Re: [julia-users] segfault when building master on linux
Sorry bout that, I have a knack for causing build issues that end up making everyone rebuild llvm as accidental (or sometimes necessary) side effects of fixing other various things. make -C deps distclean-llvm should be enough for this and hopefully it won't come back after that. fe193b532d8b18b7dd5a68c363dd0850b78dbf50 was my fix for an actual build issue (only seen on ARM and Power) with trying to apply patches multiple times, but it was flawed and actually broken for from-scratch builds (which I should have tested! the CI and buildbots, most of the time, test incremental rebuilds with the deps still in place or cached from the previous build). c31c5f69955644f0c5d9ff6f41c33c5751f6ef77 fixed the flaw in the earlier commit to make from-scratch builds work again, but for reasons I don't entirely know, caused this segfault issue (likely due to one or two of our llvm patches not getting applied, or getting reversed, or something. our makefiles are nasty convoluted beasts that we need to eventually replace with something more uniform, standardized, and less error-prone).

well, checking out and building completely from zero fixed it, whatever it was.

There is more that one may do using UTime, take a look at the README
examples.
It has been some time since I revisited it, so please ask if you have any
questions,
and let me know if there is something that is not now working as it had.
I just ran the examples above in v0.5-.

Jeffrey

[julia-users] Re: unable to connect to FTP using IP address
Hi Samuel,
Here is how it is done in matlab
% connect to ftp
f = ftp(host, username, password)
mget(f,'dataOnFTP.bin')
% read data from file
readData = fopen('dataOnFTP.bin', 'r', 'ieee-le')
%delete file from server
delete(f, 'dataOnFTP.bin');
Here one thing not included is I would like to find the latest file from
FTP server because there might be similar names with different suffix.
Thanks
Yared

Re: [julia-users] Does a wrapper for gmtime exist
IIUC, the Julia DateTime object represents UT (milli)seconds, and has converters to/from human-readable dates and local time. http://docs.julialang.org/en/release-0.4/manual/dates/ On Wed, Jul 27, 2016 at 9:32 AM, Andrew Gibb wrote: > Hi, > > I'm writing a module for dealing with video timing.

[julia-users] Does a wrapper for gmtime exist
Hi, I'm writing a module for dealing with video timing. The C++ code I'm using as a basis uses gmtime to convert seconds into y:m:d.etc. Does anyone know if this functionality is exposed in Julia anywhere? I realise I could handle this myself with ccall, I just wanted to check to see if I could avoid duplicating effort. Thanks Andy
[julia-users] Embedding Julia - Multiple worker processes
Hi there, Is it possible to enable multiple worker processes when embedding Julia? I am just trying to get my head around Julia's Parallel Computing and from the docs it is possible to do this via a command argument when starting julia ( -p n ) http://docs.julialang.org/en/release-0.4/manual/parallel-computing/ However, is this possible when creating a Julia instance from C? jl_init() does not take any relevant arguments and I have not managed to find anything in the docs that suggests a way to do so once Julia is initialized? What I am really after is running some Julia logic on a dedicated worker thread in parallel with our main Julia code. Many thanks, Chris
