Feng Nuo is currently reading a post on BBS: "If there is another wormhole, will you go back?".
This is a menstrual post on BBS. However, in recent years, not only are fewer and fewer people on BBS, but the number of people on BBS is getting less and less. There are also fewer and fewer replies to this post. It doesn’t last more than ten days and a half.
There is no new reply. Of course, this is not unrelated to the overall cooling of BBS. The enthusiasm of the veterans for BBS has dropped significantly. Not to mention commenting on posts, there are very few people who open posts.
In the past, the grand occasion when a post about "senior power" could reach thousands of floors has disappeared. Firstly, the elders are busy with their affairs and have no time to argue on BBS. Secondly, everyone's reputation is getting bigger and bigger, and their power is getting heavier and heavier.
, it would be "losing one's identity" to talk nonsense on BBS. So proposals, memorandums, notifications... these official documents with different names replaced online discussions.
Because Feng Nuo manages the computer room and also serves as the BBS administrator, he goes up from time to time to check and maintain the forum's database. He also checks to see if there are new posts under this post, but he never speaks on it. In fact, until
A few months ago, he felt that his answer was still "yes". But he would never say it out loud - other people's replies might just be chatting or venting dissatisfaction, and he would never show any "wavering of revolutionary will".
He stared blankly at the BBS for a while, thinking about what answer he would give now. For the first time in the past few months, he felt connected to the world. He stayed connected, held meetings, checked information all night, and reviewed 89% of the information he had forgotten.
The purpose of college textbooks is just to add a few words when discussing design plans with robotics veterans. This is a fulfilling feeling that was never experienced in the old time and space.
"So this is how these red-faced guys feel!"
A gurgling sound in his stomach interrupted his thoughts, and he turned his attention to the materials on the desktop. As the computer project progressed, his desk became more and more messy, filled with documents coming from all directions.
Just reading them all made Von Nuo feel exhausted - there were too many things that needed to be coordinated, and he now fully understood why the instructor was "not doing his job" all day long.
It's a pity that I don't have any graduate students under my command...
The first report is the trial report of the punching machine. The punching machine has been put into use for several weeks, and pilot census work is currently being carried out in Lingao and Qiongshan where the grassroots conditions are good.
Of course, the census results cannot just be stored on punch cards that are not reliable. In fact, they are still in the form of a "Resident Population Registration Form" filled in by census personnel at each household. The census results of each street or commune are then unified and "punched".
". Although the material strength of the punch machine is insufficient, the damage rate is high, the card quality is poor, and the training time of the naturalized staff is short, in practice, the rate of discarded cards once exceeded more than half, but the entire census work has been basically completed.
.In order to cooperate with the subsequent development of tabulation machines, the "Permanent Population Registration Form" and statistical results of several streets were transferred to facilitate proofreading and verification. All data were moved from the Ministry of Minsheng and temporarily stacked in a room of the Machinery General Factory.
In the warehouse.
The card feeding and transmission system has now been developed. Under manual control in the laboratory, the current card feeding and traditional systems can already read cards one by one, send them to the processing unit at a uniform speed, stop accepting processing, and send them out for processing.
Only limited by the quality of the cards, the transmission speed is still very slow, and paper jams may occasionally occur. This system is a common basic system for the subsequent development of tabulating machines, sorting machines, and copying machines. The so-called
The sorting machine drives different card sending mechanisms to send cards to different card pockets based on the read punching information in multiple processing units connected in series. The so-called copying machine is two sets of transmission-processing systems, one of which
The processing unit of the processing unit is responsible for reading the punch information of the punched card, and the other processing unit is for punching holes in the same position for the new card. The tabulation machine/accounting machine performs basic statistics after the processing unit reads the card.
Rely on programmable wiring holes and even control cards for digital-character conversion operations.
This part has little to do with the source of power. It is more about the design and development of the mechanical structure. If the electric method is used, the stability of the transmission will be stronger and the accuracy of card feeding will be higher. Of course, the electricity is also carried out through relays based on punched cards.
The premise of automatic control is that the design of an electromechanical control system is much simpler than a purely mechanical control system. Feng Nuo can barely handle it himself, but for a fully mechanical control design, he may have to ask others for help. This is Feng Nuo.
Reluctantly.
The next step of the research team's plan is to develop a tabulating machine. The tabulating machine can be roughly divided into two functions, one is data statistics and calculation, and the other is the output structure. Needless to say, data statistics and calculation, the "calculation" of a mechanical computer
The two words fall here, it is a subject that must be solved; the output structure involves another big project, the Chinese typewriter system. The mechanical port once imitated the Chinese typewriter, and the result was limited compared to the hand-cranked computer project.
It is basically usable. Moreover, because it cannot solve the problems of typing efficiency and memorizing word lists, Chinese typewriters are not popular in the old days. Except for necessary official documents and printed matter such as books and newspapers, they are not more convenient than handwritten mimeographs in ordinary situations, far from it.
Compared with English typewriter.
However, the automatic typewriter system is still very attractive. Not only does it eliminate the difficulty of manually memorizing word lists, but if the automatic control system passes the test, the efficiency of picking words will also be greatly improved. Feng Nuo even used the free time of the management computing center to add characters to the dial.
The layout of the table has been re-optimized. The Chinese encoding scheme adopted some time ago is based on location codes arranged according to pinyin. The layout of the characters on the Chinese typewriter dial is mainly classified by radicals. This is all adopted to facilitate people's memory.
The arrangement method. However, there is no need for automatic typewriters. It only needs to be arranged with the goal of "minimizing the expected average moving distance of the fuselage during the citation process". Therefore, Feng Nuo based on the massive amount of data extracted from the data center
The corpus calculated the transition probabilities between commonly used characters and constructed a huge Markov model. It took two or three months to solve the problem in the computing center before coming up with an optimized character disk plan. Feng Nuo estimated that
This solution is 30% to 50% more efficient than the dials used in the old days. Of course, it is completely impossible to pick up the letters manually.
Feng Nuo excitedly took the plan to the people in the Chinese typewriter project team to sell his idea and asked for cooperation. As a result, he was quickly doused with a basin of cold water. The Chinese typewriter project team was a group of veterans of the mechanical industry, no matter what.
Currently or in the foreseeable future, he has no intention to electrify or automate Chinese typewriters. These people generously introduced a lot of relevant information and experience to him, and also took him to see the models and prototypes. However, Feng Nuo
The plan must rely on a complex wiring structure to convert the location code into dial coordinates, and then calculate the moving distance of the fuselage based on the current coordinates, and accurately drive the motor to achieve the goal. Although Feng Nuo does not understand electromechanics, he also knows that this thing is not in technology.
The position on the tree cannot be reached in just a few years.
After this setback, the research team organized several discussions on the Chinese output agency. Finally, it was considered difficult and decided to postpone the development and focus on the card information statistics function. At most, it could simply create an automatic number.
The print function serves as the output mechanism.
The statistical function of the card can be divided into two schemes. One is to make several accumulators based on the advantages of the electromagnetic storage mechanism over the purely mechanical storage mechanism; the second is to use the mechanical storage mechanism of the hand-cranked computer, and the relay is only used for
Automatic control. More complex operations are completed through the combination of multiple classification machines/accounting machines.
Of course, Feng Nuo prefers the first solution, and it is difficult to ignore the advantage of mechanical storage being simpler to implement at this stage. However, no matter which solution, the electromagnetic control system cannot be bypassed. The veterans of the research team each
They all have their own problems. Although professionally speaking, Faraday and others are more suitable for the development of relays than themselves, but a few people can meet together to come up with ideas. As the main research team, there is no time. The veterans of the power outlet are now focused on developing generators.
, electric motors and other high-power systems, and relays are not yet on the schedule. If Fonnuo wants to quickly advance this project, he will have to tackle this technical difficulty himself.
There was a cautious knock on the office door.
"Come in."
At this time, Feng Nuo noticed that Feng Shan came in, with dark circles under her eyes, and asked: "Are there extra classes in the morning?"
He remembered that there were no classes scheduled at Parkview this morning.
"A temporary course." Feng Shan said.
This kind of thing is very common. The class schedule in Fangcaodi belongs to the four major firms. But Feng Nuo had a doubt in his heart. He felt that Feng Shan seemed to be hiding something. This thought passed in a flash. Because he suddenly
I noticed that my maid was wearing the uniform issued by the office to the life secretaries today, commonly known as "maid uniform". Because she had to take part-time classes at Fangcaodi, Feng Shan almost never wore "maid uniform". Why did she think of wearing it today?
Is this it?
Unlike many maids who like to wear this uniform to show off their "different" status, Feng Shan does not like to wear maid uniforms, and is even a little resistant. Feng Nuo generally does not force her to wear whatever she likes, and he
Not a maid-controller.
The reason shouldn't be that there are too many dirty clothes that haven't been washed or replaced - the service agency provides laundry services. Feng Nuo is very considerate of Feng Shan's busyness and hard work. Many menial tasks are outsourced to the service agency.
However, he didn't have time to delve deeper: "I need to clean the house at home. I've been very busy recently and can't take care of it at all."
