I can’t help but share, it’s not just a program, it’s a masterpiece! ) It allows you to emulate electronic circuits, but everything is done so simply and quickly, I’m totally hooked:) It costs 15 bucks, and I think I’ll soon part with them)

Hooray, I assembled my first amplifier) thanks to Dmitri Dmitrienko for valuable advice. The tone signal from 3.42..4.79V at the input (from the player) is amplified to 0..5V at the output. Now figuring out why

I periodically encounter such parking lot markings. And not near expensive hotels where valet parking service is available, but across from shopping centers, similar to the one mentioned

I’m thrilled: it’s like I’m back 20 years ago, studying all this in university. Look, I got the transistor to work. If I had said something like this after my sophomore year in university, they probably would have expelled me on the spot.

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.
