this reason, the lens has a pin used to shrink the aperture, and the lens name has become auto takumar. Xuguang also launched the brightest SLR lens auto takumar 55mm f/1.8 As a pullover. The camera is black and white and has characteristics. The unit price is 51,500 yen. Bind K only produces 21,500 units in a year.
Starting from May 1959, bind began to manufacture bind S2 in bulk, with amazing output.

Fgrep □find a fixed string. "F" doesn't mean "fast"-in fact, "fgrep foobar *. c" is generally slower than "egrep foobar *. c" (a little surprised, don't believe itYou can try it yourself ).Even so, Fgrep still has merits. When searching strings in an archive, Fgrep can process more strings than egrep.
Egrep = "Extended GREP"
Egrep uses a regular rexpression that is more fancy than grep. Many people always only use egrep because algorithm is more advanced than grep or fgrep, whileIt is usuall
-time database structure design mainly designs the real-time database structure according to the characteristics and requirements of the SCADA system. The management program is responsible for the generation of real-time databases. Based on the on-site modification content, it processes real-time requests from other tasks to the real-time databases and responds to the external environment through alarms and remote control.
[Real-time database comparison]
Relational databases are widely used and
is characterized by rapid response, good linearity, and long-term stability. After some peripheral circuits are added, the capacitance changes can be easily measured. This is a common form of humidity measurement by capacitive sensors.With the development of sensor technology and the increasing requirements of users, sensor manufacturers have already integrated signal conditioning circuits on multiple sensors, the sensor itself can output convertible or slightly sorted signals for conversion, w

We have introduced the features and structure of ROS. Next we will begin to prepare for the strong ROS. On the wiki on the ROS official website, the tutorials for new users are very detailed. It is best to clarify all the tutorials for new users. This is the most basic thing for later development. Despite this, ROS is still difficult for beginners to get started. Here, I will summarize my learning history and serve as a reference for other new users.I
