该离开的都走了，独自一人蒸馏着黑暗，直到让自己湮灭在无尽的黑暗中……
去年八月从Upper Yosemite Falls Trailhead出发去Eagle Peak backpacking的时候，我用的很多装备都是七八年以前购买的，其中背包Kelty Tornado 4200甚至是十几年前我在国内买的。虽然用了十几年但也没什么大问题，唯一的问题就是比较重。
最近半年计划了一条5天的线路（之后再详细讲一讲），这样就需要携带很多食品，加上去年所使用的装备，怕是40 lb都搞不定。于是大概在二三月份的时候，开始盘算着把过去几年攒下的旧装备慢慢进行轻量化升级。

Camping in the wilderness of Yosemite NP requires a permit. I already reserved a permit for 2 people from June 18 (Tue.) to June 22 (Saturday., can be changed), for Glacier Point – Little Yosemite Valley trailhead, which is also eligible for Half Dome hiking. It needs to be picked up from the office on June 17. Please see below for more details. And also, we need to follow the wilderness regulation of Yosemite NP. Few important points:

The reason the early developers at OpenCV chose BGR color format is that back then BGR color format was popular among camera manufacturers and software providers. E.g. in Windows, when specifying color value using COLORREF they use the BGR format 0x00bbggrr.
BGR was a choice made for historical reasons and now we have to live with it. In other words, BGR is the horse’s ass in OpenCV.
This post is a tutorial for digital camera calibration on macOS Sonoma 14 with open source tools. I followed this article on RawTherapee website, but made some modification based on changes in new operating system.
Why not just using the software from the vendor to do this? So far some of the software like the ColorChecker Camera Calibration only generate a 173B *.dcp file from the DNG raw file, which looks very fishy.

总得来说，各方面都要比Cancún差一些。当年麦哲伦通过麦哲伦海峡到达太平洋时觉得风平浪静，是相对于南大西洋惊涛骇浪来说的。太平洋跟太平其实没有什么关系，跟加勒比海相比，完全就是惊涛骇浪。酒店后边的海滩虽然已经是Cortez Sea，但依然风浪巨大完全没有办法下海游泳。
但这还不是最惨的。酒店不知是何缘故所有游泳池都没有加热，偌大的游泳池里只有寥寥几个人；唯一加热的Jacuzzi里挨挨挤挤十几个人……
总体来说吃得还不错，Taco尤其好吃。Cocktail比较黑心，很多基本都是糖水，完全没什么酒味，喝到血糖爆炸都没什么感觉。
