Lin Manman "retreated" for two more days, with the help of the "Ruyi Pad" in his mind—for the time being, call it that—powerful performance and rich documentation,Lin Man completely got the intelligent pinyin input method,It can run normally under DOS。 The reason why it takes extra time to debug is that DOS limits the regular memory to 640K, and large programs simply cannot run without memory optimization.

At the same time, Lin Man completed a C program editor that he had been planning for many days. The most popular C development environment is Borland's Turbo C/C++, which is almost unified, and there is nothing to do with Microsoft VC. Due to the limitations of the DOS system and hardware performance, the current program development environment is not only simple in function, but also a pure character interface, with low resolution, red and blue as the main colors, and the appearance is completely incomparable with the three-dimensional interface under the Windows of later generations. Lin Man modeled on the later Notepad++ and Edit Plus, and wrote a program editor with a graphical interface, which not only has a simple and beautiful interface, but also adds many functions that the existing editors do not have, such as automatic indentation, automatic folding, automatic code generation, automatic prompting of variables and functions, multi-window switching to edit multiple source programs at the same time, and so on.

Lin Man was also tired enough, but he had a sense of accomplishment, because these two software were written by himself, not "take-it-ism". As a senior programmer, Lin Man has his own pride. Of course, most of the programs in the "Ruyi Pad" cannot be directly exported to run under DOS, one is because it is not the DOS version, the program is incompatible, and the other is because of the high hardware requirements. However, the mini-games in the DOS virtual machine in the "Ruyi Pad" can be exported directly and played on the 386 computer.

Lin Man, who looked haggard, was in the office of the service center, listening to Li Xiuli complaining that the noodle brother he recruited was too ugly, although the speed of cutting vegetables was a top one, but it would still affect her mood. Lin Man turned a deaf ear and handed her a packet of brown sugar.

Well, there are a few days a month when you are in a bad mood and pick and choose everything. The brown sugar was bought by Lin Man on purpose. When he subconsciously walked into the store, picked and paid again, Uncle Lin Man was still flustered for 2 seconds, and couldn't understand why he wanted to buy brown sugar, and then he reacted, Lin Man actually took the initiative to help Li Xiuli buy a bag of brown sugar every month. Uncle Lin Man couldn't help but slander, this Lin Man classmate is strange enough, and even knows other people's menstrual cycles. Of course, the benefits of this are also very straightforward. Lin Man drank the chicken soup that Li Xiuli specially stewed for him. In terms of being considerate and caring for people, no one can compare with Li Xiuli, and neither can Zhang Yan, then a big lady.

Lin Man happily said nonsense: "I said Little Apple, you are becoming more and more like my wife now, not only will you be considerate of my hard work and strengthen my nutrition, but you will also collect my salary and prevent me from spending money indiscriminately." ”

Li Xiuli raised her hand and smashed a white object. Lin Man caught it in a chic manner, took a big bite, and praised: "Well, it's juicy and stuffy, and the food is a big meat bun, you deserve it." What my brother eats is not nutrition, but what my brother eats is affectionate care. ”

Li Xiuli has no good way to take this scoundrel, as if she owed him in her previous life.

Lin Man, who was well-fed and well-fed, performed the scoundrel Dafa, and finally got his first month's salary in the service center, which was actually 1,000 oceans and developed. After grinding a few large food coupons with Li Xiuli, Lin Man patted his ass and left.

Lin Man first went to the Youth League Committee to find Secretary Zheng and Secretary Luo, presented a meal coupon and questionnaire, and asked the leaders to give valuable opinions on the diet of food for the day, and by the way, listen to the teachings of the leaders, and swore that they would never beat people in public in the future, and then went to work in Qirui Company.

Lin Man originally thought that Secretary Tong urged him to go to work because he had work to do, but the general manager of the family prepared a gift for him and specially equipped him with the latest 486 compatible machine.

When Lin Man advanced half a year's salary to Secretary Tong, he suggested that he talk to CCB about service outsourcing. Secretary Tong didn't expect much, but he didn't expect that after talking with the information department, he easily signed a maintenance service contract for system maintenance and inspection with a total amount of 200,000 yuan. Director Zhou of the Information Department is also a very thoughtful person and is willing to do an experiment. Although the hardware must still rely on the original factory, the daily maintenance of the software, the inspection of system logs, and preventive maintenance can be outsourced. If successful, the annual savings in service costs will be considerable, which will be an important achievement for his work. No matter how rich the bank is, there is no food left. Director Zhou may not be so confident in Qirui Company, but he is very confident in Lin Man, Lin Man's performance that day was too amazing.

It was precisely because of the successful signing of the service contract that Secretary Tong generously spent nearly 20,000 yuan to configure this computer for Lin Man. Lin Man is a transcendent existence in Qirui, since he joined Qirui, he has never worked, let alone done serious work. Secretary Tong didn't care at all that he was getting his salary for nothing. A Unix master like Lin Man, one or two shots a year is enough to help the company solve big problems. Now that he hasn't made a move, he has signed a service contract of 200,000 yuan, and the cost he paid is just Lin Man's salary.

Seeing that Lin Man was still unmoved in the face of the top-level configuration of 486, Secretary Tong and Manager Tong couldn't help nodding secretly, Xiao Lin Man did have a master's demeanor. The two graduate students who were doing development next to them were far behind, and their saliva was about to run down when they touched the new machine.

One of the two graduate students was Brother Tang, whom he met when he moved to CCB last time. Lin Man admires this Senior Brother Tang very much. Brother Tang's father, he and his younger brother, all three of them are inventors, and the father and son have more than a dozen officially authorized national invention patents.

Two graduate students are developing a phone banking project that provides voice banking services to customers who call. Secretary Tong said casually: "Lin Man, you help them take a look, there are a few problems that they can't solve." That's what he said. He is also a computer student, a person is proficient in system operation, not necessarily proficient in system development at the same time, not to mention telephone banking, such a high-tech project with both soft and hard. In China, Qirui was one of the early companies to develop this project, and was a pioneer, but of course it also took more risks of failure.

Lin Man was very interested in this project and listened carefully to the introduction of the two graduate students. The main difficulty mentioned by Brother Tang is that there are too many lines for calls to be dialed in, the software does not respond in time, and it is not possible to replace the 486, which has a faster computing speed.

Lin Man helped them analyze that a major constraint is that its software is developed under DOS. Because DOS itself is a single-process system, it is difficult for the program to process a large number of call requests concurrently, and the polling strategy implemented simply by looping is only suitable for a small number of dial-in requests. It is recommended that they develop a multi-process concurrent processing system under Unix. Of course, the hardware needs to be changed to a minicomputer server, which requires a large investment. Unix, which can run on PCs, has just come out, and it is not yet mature, so you can only choose a small computer. If the bank is serious about this new business, it should be willing to invest in it.

Brother Tang said that he was not familiar with multi-process programming and did not know how to start.

This is easy to do, Lin Man took out the program editor he just developed, this software can automatically create various forms of multi-process frameworks. Lin Man named his editor ProgramMan, which is the most commonly used help command in Unix.

This editor, Lin Man didn't plan to sell it for money, but planned to use it to make a name for himself.

In addition, Lin Man began to plan to change his major, he didn't want to continue to study the current mechanical manufacturing major, if he could change to the computer department, he basically didn't need to study, and he could easily graduate with it. Lin Man has already selected several tutors in the Department of Computer Science in his mind, hoping that with a tutor who is willing to accept him and a tutor who helps, it will be easier to change majors. Of course, it is possible to directly find Mao Sui to recommend himself, but where is it natural to have an acquaintance recommend? Therefore, Lin Man set his sights on Senior Brother Tang, because his tutor was Professor Chen, a big bull in the Department of Computer Science.

Secretary Tong was very surprised to see that the editor written by Lin Man not only has a beautiful interface, but also has a unique function of automatically generating code and prompting variable names. Lin Man's program editor subverts his perception of the traditional development environment. In these years, domestic programmers who can independently write distinctive editors are all "gods", such as Qiu Bojun, the author of the Chinese word processing software WPS, and Zhu Chongjun, the author of the table editing software CCED.

But Lin Man is definitely the first person in China to independently write such a powerful program development environment.

I've really found a treasure.
