Less clever, but maybe nice to know you can also use grep

tail -f log/development.log|grep --context=3 some_string_you_want

or

tail -f log/development.log|grep -v some_string_you_dont_want_to_see

for more info, check this screencast on grep

#30 楼 @poshboytl

Thanks for your kind words, the cast will be done in a few days, then will be uploaded to my vps. You will receive a link by that time.

BTW, this cast is for railscasts-china, not part of my happycasts.

#9 楼 @poshboytl Yes, and mine: [email protected]

Sent you a mail already, plz check

@poshboytl I want to contribute a screencast to Railscasts-china.com, it is a summarization of this post http://ruby-china.org/topics/1222

Will cover:

• omnifunc
• ctags
• snipmate
• zencoding
• ...

If your permission granted, the video shall be ready in a week or so. The format will follow http://happycasts.net/ style(10 mins, done on Ubuntu), so what would you say? Any suggestion or requirement is welcome.

#2 楼 @xufeng Thank you so much, http://happycasts.net sets its focus on Linux, but we have a lot of git and vim things there, some of them might be useful even if you are on Mac, maybe you will like: Ctags: http://happycasts.net/episodes/25 Fuzzyfinder: http://happycasts.net/episodes/24

@lidashuang

Thx for sharing, love it.

Long long ago, I developed a rails app named happywords https://github.com/happypeter/happywords, it is by far the best English learning web app the world has ever seen...

Sorry, I lied, it's still crap.

My own Best thing ever:

• Best beginner tutorial: VIM USER MANUAL, you can get it by typing :h usr_01.txt in vim
• Best screencast: http://www.derekwyatt.org/category/vim/

Big Warning: No one can learn vim by reading, you need to learn by watching how smart guys actually using vim. The Derek's screencasts was really the thing that got me believe in "vim was made for efficiency", before that vim was a horriable energy sucker to me.

I think Rails is great for beginners, I started learning rails when I had no idea what a web app was, yet it worked well to guide me through, all the things just fell into its place when you were building sth REAL.

I think there are people in UCB thinks the same, that's why they brought out this: https://www.coursera.org/course/saas

About The Course This course teaches fundamental processes of software engineering using the highly-productive Agile development method for Software as a Service (SaaS) using Ruby on Rails.

http://happycasts.net/episodes/18 介绍在 ubuntu 上搭建 rails 开发环境，包括用 rvm 安装 ruby 管理 gem，mysql 安装，以及通过安装 passenger 将 rails 运行在 apache 之上。

Thx for sharing this, love it!

Let's add value!

#4 楼 @huacnlee Reputation system, Yes! +1

#17 楼 @ruohanc I've tried 3 or 4 recordmydesktop sort of software in Linux over the years, but none really worked. So I finally used

1. Screenflow running on Mac, with Linux running as a virtualbox img, then I will record my whole screen, do a bit video editing to get only the VM window, shitty, dirty...pupupu..
2. the thing that shows my key strokes is *keycastr, it is also, I suppose, only available on Mac.
3. more info: http://happycasts.net/about

#13 楼 @poshboytl

I am a screencastr at http://happycasts.net, most of my videos are Linux basics, but sometimes I also do ROR: http://happycasts.net/episodes/18

Will see what I can do for railscasts-china.

Be strong, Be positive, Be comunicating, Be a real man!

vim forever

My people!!!
