What XR Should Be in 2023
XR is being brought to the public again after Apple announced their new XR headset, Apple Vision Pro. However, Apple is hesitant about this product as, during WWDC, no one other than those featured in the promotion video was seen wearing it. The reason is obvious: using a computer that covers your face in front of a camera is weird (not to mention that it ..

Read moreLocalhost Issue in WSL2
I was attempting to build a remote debugger for an embedded device when I had no access to a physical device. As a solution, I decided to try using Docker (with the WSL2 backend). In the project’s design, the 9090 UDP port was supposed to be used for communication between the host and the slave. However, it appeared that using ‘localhost’ or ‘127.0.0.1’ di..

Windows 8 and later have a function named “Device Encryption”. It allows Windows to automatically enable BitLocker for local disks and unlock them at startup. However, if you are using a DIY rig or have changed/added some hardware to your OEM machine, this feature might be broken. Therefore, we need to add those devices to the whitelist to re-enable the fe..
Read moreWindows 11 & Forgy
原来还有许多人关注着 Frogy 这个项目。一天有人突然发邮件给我说，他从 0.0.5 更新至 0.0.9 时打开控制台会闪退，于是我又短暂找回了两三个月之前那种热情完成了一次敏捷 debug 。虽然后面马上发现有问题，立刻又被迫发布了一版 0.0.11 。 Windows 11 的 ISO 也在昨晚泄露了。遥想当年，Windows 8 开发者预览版的时候我还是一个不会装系统，用洛克王国官图当壁纸的小孩，熬夜顶着 200 kb/s 的 ADSL 下载了第一个 Windows insider 。然后乐此不疲地解决着 Windows 8 的各种问题，欣然接受开始屏幕，在应用商店发掘有趣的小 app 。也是这个时候知道了 Windows phone 和小娜。 有幸在初三的时候到了人生地不熟的小城市念书，低压的学习..

However, these steps are mostly the same for any other distribution, with the only differences being the package manager and the package names.

很久以前看过一篇文章，讲的是在猫的认知中，所有物种都是自己的“同类”，只不过有体型大小之分。由此不难想到，若一只猫从小跟在人类身边，鉴于野兽按体型决定力量下限的特性，幼猫大概会很想要长得和人那般体型。但可能直到它临终的前一刻才发现——自己大概永远也长不到那么大了。 近来心事繁重，闲来便翻阅一些论坛，看看大家伙平时都在做些什么。偶然撇见一则喂食流浪猫的帖子，想到了之前那篇文章。若猫也会苦于自己无法独立找到吃食而必须等待投喂会是怎样？猫是否会想知道人究竟是从哪里捕来的猎物，为何自己未曾遇到。 但经提醒后，忆起前几日还看过另外一篇文章，讲的是猫相比于捕猎，更喜不劳而获。 想到这里，我大概明白了。或许是我一直从自己身而为人的角度去以己度猫，所谓“快乐可持续化”要么是人类群体组织者的阴谋要么就是人类进化的副作用，或许..

缓冲液内微型机械状态良好，回报率99.93%，随时可以进行脊髓内注射。AI推测这次试验的成功率低于四成，但直觉告诉我应该做下去。 我现在所处的国立国防科技大学的地下研究所，是火星对地球开展无差别核武器轰炸后为数不多的完好设施。辐射使得大量幸存于地下设施的人类丧生，但我却因为先天的自修复染色体基因幸免于难。 虽然有着基因上的先天优势，我依然得为食物发愁。但当我真正在盖格计数器失去读数的废墟发现活生生的兔子的时候，还是下意识地先提取了它的血清。微型机械定向诱发DNA突变，正是我毕生研究的目标。但受限于人类对未知事物的恐惧，曾经的地球政府对这类研究向来谨慎。因而真正的科学，总得需要一块无法无天的地方，才能肆意生长。 要是想在这种恶劣的环境中生存下来……敏捷的行动能力，高速的新陈代谢，视力，嗅觉……动物，动物独有的..
