• 07:13 UTC (new) (history) 2018-02-25 Simple way of assigning formulas to fields and columns in Org tables . . . . Marcin Borkowski – Today I’m going to share a simple trick concerning Org-mode spreadsheet tables. I knew that I could press C-u C-c = in an Org-mode table cell to install a formula in that cell (or C-c = to install a column formula). However, there is a simpler way: you can just type := followed by the formula and press TAB, RET or C-c C-c. (Without a colon, it installs a column formula.) Very handy! (And it was in the manual all along… Once more I learned that at least skimming through the manual from time to time is a good idea!)

• 20:23 UTC (new) (history) 2018-02-12 append-next-kill . . . . Marcin Borkowski – Today I’d like to share a simple trick which I learned a few days ago. It is well-known that if you perform a few killing commands in a row (like C-k or M-d), only one entry is put into the kill ring. Sometimes, however, I want to kill things in different places and still combine them into one kill ring entry. Enter C-M-w, or M-x append-next-kill. It makes the next killing command append its prey to the last kill ring entry.

• 20:52 UTC (new) (history) 2018-01-29 A simple script for shuffling exam questions . . . . Marcin Borkowski – As we approach the end of the semester, my free time shrinks to nearly zero. Today I’m only going to share a simple tip. Last week, I prepared an exam. I wanted 10 questions, each one taken from one chapter of the lecture. I also wanted 6 sets (4 for the exam and 2 for the retake). And I wanted no bias (even unconscious) – problem sets for the retake should be neither easier nor harder than for the first attempt etc.
