最近在看一个特别古老的美剧《X档案》，特别小的时候断断续续看过一些，记得好像是在中央八电视剧频道演过。在Wiki上这个剧被定义为science fiction horror drama television series，听起来好像挺奇怪的，科幻恐怖剧。看了看还真是挺恐怖的，不知道小时候看这个是不是被吓得够呛。虽然这个剧有点年头了，1993-2002年在FOX电视台播出，但是现在再看剧情和拍摄手法依旧很吸引人，而且正是由于拍摄久远，导致画面很模糊，给这部电视剧添加了一种莫名的神秘感，模模糊糊的画面好像有意遮挡了一些真相，更符合这部剧的风格。
最近出游比较多，五一假期之前的周末随公司去云蒙山爬山，假期去了无锡和苏州，张大夫在南京研究各种花花草草，让人不得不好好热爱了一把生活。其实说起出游，真正让我开始感觉到应该多去走走、体验不一样的生活，是去波兰的克拉科夫Krakow参加2013年的International Conference on Advanced Video and Signal based Surveillance，也是从那个时候开始让我觉得一个人出游的乐趣。在克拉科夫逛了很多地方，感受了当地丰富多彩的文化。因为是自己一个人，所以逛的很惬意，全程都是徒步，累了就在街边的露天餐馆歇一歇，其实就好像咱们国内的大排档，只不过对咱们来说少了烧烤的油烟，多了点小资的味道，喝点汤吃点面包，恢复恢复体力。本想回来好好记录一下这三天在克拉科夫的见闻，一犯懒一晃一年半过去了，记忆也都模糊了，不过能想起来的肯定都是精髓了。
