r - RAdwords error ("server certificate verification failed") -

-

when run following code involving radwords package, error seems related certificates. there simple solution this?

library(radwords) google_auth <- doauth()

error in function (type, msg, aserror = true) : server certificate verification failed. cafile: /home/pavel/r/x86_64-pc-linux-gnu-library/3.2/rcurl/curlssl/ca-bundle.crt crlfile: none

the error occurs on ubuntu 14.04, r 3.2.0, rcurl 1.95-4.5, , radwords 0.1.4.

i had same issue on ubuntu 14.04, manually downloading (and overriding rcurl shipped version of) cacert.pem curl homepage resolved issue. know it's ugly workaround :)

java - UML - How would you draw a try catch in a sequence diagram? -

Image
is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
