SpaceX hit by inflight Falcon 9 failure

Persona

Re: Data

Yes is does depend if you include both as a unit, and in this context you do.

Persona

Re: Data

Note also that the Apollo 1 fire during testing also destroyed the Saturn 1B it was on just as one Falcon 9 was lost on the pad in a pre launch test.

Plus the unfair but technically correct statistic:

5 space shuttles, 3 successful. 60% success rate (both failures resulted in total loss of the shuttle and death of all seven crew members aboard)

Persona

I don't see any reason for the FAA to ground the rocket over a upper stage malfunction

An upper stage that barely makes orbit and then loses control is a big lump of metal that is going to make an uncontrolled reentry "somewhere" along its trajectory and not necessarily in a safe location. The satellites it launched will burn up but parts of the second stage won't.

Re: The greenhouse effect is so last century!

Re: The power source of the future

There is a lot of lithium. The numbers normally quoted are for reserves, which are currently economic to use. This changes as the cost of lithium fluctuates and also as new extraction techniques are developed.

The huge difference between reserves and resources matters.

Nvidia loses a cool $500B as market questions AI boom

The stock market was invented as a secondary market so people don't need to invest forever. Somewhere down the line, be it in days, months or years you can decide to sell your stock and spend the cash or invest elsewhere.

A great example is pensions. People/pensions funds buy stocks when saving for retirement, these then get sold when the pensions are in payment to fund the retirement.

The stock market joins people who want to sell and those who want to buy. If more want to buy than sell then the price goes up. If more want to sell it goes down.

Wells Fargo fires employees accused of faking keyboard activity to pretend to work

Persona

Re: Whatever happened to measuring output?

I once was unfortunate to work on a high security system that mandated a very high level of formal documentation and review as part of the evaluation criteria. It was interesting to note that that vast bulk of the review comments were raised concerning the first 5-10 non boilerplate pages and also the last few pages. It was pretty clear to me the the only a token random page or two in the middle ever got read.

Persona

Re: Whatever happened to measuring output?

A relative of mine worked out that at his firm tickets for easy problems "scored" equally as hard ones. He then specialized in picking up the subset of tickets that were easy fixes and automated the hell out of them with Python scripts. He generally worked for five minutes every hour on the hour and consistently ranked as the highest performing operator. The remaining 55 minutes were spent watching films and playing games. His biggest worry was that they would notice how quickly he closed tickets. They never did and he was still doing it over 10 years later when the firm eventually folded.

The icing on the cake was that the employer was in the US and he was a Brit living in Asia (WFH) so he paid no income tax.

Persona

Re: Whatever happened to measuring output?

In some instances it's hard to tell if a lack of output is due to the problem being harder, the staff being dumb or the hours being worked low.

I know one chap who is currently employed full time by two firms. As he only has to go into the office one day a week for one firm and the other is 100% WFH with the other he manages to get away with it. He "works" short hours at home too: 9:30 to 4:30 with a least an hour for lunch and gardening. For him WFH is the gift that keeps giving.

Trollface

Re: Pasty keyboard warriors

Advocating blocking older women's accounts is both sexist and ageist. If you restrict it to Republicans you are also adding political discrimination. Your post is also titled "Pasty keyboard warriors" which could be interpreted as a suggestion that they are white too, so lets add racial discrimination too. Fortunately you didn't need to flag them as Christian so we can't add "religious" to complete the set of possible discriminations.

Persona

Re: Are we shocked?

The world is not being burnt to a cinder. A 1.5C increase is not going to do that. 50 million years ago in the Eocene the world was 15C hotter and it didn't burn to a crisp then either. The climate was equable

and it was a good time for life. The oceans were warm and teeming with fish and on the land flora and fauna thrived.

BTW - modelling the equable climate back then is problematic as energy balance models and proxy data differ substantially. From a scientific method perspective this does show that our current climate models are broken.

Research finds electric cars are silent but violent for pedestrians

Persona

I have a mild hybrid. In car parks it's invariably being powered by the electric motor and makes a weird jangly sound like an alien space ship from a 1950's B movie. Does it do it deliberately or due to to some design issue? Either way a chap in the car park this afternoon had a narrow escape when he chose to walk behind my car as I was reversing out. He leapt away smartly warned by the strange sound.

Fun fact. The woman in the Shake'N'Vac advert had a very bad stomach upset on the day of filming that necessitated her sitting on the loo rather a lot. Consequently the advert was hurridly filmed in a single shit.

Re: *Audio*books

The other YouTube advert I get a lot is for a brand of sanitary towel. As I'm the wrong side of 60 I'm pretty sure that they shouldn't put me in a demographic needing that. I'm male too.

Persona

Re: *Audio*books

I have less confidence in Google's proficiency than you. Every time I use YouTube I get shown the same cringe worthy advert about some crap bank account that earns you £5 per month ... for the first 6 months. I'm not dumb enough to switch bank account for a £30 offer, yet the evidence of being served this add many dozens of times suggests Google either knows very little about me or simply doesn't care. At the end of the day it doesn't matter that much to Google. They get paid for slinging adds at people they "claim" are good targets. If they only got paid if the customer clicked through and eventually completed the transaction then it might be a different matter.

Re: Could someone please explain ?

Marketing is not unnecessary it is vitally important. Driven by marketing, research and development or R&D comes up with the right products that can be sold to a target market. Without that guidance R&D is not going to be heading in the right direction so the research would best be described as academic.

UN: E-waste is growing 5x faster than it can be recycled

Persona

Re: Recycling not that easy

At the high end of gov security not only did the operator come and sand the oxide off the platters, he gave it back to you in a bag as he was not authorized to take it off site. You then arranged for the bag of oxide to be incinerated, which was overkill, but gave you that all important bit of certification.

Bernie Sanders clocks in with 4-day workweek bill thanks to AI and productivity tech

Re: Hmm

"increasing productivity is what makes our lives better." True, but UK productivity hasn't increased since 2009 ........

Persona

Re: Hurrah!

Alas, despite all the tech improvements, productivity in the UK has been flat since 2009. This is a big problem because the population is aging and social care needs are increasing, yet we are no longer getting the traditional growth in productivity to support this increase. Consequently living standards are falling to maintain the balance. Putting in new measures that could further reduce productivity before proving any alleged increases due to AI is a dangerous move and could just lead to further drops in the standard of living.

Forgetting the history of Unix is coding us into a corner

Persona

Re: Man pages

Nope with a 10Mbyte hard drive there wasn't room. They came on paper as in "pages", and with the Ironics system I used first (probably Unix Version 8) they even came in half letter binders. I read the manuals cover to cover, which was hard as they were alphabetically arranged. One of the first system calls I read about was "accept(3)" and that was my introduction to socket programming. I had never even heard of "sockets" before. It was utterly meaningless and so was bind(3) a few pages later. Things got a bit clearer with listen(3), but it was not till nearer the end of the manual when I got to socket(3) that I had all the bits (having read read(3) I could guess there would be a write(3). A day or so later when I was in my car that it all clicked into place in my mind and I knew how to use sockets. Reading that manual a second time was so much easier.

When I moved on to Sun systems they were still shipping the manuals on paper. It was quite a while before they started shipping them on CD ROM.

Persona

Man pages

For it to be UNIX it has to have man pages. In the days before the internet there was nowhere else to go for help. If you wanted to learn Unix you read the manual pages. So if it doesn't have man pages, then for me it's not Unix. The reverse however is not true as non Unix systems have copied that rather excellent feature.

Out with the old, in with the new as 100 Starlink satellites take atmospheric exit

Persona

Re: Disposible like BIC or Gillette razors

linger for decades .... a lot of decades, as in millions of years. Proper decommissioning procedure also requires them to be passivated so there is no internal energy left that could propel fragment into another orbit.

Persona

Re: Disposible like BIC or Gillette razors

I agree with your analysis, however there is another factor. Fiber has lower operational costs so it will slowly push Starlink further and further out into the wilderness where there are relatively few customers. This could make it very niche as a regular ISP. High bandwidth to ships and aircraft is a good market but a cheaper satellite cluster could be more competitive on price. However the high bandwidth low latency connectivity to anywhere coupled with the very high resiliency makes it an ideal product for the US military. Compared with the US defense budget, maintaining Starlink is a rounding error. Given the US military as the "anchor" user, Starlink will be able to afford to deeply discount services to its other clients to retain market share.

Persona

Re: Disposible like BIC or Gillette razors

Obsolete geostationary satellites are never brought down. Instead, if possible, they are moved up into a graveyard orbit where they present zero risk to operational satellites.

Apple redecorates its iPhone prison to appease Europe

Persona

I have a sneaking suspicion you don't own an iPhone. Perhaps you don't own one precisely because you can't install anything you want on it. If so great. You can buy an Android phone and install any crap on in you want. You probably already have done, so why do you want Apple to make hardware you can install what you want on? Does your Android experience suck that bad?

Persona

Monopoly?

This is a perfect example of what happens when people with the power to pass laws have too much time on their hands. They interfere for no sensible reason. Claiming it's to stop monopolies and abuse of power and promote freedom of choice rings false as iPhones are less than 25% market share of smartphones in Europe and also globally. If people don't like the way the Apple ecosystem works or their high prices they don't have to buy an iPhone, and they can buy into the Android ecosystems if they want. Similarly if app developers don't like the Apple T&C's they don't have to develop for iPhones.

For the 25% of smartphone owners who like the way the iPhone works, respect their choice and and don't try and turn it into an Android phone or general purpose computers.
