+

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"

+ (-SPIRV) -Sparc -SystemZ -VE -WebAssembly -XCore" 241 KiB

1. CentOS

+
+

+CentOS 安装时可选不同的配置

+CentOS-Stream 8 为例, 定义软件组的文件是 comps.xml

+HUGE and not fully fonctionall

+
+
+

+

+all-in-one solution, matrix support is not good: cannot show picture

+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。）

+

1. Solution

+
+
+
+

1.1. iBus

+
+
+
+

1.1.1. reddit: ibus on swaywm

+
+

+emacs pyim

+
+
+
+
+

1.2. Emacs transparent, terminal blur

+
+

+sway can't, probably wayfire?

+
+
+
+

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

+
+
+
+

1.6. cursor theme not working

+
+

+ from this issue

+add seat seat0 xcursor_theme Oxygen_White in sway config file

+
+
+
+

1.7. touchpad gesture like gnome

+
+

+use libinput-gestures

+
+
+

1.7.1. issue #1514: touchpad gestures to switch workspaces

+
+
+
  1. pull #4952

    1. pull #6778

    3. +
+
+
+

1.8. notify-send don't work

+
+

+mako, a notification daemon

+
+
+
+

1.9. TODO Wayfire crashes when closing foot terminal

+
+
+

1.10. emacs tool-bar not working(cannot toggle and icon theme missing)

+
+
+
+

1.10.1. cannot toggle: disable custon default-frame-alist, or just use floating mode

+
+
+

1.10.2. TODO icon theme missing: ?

+
+
+
+

1.11. Option –create on workspace prev_on_output|next_on_output?

+
+

+this feature is not compatible with i3, so sway didn't accept the pr

+
+
+

1.11.1. shell script solution

+
+
+

1.11.2. rust, probably useful

+
+
+
+ + +
+

2. Ref

+

+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.

+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.
