XBox, History, and Houses

Expend a prominent chunk of today runing 6 player Halo over at a friend’s house. That game is so awful. We speak a small bit about the idea of video games being a spectator sport. Not a newfangled or refreshing concept. In fact there are people aiming paid off to run video games today. There are, of course, professional testers and act testers, but and so there are likewise those people given to act massively multiplayer games (like Everquest and Ashron’s Call). I have a friend that was yielded free online time with AC if he agreed to tutor people online. The interesting thing was that there was a team meeting for a big division at work where there were likely 100 spectators watching over a Halo tournament. How long until there is an arena?

Terminated the weasel , but guns is studying longer. A very interesting thing in guns is the idea of history in the prominent. I think taking the Foundation books (good, some of them) and in that (if memory serves well) Asimov has this concept of next history. That you can fundamentally prognosticate the behavior of the human species over a farsighted enough time. In the book they double-dyed this technique and can in truth prognosticate the future. In guns Diamond talks about history expending these unsubtle strokes of time. He utters approximately “little” time crosss being 1,000 years. Distances are measured in the time it views as ideas and people to inhabit an area, avering that the Americas were populated in a poor 8,000 years from the time the first people came across the consecutive.

Roleplaying Multiple Cooccurring Sounds in WPF

WPF’s MediaElement makes believe bare media playback pretty square, but moving beyond the mere scenarios can sometimes bring up surprising challenges. For example, I late saw someone triped up up by the MediaElement when assaying to run several sounds at the same time.

As you’ll pick up, one solution would have been to expend MediaPlayer alternatively of MediaElement. The difference between these WPF classes is fairly square. MediaPlayer is the class that recognizes how to run media files – both video and audio. MediaElement is a wrapper around MediaPlayer that plies a uncomplicated way to tie it into a ocular tree (i.e. a user interface), which in turn gets us addict it into things like the animation system or event triggers.

(Remark: do not be misled by the class name. Although WPF and Windows Media Player depend upon the same infrastructure for media decrypting, the MediaPlayer class is not a wrapper around the Windows Media Player control. While they partake codecs, the path by which deciphered video twigs the screen in WPF is significantly unlike from Windows Media Player.)

How would that have you into trouble when utilizing MediaElement? If it’s a wrapper around MediaPlayer, certainly you could utilise a MediaElement any place a MediaPlayer would lick? In fact it’s not e’er that uncomplicated. To run across why, we’ll start with a elementary example.

Windows XP and the importance of listening to customers

On June 30, Microsoft will quit Windows XP in an effort to coerce all PC users onto Windows Vista.  As this date catchs closer and closer, they have mulishly asserted that they will not exchange their plans.

Last week, Microsoft CEO Steve Ballmer blinked , but in a rather perplexing way:

• The sensitive part:  Ballmer laid claim that they might reconsider their decision if that’s what customers desired.

• The discombobulating part:  Ballmer seemed to be completely unknowledgeable of the multitudes of people in public begging for XP to catch a stay of execution.

Scarce desire kind of customer feedback would Ballmer be capable to try?

It’s genuinely not that difficult to feel overpowering evidence of magnanimous numbers of people who desire to carry on utilizing XP.  A uncomplicated Google search for the string “make unnecessary windows XP ” ensues in over 200 thousand hits.

Oh yea, I blanked out — Steve plausibly doesn’t use Google.  Perhaps the problem is that he simply can’t discover any XP fans on the Internets? 

Or possibly Ballmer is complying the nowadays stylish trend of calculating an Internet person as merely 3/5 of a existent person?

• Sure as shooting, Ron Paul has lots of fanatic supporters, but they’re by and large simply people on the Internet, and they don’t really count.

• Sure, Barack Obama has raised truckloads of money, but he mostly gets it from people on the Internet, and they don’t really count.
• Sure, over 170 thousand people have signed the Save Windows XP petition , but those people are on the Internet, so they don’t really count.

Load(AssemblyName)

Calling off Load(AssemblyName) is not of necessity the same as calling Load(String). If the AssemblyName.CodeBase is not determined, and then they do do the same thing. Thusly, if you’ve plant the AssemblyName.Name, CultureInfo, public key token / public key and/or Version properties, it would be the same as if you had stipulated those properties in a String (as a display name ) and extended that to Load(String).

If the CodeBase is planted, but the Name is not, still, and then it’s the same as phoning Assembly.LoadFrom() on that CodeBase.

When both the CodeBase and the Name are planted, and so the bind is tried with all the imparted holding information except the CodeBase (thusly, once more, simply like ringing Load(String)). If that wins, we’re performed. But, if that betraies, and then the bind is essayed once again with exactly the CodeBase (precisely like LoadFrom()). If it betraies once more, and so, of course, the hale bind betraies. But, if it brings home the bacon, and so we control that the tiing up properties in the AssemblyName jibe the noticed assembly. If they don”t match, a FileLoadException will be thrown for hresult FUSION_E_REF_DEF_MISMATCH.

So, setting both the CodeBase and the Name is useful for when you want to both load an assembly at a given path into the LoadFrom context, and verify that it has the public key token, etc. that you expect. Of course, as described above (and imputable to binding context rules ), keep in mind that precisely because you phone Load(AssemblyName) with a CodeBase, it does not think that it will be loaded from that path.

Should “Membership Stores” Be Permitted in Redmond’s Constructing Park Zone?

In coordination with Taylor Development, which among other things haves an unexploited 60 acre parcel of land that is districted Fabricating Park (MP) along Union Hill road in Southeastern Redmond (realise Redmond districting map hither  and Live.com Map here ), City Staff has delivered the Redmond Designing Commission , of which I am a presiding member, with a proposal to expatiate the list of allowed uses in Redmond’s Fabricating Park (MP) zone to let in “Sweeping/Retail Membership” stores. In other words, they aim to enable folks like Mr. Paul Taylor with the flexibility to establish a Costco or Sam’s Club-type store out by the UPS distribution center, east of Target and Mervyns, in SE Redmond. To conciliate this, Redmond City Staff has advised that we permit such uses in all the MP zone in SE Redmond. throughout the City of Redmond.

Correction, 5/8/2007: I have been informed that the suggested regulative ammendments to allowed uses in the MP zone would confine sweeping-retail stores to the MP area in Southeastern Redmond just.

What do you recall? If you subsist in or near Redmond and specially if you transpose through or exist in or most to Southeasterly Redmond near a Fabricating Park Zone hither (to/from Redmond via Avondale Road, Redmond-Fall City Road, Willows Road, or other), I’d care to find out what you entertain this proposal. I am one of the Planning Commissioners who will presently vote on whether or not (and why) the City Council should sanction this poped the question change. Your opinion matters to me. But more significantly, your opinion matters to your fellow residents and elected officials. As such, I advance you to remark, on public record, by netmailing your thoughts to Sarah Stiteler , with the City of Redmond. I’m trusted that Sarah can as well allow for you with the replete Technological Committee Report, which I can’t find on the City Web Site (argh!), that outlines why City Staff conceives this poped the question change to be executable, appropriate, and effectual.

TransparentProxy

One of the repeating requests for a blog is related to TransparentProxy, RealProxy, Contexts, Interception, etc.  As common, I’m typewriting this where I put on’t have access to our bodied network and the sources, so some details might be a little off.  (When will my dentist allow for spare wireless to his customers?)  And, as common, none of this is leading to help oneself you in training applications.  In fact, I tabled writing about this topic – despite all the requests – because it appears so vague.  But if you are struggling through the Rotor source base, it might excuse some of the code that you discover.  I suppose ‘might’ because I’ve ne’er in reality dealt the Rotor sources.  I’m barely relying on the fact that they are a pretty close of a cleaned snapshot of our desktop CLR sources.  In any event…

 

Ordinarily, a reference to a carryed off object is scarcely that: a aboriginal memory pointer.  This is covered accurately to the GC thence that we can go after reachability and so we can update that pointer if the object is relocated during a compaction.  But in the case of an object that derives from MarshalByRefObject (MBRO), it’s potential that the object instance is in reality distant.  If this is the case, a proxy remains firm in for the server instance.
