Re: It's a good question

Depends on their view and whether they were looking, so they might have glimpsed the pedestrian before or as the other car hit them and done the instinctive inference and slammed the brakes on.

> at which point she was pulled under the engine compartment

The majority of SUVs have this design fault. Going back a few decades it was a feature of car design to have a lower front and sloped bonnet so that animals and people would be thrown on to the bonnet rather than dragged under the car…

Re: Interesting that the police

This raises an important question: do these cars have an obvious off and take manual control switch, like UK buses which have an external fuel cutoff and engine kill switch.

I suspect without some form of standardisation there is no reliable way for a third-party (police etc) to do anything with the autonomous car, unlike cars with human drivers…

Re: My first thought ...

I presume there is also a lack of mobile phone footage uploaded by Joe Public?

130 Mt CO2 Pa Does look very low.

“ The average carbon dioxide coefficient of distillate fuel oil is 426.10 kg CO2 per 42-gallon barrel (EPA 2022).”

So 130 Mt is roughly 305 barrels per year.

It is estimated the world consumes more than 88 million barrels of oil per day…

Re: Carbon sinks

>” I wonder how much charcoal the fires leave behind.”

Very little, remember charcoal is formed by heating wood to over 400C in an oxygen starved environment.

What also needs to be taken into account, is the amount (and source) of energy needed to covert x tons of wood in y tons of charcoal.

Re: Carbon sinks

>” Empress trees are fast growing, and are reputed to capture up to 10x the carbon of other species.”

Useful but not really helpful information.

The problem is trees grow…

Locally we’ve just had a run in with housing developers and planning. They are wanting to fell a avenue of mature trees, they have offered to plant new trees: one sapling per mature tree… we pointed out the maths indicates they actually need to plant circa 1700 saplings per mature tree for the new planing to capture the same amount of carbon as the existing trees (obviously over time the saplings can be thinned).

So all those “we plant trees to offset carbon emissions” are highly suspect.

Re: This is bonkers

>” The costs for climate policies are crippling to our economy and therefore our wellbeing, and for what?”

Never ending growth can only happen in books and the imagination, by all measures we are beyond what our planet can provide and sustain our lifestyle and a 9+ billion population. So the question isn’t if but when will our economy and society crash…

Some experts, ignoring climate change and going on consumption and population growth, suggest circa 2040 when the wheels fall off the current world economic order… [Aside I’ve been looking for more on this, but back of the envelope calculations based on a 1970 report which projected Earth could support 3 billion people consuming 3 Earth’s of resources for circa 200 years indicate 50 years down the road, for 9 billion its 20~30 years… ]

Re: This is bonkers

So for an encore are you now going to prove that black is white?

The IPCC assessment criteria are a joke!

The criteria are more about backing a do nothing approach, once (and there is a big if on whether the criteria really will show this) the criteria are satisfied there is no simple mitigation, it’s hold on for the ride time…

Re: Kudos

>” the infamous 'Hockey Stick'”

I seem to remember the well funded US based denier group that then took the data and did their own corrected work also came up with a hockey stick…

>” evidence of very large populations”

“Large” based on our understanding of the technology and state of advancement back then, minuscule by todays standards.

>” Only if you completely ignore the 'Greening of the Earth’ “

Valid to ignore, because of timescales and human activity. Timescales because the greening happened over geological timescales not human ie. We need it to go full throttle in the next decade or so, secondly humans have shown they are really good at deforestation etc. ie. Cutting back the “greening” and burning it…

>” and none of the supposed 'experts' can demonstrate”

And none of the nutters (or “supposed experts you refer to) can point to a previous advanced society of 9+ billion humans surviving the size of climate we are f potentially facing, BSL we are stepping into the unknown, knowing that the many of the models are based on chaos theory; hence the butterfly wings saying.

Re: Carbon sinks

Yes there are places that “HAVE” forests and similarly there are places which until comparatively recently also had massive forests yet despite all these forests atmospheric carbon dioxide levels have increased massively in the last circa 200 years, because we’ve been digging it out of the ground, burning it and putting it back into the atmosphere…

Re: Hinge & Bezel

It’s been a feature of Dell vostro laptops for at least the last two years. In this case it also elevates the key board to give it more of a slope.

Re: Given the layoffs...

British land now have the monies to do exactly that… expect the planning application for change of use to go in shortly…

Re: Correction

Is that £21m a month or per year?

Some sources think it’s per year, so it represents about 50% of the full value of the lease.

Expect British Land (the building’s owners) to have someone else in the building well within 10 years.

From the comments I think many have missed the joke about the blind faith many are showing to everything AI, and that given AI isn’t by itself going to give any new answers to anything that we don’t already have an answer we will be better off limiting the spread of AI.

That’s why it’s all in storage and why Windscale/Sellafield is managing an increasing pile of nuclear waste…

It’s easy to talk the talk, it’s walking the walk that’s difficult…

Re: First Things, First ..... Take security and data protection seriously.

From the article it seems a huge blind spot in the US thinking is that China has been aided and abetted by the USA’s lack of security culture, as demonstrated by the number of successful UK teen hackers penetrating US military and government computers over the decades. Additionally, the US’s attitude to personal information and data automatically makes it less secure. Finally, the Chine were able to exploit Microsoft Exchange (a made in America by Americans for Americans product) because of the poor quality of development and testing that has and is going into this product…

China has and is demonstrating the courts are just a fig leaf when it comes to security.

>” the limitation of only 3 non-overlapping channels in the most commonly used 2.4GHz band.”

The problem (*) that strategy was addressing largely went away with the move away from the initial 1~5mbps signalling. But things enter the collective conscience and become firmly embedded and set in stone.

There were papers based on live experiments published on it circa 10~15 years back. Also the original Aruba office AP deployment used a single channel across multiple APs…

Yes, there is some interference but it will typically be less than 5%.

Also with higher speeds requiring more channels, channel conflicts become unavoidable and thus the transmission design has to take this into account. If you think of the carrier wave as a corridor, a collision only happens if the bit of data my AP sends - which normally my device antenna receives, occupies the same airspace at the same time as the bit of data from my neighbours AP - something which happens relatively rarely. Transmit and receiver diversity reduces this problem as my device is receiving the same bit on multiple paths.

I run my home WiFi on channel 9 (2.4ghz) and a similar channel on 5ghz not normally used by ISP supplied routers (thus disabling its antiquated frequency hopping algorithm) and everything works fine, last time I looked the error/retransmission rate was circa 1 percent and the neighbours Sky, BT et al routers were happily using their default channels that overlap with mine.

[Aside: I also disabled the sub 10 mbps connection speeds - if all your devices are 802.11g or better this won’t cause a problem. Whilst I could have set my default channel higher, many devices over the years - including HP and Dell laptops don’t scan the non-US channels, but once they had associated will switch to using non-US channels. Similar considerations apply to the 5ghz band and the DFS impacted channels.]

(*) The 3 channel limit on 2.4ghz was due to US frequency/channel availability, for most of the rest of the world it was 4 channels. Interestingly, I see many ISP routers eg. BT also limit their use of 5ghz to 3 channels.

Re: Give me more range, not more speed!!

Correction that should be 802.11 not 801.11.

Re: Marketing....

> Except that double glazing has clear and quantifiable benefits..

Which were compromised (in the days before uPVC) by fitting in aluminium frames which lacked a thermal barrier..

What I detest about the companies (especially the majors) selling double glazing, alarm systems, solar panels, paving etc. is their rip-off add it on to take off approach to pricing and offers only available if you sign now (hence why they ask to have all with an interest i the property present when they do the “survey” and “quote”.

>” The fibre terminates in a box that's got an RJ45 and (optionally) a phone socket on it.”

The Glide box has neither, it’s just got two LC/UPC Simplex outlets.

Glide will give you a choice, use their router or pull the fibre SFP module out of their router and put it in your router (or buy the relevant module so you have a spare (*) ).

Obviously, if there are faults on the line they expect you to reattach their router so they can do end-to-end diagnostic investigations.

(*) plug for FS.com: give them the serial number of the supplied module and they will tell you which modules are compatible.
