  • The same reason a lot of companies support a community edition. It means that people can use, learn and become experienced with the product without forking over a tonne of money.

    This results in a larger number of developers, add-ons and community surrounding the product.

    This makes it a more appealing product for companies looking to build a business using it.

    It’s the same reason you can use AWS for free, get some JetBrains products for free and often find community editions for similar products to Magento.












  • Let’s number the dudes in your image form left to right: 1, 2, 3 and 4.

    Dudes 3 and 4 have no useful information. They stay silent.

    Dude 1 can see one of each hat colour on the dudes in front, but cannot determine their own colour without knowing the hat colour of dude 4. They stay silent.

    Dude 2 can see the hat colour of dude 3. They can determine that either they themself or the dude behind must have a different hat colour. The dude behind - dude 1 - can see both of the hat colours in front, but stays silent. This lets dude 2 know that they and dude 3 must be different colours (otherwise dude 1 would have known their own hat colour).

    Therefore, dude 2 knows their own hat colour must be different to the dude in front and announces the colour of their own hat.


  • Good question. I am now a software developer, but in a previous career I was a logistics manager. In that job I had a lot of repetitive report downloading and creating. It would take hours each day. I used techniques taught in that book to automate downloading reports directly, as well as generating some in SAP by automating mouse and keyboard movements, as well as generating CSVs and Excel spreadsheets. In all cases I either cut the time required or at least the time I had to be physically present. Many jobs could have similar applications of a little Python, I imagine. Certainly not all jobs though, of course.
