The "secret" part being that they didn't warn anybody "hey, we've
implemented a new feature to completely disable the security of your
network".

Either it does allow more people to connect, or it doesn't. Make you
mind up!
The thing about NAT is that [in the default configuration] it allows
outbound connections only. Either Teredo tunnelling changes that
invariant, or it doesn't.

The VT100 is not the only serial terminal. Anything that talks RS232 serial
is sufficient. You know, like, another Amiga, say?

It's no more disabling the security of your network than telnet or pop3 or
http is. You have to tunnel out before you can get any answers back.
Besides, it's part of IPv6. How much more do they have to warn you, other
than publishing it worldwide in RFCs?
> Either it does allow more people to connect, or it doesn't. Make you mind up!
Why don't you read up on how it works?

That is what 'surprises' me everytime. How can you design an OS where it
is possible to prevent a task switch to a taskmanager. I assume it is
because it wasn't designed but grown. Still, by now they should have
solved that, I would assume.
To Andy: I have some programs that when fed enough input will apparently
freeze the machine, if I wait 5 minutes I get it back when the process
has processed the data. So, yes it stays running. Unfortunately that 5
can also be 2 or 20, there is nothing to indicate what will happen. In
defence of Bill, my Ubuntu version just crashes. It does not freeze the
machine, but it also gets nothing done.
BTW this is when reading a 1-2 million faces text file in into Blender.
And when going into edit mode after that and...
(but Maya can not even handle halve as much).

The only thing I use Blender for is to build meshes. That works great
for me. My alternative would be something like Maya, but that has an
even more complicated interface (from a GUI point of view).
In the next few weeks I will use it too to make meshes, so I'll keep you
posted on the progress.

I have used both the pre 2.5 versions and the post 2.5 versions (that is
really completely redesigned) and although I know this common complaint
I cannot confirm it.

It's really not too hard. Modern desktop OSes suck at scheduling disk I/O,
so if you're locked up because of disk I/O and you launch a new program,
you're going to be locked up.
Sit down at a Linux machine with 16G of RAM. Create a directory with
1,000,000 one-block files, then type "sync", then type "rm -r xyz;sync" and
watch Linux "lock up" for several minutes as anything that wants to touch
the disk waits for the sync to finish.
Same thing can happen if you have a whole ton of data paged out when you
terminate the application, as AFAICT both Windows and Linux will happily
page everything back in as it terminates the job.

Disk I/O sucks in every modern desktop OS. Android also "locks up" on
occastion for several seconds at a time, as some random program launches a
check for something online when you're in the middle of typing something,
for example.
Contrast with CP/V, a mainframe OS from the late 1960s, that ran on a
computer with *maybe* a 500KHz CPU running out of 256K of magnetic core that
happily supported 40 or 50 users before you started to notice any slow-down.
How? They had something like 30 or 40 different priority bumps depending on
what you were waiting for and what woke you up. Waking up from waiting for
free memory (i.e., someone else's page-out completing) vs waking up from
waiting for pages to page in vs waking up from waiting for a directory entry
to come from disk vs waking up when disk data has arrived vs etc all had
different priority bumps, including on whether you're in core, out of core,
finished your quantum last time, waited before your min-quantum expired last
time, etc etc etc.

Oh, OK.
So what can you actually do with a "kernel debugger", anyway? Just look
around the machine's memory or something?

OK. So how is my statement that "you cannot log in to it from outside
the building" invalidated then?
