手術到今天剛好滿三個月,這個禮拜要再去醫院追蹤檢查。目前,左腳因為神經根引起的周邊神經病變(感覺異常:麻、刺、脹)已經消退很多,主觀來說,異常的感覺大約剩下原來的兩成左右,左腿的肌力和髖關節的活動度差不多完全恢復了。除了穿著背袈很熱之外,日常行動還算自如,長時間活動起來也不會太疲累了。

事發至今,一切都算是順利,真是要感謝太多人。現場照顧及送我到醫院的傘友、基隆長庚的急診醫師、國泰的醫師和護理師、幫我針灸的胡醫師、來探望我及替我打氣祝福的親朋好友,還有最辛苦的家人。事故之初,因為擔心保理賠險會有疑慮,所以比較低調,不願多提,還請大家見諒。

時間倒轉到三個月前。 Continue Reading →

Really, I hate reinventing wheels.  but sometimes there are just rectangular ones available.

While I am busy getting married, I plan to write a series of articles on automated trading, for the stuff I built over the past few years to distract myself from the stress.  I do plan to open source all the infrastructure code after cleaning them up.  Here’s the first module: Finance::FITF.

It’s really more a format than a library, and a very simple one.  But there just aren’t anything openly available i can find.  The idea is to provide efficient storage for both aggregated (the typical OHLC content) as well as tick data when you want to do more fine-grained back testing or statistics.  The aggregated data entry has an index pointing to the start of the tick data in the corresponding time period, so you can seek there and just run through just the part of the ticks data you need.

I just created a public ec2 image (ami-06225c54 in ap-southeast-1 region).

If you are unfortunate enough and have to test something on win32, here’s the saviour.  Just launch this image, which has strawberry perl 5.12 (with awesome cpanminus & par), copssh, git, and vc# express 2008 installed.

you can use ec2-get-password -k <lauchkey> to get the password for Administrator, and just use ssh into it, having authorized port 22.  beware that new win32 instances take 15-20 min to generate admin password, for whatever reasons.

happy camelclouding!
