Cool, I don't. iPads are so useful for drawing, and I hate having to use a terminal app on an iPad.

Different horses for different courses.


We can't build a TV from 50 years ago, much less a space rocket.

Because we stopped, we get to do everything over again with hardware from this century.


My point is this path doesn't lead to the future, it leads to the sad state of space between Apollo and this Shark Jump.

The first Orion (nuclear pulse) has a much more interesting story and would have made us an interplanetary species before we had the iPhone. But it was killed by Kennedy, became space wasn't what he was worried about.... And maybe hundreds of nukes in space might make some countries edgy.


Wai how is it weaker, like genuinely?


> and if there were it would be accused as being fake and a ploy from American enemies to discredit them.

Yeah so, the soviets were pretty good at dodging things like that:

At the time they were ~57,000km out and I calculated it was at least 380ms RTT to the ground receiver, so bad but not unusable.


I don't think you understand how a swiss cheese failure happens. They're not independent or semi-independent. Latent failures, expose active failures, like:

"Committed hard to an assumption that was wrong"

Then causes damage to the seawater pumps along the shoreline, and flooded emergency diesel generators.

That causes total loss of AC and DC power.

Loss of AC and DC power causes the reactor to overheat.


Except that there are a LOT of people that want to work in video games (which is the supply) which then depresses the price (wages)

All of my developer friends in the gaming industry have had far worse working conditions then what I've had.


I may have a positive personal opinion of the GDPR, but I ignore all GDPR requests for the website I have that you can just visit, because I don't want to be seen as doing business that makes me subject to GDPR


I live in the present, and not the past, so I'm not sure what your argument is here.


> "we don't want IP's from Frankfurt showing up somewhere in Dubai"

From a network perspective statements like that make no sense. IP addresses don't have any sort of physicality,


They have registration data. Someone could declare they don't want IPs registered to companies from Frankfurt with geofeeds in Frankfurt to be advertised in Dubai.


It’s not how any of it works.

How do you determine to whom an IP is even registered to? They get sub-leased all the time.

The best you can do is check who has administrative control over the prefixes RIR info, but that doesn’t mean that anyone with control is the factual user of the IPs.

You could check the IRR for the ASN and base it on that, but still.

There's also no way to actually know _where_ an IP actually originates from. Only its AS path.

The DFZ contains all prefixes announced everywhere, for the internet is completely decentralized.


> How do you determine to whom an IP is even registered to?

You check the RIR's records.

> They get sub-leased all the time.

With records updated. If not, any consequences from wrong information fall on the lessor and lessee.

> There's also no way to actually know _where_ an IP actually originates from. Only its AS path.

Ping time from different locations on their upstream AS gives a good guess.

Not always + there are no consequences whatsoever.

Plenty of leasing services will just provide you with IRR & RPKI, without ever touching the actual records.

> Ping time from different locations on their upstream AS gives a good guess.

Upstream AS is meaningless if it's a T1 carrier. Ping AS6939. They are everywhere.


Ping a specific address of AS6939 and find out where it is.

They are everywhere. It's a global carrier. Carriers also know no geographic boundaries.
