一 | Ukrainian President Volodymyr Zelenskyy announced Sunday that he has decided to replace Defense Minister Oleksiy Reznikov with politician Rustem Umyerov. Reznikov "went through more than 550 days of full-scale war. I believe that the Ministry needs new approaches and other formats of interaction both with the military and with society as a whole," Zelenskyy wrote on Telegram.Zelenskyy said that he expects Ukraine's parliament to approve the decision this week, given the voting body's familiarity with Umyerov. He did not elaborate upon his reasons for the replacement. The decision came less than a month after Zelenskyy fired officials in charge of military conscription across each region of the country, citing corruption allegations that he said could amount to treason."This system should be run by people who know exactly what war is and why cynicism and bribery at a time of war is high treason," he wrote on social media at the time.

这种自制便携电脑在创客圈被称为赛博甲板(Cyberdeck),近年来越来越火。 它的形态五花八门,有人用公文包、木盒装,还有人塞进老式口袋电脑甚至锡罐里,树莓派自己选了一个鹈鹕风格的坚固防护箱,防风雨、耐造还好带。 官方示例的配置包括一台树莓派5、一块7英寸触摸屏、蓝牙键盘、扬声器、USB音频系统、电池,以及128GB闪存盘和一颗RTC电池(用于关机后保持时钟运行)。

按照官方说法,任何一台赛博甲板都由四部分组成:电脑本身、外围设备、电源系统和机箱。树莓派建议用单板计算机方案,功耗比传统PC平台低得多,存储可以从SD卡一路扩展到M.2 NVMe固态硬盘。 想折腾的话还能加屏幕、LED灯、传感器甚至软件定义无线电,按自己的任务需求定制。 电源是重点,树莓派5在USB接口满载时功耗可达25W,触摸屏全亮度约3W,官方提醒装机前先算清所有组件的总功率再选电池。 动手顺序也有讲究:先测试所有组件,用纸板规划内部布局,再用3D打印或激光切割做支架,过程中可能需要焊接。 完整指南刊登在《树莓派官方杂志》第168期,可免费在线阅读。Current article:http://www.liaoenxingunchuanglou.buzz/1hae/20260826/7517.pptx
