• optimizing operating systems to provide maximum informix performance.

  - by Frank Developer

  Are there any Informix-specific guides for optimizing any operating system where an ifx engine is running? For example, in Linux, strip-down to a bare minimum all unecessary binaries, daemons, utilities, tune kernel parameters, optimize raw and cooked devices (hdparm). Someday, maybe, informix can create its own proprietary PICK-like O/S. The general idea is for the OS where ifx sits on have the smallest footprint, lowest overhead impact on ifx and provide optimized ifx performance.

• How to stop Microsoft IntelliType Pro (itype.exe) from interpreting keys

  - by Asaf R

  Intellitype Pro is a nice software that helps me when I'm using my Ms keyboard. When I'm on the road using my laptop's built-in keyboard it interprets some of the keys incorrectly and reacts on them, for instance the Fn + Down Arrow opens Windows Live Messenger (in addition to lowering brightness, which is governed by Dell's driver). I want to stop Intellitype when I'm on the road and reload it when I'm home using the external keyboard. Note: original problem (conflict with itype) posted here.

• What is the best way to downscale mp4 video while keeping it as sharp as possible?

  - by Brandon Durham

  I've got an .mp4 file that's currently 830x1100 (it's a screencast) that I need to resize down to 114x150. I've been experimenting for hours with ffmpeg settings and nothing comes out looking nice and sharp. The original file looks decent, and I can't figure out why the downscaling makes it look so blurry. Unfortunately I can't share the video because it contains a walkthrough for software that hasn't yet been released.

• Any rerefence of CPU world statistics?

  - by Áxel Costas Pena

  I am looking for any referencee about computer power statistics across the world. My main interest is about real computing capabilities, so I'd prefer information about real processor power, and even best if it includes also other critical hardware statistics, like RAM memory, but if it isn't possible, maybe statistics about brand/model distribution will be also useful. I've Googled for some minutes and I've found nothing related.

• Windows 7 backup and restore: Is each backup incremental or complete?

  - by Margaret

  I have a computer that's been taking backups using Windows 7's Backup and Restore feature. However, I now need to reclaim hard disk space, and am trying to figure out what I can safely delete. When I go into the Backup and Restore options on the machine, it shows several backups. Is it safe to delete the older ones? Or is it an incremental backup, that means that files not changed since before the last backup would then be lost?

• How do I remove initial indents on numbered lists?

  - by Peter

  In Word 2007 I want all numbers in a numbered list to be down the LH margin in line with the paragraphs. When a numbered list is selected, the numbers 1,2,3 are indented by a default 0.63cm. Ctrl-Shift-M will shift this indent back to the left margin. How do I permanently remove that initial indent and save that change to the normal template so that all new documents have zero indent on a newly inserted numbered list? (Same issue in Word 2010)
