• How to check if cell contains a value of another cell

  - by Antonio Oliveira

  Here is the scenario: On column A each cell has random text within it (names, address, account numbers, etc). Column A extends down to over 40 thousand rows. On column B I have a list of (account) numbers. Column B extends down to about 5 thousand rows. I need to filter column A to show only the rows that contain the account numbers that are part of column B. Neither column A nor B are in any specific order. I think he above scenario speaks for itself, but I can provide a quick example if needed (don't want to over complicate it).

• Serial Port ttyUSB0

  - by Alex

  I picked up a USB serial null modem cable, so that I can connect up to a headless linux box. As a quick test, I plugged the device into the usb null modem, and the other end I connected to a windows pc. I opened up a terminal on the windows side, with 115200 8N1. On the linux side I opened minicom with the same params. MY problem is that I can type one way from the pc and see the text on the linux minicom side. If I type on the linux side it doesnt show on the pc side. If I reverse the cable it reverses the process. I bet this is a simple issue but I haven't dealt with serial comms in ages. Thanks

• Leaving job, PC personal info deletion guide?

  - by bangoker

  I'm quitting my current job, and I want to make sure all my personal stuff gets whipped off the computer. I know everybody stores stuff on different places, but is there any quick guide of locations (folders) and apps that might need deletion? you know, just to be sure I erased from all the places and I don't forget any (like those were apps save stuff automatically, the data folders and such) I have erased most of my docs in My Document folder, and I am going to erase all the cookies and stored history in my browsers (opera, ie, ff, chrome) (by the way is there any tool for this?)

• How to close buffer without closing the window?

  - by progo

  I usually open a few windows and keep some buffers open. Since my MO in buffer exploring is to use quick shortcuts to :bn and :bp, I want to close unneeded buffers from distracting my buffer surfing. But the pain is, issuing :bd and :bw results in closing the window as well, in case I have multiple ones open. How do I close (delete) a buffer and leave the windows intact? Solution inspired by @peth's answer :command! BW :bn|:bd# It is simple. Doesn't work well with only one buffer open (I get different behaviour depending on the way I open the files) but it isn't a big issue. :)

• MSSQL 2008 is claiming the firewall is blocking ports even from local machine

  - by Mercurybullet

  I was just hoping to step through a couple queries to see how the temp tables are interacting and I'm getting this message. The windows firewall on this machine is currently blocking remote debugging. Remote debugging requires that the debugging be allowed to receive information from the network.Remote debugging also requires DCOM (TCP port 135) and IPSEC (UDP 4500/UDP500) be unblocked Even when I walked over to the actual machine and tried running the debugger, I'm still getting the same message. Am I missing something or does the debugger try to run remotely even from the local machine? Since this was meant to be just a quick check, I don't need instructions on how to open up the firewall, just hoping there is a way to run the debugger locally instead.

• How do you change color of gradient image found on the net?

  - by askmoo

  For example, I found this gradient image (randomly chosen) How do you change its color in Photoshop or GIMP? I tried overlay but it covers everything with that color. For example I want to have white-to-red gradient image. Possible to do it in a quick way via any of these tools or I have to make it from the scratch? This is the image before and after I use the tool suggested. You can see the horizontal striped on the after image.

• Options to efficiently synchronize 1 million files with remote servers?

  - by Zilvinas

  At a company I work for we have such a thing called "playlists" which are small files ~100-300 bytes each. There's about a million of them. About 100,000 of them get changed every hour. These playlists need to be uploaded to 10 other remote servers on different continents every hour and it needs to happen quick in under 2 mins ideally. It's very important that files that are deleted on the master are also deleted on all the replicas. We currently use Linux for our infrastructure. I was thinking about trying rsync with the -W option to copy whole files without comparing contents. I haven't tried it yet but maybe people who have more experience with rsync could tell me if it's a viable option? What other options are worth considering?

• Force Windows 8 Metro apps to run lower resolutions below 1024x768?

  - by piokuc

  I have installed Windows 8 Consumer Preview on my Samsung NB30 netbook. I was very excited to try it on this little box cause it has a touchscreen and Windows 8 is supposed to be optimized for touchscreen devices. The installation was quick and smooth and all the drivers seem to work well including the one for the touchscreen. There is one major problem, though: when I try to tap one of the tiles on the Metro UI it displays This app can't open. The screen resolution is too low for this app to run. The machine has Intel Atom N450 processor and Intel GMA 3159 integrated graphics card and has maximum resolution 1024x600. I've read that Metro requires at least 1024x768. Is there a solution to this problem? Is there a way to force Windows 8 Metro apps to run in lower resolutions?

• rename multiple files with unique name

  - by psaima

  I have a tab-delimited list of hundreds of names in the following format old_name new_name apple orange yellow blue All of my files have unique names and end with *.txt extension and these are in the same directory. I want to write a script that will rename the files by reading my list. So apple.txt should be renamed as orange.txt. I have searched around but I couldn't find a quick way to do this.I can change one file at a time with 'rename' or using perl "perl -p -i -e ’s///g’ *.txt", and few files with sed, but I don't know how I can use my list as input and write a shell script to make the changes for all files in a directory. I don't want to write hundreds of rename command for all files in a shell script. Any suggestions will be most welcome!

• Setting differing ACLs on directories and files

  - by durandal

  Quick ACL question: I want to set up default permissions for a file share so that everyone can rwx all of the directories and so that all newly created files are rw. Everyone who is accessing this share is in the same group, so this isn't a concern. I have looked at doing this via ACLs without changing all of the users' umasks and such. Here are my current invocations: setfacl -Rdm g:mygroup:rwx share_name setfacl -Rm g:mygroup:rwx share_name My problem is that while I want all of the newly created sub-directories to be rwx, I only want newly created files to be rw. Does anyone have a better method to achieve my desired end-result? Is there some way to set ACLs on directories separately from files, in a similar vein to "chmod +x" vs. "chmod +X"? Thanks

• Set an Excel cell's color based on multiple other cells' colors

  - by Lord Torgamus

  I have an Excel 2007 spreadsheet for a list of products and a bunch of factors to rate each one on, and I'm using Conditional Formatting to set the color of the cells in the individual attribute columns. It looks something like this: I want to fill in the rating column for each item with a color, based on the color ratings of its individual attributes. Examples of ways to determine this: the color of the category in which the item scored worst the statistical mode of the category colors the average of the category ratings, where each color is assigned a numerical value How can I implement any or all of the above rules? (I'm really just asking for a quick overview of the relevant Excel feature; I don't need step-by-step instructions for each rule.)

• PHPMyAdmin running very slow over internet but fine locally

  - by columbo

  I connect to PHPMyAdmin remotely on a Centos server using my local PC via Firefox. Usually it's fine but today it's really slow (2 minutes to load a page), sometimes timing out. Other connections to the server are fine. The SSH command line is as fast as ever as is the GNOME dekstop over SSH. In fact on the GNOME desktop I can run PHPMyAdmin locally from its browser and it's as quick as ever (which is a solution to the problem of course). I've checked the various log files and seen nothing unusual, I've logged into the MySQL command line and the database is running fine without any slowing what so ever. So it just seems to be slow when I access PHPMyAdmin on the server from the browser on my remote PC (I've tried IE and Firefox, both are slow). Has anyone experienced this or have any ideas what the issue could be. Connecting via CLI through tunnel works OK - problem is in phpMyAdmin for sure. Cheers

• How SmartDNS Works

  - by Emad

  If you travel outside the US you'll notice that most of the streaming services like Netflix, Pandora, hulu etc are blocked, usually by the service providers themselves. To get around that, people use VPN services. They basically tunnel your traffic through a US server so your requests seem like they are originating in the US. These VPN services fix this blocking problem, but make your connection slower than the normal unVPNed connection. Recently however I've come across something called SmartDNS provided by overplay.net. You pay $5 a month and you get access to their DNS servers. After you change to their DNS you get access to the blocked streaming sites, without slowing down your normal traffic like email and browsing. What I'd like to know is the technical details of how this SmartDNS works. I've done some quick research but that didn't turn up anything of substance. Anybody out there knows?

• Exchange 2007 automatically adding IP to block list

  - by Tim Anderson

  This puzzled me. We have all mail directed to an ISP's spam filter, then delivered to SBS 2008 Exchange. One of the ISP's IP numbers suddenly appeared in the ES2007 block list, set to expire in 24 hours I think, so emails started bouncing. Quick look through the typically ponderous docs, and I can't see anything that says Exchange will auto-block an IP number, but nobody is admitting to adding it manually and I think it must have done. Anyone know about this or where it is configured? Obviously one could disable block lists completely but I'd like to know exactly why this happened.

• Unable to format/add a partition to Windows XP

  - by sma

  I recently add a 1T disk to an XP machine. I found the disk in the "disk management", I click "initialize" to init it, then creates a primary partition with size 950G, then select quick format to format the disk, the "disk management" will then complains: The disk configuration operation did not complete. Check the system event log for more information on the error. Verify the status of your storage devices before retrying. If that does not solve the problem, close the disk management console, then restart disk management or restart the computer. What could be the reason?

• Fastest booting Linux ditribution on a live-cd

  - by Avindra Goolcharan

  I'm looking for a linux distro with the following: Boots quickly, as fast as possible. Has expected tools such as file browser, a web browser, etc. Doesn't need to have extraneous recovery stuff such as partition editors, and what not. These are the tools I have and use already: ophcrack Ultimate Boot CD for Windows (UBCD4Win) chntpw (Offline NT Password and Registry Editor) Hiren's BootCD gparted or Parted Magic Ubuntu nubuntu Any and all suggestions are welcome :-) The primary objective is to get a quick booting linux distro that I can grab / delete / move / copy files with. Currently, I prefer using ophcrack, it boots in (relatively) fast and I can manipulate files well. The one that takes the longest is ubuntu of course.

• Sennheiser PC360 Microphone Suddenly Stopped Working

  - by Michaelwm

  Just recently, my Sennheiser PC360's microphone stopped working. Yesterday Night, it was working 100% fine. Muting correctly, un-muting, volume boosting, etc. I woke up this morning, and got into a skype call (After not changing a single setting on my computer), and it wasn't working. I tried mumble, and it didn't work there either. After that, I checked my sound devices and found out it was plugged in, but not responding to my voice. I unplugged the headset, and it correctly showed that it was unplugged. So, a quick run-down: Sennheiser PC360 Headset suddenly stops working after a few hours of sleep. Software is up to date I can hear the mute sound when I raise and lower the microphone arm Windows Sound Device Manager shows that it is plugged in Unplugging the headset correctly shows it is unplugged Windows Sound Device Manager shows that the microphone isn't receiving any input

• Embed Powershell prompt in Windows 7 desktop

  - by EricRRichards

  On Linux (last time I did this was with Compiz on Ubuntu 11), I like to have a transparent console window anchored to the desktop, so I can get to a shell just by clicking out of whatever I'm doing and don't have to play with with moving/resizing windows. I'd like to do something similar on Windows 7/Server 2008. I could probably write up a quick little app in .Net that would run fullscreen and have a powershell terminal embedded in it, but, if somebody has already created something sufficient, or there is some other hackery to do this, I don't want to reinvent the wheel. Another possibility could be a Quake-style pulldown console, similar to Guake (guake.org).

• MDT Image Hierarchy

  - by Antix

  Just a quick question, I couldn't find this out by looking around and have not had the time to run a test myself: Is it possible to create image hierarchies in MDT? Take this example where we have three images. - Image 1: Base OS - Image 2: Company Wide Applications (built off Image 1) - Image 3: Specific Role Applications (built off Image 2) Now just say we change the version of an application in Image 2. The next time we build Image 3, will this take the new version of the application since it's basing its image off Image 2? Also, If we add a program to Image 1, leave Image 2 unchanged and re-build Image 3, would this include the new program? I'm trying to plan out a way of creating images such that if a change is required for an image that is on basically every machine (think, Image 1) then we only have to change it in one location. Has anyone actually done something like this and has any tips?

• Block Websites at Work

  - by user791022

  At work there are about 40 PCs. I want to block all the websites and only allow a few Domains/Websites for operators. A few operators can access anything. I want something quick and easy so I can filter the Block/Allow websites for all computers from one main computer, like a server or something. Windows Vista Home and Windows 7 Home are installed on the PCs. Is there any software can do this? PS: Please don't answer about Microsoft Windows Server OS..

• How to work with bookmarks in Word without naming them?

  - by deepc

  I am working in a large Word 2007 document and need bookmarks to remember editing positions. I know I can manage bookmarks with shift+ctrl+F5 but that's cumbersome because I am used to do this a lot faster in the Delphi editor. There I create a bookmark with ctrl+shift+0..9 and jump to the bookmark with ctrl+0..9. In this way I have 10 quick bookmarks. I do not have to name them, I do not have to pick them from a dialog (because there is not even a dialog prompting me for a selection). Is something similar possible in Word, or has anybody made a macro for that purpose? Thanks.

• Can I use Veritias Storage Manager to provide HA storage using server-local storage?

  - by Paul

  I have a need to provide an high-availability ftp/http file repository. Upload will happne to one server, but the uploaded file must be immediately visisble on all other servers I can handle the failover of the servers themeselves using load balancers. But in the event of failure of one server, the other servers must see the same contents of the repository. Normally, I'd use a SAN for this, but in this case the data centre standards do not allow SAN/external storage - all storage will be local to the servers. Cam I use Veritas Storage Manager (or any other product) to manage mirroring hte contents between servers in this way? Or does that require a SAN? I couldn't tell either way from a quick look at the data sheets etc.

• My Domain Is Getting Blocked As Gambling

  - by Tim Scott

  I have a site at http://slotted.co. Some of my would-be users complain that their company firewall blocking access. At least one user told me it was flagged as a gambling domain, which it is not. What can I do about this? Incidentally I own some other domains, such as signupster.com, which redirect to my site. I wonder if a quick workaround would be to make that my main domain and have slotted.co redirect? Obviously I prefer in the long terms that slotted.co is considered clean.

• Why is my PC boot time slow when USB HDD attached?

  - by John

  I have a USB Hard disk that I am using as a secondary drive just for extra storage. When this is attached and I start my PC the second screen says searching for mass storage dives for about 5 minutes before continuing on. The same happens when I have a USB pen disk attached upon boot. If I attach the device after the PC has loaded then it is very quick however plugging and unplugging is not ideal. Is there away to disable this in the BIOS as I cannot instantly see an option. On boot it informs me I have an American Trends AMIBIOS in the BIOS setup it states the version as v02.58 2006. This is running on a ASUS MV2 Motherboard.
