I am writing a script to download warcraft 3 replays for me. It got a few (which work) then had an error: URI::InvalidURIError: bad URI(is not URI?): http://ftp.replays.net/ w3g/060607/060606_mYm]Lucifer(UD)_vs_mTw-LasH(Hum)_TwistedMeadows_RN.w3g The URL works in Safari, so I'm not su...
Hello, does anybody know _why_ 1.9.2 redefines libc symbols in r27214: int ruby_snprintf(char *str, size_t n, char const *fmt, ...); int ruby_vsnprintf(char *str, size_t n, char const *fmt, va_list ap); #undef snprintf #undef vsnprintf #define snprintf ruby_snprintf #define vsnprintf ...
Hello everyone! I'm happy to announce that Watir 3 has been finally released! Its biggest goal is to conform even better with WatirSpec making it more compliant with Watir-WebDriver. Changelog is quite long, but reading it makes your life easier: * Browser#status returns an empty stri...
Hi, I'm confused, I get this error by entering an IPv6 address in the set_real_ip_from directive: nginx: [emerg] "set_real_ip_from" supports IPv4 only in /usr/local/nginx/conf/nginx.conf:65 But according to the changelog, that directive should support IPv6 since nginx 0.8.22: Changes ...

> Does ruby support storing and loading bytecode !! Short answer: No, it doesn't. (Slightly) longer answer: No, *Ruby* doesn't support storing and loading bytecode, but most Ruby *Implementations* do. IOW: it's not part of the Ruby Language Specification, but most Ruby Implementations...
Rubies: My quest to get the maximum coverage & diagnostics from the leanest possible tests has reached a new level. This is a Rails functional test on an HTML form: user = users(:Moses) get :edit_user, :id => user.id assert_xhtml do form :action => '/users' do fieldset do legend 'Pers...
Bump Sorry for bumping such an old post. I'm having trouble trying to execute something similar. I am using the Apache::AuthenNTLM perl module for NTLM authentication (mod_auth_sspi is windows-only, correct?). Below are three configurations and my results. I appreciate any guidance an...
Douglas, I have been using cron tasks that invoke curl that invokes the routes that perform the periodic tasks for several years. This works on all versions of Rails (of course you have to be running *nix). I gave up on using Rails plugins, etc. because every time I did an update, the...

I have recently come across several related issues which I have tracked down to nginx and the way it handles DNS. I run nginx as a proxy for several back end services. It works really well, except for 1 thing. My proxy_pass refers to an upstream which points to a DNS entry. That DNS e...
Is there any good reason why Hash#map does not give back a Hash (Ruby 1.8 but same in 1.9 as far as I know)? I often find myself writing these kind of things: newhash = oldhash.inject({}) { |h,(k,v)| h[k] = some_operation(v); h } but that doesn't look pretty at all in my opinion. I wa...
