>So we are left with something people like and don't want to give up, and that's bad because... :)

Sorry, I should have taken the time to elaborate.

There’s certainly a conceivable scenario when the situation is either unsustainable or not providing a net benefit.

For the first case, consider a petrostate whose population is heavily subsidized by its oil sales. If oil price drops, whether by lack of demand or over supply, they may not have the funds to continue these benefits without debt, regardless if the populace “likes” them.

In the second scenario, it’s possible that it creates unintended consequences (like spikes in drug use, drop in life expectancy, reduced productivity) that become a larger social ill than what it was trying to prevent. Despite society being worse off, it becomes hard to scale it back because of the psychological endowment effect.

I’m not saying its likely, just as a counter point that just because people like a benefit it means it should continue. I think it’s important to do a “pre-mortem“ on these kinds of policies to make sure we have the guardrails in place before implementing them.
These are the studies I'm talking about. And we are talking about minor influxes of outside gene flow from the Arab invasion and slave trade. But the bulk of the ancestors of modern Egyptian are ancient Egyptians.
Making sense of data and sharing impactful stories
These results seem selective and flawed to me.

For one, the videos keep stopping and pointing out trees/greenery on the "desired" path, but ignore trees on the "fastest" path.

Also, the route along Marlborough Street shows walking on a street versus walking down an alleyway. The "detour" is a half block on either side of the route. I live in Boston and wouldn't even consider those alleys to be streets - they only exist for garbage trucks and parking for the people who live in those buildings.
I used to think that the best presentations are those where the slides are text only and the speaker just reads the text out aloud.

Just repeating the text of the slides verbatim

Because then I can download the slides at home, read them for myself, and do not miss anything. If the speaker would say anything important that is not written on the slides, I would actually have to go to the presentation, and am annoyed when they talk too slowly and angry that I cannot stay home.

Although my perspective is changing. Now I have glasses and cannot read as fast as I used to. And nowadays there are HD video recordings. With a video recording it does not matter how the presentation is done. In any case I could stay home and watch the recording at 2x speed

The same happens in a pure hydrogen atmosphere? Not sure what you are trying to convey here.
Thinking about this more, I wonder if you can predict whether a software project is "failing" by the amount of code that is getting deleted early on.

I've been part of a half dozen or so successful medium->large scale projects, and we never really deleted large parts of the code base. The small teams bootstrapping them had a pretty clear goals of where they were going sufficiently to build a reasonable scafold early on to get somewhat working prototypes. Then as the project took shape things were fleshed or refactored far more than they were thrown away.

OTOH, projects i've seen fail frequently had core pieces rewritten on a somewhat regular basis.

Which if you think about it in the sense that every time a chunk of code is wholesale replaced, that is X man hours of effort flushed down the toilet. Few startups can afford engineers to be working on things which don't go towards the bottom line.

AKA if you have 6 engineers, and on average are replacing 25% of the code base a year, that is the equivalent of just throwing away 25+% of your runway every year. With the team communications overhead/etc I could totally see that it might be possible to never actually make forward progress even though the amount of code being thrown away isn't >50%
It's not technically feasible because feasibility requires it to satisfy the common use cases. Being irreversible makes many use cases infeasible.

I see your point - Bitcoin does exactly what it claims to do - but it is not a feasible replacement for money.
Isn't it a more convincing argument than someone just commenting "it's not translating well". I see Teslas on the street every day. I've driven a Tesla. The next car I buy is going to be a Tesla.

I don't know if the market evaluation is right or wrong but Musk is clearly making cars that many people like. Hard for me to see how that is a bad translation.

I read it as a lament that our economies are so vulnerable to the actions of a relatively small number of large corporations. Including the idea of certain entities purportedly being 'too big to fail'.

Not sure if that was the intended connotation though.
> I spent some time last century living in Toronto, a moderately large North American city. The main street of the neighbourhood in which I lived was a former streetcar route crowded with small human-scale shops on the north side, and a church with a parking lot and some large office blocks on the south side. The north side was always crowded, the south side was always empty. It was obvious where people preferred to walk.

I'm in Sydney, AU - I've never been to Toronto, and know only that it's much further from the equator than Sydney is. Even in the mild climate of Sydney, I've noticed myself and others favouring the south sides of streets in winter here, simply because it receives more natural light & warmth.

For any given street, there's probably a handful of other candidate explanations for one side of a street being more favoured. It may well be an abundance of shops - if I want to amble, that would (all other factors aside) rate it higher. If I wanted to get somewhere, then I'd eschew a store-dense route, to avoid the myriad amblers that would slow me down.
You fell for the marketing. Billionaires were on both sides. The bulk of the damage is done to uneducated vulnerable retail investors.

So now you're out $1000. You contributed to a scheme which ironically was a net loss for retail. If this were really not about making a profit, you'd see people donating their gains or buying shares for other people, and nobody would be cashing out. Are you still in the trade? What are you going to do with your gain/loss?
Glad you recognize this fact. Love explaining the SPY as "rank public equities by revenue, take the top 500, then weight by market capitalization".

Starting an ETF is highly regulated, this differs in that these algorithms just manage your money interfacing with the public market rather than moving in ETF. Less regulation, but encounters tax implications (hence the less frequent trading of these models) among other things.

That seemed to have happened even though the code wasn't available. So yes, you are absolutely correct, people will lie, willfully or ignorantly.
I think this is right. In my boredom, I have studied ants and my observation was that they seem to send a small number of ants in multiple directions, carving a room up into sections. If an ant finds something of value, they change their pheromone to something that attracts the other ants. With time, they all eventually lock onto that pheromone trail, especially if it involves food. On a side note, they especially like vodka and I suspect they are disallowed from drinking it, as the bigger ants come along and chop off their heads. I was taken aback and never gave them alcohol again. Anyway, it seems this behavior is how they manage to find food and then transport it back to their nest. If you get this pheromone on your hands, the ants will swarm you and run around in different directions very chaotically. It seems to be a chemical based form of group think. Perhaps their intelligence should be measured as a group.

> One thing they didn’t mention is energy used for round trip per unit of H2 and cost of the material itself.

I also did not see anything about recycling the carrier materials which seems suspiciously odd in a context so closely related to environmentalism.

But the big picture news is that this is another datapoint that shows how, like you said, the solution space for what I like to call "bound hydrogen" is apparently not exhausted at all yet. In recent months I have seen (all on hn) power-to-ammonia, that Dutch group that proposes iron powder as a heat fuel of roughly coal performance that is recycled by reducing the returned iron oxide powder with hydrogen (and started to fuel a brewery as a pilot) and now this "powerpaste" which sound like straight out of the back to the future future. The claimed energy density is absolutely amazing! If the required infrastructure hardware is small enough it could be a gamechanger for BEV: size the battery to be sufficient for 80% of driving days and install the "1000 miles extra" block where it can be accessed for replacing, e.g. where an ICE car would have it's engine. Chances are the extra miles fuel won't be cheap, but you'll surely be able to buy a lot of RX refills for the battery cost saved if a strong majority majority of your driving can be done on battery only.

I always considered the term "hydrogen economy" silly because of how annoying H2 is to deal with at scale, but "bound hydrogen" can change that in so many ways. It's almost as if hindsight was trying to win a bet or something wrt how we look back at George W. Bush, first him appearing so unexpectedly presidential compared to a certain successor, then suddenly hydrogen economy ceases to be a joke. What's next, discovery of actual WMD so they could have well stayed honest had they just looked a little harder? Harris becoming president after "pretzel incident 2"? Bound hydrogen is the most exciting technology field since many years.
I disagree. We do have more “free-time” but what we decide to fill it with is not what I’d call leisure. What we think of as leisure today is not leisurely in any way. We browse on reddit, watch netflix, listen to spotify. And if we “take a break”, we’re just anxiously awaiting the next bit of entertainment. Leisure is walking slow and going nowhere, laying on the bed and letting the mind wander. True leisure is rare and should be refreshing and comforting, but when was the last time it felt like that?
These results conform to my bias, but seem to be based on the same flawed epidemiological data, based largely on seriously flawed NHANES Food Frequency Questionnaires, without the power to make causal associations. If I discount these studies when they tell me eggs will harden my arteries I should do the same when they tell me they don't, which I happen to agree with.

Tesla is not the only EV car on the market anymore.

The top selling EV in Europe in 2020 was the Renault Zoe, Volkswagen is catching up fast (they sold 56k ID 3 despite only going on sale in the second half of last year VS 85k Model 3 over 12 months), Tesla model 3 was second, but numbers are dropping.

If we are talking about quality, I think the new BMW and Mercedes will take the lead in the segment Tesla is being marketed right now.

Tesla numbers are good thanks to Norway buying a lot of them.

This is certainly true. I know Godwin's law, but there are some good books and stories (not sure if translated to English), of the children of SS officers, concentration camp guards etc.. They started asking questions of their parents when they got older (or sometimes only after their father died) and found out that the loving and caring father had been a monster at some point.

I've never been a fan of any review tool I've used because they all assume the code changed stands in isolation. Just today I was in a review where a change on line 234 was correct, except that it violated a bad assumption on line 123 which needed to be fixed. Line 123 is where I wanted to comment because that is where the problem should be fixed, but the tool saw that as okay code and didn't even let me see it, much less comment one it. It gets worse when the bad assumption is in a different file.

And I often get frustrated because I see you call foo(), but I need to see how foo works with the given arguments.

Though to be honest, most of the time I catch my self playing grammar checker, if the style isn't violated and you didn't make any of the dozens of checklist items you pass (I work in C++, so I often catch people writing c++98 code when there is a c++14 construct that is better)
I imagined when reading "tall high rise" that you were in DG&E. I'm not sure where you were at or if you are looking for something else, but we've long been in "Fortrust", now "Iron Mountain" which is north of downtown. In the past they've been very easy to work with, including at one point I used to have a dark fiber that ran from one of my cabinets to DG&E's meet me, where we used it to connect to Level-3. I know some of their customers have antennas on the outside of the building, though I don't believe I'm supposed to know why so I won't go into details. :-) They have plenty of parking, might be worth investigating.

DG&E is a weird and wonderful building. Used to have a client that had a suite in there. For those unaware, it is an old, old building, right next to the building that houses the Denver main telco switch. It was built over a hundred years ago, and has been Denver's largest (? maybe that info is out of date) meet-me room for Internet providers. Being such an old building, you can imagine it has all sorts of problems retrofitting modern requirements for cabling and power generation/backup.
The trophy case is here: https://www.cs.utah.edu/~regehr/souper/

Example program 6: https://www.cs.utah.edu/~regehr/souper/output_6.html

int a, b;
void fn1() { b = a * ~1 == 1; }

Here we multiply an int by -2. LLVM emitted the multiply and compare, but Souper proved that no int multiplied by -2 can equal 1, so this could be optimized to 0.

By its nature Souper becomes less effective over time as its findings are incorporated into LLVM, so most of the trophies are old!

> J can actually be parsed

Don't know where you got that one. J source can't even be tokenized except during execution!

NB. Compute n from reading a file of something
n : 0
Is this the source of a function, or a string?

Besides that, J has the same contextful issues as APL with regards to the value of variables determining how the syntax fits together. It's missing a few dark corners like niladic functions, but these are small differences; it's still fundamentally unparseable.

That is not my understanding at all, as that would imply we never have med school admissions without a residency slot, and I have seen many mentions over the years about how the great bottleneck is not med school admissions, but residency slots.

https://www.fiercehealthcare.com/practices/more-medical-stud...

https://health.wusf.usf.edu/npr-health/2019-07-03/american-m...

The above sources indicate residency matching is decoupled from graduation from Med school, and if I recall correctly, there is actually a legal cap on the number of residency slots.

https://www.aha.org/news/headline/2019-03-14-bill-add-15000-...

So everything I've seen suggests we actually have a dysfunctional system with no up front brakes. Our Medical education system maximizes fiscal extraction from hopefuls, but the residency slots don't scale elastically or in any way matched with demand. Quite literally, it seems to take an act of Congress to change the calculus of residency slots.

I could still be wrong, and welcome the removal of the veil of mistaken impressions, but that's the gist of my current understanding.
Hi Nerves! thanks for looking into it. Yes, I definitely understand what you said. I am working to make the demo available ASAP. Feel free to drop your email in the site's form if you want to hear about it as soon as it's out.
One could, but automatic differentiation is much more efficient than numerical differentiation, thus for high performance applications it is preferable to use automatic differentiation.
> 6,000 vs 30 is a meaningless metric

Even if you think that, the metric of only a single american merger ever being prevented, and it happening 20 years ago, is still pretty relevant.

If the regulators in Europe have only blocked a single merger in America, ever, then European regulators are simply not relevant to the conversation, and you have already conceded that American regulators aren't doing much.

You cannot handwave away the true fact that the EU has only stopped a single American merger, one time, 20 years ago. And that this is pretty good evidence that European regulators are not doing much to prevent American mergers.

> T-Mobile just acquired Sprint

Huh. And I guess European regulators didn't do anything about that, did they? In the clear and obvious cases of geographic network effects in the industry of Telecom, which I have already stated is one of the few exceptions where regulation is definitely needed (Telecom, has huge geographic network effects. It is the same problem as internet, or electricity, or water pipes, and I have already said that network effects are the one major area that consolidation will definitely happen), we see that European regulators didn't stop such a clear an obvious thing that should have been stopped.

> 6,000 small companies merging

Well, in one of the cases of large telecoms companies, such as t-mobile/sprint we see that it wasn't blocked!

> so they'll try and suss out whether regulators would be amenable to a merger before making it public.

Well they didn't stop the clear and obvious example that you just brought up regarindg T-Mobile/sprint. Looks like European regulators are doing much of anything.

So no, European regulators are not doing much of anything at all, to prevent American companies from merging, using an example that you brought up.

> Well, they tried in the early 2010s and the DOJ filed suit is why

As I said, before, businesses that have huge geographic network effects are one of the few exceptions where there is a huge advantage to consolidation. But even IN these clear and extremely obvious cases, only sometimes will regulators take action. But sometimes they won't either.

The fact that nobody blocked the t-mobile/sprint situation is clear evidence that regulators aren't doing much to stop mergers, even in the rare and obvious cases where they should step in.
I think that's the key what lesson(s) did you learn. No point in worry about something you can't change.
If someone had enough money, would it be possible to buy a controlling share in NewsCorp?
I agree. I’ve actually been working on something along these lines[0], albeit with a focus on marketing analytics. In my experience everyone in marketing cares about dashboards and metrics a lot but outside of larger shops almost no-one is doing any real analysis and even simple tools like linear regression could have a big impact.

Early days but we’re looking to onboard a few more customers to help guide our roadmap.

>I mean, this basically is my experience with contractors, auto mechanics and most other professions where there's a lot of information asymmetry between consumers and providers.

The unique feature of the medical care system that's different from most other professions is that there's multi-way asymmetry.

An auto mechanic generally does have some rough idea of how much a given repair costs (inclusive of labor and materials) or at least can easily inform him/herself. It's a basic two-party information asymmetry where the professional making the decision has more information than most consumers.

In medicine, physicians often have no idea themselves what the total cost of treatment will be, and there are various structural and economic factors that discourage or make it very difficult for physicians to find this information. This is a very different type of information asymmetry, where both the providers and the consumers lack information.
Neither pedestrian crowding nor travel distance is an issue in walkable cities, because public transit and cycling is compatible with a walkable city. There is nothing difficult about it, there exist thousands of walkable cities.

Another concept you may learn about is „mixed used neighborhoods“. It turns out you dont have to separate out working and residential areas, this will reduce travel distances. A related concept is the „polycentric city“.
