processors, the L1 cache can concurrently process two accesses, and access to the same storage body can only be serially processed if the access is from a different storage body. And the processor Smart optimization strategy also surprises you, such as in the case of pseudo sharing, previously on some not tuned machine performance is not good, but my home machine can optimize the simplest example to reduce cache flushing.
Here's a strange example of a "Hardware Freak":

What is Micro Service
First, micro-service is not a name, but an architectural concept, just as restful not only describes the format of the API, but more describes the architecture based on the RESTful API. A micro-service architecture (MSA) is a large system that is dispersed into many small systems through horizontal or vertical, business, or architectural segmentation, for the original large systems. When the system is complex to a certain extent
Challenge", an unmanned car race held in 2007, used heuristic search to plan flat, direct, and accessible routes. Heuristic search has also been applied successfully in natural language processing, which is used in the parsing of text and stack decoding in speech recognition. It is also used in the field of robotics and bioinformatics. Compared with traditional dynamic programming methods, using heuristic search can solve multiple sequence alignment (multiple Sequence alignment,

As a result, many operations on internal lobs can participate in transactions, You can also back up and restore operations as you would with normal data. Oracle supports three ty

described earlier. If the load is charged less than the maximum SOA time, the MOSFET is appropriate. In this example, the MOSFET conforms to the standard (0.9 msA timer value less than 2 MS is sufficient to protect the MOSFET, and larger than 0.9 MS is sufficient to charge the load. If the selected time is constant at 1 ms, then the capacitance can be calculated by the following formula:where ITIMER = 60μa and vtimer = 1.3 V,When using a parallel MOS
