attempting to return a multiple group by object
Was hoping for some help with Nested group by in linq where I am trying to
go down three levels.
Basically the path would go down Business to BusUnit to Level1
So under Business there are various BusUnits and under BusUnits there are
various level1 values
I want to return this as a Json object.
As I have it at the moment I got down to BusUnits
as follow
var queryNestedData = (from r in DataItems
group r by r.Business into businesses
from businessUnits in
(from r in businesses
group r by r.Businessunit)
group businessUnits by businesses.Key).Select(tg =>
new
{
Business = tg.Key,
BusinessUnits = tg.Select(tv => new {
BusinessUnit = tv.Key })
});
How could I get to Level1 so as to return the values as well?

How to get a new gps coordinate at a known distance that lies between a known start and end gps coordinate?
How to get a new gps coordinate at a known distance that lies between a
known start and end gps coordinate?
I am working on google maps api + python code, And i'm kinda stuck with a
doubt. I basically have 2 gps co-ordinates, start and end point, and i am
able to calculate the shortest distance between them using the ideas i got
from stackoverflow. for example lets say the distance between (x1,y1) &
(x2,-y2) is 100 meters. Now the next task is to get a list of coordinates
which is lying on the same path between start & end point 10 metres
apart(which basically would be 9 more coordinates coz the 10th will be the
end point which i already know). I can apply ratio calculation and get a
(x,y) out but keeping the earth's spherical structure in mind is there any
other algorithm, theorem, package or solution you'd recommend? I'd
appreciate any thoughts that you'd like to share. thanks.
also will the solution mentioned in this link work? Adding distance to a
GPS coordinate

how to send sms ( text message ) from oracle database 10g / forms 6i
how to send sms ( text message ) from oracle database 10g / forms 6i
I want to send sms from oracle 10g, there is a lot of information for this
on web and I found the following are required:
sms gate way ( ozekisms.com )
GSM modem
SIM card from a mobile company
Now I want to confirm from the community before purchase a sms gateway
software and GSM modem. Is there any free sms gateway? Which GSM modem and
sms gateway software is more reliable, easy to use and cheap?

Trying to step through BackgroundWorker code in debug but program ends unexpectedly
Trying to step through BackgroundWorker code in debug but program ends
unexpectedly
Here is the code I am working with:
try
{
mainWorker = new BackgroundWorker();
mainWorker.DoWork += (sender, e) =>
{
try
{
//stuff I want to have happen in the background
//I want to step through the lines in this try block
}
catch
{
//exception not being caught
}
};
mainWorker.RunWorkerCompleted += (sender, e) =>
{
//code to let user know that the background work is done
};
mainWorker.RunWorkerAsync();
mainWorker.Dispose();
}
catch
{
//exception not being caught
}
I do not see any exceptions being thrown. I have a breakpoint set inside
the try block in DoWork. Sometimes it hits the breakpoint, but after
stepping through a certain number of lines the program ends. It doesn't
always end on the same line of code. Sometimes it doesn't hit the
breakpoint at all.
The code steps through normally if I eliminate the background worker.
I haven't implemented background workers before and I'm trying to figure
out what I'm missing that's preventing me from stepping through my code.

routing problems assigning a whole IPv6 /64 to one host
routing problems assigning a whole IPv6 /64 to one host
I posted this question before, but it got deleted for some reason.
I've recently boughy a dedicated server, and I've been assigned a /64
subnet. How do I route all of the IPs without manually adding them all
with ifconfig? Thanks. I tried with the command specified in another
serverfault, 2001:41d0:1:5976::/64 being my subnet:
ip route add local 2001:41d0:1:5976::/64 dev lo
Kernel is 3.2, distro is Debian. I need to do this to flexibly use any
IPv6 in my subnet.
Now though, I can't ping IPs:
# ping6 2001:41d0:1:5976::3
PING 2001:41d0:1:5976::3(2001:41d0:1:5976::3) 56 data bytes
