I'm trying out Dates (using Dates, in 0.3.3-pre+8). I would like to

Is there a way of constructing a DateTime from the previously serialised
Uint64?

Okay, it turns out it's not very hard at all to use the opensuse build
service, fork the package that's causing trouble, and revert it back to the
last working state.
See https://build.opensuse.org/package/show/home:kelman/mingw64-tk
You can use this by doing the following:

Sorry about this Miguel. We use a build service from OpenSUSE to download

Currently the way to do is to explicitly call the R-level setter:
x = Rif.R("names<-")(x, Rif.cR("A", "B", "C"))
However, as of today commit the C-level is exposed and a way that is
looking a little more like native Julia.
(I'll do a pull request so this is part of the released package soon).

I found by chance this post. I wanted to let you know that I'm also based

it would be great to know if there are other users in the area
Thanks for your response. That worked.
Hi,
I recently updated to julia 0.3.2, and now I have problems with some
packages. I removed the .julia directory, and reinstalled, but the problems
appeared again (some packages had build errors).
I don't remember exactly which packages it was, but the first error I
noticed was:

If you do `git checkout release-0.3` then you will be on the `release-0.3`
branch instead of `master`; you can then proceed exactly as you used to but
will only get the relatively conservative changes on that stable release
branch.

Hi, I am currently using julia v0.3.1-pre+4 under a debian gnu/linux system
and would like to upgrade to the latest stable version 0.3.2. Should I
recompile from source or is there a faster way?
I used to do `git pull origin` but I guess that would retrieve the 0.4
version of julia.
Thanks for

So no mixup, just a different perspective than you’re taking right now.
My best advice: discard everything you know about R while using Julia. If
you’ve used Matlab, that will be much more useful as an analogy for how Julia
works.
Haha. That's entirely possible :-)

I am a bit confused. Take a look:
size(m, 1) # returns size of rows
size(m, 2) # returns size of columns
sum(m, 1) # sums columns
sum(m, 2) # sums rows
Also, I have R background, and there 1 is used for rows, 2 - for columns.
Why Julia mixes this up?

I’ve often wished we had a Julia reading list that provided useful references
for people wanting to learn about the big ideas involved in Julia.

Are you sure you setup the path to the julia executable right? I'm on OS X
and have julia in my path so the default settings are fine for me but on
windows you either need to add the julia to your path or set it up in the

Yes, it helps a little bit.
The question was rather on what to read (what book to read) to be able to
follow discussions like Stefan's and John's discussion here. Obviously the
julia type system is a benefit for the compiler.
