Why did Truman publicly announce the h-bomb project?

There are some perplexing aspects to Truman's announcement of January 31, 1950. First of all, whatever happened to secrecy? Besides, at the time of the announcement nobody had a clear idea of how to make the superbomb. Scientists figured it was probably possible, but the announcement predates the Teller/Ulam breakthrough. (It would have been embarassing if the announcement led to this being invented elsewhere first!)

The "natural" time to make such a public statement would have been after the Ivy Mike test, at the earliest.

Was it politics? Perhaps a political need to show toughness after the Soviet nuclear test?

DVRF-5NS turned on after power failure (was off)

The light was off, there was a momentary power outage (or maybe several in rapid succession), and the light turned on.

My understanding is the switch should return to its previous state after a power failure.

Something that might be relevant: this switch is a "3 way" paired with a mechanical switch. Maybe the problem was caused by false switch sensing? (But even though the mechanical switch is a toggle, shouldn't the Lutron switch be keeping track of the mechanical switch position? So a false toggle detection should be correctable).

Anyone got "Chime 2" to work?

I have the slim battery doorbell with Homebase2, supposedly compatible with Chime2. But I can't get it to work. In the app under ringtone settings, it says "no supported devices yet". It doesn't make any sound.
