🌤 شبیه‌سازی انتشار قطرکهایی که در «صحبت کردن معمولی» ضمن راه رفتن از دهان اشخاصِ 🚨«بدون ماسک» خارج می‌شوند با ابرکامپیوتر فوگاکو در ژاپن نشان داده که یک ناقل که در حال راه رفتن است 🚨🚨تا دو - سه متر پشت سرش قطرکهای حاوی ویروس وجود دارد یعنی فاصلۀ فیزیکی در این حالت از حالتی که اشخاص ایستاده‌اند (۲ متر) باید بیشتر باشد. این حالت شامل ایستادن پشت سر اشخاص در پله برقی هم می‌شود!
و حالت مشابه با فاصلۀ بیشتر، شامل قرار گرفتن پشت سر کسی که در حال دویدن است!
🚨 این اطلاعات نشان می‌دهد که اشخاصی که ماسک نمی‌زنند تا چه حد ممکن است برای دیگران خطرآفرین باشند.

If you initiate a Secret Chat, however, then these communications are end-to-end encrypted and are tied to the device you are using. That means it’s less convenient to access them across multiple platforms, but you are at far less risk of snooping. Back in the day, Secret Chats received some praise from the EFF, but the fact that its standard system isn’t as secure earned it some criticism. If you’re looking for something that is considered more reliable by privacy advocates, then Signal is the EFF’s preferred platform, although that too is not without some caveats. Right now the digital security needs of Russians and Ukrainians are very different, and they lead to very different caveats about how to mitigate the risks associated with using Telegram. For Ukrainians in Ukraine, whose physical safety is at risk because they are in a war zone, digital security is probably not their highest priority. They may value access to news and communication with their loved ones over making sure that all of their communications are encrypted in such a manner that they are indecipherable to Telegram, its employees, or governments with court orders. Emerson Brooking, a disinformation expert at the Atlantic Council's Digital Forensic Research Lab, said: "Back in the Wild West period of content moderation, like 2014 or 2015, maybe they could have gotten away with it, but it stands in marked contrast with how other companies run themselves today." Channels are not fully encrypted, end-to-end. All communications on a Telegram channel can be seen by anyone on the channel and are also visible to Telegram. Telegram may be asked by a government to hand over the communications from a channel. Telegram has a history of standing up to Russian government requests for data, but how comfortable you are relying on that history to predict future behavior is up to you. Because Telegram has this data, it may also be stolen by hackers or leaked by an internal employee. But Kliuchnikov, the Ukranian now in France, said he will use Signal or WhatsApp for sensitive conversations, but questions around privacy on Telegram do not give him pause when it comes to sharing information about the war.
