  • Using functions and environments

    - by Eduardo Leoni
    Following the recent discussions here (e.g. 1, 2 ) I am now using environments in some of my code. My question is, how do I create functions that modify environments according to its arguments? For example: y <- new.env() with(y, x <- 1) f <- function(env,z) { with(env, x+z) } f(y,z=1) throws Error in eval(expr, envir, enclos) : object 'z' not found I am using environments to keep concurrently two sets of simulations apart (without refactoring my code, which I wrote for a single set of experiments).

  • The entire User Interface freezes/becomes unresponsive for up to 20 seconds

    - by user2400801
    I am a rails developer, using Ubuntu 13.10 installed on a Asus S550C Ultrabook (was a windows 8 machine originally) Every day I work with Sublime Text 2, Google Chrome, and Terminal (about 6 tabs open) The problem: clicking on the menu bar (eg File - Save) while using Sublime Text 2 will occasionally (eg almost always) make the ENTIRE COMPUTER freeze for up to 20 seconds. This occasionally happens when I go to log out / lock my computer. Sometimes it doesn't freeze completely but rather is just very sluggish and then recovers. I don't know if this is a problem with Sublime Text 2, or the Ubuntu 13.10 operating system. (Thanks for reading) Best Regards

  • Rails modeling for a user

    - by Trevor Hartman
    When building a rails app that allows a User to login and create data, is it best to setup a belongs_to :user association on every single model? For example, let's say a user can create Favorites, Colors and Tags. And let's say Favorites has_many :tags and Colors also has_many :tags. Is it still important for Tags to belong_to :user assuming the User is the only person who has authority to edit those tags? And a similar question along the same lines: When updating data in FavoritesController, I've come to the conclusion that you perform CRUD operations by always doing something like User.favorites.find(params[:id].update_attributes(param[:favorite]) so that they can definitely only update models that belong to them. Right?

  • Windows 7 hangs after longer inactivity of user

    - by scooby37
    I have serveral PCs running Windows 7 in different falvors (32- / 64-bit / Professional / Ultimate / ATI / Nvidia) - they all have one problem in common... ...if I don't work on any of them for a longer time and the screen goes off as it should be (all default settings!) they sometimes go into some kind of sleep mode where I get to see the desktop or whatever I did before leaving after moving the mouse or pressing a key - but nothing reacts for a different amount of time from serveral seconds to serveral minutes! Any hint that helps solving this anoying problem would be very welcome ;-)

  • Ubutu Server Edition: useful for the home user?

    - by D Connors
    My question is simple. What (if anything) does Ubuntu Server Edition have to offer to home users? This question is mostly out of curiosity really, but I like asking. I've got a home network set up here with some 6 to 7 machines (most Windows, one Linux). And I was wondering how useful would it be to have a dedicated computer in my house running Ubuntu Server full time. We've had an awful experience with file sharing so far, would it simplify file sharing/transferring? Would I be able to limit the internet bandwidth granted to each PC? Would I be able to monitor in/out internet traffic (both real time and monthly statistics)? Last, and most important, if I'm completely off as to what Ubuntu Server actually is, please say so. I am completely new to it.

  • JavaScript Self Executing Functions - What's the Difference?

    - by modernzombie
    I am very familiar with self executing functions from working with jQuery. (function($) { /* do stuff */ })(jQuery); Today I was reading the backbone.js source and noticed that they do this: (function() { /* do stuff */ }).call(this); Is this achieving the same thing? Would the following 2 lines of code do the same thing? (function($) { /* do stuff */ })(jQuery); (function($) { /* do stuff */ }).call(jQuery);

  • Cannot change User Accounts settings

    - by eimmy
    I recently changed the name of the administrator and turned off passwords then clicked lock. After some time, I decided to add a password so I clicked on unlock and it's prompting me to enter a password. I tried typing the old password and it didn't accepted it. I also tried to set password and keys as "set to default" but still nothing happened. Now I'm stuck and can't get to change the administrator settings. I did my research but nothing seems to work. Please help.

  • Get node parent of defined type using xpath

    - by IordanTanev
    Hi, i will give an example of the problem i have. My XML is like this <roor> <child Name = "child1"> <node> <element1>Value1</element1> <element2>Value2</element2> </node> </child> <child Name = "child2"> <element1>Value1</element1> <element2>Value2</element2> <element3>Value3</element3> </child> </root> I have xpath expression that returns all "element2" nodes. Then i want to for every node of type "element2" to find the node of type "child" that contains it. The problem is that between these two nodes there can be from 1 to n different nodes so i can't just use "..". Is there something like "//" that will look up instead of down Best Regards, Iordan

  • Windows 7 user limitation

    - by Eildosa
    I just installed Windows 7 pro x64 from Dreamspark (MSDNAA). But i can't figure out how to configure it. 1/ When I want to acces some folders a pop up show up and tells me "that I need administrator acces to do it" I click the "continue" button and I can go inside the folder. What was even the point in showing me this pop up? how can I remove it? 2/ In some folder when I do a right clic I can only create a new folder, not a new text file, not a rar, nothing. In the same folder I also cannot extract RAR (by doing right clic, extract here) Any Idea how to get back full control? Thanks.

  • return only one document for each filter defined in the query

    - by Garytxo
    Hi all, In one of my latest projects I use Solr 1.4 for searching products.However I have ran into a slight problem, which I aint sure if its possible to do using Solr. All products are indexed by "country" and "category" and the "id", "class" and "description" are stored values. I now have been requested to extract a sample list of products that we have for a give "category" and "ONLY RETURNING ONE" product for each country where the product is available. In my current implementation, I have a dismax query to get a list of all the countries that correspond to the catergory, then I call again solr to extract all products for each country, limiting the no. rows by the size of the countries found in the previous query. The problem I have with this current implementation is I can not be certain that I have one product for each country in the list. Therefore would anyone know if it possible to tell solr that you want only one product per country provided in the query? Any guidance would be useful.

  • Creating multiple objects of a view defined in the xml

    - by user362953
    I have to dynamically add a list of views (the views use RelativeLayout). Can I do this by specifying the view definition in xml and instantiate multiple objects off it? This gives the usual benefits of separating the view part from the code (for e.g., making it easy for the UI guys to alter things) or Is going the ArrayAdapter the suggested/only route?
