Project mention: Are you really wasting your time in Java without these 10 libraries? | dev.to | 2025-11-20
Apache Commons Lang and Google Guava play the same role in the ecosystem, even though the former predates the latter: fill in the gaps in the Java standard APIs. For example, one of the biggest current PITAs in modern Java is checked exceptions inside lambdas. Both libraries provide wrapping methods to handle this specific use case. In general, modern Java versions and Kotlin drastically diminish the need for these additional dependencies.

As a both old Linux and now decade user of MacOS, after I got used to no middle-click paste and no focus-follows-mouse:
1. Keyboard shortcuts are Emacs, Ctrl-A: start of line, E: end of line, K: kill selected or to end of line, Y to paste, etc. https://support.apple.com/en-au/102650#text
2. Karabiner elements (FOSS) fixes keyboard mappings outside of the Settings: https://karabiner-elements.pqrs.org/
3. I have the dock on the left hand side, not bottom and I have a 2 monitor (iMac 5K 27"+ Dell 4K 27") setup with the iMac flat in front of me and the curve/2nd to the right. Menu bar is then close to the main windows.
4. Menu bar widgets etc are fixable with thaw https://github.com/stonerl/Thaw
5. Window management via keyboard is fixable with rectangle https://rectangleapp.com/
6. Use Macports to add all the Linux/Unix utilities, works with MacOS properly (eg Python/Java frameworks). Ports can have variants, plus you can have multiple versions installed side-by-side with `port select`. https://www.macports.org/
Not sure about fonts, on a 5K iMac they're fine and the 4K Dell works too. You need to use a resolution that fits with Mac's ideas of resolution, so I've got the 5K and 4K both at 2560x1440, which is Mac's idea of 2x resolution.
