Markdown and Pandoc for writing

http://dsoto.github.io/blog/2014/06/12/markdown-and-pandoc-for-writing

Markdown and Pandoc for writing. Thu 12 June 2014. I've been using Markdown, a plain text lightweight markup language in combination with Pandoc, a versatile document converter to do the bulk of my writing. I can use the same text editing tools for my computing work as well as my writing work. It is not straightforward to use references and labels using Markdown. This is important when you need to refer to figures and tables. The lightweight syntax and features of Markdown excel when there will be no pag...

Preparing class materials using Markdown, Github, and Moodle

http://dsoto.github.io/blog/2014/11/03/preparing-class-materials-using-markdown-github-and-moodle

Preparing class materials using Markdown, Github, and Moodle. Mon 03 November 2014. A few months ago, I wrote about the way I use Markdown, a simple syntax for content generation in my writing and teaching. In this post, I document how I use Moodle, Github, and Dexy to easily update and publish materials for my class. I've been sharing my syllabus electronically like this for a while now, but I've started linking to other materials as well. Posted by Daniel Soto. Mon 03 November 2014.

Refrigeration cost of conserved energy

http://dsoto.github.io/blog/2013/10/10/refrigeration-cost-of-conserved-energy

Refrigeration cost of conserved energy. Thu 10 October 2013. Typical refrigerators in rural environments with photovoltaic electricity tend to strain the inverters. There are some very energy efficient refrigerator models as well but the cost for these units is much higher. We compare between two representative refrigerators. A typical refrigerator is the Haier, which is basically what we in the states might call a dorm room refrigerator. 821 wh per day. Freezer 280 wh per day at 32C. Energy kWh per day.

First post with Pelican. Thu 10 October 2013. I am trying out pelican as an authoring tool. I cloned the octopress pelican theme and added to the pelicanconf file. I cloned jakevdp's plugins and checked out the liquid tags import branch and linked using pelicanconf. This is to support ipython notebooks in the blog. Read On ↵. First Week of Teaching.

Equivalent APR of M-KOPA Financing

http://dsoto.github.io/blog/2014/06/16/equivalent-apr-of-m-kopa-financing

Equivalent APR of M-KOPA Financing. Mon 16 June 2014. Many customers are unable to purchase solar home systems for lighting and phone charging without a financing option. For a customer to compare between the rate available from a microfinance lender and a company that provides in-house finance, they must compare the effective interest rates. M-KOPA advertises their deposit and daily payments online and the effective APR can be calculated from this. Calculate APR as range. Initial payment = {} KSH. I can...

Energy cost of beverage cooling

http://dsoto.github.io/blog/2013/10/10/energy-cost-of-beverage-cooling

Energy cost of beverage cooling. Thu 10 October 2013. Here I calculate the energy needed to cool a beverage. I also estimate the cost of this energy. I start by calculating the sensible heat that must be extracted from a can or bottle. Density water g per l. Heat capacity water J gK. Density water g per l. Heat capacity water J gK. Sensible heat (joules) =. Sensible heat (kWh) =. Sensible heat (joules) = 52318.75 sensible heat (kWh) = 0.015. Refrigerator energy use as stated on product sheet. This work i...

Refrigeration lifecycle costs and insulation thickness

http://dsoto.github.io/blog/2013/10/18/refrigeration-lifecycle-costs-and-insulation-thickness

Refrigeration lifecycle costs and insulation thickness. Fri 18 October 2013. These calculations estimate the optimal thickness of insulation for a simplified refrigerator model. The life-cycle cost considers both the first cost of purchasing insulation and the operational cost of buying electricity to power the refrigerator. We assume that the other costs (exterior, compressor, etc.) are fixed with the insulation thickness and therefore do not affect the optimum thickness. Cost for polyurethane spray foam.
