Strange but True...weird allocation problem with .NET?

From Patrick Hynds (repro in link above):

If you try to allocate an array with a size range between 0x027fefbd and 0x027fffec, the framework throws exceptions. This range corresponds to memory block of little under 40MB. But if allocate a buffer smaller than or larger than this range, then every thing is fine. So the following call will fail.

Byte[] test = new Byte[0x027ffc22];

It looks like there are different algorithms for big memory block allocation. Is there something special about this range?  Anyone?  Note: I'm running this on a box with 512megs.  Does this behave different on a box with more or less?

UPDATE: Until someone gives an good explaination, Dejan has added this to the .NET Bugs Registry...

It's beginning...

Very soon my friends.  I'm on a MiniMed 508 and have been for 3+ years (spent the first 7 using shots up to 6 times a day).  I'm digging this new Paradigm 512...How do I get one???  It's such a great (and obvious) idea, it just might work!  It's not implanted, it's not automatic, but it's better that what we have now.  The real question is, how accurate can its suggestions be? 

It's quite a clever thing.  The Blood Glucose Meter "talks" to the pump wirelessly and informs it of your current BG.  Hopefully this happen totally automatically, it would be a shame if you had to "tell" the meter with some extra step/button press.

The meter looks a lot like an upside-down Ultra.  I'm not too excited about switching away from my beloved UltraSmart, but for wireless, I think I can be convinced. :)

Be sure to take a look at the Paradigm's Users Guide.  Often User's Guides can tell you more than the polished press sites will.

From my blog to God's Ear...

A few thoughts that we open the second day of the XmlDevCon or "SellsConIV." 

  • I wonder how many people here seriously debated wearing the conference T-Shirt we were given on Day 1...I thought about wearing it just because it was clean!
  • Seems to me that in some way Necho is being created as a "routing" protocol...to route around Dave Winer.  Note that many years ago the real Necho was an Egyptian Lord whose goal was to reach Haran to assist the Assyrians who were under seige by Nebuchadnezzar.  Are we under seige by a Babylonian King?
  • Looks like Sam Ruby can't make it to Portland.  That's a damn shame, he will be missed.  Consequently the Amazon.com fellow's VERY interesting session has been extended to include more technical details.  An unfortunate tradeoff, but the nice thing about a SellsCon is that any speaker can take their talk as deep as you'd like.

These are great...I had to collect them in one place for my own personal posterity.  Tony is a very cool guy.

  • (responding to a situation that Tony thought was unlikely to occur): "...there's also a finite and infinitesimal chance that due to quantum tunneling we could all fall straight through this floor."
  • "Does a one-legged duck swim in circles?" (as another way to say "Is the sky blue?")
  • "Drinking is like quantum theory - you can either know how many drinks you had, or what you drank, but not both."
  • To Mike Kass (and countless others in the past, I'm sure): "Mike, everyone has something to bring to this meeting--you should bring silence
  • "A gunshot wound is nature's way of telling you that your camouflage isnÂ’t working”

Keith Ballinger is up now, talking about a topic I dig, WSE - Web Services Enhancements.  He's also wearing Chris Sell's belt.
