Eamonn McManus’s post takes the air you through applying the MXBean framework to delineate MBeans with custom types, employing both JMX 2.0 — uncommitted in the JDK 7 platform — and the JMX version uncommitted in current JDKs.

You’ll believably have a few additional minutes on your hands while waiting for VS Express to download. Do yourself another favor and check out out the bursting changes in.NET Framework 2.0 [BradA ]. The list is pretty minuscule, weighing the breadth of the framework, but you’ll in all probability ascertain a favorite in in that respect.

My original posts on Finalization and Hosting had some artificial XXXXX markers in place of content, where that content hadn’t already been disclosed in some form.  Nowadays that the Ocular Studio 2005 Community Preview is uncommitted, I’ve moved backward to those two posts and put back the XXXXX markers with existent text.

As well, it’s manifestly been a while since my last post.  I began droping a line something this weekend, but the weather hither has been dramatic and I was obliged to move outdoors and play.  I’ll essay to have something in the next couple of weeks.

Be measured – these aren’t the same thing.

• LoadFrom() works through Fusion and can be redirected to another assembly at a dissimilar path but with that same identity if one is already loaded in the LoadFrom context.
• LoadFile() doesn’t bind through Fusion at all – the loader simply operates in front and loads just* what the caller called for. It doesn’t use either the Load or the LoadFrom context.

And so, LoadFrom() unremarkably yields you what you asked for, but not needs. LoadFile() is for those who rattling, very desire precisely what is quested. (*All the same, starting in v2, policy will be applied to both LoadFrom() and LoadFile(), so LoadFile() won’t necessarily be exactly what was requested. Also, starting in v2, if an assembly with its identity is in the GAC, the GAC copy will be used instead. Utilize ReflectionOnlyLoadFrom() to charge just what you desire - but, note that assemblies charged that way can’t be put to death.)

LoadFile() has a catch. Since it doesn’t use a obligating context, its dependencies aren’t mechanically found in its directory. If they aren’t uncommitted in the Load context, you would have to take the AssemblyResolve event in order to bind to them.

Indeed, which one should you employ? That bets on which holding context is justly for you and whether it counts that the LoadFrom context may airt the bind. Regarding the latter: Read the rest of this entry »

One of
the suggestions for a blog entry was the carryed off memory model.  This is seasonable, because we’ve barely been
retooling our overall approach to this confounding topic.  For the most part, I write on product
decisions that have already been produced and embarked.  In this note, I’m discoursing succeeding
directions.  Be
doubting.

Indeed what
is a memory model?  It’s the
abstraction that reachs the reality of today’s alien hardware comprehendible to
software developers.

The
reality of hardware is that CPUs are renaming registers, doing bad
and out-of-order execution, and geting up the world during retirement.  Memory state is cached at assorted levels
in the system (L0 thru L3 on mod X86 boxes, presumptively with more levels on
the way).  Some levels of cache are
shared between especial CPUs but not others.  For example, L0 is typically per-CPU but
a hyper-wandered CPU may partake in L0
between the coherent CPUs of a single forcible CPU.  Or an 8-way box may parted the system into two
hemispheres with cache controllers doing an elaborated coherency protocol
between these freestanding hemispheres. 
If you count hoarding effects, at some level all MP (multi-processor)
computers are NUMA (non-unvarying memory access).  But there’s enough magic proceeding that
yet a Unisys 32-way can mostly be counted as UMA by
developers.
