Magento is infamous for being over-engineered and hard to customized for developers.

Here are some complains:

Magento 2 is complete trash, stay away at all costs

https://www.reddit.com/r/Magento/comments/egcb2g/magento_2_is_complete_trash_stay_away_at_all_costs/

Magento 2 was their chance to show they learned lessons from how Magento 1 development went. >They proved instead that they learned all the wrong things, and doubled down on many of the architectural mistakes.

Hirofumi Nakai Improved

The Doomsday rule was devised by John Conway in 1973 to compute the day of week in your head (https://en.wikipedia.org/wiki/Doomsday_rule). Others have made improvements for easier mental calculation.

Currently, the simplest one is published in 2023 in the paper "A Simple Formula for Doomsday" by Hirofumi Nakai (https://thatsmaths.com/2023/06/22/a-simple-formula-for-the-weekday/).

• split the year into century part and the remaining 2-digit part: Y = 100c + y
• compute the modulo 4 of these 2 parts: c₄ = c % 4, y₄ = y % 4
• the Doomsday would be (5(c₄ + y₄ - 1) + 10y) % 7

it's a bug that only happens when the article starts with a blockquote tag. OSNews is working on a fix (https://mstdn.social/@osnews/113958357150579777)

Fixes (can be applied in browser console):

• add something before the blockquote jQuery('.front-view-content.full-post > blockquote:first-child').parent().prepend('<p>&nbsp;</p>')

• a better fix from https://mstdn.social/@mattsheffield@mastodon.social/113971810490442290 jQuery('.front-view-content.full-post').css('clear','both')
