Из чего состоит дистрибутив Linux? Как он работает и почему? Что умеет, и как этими умениями управлять? Кто они такие, эти таинственные «линуксо- иды»? пингвины? Если писать программы, то про что их писать? И вообще— что на самом деле такое: «Linux», «Дистрибутив», «Сообщество», «Свободные программы» наконец? Обо всём этом и о некотором другом и написано во второй половине нашей книги. Раз уж приходится управлять таким сложным созданием, как пингвин, и тем более—таким сложным инструментом, как компьютер, без знаний не обойтись. Если вы не считаете поведение компьютера «предопределением природы», и хотите что-то изменить к лучшему, непременно стоит познакомиться с тем, что именно вы хотите изменить. По крайней мере, мы—разработчики дистрибутивов ALT Linux и участники Linux-сообщества—для себя решили начинать именно со знаний.

The first comprehensive, expert guide for end-to-end Linux application optimization Learn to choose the right tools—and use them together to solve real problems in real production environmentsSuperior application performance is more crucial than ever—and in today's complex production environments, it's tougher to ensure, too. If you use Linux, you have extraordinary advantages: complete source code access, plus an exceptional array of optimization tools. But the tools are scattered across the Internet. Many are poorly documented. And few experts know how to use them together to solve real problems. Now, one of those experts has written the definitive Linux tuning primer for every professional: Optimizing Linux® Performance.Renowned Linux benchmarking specialist Phillip Ezolt introduces each of today's most important Linux optimization tools, showing how they fit into a proven methodology for perfecting overall application performance. Using realistic examples, Ezolt shows developers how to pinpoint exact lines of source code that are impacting performance. He teaches sysadmins and application developers how to rapidly drill down to specific bottlenecks, so they can implement solutions more quickly. You'll discover how to: Identify bottlenecks even if you're not familiar with the underlying system Find and choose the right performance tools for any problem Recognize the meaning of the events you're measuring Optimize system CPU, user CPU, memory, network I/O, and disk I/O—and understand their interrelationships Fix CPU-bound, latency-sensitive, and I/O-bound applications, through case studies you can easily adapt to your own environmentInstall and use oprofile, the advanced systemwide profiler for Linux systemsIf you're new to tuning, Ezolt gives you a clear and practical introduction to all the principles and strategies you'll need. If you're migrating to Linux, you'll quickly master Linux equivalents to the tools and techniques you already know. Whatever your background or environment, this book can help you improve the performance of all your Linux applications—increasing business value and user satisfaction at the same time.

Servlets and JavaServer Pages is the first complete guide to building dynamic Java-based Web applications using the new JavaServer Pages 2.0 and Servlets 2.4. Servlets and JavaServer Pages (JSP) provide a robust solution to developing large, complex Web applications, including multiserver projects. In addition to built-in security, portability, and a Web server, they offer developers the freedom to work with any operating system that supports Javabe it Linux, Windows, OSX, or Solaris. This authoritative book begins by explaining how to set up a Servlet and JSP development environment, including a discussion of containers, Java support, and installing and configuring Tomcat. The authors then thoroughly explore servlets and JSP, including significant coverage of custom tag libraries, newly available filters, and popular servlet and JSP design patterns. Readers can then test-drive the knowledge gained by constructing a book-support Web site.

The corporate market is now embracing free, "open source" software like never before, as evidenced by the recent success of the technologies underlying LAMP (Linux, Apache, MySQL, and PHP). Each is the result of a publicly collaborative process among numerous developers who volunteer their time and energy to create better software. The truth is, however, that the overwhelming majority of free software projects fail. To help you beat the odds, O'Reilly has put together Producing Open Source Software, a guide that recommends tried and true steps to help free software developers work together toward a common goal. Not just for developers who are considering starting their own free software project, this book will also help those who want to participate in the process at any level. The book tackles this very complex topic by distilling it down into easily understandable parts. Starting with the basics of project management, it details specific tools used in free software projects, including version control, IRC, bug tracking, and Wikis. Author Karl Fogel, known for his work on CVS and Subversion, offers practical advice on how to set up and use a range of tools in combination with open mailing lists and archives. He also provides several chapters on the essentials of recruiting and motivating developers, as well as how to gain much-needed publicity for your project. While managing a team of enthusiastic developers -- most of whom you've never even met -- can be challenging, it can also be fun. Producing Open Source Software takes this into account, too, as it speaks of the sheer pleasure to be had from working with a motivated team of free software developers.

FreeBASIC is a free, 32-bit BASIC compiler for Windows (32-bit), protected-mode DOS, and Linux (x86). It began as an attempt to create a code-compatible, free alternative to Microsoft QuickBASIC, but has quickly grown into a powerful development tool, already including support for libraries such as Allegro, SDL, OpenGL, Gtk, the Windows API and many others with its default installation.

I run FreeBSD on my computers. A lot of my friends run Linux, or at least one of the distributions of it. Naturally, then, we agree that a Unix-style operating system is the right choice, but we disagree on which to use. It's been my impression that the BSD communit{y,ies}, in general, understand Linux far better than the Linux communit{y,ies} understand BSD. I have a few theories on why that is, but that's not really relevant. I think a lot of Linux people get turned off BSD because they don't really understand how and why it's put together. Thus, this rant; as a BSD person, I want to try to explain how BSD works in a way that Linux people can absorb. While there's overwhelming similarity between the operating systems in most cases, there are also a lot of differences. As you probe more into the differences, you find that they emerge from deep-seated disagreements. Some are disagreements over development methodology, some over deployment and usage, some about what's important, some about who's important, and some about which flavor of ice cream is superior. Just comparing the surface differences doesn't tell you anything; it's the deeper differences that both explain and justify why each group does things the way they do.

Much like Odysseus who had to negotiate perils between Scylla and Charybdis IT managers face daunting challenges. On one side, there is relentless pressure to cut costs. On the other lies an unending demand for innovative solutions. However, unlike Odysseus, IT managers must not simply avoid either fate: Instead, they must fulfill both quests. To meet these seemingly disparate goals, IT organizations are increasingly investigating the use of open source software for its cost-effectiveness and flexibility. However, myths about open source software persist for example, that it runs only on Linux or that it is not stable enough for demanding production environments. Dispelling those myths, leading companies such as Amazon.com and Google rely on open source software, and many more companies will make the switch in the years ahead.
