Firstly, it is the scale of business. Due to geographical and cultural reasons, most domestic companies encounter some difficulties in going global, mainly in the domestic market, which is much smaller than the European and American markets. The same is true for public clouds, where the revenue and market value of AWS, Azure, and Google Cloud in the European and American markets are higher than those of Alibaba, Tencent, and Huawei Cloud in China. Since the development cost can basically be shared, the average salary of developers in American companies is higher than that in China, which can hire relatively more excellent talents; it can also generate more profits to support relatively long-term research, such as OpenAI, Deepmind, and Microsoft Research. Breakthrough innovations like ChatGPT are hard to come from product departments with intense development rhythms, they usually come from research departments without much short-term commercial monetization pressure.

Computer Network & Protocol Laboratory

Huawei’s Computer Network & Protocol Laboratory is a subsidiary of the Distributed and Parallel Software Laboratory of the Central Software Institute of the 2012 Laboratory, with locations in Beijing, Shanghai, Hangzhou, Shenzhen, and Tel Aviv, Israel.

Vision: Rooted in laying the foundation stone, innovation leads the future of distributed communication

Positioning: Huawei’s software engine in the field of computer network and protocol technology, covering theoretical breakthroughs, technological inventions, technological innovations, and quality delivery. Standing at the forefront of this technical field, we research and break through world-class technical problems in computing native networks and wide-area network deterministic communication, build an industry-leading full stack of distributed communication, and work with ICT, terminal, cloud, intelligent car and other main product teams to build differentiated communication competitiveness, gradually grow the industrial ecosystem, and help business success.

Team: A high-level innovation team composed of top industry-leading experts, genius youngsters, PhDs, and engineers mixed special forces, overseas legions. The technical research results are significant. Since 2018, 5 papers have been accepted by SIGCOMM, the top global network communication conference; and key technologies have been selected into Huawei’s top 10 inventions for three consecutive sessions.

How many trips per year?

Since 2012, up to now, I have been to … cities, and traveled … times (going from city A to city B counts as one trip; if I go back to city A again, that counts as two).

Which cities have I stayed in the longest?

Note: If I enter on January 1 and leave on January 2, it is counted as 2 days, so there is double counting and the total number of days exceeds the number of calendar days.

If we consider all cities except Beijing and Hefei as travel (including business trips), then the total number of travel days accounts for …, in total … days.

This article summarizes the technical architecture of USTC iCourse.club. Founded in 2015, iCourse is a Flask-based website aiming at rating courses in USTC (University of Science and Technology of China). Although it is only a small website from a technical point of view, it offers a glimpse of the architecture of a typical web service.

USTC LUG GitLab will soon stop serving non-campus users. Although I have a campus email, to prevent sudden disconnection one day, I have backed up all my repositories locally and hung the public repositories on GitHub. As the first user of LUG GitLab, I have a total of 209 repositories, 123 of which are personal repositories. LUG GitLab was established on March 14, 2013 (Pi Day) and has been running for 9 years, even slightly earlier than Telegram. GitLab and VPN are the longest-running (9 years) network services I have established, serving thousands of users. I have long left the management and operation team, but I still have a lot of feelings for these services.

These public repositories are mainly the course assignments I did at USTC, various undergraduate projects, and network services I did at LUG. Most of the projects I did during my PhD at MSRA have not been open-sourced. I only released the source code of SocksDirect and the LaTeX source code of several papers, some of which have been anonymized and do not retain internal commit information. The source code after work is even less likely to be made public at will. The already open-sourced MindSpore AKG project also anonymized the internal commit information when it was open-sourced (internal contributors after open-sourcing are directly developing on the public repo, but I have left the AKG project after open-sourcing).

Therefore, from the contributions on GitHub, you can see that the most contributions were in 2016, with 2000+ contributions; last year and the year before, there were only a pitiful number of contributions; there were 1000+ contributions from 2013-2015; only a few hundred from 2017-2019, one reason is that the project was not open-sourced, and the other is that I personally was somewhat detached from the front line of coding, pondering new research ideas all day, becoming a PPT engineer, and not spending much time on actually coding to implement ideas, which is also why I published fewer papers in the later stages of my PhD.

“Where did that gazelle go?” Mom suddenly asked me.

The gazelle Mom was talking about was a craft made of black hardwood. It was a gift from my dad when he returned from Africa. It had always been on the corner of my desk. At this moment, my heart started to pound, because I had given it to my good friend Wanfang yesterday.

As one of the founders of the USTC Course Evaluation Community, I am willing to promote the 2021 effort of several collaborators on my personal homepage: PI Review (https://pi-review.com/).

It has been 7 years since the establishment of the Course Evaluation Community in 2015. The community now has over 16,000 reviews and has a significant influence among USTC students. Many students refer to the reviews on the community when selecting courses. Anyone who has pursued a PhD or Master’s degree would likely agree that a mentor is crucial to a student’s life and future during these years. Although there are already many websites for evaluating mentors, such as Mentor Recommendation, Rate My Supervisor, and Research Control, they all have many issues. Here is a more detailed evaluation. The founders of PI Review discovered that there was no satisfactory website, so they established PI Review in 2021 and have added many new features this year.

PI Review operates on an anonymous basis. You only need to verify with your school email to post reviews, but the email verification is solely to prevent spam. Email addresses will never be made public, and we will not send spam emails. All posted reviews are anonymous. We welcome everyone to share their own or their friends’ mentors. If you think a mentor is good, you can help yourself by bringing collaborators on board. If you think a mentor is not good, you can help junior students avoid pitfalls.

PI Review currently suggests evaluating mentors across 5 dimensions, including Advisor Style & Mentorship (hands-on or hands-off, etc.), Expectations (publishing papers, work hours, etc.), Funding & Support (salary, internships, etc.), Research, and Lab Culture. Of course, this is just a reference, and you can evaluate mentors according to your own dimensions.

During my own PhD period, both of my Microsoft co-supervised mentors were very good to me, providing a lot of guidance and help. I have also written reviews on PI Review. If you are interested, you can look them up. The search function for mentors should be quite useful.

During the dance performance, the first half of “Flowers and Moon in Pairs” got stuck for the first time, restarted, and then got stuck twice again… becoming the program that brought the most joy to the audience :)
