phantomjs --web-security=no -

-
in documentation phantomjs, there option turn off web security , allow xhr (cross domain requests). does present security risk user if filling forms credentials such usernames , passwords , downloading screenshots casper/phantom? maybe. allowing cross domain xhr opens few attacks. e.g. see https://stackoverflow.com/a/7615287/841830 . see is cors secure way cross-domain ajax requests? but tends not come normal use cases phantom: whether testing own web site, or screen-scraping, tend go pre-decided urls , links, , not sending secret information, , not going tricked new , suspicious link. unlikely logged bank, or facebook, while testing site or scraping google search results. (but, if scraping google pages force sign google first, bit more careful - perhaps set dedicated gmail account scraping.) so, in summary, attacks bit more obscure , unlikely, compared normal desktop browsing session, still there, use --web-security=no when script otherwise not work.

postgresql - Should index include a 'constant' column? -

-
i doing partitioning in postgres db. root table kpis_weekly(date, personid, metric, value) , partition table kpis_weekly_yyyymmdd inherits kpis_weekly table. set primary key of child table (personid, metric), date same in same partition table. is right practice? or should create primary key on (date, personid, metric), although date 'constant' inside same partition table. the queries run on table like: select * kpis_weekly date = '2011-02-20' , personid = 50 select * kpis_weekly date = '2011-02-20' , metric = 'centrality' , personid in ( 50, 82, 10, 14, 22, 36) if pair personid - metric unique yes, it's better have primary key based on these 2 columns. in case primary key of master table cannot propagated child tables, including date key useless.

bash - awk unmatched with blank file -

-
recently i've encountered strange behavioral problem awk say have 2 files 1 blank file & populated data so let me apply simple unmatched code awk -v var=0 'nr==fnr{a[$var]++;next} !($var in a)' file1 file2 say file1 & file 2 b v it return blank data supposed return content in file 2. can explain me how overcome issue? there isn't data in file1 , overall record number never changes, fnr == nr throughout file2 . i'm not sure there's easy way fix that, either. you can't use begin block record current file name , spot when file name changes. posix specification awk says: filename pathname of current input file. inside begin action value undefined. inside end action value shall name of last input file processed. i think best bet comparing filename argv[1] : awk -v var=0 'filename==argv[1] {a[$var]++;next} !($var in a)' file1 file2

my problem can seen here if zoom 110% or more on browser. (it happens chrome, i'm not sure other browsers). basically, on right side can see grey sliver of few pixels after 'contact' button when zoom in. i'm assuming because have buttons set there amount of blue area around each word, , gets messed when zoom. wondering if there way keep button-size formatting default fill space when zoomed in. hope makes sense. html: <body> <div id="wrapper"> <div id="container"> <nav> <div id="navigation"> <ul> <li><a href="index.html">home</a></li><li><a href="about.html">about</a></li><li><a href="milk.html">milk</a></li><li><a href="farm.html">the farm</a></li><li><a href="contact.html">contact</a></li> </...

rust - How can I sort a LinkedList with just the standard library? -

-
vec provides sort method (through deref implementation), linkedlist not. there generic algorithm somewhere in rust standard library allows sorting of linkedlist s? i don't think there built-in way it. however, can move list contents vec , sort , turn linked list: let mut vec: vec<_> = list.into_iter().collect(); vec.sort(); let list: linkedlist<_> = vec.into_iter().collect(); this idea not remotely bad may seem - see here . while relatively fast algorithms sorting linked list do exist, won't give of cache performance flat array sorting may do.

python - enter the correct number of variables based on function handle -

i have list of variables, , function object , assign correct number of variable depending on function. def sum2(x,y): return x + y def sum3(x,y,z): return x + y + z varlist = [1,2,3] so if f = sum2 , call first 2 elements of varlist, , if f = sum3 , call 3 elements of function. use inspect module follows: import inspect n2 = len(inspect.getargspec(sum2)[0]) n3 = len(inspect.getargspec(sum3)[0]) sum2(*varlist[0:n2]) sum3(*varlist[0:n3]) getargspec returns 4-tuple of (args, varargs, keywords, defaults) . above code works if args explicit, i.e. not * or ** args. if have of those, change code accordingly.
