What do you like to see in tech talks?

I want to see in the first 5 minutes: 1) a simple explanation of what it is - don't assume I know anything about the problem 2) why this solution is better than the others/what unique problem it is solving 3) a quick demo. As an engineer then I want to see the architecture from a high level and how to most easily implement into my shop. Save the code deep dives for last unless there's some really unique and interesting things going on under the hood. Underpromise and overdeliver.

Great question. From a consumer only perspective:

I always like where there is an easy method to review the presentation again. Like a link to a video of it. Also a link to read more detail. Hate when text is presented to fast. Hate when talker is too fast. This is a common problem with not experienced. Typically showing me code is a waste as I cannot mentally process that level of information and still hear you. I find it very useful, and this should be obvious, when the talk matches the visual. I like to use one to complement the other, not provide an overload of information.

Congratulations on your upcoming presentation at pgconf.eu! It's always refreshing to see new faces sharing their passion in the tech world. Speaking from personal experience, my first conference talk was a rollercoaster of emotions - from nervousness to exhilaration. One key lesson I learned was the importance of weaving real-world examples into the technical details. Audiences tend to connect more when they see how your work translates into practical solutions. So, in your "SQL micro-framework" presentation, consider sharing a memorable real-life scenario where it made a significant impact. It's an effective way to engage your audience and make your talk more relatable. Best of luck with your presentation – you've got this!

Don't put up multiple slides with long lines of code. A few slides with a few lines of code where everything is very clear is fine. Some people just have every slide be many lines of small code. In terms of slide text, less is more.

What I don’t like to see: slides where >50% are memes.

* One thing I don't want to see is a long introduction. Start out by discussing the problem your technology solves and what an audience member will gain from your talk. I don't like having to sit through 5-10 minutes of "This is me and this is what my company does." before I even know if I'm super interested to sit through the thing. A bit of self-promotion that's relevant to your talk is great, but save it for a bit after the introduction of the talk once you've got the audience hooked.

* I would suggest to watch a few of Fireship's ____ in 100 second videos, where some funny nerd covers the basics of different technology topics in 100 seconds . It's a good mix of overview, tiny code snippets, diagrams, explanations, and humor. The pace is faster than a talk needs to be due to the very short time limit, but that might be the right kind of vibe to try and nail.

* I don't think you necessarily need to include long code snippets, but short code snippets to illustrate points are great. Also, please include some short links to code repos with your longer examples in your slides. I like to look at videos to learn some technology or technique, but it's tough to absorb with the long code examples in video format spread throughout multiple files. Provide a link to a repo for your talk in the slides.

#1 best thing in a talk is a real-life story. Especially a weird bug or something. Tell us what happened, but don't drag it out too long.

Not too much code. Don't show boilerplate, just show any clever or interesting bits. Show us how the magic happens. Draw boxes around implementation details, because we don't care.

Don't waste too much time. If your talk starts out like an internet recipe with a story about your granny, I'm not watching.
