I do this on regular keyboards, too. I use a drop of ordinary white glue, and let it dry overnight. I put one on the “F”, “J”, “Tab”, and Keypad “5" (the existing ones on the “F” and “J” weren’t large enough for me). It makes a nice, smooth bump, large enough that it’s impossible to miss. But I think I’ll add one to…

Is this my cue to wave my cane and shout, “REAL MATH NERDS USED HP’S!” My HP-48SX was the shit and I still have an HP-48G today. My soul died a little bit a number of years ago when I had to buy my kids TI-83's for their high school math classes.

My own personal calculator: The first pocket calculator reached the US market in 1971, the year I graduated from college. I did a degree in physics with a slide rule and a book of logarithms. In the last half of my senior year the department got a Wang desktop calculator that could add, subtract, multiply and divide…

I never thought the ti calculators were any good. I use and still have my HP 48g graphing calculator from the 90s. for the record the newer 49g was crap and broke quickly. in 2012 my old HP 48g was able to out Calculate the newer TIs when calculating factorials

Funny, all you did was ask a question aloud and their conscience immediately went to “don’t accuse me of being racist”

The community and support as well as resources around a board are 800X more valuable than the board’s speed or capability list. I have several boards from kickstarters that utterly destroy the Pi, yet the Pi does a lot more because there is a huge thriving community around it.

I’ll go to the loo when it’s tied and when I get back I’m down by two.

Indeed. sWeat about Hebrew and any of the Arabic or Persian scripts? Are you looking at Farsi or Urdu? Simplified Chinese characters or traditional? The article reads like a High School paper by a student who thinks that he's found a secret. Too bad.

I'm going to share this article with 90% of the people I know. In all of my jobs I have quckly earned the annoying reputation of being able to fix anything simply because I am not afraid of breaking it first.

No one crams because they think it's the best way to study. They cram because they didn't study until the very end for whatever reason.

Unfortunately, cramming is often the ONLY method of study available to the student given other assignments and class scheduling. Cramming also really should be used in conjunction with other study methods as a last-minute refresh of material already gone over. Some types of exams you can actually cram for, such as…

But how much did he retain? There's a difference between immediate regurgitation of information and actual retention and understanding. Assuming the goal of education and studying is the latter, spaced repetition is a far better method of achieving that goal.

This is a terrible idea. If you are angry and you need to communicate it, then communicate it in person. If you are angry and you do not need to communicate it, then wait until you are calmed down and can write a rational email. Emailing angry is not a good idea.

I'm getting pretty sick and tired of hearing, "Why do I have to learn [algebra/geometry/trigonometry/calculus]? I'll never use it in the real world."

How about:
