Tesla shows off the AI supercomputer training what it hopes will one day be an actual self-driving car


Re: Testing Neural Networks

One way is to test it in shadow mode on your fleet of vehicles. Doing this over time identifies more and more of the weird edge cases that can be added to the training set for the network whenever the real driver and the shadow driver have a difference of opinion. The dataset is constantly growing and evolving.

The Starship has landed. Latest SpaceX test comes back to Earth without igniting fireballs


Re: Coming in high

From what I saw, the flip happened about 20 to 30 seconds earlier just before 4 minutes - previous flights had all flipped at 4:20, which was an obvious bit of trolling by SpaceX.

Space station dumps 2.9-ton battery pack to burn up in Earth's atmosphere after hardware upgrade


Re: Pollution?

Pretty sure that at the temperature of re-entry, any dioxin produced won't last very long.

Hero to Jezero: Perseverance, NASA's most advanced geologist rover, lands on Mars, beams back first pics


Re: Repulsive!

Judging by the downvotes, there's a lotta people don't get sarcasm.

Chromium cleans up its act – and daily DNS root server queries drop by 60 billion


Re: hang on

As far as I understand, it will speak to the local DNS, but if it doesn't recognise the domain in its cache it escalates it 'to the manager' who knows everything.

SpaceX powers through bad case of wind to nail Falcon 9's eighth droneship landing


Re: 8th Time

I think the reason is that the SpaceX commentators are engineers who get to do the commentary as an extra so they're not professional presenters. Anderson and Insprucker's commentary on the first Falcon Heavy launch was brilliant as they were so hyped by the whole thing. Personally, I prefer it to the naff "god bless America" commentary style that NASA tends to use.

Engineers blame 'intentionally conservative' test parameters for premature end to Space Launch System hotfire


Re: hit their full power of 109 per cent

I think the 100% relates to the full power when the engine is operating at maximum efficiency. Depending on the design you can get more power but at the expense of disproportionate extra fuel burn.

AWS is fed up with tech that wasn’t built for clouds because it has a big 'blast radius' when things go awry


My interpretation of this was that there's switchgear/firmware in each of the racks and a fairly big battery array elsewhere, which does or does not make sense depending on the power supply architecture as a whole.

SpaceX Starship blows up on landing, Elon Musk says it's the data that matters and that landed just fine


You'd also need a runway, and there aren't any of those on the Moon or Mars.

First analysts, now YouTubers put you on blast. Do you A) take it on the chin or B) up fire up the DMCA-o-tron?


Re: Top marks to the author

I wasn't expecting that!

Tesla to build cars made of batteries and hit $25k price tag about three years down the road


Re: Applefying the car

Tesla wipers are easy to control. Single press of the left control stalk, or a single tap on the wiper icon on the touch screen. They also come on automatically if it rains anyhow. Likewise, the de-mist is a single button tap on the icon on the bottom of the touch screen.
