The Biological Effects of Father Loss: An Interview with Daniel Notterman

Dec. 22, 2019

Introduction

It is holiday season. I went to tennis court in central park, and also I met people. The tennis is such great sports, people bring their family on tennis court, so I  have chance to meet people and also their family. One of topics I like to look into is Father loss. My father passed away when I was the first year in the university, 1985, I was 19 years old. I like to look into the impact of the issue.

First time 30 minutes research

I like to read some article. I met a young Canadian lady and said hello. I believed that she missed her father. I still remembered 4 years ago, her father brought her first time on tennis court, she played tennis against the wall. The father told me that she will go to Albert province.

I play tennis double matches with so many people in central park. I had chance to know so many families and I like to look into this topic.

I like to reach out the community to help others, specially the depression is so easy to affect young people in the city of Vancouver area. The winter weather and other issues.

12 Cognitive Biases Explained - How to Think Better and More Logically Removing Bias

Here is the link.


We are going to be explaining 12 cognitive biases in this video and presenting them in a format that you can easily understand to help you make better decision in your life. Cognitive biases are flaws in logical thinking that clear the path to bad decisions, so learning about these ideas can reduce errors in your thought process, leading to a more successful life. These biases are very closely related to logical fallacies, which may help you win an argument or present information better.

INVESTING MUTUAL FUNDS Survivorship Bias

Here is the article.

What Is Survivorship Bias?

Survivorship bias or survivor bias is the tendency to view the performance of existing stocks or funds in the market as a representative comprehensive sample without regarding those that have gone bust. Survivorship bias can result in the overestimation of historical performance and general attributes of a fund or market index.

Survivorship bias risk is the chance of an investor making a misguided investment decision based on published investment fund return data.

KEY TAKEAWAYS

• Survivorship bias occurs when only the winners are considered while the losers that have disappeared are not considered.
• This can occur when evaluating mutual fund performance (where merged or defunct funds are not included) or market index performance (where stocks that have been dropped from the index for whatever reason are discarded).
• Survivorship bias skews the average results upward for the index or surviving funds, causing them to appear to perform better since underperformers have been overlooked.

成功学有用吗？幸存者偏差，一个活着就该明白的事！李永乐老师聊聊大牌球星的身价（2018最新）

Here is the video.

高考刚刚结束 世界杯马上就要开始了 有人看到的这些天价球员 梅西 C罗 就说呀 唉 我运气不好 没有当一个踢足球 否则我现在就像他们一样有钱了 事实上真的是这样吗 今天我们来讨论一下这个问题 我们首先从高考全国二卷一个作文题目开始讲解 二战 " 期间，为了加强对战机的防护，英美军方调查了作战后幸存飞机上弹痕的分布，决定哪里弹痕多就加强哪里。然而统计学家沃德力排众议，指出更应该注意弹痕少的部位，因为这些部位受到重创的战机，很难有机会返航，而这部分数据被忽略了。事实证明，沃德是正确的。 为充分解答这个问题 得先明白幸存者偏差是什么 幸存者偏差的意思就是说 你只考察了幸存者所满足的特征 这并不能得出一个有说服力的结论来 这个结论能解释很多现象 比如 淹死的拜神者 用了20年不钝的刀 验证药物疗效的双房实验 比如，我们看到世界杯上那些天价球员 梅西 C罗 内马尔他们，就以为踢足球都会很有钱 但事实上中国许多球员工资还不到10万元 还有许多人研究成功学 从许多成功人士身上找到共同点 但却忽视了那些也具有同样特征的失败者 等等 反正就是 幸存者偏差，一个活着就该明白的事！

Understanding risk in career

Dec. 22, 2019

Introduction

It is a small fun activity to write somethings on interviews, and software program jobs.

Understanding risk in investment

Dec. 22, 2019

Introduction

I like to write something related to risk, I just learned negatively related case study through boglehead.org, and then I found out that it is so interesting to learn how to hedge, and also diversification of S & P 500 Index -> 400 -> 300 -> 50 -> 1 also translates from investment to speculation. I like to talk about risk more carefully.

How to understand risk?

It is hard for me to learn about risk. Because I have to put 50% of my asset into stock trading accounts, I had hard time to put into those portfolio in May 2019.

I do understand that I have to hold high standard on my personal finance learning. The more I learn the more I can earn. I also like to add one more constraint, if the market goes up, I will earn money since my portfolio follows the market. I will not try to beat the market.

I have interest to learn more how to reduce stress as an investor. One idea is to read more books, and then articles, meet more people to serve the site like boglehead.org. I like to spend time to read well-written articles on boglehead.org, I found out that those articles are best ones so far.

Taking risk

The risk I take is that all my research and portfolio is based on worst scenario 2008 to 2009. More detail, the 2008 - 2009 recession S & P 500 index has 60% loss, two dips. But what if 2019 has a recession with 80% loss, two more dips, last more than three years.

I am 53 years old. How to manage risk from 53 to 57 years old? I never look into my age, my health and also challenge for people in 50s.

What is next?

I like to write topics like to take risk in my career, my weekend projects.

I need to understand how to evaluate the risk, how can I learn from my failures in 2019? I need to review what risks I take not just in equity market.

What if I work another 240 Leetcode algorithms?

Dec. 22, 2019

Introduction

It is my personal finance research. I have choices to learn more about web service, restful web service, VUE JavaScript, Python, or I can focus on Leetcode algorithm and solve 240 algorithms. How to evaluate the idea and allocate time to study and prepare for 2020?

Ideas to think about

Here are highlights to work on 240 algorithms.

1. It is learning process. I may find my own weakness in terms of problem solving, thinking process. There will be some surprises.
2. I will spend time to do hard work, solve a problem, write a discussion post; I will not have easy time to read a book, article, no worry about performance.
3. I will invest time three to six months first, expect that I will get return for those investment. Hours spent will be over 300 hours at least, each week 20 - 40 hours/ week.
4. I will master a few more algorithms. And also I can meet a lot of people through discussion posts, weekly contest, discussion post, mock interview using algorithm and data structures.
5. I may have to find some algorithms to ask review on stackexchange.com. I have to push myself to contribute to the community.
6. Even if I do not have a software programmer full-time job, the hobby to solve Leetcode brings great benefit in my life.
7. It can help me to prepare a manager job, since I already have a lot of hours training. I know the process, hard work, communication and rigorous part related to algebra, combinatorics, and analysis of problem solving.
8. It is fun to push myself to solve algorithm problem. It is a good habit to write code every day.

My niece has a winter break one month

Dec. 22, 2019

Introduction

It is tough to be an aunt. My sister called me and complained to me over one month ago, why I did not mail my cousin's Canada permanent resident card to him, he is working on computer science graduate admission test holding around the end of December. I was busy and I took the break to talk to my sister about my niece winter break in Toronto area, Canada.

An invitation

I learn that I have to send out an invitation to invite my niece visit the city of Vancouver, and also I need to purchase round trip airline ticket first since she does not have credit card yet.

I have so many projects to work on. Usually the Christmas and New year holiday is best time for me to catch up my personal finance research.

My complaint

I complained to my sister, my niece started her school in October. She only studied two months, now she has one month break. Next January to May she has five months to study. Only seven month two terms.

Learn to be an investor

Dec. 22, 2019

Introduction

I like to write a story how I become an equity investor starting from this May. I also shared the stories with my wechat group 1984 Shanghai Jiaotong university. Life is tough, and I have to learn personal finance, and understand what wall street does for economy, and I have to grow up as a rational investor, learn how to avoid take little risk or too much risk.

My story

I believe that it is best opportunity for me to learn if I choose to share my understanding with my wechat group.

I can understand the question from my friend, and also explain the idea to manage risk using bonds. I just take a few minutes to upload my wechat conversation, share here.

Date my money - move fund from US bank to Canada

Dec. 21, 2019

Introduction

It is so challenge to learn how to invest. As a person with research experience, I have to push myself to read and learn as much as I can, otherwise bear market comes, the best time to invest and accumulate the wealth, I will be scared and sell off instead. One thing is to put fund into Questrade.com, I have to date my money, and then do not let money sit in checking account earning zero interest, or CD earning 1.2 interest.

Date my money

I have to go out every day from Dec. 21 to January 2. I will work on my personal business, and work on other things as well.

I need to write a check to myself, and then deposit into Scotia bank, later I can deposit into Questrade.com.

Actionable Item

I just got the news, my rental property water heater does not work, after 20 years, I need to get a new one. I should keep those fund in US chase bank to pay my new water heater and installation.

Dec. 22, 2019 12:00 AM

I made a mistake, I should double check. The teller sold my US dollar to Canada dollar, and save it to my Canadian checking account. The rate is 1.2814.

I asked the teller to save the check into my US dollar account, after that, I will convert it to Canada dollar to a small place like Can-China Financial services Ltd. The rate today I asked is 1.306.

The difference is $3700 * ( 1.306 - 1.2814) = $91.02 Canadian dollars.

I will walk in Scotia bank next Monday afternoon, and ask if I can get refund and then save it to my US dollar account. I will have Monday afternoon off until January 2, 2020. The factory will be closed for holiday break.

It takes hard work to build wealth. I have to pay attention to small detail.

Dec. 22, 2019 9:47 am
The check is saved to US saving account.

What is on the receipt? why CAD equivalent is listed on receipt?

Case study: Amazon Vancouver AWS woman event

Dec. 21, 2019

Introduction

I attended the event on Dec. 17, 2019 in the city of Vancouver. I am 53 years old, and most of people showing up 80% are younger than me. Some of them just started their career. I like to do a short case study on this event.

Case study

One of question is to ask how to start software engineer career after working 10 years, career transition to computer science. Another question is about performance review.

I understood that it is so important for me to acquire some skills, which I am weak in those areas. Project management skills, communication skills, cognitive abilities.

For me, since I am working on personal finance research starting from Nov. 2018. First question coming to my mind is to figure out how an Amazon manager who works there over 20  years manage the wealth. Does she manage by herself or hire a portfolio manager? That can be huge amount of wealth, stock double double and double, I may miss a lot of double over there. ROSS stock 40 times more after 20 years.

Also I need to find a role model who chose to leave USA, came back to Canada, how does she manage the successful career.

There is no surprise. I had chance to meet people and ask questions.

I need to get organized. I need to study hard, learn a little and benefit whole life.

Two managers I have chance to write down names. Kim Thunen, another one is Salimah Addetia.

Video:Bogleheads® investment philosophy

It was such great teaching through those videos. I learned first time how to make hedge using two companies, bath suits inc and umbrella inc, which is related to how to manage risk topic.

Case study: CSS position:absolute

Dec. 20, 2019

Introduction

It is the bug I created since I did not notice that the special case at work. Recently I added some margin in the website, and then if there is seven items, then last item will not displayed properly. I did not notice the issue until some one in the office told me so.

Case study

I quickly fixed the issue since I like the child div can have bigger width than parent div. So I learned from stackoverflow.com one question, the answer is to use CSS position:absolute.

My question to myself is to work on CSS by reading more often the tutorial. I should try to push myself to improve my CSS by actively reading the website.

The way I learn about CSS is not proactive. I should prepare myself to be expert one day in CSS.

Here is the website.

grid_10 class is defined the width of parent div - 820, total width 1008 for 12 grid, 82px for each grid.

Now the child div has more than 840 px.

Actionable items

I like to figure out how to master CSS, so I can have time to work on restful webservice, and framework for the front end.

40 business books everyone must read to be successful

Dec. 20, 2019

Introduction

I like to find a few business books to read from those 40 business books.

40 business books

Here is the article.

Restful Web Services

I plan to read the book in short future. I need to push myself to read a book, at least I can understand the ideas. It is hard for me to practice restful web services, but I should be able to find the book and start to read it.

I got the advice from the article here.

Follow up

First two hours study on January 9, 2020

Zalando: How to pass the interview

Here is the article.

Excerpt:

For the API design, you need a basic understanding of REST and HTTP. It is not expected you know fancy media types or the intricacies of HTTP proxies but you need to know how to structure an API and its data using HTTP and JSON. You should have a look at the Richardson’s maturity model (till level 2) and perhaps have a quick look at his book, RESTful Web Services. (Richardson’s newer book, RESTful Web APIs, deals with REST level 3, i.e. hypermedia controls, which is more advanced and out of scope for the interview)

Actionable Items

I just could not believe that I should read restful web services book much early, I work full time from 2010 to 2019. I did not do book keeping every year, I did not read web services book every year from 2010 to 2019. 

This life style is ridiculous, I just could not believe that I did make choice.

Case study: hundreds of hours with relatives on wechat

Dec. 19, 2019

Introduction

It is my personal finance research. In order for me to find time to learn personal finance, I have to learn how to avoid time-consuming activities. One thing I like to work on is to case study the time I spent from 2010 to 2019 on wechat with my relatives in China.

Case study

Once a while, I will always think about what I should do as a sponsor. I will think about my nephew and how I should help and work on his plan in Canada in 2019. After a few months of study, I learn that I have problems to make decisions. I need to find the good book to teach on this, I came cross the book through one of videos.

It take some time for me to learn that I waste my time to worry about things. I should be responsible for myself. As a single person, it is most important lesson for me to learn. How to manage my time? Work on my thoughts, focus on my own business.

To be a learner, I have to spend time, I need to track down what I read, and read a book as well.

3 tips to save time

I should think about mutual benefits. If there is no plan, then there is no need to talk.
Do not argue anything with siblings. I did my best to serve my mom as a daughter before my mom passed away in 2017. Now it is time for me to build my own life, work on my own life.

Indeed, the S&P 500 index is the most popular measure used by financial media and professionals, while the mainstream media and the general public might be more familiar with the Dow Jones Industrial Average.

It is important for me to learn how to communicate. I think that it is more important for me now, since I can write better code. How to work on my project management skills?

One idea

I learned from pluralsight.com writing code for humans, separate CSS from html and JavaScript. I shared the idea at work with my coworker, I will make sure that all style sheets will be in .css file, so she can try various ideas after our initial design together, therefore we will have much better presentation in web page. I also can free some time, I like to try a few frameworks, so I can write a new website for the company.

Work together and build a team

I like to try restful API, MVC, and web service, and VUE.js framework.

My coworker likes the design, she works on marketing. She was very happy, I told her that it is very important skills to learn how to design using CSS. It will take some time to be an expert, every day 30 minutes reading, after one year she will be an expert, and it is very good for her career. Specially it is easy for her, since hear reading skill is above 8.0 in IELTS test.

Last few months, we worked together for a few projects, I always showed her how I make changes, find examples, read CSS tutorial page.

Because we work together, I also learn so many things. It is not easy to come out very good design, we have to go through the learning process, try a few ideas.

Talk about insomnia

My coworker asked me what happened yesterday as a sick day. I told her that I had insomnia. I explained to her that it is better to take a day off. I could not fall asleep until 4 AM.

It is not healthy to stay in the office whole day with only less than 4 hours sleep.

Introduction

It is time for me to write a small research report called what if I am Capilano suspension bridge park product manager. I like to explore all kinds of ideas to bring into more business and play an important role to share Canada culture, forest and nature fascination.

One more sick day in 2019

Dec. 17, 2019

Introduction

It takes some wisdom to understand what is a sick day. How to determine if I should take a sick day leave. I like to take a sick day since I has insomnia this morning. It is better to call one more sick day instead of last sick day.

How to recover from a sick day

I like to go out swimming. I just got up around 11:00 am, and also took a walk around the community.

How to cope with insomnia?

Dec. 17, 2019

Introduction

It is important for me to slow down to allow myself recover from insomnia. Last night I could not fall asleep until 4:00 am. So I decided to take a sick day, I like to learn from this insomnia incident, and understand how to work with my physical concern in my 50s.

Case study

I like to put together 10 activities I did last night. I like to figure out how to prevent insomnia and how to cope with it.

I made the phone call around 8:00 AM, and continued to sleep until 11:00 am.

A friend's advice

Dec. 17, 2019

Introduction

It is something I like to learn. Since I like to build wealth and grow rich, I like to learn from successful friends I have. But they do give out advice to suggest me avoid taking any risk.

Case study

I went to suspension bridge park with my friend who is a principle engineer in Sillicon Valley last Friday. We did discuss my career choice at dinner table in Chinese restaurant, she does not believe that everything will be great if I compete a job in Facebook or startup. She suggested me to think about working as a real estate agent in weekend.

Questions asked:
1. Do you have big project experience?
2. Do you know the boot camp first three months every week you have to complete a project?
3. Can you compete with people in 20s?

I just could not believe that I like to work on coding every day. I also like to be an interviewer on interviewing.io as well. My interest is changing all the time, it used to be hackerrank contest, and then code review stackexchange.com, and then leetcode weekly contest. I just learn how to master some algorithms in my life first time, and I like to use this experience to help me build wealth and grow rich. I am working on personal finance, investment.

I like to work on a few more case study, and see how I can learn how to make good decisions.

Being frugal 

One of ideas is to be frugal. I like to put wealth to work. I already put my saving into S  & P 500 index, and this is the first time I learn that the return is 25% from May to December 2019.

Actionable Items

Confidence is the biggest item I should frequently check. How to build confidence, and learn from my own failure. I should look into this area.

I should not worry about too much about friend's advice. She did fantastic job to connect me with other people and we met in San Francisco before the onsite this August. It is so amazing to get together, two MBA and product managers of Google, Linkedin manager, Apple manager one principle engineer showed up in our dinner party.

Suspension bridge park second visit

Dec. 16, 2019

Introduction

I thought about my weakness in personality. How come I do not have that personality to accumulate million dollars talent through 24 years in north America. I still work on learning how to enjoy life being frugal.

Second visit

I stepped out onsite interview from dialpad office building on melville street. There was a free shuttle bus to suspension bridge park in North Vancouver. I decided to take the bus and visited the park again using my annual pass. I needed to take some time to enjoy the outdoor.

Take selfie 

It is tough to be a person over 50 years old. I learn to work with myself better. One of ideas is to push myself to read more books, visit more places in local area.

I got my Google hat from Oct GHC event in the city of Seattle new lake union office. I just walked outside the building, finished 4th onsite interview in 2019, and then took bus and it only took less than 30 minutes to get the park.

It is so comfortable to stay outdoor and share this great picture with you at the end of 2019.

Second visit I also know the length of bridge, height from the valley bottom, how many weight it can hold.

What if I am the product manager, how much it costs to hang those lighting balls?

I like the rain of Vancouver. I know that there are snow on top of mountain. I should go up the mountain and go skiing.

System Design - Sharding | Data Partitioning

Here is the link.


Sharding or Data Partitioning: - Sharding is a technique to break up a big database into many smaller parts - Horizontal scaling means adding more machines, which is cheaper & more feasible - Vertical scaling means improving servers - Partitioning Methods: - Horizontal partitioning: - In this we put different rows into different table(db), i.e. rows can be based on location with zip codes, this is also range based sharding - Problem is if range is not choosen carefully, it'll lead to unbalanced servers. - Vertical Partitioning: - In this we divide data to store tables related to a specfic feature to their own servers.i.e. In Instagram, we can have 1 for user profile, 1 for photos, 1 for friend list. - Problem is in case of additional growth, its necessary to further partition a feature specific DB across servers. - Directory based Partitioning: - In this, create a lookup service which knows your current partitioning scheme & get it from DB access code. - To find out a data entry, we query directory server that holds the mapping between each tuple key to its DB server. - This is good to perform tasks like adding servers to the DB pool or change our partitioning scheme without impacting application. - Partitioning Criteria: - Hash-based partitioning: - In this we apply a hash function to some key attribute of the entity we're storing, that gives partition number. - Make sure to ensure uniform allocation of data among servers - Problem is it effectively fixes total number of DB servers, since adding a new server means changing the hash function, which would require redistribution of data & downtime, the workaround is Consistent Hashing. - List Partitioning: - In this each partition (DB server) is assigned a list of values, i.e. APAC, EMEA, US region has respective partition. - Round-robin Partitioning: - One by one assign which ensure uniform data distribution - Composite partitioning: - Combining any of above partitioning schemas to devise a new scheme. i.e First list partitioning with hash partitioning in each. - Common problems with Sharding: - Joins & Denormalisation: - Performing joins on a database which is running on one server is straightforward, but if DB is partitioned & spread across multiple machines, it's not feasible to perform joins that span database shards. - These joins won't be performance efficient. - Workaround is to denormalise the DB so that queries that required joins can be performed on single table. - Referential integrity: - Trying to enforce data integrity constraint suh as foreign keys in a sharded DB can be extremely difficult. Most of RDMS do not support this. - Rebalancing: - When data distribution is not uniform. - When there is lot of load on a particular Shard. In this video, we're going to reveal Sharding used in System Design: - What is Sharding/ Data Partitioning - Sharding Methods - Sharding Criteria - Sharding Challenges

30 Signs Someone Will Never Become Rich

Here is the article.

30. Terrrified of failure
29. You only work 40 hours per week
28. Public speaking makes  you nervous
27. You avoid talking on the phone
26. You refuse to move
25. Working by the hour
24. A jack of all trades, but a master of none
23. All talk, no action
22. Never reading
21. Being chronically late
20. Waiting for a miracle
19. Not having financial goals
18. Never trying new things
17. Hating your job
16. Seeking approval from others
15. Taking care of others instead of yourself
14. Starting projects and never finishing them
13. Focusing too much on saving
12. You don't have investments
11. Taking advice from other poor people
10. Not believing in yourself
9. Lacking discipline
8. Commuting over an hour to work
7. Buying things you can't afford
6. Pursuing someone else's dreams instead of your own
5. Content with a paycheck
4. Imagining that getting rich is impossible
3. Accepting wrong kinds of feedback
2. Unable to adapt
1. A lack of motivation

My favorite learning is the following:

25 Working by the hour

The only way people truly get rich is to be paid by results, rather than time. Every single human being has the same 24 hours in a day. The rich ones just figure out a way to make money in a short amount of time. They don’t worry about getting paid by the hour. The end result matters much more.

20 Wait for a miracle

Statistically speaking, poor people tend to be religious, and rich people are more likely to be agnostic or atheist.

Case study: Design youtube or netflix

Dec. 15, 2019

Introduction

I like to spend next 30 minutes to read the article called Designing Youtube or Netflix before 12:00 AM. Now it is 8:58 PM.

Author who studies millionaires: How to get rich and then stay rich

Here is the article.

Being rich, or becoming financially independent, boils down to a two-step process:

1. Accumulate wealth
2. Keep the wealth you've accumulated

Getting rich

Daily growth

Rich relationship

Dream-setting

Persistence

Developing a niche

Creating multiple streams of income - create a hedge against failure and poverty. When one stream suffers, the others come to rescue. 

Being patient

Taking calculated risks

Being optimistic and enthusiastic

Controlling your thoughts, emotions and words

community

Staying open-minded

Giving first and getting later

Finishing what you start

Staying healthy

Taking responsibility

Staying rich

put your wealth to work - invest it wisely in stocks, bonds, real estate and other business opportunities. this helps multiply your wealth. 

Watch what you spend

Avoid spontaneous or emotional purchases

Live below your means

Actionable Items

I think that it is important for me to enjoy being frugal. I do not need to take a vacation to fly somewhere. I should stay in the city of Vancouver, and enjoy simple things in life. 

Also it is important for me to learn how to put wealth to work. I have to learn how to invest, and work on my finance literacy. 

One more thing is to count how I spend time on daily activities. I should choose healthy life style. 

Case study: Instagram system design

Dec. 15, 2019

Introduction

It is well-written article how to design instgram. There are 11 pages in grokking system design. I like to take some notes for each page, I just finished the reading of those pages.

Case study

I do believe that best learning is to read the content. I should learn how to read better, and also take some notes if I come cross some concepts, good analysis with explanation.

Simple version of instgram, where a user can share photos and can also follow other uses. The 'News Feed' for each user will consist of top photos from all the people the user follows.

Requirements/ Goals

Functional requirements
1. users should be able to upload/ download/ view photos
2. user can perform searches based on photo/ video titles
3. user can follow other users
4. The system should be able to generate and display a user's News Feed consisting of top photos from all the people the user follows.

Non-functional requirements

High level system design

block storage servers to store photos and also some database servers to store metadata information about the photos.

Database schema

data about users, their uploaded photos, and people they follow.
tables:
Photo
User
UserFollow

RDBMS like MySQL, problems when we need to scale them

A distributed file storage like HDFS or S3

Key-value store

wide-column datastore like Cassandra
relationships - users and photos, who owns which photo
a list of people a user follows

UserPhoto - key is UserID, value will be a list of photoIDs
UserFollow table -

Cassandra or key-value stores in general, always maintain a certain number of replicas to offer reliability. Also, deletes don't get applied instantly, data is retained for certain days (to support undeleting)

I will google Cassandra and have a short review later on.

Component design

web servers have a connection limit, for example 500 connections

To handle this bottleneck we can split reads and writes into separate services. Dedicated servers for reads and different servers for writes to ensure that uploads don't hog the system.

Reliability and redundancy 

multiple copies of each file, multiple replicas of services running in the system.

single point of failure - redundancy removes the possible problem.

Data sharding 

one DB shard is 4TB, and then 178 shards for 712 TB.

append shard number with each PhotoID - 

How to push myself to learn more from onsite interview?

Dec. 15, 2019

Introduction

It is time for me to prepare a checklist, what I can learn more from the onsite interview. I like to move my focus away from myself, and then try to push myself to work on improvement during onsite. As I learn from a talk yesterday, system design interview is like giving out a tech talk, I have to learn how to cover more areas instead of pushing by the interviewer.

Think like a senior engineer

I should always ask clarifying questions. Ask more questions to show interesting, and also explore the algorithm or topic more carefully.

As I learn from the book talking about decision making, I should at least find more than one solution, and two solutions have less risk, three solutions should be perfect; more than three is waste of time. Three solutions will reduce the risk of mistakes, and then choose one of solutions to get into detail.
