The scientific community is in urgent need of leading figures. But what is a leader? What are the characteristics of a good leader? What is the difference between scientific leaders and other leaders? There is a misleading situation where the title is equivalent to the title of a leader. I would like to try to think about these issues as a scientist and a management practitioner.

of other PCs on the same HUB is normal. The FLUKE DSP4000 cable tester was used to test and found that the link distance from the PC to the HUB was 361 feet m), and the attenuation failure was reported along with the long cable instrument. Cause analysis: the signal attenuation is too high due to the excessive cable length, which leads to the failure of the signal receiver to correctly identify the signal.

Because PHP is an open language, it also leads to a lack of strong and authoritative support for the development environment. Here are some of the better editing tools, I hope to give you to develop PHP programs to provide some help.

Starting with MX, DW has started to support Php+mysql's visual development, which is a good choice for beginners, because if you are a general developer, you can write a program almost without writing a single
declaration. If the preceding variable name is written incorrectly, the system allocates memory units for two different variables, which leads to incorrect calculation results. Therefore, to prevent such errors, you must restrict them to Explicit declarations, that is, add the Option Explicit statement in the General Declaration section.

information leakage. At the design level, the API actually defines your system architecture.
The more detailed the module decomposition, the smaller the module, the more important the API definition. The overall complexity and likelihood of errors also decrease.
However, if too much decomposition leads to too small modules, unexpected situations may occur. The figure below is from the statistical data of Hatton in 1997. The image is U-shaped.

, Exception Handling, Logging, Validation, and even Performance Counter. I am used to turning these non-business logicInfrastructure Logic. Because these Infrastructure logics are usually injected into the execution of specific business Logic based on specific needs, they are moreCrosscutting Concern.
According to the traditional OO programming method, we usually combine these Business Concern and Crosscutting Concern, which leads to a tight coupling

They only need to intentionally allocate some content they have never done before when receiving the task, at the same time, after arranging an experienced person to work with him, the people in the team will gradually realize that they just focused on a different way of working in a module. 2.3 How to Reduce the inventory of semi-finished products and shorten the delivery cycle
The lead time [4] of a requirement is the time it takes from being identified to being finally delivered to the use
programmers through their "Pride", which leads to a vicious circle. People always say that "intelligence is the opposite of being intelligent." In the programmer's world, there are countless roots planted for such "little smart. So far, we are still struggling to make up for the mistakes made by our predecessors.
So from today on, I plan to record my thoughts on these "smart" ideas. I hope that people who have read these ideas can discover the subt
large and small quarons In the hadrons will naturally re-generate mutual effects and combine them in one piece. This, it is a phenomenon of strong interaction.
After all, the essence of strong interaction lies in the fact that the central body of an unsaturated game's empty child refit permeate the central polarity through the insaturated comprehensive circulation body and is similar to other unsaturated game's empty child weights. the external layer of the fit generates mutual attraction, in

In other words, you delay the operation ction moduloSIZE. For this to be efficient, you normally want to pick a power of 2SIZE; This makes the wrapping computation cheap and will automatically do the right thing if one of the positions ever overflows. This leads to very straightforward, efficient cod

Originally, the two old people entered the famous Hilbert Hotel in mathematics, which is considered to be a hotel with numerous rooms.
The story of Literature goes on like this: the kind of waiter leads the old man to a room and says, "maybe it is not the best, but now I can only

Unit 3 exploded again around on January 1, March 15. Unit 4 caught fire, causing a large amount of radiation leakage. So far, Japan has been actively handling the nuclear accident.
We can say this is a natural disaster. However, I think this is a "man-made fault". There are many design and implementation defects in the middle, which
functional points or the preconditions. This fatal defect directly leads to the constant discovery of omissions in the development process, so that we have to improve the missing items first. The final development volume roughly estimates that there are 1.5 times of requirements documents above. In fact, many people have such experiences, and even feel that this is a good news. Many project development projects do not need to change. But this is not

The waste rate and safety stock based on this setting are too high, which leads to an increase in the quantity of raw materials purchased and the production quantity of self-made parts, this leads to an increase in inventory.

While hardly surprising to any git user, this feature is readily appreciated by everyone. Also, for minor changes BitBucket actually allows editing from within the browser.
