I'm using v1.5.1 but will soon upgrade to 1.6.
What is the difference between embeddedset and linkset? Should one be preferred over the other?
I don't really need linkset for my application, but I am wondering about performance and usability (e.g. is querying/modification harder with embeddedset?)
look at the official documentation about relationship: https://github.com/orientechnologies/orientdb/wiki/Concepts#relationships

I am using expo 39 SDK is it possible to integrate clever tap notif without ejecting it
In theory, you should be able to do this... However in reality, it may be a bit more complicated. Clovertap is quite specific in terms of exact compatibility without ejecting. It seems that there is little documentation out (at the time of this initial post) for compatibility and use cases between the two systems.
Depending on your underlying problem, another solution may actually be to switch over to FirebaseCloudMessaging.
With that said, lets address the asked problem.
You will probably need to dive into the documentation and attempt code to find out the nitty gritty. I would recommend starting with the push notification documentation:
https://docs.expo.io/push-notifications/overview/
https://docs.clevertap.com/docs/push
https://github.com/platanus/angular-restmod seems much clearer to me than restangular but I can't find much info about it - has anyone used it, know of any pitfalls, etc.?
For instance, I can't see support for PATCH for partial updates. Any and all info is welcome.
We are using Angular Restmod in various projects in production and I can tell you it does what it says it does.
Take a look at the issues in Github, there's a lot going on there right now.
I was starting to write a multi-Map JS library, but I see that Mapstraction does that exactly..
I really would like to use Maptraction but it looks a little old (The commit's on GITHUB) (Not a issue if it is still "supported"), also The tutorial page, the Maps do not show up in my browsers.
Any input is highly appreciated.
Thanks
Kim
Depends what your use case is - if you don't want to be tied in to any one map provider and only need standard features then, yes.
Version 2.1 of Mapstraction is currently being prepared (on the release-2.1 branch) which brings some improvements in behavioural consistency across the providers.
Because of the nature of the library development isn't continuous and tends to be reactive to changes in the underlying providers or issues being raised. That said the community is fairly active and you can sign up to the mailing list via the site.
I am currently investigating possible options of a migration framework/tool. I like the idea of ruby migrations on which the above frameworks are based.
So I am asking for your experience, opinions and maybe a comparison between them. Are you using them in production?
thanks for responses. The goal of this question was to get a feeling about which tools is used most in the developer community but it seems that migrations are not a hot topic here.
Anyway, I have decided to go with MigSharp as the codebase seem to be pretty clean and it is quite easy to handle and had build in support for MS SQL CE. Second runner up would have been FluentMigrator where I was not able to produce a working example for compact edition.
Cheers
I use FluentMigrator in production, and am a longtime contributor to FM. I think your question is to general; be more specific. Also, FM has a google group which is fairly active if you want FM information.
FM is derived from migrator.net, as I recall. It uses a fluent-syntax, and supports multiple databases. We have taken some inspiration from rails migrations, but it's definitely not a port. Worth checking out.
One thing I've learned is not to put your migrations in the same assembly as you app code. Separate them into a migration assembly, and use that for migrating your databases.
Also, you should always work on multiple environments to avoid problems with migrations run straight against production. I always have at least a development and production environment, and most of the time there is a testing environment as well.
I use mig#.
It works well, but you will need to have some guidelines for usage - as migrations can get complicated.
We use sequence number on the end of our migrations rather than a date-time stamp. This is because we don't know when the date time stamp was set (when they begun the source code change-set; just before committing; some time inbetween) different developers could use different approaches.
Names such as Migration_0000034.cs give you plenty of space.
At this point, I would stick with migrator.net. I like the promise of FluentMigrator, but it seems to not have any better active development than migrator.net (see the issues and pull requests that have languished on their github site).
There is also no easy way to do an ExecuteScalar(). I'd add it, but I don't want to create my own fork, and I see no reason that a pull request would actually land in the master. (Execute.WithConnection is an Action so it will fire on demand rather than when I need it to fire)
So for me, I'm heading back to migrator.net.
I'm evaluating Backbone.js for keeping data and UI synchronized in my web app. However, much of Backbone's value seems to lie in its use of RESTful interfaces. Though I may add server-side backup in the future, my primary use case involves storing all data offline using HTML5 local storage.
Is Backbone overkill for such a use case? If so, is there a better solution, focused solely on updating UI when data changes, and vice versa? (I'm also looking into Knockout and Javascript MVC.)
EDIT: I'm also now looking into Angular.js and jQuery Data Link.
Backbone.js works just as well with local storage as it does with RESTful queries.
I'm a learn-by-example kind of guy so here are some links to get you started:
Todos, a todo application
that uses local storage and
backbone.js, check out the annotated
source to see how it works.
The localStorage adapter is
all you need to get started, take a
look at the annotated source of
that too.
In the past weeks I have evaluated different solution for a scenario close to yours; being a project done in my personal free time and not being a good Javascript programmer, all I needed was something easy to learn to avoid starting from scratch.
Not surprisingly, I had the same candidate: Backbone.js, Javascript MVC and Knockout.js.
Backbone.js won:
I wasn't be required to follow conventions or replace what was already in place
I've easly hacked in its codebase to understand what wasn't clear from the documentation
I've successfully ignored a large amount of its features that was not interesting for me
It gave acceptable performance on busy pages
It works
Backbone.js is lightweight and relatively magic-free; you will probably use a small subset of its feature but it provieds a solid base to develop your solution.
I know it's been a while but you may want to check out backbone-offline project on github: https://github.com/Ask11/backbone.offline
You can also take a look at AFrameJS. I have created a bare-bones proof of concept note-taking app that works offline using HTML5 WebSQL spec, but also want to create an adapter that uses localStorage as well. My personal opinion (and I am biased) is that using an MVC library of any sorts is going to help you in the long run - the value of libraries such as Backbone, Knockout, and AFrame lie in their ability to reduce the cognitive load of the developer by enforcing a good separation of concerns. Data related functionality reside in models, displaying that data resides in Views, and the glue is kept in Controllers. Separating these three concepts might seem pedantic at first, but the end result is code that is easier to develop, easier to test, easier to maintain, and easier to reuse. A basic tutorial on using AFrameJS can be found on my site at: http://www.shanetomlinson.com/2011/aframejs-tutorial-for-noobs/
