一 | The USS Carney, a U.S. Navy guided-missile destroyer in the northern Red Sea, on Thursday shot down multiple missiles and drones launched by Iranian-backed Houthis in Yemen that the Pentagon said were potentially headed toward targets in Israel.It is the first time in recent memory that a U.S. Navy ship in the Middle East has engaged missiles and drones that were not directly aimed at the vessel.It's also the first U.S. military action taken to defend Israel in the current crisis and with the U.S. and other countries trying to contain the conflict between Israel and Hamas, the possibility that an Iranian-backed proxy group fired missiles and drones at Israel is sure to increase growing regional tensions.The ship was in the northern Red Sea on Thursday evening local time when it intercepted three land attack cruise missiles and several drones, Pentagon spokesman Brig. Gen. Pat Ryder said at a press briefing. U.S. officials told ABC News that the Carney had brought down eight drones launched by the Houthis.The preliminary U.S. assessment was that the USS Carney was not the target of any of the Houthi missiles or drones, according to multiple U.S. officials."We cannot say for certain what these missiles and drones were targeting but they were launched from Yemen heading north along the Red Sea potentially to targets in Israel," said Ryder who added that information about the engagements was still being processed.It’s unclear from where the Houthi militia's missiles were fired but they were headed in a northerly direction, an official said.The Houthis are an Iranian-backed Shiite movement that has seized control over much of northern Yemen and has been at war with recent years while Yemen has been at war with a Saudi-led coalition since 2015.As part of that conflict, the Houthis have launched missiles and drones deep into Saudi Arabia, but it appears that the missiles intercepted on Thursday were not aimed at targets inside Saudi Arabia.Last week, Houthi leader Abdel-Malek al-Houthi was quoted as saying that if the U.S. directly intervened in the Gaza conflict his group would respond by firing drones and missiles, and take other military options."There are red lines when it comes to Gaza," he said.Thursday's incident occurred during the early evening hours (local time) when the missiles and drones were detected moving northward above the waters of the Red Sea.The missiles fired by the Houthis were engaged by SM2 missiles carried aboard the USS Carney, a U.S. official told ABC News. No information was released about what weapons platform aboard the Carney brought down the 8 drones.Brig. Gen. Ryder told reporters that the intercepts had taken place over water and not land. No sailors aboard the ship were harmed according to a U.S. official.The United States has boosted its military presence in the region since the start of the Israel-Hamas war nearly two weeks ago.The USS Carney is part of the USS Gerald R. Ford carrier strike group that was deployed to the eastern Mediterranean to deter Iran and Hezbollah from joining the Israel-Hamas war. Defense Secretary Lloyd Austin recently extended the deployment of the Ford strike group so it can remain in the eastern Mediterranean and had ordered the deployment of additional fighter aircraft to U.S. airbases in the region.To increase U.S. deterrence of an expansion in the conflict the Ford will soon be joined in the eastern Mediterranean by the USS Dwight D. Eisenhower carrier strike group that left Norfolk, Virginia on Saturday and could arrive in the region over the next 7 to 10 days."By posturing these U.S. naval assets and advanced fighter aircraft in the region, we aim to send a strong message intended to deter a wider conflict to bolster regional stability and of course to make it clear that we will protect and defend our national security interests," Ryder told reporters Thursday.The USS Carney had just transited into the Red Sea through the Suez Canal on Wednesday which is why the destroyer was still located in the northern stretch of that body of water that borders, Egypt, Egypt's Sinai Peninsula, Sudan, Saudi Arabia, and Yemen.The missile shot down by the USS Carney will bolster the deterrence in the region and demonstrate that the show of force is serious stuff, a senior U.S. official told ABC News.The risk to U.S. forces and U.S. interests in the region has increased particularly in the wake of a deadly explosion at a hospital in Gaza earlier this week that inflamed regional tensions.On Wednesday, three drones were shot down by U.S. military forces as they neared bases in western and northern Iraq, another drone was shot down near U.S. forces in eastern Syria on Thursday.A U.S. contractor sheltering in place at one of the bases in Iraq died of a cardiac arrest in one of the incidents.Al Asad airbase in western Iraq experienced indirect fire on Thursday according to a U.S. official.The Carney's shootdown of Houthi missiles opens up the possibility that the U.S. Navy may have to position more ships in the Red Sea if the U.S. commits to protecting Israel from a southern attack said Steve Ganyard, an ABC News contributor and a former Pentagon official."The larger concern is if Iran now considers U.S. ships fair game," said Ganyard. "Because if the Houthis shoot at a U.S. ship there will be little doubt that it would have been at Tehran’s direction.""That said, there is nothing to suggest, no known reason to believe that Iran wants a fight with the U.S. and/or Israel," said Ganyard. "So, hopefully things calm down."ABC News' Martha Raddatz contributed to this report.。

Anthropic把自家员工入职培训的那套课程,原样搬到了网上。就在昨天,Claude Academy正式上线。
289个资源:课程、教程、真实用例全在里面,从「AI到底是什么东西」一路到Claude Code、API、MCP、agents和生产级部署。最重要的是,注册一个免费Claude账号就能看,学完发结业徽章,可以公开验证,也能挂到LinkedIn上。按照博客上的说法,本来这些内容原本是给新员工入职培训上的。

从零通关Claude CodeAnthropic 表示每天有数百万人跑到他们的官网上学习怎么使用 AI,公司为此还专门养了一支教育团队。Claude Academy就是这支教育团队的总入口。零基础的可以先搞清楚 AI 能干什么,然后上手对话、Cowork这些。想写代码的更直接。Claude Code从入门到实战课都摆在那儿,再往后就是API、MCP、agents,一路到把东西部署上线。
课程还按人群分了岔路,写代码的、老师的、搞公益的、开店的,各走各的。底下有一门通识课大概14节,相当于整个体系的地基,不管你是谁都建议先过一遍。
装上Claude Academy Skill,它还会照着你的习惯和进度,直接告诉你下一步该看哪个。
最硬的一块:入职第一天学的4D框架整个Academy最核心的东西,是Anthropic和Rick Dakan、Joseph Feller两位教授一起开发的 AI Fluency 4D框架。简单说就四件事:Delegation——哪些活交给AI,哪些自己干。Description——把需求和过程说清楚。Discernment——挑剔地检查AI交回来的东西。Diligence——用得负责任,并且告诉别人AI在里面做了什么。Anthropic 的新员工入职第一天就要学习这个框架。它练的不是怎么写 Prompt,而是怎么判断哪些活该给 AI,哪些要自己干。还要学习 AI 最容易在哪些地方犯蠢,免得被带到沟里。
入职之后这些培训也不会停,他们管这叫「ever-boarding」。说白了就是没有「结业」这回事,因为AI的能力边界一直在变,人的认知也得跟着刷新。活到老,学到老。教育团队讲了一件挺反常识的事:具体技巧正在快速贬值。

二 | 以前你得先告诉Claude这份东西是写给法务同事看的,现在它自己就会来问你了。模型在进化,昨天的最佳实践今天可能就是多余动作。
所以他们把重心从教动作挪到了「养心智」,翻来覆去就这两句话——今天的AI,是你这辈子会用到的最差的AI。按风险高低决定验证力度。课程还专门提醒,别把自己在意的本事全交出去,那会使技能萎缩。比如,敏感的内容还是要自己写,汇总幻灯片丢给AI;探索性的数据分析交给Claude跑,但最后的核对还是要自己来。

这已经不是教你怎么使用工具那么简单了。这是在学习如何跟一个越来越强大的非人类队友相处、配合。

竞争已经换了赛道官方@claudeai那条帖子发出去几小时,点赞过万,转帖上千,浏览量冲到百万级。
网友@hiro44_pino连夜写了长帖,说289个资源不用全啃,每天看一点,立刻拿来实践。先用官方免费教材就够了,比买高价课划算得多。实用派给了更短的路线:先看7分钟的The 4 Properties of AI,再拿手上的活试一个具体的场景,卡住了再回来补长课程。有网友表示课程还是很实用的,自己连续 6 个月每天使用 Claude,还是能在高级课程中学习到新的技巧。
开发者 Kadam 认为,这种免费资源是一种巨大的胜利。

四 | 像 Claude Code 这样的工具教程对优化很有用。
当然也少不了阴阳怪气的声音,说这是教你如何更高效地被AI取代自己。
模型在往前跑,人得跟上这件事真正值得琢磨的地方在于:它动摇的不只是AI培训市场,而是整个「学习」这件事的逻辑。

五 | 传统教育体系是先花四年打基础,再用经验慢慢长。

六 | 但AI的能力边界每几个月就刷新一次,你半年前学的prompt技巧可能下个版本就内置了。

七 | 知识的保质期从没这么短过。
Anthropic的解法是,不教你记招式,教你练心法。不教你按哪个按钮,教你判断什么时候该按、什么时候该自己来。4D框架的底层逻辑说穿了就一句话:人要永远比工具多想一步。Anthropic把新人第一天的课免费放出来,其实是在说一件事:光是模型变强没用,用的人跟不上,白搭。那句「今天的AI是你这辈子会用到的最差的AI」,反过来读更扎心:它明天一定会更强,而大多数人的用法,还停在昨天。
