. This method is slightly different because it does not have to register all the services, after all, we only care about a part of the service. Code git checkout P7 Scaling and load Balancing Let's see if we can start more than one Accountservice instance to implement the extension while watching us swarm automatically do load balancing requests.In order to know which instance replies to our request, we add a new account structure and we can export the IP address.

Gorilla also supports complex routing using regular pattern matching, schemes, methods, queries, headers values, and so on. Therefore, path and path parameters are not limited. In respo

context to the error. Instead I recommend using something like to pkg/errors capture a stack trace at the point the error occurs. Registration A registration pattern is followed by several packages in the class library such as net/http , database/sql , flag , and to a Lesse R extent log . It commonly involves a package scoped private map or struct which are mutated by a public function-a textbook singleton. Not being able to create a package scoped placeholder for this state would remove the si

Address:Http://localhost:8080/core.cssThe same get is index.html the content of this page,Which means that our registered route also matches the/CORE.CSS request. What is the problem?We have to write a route function ourselves to see how it matches the route:Let's take a look at the documentation for go: Look at the declaration of the Listenandserve function: stringerror If you want to write the route function, you have t

After the server opens a request comes in, the first call is Server.servehttp (rw responsewriter, req *request). func (mux *ServeMux) ServeHTTP(w ResponseWriter, r *Request) { ..... h, _ := mux.Handler(r) h.ServeHTTP(w, r)} The above function goes through Daoteng and fina

scenario, each request to start a goroutine to serve it, so that the parallel effect. This kind of goroutine directly according to the logic of thinking to use Goroutine Performance optimization requires concurrency One scenario is this: a message needs to be sent to a group of users, and normal logic uses for _, user := range users { sendMessage(user)}//但是在考虑到性能问题的时候，我们就不会这样做，如果users的个数很大，比如有1000万个用户？我们就没必要将1000万个用户放在一个routine中运行处理，考虑将1000万用户分成1000份， //每份开一个goroutine，一个goroutin

the standard DIMM has enough space to accommodate the 9th chip, and the 9th chip is used to store 4bits or 8bits of ECC.If the 9 chips of the 1 ECC DIMMs are on the same side of the DIMM, they are called single-sided, and if 9 chips are distributed on both sides of the DIMM, they are called double-sided.DIMMs are also divided into Single-rank, Double-rank, Quad-rank (that is, 1R, 2R, and 4r,4r DIMMs that we often see on the lable of memory are typically used on the server).Each rank of Double-r

AbstractIn OpenGL, always block can be used to represent flip-flop, combination logic and latch. In this article, always block represents the power path without modifying else. IntroductionIn the C example, else is omitted, but it does not mean it is handled. However, else does not represent a different electrical path in the Tilde. Always@ (OrBOrEn)If(EN)C = A B; Else is omitted in combination logic ~ En retains the original value, so latch is generated. Always@ (Posedge CLK)If(EN)C It

based on the internal and or Array Logic, these devices are mostly made using the eeprom or flash process. configuration data is not lost after power loss, and the device size is generally less than 5000. 2. PLD Device Based on the structure of the query table (LUT: look-up table) The scale of the and or array-based PLD Device is not easy to be very large, so the designer developed another programmable logic device, that is, to find the table structure. It is similar to Rom. Its physical struct

Basic Concepts literacy, Container (Container), Stream (Stream), Frame (Frame), Codec (Codec), mux/demux (multiplexing/demultiplexing ).A: A container is a file, and a container is a file format. For example, xxx. flv and yyy.mkv are two files. We can say th

The network data interception at the TDI layer can also obtain detailed information about processes that operate on network data packets, which is also an important feature of the personal firewall.NDIS middle layer driver. The middle layer driver is between the protocol layer driver and the small port driver. It can intercept all network packets

formatThe multimedia container format is like the multi-media format we use. MP4 ,. 3GP ,. avi ,. ASF and so on are all multimedia container formats. They contain multiple encoding formats of video and audio. In multimedia, MUX and Demux are used to mix audio and video data (MUX) in the file format) and Demux In the decoding process ). Let's take a look at several container formats: 1. MP4A multimedia cont
