About my impression of English education in China

This was a serious question for me how to use ‘though’ or ‘then’ at the end of a sentence.

Cos all of my English teachers did not teach me about it before. You can see that at least in the period of my studying in China, the education system, the schools and the society did not pay more attention to improving students’ oral English skills. I can remember that before I attended my college, there was only one very odd method to do oral English practice, which was reading the English articles, together, in almost every morning. And the teachers always mainly focus on teaching English words, grammar and even the skills for answering questions of exams. Cos there is a very important exam series happens every year and the English exam only consists of listening, reading and writing, NO SPEAKING. Of course, every student would like to have a high score, so speaking? how cares. Even in my college academic life, every English exam has the same situations. Until I was preparing the IELTS exam, I found that it was so difficult for me to speak English. Maybe it was my fault, I did not study hard, while the English teaching style in China was definitely wrong, even if there are several reasons which lead to this result I could understand.

Anyway, now I can grasp that

though: however

then: therefore

when they are placed at the end of a sentence.

E.g. I really like living in Xiamen; there are so few opportunities to find a profitable job there though.

Notes of Eigenfaces

One of the assignments of Computer Vision course is doing a group presentation about a specific paper which employs a face recognition technique. So the paper my group has to introduce is “Eigenfaces for Recognition”, which was published in 1991. At that year, I was born:).

In order to understand the process of how to use eigenfaces to achieve face recognition, I took some notes about it by drawing. Like that:

There is the simple process of how to use eigenfaces to represent a specific face image.

CampDigital 2019

I have to admit that the foreign educational environment offers many opportunities to engage with professional activities. Camp Digital is an inspirational conference that brings together the digital, design and UX communities for a series of seminars exploring the latest thinking in our industry. #2019/06/12

In my previous work, I was not a coder but also engaged in application design including functions, UI and UX. But actually I am not professional enough to do these work cos I only rely on my experience and personal thinking. Fortunately, it’s not bad. So I am really interested in this area. In my opinion, these are the work of art in IT. Wonderful!

The first topic for this event is quite interesting. Taking the US election method as an example, some election questionnaires and methods were compared. Actually, I am not familiar with the election. AND DON’T ASK THE REASON LOL. However, it can be understood that the more products or services the user is facing, the more complex factors are considered in the design. So the most critical, or the only thing that can be done, is to meet the needs of most stakeholders. For example, when an election is held in a country where almost half of the citizens are not good at reading, the questionnaire is full of massive words is not a sensible design.

The contents of the morning were very interesting. The second one mentioned the products of Disney. But the most impressive idea for me is: DO NOT THINK WHY IT FAILED, BUT WHAT CAN DO NEXT. This is actually very easy to understand the empirical theory, but in many cases, it will always focus on how to find reasons for failure. After all, failure will bring losses, and doing so may bring some comfort. BUT the next is always more important.

When I had lunch, I met a girl who looked young but already working. This was a free lunch! She is engaged in UX research at a consulting firm. Unlike my country, in the UK, there are many IT consulting companies. I also discuss this phenomenon with my tutor before. In my opinion, the reason why IT consulting companies are not popular in China is the situations of the progress of each industry. IT itself is a service industry and it can help other industries improve producing efficiency and innovation progress. So comparing with the situations of industries in these two countries, it’s more long-standing and stable in the UK while it’s developing at a rapid pace in China. Now, this is the stage of the rapid development of the IT industry, so the way to directly combine the main business with IT is to comply with this trend. By contrast, in the UK, professional companies are more trustworthy.

Unfortunately, I was too tired to attend all the seminar in the afternoon. But this was a really excellent and impressive experience for me!

Spaghetti Problem

This content is from http://www.alethis.net/mpotd/mpotd.php?id=00131

You have a plate of spaghetti in front of you (no sauce!). You pick two ends and tie them together. Then you pick two more ends and tie them together. Continue until there are no free ends left.

If there were n spaghettis originally, what is the probability that you now have a single giant loop consisting of all the spaghettis?

Pick the first end at random, from the 2n ends. When you pick the second end, you have 2n-1 choices, and exactly one of them (the other end of the spaghetti you chose) will create a loop at this step. The probability of creating a loop at this step is therefore 1/(2n-1), so the probability of not creating a loop is (2n-2)/(2n-1).

If we don’t create a loop at the first step, then at the second step, we have the same situation, but with 2n-2 free ends. Pick one end at random, and the probability of forming a loop at this step is 1/(2n-3), since there’s only one other end that is attached to the end you chose. The probability of not creating a loop at the second step is therefore (2n-4)/(2n-3).

When we eventually get down to two remaining segments, the same logic applies: pick one end, and of the remaing three ends, one forms a loop, while the other two allow us to proceed to the last step, where a single giant loop is formed. The probability is 2/3 of not creating a loop at this second last step.

To end up with a single loop at the end, we must not create a loop at any of the intermeditate steps, so the probability of this is:

2n – 22n – 42n – 62
2n – 12n – 32n – 53
=2n – 22n – 22n – 42n – 42n – 62n – 622
2n – 12n – 22n – 32n – 42n – 52n – 632
=4n-1(n – 1)!2
(2n – 1)!

The first few probabilities are:

22/3
38/15
416/35

About Avengers Endgame

This is quite late actually, I was busy in my study, my anxiety and my life. But there is no doubt this is a special period of my life. After those busy days, I had a time to watch this movie finally. No pic, No details, just tear.

When I was a undergraduate student, the first movie of Marvel, Iron Man, was on. I was curious because of his because of his handsome face, his all boys dream of steel armor. At that time, I was like tony, regardless of the life. I felt that no one in this world can understand me, and no one can feel my troubles. My distance from my father was so far away, my dreams with me was so far away. During these 11 years, I have forgotten those who watched the Marvel movie with me, Iron Man, Captain America, Spiderman, Ant Man, Avengers. Dazzling, all passed.

I am so touched by this movie. After it, I told my fiend that I was crying several time during it. She said She said that she was also touched by the scene of the gathering of all the characters. But for me, it’s because the deep feeling of my life from the deep heart. I recalled that when I watched Iron Man for the first time in 2008 which he said “I am Iron Man”. These eleven years are like flying through the gaps, so I can’t believe that time is so ruthless, so that I can’t completely remember everything that happened during this time. Util he said it again with his gone. I hate that I have forgotten the pain and happiness I have experienced in these years, but I am happy for every unexpected experience I have experienced.

After that movie, I talked with my friends about the detailed story of it. They said they were all crying at that time. I believe there is a superhero dream in the heart of every boy. We wanna become a superhero to save the world, we wanna everyone can remember us. But on the road to growth, we lack ourselves to lose these dreams again and again. I am so sorry for my friends who are sincere, my families who really care for me, my lovers who put me in their heart. I am so sorry.

Like I said, I am not a boy any more. There is a tough way that I have to go. And there is not a life I expected. The only thing I can do is try my best to get it instead of hating it. For the tomorrow, for the future. I drunk three bottles of beers, and I will try my best to love you three throunds.

关于一篇发生在两年前讨论SAME的文章的个人想法

Image from: https://huaban.com/pins/1538216189/

该文章发布于2017年,内容是讨论same为何还不火而提出了几个该作者个人的看法和解决方案。而我一时兴起,在留言中针对文章内容也提出了一些自己的观点。

文章链接:https://coffee.pmcaff.com/article/921679014652032/pmcaff?utm_source=forum

以下是我回复的内容:

因为最近same好像停服了,想知道具体原因结果搜到这篇文章。 冒昧针对文章中的各点说一下自己的想法: 1. 作者也在评论里提到,same作为一个另类的社交应用,它的用户并不想大程度地在自己已经成熟的社交圈里推荐same或者分享same中的内容。核心用户的诉求是想脱离诸如微信,微博此类大众且熟人社交模式,在一个新的社交平台上发布区别与朋友圈或者微博中发布的内容并且认识兴趣或者想法一致的陌生人。既然产品的目标用户已经如此明确,为何要在用户自发传播上下力气呢。再则,个人并不赞同文章中经常提及的加水印的做法。真正吸引新用户的是内容,内容的质量又是基于应用功能和用户本身。换句话说,只有内容足够吸引人,水印才能发挥效果。水印只是自我广告的一个点,并不足以大程度解决增加传播度的问题,更何况same的用户都不想往外传播。针对文章中解决方案的低一点,same在产品初期的内容质量十分出色。而针对您提到的在初期增加内容长度以及多样性很有可能造成功能过剩和易用性降低的情况。

2. 这个问题十分有趣,个人并不认为same的玩法过少,反而觉得以same核心功能为基础,能发展为十分全面的社群。而最主要的手段就是运营。same以频道区分内容,且每个频道的内容类型也是固定,这很大程度上提高了用户对内容的针对性,就像把传统的标签当作了最重要的索引。频道起了两个大作用:将用户的兴趣具象成内容类型,且聚拢相同兴趣的用户。但问题在于same官方并没有过多参与管理内容中,这也导致了重复性质的频道过多,后期内容质量降低等情况。再从功能上来看,第一,same提供了语音,文字,图片,视频,甚至投票的形式呈现内容,恕我无知想不出除此以外的方式。第二,每个频道对内容的交互方式也是固定的,只能为“直接私信作者”和“评论留言”其一。个人认为优势已经十分明显,不仅降低管理成本,而且提高了用户浏览内容时的体验。最后想针对文章中提到的“对于一部分追求“性”的用户来说,yuepao无果后,自然也就离开了这个平台”。这样的结果难道不是最好的吗?剔除低质量用户对same还是samer来说皆大欢喜。

针对其他几点恕我同样不敢苟同。面对一个产品时首先需要明确产品核心功能和用户定位。我想文章中提及的诸如增加传播度,增加玩法,提高包容度甚至成长体系已经完全与same相违背。之所以会有千万级别的用户群被same所吸引,我想并不是因为这些用户想去到一个名叫same的微博社区。同理,已经有千万级别的用户量了为何还要把问题放在如何吸引更多的用户上?我想这也是same今天停止运营的一个原因,如何维护已有用户理应成为需要解决的首要问题,而第一个切入点只能是内容。同时比较赞同KONG8691评论的后两个问题,内容和变现。最后想吐槽一下same的IM功能,虽然比起早期已经优化了不少,但是还是很难用啊!有多少人因为一直发不去信息才转去其他IM应用!以上包括前两条评论内容纯属我自己的胡扯,谢谢

25th Feb. 2019

The weather in Manchester is really excellent recently, while I hear that there is always raining in most coastal cities in my country. And this is my first diary in this blog because one of my best friends asked me to write down what I thought and what happened today.

My Recent Situation

This is the first time that I have not been with my families to celebrate the Chinese Spring Festival. Before the end of the previous year, I ended all the content of the first semester, including the exam; completed the release of the test version of the application I was responsible for. In short, there have been many happy and sorrowful things in 2018. And recently, I thought I would have a better academic life in the new semester, but I was wrong. Actually, I do not have too many course units now, while I still feel pretty stressful because of mindfulness for concentration and perfectionism. In addition to the course study, I also need to start preparing for my project of the master’s degree, applying for a job and planning a new idea that has just emerged today — self-employment.

Venture

I should thank two of my classmates who had dinner with me today. In the chat after that, a very interesting idea suddenly appeared in my mind. This made me thought seriously about how to make the idea become a real business all night which I had no idea before, especially in a foreign country. Because self-employment sounds like a very big challenge for me and I don’t think I can consider all aspects well and plan well and execute well. But I think the reason why I was diffident is there are no concrete ideas and clear goals in my mind before today.

The first thing I can think of was to verify the feasibility of this idea. My initial plan is to set up the business in the UK instead of China because of the market and environment. Of course, I cannot handle it along in order to various factors and industries it relevant. Moreover, I can clearly know that no reward would be got until making it become real. Even if I can approve it’s very beneficial to do business based on this idea, I still need to do some survey, analyse data and write business plan to treat this behaviour as a venture. There is still a long way to go.

So for now, there are several key points I have to do or to address next showed the Eisenhower Decision Matrix.

Aim in Mind

The first people I can think of that he/she can help me perhaps is one of my teammates in the previous coursework group. He has got his bachelor’s degree in the US and he is studying in MBS now. That’s quite good because of his English skills, thinking patterns and also study background, even if no work experience. After around 1hour talking, he told me that he still insists to work in China after graduating with a very clear aim. On the other hand, my other good friend has been hesitating to choose where to earn a PhD. Because of the programme she is studying, studying for a PhD degree is a very good choice. But for various reasons, such as age, marriage, expenses, etc., this goal has not yet been firm for her.

For young students who are graduating, it is very difficult to make the right choice for the future plan. Principally, no one can guarantee which choice is “correct.” Normal students cannot rely on experience to make decisions, except for a small number of students who have some work or other experience. In addition, people also need to consider the impact of various factors when making a judgement for their future. At this time, interests and ideas become an important support for a firm goal. After all, human always gets answers about life in constant trials. In this way, I am very supportive of the choice of interest.

Happy Talking

I need to especially thank the good friend who asked me to write this diary. Because of the jet lag, I didn’t communicate with her about the idea for self-employment until midnight. What impressed me the most during the conversation was that the improvement of abilities and skills brought about by the work was more significant than the simple study. Of course, we only discuss which way is more conducive to the development of professional capabilities. We also roughly compare the market environment of several countries in different regions and the development of the IT industry. In addition, she helped me solve some of the important or unimportant issues I have encountered recently. Thanks again for her help.

Suggestions for my delimma

Next, I wanna talk about the most serious problem I have met these days and I still did not tackle it well, which is perfectionism. Actually, this is a problem that I have always had, and I have always been aware of the existence of this problem, and I have never thought of a good solution for it.

The reason why I have paid attention to perfectionism until now is that it has brought a particularly adverse impact on my academic life. For example, the content of a course unit in the last semester is quite related to my previous work, so I really want to present many of the situations I met in my previous work in the final essay. But in fact this is a very difficult process of thinking. In the process of writing an essay, I found that the basic knowledge involved in the lectures was not enough to support me to critically evaluate the problems I have encountered before. I need to spend a lot of time reading enough literature to cope with and explain them. I hope that I can make good essays or projects with my own strengths, but it is unrealistic for my current ability to meet my high requirements. So the final results were often much lower than expected, which makes me feel quite depressed.

My friend’s suggestion for this problem is that I should rationally list the tasks that need to be completed during the stage of planning and set reasonable deadlines for each task. In other words, the first and most important step is that I need to focus on the plan. Rationally thinking of the feasibility of the task before setting a goal for yourself, and then make a plan based on the results. I believe this practice should help me if I can do it.

Satisfy my cuorisity

My curiosity refers to the operation patterns and social responsibility of some Internet media companies in China. These are sensitive content.

Making CV

Finally, I would like to figure out how to write a CV for applying for a job. Although I have been working for several years and have had a lot of recruitment experience, I have actually not participated in a job interview for a very long time. Moreover, I would like to know more about the requirements of CVs for large-scale technology companies in China and other countries. Because my friend has had some interviews with world-renowned companies and is currently working for a very famous technology company in China, I believe her suggestions.

If it is used for interviews with domestic companies, the basic structure of the CV is as follows. Basic information; personal summary; work experience, project/programme/portfolio experience; education; skills; personal interests; interests for the company.

As she said, domestic companies seem to focus on the interviewer’s actual work experience, while foreign companies want to know the interviewer’s personal abilities and skills from details. Therefore, if a CV is prepared for the interview of a foreign company, the order of the content may need to be adjusted in the CV, while the above structure should be applicable to all situations. In addition, the interviewer also needs to pay attention to the format and layout of the CV , as well as the number of pages.

Good Night

As you see, this is a very informal diary. I did not talk about the detail of my idea but the thoughts I got today. And now, writing blog frequently is still a tough job for me but I need to try to keep this habit. Have a good night:)

‘frac’

Syntax

frac(x)

Description

frac(x) represents the “fractional part” x-floor(x) of the number x.

For complex arguments, frac is applied separately to the real and imaginary part.

For real numbers, the value x-floor(x) represented by frac(x) is a number from the interval . For positive arguments, you may think of frac as truncating all digits before the decimal point.

For integer arguments, 0 is returned. For rational arguments, a rational number is returned. For arguments that contain symbolic identifiers, symbolic function calls are returned. For floating-point arguments or non-rational exact expressions, floating-point values are returned.
