I have recently built my own plugin for Glimpse to see all my Couchbase traffic, and would love to see statistics on what is going on in Autofac. Is there any work being done on an Autofac plugin for Glimpse? All I can find is the one from three years ago, but I don't think it shows a whole lot of detail.
Ideally what I would be looking for would be a full plugin that can do timings also, to measure the performance of Autofac using Glimpse and work out how much time is taken to resolve instances to isolate potential performance bottlenecks.
Has anyone done something like this? If not, does Autofac have hooks we could hook into to capture that stuff and log it?
I'm not aware of anyone who is currently creating a Glimpse extension for Autofac.
As you mentioned, there is an extension out there now, but it might not be as detailed as you'd like.
All that said, it seems like Autofac's Activation Events would make it pretty simple to create a new Glimpse extension to expose some of the data that you're after.
For timings, if you are using an IServiceLocator in MVC, you could also create a GlimpseServiceLocator which uses a Stopwatch to get timing information.

I'm using ScalaJS with Play. Many of the models I'd like to use on both JS and JVM platforms involve dates and times. Given the lack of a cross-platform date/time library, how are people approaching this?
Things I know about:
scalajs-java-time project (https://github.com/scala-js/scala-js-java-time) to port JDK8's java.time api to Scala.js. Unfortunately, it's far from complete and judging by the commit logs, seems to have stalled.
https://github.com/mdedetrich/soda-time is a port of JodaTime to Scala/Scala.js. But it's not ready for production use.
An old post at https://groups.google.com/forum/#!topic/scala-js/6JoJ7x-VxLA suggests storing milliseconds in shared code and then doing implicit conversions on each platform to either js.Date or JodaTime. But we really need a common interface, which this doesn't give.
Li Haoyi's excellent "Hands-on Scala.js" has a simple cross-platform library (http://www.lihaoyi.com/hands-on-scala-js/#ASimpleCross-BuiltLibrary) that could, in theory, be extended to come up with an API in /shared that delegates to JodaTime on the jvm and Momento on js -- but that sounds like a lot of work.
(added later) https://github.com/soc/scala-java-time is based on an implementation of java-time that was contributed to OpenJDK. The README claims that most stuff is working. Right now, this looks like the most promising approach for my needs.
Any advice from those who have gone before me? Right now the fourth options seems like my best bet (with the API limited to stuff I actually use). I'm hoping for something better.
I was in the same boat as you, and the best solution I came up with was cquiroz's scala-java-time library. From reading the comments to your question above, it appears you landed at the same place eventually!
I came here from a google search, and given how much better this solution is than the alternatives you mentions above, let's consider marking this question as resolved for future visitors.
I am capable with PHP, HTML, CSS, JavaScript and SQL, and not bad with Drupal. Very recently, I acquired a customer that wants me to do some SocialEngine 4.xxx customization. My customer is aware that I have no experience with SocialEngine, but am capable with the underlying technologies (I gave him a lower hourly rate because of this too.)
I'm not seeing very much online that is geared towards someone like me. Where can I read about modifying SocialEngine that assumes very little knowledge about SocialEngine, but a competency at programming?
For example, I spent a few hours today trying to figure out how to conditionally display a block based on a Membership Level. It appears there is no way to do this using the GUI. No problem, I found some code that seemed like I could get it to work that would grab the user's membership level. However, where do I put this? Honestly, I'd like to have this at the block-level. SocialEngine doesn't seem to allow me to place arbitrary PHP code into a block, and even if it did, would that be the "SocialEngine" way of doing this? Should all custom logic like this be a module in SocialEngine, that attaches to events using hooks?
Thank you very much for looking at my question,

I've written a blog about accessing data through models, creating widgets and modules. You can find out about the general structure of Social Engine at http://garbtech.co.uk / http://socialenginetutorials.co.uk (both same blog)
Unfortunately, there are no books or official documentation on SocialEngine PHP API. Your only choice is to check out various (incomplete) guides over the Internet or study their source code and figure things out by yourself.
We currently use FogBugz at work, and I'm using the URLTrigger plugin to call out to a CGI script every time a case is changed. I'm trying to figure out how to do something similar with Trac; does anyone know if this is possible? I can't find any plugins or discussion on it.
t-h.o is the first address to seek for Trac plugins. Because Trac is actively encouraging plugin development by it's sophisticated Component Architecture since early days, you'll find a lot of code. And since Trac core developers have been involved, this is often quite good code quality too. Stuff you'll read to get an idea on how things are supposed to work.
Maybe you'll want to start with current official wiki docs to dive into Plugin Development for Trac and change over to trac-hacks.org afterwards.
Regarding your declared development goal especially look at trac.ticket.api.ITicketChangeListener - an extension point interface for components that require notification on when tickets are created, modified, or deleted. Sounds like this is just what you want.
You'll need to (rough list of requirements)
create a class based on trac.core.Component that
implements (ITicketChangeListener)
provide modules exactly as required by the interface definition
If you need more details, I'd recommend to look at the DefaultCcPlugin source. There are many more plugins implementing the ITicketChangeListener interface, but this is a rather small plugin, that'll just show you the available methods and not distract with too much functionality around them.
Add information to your question as you progress, or Comment here as required. I'll try to guide you further on to the best of my own knowledge.
I am writing my own custom persistence instance store for WF4, based on the XmlWorkflowInstanceStore found in the .NET 4 WF and WCF samples. This sample is quite simplistic and the xml is produces is quite verbose. I have issues with how some of the objects are serialized.
I have tried using Red Gate Reflector to understand the Sql implementation used, but it is quite complex and difficult to learn from. The MS documentation for this is rather limited - often giving one sentence descriptions for complex methods.
Please could you point me at other examples of WF4 persistence (or proper documentation) around on the web that are not copy and paste versions of XmlWorkflowInstanceStore? Maybe someone else on StackOverflow has written their own?
You are completely correct that the docs are very much lacking here and the sample is of very limited use. I have started work on a custom instance store using the entity framework but, much like you discovered, found it slow going and am nowhere near anything I could use myself, let alone release onto CodePlex.
I am not aware of any blog posts or other information that help solve this.
You've probably seen this already, but I've found the code quite easy to understand: http://xhinker.com/post/WF4Xml-persistence-store.aspx
Ron Jacobs wrote an in memory persistence store for WF unit testing. Check out http://wf.codeplex.com/releases/view/73842
How easy it's to come up with a drag and drop web-based interface that'll provide me features to wire objects together, setup configurations nicely in a modal window for each object? I'm looking for links that've any similar kind of interface, or articles on this. also, i'm looking for your technology/language suggestions.
Another way I'm thinking - as a desktop appln + browser dependent addon..
Is it good to create such an user-interface using XUL, which can be deployed as an addon on Firefox/as a stand-alone application in Windows? Are there any other similar things/technologies which can provide a basic framework for us to build on it further?
Why do I need this, finally?
..for building simple Workflows, for defining process flows, that can provide me some auto-generated xml content which I can use for further processing.
Thanks!
I'm quite interested in this, too.
I've flirted with HTML5's DragDrop implementation - Quirksmode has Bad Things to say about that, so then I thought "Perhaps a JavaScript library can help me" - haven't checked out jquery for this yet, but I have checked out YUI's DragDrop, DragDropManager and DataSource, and its looking hopeful (consistent, reliable).
I tried things like adding an iframe on the fly to any document, to provide this kind of functionality without needing to add dependencies to the page given the iframe - mixed results, but in my case I was trying to cater for x-domain access, which proved difficult.
So I'd say JavaScript could be a winner - if designed poorly it could be difficult to manage resources though, if you want to potentially DragDrop/edit/config any element in a document - so watch out for that.
If you're keen and able, Adobe AIR apps also look promising - but I can't help with any more info on that, other than they're Desktop Apps with great flexibility.
I'ma going to keep an eye on your Question, I look forward to any other Answers/comments!
EDIT: I forgot to mention Flex (aka Flash Builder 4, latest version) is quite easy to create stuff like this, though I've had exposure to Flash for a while. It comes with the standard Adobe caveats; price, libraries, support.
