In one sentence, describe what the following article is about: Before you get to properly repairing your jeans, you'll first need to cut the excess threads, or frayed edges caused by the tear. Take some scissors and try to cut reasonably close; you want to get rid of any protrusions, but you also don't want to lose any material you can otherwise save. Provided you haven't lost much material, you can usually mend smaller rips without using any patches. First, turn your jeans inside out; that way, when you sew, the new seams won't be as visible. Take a sewing needle and thread, and stitch back and forth until the rip is mended. Try to make the stitches as close as possible. If it's available, try to use thread that's the same as the seam as the rest of the jeans. In many cases, this will be a white or black thread. If the rip is in a conspicuous place far away from natural seams, it's recommended you choose a colour that best fits your jeans' regular colour (usually blue or black). Once you get the rip sewn up, you can proceed to cut the extra bits off. Be sure to cut the sewing thread as close to the jean material as you can. If there are any frayed edges you didn't catch the first time around, give them a cut now. Now that you've made the repair, you'll want to seal the jeans with an iron press. This will smooth out any creases and give your pants a fresh feeling of newness.
Summary: Cut off the frayed edges. Sew up the tear. Cut all excess thread and remaining protruding material. Give your jeans a once-over with a clothes iron.

In one sentence, describe what the following article is about: If you cannot or don't want to attend an undergraduate program in computer science, you'll be pleasantly surprised at the availability of free coursework online.  For example, you can sign up for computer science related courses on Coursera.  You should also check out OpenCourseWare from the Massachusetts Institute of Technology. It is a goldmine of information for people who want to have access to computer science materials at an academic level without paying tuition. Depending on how much you already know, you can choose topics that are of interest to you and research them online or in the library.  If you are just starting out, you will want to read books, journal articles, or websites devoted to topics like computer hardware, the internet, and basic computer programming.  As you learn about these basic topics, you will find areas that seem especially interesting to you that you can investigate further. Some of these more advanced topics include security, cryptography, Turing Machines and the Halting Problem, set theory, operating systems, hardware architectures, semaphores and concurrency, computer networks and network protocols, and databases and information modeling. You can also view do an internet search for the complete list of recommended topics by Professor Matthew  Might, who teaches computing at the University of Utah. Basic computer programming is simple and easy to learn, and is a great gateway to more computer science knowledge. Plus, it comes in handy on job applications to have a working knowledge of programming, even if you don't have technical instruction under your belt.  There are a lot of different programming "languages," or systems that use unique codes. If you don't know where to start, Python is a nice language for beginners. It's intuitive and easy to learn. You can also consider C or Java. If you have tried imperative programming languages in the past, try learning functional languages such as Haskell. These are more advanced than the basic languages. Whatever approach you decide to take, you can do an internet search for articles or videos that will teach you all you need to know. In your search bar, type in the name of the programming method plus the words "beginner tutorial" (for example, "Java beginner tutorial").
Summary: Check out free online courses. Choose a topic to research. Try programming.

In one sentence, describe what the following article is about: Market share is not an end-all tool that tells you everything you must know; quite the opposite, it is more of a tool of initial inquiry. You must understand both the strengths and limitations of it as an indicator of value.  Market share is a good tool to use to compare two or more similar companies that compete against each other in a market. Though not exactly a popularity contest, it does demonstrate the extent to which one firm's product out-competes (or fails to compete against) the rest of the field. Consequently, market share can indicate likelihood of a firm's growth. If a firm has claimed increasing market share for several consecutive quarters, they have clearly figured out how to manufacture or market an especially desirable product. Companies that are losing market share may be suffering from just the opposite. As noted above, market share is a limited tool that can help you develop an initial perception of a firm. Taken by itself, it means little.  Total revenues--the sole factor used to determine market share--provide little information about the profitability to a company. If one company holds a larger portion of the market but makes substantially smaller profit (revenue minus expenses) than another, market share becomes a substantially less significant indicator of current or future success. The market share may indicate more about the market than the company you are evaluating. Some markets have been consistently dominated by a single or small group of companies, and little perceivable change has taken place over the course of many years. The power of an entrenched monopoly can be almost impossible for other companies to break, and so an examination of market share will only demonstrate that fact. However, small firms may still successfully carve out a niche for themselves, and profitability is still possible. The extent to which a company is leading or struggling in its market should impact how you perceive it.  Companies that have not shown a growth in market share in years may not be worth investing in. Firms with a growing market share are worth keeping an eye on. Unless they are poorly managed and unprofitable (which you can also determine by examining all of the publicly released financial documents of a traded company), the value of the company is likely to the rise. Firms with declining market share may be struggling. It is not the only factor that must be examined to determine this, but the company should be avoided if they also have declining profits or no new product or service offerings forthcoming.
Summary:
Understand what market share can demonstrate about a business. Comprehend the limitations of the market share indicator. Think about how market share should shape your investment strategy.
