What is the hex number after the method, e.g. +0x32f below? It matches arg0 and I suspect it''s the c++ "this" pointer, aka hidden first argument. I would like to confirm, though. Thanks, Joel --- XUL`PresShell::ProcessReflowCommands(int)+0x32f XUL`PresShell::FlushPendingNotifications(mozFlushType) +0x19e

Folks, I'm new to R and would like to use it to analyze web server performance data. I collect the data in this CSV format: 1304083104.41,Y,668.856249809 1304083104.41,Y,348.143193007 First column is a <seconds.microseconds> timestamp, rows with N instead of Y need to be skipped and the last column has the same format as the first column, except it's request duration (latency).

Does R have support for microseconds in timestamps, e.g. when reading this in "Time","Include","Kind","Duration" 2011-04-01 14:20:36.368324,Y,U,1.03238296509 2011-04-01 14:20:35.342732,Y,C,0.0252721309662 2011-04-01 14:20:34.337209,Y,R,0.00522899627686 Thanks, Joel -------------------------------------------------------------------------- - for hire: mac

I added a couple of static probes to Firefox to measure actual work done. I could have used a pid$target probe with a function name but work is done within an if statement, which is where I placed the static probes. I''m wondering about my use, though. Is the following significantly more efficient than pid$target::FunName:entry and return? I heard somewhere that $target does not

Suppose I have a USDT probe in Firefox and that I''m trying to catch the startup with a probe like this: proc:::exec-success /execname == "firefox-bin"/ { start = timestamp; } and stop tracing when Firefox hits this USDT probe: mozilla:::main-entry { exit(0); } How do I put the running firefox-bin into "trace mode" so that my USDT probe fires? Thanks, Joel

Folks, My understanding of how filters work is that I should return true if everything is ok and false if not. How does the filter below work then (from the Rails Recipies book)? It would return nil if there''s a user in the session. Does nil count as true? before_filter :check_authentication def check_authentication unless session[:user] session[:intended_action] =

Folks, I checked my test_helper.rb and it has self.use_transactional_fixtures = true My code was generated with 1.1.2 and I''m using 1.1.3 right now after but the error persists. I googled for this issue and it appears that a require is missing or something like that. I can''t figure it out, please help! /opt/local/bin/ruby -Ilib:test

Is there a more elegant way of writing this? def verify_user @user = User.find_by_username params[:username] if @user.nil? message = xml.error do |xm| xm.message "User does not exists: #{params[:username]}" end render :xml => message return false else true end end Thanks, Joel --

Has anyone tried manually creating session objects and storing them in the database? I''m taking about a setup where the ActiveRecord session store is used. I''m sharing the database with a non-Rails platform and extended my session table to include other data that I need to store when the user logs in. Thanks, Joel -- http://wagerlabs.com/

I have a script where I can freely reference struct nameidata*, struct vnode*, etc. on Snow Leopard. How does DTrace know about these data types? I understand things like #pragma D depends_on library darwin.d where darwin.d has typedefs. I can''t find definitions of nameidata and vnode in any D scripts, though. How does it work? Thanks, Joel --- firefox for android!

Folks, I have the standard setup with auto-generated unit tests and fixtures. I edited the fixtures and the tests but would now like to test associations from irb. How do I do this? I''m not sure how to load my fixtures into irb, for example. Once they are loaded I would create objects, save them to the db and pull things out. Thanks, Joel -- http://wagerlabs.com/

I''m trying to time a function within Firefoxwith a pid$target probe [2]. e.g dtrace -Zqw -x dynvarsize=64m -x evaltime=preinit -p 13954 -s menu- construct.d -s sigcont.d elapsed: 12.7942481ms cpu : 7.7911194ms count : 40 times I''m also measuring Firefox startup time by running it arguments like this: ... file:///Users/joelr/work/mozilla/startup/startup.html#`python

Does dtrace have a problem catching the return from memset on Mac OSX? The script below catches the entry just fine but the return clause is never entered. Thanks, Joel --- pid$target::memset:entry /arg1 == 0/ { self->size = arg2; self->ts = timestamp; self->vts = vtimestamp; } pid$target::memset:return /self->size/ { @ts = sum(timestamp - self->ts); @vts =

Folks, I''m using the session db table to store additional data. When a user logins I would like to store their user id in the session record and save that. I''m thinking of x = Session.find(session.id) and then x.save. Is this the right way to do it? Thanks, Joel -- http://wagerlabs.com/

Folks, I''m trying to write a validating filter that checks if the user exists and renders XML if not. Most of the controllers will be returning XML on some error or other so I''m including RenderError in ApplicationController. Is my approach a sound one? Also, is there a shorter and more idiomatic way of writing this: if @user.nil? render_user_exists

I have two functional tests for my user controller: def test_bad_registration post :register, :email => "tester1@foo.com" assert_response :success assert_not_nil @response.body =~ /^\<error/ assert_nil assigns[''user''] end def test_good_registration @response.body = nil post :register, :username => "tester",

Hi! The Netfilter project proudly presents: nftables 0.7 This release contains many accumulated bug fixes and new features available up to the (upcoming) Linux 4.10-rc1 kernel release. * Facilitate migration from iptables to nftables: At compilation time, you have to pass this option. # ./configure --with-xtables And libxtables needs to be installed in your system. This allows

I''m just wondering what happened to Armageddon and whether people had any more information/news about it. I''ve thought about comet but I think that a flash socket would be easier to implement. Does Armageddon have the same drawbacks as other flash sockets, namely not working over port 80 (so the companies firewall blocks it)? -- Posted via http://www.ruby-forum.com/.

Some future Dovecot version will have "imap-idle" processes where IDLEing IMAP connections get moved, so the system wouldn't waste so much memory for all the IDLEing imap processes. A week ago I thought I'd see how easy it would be to implement this. I got a basic proof of concept working as a "X-STATE" command. Save the state: a x-state * STATE
