Version control
Git, SVN (Subversion), MercurialOld: CVS, Perforce
Comparison
Simple:git clone <url>
git pull/push
git add/commit
Understanding Git Conceptually
Tortoise SVN / Git, Gitg
Diff toolsWinMergeMeld, KDiff3Beyond Compare
Bug Tracking
Jira, Bugzilla
Build System
Makefile, CMakeAnt -> Ivy
Pythonmay be used ;)
Buildserver
Static analysersNeeds only source code!
Static analysers
Java: FindBugs, CheckstyleC++: Eclipse, Clang, Coverity, KlocWork
Obj-C: ClangOther: JSLint, Pylint, Perl::Critic, ...
Dynamic AnalysisNeeds scenarios!
Good to run with UT suite.Debuggers, Profilers, Tracers...
UT Frameworks
● Provide infra for UT○ Integrate to IDEs / CI○ Reporting○ Convenient APIs
JUnit, CxxTest, ...
DebuggersConditional breakpoints
Data breakpointsWatch expressions
Reverse, Rec-ReplayRemote debugging
Offline debuggingDebugging in emulator!
Data Display Debugger
Profilers
● speed, resource usage, cachePerl perl -d:NYTProf myscript.pl
Python python -m cProfile myscript.py
+pycallgraph
Java NetBeans, GC Viewer, here (rus)
You can do measurements directly in code!

Browserdev tools
Productivity tools
Linux!● KDE, krusader, yakuake, redshift● VLC, Inkscape, Gimp● Use console!!! Vim, Emacs
Windows:● RocketDock, Actual Title Buttons, F.lux, WorkRave● Browser, File Manager, 7z, SysInternals suite● Punto Switcher, Keyboard, ConEmu, Putty● Notepad++, STDU Viewer, Paint.Net, WinSCP, UltraVNC
IDE
● Visual Studio Windows, .Net, C/C++● IntelliJ IDEA Java, Scala, Python...● Xcode Obj-C, C/C++, Python● PyCharm Python● Padre Perl
Eclipse
● Java● C/C++ CDT● Python PyDev● Perl EPIC● Node.js● … lots of plugins!
Prototyping
● Python, JS, Node.js● Arduino● Online:
○ Coding Ground○ JSFiddle
Online toolsValidatorsDrawing
Diagrams: GliffyMockups: Balsamiq
Google Docs, Google Drive, DropboxFreeMind, github, trello, WeTransfer, doodle
Logs, Dumps, Event Traces
● “Debug by prints”○ Embedded / multithreaded
● Log to file, to ram (may be shared)○ Filter by module/severity
● Dump part of the state○ Stats
● Event Traces○ Binary, lightweight
Statistics
● Event counts○ In domain, or internal○ Amount of function calls
● Time of processing● Latency● CPU/RAM usage
Diagnostics
● Now check them all!● During normal operation● Special diagnostics mode
○ For intrusive things
Crash & Bug reporting
Environment infoStack tracesDumps, Stats, Logs...
Visualize!
geomview,meshlab
Graphs
How it might be interesting?..
GraphViz
Instrumentation
Hooks Scripts
+
Simulators
● CNC● ...● User-mode LinuxPart of the system is replaced with a simulated one.
CLI - Command Line
● Interactive● One-shot
Increases usability &Allows automation!
Scripting Engine
● JS, Python, Lua, C# for .Net● Examples
○ Atom, Sublime text editors○ Some games use Lua○ VirtualBox uses Python
● Even better automation! ^_^
