这两天除了芯片大会火热，医药大会也有爆炸性利好：

美国肿瘤学会年会上，全体起立鼓掌，是因为Daraxonrasib这款靶向药公布了临床数据，将胰腺癌的死亡率降低了60%，副作用远小于化疗

这是30年来最大历史性突破

开发的药厂 $RVMD 近一年股价涨了超500%，完全不输热门的AI赛道

这款药预计美国今年Q3上市，中国上市预计在明后年

I posted a video last week introducing claude-trace and https://t.co/D0HNJLyict on my social media (xiaohongshu/douyin/wechat video), it went viral instantly, more 500k views and than 100K likes + bookmarks. However lots of audience report that claude-trace does not work on latest version of Claude Code because it went from npm installation to bun binaries so the monkey patch approach stop working. Wondering is there any plan to fix this? Really appreciate the work and I love claude-trace and cchistory. @badlogicgames

this OpenClaw bot finds restaurants with ugly menus, rebuilds them as live web menus, and mails the owner a postcard...on autopilot.

here's how agencies can land recurring contracts with this system:

- scrapes every restaurant in a city in real time
- filters by review count + rating + last menu update + photo quality
- pulls the real menu items from the official site, PDF, or Google reviews
- samples the brand palette from the restaurant's own visual identity
- renders a 9:16 brand-matched menu, hosted live at a QR-accessible URL
- writes a personalized postcard referencing a real reviewer and a real dish
- mails it to the registered office addressed to the owner by first name

every step from discovery to brand-matching to outreach is automated.

reply "MENU" + RT and i'll send you a free guide so you can build this too

@satofishi @grok answer the question

[ClaudeDevs @ClaudeDevs]

Over the past month, some of you reported Claude Code's quality had slipped. We investigated, and published a post-mortem on the three issues we found.

All are fixed in v2.1.116+ and we’ve reset usage limits for all subscribers.

今天去诊所见我的GP（全科医生），突然发现他桌上有个巨大的专业麦克风，一时好奇问他难不成还在诊所搞直播？😅

他一头黑线的告诉我这是最近添置的AI工具，帮他节省了大量的工作时间。

我还真的很惊讶怎么落后的土澳已经AI直接进一线诊所了？？立马追着问了半天。原来这东西的作用是AI自动记录患者的病历，而且能自动以当前主流的病历档案格式整理好。

了解医疗行业的小伙伴应该知道，医生的大部分工作量并不是给患者看病，而是写病历。不夸张的说，大概有60-70%的时间是花在这个上面，尤其是病情比较复杂的时候。

现在GP说他基本把Mac一开，患者走的时候病历就自动写好了，他只需要扫一眼稍微纠正一下就完事，效率大大的提高了。

我震惊的问难道现在澳洲诊所都普及这个了吗？他哼了一声说这都是私家诊所自己买的，公立医院可没有这待遇，但他觉得钱花的值。

一直以来我都觉得AI创业赚钱就应该是深入行业应用里去做定制化产品，上个月还在跟朋友聊Golf领域的应用，结果今天直接看到人都已经做好卖出去了，还是医疗这种有壁垒的行业，还反馈不错。。。。

突然觉得屁股有点烧，不能再划水等行情了，得动起来，不然就晚了😳😳😳

Wow. Incredible amount of SOTA training data now just available to China thanks to @mercor_ai leak. Every major lab. Billions and billions of value and a major national security issue.

[will depue @willdepue]

和我的许多朋友一样，我在 2026 年伊始就立下了一个目标：今年要变得更加中国人，而我也打算真正把它落实下去。在 OpenAI 工作将近三年后，我决定离开，去追求新的机会。

经过深思熟虑，我很高兴地宣布，从今天起我将搬到杭州，加入 DeepSeek Artificial Intelligence Basic Technology Research Co., Ltd，致力于构建中国式 AGI。

我实在无法拒绝这个让我成为亿万富翁（人民币）的机会，而深入布局、确保自己在未来半导体供应链中的控制力的机会，同样让我无法放弃。作为 DeepSeek 的首位多元化招聘员工，我已被承诺将获得 1024 块“走私”来的 B200。

来自杭州与中国香港特别行政区的问候。四月快乐。

Just cloned the repo, not sure if this is legal, but as friendly reminder, don't copy or fork it, might lead to github account suspension.

Claude code source code has been leaked via a map file in their npm registry!

[ZhangChi @zhangchitc]

I couldn't figure out why I never got /remote-control feature. Turns out I had CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1 set months ago from some "must-have config" article. That flag also disables release notes and update notifications — so I was never prompted about new features.

If you set this flag and feel like you've been missing out, now you know why. The flag doesn't do exactly what it says, the "nonessential traffic" includes things probably essential to you.

[Noah Zweben @noahzweben]

Announcing a new Claude Code feature: Remote Control. It's rolling out now to Max users in research preview. Try it with /remote-control

Start local sessions from the terminal, then continue them from your phone. Take a walk, see the sun, walk your dog without losing your flow.

I am trying to intercept Claude Code network request to understand the underlying behavior, @sergeykarayev 's finding is awesome, he leveraged HTTP Toolkit to do MITM proxy and you can the actual system prompt and Claude Code Tool setup. super recommended

[Sergey Karayev @sergeykarayev]

I wanted to better understand how Claude Code is wired under the hood, so I captured its API requests and pulled out the system prompt and tool definitions.

Also posting the full thing as a gist below if you want to dig in!

@petergyang We are using Claude Code and Codex, though pretty hard... Please let me know if need any help when you are in China. I use Claude Code daily and created lots of 100k+ view posts on xiaohongshu/douyin, something like: https://t.co/YP3epD3I9J

I posted a video last week introducing https://t.co/jn1T5ssWIS on my social media (xiaohongshu/douyin/wechat video), it went viral instantly, more 100k views and than 10K likes + bookmarks. The moment I made the video the github repo only 4.5k stars, now it has almost 10k, I am confident that probably because of my videos. Just want to say thanks for the great tool and sharing @jarrodwatts

Just did a full audit of my computer with Claude Code, with AI making supply chain poisoning worse, we desperately need a AI defense side solution. Andrei said he mostly vibe code little utilities himself, but that does not apply to everyone, wondering what better solution with economic incentives for someone to solve this?

[Andrej Karpathy @karpathy]

Software horror: litellm PyPI supply chain attack.

Simple `pip install litellm` was enough to exfiltrate SSH keys, AWS/GCP/Azure creds, Kubernetes configs, git credentials, env vars (all your API keys), shell history, crypto wallets, SSL private keys, CI/CD secrets, database passwords.

LiteLLM itself has 97 million downloads per month which is already terrible, but much worse, the contagion spreads to any project that depends on litellm. For example, if you did `pip install dspy` (which depended on litellm>=1.64.0), you'd also be pwnd. Same for any other large project that depended on litellm.

Afaict the poisoned version was up for only less than ~1 hour. The attack had a bug which led to its discovery - Callum McMahon was using an MCP plugin inside Cursor that pulled in litellm as a transitive dependency. When litellm 1.82.8 installed, their machine ran out of RAM and crashed. So if the attacker didn't vibe code this attack it could have been undetected for many days or weeks.

Supply chain attacks like this are basically the scariest thing imaginable in modern software. Every time you install any depedency you could be pulling in a poisoned package anywhere deep inside its entire depedency tree. This is especially risky with large projects that might have lots and lots of dependencies. The credentials that do get stolen in each attack can then be used to take over more accounts and compromise more packages.

Classical software engineering would have you believe that dependencies are good (we're building pyramids from bricks), but imo this has to be re-evaluated, and it's why I've been so growingly averse to them, preferring to use LLMs to "yoink" functionality when it's simple enough and possible.

My video about Ghostty on xiaohongshu/douyin/wechat video just crossed 200k views with 10k+ likes, comments, and saves — honestly didn’t expect this level of response.

What surprised me most is how many people resonated with the feel of Ghostty, been using it alongside Claude Code and it’s become a core part of my workflow.

Huge shoutout to @mitchellh for building this — excited to see where it goes next 🚀
