⭕️ سفر به مرکز زمین این‌بار نه با ژول‌‌وِرن!

🔹️تونل عمودیِ پروژۀ اومااویا به عمق ۶۱۸ متر معادل ۱.۵ برابر ارتفاع برج میلاد در عمق زمین حفر شده، امروز در سریلانکا به بهره‌برداری رسید.
🔹️برای حفاظت از این تونل عمودی، یک غلاف فلزی مشابه لوله به وزن ۱۰۰۰ تن به‌صورت معلق کار شد و از طرفی جریان آب سنگین به داخل شفت هم کار حفاری را پیچیده کرد.
🔹️سال ۲۰۱۰، دو شرکت ایتالیایی پس از اطلاع از جزئیات پروژه از انجام آن انصراف دادند اما این پروژه توسط مهندسان ایرانی ساخته و صبح امروز افتتاح شد.

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 Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
