I am really really tired of working this way, like a donkey keeping nose on the grind all the time but no time to take care of other more important things in my life. This is definitely NOT what I expected to do, neither I love to do

乔布斯对死亡并不陌生,他曾经经历过事业上的毁灭,也曾经被医生宣布过死期,但是他都走过来了。根据他早年从东方宗教中获得的教授,他也始终有着生死只在呼吸之间的觉悟。甚至是我这样的用户,对于他的死亡也并不陌生,有太多次传出死讯,而我知道那只是时间问题。

真正让人陌生的,是乔布斯之后的世界。

会发生什么事情?还会有iPone5吗?朋友们在通传死讯的时候,也这么问道。我所知道的是,乔布斯的肉体虽然湮灭,但是他在这个世界上会继续存在下去。

辍学者知道乔布斯依然存在,因为乔布斯证明了完备教育并非必备。事业失败者知道乔布斯依然存在,因为乔布斯被自己一手开创的公司开除最终却光荣回归。而对于一切叛经离道的异类们来说,乔布斯提供了难能可贵的个体经验:一个异类无需自我放逐到社会的边缘,却依然有办法让整个人类社会接受他的想法,最重要的是人们不得不承认,这种想法不单是正确的,而且是美的。从而达成一种和解,证明彼此可以共存。

乔布斯的伟大之处并不仅仅局限于他的发明创造,也不局限于他的浴火重生。他最伟大的部分在于如何看待事物,寻求它们的本源。和发明Mac相比,乔布斯重新发明Mp3播放器和手机更能彰显他的个性。在乔布斯动手之前,世界仿佛不过如此。在乔布斯动手之后,人们却觉得世界理应如此。世界原本残缺不全,等放入乔布斯的产品之后,一切完美了许多。便捷如iPod的转盘,顺滑如iPhone的屏幕,世界本应如此。这让人沉溺,也让人醒悟。

无论是凡人、大匠还是宗师,都可以从乔布斯的洞见中有所领会。他的Think different开启心眼,让人在庸常的生活中得以遥望一个不同的世界,并值得毕生努力靠近。

谢谢你,乔布斯!

The difference between Timesten and Oracle in-memory DB option

http://www.rittmanmead.com/2013/09/oracle-openworld-day-2-exalytics-timesten-and-essbase-futures/

And – it actually does make sense. What’s happening is this:

TimesTen’s development team has now been brought under the same management as Oracle Database 12c’s In-Memory option, with (over time) the same core libraries, and same performance features
TimeTen will get the ability to store its tables (which are already held in memory) in columnar format as well as the existing row format – the difference being that unlike the Oracle in-memory feature, this is not done through on-the-fly data replication – it’s either stored row-store or column-store, something you decide when you create the table, and the only thing disk is used for is checkpointing and data persistence between reboots

TimesTen will also gain the ability to be set up as a grid of servers that provide a single database instance – a bit like RAC and it’s single instance/cache fusion, and with support for replication so that you can copy data across the nodes to protect against machine failure. Currently you can link TimesTen servers together but each one is its own database instance, and you’d typically do this for high-availability and failover rather than creating one large database. What this grid setup also gives us though is the ability to do parallel query – Oracle didn’t say whether this would be one slave per grid node, or whether it’d support more than one slave per node, but coupled with the in-memory column store feature, presumably this is going to mean bigger TimesTen databases and a lot faster queries (and it’s fast already).

So what about the positioning of TimesTen vs. Oracle Database In-Memory Option – does one replace the other, or do you use the two together? Oracle’s ideas on this were as follows:

Clearly the in-memory Oracle Database option is going to be a great query accelerator for large-scale data warehouses, but there’s still a lot of value in having a mid-tier in-memory data layer that’s under the control of the BI system owner, rather than the DBAs. You’ll have control over the data model, you can implement it quicker than you’d be able to upgrade the whole data warehouse database, and its physically co-located closer to the BI Server, so you’ll have less of an issue with network latency.
TimesTen’s in-memory columnar storage technology will be based on a similar approach to that which is being taken by the database, and developed by the same overall team. But TimesTen most probably will have shorter development cycles, so new features might appear in TimesTen first, and it’s also lower risk for customers to test out new in-memory approaches in TimesTen rather than trying to reconfigure the whole warehouse to try out a new approach 

And I think this makes sense. Of course, until we actually get hold of the two products and test them out, and see how the pace of development works out over time, we’re not going to fully know which product to deploy where – and of course pricing and packaging has yet to be announced; for example, I’d strongly predict that columnar storage for TimesTen will be an Exalytics-only feature, whilst the In-Memory Option for the database might be priced more like RAC than Partitioning, or even packaged up with Partitioning and OLAP as some sort of “data warehousing option”. We’ll just have to wait and see.

有關甲瑪(位於拉薩河上游的墨竹工卡縣甲瑪鄉,西藏偉大君主松贊干布的故鄉)有礦且被開礦的歷史,可以追溯到全藏地被自稱是恩人的中國共產黨「解放」那時。

1951年-1953年,中國科學院西藏工作隊地質組與毛澤東派往西藏的軍隊一起進入西藏,從昌都地區、怒江流域及藏北湖區、波密及工部地區、拉薩地區​​、雅魯藏布江上游地區等步步深入,繪製地圖,採集標本,標註礦點,得出的結論是「西藏地區的礦產資源是相當豐富的」。 1959年,北京的科學出版社出版《西藏東部地質及礦產調查資料》,這本公開發行的開礦指南為持續半個世紀的、對青藏高原地下資源的瘋狂開發作出了巨大貢獻。

中共體制內的藏人學者降邊嘉措2008年出版的書中披露,1955年,年輕的達賴喇嘛與班禪喇嘛在北京過藏歷新年,毛澤東光臨並直言:「不能只說漢族幫少數民族的忙,少數民族同樣是幫助漢人的。……有些礦產在我們漢人地區是沒有的,但是在你們少數民族地區有。」在《西藏東部地質及礦產調查資料》中,當我讀到「在工作中是把尋找有用礦產放在第一位」時,對「解放西藏」的用心有了深切的感受。

以下,是我在兩年前與了解甲瑪鄉開礦狀況的甲瑪人作的訪談。

(礦場近照)

最早1979年就開礦了,是西藏地質六隊,挖出很多石頭運走了,但不知道發現的是什麼礦,就這樣一直挖到八十年代。

到了九十年代,來了兩個礦業公司,一個公司在甲瑪鄉農民耕種田地的特隆囊建了選礦廠,一個公司在吉曲(拉薩河)旁邊建了選礦廠,當時就已經對河水造成了污染。特隆囊周圍都是山,其中有卓瑪尼徐折吉(二十一度母)神山和烏堅日夏(蓮花山大士法帽)神山,礦業公司在山上蓋了宿舍、後勤辦公室、裝機器炸藥的倉庫等。礦業公司還把一個個礦點承包給小礦廠,大概有六七個礦廠在這裡開採,直到2006年青藏鐵路通車。

2007年,華泰龍礦業公司收購了幾個小礦廠,擴大了挖礦的區域,很多農民的田地被佔用。華泰隆的選礦廠也建在特隆囊,直到現在還在採用,裡面到處都安裝了攝像頭,把守門口的有好幾條大狗。華泰隆還在過去建在拉薩河附近的選礦廠那裡建了水壩,並在水壩對面蓋了房子,從房子下伸出兩根粗大的水管,一直延伸到特隆囊。一個是上水管,一個是排水管,另一頭都伸進拉薩河,也就是說,上水管抽取的是拉薩河的水,排水管則是把選礦廠的污水排入拉薩河。為了掩飾,華泰隆在水管上面蓋了個橋。就這樣,抽水、排水已經三年(至2011年)。每天洗過礦石的污水都排入拉薩河,村民們都議論紛紛,但沒有任何辦法。

華泰隆在兩座山之間 — 此地名叫白囊 — 修了水庫,用以儲存污水。從礦廠挖出的礦石,由車拉到山頂,再往下倒入水庫清洗。而排水管是與蓋在特隆囊的選礦廠連在一起的。水庫的污水滿了之後,就直接流入甲瑪鄉的河水,再流入拉薩河。甲瑪鄉的河叫甲瑪雄曲,原本是當地農牧民唯一的用水河,不光是生活用水,也灌溉田地,餵養牲畜,過去非常清澈。

其實華泰隆蓄污水的水庫是騙人的。曾經有領導們的參觀團帶著記者來了,為了表示開礦沒污染,華泰隆在他們快到之前,把鴨子和魚放進水庫裡,但當參觀團一走,兩三天之後,鴨子和魚全都腐爛了。他們還在礦區內臨時插上花和樹,參觀團走了,花和樹也枯萎了。

甲瑪鄉的鄉幹部、村長等人曾取水去拉薩市防疫站化驗過,結果被測出有三種毒:鉛過量,銅過量,還含有金。防疫站的達瓦啦開了證明,還說水裡含有多種毒,但這三種毒是主要的。證明被帶回放在鄉政府不了了之,現在不知道還在不在。有村民給拉薩市環保局寫信投訴,附上野獸和家畜被毒死的照片,但信和照片都被交給鄉政府了,告狀的人也被警告了。

在華泰隆開礦期間,還有一個礦業公司特在這裡開礦,我們叫它是「上海公司」, 2000年到甲瑪鄉西南面的烏日崗開礦,也建的有工廠和污水庫。後來因為烏日崗的水被污染,與牧民們發生過爭執。上海公司一直挖礦到2010年,然後被中盛礦業公司收購。

中盛公司2005年就在甲瑪探礦,一邊鑽井鑽到很深,一邊注入兌入化學成分的水。聽說這是因為甲瑪礦好,鑽井鑽到幾百公尺就可以立即採礦。

現在甲瑪鄉有兩個大的礦業公司在開礦:一個是華泰隆;一個是中盛。我不知道這兩個公司是不是都屬於中國黃金集團,但華泰隆是屬於中國黃金集團的,比中盛公司大。

中盛公司從甲瑪的西面至南面開礦。在這個區域內有通往桑耶寺的朝聖之門、日松貢布三座神山和名叫措嘎松的聖湖,這個聖湖在傳統上被認為是法王松贊干布的魂湖,堅熱斯(觀世音菩薩)的魂湖。目前挖礦已經挖到魂湖了。

華泰隆是從甲瑪的東面至北面挖過來的。有兩個牧業村、三個農業村為此被強行從山上搬遷下來,如果不搬就抓人,所以不得不搬,上百戶牧民從此失去了水草很好的草場。又因為水污染,曾經三個月內死了一千多頭牲畜,華泰隆只好賠款了328萬元。

被劃在礦區內的還有尼姑寺、蓮花山大士的修行洞、角拉山廟、桑礱山廟、普角山廟、護法神桑拉瑪殿、熱傑嶺寺、承果神泉、貢布山的天葬台,以及岩畫等諸多歷史遺跡,很可惜,如今全都遭到了破壞。

2009年夏天乾旱,華泰龍搶用村民的水,與村民發生衝突,結果甲瑪鄉被軍警包圍。三個月內,五輛特警巡邏車在甲瑪鄉從頭到尾地巡邏,還鳴叫著警報。當時抓了19名村民,部分人被關了幾個月,有的人被關了半年,村長尼瑪次仁被關了一年。其中有好幾個人是被華泰隆十七區和十八區的礦工打傷的,後來送到總醫院,治好後就被關進了監獄。當時華泰隆的老闆對他手下的礦工說:你們就是把這些藏民殺了都沒事,這些藏民什麼都不是,大不了給點錢就擺平了。所以那些礦工都狠勁毆打村民,還放狗來咬,但他們從上到下的確都沒事。

其實村民們沒有說過一句政治的話,說的都是環境被污染,河水被染了毒,老百姓和牲畜的生命都有危險,礦業公司不要來搶村民的水,給我們留下神山聖湖等等。

政府一直都在幫華泰隆和中盛,還派工作組、駐村工作隊到村民家中做思想工作,還拘留了幾個說真話的人。礦業公司也額外給老百姓塞錢,讓他們互相監視告密,嚴防有人上訪。

總之說到底,開礦對我們一點好處都沒有。只對那些官員和老闆有好處,對老百姓沒有什麼好處。

I've been using Xobni for years. It's quite good. Just tried Smartr for iPhone and it's not bad. Help me to find many old mails from some friends whom I have a long time not to contact.

I’m pretty sure none of this would have happened if I hadn’t been fired from Apple. It was awful tasting medicine, but I guess the patient needed it. Sometimes life hits you in the head with a brick. Don’t lose faith. I’m convinced that the only thing that kept me going was that I loved what I did. You’ve got to find what you love. And that is as true for your work as it is for your lovers. Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven’t found it yet, keep looking. Don’t settle. As with all matters of the heart, you’ll know when you find it. And, like any great relationship, it just gets better and better as the years roll on. So keep looking until you find it. Don’t settle.
