-24.0000 ħ (10.0 HOUR) (+0.0)Improved the feeds summary a bit.
-1.0000 ħ (1.0 HUR) (+0.0)To increase the signal-to-noise ratio for first-time visitors of the home page, I have hidden menus, and compacted operations, so as to let the eyes focus on content.
However, apparently, some people didn't like it, because it is not clear what to do, so, I mostly reverted the change.
-10.0000 ħ (10.0 HUR) (+0.0)It is now possible to lock targets, create teasers for investment, and share them with potential interested parties.
-24.0000 ħ (10.0 HOUR) (+0.0)I implemented a hash that takes previous data and current column and the previous hash to produce a hash of the entire database.
This allows us to synchronize with the minimum of data transmissions when I write the synchronizer part which shall rehash all its own data, then retrieve the hash of a binary search of the sorted data.

日の丸月へ行く : 日本の月探査 2029年、トヨタ自動車と宇宙航空研究開発機構（JAXA）などが開発する日本の探査車「ルナ・クルーザー」が宇宙飛行士を乗せて月面を走ろうとしている。曲速引擎 : 超光速旅行的各种设想中，曲速引擎(Warp drive)广为人知 维基百科：曲速引擎（Warp drive）是一种理论上的超光速（faster-than-light, FTL）飞船推进系统，常出现于科幻剧集《星际迷航》（Star Trek）、阿西莫夫的作品中。虽然这个概念来自比Star Trek更早的科幻小说，科学家却认真研究过其可能性。物理学家Miguel Alcubierre提出了一种理论上的解决方案，被称为阿库别瑞引擎或阿库别瑞度规（Alcubierre metric）。 在Alcubierre的论文“曲速引擎：广义相对论中的超高速旅行”中，描述了如何在广义相对论的框架内且不引入虫洞的情况下，以修改时空的方式允许飞船进行超光速航行。方法是在弯曲空间的“气泡”中运输一定数量的平面空间，由其后的时空局部扩展以及其前方的时空收缩而向前驱动，则飞船的运动可能会比受干扰区域外的观察者看到的光速快，而在气泡内的飞船并没有超光速运动，它只是被空间带着行进。 但是需要异常物质(exotic matter)（负能量？）才能扭曲时空。科学家一度认为需要行星级别的能量才能做到。不过后续研究一直在进行，例如这个对阿库别瑞引擎模型的修正。NASA也在研究曲速引擎技术（论文：曲速场力学101）。这篇论文基于共形引力而不是标准广义相对论，对经典阿库别瑞度规进行了分析，认为在共形引力的情况下，阿库别瑞度规不违反弱能量条件，特别是最终的曲速引擎不需要使用异常物质。这个解决方案优化阿库别瑞度规，将负能量需求降低两个数量级。 此外我还发现了两个致力于超高速星际旅行的网站：tauzero.aero和limitlessspace.org。2月火星探测月 : 有三个火星探测器(希望号、天问1号、毅力号)即将到达火星。 阿拉伯联合酋长国的希望号空间探测器已经接近火星，预计在2月9号减速然后滑入环绕火星的轨道。希望号将研究火星低层大气层中的天气事件（例如沙尘暴）以及行星上不同区域的天气变化。 中国的天问1号（因为中文内容比英文内容更少，所以链接了英语维基）将于2月10日进入火星轨道，预计5月份释放携带漫游车的着陆器在火星北半球的乌托邦平原登陆。在这里可以追踪天问1号的轨道。 美国航空航天局（NASA）的毅力号（Perseverance）漫游车将于2月18日降落在火星北半球的杰泽罗陨石坑。杰泽罗陨石坑是位于伊希地平原的一个古代的陨石撞击坑，现有的探测表明那里有古代河流流入伊希地平原形成的现已干涸的三角洲。毅力号的主要任务是寻找那里古代微生物生命的痕迹。
