One of the most common pieces of advice I received during my study at the university was to leave my comfort zone. You should go try something different, something you feel uncomfortable with. I think this is to some extent a good advice because you are being challenged and therefore,

I recently have a chat with a friend about the possibility to use the subscription model in the retail business. If consumers can predict what they are going to buy in the future, can they pay a deposit in advance in exchange for a lower price? Maybe the sellers are

To be honest, I don’t like meetings. There are mainly two reasons. First, I find it disturbing to switch from one task to another. I would prefer a 4-hour uninterrupted block of time to break it into 1-hour blocks because to make things, for example, an analysis, a program,

I found a very good website summarizing the sanctions against Russia and the countermeasures taken by Russia since early this year. I did want to do the same since whenever I heard the news on sanctions against Russia, they look so familiar, just like those measures are repeating again and

Recently, I have a chat with a friend and we shared some thoughts on NFT with each other. I am getting very busy at work, so I will keep this post short. The essence of Ponzi Scheme is that earlier investors’ profits are paid by funds from more recent investors.

首先，所謂大型的定義是45公斤以上，而所謂家畜的定義是可以在籠裡繁殖，飲食由人類控制，而生存的目的是促進人類主人的生活。 現在的大型家畜其實早在20世紀已經被全部馴化，近代也沒有什麼新的物種被馴化。主要5種物種有綿羊、山羊、牛、豬、馬；次要的九種有單峰駝、雙峰駝、駱馬和羊駝、驢、馴鹿、水牛、犎牛、瓜哇牛、東南亞牛。 為什麼世界上有許多的大型動物，但卻只有14種被馴化？其實不是所有動物都能，或者適合馴化。首先是飲食，大家或許能發現在這14種動物中，他們都是草食的，因為生物質量的轉化效率很低，如果我們要養殖肉食性動物，首先我們要餵草食性動物吃草，再把草食性動物的肉給他們吃，那倒不如直接養草食性動物。第二是，發育速率，大象和大猩猩身上肉很多，但是等他們長大要十多年，不適合馴化。第三是，人工環境中的繁殖困難度，有些動物就是不喜歡在籠子裡繁殖，比如獵豹要在野外追逐的時候才能排卯。第四是，有些動物兇殘，比如大灰熊，非洲水牛，他們都很多肉，但如果要養他們就太危險了。第五是，有些動物比較容易害怕，
