Step 1: RecordUse the recorder Recoder in the Camtasia Studio suite in the Screen modeEnable recording, mouse sound, mouse click prompt, and other options as needed. Generally, I only use recordings.The recording quality can be set to 22 khz and 16-Bit Single Channel. Higher quality is meaningless.Enable the microphone gain option. The microphone volume is about 70%, and the recording volume is about 70%.Do not increase the two in a loud fashion; otherwise, violence and

big procedure, you will be able to get out of bed in 4 or 5 days. The heart can not only change the valve, but also perform transplantation or even cardiopulmonary transplantation. In the afternoon, the doctor came over and said that he was going to split the cables and perform the examination. It seems that he can be discharged from the hospital, and I will leave for Guangzhou tomorrow. After lunch on the 6th, I arrived in Guangzhou with perseverance. Yesterday, my sister told my mother that t

them, the more famous is Morse decompositions, sweeping machine through it to achieve the division of space, followed by cleaning.In the 1970s, Carnegie Mellon University (CMU) relied entirely on ultrasound to do what we do now, and of course the cost is very expensive.Moving path planning from point A to point B described earlier is also the basis for such a more advanced path planning. In fact, there is still a lot of work to be done from slam to t

. The English alphabet is the preface:　　　　I. Introduction to the Linux daemon　　1. Alsasound:alsa sound card driver daemon. The ALSA sound card driver was originally written for a sound card gravis Ultrasound (GUS) and the program proved to be excellent, so the author started writing drivers for the general sound card. Alsa and Oss/free and Oss/linux are compatible, but have their own interfaces, even better than OSS.2. Acpid:acpid (Advanced Configurat

It is recommended that all notebook users open it. Some servers may not require ACPI. Common operations supported are: "Power switch", "Battery Monitor", "notebook Lid Switch", "Notebook display Brightness", "hibernate", "Hang Up", and so on.Anacron, ATD, CrondThere is a small difference between these

basically accomplish the same task; This makes it extremely difficult and time-consuming to provide support for external packages. Gentoo Maintainers decided not to continue supporting the Alsa-driver package, but rather to focus their resources on the ALSA drive portion of the Linux kernel.　　This guide will focus only on how to configure ALSA with the drive that comes with the kernel itself. Jaroslav Kysela used to be the leader of the project, which began as a driver developed for the 1998 Gr

A new word is being touched today, which is reflection, and I don't know what it is when I see the word reflex. So I asked the old man, the old man said to me can see a method is Gettipy () method, but what is this thing, through my search for information I am here to publish my own small understanding of it. One, what is reflection Of course, for the word reflection, we are not unfamiliar, such as mirrors can reflect, B-ultrasound is also the use of

the operation.Overlooking the entire car shop, it's equivalent to seeing a data flow graph Of course, TensorFlow also provides us with a lot of tools to help us get things done, such as motivating functions, normalization methods, gradient descent methods, which are helpful for machine learning. What TensorFlow can do? He can do some analytical work instead of us, we can enter some data, through a series of calculations to draw some conclusions.For medical workers, we can enter some images, su

1998 Gravis Ultrasound, which has been developed as a separate package until 2002 when he was introduced into the Linux kernel development version ( 2.5.4-2.5.5) 1. Starting with version 2.6, ALSA becomes the default standard audio driver set in the Linux kernel, and OSS is marked as obsolete. ALSA is a fully open source audio driver Assembly, in addition to providing a set of kernel driver modules like OSS, ALSA provides a library of functions speci

With the development of technology and the reduction of cost, the field of robot, unmanned aerial vehicle and unmanned driving has become an important application field of LiDAR in the field of laser radar. There are many kinds of sensors in the field of robotics, including cameras, lidar, millimeter-wave radar, ultrasound, infrared and many other sensors. The features and advantages of each sensor are not the same. The sensor sounds iffy, and many co

For object-oriented, more than n-Master wrote n multiple text. I dare not to fancy it. Simply talk about your own understanding. Let's take a look at "objects" and what are objects? Everything we can see in real life can be called objects. For example, enterprises, hospitals, pets, plants, people ... Wait a minute. In object-oriented programming, objects are often treated as a class with attributes and behaviors. We take the hospital for example, the hospital has the doctor, has the nurse and s

flight status information can be automatically updated. Like the communication networks of specialized computers such as ECUs in charge of automobile engines, the standards and technologies of the above two aviation industries are completely insecure and cannot resist potential active or passive attacks. Teso first detected and locked the flight to hijack with ADS-B, and then used ACARS to collect airborne computer information and by sending maliciou

The difference between abstract class and interface (interface)What is the difference between 10.Jre and JDKThe Java Runtime Environment (JRE) is the Java virtual machine that will execute the Java program. It also contains the browser plug-in needed to execute the applet. The Java Development Kit (JDK) is a complete Java software development package that includes the JRE, compilers, and other tools that enable developers to develop, compile, and execute Java program

(override) a private or static method in Java?The "static" keyword indicates that a member variable or a member method can be accessed without an instance variable of the class to which it belongs.The static method in Java cannot be overridden because method overrides are dynamically bound based on the runtime, while the static method is statically bound at compile time. The static method is not relevant to any instances of the class, so it is conceptually not applicable.4. Can I access non-sta

If your code tries to access a non-static variable without an instance, the compiler will give an error because the variables have not been created yet and are not associated with any instances.What are the data types supported by 5.Java?

I sometimes wonder what role I'm in. Product Manager? Or is it a project manager? Or just a technical manager.Some friends around said that they want to switch to become a product manager, to do a great product. I advise them to say or save it, in such a two or three-line city, airborne product Manager, will eventually become a handyman, do test, do business, tidy up the progress, collect and collect user feedback, how to do the product, the basic plu

West of the road, Wukong Huazai often in the ground before a circle, this is the heart to set the boundaries, but the human body (Tang's monk) will always be the Desire (pig) led away! so the person (master and pupil) is easy to leave the inner (goku) set of boundaries (strokes of the circle), so a boundary will encounter all kinds of demons (monsters). the Heart (Wukong) leads the person (master and pupil) unceasingl
