johbjo··on Americans Done with 5-Days a Week in Office: What That Means for the Economy
> The attraction of the city is its rich social life.

Ok, we agree then?

johbjo··on RFC-8905: The 'payto' URI Scheme for Payments (2020)
The OCR codes/checksums are readable both by machine and human, which was the point. Not a hack.

But the bit-length of the QR-code is probably bigger than what humans would accept so putting the information into alphanumerics might not be practical.

Young people want to work in cities for the same reason kids want to return to school after summer.

For so many, work is connect to lifestyle and meeting people.

Coordination is a bit euphemistic. Redistribution is probably a better term.

The owners of the burnt houses are not the beneficiaries of the growth during rebuilding. Likewise for guilds and institutions.

johbjo··on Elliptic Curve Cryptography Explained (2019)
As long as the points are not above/below each other, it will always intersect. We can see in one of the linked notes that vertical points are defined as each other's inverses, and adding them results in a type of "zero-element".
johbjo··on Had Covid? You’ll probably make antibodies for a lifetime
The linked article doesn't support either view.

The link reports that vaccines have been observed to generate higher antibody-levels than natural infections. It was also observed that vaccines seem to protect against a set of variants. This is the good news that is worth reporting.

But there are observed occurences of the opposite; that vaccinated people test negative for antibodies. Similarly, people test negative for antibodies some time after recovering. Sometimes, recovered people never test positive for antibodies.

Diagnostic tools widely available are simply not good enough to test the immune response.

> Telling people to have fewer children in an area where few children make it to adulthood ...

Are you arguing for more or fewer children?

Seems plainly obvious the birthrate is too high.

johbjo··on Klarna users are being signed in to random accounts
Yes?

The session layer should confirm and only accept that the other SSL-endpoint is an authenticated app. The app should do this as well.

If a toggle box exists that can cause this, I'd wonder how much of else of the implementation is worth saving.

johbjo··on Face masks effectively limit the probability of SARS-CoV-2 transmission
Also consider age distribution/population density in areas you compare.

Death rate is exponential in age, so small differences in age distribution gives big differences in relative deaths.

> What is astounding to a lot of us in South East Asia is the reluctance of the West in learning from our lessons.

Agreed. We should have relocated Britain and NYC to the equator long time ago.

> It needed to record and store information about individual particles in order to decide when to open and close the door.

This isn't true, all it needs is to store the average speed of particles on either side of the door and it would still converge.

johbjo··on Poor in Tech
I got: for her it's a job, for the rich it's a hobby and a pass time.
johbjo··on Umami – An alternative to Google Analytics
The value google provides here is not the technology, but a "neutral" external partner. It means that bosses do not need to elevate anyone's responsibilities to some niche (but probably better) alternative tool.

It's the same with most standard tools or outsourcing partners. The point is not so much "no one got fired for choosing IBM", it's that IBM is customer to the boss, not the subordinate.

A big value in SaaS is that it allows the boss to have the highest privileges in all systems.

johbjo··on Why Generation X will save the web
The "founders" were GenXers and older but the internet or "cyberspace" was so tiny then that there are as many clueless GenX now as from any other generation.
johbjo··on Crazy New Ideas
Another perspective; blogs and wikis are two use-cases of essentially the same interaction. The different designs guide and inspire people how to use them. Then, they discover that the use-cases are beneficial.

In some ways, all of social media consist of apps tailored to specific use-cases that haven't been new for decades, but they "invite" normal people to use them.

Citation for this would be helpful.

johbjo··on Reaching ‘Herd Immunity’ from Covid Is Unlikely in the U.S., Experts Now Believe
> lost all faith in public and academic institutions

The people wearing masks outside, what are they afraid of and where are they placing their faith?

johbjo··on Market is the most important factor in a startup's success or failure (2007)
Not really. Early/immature tech causes early movers to overspend and be invested in the wrong things. Early, usually the tech is expensive so it's perceived to be valuable on its own. Later, when the tech has diffused and is ubiquitous, it's clear that various secondary things create the actual value.

Successful early movers realize how the value-creation is going to happen once the tech is mature, and focus on that.

johbjo··on CEOs are hugely expensive – why not automate them?
One aspect of leadership is symbolic. If the company falls on hard times and needs to restructure/fire people, we can let the current CEO be associated with all the ugly stuff, and then bring in a new CEO to raise hope.

There is a need for the employees to believe the CEO is important. Pay is one dimension in which this can be accomplished.

CEO pay functions as an aspirational goal for all career paths in the company.

I think the actual role of CEOs is symbolic, in these and many other ways.

johbjo··on Paid in Full: an internet where every interaction is a financial transaction
Content creators are not the beneficiaries of the current copyright legislation, which enables accumulation of large catalogues of old works that can be used to strong-arm central platforms to act as gatekeepers (for lack of a better word.)

Living independently from patreon and youtube is the dream of most content creators. Whether it is currently viable isn't an argument in favour of current copyright legislation.

Just have a part of the article+ads visible on a news site, then show the rest without ads after a click on 'see the rest for $0.01'.
johbjo··on Paid in Full: an internet where every interaction is a financial transaction
No. The reason d'etre for the centralised platforms is that they are accountable to the major rights holding companies. That's all. One can speculate why this is so important for society, but ostensibly it is to protect the rights of Universal, Disney, etc.

Accountability becomes impossible with decentralization, and small decentralized distributors can be easily intimidated with copyright-related legislation. This is partly why p2p fizzled.

Internet change will require political change, such as rolling back various copyright legislation. For example, limiting to 20 years (like patents) and several others. The consequences of this would be to erase the book-value of the rights holding companies.

But decentralized media can not be held accountable to society/politics like for example Youtube. I suspect this is the underlying political motivation, not so much charity to Disney.

johbjo··on Previous Covid-19 may cut risk of reinfection 84%
There seems to be the intention to lower incentives to be infected, and to raise incentives to get vaccinated.

Therefore, the party line seems to be to dismiss natural immunity.

I think the talking points will change once all 50+ people in the west are vaccinated.

johbjo··on Previous Covid-19 may cut risk of reinfection 84%
Antibody tests are designed to have low false positives, not low false negatives.

And blood samples have found that a proportion of samples have t-cell immune responses to sars-cov-2 without antibodies, possibly with no exposure to sars-cov-2 specifically.

Specific antibody levels drop after a few months.

Therefore, might be impossible to establish if someone was exposed or what level of immunity.

johbjo··on Just Be Rich
There are different mechanisms involved. Wealth inequality in general is caused by cheap credit which drives up asset prices.

Facebook and Google are not tech companies. The own all the best advertising real-estate.

Amazon owns all the best store-front real-estate.

And so on. There is no limit to how much of the relevant real-estate these can companies can own. Therefore exponential distribution of valuations.

"Tech" is not a big part of it. For example, there is no way of competing with these companies based on tech.

Hm. What about taxation of domain names based on revenue?

> This becomes the limiting factor almost everywhere, meaning that prices would be equally unaffordable if credit wasn’t cheap.

The point is that cheap credit (mortgage regulation) significantly raises the upper bound on this limit.

johbjo··on Economy is on the cusp of a major boom and economists believe it could last
> last great booms we saw in the States

The exact same booms were seen all over the world. It's probably due to innovation and sharply falling energy prices (oil, hydro and nuclear.)

A boom the 90s is probably attributed to IT-productivity, but mostly sharply falling labour prices due to Chinese manufacturing.

Overall, booms are probably due to falling prices in input factors. Subsidies alone just leads to increasing prices.

Next boom probably happens when AI can replace menial jobs.

johbjo··on Don’t hire top talent; hire for weaknesses
> “We hire top talent”

These phrases are mainly intended to flatter the employees, to make them grateful for being "chosen", and maybe to increase trust and confidence among them.

Choosing who to hire (once basic requirements are met), is much less important than the morale and attitudes among employees. Much better to say "top talent" than "randomly picked".

But, the hiring process is a huge factor in the perception of the identity of the employees.
