How to let PowerShell/CMD list drive letters? Now, I believe that you already have known the answer. In the Windows PowerShell window, type the following command and hit Enter. Open the Run dialog box, and then type powershell in it and hit Enter. Here you can let PowerShell list drives as well. PowerShell is a command-line tool like CMD. Then you will see a list of drives on the disk, including partition/volume number, label, letter, file system, size, and status. Type the following commands in order and hit Enter after each one. Open the Command Prompt window again as we explained above. ![]() Wmic logicaldisk get deviceid, volumename, descriptionĭiskPart is a disk partition management tool that uses command lines to perform operations.

To let CMD list drives, type one of the following commands and hit Enter. Press Win + R keys to open the Run dialog box, and then type cmd in it and press Ctrl + Shift + Enter keys together to open the elevated Command Prompt window. If you want to list drives of your systems, you can use the WMIC (Windows Management Instrumentation for Management) or Diskpart command. You can input certain commands in the Command Prompt window to take corresponding actions. How to List Drives in CMDĬommand Prompt, also known as CMD, is the command-line interpreter in Windows operating system. Is there a way to list the available drives from cmd.exe? (Other than manually typing c: d: …) and seeing which ones return errors. However, many people don’t know how to list drives in Command Prompt or PowerShell, like a user from the superuser forum: When formatting a drive or copying files from a drive to another drive, you may need to use the CMD or Windows PowerShell tool to list drives.
![]() Whenever we look into a mirror or squint at sunlight glinting from a lake, we are seeing a reflection. Typically, if the surface of a transparent material is smooth, such as that of a window pane, light is transmitted partially and reflected partially. It may also be transmitted through a transparent material, such as water or glass. Light often is partially absorbed and partially reflected. Some colors of light may be absorbed and others reflected. Light can be absorbed at the surface of an opaque object. Recount and explain all the possible interactions of light with matter. Indicate that the terms right angle, perpendicular, and normal line all mean the same thing: a vertical line at a 90° angle to a flat surface. The geometry of the path of a bouncing ball is similar to that of light, but what happens at the point of impact is different at the molecular level. It is acceptable to visualize light rays as laser rays (or even science fiction depictions of ray guns).Įxplain that light bounces is a simplification. Here it means a straight line that originates from some point. It then continues in a straight line-that is, as a ray. Light may change direction when it encounters the surface of a different material (such as a mirror) or when it passes from one material to another (such as when passing from air into glass). In all these cases, light is modeled as traveling in a straight line, called a ray. Light can also arrive at an object after being reflected, such as by a mirror. Light can travel to an object through various media, such as air and glass. It can come directly from the source through empty space, such as from the Sun to Earth. There are three ways, as shown in Figure 16.2, in which light can travel from a source to another location. There are six possible ratios therefore, there are six such functions. Trigonometric functions are ratios of the lengths of two sides of a right triangle. In this chapter, we apply equations that use trigonometric functions that describe the properties of angles. In this chapter, we are focused on the first three ideas. ![]() Geometry is the study of relationships involving points, lines, angles, and shapes. The lines must be straight lines for the number to have meaning. Recall that, in geometry, angles are numbers that tell how far two straight lines are spread apart. (D) investigate behaviors of waves, including reflection, refraction, diffraction, interference, resonance, and the Doppler effect.In addition, the High School Physics Laboratory Manual addresses content in this section in the lab titled: Mirrors and Lenses, as well as the following standards: (F) describe the role of wave characteristics and behaviors in medical and industrial applications.(E) describe and predict image formation as a consequence of reflection from a plane mirror and refraction through a thin convex lens and.The student knows the characteristics and behavior of waves.

![]() ![]() Memory cards (micro SD) – A micro SD memory card allows players to back up their gameplay, to transfer saved files between devices, and even to take and save photos and videos.There are a wide range of accessories available to you if you want to upgrade your console. What Sort of Accessories Should I Get for My Switch? The use of bright neon colors makes the Joy-Con a super fun and eye catching experience. As noted above, the Joy-Con controller can either attach to the device or work as a separate unit. The Joy-Con is name of the main controller of the Switch console. Below are just a few of the popular titles you can find for Nintendo Switch: Nintendo Switch has some of the most popular and well-known games. The controller can attach to the main device for mobile play or you can connect it to a television to use it as a separate Joy-Con.Įvery console has it niche list of games that you can only find for that console. Attractive gameplay - With additions like the neon Joy-Con controllers and the ability to add on memory cards, this device has a lot going for it.For many players, this is a major plus since they no longer need two separate devices. TV connectivity - Unlike portable consoles of the past, including some of the earlier models of the Gameboy, the Switch can connect to a television or other monitor for big screen play.Its flexibility to be used as both a portable gaming device and a home console is part of the Nintendo Switch’s legendary allure. It can also be used as a TV-based console. Perfect for commutes or for travelling, the Nintendo Switch lets gamers take their current progress from their saved console games with them. Portability and flexibility - With incredibly versatile gameplay and portability, this console has taken the gaming world by storm.In a world where you can download video games on your smartphone or tablet, Nintendo is doing an amazing job at keeping up with the current trend! There are many different things that make the Switch such a popular console among gamers, including: What makes the Nintendo Switch so impressive is that it can be stationary or portable. Why Is the Nintendo Switch Such a Popular Console? On eBay, you can find a used Nintendo Switch for sale, and if you shop carefully, your used console might come fully equipped so that you can start playing. Most gamers prefer to purchase their consoles new whenever possible however, a used Nintendo Switch is a great option if the console is in good working condition. Are there benefits to purchasing a used Nintendo Switch? A third Nintendo Switch bundle that is reviewed positively by gamers is the Nintendo Switch Mario Kart 8 Bundle. It also includes a Poke Ball Plus accessory that can be used as a Switch controller and is compatible with the mobile "Pokemon Go" game. The bundle comes with a console that is customized with pictures of Pokemon characters Pikachu and Eevee on the system's dock. The Pokemon bundle is also a hit with Nintendo Switch players. ![]() ![]() This bundle comes with a console, one of the most well-known Nintendo Switch games available, and a memory card with 64 MB of memory. One Nintendo Switch bundle that has been a hit with users is the Legend of Zelda: Breath of the Wild bundle. Gamers interested in the Nintendo Switch have a number of bundles to choose from. Other games for Nintendo Switch include "Mario Tennis Aces," "Super Mario Odyssey," and "Splatoon 2." Indie games for Nintendo Switch include "Stardew Valley" and "Night in the Woods." What bundles are available with the Nintendo Switch? "Legend of Zelda: Breath of the Wild" has been available since the Nintendo Switch was first released. What games are available for Nintendo Switch?Ī number of classic games are available to play on Nintendo Switch consoles. The standard Nintendo Switch package includes: What's included with a Nintendo Switch Console? Nintendo strayed far from the beaten path with its Nintendo Switch console design. The creative design of the Switch includes a tablet body that measures 6 inches, along with detachable controllers with wireless function. But what makes the Nintendo Switch unique is that it also doubles as a handheld game system. On one hand, the Nintendo Switch console provides users with a fully functional game console for their homes. Nintendo took a bold step forward with its Nintendo Switch console. Get Your Game On With Nintendo Switch Consoles Upon returning, I sat down to see a massive rhino send Kara flying 30 feet into the air, obviously unimpressed at her carnivorous ways. ![]() Nothing was around me at the time, so I let the game continue and went to get a drink of water. So I popped up a fire and started cooking a piece of meat, acquired from an unlucky furry creature bouncing around the nearby island.Ĭooking items can take a fair while - sometimes around 30 seconds or more. In my first playthrough, I’d rowed over to a nearby island before Kara’s hunger pangs started to critically lower her stamina. The procedural generation is especially hit in miss. This Gloomharrow happily let me pepper it with arrows, which was much easier than dealing with its teleporting attack. But there’s no advice or guide on where those creatures might be, and the game’s procedural generation means you’re never really guaranteed a steady ramp of all the creatures, resources or supplies of food that you want. This is probably the most annoying element, because you need to kill certain creatures to get certain recipes. But you’ll also want to explore just to find animals and new resources, because that unlocks the recipes you’ll need to make bigger bags, better boats, and crucial exploration tools like axes and bows. You can’t leave each chapter without unlocking three towers, so naturally finding all of the islands - because the game gradually gets larger from chapter to chapter, with more procedurally generated islands - is a core part. Kara’s stamina doesn’t last long, at first, and it’s easy to quickly deplete it by sprinting too much. Once you unlock the ability to sail, you unlock the ability to basically forage from one island to another - which you’ll need, because food is an ever pressing concern. The meat and potatoes of Kara’s journey is really in three parts. You start out with a small canoe, which can be upgraded to a larger boat made of different materials. With that, Kara’s sailing journey begins. The game doesn’t provide any waypoints or general bearings, but before long you’ll find a Zelda-esque tower, which ends up granting you the ethereal equivalent of an oar that never breaks. You play as Kara, washed up on a small island following a vicious storm. What that means in practice is that it’s a game without much handholding. A product of the Satellite Reign creators 5 Lives Studios, Windbound is basically dripping in Zelda influences, most prominently Windwaker but also with a strong touch of design ethos from Breath of the Wild. ![]() Windbound has been on my radar since it launched, and the visuals make it pretty clear why. ![]() Is there a "harmless" but user-visible magic command I could practice this with (during normal operation), so I can find out how to do a REISUB next time? Lastly, a bit of a btw, I've never managed to execute an Alt-Sysrq-REISUB to force a cleaner shutdown, but that's probably because I'm on a laptop, PrintScr is only accessible via an Fn key, and I'm not sure of the exact key sequence I need. in kern.log: ? How do I get this human-readable? I imagine I could pinpoint the time it happens via log timestamps, but how do I read timestamps like e.g. Which log files can tell me what's going wrong? More or less blindly searching in the sys log viewer reminds me of needles in a haystack. ![]() How do I diagnose that? It does not happen on every shutdown, but often enough to be annoying (as it forces a diskcheck on reboot, of course). Only resolution is hard power-off (holding power key for several seconds) - neither Ctrl-Alt-Backspace (which normally works, I have it switched on in Settings) nor Ctrl-Alt-Del help, nor can I get into a text console with Ctrl-Alt-F1. I feel it happens near the end of a normal shutdown cycle, judging from time elapsed. There's just a black screen, no harddisk activity, it justs sits there. It is another thing to successfully load a Linux Kernel.Įxperimentally, I might try moving away from Ubuntu and its derivatives.Since one or two months ago, my laptop with ubuntu 12.10圆4 hangs during shutdown. It is not enough for them to check the laptop with Microsoft Windows and declare it alright now. You should describe your difficulty to them and ask them for a solution. I would take this up with the manufacturers again. Your first post in this thread says " platform idma64.0: failed to claim resource 0: " I assume this was after the laptop was returned and "mended" by the manufacturer. It says "There's a kernel bug opened about this, indicating the problem might be in the machine bios, if you are seeing a "failed to claim resource" message in your kernel log - " RTL8411B PCI Express Card Reader (rev Clevo Initial Series NL51LU is described as a Linux computer with a variety of distros being possible.

You can evaluate an arbitrary function (of one or more variables) at different arguments without re-entering the function’s definition repeatedly. The solution can be found by solving the equation B÷2+B+3B=180. Here’s an example problem: The 3 angles in a triangle are A, B, and C. Tip: Although linear equations are simple to solve in theory, letting the calculator solve it for you can still save you some algebraic manipulation. The algorithm can easily hang, fail, or give a wrong answer, so beware – it is not an automatic solver for all equations. The calculator uses a form of Newton’s method (as mentioned in the manual) to solve the equation. (However if the equation is linear, then any initial value works.) Try to give a value near an actual solution, or else solving will be slow or will fail. Give an initial guess for the variable and press the equals button. To solve an arbitrary equation of one variable:Įnter the equation on the formula line.
