ERROR: MethodError: `convert` has no method matching convert(::Type{Float64}, ::UTF8String)
This may have arisen from a call to the constructor Float64(...),
since type constructors fall back to convert methods.
Closest candidates are:
call{T}(::Type{T}, ::Any)
convert(::Type{Float64}, ::Int8)
convert(::Type{Float64}, ::Int16)
...
in call at essentials.jl:56

Wasn't this list locked for new posts? Maybe there's something wrong with the configuration.
Sorry, I meant new threads.
