Rails: Faster way to perform updates on many records

阅读更多关于 Rails: Faster way to perform updates on many records

问题 In our Rails 3.2.13 app (Ruby 2.0.0 + Postgres on Heroku), we are often retreiving a large amount of Order data from an API, and then we need to update or create each order in our database, as well as the associations. A single order creates/updates itself plus approx. 10-15 associcated objects, and we are importing up to 500 orders at a time. The below code works, but the problem is it's not at all efficient in terms of speed. Creating/updating 500 records takes approx. 1 minute and

Target API level requirement from late 2018

阅读更多关于 Target API level requirement from late 2018

问题 I don't know if this is a correct place where ask the following: I have read on the google play developer console that : In the second half of 2018, Play will require that new apps and app updates target a recent Android API level. This will be required for new apps in August 2018, and for updates to existing apps in November 2018. This is to ensure apps are built on the latest APIs optimized for security and performance and Google Play will require that new apps target at least Android 8.0

阅读更多关于 Xcode update stuck after updating macOS

问题 After updating macOS, I cannot update XCode anymore: I have been waiting for 2 hours but AppStore does not update. How do I restart the Xcode update process from the beginning? Regards 回答1: A lot of the pain of updating XCode from the App Store can be avoided by downloading the latest version from the Apple Developer website directly (including beta versions if you are into them). Use this Apple Developer link. For more information see this Ask Different answer. 回答2: It is painfully slow when

Update meteor collection without removing or overriding existing fields

阅读更多关于 Update meteor collection without removing or overriding existing fields

I don't know why but if i try to update an existing field using the $set method, any existing fields are replaced in the same context. For example. Say i have an existing collection with the following fields. Name of collection: Ticket {profile: {name: "Test", placement: 1}, requestor: _id} When i attempt to add/update fields to this collection like this: var ticket = Meteor.tickets.findOne({_id: ticketID}); if(ticket){ Meteor.users.update(ticket, { $set: profile: {name: "Test2", new_fields: "value"} }); } The collection gets updated and the name field changes but placement is removed and no

Why are my Xcode plugins (such as clang format) installed with Alcatraz no longer working after updating to new version of Xcode?

阅读更多关于 Why are my Xcode plugins (such as clang format) installed with Alcatraz no longer working after updating to new version of Xcode?

问题 Today I updated to Xcode 6.3.2 and I can't run the Clang code formatting – it seems like it's not even installed. Everytime I update Xcode, I have to reinstall Alcatraz and most of the packages (why btw?) to make them work on the new version of Xcode. This time I reinstalled all packages (like VVDocumenter, Color picker, etc), but the ClangFormat doesn't work – it doesn't even appear in the "Edit" menu. Any idea why? btw. I tried to restart Xcode as well as the Mac itself :) EDIT (Solution):

How to organize code so that we can move and update it without having to edit the location of the configuration file?

阅读更多关于 How to organize code so that we can move and update it without having to edit the location of the configuration file?

问题 The issue that I consider is how to write code that can easily know the location of a required config file and yet is portable, without any edit, from an environment to another. We don't want to edit the location of the configuration file to adapt the code to each new environment, say each time we move the code from a development environment to production. The method should not rely on resources that are not universally available, such as an access to user-defined environment variables or an

Efficient updates of image plots in Bokeh for interactive visualization

阅读更多关于 Efficient updates of image plots in Bokeh for interactive visualization

I'm trying to create a smooth interactive visualization of different slices of a muldimensional array using Bokeh. The data in the slices changes according to the user interaction and thus has to be updated several times per second. I have written a Bokeh app with several small image plots (64x64 values) to show the contents of the slices, and a callback to update the ColumnDataSources when the user interacts with the app. Everything works as expected but I can't get more than 2 or 3 frames per second and I would like to get at least 10 frames. Here is a simplified sample of my code using 16
