شركة لون تابعة لشركة الفابيت (غوغل) تعلن عن مشروع توفير الإنترنت للمناطق النائية.

يستخدم المشروع مناطيد على ارتفاع 12 الى 18 كم لإنشاء شبكة لاسلكية، وتستخدم المناطيد التيارات الهوائية في الستراتوسفير وبرامج لتغيير ارتفاعها

يحتوي المنطاد على بالونين، يتم ضخ الهيليوم من البالون الرئيسي في البالون الثانوي للصعود، ومن الثانوي للرئيسي للهبوط. كما يتم استخدام الواح الطاقة الشمسية للكهرباء، وفي حال الطوارئ يتم اسقاط وحدة الجهاز التي تزن 15 كجم بمظلة طوارئ، بعد رحلة قد تستغرق 100 يوم.

سيتعين على المستخدمين استخدام هوائيات اتجاهية للارتباط مع المناطيد حتى مسافة 40 كم منه.

Telegram auto-delete message, expiring invites, and more

elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.

Telegram Gives Up On Crypto Blockchain Project

Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”
