So, you’re hosted in a single zone, and if you’re in US-East presumably went down last night. Stop it. AWS has seven regions across the world, three of which are in the US. Each region is split in up to five avaliabilty zones. You need to use more than just mulitple zones if you want to stay up during one of these outages. Cross region is the answer. Continental redundancy is your friend.

So you want to do some DirectX immediate mode rendering in your C#/XAML app ? Let me walk you through how to do that using the SharpDx library
Combining XAML and DirectX is an excellent msdn article that talks about what is possible with DirectX and XAML. Unfortunately there are no examples and what information there is available is targeting the XAML/C++ world. I wanted to do this for us managed programmers!
SharpDx is a very thin library that exposes the DirectX api’s for use in C# WinRT apps Smile . It exposes the DirectX API’s nearly 1-to-1 with no higher level abstraction (like what XNA is). We will use this library to render DirectX content in our XAML/C# apps via the new controls mentioned in the above article (SurfaceImageHost & SwapChainBackgroundPanel)
Alexandre Mutel is the brilliant guy who owns SharpDx, he’s done a lot of the hard work for us BUT help is very scarce with getting these bits working on your Win8 development environment.
I’ll spend this post walking you through how to get this all setup. It’s a simple post that will set the foundation for some awesome UI/UX rich future posts!

Umbraco 5.2 Release.
Along with the realease of Umbraco 5.2 comes the announcement that Umbraco 5 development is being discontinued. Evidently, the plan is to integrate all the nice MVC features of Umbraco 5 into Umbraco 4.
Considering I have spent the last few months learning MVC and getting some Umbraco 5 sites running on Azure, I am not amused.
EDIT: Blog post about this that goes into more details.

Oh! thats really not a fact of amusement I was also interested to umbraco5 as i learned MVC...

I'm hoping the 5 features will make it into the 4 version sooner rather than later, but I don't have the time right now to watch the hour long video that presumably goes into more detail. Though if you are curious, the video is linked to from the 5.2 release page.

Certainly have to agree with that. Working with WPF and Silverlight. Some great technology, but Microsoft has not done much with technology in years. HTML5 is just another patch to technology that was intended to display simple text in a small browser window (displays were not that big back then). Wish we could move on.

Word processors such as Microsoft Word are said to be WYSIWYG: what you see is what you get. In a sense that’s true, but in another sense markup languages such as HTML or LaTeX are really WYSIWYG. Text files are simpler because there are no mysterious forces at work.

TL;DR: for text files, notepad is WYSIWIG. For a completely useless definition of WYSIWIG.
I might be monday-morning-dense, but what'st the point?

For executables, blue screen of death is WYSIWIG. Yes, there is no point.

I think the point was that proprietary wysiwyg editors like Word interject an intermediary layer to do their magic that work fine for most users... until they don't. I've had Word docs corrupted or choke on some formatting and there's no easy way to figure out how or why it's that way. And how to fix it.
That's well and fine for most people most of the time.
Text files work better (in some ways) if you know what you're doing (HTML or Markdown or LaTeX or...) and the "what you see" is as important as the "what you get". Ever seen the HTML output from Word? Can you imagine what's happening inside the DOC/DOCX file? Yikes.
Back in the day we used FrameMaker for publishing and even though we did most work in the wysiwyg editor, the text-based file format was a blessing for troubleshooting problems.
There's also the concept - which I subscribe to - that many features wysiwyg editors give us are extraneous to the content and complicate more than they help. Plain text, Markdown, simple HTML markup make for more portable files, more focus on the content and, these days, can be easily and quickly parsed for fancier presentation formats (web pages, HTML/CSS slides, etc.) when necessary.

OK, that starts to make some sense.

Yes, and I've been around when WYSIWIG became a distinguishing feature.
For me, at the heart of WYSIWIG, is the user interacting with the result itself: e.g. instead of a list of picture names and subtitles and format instructions, they are interacting with a photo album. It *removes* the user interface from perception: instead of clicking a button that makes the text bigger, they make the text bigger.
Of course, all abstractions are leaky (or, as D.A. said it, "The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong it usually turns out to be impossible to get at or repair"). So yes, being able to delve down can be a life saver.
In the end, tghe real life analogy is also limiting - which isn't always bad, humans like handrails. It might help focusing on the really important stuff, like finding a funny title for the 57th picture of Jon and Kiran pouting.

It also occurs to me that we see the circle complete itself again with tools like jsFiddle[^] or Multimarkdown Composer[^], which blur the line between code, markup and WYSIWYG.
Or even IDEs that autocomplete your code right down to the semicolon.
Quote: Yes, and I've been around when WYSIWIG became a distinguishing feature.
Indeed, I recall doing my writing and markup in WordPerfect and handing off to the desktop publishers for formatting. Man, I dreamed of better WYSIWYG tools. And they arrived, after a fashion. But all the WYSIWYG features in the world don't make page layout in Word any less soul-destroying. And now I find myself back in a (slightly more sophisticated) text editor, handing off to publishing tools only when necessary.
What's old is new again.

Though C has been around for decades, it's still consistently ranked at the top of any list of programming languages used and studied today. I recently spoke with David Griffiths, coauthor of Head First C, about the reasons for C's continued (even increased) popularity. Respect the classics, man!

On Saturday, at midnight Greenwich Mean Time, as June turned into July, the Earth’s official time keepers held their clocks back by a single second in order to keep them in sync with the planet’s daily rotation, and according to reports from across the web, some of the net’s fundamental software platforms — including the Linux operating system and the Java application platform — were unable to cope with the extra second. What did you do with your extra second?

I wrote Tumblr, Instapaper, and Second Crack in PHP. I continue to use it because I know it extremely well, it’s very easy to use and deploy, and it’s nearly maintenance-free on servers. When you’re a programmer forced to also be your own sysadmin, that’s very attractive. But I hate it. It’s limited, often clunky, outdated, and deeply flawed. When comfort and speed get in the way of becoming a better developer.

What’s keeping us using desktops and even notebook, then, are corporate buying policies, hardware replacement cycles, and inertia. How long before the PC as we knew it is dead? About five years I reckon, or 1.5 PC hardware replacement cycles. Nearly all of us are on our next-to-last PC. Mobile devices are moving on down the road.

I don't know too many iOS and Android developers who develop code using iPads and Android tablets. Trust me, the laptop/desktop isn't going to go away anytime soon.

Perhaps you think that Twitter today is a really cool and powerful company. Well, it is. But that doesn’t mean that it couldn’t have been much, much more. I believe an API-centric Twitter could have enabled an ecosystem far more powerful than what Facebook is today. APIs versus advertising: only one can win?

When the iPad first appeared on the market, publishers immediately saw its potential as a media-consumption device. Indeed they were right: iPad (and tablet) users are more likely to buy content than smartphone users. What they were not right about though was that native apps were the right vehicle to break into this market. A number of high-profile publishers have been recently abandoning native apps in favour of the mobile web. Learning lessions from 500 years of non-proprietary print.

In artificial systems it seems we need a new and broader definition of self-awareness - but what that definition is remains an open question. Defining artificial self-awareness as self-recognition assumes a very high level of cognition, equivalent to sentience perhaps. But we have no idea how to build sentient systems, which suggests we should not set the bar so high. And lower levels of self-awareness may be hugely useful and interesting - as well as more achievable in the near-term. Why are we fighting to save the humans? They're a primitive and violent race.
