My phone was dropped to the toilet!!! :(

  • Tim Tim

Yesterday, I accidentally dropped my phone to the toilet. I was not panic, what I did was washing it, washing it and washing it. Like I washed GoPro before. However, I found it did not work well after that, the screen behave weird, it goes to black randomly. What I did after I did some researching online to find what is a good way to get the water out of the phone. Rice I did have rice, but in my mind, I thought it should be fine, so I leave it and put my phone close the dehumidifier, the phone and the case both looked very dry after about 1 hour. I can turn on the phone then, but the screen goes off randomly. 😂 So I left the phone there for a whole night, until the morning alarm (the alarm wakes the phone up automatically). It did not get better, and I knew I should buy a new phone. Buy a Phone in New Zealand Lineage OS is my favorite, so my options are limited. Not buy the newest,… Read More »My phone was dropped to the toilet!!! 🙁

How much benefits through multi-process and NodeJs child_process?

  • Tim Tim

When programming, is it a good idea to use multi-process all the time? Does NodeJs child_process is a good way to empower your machine power? The answer is not awalys. For light load, the time consumed to start a new process is much heavier than the load it self, we should not spawn multi process. And the decreasing of time-spending is not linear with process count increasing. About The process spawning is through NodeJs Child Process. Testing Machine and Work Load The work load to sum 10k numbers and repeat the work from 1 to 100k times. The spec is 6 Core Intel CPU with 16G ram. Use Single Process for Light Work Load As we can find from the diagram, by using single process which is only one main process, for the light work which is less than 10k * 1k plus, the single process is the best solution. Spawning multiple process can only make it more time consuming. For the work 10k * 1, the single process takes less than 1 ms, but after spawning process, it takes… Read More »How much benefits through multi-process and NodeJs child_process?

How to generate markdown through Jinja2?

Recently, when I build PocketToWordpress. I really need a tool to convert HTML string to Markdown string, however none of them work perfectly, some shortages I found. None of them can handle indents well, indents in markdown will be code block, but in html, it does nothing. They cannot handle <a> with nofollow or new tab. The solution I found for solving this problem is using Jinja2. Jinja2 as a powerful rendering engine is usually used to generate HTML content, such as in Flask/Django frameworks, however, we can used it for markdown too. How to use Jinja2 generate markdown? The easiest way to generate markdown will be using string formatting, something like in Python. If giving up HTML tags, Jinja2 will became a powerful string format-er too.
