由Charles L. Bennett, David N. Spergel, 和John N. Bahcall参加
公布了第一批观测结果, 主要成果有三:
1. COBE之后高分辨率全天空的微波背景辐射观测
2. 通过偏振测量确定了较准确的宇宙光子解藕后再次电离时的红移
(也可以大概说成第一批恒星形成的时刻)
3. 宇宙学参数更精确的测量, 和其他途径的观测符合得很好
宇宙年龄137亿年, 误差只有两亿年
MAP标志着宇宙学的确已经进入精确测量阶段了.
附: 最新的一些宇宙学参数 from MAP
总密度参数 Omega_total = 1.02 +/- 0.02
暗能量密度参数 Omega_Lambda = 0.73 +/- 0.04
物质密度参数 Omega_matter = 0.27 +/- 0.04
重子密度参数 Omega_baryon = 0.044 +/- 0.004
原初扰动谱指数 n_s = 0.93 +/- 0.03 (在k=0.05 Mpc^{-1}处)

发帖数: 22 | 3 Thank you for your suggestions.
I use matlab. So, I guess your idea actually is to display these two maps
at a different position along the vertical axis of z, just like that
shown in the attached figure(Suppose the top image is the rainfall
map, while the bottom is the NDVI map), right? |

发帖数: 2 | 4 an interview question from a famed security related company.
a list contains 3 million strings (lengths of strings may vary, 1 to 100)
is there any good hash function to generate keys map to them? collsion
free and the shorter the keys are, the better solution.
note there are existing hashing function like sha1 etc, 1) they
don't gurantee collision free 2) the key they generated are
kind of too long, usually 16 digits
you may say how about incremental integer mapping like
1 maps to first string, |

be coded in map-reduce framework. The whole model implementation could be
done in map-reduce, which is supposed to give you a lot of mileage on data
processing power and speed.
You can check out Mahout, which implements many classical ML models in map-

FP是做不到的，他家一移动就断线，估计tunnel重建需要时间，就是个移动固网。
R+如果能做到能用google map导航，我觉得大家也就不要再渴求了，毕竟是免费的，
语音好几千分钟任打，短信任发，只要服务稳定，网速慢就慢点吧，有wifi的地方再看
youtube也来得及。google map, email, wechat都可以了，免费的还要求什么？ |

以这就是为什么每次开车用FP手机GOOGLE MAP导航总是不行。
R+自然就没这问题啦。有人说offline也可以导航，但是那是手机google map已经缓存
了那部分地图，如果长途开车，google不可能缓存那么多，一旦需要下载地图时就需要
网络了。我的意思就是google map在完全不缓存为前提下，256K足够实时下载地图而且
无延迟否？ |

看看google map，中国平原地区农村
住房占地的确很大
比如我在地图上看着河北附近
大概村落占地：耕地有1：5吧
这样的确比较浪费
美国大概这个比例怎么也得1：100吧
即使人口稠密的法国，
你去google map上去看看
也是一大片农田+很小一个村落。
退房还耕是好事
关键这个事情办完了利益怎么分
不能因为利益分不好而否定整个努力。

这样情况下
Garmin Nuvi 1300LM 4.3" Portable GPS with Lifetime Map Updates $99 shipped
还是Refurbished Garmin Nuvi 255 3.5" Portable GPS Navigator $55?
更贵的型号似乎将来在smartphone人手一个的情况下更没有市场。
同意前面同学讨论的，认路主要是靠脑子。
