#52Granted that dataflow programming (DFP) is probably a bad idea for general-purpose software development, I still think there are some great use cases for it. For example, I think it could be a great fit for business intelligence and data analysis, since DFP really is a pretty natural way to think about data transformation and aggregation, and most people that would not be able to understand a map/reduce function or a…
Enterprise ETL, process automation and service integration is a massive market, it'd be cool to see them buddy up with someone like Mulesoft. I tend to think these kinds of services aren't really suited to general consumers but there's definitely a place for it in the enterprise space.

#53I am elderly enough to remember IRIS Explorer on SGI Workstations way back in the 1990's, when having a 2Gb hard drive was just about unimaginable. Here is a quickly Googled screenshot: http://wwwasdoc.web.cern.ch/wwwasdoc/lhcpp/irisexplorer.gif IRIS Explorer was awesome, but hardware was not really up to the job in those days. There was also a rich market in GIS and other applications that did what you needed so the…
I agree wholeheartedly with being able to go inside the black-boxes, and the transition be smooth.
In NoFlo, one of the the main runtimes for Flowhub, the components are JavaScript/CoffeScript|. They can be viewed and modified from within the UI. The API is pretty simple, and was improved further with NoFlo 0.5.
I'm experimenting with some ideas from the functional and automata/finite-state-machine world on how we can improve things further.
I also think it is important that people can freely chose how much and on what level you use text/code OOP and which level you use nodes/graphs FBP. Embed NoFlo as a DSL for a particular problem area, use as general purpose language, or just as a coordination layer between your high-level modules.

Nah, that is related to GSS stylesheets on the site making use of the matrix3d part of CSS. Unfortunately lots of (expecially Linux) 3D drivers are not exactly up to the task. Edit: as for required login, that isn't needed to play with just the examples.

I can play 3D videogames with lots of advanced shaders and even develop my own, perform very demanding computations on my 8-core machine and watch HD movies and stream from the web, yet I can't easily view a simple home page from the internet? Is this the state of technology in 2014?
Welcome to the "open" web! It is build on "new" technologies such as HTML, CSS and JS.

Sure, there's space for graphical flow-based programming to wire enterprise components together—but there also a slew of established enterprise products occupying that space.

#56Woah, I have no relationship whatsoever with this guys, but I am quite disappointed with the kind of responses in this thread.
In my opinion there should be no destructive critics in any "Show HN" thread.
If you find some mistakes or whatever, you could make a constructive critic, ie: Hey guys, IMHO you should add more info in the landing page, because I am not understanding what your project does.
On the other hand, as someone posted in this thread you could tell them: "You're not the only one who had no clue. [...] And I'm not wasting another second of my time on flowhub.."
Is that the kind of answer that a fellow hacker deserves?? I don't think so.
Remember that people do not post projects at HN only to reach a big audience, but also to get a great feedback from smart people. So before giving impolite answers, we should remember that we are all in the same boat, and the next "Show HN" thread could be your project. Think about the kind of answers you would like to get.
PS:I know that most of the people at HN is great people, but I think this needed to be said today.

How easy is it to examine the underlying abstractions behind connecting one pipe from one icon to another? Depends on the runtime you're talking to. For example MicroFlo on an Arduino behaves quite differently from NoFlo on Node.js In NoFlo each connection is basically connecting an event emitter to an event listener. So, what happens is a JavaScript addEventListener operation.
how do ya'll handle errors? Is this primarily built on Node?
Errors are generally sent as a data packet to an error port (convention), or thrown if there isn't a connection to that.
NoFlo is running in three environments: Node.js, browser, and GNOME's JavaScript env

If you Show HN, and someone takes enough time to give it, that's valuable to you no matter the tone.
"Didn't get it, not wasting any more time" is an incredibly valuable comment to receive because it helps you understand the most common occurrence for your home page, someone landing and immediately moving on. You'd normally never get feedback from that traffic and not know why they bounced. Now the builders know what to fix to increase engagement.
