The General Problem

From: http://xkcd.com/974/

I find that when someone is taking time to do something right in the present, they’re a perfectionist with no ability to prioritize, whereas when someone took time to do something right in the past, they’re a master artisan of great foresight.

Notes on Product Engineering

Panos — Sun, 13 Nov 2011 14:36:02 +0000

Notes from this presentation by Mike Lee (@bmf):

IDEA => (Product Engineering) => PROFIT
Seek not originality… but quality
The product is under the ideas (must find it)
Consider customers: Start at the end by making a commercial
Picking a platform: Platform is culture
Building a team: x platforms => x+1 teams
Test your product: Like enemy – Build what user expects
Shipping is necessity: Plan-Design-ShipOnTime, Shipping a draft = Amateur Mistake
When is ready? “Holy Crap!”

BPMN usage and tips

Are Floating Intermediate Events Valid? The issue is an intermediate event (e.g., message or timer) “floating” in a process or expanded subprocess alongside the regular flow, the one bounded by start and end events. The floating event has a sequence flow out, leading eventually to end event, but no sequence flow in.

When Are Error End Events Legal? Is it valid to end a top-level process in BPMN with an error end event?

Workflow (WF) Screencasts

Panos — Mon, 27 Oct 2008 23:35:08 +0000

Your first sequential workflow
Your first state machine workflow
Running workflows in your .NET applications: Matt covers the basic steps to host workflows in your applications. He covers the basic hosting steps in a console application, then jump in and run a workflow in an ASP.NET application.
Using persistence services in WF: Matt presents the basics of add persistence services into the workflow runtime using code or configuration. Additionally, to show off the power of this feature in Windows WF, he uses two different host processes sharing a persistence store: the first host starts a workflow and then it persists, while the second host picks up the workflow after its configured delay and resumes the processing.
Using the WCF Receive Activity in a workflow: Learn how to use the Receive activity in your workflows to implement WCF services as workflows. In addition, see how to use the WorkflowServiceHost class to host your workflow as a service.
Using the WCF Send activity in Windows Workflow Foundation: Matt Milner presents the basics of using the Send activity to consume a service from a workflow using WCF.
Creating Custom Activities:Matt Milner presents the basics of creating custom leaf activities including how to use Dependency Properties to make your properties bindable.

Link – Synchronous call of a workflow from an activity

Jon Flanders provides an example where an activity creates and calls syncronously another workflow by using a custom service.
