Geotagging is the association of geographic location information with an object. A geotag comprises three pieces of information: a name and longitude and latitude values. Once files are geotagged, they can be indexed and searched based on the geographic information they contain. Here's how you can tag your photos, documents and other files so you can search for place-related information on your PC using Google Earth. Libferris is a virtual filesystem with index and search capabilities that allows you to geotag files. One reason the name libferris was chosen is because "ferris" sounds similar to VFS when said as "vee-fsss.
" A major advantage of using libferris to geotag is that you can tag anything that the virtual filesystem knows about. Examples of things that can be mounted and geotagged include email messages in Evolution, Web sites, URLs, a tuple in a PostgreSQL database, or an arbitrary triple in an RDF store. Different applications refer to geotags by different names. How To Implement SPF In Postfix. Version 1.0 Author: Falko Timme <ft [at] falkotimme [dot] com> Last edited 02/09/2007 This tutorial shows how to implement SPF (Sender Policy Framework) in a Postfix 2.x installation. The Sender Policy Framework is an open standard specifying a technical method to prevent sender address forgery (see There are lots of SPF extensions and patches available for Postfix, but most require that you recompile Postfix. Therefore we will install the postfix-policyd-spf-perl package from openspf.org which is a Perl package and can be implemented in existing Postfix installations (no Postfix compilation required).
I want to say first that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. 1 Preliminary Note I assume that you have already set up a working Postfix mail server. 2 Install Required Perl Modules perl -MCPAN -e shell install Mail::SPF q Then start the Perl shell again: or like this: Multiple-Document Interface (MDI) Applications. Multiple-document interface (MDI) applications allow you to display multiple documents at the same time, with each document displayed in its own window.
MDI applications often have a Window menu item with submenus for switching between windows or documents. In This Section Gives directions for creating the "container" for the multiple documents within an MDI application.

By Sean Carlos 12/01/2005 A crucial, if often overlooked, aspect of running a successful web site is the study of activity occurring within the site.
The information gleaned provides valuable input to continuous improvement initiatives, ranging from site architecture and content enhancements to traffic generation. This is the first of a two-part series exploring how to use the open source tool AWStats to perform web server log file analysis. This first part shows how to prepare a sample web log file, perform a basic installation of AWStats, generate reports, and review web analytics terminology; the second part will focus on report interpretation. Installing AWStats Web log analysis can be resource-intensive and usually takes place on a system different from the production web server(s). Binary executables for Linux (.rpm) and Windows (.exe) are available from the AWStats project home page and the AWStats project on SourceForge. . $ perl -v Preparing Web Server Log File Data LogFormat=1. How to Report Bugs Effectively.
By Simon Tatham, professional and free-software programmer [ English | Português | 简体中文 | Česky | Dansk | Deutsch | Español | Français | Magyar | Italiano | 日本語 | Nederlands | Polski | Русский | 繁體中文 ] Introduction Anybody who has written software for public use will probably have received at least one bad bug report. Reports that say nothing ("It doesn't work! "); reports that make no sense; reports that don't give enough information; reports that give wrong information. There's a reason why technical support is seen as a horrible job to be in, and that reason is bad bug reports. In this essay I'll try to state clearly what makes a good bug report. In a nutshell, the aim of a bug report is to enable the programmer to see the program failing in front of them. In bug reports, try to make very clear what are actual facts ("I was at the computer and this happened") and what are speculations ("I think the problem might be this").
"It doesn't work. " This essay is full of guidelines. "Show me. " RDP File Settings. Linux audit files to see who made changes to a file | nixCraft. This is one of the key questions many new sys admin ask: How do I audit file events such as read / write etc? How can I use audit to see who changed a file in Linux? The answer is to use 2.6 kernel’s audit system. Modern Linux kernel (2.6.x) comes with auditd daemon. In order to use audit facility you need to use following utilities => auditctl - a command to assist controlling the kernel’s audit system. => ausearch - a command that can query the audit daemon logs based for events based on different search criteria. => aureport - a tool that produces summary reports of the audit system logs. Note that following all instructions are tested on CentOS 4.x and Fedora Core and RHEL 4/5 Linux.
Task: install audit package The audit package contains the user space utilities for storing and searching the audit records generate by the audit subsystem in the Linux 2.6 kernel. Auto start auditd service on boot # ntsysv OR # chkconfig auditd on Now start service: # /etc/init.d/auditd start Where, Output: Remote Conversion to Linux Software RAID-1 for Crazy Sysadmins HOWTO. Vesion 0.2 Copyright 2004 Warren Togami Hits:10499 Table of Contents Introduction and Disclaimer Revision History Acknowledgements Procedure Appendix 1. Introduction XXX: Write me This is a guide for converting Linux servers installed on a single disk to software RAID-1 mirror with a second identical hard disk entirely remotely with only ssh access. This procedure has been tested successfully on Red Hat Linux 9, Fedora Core 1, and RHEL4.
RHEL3 was also tested, but as noted within the procedure one key method of starting RAID arrays failed and I could never figure out why. This procedure was figured out because I wanted to convert my Serverbeach dual hard drive server into RAID-1, but they don't offer that configuration. DISCLAIMER: This is normally a very DANGEROUS procedure, and you can very easily leave your system in an unbootable dead state.
Do not e-mail Warren asking for help, especially if you screwed up your server. 2. Version 0.2 - May 27, 2005 * Add some RHEL4 notes 3. 4. Linux Kernel Magic SysRq keys in openSUSE for crash recovery | SUSE & openSUSE. The Linux Kernel offers you something that allows you to recover your system from a crash or at the least lets you to perform a proper shutdown using the Magic SysRq Keys. The magic SysRq key is a select key combination in the Linux kernel which allows the user to perform various low level commands regardless of the system’s state using the SysRq key.
It is often used to recover from freezes, or to reboot a computer without corrupting the filesystem. The magic Sysrq key basically has a key combination of <ALT> + <SysRq or Prnt Scrn> + <Command key>. The command key can be one of the following providing a specific functionality ‘b’ – Will immediately reboot the system without syncing or unmounting your disks. ‘c’ – Will perform a kexec reboot in order to take a crashdump. ‘d’ – Shows all locks that are held.
The most useful combination is the <ALT>+<SysRq or Prnt Scrn> + R-E-I-S-U-B REISUB will This could avert or atleast reduce the impact of system crashes. Click System and Kernel Settings. eHow.com - Clear Instructions on How To Do (just about) Everything.
