Improve performance of SVG/CSS spinner -

-

i'm replacing old gif spinner of ember.js app new svg/css spinner.

this spinner, on project saved .svg:

http://codepen.io/fezvrasta/pen/pjxovm

and load css:

background:       no-repeat center; background-image: url(../images/spinner.svg); background-size:  65px 65px;

the problem ember.js application lot of calculations while spinner being shown , makes spinner lag.

i have tried encoding svg in base64 using b64.io gain loading time, performance same.

as can see tried use gpu using rotate3d instead of rotate, didn't performance boost.

any advice improve fluidity of it? practices, tricks, , on welcome.

the problem here lies ember.js app, not spinner.

i’d try familiarising profiling tools figure out in ember app causes lagging. i’m sure there steps can take improve performance of app!

mysql - FireDac error 314 - but DLLs are in program directory -

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.

-
so per documentation https://developer.github.com/v3/repos/releases/#list-releases-for-a-repository get /repos/:owner/:repo/releases should list relases , https://api.github.com/repos/jquery/jquery/releases should list releases in jquery project , not , why ? because repository doesn't have releases. has tags github presenting in releases page. for more clear example, see: https://github.com/hashicorp/terraform/releases which has both releases , tags showing on page, api shows releases: https://api.github.com/repos/hashicorp/terraform/releases
