  • Simple Ruby Command Line Question

    - by aronchick
    Um - I feel like an idiot, but.... ruby -e '3+5' Outputs nothing (Windows 7, Ruby 1.8.7, Cygwin or Git Bash). What am I missing? Extra credit - will this also allow the extra cool bundle (stolen from TextMate) Execute and Update # = markers to work properly? EDIT Ok that worked, and I'll accept the answer, but e-texteditor still doesn't work with that really cool bundle. Too bad.

  • A way to automatically organize #imports in Xcode

    - by Arrel
    I love the "Organize Imports" command in Eclipse to implicitly add and remove classes imported into a source file (as in Java or ActionScript). Is there a command in Xcode to update the #import directives at the top of.m Objective-C files based on the classes referenced within the file?

  • How to change windows exe file's icon in linux without wine?

    - by zenpoy
    I know I can use ResHacker to change a resource from windows and I know I can use ResourceUpdate function to do the same problematically (again in windows). My problem is that I have to update the icon of a windows exe file in linux, without using wine. (the reason for not using wine is that this process should run on an automation server that change the files and sign them). I don't know even where to start from.

  • Capture Video of Android's Screen

    - by Taranfx
    Forget screenshots, is it posible to capture a video of the running application in android? Rooted or non-rooted, I don't care, I want atleast 15fps. Update: I don't want any external hardware. The intent is to make it perfectly portable and every frame is captured within Android OS. If it crosses the boundaries of the app sdk, I'm willing to go to OS level modifications but I would need a starting point.

  • Store Observer not being called always

    - by Nixarn
    Has anyone else here experienced problems with their Store Observer class not being called always when the user for instance cancels a request (or purchases something) We just had our update that brought in app purchases go live last night, and before that we had obviously tested everything tons of times against the Sandbox and everything was working fine. Now however, when the update went live in a real environment we keep getting issues with the store. For instance, in a freshly booted iPhone / iPod, the first time you run the app, if you then try to make a purchase and then immediately cancel it from the first dialog, it seems as if the callback for the cancel is not getting called. If you then restart the app it seems as if it always works after that, or at least. Same thing with other callbacks, seems as if our store observer isn't listening as the callbacks aren't being registered on the phone. One example of this is if you purchase something, then nothing will happen (if this is the first time the app is launched at least). You get the purchase successful dialog from the app store but it seems as if our own code isn't called. If you then quit the app and restart it the callback gets called. Same problem happens if you for instance try to start a request to download all previous purchases and then immediately cancel it as the first dialog pops up, if you do that then the callback for a failed restore is not called, until you then restart the app and try it again, then it always seems to work. The way we have implemented our store observer is by creating a custom class that's implements the SKPaymentTransactionObserver interface. @interface StoreObserver : NSObject<SKPaymentTransactionObserver> In the class we have implemented the following methods: - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions - (void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue - (void)paymentQueue:(SKPaymentQueue *)queue restoreCompletedTransactionsFailedWithError:(NSError *)error The way our restore process works is that if you tap on the button that allows you to download all we simply run the restoreCompletedTransactions code as follows: [[SKPaymentQueue defaultQueue] restoreCompletedTransactions]; However, the callback, restoreCompletedTransactionsFailedWithError, which has been implemented in the store observer, does not always get called when we try to cancel the request. This happens when you boot the iPhone / iPod and try this for the first time. If you after that restart the app everything works fine. The StoreObserver class is created when our app is launched, just by running the following code: pStoreObserver = [[StoreObserver alloc] init]; [[SKPaymentQueue defaultQueue] addTransactionObserver:pStoreObserver]; Has anyone else had any similar experiences? Or does anyone have any suggestions on how to solve this? As I said, in the sandbox environment everything was working fine, no issues whatsoever, but now once it's gone live we're experiencing these.

  • MySQL: LOAD DATA reclaim disk space after delete

    - by Michael
    I have a DB schema composed of MYISAM tables, i am interested to delete old records from time to time from some of the tables. I know that delete does not reclaim the memory space, but as i found in a description of DELETE command, inserts may reuse the space deleted In MyISAM tables, deleted rows are maintained in a linked list and subsequent INSERT operations reuse old row positions. I am interested if LOAD DATA command also reuses the deleted space? UPDATE I am also interested how the index space reclaimed?

  • new items on GRUB screen in ubuntu/linux

    - by artsince
    I regularly update my ubuntu (10.04), and new minor versions keep accumulating on the GRUB screen. Right now I have 5 different versions listed on the GRUB, even though I always select the latest version to work with. Am I supposed to do anything to get rid of the old version references? Do these old versions affect disk space/performance?

  • Why is this line breaking Rails with Passenger on DreamHost?

    - by Frew
    Ok, so I have a Rails app set up on DreamHost and I had it working a while ago and now it's broken. I don't know a lot about deployment environments or anything like that so please forgive my ignorance. Anyway, it looks like the app is crashing at this line in config/environment.rb: require File.join(File.dirname(__FILE__), 'boot') config/boot.rb is pretty much normal, but I'll include it here anyway. # Don't change this file! # Configure your app in config/environment.rb and config/environments/*.rb RAILS_ROOT = "#{File.dirname(__FILE__)}/.." unless defined?(RAILS_ROOT) module Rails class << self def boot! unless booted? preinitialize pick_boot.run end end def booted? defined?

  • Authlogic: passwords saved in the DB are not working as expected.

    - by user570459
    Hello everyone, Im having trouble with authlogic on my production server. Im able to update passwords in the database but when i try to validate a user using the new password, the validation fails. Please check the below console output. Notice how the salt and crypted_password fields get update before and after the new password is saved. The issue is only on my production server (running passenger). Everything works fine on my development machine. => #<User id: 3, login: "saravk", email: "[email protected]", crypted_password: "9bc86247105e940bb748ab680c0e77d9c44a82ea", salt: "WdVpQIdwl68k8lJWOU"> irb(main):003:0> u.password = "kettik123" => "kettik123" irb(main):004:0> u.password_confirmation = "kettik123" => "kettik123" irb(main):005:0> u.save! => true irb(main):006:0> u.valid_password?("kettik123") => true irb(main):007:0> u.reload => #<User id: 3, login: "saravk", email: "[email protected]", crypted_password: "f059007c56f498a12c63209c849c1e65bb151174", salt: "lVmmczhyGE0gxsbV421A"> irb(main):008:0> u.valid_password?("kettik123") => false The authlogic configuration in my User model.. class User < ActiveRecord::Base acts_as_authentic do |c| c.login_field :email c.validate_login_field false c.validate_email_field false c.perishable_token_valid_for = 1.day c.disable_perishable_token_maintenance = true end I use the email field as the main key for the user. Also the email field is allowed to be blank in some cases (eg a facebook user) Also i belive that my schema is proper (in terms of the length of the salt & crypted password fields) create_table "users", :force => true do |t| t.string "login" t.string "email" t.string "crypted_password", :limit => 128, :default => "" t.string "salt", Any help on this would be highly appreciated. Thanks.
