我等了很久，才終於見到 Inside Steve’s Brain 此書的Paperback 現身，當然即買，一看又停不了手。
本書作者Leander Kahney，曾經是美國雜誌老編及記者，又是著名Blogger，Wired Magazine網上版內的Cult of Mac Blog，就係佢老哥搞出來，是不少Mac友愛追的Blog，佢寫過幾本和Apple
Why pickle is not a good way to save your data
On the surface, the (c)Pickle module looks like a good, simple wayfor your Python program to save and load its data; much like XML , it means you don't have to write a parseror even save and load routines as such, just some file and objectmanipulation code. However, through my experience in writing DWiki I'vecome to understand that this temptation would be a mistake (one thatI've actually half-made; DWiki 's caching layer uses pickling)
Some ways to add versioning to pickled objects
To follow on from yesterday's entry , suppose thatone is using (c)Pickle to save data in your Python program, and you wantto version your data somehow. I can think of a number of approaches:
- take the 'pickle as stored JSON' approach; serialize your complexobjects to simple objects (dictionaries, lists, etc), add versionnumbers, and only pickle the simple objects. Then you can do all ofthe usual version mismatch fixups when you de-serialize the reloadedsimple objects
晨早星巴你(四)—其貌不揚吉士包Ugly Coffee Dome
試吃過的多款Starbucks早餐中，這款肯定不是我的最愛，但我的口味並不代表大家的口味，與我同行的幾位女士們，就吃得大叫Yummy Yummy My God Auntie。
但我見這款包肯直認我很醜但我很溫柔，卻又令我產生了憐憫之心，明明不喜歡吃甜包的我，

Sometimes you don't want behavior with your data
I have heard it said that objects are data combined with behavior, whichas a snappy summary strikes me as pretty useful; something like ithas certainly guided me in structuring my programs. (Although I amnowhere nearly as strongly object-oriented as is popular these days; Istill have at least a foot in the procedural programming camp.)
It is also a sensible notion, in the abstract; since data by itself isuseless, so you might as well bundle it together with the code thatunderstands it and
