Just spent half an hour driving a Tesla 100D.

The experience was certainly pleasant, but overall the wow factor came only from the autopilot and auto-parking. The rest is pretty much the same as a similar class BMW or Audi. I didn’t try the sport mode, there would definitely be another wow factor there, but I am a calm driver: over two years I never sped up over 120 km/h because there was no need.

The autopilot is very pleasant. The car maintains a distance by itself, stays in the lane, and gives warnings.

To own a Tesla, you need your own house. Charging from city outlets is not an option at all, incredibly slow. There are no Superchargers in our area yet because all the buyers have homes, and that’s sufficient.

We’ll wait for Model 3 and the infrastructure. They say the third one is much simpler.

Regarding how LinkedIn works. I get about 2500 people a day coming to my blog. 82% of them come from Google (search, “organic”), 10% – from LinkedIn (my own and others’ posts). The other channels, like Facebook or links on the net, are close to zero in share.

I predict that in the very near future, bots will be used in email communications of the type company dash million customers. When a customer receives a special offer, they can ask a follow-up question. The entire dialogue with them is conducted by the system, with a little help from the contact center.

Lisa brought a Yearbook from school. This school issues such a 300-page album every year, incorporating all the past events in photos and facts. Here is Lisa on the Sophomore page. Here the parents bought an ad at the end to thank the kids for finishing school.

Surely, something similar exists in Russian schools too, but in the States, it’s a well-established tradition by the school, whereas in Russia, photographers earn extra by finding their way into the principal’s office before the end of the year, and the school usually doesn’t care much.

Lisa has been buried in that book for an hour now)

Bought and assembled an oscilloscope. For experiments. The kit costs thirty bucks

I always thought that when you shake a bottle of cola or champagne, the pressure inside the bottle doesn’t change at all. I just stumbled upon an argument and delved into the details. It turned out to be almost true. The “explosion” occurs due to the sudden expansion and surfacing of bubbles. When shaken, the carbon dioxide bubbles are submerged in water, and when the bottle is opened, they suddenly increase in size and surface (since there is a pressure difference) pushing some cola or champagne outside. Shaken cola or champagne sinks some of it to the bottom, causing them to rush to the surface too much upon opening, leading to unusually strong foaming. When you shake champagne, these bubbles are not visible because they are too small (the gas dissolved in the liquid occupies less volume), plus a small portion of carbon dioxide under pressure turns into a liquid state. But there are several interesting points. To avoid overloading the post – those interested are directed to the “Conclusions” section of the article linked, and for the especially curious, the article itself is quite intriguing.

This weekend – an important and, I hope, interesting update on my blog about SAP Hybris:

A detailed comparison of Oracle Commerce (ex-ATG) with SAP Hybris Commerce, including Endeca and technical aspects, both On-Premise and cloud versions.

Such a comparison has never been done anywhere on the web before. I tried to be objective in all aspects.

The article is huge, sorry, no conclusions will be drawn 🙂

It takes five minutes to heat water from 20 to 100 degrees. But for some reason, there’s no device capable of cooling a can of beer from the same 20 to 5 degrees (just 15 degrees down) faster than 40 minutes (in the freezer). What kind of injustice is this? By the way, physicists, please explain why. If possible – such a device needs to be released urgently.

I am going to watch the last episode of the first season of Handmaid’s Tale. Such an awesome series.

It’s fascinating how precisely our speech apparatus works and how the brain recognizes sounds. Take, for example, the syllables “па” and “ба.”

The difference between “па” and “ба” is merely in the timing of the sound delay before the vowel: if the delay is longer, we hear “п”, if shorter – “б”. Place your hand on your throat near the vocal cords: when saying “ба,” the lips part simultaneously with the vibration of the cords; when saying “па,” the vibration is delayed.

The graph shows that the difference is generated in the region of 20-30 ms delay

I wonder why various Amazons aren’t interested in customers’ hobbies and interests directly, but try to deduce these only through activity analysis? After all, you could simply ask.

For example, why can’t I input my interests and receive special offers if they align with those interests? It’s very simple and beneficial for everyone, isn’t it?

Of course, few online shop users would bother to specify these in their profile. But you could unobtrusively ask during interactions with the website and enrich the profile with the information obtained.

Also, there’s a lack of a guide for product groups. If I were Amazon, I would consider buying such guides (as a service) from third-party suppliers.
