I don’t know, maybe after five years of living in the USA, this design has grown on me, but darn it, why don’t they make it anymore? The first photo is the GM Futureliner design from way back in 1935. Almost a hundred years old soon!

We see all kinds of houses on wheels. The best, of course, are Airstream – a real dream. They also look vintage.

Last evening, I wondered how difficult it would be to create a program that counts push-ups, pull-ups, jumps, and abdominal exercises, just using the camera of a phone? Naturally, it’s hard to let go of such a thought and simply go to sleep. I quickly sketched something out using OpenCV. The video shows Masha jumping, and in the comments are some randomly selected videos from the internet of push-ups and pull-ups.

Nadezhda Shulga and I try to get acquainted with the local bike trails a couple of times a week. There aren’t that many, and they will run out in a couple of months, forcing us to cycle them again. Today, for example, we rode on the WB&A in Maryland – a trail next to NASA Goddard Space Flight Center, NASA’s largest and oldest laboratory. I want to visit it, but now it’s unclear when it will all open again.

A couple of days before that, we rode around Silver Spring. The second video is from there. A few more days earlier, we spent in Indian Head Rail Trail. A week ago, we were in Percellville. The plan includes another ten or fifteen places, after which we’ll have to start over.

Nevertheless, a bike rack for the tow hitch is a very handy thing. Just load up the bikes, and within an hour or two, you can find trails to suit any taste. True, many are more pedestrian than cycle paths, so you can’t really speed up much on them.

Today there’s a new update on Hybrismart: an analysis of versions and upgrades of SAP Commerce Cloud (aka Hybris) over time.

An example of our local news. A 23-year-old dude was arrested and thrown into a detention center for apparently trying too hard to hit on some lady during a bike ride. She, smartly, sped off home, called the police from there, and provided a description of the scoundrel and his bicycle. Caught him. According to the police, it was his third attempt to draw attention. In short, they locked him up and are calling for other victims to come forward. Likely he’ll get about three years plus end up in a public registry of miscreants so the neighbors know who they are living with.

P.S. I’m not defending the victim here, whoever of the two it might be. Just an example of news you wouldn’t see in Russia.

By the way, here’s a relevant little problem for you.

There are three doctors and one patient. Each of them could be infected with the coronavirus. There are only two pairs of gloves and four masks. The doctors need to perform certain procedures on the patient one by one, for which all doctors need gloves. Masks were put on all four, but there weren’t enough gloves for the three doctors—there are only two pairs. You need to come up with an algorithm where no one will infect anyone else. Not doctors from the patient, not the patient from the doctors, nor the doctors from each other. (In this problem, the coronavirus has mutated, and it infects by contact with hands).

Are there any online games in nature that could be played over the internet family against family, engaging all ages and being interesting? The main feature here is that “team” players do not stare into their gadgets, but rather play with one device taking turns.

Shooters won’t do, I’m talking about family games which require thinking and playing collectively, ideally distributed. Not everyone sitting in a corner and blankly staring at their laptop waiting for their turn, but something displayed on a large TV, laying out fruit, juice, and wine, with both our family and our friends, all playing together?

An example from offline would be the game Pandemic, which we once borrowed from friends to play. It can be played by a group, and theoretically distributed. In it, “all cards are open”, everyone plays for themselves, but everyone either wins or loses together. Discussions, debates occur throughout, and it’s a game that could quite suitably be played through Skype. They’ve adapted it to consoles and tablets, but not to the web with multiplayer functionality.

It seems to me that Pandemic is quite fitting at the moment. It involves saving the world through joint effort.

For games where a player has a hand that shouldn’t be shown to others, personal phones could be used, but there is a risk that participants on each side might just be staring into their screens, which isn’t great.

Walking and shooting, as well as online quests, aren’t very suitable because of optional involvement. Playing all together as a single virtual player in a game like poker doesn’t work for the same reason.

Theoretically it’s like running five clients of an online game on one computer and switching between them as turns pass. Another family runs three clients. In the end, for the game server, there are seven players, but the fact that they use only two computers is a minor detail. But here’s the complexity, running five copies of an application on one machine is quite difficult. Let’s say, one opened in Chrome, another in Chrome’s Incognito mode, a third in Firefox, the fourth in its incognito mode, and the fifth in Safari. And spread these out across five screens. Register each under a personal account for each player. And switch between them using Ctrl-left-right. The other family does the same. But this is a very complicated scheme, just preparing for the game will take half an hour.

Let’s start collecting links – in this era of self-isolation, such things should somehow replace communication.
