"A set of large-scale air-conditioning equipment and sprinkler irrigation equipment, the investment is not smaller than that of a planting greenhouse, your courage is not small!" Li Xuan smiled at Chen Tao, who was beside him.

It was under Li Xuan's instructions that the Oriental Research Institute installed a computerized control system for Chen Tao in one step, instead of the rudimentary temperature alarm device he had originally planned.

The real power of AIPC-100 calculations is when the computer receives the number of jù sent back by the temperature sensor and finds that the temperature in the greenhouse exceeds 25 degrees Celsius. The computer program will automatically turn on the air conditioning equipment to cool the greenhouse. Similarly, the computer will automatically sprinkle the roses in the entire greenhouse at a fixed time every day according to the program set by the administrator in advance.

This was an ordinary technology on the street 30 years later, but in 1982, it was already a great high-tech. In order to achieve this ability, it is natural that Chen Tao, the owner of the greenhouse, needs to invest in the purchase of corresponding air conditioning and sprinkler irrigation equipment.

"My wife and I used to travel to Malaysia and found the rose garden there to be very beautiful. Hong Kong consumes a lot of roses every year, but it does not have its own flower planting industry, so it needs to import a large number of roses every year. I think it's an opportunity and I'm ready to give it a try!"

Chen Tao began to talk about his entrepreneurial history, "I have collected information and found that the summer in Hong Kong is too hot, which is not conducive to the growth of roses, and it is easier to control the quality of flowers only by adopting greenhouse farming!

Originally, my father did not approve of me continuing to expand my investment, but my grandfather agreed. He said Li Sheng, since you are willing to provide advanced technical support, there is no reason not to give it a try!"

The Oriental Research Institute accepted Chen Tao's automation transformation project of the planting greenhouse. Naturally, it is for Chen Xinli's face. Otherwise, how could the Oriental Research Institute be interested in taking on such a small project. In order to realize temperature control and sprinkler irrigation automation, Dongfang Software has also developed a special application applet.

If the Chen family is unwilling to invest, Li Xuan doesn't need to spend all these twists and turns, just find someone to get him a temperature alarm. But Chen Xinli's courage was still enough, and Chen Taotong guò guò guò he got the loan funds from the bank. Not only is it enough to purchase air conditioning and sprinkler irrigation equipment, but also the construction of the second phase of greenhouses will be carried out.

In this case, Li Xuan is also willing to spend some energy to make this project a model project, as a business card for the future promotion of AIPC-100 industrial control computers in Hong Kong. AIPC-100 is a general-purpose industrial computer, which is suitable for the automated production needs of many factories. The scope of application is by no means limited to such a small temperature-controlled greenhouse.

"I may need a larger quantity of roses for my wedding in May, and if you can supply them here, I don't need to import them from abroad!" Li Xuan said, which was the main purpose of his visit today.

"Li Sheng, how much do you need? If it doesn't exceed 100,000 flowers, I can eat it here!" Chen Tao agreed without a big package. Instead, he asked cautiously.

"100,000 flowers should be enough, tomorrow I will call someone to come and contact you, whether it is enough or not, I will give priority to purchasing from you!" Li Xuan said with a smile, "Hong Kong's flower market is not small, if you do well, you can also grow other higher value-added flowers in the future." Like phalaenopsis and the like, the Chinese New Year's Eve flower market in Victoria Park is popular every year!"

"Brother, in addition to red roses, there are also white roses and yellow roses here!" Li Ying held a bouquet of roses. He walked over and said in a slightly surprised tone.

She picked out all the red roses in her hand and handed them to Li Xuan, leaving only the white roses left: "These are for you to please your second sister-in-law!"

Li Xuan chuckled and took the rose. The flower language of red roses is passion and true love, and the flower language of white roses is pure and innocent.

It was two people when they came. When they went back, there were three of them, and Zheng Chengyi and Li Xuan also returned to the Shiyàn Building of the Sha Tin Oriental Research Institute together. Today can be said to be the first practical application and debugging of AIPC-100 computer, and Zheng Chengyi specially came to the scene to have a look.

"After the AIPC-100 is launched, the follow-up development of various functional modules must also follow immediately!" Li Xuan said.

The AIPC-100 industrial computer has up to 6 external card slots, which can be configured with different external components to achieve various functions. For example, the installation of a data collection card can strengthen the computer's data collection and analysis capabilities. Let the AIPC-100 computer have a wider application in industrial testing, real room analysis and other fields.

Zheng Chengyi nodded, he is the general person in charge of the industrial control project. Oriental Research Institute, in addition to the already completed AIPC-100 computer. At the same time, it is also developing industrial control single-board computers and other products, preparing to form a rich and complete product library for users to choose.

"The East-Unix operating system developed by Dongfang Software Company is still easy to use!" Li Xuan asked.

The AIPC-100 industrial computer does not use the East-DOS operating system like the previous ABC series computers. Instead, it uses the new East-Unix operating system. Dongfang Electronics had already obtained the UNIX development license from the Bell Yàn room in 1980 to develop its own UNIX version of the operating system.

For ordinary people, the only computer operating system they usually come into contact with is the Windows series of Microsoft's Great Demon King. In the enterprise market, Windows Server has not been able to dominate the world as much as it has in the PC space, and its main competitor is UNIX.

The UNIX operating system was developed in the late sixties by two researchers in the Bell Yàn room, and gradually spread after being rewritten in C in 1973. At that time, the Bell Solid Room didn't take the operating system too seriously.

As a result, the source code of UNIX spread rapidly, and in 1979, when the Bell Sil Yàn Room began to realize its commercial value, it was impossible to gather it together for fine commercial development because the source code had long been scattered.

Therefore, the Bell Shi yàn room simply broke the jar and broke it, and adopted the model of external authorization, with the use of research institutions free of charge, and the use of enterprises to pay licensing fees. Li Xuan obtained the development authorization of the UNIX system from the Bell Shi Yàn room early.

His idea was clear from the start. The personal-grade operating system uses East-DOS to achieve as easy to use and feature-rich as possible. Enterprise-level products that require higher stability and security use the more concise and stable UNIX system.

From its birth to the gradual commercial application of Unix, it has been "raised in the depths of the people" for almost 10 years. It was during this long period of time that the Bell Room and other scientific research institutions and universities continued to make argumentative revisions to the UNIX system.

All UNIXs are in commercial development. The system has been very perfect, which is the fundamental reason why UNIX has been firmly in control of the enterprise market with high requirements for stability and security for a long time. Naturally, it is impossible for other commercial software to spend such a long time looking for bugs, and it is inevitable that a lot of holes and patches will be left in the software.

For example, the later Microsoft Windows system has been sprayed since its birth, and there are as many loopholes as a sieve. It's not that Microsoft's developers are too technical. It's the entire Windows system, with tens of millions of lines of code. Finding bugs is a huge undertaking, and Microsoft can't afford to spend years fixing them.

The East-DOS system previously developed by Dongfang Software Company also has a million lines of code, and Li Xuan is also unlikely to spend too much time looking for system vulnerabilities. Instead, it will choose to solve the problem by adding a patch when the vulnerability is discovered.

"This east-unix set is pretty good, but the interface adoption seems to be biased towards ucb-unix?" asked Zheng Chengyi.

Li Xuan nodded and said, "East-Unix of Dongfang Software is developed by the American R&D center, and most of the members of the development team are masters recruited by the company from the University of Berkeley (UCB)!"

Berkeley's version of the Unix system is the most influential version of the room outside of the Belsil Yàn room. For this reason, the Bell Syàn room also sued the University of Berkeley on the pretext of infringement, trying to block this version through legal means.

"We at Berkeley are indeed Crouching Tiger, Hidden Dragon!" Zheng Chengyi said proudly.

Only then did Li Xuan remember that the person in front of him was an alumnus of the University of Berkeley. When it comes to his alma mater, he is naturally full of pride.

The shortage of software development talents in Hong Kong is a very real dilemma, and it is not easy to gather a R&D team to develop the East-Dos system. UNIX is an existing system, which is not the same as developing a new system.

Developing East-Dos was like drawing on a blank sheet of paper. Don't worry too much. Developing a new version of UNIX is like dancing in shackles, and requires an in-depth understanding of UNIX, which Hong Kong does not have the talent to do. After the continuous expansion of Dongfang Software's U.S. R&D center, the number of engineers has increased to more than that of the Hong Kong headquarters.

Responsible for the follow-up development of the East-DOS operating system, East-dbase digital jù library software, and the development of the new East-Unix operating system. The Hong Kong headquarters is mainly responsible for the follow-up development of a series of office software.

Once the operating system forms a market monopoly, its importance is far from being comparable to other application software. Li Xuan's division of labor with Dongfang Software Company can be regarded as a rainy day. It will give some people more peace of mind and reduce their excuses for future attacks on Oriental Software. And in Li Xuan's plan. Dongfang Software will also go to NASDAQ for listing in the future.

Compared with AIPC industrial computers, another user of the East-Unix system, the workstation computer of Aikang, is also under intense research and development. Another name for a workstation is a server, and it's more powerful than a regular personal computer.

The most famous workstation computer on the market today is the Apollo Computer Company, which uses the Motorola MC68000 processor.

The performance of ERM-1 developed by the Oriental Research Institute was a little rudimentary, so Li Xuan did not plan to use the ERM architecture to build a workstation computer, but set his sights on the MIPS architecture jointly developed by the Oriental Research Institute and Professor Hennessy of Stanford University.
