alley. The deep reason is that we want to learn something and unconsciously continue a kind of thinking that is not very reasonable. The learning model has been simplified. While criticizing the disadvantages of systematic teaching in this major, on the one hand, we have to pursue this kind of systemization in an originally unrestricted and free arrangement.
Systematic learning means that a relatively large and long-term plan will begin. Start up with ambition, or stop without knowing it. I hav
:
At the early technical level, we need to develop various data processing algorithms and subsystems in advance to implement a data processing system, which is solidified in the program, this design is like when we design a analog circuit, we need to first draw the circuit board, and then weld each component, and then debug and process it... Different applications have different circuit boards, so the flexibility is poor!
If our data processing meth
OpenShift began to support CentOSGuideTwo weeks ago, after CentOS announced its participation in RedHat, OpenShift, A PaaS product of RedHat, officially announced its support for CentOS.
OpenShift indicates that running OpenShift on CentOS is slightly different:
First, we provide some new packages for the avahi-based MDNS multicast support. Secondly, we ensure that all the packages compiled under EL6 are not dependent on CentOS. In addition, we perform a complete test.OpenShift is a platform-a

3. What is the difference between pigtails and jumpers? Can jumper be split into two parts as pigtails?
In fact, both the optical jumper and pigtails are optical fibers! The protective layer of the optical fiber jumper is thicker, which is connected to pigtails and terminal devices.Pigtails are used in the trunk box to connect the optical fiber cables and the flange of the trunk box.
Pigtails are used

Another test is the assembly of optical inspection and on-line testing, optical inspection of the design has no clear constraints, as long as the circuit has a certain degree of visibility can be detected, the method is mainly to check the quality of installation and welding.

Initiated: December 27th, 2012 Preface
The single-chip microcomputer, once fascinated for a while in the university era, was dropped after graduation. After many years, the interest in electronic production began to rise again, so the MCU was replayed.
It is enough to make use of hundreds of RVs, tiny13, 2313, and ipv8. But with a single-chip microcomputer, there is no way to use it without a down
Today, a strange problem occurs:1. Add a flying line to FPGA on the OE pin of nor flash. As a result, the flying line is lost and the system cannot be started when the welding is re-performed. When we re-weld, the network encountered a problem.
And cannot be operated. Failed to find the kernel image file after a TFTP system fails to be written.2. Considering that the nor flash may be burned out during welding, a new nor flash was replaced. As a resul

I thought that the motherboard seemed to have a com-lead accessory. So I found the motherboard specification, and the motherboard had a comport. I thought that since the USB comport is not good, maybe the motherboard can come with it, so I found a com lead in the accessories and opened the chassis to bring the comport to the rear panel of the chassis.
Connect to the com line, open putty, Boot, LINUX started, com still did not respond. At this time, a technical support on QQ reminded me that th

Sorry, I spent a night yesterday and used a knife to engrave an operating system on my hard drive. I want to learn from you!3. Blow it up, brag about tax-free ...... I split the old TV in my house yesterday and turned it into a gf4ti4800 video card ......4. What is this? Just now I went online while eating an apple and suddenly crashed. After
only know how to learn DSP, how to draw PCB, and how to print circuit boards, I learned how to weld components. I was so busy all day, and I was often excited to make a real doorbell, power, and other things, but they seemed to look down on physics and look down on these basic disciplines, look down on these abstract knowledge, and look down on these human souls. Sorrow: the greatest sorrow is to laugh at the real profound things with your ignorance
. Note the scale of the grid. It's best to do the import test of each modeling software model to set the correct scaling ratio (different modeling software import scale is not the same)3. Placing the character allows the foot of the character to stand at the origin of the coordinates or the "anchor point" of the model. A character usually walks vertically on the ground, and if the character's anchor point (that is, his transformation center) is easier to control on the ground.4. If you are a hum

Attention: Do not wash with water! The heatsink can be washed and the card will not be washed. Although in theory can be washed, but the difficulty is ordinary users how to dry it ... The droplets in the gap between the components and weld feet are very difficult to manage, and can cause some metal contacts to rust. So it's more safe to use brushes and fur tigers to deal with the dust on these compo
