Eclipse Rich Client Platform (RCP) with Eclipse Ganymede (3.4)

The Eclipse Rich Client Platform (RCP) allows developers to use the Eclipse architecture to design flexible and extensible applications re-using a lot of already existing functionality and coding patterns inherent in Eclipse. Getting started with Eclipse RCP can be time consuming and difficult. Having a short how-to-description makes it easier to get started. Hence the following article focuses on how to get certain aspects of Eclipse RCP into work.

Integrating Flickr with your PHP website

Flickr is an image and video hosting website. Luckily enough, they provide a web service to access your photos and use them in any way you want. To get you into perspective, here’s the Flickr photoset which I am using, and here are the customised photo gallaries which I created using PHP:

* Photo gallery using Lightbox
* Photo gallery using PostCardViewer

Although I’m showing you how to integrate Flickr with Lightbox and PostCardViewer, this technique works with any photo gallery including the commercial one SlideShowPro.

System Rescue CD 1.0.3 RELEASED

SystemRescueCd is a Linux system on a bootable CD-ROM for repairing your system and recovering your data after a crash. It aims to provide an easy way to carry out admin tasks on your computer, such as creating and editing the partitions of the hard disk. It contains a lot of system utilities (parted, partimage, fstools, ...) and basic tools (editors, midnight commander, network tools). It is very easy to use: just boot the CDROM. The kernel supports most of the important file systems (ext2/ext3, reiserfs, reiser4, xfs, jfs, vfat, ntfs, iso9660), as well as network filesystems (samba and nfs).

Getting Gmail anywhere: IMAP versus POP

If you access Gmail via a phone or email client using POP, you may be frustrated by the fact that any action you take, such as reading, sorting or deleting, doesn't sync with your Gmail account. You may have read and sorted all your new mail on your phone, for example, but when you log back in to Gmail using a browser, you're presented with a full inbox of unread messages that you have to re-read and re-organize. What you may not realize is that you have another option that solves these problems: IMAP.

My Site Is Not Listed In Google. Help!

One of the most common questions webmasters ask when they release a new site is “how do I get to number one on Google?”, but what many find is that they are not even listed at all. This tutorial will take you through a number of key checks that you can do to help you get your site back on track.

Gmail Type Attachment - How to make one?

One of the most talked about thing about Gmail is probably how do they achieve making Gmail so simple, convinient, sober, fast and easy. One of the Gmail’s feature which contribute hugely in making it easier and faster for users is: Its ability to attach your files while you are writing your mail.

I have tried to come up with an exact clone for gmail attachment.

This is achieved by using an iframe which contains your server side script responsible for handling uploads. As soon as the user select a file to upload, the upload form gets submitted to upload.php, which lies in an iframe. Hence at no point does the user leaves the page and still he gets his file uploaded. Find attached below all the files you need to implement this on your server. Just unzip the file on your server, and you are ready. All the uploaded files will go in th upload folder by default. You may change that in upload.php.

Run your Linux apps on Windows without virtualization

Someone on Digg pointed to this announcement from Ulteo: “With Ulteo Virtual Desktop, you just have to run the application you need to use from the Ulteo panel and its window will show up like any other Windows application. Ulteo Virtual Desktop is free.”

Ulteo Virtual Desktop does not actually require virtualization software; it is a special Linux kernel patch called coLinux that you download and install. If you’re someone who needs to switch easily and quickly between Windows and Linux apps, it sounds promising.

Open-source Web applications, PHP vs. Java (1 of 2)

It is common knowledge that PHP does well in the open-source Web applications space. PHP has numerous representatives for most application categories, and for some it provides a clear leader, like WordPress. On the other hand, most Java counterparts have apparently failed to reach the same popularity.

Below is an overview of the existing open-source PHP and Java implementations for the following categories of applications: forum, blog, wiki and content management systems (CMS). These are among the most commonly used types of on-line software.

Linux System Information Gathering Tool

Linux Explorer ( LINUXexplo ) is a script that collects information about a linux server for support purposes, similar to the Solaris explorer ( SUNWexplo ) , Redhat's "sysreport" and SuSE's "siga" script.

Writing a kernel module for FreeBSD

FreeBSD 7.0 has already been released. If you are a real hacker, the best way to jump in and learn it is hacking together an introductory kernel module. In this article I’ll implement a very basic module that prints a message when it is loaded, and another when it is unloaded. I’ll also cover the mechanics of compiling our module using standard tools and rebuilding the stock FreeBSD kernel. Let’s do it!

OpenBSD: New Hardware Platform

Folks following source-changes@ may have noticed already: OpenBSD gained support for a new hardware platform. A little over two weeks ago I got myself a Thecus N1200. This is a little single-dist NAS box, that sets itself apart from most other devices in the market in that it has lots of extension possibilities. It has 128MB of RAM, a gigabit Ethernet port, an integrated 4-port fast Ethernet switch, two USB ports, an e-SATA port and a mini-PCI slot. My board already had a header for the serial port, so it's not necessary to solder one on yourself. Unlike the Thecus N2100 (which is ARM-based and supported by OpenBSD/armish), this little box is built around the Freescale MPC8347 System-on-Chip [SoC] platform, and has an e300 PowerPC core. So after a few days of hacking, OpenBSD/socppc was born.

ASP vs. PHP

When building web sites, ASP and PHP are very popular languages. Here's my opinion on whether ASP or PHP is best.

Both ASP and PHP are languages used to build Dynamic Web sites that can interact with Databases and exchange information. ASP (Active Server Pages) is from Microsoft and is used with IIS (Internet Information Server) that runs on Microsoft Servers. PHP (PHP: Hypertext Preprocessor) is from Rasmus Lerdorf, who originally designed this parsing language which was later modified by different people. It runs on Unix and Linux servers and it also has an NT server version.

There are a lot of differences between ASP and PHP.

Open Source BIND Alternative Launches

A group of experts on Tuesday released an open source alternative to the BIND DNS server. The new software — dubbed Unbound 1.0 — is a recursive DNS server. From its first prototype in 2004, Unbound was designed to be a faster, more secure replacement for BIND.

Ajax for Beginners

JavaScript has had the XMLHttpRequest object for a good number of years now, but it's really only started getting wide attention recently. All this attention is mostly due to some showoff web applications that make every developer who sees them think, "I want my site to do that!" But it also has to do with the spiffy, spiffy name given to it by the folks at AdaptivePath, who named this asynchronized application Ajax. Maybe you've heard of it?

Best Free Ways to Protect Your Private Files

Reuse Excel business logic with PHPExcel

In many companies, business logic resides in Excel. This business logic is sometimes created by business analysts and sometimes by business users who want to automate parts of their everyday job using Excel. This same Excel-based business logic is often copied into an application (i.e. a website) and is maintained on 2 places: if the Excel logic changes, the application should also be modified. Did you know you can use PHPExcel to take advantage of the Excel-based business logic without having to worry about duplicate business logic?

addslashes() Versus mysql_real_escape_string()

Last month, I discussed Google's XSS Vulnerability and provided an example that demonstrates it. I was hoping to highlight why character encoding consistency is important, but apparently the addslashes() versus mysql_real_escape_string() debate continues. Demonstrating Google's XSS vulnerability is pretty easy. Demonstrating an SQL injection attack that is immune to addslashes() is a bit more involved, but still pretty straightforward.

Useful in-browser development tools for PHP

While debuggers exists, there isn’t much of a tradition for using them in PHP. People have largely come to rely on injecting debugging code directly into the program, for inspecting program scope. The infamous var_dump have served for this purpose and version 4.3.0 of PHP brought us another equally useful function — debug_backtrace.

Getting Started with AJAX in jQuery

Anatomy of Security-Enhanced Linux (SELinux)

Linux® has been described as one of the most secure operating systems available, but the National Security Agency (NSA) has taken Linux to the next level with the introduction of Security-Enhanced Linux (SELinux). SELinux takes the existing GNU/Linux operating system and extends it with kernel and user-space modifications to make it bullet-proof. If you're running a 2.6 kernel today, you might be surprised to know that you're using SELinux right now! This article explores the ideas behind SELinux and how it's implemented.

Hackers Find a New Place to Hide Rootkits

Security researchers have developed a new type of malicious rootkit software that hides itself in an obscure part of a computer's microprocessor, hidden from current antivirus products.

Called a System Management Mode (SMM) rootkit, the software runs in a protected part of a computer's memory that can be locked and rendered invisible to the operating system, but which can give attackers a picture of what's happening in a computer's memory.

10 Principles Of Effective Web Design

Usability and the utility, not the visual design, determine the success or failure of a web-site. Since the visitor of the page is the only person who clicks the mouse and therefore decides everything, user-centric design has become a standard approach for successful and profit-oriented web design. After all, if users can’t use a feature, it might as well not exist.

We aren’t going to discuss the implementation details (e.g. where the search box should be placed) as it has already been done in a number of articles; instead we focus on the main principles, heuristics and approaches for effective web design — approaches which, used properly, can lead to more sophisticated design decisions and simplify the process of perceiving presented information.

MySQL 6 will be fully open source

MySQL AB, property of Sun Microsystems, reversed its decision about releasing advanced MySQL 6 features under a closed source license. Last month it was announced that the upcoming version of the widely used database server would not contain certain closed source encryption and compression backup extensions. Reportedly, those would be included only in a paid enterprise version. Now, according to a blog post at mysql.com, the decision has been reversed and MySQL will remain fully open source.

Rescuing files from lost+found

A Guide to Cryptography in PHP

In an ideal world, words like cryptography and security wouldn't even exist, but the real world is far from perfect, so software developers have to spend a good deal of time building security into applications. Cryptography is just one piece of the security puzzle, along with SSL/TLS, certificates, digital signatures, and so on. This article explains how to use PHP to implement the most common cryptographic algorithms. In addition to describing PHP's default encryption functions, you'll see how to use a wide variety of cryptographic libraries and packages.

Useful jQuery: a Compilation of jQuery Utilities

jQuery is great in many ways. You probably first heard about the framework when browsing through a showcase of beautiful “ajax” scripts and became impressed with how easy it can be used to create advanced and delightful effects. But jQuery is much more than that. After you’ve seen all the fancy slides and animations and got to know the framework, you realize that it can do much more to assist you in building advanced, content-driven web sites and applications.

Here is a hand-picked list of useful jQuery scripts and utilities, created to make your web development easier. You won’t find any fancy slides or animations in here, instead I have compiled a list of the best, most well-written and useful jQuery components on the web that I would use myself.

Building Web 2.0 Tag Clouds in PHP

Every major website seems to have a tag cloud. Users love tag clouds; they help navigate masses of content quickly and easily. When used appropriately, they help us sort filter through information stores, reduce the signal-to-noise ratio. Providing a tag cloud is also relatively painless for the server - after all, it’s just some HTML. But how do we actually build a tag cloud at application level? In this tutorial, I’ll take you through putting together a full-blown, calculated web 2.0 tag cloud in PHP.

Sun ships OpenSolaris, takes on Linux

A mere three years after starting the OpenSolaris project, Sun Microsystems today releases the first official OpenSolaris version. OpenSolaris includes the all-important Project Indiana, a project from Debian founder Ian Murdock to make OpenSolaris’ package management system more like that of Linux. OpenSolaris is based on the original Solaris kernel but includes features such as the Zettabyte File System (ZFS) which offers a range of tools including instant rollback and checks to prevent data corruption.

OpenSolaris is widely being seen as a competitor to the rival Linux open source operating system. One of the main reasons for this is the inclusion of Murdock’s Project Indiana, a software packaging system that simplifies the installation and integration of third party applications.

Do You Really Need Anti-Virus Software?

When a seasoned Windows user first migrates to Linux, the first question is always "where is the anti-virus? I have been asked this question countless time and were always given the “you are lying to me” kind of look when I told them that they don’t need anti-virus software in Linux...

Secure RSA Authentication for Linux

"So, like most folks out there, I’m concerned with security, but I love having remote access to servers so that I can work from anywhere. Opening up SSH (TCP port 22) is fairly common when administering trixbox, or any Linux server for that matter, but leaving it open also increases your chances that someone can exploit that service and compromise your server."
