Why Do You Suppose Bing, but not Google Can Hack this Search?

When you search for Eugen Doctor's 1908 pamphlet, “Emigration and Immigration—A Word on the Plight of Jewish Emigres," Google serves up junk, while Bing can actually point you to the work - ironically, some of the copies being on Google's servers. Why do you suppose this is?

Why? Just finishing up Goetz Aly's "Europe Against the Jews," which had been on my list for a while - and he mentions this one.

Now That's a Gem - Productivity Hack - Lead Time Planning

Brett Arends : https://www.forbes.com/sites/brettarends/2014/06/02/ten-things-i-learned-at-mckinsey-co/#260007cd5c7f

A manager once told me his number one personal productivity tool was sitting down for ten minutes, at the end of every work day, and writing out his to-do list for the next day.

I remember something similar in "How to Stop Worrying and Start Living" by D Carnegie - the laggards leave the office early to "go spend time with the family" whereas the go-getters plan the next day.

Shame on me though :)

But, wait! What are the ten things this person learned at McKinsey?

1. There are no experts in business - they've just mastered the "act". There's a reason they pay these young smart consultants from McKinseay and Bain.
2. The answers are usually hidden in plain sight. That is, the information is accessible. It takes so analysis to convert it into actionable insights.
3. MBAs are a waste of money. This person did two years of history at Oxford and concluded : in a few weeks of formal study, you can learn enough about economics, finance and strategy. It helps to read about two dozen good books on strategy. (I guess speed reading comes naturally to someone who's doing a PhD in history at Oxford😊)
4. No jerks. Ever. Would colleagues want to sit next to you on a long flight? (the "flight test"). Bascially : follow the no a$$hole rule!
5. Everything's a grid. As in - important/urgent risk/reward pain/gain. 
6. The basics matter - agenda before meeting, lead time planning for next day, minutes and next-steps!
7. Start at the end and go backwards. State the hypothesis and look for evidence the supports/contradicts.
8. Don't look to consultants to save your company. They can only offer recommendations.
9. Everyone is in sales - like it or not. 
10. Manage upwards - handy for the case that your company doesn't follow rule 4 😊 Example : DD works for "the Rottweiler" who works his team to death. Predecessors who burnt out focused on mastering work-work while DD mastered meta-work - in this case, he figured out the office phone-system so he figured out a way to let the Rottweiler's calls go to voicemail. He'd listen to the message at his leisure, do the bare minimum and then use the phone system to record a message to his boss to be delivered later - at 10:30 at night! The Rottweiler was actually telling DD that he was working too hard!

BTW, Brett Arends is the guy who claimed he was going to invest in Russian stocks back in 2014. How did that play out?

If You're On Android, this is How Your Brain Works! Be Warned

From Michael Platt's excellent book: "The Leader's Brain"

Two years ago, Wharton neuroscience postdoctoral fellow Feng Sheng and I gathered groups of smartphone users to see if they had an emotional and social connection with their brand. 

(they used fMRI to observe brain activity)

Apple users showed empathy for their own brand: The reward-related areas of the brain were activated by good news about Apple, and the pain and negative feeling parts of the brain were activated by bad news, they were neutral about any kind of Samsung news. This is exactly what we see when people empathize with other people—particularly their family and friends—but don't feel the joy and pain of people they don’t know.

Samsung users, on the other hand, showed no increased activity in either area when they were shown positive and negative news about their brand. Interestingly, though, the pain areas were activated by good news about Apple, and the reward areas were activated by bad news about the rival company — some serious schadenfreude, or “reverse empathy.”

If I were the Chief Marketing Officer of Samsung, I would be worried. Samsung customers' brains tell us they’re just not that socially and emotionally connected to the brand, and that makes the company much more vulnerable to a potential competitor (just as a weak workplace culture can lead to higher turnover). 

How You Can Promote Neuroplasticity in Your Brain

From positivepsychology.com

1. Intermittent fasting (as noted earlier): increases synaptic adaptation, promotes neuron growth, improve overall cognitive function, and decreases the risk of neurodegenerative disease;
2. Traveling: exposes your brain to novel stimuli and new environments, opening up new pathways and activity in the brain;
3. Using mnemonic devices: memory training can enhance connectivity in the prefrontal parietal network and prevent some age-related memory loss;
4. Learning a musical instrument: may increase connectivity between brain regions and help form new neural networks;
5. Non-dominant hand exercises: can form new neural pathways and strengthen the connectivity between neurons;
6. Reading fiction: increases and enhances connectivity in the brain;
7. Expanding your vocabulary: activates the visual and auditory processes as well as memory processing;
8. Creating artwork: enhances the connectivity of the brain at rest (the “default mode network” or DMN), which can boost introspection, memory, empathy, attention, and focus (see art therapy activities);
9. Dancing: reduces the risk of Alzheimer’s and increases neural connectivity;
10. Sleeping: encourages learning retention through the growth of the dendritic spines that act as connections between neurons and help transfer information across cells

The Navalmanack - Your Most Precious Resource

Naval's recommended reading ("Read what you love till you love to read"): https://www.navalmanack.com/navals-recommended-reading

From one of his favorites, https://meltingasphalt.com/crony-beliefs/

Consider the case of Acme Corp., a property development firm in a small town called Nepotsville. The unwritten rule of doing business in Nepotsville is that companies are expected to hire the city council's friends and family members. Companies that make these strategic hires end up getting their permits approved and winning contracts from the city. Meanwhile, companies that "refuse to play ball" find themselves getting sued, smeared in the local papers, and shut out of new business.

In this environment, Acme faces two kinds of incentives, one ..

If you tried reading that bit, you'll wish Kevin Simler (author of Melting Asphalt and also "The Elephant in the Brain") had read this by Scott Adams:

Business writing is about clarity and persuasion. The main technique is keeping things simple. Simple writing is persuasive. A good argument in five sentences will sway more people than a brilliant argument in a hundred sentences. Don’t fight it.

How You Can Squeeze Notebook LM

It claims to be happy with a URL. Try it and you find it doesn't do much - in fact, nothing at all..

So, what *can* you do?

Download the website - say it's one of those ancient online books with a TOC and Previous/Next buttons on each page. Use httrack.

Then, use this script (click to select) to (since Notebook LM takes markdown) pull the text from each page *meaningfully*. That is, you're saying Notebook LM is smart enough to make something out of headings. Else, you could just give it text. Ja? :)

Yes, you might need to ask chatGPT for a bash script to put all the text files into one - since N LM says something about a 50 file limit.

        output_file = output_arg

And then:
$ for fil in download_folder_name/www.websitename.com/somefolder/text/*.html ;

Then, just upload the files from this destination directory and you're ready to start chatting with your data. It does work!
