  • RegEx - How To Insert String Before File Extension

    - by st4ck0v3rfl0w
    Hi All, How would I insert "_thumb" into files that are being dyanmically generated. For example, I have a site that allows users to upload an image. The script takes the image, optimizes it and saves to file. How would I make it insert the string "_thumb" for the optimized image? I'm currently saving 1 version of the otpimized file. ch-1268312613-photo.jpg I want to save the original as the above string, but want to append, "_thumb" like the following string ch-1268312613-photo_thumb.jpg

  • QtCreator on linux: 32-bits vs. 64-bits.

    - by Claire Huang
    My laptop is 64-bits, so when I start to use Qt, I chose 64-bit QtCreator. Now I'm facing a problem, I wish that the executable files I generated are runnnable on 32-bit linux system. Can I set QtCreator to generate 32-bit executable files? So that I can decide I want to generate 32-bit ones or 64-bit ones. I don't want to install another 32-bit QtCreator <.

  • PerlIO in Windows PowerShell and CMD.exe

    - by Evan Carroll
    Apparently, a Perl script I have results in two different output files depending on if I run it under Windows PowerShell, or cmd.exe. The script can be found at the bottom of this question. The file handle is opened with IO::File, I believe that PerlIO is doing some screwy stuff. It seems as if under cmd.exe the encoding chosen is much more compact encoding (4.09 KB), as compared to PowerShell which generates a file nearly twice the size (8.19 KB). This script takes a shell script and generates a Windows batch file. It seems like the one generated under cmd.exe is just regular ASCII (1 byte character), while the other one appears to be UTF-16 (first two bytes FF FE) Can someone verify and explain why PerlIO works differently under Windows Powershell than cmd.exe? Also, how do I explicitly get an ASCII-magic PerlIO filehandle using IO::File? Currently, only the file generated with cmd.exe is executable. The UTF-16 .bat (I think that's the encoding) is not executable by either PowerShell or cmd.exe. BTW, we're using Perl 5.12.1 for MSWin32 #!/usr/bin/env perl use strict; use warnings; use File::Spec; use IO::File; use IO::Dir; use feature ':5.10'; my $bash_ftp_script = File::Spec->catfile( 'bin', 'dm-ftp-push' ); my $fh = IO::File->new( $bash_ftp_script, 'r' ) or die $!; my @lines = grep $_ !~ /^#.*/, <$fh>; my $file = join '', @lines; $file =~ s/ \\\n/ /gm; $file =~ tr/'\t/"/d; $file =~ s/ +/ /g; $file =~ s/\b"|"\b/"/g; my @singleLnFile = grep /ncftp|echo/, split $/, $file; s/\$PWD\///g for @singleLnFile; my $dh = IO::Dir->new( '.' ); my @files = grep /\.pl$/, $dh->read; say 'echo off'; say "perl $_" for @files; say for @singleLnFile; 1;

  • How to distribute java components for developers to use?

    - by coder
    I am not sure how to put the correct title. but here is the brief explanation. With Microsoft .NET, i created a server side custom control using C# to be used in ASP.NET pages. I distribute the DLL generated as a component. developers will include that and use in their ASP.NET project. Likewise, how can i do for Java based web components for to use with JSP or JSF or any other java web frameworks?

  • Authlogic OpenID: Fetching E-Mail from Provider.

    - by Shripad K
    This is a really weird problem: I have set up the authlogic_openid_selector_example app. When i register, the email id is not returned by the openid provider the first time. But if i delete the account and register again, the email id is returned. But this doesn't seem to be happening in the example hosted here: http://big-glow-mama.heroku.com/. How do i fix this problem? Has this got to do with caching? I have hosted my version of the app here: http://pingauthtest.heroku.com/ I guess the author of authlogic_openid_selector_example app (@holden) has forgotten to commit new changes. :) I looked at my development log and the first time the provider doesn't return the openid.ext1.value.ext0 which contains the email id. This is returned the second time only after having deleted the account first. Edit: This is some extra info for debugging: THIS IS WHEN IT REGISTERS: OpenIdAuthentication::Association Load (5.3ms) SELECT * FROM "open_id_authentication_associations" WHERE ("open_id_authentication_associations"."server_url" = E'https://www.google.com/accounts/o8/ud') Generated checkid_setup request to https://www.google.com/accounts/o8/ud with assocication AOQobUde_9BUnQsk91rb_Sf9tguJ-S7Gpkwahc-nvDGDYAC8nphisNqu Redirected to https://www.google.com/accounts/o8/ud? openid.assoc_handle=AOQobUde_9BUnQsk91rb_Sf9tguJ-S7Gpkwahc-nvDGDYAC8nphisNqu &openid.ax.mode=fetch_request &openid.ax.required=ext0 &openid.ax.type.ext0=http%3A%2F%2Faxschema.org%2Fcontact%2Femail &openid.claimed_id=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select &openid.identity=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select &openid.mode=checkid_setup &openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0 &openid.ns.ax=http%3A%2F%2Fopenid.net%2Fsrv%2Fax%2F1.0 &openid.ns.sreg=http%3A%2F%2Fopenid.net%2Fextensions%2Fsreg%2F1.1 &openid.realm=http%3A%2F%2Flocalhost%3A3000%2F &openid.return_to=http%3A%2F%2Flocalhost%3A3000%2Faccount%3Ffor_model%3D1%26_method%3Dpost%26open_id_complete%3D1 &openid.sreg.required=email Completed in 3574ms (DB: 14) | 302 Found [http://localhost/account] THIS IS WHEN IT USES SESSIONS: OpenIdAuthentication::Association Load (5.3ms) SELECT * FROM "open_id_authentication_associations" WHERE ("open_id_authentication_associations"."server_url" = E'https://www.google.com/accounts/o8/ud') Generated checkid_setup request to https://www.google.com/accounts/o8/ud with assocication AOQobUde_9BUnQsk91rb_Sf9tguJ-S7Gpkwahc-nvDGDYAC8nphisNqu Redirected to https://www.google.com/accounts/o8/ud? openid.assoc_handle=AOQobUde_9BUnQsk91rb_Sf9tguJ-S7Gpkwahc-nvDGDYAC8nphisNqu &openid.ax.mode=fetch_request &openid.claimed_id=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select &openid.identity=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select &openid.mode=checkid_setup &openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0 &openid.ns.ax=http%3A%2F%2Fopenid.net%2Fsrv%2Fax%2F1.0 &openid.ns.sreg=http%3A%2F%2Fopenid.net%2Fextensions%2Fsreg%2F1.1 &openid.realm=http%3A%2F%2Flocalhost%3A3000%2F &openid.return_to=http%3A%2F%2Flocalhost%3A3000%2Fuser_session%3Ffor_session%3D1%26_method%3Dpost%26open_id_complete%3D1 Completed in 2708ms (DB: 15) | 302 Found [http://localhost/user_session]

  • running jython bytecode using java

    It looks like I'm missing something. When using Jython to run my Python code in Java, Java bytecode files are generated (test.py - [email protected]). Can I run these classes directly using java? In other words, I want to make this: $ java test@py [additional cp args] work. The intent: writing Python code and not having to give away source code.

    I have a huge .bib file generated automatically from Papers for Mac and all the capitalization in the .bib is already the way I want it, but it doesn't have {} brackets on word like RNA. Is there a way to force BibTeX to keep the capitalization rather than change some words to lowercase?

  • Odd ActiveRecord model dynamic initialization bug in production

    - by qfinder
    I've got an ActiveRecord (2.3.5) model that occasionally exhibits incorrect behavior that appears to be related to a problem in its dynamic initialization. Here's the code: class Widget < ActiveRecord::Base extend ActiveSupport::Memoizable serialize :settings VALID_SETTINGS = %w(show_on_sale show_upcoming show_current show_past) VALID_SETTINGS.each do |setting| class_eval %{ def #{setting}=(val); self.settings[:#{setting}] = (val == "1"); end def #{setting}; self.settings[:#{setting}]; end } end def initialize_settings self.settings ||= { :show_on_sale => true, :show_upcoming => true } end after_initialize :initialize_settings # All the other stuff the model does end The idea was to use a single record field (settings) to persist a bunch of configuration data for this object, but allow all the settings to seamlessly work with form helpers and the like. (Why this approach makes sense here is a little out of scope, but let's assume that it does.) Net-net, Widget should end up with instance methods (eg #show_on_sale= #show_on_sale) for all the entires in the VALID_SETTINGS array. Any default values should be specified in initialize_settings. And indeed this works, mostly. In dev and staging, no problems at all. But in production, the app sometimes ends up in a state where a) any writes to the dynamically generated setters fail and b) none of the default values appear to be set - although my leading theory is that the dynamically generated reader methods are just broken. The code, db, and environment is otherwise identical between the three. A typical error message / backtrace on the fail looks like: IndexError: index 141145 out of string (eval):2:in []=' (eval):2:inshow_on_sale=' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2746:in send' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2746:inattributes=' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2742:in each' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2742:inattributes=' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2634:in `update_attributes!' ...(then controller and all the way down) Ideas or theories as to what might be going on? My leading theory is that something is going wrong in instance initialization wherein the class instance variable settings is ending up as a string rather than a hash. This explains both the above setter failure (:show_on_sale is being used to index into the string) and the fact that getters don't work (an out of bounds [] call on a string just returns nil). But then how and why might settings occasionally end up as a string rather than hash?

One of the Tables is People, I want to override the person.Equals() method but I'm unsure where to go to make such a change since the Person object is auto-generated and I don't even see where that autogen code resides. I know how to override Equals on a hand made object, its just where to do that on an autogen one.
