Musk Denies Tesla Abandoning Low-Cost Car Plan#
[Musk denies Tesla has abandoned the low-cost car plan] Caixin, April 5 - After Musk denied that Tesla had canceled its low-cost car plan, the company's stock price recovered some losses. The stock fell 6.2% on Friday after Reuters reported that Tesla had abandoned the low-cost car plan. Musk posted on social media platform X, stating, "Reuters is lying." Musk first proposed a $25,000 model at an event in September 2020, saying that a series of innovations at Tesla gave him confidence that the company could produce such an electric vehicle within about three years. More than three years later, Tesla's product lineup still lacks lower-priced models, proving that the brand's cars are relatively expensive.

The Data from "Idiot Tieba" Turns Out to Be the Strongest Chinese Corpus#
The Chinese Academy of Sciences, Peking University, University of Science and Technology of China, University of Waterloo, 01.ai, and other 10 institutions have jointly launched a high-quality instruction fine-tuning dataset specifically for Chinese - COIG-CQIA.
In the field of large models, English has always been the most important training data language, but due to structural and cultural differences between Chinese and English, directly translating English datasets into Chinese is not ideal. Therefore, to fill the gap of high-quality Chinese datasets, researchers developed the COIG-CQIA dataset.
COIG-CQIA has almost captured high-quality datasets from Chinese internet forums, websites, Baidu Tieba, Q&A communities, etc. Using COIG-CQIA for instruction fine-tuning on Yi-6B and Yi-34B, and then evaluating the performance of large models trained on various datasets with GPT4 on BELLE-EVAL.
An interesting scene emerged, where the data quality from "Idiot Tieba" significantly exceeded that of well-known knowledge communities like Zhihu, Douban, and Shifei, truly reflecting the wisdom of seeming foolishness~

Paper address: COIG-CQIA: Quality is All You Need for Chinese Instruction Fine-tuning

In fact, this data has already undergone many rounds of manual evaluation, so the quality is certainly high, especially in places like Idiot Tieba, which often contain puns, polysemous words, causal reversals, and homophones, many of which are designed with logical traps that even pose challenges to humans.
China's Fertility Rate Ranks Second to Last Among Major Global Economies, Cost of Raising a Child to 18 is Equivalent to 6.9 Times Per Capita GDP#
China's total fertility rate has dropped from around 6 before the 1970s to about 2 in 1990, and further down to around 1.5 after 2010, with 1.05 in 2022 and only about 1.0 in 2023, ranking second to last among major global economies (only slightly higher than South Korea).
High direct costs such as housing, education, and healthcare are the three major factors suppressing fertility behavior. The "four-two-one" family structure has a heavy burden for elderly care, squeezing childbirth, while the high female labor participation rate but insufficient employment rights protection leads to high opportunity costs. According to the "China Fertility Cost Report" released by Yuwa Population, the average cost of raising a child aged 0-17 in the 14 surveyed countries is 485,000 yuan; the average cost from birth to college graduation is 627,000 yuan.
If we compare the cost of raising a child to just 18 years old relative to per capita GDP internationally, Australia is 2.08 times, France is 2.24 times, Sweden is 2.91 times, Germany is 3.64 times, the United States is 4.11 times, Japan is 4.26 times, and China is 6.9 times, which is nearly the highest in the world.

New iPad May Be Released in the Second Week of May, Prices May Rise#
Mark Gurman reports that Apple is preparing to launch new iPad Pro and iPad Air series in the week of May 6.
The upcoming products include 11-inch and 13-inch OLED iPad Pro models, a larger 12.9-inch iPad Air, and updated Magic Keyboard and Apple Pencil, while iPad prices are expected to rise.
Both iPad Pro models will be equipped with M3 chips, while it is still unknown which processor iPad Air will use.
The code in the beta version of iPadOS reveals that the new Apple Pencil will feature gesture squeeze functionality, and the new Magic Keyboard for iPad Pro will have an aluminum base and a larger touchpad, making the tablet more like a laptop overall.
Gurman also mentioned that the basic model iPad and iPad Mini will be launched later this year, although the iPad Mini is expected to have minor improvements, mainly focusing on processor upgrades.

Just wait a bit... If it's too expensive or the upgrades are minor, consider switching to Android.
Shanghai Pilots Beverage Nutrition Grading#
Recently, Shanghai implemented the country's first beverage "nutrition choice" grading label. Based on the content of four components in beverages - "non-dairy sugars," "saturated fats," "trans fats," and "non-sugar sweeteners," the grading is assessed from high to low, labeled A, B, C, and D, with decreasing recommendation levels.
It is reported that before the pilot began, Shanghai's disease control department conducted nutritional analysis on some milk teas in the market, and the results were concerning. Just in terms of sugar content, over 93% of milk teas claiming "no added sugar" could be rated B or higher; nearly half of the milk teas claiming "one-third sugar" could be rated C or higher.

Who is Jia Tan, the Author of the xz Backdoor?#
One of the major recent events in the internet industry is the backdoor in the xz software.
xz is a compression software widely used in Linux systems, such as the system manager systemD, which uses it to compress logs. It is one of the basic components of Linux, found on almost every server.
At the end of March this year, someone discovered that the new version was a bit strange, causing the SSH startup time to slow down by 500 milliseconds. Further investigation revealed that there was a backdoor inside.
This shocked the industry because the new version was about to be included in major Linux distributions (like Debian and Fedora), just a few days away. By then, servers with backdoors would have catastrophic consequences.
Moreover, the entire incident was meticulously planned, spanning several years, with each step flawless, demonstrating a level of thoughtfulness, patience, and capability that is frightening.

Reviewing Feishu's Seven Years: The Least Douyin Product That Gained the Most Time#
Web Summary#
This article discusses how Chinese enterprise service products succeed, using Feishu as an example, exploring its seven-year development history, product features, market performance, and its connection with ByteDance. Feishu, as an all-in-one collaborative office tool, aims to enhance enterprise efficiency. Although it is still losing money, it shows commercial potential.
Key Points#
- Feishu, as an enterprise service product, aims to enhance enterprise efficiency and has all-in-one collaborative office functions.
- Feishu performs excellently in the Chinese enterprise service market, with software subscription revenue exceeding $200 million in 2023, but it is still losing money.
- The Feishu team once reached 8,000 people, now over 5,000, with each person bringing in about 280,000 yuan in subscription revenue annually.
- The value of Feishu lies in its commercial potential and its enhancement of internal efficiency at ByteDance.
- Feishu's seven-year development journey is a unique attempt by ByteDance, with its detours, lessons, and changes reflecting the boundaries of ByteDance's methodology.
Original Excerpt#
Outside of the implementation deployment team, Feishu also established a customer success department to help clients truly utilize Feishu while uncovering more needs to ensure renewals and upsells. This department currently has about 100 people.
Feishu has also made a series of adjustments to the product.
At the end of 2022, former Alibaba Cloud Disk head Qi Junyuan joined Feishu as product vice president. He previously founded the project management software Teambition, which was acquired by Alibaba in 2019.
Qi Junyuan led the development of Feishu version 7.0, which underwent a major change from "people looking for applications" to "applications finding people."
This is a solution for the bloated all-in-one. Previously, Feishu was an "App Store," where users had to search or click through submenus multiple times to find different functions; Feishu 7.0 has transformed into a "push center," with variables coming from AI, allowing users to quickly open functions and products through conversations with an AI smart partner (a chatbot).
