杂记 20130401

  • 之前evince的快捷键乱套了，使用
    rm ~/.config/evince/accels
    复位
  • 定义了变量var又不用的话，gcc会报warning"unused variable"，解法是
    (void)var;
  • VirtualBox中DNS不工作：运行
    VBoxManage modifyvm "VM name" --natdnshostresolver1 on
    Ref 
  • 一个讲c++11右值引用的link：http://thbecker.net/articles/rvalue_references/section_01.html 
  • Linux清除disk cache: 
    sudo sh -c 'echo 3 > /proc/sys/vm/drop_caches'
    Ref
  •  遇到错误screen-256color not found需要支持新的终端类型：找一台支持screen-256color的机器执行
    infocmp xterm-256color > screen-256color.ti
    把文件拷贝到目标机器后执行
    tic screen-256color.ti
    Ref
  •  最近从ibus换到了fcitx，起初是由于sogou发布了，不过后来还是卸掉了。anran主题不错。fcitx在firefox中光标跟随有点问题，按官方wiki说法打开preedit后就没事了。
  •  最近在vim里折腾youcompleteme这个补全插件，挺好用。顺便也装了vundle来管理插件，很不错
  •  vim更新.vimrc后想直接应用，执行
    so %

A Rocky Migration: Moving from docker-compose to Podman and gVisor

I've been running a few containers for several years. They were all running under rootless Docker with a single user. Initially, I planned to  migrate the containers to VMs , but I couldn't get a stable workflow after about two months of effort. Later,  gVisor caught my attention , and I decided to migrate to Podman with gVisor instead. The new plan is to run each container with  --userns=auto  and use Quadlet for systemd integration. This approach provides better isolation and makes writing firewall rules easier. I'm now close to migrating all my containers. Here are a couple of rough edges I'd like to share. Network Layout I compared  various networking options  and spent a few hours trying the one-interface-per-group approach before giving up. I settled on a single macvlan network and decided to use static IP addresses for my containers. To prevent a randomly assigned IP address from conflicting with a predefined one, I allocated a large IP range for my ...

GameConqueror 0.09 -- Linux Game Hacking Tool

If you are a game hacker If you've been looking for a `CheatEngine for Linux` Then you can't miss this. ============================================== GameConqueror is a game hacking tool for linux, it's written in PyGTK and uses scanmem as its backend. It's supposed to be with most useful features of CheatEngine for Linux. Currently, I've implemented almost everything about scanning, involving variant data types and scan types: Data Types: int{8/16/32/64}, float{32/64}, unknown type(int or float) and unknown width(will try each of them), byte array and string Scan Types: equal, greater, less, changed, unchanged, increased(by), decreased(by) This should be enough for most cases, so I decided to release it at the current status. ============================================= Here's how you can get it PPA (for Ubuntu users) https://launchpad.net/~coolwanglu/+archive/scanmem (I've not test it in 32bit environments or Jaunty, do please inform me if it doe...

Fix Google Security Code

Google Security Code (http://g.co/sc) is one type of 2-step verification. This is particularly useful when security keys and passkeys are not available. I have been using it in my LXC containers, until today I found out that it stopped working. It just kept saying "The code is invalid". It is easy to rule out some factors: The code works on other browsers on my laptop. The code works on other devices that are directly connected to the router. So it appears that Google also checks IP addresses besides the security code. Recently I have IPv6 enabled, so most devices that are directly connected to the router have both IPv4 and IPv6 addresses. But  I only enabled IPv4 for my LXC containers. So I guess when a code is generated by device A and used by device B, Google should be able to check that device A and device B are closely located. But in my case, IPv6 address appears on device A but not on device B, which may look suspicious. To fix the problem, I just needed to disable IPv...
