  • adding visual effects to RJS before action rendered

    - by Sam
    I just started using RJS which is awesome however I am used to putting visual effects in the link_to_remote and such and I'm not sure how to trigger actions before and after remotes are triggered. Take this link for example: HTML <span id="<%= "edit_comment_link_#{comment.id.to_s}"%>" style="float:left;"> <%= link_to_remote "edit", {:update => "comment_#{comment.id.to_s}", :url => edit_post_comment_path(comment.post, comment), :method => :get}%> | </span> Controller: def edit @comment = Comment.find(params[:id]) respond_to do |format| #format.html render edit_comment_path(@comment) format.js end end RJS: page.replace_html "edit_comment_link_#{@comment.id.to_s}", "currently editing | " So is RJS mainly for after actions are rendered visual effects such as a spinner should be put into the link_to_remote with call_backs? Is this a good way of doing things?

  • Oracle XE as local recovery database and Oracle Standard as main db

    - by jbendahan
    Hi, I just wanted to know what you guys think about this. I have an app written in Visual Basic .Net as my front end and and Oracle 11g Standart database as the back-end. So I have like 20 pc's running this app locally. They're all inserting, updating, deleting data on this single database. I want to develop a solution in the case that the server database crashes or cannot stay on line. So i think of having oracle 10g XE on each pc. Thus all the data will be stored in the local db. I think about running a proccess once in a while (ex. every 15 minutes) to send/get the data to/from the main server. What do you think about this strategy?

  • Full Backup & Restore for Windows Vista

    - by Thomas Matthews
    I'm looking for a freeware or low cost application that will backup everything, including registry on Windows Vista Home Premium and to restore from a CDROM disk. The destination is an external hard drive on USB 2.0. Searching on SuperUser and Stack Overflow show articles, but don't mention full backup of the registry and complete restore using CDROM. I would also like to have compressed output and incremental backups. One article mentions CloneZilla, but their web page says that the incremental feature is not supported. I am using Windows Vista Home Premium, Service Pack 1. I need to backup 200 GB onto a 230 GB drive and would like to have multiple backups (thus the need for compression). Other requirements: Single file restore Quality is more important than performance. Application must run on Windows Vista. Extra: Run as daemon or background task on 4 user system. Thanks

  • LinkedIn / Twitter / Facebook as OAuth and OpenId use

    - by monkeylee
    Firstly I understand OpenId is for authentication and OAuth is for authorisation and unlike other questions on the site I am not asking which should be used for which but if anyone can advise a solution for my issue. I want to allow users to login to my site via their LinkedIn/Twitter/Facebook account once logged in say via LinkedIn they could also then authorise their Twitter and Facebook account as a optional login method. This would allow the user to authenticate via any of the three but end up with their user account on my site as the end result. I also want to use the authorisation they have provided to get basic user details (profile pic/name etc) and post status updates. I don't want to ask a user to login with their account via openId then have to authorise the same account again via oauth to allow my site to publish to their service feed and have to do this for each of the 3 services. Any ideas or issues to this issue Lee

  • Favorite Visual Studio keyboard remappings?

    - by hoytster
    Stack Overflow has covered favorite short-cuts and add-ins, optimizations and preferences -- great topics all. If this one has been covered, I can't find it -- so thanks in advance for the link. What are your favorite Visual Studio keyboard remappings? Mine are motivated by the fact that I'm a touch-typist. Mouse, function keys, arrow keys, Home, End -- bleh. These are commands I do all day every day, so I've remapped them to sequences I can execute without moving my hands from the home row. The command that is remapped in Tools = Customize = [Keyboard] is shown in parentheses. I'm 100% positive that there are better remappings than these, so please post yours! Please include the command; oft times, figuring it out is a challenge. -- Hoytster Running the app and operating the debugger Ctrl+Q + Ctrl+R Run the application, in debug mode (Debug.Start) Ctrl+Q + Ctrl+Q Quit (stop) the application (Debug.StopDebugging) Ctrl+T Toggle a breakpoint at the current line (Debug.ToggleBreakpoint) Ctrl+K + Ctrl+I Step Into the method (Debug.StepInto) Ctrl+K + Ctrl+O Step Out of the method (Debug.StepOut) Ctrl+N Step over the method to the Next statement (Debug.StepOver) Ctrl+K + Ctrl+C Run the code, stopping at the Cursor position (Debug.RunToCursor) Ctrl+K + Ctrl+E Set then next statement to Execute (Debug.SetNextStatement) Navigating the code Ctrl+S Move a character LEFT (Edit.CharLeft) Ctrl+D Move a character RIGHT (Edit.CharRight) Ctrl+Q + Ctrl+S Move to the LEFT END of the current line (Edit.LineStart) Ctrl+Q + Ctrl+D Move to the RIGHT END of the current line (Edit.LineEnd) Ctrl+E Move a line UP (Edit.LineUp) Ctrl+X Move a line DOWN (Edit.LineDown) Ctrl+K + Ctrl+K Toggle (add or remove) bookmark (Edit.ToggleBookmark) Ctrl+K + Ctrl+N Move to the NEXT bookmark (Edit.NextBookmark) Ctrl+K + Ctrl+P Move to the PREVIOUS bookmark (Edit.PreviousBookmark) Ctrl+Q + Ctrl+W Save all modified Windows (File.SaveAll) Ctrl+L Find the NEXT instance of the search string (Edit.FindNext) Ctrl+K + Ctrl+L Find the PREVIOUS instance of the search string (Edit.FindPrevious) Ctrl+Q + Ctrl+L Drop down the list of open files (Window.ShowEzMDIFileList) The last sequence is like clicking the downward-facing triangle in the upper-right corner of the code editor window.

  • How can I write a Template.pm filter to generate PNG output from LaTeX source code?

    - by Sinan Ünür
    I am looking for a way of generating PNG images of equations from LATEX source code embedded in templates. For example, given: [% FILTER latex_display ] \begin{eqnarray*} \max && U(x,y) \\ \mathrm{s.t.} && p_x x + p_y y \leq I \\ && x \geq 0, y \geq 0 \end{eqnarray*} [% END %] I would like to get the output: <div class="latex display"><img src="equation.png" width="x" height="y"></div> which should ultimately display as: I am using ttree to generate documents offline. I know about Template::Plugin::Latex but that is geared towards producing actual documents out of LATEX templates. Any suggestions?

  • High level command line program for burning CDs and DVDs?

    - by stickmangumby
    I'm sick of screwing around trying to script a clean solution to burn multiple files and folders to CDs and DVDs with wodim, growisofs and genisoimage. I'm looking for a high level command line program that uses sensible defaults and takes arguments something like this: [program-name] [cd|dvd] /path/to/dir1/ /path/to/dir2/ /path/to/file ... It should then do all the low level copying and ISO generation transparently and just burn the damn disk! Does anyone have any suggestions? I've looked at several programs but it seems there are too many choices to trawl through and not enough information about them online. Thanks :)

  • How to correctly calculate address spaces?

    - by user337308
    Below is an example of a question given on my last test in a Computer Engineering course. Anyone mind explaining to me how to get the start/end addresses of each? I have listed the correct answers at the bottom... The MSP430F2410 device has an address space of 64 KB (the basic MSP430 architecture). Fill in the table below if we know the following. The first 16 bytes of the address space (starting at the address 0x0000) is reserved for special function registers (IE1, IE2, IFG1, IFG2, etc.), the next 240 bytes is reserved for 8-bit peripheral devices, and the next 256 bytes is reserved for 16-bit peripheral devices. The RAM memory capacity is 2 Kbytes and it starts at the address 0x1100. At the top of the address space is 56KB of flash memory reserved for code and interrupt vector table. What Start Address End Address Special Function Registers (16 bytes) 0x0000 0x000F 8-bit peripheral devices (240 bytes) 0x0010 0x00FF 16-bit peripheral devices (256 bytes) 0x0100 0x01FF RAM memory (2 Kbytes) 0x1100 0x18FF Flash Memory (56 Kbytes) 0x2000 0xFFFF

  • SQL Server catch error from extended stored procedure

    - by haxelit
    Hello I have an extended stored procedure that sends an error message. srv_sendmsg(pSrvProc, SRV_MSG_ERROR, errorNum, SRV_FATAL_SERVER, 1, NULL, 0, (DBUSMALLINT) __LINE__, buff, SRV_NULLTERM); I've set the severity to SVR_FATAL_SERVER just as a test to see if I can cause the message to throw an exception in the sql. In my SQL i'm doing: BEGIN TRY EXEC dbo.xp_somethingCool SET @Error = @@ERROR END TRY BEGIN CATCH PRINT 'AN Error occoured!' SELECT ERROR_NUMBER() AS ErrorNumber ,ERROR_MESSAGE() AS ErrorMessage; END CATCH I would think that when my xp sends the error message the tsql would catch the error and select the error_number and error_message. Instead what ends up happening is that the xp sends the message and the T-SQL continues on its way like nothing happened. The @@Error variable doesn't get set either. So I was wondering if there was any trick to getting SQL to catch an error from an XP ? Thanks, Raul

  • Rails accepts_nested_attributes_for callbacks

    - by Rabbott
    I have two models Ticket and TicketComment, the TicketComment is a child of Ticket. ticket.rb class Ticket < ActiveRecord::Base has_many :ticket_comments, :dependent => :destroy, :order => 'created_at DESC' # allow the ticket comments to be created from within a ticket form accepts_nested_attributes_for :ticket_comments, :reject_if => proc { |attributes| attributes['comment'].blank? } end ticket_comment.rb class TicketComment < ActiveRecord::Base belongs_to :ticket validates_presence_of :comment end What I want to do is mimic the functionality in Trac, where if a user makes a change to the ticket, and/or adds a comment, an email is sent to the people assigned to the ticket. I want to use an after_update or after_save callback, so that I know the information was all saved before I send out emails. How can I detect changes to the model (ticket.changes) as well as whether a new comment was created or not (ticket.comments) and send this update (x changes to y, user added comment 'text') in ONE email in a callback method?

  • Ruby on Rails: reducing complexity of parameters in a RESTFul HTTP POST request (multi-model)

    - by randombits
    I'm using cURL to test a RESTFul HTTP web service. The problem is I'm normally submitting a bunch of values normally like this: curl -d "firstname=bob&lastname=smith&age=25&from=kansas&someothermodelattr=val" -H "Content-Type: application/x-www-form-urlencoded" http://mysite/people.xml -i The problem with this is my controller will then have code like this: unless params[:firstname].nil? end unless params[:lastname].nil? end // FINALLY @person = People.new(params[:firstname], params[:lastname], params[:age], params[:from]) etc.. What's the best way to simplify this? My Person model has all the validations it needs. Is there a way (assuming the request has multi-model parameters) that I can just do: @person = People.new(params[:person]) and then the initializer can take care of the rest?

  • How do I fix this NameError?

    - by Kyle Kaitan
    I want to use the value v inside of an instance method on the metaclass of a particular object: v = ParserMap[kind][:validation] # We want to use this value later. s = ParserMap[kind][:specs] const_set(name, lambda { p = Parser.new(&s) # This line starts a new scope... class << p define_method :validate do |opts| v.call(self, opts) # => NameError! The `class` keyword above # has started a new scope and we lost # old `v`. end end p }) Unfortunately, the class keyword starts a new scope, so I lose the old scope and I get a NameError. How do I fix this?

  • How can I convert videos for Sony Xperia U on my Linux box?

    - by Konstantin
    I would like to send a few videos for my girlfriend, but I would ensure they are playable on her mobile phone. I want to carry out the encoding tasks on my Arch Linux box, because my PC is a low end. I can use only ffmpeg or mencoder or other CLI tool. She can play youtube videos but I don't want to upload such videos to youtube. Are there any presets for specific mobile phones? And when she simply clicks a video direct link will it play directly on the cellphone or should I embed it in a html5 / flash player, like on youtube?

  • LAN speeds and firewall/switch connections

    - by microchasm
    I have a small network with about ten users. All workstations flow into a Dell PowerConnect 3424 which then has a single link to a SonicWALL firewall and from there to a cable modem. More important than internet connectivity is speed between machines (specifically a Windows Server box on the LAN which everyone uses simultaneously). I believe the 3424 has gigabit connections, but they look like they're for stacking. Is there a way to test the speeds on the LAN to see where the speeds are at? Is there any low-hanging fruit insofar as increasing speeds?

  • Type mismatch in expression in Delphi 7 on SQL append

    - by Demonick
    I have a code, that checks the current date when a form is loaded, performs a simple calculation, and appends a SQL in Delphi. It works on Windows 7 with Delphi 7, and on another computer with Xp, but doesn't on 3 other computers with Xp. When the form is loaded it shows a "Type mismatch in expression", and points to the line after the append. What could be the problem? procedure TfmJaunumi.FormCreate(Sender: TObject); var d1, d2: TDate; begin d1:= Date; d2:= Date-30; With qrJaunumi do begin Open; SQL.Append('WHERE Sanem_datums BETWEEN' + #39 + DateToStr(d1) + #39 + 'AND' + #39 + DateToStr(d2) + #39); Active := True; end; end;

  • 912 stream processor available in OpenCL

    - by tugrul büyükisik
    I am thinking of assembling this system: AMD CPU (A8-3870 APU which has Radeon HD 6550D inside: 400 stream processors:xxx GFLOPS) nearly 110$ AMD Graphics card: HD 7750 (512 stream processors:819 GFLOPS peak performance) nearly 170$ Appropriate ram (1600MHz bus) Mainboard What GFLOPS level can I reach as a stable mode with using OpenCL and similar programs? Can I use all 912 stream processors at the same time? I am not trying to do a VS question. I need to know what could be better for scientific computing (%75 of the time) and gaming (%25 of the time) because I have a low budget. With "scientific calculations" I mean fluid dynamics/solid state physics simulating; with games I mean those that need openCL and PhysX.

  • How do I get 480i resolution for an external monitor in Windows 7?

    - by Carson Myers
    I'm trying to get a laptop video signal to my really old television, so that I can play movies on it. But the TV won't accept the video signal. I found the manual online, and apparently the output has to be 480i. But I don't know how to do that -- Windows 7 will only let me set the resolution down to 800x600. Even if I get it down to 640x480- is that 480i or 480p? How do I tell the difference? How do I switch between them? How do I get the resolution down so low in the first place?

  • How do I use CSS transformations to slide a div on screen?

    - by Colen
    Hi, My web page has two divs on it, A and B. Div A is visible, Div B is hidden. When the user clicks a link in div A, I want to "slide" div A off screen (leaving via the left edge), and slide div B on screen (entering via the right edge). I've found that jquery animations are very slow on the ipad, so I want to use the webkit CSS animations instead, which I believe are rendered in hardware. How do I do this?

  • Mongomapper - unit testing with shoulda on rails 2.3.5

    - by egarcia
    I'm trying to implement shoulda unit tests on a rails 2.3.5 app using mongomapper. So far I've: Configured a rails app that uses mongomapper (the app works) Added shoulda to my gems, and installed it with rake gems:install Added config.frameworks -= [ :active_record, :active_resource ] to config/environment.rb so ActiveRecord isn't used. My models look like this: class Account include MongoMapper::Document key :name, String, :required => true key :description, String key :company_id, ObjectId key :_type, String belongs_to :company many :operations end My test for that model is this one: class AccountTest < Test::Unit::TestCase should_belong_to :company should_have_many :operations should_validate_presence_of :name end It fails on the first should_belong_to: ./test/unit/account_test.rb:3: undefined method `should_belong_to' for AccountTest:Class (NoMethodError) Any ideas why this doesn't work? Should I try something different from shoulda? I must point out that this is the first time I try to use shoulda, and I'm pretty new to testing itself.

  • Drupal Views how to filter items overlapping a date range

    - by Marcos Buarque
    Hi, in Drupal I have used CCK to add a datetime field to my custom data type. It inserts start date and end date fields. That is what I want. Now, I want Views to filter and show only the items that have the daterange (start date and end date) overlapping today's date. Any ideas on how to set it up on Views? What I think is strange is that the date fields of my custom content type don't seem to appear on the Views list when I am trying to add a filter. Thanks.
