<title>记一次帮老师修U盘</title>
<description><![CDATA[<div id="content" class="content">
<div class="outline-2">
<h2>发生甚么事了</h2>
<div class="outline-text-2">
<p>
老师上课放(U盘里)视频的时候 "啪" 把U盘拔了! <br></br>
下一次插上就提示 "是否格式化" :) <br></br>
反正闲时间太多, 我就准备试试给修复一下, 使用我在我文具盒里待了两年的工具箱: <a href="https://www.ventoy.net">Ventoy</a> 启动盘 <br></br></p>
</div>
</div>
<div class="outline-2">
<h2>咋整</h2>
<div class="outline-text-2">
<p>
我首先是对 Linux 文件系统有一定基础, 也进行过不少操作(如多次安装gentoo和arch) <br></br>
也搞过一些文件系统损坏的事(比如调分区坏过C盘), 还算有经验 <br></br></p>
<p>
于是我上老师电脑启动了两年前放在工具箱盘里的 Fedora Workstation 34 <br></br></p>
</div>
<div class="outline-3">
<h3>第一次尝试</h3>
<div class="outline-text-3">
<p>
把老师的U盘插上, "嘎嗒"一声熟悉的 gnome 提示音, U盘没显示 <br></br>
有 <code>/dev/sdc</code> <br></br> <code>mount -t</code> 试试? 是不是没文件系统坏了没识别? 不是 <br></br> <code>fsck</code> 试试? 不行 <br></br>
嗯??? 似乎有点超出我的知识储备和经验了 <br></br></p>
</div>
</div>
<div class="outline-3">
<h3>第二次尝试</h3>
<div class="outline-text-3">
<p>
只有一个整盘, 没有分区号? 凭直觉, 我觉得那就是分区表坏了 <br></br>
然后查了一下(当然用英文查), 有没有能修复分区表的? <a href="https://www.cgsecurity.org">testdisk</a> <br></br>
然后先用 <code>dd</code> 整盘备份一下, 跑 testdisk <br></br>
很简单就把分区表恢复出来了! <br></br></p>
<p>
那就开始拷文件吧…"文件不完整" <br></br></p>
</div>
</div>
<div class="outline-3">
<h3>第三次尝试</h3>
<div class="outline-text-3">
<p>
和 testdisk 一家的软件还有 <code>photorec</code>, 我似乎在 <a href="https://linux.cn">linuxcn</a> 见过(懒得去找链接了) <br></br>
这东西一看就知道是通过文件头来识别并恢复文件的 <br></br>
那就跑呗 <br></br>
一节课之后, 文件(和曾经被删除的)都回来了 <br></br>
开心! <br></br></p>
</div>
</div>
</div>
<div id="outline-container-ad" class="outline-2">
<h2 id="ad">接活?</h2>
<div class="outline-text-2" id="text-ad">
<p>
我可以比较廉价的进行数据恢复 <br></br>
联系我后将磁盘镜像传到 FTP 服务器, <b>不接百度网盘</b> <br></br>
暂定价如下: <br></br></p>
</div>
<div class="outline-3">
<h3>16GiB 以下 0.3 XMR</h3>
</div>
<div class="outline-3">
<h3>16~64GiB 0.5 XMR</h3>
</div>
</div>
<div class="outline-2">
<h2>后续</h2>
<div class="outline-text-2">
<p>
恢复完之后我想瞅瞅那些教学视频, 正常来讲 f34 应该有解码器的, 但是没有 <br></br>
是不是我连着网给我删了? <br></br></p>

<title>Clear Kernel Build Error? Fix It</title>
<description><![CDATA[<div id="content" class="content">
<p>
when I compile <a href="https://github.com/gentoobr/overlay/tree/master/sys-kernel/clear-sources">Clear</a> kernel with LLVM enabled, I got this error: <br></br></p>

<title>Gentoo LLVM_TARGETS not Working?</title>

It seems that global <code>LLVM_TARGETS</code> setting is not respected, <br></br>

They're now forced by default as a precaution. <br></br></p>

博客主评价，有很多包括stretchoid.com的组织，有的是把自己伪装成科研实验用数据，并没有恶意，有的是什么理由也不给，只是不停地扫描全网的网站。 <br></br>
其中也包括像密歇根大学，加州大学伯克利分校的访问信息。因为网络安全领域没有类似于“希波克拉底誓言”的东西，所以不能像医生一样信任 <br></br>
就像到处晃别人家的门把手而不打开不是犯罪，但是真正的打开就混在发现没有锁门，而晃门把手时。 <br></br></p>

在这个简短的样本中，我找到了一个伪“研究员”：107.170.202.111解析为“zg-0301f-15.stretchoid.com”。 <br></br>
他们没有确定他们正在做什么或为什么他们在161 / udp扫描我的蜜罐。（端口161 / udp是为简单的网络管理协议（SNMP）保留的，并且经常容易受到攻击。） <br></br>

<title>Recommend EverForest Theme</title>
<description><![CDATA[<div id="content" class="content">
<p>
强烈推荐 everforest 这个主题 <br></br></p>

<p>
Everforest is a green based color scheme, it's designed to be warm and soft in order to protect developers' eyes. <br></br></p>
</blockquote>
<p>
是一个绿色系护眼主题, 正如名字, 有森林的气息 <br></br>

这个主题在 2022-06-29 才开始制作 <a href="https://github.com/Theory-of-Everything/everforest-emacs">emacs 版本</a> <br></br>
目前还没在 melpa 上, 所以需要手动安装 <br></br>
我一看到这个就从 <a href="https://github.com/arcticicestudio/nord-emacs">Nord</a> 换过来了 <br></br>
我加入了 whitespace-mode 的支持, <del>默认的颜色太晃眼睛啦</del> <br></br> <b>希望大家能一起帮忙贡献这个主题</b> <br></br></p>

<title>这一天终于来了, B站显示 IP 属地</title>

<h2> <span class="section-number-2">1.</span> 我的看法</h2>
<div class="outline-text-2" id="text-1">
<p>
这个事情真正要打击的那些 <b>诈骗/造假/海外势力</b>, 并不会受到影响, <br></br>
它们肯定会使用"虚拟专用网络"伪造IP. <br></br></p>
<p>
那些所谓的"翻车"博主, 大多数可能只是公司在国内, 却因为这件事被各大媒体揪出来. <br></br></p>
<p>
对于那些网络喷子, 这种事估计不会减少它们的言论, 反而会加重"地域黑"… <br></br></p>
<p>
对于普通人, 大多数肯定是没什么影响, 也根本不在意, <br></br>
但是有些人, 只想公开自己想让别人看见的, <br></br>
那这种平台的强制行为确实会让TA们很不满. <br></br></p>
