Tesla's Autopilot is losing out to Ford, GM in self-driving tech

Everybody's so different...

Bringing cakes into the office is killing your colleagues, says UK food watchdog boss

Roger Greenwood

Some people...

... when they walk into a room, suck all the joy and fun out the atmosphere. Can we ban those people instead of cake? Would be great for morale (sorry, "mental health").

I know the BOFH will have a better method of dealing with them, but some of us are too timid for that.

"composable infrastructure"

I read that as compostable and somehow it made more sense...

Move over, graphene. There's a new super-material in town: Graphullerene

Re: Graphene is actually

"pushing over a megawatt"

Yes, good point. To push 1000KW at normal UK LV supply voltage (400V) would be around 1400A, 3 phase. That is some plug-in connector.... (around 3 x 240sq.mm cables per phase). 11KV to your car anyone?

Japan lacks the expertise for renewed nuclear power after Fukushima

Roger Greenwood

"..has declined by 45 percent.."

Losing nearly half your skilled workforce in 11 years, that is a heck of a churn. I suspect one of those numbers has been exaggerated - some may be coaxed back.

Forget the climate: Steep prices the biggest reason EV sales aren't higher

Roger Greenwood

Re: "a strong desire to reduce refueling costs"

Pretty good summary. I would also say that at the moment once you get an EV you also have a whole new hobby:- route planning. It's just a mess of charging systems at the moment in the UK, probably the same everywhere.

Perseverance rover drops off first sample tube on surface of Mars

Roger Greenwood

Re: Oh yes I see now...

I'm thinking about a coin operated robot trundling up huffing about foreigners coming over here and leaving litter (a la "A Grand Day Out"). Where did we leave those sample tubes again?

In praise of MIDI, tech's hidden gift to humanity

You're all talking about electronic whatsits...

Two signs in the comms cabinet said 'Do not unplug'. Guess what happened

Re: Years ago, working for an airline in Toronto.

I worked on a TBM many years ago, similar pressure in the head. They didn't employ anyone who had worked as a miner in the UK as they were "too safety conscious". As you say, takes a special breed.

Roger Greenwood

Don't forget mischief

Yes, yes idiots are everywhere, but so are naughty folks. I have an e-stop outside a lab to kill the power, for emergency use only. Labelled of course, but even so it kept getting pressed with no one admitting to it. It now has a very sturdy steel cover over it, painted red, screwed to the wall so hard to accidentally hit. Still gets pressed.

FAA wants pilots to be less dependent on computer autopilots

Roger Greenwood
Happy

Re: Oh dear

I had a go in a light aircraft last year, first time at the controls. All I can say is my respect for pilots has not gone down.

Flying the plane was easy (nice sunny day), dealing with the radio, ATC, Nav, fuel, traffic etc etc makes the workload immense for a single pilot and I now understand better why 2 in the cockpit is a really good idea. Splitting the workload and adding automation is just a no-brainer when scaled up to a proper plane. Thanks to all the engineers and pilots who continue to make flying as safe as it can be.

Elon Musk issues ultimatum to Twitter staff: Go hardcore or go home

Yup, "no such thing as bad news" has been used before and sometimes it works. Many predicted that no sane country would elect someone like DT but look what happened (and the UK did the same with BJ). Self publicists are very popular with a certain section of society, that drives attention which attracts the money. I'm not betting against an evil genius :-)

Kudos to the huge team that runs the account...... :-)

I think of it as a great source of entertainment, sort of like the red top newspapers in the UK used to be 40 years ago. There is some truth there, but mostly exageration, sensationlism, shock tactics etc. Oh, and a lot of funny stuff, but that is available from many other places.

If, however, you want to argue with a pig then dive right in, you will come out very muddy and maybe eventually realise that the pig likes it (old but good).

p.s. keep Dabbsy in the sea for me.....

UK government in talks with datacenter operators over blackouts

Roger Greenwood

Day tank + bulk storage

Isn't that the way it's done? Day tank good for a few hours, very local to generator(s), re-filled from bulk storage in a more accessible location for the tanker. Bulk storage good for 7 days at full chat, anything else is not really a backup.

Perhaps I have only ever dealt with folks who do it properly . . . .

More than 4 in 10 PCs still can't upgrade to Windows 11

Roger Greenwood

Re: 40% can't run Windows 11...

It's not in anyones interest to run such an ad, other than those with a grudge and no money (me included). All those involved in shifting computer kit make money by promoting MS. No money to be made promoting "free stuff" so it won't happen.

People are coming out of retirement due to cost-of-living crisis

Roger Greenwood

Re: Not great news for youngsters

Maybe the oldies can teach the youngsters a thing or two about attitude, reliability & responsibility. It sometimes seems that these are no longer important if you still live with your parents. Not all, obviously, but too many.

Re: Email remains the most used communication method for work

"Fuck that for a game of soldiers." A much underused phrase, thanks for speaking up from the trenches.

p.s. any day now many folks will get their new gas bill (projected) and be glad to go back to a warm office rather than keep the heating on all day at home, what's that phrase again?

Meta, Google learn the art of the quiet layoff

Re: You can increase productivity if you fire the right people

"...negative work - their "work" causes more work for others!"

This applies to all who make mistakes and is worse than many think.

Example:- mistake made - throw away, start again - cost 1

second attempt - cost 2

but while making second attempt you are not doing what you should - cost 3 and other jobs now run late!

In many industries this is very hard to fix.

UK's largest water company investigates datacenters' use as drought hits

Roger Greenwood

Re: Hosepipe bans

Given that the water is under quite a high pressure, contamination is not a concern until you shut the valve off to fix the leak. Several bar usually, hence water spouts and blown roads in extreme cases.

I agree the real issue is the cost in terms of resources, other chemicals, energy used to treat it etc.

"because the switch contacts were under-rated"

This is all of enginering. It is easy to make something strong enough, but we also have to balance cost, or in the case of rockets, weight. So everything has to be JUST good enough. No more or it won't fly/sell.

Switch contacts are a good example as they also have a life dependent on use (load vs switching operation count) so they wear out. Getting all that right is not easy, fair play to the vast numbers of engineers who do.

Where's my tricorder?

Sage accused of misselling perpetual licenses it knew would soon be obsolete

Roger Greenwood

Clearly you don't work with accountants. Nothing happens fast in that world, especially change...

Also if your audit company uses Sage it's a big wrench/hassle to switch. Sage know this better than anyone.

Still, if you push folks hard enough eventually they will walk away. We have been Autodesk free for a decade now for the same reason.

Copper shortage keeps green energy, tech ventures grounded

Roger Greenwood

Re: 3rd most Abundant element in Earth's crust should be used more ?

As pointed out by others, aluminium is used in many places instead of copper either to save weight or cost. There are many areas where this is not sensible/cost effective e.g. requirement for high current density (e.g. motors) or strength (cables and swithgear). UK DNOs use it quite a lot underground. So cost will decide, as with most things.

"..so structures would need to be about 59% physically larger by volume to compensate." This is what is known in the trade as "bollocks". The cable may be larger, the structure not so much.

What to do about inherent security flaws in critical infrastructure?

Roger Greenwood

Re: A little knowledge.....

Yes industrial plants (in most of the world) have hard wired interlocks/protections and will fail safe, but that can still be disruptive in the short term. Turn off the electricity to a water treatment plant and folks go thirsty pretty quick (hours/days). Luckily there are also contingencies for this including manual overides so I'm also not really worried. Your domestic smartmeter however - if anyone cracks that we are doomed....
