====== Эффективный программинг ======

===== Linux/bash =====

  * navigate with pushd <path>, popd
  * drag objects from Nautilus to terminal
  * use vars<code>
denis@denishp2-ub:/$ a='cd /etc'
denis@denishp2-ub:/$ echo $a
cd /etc
denis@denishp2-ub:/$ $a
denis@denishp2-ub:/etc$ </code>
  * use ''~/.bash_aliases'' (create if doesn't exist)<code>
alias robo='cd ~/PrjEclipse/jroboplc'</code>
  * use Groovy as alternative to bash
  * use Ruby as alternative to bash

===== Eclipse =====
  * use shortcuts list (Ctrl+Shift+L)
  * use Key Promoter plugin. Help-Install New Software -> http://update.mousefeed.com/
  * cool shortcuts:<code>
Ctrl-Shift-T        Goto to class (use capitals)
Ctrl-Shift-R        Goto to file
Ctrl-O              Symbol list
Ctrl-J              Incremental search
Ctrl-E              Recently edited files
Alt-Shift-L         Introduce variable
Alt-Shift-Up        Escalating selection</code>

===== Automation =====
  * Gant (build tool) http://gant.codehaus.org/
  * Gradle (build tool) http://www.gradle.org/
  * Selenium (web applications testing)

===== Codewriting =====
  * plenty of short methods against few huge ones. Three lines of code for a method doesn't take much time to figure out what that method does. If you put lots of comments into your method it is a sign to split it up.
  * FindBugs - static analysis tool (java)
  * PMD - source analysis tool (java)
  * Panopticode - bunch of analysis tools (java)
  * Cuberture - static analysis (java/groovy)

===== Points =====
  * Prefer typing over mousing.
  * Take the time to learn all the hidden keyboard shortcuts of your universe.
  * For any symmetric operation on multiple lines of text, find a pattern and record a macro.
  * Don’t type the same commands over and over again.
  * Spend a little time each day to make every day more productive.
  * Replace file hierarchies with search.
  * Don’t spend time doing by hand what you can automate.
  * Performing simple, repetitive tasks squanders your concentration.
  * Timebox speculative development.
  * Use virtualization to canonicalize dependencies for your projects.
  * Out-of-date documentation is worse than none because it is actively misleading.
  * Always keep “living” documentation.
  * Whiteboard + digital camera trumps a CASE tool.
  * Repetition is the single most diminishing force in software development.
  * Testing is the engineering rigor of software development.
  * Refactor comments to methods.
  * Static analysis tools represent cheap verification.
  * Don’t create global variables, even the object kind.
  * YAGNI - “YOU AIN’T GONNA NEED IT”
  * Don’t pay complexity tax unless you absolutely must.
  * Maximize work on essential complexity; kill accidental complexity.
  * Don’t pay complexity tax unless you absolutely must.
  * Encapsulate all implementation details away from public methods.
  * Find your perfect editor and learn it inside and out.
  * Good knowledge of regular expressions can save orders of magnitude of effort.
  * Use a “real” scripting language for automation chores.
  * Keep knowledge as plain text
===== Books =====
  * "The Mythical Man-Month"
  * Hunt and Thomas’s "The Pragmatic Programmer" (Addison-Wesley)
  * Beck’s "Smalltalk Best Practice Patterns" (Prentice Hall)
