【科学】一天当中什么时间喝咖啡更好?

与不喝咖啡相比,早上喝咖啡能使全因死亡风险和心血管疾病特异性死亡风险分别降低16%和31%。同时,咖啡饮用时间显著改变了咖啡摄入量与全因死亡率之间的关联;在早上喝咖啡的参与者中,较高的咖啡摄入量与较低的全因死亡率显著相关。

文中给出了论文地址,这个研究是一个大样本量(4万人)长周期(20年)的研究,挺有说服力,结论是相关性而非因果,早上(研究中定义为早上4点到中午12点)喝咖啡的人死得更少。相关性的意思是也可能是这些死得更少的人的生活方式让他们早上喝咖啡。更有意思的是这些人喝的越多,死的可能性越低。所以,我们生活中无论什么因素会导致我们下午和晚上不得不靠咖啡提神,那就干掉这个因素,能多活几年。

【玩具】新款 Retroid Pocket Flip 2 游戏掌机发布:翻盖设计、5.5 英寸 1080P OLED 面板配天玑 1100

这个产品形态对我来说挺理想的,最近把 PSP 重新打开通关了 428:被封锁的涉谷,PSP 虽好,但是屏幕如今看确实太小了。上面这个设备跑 PSP 模拟器大概率比 PSP 玩 PSP 游戏体验更好,不过天玑 1100 还是差点意思(但是它便宜啊)。PS:我没买,回头如果有天玑 1200 的话可能会考虑买。

【AI】Hallucinations in code are the least dangerous form of LLM mistakes

The moment you run LLM generated code, any hallucinated methods will be instantly obvious: you’ll get an error. You can fix that yourself or you can feed the error back into the LLM and watch it correct itself.
Compare this to hallucinations in regular prose, where you need a critical eye, strong intuitions and well developed fact checking skills to avoid sharing information that’s incorrect and directly harmful to your reputation.

文章的标题十分正确,不过正文主要在说如何避免那些编译器无法发现的 LLM 生成的错误代码。编程语言相比自然语言还是严谨很多的,所以更容易发现错误,在日常生产生活中使用 LLM 的会遇到更多难以发现的错误,但是因为自然语言天生的含义模糊的性质,有的错误没有那么尖锐(这也是 LLM 的优势)。

【苹果】New Mac Studio spans the generations with M4 Max, M3 Ultra chips

that M3 Ultra model instantly becomes the ultimate Mac for the person who has everything except the ultimate Mac. When fully loaded it’s got 32 CPU cores, 80 graphics cores, 512 GB of unified memory, and up to 16TB of onboard storage. Apple estimates that the M3 Ultra will be nearly twice as fast as the M4 Max in workflows that can take advantage of all that extra everything. (Who needs a Mac Pro? Don’t answer that.)

苹果出人意料的发布了个 M3 Ultra 的 Mac Studio,虽然号称性能是 M4 Max 两倍,但是内存带宽依然是 819 GB/s,这个可不是 M4 Max 两倍的水平,而 LLM 性能对这个挺敏感的。蹲一波性能实测再考虑要不要买吧,都做好心理建设买 M4 Ultra 了,整个这活确实有点下不去手。

【道理】 The More You Own, The More You Maintain

If every new feature just meant one more thing to maintain, things might not be that bad. But ten design components don't create ten relationships, they create forty-five potential interaction points to consider. Each new addition multiplies a system's complexity, not just adds to it.

标题是一个简单的道理,不只在软件设计和开发领域适用,家里的很多东西也是这样。前几天看到微信群里有人转日本 0 元一户建的消息,北海道的房子不要钱,但是买了之后要开始支付房产税(不太贵),房屋修缮费用(贵,而且修缮之后房产税可能会涨),冬季清雪费用,保持房子不坏的水电费用等等。小到家里很多不必要的东西(比如用不上的布艺清洗机,旧手机旧充电宝,孩子已经不玩了的玩具),都会增加日常生活的成本和风险。简单一点的生活更轻松和愉快

VisionOS 2.4 beta 看起来还挺吸引人的,Spatial Gallery 我需要,然后这个 iOS app 着实不错,过年回家给父母用 Guest mode 真的很麻烦,Reddit 上的老哥们最想要的也是苹果门店里的 Demo app,看起来四月有机会正式版。希望 Apple Intelligence 中国一起上线,切账号怪麻烦的。

【硬件】第一个明星 AI 硬件,将在下个月成为电子垃圾

Ai Pin 的制造商 Humane 被惠普以 1.16 亿美元收购,主要包括软件、技术人员以及 300 多项专利。如果你不幸拥有一台 Ai Pin,请务必提前将个人数据下载保存至本地,因为在 2025 年 2 月 28 日之后,Ai Pin 就再也连不上 Humane 的服务器,所有的 AI 服务、消息推送等联网功能都将失效,除了还能让 Ai Pin 播报剩余电量之外,这个产品已经一无是处。
最终,699 美元的 Ai Pin 只卖了一万多台(截止至 2024 年 8 月的销售数据)。而在这个产品刚发布时,也有不少人认为这就是 AI 时代的 iPhone。

这玩意发布的时候的热度依然历历在目,从 TED 起手,一路拉高预期,被全球科技媒体和自媒体狂吹,死于产品太差。硅谷的创业金句有一条:Fake it until you make it,Humane 这叫公司只做了前半段,能力太差,产品干得还不如小天才。对前因后果感兴趣可以阅读:Humane’s AI Pin: all the news about the dead AI-powered wearable

【AI】 The Deep Research problem — Benedict Evans

At this stage, the obvious response is to say that the models keep getting better, but this misses the point. Are you telling me that today’s model gets this table 85% right and the next version will get it 85.5 or 91% correct? That doesn’t help me. If there are mistakes in the table, it doesn’t matter how many there are - I can’t trust it. If, on the other hand, you think that these models will go to being 100% right, that would change everything, but that would also be a binary change in the nature of these systems, not a percentage change, and we don’t know if that’s even possible.
(...)
there’s also Steve Jobs’ line that a computer is ‘a bicycle for the mind’ - it lets you go further and faster for much less effort, but it can’t go anywhere by itself.

Ben Evans 一直以来对 LLM 的态度都是这样,这篇文章例子很具象,大模型在提供精准信息这件事上可能永远达不到人们的期望,但是在语言表达上确实也达到了传统方法无法企及的高度,了解工具的特性才能用好工具。用数据题给大模型评分没啥问题,非让它做题大可不必,计算器便宜又好用。我很喜欢他对乔布斯这个比方的解释的后半段,it can't go anywhere by itself. 至少可见的未来还是这样。

【软件】Pieoneer Your Apps in a Pie Menu

Product Hunt 上看到的一个启动器(launcher)产品,第一眼我的感受就是回到了 90 年代。小时候用 Win 97 上网冲浪很喜欢找类似的产品用,罗技鼠标自带一个和这个很像的软件。这么多年以来,一部分产品设计师对于围绕焦点的扇形/圆形菜单一直放不下。比如 Path app 搞出来的扇形菜单,后来 iMessage 也用了,但是后来又改回了列表菜单。

我理解拨号盘式的扇形菜单设计虽然理论上需要鼠标移动的距离最少,但是对阅读并不友好,和日常无处不在的列表交互范式不一致,也带来了额外的学习成本,而且鼠标多挪一点并不是什么问题。

不过如果使用场景确实无法进行大距离移动(比如残障人士),或者交互方式本身就是圆形的(比如摇杆)那就没什么问题。

【AI】Life Is More Than an Engineering Problem

泰德姜这篇关于 AI 的访谈很值得一读。

Magic means that the universe is behaving not as a giant machine but as something that is aware of you as a person who is different from other people, and that people are different from things. At some level, the universe responds to your intentions in a way that the laws of physics as we understand them don’t.

他对魔法的理解很有意思,可能因为魔法是人类编造的能力,所以他定义的魔法世界就是唯心世界:世界响应人的意图,而对应的是物理(真实)世界。

I don’t like the phrase “the alignment problem.” It’s not clear to me that it refers to something meaningful—or at least that the phrase refers to something that is new and meaningfully different from the broader problems of how to be a good person and how to build a good society. For example, when corporations behave badly, should we consider that an alignment problem? Most of the conversation around the alignment problem suggests that it’s a technical problem, something that can be addressed by implementing a better algorithm or by solving the right equations. But why, for example, do large corporations behave so much worse than most of the people who work for them? I think most of the people who work for large corporations are, to varying degrees, unhappy with the effect those corporations have on the world. Why is that? And could that be fixed by solving a math problem? I don’t think so.

对齐(alignment)这部分说的也很好,当一部分 LLM 从业者用「对齐」来暗示大模型输出违法/错误的内容完全是一个技术问题的时候,我感觉他们要么是跑偏了,要么就是坏心眼:价值观是多元的,站在不同立场上就会有不同的判断,如果 LLM 要符合某个绝对正确的价值观,那这个价值观可能也太二极管了。如果我们期望一个工具做价值判断,多少有点类似于要求菜刀只能切菜不能砍人。

Either way, you are only serving your own interests, and that’s fine because a chisel is just a tool. If you don’t keep it sharp, you are only harming yourself. By contrast, if you don’t respect your colleagues, there is a problem beyond the fact that it might make your job harder; you do them harm because you are ignoring their preferences. That’s why we consider it wrong to treat a person like a tool; by acting as if they don’t have preferences, you are dehumanizing them.

最后,如果 LLM 真的有了他们所说的 AGI、奇点的能力,会思考会学习能判断甚至有感情了(我认为不在未来二十年,甚至我有生之年应该都看不到),你就不能把它当工具了,那是奴役。当然现在做的 LLM 距离那玩意还远得很。我们在未来几年也许能把能听懂人话的工具做出来,已经可以改变世界了,至于那些听起来挺科幻的部分,主要是融资和公关需求,看个乐就行了。

This is how millions of Americans already work. Millions have no paid sick time at all (and even unpaid sick leave can be iffy) and millions more get less generous PTO than this.
The only remarkable thing is that this policy is bad for a tech company. Tech is special because demand for specialized workers is high and supply is low. But in most other industries, this would be standard behavior.
Workers in other industries deserve better, but it’s also important to remember that the HN bubble isn’t the norm.

DJI will no longer stop drones from flying over airports, wildfires, and the White House

大疆在全球各地都会设立禁飞区,有的是当地政府要求,有的是大疆主动为之,因为如果有人有意或无意的在某些地方使用无人机,对大疆的业务是长期有害的。

之前一直有这个传闻,大疆在美国要随心飞了,这两天做实了:

DJI voluntarily created its geofencing feature, so it makes a certain degree of sense that the company would get rid of it now that the US government no longer seems to appreciate its help, is blocking some of its drone imports, calls DJI a “Chinese Military Company,” and has started the countdown clock on a de facto import ban.

这篇文章几乎在直接指责大疆是在鼓励用无人机去撞救火飞机和白宫,也挺新闻学的。

这个结果对大疆和美国是双输,不过站在中国人的立场,我支持大疆试试这个魔法对轰的方案,毕竟中国企业在这场持久的霸凌中表现得太好欺负了。不过大疆表现的也是有礼有节,还写了一篇文章避免误会,大意是这时候推出这个方案不是因为政治因素,只是怎么管理飞行设备是政府的职责,企业会合规经营。
