Managing configurations with object graphs

***
This post is basically a pitch I send to folks whom I think will be interested in a modern approach to configuration management. I am posting it here so I can refer people to it without sending them a long email.
***

One of the features of the Solvent (formerly HiveMind) platform is a smart object technology that solves the problem of dealing with hierarchical configuration information often represented in formats Like YAML,JSON, Java Properties,XML...etc

The smart object technology allows developers/users to directly construct object graphs of any complexity. Once you have the actual object graph you can reverse the process back to representation in any one of the formats mentioned above.
 

I have setup a demo instance for trying it out @ http://demo.crudzilla.com:7000

Login with login info I sent you.

Be nice, you have full system access :)

To see an example representing the AWS IP list (https://ip-ranges.amazonaws.com/ip-ranges.json):

Navigate to: /com/crudzilla/betaApp/web/aws/index.ins

This is what a smart object looks like, the cool thing is that you can combine smart objects to compose any complex object graph and you use the file system to organize the smart objects.
Once you have your object graph you can serialize it to any suitable format as the included examples show:


http://demo.crudzilla.com:7000/betaApp/crud-appserver/aws/yaml/
http://demo.crudzilla.com:7000/betaApp/crud-appserver/aws/json/
http://demo.crudzilla.com:7000/betaApp/crud-appserver/aws/properties/
http://demo.crudzilla.com:7000/betaApp/crud-appserver/aws/xml/


This approach is quite powerful, beyond its use for configuration, it can be used to allow non-technical users to handle certain data management tasks where a developer need not be involved. For instance a developer working on an e-commerce site can offload product catalog management to business users who will use this feature to manage the catalog, while the developer focus on the application.

Reactive and Component Frameworks for "Old Fart" Programmers

One of the great challenges for experienced developers when confronted with new concepts is being able to map one's existing knowledge to the new concept. As they say, there is nothing new under the sun, that is often more true for new development methodologies.

Even when new jargon is brought to bear on new methodologies, often upon closer inspection you recognize that it is something that you already know that is being described in a new way (unfortunately sometimes in a convoluted way to make it seem new).

Reactive/Component UI/UX frameworks are one such development, while their particular implementations may be new and novel, almost all of the underlying concepts are not new.


This is hardly a thorough presentation of Reactive/Component frameworks, but rather an attempt to fill in some gaps for developers who have experience but might find themselves confused by some of these new kids on the block.

The top 3 reactive component frameworks being React, Angular and Vue. All of the…

The feds need to shutdown the bitcoin scam now.

I live in Baltimore, let's say I have some hypothetical friends who are always looking for a good hustle.

Now imagine if my friends got together for a new get-rich-quick-scheme, the scheme is very simple. They invent something called cracken (bitcoins) that they start selling on a few blocks in Hamsterdam.

The way you get crackens is to do laps around the blocks in Hamsterdam. Initially when the scheme was setup, you could get a whole lot of crackens by merely doing a few strolls around the block. Needless to say my friends made out like bandits, since, after all they created the scheme and could take advantage of the first-come-first-serve rules.

Unfortunately for the rest of the hood, the number of laps required to get the same number of crackens keeps going up and after a while even the fittest folks in the neighborhood cannot do the lapse required to earn crackens.

Cracken mania takes hold and infects the whole city. Those with crackens start trading these crackens for exor…

Javascript for Java (ie JVM)

One of the exciting developments in the recent JDK-8 release is the integration of the Nashorn Javascript engine.

Vertically integrated Javascript web application development

Nashorn allows for the development of applications in the Javascript language on the JVM, what this means in general is that you can build both the frontend and backend of web applications in the same language, ie Javascript.


What's in it for you

Vertically integrated Javascript development has great appeal as can be attested to by the popularity of NodeJS. For the JVM this offers massive opportunity. Currently a lot of businesses with JVM infrastructure are constrained by their inability to staff for their Java developer needs. With technology such as Nashorn, a JVM shop doesn't need to demand Java skills, instead as a JVM shop you can hire developers already skilled in Javascript and put them to work building your business applications while still taking full advantage of the massive JVM technology platfor…
