If you static fired without payload, you'd then have significantly longer between the static test fire and launch (during which something might break) and you'd need to lower the rocket to horizontal to attach the payload and raise it again, again with the potential for breaking something. You'd also have each launch keeping the launch pad occupied for longer.

So, it is a trade-off, and you'd need an intimate knowledge of the rocket and launch operations to know whether SpaceX's choice to test with payload was correct.

A DDOS attack does nothing to attack the integrity or security of the data. The success of a DDOS attack only indirectly calls data safety into question - if they were not able to defend against DDOS, perhaps they're also not good enough to maintain security.

As an aside, I'm currently living in Australia, and the site worked fine for me at about 6pm.

Pure water will not accumulate radioactivity. With one exception, there is no reaction with hydrogen or oxygen to make a long term radioactive nucleus. 16O+n->17O (stable). 17O+n->18O (stable). Very rare 18O+n-> 19O, half-life 26s. 16O+p->17F, half-life 65s. Etc.

The only exception is 2H+n -> 3H (tritium, half-life 12.3 years) but the cross section for this is very small, and H2 (deuterium) has very low concentration (0.01%) in ordinary water.

So leave your irradiated pure water for half an hour out of radiation, and it will be fine.

Contaminants in the water could accumulate long term radioactivity. If this is enough to be a problem (I'd bet it isn't), you'd need to purify the water before use.

Comment I hit this limit once in the Unix world (Score 1) 260

I was at a company which developed a large CRM application and I was the person who tarred up software updates to send to sites. A small part of the application was in Java, and the Java programmers were enamoured with class names which emphasized descriptiveness over brevity. We ended up with some files where path+filename exceeded 255 characters, and tar broke. My fix was to tell the programmers to shorten their damn file and directory names. (This was about 15 years ago, and it would have been Gnu tar. )
