How to Give Technical Talks w Bill Stearns (2-Hours)

### Overview In this Wild West Hackin' Fest webcast, Bill Stearns (Active Countermeasures and Black Hills Information Security) presents a comprehensive guide on how to prepare and deliver effective technical presentations. Drawing on more than twenty years of industry and training experience, Stearns emphasizes that the primary goal of a technical talk is not merely reciting commands or facts, but motivating the audience and conveying genuine enthusiasm for the topic. The session offers practical advice spanning preparation logistics, slide design, vocal delivery, hands-on lab development, handling stage fright, and interacting with attendees.

### Key Topics - **Audience Understanding and Topic Scope**: Selecting a topic requires understanding the specific audience background and experience level. As demonstrated by the "cooking chicken" exercise, a general topic cannot be developed effectively without knowing the audience's preexisting knowledge and interests. - **Preparation and Logistical Redundancy**: Presenters must arrive early to test equipment and audio-visual setups. Stearns strongly advocates for hardware redundancy, advising speakers to carry multiple laptops, backup presentation remotes, spare batteries, display converters (DVI, HDMI, VGA), and backup internet access like cellular Wi-Fi pucks. Presentation files should exist on the laptop, online, and on a USB thumb drive kept in pocket. - **Slide Design and Pacing**: Slides should feature high-contrast formatting (dark text on light backgrounds) and readable fonts. Speakers should use concise phrases or visual cues rather than full scripts to avoid sounding robotic. A baseline pacing rule of approximately two minutes per slide is recommended, along with reserving 15% to 25% of time for questions. - **Overcoming Nervousness and Filler Words**: Rather than addressing a crowd collectively, speakers should treat presentations as a sequence of one-on-one conversations. To eliminate filler words, Stearns suggests practicing with an assistant who drops dollar coins into a glass jar whenever a filler is spoken. - **Hands-On Lab Design**: Technical labs should prioritize the "light bulb moment" over laborious setup. Stearns outlines a three-tier lab structure comprising a basic goal description, optional hints, and explicit step-by-step commands. Using packaged cross-platform software or preconfigured cloud VMs is encouraged over requiring students to compile source code.

### Technical Details & Speaker Equipment Stearns shares his specific setup and recommendations for virtual and in-person speaking: - Hardware: Razer webcam, Blue Yeti microphone, in-ear monitor, and dedicated LED lights to properly illuminate darker spaces. - Live Setup: Presentation remotes (such as Keyspan or Targus) with separate high-powered AAA laser pointers, avoiding low-power built-in watch battery pointers. - Power and Travel: Verifying multi-voltage compatibility (110–240V, 50/60Hz) and bringing appropriate plug adapters for international events.

### Takeaways - **Practice and Validation**: Rehearse presentations end-to-end with a timer. Record short video segments to review audio and video independently before combining them. Validate technical slides and lab walkthroughs with peer reviewers on fresh systems. - **Humility and Authenticity**: It is critical to admit when you do not know an answer rather than fabricating explanations, followed by researching the answer and delivering it later. - **Audience Connection**: Ditch protective physical barriers like podiums. Engage attendees visually, adjust the technical depth based on audience feedback, and provide persistent discussion channels (such as Discord) for continuous learning.
