Problem: Write an article based on this summary: Open the Uber app. Tap "Confirm UberPOOL. Look at the map for your designated pick-up spot. Expect additional pick-ups and drop-offs en route to your destination. Exit the car when you reach your destination. Tip for excellent service.

Answer: Type your destination into the "Where To" box at the top of the screen. From the bottom menu of car options, select the left-most choice under Economy that says, "Pool." You will see a fare-quote for UberPOOL that you can compare with that of a private ride for the same trip. Occasionally, the cost difference between a private ride and an UberPOOL ride may be very small. " A command bubble will pop up asking you to confirm your choice. Confirm it, and indicate the number of riders in your party. You can select UberPool for up to two people. You should get your own Uber and use the fare-splitting option outlined in the other method for parties greater than 2. Walk to that spot so you don't keep your fellow carpoolers waiting. You may need to walk up to a block or two from your current location. Keep your belongings tidy in the car, and allow a little extra time in your schedule to pick up other riders. You may be the first person in your car, or you may be a pick up along someone else's route. UberPOOL is able to offer you a cheaper ride option by splitting the costs between multiple riders going in the same general direction. With this in mind, your route may not be direct. Double-check that you have all of your belongings. Uber will automatically charge your portion of the fare to the preferred payment method you have on file. If your trip was great, rate your driver 5 stars and let them know what you liked about the ride.

Problem: Write an article based on this summary: Catalog your income. List your non-discretionary expenses. Determine your discretionary expenses. Look for ways to increase your income. Set an appropriate time period. Establish an emergency fund.

Answer: The first step to setting a budget is taking stock of how much money you actually have to work with. Track your income over the course of a month to get a good idea of how much money you have coming in. If you have one steady job, then you may already have a decent idea of your income. If you work irregular hours, a couple part-time jobs, as an independent contractor, or for commission, however, your income may vary from week to week. Make a list of every source of income you have. Then figure out how much money each source of income brings in. Acknowledge that the numbers might change from one month to the next, and factor that variable into your monthly budget so you'll be prepared for a short week or two. If you live with your partner and are trying to combine your assets, don't forget to add in your partner's income. Non-discretionary expenses are the things you'll always have to pay every month. These can be easier to track because of their regular frequency, though you may not be explicitly aware of how much you pay each month for these necessities. Non-discretionary expenses include things like groceries, insurance, rent/mortgage, utilities/bills, gas for your vehicle (if you have one), and/or a metro card for public transportation (if you use it). Though you probably have a decent idea of what your non-discretionary expenses are, you may not realize how much you pay for these expenses each month. Make a list of each of these expenses, and use the last few months' worth of receipts or credit card statements to estimate your average monthly bill for each expense. Everyone has variable expenses that arise from month to month. These might include shopping for clothes, recreational expenses, and entertainment expenses like movies, books, and music. These expenses are harder to predict than your fixed expenses due to their variability. It may be useful once again to review your receipts or credit card statements from the last few months to get a sense of how much you spend on clothing, recreation, and entertainment. Your non-discretionary expenses should be paid first when spending money. The discretionary expenses may be unavoidable from time to time, but you'll need to prioritize paying for non-discretionary expenses before thinking about paying for anything else. Setting a budget certainly requires cut backs and sacrifices. But a good budget might also include some extra income. Having more money coming in can help you increase your savings while still paying for your day-to-day expenses. Look for a part-time job you can do on the side. Just make sure that the hours and the type of work you do wouldn't cut into your regular/primary job. Sell old things that you don't use and don't see yourself realistically needing in the near future. Have a garage sale, or consider selling these items online (like through eBay) to maximize your potential income. If your partner or your children (assuming they're old enough and still live at home) are able to work, ask them to help contribute to your household budget. Even a little money from a part-time job could make a big difference when added to your regular savings and income. If you're trying to set a long-term ten-year budget for yourself, you might get frustrated with a lack of visible results. The same might be true if you expect to see an increase in savings after only a day or two. Instead of setting unreasonable time frames for your budget, try using a measurable span of time, like a monthly or yearly budget. You'll need a month-to-month budget to plan for regular living expenses, bills, and groceries. An annual budget can help you plan for bigger expenses that come less frequently, like paying your income taxes, buying gifts for your family during the holidays, or even an upcoming vacation. You may want to consider having two separate budgets to account for each spending variable. You can use a budget worksheet to help keep track of your expenses. This can help you balance your budget by tracking regular monthly expenses and deducting them from your average monthly income. Be willing to make adjustments to your monthly and/or yearly budgets as situations arise. That doesn't mean dipping into your savings every other weekend for a shopping spree, but it does mean factoring in possible expenses like auto repairs, medical bills, and so forth. In addition to your budget for everyday fixed expenses, you should also work to set aside some money for emergencies and other infrequent expenses. Having a financial safety net in case an emergency arises can help give you greater peace of mind and make you feel more financially stable. Make your initial savings goal relatively low and easily attainable. Try to set aside enough from each paycheck ($25 to $50 each week) to have around $250 to $500 in your emergency fund. Find ways to cut back on expenses each week so you can contribute more to your emergency fund. Save the money you would normally use for an expensive splurge (say, a big shopping trip once a month) and put that towards your savings. You can also try shopping around to save money on your insurance and deposit the difference. Once you've adjusted to taking $25 to $50 out of your paycheck each week, set up an automatic deposit with your bank or credit union. They'll automatically deduct and deposit your weekly savings sum from your paycheck, so you won't have to. After you hit your initial goal ($250 to $500 in savings), set the bar a little higher. Push yourself to double that amount by continuing to make the same sacrifices each week to meet a new goal (say, $1,000 this time). A good goal is to save one month's worth of non-discretionary expenses. Ideally, your emergency savings fund should be able to support you and pay for all of your living expenses for six to eight months, if needed. It will take a while to save up that much money, but with some planning and a few light sacrifices along the way it's attainable and well worth it.

Problem: Write an article based on this summary: Use a corneal topographer for more precise measurements. Try a Placido disc for irregular astigmatism. Use a Scheimpflug device to measure the posterior cornea.

Answer:
A topographer is a newer version of the keratometer. Your doctor will have you sit at a table and look into a bowl. This bowl's inner surface is covered in a pattern of concentric rings. A digital camera sits at the base of the bowl and charts the cornea's surface by measuring the reflected pattern in the eye. This basically creates a contour map of your eye, and it's an excellent technique for measuring irregular astigmatism. Most corneal topography tests measure 8,000 to 10,000 points on the cornea, making it the most accurate keratometry test. Other advanced ways of measuring astigmatism include autorefractors that measure refraction, and the IOLMaster that makes extensive measurements of the interior and exterior of the eye. The IOLMaster is usually used before cataract surgery. The Placido disc is an old-fashioned, hand-held device that is shaped like a giant lollipop. The disc has several sets of concentric circles painted on one side, and is used to measure the regularity of your cornea's surface. Your doctor holds the disc up to their own eye with the rings pointed towards you, and they look into your eye. Sit still and look straight ahead. The image of your cornea reflects back, and where there is irregular shape it makes the concentric rings look distorted to your doctor. This old-fashioned method can help to diagnose keratoconus, a disorder that causes irregular astigmatism due to thinning and protruding of the cornea. The shape of your posterior cornea (the back surface of the cornea) can influence the severity of your astigmatism. Keratometry can only measure the front of your cornea, but Scheimpflug imaging uses tomography to get more accurate readings of how thick your cornea is and what the back of it looks like. This method can be helpful in predicting how successful surgery may be in correcting your astigmatism.
