Java deserialization, object injection can cause code execution vulnerability
0x01 PrincipleJava deserialization results in the same principle as PHP deserialization, because user input can control the input objects. If the server program does not verify the user-controllable serialization code but is used for deserialization, and the program runs some dangerous logic (such as eval and login verification ), this will trigger unexpected vulnerabilities. In fact, this is not a new issue. For detai
In electronic circuits, power supply, amplification, oscillation, and Modulation circuits are called Analog Electronic Circuits because they process and process continuously changing analog signals.
1. Feedback
Feedback refers to sending output changes to the input end in some way as part of the input. If the return part and the original input part are subtracted, It is negative feedback.
2. Coupling
An amplifier usually has several levels, and the association between levels is called coupling.
isolated exchange Buck circuit: 3.3 V, 5 V, 12 V,-12 V, and 5 V standby (5vsb) for standby when the computer is shut down ). Therefore, the power supply also has high-voltage and high-power components, as well as small-power components that process low voltage and control signals.
The power conversion process is AC input → EMI filtering circuit → rectification circuit → Power Factor Correction Circuit (active or passive PFC) → power level primary side (High Voltage Side) switching circuit to p
technology, there are many accessibility features, such as the editing management tools available to developers in ESB Studio, as well as a separate service registration snap-in, and monitoring subsystem functions such as the ESB middleware monitoring platform.
It seems that the Meta ESB Middleware has a community version that can be downloaded and used by developers. But the functional aspect certainly is not as comprehensive as the paid version.

difference, resulting in thermal stress and thermal shock. The component is subjected to thermal-mechanical stress. When the temperature difference is too large, different parts of the component may produce stress cracks. Early component failure. This requires that the power element should work in a relatively stable operating temperature range to reduce the sharp changes in the temperature, so as to eliminate the impact of thermal stress and ensure long-term reliable operation of the element.
