Snail uses the Emacs display-buffer system to pop up windows, and tries to do so in the most sane manner possible. Most information pop-ups (except the REPL) can be dismissed by pressing q, and this should restore the window configuration in most cases. With Emacs defaults, Snail should also reuse existing windows as much as possible, i.e., calling julia-snail from a source buffer will switch an already-visible REPL window, and calling julia-snail from a REPL window will switch back to a source buffer and reuse already-visible windows.

“头足类动物能够通过调控皮肤的乳突(皮肤上可伸缩的微小突起)和色素细胞改变自身纹理和颜色,这是它们实现惊人伪装能力的关键。”该论文的共同通讯作者、斯坦福大学博士生西达尔特·多希在接受本报记者采访时表示,研究团队一直希望能在工程材料上复现这一精妙的自然机制。一次偶然的发现让他们找到了突破口。“我们发现,一块曾在扫描电子显微镜下观察过的PEDOT:PSS(一种导电聚合物)样品,其被电子束照射的区域,溶胀行为(指材料接触溶剂时因溶剂分子渗透而发生的膨胀现象)与未照射区域截然不同。受到电子束照射的区域,其结构变得紧致,遇水后的膨胀能力被大大抑制;而未照射的区域则能自由吸水大幅隆起。”多希说。,推荐阅读手游获取更多信息

“I went to The Computer Museum in Boston in 1991, I think it was, and they had the life size models of these robots.” Jackpot! From there it was a piece of cake to track down definitive proof that these were life-size props:
