Re: Sinclair pocket calculator

I think it's a bit harsh to call someone a "liar" because they mis-remembered something from over 40 years ago.

Re: Sinclair pocket calculator

It's a Cambridge Scientific - white. I didn't know there was a different one just called Scientific - sorry for any confusion.

For clarity, I was replying to two different posts.

SQRT(36) = 6

e^(ln(36)/2) = 5.9999

Re: Sinclair pocket calculator

I just dug out my Cambridge Scientific.

SQRT(36)=6

SQRT(2)=1.4142135

SIN(52 degrees)=0.78801

The trig functions are truncated to 6 digits but others aren't. It takes 2.2 secs to do the trig function, but the square roots are instant.

Calculator

I've still got my Cambridge Scientific calculator. The power switch went a bit dodgy after only a couple of months, but it didn't deteriorate any more after that and the calculator is as good as it was in the 70s when I got it. Mine must have been a second version because my mate got one a few months before me and the numbers wore off the keys of his after a year or so, which has never happened to mine. I remember it being a battery hog and having to use alkaline batteries, which were quite expensive on paper-round money!

Replaced with an HP-11C when I got my first job - which is also still going strong and runs for ever on 3 button cells.

How does it work?

Something I've not been able to work out from the coverage so far - does NSO retain some control over it's product after they have sold it? The seem adamant that many of the phone numbers on the lists which the press have published aren't targets, which implies that they have knowledge of their customers' targets. I sort of find this hard to believe, but also can imagine that they'd want to keep some sort of control of the product, given how dangerous it could be if it got into the wild. Then again, if everything went through their servers that could bring its own dangers!

Anyone know?

I'm feeling lucky: Google, Facebook say workers must be vaccinated before they return to offices

Re: FREeDomZ

Bollocks. When I was a kid the NHS was barely a decade old. When the doc told my mum it was time for my polio, measles, whooping cough and mumps vaccines she didn't go to the library to find a million reasons not to vaccinate me. She didn't wait until she'd been to the beetle drive that week to canvas the views of her friends. She listened to the doctors and, thank God, got me vaccinated and was grateful that she didn't have to pay. There was no hesitation when it was time for my TB vaccine because she knew people who'd died from it and she thought that a hole in my arm was better then coughing myself to death. There's a good chance that I wouldn't be here today if my mum and all the other mums since then had been as much of a twat as some people are today.

Nothing's changed from a medical or scientific point of view since those days over half a century ago. All that's changed is that in the past ten years or so people have access to much more information and some of them seem to give as much weight to the web equivalent of a bloke down the pub as they do to doctors. If it weren't so fucking serious it would be funny and if it only affected their lives then it wouldn't matter to me. Even ignoring the arguments about herd immunity and responsibility to one's community, a death never affects "just me". It's a devastating impact on a family to lose a parent, child, sibling, spouse - with results ranging from mental health issues to poverty and destitution. When the cause of this potentially-avoidable death is an opinion formed by reading shite on the web instead of listening to doctors then that is abuse.

Re: Liability

Well, given that they also know that more of their employees might suffer "tremendous injury" - including death - if they don't get vaccinated maybe criminal prosecution should be considered for board members who don't insist on their employees getting vaccinated.

Re: Causes

Good work - and maybe not surprising. Releasing good code is expensive. I guess that an analogy is safety critical development (SIL, SW01, DO-178, etc). These standards don't just focus on development, coding and testing, but on the company environment and processes that surround and support them from design concepts to in-service support. It makes SW development in these environments expensive, a bit less fun sometimes, and it makes it much harder for a director to shout "just fucking release it or we'll miss this quarter's numbers".

I don't think we'll ever see security equivalents of these safety standards, partly because of the expense but mainly because of today's expected rapid turnover of product and introduction of new features.

Re: "Needle Nazis"

"Why is that? There's no good reason for it."

They make money from it and they don't care about anything else. They've already got insane amounts of money that's unspendable in a dozen lifetimes but, apparently, that's not enough for them and a few deaths here and there apparently don't matter as long as they continue to make money. The anti-vaxxers are also more profitable than normal people because they are more gullible and therefore susceptible to ads.

Re: Where's the biggest profit?

@Version 1.0: that might have been the case up until a short while ago, but insurance companies are starting to back away from cyber security. AXA France recently stopped underwriting ransom payments. Other companies are now excluding ransom payments from their cover and the cost of premiums is rising. The security requirements for getting insured are increasing in some sectors, which can only be a good thing.

I think we'll soon see the end of organizations having poor security and relying on the insurance pay the ransom to get their data back.

It's power source is solar and batteries, so the PCU shouldn't need any big caps for taking low AC out. Most of the spike and noise caps will be local, rather than at the PCU.

UK govt draws a blank over vaccine certification app – no really, the report is half-empty

Headley_Grange Silver badge

Re: Here in the EU...

I don't know if the UK is struggling. I had my vaccines and they appeared on the NHS app a few days later. I've got Covid passes on the NHS app on my phone and I've downloaded pdf copies which, like you, I've copied to cloud accounts and also printed out just in case. One thing I don't understand is that the UK passes are only valid for a month, after which they have to be downloaded again. I assume it's in case policy changes or they discover something about vaccine efficacy.

Re: OPtion?

Given that the NHS app uses QR codes for both the travel and event passes I assumed that there'd be a corresponding reader or app that could validate them, thereby making fakes much more difficult. However, a quick Google around didn't reveal anything that can be used by pubs, clubs, etc., and there's nothing obvious in the Apple app store, so I don't really understand how this is going to work properly. The passes can be downloaded as pdf., for printing out by users without a smart phone, so once you've seen one it's trivial to mock up a fake.

Maybe the validation app/reader is a work in progress?

Re: Lead by example

It's not just low pay, which is why I wrote "labour costs". It's also the fact that the workers don't get holiday pay, sick pay, p/maternity leave, weekends off, fire doors, employment rights, etc. The main savings in offshoring work isn't the salary, it's the fact that the employer has no overhead costs related to worker rights and safety.

Western governments will never address it because the main cause of it is that we, the consumer, choose the cheapest product with the fastest delivery and we don't give a toss if it's made by a 13 year-old girl who should be in education instead of working 70 hours a week in a dangerous sweat-shop for a few dollars. Even if the UK government were able to put massive import duty on goods made by workers who don't have the same workplace standards and protections that UK workers get (or, at least, used to get before zero hours and contracting out) then UK consumers (voters) would be angry because they couldn't buy cheap clothes in Primark and throw them away after a couple of wears.

BTW - I infer from your post that you think that the vision of a shopless society is a good thing. I think it's a very, very bad thing.

Re: Lead by example

Imagine the alternative scenario where no shops exist at all - just warehouses with staff on crap contracts and zero hours delivery drivers. Your parcel of [food, clothes, laptop, medicine, lunch, .....] arrives and it automatically Facetimes a salesperson located in the country with this year's cheapest labour costs. Same experience, but from the comfort of you own HMO shit-hole that you're about to be evicted from because all the decent jobs have been offshored and your zero hours job delivered exactly zero hours this month so you can't afford the rent.

Tough Call

I managed development teams for many years and have been responsible for recruitment, development, appraisals, discipline, pay-rises, promotions, mentoring, etc. Many of these depend on seeing how people work, not just in a project team, but in the company, with customers, with awkward people, with directors (!)....etc. An engineering graduate will be taken on mainly because they got a good, relevant degree. But they might be destined to be a technical leader, a systems engineer, a project manager, a test lead, a function manager, a commercial officer......etc. For many of these roles I'd find it hard to judge their potential if I only ever saw them on zoom and when they came to the office for project-specific meetings. I had a guy who was desperate to move into "management" but delegating most of my work to him while I had a week off disabused both of us of his suitability. Another engineer's potential as a leader only became obvious when he diffused a difficult situation in the canteen one day - nothing to do with work.

Also, shit but true, for the vast majority of engineers, their pay rise will correlate strongly with their personal attendance at work.

I'm an old git, and I assume that with enough time, thought, tools, etc. that things could be made to change. Problem is, as the Apple case shows, most of today's managers are also relatively old gits and I don't know if you can teach an old git new tricks.

Change vs Configuration

Getting an organization to think in terms of configuration management instead of change management is key, in my experience. Change is just one aspect of configuration management and if you can get the whole team - including marketing, support and senior management - to understand the configuration needs of a product it certainly makes change management easier and will reduce change and support costs.

'Vast majority of people' are onside with a data grab they know next to nothing about, reckons UK health secretary

Theoretically...

It's obvious to me that collating, organizing, analysing, mining, AI-ing all the NHS patient data is a good thing for health research, society an, potentially, me. I'm all for it.

It's similarly obvious to me that insurance companies, social media sites, news sites and criminals getting access to the same data is a bad thing.

If someone gave me a rock solid guarantee - air gapped data with crown jewel security and with the regs written in criminal law backed up by jail terms for politicians past and present in the case of breaches and real £££money compensation for citizens then I might, just might, consider giving them access*

Until then, they can all fuck off.

Re: Carbon neutral

There are still a lot of challenges in making hydrogen power practical for everyday, non-commercial use. The efficiencies of producing it aren't great, but if they're done with excess green energy then that shouldn't be a problem. It still has to be transported and in order to do so, and to use it, it needs to be compressed which is expensive in ££ and energy terms. Hydrogen also produces significant amounts of NOx when burnt in air in an ICE, so exhaust gas management is still a problem. At normal pressure and temperature hydrogen has a much higher energy density per litre than petrol or diesel, but when compressed to a car-sized tank this reduces significantly to almost a tenth of that of diesel. Fuell cell EVs would avoid the NOx problem but would still suffer from the drop in energy density due to the compression.

Assuming you could get it, the insurance for keeping your car in your garage might be very expensive unless you've made significant mods to cope with hydrogen leakage from your car. Hydrogen cars would almost certainly be banned from underground car parks and most enclosed parking.

Some of the above are tech challenges that might be overcome and some are laws of physics that might be more of a challenge. Aberdeen has been running a fleet of hydrogen fuel cell EV buses for a while, so there's hope, but I suspect that we're in a VHS vs Betamax situation at the moment.

Re: Wouldn't it be simpler to just get rid of NI

If dividends were company expenses then I could take all this year's profit as dividends and therefore pay no corporation tax at all. Dividends are paid from taxed profit.

Headley_Grange Silver badge

Pennies and Pounds

For an independent contractor avoiding NI (12%) and whose employer is avoiding employee NI (13.8%) then the treasury is losing 25% of the gross salary up to about £60k . That's not pennies.

You could make valid arguments about where that "loss" sits in the system and whether or not the treasury is recouping some or all of it another bit of the tax system, but, as others in this discussion have noted, therein lies the problem - the tax system as it relates to income for individuals and companies is too complicated.
