Tips how to give a good talk

• Presenting what you understand.  Your friends will be more likely to appreciate a talk that they understand which mean the presenter must understand the subject first.
• Don't just summarize the paper.  It will not be convincing.  You need to present some evidence for what you are claiming, such as, the processor X is very good becuase it is very fast, now, show me the benchmark result for this processor.  Therefore, present some hard fact that included in the full paper.
• Talk about what you think about that paper.  This is your opinion.  The audience like to hear opinion and give them something to discuss.
• Prepare your slide.  A big, easy to see, clear layout, slide will relieve the eyes strain of your friends.  Remember they all have to sit through 8 papers!
