问题

现在搭建一个博客非常容易，但是很少有人关注技术博客应该怎么写。

通常来说，技术博客容易出现以下的问题：

• 内容篇幅太短，没有介绍问题的上下文环境，难以获得共鸣。
• 内容篇幅太长，从头到尾解释每一个细节，没有突出核心问题。
• 维护博客花费大量时间却没有得到相应的反馈，久而久之失去写作动力。

技术博客作为一种写作，是需要指引和练习的。那么是否有一份适合技术博客的写作指引呢？

Mr. James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst. Pinhurst is only five miles from Silbury, but Mr. Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinburst to Silbury. The bird covered the distance in three minutes. Up to now, Mr. Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private ‘telephone’ service.

I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.

Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter taught me a few words of Italian. Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card!

It was Sunday. I never get up early on Sundays. I sometimes stay in bed until lunchtime. Last Sunday I got up very late. I looked out of the window. It was dark outside. ‘What a day!’ I thought. ‘It’s raining again.’ Just then, the telephone rang. It was my aunt Lucy. ‘I’ve just arrived by train,’ she said. ‘I’m coming to see you.’

‘But I’m still having breakfast,’ I said.

‘What are you doing?’ she asked.

‘I’m having breakfast,’ I repeated.

‘Dear me,’ she said. ‘Do you always get up so late? It’s one o’clock!’

Last week I went to the theatre. I had a very good seat. The play was very interesting. I did not enjoy it. A young man and a young woman were sitting behind me. They were talking loudly. I got very angry. I could not hear the actors. I turned round. I looked at the man and the woman angrily. They did not pay any attention. In the end, I could not bear it. I turned round again. ‘I can’t hear a word!’ I said angrily.

‘It’s none of your business,’ the young man said rudely. ‘This is a private conversation!’
