Cai Chongxin’s divorce topped trending searches, followed by a reversal of the “new romance rumors”—here’s what happened!
In early August, Alibaba Group Chairman of the Board Cai Chongxin and his wife Wu Minghua announced the end of their nearly 30-year marriage. After the divorce news was announced, photos allegedly showing Cai Chongxin “dating” and having a “new love” also circulated online, sparking heated discussion.
However, these two matters should be considered separately: the divorce has been confirmed by both parties, while the so-called “new romance” currently has no reliable evidenc

Simply feeding a PDF into AI may cost more tokens than you think.
Because AI doesn’t just read text—it also analyzes the layout, tables, images, and page structure inside the file. You’ll retain information more completely, but the cost will also go up.
If you only want AI to quickly understand the document content, you can first use the open-source project MinerU to convert files like PDFs, images, Word, and PPT into Markdown.
Text, tables, images, and some layout information can all be preserved. Then, handing the cleaned-up Markdown to AI typically saves more tokens and also makes it easier

Compiled 4 open-source tools that are great for office workers, each solving common high-frequency problems: interview expression, meeting notes, recalling information, and submitting job applications.
Textream: a hidden teleprompter for interviews and presentations
It floats at the top of the screen, tracks what you’re saying in real time via voice, and only shows prompts on your own screen.
For online interviews, project updates, or impromptu speeches, you don’t have to keep looking down at a script, and it also helps reduce forgetting lines and stuttering.
Meetily: auto-organizes key points

Today, TencentDB-Agent-Memory, which is trending quickly on GitHub, solves the problem of AI “forgetting” (memory loss).
For many people’s real AI Agent experience, it really boils down to one sentence:
It’s smart, but it always feels like it forgets.
In the same background, it has to be explained again,
the same preferences have to be repeated,
and the same SOP gets run through twice—then it forgets.
This project addresses these issues:
It aims to make AI Agents not just “answer well in the moment,” but truly start building usable long-term memory.
Why is this important?
Because what really s

Many people building AI applications start by competing on the model.
But once you actually get the product up and running, you realize the hard part is often not "generation," but "getting the data."
Firecrawl, which is rising fast on GitHub Trending today, is essentially solving this problem.
It gained another 834 stars today, bringing its total stars to 146k.
In a nutshell:
It's not just a regular crawler—it directly organizes web content into context that AI can digest more easily.
For example:
Search web pages
Extract main text
Convert to Markdown
Output structured JSON
It can even intera

Micron MU: Is it worth buying now? Here's a simple analysis.
MU is undoubtedly a high-priority target among AI storage bottleneck stocks, but in the short term, it's not about catching up at low prices; it's a crowded trade driven by high expectations before earnings reports.
Core logic
Micron's real bottleneck isn't ordinary SSDs/consumer memory, but AI servers' HBM, high-end DRAM, and enterprise storage.
As AI computing power continues to expand, GPUs are not just short of chips but also lack high-bandwidth memory and sufficient data center storage.
The main global players in this

Now designers are really about to lose their jobs. With just one sentence, you can create a poster that rivals that of an experienced designer using @dappOS_com的新产品 @xBubble_ai.
The key point is that I am not someone who knows how to write AI prompts; on the contrary, I am a beginner. AI tools like xBubble that focus on results are just too easy to use.
Previously, with Midjourney, if the prompt was poorly written, the output was very abstract, requiring repeated adjustments, which took a lot of time and still often wasn't satisfactory.
This is not just my problem but a pain point in the cur

Having a girlfriend is quite expensive, but luckily today she treated me to hotpot, feeling great.
There's nothing that can't be solved with a hotpot meal.
The problem is, after eating hotpot, she pouted and acted cute,
and I immediately bought her two sets of clothes.
Turns out, men are easy to manipulate. 😆
