Reverse DNS queries may reveal too much, computer scientists argue


DNS or rDNS and PTR records

If you know the hostname you want to track then it is much easier to use DNS.

myprecious.somedomain will always show the IP address of myprecious whenever it still has a valid lease.

So this is as much a DNS as an rDNS risk.

rDNS is just one way to find valid hostnames, but any (brute force) DNS query of a domain would give a more complete overview.

And if rDNS is considered a greater risk than DNS then disabling the creation of PTR records for DHCP leases solves that problem.

Update your Tesla now before the windows put your fingers in a pinch



Reading the article and the comments I have only one question:

Does no one see the beauty and ingenuity of this?

With a software update a window safety system can be fixed.

The same was done in the past with brakes on the Model 3.

And many many more things have been improved on Tesla's without any effort/involvement from the owner.

There is a BIG IT angle to all this and its completely ignored by everyone.

Underwater datacenter will open for business this year



Depends on the speed of the heat dissipating from our planet.

If you heat the air it is easier dissipated than heating an ocean.

I don't know whether this is easily measurable though

One man's battle to get patent rights for AI inventors in America may be over



I see that a lot of people believe "AI belongs to us". Maybe I am mistaken but weren't the experts afraid that AI might take over in the future.

AGI is a little bit scary, but if we get there then those systems will learn faster than any human collective can do.

Another argument used above: AI needs input from humans. Where would the humans be if they did not get input from other humans (this starts before you are born).

AI needs input as well, this will be given by humans for the time being but books (paper or digital) and other sources of information (the key word here, one other example of information is the Internet) are already and will only be more available.

If the AGI experts are right once we get to AGI systems most progress will be made by AI systems, not humans. It will be made by using all the information the system(s) has, whether this information comes from humans, books, other AI systems, sheep or anything else.

Tesla Full Self-Driving 'fails' to notice child-sized objects in testing


Re: Full Self Driving (FSD) was not even engaged!

Thanks for the update, it is probably the best update I have ever seen.

FSD is not easy and only time can tell how we will get there.

For the time being extreme caution is needed when using these features.

NASA's Space Launch System rocket is on track for August 29 liftoff


Re: robotic missions

I think you took the estimated costs, not the real costs.

Currently the costs are at <quote from article> " $23 billion and $2 billion per launch"

So that would be 25 billion after launch.

Presuming the $500M is correct that would give us 50 missions, again excluding the bulf discount.

Broadcom challenges Nvidia's Spectrum-4 with 51.2T switch silicon


Explain the math please

"Every two years we've been doubling the bandwidth of the silicon," Pete Del Vecchio, Product Line Manager, told The Register. "Since 2010, we now have an 8x increase as far as the bandwidth

Speed doubles every 2 years, so 12 years gives 6 doublings, so 2 to the 6th = a 64x speed increase.

Intel, Amazon, and SpaceX asked to tuck into DARPA's Space-BACN


Interesting, let's hope that combining forces and some help from the biggest competitor is actually going to result in actual services being delivered and some competition for Starlink (the biggest competitor).


Can you explain why OneWeb is going to happen?

I think in Ukrain they are using the try/fail/learn/try again method very well against a stronger opponent.

China details relocation plan for up to five million datacenter racks


Re: I'd be amazed if they intend to power them with coal.

Please explain better what you are trying to say here! 100Mwh in 1 hour and 15 minutes means 80Mwh per hour means 1.9 Gwh per day (but the battery is not big enough for that of course),

The Hornsdale Power Reserve (phase 1 only) can (is contracted to) deliver 100Mw, for 10 minutes, then throttle on with 30Mw for 3 hours minus the 10 minutes,, a bit more than 0.96 Mwh/day:

16.6 + 84.9 = 101,5 Mwh/day

With the extra 50% of phase 2 that becomes about 50% more probably.

Microsoft pushes ahead adapting Azure for 5G telecoms after swallowing AT&T's Network Cloud



Let's hope that AT&T is the only provider moving to Azure, if more move over and Azure has an outage again it gets pretty dark out there!

I for one have never received a missed call.
