Algorithms that describe a researcher’s mind

Published by Joni on July 14, 2020

Algorithms that describe a researcher’s mind: (a) Work on the paper “closest to publication”. => downside: can reduce the willingness to solve difficult problems because they are farther from publication (b) Always switch to more interesting topic, when you see one. => downside: you’ll never get anything published (but upside can be that you learn a lot about different topics,…

Published by Joni on May 30, 2020

Mari Luukkainen kysyi LinkedInissä “Voiko kokenut markkinoija oppia kasvuhakkerointia?” Marin kokemus on seuraavanlainen: ”Olen rekrytoinut kasvuhakkerointi- tai vastaavaan rooliin muutaman vuoden aikana 12 kokenutta markkinoijaa ja 25 henkilöä joilla ei ole ollut markkinoinnista juurikaan kokemusta.” “Näistä henkilöistä tehokkaan ja systemaattisen kasvuhakkerointiprosessin oppi 0/12 ja 25/25.” “Kasvuhakkeroinnissa olennaista on saada asiat hoidettua.

Published by Joni on May 5, 2020

Some of my observations about coronavirus and economy. It’s striking how FEW people we need to sustain many. More than a billion people are in physical isolation, BUT utilities (electricity, water, internet) working perfectly.

Unit of cognitive effort

Published by Joni on May 3, 2020
