  • Huge excel sheet taking too long to update links or calculate formulae

    - by user7231
    I have Excel sheet with 5000 rows and columns till AY (size 12MB). Except for the first 6 columns, rest contain either vlookups or formulae. All the vlookups are in separate Excel sheet. I have changed the Excel setting to manually update the links and calculate formulae. Now everytime I try to update the links, either the Excel sheet hangs or it takes something like 15 minutes. Any ideas on how I can get it done quickly.

  • Create keyboard shortcuts to move/resize windows in Ubuntu

    - by Herms
    On windows I have a few AutoHotkey scripts that let me hit various key combinations to resize windows to particular pre-defined sizes, or move them to certain areas of the screen (or both). I'm wondering how I would accomplish this in Ubuntu (gnome). Most of the searches I did for a linux version of autohotkey seemed to be centered around just setting up simple keyboard shortcuts (key combo X launches app Y, etc). I didn't see anything about scripting window size and placement beyond maximize/minimize.

  • open 500 mb, 4 million record csv file

    - by Giorgi
    Hello, I have a csv file which has about 4 million rows and is about 500MB in size. Can you recommend any editor that can open the file without making the system crawl? I tried EmEditor but it is complaining that there are too many characters in a single line. Thanks.

  • Automatic Edit Photoshop Canvas Dimensions in Bulk

    - by Josiah
    On a website that I maintain I am required to edit hundreds of images to have a certain canvas size. The images come in all different shapes and sizes. I am trying to figure out a way to automatically edit them so that I dont have to write ineffective AHK scripts to do it. Is there a feature inside of Photoshop (cs3) to do this? I am more than willing to try different software. Thanks guys!

  • Get WebDav uploading progress and status (Linux, davfs2)

    - by Hnatt
    I am using WebDAV on Linux box with davfs2 1.4.6. When I copy a file to a mounted WebDAV service, it is goes rather fast, just like a regular local drive operation. And it actually is, because the file is first copied to ~/.davf2/cache directory. But how do I know that uploading is finished and where do I see current progress? Is there a way to know that uploading failed due to lack of space or file size restrictions?

    I would like my external drives to be readable and writable from Linux, Mac OS X and Windows. FAT32 works, but the 4 GB file size limit is a showstopper these days. Are there any alternatives?

  • Why is cleartype so bad at high res?

    - by ULTRA_POROV
    Cleartype is great when displaying small text 10 - 16px HOWEVER when you display something above 20px it start's looking like shit. Just compare it to Photoshop. Photoshop rendering at small size is not very impressive, too blurry. But if you compare it at 20px + Photoshop wins all the time. Cleartype looks jaggy around the edges, almost like there is no cleartype at all. Can this be fixed, or is it just the way cleartype is?

  • How do I full-screen my CMD?

    - by Codemonkey
    I work a LOT in the windows command line. Unlike other windows, it doesn't maximize - it just goes a big as it can depending on the buffer size. Is there any way I can get the CMD to act like the PuTTY console, flowing with the resize? NOTE: The answer doesn't have to be a tweak to the CMD. If there's a PuTTY-like program out there that will work between me and the command line I'm happy with that - I just want a proper window to work in

  • linux disk usage report inconsistancy after removing file. cpanel inaccurate disk usage report

    - by brando
    relevant software: Red Hat Enterprise Linux Server release 6.3 (Santiago) cpanel installed 11.34.0 (build 7) background and problem: I was getting a disk usage warning (via cpanel) because /var seemed to be filling up on my server. The assumption would be that there was a log file growing too large and filling up the partition. I recently removed a large log file and changed my syslog config to rotate the log files more regularly. I removed something like /var/log/somefile and edited /etc/rsyslog.conf. This is the reason I was suspicious of the disk usage report warning issued by cpanel that I was getting because it didn't seem right. This is what df was reporting for the partitions: $ [/var]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 9.9G 511M 8.9G 6% / tmpfs 5.9G 0 5.9G 0% /dev/shm /dev/sda1 99M 53M 42M 56% /boot /dev/sda8 883G 384G 455G 46% /home /dev/sdb1 9.9G 151M 9.3G 2% /tmp /dev/sda3 9.9G 7.8G 1.6G 84% /usr /dev/sda5 9.9G 9.3G 108M 99% /var This is what du was reporting for /var mount point: $ [/var]# du -sh 528M . clearly something funky was going on. I had a similar kind of reporting inconsistency in the past and I restarted the server and df reporting seemed to be correct after that. I decided to reboot the server to see if the same thing would happpen. This is what df reports now: $ [~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 9.9G 511M 8.9G 6% / tmpfs 5.9G 0 5.9G 0% /dev/shm /dev/sda1 99M 53M 42M 56% /boot /dev/sda8 883G 384G 455G 46% /home /dev/sdb1 9.9G 151M 9.3G 2% /tmp /dev/sda3 9.9G 7.8G 1.6G 84% /usr /dev/sda5 9.9G 697M 8.7G 8% /var This looks more like what I'd expect to get. For consistency this is what du reports for /var: $ [/var]# du -sh 638M . question: This is a nuisance. I'm not sure where the disk usage reports issued by cpanel get their info but it clearly isn't correct. How can I avoid this inaccurate reporting in the future? It seems like df reporting wrong disk usage is a strong indicator of the source problem but I'm not sure. Is there a way to 'refresh' the filesystem somehow so that the df report is accurate without restarting the server? Any other ideas for resolving this issue?

  • Set Custom/default font in Gmail

    - by Rishi
    Gmail does not let me set my default font settings Is there a shortcut to use a font which I use regularly? Adjusting Font type and size in every email is a laborious job. EDIT: Any feature involving very few clicks will do (should not be dependent on any other application)

  • Change TCP wait for ACK timeouts in Win7/WinServer

    - by maseth
    Is there any possibility to change default wait for ACK timeout in TCP network on Windows 7 or Windows Server ? I'm using very slow network ( 1200 bps ) and want to tweak TCP. When using default parameters network stuck on multiple retransmissions . If I'm able to change the ACK timeout and tx window size I think that it would work. On Windows XP it was possible but cant find any document for Win7 and Win Server.

  • MongoDB and datasets that don't fit in RAM no matter how hard you shove

    - by sysadmin1138
    This is very system dependent, but chances are near certain we'll scale past some arbitrary cliff and get into Real Trouble. I'm curious what kind of rules-of-thumb exist for a good RAM to Disk-space ratio. We're planning our next round of systems, and need to make some choices regarding RAM, SSDs, and how much of each the new nodes will get. But now for some performance details! During normal workflow of a single project-run, MongoDB is hit with a very high percentage of writes (70-80%). Once the second stage of the processing pipeline hits, it's extremely high read as it needs to deduplicate records identified in the first half of processing. This is the workflow for which "keep your working set in RAM" is made for, and we're designing around that assumption. The entire dataset is continually hit with random queries from end-user derived sources; though the frequency is irregular, the size is usually pretty small (groups of 10 documents). Since this is user-facing, the replies need to be under the "bored-now" threshold of 3 seconds. This access pattern is much less likely to be in cache, so will be very likely to incur disk hits. A secondary processing workflow is high read of previous processing runs that may be days, weeks, or even months old, and is run infrequently but still needs to be zippy. Up to 100% of the documents in the previous processing run will be accessed. No amount of cache-warming can help with this, I suspect. Finished document sizes vary widely, but the median size is about 8K. The high-read portion of the normal project processing strongly suggests the use of Replicas to help distribute the Read traffic. I have read elsewhere that a 1:10 RAM-GB to HD-GB is a good rule-of-thumb for slow disks, As we are seriously considering using much faster SSDs, I'd like to know if there is a similar rule of thumb for fast disks. I know we're using Mongo in a way where cache-everything really isn't going to fly, which is why I'm looking at ways to engineer a system that can survive such usage. The entire dataset will likely be most of a TB within half a year and keep growing.

  • MySQL Backup - incremental

    - by Tiffany Walker
    I know that you can use mysqldump. I am currently dumping the following way: ${MYSQLDUMP} --single-transaction -u ${MUSER} -h ${MHOST} -p${MPASS} $db | ${GZIP} -9 > $FILE From my understanding this locks the database and prevents any type of use of the database and can even lock up websites. Is there a better way to maybe do daily/hourly backups of the MySQL database should the database be in the 100mbs and even 1gbs in size?

  • Is pst file enough to backup my Outlook (Gmail)?

    - by Hasan Gürsoy
    I've backup from my Gmail account at Outlook 2010 beta. I see a pst file which is equal file size with my Gmail used storage. Is this file enough to protect my mails or do I need additional files or whatever? I'm not a regular outlook user. I've read this but I don't think I'm using "Signatures, Templates, Stationery etc."...

  • Why do my VMware Images get so large?

    - by stevebot
    Hi, I have a Centos VMware Image that I have recreated a couple times, and I notice that after a while it gets pretty large. It starts out at 8 GBs when I make it, and a week or two later it is 25GB and then a month later it is a whole 50GB or so. I am not installing anything crazy on it, and my disk usage on the VM is pretty low. Is there an option that could be affecting the size of these VMs?

  • How to configure sendmail to relay through a specific server

    - by ErebusBat
    I have a tiny home server setup behind my cable modem (bresnan communications). I want to be able for this box to send out email (not receive) for notifications and whatnot. What I have already done: I have installed and configured sendmail. I have added mail.bresnan.net as my SMART_HOST directive. What I belive the problem is When I attempt to send an email I get the following in my mail log: Dec 22 10:24:17 batcave sendmail[1530]: oBMHOHrs001530: from=aburns, size=140, class=0, nrcpts=1, msgid=<[email protected]>, relay=aburns@localhost Dec 22 10:24:17 batcave sm-mta[1531]: oBMHOHWZ001531: from=<[email protected]>, size=397, class=0, nrcpts=1, msgid=<[email protected]>, proto=ESMTP, daemon=MTA-v4, relay=localhost [127.0.0.1] Dec 22 10:24:17 batcave sendmail[1530]: oBMHOHrs001530: to=<[email protected]>, ctladdr=aburns (1000/1000), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30140, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (oBMHOHWZ001531 Message accepted for delivery) Dec 22 10:24:18 batcave sm-mta[1517]: oBMH9mVv001357: to=<[email protected]>, ctladdr=<[email protected]> (1000/1000), delay=00:14:30, xdelay=00:00:42, mailer=relay, pri=300339, relay=pmx0.bresnan.net. [69.145.248.1], dsn=4.0.0, stat=Deferred: Connection timed out with pmx0.bresnan.net. You can see where the message is accepted for delivery by my sendmail server, then where it attempts to hand off to bresnan's server and it timesout. This is where my question is. Asstute readers will notice that pmx0.bresnan.net is not what I have my SMART_HOST directive set as. This is the (outside?) MX server for the bresnan.com/net domain. Apparently bresnan has their network configured so that you can not access this server from within their own network and instead must use the mail.bresnan.net server (which I can connect to). The problem is that I don't know how to tell sendmail to use this server and not the domain. What I have tried Setting a hosts entry so that the pmx0 server points to the mail IP address. This doesn't work, which makes sense as sendmail is obviously doing an MX query to find the server which returns the IP so there is never a need to do a 'normal' DNS resolve so the hosts file never gets involved.

  • Want to automate adding Hidden photos to iPhoto using a folder action

    - by Gekitsuu
    I'm trying to find away to create an automator action that puts photos into iPhoto but also adds the hidden tag to them. I've started with the folder action template because I'd like to save the files there and have automator kick off a series of steps that ends with the original image being hidden once I've had the enhancement, re-size, etc steps fire off. The only step I can't figure out is applying the hidden image attribute.
