i have stored pdf , want display in iframe. appropriate way calculate src? i used did not work me: <set field="resourcereference" from="ec.resource.getlocationreference('dbresource://mantle/content/cv/100000/content_100006/161107_hs.pdf')"/> then, in html added: src="${resourcereference.geturl()}" without success. a url resourcereference internal url (starting dbresource:// in example) , not valid url web client. you'll need add screen transition or streams file web client (using ec.web.sendresourceresponse(string location) method). there various examples of transitions using method in framework, simplescreens, etc.

i can use module(scipy.optimize.least_squares) 1-d curve fitting(of course,i can use curve_fit module directly) , this def f(par,data,obs): return par[0]*data+par[1]-obs def get_f(x,a,b): return x*a+b data = np.linspace(0, 50, 100) obs = get_f(data,3.2,2.3) par = np.array([1.0, 1.0]) res_lsq = least_squares(f, par, args=(data, obs)) print res_lsq.x i can right fitting parameter (3.2,2.3),but when generalize method multi-dimension,like this def f(par,data,obs): return par[0]*data[0,:]+par[1]*data[1,:]-obs def get_f(x,a,b): return x[0]*a+b*x[1] data = np.asarray((np.linspace(0, 50, 100),(np.linspace(0, 50, 100)) ) ) obs = get_f(data,1.,1.) par = np.array([3.0, 5.0]) res_lsq = least_squares(f, par, args=(data, obs)) print res_lsq.x i find can not right answer, i.e (1.,1.)，i have no idea whether have made mistake. the way generate data , observations in "multi-dimensional" case results in get_f returning (a+b)*x[0] (input values x[0] , x[1]

i'm trying insert qsqlrecord in empty table. field isptzonvif defined as: isptzonvif bool not null default false but following error: failed submit. column 'isptzonvif' cannot null qmysql3: unable execute statement if print contents of record before trying insert get: qsqlrecord( 27 ) " 0:" qsqlfield("id", uint, length: 10, precision: 0, required: yes, generated: yes, typeid: 3) "-1" " 1:" qsqlfield("host", qstring, length: 150, precision: 0, required: no, generated: yes, typeid: 253) "" " 2:" qsqlfield("port", uint, length: 10, precision: 0, required: no, generated: yes, typeid: 3) "0" ... " 7:" qsqlfield("isptzonvif", int, length: 1, precision: 0, required: yes, generated: yes, typeid: 1) "0" ... i cannot image happening here because isptzonvif has default value (represented 0 "0"). i'm using qt4

there lots of possibilities not solved problem yet. first tried use phonegap not anymore because of indexeddb problems. want call native application can read barcode web app , use data eventually. couldn't figure out , appreciate if can explain have looked @ barcode scanning in web apps smartphone/tablet browsers , how open native ios app web app . many in advance.

is possible create repeating pattern of uneven columns using nth-child? have, works first row: .three-cols > div:nth-child(1n) { width: 50%; } .three-cols > div:nth-child(2n) { width: 25%; } .three-cols > div:nth-child(3n) { width: 25%; } .three-cols > div:nth-child(3n) { margin-right: 0; } so want every row split:50%,25%,25% http://codepen.io/garethj/pen/knpqyd there 3 items per row need use 3n each selector. offset 1, 2 or 3 depending on element wish target: .three-cols > div:nth-child(3n+1) { width: 50%; } .three-cols > div:nth-child(3n+2) { width: 25%; } .three-cols > div:nth-child(3n+3) { width: 25%; } .three-cols > div:nth-child(3n+3) { margin-right: 0; } .block { overflow: hidden; } .block > div { box-sizing: border-box; float: left; border: 3px solid purple; } <footer> <div class="block three-cols"> <div>50%</div> <div>25%
