What is the correct method to write measurements in English? Should it be:  1KG or 1 KG?  1M or 1 M?  1PM or 1 PM?  1GB or 1 GB?  1Kmph or 1 Kmph?  1Kbps or 1 Kbps?  or anything else?
Punctuation with units I remember reading somewhere that if a unit is abbreviated as one character, there must not be a space between the number and the unit (e.g., 5m, 26K). If the unit is abbreviated as two or more Characters, there must be a space between the number and the unit (e.g., "10 km", "USD 5").   Can you please help me find the source again? Is this recommendation correct?
I am typing to get a sale amount (by input) to be multiplied by a defined sales tax (0.08) and then have it print the total amount (sales tax times sale amount).  I run into this error. Anyone know what could be wrong or have any suggestions?   salesAmount = raw_input (["Insert sale amount here \n"]) ['Insert sale amount here \n']20.99 &gt;&gt;&gt; salesTax = 0.08 &gt;&gt;&gt; totalAmount = salesAmount * salesTax  Traceback (most recent call last):   File "&lt;pyshell#57&gt;", line 1, in &lt;module&gt;     totalAmount = salesAmount * salesTax TypeError: can't multiply sequence by non-int of type 'float' Get table names using SELECT statement in MySQL Is it possible to have f.lux (software that adjusts display's color temperature) on Ubuntu 14.04? f.lux is software which adjusts temperature of your display according to time of the day.

Many neural network books and tutorials spend a lot of time on the backpropagation algorithm, which is essentially a tool to compute the gradient.  Let's assume we are building a model with ~10K parameters / weights. Is it possible to run the optimization using some gradient free optimization algorithms?   I think computing the numerical gradient would be too slow, but how about other methods such as Nelder-Mead, Simulated Annealing or a Genetic Algorithm?  All the algorithms would suffer from local minima, why obsessed with gradient? How can I write multiple lines in a subscript? Is there a way to force a line break inside a math mode text?
