nopassrecover··on Stages, Structures, and the Work of Being Yourself
While he’s far from my favourite philosopher, there’s a similarity between this article and Sartre’s discussion of Bad Faith (itself similar to Marx’s alienation) as both discuss the societal pressure to conform to roles and the conflict inherent in attempting to do so.

As the article observes, the liberty of expression offered by social media may itself compromise our individuality and authenticity by pressuring us to stage-manage an image of ourselves compatible with societal norms: an image that we aspire to but can never fully realise.

nopassrecover··on Ask HN: Why is there no activity indicator when an iPhone's camera is on?
This might be specific to the MacBook Air but it seems trivial on the Mac to capture without an LED. E.g. open up Skype and go to settings and you’ll see live footage of your camera without the LED coming on. Am I overlooking something?

nopassrecover··on Approaching the kernel year-2038 end game
I’d always assumed they must be connected to support the ability of fire engines to setup route plans or the central traffic management teams to be able to override light sequences.

I see now there are other novel ways of supporting preemption for emergency vehicles, although I’m still unconvinced that’s what our city uses as the lights often preempt several minutes in advance and from over a kilometre away.

nopassrecover··on Did Thomas Kuhn Kill Truth? A review of Errol Morris's critique
Great article!

Tangential, but the author’s description of Kuhn’s paradigms as describing things incommensurably differently (“claims that were true in the old way of talking might be false in the new way, and vice versa”) reminds me of the way Hofstadter summarises Gödel’s incompleteness thereoms in GEB. That is that no set of axioms can be both mathematically complete and consistent, so we may need multiple theories (paradigms?) to reason effectively and discover all truths.

Morris seems to claim (based on the author’s summary) that necessary a posteriori truths (ala Kripke) provide some sort of anchor across these paradigms that proves newer paradigms are better than older ones because (and I’m a little unsure on his argument) newer theories are still describing the same thing in different detail and we can therefore see that a newer paradigm is objectively richer and more truthful.

However, I wonder as Kuhn did whether this argument is strong enough to handle all scenarios. As Kuhn argued, a concept of Heat is substantially different across paradigms. I would add to the list those qualitative problems like consciousness and qualia that seem, at least at this stage, to require non-scientific paradigms (ala Lyotard) to reason meaningfully about, but in taking on these paradigms we lose the ability, as Kuhn argued, to talk meaningfully about things we could previously.

nopassrecover··on Carlo Rovelli on challenging our common-sense notion of time
One difference of course is that while we can always return to a physical position in space, even if the contents of that space have changed, it seems very conceptually challenging to imagine returning to a position in time even if the contents of that time had changed. What would this even mean?

Our definition of time seems therefore to be two things: first, a snapshot of physical state (in which we imagine points in time a bit like Back to the Future), and secondly (as other comments have noted) a measure of periodicity.

The latter is that which we seem to be measuring experimentally (e.g. with differences in atomic clocks within gravitational fields). However what we are literally measuring seems to be something like “how many times can a given particle move/irradiate relative to another given particle before we bring them back to each other”. Reducing to a pendulum for example, we could imagine that the space was “more dense” so it took longer to travel the same apparent distance, a bit like how light takes longer to travel through particular materials. Another way to see this would be a kind of universal framerate.

So based on this possibly weak conceptual understanding, I can certainly imagine a fourth property of any given spacetime location that reflects how frequently events can occur in that space (a kind of EM-field view of time), but to consider this as a geometric “position” or coordinate is something I conceptually struggle to imagine.

nopassrecover··on The Children of Anaxagoras: Did hands make us human?
Perhaps a tangent, but the article opens with a claim that the Indonesian rock art is conclusively the oldest art of Homo sapiens, but strangely overlooks the art of Indigenous Australians which is at least as old, and perhaps a further 10,000 years older.
nopassrecover··on America is losing the battle against robocalls
I appreciate the US has 10x the population, but Australia’s Do Not Call Register (https://www.donotcall.gov.au) has been fairly effective at reducing these calls (with a domestic origin at least).

It works as a central government register with a threat and imposition of large penalties for companies who disregard it.

nopassrecover··on Fake books sold on Amazon could be used for money laundering
I’ve always wondered the point of this. I had a card stolen (skimmed in a taxi) and the first thing they did was donate $1 to a charity, before buying $12k of aquarium equipment from another country. Why not start with the aquarium purchase? (side note, the bank didn’t chargeback the donation because it would have cost the charity, and I wasn’t going to challenge that).
nopassrecover··on Childhood intelligence in relation to major causes of death in 68 year follow-up
Or intelligent people may be more likely to apply cognitive techniques (perhaps they experience depression earlier and/or more commonly which may build resilience) and/or may be more likely to seek professional advice (e.g. because they see the value, move in circles in which it is more acceptable, or make more money and can afford to).
nopassrecover··on How Australian Tech Companies Can Think About Silicon Valley
Great analogy and completely agree that we couldn't compete on overall opportunities. Would still argue we have a pretty unbeatable lifestyle though, which it sounds like you're pretty familiar with :-)

As far as recruiters, I can't recall a week here without at least one contact, but it sounds like it's even busier in NYC!

nopassrecover··on How Australian Tech Companies Can Think About Silicon Valley
I can agree there are more opportunities elsewhere, but ive never met a developer or similar in Aus struggling to do well, and have generally found US devs shocked by our salaries and living costs.

On the other hand, if you want career advancement there's something pretty cool to the US idea of "have managed 15 people after 2 years experience" which just doesn't happen here in Aus.

nopassrecover··on How Australian Tech Companies Can Think About Silicon Valley
Depends on your skills of course, but most dev jobs on seek / I run into and hire for are paying quite a bit more than that, particularly contract. When the AUD was stronger than USD this was an even more compelling argument.

However I acknowledge the opportunities of equity returns are far higher in the states.

The liveability of places like Adelaide (and even Melbourne, Sydney, Brisbane, and Perth) is such an undersold secret. Personally I'm so torn between wanting to tell everyone how good we have it and wanting to keep it to ourselves.

Melbourne, Adelaide, and Perth are all in the top 10 cities to live in the world.

Taking Adelaide for example (1.2 million people), we can live within 10-15 minutes of the CBD in a roomy townhouse for highly-affordable rent, get paid pretty well, be 20 minutes from the beach, 20-60 minutes from four different world-class wine regions, have a great festival culture, delicious local food and wine, and a highly safe and welcoming culture.

If you want a larger city you have Melbourne (3.9 million) with a fantastic bar and food culture and endless high-paying work.

As a company, and this is somewhat anecdotal, you have high availability of highly-educated workers who are used to working collaboratively and doing whatever's needed to get things done to cover the work of N other people (low population after all).

Depends where you live. Fresh food from an independent grocer is noticeably cheaper, fresher, longer-lasting, and tastier than any of the food (packaged or fresh) from major supermarkets here in Australia.
nopassrecover··on Ask HN: What's your worst Uber Eats/Door dash experience?
UberEats decided that I lived in the very center (i.e. GPS lookup) of my city for a booking despite numerous bookings before and after. This meant I had to drive in, park, and meet up with my my poor UberEats delivery driver who was on a bike and had no chance of making it to my place anytime soon.

UberEats drivers who accept delivery of multiple orders, so you wait for everyone else's orders to be cooked and delivered before your cold burger and fries arrive. This problem is exaggerated by either these orders being on opposite sides of the city or the delivery driver being on a bike (why either of these are permitted I have no idea). Have even had my order delivered to someone else and vice versa this way before.

In general, slow deliveries and the usual process of having to walk up the street to find lost/lazy drivers. The ETA always being wildly wrong (I get cooking delays, but delivery ETA from pickup should be spot on, and is usually off by 100%). Then add in general restaurant problems with mixing up orders, missing items, or selling food that doesn't transport.

Would happily pay $10 (maybe even $15) per delivery rather than the $5 they charge now if all of these problems went away (e.g. guaranteed prompt and direct delivery).

nopassrecover··on Wall Street Banks Warn Downturn Is Coming
Our (Australian) government at the time provided significant consumer stimulus (most taxpayers got up to $950 to spend, people on welfare and/or with children got even more) and it also invested heavily in infrastructure and construction projects (http://www.smh.com.au/articles/2009/02/04/1233423265116.html). Like other countries, our central bank also dropped interest rates.

As a consequence we now, apparently, lay claim to the longest period of uninterrupted growth in modern history.

However, we've had uncharacteristicaly flat growth since, narrowly avoided recession a couple of times, and are battling low wage growth which, in combination with rising energy and property costs, is beginning to undermine consumer demand.

This has been unhelped by the end of a mining boom, related decrease in Chinese growth and demand for commodities, structural taxation challenges (income taxes were reduced during the boom, and we struggle to tax multinational companies), and a huge speculative property bubble (fuelled by lower interest rates, favourable taxation schemes, currency flight from foreign investors, and ultimately the self-reinforcing returns). I'm sure demographics are playing a role too.

Considering most of our pension schemes ("superannuation") are invested in either property, mining, or banking (itself dependent on property), there's huge uncertainty ahead.

nopassrecover··on Sperm Count in Western Men Has Dropped Over 50 Percent Since 1973, Paper Finds
Economic changes can probably be tracked back to Stagflation[1] and the 1973 Oil Crisis[2], and the associated rise of Neoliberalism as evidenced, early on, through the Nixon Crisis[3] and formation of the Trilateral Commission[4]. Of course there was a huge amount of social change going on at the same time, much of which was interrelated with the economic changes.

As an example of how some viewed these challenges, the Trilateral Commission's 'Crisis of Democracy' paper[5] - though heavily criticised from both sides of politics[6] - offers some interesting insight into the perspectives held by a number of highly influential people of the period.

nopassrecover··on Scientists made people turn off notifications for day, saw an effect years later
I've recently taken to turning off all sounds, including vibration. I still get notifications, but they're reviewed on my terms.

Yes I miss a few calls, but there's rarely anything that can't be followed up with (I put my phone on vibrate if I'm expecting an important call), and the peace of mind it brings (and reduced flow interruption) has been fantastic.

nopassrecover··on Inbox Zero for Life
This is just for personal mailboxes, where signal to noise ratio is very low.

Priority Inbox highlights anything that actually comes from a human.

Multiple emails are more effective (for me) for automated and marketing emails, e.g. "right, I should remember to buy some more shirts from that company that keeps sending me offers", or "that domain is expiring soon, I noted that it was 30 days out last email but now it's getting closer".

Given the importance/actionability of these kinds of emails roughly approximates status updates on Facebook's News Feed, my approach has been similar (browse, trust that my eye will catch anything important, don't waste effort trying to read through every single piece of information).

You're right that I could make an effort to read through each email I receive immediately and decide whether its actionable, but this approach works well for me with very little effort.

nopassrecover··on Inbox Zero for Life
> After a few weeks doing this stuff I didn’t just get there, I’ve stayed at inbox zero virtually the entire time

Would be interested to see how he's going 4+ years later.

At least for personal mailboxes I've found 'inbox zero' a thankless task and have settled for "inbox as a feed" in which I trust that anything important will catch my attention (e.g. via Priority Inbox or multiple emails) and everything else will fade away. For what it's worth, this means I currently have 12k+ emails that I'll never open.

nopassrecover··on Uber Driver Tip-Hustling Schemes
In Australia we've tried tipping Uber drivers (e.g. because we've inconvenienced them with a stop to pickup food on the way home) and so far after 5 occasions no driver has accepted the tip (taxi drivers accept a tip without question, and usually won't accommodate short trips, despite the law, yet alone special requests).
nopassrecover··on Ask HN: Hourly freelancers, what do you do when you can't figure something out?
Agree for time spent learning new frameworks and technologies (i.e. generalist self-improvement that will be applicable to many clients and is part of your advertised skill-sets), but I would disagree on the example you've given (encountering an obscure bug during development).

Isn't this kind of learning really a discovery process inherent to analysis and development?

To take an old anecdote of the engineer who charges $1 for making a chalk mark and $9999 for knowing where to make the mark - if you're going "off the clock" while you work out where to make the mark (i.e. debugging a library), are you then charging higher rates when you "know where to make the mark"?
