Puppet manifests are declarative, as are SQL queries and makefiles. This is where you define the desired state, and the tool conforms the system to the model of your desired state. Then there's declarative, also known as functional. You're creating a list of things to do, and the system does them. Imperative, also known as procedural, is an approach where the commands to produce a desired state are defined and executed. There are two common approaches to configuration management code. But if your shop uses something else, ask a developer to show you the ropes, it won't take long to get up and running. We'll use Git in this course, and there's plenty of simple online tutorials that will teach Git. If you're not experienced with it, it's easy. First, you'll want to use source control. So, for folks that aren't developers, what does a normal code flow look like? Here's an illustration of a continuous delivery flow, where a code gets checked in, goes through successive levels of testing, and finally gets released. The task ahead is to realize that these are code, and we'll apply coding best practices to them. Maybe it's shell scripts, apache config files, build definitions or OS files. Don't worry, you don't have to learn Java to do DevOps. It is best to leave artifacts where they are discovered and to report the find to the Florida Department of State, Division of Historical Resources or a professional archeologist.- In this video, we're going to talk about the pipeline you'll set up for your systems to take them from code to artifacts to running systems. It is currently illegal to remove artifacts from state land. As a result, it is much more common to find stone and metal tools which can withstand Florida’s harsh climate. Florida’s semi-tropical climate and plentiful rainfall are not conducive to preserving artifacts that are made from these materials. Some uncommon artifacts include bone tools, wood and fabric. Some commonly encountered artifacts in Florida include spear points, arrowheads, pottery sherds and iron tools that were brought to Florida by Europeans. Florida has a wealth of historic and prehistoric archeological sites which are defined by the artifacts that are present. The term is generally applied to items that are very old (hundreds to thousands of years). Artifacts are objects that are made or used by humans.

To learn more about FGS fossil collections, see our Fossil Collections page. Fossils are also useful in correlating and determining the age of rock units. Based on the types of plants and animals present in a rock unit, scientists can often determine what ancient climates were like as well. Fossils provide important information about the past life on earth. Other fossils such as seashells are preserved with little change. Petrification occurs when minerals replace the organic material that originally comprised the organism. Some fossils, such as wood, bones, and teeth, are petrified, or turned to stone. Because soft flesh does not preserve well, many fossils represent only the hard parts of the original animal, such as the shells of molluscs or the bones of land animals like the mastodon. They also come in many sizes, ranging from less than 1/100th of a millimeter to greater than tens of meters. Fossils come in many forms - seashells, animal bones, leaf impressions, wood, even animal burrows or footprints preserved in rock. A scientist who studies fossils is called a paleontologist. A fossil is any trace of past life that lived prior to historic times.
