Mind maps and Concept maps

Alright y'all.  I am starting to fall in love with the idea of "Concept maps."  Look it up: http://en.wikipedia.org/wiki/Concept_map.  Note how concept maps are better than mind maps: "Concept mapping can be contrasted with the similar idea of mind mapping, which is often restricted to radial hierarchies and tree structures."  Humans simply don't think hierarchically most of the time.  In fact, it's often frustrating to limit thought in such a way.  I've finally found a concept map program that I like: http://cayra.net/.  My sales pitch follows... keep in mind that this took a lot of time (30 secs) copying and pasting to compile this... so take the time to read it!

Cayra is a free desktop application that lets you represent tasks, ideas, concepts and other items in a graphic, well-structured way. Cayra is based on such visualization techniques, as Mind Mapping and Concept Mapping and allows you to conveniently work with big maps.

Cayra's main features: Why should I try it?

You can use Cayra for:

  • Studies
  • Brainstorming
  • Project and people management
  • Planning and organizing
  • Creativity
  • Decision making
  • Problem solving
  • Time management
  • and in many other ways!

Developing a lightweight WebSocket library

Late in 2016, I began development on a lightweight, isomorphic WebSocket library for Node.js called ws-wrapper .  Today, this library is stable and has been successfully used in many production apps. Why?  What about socket.io ?  In my opinion, socket.io and its dependencies are way too heavy .  Now that the year is 2018, this couldn't be more true.  Modern browsers have native WebSocket support meaning that all of the transports built into the socket.io project are just dead weight.  On the other hand, ws-wrapper and its dependencies weigh about 3 KB when minified and gzipped.  Similarly, ws-wrapper consists of about 500 lines of code; whereas, socket.io consists of thousands of lines of code.  As Dijkstra once famously said: "Simplicity is prerequisite for reliability." ws-wrapper also provides a few more features out of the box.  The API exposes a two-way, Promise-based request/response interface.  That is, clients can request dat...

JavaScript Sticky Footer and Scroll Effect

This post talks about two different HTML/JavaScript effects: How to keep a page footer stuck at the bottom of the browser window. How to create a scrolling <div> without using a scroll bar OK. So... you have a website. You want a header stuck at the top of your page and the footer stuck at the bottom of your page. The stuff in the middle, you want to be able to scrollable. But, you don't want those ugly scrollbars to the right of your scrollable text. Maybe, instead, you'll have up arrows and down arrows above and below your <div>. When you mouseover the arrows, the text in the <div> will move up or down and create a scrolling effect. Suppose your page looks like this... <html> <head> <title>Test</title> </head> <body> <div style="position: relative; width: 700px; margin-left: auto; margin-right: auto;"> <div id="header">Header</div> <div id="scrollUp...

Wedding Prediction - October, 2013

Carla and I are planning on getting married sometime in October next year.  We need to pick a date, and that decision may  involve some science and mathematics.  :) For example, we want the weather to be nice.  To be more precise, we'd like the high temperature for the wedding day to be between 60 and 80 degrees Fahrenheit.  Obviously, we have both lived in Ohio our entire lives, and we have a pretty good idea of what the weather will be like.  We both hypothesised that October was a "hit or miss" sort of month; it could be cold, or it could be nice. But, for me, a simple hypothesis was not enough; I really wanted to know the probabilities of decent weather based on historical weather data.  Many websites on the Internet (i.e. almanac.com) charge you to review historical weather data, but Carla and I discovered a cool page on cleveland.com that provided exactly what we wanted.  I loaded the historical temperature data from 1903 to 2011 f...
