• The hammer is falling.
• Following the surge of short videos, investment advisory services are reportedly entering a fast lane.
• In late September, after a period of intense activity in the A-share market, Douyin (TikTok) recommendations for stocks garnered attention from various parties.
• Numerous financial commentators have risen to prominence on Douyin, indirectly causing some volatility in capital markets.
• Behind these rapidly rising financial commentators lies a significant force: third-party investment advisory service companies.
• It’s understood that many third-party advisory firms operate multiple accounts on short video platforms, using content distribution (投流) to attract users to watch investment teaching videos and boost enthusiasm for purchasing corresponding products.
• There are even rumors that one third-party advisory firm achieved revenue of 10 billion yuan in October alone, exceeding its first-half earnings.
• However, “good times” are facing more uncertainties.
• Since November, multiple departments have issued notices requiring securities service institutions to strengthen the compliance management of self-media accounts.
• On November 15th, Futu Securities (300033.SZ) announced that a subsidiary was penalized by the China Securities Regulatory Commission for engaging in suggestive stock recommendations through livestreaming.
• This may be signaling a stricter regulatory environment.
• The expansion of third-party investment advisory service firms like Fangyuan Intelligence Investment (9636.HK) is likely to face greater pressure.

Close Monitoring by Regulators

The rise of short video platforms like Douyin (TikTok) has amplified emotional voices and indirectly impacted trading behavior.

CentOS Stream is the upstream open-source development platform prior to Red Hat’s Linux distribution.

I first noticed the open-source operating system lifecycle redhat and centos life cycle had ended, and I was wondering what was going on. Besides security issues, dnf wasn’t working, and I recently encountered failures when installing tools – checking the repository sources revealed that CentOS 8 Stream had reached its end of life.

CentOS Stream Introduction

Positioning and Roles

CentOS Stream sits between Fedora Linux (upstream development) and RHEL (Red Hat Enterprise Linux, downstream development), acting as a bridge.

Browsing through the historical commit records, the site has undergone numerous theme switches. Each theme switch involved some custom modifications, and this is where I’m documenting the approach to customizing themes. My Github repository briefly maintained the even theme, but due to my obsessive-compulsive tendencies, I resisted upgrading the hugo compiler to the latest version, which resulted in incompatibility with the even theme, so I switched back to the stack theme.

• Recently, the popular “Da Bing” (Big Ice) on Douyin (TikTok) has been frequently seen with short video accounts extracted from her live streams. A listener who joined a live call asked: “Da Bing, I want to sell my house in Xi’an and return home to settle down.” Da Bing responded: “At your age, you’re in your early thirties; you can’t settle down. Your parents are on the path of aging, your children haven’t started a family or established themselves, and if you return home, you’ll still need to deal with the poren.” Let’s set aside whether the viewpoint is right or wrong, what does the term “poren” mean?

Township Brahmins: The “Big Shots” of Small Places

In many small county towns, people often talk about so-called “township brahmins”—the existence of these individuals seems to be a symbol of local society. They are not necessarily genuine religious figures and do not possess “high-level” titles; rather, they are seemingly ordinary but nonetheless influential people. They represent “power, status, and influence” within that county town, symbolizing a particular class or stratum in that area.

In the history of C++ development projects, we utilized a custom protocol for communication, which employed a two-dimensional array pattern. When processing large volumes of data, the protocol required iterating through the arrays and performing serialization operations to generate logs. Due to its low efficiency, this resulted in noticeable lag or stuttering within the system under heavy load, as reported by the business departments.

Problem Identification

When troubleshooting the issue, we first performed a performance analysis of the system and discovered that CPU utilization increased significantly when processing large amounts of data, and system response times became longer. By analyzing the system logs, we identified numerous serialization operations, which were inefficient when handling two-dimensional arrays, leading to a decline in system performance.

In C++, lambda expressions are a convenient way to create anonymous functions that can capture external variables and use them within their bodies. This makes lambdas a flexible programming tool. However, the lifetime of parameters in a lambda expression is an aspect that requires careful attention, especially when capturing and passing parameters.

1. Lambda Expression Parameter Lifetime

The lifetime of parameters in a lambda expression is typically the same as that of other C++ functions. Parameters exist while the function is being called, and their lifetime ends when the function call terminates. However, due to the possibility of lambdas capturing external variables, the parameter’s lifetime is also affected by how it’s captured.

Picking up where we left off, I discovered that GitHub had an update, which was a little exciting. The customer service team said the issue with the driver not loading properly was resolved. However, after going through all of this – reinstalling and uninstalling – it still wasn’t working correctly.

Background

Continuing to contact customer service to inquire about a resolution, I was informed that an engineer could provide remote assistance. However, the engineer’s working hours coincided exactly with my own, leaving me with no option but to abandon the effort. Reviewing the documentation from the previous troubleshooting issue, I decided to attempt a manual driver installation.

If you completely don’t understand these things, contacting official customer service first will also avoid wasting several hours.

Recently, the C drive on my desktop computer, which I use for development, had run out of space. I specially took out a 256GB semi-retired solid state hard drive and used it as the C drive. Unfortunately, I kept messing around with it. Since moving to Shanghai, I’ve been busy with various things, and last week I finally took some time to reinstall the system.
