Microsoft discloses details about Windows Subsystem for LinuxLast month, Microsoft officially announced that Bash on Ubuntu on Windows has supported Linux ELF64 binary files in Windows 10 using Windows Subsystem for Linux (WSL) native. WSL was developed by Microsoft's Windows Kernel team. Since it was announced last month and provided for trial in Windows Insider Build, many users are interested in learning how Windows Kernel Team establishes this subsystem.

1. Use 2400m ~ 2483.5m band
2. Data is transmitted in FM mode, with a total of 79/EDR and 40/ble hops per second.
3. gfsk (dqpsk and 8 DPSK) modulation
4. channel interval (1 MHz/EDR mode, 2 MHz/ble Mode)

The Bluetooth system provides point-to-point or point-to-point connections. In the connection, devices share physical channels, which are called piconet. One device acts as the master, and other devices act as
Jon Tirsen said in his weblog that he had seen an interesting project called Picocontainer and was immediately engaged.

The value of path is a series of directories that Linux searches for when you run a program. You can see the value of path with the following command.
$ echo $PATH
For example, in a host, the user Yogin path value is:
/opt/kde/bin:/usr/local/bin:/bin:/usr/bin:/usr/x11r6/bin:/home/yogin/bin
where ":" is the separator. So, a list of directories above can be considered as the directory listing below.
/opt/kde/bin /usr/local/bin /bin:/usr/bin /usr/X11R6/bin /home/yogin/bin

Introduction
Bluetooth technology is a wireless data and voice communication of the open global norms, is used to replace mobile devices or fixed electronic devices to connect cables between the proximity of the Wireless Link, Bluetooth work in the global 2.4GHz Band, data rate of 1mb/s, using the time Division duplex transmission technology to achieve full duplex transmission.
As a short distance wireless communication technology that replaces the data cable, Bluetooth supports point-to-point

Since the ATX power supply has been on the "Rivers and Lakes" for several years, as long as the CPU is not an Intel MMX or AMD K6 or lower computer, I believe it should all be an ATX power supply.2.

My friend recently asked me this question: one of his two computers is using ADSL to access the Internet, and another notebook is working on mobile phones. He wants to enable remote access to his home computer and perform operations on his laptop. After three days and three nights of close-eye efforts, I finally helped my friends realize this dream! The implementation scheme is provided for reference. Here, we call a friend's home computer the controlled computer, and his notebook the master com

Since I have not participated in social practice in Hollywood, it is difficult to understand this sentence.IOC is a new design model, namely the IOC mode.
