[julia-users] Crashing while parsing large XML file

I'm parsing an XML file that's about 30gb and wrote the loop below to parse it line by line. My code cycles through each line and builds a 1x200 dataframe that is appended to a larger dataframe. When the larger dataframe gets to 1000 rows I stream it to an SQLite table. The code works for the

Michela, would you mind posting these questions on the julia-opt list since that's a specific list for optimization? On Thu, Jan 28, 2016 at 10:14 AM, Michela Di Lullo < michela.dilu...@uniroma1.it> wrote: > Hello, > > does anyone know how to get the gurobi log on a txt file when using julia? >

Hello, does anyone know how to get the gurobi log on a txt file when using julia? Thanks for any suggestion, Michela

Re: [julia-users] Create local function variables programmatically from a dictionnary

Reifying local scopes is a feature that dynamic languages often allow as an artifact of the most obvious implementation of scopes in low-performance interpreters: as dictionaries from symbols to values. Exposing this, however, effectively prevents any other possible implementation. In particular,

Also check out Ito.jl and TimeZones.jl. It seems that both Ito.jl and BusinessDays.jl are geared towards bond trading, so I'm not sure how well they work for general queries. If you find you have opinions about the strengths/weaknesses of any of these packages, please post here! On Thu, Jan 28,

No real reason. I was going back and forth between eachline(f) and for i = 1:n to see if it worked for 1000 rows, then 10,000 rows, etc. I ended up with a hybrid of the two. Will that matter much? On Thursday, January 28, 2016 at 1:32:09 PM UTC-5, Diego Javier Zea wrote: > > Hi! > > Why you

At best, you'll only see every other line, right? At worst, eachline may do some IO lookahead (i.e. read one line ahead) and this will do something even more confusing. On Thu, Jan 28, 2016 at 3:35 PM, Brandon Booth wrote: > No real reason. I was going back and forth between

Both zeros(Float32,nFullYears) and Vector(Float32,nFullYears) work. Thanks! I overwrite any contents, so unitialized is fine. There are rarely as many as forty of these (though there are four such vectors per issue), so it does add up, so I the performance analysis is much appreciated too.

Re: [julia-users] Circular parametric types

In the meantime, you can relax the second type definition to type t2{C, T} <: abstest x::C y::T end which will allow you to construct all the parametric types that you want, plus some more. You could add a check in the t2 constructor to make sure that T meets your expectations.

Re: [julia-users] Circular parametric types

Yes, you're right! I guess that you would have to break the chain at some point with Any or similar, which doesn't feel quite satisfying. But maybe it's the best that you can do for now. In your code, when you access fields that are not typed as strictly as you want, at least you can put in a

Re: [julia-users] Re: DateTime business days, Wall Street days, ...

My first impression on BusinessDays is that it's a brute force, first cut solution. For a small range of days it's probably just fine, but over several years performance is going to take a hit because every day in the range gets evaluated and every evaluation considers the entire set of
