Summarize the following:
The use case explains the goal of the technology or process, not how the technology functions. In other words, a use case about logging in to software does not include how the code must be written or how the technological components are connected. It simply focuses on what the user needs to do and how the software responds. Get the level of detail right. For example, if writing a use case about implementing technology, don't exclude details about how the software responds to users. Alternatively, adding too much detail about how the software functions reads more like system design implementation than a use case. Use cases do not need to include complex flow charts or visual diagrams that explain the process. Simple flow charts can often be used to clarify information. However, the use case should be largely word-based. The style of writing should be very simple so that others can read and comprehend it without specific training. Writing a good use case helps you learn exactly how a piece of software or business process works. It educates you and the reader about the correct use of applicable vocabulary. This way, you know you are not using technological terms incorrectly or gratuitously. You can learn to discuss technology and business processes in a way that is useful and valuable to others in the business community.

summary: Capture what the technology or business process does. Keep the use case primarily textual. Learn the most relevant details.

Hold the fishing rod with your casting hand at the base of the reel. Leave about 12 inches (approximately 30 cm) of line hanging between your bait hook and the tip of the rod. Grab the line with your index finger and keep it taut. Make sure that there is nothing behind you for the line to catch onto (e.g., a tree or other person). Aim the line at the line towards the spot in the water you want it to land in, then pull it backwards. Cast it out and release your index finger from the line. After casting your rod, wait several seconds for the jig hook to reach the bottom. If the bait is heavy enough you may feel the spoon hit the bottom. Note that lightweight jig hooks will take longer to sink. Make boisterous vertical motions with your rod by flicking your wrist and popping your fishing rod tip up a short distance. Allow the jig hook to sink back to the bottom. Repeat this process to get the attention of larger fish looking for food. Vary your movements by jigging the rod up and down and side-to-side. Cast your line out into the water. Hold your fishing rod at a 60 degree angle and slowly reel the line in. This motion will cause the jig to flow through the water smoothly, appearing to swim.

summary: Set up your fishing rod. Cast out your line. Wait for your jig hook to hit the bottom of the body of water. Snap and pop the line. Use the "swimming" technique.

Summarize the following:
In order to prevent the murderer from finding you, barricade the main entry to your hiding area as best as you can. Ideally, there should be a sturdy lock on the inside of the door, and the door should open out so the murderer can't kick it down. You may also want to barricade the door with additional obstacles, like heavy pieces of furniture. If your door swings in, it's especially important to barricade it with heavy objects, as the murderer may be able to kick it in. While it's good to be able to keep the murderer out, it's also important to think about how you will escape if the murderer does manage to get in. A hiding spot with two exits (like a door and a window) is ideal. If you're outside, you may not be able to barricade yourself, but you should still look for a secluded location that you will easily be able to escape from if necessary. Once you find a hiding spot, you need to do whatever you can to make sure that the murderer does not locate you, which means staying as quiet as possible. If you are with other people, avoid talking to each other. You should also make sure your cell phone is silenced. The murderer may still be able to hear your phone if it is on vibrate! Resist the urge to yell to the murderer that you have contacted the police. Make it more difficult for the murderer to see the area you are hiding in by turning off all of the lights and closing all of the windows and blinds. Make the area look as unoccupied as possible. You should also turn off any other sources of light, such as computer monitors. While calling for help should be your priority, beware of the light from your cell phone. If the murderer is right outside your door, he may be able to see it. If you are hiding with other people, spread out as much as you can in your hiding spot. This will increase each individual's chances of survival if the murderer gets into your hiding spot. Make sure everyone stays away from windows, as these are often the most vulnerable part of the room. If you want a great hiding spot within your barricaded room, find a piece of furniture or a similar item that you can use to hide in. The less obvious the hiding spot, the better. You may want to hide behind the (floor-length) curtains, behind a desk, or behind the clothes in a closet You could try hiding under the bed, under a pile of laundry, or under a blanket. You could also consider hiding inside a cupboard, in the washing machine, or inside a large box. If you are outside, you may want to hide behind a bush, under a car, in a trash can, or under a porch. If you are not able to run away or find a place to hide, playing dead may be an option. This will only work if the murderer has already killed a lot of victims. Simply lie down among the victims and hope that the murderer doesn't realize that they haven't killed you. Lying face down or in an obscured location may help, as the murderer will not be able to see if you move a little bit. As soon as it is safe to do so, call emergency services for help. If you have a cell phone with you, you might be able to do this while you are hiding, as long as you don't think that making a call will give away your location to the murderer. Stay on the line with the operator until the police get there. The operator will want to know as many details about the situation as possible, such as your location, the number of victims, and what kinds of weapons the murderer has. When the police get there, follow their instructions and keep your hands visible at all times so that they know you are not a threat. If calling the police is too loud, text someone who is not at the location about your situation and ask them to call the police for you. Consider texting this to several people, just in case someone doesn't see the text. In some areas, it's also possible to text 9-1-1.
summary: Choose a hiding place that can be barricaded. Stay quiet. Obscure your location. Avoid huddling together. Hide in, behind, or under something. Hide in plain sight if necessary. Call for help.
