[julia-users] [ANN] ConnectionPools.jl

Hi all, Introducing ConnectionPools.jl , a package for managing database connection pools. Currently only Redis connections have been tested. I'll add tests for other databases on an as-needed basis. As always, thoughts/criticisms/suggestions

Re: [julia-users] Re: [ANN] LoggedDicts.jl

The existing support for Dict is flexible enough, but point taken - it could be nice. As an example, suppose the Associative of interest is a PriorityQueue. Then we can: using LoggedDicts using Base.Collections ld = LoggedDict("myld", "mydict.log") set!(ld, "pq", PriorityQueue()) set!(ld,

[julia-users] Re: [ANN] LoggedDicts.jl

Do you have any specific use cases in mind? I'd rather keep it simple and add features only when there's a compelling use case. On Thursday, April 7, 2016 at 8:46:33 AM UTC+10, Cedric St-Jean wrote: > > Neat! Could you support Logged{Dict}? Then it would work with any > associative

[julia-users] [ANN] LoggedDicts.jl

Hi there, Introducing LoggedDicts.jl . A LoggedDict is simply a Dict for which every write is logged to a user-defined output. Handy as a light-weight, intra-process data store in applications/scripts that do not require high write frequency

[julia-users] Defining part of a function outside its module

Hi all, This works: f(x) = g(x) * g(x) g(x) = x + 1 f(2)# 9 That is, f(x) isn't fully defined until g is defined. But if f(x) is in a module it doesn't work: module myfunc export f f(x) = g(x) * g(x) end using myfunc g(x) = x + 1 f(2) # ERROR: UndefVarError: g not defined That is,

Hi Leonardo, I'm not an Escher user, but I use SecureSessions.jl when building web apps with plain HttpServer.jl. If this is a little over the top then the source code should be helpful for implementing a simpler scheme. Hope this helps, Jock

OK, thanks Miles. I'll head to Optim.jl. Is there an intention to implement this functionality? Suggestion for julia-opt is noted, thanks again. On Tuesday, March 1, 2016 at 12:24:05 PM UTC+11, Miles Lubin wrote: > > There's no syntax for this at the moment, it's a known issue. The problem > is

[julia-users] How to have many arguments in a Jump.jl nonlinear model?

Hi there, I have a nonlinear varargs function f(x...) that I'd like to maximize. That is, the function is defined as follows: function f(x...) # do stuff here result end With a small number of arguments, for example 2, I can write the following and get the correct result:

[julia-users] How to use a variable for filename in @Logging.configure?

Hi all, I am using Logging.jl as follows: @Logging.configure(filename = "path/to/repo/mylogfile.log", level = INFO) This works fine. However I would like to set the log file name as a global variable (const my_log_file = "path/to/repo/mylogfile.log") and then call a script that includes the

Great, thanks Lex. The documentation for round is "round x to the nearest integer", which seems to be a mathematical definition that isn't quite equivalent to the IEEE spec. The docs ought to mention rounding to the

[julia-users] Inconsistent behaviour of round()

Hi there, I'm using Julia 0.4.0. round(4.5) gives 4.0, i.e. it rounds down. round(5.5) gives 6.0, i.e. it rounds up. Any ideas why this is the case? Cheers, Jock

[julia-users] Proposed change to HttpServer.handle signature

Yep, clone it. Also, note the updated README - it gives a crash course in web app development (as I understand it, which may be flawed) aimed at data scientists who have never built a web app before. Hope it helps. On Friday, November 1, 2013 at 3:00:25 AM UTC+11, Jonathan Malmaud wrote:

Hi Jonathan, Uncanny timing. Here https://bitbucket.org/jocklawrie/skeleton-webapp.jl is an example of Julia working with the Mustache.jl package which I posted just a couple of hours before your post. It works fine but is not nearly as mature as webpy. Hope you find it helpful. Cheers, Jock
