河北崇礼万龙滑雪场最新雪道一览

十二月 12th, 2009 0 Comments/68 hits

位于河北崇礼万龙滑雪场距离北京250公里,是北京附近最大的滑雪场。明年张承高速崇礼段开通后,从北京到万龙滑雪场将更加方便。

崇礼

 

万龙滑雪场雪道众多。北京郊区的滑雪场难以望其项背。

万龙官方网站还没有放出2009-2010雪季最新的万龙雪道全景图。下面的万龙滑雪场2009-2010雪季雪道全景图(点击可放大)扫描自万龙滑雪场的最新滑雪手册。

与以前的万龙雪道图像对比,可以发现万龙的老板还在继续努力。

万龙以前的雪道一览

到万龙滑雪的人,可能都听说过大奔头。这是大奔头的实景照片。

出发前,别忘了查一下万龙的天气京张高速的路况。回程时,也可以先电话咨询(京张高速管理处值班电话0313-6814195)一下京张高速有没有被大货车堵上。

2009年11月11日,收到Google Wave邀请

据说是google给大家的光棍节礼物。

目前情况下,google wave可能最适合用于小圈子内部交流。

七种武器之供给需求

十一月 10th, 2009 3 Comments/152 hits

影响价格的最根本因素是什么?

影响价格的最直接因素是什么?

答案很简单。

都是供给和需求。

 

关于能源和金属的价格和供需情况,很多人都已经很熟悉了。今天以钾肥为例。

一、供给高度垄断

世界钾盐资源的分布极不平衡,加拿大钾盐储量占世界总量的53%,而我国目前发现总储量仅仅为10亿吨。不到世界总储量的1%。

世界钾肥市场是一个高度垄断的市场。1986年,北美三大钾肥公司组建了卡特尔集团Canpotex,由Canpotex公司统一对外进行价格谈判和签订出口合同。 2005年,白俄钾肥BPC公司开始独家经营该国的钾肥。很快,前苏联地区这几家钾肥公司组建BPC联盟,统一销售。这两大联盟分别占世界钾肥产量的42%和33%。它们之间又进一步联手加强对国际钾肥市场的垄断。与此相对比,欧佩克12个成员国仅控制了全球原油市场的37%。

而全球钾肥的剩余产能更加集中。加拿大Potash公司控制了全球钾肥剩余产能的75%。

二、刚性需求

钾肥是农业不可缺少的三大肥料之一。而且必须来源于钾盐矿,不能人工合成。长期不施钾肥,田地就会减产。

但如果一年不施钾肥,土地减产有限。这个特性可能会增加钾肥的库存效应。在价格过高或者价格预期下跌的时候,各方面库存下降,农民施加钾肥的积极性也下降。比如2008年和2009年。但如果连续几年钾肥施加过少,减产的影响就会不断变大。最后,一旦钾肥价格形成向上预期,各方面库存上升,农民可能也被迫补施钾肥。钾肥需求强烈释放,从而造成钾肥价格的变动可能会比一般商品更加剧烈。

三、定量数据

1、2008年危机以来,所有金属、能源、农产品价格都已经上升,除了钾肥。

Spot US potash prices have drifted down

2、2008年钾肥价格上升过快、过高,2009年钾肥价格一路下跌,导致这两年全球钾肥需求萎缩。这也许预示了2010年钾肥需求的大幅回升。

global potash demand

3、2008/2009年,美国农民一样大幅减少了钾肥的施用。

US potash applications

 

 

结论是什么呢?

1、经过连续一年多的下跌后,钾肥价格下跌空间有限;

2、钾肥相关的投资机会值得关注。

受欢迎的垃圾邮件:来自李连杰壹基金

八月 15th, 2009 2 Comments/26 hits

今天收到的一封垃圾邮件居然来自李连杰壹基金。当然,也可能很久以前在他们的网站注册过,只不过现在突然开始发送邮件而已。

李连杰壹基金给我的主要印象就是两个:

1、开国内慈善基金公开财务信息的先河;

2、始终搞不清楚李连杰本人向壹基金的捐赠有多少。

 

壹基金定期披露财务报告的举动,其实才是壹基金在国内的最大善举。

如果能够引导国内的慈善基金全都接受第三方监督、公开详细的财务报告,善莫大焉。

 

用一个计算器,简单学习了一下李连杰壹基金的最新财务报告。

1

1、收入-支出=结余。(画外音:我晕)

2、收入=货币捐赠收入+实物捐赠收入+其他收入。(画外音:这就是财务分析?我吐)

3、2009年第二季度的其他收入=2007年4月19日至2009年6月30日的其他收入 。(画外音:那又怎么样呢?)

4、只有一个疑惑:这些成千上万的资金产生的财务收入(例如银行存款利息之类)在哪里?

  • 从第3条我们可以知道,其他收入里面肯定不包含财务收入。
  • 难道合并在货币捐赠收入里了?

 

我相信李连杰的基金会是可以信赖的。但是,

  1. 也许壹基金下次披露财务信息时,可以更加详细一点。
  2. 也许壹基金可以将第三方审计人的信息直接在财务报告中明示出来;相信会计师事务所也有爱心,说不定免费帮助壹基金审计。

 

事实上,慈善基金财务公开透明的最大好处,就是所有人都可以发挥监督作用,把事情越做越好,信任越来越深。

如果大家相信自己捐出去的钱确实按照自己 的意愿、流向了被捐赠对象,大家的捐款一定会越来越踊跃。哪怕中国大陆对个人捐赠没有任何税收上的激励。

新加坡华裔李连杰的一小步,希望能成为中国大陆慈善基金业的一大步。

 

来自李连杰壹基金的垃圾邮件,是我收到的唯一受欢迎的垃圾邮件。

爱侃大山(Jaiku@GAE): 类似twitter的微博客

八月 9th, 2009 1 Comments/55 hits

有科学家研究指出,较小的网络圈子,往往可以增强决策能力。太大范围的网络交友圈子反而降低决策的效率。

这种较小的网络圈子应该具备什么样的功能呢:

1、可以很方便地随手写几行,记录自己的随想、所得,方便日后回顾,也方便与朋友交流;

2、很方便对朋友的随想发表评论,产生交互;

3、一个人感兴趣的方面可能很广泛,需要能够对交流的话题进行分类;

4、一个人总有些随想愿意告诉全世界,也总有些随想只愿意与少数朋友共享,为此需要有适当的隐私设置。

好了。上面这些功能,被Google开源的Jaiku都具备了。

GAE上架设了一个Jaiku应用,姑且叫作“爱侃大山(iKanDaShan)”,希望朋友们喜欢。

现在,中场休息。

R与iRex DR1000S电子书阅读器

七月 1st, 2009 1 Comments/81 hits

R是一个开源的统计学软件,iRex DR1000S是第一款10寸屏电子书阅读器(第二款是Amazon刚刚推出的Kindle DX)。它们之间会有什么联系呢?

当然,学习R的过程中,需要阅读很多pdf文件。在10寸屏上阅读这些A4尺寸的pdf文件,比在电脑上阅读或者在那些小尺寸的电子书阅读器上阅读,要轻松多了。但这显然不是今天的重点。

因为iRex DR1000S支持16G存储卡,所以,它的实际作用已经不仅仅是个电子书阅读器,而是电子图书馆。每次看到有用的资料,我都会随手把它保存到硬盘上,然后定期与iRex DR1000S的存储卡进行同步。短短几个月下来,我小小的电子图书馆已经有了好几千份资料、上百个分类目录。任何时候,如果想阅读某个专题方面的资料,进入相应的子目录即可。

但很多时候,关掉电脑,打开iRex DR1000S,只是想读一下最近新搜集到的文档。这就很困难。因为它们分布在上百个分类目录中。iRex DR1000S虽然建立在LINUX系统上,但目前为止,还是没有任何官方或者爱好者提供类似“最新文档列表”的功能。

好了。这时候,好学生、统计博士小R出场了。

花费十几分钟时间,写上几行R代码,解决问题。

只要运行这段R代码,就会将最新的100份文档的快捷方式放到一个专门的目录中。

 

books<-file.info(dir("D:\\Readings",full.names=TRUE,recursive=TRUE))
colnames(books) = c("size", "Dir", "mode", "mtime",    "ctime", "atime")
bs<-books[books$size>1000,c(1,4)]

bs<-bs[order(bs$mtime,decreasing=TRUE),]
bs[,"size"]<-prettyNum(bs[,"size"],scientific=FALSE,big.mark=",")

#create the quick links
ql.path<-"D:/Readings/Work/Latest"
ql.books<-rownames(bs)[1:100]
sapply(ql.books,function(x){
f.name<-basename(x)
f.url<-gsub("D:\\\\Readings","file:../..",x)
ql.file<-file.path(ql.path,paste(f.name,"_001.desktop",sep=""))
ql<-file(ql.file,open="wt",encoding="UTF-8")
writeLines("[Desktop Entry]",ql)
writeLines("Version=1.0",ql)
writeLines("Type=Link",ql)
writeLines(paste("URL=",f.url,sep=""),ql)
writeLines(paste("Name=",f.name,sep=""),ql)
close(ql)
})

 

这段代码的一个小缺憾是,通过R里的list.files函数或者 dir函数可以列出目录中的所有文件名,但是,不含有创建时间等任何文件信息。而file.info函数可以列出文件的创建时间等信息,但又必须提供完全的文件名给它。这样,通过file.info(dir(x))来获取目录下所有文件的名字及其创建时间,实际上对目录内容进行了两次搜索。效率有点偏低。也许还有效率高一点的函数是我所不知道的。

SugarSync:免费的网络备份同步工具

六月 21st, 2009 0 Comments/47 hits

有了Google Docs,Word、EXCEL文档等文档的在线保存、编辑都不成问题。但是,Google Docs不能解决程序代码的同步备份、保存问题。

终于发现了一个完美的方案:SugarSync。集备份、同步、分享于一身。还支持手机和多媒体,支持WIndows和Mac。

SugarSync

SugarSync能让你把台式机、笔记本、手机等不同设备里的文档上传到其集中的“云”资源库里,并且“随时、随地”能把这些文件分享到不同的设备和不同的在线应用上。SugarSync提供的是一个整合的存储和分享服务。通过使用SugarSync,所有的文件和文件夹都可以被家用或办公电脑读取,并且能与同事和家人共享。

免费版本与付费版本的不同点:

  1. 对于免费版本而言,你只能在两台电脑之间备份同步,但付费版本却无此限制。
  2. 免费只能储存每个文件的当前版本和两个历史版本。
  3. 免费版本的上传速度略低于付费版本,但下载速度一样。
  4. 免费空间只有2G。

这样,在移动硬盘备份之外,又多了一个备份。而且,方便在手提电脑和台式机之间同步。

SugarSync安装使用非常简便,三个步骤之后,它就默默在后台同步、备份你指定的文件夹了。

  1. 注册账户;
  2. 下载安装;
  3. 指定需要同步的目录。

虽然是免费版,同步速度还不错。而且因为是程序自动同步,实际上感觉不到免费版速度慢的问题。

 

7月15日前属于免费推广期。期间注册,可以通过引荐获取额外的优惠空间。7月15日之后,奖励减半,250M。

如果想注册尝试一下,建议点击我的这个推荐链接,这样,我们都可以增加500M免费空间。多谢。
