Tuning the environment

In Software Engineering everything already exists

algorithms & data structures

programming languages & compilers/interpreters

software libraries & configuration files

...

The basic principle of software engineering is REUSE

the issue is how to reuse effectively what exists

The Reuse Pros you don't loose time coding if something does not work, it's not your fault! Cons hard to master, but it's worth

Pros

you don't loose time coding

if something does not work, it's not your fault!

Cons

hard to master, but it's worth

Towards a catalog of common CPM patterns Copy/Paste/Modify is sometimes seen as a tabu everybody does it, but no one wants to admit it We need a public catalog of world-wide industrial-strength CPM patterns to evangelize the methodology to show the benefits to newbies to follow the wave of the GoF Design Pattern buzz word

Copy/Paste/Modify is sometimes seen as a tabu

everybody does it, but no one wants to admit it

We need a public catalog of world-wide industrial-strength CPM patterns

to evangelize the methodology

to show the benefits to newbies

to follow the wave of the GoF Design Pattern buzz word

#1: PowerPoint CPM Goal Make a “new” presentation in a short time, but don't plage the existing(s) one(s) Best practices reuse images reuse the theme reuse impressive words or sentences reuse the bibliography Pitfalls and workaround there is only the pdf of the presentation use a screenshot tool to copy what you need!

Goal

Make a “new” presentation in a short time, but don't plage the existing(s) one(s)

Best practices

reuse images

reuse the theme

reuse impressive words or sentences

reuse the bibliography

Pitfalls and workaround

there is only the pdf of the presentation

use a screenshot tool to copy what you need!

#2: Source code CPM (1/2) Search engines are your best friends http://www.google.com/codesearch http://www.koders.com/ ... Best practices find the code, copy/paste it, compile, enjoy ! ;-) Pitfalls and workarounds the copied/pasted code does not compile copy/paste a larger portion of code

Search engines are your best friends

...

Best practices

find the code, copy/paste it, compile, enjoy ! ;-)

Pitfalls and workarounds

the copied/pasted code does not compile

copy/paste a larger portion of code

#2: Source code CPM (2/2) NEVER infring copyrighted material in reusing sources If you really have to, obfuscate your code

NEVER infring copyrighted material in reusing sources

If you really have to, obfuscate your code

Tuning the environment Keyboard CTRL + c/v/s should be very accessible if possible, reconfigure the mappings to make them even easier to type Mouse the pointer should be very accurate clean the dust very frequently Internet connection should be very fast, in order to download quickly the source of reuse IDEs install any code search engine plugin

Keyboard

CTRL + c/v/s should be very accessible

if possible, reconfigure the mappings to make them even easier to type

Mouse

the pointer should be very accurate

clean the dust very frequently

Internet connection

should be very fast, in order to download quickly the source of reuse

IDEs

install any code search engine plugin

Conclusions Reuse is the basic fundament of the past, present and future of Software Engineering Despite their importance, CPM patterns have always remained in the darkness A public catalog of CPM patterns can help newbies jump into the train of real Software Engineering

Notes This presentation wants just to be a funny 1 st April joke it does not encourage in copy/pasting copyrighted material it doesn't even promote copy/pasting as a Software Engineering methodology

This presentation wants just to be a funny 1 st April joke

it does not encourage in copy/pasting copyrighted material

it doesn't even promote copy/pasting as a Software Engineering methodology

Serious material When is not 1 st April, I like to speak about really true Software Engineering topics which I care a lot, as Unit Testing http://www.slideshare.net/alessiopace/embrace-unit-testing/ If you want to discuss with me about real methodology concerns, contact me
