If the industry needs a better data analysis solution, that's fine, find one or maybe start to build one. But saying "I'll just throw some Python at it" isn't a good solution. It's like saying you're gonna replace a lawnmower with tool steel and a welding torch. Not only is it not guaranteed to end up as a better solution, but you're setting yourself up for a lot more work than you think.
> Secondly it creates dependency between receivers and givers. I'd rather empower workers collectively than make people dependent on welfare. This, in contrast to UBI is I think viable across the spectrum and actually what people want.

This one I don't get. Empowering workers, in leftie politics, usually means some version of labor, wage, union,... protection laws (not saying this wrong, I'm myself seeped in leftisms). Thus creating a dependency to the state to protect one's work from the ruthless.

Where is the principal difference between being dependent on the state for cash vs protection?

Wrt the larger UBI point: I see it more as an opportunity for people to find deeper, more personally meaningful, work. My inner optimist hopes people would seek out more fulfilling, self-determined, work. My inner pessimist sees the Wall-E thing, though I would not call it underpinning. My inner realist would like to see more studies.
While "those unable to stairs up to floor XYZ" can be proven to be a statistically smaller subgroup than "all possible elevator riders", this argument may not hold much water. If you're a wheelchair user or other less-abled person, and your choice is between stairs and an elevator of any sort, you weren't really given much of a choice in that matter.

Covid has completely warped my window of "productive" work. Generally, I now get most of my work done between 2pm and 10pm. Fortunately, the rest of my team has a similar cadence which is why I pinned 9pm as my boundary :)

I previously thought it was complete and utter pseudo science but I've recently started using a near infrared LED light in the morning and evenings and it's immensely helped reinforce a healthy circadian rythm.
The average human driver doesn't need millions of pictures of a stop sign to identify one either. Training current AIs sucks and the results need to be verified because they can be flacky, the current research really doesn't come close to match an organism that spend millions of years evolving the ability to move in a complex 3D world.
Yes! Budgeter here as well :) My YNAB subscription is well worth it, BUT I use YNAB at least weekly. That was a big struggle I had with coming up with a pricing model that made sense here--realistically, it seems like most/many people will only be actively using Itinee for relatively brief periods of time throughout the year, which, at least if I were the customer, would make me wary of long subscriptions.

As a developer/founder I absolutely would prefer regular subscriptions to sporadic one-offs, I just doubt(ed) if people would actually signup for that.

I certainly agree that transitioning to a subscription model would require lower prices to be feasible and may be sufficient to get people on board with "wasting" their subscription for 75% of the year.

As a tangent, I find that it's really hard to get this kind of feedback from real/potential customers (like yourself!) but such feedback is incredibly valuable (thank you!). I wonder if there's a market for some service where I could pay $100 for 3 people to go to my landing page, try my product (free of cost to them, obviously) and then be open to some conversation about their experience. It seems like there could be a market for that given the "Indie Hacker" boom. Maybe such a thing already exists.
New US Dietary Guidelines: No candy, cake for kids under 2
I built a doctor appointment booking website for the Australian market in the early 2010s. I wasn’t much of a web developer back then, so it wasn’t great. I ran out of money and had to go back to work because I had three other mouths to feed. The nail in the coffin was a big, well-funded competitor entering the market. The timing was right, but I lacked the money required to continue putting my time into it.

Why doesn't annotating these functions with @functools.lru_cache(10000000) work?
I can vouch for that book too. About 3 years ago I used it as the main text book for a QC course and came back to it multiple times during my master thesis. For me it was just concise enough to stay focused but not get lost every other sentence (unlike 90% of math books I worked through). However the parent is right in that it is a little outdated when it comes to the physical realizations and maybe some algorithmic findings.

Anyway it was an invaluable resource for me and I would love a new revision from both authors.
I skimmed the studies since the are linked in the main article. It does in fact seem like they bias towards which position they had as a prior, but I would still say that they are useful. Both provide approximate bounds. So we have a lower bound of $9/hr and an upper bound of $23/hr (now this doesn't mean that we should say it is $16/hr). But the things the studies did bring up a lot of questions. Both did nefarious things (lower wage study is including the vehicle cost as part of expenses and higher wage poorly tries to account for "lurkers" by only counting idle times that directly lead to a ride.)

For example, one of the big differences in the studies was how they accounted for "working." One did with app open and the other did idle time that directly led to rides. So if Uber and Lyft are required to pay for idle time, how are they going to handle people that pass on rides and just sit idle? Do you get banned from the platform if you pass on x amount of rides? I'd imagine whatever the policy (not stated in the article) is going to get harsher if they aren't paid by the ride and rather by a combination of hourly and ride. Since it is clearly difficult to actually determine hours working. Or maybe I'm over thinking it and the amount of people sitting idle is actually really low where it isn't a big deal. Does anyone know?

[0] Berkeley released this comparison which is kinda odd and biases towards the lower wage study. The odd things are like #4 how they say the high wage study is void because it includes tips and technically the state doesn't count tips as hourly wage, but if we're talking about take-home that's an important number. https://irle.berkeley.edu/files/2020/07/Comparison-of-two-Se...

> Why do we have to use complex numbers when the system is very much real

If you don't use complex numbers you end up with a bunch of maths that looks suspiciously like complex numbers. The algebraic properties of complex numbers make it a very natural way to express quantum mechanics.

I believe 3Blue1Brown has some good videos on the topic - you really need to learn about complex numbers separately to really see the magic of them (It's largely visual, so it's hard to transmit via text)

Edit: The book "Visual Complex Analysis" is very good if you resonate with its approach - I personally simply cannot click with almost any geometry, so it wasn't really for me although I appreciate that it's really very nice.
My 2c. From the programming perspective, QC isn't much different from GPUs or ASICs: a slightly different model, a slightly different language. For this reason, learning QC now, when there are no QC chips available, is like learning an obscure VHDL dialect to program a not yet released chip. If QC chips become available, I should be able to pick up QC programming in a matter of weeks, if necessary,
> The need for complex numbers in describing a quantum bit. Why do we have to use complex numbers when the system is very much real? What is the real world interpretation?

The world isn't "real" (people rightfully find imaginary numbers a bad name, but real is equally bad). Complex numbers show up all over in physics. As to why, who knows?
We just model what nature does, and it turns out that complex numbers form a very simple (relatively speaking) accurate model.

> The fact that an n-qubit quantum computing system is significantly powerful than classical system because of 2^n states. But, a classical system with n-bits will also have 2^n states, isn't it?

A n-bit pure quantum state can be fully described using 2^n complex numbers, and thus have 2^(n+1) degrees of freedom, which is a vastly bigger space than n bits. While quantum amplitudes are distinctly not probabilities (and more powerful), you can think of the difference in state space roughly by comparing the difference of storing one n-bit number v.s. storing one specific probability distribution over all n-bit numbers.
If Protobuf was just created to make it easy for teams to inter-operate, couldn't you just use a REST API with JSON Schema? If it's gonna be a resource pig you might as well use simple components that are widely supported.
Human beings need a target for vengeance and hatred. If someone kills your child, you can hate them. If an automated car kills your child, you don't have anyone to hate. Saying that this is about safety thresholds is a distraction from the true human problem exposed by automated cars:

"Which individual will held accountable and risk jailtime if their car kills someone you love, and how can this individual be identified from the appropriate government registries within 24 hours of a death?"

Until this is clearly defined in law, automated driving will continue to be resisted under any number of plausible justifications, and arguing with those justifications will have little effect.

Ask HN: Karma Requirements
How much karma do you need to flag, vouch, ect? Thanks.
XLL lets you also write .NET code, basically anything that can compile to a DLL, to make custom functions you can expose in Excel - and it is a pretty old supported integration method by Microsoft with Excel. COM enabled DLLs were another way to do this, but they ran slower.

Not that I have any issue with getting Python in my Excel, but people seem to forget that .NET is also an option.

Getting these capabilities enabled in a locked down corporate IT environment traditionally was difficult but I suspect that is changing.

I have also lived the whole, turning a model in Excel into an app exercise. At the time, we rewrote a fairly complex demand planning app from Excel/VBA to C# since the other dev team members were C# devs and could support the app.

However, during the project, I did a demo of how one could build a Winforms app in VB.NET also, to the developer who was the Excel/VBA guru. He'd had no idea that coding in VB.NET and Winforms was close enough that he nearly could have been doing that instead.

The compiled C# version of the model we built, went from running a single instance of the model in 1 hour, to under 1 minute. We could re-run their model for tens of thousands of instances daily, without breaking a sweat.

Ironically, the rewritten version in C# never saw the light of day as the project was canceled (corporate politics and wisdom). However, the simple optimizations we identified in the rewrite were given to the Excel guru who actually made improvements to his tool that let it run in more like 10 minutes.. and it was even object oriented and modular! He learned he could do a lot more in Excel/VBA that he didn't even know about.

Coding is coding.. just some tools make the jobs easier or harder.
Or they were already working on it and hadn't announced, and he would have spent all the time and more money working on the patent only to see Facebook launch the same thing before he even filed it. Assuming there wasn't already a patent out there that covered this.
In this case, Cuomo killed thousands of people with very bad decisions. Yes, there's a good chance if he did nothing at all, there would have been a lower death count.

The WHO is already telling all nations the lockdowns need to end. There is little to no scientific evidence they've done anything at all! So really, they've likely only done harm and zero good.
Travis autonomy would take a couple years. He spent some absurd sum acquiring the talent for ATG and gave them unrealistic deadlines. The program was a shit show. A pedestrian was killed, the program was stopped, Investor money was lost. While this is not the only factor leading to Kalanick's ousting, it was a big one.
Bitcoin surges to record $28,500, quadrupling in value this year
I don't think that answers the question at hand. The question is about if the driver is actually working (waiting for a rider) or just sitting with their phone on. I don't think this is a trivially solvable thing. But I'd also imagine Uber/Lyft would be more aggressive in kicking idle people off the platform. But that will get complicated because "rides needed" is not a uniform or homogeneous distribution throughout the day, week, month, or year. I'd imagine someone driving as a 9 to 5er would be idle much more often than someone driving on the weekends and holidays. I'm fairly certain good actors will get kicked in an attempt to rid the platform of bad actors.
Everything that I've read suggests the bats from which the virus likely originated can only be found hundreds of kilometers away, so it must have been brought into Wuhan somehow. Either for food, or for research, unless you can propose another explanation?

> The bats carrying CoV ZC45 were originally found in Yunnan or Zhejiang province, both of which were more than 900 kilometers away from the seafood market. Bats were normally found to live in caves and trees. But the seafood market is in a densely-populated district of Wuhan, a metropolitan of ~15 million people. The probability was very low for the bats to fly to the market. According to municipal reports and the testimonies of 31 residents and 28 visitors, the bat was never a food source in the city, and no bat was traded in the market.

Source: https://archive.is/r4Yac

Now, I don't suggest that the virus was created in the lab, or deliberately leaked. But it had to be brought into Wuhan somehow. I just don't consider it dismissible, yet, that an inadvertent leak from the lab could have been the cause. I look forward to all new evidence that may emerge.

If the market was indeed the cause, then in the interests of global safety, wild animal markets of this nature should be prohibited.
I’ll second klelatti’s question about R vs Python. From my perspective Python is just as practical for actuarial calcs and better for building general purpose tools. Is there a reason Anaconda didn’t click?

Ask HN: Is Near Infrared LED light therapy fake science?
I want to say first that I generally regard devices like Near IR LED "therapy" lights as complete fake science and a trope marketed at stupid rich people and bio-hackers.

However, I borrowed a light from a family member recently and found that using it right when I wake up has immensely benefitted my circadian rhythm and I also seem to have more energy without taking stimulants. I've looked up some of the "science" behind these devices [0], even read through a number of the readily available controlled studies that assert a plethora of health benefits from these devices.

Personally, I'm relatively convinced the positive effects I'm seeing are completely placebo or just because I'm sitting in front of a warming bright light for ten minutes each morning.

What are your thoughts?

> Because it is a market optimal strategy. Since consumers express strong preference for emotional headlines, it is optimal to give them that. Consumers frequently lie that they prefer honest headlines, but that is merely a mismatch between their true beliefs and the identity they wish to project themselves as having.

It is also a fine explanation as to why countries often have all these noble rights in their constitutions, and everyday technicalities by which they are legally evaded.

The people don't want these rights to exist, they want to claim they want them to exist. They want to say “Better a thousand guilty men go free, than a single innocent man be in prison!”, but what they really want is conviction upon præponderance of evidence, together with the all to common mentality of “It won't happen to me.”.

There are dozens of toy GB emulators, but nobody has yet emulated the wildly successful Bandai Digimon Digivice. It's based on near-identical technology to Bandai's "Tamagotchi" virtual pet though Digimon was marketed mostly towards at boys and Tamagotchi was marketed mostly towards girls.

It's from the same era as the Game Boy Color and has some interesting features (serial communications between devices, and the infamous "tab cheat" that momentarily disconnecting the battery with a plastic tab to randomize the memory contents).

Interesting how Pokemon is widely emulated, but nobody ever bothered with Digimon. There has been multiple generations of Digivice hardware, so best start at the original.

I'd like to see somebody take on the reverse-engineering challenge. I don't think there's even a ROM dump yet.

They've actually started selling new stock recently (20th Anniversary Digivice), including at retail stores for around $30 each.
