As some of us have noted, parse.com will be shut down in January 2017. In the current version of parse4cn1, all requests go to https://api.parse.com, using the constant ParseConstants.API_ENDPOINT. Will it be possible to supply a custom URL here, pointing to a different Parse Server? If not, can I build parse4cn1 from source myself? Or should I be looking for an alternative to Parse?
See these related questions:
Will Parse4cn1 still work after Parse server retirement?
parse4cn1 has some issue when working with Node JS and parse-server open source
I now have some time available and intend to make the change you proposed within the coming month or so and make a release that is compatible with the open source Parse server. If that's too late for you, consider making the changes yourself and contributing back via a Github pull request. The Contributing section of the parse4cn1 repo provides useful tips.
Regarding looking at Parse alternatives, that's a decision you'll have to make yourself based on your needs and timeline. My gut feeling is that the Open Source Parse Server will mature and grow in features in the months leading up to the official retirement of Parse.com.

I'm working on an app written in Codename One together with the parse4cn1 library, the combination of which is a real pleasure to use. However, I need support for a few things in parse4cn1 that are not implemented, most importantly ACL and was wondering if Chidiebere has any hints on how to do this (e.g. how did you implement parse4cn1 yourself - from scratch or copying the open source Parse SDK for Android)? If I manage to do something of a decent quality I will try to share back. Thanks in advance
I never got around implementing ACLs (it's still on the TODO list). parse4cn1's interface closes resembles the Parse Android SDK interface and I'll like it to stay that way for convenience. In this case, the interface of interest would be the ParseACL which is documented here.
The actual implementation will need to be done via REST API calls.
Things to bear in mind:
We use the Android SDK API simply for defining methods and signatures for the corresponding class in ParseACL but do not use the SDKs for anything can be be done via REST.
By design, any calls requiring the master key will not be supported in parse4cn1 due to security considerations. If really needed, the functionality should be exposed via server-side cloud code.
Pull requests without unit tests for the added functionality or breaking existing tests will be rejected.
See also the Contributions section of the parse4cn1 github repo.
Good luck with your implementation and I hope to see a PR from you soon ;)
It was implemented from a Java port on top of the REST API's here but was later modified to use the SDK's to allow things like push (which are now no longer relevant).
In the past I just contributed pull a request to the project to get the fixes/features I needed. It was really easy to work with and compile.
Is there a way to have one product definition and have it publish to multiple sites? I am looking for this ability specifically in DNN or Umbraco, either with free or paid extensions. I did install both the platforms and played with the free extensions and looked for any extension offering such functionality but did not find one. Any links or pointers are highly appreciated!
I had looked up for this info in many places before reaching over to the expert pool here, hoping to get some hints;
In umbraco there is the built in /base extension (http://our.umbraco.org/wiki/reference/umbraco-base) which enables you to access product data that is maintained in Umbraco from other websites. Base is REST-ish so the implementation is well documented - you can access the data as XML or JSON (Returning Json instead of XML with Umbraco Base).
Also as the implementation is REST-ish the other websites that consume the content maintained in the core site could be written in anything that can consume a REST feed eg html & javascript.
It's not 100% clear to me what setup you're after, but if you're looking to set up a traditional Authoring/Delivery configuration - one of the few paid offerings Umbraco has is called Courier. It's a very reasonably priced (~$135USD,/99EUR) deployment manager that handles syncing content between two sites, i.e., Authoring and a Delivery server.
It's a very smart tool that manages content, configuration, and dependencies. It's neat and also supports a great open-source project!
If you're looking to setup something more like a centralized product database that is used by many sites - amelvin is on good pointer with BASE. They have a nice api where you may also set up your own webservice (beyond their own webservice functaionality!).
If you need this centralized product data to notify the other sites to update their caches - i encourage you to look into the 'distributedCall' functionality.
There's a bit of documentation on distributed calls in this load-balancing tutorial that may help understand the concept a bit better.
...Hope this helps get pointed in the right direction.
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.
Is there a simple and automatic way of checking if a visitor to my website (written in asp.net) is using the latest version of his browser? This would allow me to display a message to inform them that they're running an old version and that they might want to upgrade.
My website is tested on most broswers but I don't test old versions (such as Internet Explorer 6 etc). When one of my visitors is using such an old version, basically, I would like to encourage (not force) them to upgrade.
Of course I could do this myself by getting the version of the browser and look it up in my database but I don't want to have to maintain a 'browser version' database myself.
Any ideas?
Speaking as a user of websites, if I come across a site that advised me to upgrade my browser then that would be an immediate black mark against that site.
I might not be able to upgrade (if I'm accessing from a corporate network for example); I might have a specific reason for using a particular version (if I'm a web developer wanting to ensure compatibility with my user community for example).
So personally, I would say that a blanket disclaimer that you don't test this site on earlier versions would be the way to go. That's quite apart from the technical challenge of what you want to do.
Edit: as Yeti points out, however valid my concerns, I don't answer the question directly. This is done in Pace's answer, and the w3schools resource he points to gives you what you need to do this on the client side.
