  • Easy Slackware

    Easy Slackware

    1 Создание легкой системы на базе Slackware I - Введение Slackware пользуется заслуженной популярностью как классический linux дистрибутив, и поговорка "кто знает Red Hat тот знает только Red Hat, кто знает Slackware тот знает linux" несмотря на явный снобизм поклонников "бога Патре­ га" все же имеет под собой основания. Одним из преимуществ Slackware является возможность простого создания на ее основе практически любой системы, в том числе быстрой и легкой десктопной, о чем далее и пойдет речь. Есть дис­ трибутивы, клоны Slackware, созданные именно с этой целью, типа Аbsolute, но все же лучше создавать систему под себя, с максимальным учетом именно своих потребностей, и Slackware пожалуй как никакой другой дистрибутив подходит именно для этой цели. Легкость и быстрота системы определяется выбором WM (DM) , набором программ и оптимизацией программ и системы в целом. Первое исключает KDE, Gnome, даже новые версии XFCЕ, остается разве что LXDE, но набор программ в нем совершенно не устраивает. Оптимизация наиболее часто используемых про­ грамм и нескольких базовых системных пакетов осуществляется их сборкой из сорцов компилятором, оптимизированным именно под Ваш комп, причем каж­ дая программа конфигурируется исходя из Ваших потребностей к ее возможно­ стям. Оптимизация системы в целом осуществляется ее настройкой согласно спе­ цифическим требованиям к десктопу. Такой подход был выбран по банальной причине, возиться с gentoo нет ни­ какого желания, комп все таки создан для того чтобы им пользоваться, а не для компиляции программ, в тоже время у каждого есть минимальный набор из не­ большого количества наиболее часто используемых программ, на которые стоит потратить некоторое, не такое уж большое, время, чтобы довести их до ума. Кро­ ме того, такой подход позволяет иметь самые свежие версии наиболее часто ис­ пользуемых программ.

    De Geschiedenis Van Linux Hans Lunsing

    De geschiedenis van Linux Hans Lunsing Linus Torvalds begon in 1991 met de ontwikkeling van Linux als vervanger van het voor hem veel te dure Unix, dat hem wel als voorbeeld diende. De naam Linux is dan ook een samentrekking van zijn naam Linus en Unix. Daarom kan de vroege geschiedenis van Unix worden gezien als de voorgeschiedenis van Linux.

  • Linux Versions

    Linux Versions

    Linux Versions The Linux "product" is provided in a large number of different versions, known as "distributions," each of which retains the core kernel and GNU tools. Additionally, a variety of common tools (such as KDE, Apache, and Samba) are backed with a collection of additions and service options that meet a particular market niche. Red Hat holds the largest Linux installed base in the US, Novell SUSE Linux in Europe, and TurboLinux (based in Japan) in Asia-Pacific. Mainstream distributions--i.e. commercial applications fully supported by their vendor—have typical license and maintenance fees, just as any other commercial software applications would, while community supported distributions tend to be free to users. Table below lists the best-known Linux distributors, as well as companies that support multiple versions of Linux versions developed by others.
