Already heard some great talks at #pycon_austria2025 , but the best and most important (and also funny) one today for me was the talk by Ines Panker with the title: "Software estimation is a delusion or is it just a misused tool?"

This is a talk everyone needs to see who ever wondered why actual software development always need soooo much time. Unfortunately the talk was not recorded. But there is blog post covering the same topics here: https://www.ines-panker.com/2020/11/04/estimation-is-a-delusion.html

Software estimation is a delusion

You will never be able to accurately estimate the time and effort it will take you to build a piece of software .. for as long as you keep doing new things. It is impossible to estimate the time needed to do something you aren’t familiar with it. If you haven’t done a thing before and you don’t have good statistics on how long these things usually take, what can you possibly base your estimate on? I know this is not the consensus among developers. Estimation is generally thought to be annoying, but doable. I’ve even met such devs that are very proud that they can estimate projects pretty accurately. But then you look at research and research paints a different picture. Research corroborates my personal experience, namely that developers are horrendous at estimating the required effort for software changed.

#statstab #315 What fraction of repeat experiments will have an effect size within the 95% confidence interval of the first experiment?

Thoughts: CV is a great place to learn. We see the same answer as Cumming: 83%

What fraction of repeat experiments will have an effect size within the 95% confidence interval of the first experiment?

Let's stick to an ideal situation with random sampling, Gaussian populations, equal variances, no P-hacking, etc. Step 1. You run an experiment say comparing two sample means, and compute a 95%
