Version Control – Source files Filename Control: Be disciplined and methodical about filenames. It might take you some time to actually get working, but in the long run this will save you time and reduce problems and errors. –filename.ext for standard filenames –filename_mmddyy.ext for backup of the file –filename_mmddyy.ext.bak current work-in-progress backup –filename_mmddyy_old.ext An old version of a backup

More Version Control Tips Add Version Information to the Tombstone Comment Block // Tombstone comments // Widget // Author: A. N. Other // Simple application that displays random messages on-screen // Started: // Last revision: // Last revision by: A. N. Other // Project status: In progress // // Code starts below. –Using Windows Search

More Version Control Tips Add Summary Information to the File

Version Control — Executables Add it to the filename Add it to the summary panel Use if the compiler or program that you use to create a setup application enables you to add specific version information to the file when it is being created

Software Version Control there are software applications that can help you to keep track of all the code and executables that you create while programming –GNU Revision Control System, ftp://ftp.gnu.org/pub/gnuftp://ftp.gnu.org/pub/gnu –JediVCS (Version Control System), –SourceJammer, –Arch, –TortoiseCVS,

Çekirgelere (Çaylak Programcılara) 30 yıllık Ustadan Son Tavsiyeler Sözdizimi (Syntax) yerine, programlamının anlamı (Semantics) üzerine yoğunlaşın Program yazmaya değil öncelikle program okumaya/incelemeye ağırlık verin Pratik, pratik, pratik Hata yapmaktan korkmayın Hata ayıklayıcılar (Debuggers) önemli araçlardır, onları kullanmayı öğrenin Öğrenmeyi öğrenin (Ağ teknolojileri) ve (bilgi işleme sistemleri donanımı) konusunda kendinizi geliştirin Son söz: “Programlama soğan soymaya benzer, soydukça altından yeni bir soğan katmanı çıkar. Gerçekten usta bir programcı olmak istiyorsanız, süzülen gözyaşlarınıza rağmen soymaya devam etmelisiniz”
