Encrypted NFS with OpenSSH |
| Post date: May 21, 2005, 14:05 Category: Network Views: 876 Comments: 0 |
| Tutorial quote: NFS is a widely deployed, mature, and understood protocol that allows computers to share files over a network. The main problems with NFS are that it relies on the inherently insecure UDP protocol, transactions are not encrypted, hosts and users cannot be easily authenticated, and its difficulty in firewalling. This article provides a solution to most of these problems for Linux clients and servers. These principles may also be applied to any UNIX server with ssh installed. This article assumes basic knowledge of NFS and firewalling for Linux. |

Furthermore, there are situations where Postfix may not perform as well as you expected, whether because of hardware or software limitations on the server system or other adverse conditions, such as a big influx of spam or undeliverable mail. This article shows you how to find and analyze the most common performance problems. |

Introduction to Free Pascal 2.0 |
| Post date: May 16, 2005, 18:05 Category: Programming Views: 1095 Comments: 0 |
| Tutorial quote: After five years of development, Free Pascal 2.0 is ready. With the new compiler, its authors believe they are ready to become a larger open source development platform. In the MS-DOS world, Pascal was one of the major programming languages and is by means of Borland Delphi an important programming language in the Windows world. In the open source world, Free Pascal is the leading Pascal compiler and while open source is a bit biased using the C language, the Pascal language has a lot to offer to open source programmers. |

Automating Perl Database Applications |
| Post date: May 1, 2005, 12:05 Category: Programming Views: 953 Comments: 0 |
| Tutorial quote: This article describes how Perl is used to generate Perl CGI code using the multi-platform CGIScripter application. The resulting output code automates SQL table creation commands (in this example, for a MySQL database), HTML pages and Perl code. Web security issues, data validation and image handling functionality are incorporated into the resulting Perl code. By automating the development of Perl CGI scripts, even entry-level developers can create CGI scripts that contain most of the commonly requested features in a short period of time--without manually writing any code. |

Good-looking fonts in X Windows |
| Post date: April 23, 2005, 04:04 Category: Desktop Views: 851 Comments: 0 |
Tutorial quote: What makes the difference betweek "ugly" and "beautiful" fonts? Several things.
One of them is anti-aliasing (or AA in short). It's the technique which adds gray pixels in various shades around the edges of black text and thus blurs the jagged and pixelated edges. It works with other colors, too.
Another thing is having good quality fonts to start with. Font which are ugly by nature or don't scale well to various sizes are not much nicer when anti-aliased. See what kinds of fonts are out there by browsing through the Font HOWTO (not the same as the FDU HOWTO above).
Finally, there's the issue of readability which applies to you directly. How well does the end-product look anyhow? Do you really need anti-aliasing for an 8 pixel text? And other similar questions, which you'll learn how to answer according to your own preferences. |
