While most personal philosophy, it gives some excellent advice about how to be both a good learner at your new language and a good “citizen” in the language community at large.
This editorial eloquently expresses the oft-stated complaint of many developers that they must spend so much time on process matters, project overhead, and other administrivia that actually finding time to write code becomes difficult.

If you use the Google Chrome browser (or one of it’s “respins”) and you have a lot memory (probably 8GB or more) on your system, you can allocate additional RAM to Chrome to improve performance in tasks such as switch tabs, scrolling long pages, etc. Just open Chrome and put chrome://flags/#max-tiles-for-interest-area in the address bar and change the value to “512”. Then click Relaunch Now to restart Chrome. This allocates 512MB of RAM to the main Chrome process.
Most of you probably already knew this, but it was news to me… If you want to save the size and position of an application window for the future, simply hold down the <Ctrl> key while clicking on the “X” button to close the window.
