Hi:

perl -e 'print "hello world!\n"'

A simple filter:

perl -ne 'print if /REGEX/'

Filter out blank lines (in place):

Прямо сейчас в Амстердаме начинается конференция CSS Day и мы решили попробовать новый формат и сделать текстовую трансляцию в течение дня. Программа: http://cssday.nl/programme

Первый доклад

Эрик Мейер про веб-шрифты в CSS — http://cssday.nl/programme#eric-meyer

Не забывайте указывать локальные (несколько, при возможности) псевдонимы для шрифтов в @font-face, на случай, если шрифты уже установлены.
Если оформление заголовков в тексте веб-шрифтом ещё нормально, то оформление всего текста вызвает проблемы с быстродействием на мобильных.

Generate the list yourself:

$ cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS*.sdk/System/Library/Frameworks/UIKit.framework/Headers
$ grep UI_APPEARANCE_SELECTOR ./*     | \
  sed 's/NS_AVAILABLE_IOS(.*)//g'     | \
  sed 's/NS_DEPRECATED_IOS(.*)//g'    | \
  sed 's/API_AVAILABLE(.*)//g'        | \
  sed 's/API_UNAVAILABLE(.*)//g'      | \
 sed 's/UI_APPEARANCE_SELECTOR//g' | \

SourceTree does not yet officially support Kaleidoscope 2, so here is how to set it up:

You can try selecting Kaleidoscope, but we have had reports of mixed results. Some people have rebuilt their launch services database and restarted and been able to use Kaleidoscope this way:

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
