Architecture Chat 16 Tomorrow

Sooo....

Another architecture chat tomorrow, 11:30am at the usual spot... some possible topics for discussion.

  • Row vs Column database storage, is Column based storage important?
  • Dead Skills - What skills are on the way out / way in for Developers, DBA & Architects?
  • Castle Project RC3 will be out shortly, I'll let you know whats going on.
  • I've been watching quite a few TED presentations over the last month or so - and it leads me to wonder, what sources of Inspiration do people tap into for their own Software Creation?
  • PLINQ update - it's getting closer!
  • I thought this was interesting - a new way to detect code theft, though how many of us in NZ actually fear code theft at the moment?


Light on topics, but still there's plenty of things to fuel debate - look forward to seeing you all there.  If anyone has anything else they would like to talk about it (or raised for debate, if you can't make it along) then just leave me a comment or flick me an email.

btw - Not sure if Alex James will be making it along to this one, but if he does, it will certainly be his last before leaving NZ for the U.S of A.

Architecture Chat 15

Architecture Chat


So we had a reasonable turnout today, with 9 people.

First up for discussion was the move from Microsoft to assist with the development of Moonlight - which is making silver light an even more compelling proposition then it was before...

There was a brief talk about WPF component suites ... some of the more win forms focused of the group are looking for an easier migration path from Winforms to WPF lead by a full featured control suite...  A few of us observed that Telerik are planning to release a WPF suite of controls later on this year, and of course they already have RadControls
for Silverlight
available now.  DevExpress are also planning to release WPF controls "some time" this year, though not much information is available on just what makes up a "control suite" for WPF, considering the power provided just through the great data binding experience, simple controls like lists and the native 3D support.

Following that we had a rather rambling conversation sparked off by Alex J buying an iMac for his mum, and my desire for an entirely modal windows experience for my grandmother - or at least something that stopped windows from being able to completely occlude each other (which can cause all sorts of confusion when people associate a window "disappearing" with an action having taken place, like an email being sent).

Peter mentioned a project (which I didn't quite catch the name of) which creates a "modal" almost terminal-like experience for windows, which sounds like it could be interesting... I'm thinking perhaps I need to write myself a entirely modal shell for windows... maybe a task for a full-screen WPF app ;o)

That lead on to a conversation about undo and document change tracking, concluding in a few thoughts - we covered a random assortment of topics including MOSS 2007, WebDav and the poor uptake/usage of shadow copy some of the "thoughts" included:

  • New versions of documents shouldn't be able to overwrite old documents, period, bake in at the OS level.
  • There needs to be a change to the usability of undo/redo so that you can move backwards and forwards through change history using a slider or some kind of similar time line experience.
  • Previous text can be copied and then the slider dragged back to the "current state" to paste (With no way of interacting with the previous state, to avoid accidentally loosing the current state).


After that we branched out into talking about Load balancing, Amazon E2 i.e. the Elastic cloud, Peter hadn't heard about  Grasshopper but seemed pretty excited by the thought of converting .Net applications to run on J2EE (and as such, commodity hardware) - though Gareth mentioned it wasn't all that cheap, so you probably need to avoid having to pay a few windows server licenses to balance to books.

Data Layer Componentization and the concept of a DataServer also got a mention, a long with some discussion around the lack of an off the shelf product which solves some of the "tough" problems with implementing highly scalable and distributed data platforms ah la things like BigTable and similar map-reduce style data storage concepts.  I wonder if Pile can offer us anything in this space as well?

Last of all Alex J briefly asked about mixed-mode authentication for IIS - as it happens Ayende recently posted about this, with the gritty details of getting it to work.

And I think that's about enough from me... also don't forgot we have 2 user groups next week (Tuesday in Ellerslie, Wednesday in Auckland Central), details are below.

2007-09-05 - Architecture Chat Tomorrow

Hi All,

Another architecture chat tomorrow, 11:30am at the usual spot... some possible topics for discussion.

  • Data Layer Componentization.
  • OOXML - the "no with comments" response - anybody bother finding out what the comments were?
  • Google wiki.
  • IronPython, IronRuby... now IronLisp.
  • The so called "Digestion Phase" for technoloy.
  • Mono Olive - WF, WCF, System.Query/Linq, Xaml support (no WPF as such).


If anyone has any other ideas for discussion, just leave a comment on my blog... or just pop along tomorrow.

Architecture Chat 14

So yet another architecture chat come and gone, small turnout today, with 5 people I believe.

Had some interesting discussions none the less...

So first off a brief discussion around implementing OleDb i.e. what's involved in doing it yourself, is it worth it etc.  Alex James much prefers the idea of implementing an ADO.Net provider which is far easier, though obviously OleDB or ODBC provides a bridge to the past and to other technology platforms like php or ruby.

There are some products (such as the ones from ODBC SDK) which lets you write your own across a proprietary data source, though I'm not aware of any open source equivalent for assisting with the development of ODBC or Ole DB providers in .Net..??

After that we had a lengthy discussion about Microsoft Patterns & Practices, partly sparked by the first release of the Repository factory which seems like a bit of a non-event ... the discussion basically resolved around points such as:

  • Do they have some inbuilt desire to over-engineer these products (it definitely seems like it!)
  • Is the over-engineering perhaps sparked by a desire to appear "innovative" in the face of existing community projects, i.e. Enterprise Library logging must appear to innovate in the face of existing projects like log4net of nlogr, which already do what most developers need.
  • Are the features in the factories and libraries being driven by customer needs, or some high level vision that doesn't necessarily tie in directly with the pain developers are feeling?


I think the gut feeling of the group was that there's a definite lack of pragmatism or YAGNI in a lot of what's released from P&P which is putting people off diving any deeper, it's a shame considering the group as a whole won quite a lot of us over in the early days with the first release of the DAAB.

Moving from that we talked about the OpenXML debate... personally I thought the strong push from Microsoft came a little out of left field during Code Camp (much like the Mindscape presentation on Lightspeed ;o) - considering I hadn't heard much about it until then in the Microsoft community, and then we bashed around some thoughts, such as impacts of the standard being approved or not - and the motivations of people supporting either standard.   I think most of us aren't particularly concerned with the outcome because our projects don't normally encroach on the document generation / parsing  space - though I can certainly see it eventually having quite an impact on regional and local government for instance.

From their we talked about being entirely underwhelmed with vista sidebar gadgets, and the fact that the sand boxed environment of the gadget detracts largely from it's appeal of providing "context" related information for the application your focus is currently on at the time.  Obviously work-arounds exist, but I think we were hoping for a more formal publish-subscribe system attached to vista gadgets so information could be easily ferried between applications and vista gadgets in an unobtrusive and more formalized manor.

The Maxthon browser came up in conversation, PeterB mentioned using it a few weeks ago, and it looks like he's got at least one convert - in particular it seems that it gets around some of the annoying Internet explorer crashes on vista64, while still using the IE rendering engine etc.... I may well have to give it a go to fix Renee's Vista64 PC.

Also had a discussion around using Windows Workflow Foundation, both myself and David W are starting to delve into it for upcoming projects, and we're both finding if difficult to:

  • Find decent examples that don't target old beta's.
  • Searching only non-beta documentation.
  • Find examples which are sufficiently complex enough i.e. where's a "meaty" state engine example, rather then a toy.


Which also led onto the discussion around examples and blogging - we think products, like Windows workflow, really need some blogging community liaison that:
  • Blog's almost if not every day (small nuggets of valuable content, that will make for good search-engine fodder)
  • Releases a sample, say once a week up until the product is released, and then with follow up examples for a couple of months at least after release.
  • Maintains samples that are released on community sites as new CTP's and the all important RTM's are released, so they don't go stale over time.


Perhaps we've both overlooked some key resources - but it just seems like the content surrounding windows workflow foundation, particularly on sites like netfx3 are actively maintained until the products go final at which point, things such as samples are left targeting previous beta's and serving to confuse the community in many cases.

Next one is in 2 weeks, Thursday 6th September, we might even have a quick 15 minute screwturn plug-in development demo then... if Peter's in the mood.
