Python Hydrology


Recently I'm learning Python and encountered the Hydrology book. Had to upgrade some of python packages and some libraries needed to get working with the book. There is an instruction though about mostly using pip install packages need for the book. The problem is I can't get it work. It's missing some things so I did a little google and hopefully this is a compilation of the things I need to work with the examples of the book.

First off, I updated the apt-get

$ sudo apt-get update

Next is I installed the pip package manager. I'm not too sure but I have Ubuntu 10 and it doesn't have the pip installed. So I installed using the command below.

$ sudo apt-get install python-pip

Now the development packages for python.

$ sudo apt-get install python-dev

Most of the examples uses the scientific number packages so I installed numpy and other packages I'm not quite aware of. It's just that some of the examples probably in the later part of the book uses the other two packages aside from numpy.

$ sudo pip install numpy
$ sudo pip install xlrd
$ sudo pip install xlwt

Scipy needs some compilation and I think it has some packages built on top of fortran and some C++ source so I instlaled the essential and fortran packages with the commands.

$ sudo apt-get install libatlas-base-dev gfortran
$ sudo apt-get install build-essential

After installing these prerequisites, install the scipy with the command below.

$ sudo pip install scipy

For some plotting, installing the plot library is useful. There are also lots of examples using the plot.

$ sudo apt-get install python-matplotlib

This one I found the most useful package. It can be used as good reference to execute plotting some equations. At the very first stage of the book I encountered simple plotting of an array of x with the sin(x) as y coordinates and it's really helpful to visualize the equations with the plotter.

    Hi,
    It seems to me that you have written about my book, 'Python in Hydrology'. First of all thank you for finding the book useful. I will try to update these issues in the next version of book. If there is any question or comment, feel free to write to me.

    Really sorry for the late reply. I have forgotten about this article and lately I've trying to write some rough articles about cryptocurrency. Yes it was a fine book. I love python and your book was too advanced for me. I'll try to relearn those things and apply it to some of my fun project(s) now that I only work as a part-timer. Thank you so much again for taking the time to comment. Best of luck my friend! Take care alwasy!

Theory of the Genesis of Bam-e

Well, I was pondering of things today. I mean no things? Like nothing? Can't mine like shit, electricity is down almost every 2 hours so I was wondering to myself... How the hell the name "Bam-e" came to be? As a programmer I need to know the origin of it. Like learning new techniques in programming. I need to dissect things. First off, maybe it's a Tagalog term. I think so. And yeah I found it, or did I. I thought the story goes like this. Someone named Dave came to visit Bam. Here it goes... Dave: Hi, Bam ano yang ginawa mo? Bam: Nagluluto Dave: Yay, maganda yan! Masarap ba yan? Bam: Ah wala, hinalo ko lang ang mga natirang ingredients Dave: Ano name nyan? Bam: Hindi ako sure eh! Dave: Patingin nga? Bam: Sure Dave: Pancit lang naman yan Bam eh! Well, if you don't know tagalog. I'm sorry, I'm not the person to talk to. I'm Bisaya and I'm very bad at tutoring Filipino. The hell, I got 79% when I was in high school. I hate the God ...

Lithium first glimpse

I decided to review my PHP and now I’m interested with the Lithium project. I wanted to get my hands on it just to see what it can do and what are the good stuff in it. Lithium by the way is a PHP web framework, it’s RAD. If you don’t know what a PHP web framework is, I don’t think I can help you. But a Google with the topic can result to many useful resources. I almost forgot most of my PHP background because it’s been 2 years since I coded it. And it was with 4.3 and Oracle. I’m not too sure about what to do next. Instead of installing everything from scratch, I decided to install XAMPP . It’s easy and good stuff (I think). Unlike before, installing PHP and Apache, make Apache recorgnized PHP, add a module to it, install MySQL… You know what I mean. It’s a hassle. But with XAMPP, it’s just a single install and everything is in there. Of course, this doesn’t help if you’re a geek and pretend to know everything and installing everything by hand makes you happy. But for me, it’s fine...
