That statistic could also be the result of excessive prosecution against black/minorities and not necessarily just jury bias. (Which would also explain the white bias against whites)

That’s true (analogy - you can find out how much the clothes you’re wearing weigh by weighing each piece individually or weighing yourself wearing them and subtracting your weight).

But you can’t change the process mid way through your measurement. We don’t have a way of measuring “consumption of domestic products” so we just measure consumption and subtract the imports afterwards.

X-M is an accounting trick, but when you’re using this model you have to stick with it.

The idea that imports were deferred causes this accounting trick to show its weakness. (Presumably, looking at the data for all of 2025 when it’s available will “low pass” the deferred imports)

Source? None of those numbers make sense.

> The price is somewhat of a guess, several years ago, the hardware in Waymo was priced at $130k by Munro&Associates

10 years ago they had even more sensors dotting the car, instead of one honeycomb on each corner they had 2, so I find $130k hard to believe given what we know about the sensor kit today.

> But since then the cost of the LIDAR sensors fell by 90% or so, reducing the main expense.

I do not know of any lidar that has done that, and Waymo makes their own and we know their price(-ish) (and quantity). I think they’ve actually gone up in price (but also capability - honeycomb 1 vs gen 2).

digitalPhonix··on Coventry Very Light Rail
Source?

They were targeting $7.5k for their in house honeycomb lidars and they have 12 of them - that’s 90k already.

https://www.theverge.com/2021/8/27/22644370/waymo-lidar-stop...

They also aren’t close to the $7.5k target (there isn’t any public source for that so you’ll have to take my word for it).

Also $30k wouldn’t even cover the base vehicle.

digitalPhonix··on Coventry Very Light Rail
Each Waymo vehicle is probably close to half a million USD in just hardware cost.

I don’t think fixed route transport infrastructure is going to have trouble competing on efficiency.

But why would the upstream town be interested in governing what they dump?

Clearly someone/something has to assert the value that downstream towns have the right to unpolluted water. And won't that be the higher level government preventing the upstream town from asserting their rules and values?

digitalPhonix··on Alberta separatism push roils Canada
How do you address issues where tragedy of the commons comes into play? Every individual neighbourhood/smallest unit of government would (rightly) pick the best option for themselves.

Having a large representative base is the easiest way to prevent that.

SFP+ is not a good choice for a consumer device.

From a physical pov it’s not rated for anywhere near as many mating cycles and requires user care to protect against environmental damage.

From a connectivity pov you’re limited to short runs for DAC or extra cost to add a transceiver on each side.

digitalPhonix··on Gamers Nexus to open an investigation into Nvidia's shady business tactics
The same reason I’d be uninterested in reading that the Daily Mail wants to investigate something but interested if NYT wanted to.

I have faith in one to deliver useful investigations and not the other.

> After NVIDIA's huge breach of trust that we covered, we are officially opening an investigation and deep-dive into more of NVIDIA's shady business tactics

Is mostly waffling that could have applied to anything that nvidia did in the last 5 years

digitalPhonix··on India launches attack on 9 sites in Pakistan and Pakistani Jammu and Kashmir
From the article:

That’s a huge loss of aircraft! Are there any corroborating reports or more details about the aircraft/shootdown?

A common joke with firefighters: the difference between a training exercise and a real fire scene is the lack of law enforcement getting in the way.

> Because they're trained first-responders, who have medical first aid training

In many parts of the US they are only trained to EMR level (if that) which isn't particularly useful. Most fire departments require everyone to be EMT and will often have a paramedic on board. Where I am, police are all EMR and will rarely be dispatched to a medical call (unless there's a threat of violence). They will be dispatched to vehicle accidents for traffic control.

digitalPhonix··on Why do econ journalists keep making this basic mistake?
I don’t think those details are what the author is trying to draw attention to.

They’re saying that treating the “minus M” part of C+I+G+X-M is just an accounting step so that you don’t need to manually subtract imports from each of C+I+G (ie. the weighing yourself analogy; instead of taking your clothes off and weighing yourself, you can weigh yourself and subtract the weight of your clothes).

Everything you said is correct (and means that the statement “imports subtract from GDP” is even more wrong) but not what the author is pointing out.

digitalPhonix··on Regime Change in the West
This isn’t opportunity costs, the government had to sell bonds to do all that because wasn’t sitting on cash.

I’m just saying that I don’t think “it was a profitable program” is true.

Factoring the overall benefits to the economy is obviously the right way to judge it and is (mostly) unrelated to its direct profitability.

digitalPhonix··on Regime Change in the West
So they actually lost money compared to the treasury just not selling $426 billion in bonds.

Very rough calculation on my phone without looking up specific yields and dates: 5-year cost to the treasury for selling $426 billion in bonds is ~$443 billion (4% yield)

digitalPhonix··on Tesla drives into Wile E. Coyote fake road wall in camera vs. Lidar test
The checkride required to get an IFR rating quite literally requires you to “read a book” (brief the approach plate to the flight inspector) while the autopilot conducts the initial parts of a precision approach.

A 20 year old avionics suite (GTN 450) does much more than cruise control - you input a flight plan including an approach, it will fly the flight plan, capture the approach signals (VOR/localiser/whatever - which is far more complex than “keeping course”) all the way down to approach minimums.

The report you linked is specifically about general aviation - not about commercial (part 121) aviation. GA lags behind by decades (still uses carburettored engines burning leaded fuels).

In any case, it’s talking about error cases for autopilots, not the operational domain for when they should/shouldn’t be used. The key take away was improved training for identifying autopilot malfunctions and not reduce/eliminate the usage of autopilots in certain scenarios.

> You can not (irl should not) do something else

I’m curious, what autopilots have you used and what capabilities did they have?

digitalPhonix··on Tesla drives into Wile E. Coyote fake road wall in camera vs. Lidar test
> The autopilot of an airplane will not avoid any kind of stationary obstacle, not even a mountain

Well a core part of the flight is colliding with the ground at the end.

But also the hazard of a stationary object doesn’t exist - crew receive an IFR clearance and fly that route; that route won’t have stationary obstacles.

Aviation’s autopilots aren’t “eyes-off” in VFR so that’s a meaningless comparison.

That’s clearly marketed as Level 3. As in, level 3 is publicly available and usable on public roads right now.

From: https://www.mbusa.com/en/owners/manuals/drive-pilot

> Raising the bar in autonomous driving technology, Mercedes-Benz is the first automobile manufacturer in the US to achieve a Level 3 certification based on a 0-5 scale from the Society of Automotive Engineers (SAE). Under specific conditions, our technology allows drivers to take their hands off the steering wheel, eyes off the road — and take in their surroundings

(Specific conditions being the lead car and speed limits you noted, but that’s not what the person you’re replying to is talking about)

Additionally to their level 3 system, they’ve been granted permission to test Level 4 systems not for public use/availability, on a prototype vehicle:

> There literally is no autopilot, which does not require constant attention from a human. This is true for planes, ships and cars.

Can’t comment on ships, but autopilots in planes definitely match SAE level 3:

- Hands off

- Do not require constant attention

- Will alarm and indicate to the user when attention is required

ie. “when the feature requests, you must drive [fly]” from the SAE nomenclature: https://www.sae.org/blog/sae-j3016-update

And this is autopilot that’s been in commercial aviation for decades (so long that it’s started filtering down to general aviation).

digitalPhonix··on Trump says he has directed Treasury to stop minting new pennies
> No the price will become 1.05 and when customer buys 2 it will be 2.10 not 2.05

That's quite literaly against the "various rules to try to ensure neither the seller or buyer always benefited" that the previous commenter was talking about writing software to handle.

No country that has cash rounding rules would allow 2*1.03 to be charged $2.10.

https://en.m.wikipedia.org/wiki/Cash_rounding

(Unless you mean: the price of a single item is changed to $1.05, in which case sure; that's the business's perogative to raise prices but it's not taking advantage of the rounding system)

digitalPhonix··on Trump says he has directed Treasury to stop minting new pennies
How? If you price something at $1.03 so that it rounds up to $1.05, someone who buys two will get it rounded down to $2.05

There is a lot of doubt as to weather that story is real. The story supposedly happened in 2009 when the online Target store was hosted and run by Amazon. Even now Amazon's (or anyone else's) recommendations are not anywhere close to that despite having a decade more experience building recommendations systems. (Yes, Amazon, I want to buy another TV after ordering one yesterday)

> Google Search doesn't have a network effect. Everyone on HN has been saying Google Search is complete garbage for a decade. It still has the same market share (roughly) as it did a decade ago.

It absolutely does. People use Google for search -> Websites optimise for Google -> People get “better” results when searching with Google.

The fact that it’s market share is sticky and not responding quickly to change in quality is sort of indicative of the network effect.

digitalPhonix··on Consumer-grade routers on puny power supplies (2024)

That's what the article is talking about - the output capacitors in their cheap power supply weren't big enough for the peaky load of the router. (Well, probably were assuming a sinusoidal input, but not big enough when the stairstep input has big gaps).
