作者通过 Cursor AI Editor 快速开发了一个原生 Mac App: VideoSearch,可以搜索视频中出现过的文字。除此之外连截图、说明文案、网页等都可以通过 Cursor 来完成。

该视频演示了他是如何使用 Cursor 来进行开发的,对于没太接触过 Cursor AI 编程的同学应该会有不少启发。

我之前一直纠结于 Xcode 不支持 Cursor,看了视频后,发现解决方案页挺简单的,就是把项目通过 Cursor 打开,然后在 Xcode 中运行,报错后,再回到 Cursor 让它解决。

独立开发的奥义是:粘住一撮用户(包括自己)。目标用户见了之后就有使用的欲望(Marketing),用了之后就离不开(Product)。

Marketing 层面:因为用户的时间是有限的,因此要在极短的时间内把「产品是什么,为什么你应该使用」这件事说清楚,可以通过 landing 页,或方便传播的短视频来实现。「让目标用户看见」可以有很多种方式,最直接有效的,就是通过自己的社交媒体圈来传播,并且让其他人有忍不住分享的冲动。

Product 层面:最重要的是持续迭代,用户可以感觉到产品是活的,被得到足够的关注。选型方面可以往私人订制、有趣、小而美这几个点考虑,或者更直接点:大厂不会考虑做的产品。

洗冷水澡第三天。刚开始还是要 push 一下自己,但大概 5 秒钟就适应了,后面几乎没感觉到是在洗冷水澡(可能是水温还不够低)。

做产品很重要的一点是 keep it hot。代码乱一点没关系,产品差一点也 OK,只要持续地迭代就行。一旦放凉了,就不会想再打开,打开后也要好一阵才能重新热起来。

今天继续冷水澡,不过说是冷水澡,因为是在夏末秋初,所以真实温度应该有 20 度左右。

一开始还是会有点抗拒,但不给自己犹豫的时间,直接把水龙头一开,站在下面 20 来秒钟,就基本适应了。

后面其实就还好,因为这是很难得的没人打扰只属于自己的时间,所以可以好好利用下。

这次持续了 10 分钟左右,出来后身体会微微发热,感觉还是不错的。

「言叶之庭」有看过两遍,一直被新海诚精美的画面所吸引,相比之下其中的故事倒没留下太深的印象。听过木鱼水心的解说之后,才发现原来导演藏了那么多的巧思在里面,好的作品果然是可以一品再品的。

鉴于在多个播客中都提到了洗冷水澡的好处,今天也实践了下。

虽然有点心理准备,但当冷水淋在身上那一刻还是会不自禁地哆嗦,前两分钟会比较难。过了这个阶段后,大脑就可以慢慢放飞,想一些事情,这时依旧会感到不适,但是是可以接受的那种不适。

擦完沐浴露后,再用冷水冲,就没那么难受了。别说,洗完之后状态还不错。斯多葛学派也有提到可以通过冷水澡,将自己的身体置于舒适区之外。

Concurrency Step-by-Step: A Network Request

When I was first learning to program I had absolutely no idea what I was doing. I was using C, and I remember desperately putting in * and & characters until things compiled. But, this was pre-Mac OS X. Upon running my horrifically incorrect programs, half the time the screen would become corrupted and the mouse would stop moving. I’d then have to reboot the whole machine via a physical switch. This was … frustrating.

这篇文章通过一个简单直观的场景(从网络加载图片并展示),演示了 Swift Concurrency 和使用 GCD 的差异。会涉及到基本的 Swift Concurrency 概念(如 @MainActory, isolation, async/await 等),没有太深入,但能知道大概是怎么回事,以及如何使用。对于刚接触 Swift 并发的同学来说,非常友好。

Andrew Huberman 关于多巴胺的一期视频,2 个多小时,非常推荐。以下是我的一些摘录:

Dopamine has everything to do with how you feel right now, an hour from now, your level of motivation, your level of desire, and your willingness to push through effort.

Dopamine is the primary determinate of how motivated we are, how excited we are, how outward facing we are and how willing we are to lean into life and pursue things. It's responsible for motivation, drive and craving primarily.

Dopamine is vitally important to movements

Dopamine impacts mood and motivation.

Many drugs and indeed many supplements that increase dopamine will actually make it harder for you to sustain dopamine release over a long periods of time.

How satisfying or exciting or pleasureful a given experience is, doesn't just depend on the height of that peak, it depends on the height of that peak relative to the baseline.

Just increasing your dopamine, it will make you excited for all things. it will make you feel very motivated, but it will also make that motivation very short-lived.

Dopamine doesn't work on its own. Neurons that release dopamine co-release glutamate, which stimulates neurons to be electrically active. it tends to increase our levels of alertness, readiness and desire to pursue things outside the confines of its skin.

If your dopamine is somewhere in the middle, how you feel depends on whether or not you had higher dopamine a few minutes ago or lower dopamine. you experience of life and your level of motivation depends on how much dopamine you have relative to your recent experience.

Chocolate will increase your baseline level of dopamine 1.5 times. sex (pursue or act) increase dopamine two times. Nicotine(smoked)/Cocaine increase dopamine two and a half times above baseline. Amphetamine will increase the amount of dopamine in the bloodstream 10 times above baseline.

As we start to engage with something more and more and what we say about it, what we encourage ourselves to think about it, has a profound impact on its rewarding or non rewarding properties.

Often times we are feeling good because we are layering in different aspects of life, consuming things and doing things that increase our dopamine. but afterward the drop in baseline occurs, and it always takes a little while to get back to our stable baseline.

There's a pool of dopamine that synthesized and you can only release the dopamine that's been synthesized. It's the readily releasable pool.

The problem is that dopamine is not just evoked by one of these activities, dopamine is evoked by all of these activities. And dopamine is the one currency of craving motivation and desire and pleasure.

The way that you replenish the releasable pool of dopamine is to not engage in these dopaminergic seeking behaviors.

Not expect or chase high levels of dopamine release every time we engage in these activities. intermittent reward schedules are the central schedule by which casinos keep you gambling. Intermittent schedules are the way that the internet and social media and all highly engaging activities keep you motivated and pursuing. That intermittent reinforcement schedule is actually the best schedule to export to other activities.

Just do the exercise. Don't do the exercise and expect dopamine to arrive. If you want to maintain motivation for school, exercise, relationships or pursuits of any duration in kind, the key thing is to make sure that the peak in dopamine, if it's very high, doesn't occur too often.

The whole basis of intermittent reinforcement is that you don't really have a specific schedule of when dopamine is going to be high or low. try removing multiple sources of dopamine release from activities that you want to continue to enjoy.

Taking ice baths, exposing oneself to cold water of various kinds can have tremendously beneficial results on your neuromodulator systems, including dopamine. it's a sustained rise in dopamine that took a very long time up to three hours to come back down to baseline.

The effort part is the good part, not the reward or trophy.

电商的美国游戏,靠卷赢不了

Temu 从来不只是一个关于电商的游戏,更是一个有关城市规划与国家发展的隐喻。

非常细致的一篇关于 Temu 进军美国的分析文章。从中可以一窥电商的工作原理、要点、成本项,以及 Temu 与美亚的差异化竞争。不得不说,电商真的非常复杂,要考虑的因素很多,非常考验战略和执行。

Temu 作为后起之秀,在美国远没有亚马逊那样完善的仓储和物流体系。所以它更多依赖于以轻小件的形式,直接走空运发到美国,然后交给仓储和物流公司。这一方面让 Temu 要比亚马逊多几倍的时间送货,而 75% 的美国消费者愿意支付额外费用以更快地获得商品。

为了解决物流问题,亚马逊依靠十余年的时间在全美建设了 110 个配送中心。有的大型配送中心比故宫还大,里面有一千五百个全职员工。

而 Temu 完全相反,这些加入半托管的卖家们发现发任何信息都有人秒回、有专职人员会教他们如何上新、如何维护链接;Temu 选品的买手也会提前通知这些卖家,告诉他们平台下一步会推什么。有商家说 Temu 的运营和他保证,只要能每天上新一定量的 SKU,就会一直给首页流量。也有商家说 Temu 的运营会指导商家如何上架那些亚马逊不收的商品,整体上要比亚马逊灵活很多。最重要的是 Temu 会帮商家买流量、引流量;亚马逊只会给自己买流量,而平台上的商家则基本分不到亚马逊花钱买广告所带来的流量。

一面是热情似火的 Temu 客服,凡事靠微信都能商量清楚;另一面是干什么都麻烦的亚马逊。中国卖家自然更倾心 Temu。

这也为什么 Temu 在相当长的一段时间里只允许中国和香港地区的卖家开店,因为这足够了。Temu 用中国工厂、亚马逊不要的库存和原本就是他们供应商的中国大卖,以极致的低价从贝佐斯的国度撕开了一条裂缝。

大家都在利用同样的工厂生产商品、同样的卖家在卖货、同样的物流运到美国,这里最耗费成本的关卡也类似:最后一英里。因为美国人可以为了降低成本把一切都转移到境外,唯独最后一英里是实打实的需要在美国境内处理的美国问题。电商游戏追求便宜,把一切成本剥开后,最后一英里依然屹立在成本中心。Temu 无法在这里把全部环节都变成它在国内的供货商那样任其摆布。任何人想要把这个游戏玩的更好,就一定要面对这个问题。

人工成本的挑战是送货的效率,但效率无法无限提高。归根结底,挑战的本质是美国城市规划。Temu 无法像拼多多在国内卷卖家一样的靠卷来解决这个问题,因为最后一英里不是个商业问题,是社会问题。社会问题就像是天气,要面对它。

在美国人眼中 Temu 不光是便宜,而是定位为一个便捷可靠的在线市场,满足消费者的生活便利需求。这样 Temu 在美国有了丰富的用户圈层。但总体而言在美国低收入家庭更有可能在 Temu 购物。任何凭借更低的价格争夺市场份额的平台,受众都注定如此。

快递员们互相分享在 Hood 配送的经验。不过就算是新人,他很快也能学习到其中的技巧:因为几乎每个 Hood 里的订单都会在备注里写上注意事项。最常见的是绝对不要放在前门,永远不要,放了很快就会被人偷走。实际上,Hood 里的很多业主回家都不使用自家前门。

这就是 Temu 和所有电商都要面对的问题。这也是为什么妄想靠机器人和无人驾驶来全面解决送货是不可能的。面对如此复杂的情况却依然认为可以靠机器取代人,要么是愚蠢,要么是无知。既然能融到资的创始人并不愚蠢,那就只能说明大部分生活在良好社区的科技从业者从来不知道这个国家另一部分居民的现实生活。

Software estimates have never worked and never will

Since the dawn of computing, humans have sought to estimate how long it takes to build software, and for just as long, they've consistently failed. Estimating even medium-sized projects is devilishly difficult, and estimating large projects is virtually impossible. Yet the industry keeps insisting that the method that hasn't worked for...

为什么「给软件开发估时」这事不靠谱。因为软件开发很大一部分是与未知打交道(比如一个很小的 Bug,可能需要好几天才能找到头绪;一个小改动可能影响很多模块;很多边缘场景要考虑等等),未知的事物如何估时?

The fundamental problem is that as soon as a type of software development becomes so routine that it would be possible to estimate, it turns into a product or a service you can just buy rather than build.

应用到数码世界的话,这个 Holding Pen 大概就是 Quick Inbox,可以一个快捷键呼出,记录下脑海中想到的事情。

Paul Graham 在这篇文章中提到了 "Founder Mode",与之对应的是 "Manager Mode",提出这个概念的背景是一次 YC 会议上的分享。

创业公司在进入增长期时,通常会有「好心人」站出来,让他们 "Hire good people and give them room to do their jobs.",听起来没啥问题,但通常结果都不太理想。

这里就涉及到了两种 Mode:Founder Mode 和 Manager Mode。有一条评论说得挺好的:Founders have to care in a way that managers do not. Founders have to learn things managers do not. Failure to a founder is dream-ending. Failure to most managers is job-ending. Managers 通常做的事情是:

Treat subtrees of the org chart as black boxes. You tell your direct reports what to do, and it's up to them to figure out how. But you don't get involved in the details of what they do. That would be micromanaging them, which is bad.

下次面试时,也可以问下 CEO 每天的 Routine,以此来了解他到底是 Manager Mode 多一些,还是 Founder Mode 多一些。

I work from the moment I wake up to the moment I go to bed. I work seven days a week. When I'm not working, I'm thinking about working, and when I'm working, I'm working. I sit through movies, but I don't remember them because I'm thinking about work.
