go - Empty function in golang -


this question has answer here:

was looking @ source code go source code, below snippet sleep.go (package time):

package time  // sleep pauses current goroutine @ least duration d. // negative or 0 duration causes sleep return immediately. func sleep(d duration)  // runtimenano returns current value of runtime clock in nanoseconds. func runtimenano() int64

how possible func sleep(d duration) doesn't have implementation? can find exact implementation of sleep function?

edit: answer can found in 2 links provided @davec. please read comments below see explanation why empty function can't replaced go after bootstrapping go (1.5)

considering sleep() (it deschedules golang thread given amount of time), can't express in go, it's implemented kind of compiler instrinsic.

whoa, lots of downvotes here. looks sleep in fact implemented in assembly.

css - SVG using textPath a symbol not rendering in Firefox -

using textpath within symbol doesn't render in firefox. renders fine in latest chrome , ie, when try reference symbol, svg text doesn't render in firefox (37.0.1) - first box appears empty. code below (no external dependencies), there should 2 boxes word test flowing vertically in centre of each. edit: thought issue somehow involved flexbox layout, until paul pointed out issue exists without flexbox layout. the html is: <div> <svg id="not_working" viewbox="0 0 250 1200" preserveaspectratio="xmidymid meet"> <symbol id="test_symbol1" preserveaspectratio="xmidymid meet" viewbox="0 0 250 1200"> <path id="test_symbol_path" d="m 100 1200 l 100 0" /> <text font-size="100" fill="red"> <textpath text-anchor="middle" startoffset="50%" xlink:href="#test_symbol_path...

datatable - Matlab struct computations -

i download data yahoo! finance with: data = getyahoodailydata({'msft', 'axp'},'01/01/2000', '01/01/2015', 'dd/mm/yyyy'); and data stored 1x1 struct. want create tx2 matrix of daily adjusted closing prices msft , axp, column 7 in each table in struct. how can that? or better : there way make computations directly on information/prices in struct? you can access data in struct name. vecmsftadj = data.msft.adjclose; vecaxpadj = data.axp.adjclose; % if want n x 2 matrix madjclose = [vecmsftadj, vecaxpadj]; % personnaly prefer working table tadjclose = table; tadjclose.msftadj = vecmsftadj; tadjclose.axpadj = vecaxpadj;
