In December 2020, IBM Research and Fujifilm presented a prototype of the LTO cartridge for 580 terabytes ... A small cassette with a magnetic tape holds information like several dozen ordinary HDDs or 120,000 DVDs.

Magnetic tapes appeared almost a century ago, and computer files have been recorded on them since 1952. Our mothers in Soviet research institutes also changed mainframe coils. And in 2021, tapes remain the cheapest drive, with storage costs about 6 times lower than HDDs. Since film has practically disappeared from the consumer market, many people don't even know how rapidly this technology is developing.

... According to statistics, 100% of the population of Mars are robots.

In recent days, only the lazy has not watched reports on the Perseverance rover (Perseverance, emphasis on the last "e"). On the Internet, you can even listen to the wind of the red planet, it barely breaks through the buzzer of the rover's mechanical joints.

Today we will change the focus a little and talk about more mundane things. What technologies enable the rover to work? How are cloud companies involved in space exploration? And in general - what are the plans of mankind for the Martian lands in the framework of an ambitious mission.
Cloud computing helps the rover stay on track
Amazon Web Services (AWS) recently talked about the role cloud computing plays in processing data from Perseverance.

During the entire mission, NASA is going to store and process arrays of information coming from Mars in the AWS cloud. For a moment, every day the rover sends a record number of photos, audio and video recordings.

Surely, you paid attention to the computer using which the young John Connor hacked PIN-code to the ATM and the access code to the lab in Terminator 2. This computer was the Atari Portfolio. When the movie was showing in theaters in 1991, it seemed beyond the fiction. I was lucky to find it, and I want to share with you its features.

It turned blue, is something wrong with it?

BSOD is the kernel response to an unsolvable particular situation. If you see it, it means that something has happened and it is definitely wrong.

The kernel environment imposes many restrictions on the programmer's free hand: you consider IRQL, sync access to shared variables, and you do not stay too long in ISR, you should verify any data from the userland… Breaking at least one of the rules, you will receive a bunch of phrases in a standard VGA video with the poor palette.

In fact, this makes sense. If in the user mode the application simply closes without even removing a trail after itself (that the kernel will do that), so it will not break the integrity of the entire system.

The article will concern the work of “brains”, which operate the engine of your car or motorbike. I will try to explain as simply as possible and in general, what and how is going on.

What do these “brains” do and what are they for? Electronics is an alternative to other systems performing the same functions. The carburetor used to deal with fuel metering, the ignition used to be operated by the mechanical or vacuum advance measure of the ignition advance. In general it can be realized not by electronics alone and it used to be just this way for quite a long time. On the cars, motorbikes, petrol-powered saws, petrol generators and other places worked and keep working the same systems that are to substitute the injector.
Why was it needed to change anything? Why should the existed, proved and rather reliable system be repealed? It is quite simple – a pursuit of economy, ecology and power. Work accuracy of the written above systems is not enough for the supply of the desired level of ecology and powerfulness, electronic systems of the engine controls began to appear long ago.
