They are currently replacing the screen on my Macbook Pro 16″ (Dec 2020). In the invoice, I see a Lid Angle Sensor listed for replacement. It really surprised me. It turns out that this sensor, which precisely measures the angle of the laptop’s lid, is a recent addition, only found in 16″ Macs. Previously, there was just a standard magnetic field sensor (Hall sensor) for the lid, but now, for some reason, they’ve introduced a more advanced sensor. It leaves one only to guess why. For instance, it could be used in image processing algorithms of the built-in camera. Or maybe it’s for future-proofing, to better integrate FaceID (which, for some reason I don’t understand, is still not included in laptops). Or maybe they just collect usage logs of the lid to better understand the causes of wear issues with various cables and the lid overall.

My phone says I’ve been going up and down a 120-story building for three days straight. I hope my knees will forgive me. Since there was no internet, and I needed something to think about, a question started to bother me.

When climbing stairs, people often push on their thighs with their hands, pressing against the thigh of the leading leg as they step onto the next stair. Why does this work? From a physics perspective, there seems to be no point in doing it. Yet, it somehow makes the climb feel easier. I can’t understand why. The only hypothesis is the shift of the center of gravity slightly forward, but then pressing on the thighs really shouldn’t be necessary, yet everyone does it.

Any ideas?

The main difference between all (10-15) international projects where I have worked over the last six years and 10-15 companies in Russia before that is that there has never been a visible public or personal conflict in the work environment. Of course, people are people, and everyone has their quirks and reasons to annoy others, but there is also a culture where it’s not considered proper to air such grievances outside of the immediate participants. This approach sometimes creates its own problems. For instance, an incompetent specialist or manager may remain in a project for a long time, and everyone simply endures it, leading to decreased productivity. Or they simply do not consider it their problem. As a result, a project planned for one year in Russia often takes two, whereas here it’s planned for two but takes three.

Overall, displaying negative emotions in the presence of those not involved is seen as a weakness of a manager or a specialist. If you think that employee B is messing up, it’s better to help rather than point out how bad employee B is. Whether you help quietly or publicly is a matter of self-promotion; for the outcome, it doesn’t matter. Besides the obvious benefits to the project or company, this employee B will grow and not forget (like in the joke about Pavlov, who was bitten by a dog, grew up, and forgot, but Pavlov grew up and didn’t forget).

Of course, not every project and not every company is like this. My experience simply cannot compare with the collective experience of the readers of this post. But 10-15 projects (=companies), into which I was thrown in various roles, seem sufficient for preliminary conclusions. In Russia, it is normal to point out flaws in the work of a person from a neighboring department, in the work where you are nobody, and he may be young and inexperienced, but a specialist. In Russia, it is normal to personalize criticism, attacking the person, not the quality of their work. This is not only in Russia but almost in any Asian country on local projects. This is such an observation.

Phew, I binge-watched the entire season of Squid Game. For me, it’s the best series lately. Kudos to the Koreans! The survival game idea has been exploited many times before (Cube, The Platform, The Hunger Games) but the series format really hit the spot here.

I once had a startup idea for a business messenger where sellers would subscribe to keywords and topics, and buyers could find sellers and request information. The information request went through pop-up forms with auto-fill based on previously entered form field values.

Interestingly, the concept of forms integrated within messengers has not yet appeared in the market. Could it really be inconvenient? Entering phone numbers, addresses, full names, car VINs, selecting times in a calendar, choosing from multiple offices on a map, passport details for tickets, and all such things.

I think the main barrier is the reluctance to deal with storing sensitive tagged data and the large number of older version messenger clients in users’ hands, where such forms would not be fully supported.

What about supporting old versions? Technically, one could replace forms with a bot that would simply ask questions sequentially, and a seller would just wait until the bot has processed everything. And this is just for old versions. In the new version, there would be a convenient pop-up form.
