i have question how change python shell editor. simple example: $python python 2.7.3 (default, aug 1 2012, 05:14:39) [gcc 4.6.3] on linux2 type "help", "copyright", "credits" or "license" more information. >>> import datetime >>> help(datetime) the help() command opens unkonwn editor default. can change make open docs in vim instead? help() should open pager, not editor. sounds environment variables bit mixed up. pager controlled $pager , , if blank use more . should unset it. the default editor, (eg) ipython uses %edit command, can set via $editor variable.

i need natural join on 2 tables named customers , addresses (relationship 1:1), common column in tables key- id (according column natural join operate) . however- column in table customer called "id_customer", , in table addresses it's called- "id". because of that, natural join doesn't work correctly, because program doesn't identify it's same column (by significance). i can not change columns names same (because of many reasons..) there way make work- program understand same columns? so don't use natural join . explicit join instead: from customer c join address on a.id = c.id_customer also, wouldn't surprised if actual join condition were: on a.id_customer = c.id (when using id primary key of tables, practice include table name in foregn reference.) as general rule, natural joins bad choice in long term. might store such queries in stored procedures, triggers, or applications. modifies table s...

one of popular frameworks jquery, there others have lot of community behind them. of dojo books i've found 4+ years old , there seems lot less open source community behind it. sure there lot more ibm's reasons going dojo? ibm uses dojo everywhere (websphere portal, websphere commerce, worklight, bpm, ...). jquery might more popular, doesn't mean it's better. jquery might more open community, has disadvantages. if isn't included in jquery plugins. plugins of jquery never know how long they're going work or how long they're supported. dojo divides dojox library different stages tell how long/well plugin supported. besides better plugin management, dojo has lot more offer makes more complete framework jquery. in opinion, makes dojo toolkit more stable , trustworthy jquery. think dojo more faced towards enterprise community while jquery isn't. ibm delivers lot of software packets/middleware products pointed towards enterprise community t...
