I was just looking for a way to tell the OPA http server what port to listen
I found this article http://blog.opalang.org/2011/06/first-steps-hello-web-in-opa.html
that talks about the --port parameter
I'd like to know where are all these parameters documented
Just run opa --help or man opa ;)
myapp.exe --help will print possible options for your compiled Opa app.
I agree, it would great to add a chapter about common options in the online documentation.

For some time I was using code:
hostname = Socket.gethostbyname(Socket.gethostname).first
taken from here.
But, as the comment said - it's deprecated, and now both rubocop and ruby itself are complaining:
=$ ./z.rb
./z.rb:5: warning: Socket.gethostbyname is deprecated; use Addrinfo.getaddrinfo instead.
=$ rubocop z.rb
...
z.rb:5:13: W: Lint/DeprecatedClassMethods: Socket.gethostbyname is deprecated in favor of Addrinfo#getaddrinfo.
puts Socket.gethostbyname(Socket.gethostname).first
^^^^^^^^^^^^^
The problem is that I don't know how to use getaddrinfo to get the same information. Anyone could show an example?
For now, I figured I'll just use:
`hostname --fqdn`
which works, as I only run it on Linux, but it's not really nice approach.
Got help in some other way, but figured others might benefit too.
Current way to do it is:
require 'socket'
Addrinfo.getaddrinfo(Socket.gethostname, nil).first.getnameinfo.first
Is there a way to change protractor's default debugger port 5858? Currently I'm using the following command to launch protractor:
$> protractor debug protractor.conf.js
There's an optional parameter you can pass to pause to use a different port, e.g. browser.pause(5859) :
https://angular.github.io/protractor/#/api?view=Protractor.prototype.pause
The port is hardcoded in several locations of the protractor code:
https://github.com/angular/protractor/search?q=5858&ref=cmdform
So i guess, you could fill an issue explaining your requirement, or you could fork, modify protractor and make a pull request.
I have been using Thin to run my ruby Sinatra applications but I am now switching over to Puma. Thin creates its own log log/thin.log which I use. I noticed that Puma doesn't produce a log file (not that I can see). I have tried googling for documentation around this but not really found anything.
I was wondering if/how you can specify a log path in Puma.
Any help would be much appreciated.

Check the example config.rb as recommended on the repo's README.
As shown there:
# Redirect STDOUT and STDERR to files specified. The 3rd parameter
# (“append”) specifies whether the output is appended, the default is “false”.
stdout_redirect '/u/apps/lolcat/log/stdout', '/u/apps/lolcat/log/stderr'
stdout_redirect '/u/apps/lolcat/log/stdout', '/u/apps/lolcat/log/stderr', true
I would like to make HTTP requests from Rails code running on top of JRuby.
How can I make it to re-use http.proxyHost, http.proxyPort and http.nonProxyHosts settings, given to JVM running it ?
To pass JVM flags through JRuby, use -J.... In this case:
jruby -J-Dhttp.proxyHost=foo -J-Dhttp.proxyPort=1234 -J-Dhttp.nonProxyHosts="*.bar.com" ...
This is explained in JRuby's help text.
-J[java option] pass an option on to the JVM (e.g. -J-Xmx512m)
use --properties to list JRuby properties
run 'java -help' for a list of other Java options
I have had the same issue. I found that java or net::http doesn't obey the nonProxyHosts option. The best way to get around this is to modify the ENV_JAVA settings to account for this.
The steps I took to ensure nonProxyHosts was used were the following:
1) JAVA_OPTS="-Dhttp.proxyHost=192*** -Dhttp.proxyPort=1234 -Dhttp.nonProxyHosts=local|127.0.0.1"
OR
1) JRUBY_OPTS="-J-Dhttp.proxyHost=192*** -J-Dhttp.proxyPort=1234 -J-Dhttp.nonProxyHosts=local|127.0.0.1"
Keep in mind that at least for java1.7 the nonProxyHosts should not have quotations see here.
Now I find that either net::http or java itself doesn't actually honour the nonProxyHosts option.
However you can get around this by doing the following in JRuby
a = URI("http://someurl")
Net::HTTP.new(a).proxy?.should == true
regex = /$#{ENV_JAVA["http.nonProxyHosts"]}/ #dollar needed to behave as expected
if a.hostname.match(regex)
ENV_JAVA["http.proxyHost"]=nil
end
Net::HTTP.new(a).proxy?.should == false
Hope that helps.
Is there a way to control the Fujitsu Softune debugger with an other application(e.g. Eclipse)? I think about sending the command mentioned in the documentation of Softune and parse the output, but also other approaches are welcome.
There is pluging for eclipse; file name is "FujitsuF2MC16_1.0.1.jar", look for it on this page:
http://www.mikrocontroller.net/topic/70413
Complile en debug in eclipse.
Hope this helps.
What do you mean by controlling the Fujitsu Softune debugger?
If what you want to do is to start a debugging session with your freshly-compiled .abs file, you can do the following.
In the Eclipse environment add a button or shortcut to call the make utility to make a debug:. Your makefile would have an entry like:
debug: $(make_vars)
# start debugger
make -f$(make_vars) -f$(make_dir)/$(cfg) cfg="$(cfg)" debug_session
In the make entry for debug_session you put something like:
echo UPDATING SOFTUNE-3 PROJECT FOR DEBUGGING;\
$(subst \,/,$(DIR_SOFTUNE_WORKBENCH))/bin/Fs907s.exe softune/E7x_proj.wsp 2>/dev/null;
I hope this was useful.
