Tmux is an open-source terminal multiplexr for Unix-like operating systems. It allows multiple terminal sessions to be accessed simultaneously in a single window.

Graph is common data structure that represents the relationships between different entities using edges and vertices. The behavior of search algorithm can be changed by plugging in different data structures, such as using a stack yields depth-first search, and using a queue gives breadth-first search.

"Graph theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects. A graph in this context is made up of vertices (also called nodes or points) which are connected by edges (also called links or lines). Graphs are one of the principal objects of study in discrete mathematics." ... from Wiki page.

Either computer data storage or telecommunication, regardless of the data storages and transmission, is non-zero probabilities that the data could be changed while it's being stored or transmitted. There is always a code-word with block length without free bit-errors. That means the data probably could be changed while it is being processed or transmitted. If the machine can't locate the position of the error and correct it, the information might be lost forever.

The HTML canvas can be used for sketching/drawing either by mouse or by touch. In the previous post, I quickly discuss how to use Canvas API to implement a canvas with mouse sketching. In this post, I would like to describe how go about implementing for sketching/drawing by mouse and touch.

這週末來到位於新竹縣新埔鎮的飛龍池登山步道輕鬆健行。這區域內的步道蜿蜒圍繞著山區，古道串連著龍頭公園、忘憂谷、運動公園、三聖宮、採茶古道....。從新竹高鐵區開車到這，距離不遠，人潮也沒有很多，幽靜宜人，而且該區域並不需要申請以及預約即可進入，所以適合週末安排的時段前來健行。

The HTML canvas can be used for sketching/drawing by mouse. The canvas API provides a means for drawing graphics via JavaScript and the HTML element. It largely focuses on 2D graphics. In this post, I would like to describe how to quickly go about implementing this.

"After going on your life-changing journey, you now realize that you don’t want what you thought you wanted. What you really wanted was inside you all along."

In our daily life, most of us usually use Google Map or Apple Maps to help us to navigate to a place. We can see traffic info, public transit and also choose our mode of transportation.
