What real words are actually valid CSS HEX colours? Parsing an English dictionary for entries containing only the letters ABCDEF (and 0157 disguised as OIST) and limiting the result to words of exactly 6 or 3 letters length (#FFFFFF or #FFF) gives us some interesting results.

tutorial windows sysadmin windows server 2008When creating an RRD database we'll need to specify a couple things, namely one or more Data Sources and one or more Round Robin Archives. The data source (DS) defines what type of data is accepted and some boundaries on what constitutes good data. The round robin archives (RRA) can almost be thought of as views, it defines the different ways we can store and retrieve data.
tutorial programming rrdtoolBy making the primary NTP server flag 0x9, we made it Client 0x08 + SpecialInterval 0x01 and as for the second NTP time server. By making the secondary NTP peer flag 0xa, we made it 0x08 Client + 0x02 UseAsFallbackOnly. On initial sync during service startup the polling interval time is zero which will not match the special polling interval that our 0x01 flag requires. This being the case w32time will use the Fallback server as its primary choice until the special polling interval arrives then it will use the intended primary server.

windows sysadmin securityRRDtool refers to Round Robin Database tool. Round robin is a technique that works with a fixed amount of data, and a pointer to the current element. Think of a circle with some dots plotted on the edge. These dots are the places where data can be stored. Draw an arrow from the center of the circle to one of the dots; this is the pointer. When the current data is read or written, the pointer moves to the next element. As we are on a circle there is neither a beginning nor an end, you can go on and on and on. After a while, all the available places will be used and the process automatically reuses old locations.
tutorial sysadmin networking rrdtoolRRDtool is a graphing utility made by Tobi Oetiker that takes data sets you collect and graphs them. RRDtool (acronym for round-robin database tool) correlates time-series data like network bandwidth, temperatures, CPU load or any other data type. Data is stored in a round-robin database (circular buffer) which allows the system storage footprint to remain constant over time. The database will always have the same amount of data points throughout its lifetime. When new data comes in the oldest data set is removed.

Not all API actions defined by a service can be used in an IAM policy, and a service might define some permissions that don't directly correspond to an API action. Use this list to determine which actions can be used as permissions in an IAM policy.

Cumulative updates with new security fixes arrive on the second Tuesday of each month ("patch Tuesday"). Cumulative updates with new quality fixes arrive on the fourth Tuesday of each month. Windows Server 2016 updates first arrive as "optional" updates, but they later become "recommended" updates after two weeks.
