Android OS developers announced the transition to a new format of applications and games in the summer of 2021. The official Google blog warns about replacing the usual software extension APK with AAB.

The Android App Bundle (AAB) was introduced back in 2018 and it is this format that software developers have gradually switched to. The essence of the innovation is that now Google itself is engaged in the optimization of various versions of the application, "packing" them into a container. The user will not be able to manually install the AAB file itself on the smartphone, as was the case with the usual APK files. This will increase the security of applications, but also negatively affect the "openness" of the Android platform.

Google has planned to completely switch its Google Play app store to AAB format in August. It is said that users will benefit in the amount of software that will take 15-20 percent less memory on the device.

Its new president and CEO Yuki Kusumi shared his thoughts on the ways of development of Panasonic corporation with representatives of Bloomberg. His immediate task is to complete the transformation of Panasonic into a holding company in two years and free up billions of US dollars as a result of the abandonment of activities recognized as ineffective. The company will direct these funds to new initiatives, not excluding acquisitions of other companies. Panasonic recently announced its intentions to acquire software developer Blue Yonder for $ 7 billion, the platform of which will allow the Japanese giant to optimize production processes and reduce operating costs.

US intelligence believes Russia is behind the acoustic and directed energy attacks. The Washington Post writes about this with reference to unnamed representatives of the US intelligence community.

The newspaper recalled several cases of acoustic attacks on American diplomats, including incidents in Cuba. "Following reports of similar incidents in China, Russia and even the United States, US intelligence officials now claim that Russia is responsible for attacks that may employ microwaves or other forms of directed energy."

Politico, citing knowledgeable sources, reported that the US authorities suspect that the Russian GRU may be behind the alleged "directed energy" attacks against US diplomats and intelligence officers around the world. At the same time, the publication noted that so far there is no direct evidence of Russia's involvement in these attacks.

directed energy attack is the impact of highly concentrated electromagnetic energy, including the use of powerful radio frequency or microwave devices, as well as particle streams. Results can be very different.

Biggest fun here is that US totally made thing up. As they have only words of few people that they "felt something", no proof, no anything.
It is ideal thing to make accusations that no one have any slightest chance to debunk.
