According to an old saying, the military always fights the last war. In World War I, both sides were relying on tactics that were obsoleted by the invention of the machine gun. In World War II, the French didn’t factor in the development of the bomber. In Vietnam, the American military tried to apply blitzkrieg-like tactics to a guerilla war. The Free Software community has a similar problem. Recent years have all begun with people asking, "Is this the year of the open source desktop?" (Or sometimes the Linux desktop if the journalist in question doesn’t actually know what Linux is.) The correct answer to this question is "who cares?"

OpenBSD is quite possibly the most secure operating system on the planet. Every step of the development process focuses on building a secure, open, and free platform. UNIX® and Linux® administrators take note: Without realizing it, you probably use tools ported from OpenBSD every day. Maybe it's time to give the whole operating system a closer look.

The really interesting thing I want you to notice, here, is that as soon as you think of map and reduce as functions that everybody can use, and they use them, you only have to get one supergenius to write the hard code to run map and reduce on a global massively parallel array of computers, and all the old code that used to work fine when you just ran a loop still works only it's a zillion times faster which means it can be used to tackle huge problems in an instant.

So rather than react as some have done with a knee-jerk “no it’s not!”, I propose to accept the label and see where that insight takes us. Maybe there is something communist about free software? I think we will see, however, that the idea behind free software is far more radical: no less “communist” than “capitalist”, but no more so, either.

The 55 Cancri system involves three gas giant planets and another world that could be icy or rocky and is about the size of Neptune. The setup is 41 light-years from Earth and about 4.7 billion years old, comparable to our Sun.

Work could begin in the first week of September on the European Space Agency/Russian Federal Space Agency (RFSA) crew transport system programme, once financial contributions and legal documents are agreed by ESA member states this month.

Let's face it. Google pretty much owns the Internet landscape. Unless something truly unexpected happens within the web community, I see no real indicator that they'll lose their market share anytime soon. This also opens them up to other online opportunities should they decide to pursue them. One such opportunity is believed to be the much famed idea of a Google OS. The rumors have been floating around back and forth for awhile now and many people believe that it's simply a matter of time. Well I'm here to tell you that this is never going to happen; at least not in a form that we might expect to see, that is.

This article looks at five common Web application attacks, primarily for PHP applications, and then presents a case study of a vulnerable Website that was found through Google and easily exploited. Each of the attacks we'll cover are part of a wide field of study, and readers are advised to follow the references listed in each section for further reading. It is important for Web developers and administrators to have a thorough knowledge of these attacks. It should also be noted that that Web applications can be subjected to many more attacks than just those listed here.

In the practice of security we have accumulated a number of “rules of thumb” that many people accept without careful consideration. Some of these get included in policies, and thus may get propagated to environments they were not meant to address. It is also the case that as technology changes, the underlying (and unstated) assumptions underlying these bits of conventional wisdom also change. The result is a stale policy that may no longer be effective…or possibly even dangerous.

In this article, I'll examine the work of the World Wide Web Consortium (W3C) in creating the next-generation version of their XHTML specification, and also their response to the demand for "rich client" behavior exemplified by Ajax applications.

This page is going to assume you’ve done a little reading and absorbed some paranioa about the issue of character sets and character encoding in web applications. If you haven’t, try here; “When I discovered that the popular web development tool PHP has almost complete ignorance of character encoding issues, blithely using 8 bits for characters, making it darn near impossible to develop good international web applications, I thought, enough is enough.” “Darn near impossible” is perhaps too extreme but, certainly in PHP, if you simply “accept the defaults” you probably will end up with all kinds of strange characters and question marks the moment anyone outside the US or Western Europe submits some content to your site This page won’t rehash existing discussions suffice to say you should be thinking in terms of Unicode, the grand unified solution to all character issues and, in particular, UTF-8, a specific encoding of Unicode and the best solution for PHP applications.

Pure CSS-based layouts have come a long way but they still have shortcomings [2] that fail to address certain design goals without compromising the true separation of content and presentation.

JavaScript’s increasing popularity throughout the web makes it more important than ever to make sure our client side code is implemented with a nice mix of stability, speed, and reusability. One of the best ways for accomplishing this is to use a simple library and syntax to use as a foundation for every project. Thankfully, Sam Stephenson created an amazing library of functions that we can rely on called Prototype.js to ease our JavaScript development practices.

Can CSS be used for serious print jobs? To find out, we decided to take the ultimate challenge: to produce the next edition of our book directly from HTML and CSS files.

In recent times, an unprecedented amount of Web content has begun to be generated through web logs, wikis and other social tools thanks to lower technology and cost barriers. A new host of content creators is emerging, often individuals with the will to participate in discussions and share their ideas with like-minded people. This is to say that this increasing amount of varied, valuable content is generated by non-trained, non-expert information professionals: they are at the same time users and producers of information.

Kliper is also being designed to operate completely autonomously, without the need for pilot control. "It's got to be capable of automatic flight," Thirkettle says. Some on the team hope Kliper would be able to travel to the Moon, "but I think there's a little bit of science fiction in that", he says.

A breakthrough by a team of British, US and French scientists will help protect astronauts, spacecraft and satellites from radiation hazards experienced in space.

Kliper (Клипер, often also referred to as Clipper) is a spacecraft proposed in 2004 by Russian rocket and space company RKK Energia. Designed primarily to replace the Soyuz spacecraft, it is a reusable space plane with small wings that glides into the atmosphere at an angle that produces much less acceleration on the human occupants than the current Soyuz. The craft can carry up to six people and can be used for ferry services between earth and the International Space Station, but is also planned to be the crew module for further trips to the Moon and Mars. The primary focus for its development was to reduce costs for manned space flights by using the reusable spaceship approach.

This is a detailed description about the steps to be taken to setup a SUSE 9.3 based server that offers all services needed by ISPs and hosters (web server (SSL-capable), mail server (with SMTP-AUTH and TLS!), DNS server, FTP server, MySQL server, POP3/IMAP, Quota, Firewall, etc.). In addition to that I will show how to use Debian's package manager apt on an rpm-based system because it takes care of package dependencies automagically which can save a lot of trouble.
