2. Agenda Fix your issue effectively with the developer What kind of questions do hackers expect ? How to ask a questions ? Understand the projects and distributions Upstream and downstream, release cycle, Learn how project manage issues Mailing lists, net news, issue tracker, irc Example of good and bad bug reports Tips to submit a patch2 3.

Despite this, hackers have a reputation for meeting simple questions with what looks like hostility or arrogance Hacker re (largely) volunteers. most of us would love nothing more than to deal with you as an equal and welcome you into our culture http://code.google.com/p/smartquestions/wiki/Introduction 10http://www.catb.org/~esr/faqs/smart-questions.html 11. How to ask questions (1) Try to reproduce the bug Do your best to identify the faulty package Verify that the bug is not already reportedand/or fixed Use tools to collect info (reportbug, apport) Describe the problem so that the developercan reproduce it Be kind and willing to help11 12.

Try to find an answer by reading a FAQ. Try to find an answer by inspection or experimentation. Try to find an answer by asking a skilled friend. If youre a programmer, try to find an answer byreading the source code. http://www.catb.org/~esr/faqs/smart-questions.html 14 15. Other questions Support requests, feature and policydiscussions, and development ideas all havetheir own dedicated mailing lists or forums. 15 16. Software vulnerability / SecurityIssues Coordinated Vulnerability Disclosure akaresponsible disclosure. report to the vendor privately, or to a privateservice that will likewise report to the vendorprivately. Do not distribute exploits.16 17. How the open source projects cooperate with others? Governance, Foundations, Organizations, Commercial entity, Projects, Distributions? 17 18. DistrosA Linux distribution is a member of the family of Unix-likeoperating systems built on top of the Linux kernel. Suchdistributions (often called distros for short) are Operatingsystems including a large collection of softwareapplications such as word processors, spreadsheets, mediaplayers, and database applications. The operating systemwill consist of the Linux kernel and, usually, a set oflibraries and utilities from the GNU project, with graphicssupport from the X Window System. http://en.wikipedia.org/wiki/Linux_distribution http://distrowatch.com/18 19. Upstream and distros Distros integrate upstream software projectslike GNOME, KDE, Linux Kernel, Xorg, Standardization, Quality Assurance 19 20.
