FB 最近的 ConvNeXt 看起来满强的，实验结果能打 ViT/SwinTransfomer，纯ConvNet 结构，在 MLP-Mixer 之后我越来越觉得在经历一段军备竞赛之后终于回到似乎是回到对结构探索的正确道路上。从算力有限时代的 MLP 到快速又符合直觉的ConvNet滤波计算，出现瓶颈并拥有更多的算力后再去看曾经的结构总是有不一样的启发。不知道下一次能看到像 ResNet 一样留下普世启发的结构是什么时候。https://github.com/facebookresearch/ConvNeXt

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
The super secure UAE-based Telegram messenger service, developed by Russian-born software icon Pavel Durov, is looking to raise $1bn through a bond placement to a limited number of investors from Russia, Europe, Asia and the Middle East, the Kommersant daily reported citing unnamed sources on February 18, 2021.The issue reportedly comprises exchange bonds that could be converted into equity in the messaging service that is currently 100% owned by Durov and his brother Nikolai.Kommersant reports that the price of the conversion would be at a 10% discount to a potential IPO should it happen within five years.The minimum bond placement is said to be set at $50mn, but could be lowered to $10mn. Five-year bonds could carry an annual coupon of 7-8%.
