这一天终于来了, B站显示 IP 属地

- -

-卸载吧…
-

-
-

1. 我的看法

-
-

-这个事情真正要打击的那些 诈骗/造假/海外势力, 并不会受到影响,
-它们肯定会使用"虚拟专用网络"伪造IP.
-

- -

-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.
-

- -

-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"…
-

- -

-对于普通人, 大多数肯定是没什么影响, 也根本不在意,
-但是有些人, 只想公开自己想让别人看见的,
-那这种平台的强制行为确实会让TA们很不满.

1. CentOS

-
-

-CentOS 安装时可选不同的配置
-

-

-centos_install_config.png
-其实这些就是不同的软件组
-CentOS-Stream 8 为例, 定义软件组的文件是 comps.xml
-左边的基本环境就是 <environment> tag 列表
-一共有11个

-但还是对不上, 应该很接近了…吧?
-

- -

-想起来不联网是没法选择安装软件的
-然后瞅一眼产生的临时文件 /tmp/dnf.cache/

2. Fedora

-
-

-Fedora 分不同的变体, 常见的是 Server 和 Workstation
-与 CentOS 不同, Fedora 是在 kickstarts 定义的变体
-在 [Payload] 中定义了安装哪些软件(组)
-然后根据 comps.xml 就知道安装了什么软件
-

-

发生甚么事了

-
-

-老师上课放(U盘里)视频的时候 "啪" 把U盘拔了!

-下一次插上就提示 "是否格式化" :)

-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: Ventoy 启动盘

-
-
- -
-

咋整

-
-

-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)

-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

- -

-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

-
- -
-

第一次尝试

-
-

-把老师的U盘插上, "嘎嗒"一声熟悉的 gnome 提示音, U盘没显示

-有 /dev/sdc

mount -t 试试? 是不是没文件系统坏了没识别? 不是

fsck 试试? 不行

-嗯??? 似乎有点超出我的知识储备和经验了

-
-
-
-

第二次尝试

-
-

-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

-然后查了一下(当然用英文查), 有没有能修复分区表的? testdisk

-然后先用 dd 整盘备份一下, 跑 testdisk

-很简单就把分区表恢复出来了!

- -

-那就开始拷文件吧…"文件不完整"

-
-
-
-

第三次尝试

-
-

-和 testdisk 一家的软件还有 photorec, 我似乎在 linuxcn 见过(懒得去找链接了)

-这东西一看就知道是通过文件头来识别并恢复文件的

-那就跑呗

-一节课之后, 文件(和曾经被删除的)都回来了

-开心!

-
-
-
- -
- -
-

-我可以比较廉价的进行数据恢复

-联系我后将磁盘镜像传到 FTP 服务器, 不接百度网盘

-暂定价如下:

-
-
-

16GiB 以下 0.3 XMR

-
-
-

16~64GiB 0.5 XMR

-
-
- -
-

后续

-
-

-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

-是不是我连着网给我删了?

-Recently, I would like to test switching from gcc to clang on my Gentoo VM.

warning: you will be crazy to have too many packages can't be build with clang

- -
-

1. problem

-
-

-First I want to make LLVM not targeting too many platform, but changing LLVM_TARGETS don't work

-
- 
[ebuild  N     ] sys-devel/llvm-15.0.3:15::gentoo   USE= "binutils-plugin libffi
- ncurses -debug -doc -exegesis -libedit -test -verify-sig -xar -xml -z3 -zstd"
- LLVM_TARGETS= "(AArch64) (AMDGPU) (ARM) (AVR) (BPF) (Hexagon) (Lanai) (MSP430)
- (Mips) (NVPTX) (PowerPC) (RISCV) (Sparc) (SystemZ) (VE) (WebAssembly) (X86)
- (XCore) (-ARC) (-CSKY) (-DirectX) (-LoongArch) (-M68k) (-SPIRV)" 241 KiB    
-
-
-
-
- -
-

2. and I found [solved] LLVM_TARGETS not respected?(Mar 2022) on gentoo forum

-
-

-It seems that global LLVM_TARGETS setting is not respected,

-and flags such as llvm_targets_AArch64, llvm_targets_ARM, are no longer there.

-They're now forced by default as a precaution.

-
-
- - -
-

3. solution

-
-
-
-

3.1. add something like */* -llvm_targets_AArch64 into /etc/portage/profile/package.use.force

-
-

-I excluded all targets exept for X86, but still 3 left: AMDGPU, BPF, NVPTX

-
-
-
-

3.2. so I also add sys-devel/llvm -llvm_targets_AMDGPU -llvm_targets_BPF -llvm_targets_NVPTX in /etc/portage/package.use/

-
-
-

3.3. and don't forget to add that three excluder to clang or other compiler that uses llvm

-
-
- - -
-

4. finally I got this:

-
-
- 
[ebuild  N     ] sys-devel/llvm-15.0.3:15::gentoo   USE= "binutils-plugin libffi
- ncurses -debug -doc -exegesis -libedit -test -verify-sig -xar -xml -z3 -zstd"
- LLVM_TARGETS= "(X86) -AArch64 -AMDGPU (-ARC) -ARM -AVR -BPF (-CSKY) (-DirectX)
- -Hexagon -Lanai (-LoongArch) (-M68k) -MSP430 -Mips -NVPTX -PowerPC -RISCV

-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。

-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

-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。

-the original post is gone

-您还可以开始执行DNS和WHOIS查找，以找出每次扫描背后的人员。

-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”。

-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。）

-是的，他们把“malicious”拼错了 - 因此它可能不会出现在谷歌搜索“stretchoid and malicious”的结果中。

-
-
-
-

1.4. cannot start sway on lightdm

-
-

-yes, still not stable, and it can't remenber which DE you used last time

so use gdm is a better choice?

-SDDM is fantastic! It is themeable,

-I'm using elarun, a oxygen-like smooth crystal theme, materia-kde is also a good choice

-
-
-
-

1.5. obs

-
-

-don't remove the include line in sway/config

-
-
-
-

1.6. cursor theme not working

-

1.11. Option –create on workspace prev_on_output|next_on_output?

-强烈推荐 everforest 这个主题

-
-

-Everforest is a green based color scheme, it's designed to be warm and soft in order to protect developers' eyes.

-
- -

-是一个绿色系护眼主题, 正如名字, 有森林的气息

-分为暗色和亮色, 每一种都有三种不同深浅的背景

作者是中国人, 制作了许多高质量 Vim 主题

1. emacs

-
-

-这个主题在 2022-06-29 才开始制作 emacs 版本

-目前还没在 melpa 上, 所以需要手动安装

-我一看到这个就从 Nord 换过来了

-我加入了 whitespace-mode 的支持, 默认的颜色太晃眼睛啦

希望大家能一起帮忙贡献这个主题

- -

-放一段 Rust 代码的效果

-卸载吧…

-
-

1. 我的看法

-
-

-这个事情真正要打击的那些 诈骗/造假/海外势力, 并不会受到影响,

-它们肯定会使用"虚拟专用网络"伪造IP.

- -

-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.

- -

-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"…

- -

-对于普通人, 大多数肯定是没什么影响, 也根本不在意,

-但是有些人, 只想公开自己想让别人看见的,

-那这种平台的强制行为确实会让TA们很不满.

-
-

-By making something a little bit more inaccessible, we are inadvertently putting a filter on what is being posted.

-
-
-

-This makes it a great way to avoid a lot of the low effort noise published on popular/accessible platforms.

-As a result, Gopher is full of interesting, enriching, high quality content.

-The authors are posting out of passion, and with great commitment.

-Don't get me wrong, there's nonsense on Gopher too, but far less of it.

Gentoo LLVM_TARGETS not Working?

-

-Recently, I would like to test switching from gcc to clang on my Gentoo VM.
-warning: you will be crazy to have too many packages can't be build with clang
-

- -
-

1. problem

-
-

-First I want to make LLVM not targeting too many platform, but changing LLVM_TARGETS don't work
-

-
-
[ebuild  N     ] sys-devel/llvm-15.0.3:15::gentoo  USE="binutils-plugin libffi
-ncurses -debug -doc -exegesis -libedit -test -verify-sig -xar -xml -z3 -zstd"
-LLVM_TARGETS="(AArch64) (AMDGPU) (ARM) (AVR) (BPF) (Hexagon) (Lanai) (MSP430)
-(Mips) (NVPTX) (PowerPC) (RISCV) (Sparc) (SystemZ) (VE) (WebAssembly) (X86)
-(XCore) (-ARC) (-CSKY) (-DirectX) (-LoongArch) (-M68k) (-SPIRV)" 241 KiB    
-
-
-
-
- -
-

2. and I found [solved] LLVM_TARGETS not respected?(Mar 2022) on gentoo forum

-
-

-It seems that global LLVM_TARGETS setting is not respected,
-and flags such as llvm_targets_AArch64, llvm_targets_ARM, are no longer there.
-They're now forced by default as a precaution.
-

-
-
- - -
-

3. solution

-
-
-
-

3.1. add something like */* -llvm_targets_AArch64 into /etc/portage/profile/package.use.force

-
-

-I excluded all targets exept for X86, but still 3 left: AMDGPU, BPF, NVPTX
-

-
-
-
-

3.2. so I also add sys-devel/llvm -llvm_targets_AMDGPU -llvm_targets_BPF -llvm_targets_NVPTX in /etc/portage/package.use/

-
-
-

3.3. and don't forget to add that three excluder to clang or other compiler that uses llvm

-
-
- - -
-

4. finally I got this:

-
-
-
[ebuild  N     ] sys-devel/llvm-15.0.3:15::gentoo  USE="binutils-plugin libffi
-ncurses -debug -doc -exegesis -libedit -test -verify-sig -xar -xml -z3 -zstd"
-LLVM_TARGETS="(X86) -AArch64 -AMDGPU (-ARC) -ARM -AVR -BPF (-CSKY) (-DirectX)
--Hexagon -Lanai (-LoongArch) (-M68k) -MSP430 -Mips -NVPTX -PowerPC -RISCV
-(-SPIRV) -Sparc -SystemZ -VE -WebAssembly -XCore" 241 KiB

-

-By making something a little bit more inaccessible, we are inadvertently putting a filter on what is being posted.
-

-This makes it a great way to avoid a lot of the low effort noise published on popular/accessible platforms.
-As a result, Gopher is full of interesting, enriching, high quality content.
-The authors are posting out of passion, and with great commitment.
-Don't get me wrong, there's nonsense on Gopher too, but far less of it.

记一次帮老师修U盘

- -
-

发生甚么事了

-
-

-老师上课放(U盘里)视频的时候 "啪" 把U盘拔了!
-下一次插上就提示 "是否格式化" :)
-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: Ventoy 启动盘
-

-
-
- -
-

咋整

-
-

-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)
-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
-

- -

-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
-

-
- -
-

第一次尝试

-
-

-把老师的U盘插上, "嘎嗒"一声熟悉的 gnome 提示音, U盘没显示
-有 /dev/sdc
-mount -t 试试? 是不是没文件系统坏了没识别? 不是
-fsck 试试? 不行
-嗯??? 似乎有点超出我的知识储备和经验了
-

-
-
-
-

第二次尝试

-
-

-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
-然后查了一下(当然用英文查), 有没有能修复分区表的? testdisk
-然后先用 dd 整盘备份一下, 跑 testdisk
-很简单就把分区表恢复出来了!
-

- -

-那就开始拷文件吧…"文件不完整"
-

-
-
-
-

第三次尝试

-
-

-和 testdisk 一家的软件还有 photorec, 我似乎在 linuxcn 见过(懒得去找链接了)
-这东西一看就知道是通过文件头来识别并恢复文件的
-那就跑呗
-一节课之后, 文件(和曾经被删除的)都回来了
-开心!
-

-
-
-
- -
- -
-

-我可以比较廉价的进行数据恢复
-联系我后将磁盘镜像传到 FTP 服务器, 不接百度网盘
-暂定价如下:
-

-
-
-

16GiB 以下 0.3 XMR

-
-
-

16~64GiB 0.5 XMR

-
-
- -
-

后续

-
-

-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
-是不是我连着网给我删了?

1.3. Authorization required, but no authorization protocol specified

-
-
-
-

1.3.1. sudo -E

-
-
-

1.3.2. lxpolkit(directly execute) or polkit-gnome(prettier, at /usr/libexec/polkit-gnome-authentication-agent-1)

-
-
-
-

1.4. cannot start sway on lightdm

-
-

-yes, still not stable, and it can't remenber which DE you used last time
-so use gdm is a better choice?
-SDDM is fantastic! It is themeable,
-I'm using elarun, a oxygen-like smooth crystal theme, materia-kde is also a good choice
-

-
-
-
-

1.5. obs

-

-don't remove the include line in sway/config
-

-
-
-
-

-
-
-

-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。
-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
-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。

-您还可以开始执行DNS和WHOIS查找，以找出每次扫描背后的人员。
-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”。
-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。）
-是的，他们把“malicious”拼错了 - 因此它可能不会出现在谷歌搜索“stretchoid and malicious”的结果中。
