Fine-tuning a Keras model. Updated to the Keras 2.0 API.
'''This script goes along the blog post
"Building powerful image classification models using very little data"
from blog.keras.io.
It uses data that can be downloaded at:
https://www.kaggle.com/c/dogs-vs-cats/data
In our setup, we:
- created a data/ folder
- created train/ and validation/ subfolders inside data/
- created cats/ and dogs/ subfolders inside train/ and validation/
- put the cat pictures index 0-999 in data/train/cats

由于 Surge for ios 的条目数量不能过大,导致手机内存不足,所以将 GFW 和 广告过滤集中后进行了人工挑选,压缩在 1万条左右,你仍然可以自己添加大约 900条规则,理论上足够你长久使用了,配置文件默认是直连,方便普通国内用户使用。配置文件中,我自己调整过的、有可能有误伤的条目我都放在了前面,方便你自己修改,不过运行自 2016/01 ~ 2016/02 我自己日常没有遇到问题。有误伤不要怕,打开软件可以自己调试添加。

#我的注释都是 # 开头,所以如果你用 vim,直接 :g/^#/d 就可以一次性清除所有注释
#开头这段skip包含以下几个目的:1,私网IP跳过,提高内网性能;2,苹果的一些服务跳过,比如公共热点wifi要先测试captive.apple.com。可解决很多内网的 TCP毛病,例如 kodi remote软件无法遥控
skip-proxy = 10.0.0.0/8,169.254/16,172.16.0.0/12,192.168.0.0/16,224.0.0.0/4, localhost, *.local,api.smoot.apple.com,configuration.apple.com,xp.apple.com,smp-device-content.apple.com,guzzoni.apple.com,captive.apple.com,*.ess.apple.com,*.push.apple.com,*.push-apple.com.akadns.net
#下面这一段则是完全跳过 Surge,最重要的一个是让 UDP包可以传输,解决很多内网毛病,例如DLNA,NFS或者btsync等组播类/UDP类应用
bypass-tun = 10.0.0.0/8, 169.254.0.0/16, 172.16.0.0/12, 192.168.0.0/16, 224.0.0.0/4, 0.0.0.0/8, 1.0.0.0/9, 1.160.0.0/11, 1.192.0.0/11, 10.0.0.0/8, 14.0.0.0/11, 14.96.0.0/11, 14.128.0.0/11, 14.192.0.0/11, 27.0.0.0/10, 27.96.0.0/11, 27.128.0.0/9, 36.0.0.0/10, 36.96.0.0/11, 36.128.0.0/9, 39.0.0.0/11, 39.64.0.0/10, 39.128.0.0/10, 42.0.0.0/8, 43.224.0.0/11, 45.64.0.0/10, 47.64.0.0/10, 49.0.0.0/9, 49.128.0.0/11, 49.192.0.0/10, 54.192.0.0/11, 58.0.0.0/9, 58.128.0.0/11, 58.192.0.0/10, 59.32.0.0/11, 5

Yet another config for Surge.app

Install

  1. Modify index.txt with your output path and proxy info
  2. Use Text Builder to build configuration for Surge: $ text-builder -index /path/to/index.txt Or run $ sh build-all to build all your index files.
  3. Import configuration via AirDrop/iTunes/Dropbox/iCloud

深圳电信,DNS测速,namebench 2015-01-14

https://code.google.com/p/namebench/

基于我自身浏览习惯+深圳电信线路的namebench测试,整合了以下公共DNS列表的测试结果:

个人结论是:无论使用国内还是国外的DNS,都在解析网站时受到相当的干扰,如果不是劫持和黑洞,就是纯粹的丢包超时。只有在用户端设好工具,所有海外DNS请求走加密通道,才可以杜绝触发黑洞和过滤。在用户端想办法过滤虚假的DNS结果也可行,但并不能真正解决超时的使用问题。
