Starlink offers 'unusually hostile environment' to TCP

But... what were the problems experienced, this is a highly theoretical discussion so far.

Re: What's his definition of hostile

Re: Neutral?

Yep, pressing the brake overrules the accelerator, car comes to a normal stop.

Re: Neutral?

Actually, this is all drive by wire, no need to stomp, just press the brake and all juices stop flowing to the motors.

And the truck comes to a normal stop.

There are videos of it out there.

JetBrains TeamCity under attack by ransomware thugs after disclosure mess

Re: Well, no

This is not about users, this is about companies that are customers of JetBrains. So JetBrains can contact them and advise to patch ASAP, explaining why. And then companies normally act. I have seen similar actions being taken by other vendors.

I think Rapid7 wanted to get the credits for finding the vulnerabilities. That is OK, but don't publicise ALL details, don't throw JetBrains under the bus because they are not communicating correctly. CVEs without details should have been published on day 1 of patch availability, but not full details. From day 1 the companies/customers can patch, so same or next day (change procedures) or wait longer at their own risk.

The best solution is to work together, this is a good example what happens if you don't!

Google dragged to UK watchdog over Chrome's upcoming IP address cloaking

Well, the first hop will be Google, so Google sees the client IP. It also sees what you want to connect to before it sends it on to the second proxy.

So Google sees all connection info. I don't see how to prevent the first hop from seeing all info.

The second hop won't see the client IP, so the second hop is indeed in the dark about individual client connections.

BUT: All only works if any data (so not the IP header, but data layer) is properly inspected to prevent IP leakage in the data part.

Oops, this is not possible as all is end-2-end encrypted.

Poloniex crypto-exchange offers 5% cut to thieves if they return that $120M they nicked

So any "thief" needs access to either my mobile or my card.

Cisco's Duo Security suffers major authentication outage

Where are the juicy details from the engineers

The update from Cisco is really helpful:

"Updated to add at 2345 UTC

In a statement to The Register, a Cisco spokesperson told us, "Cisco’s top priority is the satisfaction and support of our customers."

This is 100% marketing BS, apparently it is OK to provide no actual info.

Starlink is currently available in your area!

No contracts. Try for 30 days and, if not satisfied, return the hardware for a full refund. Shipping times are currently estimated to be 1-2 weeks.

Costs $120/month, so cheaper and a lot faster. Just have to pay for the dish.

SpaceX's second attempt at orbital Starship launch ends in fireball

Grow up

Re: Today's SpaceX Success

How much money was spent before the first Saturn V flew and how much money was spent before Starship flew.

These are different design methods that can't be compared!

SpaceX tries to (and has) reduced costs of access to space.

Starship is the next big step in achieving cheap and reliable space flight.

I am happy!

Re: Complexity ≠ Reliability

Fortunately it worked for SpaceX, with 3 more engines than the N1

Re: Starship hasn't had the most successful history?

Landing will be important as well, also to become more cost efficient.

But SpaceX sets realistic target poles, achieves them and moves the poles again.

For the Booster launch I think the poles were reached and will be moved again for the next launch.

And on and on and on.

Re: Wrong

Are you trying to be funny or are your comments meant seriously, it is difficult to tell.

If you are serious, all upper stages of Starship went up, which is what all others can do as well. No one else can land anything bigger than a needle compared to Starship.

So respect what they are trying to achieve, and what they in the end will achieve.

Falcon is now flying twice per week and this is only possible because they made reusability happen.

Re: Starship hasn't had the most successful history?

Same goes for the reverse, it is actually even worse, being used to litres it is difficult to handle different gallons etc.

In the metric system a litre is a litre and a kilometer is a kilometer.

Search for "brightness"

Re: This is a worldwide issue

Well, me thinks that if the satellites are made less reflective and use the proper frequency bands in the US they will do the same in the rest of the world (most likely).

Also Starlink has always been cooperative in solving this whole problem in the first place, the satellites are already much less visible than at the start.In that sense the headline is a little bit childish, there was already an agreement from 2019 and it has been updates as the Starlink Gen 2 satellites have more technology onboard, lasers for example.

And for other countries, yes it would be better to have a world wide space/science organisation handling this. For now: if you have any questions or requirements contact SpaceX.

Why did Microsoft just buy fiber optic cable company Lumenisity?

Or is it getting better fast....

From the article https://www.southampton.ac.uk/news/2020/11/hollow-core-fibre.page:

"Their first fibres had attenuations of 5 decibels (dB), i.e. only 30% of light transmission, for every metre of fibre. New physical understanding with contributions from the worldwide community, and substantial development in fabrication technology led by the Southampton team, have now led one of the fibres reported in this study to improve this by a factor of 10,000 by achieving an attenuation of only 5 dB every 10 kilometres."

So that is 0,,5 dB /km, getting close to normal SMF already, and they think they can beat SMF in the long run, interesting to see how that evolves.

The one question I have is how are you going to splice such a cable without blocking the core.

Lumen to double size of US network with six million extra miles of fiber

Neuralink's AI brain chip could be in humans within six months claims Elon Musk

Re: Marketing fail

I think that is correct, but I also think there are a lot of people that can benefit greatly from a version 1, like people that lost control of an arm.

Then v2 is for people with a spinal cord injury, hearin loss etc. v3 for vision, v4 for people with some sort of brain malfunction/disorder and then at some point v14 will bring us some simple form of AGI.

Most will want to wait for version 69.

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

Beauty

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.

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

AGI

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

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

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