Geekband next week offline classroom

Today, the next week of Geekband's offline class, feels like it's been a long time since last week (because of the constant exposure to new knowledge, new ideas, team building, running-in, project brainstorming, and eventual establishment) for the rest of the week, the 8-week offline class has gone 1/4, So it feels like time is passing by. This is the reason I like the internet industry, because the rapid development and iteration, will make an ordinary person's working life of decades, in the process of continuous learning and updating their minds, to experience more wonderful, there are successes, passion, there are failures, confusion, in virtually lengthen the breadth of our lives.

Not much to say, to review today's Geekband offline classroom.

First, the product manager of the course of the Yuan shop Ming teacher's product review Link:

1. This is the first time to see teacher Yuan, in the classroom online live before the start, Yuan teacher just beside me, on our project team idea on the product manager Zhang Cheng "copy" asked, my first impression is that Yuan teacher's question is very clear and powerful, with a force, if you do not fully consider their idea, A few problems are generally overwhelmed. But it is also the charm and value that allows you to think deeply about your idea and find the blind spot you didn't think of before.

2. Teacher Yuan also shared his product concept: logical deduction is very important, if you want to improve the logical ability, there is a book is his recommend-"Introduction to systematic thinking."

3. The demand is not equal to the problem, the user is confronted with the actual problem, so it will have the demand for the solution, but not I think the user has this "demand".

4. The language expression, the expression ability, is very important, can 1 minutes to convey the thing that you want to express to the audience accurately, clearly, or you want to convey the object. An iOS student at the scene expressed their group's project very clearly and well, although he was not a product manager. This also shows that the engineer experienced the logical thinking is very useful, the logic is clear, the expression of natural clarity; if one thing you can not say clearly, it is probably not the problem of eloquence, but the brain lazy, not to think clearly.

5. Do the logic deduction first, then to find the target user to conduct interviews, research, and distinguish the user's meticulous degree, but also indicate how deep your thinking, if the reverse, for example, do not choose to find a bunch of "users" to investigate, you may be brought into the ditch by users.

Second, the iOS course Chessong teacher to the offline classroom scene, also carries on the online live interactive:

1. Watched a few days of iOS video, Chessong Teacher's lecture style is very fond of, so caught some time before the broadcast, Het teacher chatted, also asked a few questions. One is about the objective-c and swift language in the study of the focus, Duan teacher also from the perspective of the actual development of enterprises, nearly two or three years must still need to use a lot of objective-c, so we must first learn objective-c. Also hope to have tangled in Apple now between the new and old two languages of classmate, can relieve doubts. Of course, this is the beginning of an operation above the consideration, after all, time and energy is limited, and as Tinyfool teacher said, the road of engineers is useless, any good engineer should be full stack. So there is no use in any language dispute:)

2. Do not memorize, because rote memorization is useless, but because of the situation can not remember the confidence of the attack. Einstein also said something similar: I can find the information, I will not waste my brain to remember it, when used to check on the line. (When I went to school with my classmates than the back of Pi drift ~)

3. Do not end up in the end, so many people say that a teacher is not like a programmer, because he said do not want to just stand in the programmer's view of the program, in fact, the user care, the company is concerned about the product itself, not how your code is written, how good, these are just means and tools, not the goal itself.

4. Get the product requirements document, do not rush to write code, paragraph teacher to share their experience is the need to read the document carefully 5~7, and then can unscripted and product managers and other project team members to open a meeting, both sides communicate clearly after each other, and then began to write code, is so-called AX. Get the demand immediately start coding, usually novice.

Third, Geekband founder Li Jianzhong teacher to explain some of C + + knowledge, as well as online live interactive:

1. Do not point the pointer to the Stack object, which is very dangerous, because the function is finished, the objects in the heap will be destroyed.

2. Draw the memory model, teacher Li generally began to teach you to draw a memory model. Otherwise will only be proficient in writing programs, but once the problem, especially complex problems, will be flustered, no clue. And it's very helpful to be an all-stack engineer and switch various languages.

3. The Stack object holds the pointer, but the object pointed to by the pointer is stored on the heap.

4. It is important to figure out how big an object is, how much memory is used, such as the sizeof () function. Not for the interview to become a test preparation, but because the interview is sure to ask important questions, so this to their own programming skills to improve is also helpful.

Four, but also our play in Geekband-the promotion of Project practice

1. Our project team's products have also been identified, the core of idea is to intercept 1 seconds of video a day, a year can be aggregated into 365 seconds (about 6 minutes) of the video, the user initially located in the parents with children, to record their children's growth trajectory, growth moment, from the birth of children, to a little grow up, I believe that after This will be a very precious gift, not only the video itself brings the move, but also the video behind every second, there are parents and family to ta poured love. (Think of this, I want to have a child, how to do:)

2. The first time to do the project, always indecisive under the hand, it seems that he is not ready, but came to Geekband is to swim in person, to learn how to swim.

3. Here, using Churchill to learn the story of painting, to encourage himself and my friends with the same situation: "I (referring to Churchill) with their toys watercolor dye a little bit of a try, it prompted me the next day to buy a set of oil painting equipment." The next step I really did. The coloring of a beach on the color palette, a new white canvas in front of me, the color of the brush as heavy as weight, death, hanging in the air. I carefully dipped a tiny brush into a really little blue pigment, and then gingerly painted a little bit like a small bean on the aggressive white canvas. It was only then that a car was heard in the driveway, and the car was not someone else, it was the famous portrait of Sir John Raivery's sparkling wife. Painting But you still hesitate what yo! Give me a pen. Be big. "The paintbrush dipped into the turpentine, then threw it into the blue and white pigments, stirred wildly on my palette, and painted a few blue on the trembling canvas." The Magic spell was broken. My morbid restraint has vanished. I grabbed one of the biggest brushes and valiantly poised to my victim. After that, I was no longer afraid of the canvas. ”

In iOS development, Churchill buys a "whole set of canvases" Just like the Mac computers we bought for iOS development, so to get your canvas dirty, some wonderful apps are coming from your fingertips and on your Mac.
