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!

Restoring .dat data to MSSQL

This is just a document in case I forgot to restore data files to MSSQL. I had this problem before when a colleague gave me a .dat files to be restored to SQL server. I had a 2008 version of the server and had no trouble restoring it. The problem is, I forgot how I did it when I had a new PC and I upgraded it to 2012 SQL server. But this is a simple task (although I had a full day remembering how I did it and I had no luck finding the solution from google). First off, click restore, like so I had trouble with the database whether or not to add a new database and restore the file to it, or not. Simple answer is no need. With the next image you can see that the configuration is very simple. Just set it to device as the source and find the .mdf file. It automatically displays a suggestion for the database name and you're done. Click OK and wait a couple of minutes for SQL server to restore the data. [EDIT] In case you are restoring a backup file without an extension. You c...

Setting Up IIS on a Local Network: A Developer's Journey

Today, I embarked on a mission to set up an IIS server on our local network. The primary objective? To create local network versions of our applications for testing and development purposes. Additionally, we're in the process of setting up a CI/CD server to automate our workflows. However, like many journeys, this one had its share of hurdles. The initial hiccup arose when I realized that .NET was installed before IIS, leading to compatibility issues. Despite attempting to install IIS through the control panel and tweaking .NET components, the problem persisted. "Nada." After some trial and error, a breakthrough emerged. The solution? Executing dism as an Administrator in the C:\Windows\Microsoft.NET\Framework\v4.0.30319 directory: \> dism /online /enable-feature /featurename:IIS-ASPNET45 /all And just like that, the clouds parted, and the path forward became clear. With IIS up and running seamlessly, our developers rejoiced, and testing commenced with renewed vigor. H...
