存储鼠标位置,便于多屏幕/窗口切换

最近研究了下AutoHotKey这个小玩具,跟高中时代玩过的AutoIt很像,不过这边更侧重于全局热键的实现。

前几天也把多年不用的C#重新用了下,四处抄抄代码做了个跟按键精灵类似的东西,突然想到AutoIt这个老物,于是又搜索了下又没有什么更好地方案,毕竟AutoIt印象里体积比较大,而且闭源。

具体对比可以参考 https://ui.vision/blog/ahk-vs-autoit/

工具介绍

这个工具的功能是每按一次热键将鼠标位置保存,并切换到原来位置。

主要用途是简化多屏幕/多窗口远距离频繁移动。

比如debug时有两个窗口,一边是代码,另一边是调试中的程序,在两个屏幕反复移动比较累(懒癌晚期),所以可以用一个快捷键快速切换位置。

捡了个ebaz4205玩玩

今天随便刷了刷手机,发祥fpga也有矿了…然后随手一搜发现好久前就有了,闲鱼上入了两片玩玩

手里的下载器是10pin的,还要买个转接板子,于是说100块的zynq体验之旅开始

接下来等待到货,顺便前几天为了给cuda腾地方,随手又把vivado给删了,这两天还要再安上,我觉得我可能需要一个大号的固态来放/opt

srcnn训练记录

最近打算改造下tachiyomi的图像加载,准备研究下超分辨率,改良一下缩放算法

srcnn

直接用的https://github.com/tegg89/SRCNN-Tensorflow,不过这个库貌似直接把所有图像一次全加载到内存了,所以我就少放了几张图

先测试下srcnn,貌似是最古老的,也比较好理解。最新(2019)的貌似是小米的那个算法

标记一下,预计这周训练够抢能结束o.o

记录下中间过程,训练一个下午(看视频+午觉)的时间,生成的图像还是不太能看的

orugin
srcnn
二次平方插值

现在这个明显发暗,而且高频噪声好多。虽然比插值好些,但是差的有点多(训练一下午,收敛的好慢,要是不如插值直接删代码~~)不过可以通过曲线调节下

调节前
srcnn+gimp曲线
调节后

迭代400次

迭代700次,效果明显好很多,不过由于夜间模式,手动调色可能有偏差

看来默认迭代15000次是有道理的

目标

下面这个是目标(waifu2x,我直接用的bigjpg.com的结果)(测试完srcnn,准备转到这个算法上来)

waifu2x(bigjpg)

闲的没事再看看Fuchsia

首先就是蛋疼的jiri update,最近恰逢网络维护节,因此托代码很难受。

本来想体验下国内镜像的,但我刚打开tg就看见大家在爱国…

下载

依旧去官网参考教程吧…

git config --global https.proxy 'http://127.0.0.1:7777'
git config --global http.proxy 'http://127.0.0.1:7777'
env http_proxy=http://127.0.0.1:7777 ./.jiri_root/bin/jiri update

安装

首先依旧替换系统python到python2

⋊> /s/w/p/f/fuchsia on dd551fb3e4  sudo rm /usr/bin/python
⋊> /s/w/p/f/fuchsia on dd551fb3e4  sudo ln -s /usr/bin/python2 /usr/bin/python 

执行fx set的时候提示数据收集

⋊> /s/w/p/f/fuchsia on dd551fb3e4  ./scripts/fx set core.x64                                                                                                                                                                                                                        07:32:42

看一下fx metrics的说明

When enabled, this tool creates a random unique user ID (UUID) for the Fuchsia
repository and uses that to collect the following anonymized metrics of
the session and user workflow in order to improve the user experience:

1. For every "fx" invocation:
   - The output of "uname -rs" (Kernel name and release)
   - The name of the "fx" subcommand invoked
   - (in the future) Imports in BUILDDIR/args.gn for product and board
   - (in the future) Value FUCHSIA_ARCH from BUILDDIR/fx.config

2. For the following subcomand(s) [set]:
   - All arguments passed to the subcommand

3. (in the future) For the following subcomand(s) [set,build]:
   - Time taken to complete
   - Exit status

When metrics collection is disabled, any existing UUID is deleted, and a
new UUID will be created if metrics is later re-enabled.

When enabled, the UUID and the status are stored in /storage/wine/project/fuchsia/fuchsia/.fx-metrics-config

usage:
 fx metrics
      Show what metrics are collected when enabled

 fx metrics status
      Show if metrics collection is enabled or disabled

 fx metrics [--log=LOG_FILE] enable
      Enable metrics collection in fx tools
      --log=<LOG_FILE>  Log all metrics collected to LOG_FILE for
                     debugging purposes. The LOG_FILE setting is persisted
                     in a config file in the /tmp filesystem and will be
                     reset when the user logs out.

 fx metrics disable
      Disable metrics collection in fx tools

说的挺好的,比某些强制要权限的安卓软件强不少,我就启用了吧

⋊> /s/w/p/f/fuchsia on dd551fb3e4  ./scripts/fx metrics enable                                                                                                                                                                                                                      07:37:04
Collection of metrics is now enabled for /storage/wine/project/fuchsia/fuchsia

重新set一下

⋊> /s/w/p/f/fuchsia on dd551fb3e4  ./scripts/fx set core.x64                                                                                                                                                                                                                        07:37:10
Generating compile_commands took 604ms
Done. Made 25631 targets from 2150 files in 11538ms

于是开始编译fx full-build

⋊> /s/w/p/f/fuchsia on dd551fb3e4  time ./scripts/fx full-build
。。。。。。

好吧,看来编译的脚本改了不少,这命令已经没了,执行fx build,依旧对硬盘要求很大,由于没用固态编译,所以速度还是很慢,link的时候内存上到了10左右(我偶然看到的,没一直看)不足16g内存编译需要swap

⋊> /s/w/p/f/fuchsia on dd551fb3e4  time ./scripts/fx build                                                                                                                                                                                                                          07:40:56

附一张系统状态的图

编译开始的时候系统状态

运行

经过艰难的编译等待(看电影一集),终于要运行了

⋊> /s/w/p/f/fuchsia on 24db8fdf7f ⨯ ./scripts/fx run -m 4096                                                                          09:49:26

emmm,很有意思,怎么又挂了,开始查下坑

./script/fx脚本得知所有像run,build这些命令存放在${fuchsia_dir}/tools/devshell/${cmd},也就是说run命令作为一个脚本放在devshell里面。报错代码位于50行

if [ -n "$IMAGE_FVM_RAW" ]; then
  fvmimg="${imgdir}/fvm.blk"
  args+=(-d -D "${fvmimg}" --diskfmt=raw)
  stat_flags=()
  if [[ $(uname) == "Darwin" ]]; then
    stat_flags+=("-x")
  fi
  stat_output=$(stat "${stat_flags[@]}" "${FUCHSIA_BUILD_DIR}/${IMAGE_FVM_RAW}")
  if [[ "$stat_output" =~ Size:\ ([0-9]+) ]]; then
    size="${BASH_REMATCH[1]}"
    newsize=$(($size * 2))
    # We must take a copy of the build artifact, rather than re-use it, as we
    # need to modify it in order to extend it.
    echo -n "Creating disk image..."
    cp "${FUCHSIA_BUILD_DIR}/${IMAGE_FVM_RAW}" "${fvmimg}"
    "${ZIRCON_TOOLS_DIR}/fvm" "${fvmimg}" extend --length "${newsize}"
    echo "done"
  else
    fx-error "could not extend fvm, unable to stat fvm image"
  fi
fi

为了调试在stat附近添加echo来获得更详细的信息

这样错误原因就很明显了,我的stat是中文输出的,不匹配正则表达式,因此修改正则,看着好怪异

if [ -n "$IMAGE_FVM_RAW" ]; then
  fvmimg="${imgdir}/fvm.blk"
  args+=(-d -D "${fvmimg}" --diskfmt=raw)
  stat_flags=()
  if [[ $(uname) == "Darwin" ]]; then
    stat_flags+=("-x")
  fi
  stat_output=$(stat "${stat_flags[@]}" "${FUCHSIA_BUILD_DIR}/${IMAGE_FVM_RAW}")
  echo stat "${stat_flags[@]}" "${FUCHSIA_BUILD_DIR}/${IMAGE_FVM_RAW}"
  echo $stat_output
  if [[ "$stat_output" =~ 大小:([0-9]+) ]]; then
    size="${BASH_REMATCH[1]}"
    newsize=$(($size * 2))
    # We must take a copy of the build artifact, rather than re-use it, as we
    # need to modify it in order to extend it.
    echo -n "Creating disk image..."
    cp "${FUCHSIA_BUILD_DIR}/${IMAGE_FVM_RAW}" "${fvmimg}"
    "${ZIRCON_TOOLS_DIR}/fvm" "${fvmimg}" extend --length "${newsize}"
    echo "done"
  else
    fx-error "could not extend fvm, unable to stat fvm image"
  fi
fi

于是就能运行了~~

随手一个ls,然后…

$ ls
/boot/bin/sh: 4: Cannot create child process: -1 (ZX_ERR_INTERNAL): failed to resolve fuchsia-pkg://fuchsia.com/ls#bin/ls

去看代码,这命令真没了o.o按理来说不应该啊

于是想了想,还是把tree再拉过来用下吧,顺便感谢@Patrick(https://blog.simplypatrick.com) 提醒,可以不用修改tree的代码,将BUILD.gn修改成这样
