interviewer tip


The best way I've found to interview candidate developers is to pair program with them to do real work on the actual code of the project that is hiring. If not possible, give programming exercise which is:

The exercise must involve working with current development tools.
The exercise must require the candidate to apply important features of the language.
The exercise must involve understanding and working with existing code.
The exercise must involve error handling.
The exercise must involve testing.
The exercise must offer scope for domain modelling.
The exercise must involve asking questions.
The exercise must be realistic.
The exercise must involve changing requirements.
The exercise must offer the candidate enough rope to hang themselves.
The exercise must test many different skills and practices.

A good interview programming exercise takes at least an hour. - http://nat.truemesh.com/archives/000630.html

我會花掉你夢想中的房子
把我生下來會花掉你一大筆錢
我會傷透你的心
開心工作,賺錢給我付托兒費。
我的零花錢一點兒也存不住
我知道你愛哥哥/姐姐/弟弟/妹妹比愛我多一些。
我弄壞了你的iPad、iPhone,還有電腦。
我看屏幕上癮都是你的錯
你大概沒法指望我來讓你抱孫子了
你會哭的,當我離開……並留給你最後一張賬單的時候

早上吃水果,可幫助消化吸收,有利通便,而且水果的酸甜滋味,可讓人一天都感覺神清氣爽。人的胃腸經過一夜的休息之後,消化功能不強。因此要選擇酸性不太強、澀味不太濃的水果,比如蘋果、梨、葡萄等。 - http://hk.apple.nextmedia.com/realtime/china/20140715/52692068

Some advantage of GIT over Mercurial - http://blog.extracheese.org[..]hy-i-switched-to-git-from-mercurial.html

#undo last commit
git reset HEAD^

#show files in a given commit
git show --pretty="format:" --name-only rev_number

#remove untracked files and directories
git clean -f -d

#track remote branch
git branch --track branch_name origin/master

# given you created a new local branch 'branch_name'
# pushes 'branch_name' to 'origin/branch_name', creating the remote branch for you
git push origin branch_name

#delete remote branch
git push origin :remote_branch_name
