted to install some packages, but didn't have an internet connection at the time. So (I know this was stupid) I got some debs from previous versions of Ubuntu, as I needed my music, and the other install took a long of time to boot. Once I got my internet connection back, everything worked ok, for a little while. Then I stumbled upon this problem after removing ten broken packages using synaptic: drhax@Spamotard:~$ sudo apt-get install -f Reading package lists... Done Building dependency tree Reading state information... Done The following packages will be REMOVED: libgtk2.0-cil 0 upgraded, 0 newly installed, 1 to remove and 417 not upgraded. 1 not fully installed or removed.

  • Daylight Saving Time Visualized

    - by Jason Fitzpatrick
    When you map out the Daylight Saving Time adjusted sunrise and sunset times over the course of the year, an interesting pattern emerges. Chart designer Germanium writes: I tried to come up with the reason for the daylight saving time change by just looking at the data for sunset and sunrise times. The figure represents sunset and sunrise times thought the year. It shows that the daylight saving time change marked by the lines (DLS) is keeping the sunrise time pretty much constant throughout the whole year, while making the sunset time change a lot. The spread of sunrise times as measured by the standard deviation is 42 minutes, which means that the sunrise time changes within that range the whole year, while the standard deviation for the sunset times is 1:30 hours. Whatever the argument for doing this is, it’s pretty clear that reason is to keep the sunrise time constant. You can read more about the controversial history of Daylight Saving Time here.

  • Can I upgrade my Soltek sl-67a-c motherboard from Pentium II to Pentium III?

    - by jedatu
    I have a Pentium III processor and I thought I would replace the Pentium II on my Soltek SL-67A-C. The motherboard has Slot 1 so the PIII fits in fine, however, when I turn on the computer the bios does not come up. Here's the link to some specs on the board: http://stason.org/TULARC/pc/motherboards/F/FLASH-TECH-INC-Pentium-II-Deschutes-SL-67A-C.html I know that I updated the bios at one time. I see references to a "67af3.zip" bios upgrade file out there but can't find any source to download it. I am thinking I may have to adjust the jumpers on the motherboard to match the speed of the processor, but I am not sure how to go about that. Any suggestions?

  • Lack of Virtual Memory - confusion

    - by Wesley
    Specs ahead of time: AMD Athlon XP 2400+ @ 2.00 GHz / 1 GB PC-3200 DDR RAM / 160 GB IDE HDD / 128 MB GeForce 6200 AGP / FIC AM37 / 350W PSU / Windows XP Pro SP3 So, XP has pop-ups saying that I am low on virtual memory. However, I have a program called SmartRAM (part of Advanced SystemCare by IObit) and it displays CPU & Page File Usage and Free Physical and Virtual Memory. That program shows that I have at least 2000 MB free virtual memory on my machine when the XP pop-ups say that I'm low on virtual memory. First off, would a complete lack of virtual memory cause my computer to freeze? Secondly, how can I solve this lack of virtual memory? (A complete reformat is possible but can't be done immediately...) Thanks in advance.

  • graphics-card makes sound-card produce a buzzing sound

    - by Markus von Broady
    Recently I bought a new GPU: GeForce GTX 550 Ti, and after installing it I get a strange buzzing sound. It's not always there, just sometimes (mostly when I open some game, but sometimes also in browsers etc.). It's not a capacitor or a fan, as unplugging speakers from sound-card makes the 'bzzzzzzz' go away. However, muting windows doesn't mute this sound. I'm pretty sure it is fault of the new GPU, but how is this happening and can I fix it? Can it be a low power supply? I thought of buying a stronger unit, but as everything works, and computer doesn't shut down, I hesitate.

  • Running hardware with only 32bit drivers in 64bit windows

    - by Howard
    Recently we had to upgrade a system to handle added HD IP cameras. This upgrade involved an entirely new computer build with the exception of a rather pricey Geovision DVR (PCI/GV1480 series). Apparently while these cards do support Windows 7, they do not support Windows 7 x64. I'm stuck between a rock and a hard place here trying to figure out how we can remedy this, is there a virtualization solution that will allow devices with driver issues to passthru to the Guest OS? I was thinking XPMode may work for this solution however I am unsure if it runs 32bit or 64bit and if it'll allow driver-issue devices to pass to it. Any help would be greatly appreciated, Best Regards, Howard

  • Declarative programming vs. Imperative programming

    - by EpsilonVector
    I feel very comfortable with Imperative programming. I never have trouble expressing algorithmically what I want the computer to do once I figured out what is it that I want it to do. But when it comes to languages like SQL or Relational Algebra I often get stuck because my head is too used to Imperative programming. For example, suppose you have the relations band(bandName, bandCountry), venue(venueName, venueCountry), plays(bandName, venueName), and I want to write a query that says: all venueNames such that for every bandCountry there's a band from that country that plays in venue of that name. In my mind I immediately go "for each venueName iterate over all the bandCountries and for each bandCountry get the list of bands that come from it. If none of them play in venueName, go to next venueName. Else, at the end of the bandCountries iteration add venueName to the set of good venueNames". ...but you can't talk like that in SQL and I actually need to think about how to formulate this, with the intuitive Imperative solution constantly nagging in the back of my head. Did anybody else had this problem? How did you overcome this? Did you figured out a paradigm shift? Made a map from Imperative concepts to SQL concepts to translate Imperative solutions into Declarative ones? Read a good book? PS I'm not looking for a solution to the above query, I did solve it.

  • How to debug xsane "no devices available" error on 64 bit Ubuntu 10.04

    - by BD at Rivenhill
    I have a Brother MFC-J615W printer/scanner and I wish to use the scanning feature across a network with a computer running 64-bit Ubuntu 10.04. I have installed the drivers from the Brother website and followed all of the instructions, and printing works fine, but xsane (installed from repositories) produces a popup with the message "no devices available" on startup. I recently had success with a similar approach when installing drivers for a Brother MFC-495CW on 32-bit Unbuntu 9.10, so I am aware of issues such as requiring root access if the driver permissions are not set correctly, but running xsane as root does not solve this problem. Are there any tools available to debug this problem further or does anyone have advice on how to proceed?

  • What version of SCO Open Server are guys using out there and on what hardware?

    - by Gath
    I have some old applications which are running on SCO Open Server 5.0.5, and i would love to move them to SCO Open Server 5.0.7 and on modern hardware(servers), currently am running SCO on old IBM PL 300 personal computer, on 92MB Memory, one processor, and it has been serving the clients pretty well. Now i have New Modern IBM xseries Servers and i would love to migrate the same applications to those new servers. Problem is, SCO 5.0.5 is unable to detect some of the hardware components in the new servers. I read somewhere that SCO 5.0.7 is able to detect the newer hardware even the USB ports etc. Is there anyone running SCO Openserver out there, and on what hardware architecture are they running on?

  • Mainstream Linux on 1GB HDD

    - by Ariel Nundi
    Hi, I've decided to start learning Linux + Ryby + RoR. The problem is the only personal computer I have is a laptop with 1GB flash card and I can't afford to buy more hardware right now. The laptop has dual core CPU and 2GB of RAM. Can you recommend a Linux distribution I can install? I've tried the netbook version of Ubuntu, but install failed because of lack of space. I'd prefer a more popular distribution, so I can use my skills say on a job. TIA

  • Gigabyte GA-P55A-UD4P won't boot from USB drive with RAID enabled

    - by Daniel Schaffer
    I've got a Windows 7 installation image on my USB hard drive, which is set up to be bootable. I know it works because I've used it on several computers, and it works on the computer I'm trying to install as long as the RAID controller is disabled. However, when I enable the RAID controller and attempt to boot from the USB driver, it hangs for 30-60 seconds and then gives me the "disk boot failure, insert system disk" error like it can't find any OS. Just for laughs, I disabled the RAID controller again and it booted fine. I'm having separate, unrelated issues burning a dvd with the ISO, so I would prefer to get this working.

  • SQL SERVER – Simple Installation of Master Data Services (MDS) and Sample Packages – Very Easy

    - by pinaldave
    I twitted recently about: ‘Installing #sql Server 2008 R2 – Master Data Services. Painless.‘ After doing so, I got quite a few emails from other users as to why I thought it was painless. The reason was very simple- I was able to install it rather quickly on my laptop without any issues. There were a few requests along with these emails sent to me, which regards to how to install MDS, as well sample databases. Please note that I am the admin of my machine and I installed this MDS as the admin as well. Talk to your network administrator to figure out the best suitable settings for better security of login users. Additionally, since MDS is only supported on a 64-bit machine, I had rebuilt my computer a week before with a 64-bit OS and 64-bit SQL Server to go with it. Here is a quick picture tour of the installation. First of all, go to your SQL Server 2008. Install self-extracted folder and find the .msi file for C:\1033_enu_lp\x64\setup\masterdataservices.msi. Once you clicked on the file, follow the image tour below. You can ask me any questions in case you are still confused with any of the steps of the installation. While searching the internet for a similar installation process, I have landed on the official blog of MDS team where they have many interesting posts about it. If any concept written on my posts are contradictory to the information on the official blog, I suggest that you should follow the advice of official blog.
