30mph changing to 20mph makes a huge difference to journey time... And london drivers hate it to the point most of them ignore it.

Doesn't work on mobile :(

In the UK, I've helped run some of the ninja bookshop crawls. There are usually guided routes that take you through independent bookshops - they are always interesting and great for discovering bookshops and the cities themselves.

Independent and second hand shops have really benefitted from these events and they usually offer discounts and gift bags for crawlers

what is stopping you from buying and reading books on cryptography, number theory, security protocols etc?

why couldn't you? of course you can

This is just the age old question of nominalism vs realism

I have worked in transport for over 5 years in software and have read most of the technical books in the internal London Underground library. I generally have read >50 technical books a year.

In my blog I collect and distill what I have learnt. I write about transport, software development and things I feel others should know.

If you try driving in Italy like you do in the UK, people will use their horn. Then you will understand.

That's what organisational transformations are for

Not true at all. If you have tech skills, you will never run out of job opportunities in the UK

have some compassion and screw the rules

Britain runs 20% of Europe's rail journeys. It has the least accidents and deaths of passengers and staff. It is considered the most improved rail network year on year since 1997. It has some of the lowest fares if you book far in advance (and count the cost of subsidisation for foreign fares).

I work for Transport for London and I advise people to use citymapper rather than the official TfL tools.

An alternative take here: https://www.michalpaszkiewicz.co.uk/blog/reviewnapocs/index....

While more infrastructure will indeed just create new wardrop equilibriums (and potentially sometimes make things worse - see Braess' paradox), banning cars is also a bad idea.

Frankly, cars are the most efficient means for individuals to travel - they may result in poor traffic flow on some single links, but otherwise they have huge benefits.

It is also worth noting that banning cars will affect the poor the most negatively. While poor people use cars less as a percentage of their population (about 9/10 the percentage of the amount that the rich use them), there are far more of them. Poor people are often the ones who have to manage multiple cases - a family and a job, a few jobs etc and often are unable to love near their workplace, or to find a (decent) job near their suburban homes. All of this means that the value of a car is much higher for them, as it can be the means for them to manage their more complex life scenarios efficiently (see "Disrupting Mobility" for more details - it's a great book)

WebAssembly?

I wrote a post that explains this as well, including a playable game with cards (uses js) https://www.michalpaszkiewicz.co.uk/blog/montyhallexplained/...

1. Has no support from central london residents and

2. Sadiq Khan has already tried to Pedestrianise Oxford Street, but was blocked by parliament.

3. There are cycle lanes and cycle highways and there is a lot of development in the cycle space - and will no doubt be continued. Bus lanes and schemes to improve buses are constantly being tried, but their uptake is low, meaning that it is difficult to increase the service, as they are not very profitable

They certainly get different results - but as I said, I don't know the intricacies of their system

Agreed - I've had similar issues when renting a big van - I was directed through streets where I didn't comply with width restrictions

I don't know what happens under their hood, but I know for sure they source some data from third parties. Makes sense to, considering TfL provides a lot of data - e.g. live bus times etc

Transport for London Tech Lead here.

In London, we have been collaborating with google waze - we provide them with information at the local level. Streets that waze should not use for route finding (e.g. roads with schools) can be blocked for use by Waze. Both local councils and TfL can provide this data.

The main difference between Waze and Google Maps is that Waze uses real time traffic data. There are multiple map providers that do this in London. There is a plan to provide different data to different TfL data consumers in the future to try and get map providers to seperate traffic across roads (at the cost of surrendering absolute truth).

London is also host to discussions of taxing roads - this is unsurprising when the roads are mostly paid for by the cost of the London Underground (LU makes the majority of public transport money, but 80% of revenue goes into road, traffic and bus management). The London Assembly (who supposedly keep the London mayor accountable) have written a paper "London Stalling" to suggest road taxing related to mileage across London. This, they no doubt expect, will cut down the traffic. However, from my understanding of embellished models of Braess' paradox, this will only result in similar traffic (on maybe slightly different roads) with an optimum equilibrium between how good a route is and what the cost of it is - meaning people may just take longer to commute and pay more tax.

For Polish speakers, I highly recommend this book:

https://www.ccpress.pl/produkt/Dowody_ontologiczne._W_900._r...

It has multiple formalisations of both Anselm's and Gaunilo's arguments, and critiques of each approach

For those who enjoy Wittgenstein, I highly recommend the works of one his greatest students - Elizabeth Anscombe. Possibly one of the most prominent women philosophers of all time.

wikipedia says - https://en.m.wikipedia.org/wiki/Blockchain - that transaction data is generally represented by a merkle tree in block chains

Don't Merkle trees underpin bitcoin? Why does it disqualify it as a blockchain?

this isn't entirely true. At the time of Galileo, Tycho was presenting his model (and was a militant enemy of Galileo). Tycho's model was either used or not depending on more local scientific stances, but it wasn't entirely popular.

no, Copernicus was never excommunicated, although "On the Revolutions of Heavenly bodies" went through various stages of requiring errata pointing out it was only a hypothesis and even a ban

I think he is using bird's-eye view distances, as opposed to bus travel distances. Roads are rarely directly straight between stops in London
