我最喜欢的成瘾流行是“接住杯子里的绳子上的球”席卷了欧洲部分地区,以至于人们忽视了他们的工作。

有趣的是,识别什么引起人类注意的过程并不是什么新鲜事。

例如20 世纪 50 年代的卡通片旨在:

- 可爱的动物

- 短而快速的场景切换

- 朗朗上口的音乐

b/c 众所周知,上述三种因素都会欺骗人脑进入“静坐观察”模式。

焦点小组对广告做了同样的事情,然后演变成 A/B 测试以确定所揭示的偏好。

与导致快餐上瘾的整个脂肪/盐/糖研究一样。

这只是下一个合乎逻辑的步骤。

我仍然将它用于家庭项目,非常棒!

为虚拟机设置所有配置文件有点奇怪,但现在法学硕士让这一切变得轻而易举。

我经常在人员流动频繁的地方看到类似的情况。

团队负责人离职或被解雇,然后他们的项目就被随意分配给其他人。

这并不可怕。可怕的是没有交换或交易项目的机制。

> 任何成功企业的生命周期都分为四个阶段

我在接受采访时通常会说,我喜欢在第一阶段(启动)结束和第二阶段(组织)开始时加入一家公司。

没有什么比被告知 "嘿,我们已经开始运行了,但一团糟 "更让我高兴的了。现在我们需要有人把它变成一个易于修改和维护的系统"。

If people love to watch novel use cases of dashboard software like Grafana etc, I highly recommend this video about it being used at a water treatment plant: https://www.youtube.com/watch?v=wucMZ9tb1I0

This does exist btw.

It's a stainless steel coil that you can put on your A/C and then run water from your pool over it to heat the pool.

I don't know about in swimming centers in England but I do know YMCAs in the US often have budgets that look like:

- Revenue: $25.01M

- Expenses: $25M

So "small savings" like this can add up for them.

We used to (and still do) have things that could run commands and interpret them. These things would sometimes forget key parts to run or even forget to run them at all. So we invented a system where you could give instructions (code) and schedule when they would be run (cron etc). Those things were called humans.

There is a great article called "Manual Work is a Bug" [0]. The idea is that you have humans doing a lot of random things so you should:

- first make a list of the things they are doing

- then update the list with the commands they have to run for each step

- some of the steps won't have commands b/c it's things like "ask Bob what the limit should be"

- over time, the commands become scripts

- then the "ask Bob" becomes an API call

- one day, the whole thing is an automated system that runs code

People like to think that LLMs can do all of the above. I don't get this b/c code is deterministic and can be run repeatedly basically "for free" (at least compared to token spend).

I do think that LLMs can greatly accelerate the creation of the code/system etc and can also help with maintaining it but the whole "we will just version control the prompt" was clearly hogwash.

Took my kids to see Toy Story 5.

While watching it, I thought about AI generated content.

I have never personally met anyone who worked on any of the Toy Story movies. I know, from documentaries etc, who Brad Bird and John Lasseter are. I've also watched the video [0] about how Toy Story 2 almost got deleted (which I highly recommend if you are in storage, DevOps or SRE).

There are other movies like the Wild Robot that:

- had big emotional impact on me (b/c I'm a parent)

- are 100% animated

- I have zero idea who made them

I say all of this b/c at some point, most people don't care if the movie was hand painted cels, CGI done by humans or fully AI generated with human text prompting. If the feeling is strong, people will have a "bigger" reaction which in turn will make it more memorable. It's all basically on a spectrum of "humans using tools". They care about how the movie makes them feel. It started with humans spitting charcoal at a wall [1] and now it's linear algebra.

Apparently in the military, special forces in particular, this is even worse.

If you have a terrible soldier in a Tier 1 unit and you are trying to get rid of them via transfer to another unit, when asked why he is transferring you can just say "sorry, that's classified". The receiving unit then has no idea of the problems associated with that soldier.

There used to be great writing in magazines and people paid for those.

In fact, Playboy is famous for having excellent authors write articles or do serials. This is my favorite example of "you can be 'good' at two wildly different disciplines"

Atul Gawande, of Checkslist Manifesto [0] fame, has a great article about the Cheesecake Factory [1].

He mentions that that they have a model that can predict both guest numbers and revenue:

“We have forecasting models based on historical data—the trend of the past six weeks and also the trend of the previous year,” Gordon told me. “The predictability of the business has become astounding.” The company has even learned how to make adjustments for the weather or for scheduled events like playoff games that keep people at home."

And this was in 2012!

I highly recommend both the book and the article as both talk, in detail, about how to build systems even in very dynamic environments.

I can only imagine how accurate the models have gotten now.

I'm always fascinated by these tricks of game theory.

e.g. in business school, the dean of the undergraduate school had this story:

"When I was a practicing lawyer working on wills and estates, people would often ask me to cut someone completely out of their will.

I would always say that a better option was to write something like 'To my daughter Susan, I leave $1,000. She always said that she wanted to be financially independent from me so this is an amount to show her I lover her.'

Clients would always think this would send the wrong message and I would replay:

'No, no. If Susan fights the will and says she should have gotten more, the judge will say: but she clearly left you something and pointed out that she loved you AND took your wishes into account' "

I wish there was a book or collection of these types of tricks to study.

I was born with no sense of smell [0] and I always wondered if I could combine that with my tech skills to be CTO at a place like the screwworm factory or possibly Waste Management.

One of my favorite recently learned facts about Congress:

Federally mandated parental leave (paternity and maternity leave) polls at about 80% in favor with the US adult population. This is regardless of political affiliation, by the way. Democrat and Republican voters both support it.

Upon reading this, you might be surprised as to why it's NOT federally mandated given how popular it is.

One group it's NOT popular with is corporations. And corporations donate a lot of money to politicians. And it's cheaper to donate to politicians who are against parental leave than it is to pay people for that parental leave.

I enjoy sharing this b/c it's a reminder that there are groups who spend a lot of time and money to get their way. At first, that might feel overwhelming. You might be surprised to know that when you call your local congressperson, those calls gets tallied b/c they want to know what their constituents care about. So give them a call and let them know.

So I was an intern at Merck MANY years ago and they had this interesting comparison.

Most companies only publish medical research findings on blockbuster drugs once both are true:

1. Production has started

2. A patent has been filed

The reason for this is that they want to maximize the amount of production time under patent b/c that maximizes revenue.

If you are the researcher, that means you have to wait until all of the production setup is ready to go.

Merck took a different stance.

There, the patent was filed as soon as the researcher was ready to publish. This meant that there was less time under patent for production but was much better for the researcher as they got their findings out earlier.

The thinking was that being able to publish earlier would attract better researchers and in turn would lead to better drugs, more revenue, more profits.

This was in the late 1990s so not sure how this plan worked out as I haven't been in pharma since that era.

Would be interesting to hear from other folks more knowledgeable.
