I understand the sentiment here, but I think there are a couple of 
misconceptions.

1) it is not required that you enter your address at all
2) if you choose to enter it, you may be as non-specific as you like.  
For instance, you can enter "Sheffield, UK" as your address, and the pin 
should go to the "center of town".  Alternatively, you can enter a 
latitude/longitude location, if you want to put the pin somewhere else.

Hello Ian,
I wonder what treasures you are sitting upon on your piece of property in 
Suffolk. As for my part, I'm very grateful to Alex and others to have made 
this view of the world transparent to all users. If someone wants to spot 
me it costs him only a line in Telefonbuch.de and Maps and Route, anyway, 
and he gets the address and even a satellite photo of my house and garden. 
Can't get out of it today.

More: I joined this mail group beause I want to profit from the knowledge 
of others and to contribute when I can help, so we all can learn mutually 
from each other. I would be glad if there were someone near my property in 
Bavaria so we could excange directly and visit each others' places and 
workshops (and exchange rare or surplus parts, as has happened before). I 
can't see the use of anonymity here.

Best regards
Peter Blodow

Hi Peter,
No use looking for me in Suffolk - I'm in Sheffield, South 
Yorkshire...... the one that's famous for the world's best 
cutlery, knives and steel !!  You would also have to look 
quite hard to find any real treasures although my home made 
and designed desktop miller and lathe combination gives me a 
lot of pleasure in the odd minutes I can take away from my, 
almost constant, grandparenting duties....
I don't think I have ever been to Bavaria although I love 
Austria - I must have a browse around Bavaria on Google Earth..

Best wishes,

Ian

I hacked the map some more, and now the markers should only be visible to 
registered users.
So if you're not signed in, you can't see any data (except the data we 
publish, like the EMC Fest location for this year).
We can also add other markers (NAMES maybe? or any other emc events..).
If you're still uncomfortable with adding your address, the City name should 
be more than enough.

Regards,
Alex

As a new guy,  I start my study of the HAL literature.
Noting my questions,  I thought to burden the group in a feeble jesture of
participation ;-)

this example quizzes me:

To connect a signal to a pin we use the net command.
halcmd: net X_vel <= siggen.0.cosine
To see the effect of the net command, we show the signals again:
halcmd: show sigignals:
Type Value Name float 0.00000e+00 X_vel <== siggen.0.cosine
When a signal is connected to one or more pins, the show command lists the
pins immediately following the signal name. The “arrow” shows the
direction of data flow - in this case, data flows
from pin siggen.0.cosine to signal X_vel. Now let’s connect the X_vel to
the velocity input of a step pulse generator:
halcmd: net X_vel => freqgen.0.velocity
We can also connect up the Y axis signal Y_vel. It is intended to run from
the sine output of the signal generator to the input of the second step
pulse generator. The following command accomplishes
in one line what two net commands accomplished for X_vel:
halcmd: net Y_vel siggen.0.sine => freqgen.1.velocity [end of quote]

Why no arrow  between Y_vel and siggen?

Also,  the machine reply <== uses two =,  is that significant?

Perhaps additional study will explain it to me,  but reading to this point
 has me wondering.

TIA

I recently learned this myself...

>From the HAL manual section 1.1.4 net:
"The direction indicator "<= and =>" is only to make it easier to read for
humans and is not used by net."

HAL knows what can accept input and what can accept output and does what it
needs to do automatically and will error if you try to make it do something
it can't.

I think the hal syntax is a pretty neat way to wire up a directed
acyclic graph.
I've played with graph programming for a very long time and here is
another syntax that, one day, we may want to think about:

value= function( input1, input2, ..., inputN )
more_output = another_function( value, 5 )

repeat... etc

What is nice about the syntax is that it looks like regular functional
programming and yet it actually wires a graph at the same time.
Everything to the right of '=' is an rvalue or input pin; everything to
the left is an lvalue or output pin.

Another idea is that anything that outputs multiple pins could be
dereferenced using matrix or pointer notation. E.g.
Output[0] or output.0

Just ideas for thought.
- Mike

Perhaps the intent of my remarks were misunderstood, or
at least buried by others concerns.

My point was that a casual visitor to the web site would
have no idea that the map or forums even existed.

For me at least, it is not possible to see any of the above
without registering and logging into the system.

Alex,

Thank you for your work. This is an awesome feature!

Sincerely,

Patrice
Portland, OR

Hi Steve,

I got them, but there is also the concearn other people are having (having 
public viewable address data).
I understand some have no problems with having their address up, some do.
I chose (for now, and it's up for debate) to have the users beeing visible 
only to registered visitors.

On the other hand, people concearned about revealing info about themselves 
are not forced to enter any data they don't like.
Entering only the city, area, country should be enough to put a pin on the 
map.

Regards,
Alex

This seems like the obvious solution to me.  If anyone wished to visit, they
would still have to call or email, to make sure the person was home - so
there's no real reason to put exact addresses.

If privacy still bugs people, take a screenshot of the populated map. Resize
it to 25% or smaller, and put it on the homepage so that unregistered people
know about it.  If the image is resized, there's no way anyone could get a
very accurate location from it.
