Input & Output

2007年因为opera博客被封,决定自己注册域名、购买空间,创办个人网站。一直维持个人小站、技术生活大杂烩博客。这些年网络世界发生了翻天覆地的变化,内容背后更多的是网络社交关系。现在分享的平台太多,博客、微信、公众号、medium、简书、twitter、Facebook、音频(如喜马拉雅)、视频(youku\youtube\抖音)、知乎、豆瓣。

周围的朋友,也有很多人通过网络分享精彩的生活,涉及绘画、美食、健身、旅行、育儿等等。百家争鸣,百花齐放!

每个人都是一个系统,可以通过阅读、旅行、社交等等进行输入。然后内部加工(思考)后通过言行进行输出。输出的可能是知识、思想、价值观、生活感想等等。网络也是一个个性展现的大平台,一个更加开放包容的平台。

现在博客写的太少,估计看的人也少,而且基本都是生活相关的。所以索性把博客搬到wordpress.com。我想梳理一下,选择自己擅长的领域,多思考、多对外有高质量的“输出”。

圣诞前

This is a blog from mobile app.

wordpress.com好像不被GFW屏蔽了,难得呀。不知道是临时,还是长期。虽然用手机码字写博客不会是经常,但随时随地能方便的发东西还是很不错的。

今天是周一,早上上班路上明显感觉大家都很赶时间,各种横冲直闯,狭路相逢勇者胜。

虽然还有一周才过圣诞节,上周已经有人开始提这事,开始问候了。小孩看到别人拍的公司的音乐圣诞树也是兴奋不已,去年老婆也在家里专门装扮了一个小圣诞树,闪烁的灯光,再加上精心挑选的背景音乐,让大人和小孩都进入了无限的遐想。

于是周末带小孩逛商场,果不其然多数商家费尽心思各种装扮,装点满满的圣诞树,可爱的小雪人,圣诞老人🎅和小鹿。有一个母婴店,用绳子挂满了中国剪纸的圣诞老人和英文祝福语,很有特色,当然这个剪纸也有可能是机器加工的,虽然没有灵魂,但还是五颜六色很漂亮。

最后吃完披萨,准备去看电影《龙猫》,这个应该非常适合小孩子。但当天只有日语版了,最后只能放弃。

用手机浏览器写博客

最近把一些不常用的手机客户端删除了,使用手机浏览器的移动版,最大的体验就是简洁、实用、高效。电脑网页版设计最复杂,其次是手机App。越是资源丰富的地方越被设计者滥用,而在资源有限的地方只做了最关键有用的事情。

之前用过wordpress的客户端,已经很方便了,比网页访问速度快,有些内容是延迟同步的。这个手机浏览器的H5版本也够简洁。

shadowsocks代理翻墙

Server:
sudo pip install shadowsocks
sudo ssserver -p 1080 -k my_password -m aes-256-cfb –user nobody -d start

Client:
sudo dnf copr enable librehat/shadowsocks
sudo dnf install shadowsocks-qt5

shadownsocks-qt5只是开放一个本地端口(sockv5)与服务器链接做转发,所以还需要再设置浏览器或者系统的代理,或者使用其他自动代理工具。

不知道是否之前SSH隧道代理使用的是免费的Openshift AWS 虚拟机,Google Hangout有时候不稳定,现在在另外一台付费AWS虚拟机上配置了shadowsocks,比之前好很多很多。

First ScyllaDB Summit

http://www.scylladb.com/summit/

Scylla is the world’s fastest column-store database: the functionality of Apache Cassandra with the speed of a light key/value store.

Raw speed isn’t just a nice benchmark or a low cloud bill. Scylla’s order of magnitude improvement in performance opens a wide range of possibilities.  Instead of designing a complex data model to achieve adequate performance, use a straightforward data model, eliminate complexity, and finish your NoSQL project in less time with fewer bugs.

Performance improvements enable not just reduction in hardware resources, but also a reduction in architecture, debugging, and devops labor. Scylla combines the  simple and familiar Cassandra architecture with new power to build a data model that fits the application, not tweak the model to fit the server.

Drop in replacement solution
