Second Letter to Readers & Li Ding Nao Nao & Answer to Reader’s Letter

The letter I wrote last time to the first readers is here , newcomers can take a look. The response to the last letter was good, so I plan to continue writing.

Before replying to the letters from readers, let me advertise my new newsletter:

Li Ding babbles

This “Li Ding Nao Nao” email subscription is relatively high-frequency (every 1-2 days) without a fixed theme and no nutrition. Chatter, as the name suggests, is idle chatter. In contrast, the emails you read now from the “Li Ding Chat Room” are relatively infrequent. They send out a program-related issue every two weeks, and occasionally send a letter to the audience. That’s about it.

The following are the blogs I wrote recently for ” Li Ding Nao Nao “, if you are interested, you can subscribe! https://liding.substack.com/subscribe

I also said in a Tweet :

The probability of each episode being recommended by the platform algorithm on station b and youtube is very different.

??? In the last episode, the program that the professor left to go to Tencent North America has exploded on the B station.

?? This issue of Singapore professors sharing the life and work in Singapore is more popular on Youtube than ever before.

Don’t know what’s going on with the algorithm behind it? Of course, part of the reason must be the audience’s viewing and like preferences.

Do you like this issue of Tencent North America or this issue of Singapore Immigration?

The Phd of Graphics is looking for a job related to finance. If the job content is far from the work during the Phd period, will it have any impact (with those who graduated from majors)

The difference is not very big.

If it is a product group instead of a research group, is it necessary for an enterprise to recruit phd?

PhDs are not required for most positions, and not all so-called research positions require a PhD.

Seeing that you mentioned that students or teachers in school will have some narrow perceptions, can you give a few examples? thanks.

There are many narrow perceptions. Let me list a few that I have experienced myself, or that my friends have experienced. Some may sound bizarre, but trust me, it all happened to me or my friends.

Below they refer to “some doctoral students or professors”

  1. They think that if you don’t work hard to find a faculty after graduating from a Ph.D., it is not a proper job.
  2. They think that going to Wall Street or to Fintech companies after graduation (but not to FAANG Research) is also considered a bad job, or to get money.
  3. They think that by giving up some opportunities (geography, salary, career) in order to support your family, you’re just forgetting where you started

I generally attribute this to the PUA in PhD, so don’t be swayed by these misconceptions.

Hello, I see that you have done some 3D printing and computational manufacturing related work during your phd period. Do you still pay attention to this field? How is the academic or industrial development in this field now or in the future?

I don’t care much about this area anymore. Originally, I thought that the turning point of 3D printing would be the popularity of traditional paper printers. But it seems that many people now have no paper printers at home because they are all operated on the cloud. So I’m a little lost as to what the tipping point for 3D printing will be. Some possible signals include improved stability (no need to repair the printer every day), improved 3D modeling accuracy (I scan a broken plastic part and it will be printed immediately), sufficient data sources (such as various Large manufacturers open up some models of their own hardware), and the printing accuracy is improved (the models shared by others on the Internet can be used by me when I type them out).

But since I don’t follow closely, it may not be very accurate.


Well, that’s it for this letter to readers. If you have any questions, please reply to this email, or twitter @me/DM me. If you have any questions, please contact me.
