Amongst other news outlets, CIO reports on a hacker attack on the German parliament (Bundestag) that occured four weeks ago and is still ongoing:
Trojans introduced to the Bundestag network are still working and are still sending data from the internal network to an unknown destination, several anonymous parliament sources told German publication Der Spiegel.[German]
All software and hardware in the German parliamentary network might need to be replaced[1]. More than four weeks after a cyberattack, the government hasn't managed to erase spyware from the system, according to a news report.
Some MPs have concerns to call experts from the foreign intelligence service, the Bundesnachrichtendienst, for help, because the agency would gain access to the legislative process, a possible violation of the principles of Separation of Powers.
[1] Apparently about 20.000 machines are affected

A carpenter once explained to me that you cannot make concrete out of beach sand; rather you have to grind up rocks in a ball mill. That makes for sand particles with lots of nooks and crannies that enable the solidified Portland cement to bind far more effectively than is the case with beach sand, which are worn round and smooth.
He told you some bullshit, maybe he believed it too! You don't want to make concrete with SANDSTONE. You want to make concrete with LIMESTONE. It has absolutely nothing to do with "beach sand".

You don't want anything in concrete that will absorb lots of water in climates that freeze. Guess what happens then?
However during the great depression, it was common to use beach sand. This had the eventual result that a bunch of houses slipped off their foundations in Santa Cruz County during the 1989 Loma Prieta Earthquake.
They slipped off the foundations because they were not fixed to the foundation. Or foundation had not rebars, which is very similar. Or maybe concrete was too weak - not enough cement. But it has nothing to do with sand, especially in California.
You do not want to use sand because it COSTS you more. Sand has more surface area than crushed granite or limestone. And cement amount depends on that to maintain strength. The only place where you use sand is brick laying because you need a thin layer of glue. Anyway ...
As to you comments about crypto, no one cares about crypto. And most that do, don't know what it is or how to use it. Crypto is not a "sexy" thing to work on. Look at current state of IPSec or DNSSEC for some hints.

Just to correct my mistake, BOTH sandstone and limestone are shit. Both absorb water. Limestone is just used to make cement.
The most common fillers used include *smooth* river rocks (granite) or other granite gravel.
