(Author here.) It's great to see my write-up on HN, and I'm glad to see it generating good discussion here. Since several people have asked, I have now made my 'metime' tracking app open source: https://github.com/jdleesmiller/metime Being in London, I have just woken up, so I will now be more able to answer any questions!
Hi author. Small nit: consider changing your title to "their" time rather than "he" since you talk about " a technical co-founder". There's no need to use gendered language in the general case, and gendered language needlessly encourages gendered based identification. Imagine if you included your race and ethnicity and sexuality in the title - that'd feel silly, right? It would limit the audience who found the piece…
For the avoidance of doubt, I do say in the article that:
> The CTO role is a very diverse one, and I don’t expect that the results here will be true in general. This is just my story. I hope it is an interesting one, and it is uniquely backed by data!
So, the subject is me, and I am a male. I did not intend to exclude anyone by using "him".
(I can't change the title on HN myself, but if someone who can wants to do so, please feel free.)
