The document provides an agenda for a Mercurial training that covers installing Mercurial on SUSE Linux, basic Mercurial concepts and commands, using the Mq patch management extension tool, and common issues. It compares Mercurial to other source control management systems.
The document discusses system monitoring using OMD and check_mk. It explains that monitoring is important to manage limited server resources and service quality. Both the host and guest systems in a virtualized environment should be monitored. Key things to monitor include CPU, disk, memory, and I/O utilization. OMD with check_mk is recommended as it is a turn-key, scalable, and lightweight monitoring solution powered by Nagios. The document provides steps to install OMD on Ubuntu, enable SSL, install the check_mk agent, add a host for monitoring, perform service discovery, and activate and apply the monitoring configuration.

This document summarizes a presentation about using Mercurial for distributed version control. It discusses how Mercurial is robust and mature with support for large projects. Mercurial allows for distributed development with local repositories that can merge changes. It notes advantages over Subversion like easier branching and merging.
This document provides an overview of Mercurial, a distributed version control system. It discusses pros and cons of Mercurial compared to other version control systems like Subversion and Git. Key aspects covered include how Mercurial works with local repositories and working copies, inter-repository communication through commands like clone, pull and push. It also discusses features like tags, branches, handling large files, and workflows used at the author's game development company.
The document discusses Puppet configuration management. It provides an agenda that covers Puppet overviews, installation, configuration, the Puppet master, Puppet language basics and advanced topics, provisioning hosts, and best practices. The document includes sections on the Puppet architecture, installing and configuring the Puppet master and agents, the Puppet configuration tree and files, resources, variables, templates, and creating sample modules for SSH and NTP configuration.
Mercurial and Git are both distributed version control systems that allow developers to work offline and synchronize changes later. Some key differences are:
- Git has a steeper learning curve due to more commands and concepts, while Mercurial's model is closer to Subversion and easier to migrate to.
- Mercurial has cleaner Windows support as an official Python distribution, while Git has stronger Linux heritage and Windows support through third parties.
- Git allows discarding old branch data to optimize disk usage, while Mercurial requires keeping all revision history locally at all times.
- Both systems effectively support branching and merging, though Git can have irregular performance drops and Mercurial branching is slightly slower.

This document discusses different types of SQL joins: inner join, outer join, and cross join. It explains that inner joins return only matching records from both tables, while outer joins return all records from one table and matching records from the other table. The three types of outer joins are left, right, and full outer joins. Cross joins return all possible combinations of records between the two tables. Syntax examples and sample queries are provided to illustrate each type of join.

Do you know How many types of Joins in SQL. In this ppt presentation we are discussion about types of joins in sql server eg: INNER JOIN , SELF JOIN ,OUTER JOIN ,Right outer Join,Left outer Join,Full Outer Join,CROSS JOIN .
SQL JOINS allow data to be combined from multiple tables by performing joins between columns that share common values. There are five main types of joins: equi joins which combine rows where joined columns are equal, inner joins which return rows where there is a match in both tables, outer joins which return all rows of the left or right table even if there is no match, self joins which join a table to itself, and non-equi joins which join on columns that are not equal. Joins are useful for combining related data across tables and are implemented using conditions in the WHERE clause that compare columns from different tables.
The document discusses different types of SQL joins, including inner joins, outer joins, equi joins, non-equi joins, natural joins, cross joins, left joins, right joins, full outer joins, and self joins. It provides the syntax and examples for each type of join. It also discusses joining tables through referential integrity, where a foreign key references a primary key in another table to link the tables together.
