NASA 关闭航海家的科学设备以节省电力
#NASA

NASA JPL 任务工程师于 2 月 25 日关闭了航海家 1 号上的宇宙射线子系统实验装置,将于 3 月 24 日关闭航海家 2 号上的低能带电粒子仪,希望借此减缓两艘探测器电力消耗的速度。航海家 1 号和 2 号于 1977 年发射,近五十年来持续依靠其放射性同位素动力系统,也就是利用钸衰变的热量产生电力。项目经理表示:如果我们现在不关闭每艘航海家号上的部分仪器,那么它们的电力可能只能维持几个月。这也不是第一次关闭航海家号的部分机能,早在去年十月,科学家们便因为航海家二号上测量等离子体粒子数量及方向的等离子体科学仪器收集的数据有限,而关闭仪器以节省电力。

Export WhatsApp stickers to Telegram on Android

From the Files app, scroll down to Internal storage, and tap on WhatsApp. Once you’re there, go to Media and then WhatsApp Stickers. Don’t be surprised if you find a large number of files in that folder—it holds your personal collection of stickers and every one you’ve ever received. Even the bad ones.Tap the three dots in the top right corner of your screen to Select all. If you want to trim the fat and grab only the best of the best, this is the perfect time to do so: choose the ones you want to export by long-pressing one file to activate selection mode, and then tapping on the rest. Once you’re done, hit the Share button (that “less than”-like symbol at the top of your screen). If you have a big collection—more than 500 stickers, for example—it’s possible that nothing will happen when you tap the Share button. Be patient—your phone’s just struggling with a heavy load.On the menu that pops from the bottom of the screen, choose Telegram, and then select the chat named Saved messages. This is a chat only you can see, and it will serve as your sticker bank. Unlike WhatsApp, Telegram doesn’t store your favorite stickers in a quick-access reservoir right beside the typing field, but you’ll be able to snatch them out of your Saved messages chat and forward them to any of your Telegram contacts. This also means you won’t have a quick way to save incoming stickers like you did on WhatsApp, so you’ll have to forward them from one chat to the other.

Newly uncovered hack campaign in Telegram

The campaign, which security firm Check Point has named Rampant Kitten, comprises two main components, one for Windows and the other for Android. Rampant Kitten’s objective is to steal Telegram messages, passwords, and two-factor authentication codes sent by SMS and then also take screenshots and record sounds within earshot of an infected phone, the researchers said in a post published on Friday.
