Daily Weather Email – PYTHON – CRON – API

I was interested in the weatherunderground API for getting real time weather updates via the API and python.
I was particularly interested in learning how to use the JSON python module. So I thought I would give you people a quick and dirty write up of how I get a daily weather update with endless categories via email on linux using python.

Ok so here we go, don’t get all excited and post this on hacker news and crash my t1.micro at AWS.

Let’s have a lookie at the python script where the magic takes place. O Yeah you will need to get an API KEY from WeatherUnderground for this. Look here:

The API will look like this once you obtain your copy:

Here is the link for requests:
Ok let me break down the PY code:

It’s probably important to see what we get back from the API in JSON so the below code makes sense. Here we go, this is just pretty printing the JSON using pythons PPRINT module, Showing this snippet first to help understand the code.



Ok let’s parse this JSON and send a freaking daily email with the fields we want, O Yeah.

Here is the script commenting on what we are doing.

Here is what comes out of this python script when we call the JSON variables we are attracted to:

Ok let’s wrap this biatch into a shell script and have it call mail on linux so I can get a daily updates on the weather for Milford CT whenever I call the cron.

Here is the directory structure I setup for the scripts:

Here is the bash script that I wrote to bring it all together, it calls the python script and writes a log and mails it.

Here is the cron:

Here is my morning email message:

Hope you had fun, I did. O and let me know how bad this post is and how you can do it better.
Love you

Analytic’s – Fuckin A

Well I thought I would write up a quick post to demonstrate that even the slower kids like myself can achieve web visitors hitting their site if they put some effort behind it. I started this blog back in late 2012 and I only posted a couple of code snippets here and there. Then my coding skills developed a bit and I kept the domain alive so it started to get a bit more traffic. Anyway this really is not much traffic, but it’s neat to say that I have had my blog up and recording visits for some time now.

CYGWIN – clear.exe from scratch C Program

Hello all,

TL;DR – I wrote a C program to use as clear.exe on cygwin, I know about CTRL-L but I wanted a binary for scripts, and I am used to typing clear at a terminal

I was recently enforced to use Windows as my daily computer at work for all types of compliance PCI reasons, reasons that I do not wish to dive into. However I am now on Windows, I spend most of my day in a BASH shell on a remote system, so it’s not that bad. However traversing around Windows with CMD or PS sucked. I was introduced to cygwin and I was really impressed, I was able to use a ton of tools that I was already familiar with on the Linux CLI. Native SSH,SCP were huge for me at this time, also the ability to customize the colors with the TTY settings was awesome.

One issue I ran into was I liked to use the clear command in my scripts and from the CLI when I want a fresh terminal. Well, I figured I could just re launch the cygwin installer and search for clear.exe and install it. This was not the case, unfortunately I was instructed to install ncurses and the associated libraries. I followed these recommendations and never got clear.exe to work.

So I did what any computer scientist would do, research how to write a C program on this and compile it and copy it to my $PATH and wouldn’t you know it works!!.

So Here it is in all it’s glory. clear.exe for Windows and CYGWIN:

### Clear no workie ###

Ok so we can see the clear program was not working in the above example. So I wrote the following lines of C code below and compiled them.

OK, cool, now you will need to get GCC on your Windows machine from the CYGWIN installer, so just re run the installer and search GCC, you can install it from there like so.

Ok now for the awesome stuff, it’s time to compile this with GCC and create a new clear.exe binary for Windows and CYGWIN.

Now that we see we can use the new executable to clear out cygwin shell, let’s copy it somewhere so we can just type “clear” to get what we want.

And there you have it, have fun!!!


Linux Restart Process / Application When Memory Threshold Is Reached

Here I needed to kill a c++ process that was leaking memory in order to save the server from meltdown. Very simple while loop that calls the external command “free” and parses it’s output with awk to store a variable. Pretty neat and it works.
