US Spy Agencies

A story on NPR about the upcoming "National Intelligence Estimate" report mentioned that it represented the best work of all 16 U.S. spy agencies. SIXTEEN!? How many people could even name five? The CIA, FBI, and NSA get most of the press. What else is there? DHS is a new one I guess.

I found this site at www.intelligence.gov which lists all sixteen agencies.

Air Force Intelligence
Army Intelligence
Central Intelligence Agency (CIA)
Coast Guard Intelligence
Defense Intelligence Agency
Department of Energy
Department of Homeland Security (DHS)
Department of State
Department of the Treasury
Drug Enforcement Administration
Federal Bureau of Investigation (FBI)
Marine Corps Intelligence
National Geospatial-Intelligence Agency
National Reconnaissance Office
National Security Agency (NSA)
Navy Intelligence

Each branch of the military has its own spy agency, including the Coast Guard(?!) and the Department of Defence. Those and the big 4 mentioned above make 10. Let's take a look at the remaining six.

Drug Enforcement Administration: Yes, those guys have good reasons to be spying around.

State Department: These guys probably don't have their own spies. They (and the DHS) are in more of an oversight capacity, coordinating the other groups. Do we really need two competing oversight agencies?

Department of Energy, Department of the Treasury: These are surprising agencies to find on the list. I would have thought the FBI would handle money laundering, and the CIA would take care of nuclear energy spy-work.

National Geospatial Intelligence Agency: These guys run the spy satellites. And stuff. Cool. But only since 1996.

National Reconnaissance Office: No, wait, these guys run the spy satellites. The NGIA just makes pretty pictures with the data from the satellites. Or something like that. Here's a nice quote: "The NRO established in 1960 ... existence of the NRO was declassified on 18 September 1992."

If that isn't enough, this page lists 38 US Intelligence agencies and web sites. Oh well, I don't think any amount of spying will ever actually amount to "intelligence".

Van de Graaf generator with dangerous wiring

I recently bought a van de Graaf generator from here.

It came with the central column broken at the bottom where the screws attach it to the base. I got them to send me a replacement, but the replacement was broken in the same place. Rather than continue that game I talked them into refunding half the price and kept one of the broken generators. I was able to superglue the plastic tube to repair it, so everything was good.

Then one day I clean the unit, carefully following the directions, plug it back in, flip the switch and ... ZAP! The circuit breaker got tripped. Good thing too, since it turns out that the wiring in this thing is dangerously bad. Instead of using one of the many types of standard connectors for the wires, they are simply twisted together, and an insulating sleeve is slid over the junctions. The insulating sleeve is not adequately secured and the wires can easily pull out of them, and when that happens, since the junction on both wires is at the same place, they short out. The result for me was that the wires welded themselves to the metal strap holding the motor in place, the in-line power switch was melted in the "on" position, and (fortunately) the circuit breaker stopped anything worse from happening.

In my opinion the wiring in this product is dangerously bad, and I would recommend that anyone with one of these generators take it apart (unplugged), slide back the insulating sleeves (before it happens by accident) located under the metal straps next to the motor, and put a couple of twist-on connectors (like they use in home lighting wiring) on the twisted-together wires. You will have much safer experiments afterwards.

Woot!

Got a 6.0 for my GRE essay score!
