kylemarsh / Strings, Variables and Function Calls
Created August 14, 2012 19:33
Explaining a variable-passing problem a friend was having.
# Basics (things you already know)
"abc" # the string "abc"
SomeVar = "abc" # SomeVar is a variable whose value is the string "abc"
func() # func is a function we're calling with no arguments
func("abc") # call func and pass the string "abc" as the first argument
func(SomeVar) # call func and pass the value stored in the variable SomeVar as the first argument
# Extrapolating from the basics
"abc" + "def" # append the string "def" to the string "abc". result is the string "abcdef" *string append may be different in Access
"def" + SomeVar # append the value stored in SomeVar to the string "def". result is the string "defabc" if SomeVar contains "abc"

Install and Run InfluxDB on a DreamHost VPS

Installing InfluxDB on a DreamHost VPS

Get the VPS

  1. If you don't already have one (or you want InfluxDB to have its own) Head to [the panel][0] and get thyself a VPS!
  2. Hit the "Configure" button and on the next page, the "Public Keys" link in the "Root SSH Keys" section.
  3. Create (or upload) a new keypair for your VPS. Safe the private key to your local ~/.ssh/ps123456.rsa or something.
  4. Head over to the [users section][1] and add a new, non-admin user (this example will use newinfluxdb). We'll come back to this later.

Plot gamma ray burst data from the FERMI GBM Burst catalog using astropy
# Code to generate a dotfield for my galaxy top hat*. Rather than placing my
# "stars" randomly, I wanted to use a pattern based in real astronomy data
# of some sort. In browsing online I realized for the first time how to read
# those elliptical maps of the sky you see astronomers use all the time. I
# decided to get data from the equator of one of those maps to put around my
# hat.
#
# Unfortunately, all the maps I could find were either too dense or too
# sparse so I realized I'd have to dig into the actual data myself and
# generate an appropriate map. I decided on detected Gamma Ray Bursts**
