Influence scheduling priority with nice and renice

  • Linux.com; By Evi Nemeth, Garth Snyder, and Trent R. Hein (Posted by Scott_Ruecker on Nov 29, 2006 8:20 PM EDT)
  • Groups: Kernel; Story Type: News Story
The "niceness" of a process is a numeric hint to the kernel about how the process should be treated in relation to other processes contending for the CPU. The strange name is derived from the fact that it determines how nice you are going to be to other users of the system. A high nice value means a low priority for your process: you are going to be nice. A low or negative value means high priority: you are not very nice. The range of allowable niceness values is -20 to +19.

LDAP Series Part V - Grtting a Grip on Directory Service Modeling

I have an observation I'd like to disclose about the Open Source community: we tend to leap into all kinds of things before we have all the facts and/or information necessary to make intelligent decisions. We criticize other communities, laugh at things like directory services from the two major NOS players, talk about all our great applications, etc. we hang on to old notions about a what makes Linux tick. Sorry, but that model Eric doesn't fit any more. The community natter appears to come mostly from people who lack deep technical skills and knowledge of enterprises.

Linux gaming: don't sell your Xbox

It's not that you can't run WoW (World of Warcraft) on Linux. With the latest CrossOver Office beta, you can do exactly that. Indeed, Lynch found that running World of Warcraft "ran so well that I began to get distracted from writing this review and started to get sucked into the world of Azeroth. I kept playing and didn't even realize that I was running WoW in a window on my KDE desktop in PCLinuxOS."

TWC's customers are local cable television facilities and individual Web site users. To manage those customers effectively, TWC chose an open source customer relationship management (CRM) application called Centric.

O3spaces Challenges MOSS for Team Collaboration

Hoping to level the playing field with Microsoft SharePoint and perhaps make a little open source cheddar, Dutch software outfit O3 is releasing its O3Spaces back office suite for OpenOffice and StarOffice. While it is far from offering all of the features of SharePoint (MOSS) 2007, it is definitely something that that open source and hybrid Microsoft/open source shops should consider for document management.

Linux box built out of an Apple Studio Display

While the vast majority of recent Mac modifications have dealt with the headless Mac Mini, the Toolman decided to go a different route with his gutted 17-inch Apple Studio Display. As with most mods, he simply had too many enticing parts lying around without a proper home, and chose to combine them using whatever it took, resulting in a Mac-ish clone at worst, and a sweet all-in-one computer at best.

Test-driving Adobe's Flash Player 9 beta

The stable Flash Player plugin for Linux is crusty old version 7 -- trailing more than two calendar years, two major revisions, and one corporate buyout behind the Windows and Mac offerings. But now Adobe has finally unveiled a beta release of Flash Player 9 for Linux. Was it worth the wait?

Tip of the Trade: TestDisk and PhotoRec

Murphy's Law dictates that you can always count on Bad Things happening. That probably explains why the software world has so many different recovery utilities for accidentally (or purposely) deleted files. These vary in ease of use, though typically "easy" is not a word that applies. Except for a pair of excellent data recovery tools, TestDisk and PhotoRec. (That's "rec" as in "recovery," not "wreck".)

Quick and dirty Samba setup

Samba is an open source project that allows Windows users to connect to a Linux server from which to share data. If you are looking for a simple, affordable home file server, or need more disk space on your office network, a Linux server with Samba is the way to go. Linux along with Samba offers a stable, secure environment that is available at no cost, along with features such as remote administration, immunity to Windows viruses, and the ability to run on low-end machines. Here's how you can set up a simple Samba server on Slackware for SOHO use.

Bad SuSE experiences

LXer Feature: 29-Nov-2006

Recently, LXer asked you: Which Linux distribution is the best? SuSE Linux came along several times. I have tried to work with SuSE Linux, but I only had bad experiences. Nonetheless, I'm not sure if it's SuSE / Novell who I should blame, there are more factors. I am only an amateur / hobbyist, so I could be the one to blame. On the other hand, I have experience with Open/Net/FreeBSD, Slackware, Debian, Ubuntu, Knoppix, a lot of it with Gentoo, and I hold an LPIC 1, so you can't say I don't have experience. I don't know anyone else in my neighbourhood who's good with SuSE, so there's no hands-on support. Moreover, I ran Suse on Microsoft Virtual PC (R), so we could also blame Microsoft (as usual). Or didn't I try hard enough? Fact is, I am dissastified with SuSE to such a level, I won't use it for the coming few months probably.
