• Why does subshell not inherit exported variable (PS1)?

  - by amn

  After some debugging I finally narrowed down the problem as to why my X session xterm prompt does not appear according to my PS1 setting. If I run sh -c env, it doesn't even show PS1 in the list. Why? export PS1='test' sh -c env # No PS1 in the list, default prompt appearance (shell name + version) Substituting sh with bash yields same result, alas the behavior appears to be the same for both shells/modes. As far as I understood from man bash, the environment resulting from command run by shell with -c should include the exported variables. And it does - exporting FOOBAR results in FOOBAR listed in env run by subshell. It appears that the story is different if the variable is PS1 however. What is going on? I want my prompt propagated throughout the process tree and system. For matters sake, it is set in /etc/profile.d/user.sh (a file I created myself) with the following: PS1='\u@\H \w \$ ' export PS1 I am running Arch Linux (updated yesterday.)

• HTACCESS Rewrite problem

  - by TiuTalk

  I have this folder structure: /var/www/mysite/abc/ /var/www/mysite/def/ /var/www/mysite/fgh/ /var/www/mysite/ijk/ /var/www/mysite/portal/ /var/www/mysite/wyz/ Today's my server is redirecting all requests of www.mydomain.com to www.mydomain.com/portal and that's ok... But I want to modify this behavior and keep www.mydomain.com acessing the /var/www/mysite/portal/ folder on background while www.mydomain.com/abc/ still acessing the /var/www/mysite/abc/ folder as before. That's what i've tried without sucess on my htaccess: IndexIgnore * Options +FollowSymlinks <IfModule mod_rewrite.c> RewriteEngine On #This doesn't work!!! #RewriteCond %{REQUEST_URI} !^abc #Neither this :\ #RewriteCond %{REQUEST_URI} !^/abc RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^$ /portal/index.php [L] RewriteRule . /portal/index.php [L] </IfModule> All requests keep goin to www.mydomain.com/portal/ when I use this .htaccess (with or without the commented lines)

• Rails - Trying to query from a date range...everything from today

  - by ChrisWesAllen

  I'm trying to figure the best way to query a date range from rails...I looked around on Google but am unsure about how to use this syntax. I have a Model that has various events and I like to add to my find condition a caveat that should only show events where the field :st_date is today or later, in effect only show me data that is current, nothing that happened before today. I ran into a problem because I have no end date to stop the query, I want to query everything from today to next month. I was thinking something like @events = Event.find(:all, :conditions => ["start_date between ? and ?", date.Today, date.next_month.beginning_of_month]) but I get the error undefined local variable or method `date'...... Do I need do anything particular to use the Date class? Or is there something wrong with my query syntax? I would really appreciate any help.

• Transfer Win8 user settings between profiles [closed]

  - by GlennFerrieLive

  Possible Duplicate: How do I sync grouped Windows Store apps between devices? Is there a way for me to copy/save/transfer my "start menu" configuration, meaning the grouping and ordering of the elements on the Start screen, between user profiles? Is it in the registry?

• Disable/configure Back and Forward through mouse wheel in Internet Explorer

  - by Subtwo

  I have a problem with Internet Explorer (version 7 on Windows XP). Sometimes (not always) when you use the mouse wheel to scroll a page up/down it instead chooses to go back or forth in the web browsing history. This behavior is the same as when you hold the shift-key simultaneously using the wheel. My guess is that Internet Explorer somehow gets misled by something and thinks that I'm actually pressing shift. This is in turn maybe an artifact of the fact that this particular session is a remote-desktop session originating from Linux (Ubuntu). Needless to say the problem can be quite irritating and the alternative of completely turning off the wheel functionality doesn't seem like an option as other applications would suffer greatly from this. Anyway back to my question(s): Is it possible to map the shift+wheel to a simple wheel event for Internet Explorer? Is it possible to disable the shift+wheel event for Internet Explorer? Any suggestions are greatly appreciated.

• How can I get Visual Studio 2008 to align my assignment operators?

  - by Alison R.

  I had this in Vim and miss it dearly now that I'm confined to Visual Studio. I'd like to take this: MyType type_obj = new MyType(); MyLongerType longer_type_obj = new LongerType() To this: MyType type_obj = new MyType(); LongerType longer_type_obj = new LongerType() I have found some macros for this on the web, but they seem to be for an older version of Visual Studio (< 2008). Here is one from 2000. Edit: Further digging in Google turned up this one: http://www.omegacoder.com/?p=8 It seems to work to align equals signs, but I haven't yet figured out if it can align the local variable names, too. Still no clue as to whether I could just get it to perform this sort of behavior with a Ctrl E+D, although that might not be practical considering how it works. (It aligns going down from the line which currently has focus.)

• Use msysgit/"Git for Windows" to navigate Windows shortcuts?

  - by Darthfett

  I use msysgit on Windows to use git, but I often want to navigate through a Windows-style *.lnk shortcut. I typically manage my file structure through Windows' explorer, so using a different type of shortcut (such as creating hard or soft link in git) isn't feasible. How would I navigate through this type of shortcut? For example: PCUser@PCName ~ $ cd Desktop PCUser@PCName ~/Desktop $ ls Scripts.lnk PCUser@PCName ~/Desktop $ cd Scripts.lnk sh.exe": cd: Scripts.lnk: Not a directory Is it possible to change this behavior, so that instead of getting an error, it just goes to the location of the directory? Alternatively, is there a command to get the path in a *.lnk file?

• Setting subversion "password-stores" does nothing?

  - by Coderer

  The Subversion documentation says that I can set a parameter in ~/.subversion/config like [auths] password-stores = gnome-keyring to have it cache my certificate password in gnome-keyring. I set the option, and nothing happens -- no error messages, no change in behavior, nothing. Maybe I'm missing a log somewhere? I know subversion has to be compiled to support this but AFAIK I'm using the RPM version, which (they say...) ships with it rolled in. Is there a way to check whether my binary supports keyring? Shouldn't it say something if it doesn't?

• Property value of a String object in JavaScript

  - by naivists

  As far as I understand, every string is an object in Javascript. Still, it "does not work" as I expect it to be: var a="abc"; //here we get a new string object a.b = 123; //I seem to declare a property "b" of that object alert(a.b); //alerts "undefined" However, if I try to define a string in the "wrong way", everything works as expected var a=new String("abc"); // a.b = 123; alert(a.b); //alerts "123" Why is that so?

• Accessing an API

  - by Paritosh Praharaj

  I'm trying to build a Rails app where I have to access the Zomato API Could anybody guide me on how to create the Controller and View. Suppose I want to get the name of the restaurant from this URL: Restaurant, how do I write the controller and views for it. Currently, I'm using HTTParty gem. This is my controller code: def restaurants @response = HTTParty.get("https://api.zomato.com/v1/restaurant.json/773", :headers => {"X-Zomato-API-Key" => "MYAPIKEY"}) puts response.body, response.code, response.message, response.headers.inspect @categories = Category.where(:category_name => 'Restaurants') end And I'm trying to get the response object in the view: <%= @response.each do |item| %> <td><%= item.id %></td> <td><%= item.name %></td> <td><%= item.url %></td> <% end %> So, this shows the following error: undefined method 'id' for ["id", 773]:Array

• Elevate the weight of browsing history in Google Chrome's autocomplete

  - by maayank

  Google Chrome has the feature of auto-completing web addresses while you type them in the address bar. Alas, it gives absurdly more weight to Google's own auto-suggest v.s. my own browsing history, which seems a bit foolish - if I regularly (i.e. twice a week) check a certain website with the keywords "foo bar ponies" in its url, it is reasonable to expect that I will want to visit that site again and not other sites. While a bit subjective, to the very least I would expect such URLs to be in the list Chrome suggests, even if not at the top. Is there some plugin/secret option that alters the default behavior?

• passing self data into a recursive function

  - by user272689

  I'm trying to set a function to do something like this def __binaryTreeInsert(self, toInsert, currentNode=getRoot(), parentNode=None): where current node starts as root, and then we change it to a different node in the method and recursivly call it again. However, i cannot get the 'currentNode=getRoot()' to work. If i try calling the funcion getRoot() (as above) it says im not giving it all the required variables, but if i try to call self.getRoot() it complains that self is an undefined variable. Is there a way i can do this without having to specify the root while calling this method?

  I have a JQuery function as followss: (function($){ $.fn.autoSuggest = function(data, options) { function add_selected_item(data, num){ (function($){ $.fn.autoSuggest = function(data, options) { alert(data); } }); } }); If I wanted to call the local add_selected_item() function from outside this function, how would I do it? I've tried doing: $.autoSuggest.add_selected_item(data, opt); But am getting an $.autoSuggest is undefined. Still learning the ropes with JQUery. I am not sure exactly how this can be accomplished, if at all. Thanks!

• How do I get started writing a .Net-wrapper around C++ Omniorb-stubs

  - by Superfisi

  Hello there, my job is to access a CPRBA-server-application from .NET 3.5. After evaluating projets like IIOP.Net (undefined state) and products like VisiBroker (expensive) I'd like to do it "by myself" and write a .Net-Wrapper around C++-Stubs generated my Omniidl (the Omniorb IDL to C++ generator). This means writing some kind of layer of managed code (CLI) around the unmanaged C++ code. My question is: Has anyone experience in this topic? I honestly don't know how to do it the best way. Right now I plan to create a managed class for every unmanaged class, each managed class itself has a member to an instance of the unmanaged class, which is not garbage-collected. Is this the right way to do it or am I on the wrong path? Thanks in advance!

• Starting out with vote_fu

  - by zizee

  Hi All, Trying my luck with the vote_fu rails plugin. The functionality looks like exactly what I need for a project of mine, but I have hit a roadblock. I have followed the github readme to the letter, installing it as a plugin. I have put acts_as_voteable on my "Event" model and acts_as_voter on my User model. In the console, when I try: >> event.votes or >> user.votes it successfully returns an empty array. but when I try to do the following: user.vote_for(event) I get "NoMethodError: undefined method `user_id' for #<Vote:0x7f5ed4355540>" Any ideas? I'm probably just missing something obvious, but maybe something is missing from the plugin's readme. Thanks.

• jQuery UI sortable issue

  - by colourandcode

  When I try to use a sortable event . (For instance the stop() event) It only works when I bind it using : $('.selector').bind('sortstop', function(event, ui) { ... }); rather than $('.selector').sortable({ stop: function(event, ui) { ... } }); Is there a missing piece in this? The only reason I ask is because when I bind using the actual bind() method it's not giving me access to the event or ui parameters I pass in. I'm always returned undefined.

• Slowness on Exchange 2007 Server (network related we think)

  - by Az

  We are seeing some odd behavior out of our exchange 2007 server. I believe it is network related as during the slowness in response from the exchange server. During these times downloading files to server is fraught with connection resets and extreme slow download speeds that are not affecting other servers right on the same subnet with the same gateway and ISP. We have about 50 users at a time using Outlook 2003 from a terminal server not displaying any other signs of slowness, all network slowness is confirmed trying downloads on the exchange server itself. Checked for virus issues, there are none. Checked for hardware issues, none found I am noticing between 200-400 TCPv4 connections established I am seeing around 100k tcpv4(active) connections according to perfmon are these numbers odd? Has anyone run into anything similar? Our server has a gigbabit NIC linked to a gigabit switch using cat6 so I do not believe it is "physical". Thanks!

• Preventing Windows from automatically removing broken desktop shortcuts

  - by hkBattousai

  I have two external harddrives which I'm using for archiving purposes, because of that they are turned off most of the time. I have some shortcuts on the desktop to some directories on these external harddisks. Windows occasionally removes these desktop shortcuts. It happens when the harddisks are turned off. I think it thinks that the shortcuts are broken and no longer needed, and tries to clean the desktop up. How do I prevent this behavior? (OS Version: Windows 7 Ultimate x64 SP1)

• Force '^C' to be printed when editing current prompt, then aborting it

  - by Stefan Lasiewski

  This is the opposite of Prevent “^C” from being printed when aborting editing current prompt. I'm using Bash. When I'm editing the commandline in Bash, and I hit Control-C to abort the commandline, the '^C' character does not display. I would like to see this character. I tried commands like stty -ctlecho and stty ctlecho (which I borrowed from the other question), but this didn't work for me. This behavior seems to be true with my environment on Ubuntu, CentOS and MacOSX.

• Modifying a global variable from <a href>

  - by a_m0d

  I have created some code to popup a confirm dialog if a user tries to leave a page without saving their changes. However, I don't want the confirmation dialog to popup if the user has clicked the "Save" button. I have some code at the top of my file which looks like this: var confirmClose = false; window.onbeforeunload = function(evt) { if (confirmClose == true) { message = "There are unsaved changes on this page. Are you sure you wish to leave?"; if (typeof evt == 'undefined') { evt = window.event; } if (evt) { evt.returnValue = message; } return message; } } Further down on the page I have a link which looks like this: <a href="javascript:confirmClose=false;$('#stockForm').submit()" title="Save" class="button positive" id="stockFormSubmit">Save</a> However, this doesn't seem to work - it doesn't seem to change the value of confirmClose, and changing it to window.confirmClose didn't help either. What am I doing wrong here?
