through 「 Today in history 」, Look at the future from the past , You can change the future from now on .

It's today 2022 year 6 month 7 Japan , stay 1742 Years of today , Prussian mathematician Christian · Goldbach is writing to Leonhard, a Swiss mathematician · Euler's communication , Put forward the following conjecture ： Any greater than 2 Can be written as the sum of three prime numbers . This is one of the longest unsolved problems in number theory , Goldbach conjectures . Goldbach conjecture made no progress for a long time after it was put forward , Until the 1920s , Mathematicians have proposed solutions from two aspects of combinatorial mathematics and analytic number theory , And made a series of breakthroughs in the following half century . At present, the best result is that Chinese mathematician chenjingrun 1973 Chen's theorem published in （ Also known as “1+2”）.

Davis used after consulting linguists “ Data packets ” The word , Because it can be translated into other languages other than English without ambiguity .

Davis later worked with his deputy Derek Barber and Roger Scantlebury The network interconnection protocol is studied together . They come from 1972 Started to participate in the international network working group , And in 1973 In published “ Computer communication network ”. For a long time , The network engineering community is polarized in the implementation of the competitive protocol suite , This argument is often referred to as “ Agreement war ”.1979 year , Davis got out of the vortex of the Internet Protocol war , Turn to computer network security ;1983 year , He and David O. Clayden Designed the message verifier algorithm together （MAA）, This is one of the earliest widely accepted message verification code algorithms .2000 year 5 month 28 Japan , Davis died , At the age of 75 year .

K8s Originally by Joe · Beida 、 brandon · Burns and Craig · McCluskey founded , Brian · Grant and other Google engineers soon joined .K8s The development and design of Google Borg System impact , Many of the top contributors to the project have previously worked in Borg Work in the system . Nowadays, the common abbreviations in the information field “K8s” Will be “ubernete” The eight letter abbreviation is “8” And come .Kubernetes The core value of the project , It is a series of 、 In the form of voice API The idea and best practice of container job scheduling driven by . On this basis ,Kubernetes It provides users with a set of basic dependencies for building distributed systems based on containerization .
