Exceptions/Errors in many other programming languages (say java, ruby) always provide stacktrace/backtrace information. In JavaScript unhandled Errors get caught by window.onError. Although that function does not get the Error object, so we have no access to the object's stack property. Is there any reliable source of information about when will there be any change on that?
The amount of workers you should use depends greatly on what your app itself is doing and how ofter it is doing those things. There really isn't a perfect ratio formula for it unfortunatly that will work in every single test case. This becomes even more true when you take into account the fact that you have a finite amount of RAM that you have to keep your server on. Many will suggest that CPU Cor
I'm just learning to use SQLite and I was curious if such is possible: Encryption of the database file? Password protect opening of the database? PS. I know that there is this "SQLite Encryption Extension (SEE).", but according to the documentation, "The SEE is licensed software...." and "The cost of a perpetual source code license for SEE is US $2000."
I have the below background job that writes to a csv file and emails it out. I am using the Tempfile class so the file is removed after I email it to the user. Currently, when I look at the csv file I am producing the results look like the following: ["Client Application" "Final Price" "Tax" "Credit" "Base Price" "Billed At" "Order Guid" "Method of Payment Guid" "Method of Payment Type"] ["web" ni
I use htop to view information about the processes currently running in my osx machine, also to sort them by CPU, memory usage, etc. Is there any way to fetch the output of htop programatically in Ruby?. Also I would like to be able to use the API to sort the processes using various parameters like CPU, memory usage, etc. I can do IO.popen('ps -a') and parse the output, but want to know if there i
Is there a JavaScript equivalent of Java's class.getName()? No. ES2015 Update: the name of class Foo {} is Foo.name. The name of thing's class, regardless of thing's type, is thing.constructor.name. Builtin constructors in an ES2015 environment have the correct name property; for instance (2).constructor.name is "Number". But here are various hacks that all fall down in one way or another: Here is

I have created a new rails3 project but I am seeing following logs many times in my server logs. Why I am getting these request and how can I avoid these?

I was working on a new Rails 4 app (on Ruby 2.0.0-p0) when I ran into some authenticity token problems. While writing a controller that responds to json (using the respond_to class method), I got to the create action I started getting ActionController::InvalidAuthenticityToken exceptions when I tried to create a record using curl. I made sure I set -H "Content-Type: application/json" and I set the
I'd like to understand what's really going on when signing in a user with rails/devise. I've created a minimal rails app, installed devise and created a User devise model. Everything works fine, and when I log in (using remember me) I get a session cookie just as expected. Now what's bugging me is : How does rails handle the session informations that the browser is passing through the cookie ? I'd
I need to query comments made in one day. The field is part of the standard timestamps, is created_at. The selected date is coming from a date_select. How can I use ActiveRecord to do that? I need something like: "SELECT * FROM comments WHERE created_at BETWEEN '2010-02-03 00:00:00' AND '2010-02-03 23:59:59'"
