Bird by Bird: Some Instructions on Writing and Life (0385480016)
Kniha - autor Anne Lamott, 272 stran, anglicky, brožovaná bez přebalu matná "Thirty years ago my older brother, who was ten years old at the time, was trying to get a report on birds written that he'd had three months to write. It was due the next day. We were out at our family cabin in Bolinas, and he was at the kitchen table close to tears, surrounded by binder paper and pencils and unopened books on birds, immobilized by the hugeness of the task ahead. Then my father sat down beside him, put his arm around my brother's shoulder, and said, 'Bird by bird, buddy. Just take it bird by bird.'"

IEEE 802.1Q VLAN Support Support for up to 256 VLANs with a VLAN ID range of 2-4093. IEEE 802.1X Access Control Authentication of network users on a per port basis prior to permitting network access. Port authentication includes RADIUS assigned VLAN, dynamic VLAN creation, guest VLAN or into an unauthenticated VLAN. Automatic Denial-of-Service Protection Monitors for malicious attacks and protects the network by blocking the attacks. Packet Storm Protection Protects against unknown unicast, broadcast and multicast storms with user-defined thresholds. RADIUS The switch supports RADIUS authentication with primary and backup server configuration. Automatic VLAN Assignment - RADIUS Assigned VLANs Automatically assigns users to the appropriate VLAN based on their identity and location. RADIUS Accounting A robust set of attributes and statistics are available for collecting information from the switch. Management VLAN ID Provides secure management access to administrators in the specified VLAN. Link Flap Prevention Minimizes the network disruption by automatically detecting and disabling ports that experience link flap events. Performance and Efficiency Energy Efficient Ethernet (EEE) Compliant with IEEE 802.3az standard requirements to save energy during periods of low data activity. Auto-Port Shut Down The switch saves power by automatically shutting down power to inactive ports. Power is restored on a port upon link detection. Energy Savings Status The switch provides an estimated cumulative energy savings due to green Ethernet features being enabled. Energy-Efficient Cooling Includes variable speed fans operating only at the speed necessary to maintain operating temperature to reduce excess noise and power consumption. Fan-Less Operation Fan-less design for 8-port models, 24- and 48-port non-PoE models, making the switches ideal for office deployments. Switching Features IEEE 802.3x Flow Control Provides a flow-throttling mechanism propagated through the network to prevent packet loss at a congested node. Spanning Tree Protocol (STP) Supports standard IEEE 802.1D STP, IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) for faster convergence, and IEEE 802.1s Multiple Spanning Tree Protocol (MSTP on local web). Loop Protection If the switch detects a loop, it disables the source port from forwarding data packets originating from the switch to avoid broadcast storms. BPDU Filtering Drops BPDU packets when STP is enabled globally but disabled on a specific port. Jumbo Frame Support Supports up to 9216 bytes frame size to improve the performance of large data transfers. IGMP Snooping v1/v2 Improves network performance through multicast filtering, instead of flooding traffic on all ports. Link Aggregation Groups together multiple ports up to a maximum of eight (8) ports per trunk automatically using Link Aggregation Control Protocol (LACP), or manually, to form a high-bandwidth connection to the network backbone that helps prevent traffic bottlenecks. The 8-port models support 4 trunks, 24-port models support 8 trunks, and 48-port models support 16 trunks. LLDP/LLDP-MED (Media Endpoint Discovery) Defines a standard extension of LLDP that stores values for parameters such as QoS and VLAN for automatic configuration of network devices such as IP phones. Address Resolution Protocol (ARP) The ARP table displays all of the IP addresses that have been resolved to MAC addresses, either dynamically or through static entry configuration. Additional Features Accessed Through Local Web-Management Interface Top Event Dashboard Provides notifications for critical events and a quick access to the latest log events. Quick Start-Up and VLAN Wizard Enables automatic configuring of the initial settings such IP address, device information, and system time. VLAN wizard can be used for setting up initial VLAN IDs and port membership. Access Control Lists (ACLs) Enables network traffic filtering by creating an ACL, adds rules and matches criteria to an ACL, and applies the ACL to permit or deny on one or more interfaces or a VLAN. Supports for 50 inbound IPv4 and MAC ACLs with up to 480 ACEs. IPv6 Host Enables switches to be managed and deployed at the IPv6 network's edge. Rate Limiting Sets and enforces per-port ingress traffic limits based on percentages or packets per second. Protected Ports Ports in a port isolation group are restricted from forwarding Layer 2 traffic between ports in that group, providing data privacy and security. SCP and TFTP File Transfer Provides different mechanisms for secure file transfer through SCP (Secure Copy Protocol) or TFTP. Dual Image Support Provide independent primary and secondary software images for backup while upgrading. User Account Management Password strength checking and aging feature provides enhanced security to user account administration to the local web management interface. Additionally, user account authentication can now be done via RADIUS to access the web-interface.' Secure Sockets Layer (SSL) Encrypts all HTTP traffic, secures access to the local browser-based management of the switch. SNMPv1, v2c, and v3 Facilitates remote management with SNMP management station that discovers and monitors the switch. Remote Monitoring (RMON) Provides advanced monitoring and reporting capabilities for statistics, history, alarms and events. RMON data is retrieved from the switch through a network management platform over SNMP.

Automatic Denial-of-Service Protection Monitors for malicious attacks and protects the network by blocking the attacks. Packet Storm Protection Protects against unknown unicast, broadcast and multicast storms with user-defined thresholds. RADIUS The switch supports RADIUS authentication with primary and backup server configuration. Automatic VLAN Assignment - RADIUS Assigned VLANs Automatically assigns users to the appropriate VLAN based on their identity and location. RADIUS Accounting A robust set of attributes and statistics are available for collecting information from the switch. Management VLAN ID Provides secure management access to administrators in the specified VLAN. Link Flap Prevention Minimizes the network disruption by automatically detecting and disabling ports that experience link flap events. Performance and Efficiency Energy Efficient Ethernet (EEE) Compliant with IEEE 802.3az standard requirements to save energy during periods of low data activity. Auto-Port Shut Down The switch saves power by automatically shutting down power to inactive ports. Power is restored on a port upon link detection. Energy Savings Status The switch provides an estimated cumulative energy savings due to green Ethernet features being enabled. Energy-Efficient Cooling Includes variable speed fans operating only at the speed necessary to maintain operating temperature to reduce excess noise and power consumption. Fan-Less Operation Fan-less design for 8-port models, 24- and 48-port non-PoE models, making the switches ideal for office deployments. Switching Features IEEE 802.3x Flow Control Provides a flow-throttling mechanism propagated through the network to prevent packet loss at a congested node. Spanning Tree Protocol (STP) Supports standard IEEE 802.1D STP, IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) for faster convergence, and IEEE 802.1s Multiple Spanning Tree Protocol (MSTP on local web). Loop Protection If the switch detects a loop, it disables the source port from forwarding data packets originating from the switch to avoid broadcast storms. BPDU Filtering Drops BPDU packets when STP is enabled globally but disabled on a specific port. Jumbo Frame Support Supports up to 9216 bytes frame size to improve the performance of large data transfers. IGMP Snooping v1/v2 Improves network performance through multicast filtering, instead of flooding traffic on all ports. Link Aggregation Groups together multiple ports up to a maximum of eight (8) ports per trunk automatically using Link Aggregation Control Protocol (LACP), or manually, to form a high-bandwidth connection to the network backbone that helps prevent traffic bottlenecks. The 8-port models support 4 trunks, 24-port models support 8 trunks, and 48-port models support 16 trunks. LLDP/LLDP-MED (Media Endpoint Discovery) Defines a standard extension of LLDP that stores values for parameters such as QoS and VLAN for automatic configuration of network devices such as IP phones. Address Resolution Protocol (ARP) The ARP table displays all of the IP addresses that have been resolved to MAC addresses, either dynamically or through static entry configuration. Additional Features Accessed Through Local Web-Management Interface Top Event Dashboard Provides notifications for critical events and a quick access to the latest log events. Quick Start-Up and VLAN Wizard Enables automatic configuring of the initial settings such IP address, device information, and system time. VLAN wizard can be used for setting up initial VLAN IDs and port membership. Access Control Lists (ACLs) Enables network traffic filtering by creating an ACL, adds rules and matches criteria to an ACL, and applies the ACL to permit or deny on one or more interfaces or a VLAN. Supports for 50 inbound IPv4 and MAC ACLs with up to 480 ACEs. IPv6 Host Enables switches to be managed and deployed at the IPv6 network's edge. Rate Limiting Sets and enforces per-port ingress traffic limits based on percentages or packets per second. Protected Ports Ports in a port isolation group are restricted from forwarding Layer 2 traffic between ports in that group, providing data privacy and security. SCP and TFTP File Transfer Provides different mechanisms for secure file transfer through SCP (Secure Copy Protocol) or TFTP. Dual Image Support Provide independent primary and secondary software images for backup while upgrading. User Account Management Password strength checking and aging feature provides enhanced security to user account administration to the local web management interface.

Hitler and Stalin: The Tyrants and the Second World War (0241979692)
Kniha - autor Laurence Rees, 528 stran, anglicky, brožovaná bez přebalu matná Two tyrants. Each responsible for the death of millions. This compelling book on Hitler and Stalin - the culmination of thirty years' work - examines the two leaders during the Second World War, when Germany and the Soviet Union fought the biggest and bloodiest war in history. Hitler's charismatic leadership may contrast with Stalin's regimented rule by fear, and his intransigence later in the war may contrast with Stalin's change in behaviour in response to events. But as bestselling historian Laurence Rees shows, at a macro level, both were prepared to create undreamt-of suffering - in Hitler's case, most infamously the Holocaust - in order to build the utopias they wanted.
