the guest session. A guest cannot view the home folders of other users, and by default any saved data or changed settings will be removed/reset at logout. It means that each session starts with a fresh chat program, on one workspace, and the work you are doing on a different workspace. Your music manager could be on a third workspace. Enable workspaces 1. Click the icon at the very right of the menu menu bar and uncheck Enable Wireless. What do WEP and WPA mean? WEP and WPA are ways of encrypting data on wireless networks. Why does my wireless network keep disconnecting? You might have low signal

If this is not the first time an operating system has been installed storage configuration screen will install Ubuntu onto the selected disk, replacing any partitions or data already there. You can choose whether or not to set up LVM, and if you do, whether or not to encrypt

packets: It breaks the limitation of the TCP framework. This model adds an EDT timestamp to each data packet based on the scheduling policy, avoiding the delays caused by large queue buffers and bringing improvement in TCP performance. 9. MultiPath TCP: It improves performance and reliability in mobile and data scenarios. MultiPath TCP supports concurrent transmission of multiple substreams in load balancing sequential write performance of large solid-state drive (SSD) blocks and the performance of the double data rate (DDR) persistent memory. 12. io_uring: This is a new asynchronous I/O framework that supports

IT a fast reaction to server problems. Zabbix offers excellent reporting and data visualization features based on the stored data. This makes Zabbix ideal for capacity planning. Zabbix supports both polling single package. Data gathering • availability and performance checks • support for SNMP (both trapping and polling), IPMI, JMX, VMware monitoring • custom checks • gathering desired data at custom intervals

small-medium-large as units for assigning story points. Over time, as the teams accumulate performance data, this iterative and incremental4 process improves accuracy in allocating points. Point values are success, as many variables that affect success lie outside the control of the government program manager and his team. In the government context, Agile represents a good development approach when customizing team responsible for execution. The release team includes a core team composed of the project manager, product owner, tester, and system engineer, and a development team led by a scrum master (scrum
