In one sentence, describe what the following article is about: Use your foot to push down on the lever near the rear wheels. While the lever is in its lowest position, it should prevent the wheels from moving. On some stroller models, the front wheels may also have a locking mechanism to prevent them from swiveling. First, push the stroller a few paces forward to put the wheels in the forward position. Then, look for a small lever between the front wheels. If present, it may need to be pushed up or down, depending on the model, to lock the wheels in position. Tug gently on the canopy, if opened, to pull it back into folded position. Push the seat backward to recline it as far as it will go. On some models, you may need to undo latches on the side of the seat before this is possible. Check the right and left sides of the stroller for a small handle, somewhere near the seat base or wheels. Some models simply fold when this handle is tugged in a particular direction, while others require a button in the center of the handle to be pushed and held down as you fold. You should now be able to fold the stroller together simply by pushing the back and seat together. Grip the lower handle if there is one. If necessary, tug the lower frame near the wheels to start the folding, then withdraw your hand from that area to avoid pinching your fingers in the folding frame. Finish pushing from the top handle and the seat base.
Summary: Set the brakes. Lock the front wheels. Collapse the canopy. Recline the seat backward. Look for a low handle. Fold the stroller together.

In the U.S., it is generally legal to use a hidden camera to record footage without a person's consent--provided that you are filming in public or within your own home. Many states have passed laws against filming people in spaces where they have a reasonable expectation of privacy, such as bathrooms or personal bedrooms.  It is generally legal to use a hidden camera in the workplace, as long your filming pertains to a business concern. Don't film someone at work without their consent in order to settle a personal dispute--unless you're ready to risk legal consequences.  Laws vary between states and countries. Research the laws for your area before you record audio or video of anyone without their express consent. If you are planning to distribute the footage, sell the footage, or use it in court, then it is extremely important that you follow the law. If you are only planning to use the footage for personal entertainment purposes, you may not need to worry so much. Run a web search for "free webcam recording program" and install the software onto your computer. You may be able to use Windows Movie Maker or iVideo, if these are already installed on your computer. Search the Start menu (bottom left-hand corner of the Windows desktop) to figure out whether you have a program installed. When you leave the room, or when you are ready to start recording, boot up the recording software and click "Record". Cover up the USB cord with something so that it isn't obviously running to the hidden camera. Books, papers, or a jacket will do--anything that looks natural. Be subtle; only do this if you typically keep a webcam next to your computer.  Keep in mind that while this may be a more straightforward approach, the snooper may be more suspicious if they notice a camera point at them--even if they don't think that it's turned on. Be sure to turn off, cover, or disable the LED light that shows that your webcam is running. The "recording" light may tip off a snooper that they are being filmed. If the screen is open and the snooper can see the webcam feed, they will know that they are being recorded. You have to be sneaky to catch a sneak.  If you own a desktop computer, you should be able to turn off the monitor and leave the computer tower running. If you own a laptop, you may be able to put the screen to sleep while the recording program runs. You may also consider folding the screen down until the laptop is almost--but not quite--closed. The computer will look like it's off, but it will still be running. Leave the camera running when you think that it will capture what it needs to capture. If you're not sure, leave it on as often as possible. If time goes on and you don't capture anything incriminating, reconsider the situation. Was the snooping a one-time thing? Has the snooper found a way to sneak around your camera?

One-sentence summary -- Be aware of the law. Download a webcam recording program. Hook the USB cord up to your computer. If you already own a webcam, consider simply using your existing camera to take the footage. Make sure to turn off or darken your screen. Keep recording until you get the footage you need.

Q: It might seem counterintuitive, but developers swear that the way to go is to write code to pass a unit test, rather than using unit tests to see if code will work. This can be the approach to take if you haven’t actually begun to write your code, or if you don’t have much yet. Be goal-oriented: write your unit tests to check if code will do what is expected, then write the code, then test it. Writing the tests first encourages you to write just enough code to make the program do what it needs to, without inadvertently including unnecessary or bad code. If you’re well on your way with the writing of your program, you can still make use of unit tests. Just draw on the map you made of your program to break it down into individual units. Run the tests using the AAA approach, and adjust your code as needed based on the test results. One of the hardest things about using the unit test approach in program development is that you must plan carefully to have code that can actually be tested. If your program is full of elements that you can’t actually test, then you won’t be able to use the unit test method to verify that your program will work as expected. Keep this in mind as you write code for your program. For example, avoid things like hidden inputs and non-deterministic factors in your program’s code.
A: Write the test before you write the code. Come up with unit tests as you write code, if you need to. Write testable code.

Problem: Article: Set it to 400 degrees Fahrenheit (200 degrees Celsius). You can skip straight to roasting, but parboiling the parsnips first will help prevent dry or chewy parsnips. To parboil, put whole or halved parsnips in salted, boiling water and cook for 8 minutes or until slightly tender. Rinse with cold water until they stop steaming, then pat dry.  This is more important for mature parsnips more than 1 inch (2.5 cm) in diameter, which have a woody, fibrous core. If you do not plan on parboiling, cut out the cores from large parsnips and discard them.  Parboiling the peel will loosen it and allow you to slide it off by hand. If you did not parboil, leave the peel intact, since the best flavor is right underneath it. The parsnips are ready when they are browned or lightly caramelized in a few places, but not yet shriveled. This typically takes 45 minutes, or as little as 20 minutes if you parboiled the vegetables first. Check on them early, since cooking time varies with the size of your pieces. For more even browning, check on the parsnips after 10 or 20 minutes and flip pieces that are sticking to the pan. Like potatoes, parsnips tend to have a dry texture that improves when paired with butter, cream, yogurt, or crème fraîche. Optionally, toss with fresh herbs that match your seasonings, such as chopped cilantro to go with coriander and cumin. You can keep the dish warm in an oven on a low setting until the rest of your dinner is prepared.
Summary:
Preheat your oven. Parboil if you prefer a soft texture. Roast until lightly browned. Serve immediately.
