You've posted this one 5 times over the last 2-3 years (see https://hn.algolia.com/?query=Gender%20is%20not%20a%20spectr... ).
Looking at your recent history, you've posted "Hacking chemical plants" 8 times over the past 2-3 years (see https://hn.algolia.com/?query=Hacking%20chemical%20plants%20... )
The sqlite one 4 times over the past 1-2 years (see https://hn.algolia.com/?query=Prefix%20for%20sqlite%20tmpfil... )
The "What Black Jack Pershing" again about every 6 months (https://hn.algolia.com/?query=What%20Black%20Jack%20Pershing... ).
Is there a reason for the reposts?
For example, I thought the SQLite link would be something new, rather than a re-link to a comment written in 2006-10-31.
