Through "today in history", we can see the future from the past, and we can also change the future from the present.
Today is August 27, 2022. The two giants of Internet companies , Microsoft and IBM , coincidentally released their latest technological achievements on the same day 21 years ago; Microsoft released the latest IE browser series on this day. The classic work Internet Explorer 6.0, and IBM announced on this day that it has built the world's smallest logic circuit.
August 27, 1926: Kristen Nygaard, developer of the SIMULA language, is born
Kristen Nygaard was born on this day in 1926 in Oslo, Norway, and is a well-known computer scientist and social activist. After graduating from university in 1948, he joined the Norwegian Defence Research Institute NDRE, where he worked in computing, programming and operations research. Through continuous efforts, he became the founder of the SIMULA language, the pioneer of object-oriented technology, and won the von Neumann Award (2001) and the 36th Turing Award .
SIMULA-I and SIMULA-67 were developed in 1967 by Christian Nygart and Ollie-John Dahl of the Norwegian Computing Center. SIMULA is considered to be the earliest programming language for Object-Oriented Programming (OOP, Object-Oriented Programming) in the world. SIMULA introduced for the first time the basic concepts of object-oriented programming languages: objects, classes, inheritance, virtual quantities, multithreaded (quasi-parallel) program execution. SIMULA not only introduced the concept of "classes" but also applied the idea of instances - probably the earliest application of these concepts.
The late 1960s was an important period in the history of computing. Three important languages came out during this period, namely SIMULA 67, Algol 68 co-designed by a group of top computer scientists, and PL/I developed for IBM 360 series machines. Although all three languages have innovations, the influence of SIMULA 67's object-oriented concepts is the greatest and far-reaching. By the 1970s, structured programming language and structured analysis and design could no longer meet the gradually expanding application fields, so object-oriented technology (OOP) came into being, and SIMULA language was the ancestor of OOP.
With the development of time, in order to solve those places that OOP can't take care of, Aspect Oriented Programming - AOP (Aspect Oriented Programming) was born. OOP and AOP are different in terms of goal orientation, ideological structure and emphasis, and there is a complementary and perfect relationship between the two. Christen invented SIMULA in order to solve the defects of structured programming, and later generations learned from his ideas and invented the concept of AOP. These great creations are essentially derived from the needs of users.

August 27, 2001: Microsoft releases Internet Explorer 6.0
On August 27, 2001, Microsoft officially released version 6.0 of the Internet Explorer browser (IE), a few weeks before the official release date of Windows XP. This release includes enhanced DHTML, content restrictions for iframes, and partial support for CSS level 1, DOM level 1, and SMIL 2.0. The MSXML engine will be updated to version 3.0. Other new features include a new version of IEAK, integrated media bar and Windows Messenger, error collection, automatic image resizing, P3P, and a new look that works with Windows XP's "Luna" interface.
Many netizens now have experienced the period of IE 6.0 - 8.0. IE6 is a widely popular version. Who doesn't know the "IE bundled with Windows XP"? The multi-tab browsing function that we often use now appeared in the subsequent 7.0 version; however, IE 7.0 and 6.0 have the same problems, and many websites cannot be opened perfectly due to compatibility problems, so many people at that time had to switch back to IE6 to use .
In addition, the period of IE 6.0 - 7.0 coincided with the emergence of Mozilla Firefox , which instantly robbed Microsoft of a considerable part of the browser market by virtue of its advantages in security and open source expansion, breeding many stories...
Between IE6 and IE7, Microsoft did not update its own browser and operating system for 5 years, resulting in a very serious problem with IE's standard support; this also allowed Firefox to take advantage of the situation and launch the second browser war. The problem of poor standards support is a headache for web engineers, because although it is at least five years out of date, it still has a market share of about 17%, so that people who write web pages have to take this group of people into account.
When it comes to IE6, we have to talk about Windows XP, which "doesn't live with it, but die with it". It can be said that the popularity of Windows 7 directly declared the death sentence for IE6 and Windows XP. On January 5, 2012, the Microsoft IE team specially customized a "GOODBYE IE6! (say goodbye to IE6)" cake to celebrate the glorious retirement of IE6 . Roger Capriotti, director of Microsoft's IE marketing division, said on the Windows team blog: "IE6 has been a joke among peers for a while, so we're more desperate than anyone to want it to go away. In fact, we're in The IE6 countdown site that launched last March helped drive this process a lot."
IE6, born in 2001, finally "killed love" with Windows XP on April 8, 2014, but these two old guys will always be remembered by the Internet. Both IE6 and Windows XP have affected many netizens around the world, and they are an inescapable page in the history of the Internet.

August 27, 2001: IBM announces successful development of the world's smallest computer logic circuit
The number of circuits integrated on an integrated circuit chip doubles every 18 months.
(The number of transistors on a microprocessor chip will double every two years or so.)
Fifty-seven years ago today, Gordon Moore, one of the founders of Intel, conveyed a prediction to the computer world - Moore's Law, which has been affecting the technology world for 50 years. In 1946, the silicon transistor came out and was used in computers to help mankind for half a century. As predicted by Moore's Law, the manufacturing process level of semiconductor chips doubles every 18 months.
However, silicon transistors always have their own limits, so people have been tirelessly looking for Millivolt switches to replace silicon in an attempt to break Moore's Law.
A carbon nanotube, a hollow tube body 100,000 times thinner than a human hair. Because of its extraordinary energy and semiconductor capabilities, IBM researchers believe that it is most likely to replace silicon in the future, open up a vast space for future chip manufacturing, and improve the performance of existing chips by thousands of times. The new development of computers is in This novel tubular structure was developed.
On August 27, 2001, IBM announced that they had successfully developed the world's smallest computer logic circuit, which is a two-transistor element composed of carbon molecules, among which the carbon molecules are carbon nanotubes. This material can not only be small in size, but also has the characteristics of super conductivity and fast switching speed. Replacing silicon with this material for transistors will enable future computer chips to be smaller, faster and consume less power.
In 2013, IBM used carbon nanotubes to make electronic circuits, and also developed a "hybrid" integrated circuit, using carbon nanotube materials where high precision is required, and continuing to use silicon materials in general places to extend the use of silicon materials. life.
To this day, human research on carbon nanotubes is still continuing, and the GAA that Samsung is promoting and the negative capacitance transistor being promoted by Professor Hu Zhengming, the inventor of FinFET, are also strong competitors for carbon nanotubes. In 2020, Tsinghua University made a major discovery in the direction of carbon nanotubes . Today is the node of the "post-Moore era". No one knows whether Moore's Law can be continued with breakthroughs in chip technology. This is also the biggest charm of the unknown, attracting generations of researchers to work hard for it.
Taking history as a mirror, we can know the rise and fall. Since the development of computer science, there are many important events and figures.
