According to the NASA press service, Barry Wilmore will become the commander during the first manned tests. Together with him, Sunita Williams will go into orbit, she will get the role of a pilot. Mike Fink has been assigned as the reserve member of the mission. If necessary, he will be able to replace any of the main crew members.

Currently, specialists are checking and debugging all systems, the date of the upcoming flight will be determined by the end of July. As expected, after launching from the Cape Canaveral cosmodrome (Florida) and docking with the ISS, the astronauts will spend about two weeks at the orbital station, and then return back to Earth. If the manned flight is successful, the astronauts will be delivered to the ISS by Boeing and SpaceX in turn.

The mass of Starliner, designed for a crew of seven and an autonomous flight lasting 60 hours, is 13 tons. It was first launched unmanned to the ISS on December 20, 2019 from Cape Canaveral Air Force Base. The docking with the orbital complex was planned for December 22, but due to technical problems it was canceled. In May, the second test flight took place, which, despite the problems that arose during the mission, ended in success.

Earlier renders that appeared on the Web hinted at a removable back cover, but now the instruction manual has become available, where this is confirmed.

Slots for SIM cards will be located in the old fashioned way under a removable cover. To install or remove cards, you will need to remove the battery.

Compiled a rating of all devices on Apple Silicon and

The other day, new Apple PCs based on the SoC M2 went on sale. The source decided to compare all the current computers of the company on different platforms of the Apple Silicon family, and at the same time add new iPads and several generations of iPhone to the comparison.

The comparison here is based on Geekbench data, which is not as interesting as using any applications for real tasks, but still it is very interesting to look at the rating in this form.

This rating is generally quite predictable, but for some the results may be quite unexpected. For example, in one of the tests, the iPad Pro on the M1 turns out to be faster than full-fledged Macs on the SoC M1 cut down on the GPU. Since this is a graphics performance test, it actually makes sense.

It will also be useful to clearly see how the M2 in the processor test is not very far behind the M1 Pro with an eight-core CPU.

But the gap between any of the M1 versions and the A15 Bionic is always very large, which is explained not only by the difference in configuration, but also by completely different power limits.

“Ordinary bicycle arithmetic: 0.5 x 2 = 1 wheel.” American inventor built a “math bike”

Ordinary bicycle arithmetic 05 x 2 1 wheel American

An American engineer-inventor, credited on YouTube as “The Q” (possibly a reference to the James Bond character who led the Q department and supplied “Agent 007” with useful spy stuff) posted a video in which he showed the creation of a “math bicycle “. According to legend, the author broke a wheel during another bike ride, and at that moment he came up with the idea of ​​​​creating a bicycle with two halves of wheels instead of one whole. Actually, the formula according to which the construction was carried out is included in the title of the video: 0.5 x 2 = 1 wheel.

I must say, the “math wheel” looks both unusual and spectacular at the same time. Judging by the video, it is quite possible to ride it, and not only on a flat road. Instead of a chamber in the halves of the rear wheel, a polyethylene pipe is used, attached to the rim with rivets – it certainly will not work.

The video is already being actively discussed on the Web – and even more: the “math bike” has become a meme. Its image is used by programmers and engineers to denote spectacular, but generally meaningless things and solutions.
