Duga-1 and Duga-2 (Russian: Дуга - "duga" means "arc") were Soviet over-the-horizon radar (OTH) systems. They were developed for the Soviet ABM early-warning network. Both of these radar systems were aimed east and were fairly high power. They were predecessors of the Duga-3 or "Steel Yard" OTH system, which operated from 1976 to 1989.
Duga-1 was the first experimental system. It was built outside Mykolaiv in the Ukraine, and successfully detected rocket launches from Baikonur Cosmodrome, about 2,500 kilometers away.
The second prototype, Duga-2, was built on the same site. Duga-2 is able to track...

Thank you for moderating us! And thanks to all the moderators that we had before you.
I bet we'll see at least some of you as moderators again soon!
A little background - these are classes I've written on top of an Entity Framework model that represents tables on Sql Server with the following names:
Dictionary.Databases, Dictionary.Schemas, Dictionary.Tables, Dictionary.Columns
SysData.Databases, SysData.Schemas, SysData.Tables, ...27
I wrote the following simple function in JavaScript that finds the sum of all the multiples of 3 or 5 below a value, given from a text-box
I have used "n/2(a1+an) (sum of arithmetic sequence )"
function sum_of_all_mul_3_5(){
var value=parseInt(document.getElementById("input").value);

Big thanks to Ol' Slim and his merry band of stats-obsessed voters over on Mathematics Stack Exchange for coming up with this brilliantly simple idea. Per venerable tradition, details on how each line-item contributes...0
I'm running a web-based slideshow on multiple computer units. I have a VBScript that runs on startup, opens IE and navigates to a specific page in fullscreen mode. Everything works great, as long as there's an internet connection on startup. If there isn't then the page never loads. Is there a wa...

I need to implement a decoding in the next JSONs:
First variant:
{}
Second variant:
{"one":{
one_data...
}}
Third variant:
{"two":{
two_data...
}}
Fourth variant:
{"two_vector":[
{
two_data...
},
...
]}
To the next enum:
#[derive(Debug)]
pub enum Value {

This code works. Since it has too many loop, loop inside loop, this works very slowly. How can we increase the speed of this program? I am trying to copy a range from one file to another file of same name in different folder. I have folders named "A","B","C"..."G" inside "c:\Charts\1\" & "c:\Char...

First version: Go (board game) in Java
What's new:
I now use (as advised) HashMap<GoPoint, StoneColor> where GoPoint is my "coordinate" class and StoneColor is an enum.
Game allows only legal moves.
Player can pass (skip turn).
Player can choose the size of game board.
Code is more readable ...
