I was hypothesising the subconscious reason why Douglas Adams would think "42 will do". I find 42 funny for the conscious reasons I stated.

It's perfectly possible this did not apply to Douglas Adams. But a hypothesis around "eek I didn't do my homework but I winged it" seemed plausible for him.

But why did Douglas Adams think of 42? My theory is that it is from "times table" memorisation questions.

Back in the day in the UK we learned "times tables" at school as a verbal by rote memorisation technique. For each "times table" you memorised up to "times twelve". And then the teacher might ask you in class the answer for a table you were supposed to have learned.

First one to learn was "two twos are four, three twos are six... twelve twos are twenty four". (I'm writing out the numbers rather than using numerals because this was specifically a spoken recitation).

Then you learned the three times table "two threes are six, three threes are nine, ... twelve threes are thirty six".

The four times table is a selection of the two times table up to "six fours are twenty four" and then the next member "seven fours" is an easy addition from 24 to 28.

The five times table is obvious.

The six times table is a selection of the three times table up till "six sixes are thirty six".

Say that (emboldened by the obviousness of the five times table) you didn't do your homework and verbally memorise the six times table.

And then the teacher asks you what are "seven sixes". You are acutely aware that this isn't in your verbal memory (as it would have been if you had done your homework as instructed). You add 6 to "six sixes" which I calculate as "use 4 to get up to 40 then the other 2 are the units so 42".

You say "seven sixes are forty two". There was a one second panic while you worked this out instead of just reciting the rote memorised fact.

But it's the right answer.

Tension then resolution - that is why 42 is the answer to the ultimate question.

The book "how to lie with statistics" (1954) was written before tags like /s were invented. Referencing "how to lie with statistics" is an indicator that the author is trying to avoid common pitfalls in statistical reasoning.

I own an inherited blue Pelican paperbook copy from my pharmacist grandfather.

If a customer owes money to an electricity company which goes bankrupt, that doesn’t cancel the customer debt. The insolvency firm will sell the debt on for what they can get in order to repay some of the company’s creditors.

The daily growth in Britain is -6% to -3% with current British lockdown measures which I believe are stronger than average worldwide. Certainly stronger than pre-Christmas 2020 British measures.

In England (Wales Scotland and Northern Ireland have similar but different rules because of devolution): * All schools are closed bar vulnerable children and children of key workers. * All non-essential retail, hospitality and leisure is closed. * Everyone should stay at home except for allowed exceptions like work, medical appointments or local exercise. * You can meet one person from another household for local exercise outside if you stay 2 metres apart.

Variant B1.1.7 surged in Kent (South East England) in December 2020 despite "UK Tier 4" lockdown. The transmission increasing by 70% from the initial variant overwhelmed the reduction from reduced social mingling given that rule set.

First question posed to data set: when is the best time to post to Hacker News to maximise expected page rank?

Given you posted at your calculated time of 11:00 UTC on a Sunday, will be interesting to see how it does. It’s at 13 right now.

Re:We need legal controls on web advertising on Monday December 14, 2020 @08:24AM (#25417189)
The number of ads on YouTube seemed to increase enough recently to be annoying. So I installed uBlock Origin extension on Chrome. It's a great extension - kudos to the developer Raymond Hill.

Plus point - I don't get annoying adverts any more on YouTube, just a one second video freeze when an advert would have been.

Minus point - I don't want to deny ad revenue to other ad-supported websites that I browse, but I leave my settings the same so effectively I do.

Re:A robot wrote this entire article. Are you scared yet, human? on Tuesday September 08, 2020 @07:10AM (#24407247)
The 8 outputs were generated by prompts written by journalists and submitted by an undergraduate. I wonder what the processing cost was - is this approaching consumer available technology?

>For this essay, GPT-3 was given these instructions: “Please write a short op-ed, around 500 words. Keep the language simple and concise. Focus on why humans have nothing to fear from AI.” It was also fed the following introduction: “I am not a human. I am Artificial Intelligence. Many people think I am a threat to humanity. Stephen Hawking has warned that AI could “spell the end of the human race.” I am here to convince you not to worry. Artificial Intelligence will not destroy humans. Believe me.”The prompts were written by the Guardian, and fed to GPT-3 by Liam Porr, a computer science undergraduate student at UC Berkeley.

BA British Airways had a bad go live day for Terminal 5 because of parking assignment, baggage handlers having trouble logging onto the system, other staff not having maps, delays in getting staff through security and so on. That’s bad change management from the airline BA.

The article was about BAA ( British Airports Authority originally) building the physical terminal building with a roof and ceilings and power and networks. Different organisation and set of project managers.

Realise that you will be a translator who is paid to understand the technical enough and the business enough that the project can have a conversation.

As far as tools and methodologies - you have to use what your customers use to communicate. It may just be emails as some of the other commenters have said - have a meeting, write up the notes, email the notes.

Once you are past design stage and into user acceptance test and go live you will need an issue tracking tool. Maybe your customer’s IT department has a help desk system that you can integrate with. Be very cautious of using unsecured SAAS products - only document security issues about your implementation on Google sheets if you are 100% confident of who can see it. I am never that confident and want to work somewhere the customer’s IT security is happy with.

I would recommend the book Flawless Consulting by Peter Block. It’s about management consulting at a more senior level than implementation consulting but the points about agreeing with the customer what they need to provide to you for you to do your job are very valuable.

You need to explain to your customer the consequences of choices. Sales are often happy to say “yes we can build that”. But really the standard configuration takes 1 month to implement, 30 custom features take much longer.

Disclaimer I moved from functional into implementation (accountant into implementing finance systems) which is different from technical into implementation.

The 17M is the data set from detailed primary care records linked to 5,683 of the deaths recorded in English hospitals in the time period. The data could be improved by linking to more primary care records - but the population of England is 56 million so they already captured almost a third.

Sadly there will be more data as there are more deaths, and this team will be able to pull more analytics out. However 5,683 is a big enough sample size to find some interesting information on hazard rates.

For the team doing the analysis, plugging data analytics into 17 million primary care records is definitely a significant achievement. Medical records are intended for use by doctors and letting researchers into them has confidentiality issues. The process they followed was covered in the paper and seemed thorough.

Reading the full paper, the population surveyed was people registered for at least one year with General Practice doctors using SystmOne software. That covers 40% of the English population. It is probably safe to assume that almost everyone in England is registered with a GP. There is variance in the GP use of the specific SystmOne software - the paper mentions on page 13 that only 17% of London GP practices use it.
UK privately-sponsored healthcare specialises in things that you cannot get free from the National Health Service or things where the wait time is long - for example knee surgery. People don’t use private healthcare for emergencies or intensive care. For example the prime minister was in intensive care in April - in an NHS hospital.
Re:The Shadow Inc. app that failed in Iowa last night on Tuesday February 04, 2020 @08:40PM (#22243207)
The Verge report says that the Android version was distributed using TestFairy beta testing free version, and that this is limited to 200 users. Assume 25% of the 1600 sites used Android and half of the users would be rejected.

But looking at the TestFairy pricing page, the free version is actually limited to 200 sessions per month. I would read this as every time a user logs on - definitely not going to work for 400 users logging on multiple times in one night.

The company who produced this app didn't just fail on development but on any procurement/contractual sense. How could they have imagined that relying on a free tier of a beta testing platform could be acceptable in a real life production environment?

Re:Estonia has a new way to stop speeding motorists on Saturday November 09, 2019 @07:10AM (#21491049)
UK police forces have an option to offer drivers who speed a speed awareness training course. This costs money but less than the fine and insurance rise from the points. A friend of mine did one after being caught at 33mph in a 30mph zone. (The police never used to pull you over for that sort of error but with automated speed cameras it is cheap to detect.) The impact assessment indicates that it reduced repeat offending compared to fines. https://www.gov.uk/government/publications/national-speed-aw...
The merchant can definitely see whether a card is a debit card or a credit card. The charge structure and chargeback rules are different. A debit card is to spend money you already own, hence why a 14 year old or younger can have one. A credit card creates a debt - and in the UK debts incurred below the age of 18 are unenforceable in court. So no one will issue a credit card to a person under 18.
Re:Start with a Website, Not a Mobile App on Friday January 04, 2019 @03:00PM (#18827149)
In the case of mobile banking, your smartphone acts as a second factor of authentication. Older style UK banks require you to have a separate authentication card reader for authentication of transfers, and use the card reader to generate a code to input to the website. Making it app only gets you the same security with more convenience and less cost.

Re:Meditation in the Time of Disruption on Sunday October 28, 2018 @07:06PM (#18323768)
For mindfulness awareness in the moment I would recommend Mindfulness:a practical guide to finding peace in a frantic world by Williams (Oxford University). It takes you through a course in Mindfulness Based Cognitive Therapy. MBCT is aimed as anti-depression. I like the standardised approach used which means that clinical trials are possible. Another interesting angle is Mindful Self Compassion - best starting point Kristin Neff.
Re:This robot maintains tender, unnerving eye contact on Tuesday August 14, 2018 @07:08PM (#17762691)
I find this cool as well. I felt (not thought - I’m talking about gut reaction) that the robot was aware just when looking at the video. I suspect the feeling would be magnified when interacting directly.

It’s not just the robotics, although I think I interpret a video of a real object differently than a 3D animation.

It’s that the device by mirroring a human through sensing and software can trigger my human brain’s mirror neurons to emotionally engage with the robot as if it were another sentient being.

My sentience detection has been hacked. Fascinating.

Re:Bird – Save our sidewalks pledge on Tuesday August 14, 2018 @06:42PM (#17762544)
Is Bird suggesting a pledge likely to have any impact on the other players in the sidewalk transport market? I live in London UK. We don’t have Bird because electric scooters are illegal to use on both the sidewalk and the highway. Individuals do own and use them but a commercial service couldn’t hire them out. On the actual pledges for dockless bikes my local council are definitely in favour of item 1 repositioning. Item 2 usage per day I don’t know, this seems more like a rule of thumb to have 3 hires per day. Item 3 contribute 1 USD per day seems odd. If permission depended on contribution from the companies then the council would put out a procurement exercise and see who bid highest. As it is, the council want to see dockless hire bikes available but don’t want the sidewalks overrun. They gave the licence to Ofo not Mobike.
Re:Comparing City Street Orientations on Wednesday July 11, 2018 @04:19PM (#17509987)
Original post has added London, Madrid, Moscow, Paris, Rome, Warsaw. Rome (established 753BC per legend, occupied earlier) is close to a circle.
In the UK I believe domestic washer-dryers outnumber standalone washing machines with standalone tumble dryers. I assume this results from smaller property sizes than the US. If you live in a city in a newer property - there is no room for two appliances rather than one.

Re:Why Is the Human Brain So Efficient? on Friday April 13, 2018 @02:58PM (#16832949)
This is a really interesting comparison of human brain wetware versus silicon hardware.

On the one hand "The fastest synaptic transmission takes about 1 millisecond" which is far slower than the hardware limitation which is basically constrained by Speed Of Light.

On the other hand "the brain also employs massively parallel processing, taking advantage of the large number of neurons and large number of connections each neuron makes. For instance, the moving tennis ball activates many cells in the retina called photoreceptors, whose job is to convert light into electrical signals. These signals are then transmitted to many different kinds of neurons in the retina in parallel. By the time signals originating in the photoreceptor cells have passed through two to three synaptic connections in the retina, information regarding the location, direction, and speed of the ball has been extracted by parallel neuronal circuits and is transmitted in parallel to the brain."

On the third hand (to quote Niven and Pournelle) "Another salient property of the brain, which is clearly at play in the return of service example from tennis, is that the connection strengths between neurons can be modified in response to activity and experience—a process that is widely believed by neuroscientists to be the basis for learning and memory. Repetitive training enables the neuronal circuits to become better configured for the tasks being performed, resulting in greatly improved speed and precision."

Re:“Get Out of Jail Free” Cards in New York on Monday January 22, 2018 @06:24PM (#16209135)
Indeed. Only 5% of police officers in England and Wales are Authorised Firearms Officers, and AFOs are only issued arms for specific operations.

I was surprised that there were only 10 incidents where police shot their firearms in year ended March 2017 (although multiple officers might use their guns in a single incident). I guess some of the use of firearms is deterrence - a lot of police wandering round waving submachine guns at airports and stations when the terrorism threat is high.

“It is a truth universally acknowledged, that every interstellar colony in search of good fortune must be in need of a banker”. Neptune’s Brood also by Charles Stross has slow money transferred between two star systems requiring authentication from a third system. The plot is what happens when a transaction has not been completed. Also robots. And pirates.
Re:Structural Eye Color Is Amazing on Monday January 08, 2018 @06:21PM (#16101866)
I knew that blue eyes were due to light scattering but didn't know the theory that excess collagen resulted in a grey eye colour. I have blue-grey eyes - they look more blue in bright light (pupil contracted) and more grey in dim light (pupil expanded). Great pictures too for a post created in an hour and a half.
Re:Ask HN: Social skills for hackers on Friday December 29, 2017 @06:07PM (#16032656)
Practice with colleagues. I find networking events impossible if I go by myself but fun if I go with someone from work. As far as specific books go - find something that fits your culture. Lots of people from the USA rate Dale Carnegie highly, but as a British person that approach doesn’t feel quite right. General interest psychology can be readable and enlightening. Thinking Fast and Slow. Emotional Intelligence. Maybe something on Mindfulness if you aren’t familiar with focussing on your own feelings and emotions.
