    1. Coronavirus isolation affects your brain — a neuroscientist explains how, and what to do about it

      1. Social media makes it possible for us socialise far and wide. Reach out to friends online, call your parents, and learn how to practice mindfulness or meditation.

      2. Head to the backyard for a dose of nature, or if you're in an apartment with no nature to gaze at, be sure to get to a green space for your exercise.

      3. To help improve your sleep, try sticking to a routine and avoid screen time for at least an hour before bed. And lay off the alcohol – it reduces the quality of your sleep.

      4. Just 10 minutes of exercise may improve our attention for the following two to four hours, so if you're struggling to focus, get that blood pumping.

      5. Give your isolation brain a boost by laying off the high-sugar or high-fat treats. Have healthy snacks on hand instead, like fruit, vegetables and nuts.

    3. IBM System/370 Mainframe emulated on a Raspberry Pi Zero

      @brianroemmele: I will let out a bit of a secret. I have been running a full IBM System/370 Mainframe on a $5 Raspberry Pi Zero for ~5 years. About 7 times faster System/370. Millions of lines of COBOL JCLs running flawless on a battery. Tested an entire bank's mainframe COBOL on it.

    4. LaTeX: Using a different font for glyphs used in commands like \sum

      Hello everyone. I consider myself fairly competent when it comes to my work with LaTeX, but as everyone who uses it knows, it is definetely strange sometimes. And right now I have a problem which just irks me in the wrong ways:

      I use XeTeX and a number of custom fonts for my documents, but when writing mathematical formulas I found out that the font I set for Greek letters (Gentium Plus) is used for letter commands like \alpha, \Alpha, ... but not for commands like \sum, \prod. As you can see in this example here. You can see XeTeX defaults to Computer Modern.

      I've looked all over the net for solutions but I can't find one. I'm using mathspec, amsmath, amsfonts, amssymb as my font related packages and I set my fonts like this:

      \setmainfont{Charis SIL}
      \setsansfont{Helvetica Now Display}
      \setmonofont[Scale=MatchLowercase]{Fira Code Retina}
      \setmathfont(Digits,Latin){Charis SIL}
      \setmathfont(Greek){Gentium Plus}
      

      I feel like I'm going insane not solving this problem. Should you require it, my entire LaTeX template is here on Github. Please help, thank you.
