Fun: Places I hiked before (Qingkai's Hiking Map)

I love hiking, and before we had our kids, we usually go hiking or camping every weekend. Even with our daughter, we still try to go out every weekend with her on my back. We once had an ambitious plan to hike in all the parks in Bay Area before I graduate,  but now it seems hard to achieve the goal!


In the following, I plot all my hiked places in Bay Area (Plus some in Northern CA) on a map, and many places we went more than once! I am really impressed by how many places we visited in the last few years, and hope we will increase more hiking dots on the map.

Tricks: How to search in Gmails

Many times we need to search some emails in the Gmail, but instead of simply searching for a name or key word, there are many useful tricks in Gmail that can save you a lot of time. Here are some of the tricks I use all the time for search in my life. 

Using different operators

  • Finding emails with Obama in subject line
subject:Obama
  • Finding the unread emails from Obama with attachment that emails
is:unread from:Obama has:attachment
  • Finding emails larger than 10 MB in size: 
size:10MB
  • Finding emails larger than 5 MB and smaller than 10 MB in size: 
larger_than:5m smaller_than:10M 
  • Finding emails larger than 5 MB and older than 1 year
larger:5m older_than:1y
  • Finding emails with word document as the attachment
filename:.doc
  • Finding all the emails with attachment in drafts
in:drafts has:attachment 
  • Finding emails between two dates
after:2011/08/22 before:2011/08/31 

Combining operators

By default, Gmail combines with multiple operators with 'AND', for example, the above one is finding the emails after 2011/08/22 AND 2011/08/31. But there are more options:
  • Search exact phrase
"good day"
Note that, if you search only for good day, you will get results from emails contain both good and day in them, but they may not contain good day phrase. 
  • Search emails containing either Iron man OR Spider man
"Iron man" OR "Spider man"
  • Search emails not containing day but have good in it
good -day
  • Search emails have dinner and movie in the subject line
subject:(dinner movie)
This will find emails have both dinner and movie in the subject line, but they are maybe not a phrase.
