Isn't that a feature, not a bug?

Don't we want to incentivize people to get more fuel efficient cars?

I mean sure, if one day the majority of the cars are electric, we'll have to adjust how they are taxed, but for now why don't we leave the incentive for people that buy a fuel efficient or electric car.

That's absurd. What if the driver is someone who cannot afford the high rent price at the city center and commutes 20 mi every day from a cheap suburb to work?

I'd be fine if the ultra-progressive SF politicians could just mind their own business and not to dictate other cities and towns in the state on how to govern.

The state has a hard time finding money for fixing roads because of Priuses?

I am not sure that this adds up...

If they’re looking for money, just raise the taxes that make more sense to raise (least painful, most money), not add a tax that affect those who drive most in crappy cars (and really who don’t give a damn about road state in LA in the first place)

> I'm not sure you're clear on what we're actually disagreeing about.

To be clear, I disagree with your claim that the QM description is not correct because it leads to FTL communication.

If you stand by that, you're wrong. If that's not what you meant, then there is no disagreement.

Now, if I understand your latest comment, you say that it's "Only in a hypothetical case [...] where Bob has chosen N/4 particles at random and those just happen to coincide with the particles that Alice measured."

This is like saying that two standard 52-card decks can be used for FTL communication, in the hypothetical case where Bob picks the same card that Aliced picked. If you think that is FTL communication I cannot agree with that. This kind of "FTL communication" doesn't present any problem at all for the QM description.

Maybe I'm missing something, but I don't see in your description of the experiment any trace of potential FTL communication. You're not even trying! I would like to see something like the following (but I understand you cannot provide it, because it's impossible):

1) N EPR pairs are distributed

2) Bob does something ("selects N/4 particles at random and tests for first-order interference relative to P" or whatever) and concludes that "Alice has done something to her particles" or "Alice has not done anything to her particles" depending on the result of his measurement.

[The prediction is done at this point, the verification step follows.]

3) Alice tells Bob if she did or not measure her particles before he did. Or Bob tells Alice his prediction. Or Alice and Bob tell Charlie and he performs the check. In any case, this requires slower-than-light communication.

This experiment can be repeated several times to see if Bob's prediction is right every time or if at least there is some correlation between what Alice did and what Bob guessed.

Your description has additional steps involving communication between Alice and Bob before there is any result or prediction. It is not in any way incompatible with the standard QM formulation that you reject, as far as I can see.

It looks like if, in the card-picking example, Bob picks a card and then compares his card with Alice's card. If the card is the same they announce that FTL communication had been achieved. If the card is not the same, they try again. If you think this is not a fair characterisation, please make clear what prediction is Bob doing before communicating with Alice.

To make my point as clear as I can once again: according to QM, Bob cannot tell if Alice has performed or not a measurement on her side. For any measurement that Bob can do on his particle, the predicted distribution of outcomes conditional on "the entanglement is broken, the particle is now in an unknown pure state" is exactly the same as the predicted distribution of outcomes conditional on "the entanglement is intact, the particle is not in a pure state (the pair A/B is still in the pure state E)". Whatever the outcome he gets out of his measurement, it cannot be evidence for one or the other.

This spectrometer is inexpensive:
https://publiclab.org/wiki/desktop-spectrometry-kit-3-0
The problem is calibration, you would need to calibrate with sources like lasers or fluorescent light with known spectral peaks. Then you could use the spectrum to calculate CRI. You are just calculating cri (which has its own issues), so even with a crude device some spectral error is ok.
You're afflicted right now by one of those beliefs that is simultaneously obvious, intuitive, and completely false.

See http://www.ppic.org/content/pubs/report/R_704LRR.pdf for instance: "[In the Bay Area,] Low-income workers walk, carpool, and use public transit at higher rates than their more affluent counterparts".

And on page 86 you can see that 70% of high-income folks drive alone to work. Amongst poor people (their term), it's 51%. Meanwhile, 5% of high-income residents of the Bay Area take the bus to work. Amongst poor people, 12%.

Anyone feel kinda guilty working in tech? There's thousands and thousands of us trying to make the next app, putting forms on pages, making video games, shopping carts, crypto apps, etc.. We're smart enough to learn biotech and make advances, but the investment just isn't there.

You're not going to find plentiful jobs in biotech. And starting up a new company is nowhere near as easy as it is in tech. I know almost no one from school that got into it. The one person I do know is working on genomic sequencing for race horses..

I hate to say it, but it really needs steady/consistent government funding - both training students and supporting companies. We could be way further along in biotech overall if there were actually a good number of us working on it. No sane investor is going to put money into R&D that will end up failing 9/10 times. And even if you hit on something, the healthcare system is so jacked, recouping your costs are just as hard as developing the product.
Does anyone else have trouble getting invested in articles on income inequality or demographic economics when there are lines like this:

"For each of the two years he was on Kimmel, Allison earned about $208,000, which in Los Angeles, the second-most-expensive city in the U.S., represents a middle-class lifestyle"

That amount of money would put you in the top 10% for Los Angeles for household income - which means if you had no dependents (or a spouse that at least made some money) you'd easily be top 5%. In no way is that middle class.

There are similar articles like this: https://www.laweekly.com/news/it-takes-nearly-100-000-a-year...

which seem to use stretch metrics to make a point. It says you need 100,000 to rent the median house. First, it doesn't say how much you need to rent any house. Second, the city of Los Angeles is mostly apartments for those without children so you would need far less than 100,000. The only reason you would need a house is if you were a couple - but in the case getting close to 100,000 in combined income is much more achievable than doing it solo.

I know neither of these points speak to the larger point of the article - but it becomes harder to take the rest of the article seriously when they stretch the economic truth so much. As a resident of Los Angeles I can attest people get by with many magnitudes less than 200,000.

It's not a good analogy because it doesn't require individuals at the top of their field. The only reason Netflix is winning is because they have massive amounts of content and integration into many devices. Both of those are business arrangements and have no requirements for the best engineers in the world. Just competent ones.
Hate to break it to you, but $360k total comp for a senior engineer (the only type Netflix hire) is at best on par with FAANG.
1. Don't promote based on ranking in current role. The new roles that you are promoting into aren't the current role. Being a good X doesn't mean that you will be a good Y.

2. Organise your company around rewarding excellent work. Ranking systems reward being good at the ranking system. They rapidly become the whole focus of the organisation, I have seen >10% of an organisations time burned on simply running the system, the amount of time manipulating it was unmeasured but by observation probably greater than that.

3. What is the objective : reward great people, remove terrible ones. The latter must be done at any time, it must be fast, it must be transparent. If your system doesn't do that then it's a bad system. Stack ranking and all ranking/global performance management systems fail to do any of these. They introduce relative performance as the bar, they introduce admin. The former is potentially done by a stack ranking system, but if you are a star in such a system then seek not to work with other stars or you will descend the stack - this is bad.

4. Pay rises (not promotions) follow business performance - if the team's unit is winning the money for the team will be there. But the team might be poor compared to another team that is in a weak unit. This is natural for businesses and what should happen is that the talent from the good team should migrate to the winning unit. Businesses need to manage this with an eye to the future (building business) but stack rankings don't help this.
It's not just having to understand what a class is, it's also having to know and remember to add a constructor to your class just to call `this.handleSomeEvent = this.handleSomeEvent.bind(this)`.

There are multiple Netflix employees in this thread, all citing the same $360k total comp figure.

I'm guessing GP is someone who heard base salary data for Netflix vs other FAANGs, and doesn't realize how much of total comp at a non-Netflix FAANG would come from bonus and RSUs.

We should farm and eat endangered species to save them. That's the only way of incorporating endangered species into our economic system. We can export wolf meat to the Chinese. Imagine a chain of restaurants selling endangered meat because of the ecological benefits of eating organic AAA grass-fed endangered meat and maybe it's even low in saturated fat as a bonus.

That said, has anyone had a look at the paper? What I can't figure out is the assertion that, "In contrast to commonly used RAD implementations, the algorithms defined here involve no graphs, tapes, variables, partial derivatives, or mutation. They are inherently parallel-friendly, correct by construction, and usable directly from an existing programming language with no need for new data types or programming style, thanks to use of an AD-agnostic compiler plugin." That would be fantastic, but that's not immediately obvious to me. Generally, reverse mode is extremely non-parallel friendly because we're essentially traversing a computation graph. That traversal can be done in parallel, but figuring out how to partition that graph is probably more expensive that traversing it in serial. Now, the paper makes a big deal about not building that graph and passing along the derivative at the same time as the function. Fine. But does that method really produce a more parallel friendly code and is that as efficient as a more traditional graph or tape based method? Unless I'm missing something, I don't see any benchmarks of the method and what would be really helpful would be a ratio of the run time of a routine versus the run time of the routine with the AD method instrumented and the gradient calculated. The big question is how does this ratio hold as the method is scaled up in terms of variables. If the parallel claim holds true, then we should be able to also calculate the resulting parallel efficiencies.

Anyway, I'm genuinely curious if someone has additional information about the computational viability.

I've built large systems with RethinkDB, and proprietary NoSQL DBs. My experience is this: if you need to query any significant volume of data, you must have indexes. And once you start figuring out the indexes, you're designing a schema. So it's best not to shy away from schema design up front, and evolution during dev. Otherwise you risk very poor performance. On the requirements front: dialog with management and users often degenerates into handwaving. A concrete prototype can help clarify IMHO. Suggest you break out one small piece of the legacy system and prototype a new solution. Disarm the scared seniors by emphasizing that it's throwaway. When the users see something new, shiny and better you'll have the political backing to face down opposing noobs and seniors. That's a double edged sword, as you'll also have the pressure to deliver. Good luck!

I did too a few years back, and it clouds the brain no-doubt. It got to the point where something had to be done, and so I set everything aside and dedicated 6 months to figuring out how to fix it.

I have posted on the effects of sprints several times over the years so rather than repost again, here's a link to the threads: https://hn.algolia.com/?sort=byPopularity&prefix&page=0&date...

Running sprints were key, but inflammation due to diet was part of it too (a latent issue not widely discussed, but a factor more common than you might think). I solved that by eliminating certain foods one by one that are known to cause inflammation. Peanuts were one, and eliminating aspartame (diet coke) had a noticeable effect within just a few days (I verified it wasn't the caffeine by adding back tea and coffee, and those had no noticeable effect).

Here's some links to the original Harvard and USG research findings on the issues with aspartame and artificial sweeteners/flavors in general, like why it's banned it baby food: https://news.ycombinator.com/item?id=6703802

I think that probably almost anyone is aware of the danger that a system like that, its just that everyone is deliberately ignoring it and weighing it against the PR storm. Its pretty much universal, to throw due process out the window is something that a vast majority of people want to do after any heinous crime committed, something politicians also always exploited.
>Sometimes one way to win is to play along and lead your opponent into a trap.

Is the victory condition getting him fired?
I think the article is factually correct but makes it sound a little more complicated or advanced that it probably is. I mean, depending on how you interpret it you could think that it does basically "hey, this looks like a fire hydrant, let me paste a fire hydrant in there" which is obviously not exactly something AI can do reliably today, especially on phone hardware.

I'm guessing that it works similarly to low-budget astrophotography but with the computer doing all the busywork for you: when you want to photograph stars or planets and you don't have a fancy tracking mount to compensate for earth's rotation you'll have very mediocre results with long exposure. If you expose a lot to see the object clearly then you get motion blur. If you use a shorter exposition to reduce the blur you don't have enough light to get a clear picture.

One solution is to take a bunch of low-exposure pictures in a row and then add them together (as in, sum the value of the non-gamma-corrected pixels) in post while taking care of moving or rotating each picture to line everything up. This way you simulate a long-exposure while at the same correcting for the displacement.

An other advantage is that you can effectively do "HDR": suppose that you're taking a panorama with the milky way in the sky and some city underneath it, with a long exposure the lights of the city would saturate completely. With shorter exposures you can correct that in post by scaling the intensity of the lights in the city as you add pixels (or summing fewer pictures for these areas). This way you can effectively have several levels of exposures in the same shot and you can tweak all that in post. In the case of the city/milky way example you'll also need to compensate for the motion in the sky but obviously not on land which is also something you can't really do "live".

I have a strong suspicion that it's basically what this software is doing: take a bunch of pictures, do edge/object detection to realign everything (probably also using the phone's IMU data), fit the result on some sort of gamma curve to figure out the correct exposition then add color correction based on a model of the sensor's performance under low light (since I'm sure by default under these conditions the sensor will start breaking down and favor some colors over others). Then maybe go through a subtle edge-enhancing filter to sharpen things a bit more and remove any leftover blurriness.

If I'm right then it's definitely a lot of very clever software but it's not like it's really "making up" anything.

I am embarrassed to admit this but I use a microwave-safe ceramic dish with lid for steaming vegetables. I put two to four tablespoons of coconut oil and 4 tablespoons of curry paste. I heat it up for 30 seconds and mix it and add coconut milk powder. Then I fill it with frozen vegetables and nuke it for 10-15 minutes.

The frozen chicken breasts are cooked in toaster oven for 45-75 minutes at 400f in a cast iron flat plate skillet. I usually start the microwave when this is done, because again I am very lazy and need to run another 20 amp circuit to that spot of the kitchen.

I cut up the cooked chicken and put it in the bowl when it is finished. I have it timed so everything is perfectly cooked. Probably the most offensive and lazy way of cooking this dish, quick and about $2.25 total including frozen chicken, frozen vegetables, paste, coconut oil, and milk.
