Almost any sport requires you to coordinate between your eyes and your hands. Pick up a sport that's interesting to you, and make it part of your regular weekly routine. Set a goal of play for an hour 3-4 times a week. Look into intramural teams or classes in your area to help keep your practice consistent and make the process more fun. Sports that involve bats or sticks such as baseball, softball, hockey, and lacrosse are all common recommendations for those looking to improve their coordination. You could also consider getting a badminton net, volleyball net, basketball hoop, or ping pong table for your home if you want to practice on your own time. Boxing and many forms of martial arts are also great to help improve eye-hand coordination. Look into classes in your area for boxing, mixed martial arts (MMA), taekwondo, karate, krav maga, or any other form of martial arts that interests you. Video games require both motor skills and visual perception to execute gameplay. Play a game that requires precision timing, a sensitive touch, and/or great attention to detail, and you may find it helps improve your overall eye-hand coordination. Action games like Call of Duty or Assassin's Creed can be particularly useful for this purpose. Try different types of games, if you have the systems available. Console games, PC games, and VR games will all challenge you in different ways. Learning to juggle is a common activity recommended for people trying to improve their coordination. Start by learning to juggle with 2 balls, then move your way up to three. Consult online tutorials and videos to help get you started, since juggling is often better understood visually. Don't get disheartened if you're not a great juggler when you first start. This is an activity that takes a lot of time to master. Keep practicing and you will slowly start to see benefits with your overall hand-eye coordination. This requires picking up specific pieces to analyze which ones fit together, using and improving both hand-eye coordination and reasoning skills. Challenge yourself even more with a 3D jigsaw puzzle, a Lego sculpture, or another building toy that allows you to think in 3D. This creative activity helps you learn to visually control your hands and fingers by working in the lines on the page. Look for a coloring book that will challenge you with fine lines and details throughout the page. Adult coloring books are gaining popularity, and are readily available at many craft stores and bookstores. Many people find these relaxing as well as a good coordination training tool.

This is the platform you'll be using to code your new operating system. It's a matter of personal preference, but most people either use Windows or a flavor of UNIX. If you're using Windows, it's a good idea to install a UNIX environment like Cygwin or MinGW. You'll generally want to make sure whatever environment you're using includes the following: GCC (the Gnu compiler). If you're using Windows, you can install it in Cygwin or MinGW. Binutils is a collection of tools used for manipulating object files. Again, if you're using Windows, you can install it in Cygwin. A good text editor. Vim and emacs are commonly used in UNIX environments. Windows users can use Notepad, or check out Notepad++ for a multi-tab upgrade. Perl and/or Python. One or both are recommended for string manipulation. Writing an operating system means you'll likely be creating hundreds (or thousands!) of lines of code. When you're working on revisions, this can get confusing. Some options to check out are CVS, Mercurial, and Subversion. If you don't want to create your own, you can use an existing one like Grand Unified Bootloader (GRUB). If you do feel daring enough to code a bootloader, check out Rolling Your Own Bootloader on OSDev.org. The kernel is the core of your operating system, providing an interface between the user and the computer hardware. There are monolithic kernels and micro kernels. Monolithic kernels implement all the services in the kernel, while microkernels have a small kernel combined with user daemons implementing services. In general, monolithic kernels are faster, but microkernels have better fault isolation and reliability. Begin with small things such as displaying text and interrupts before moving on to things such as memory management and multitasking. You can also try making a simple 16-bit Operating System, instead of taking a big leap. You will not have a full system in two weeks. Start with an OS that boots, then move on to the cool stuff. Rather than rebooting your computer each time you make changes or having to transfer the files from your development computer to your test machine, use a virtual machine application. VMWare is a common option that works with both Windows and Linux, and so is Bochs. Check for potential deadlocks and other bugs and repair them as needed. " You can do this by uploading your tested code to your public repository. This will allow people to test your operating system and report back on any issues they run into. There's an entire community of operating system developers congregating on various forums, including /r/osdev on Reddit and the Software Engineering Stack Exchange. One you've gotten a grasp on developing a basic operating system, read existing posts to see what kind of things come up during the development process.

The most successful athletes are defined by their ability to accommodate for a wide range of techniques. In a competitive environment, you can't depend on the other team to use one kind of shot. If you feel like you've mastered certain blocks but other players are still getting shots past you, it is likely you haven't taken all possible shots into account yet. Here are some common shots to look out for: A jump shot is the most common shot. To gain height, offensive players will jump in the air and throw the ball towards the net. A slam dunk is the most efficient shot in basketball. This is where an offensive player runs directly up the court, jumps up, and delivers it directly into the net. A fadeaway is an advanced shot where the offensive player will lean away from the net as he throws it in. This is done to avert the efforts of blocking players. It can be resisted by putting your arms in the predicted path of the basketball. A faked shot is where an offensive player lines up a shot but doesn't actually throw the ball. This is done for psychological reasons of tricking up the opposing team. Slam dunks are considered very risky shots, as it's difficult to get a proper block without incurring a foul call. If you do attempt to block a slam dunk, get in between the net and the other player and jump directly up, aiming your hand in the path of the ball. A fadeaway shot is where a shooting player will hop backwards as he throws the ball towards the hoop. This tactic is specifically geared to trick up a blocking player. To maximize your chances of blocking a fadeaway, jump up between the ball and the net and extend your hands towards the ball. Don't swing your arms unnecessarily around as you're blocking. This will incur a foul call. A significant part of blocking shots in basketball involves the proper use of jumping. Jumping is a muscle-based exercise, but it's not often seen as a primary workout focus for many players. Practice doing sets of vertical jumps, attempting to get as much force off the ground as you can. Next, add on to this exercise by holding barbells in each hand and jumping with them. This will increase the pressure on your legs, making them better-suited for jumping blocks when you play competitively.
