The following error occurs:GCC configure: Error: Building GCC requires GMP 4.2 +, mpfr 2.3.1 + and MCM 0.8.0 +From the error, we can see that GCC compilation requires GMP, mpfr, the three libraries, which I use for gmp-4.3.2, mpfr-2.4.2, and mpc-0.8.1. These three packages are downl

The Isosceles abc,ab=ac,m is given as the midpoint of BC. The P-point is the maximum point within the triangle that makes MIN{∠MPB+∠APC,∠MPC+∠APB}. Ask for P point trajectory.It is easy to find the P points on the centerline am satisfied so that ∠MPB=∠MPC,∠APC=∠APB, then ∠mpb+∠apc=∠mpc+∠apb=180°So the trajectory contains midline am.And all sati

function. UDP only transmits data packets regardless of the time sequence of data packets. RTP protocol data units are carried by UDP groups. When carrying RTP data packets, sometimes a frame of data is divided into several packets with the same time tag, you can know that the time tag is not necessary. The multiplexing of UDP allows the RTP protocol to meet the needs of multimedia sessions by supporting explicit multi-point delivery.Although the RTP protocol is a transport layer protocol, it i

This article understands All About Eve: Execute-verify replication for multi-core servers
Eve is a distributed replication solution designed to adapt to multi-core servers. State Machine Replication is designed to implement fault tolerance. Because it is difficult for all replicas to execute requests in the same order, Eve takes the measure to eliminate the limit that all replicas must execute requests in the same order, however, this does not mean that the request is not prepared for parallel

of frequencies, but because the Heterodyne spectrum Analyzer is in the frequency band scanning, therefore, unless the scan time to near zero, Cannot get the real time response of the input signal, so we want to get the same kind of heterodyne spectrum Analyzer as the performance of real-time analyzer, the scanning speed is very fast, if the scan time is smaller than the time constant of the intermediate frequency filter, the correct amplitude of the signal is not obtained. Therefore, to improve

Mixer wants to provide custom routing, SQL blacklist to prevent SQL injection attacks in the proxy layer, and the cornerstone is to parse the SQL statements sent by the user. That's my first big lexical analysis and grammar analysis.
So far, I've just implemented a simpler lexical analyzer to decompose SQL statements into multiple token. And for the syntax analysis from the token, build the SQL AST, I now really have no experience (compil
