X11 – cryptocurrency mining algorithm with 11 hashing rounds


Bike features

Here are the main features of the Honda X11:

  • thoughtful design down to the smallest detail;
  • excellent road grip;
  • a kind of wind protection.

It would take a long time to list the advantages of the bike, but in short, Honda definitely tried to make the perfect naked bike. It’s too early to judge whether they succeeded. Now, if in twenty years the motorcycle still remains relevant, this question can be answered in the affirmative.

Window Manager

Window Manager Task

The X server takes responsibility only for issuing an area for input/output to the X application and managing the focus of the window, but does not engage in any manipulations to change this window: moving, resizing, minimizing, etc. Methodius has already observed the X server , to which exactly two clients are connected, whose windows overlap: two black and white windows on top of each other, and they cannot be pulled apart into the corners or compressed. The X server can very cleverly manipulate windows, but it never does anything itself, it waits for a command from the user program. And what program would want to independently monitor window overlap, focus, resize, move, and the like? After all, the main task of the program may be completely different...

The answer is obvious: this should be done by a program whose main task is to track overlap, resize, move, turn into an icon, and so on. In combination, the same program will draw all sorts of beautiful things on the windows: frames, headers, buttons and control menus - in a word, do everything that is needed to organize the window management logic. To do this, you will also have to handle almost all events transmitted from input devices, and numerous “hints” from applications regarding how they want their own windows to look. This X application is called a window manager .

Not to be confused with screen manager , which does something completely different: it replaces the login utility.

window manager A program whose main function is to provide manipulations with windows: moving, resizing, minimizing, etc.

Thanks to the standard X11 protocol, there are so many window managers for the X Window System that it is simply impossible to list them all. They all differ in appearance and the range of possibilities for manipulating windows: from the simplest (the frame around the window allows you to move it, resize it and raise it from the depths; in fact, everything) to the very sophisticated (virtual screens, animated translucent menus, toolbars, fancy decorations on the windows; the windows themselves crawl across the screens, tumble, dissolve like morning fog; all this clangs, squeaks and speaks in a pleasant female voice). When Methodius ran the startx command for the first time, the wm-select utility was launched, which prompted him to choose which of the window managers installed on his system to launch.

Choosing a window manager to suit your taste is a very difficult and thoughtful task. We advise you to simply observe the measure, in accordance with what you are using the window system for: an abundance of bright decorations distracts from the work (and what if they move, in addition?), and too strict minimalism complicates it. Keep in mind that the more fanciful and diverse the capabilities of a window guide, the more difficult it will be to completely customize it just for you. Most likely, you will simply agree to use already configured - commonly used - features without bringing them to perfection.

Working with Windows

It is absolutely not necessary to start your X11 session by starting the window manager; you can start it at any time. For example, Methodius can connect any window manager to the X server he has already launched, launching it all from the same virtual console. For example, to start WindowMaker, just run the wmaker command.

With the launch of the window manager, the X server screen noticeably changed: the monochrome background was replaced by an image, square buttons appeared in the corners, and a frame appeared around the xterm window with the window name and buttons. This frame is the “controls” of the window, the so-called window primitives (their proper name is “widgets” - short for “window gadgets”, “window gadgets”). “Grabping” the frame with the mouse, Methodius changed the size of the window, and by clicking the right mouse button on the window title, he saw a menu consisting of a list of operations that can be performed on this window. All these capabilities are provided by the WindowMaker window manager.

Facilities

However, in addition to its main function - window operations - many window managers have a lot of other techniques to simplify the user's work and increase visibility. The most important of these conveniences are buttons for launching common tasks: clicking a button replaces executing a command in a terminal emulator. The command can be long or forgotten, but pressing one time and the button is visible all the time - this is convenient for familiar everyday actions. For example, in the upper right corner of the WindowMaker screen there is a button with a monitor image - to launch xterm. The second most important feature is a general menu, which classifies the applications available in the system; using this menu, the user can find and launch the desired application task.

A big convenience provided by so many window managers for X11 is virtual screens . When a user is multitasking, he usually has to open many windows, so that they no longer fit without overlapping on the physical surface of the screen. To make it convenient to switch between tasks, you can use some specially designed functions of the window manager: minimizing and maximizing, moving windows “higher” and “lower” in the stack, a list of active tasks, etc. But it would be even more convenient not rearrange windows, and lay them out on a surface larger than the size of the screen - a virtual screen. Thus, the real screen is only a small “window” through which you can see only part of the virtual one, and if necessary, you can move this window to the other end of the “virtual table”, where windows with other tasks are located.

The window manager organizes the virtual screen itself: when the X server starts the window manager, it gives it one window the size of the entire screen, so that all other windows are inside it, and the window manager itself decides when and to whom to give the focus, how to deal with the windows and etc. At the same time, he may well “pretend” that his screen is larger than the monitor screen, following a certain command (switch to the other end of the virtual screen), remembering and hiding the current arrangement of windows and replacing it with another one previously stored in memory. The configuration of the virtual screen can be anything - it depends only on the logic of the window manager. A virtual screen can consist of several parts the size of a real screen, placed in a row, accessible by numbers, organized in the form of a rectangle, there are even three-dimensional virtual screens.

There are also virtual screens in WindowMaker; switching between them is done using a special button in the upper left corner of the screen or by using the key combination Alt + N, where N is the number of the virtual screen. However, in order not to forget where each window is, it is useful to be able to take a glance at everything laid out on the virtual screen. A window that displays a reduced-scale view of the virtual screen and allows you to jump to the desired part is called a pager and is a very common convenience in window managers.

Setting up the window manager

The convenience of a graphical interface is a very subjective concept, while it is technologically indifferent whether to draw buttons in the upper left corner or in the lower right corner, what color and font to use in the menu, etc. - all this makes up the profile of the window manager. Therefore, in the vast majority of window managers there are more or less developed capabilities to change the appearance and design of the graphical environment. In WindowMaker, a special utility with a graphical interface is used for this (Mephodius can call it using the topmost button in the upper left corner of the screen). In other window managers, such as the very advanced fvwm, the profile can simply be stored in a configuration file (~/.fvwm2rc), to change the appearance of fvwm you should edit this file.

Among the heavyweight window managers are fvwm2 (lots of features), Enlightenment (a real toy), WindowMaker, and some others. For a person who spends working time behind a computer screen, comfort in the workplace is important, so every little detail or lack thereof can be decisive when choosing a particular window manager.

Dimensions and weight

The motorcycle weighs 222kg with an empty tank, while a fully fueled X11 will weigh 254kg. The height of the car at the saddle reaches 795 mm, and the wheelbase is 1500 mm. The length of the motorcycle is 2145 mm, the width is 750 mm, and the height is 1115 mm. A tank volume of 22 liters is quite sufficient, taking into account actual fuel consumption from 7 liters to 9 liters per hundred km.

Honda X11


Brief review of Honda X11

Produced for just a few years, the Honda X11 naked bike is built on the basis of the famous Honda CBR1100XX Blackbird sports motorcycle, and has many common components with it. In fact, the Honda X11 is stripped of its plastic body kit and equipped with a derated Blackbird engine. Also noteworthy is the fact that, since this chassis was originally designed for a motorcycle with a plastic aerodynamic body kit, Japanese designers had to work on the aerodynamics of the Honda X11. Thus, the non-standard shape of the cooling radiator on this model is such because the radiator also serves as a rear wing, and the small dashboard protects from the wind.

Differing from the Blackbird with a retuned engine, the Honda X11 has better traction at low and medium speeds. However, the sporting roots of the motorcycle are felt in everything - in the landing, tenacious brakes and hurricane acceleration dynamics. True, this motorcycle did not gain much popularity, and was soon discontinued, but there are still clubs of Honda X11 admirers all over the world.

Pros and cons of the Honda X11

  • Mediocre wind protection
  • The timing chain tensioner requires regular inspection and periodic replacement.
  • Lack of sixth gear in the gearbox

Chassis and brakes

The space frame of this bike is made of aluminum, which makes it somewhat lighter. The X11's body is elegant, and every detail has been thought through to the utmost. Even the shape of the instrument panel is designed to improve the wind protection of the motorcycle. The wheel rims are, of course, alloy.

The rear suspension is pendulum, equipped with a monoshock absorber. At the front there is a 43 mm telescopic fork. The X11 brakes at the rear using a 256 mm disc together with a three-piston caliper, and at the front for these purposes a pair of 310 mm discs and three-piston calipers are used.

Driving impressions

The motorcycle is massive, it behaves confidently on the road, it doesn’t get blown away by the wind, it feels like a flying machine. There is a feeling of thoughtful wind protection. Relatively soft clutch, on a cable.

The motorcycle has reliable combined brakes, borrowed from the Honda Drozd.

They are designed in such a way that when you press any brake lever, the motorcycle brakes both wheels simultaneously. This motorcycle has clip-ons instead of a standard handlebar, which makes the riding position closer to that of a sports motorcycle. For aggressive and dynamic acceleration, this improvement is only a plus.

Estimated cost

Since Drozd was produced for only a few years , you are unlikely to find a new one.
But among used bikes there are many good options that cost around $400.

The estimated price may vary depending on the condition and mileage of the motorcycle from $300 to $600.

Simple and easy to drive, the Honda CBR 600 RR delivers performance in all conditions, be it the race track or narrow city streets.

This article reviews a motorcycle that is well suited for dense city traffic and maneuvering between cars in traffic jams.
