possible duplicate: count(*) vs count(1) if have table, 'id' primary key, these 2 commands have different performance ? select count(*) t; select count(id) t; thanks these have same performance. in databases, count() results in scan of table or available indexes. whether or not uses index instead of table depends on query optimizer. if optimizer smart enough use index, should smart enough in both cases. using available metadata tables, can number of rows in table mroe efficiently using count() query.

i have large edge list, , plot edges have particular weight, how can that? i have far tried plot.graph(e(sgdf)[e(sgdf)$weight==3])) but error error in v(g) : not graph object copy graph first, remove edges don't need, , plot rest: > sgdf.copy <- delete.edges(sgdf, which(e(sgdf)$weight != 3)-1) > plot(sgdf.copy) the -1 needed in delete.edges because igraph uses zero-based edge indices while r uses 1-based indices. update : anonymous editor (whose edit sadly rejected) pointed out, igraph uses 1-base edge indices igraph 0.6 onwards. therefore, subtract 1 if using igraph 0.5.x or earlier.

i've got simple makefile in 1 target depends on library: test49: test49.c -lpthread the binary built using implicit rule turning .c file executable. problem is, trying cross-compile, make interpreting -lpthread pointing /usr/lib/libpthread.so , quite incorrect. have defined path cross-compiler using cc=/path/to/bin/gcc , assume figure out -lpthread should somewhere in /path/to/lib , not. you replace test49: test49.c -lpthread with test49: test49.c /path/to/lib/lpthread.so

at internship, tasked setting whatever php shopping cart me , co workers think best. installed magento, , looks nice, develops own mysql database. that's not bad thing, job invested lot of time in implementing system automatically synchronizes mysql database quickbooks data. database has 1300+ items in , ready go. magento forums saying magento stuck it's own database. is there solution this? can magento community modified works database in place? or there php mysql shopping cart out there can work item/customer database that's in place? unless company has invested gigantic amounts of money build current system, , unless it's heavily customized, may profit admitting possible might have gone in wrong direction in trying build wheel has been re-invented many times already. i've never used magento, quick google search shows have quickbooks support , , i'm sure quick import script solve ~1300 items have added system.

the introduction of @font-face in css3 allows web designers use fonts same across browsers. thought until trying out following code in jsfiddle : html : <div> the_quick_brown<br> fox_jumps_over<br> the_lazy_dog </div> css : @font-face { font-family: 'open sans'; font-style: normal; font-weight: 400; src: url('http://themes.googleusercontent.com/static/fonts/opensans/v6/cjzkeoubrn4kerxqtauh3t8e0i7kzn-epnyo3hzu7kw.woff') format('woff'); } div { display: block; width: 496px; height: 86px; font-size: 1.3em; font-family: 'open sans'; font-style: normal; margin: 0; border: 0; padding: 0; background: cyan; letter-spacing: 1.44em; line-height: 1.44; overflow: hidden; } this view firefox 12.0. take note of partially obscured 'o' in 'brown', position of 'g' in 'dog' , underscore '_' @ bottom edge. this view go...

at first thought arr.slice(0) doing deep unreferenced copy, doing shallow unreferenced copy, if array contains nested arrays, they still referenced : var = [1,2] var b = [3,4] var c = [a,b] var d = c.slice(0) d[0] === // true, means /same/ object d[0][0] = "hi!" // ["hi!", 2] (example source) the solution on links provided easy when know structure of array (just .slice(0) ing again nested arrays trick), gets complicated if don't know how structure of nested arrays is. my first idea loop on whole thing, on levels, until fails find array object. is approach acceptable? are there built-in functions missing? i can't believe need copying silly array like nonnb suggests, serializations / deserialization cycle result in deep copy. this: //a array arbitrary levels of nesting. var c = json.parse(json.stringify(a));
