System "freezes" are often caused by running too many, too large programs and running out of available memory. Use `free` to see if you have swap space, read `man mkswap swapon fstab fallocate` to create some. Swap space must be contiguous. use `mkswap` or `fallocate`, not `dd`. Traditionally, swap space of 1.5 × RAM has been recommended, but YMMV. If you don't plan to hibernate your system, you can have less than 1.0 × RAM.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
