I traveled to the US in 2014 on a sponsored trip to research drones for agriculture. My report covered off on some of the technical challenges rather than the business side of it. You could see even in 2014 everyone had great ideas but profitable execution was going to be so hard. My report is here for a look back in time http://www.nuffieldinternational.org/rep_pdf/1438074605BenBo... . I then went on to start a business processing and providing satellite imagery in agriculture because I couldn't figure out a business model that would work for drones.
Why is there no supply side software for Uber drivers like in ad tech?
You aren't wrong, but the two are tightly related. LEGO's competitors are also selling many licensed products, but LEGO's position as the best quality brand in the market has allowed them to secure contracts for the most popular IP (Star Wars, Marvel, Minecraft, etc). Their competitors are left with less popular or less family-friendly IP such as Halo or Star Trek.

Its also worth noting that some of LEGO's competitors don't worry too much about IP laws. You can buy a clone brand X-wing for 50% of the cost of the genuine set, but the quality is significantly lower in my experience.

This looks great, and I wish you all the success in the world. The domain is your key asset, IMHO.

1) When did you start, and how long does it take you to sell an acre?

2) How do you plan on "releasing" more regions? Is the next region going to be (drumroll) the adjacent 160-acre square? Do they want you to complete one square before opening up the next? Does anyone actually keep track of which acre belongs to whom? How difficult is it to get more land trusts on board?

3) I'm looking to offset my emissions, so my key metric is $/t – how much does it cost to sequester a ton of CO₂ that otherwise would have stayed in the air? Any rough estimates?

That's international, not domestic. International airport zones are very weird spaces, because they are not technically part of the destination country, and fall under a variety of international treaties.

The process you’re describing is called recuperation[1] and I believe your skepticism is well-founded. The effects of these drugs on the human mind and culture is more powerful than any other drug in history. The effects may not be immediate but I believe they will be more dramatic than any other pharmaceutical society has experienced so far.

Right, it isn't a debate. The decision has been made.

Not giving a reason also allows the person to form their own story about what happened, which I think can help some people protect their egos a bit.
There is nothing wrong with defending valid science against discredited, unsubstantiated, repeatedly debunked crap.

Accepting their points as valid and not disputing them just leads to the perception there are two equally valid opinions about the topic, when one of them is fringe and makes bad arguments. We do ourselves no favors by that sort of attitude being common and accepted.
i had a similar experience with Turo. The car would lock and unlock with a bluetooth connection and would not start unless the bluetooth connection was made. I went on a fifteen minute hike about an hour off the main road to see a redwood grove and when I got back the app had logged itself out with no action taken on my part. We had to hitchhike for 4 hours back to a hotel so that I could log in using my Google account, then hitch hike back to the car. The car itself was unlocked the entire time because we could not lock it. I wonder if anyone else has had an experience with Turo being logged out. Could a certificate or token have expired?
So much ignorance in this post. You do realize Tesla engineers and designers all came fro other car manufacturers right? Even down do the audio folks who came from Bang & Olufsen.

Part of that is that LEGO has a policy against making any models including guns.

To this day I deeply miss the ability to, when bored, wander down the hall and see whose door was open and what was going on, or to leave my own door open and get drawn into whatever interesting thing arose on the hallway. But aside from aging out of college myself, far less people are even getting access to that in the first place. The entire "dorm" model is dying at colleges, as the residential buildings, though still colloquially called dorms, are really just apartment buildings, except more expensive and they kick you out for a while every couple months.

No, the text does not have the same amount of information in every language, because they are talking about the information in the audio, not the semantic value. Your brain categorizes each syllable it hears into one of N classifications, where N differs by language. So the max intelligible playback speed (in syllables per second), multiplied by the syllabic entropy (in bits per syllable), tends to land on 39bit/s.
Designing database: split into different tables or group them together?
I am fairly new to database design and now trying to build my own forum-based application. The app will have nested categories as

countries > systems > levels > subjects

In every subject category, user access the same type of data e.g. user can post and answer a thread, can reply to each answer accordingly. Users can search for topics with particular strings ( Just like how stackoverflow or quora works) and 80% of the time they will only search for topics that are relevant to their subjects. That means highly unlikely they are going to access other country, or other system or other level but I want to keep that functionality as well.

I am thinking whether should I follow the standard database design and separate the country, system, level and subject into separate tables and use their primary key as foreign key to a particular forum thread. But my concern is performance issue, since there will be heavy usage of searching for particular topic from the users when they key in strings. Imagine every search will have to trigger the JOIN functionality.

However I did some research and found that the accepted answer here https://stackoverflow.com/questions/8479252/database-design-3-types-of-users-separate-or-one-table suggested that if the forum thread has the same attributes, it is best to group them into one table together. However, it will have performance issue too when it comes to search functionality. Every search will have to traverse the database row by row, and there are rows that are irrelevant in terms of the country, system, level and subject attribute. Imagine the thread table rows grew to hundred thousands.

What would be the best way to go? Or should I consider NoSQL? I am looking to integrate the DB into AWS backend

They exist and are used for long distance drones.
I assume he's referring to the NHTSA study which was released on the last day of the Obama administration and purported to show a 40% reduction in crash rates. It's still the highest search result on HN for "Tesla Autopilot."

That study was later shown to have employed sketchy data and egregiously flawed methodology. A deeper dive showed that the crash rates may have actually gone up with Autopilot. HN discussion here: https://news.ycombinator.com/item?id=19127613
i wonder if there's a constant average reading speed (in terms of bits per second) across written languages. chinese is obviously more dense per symbol than english, but is each character processed more slowly as a result, preserving constant data rate across languages? also interesting to consider how much harder real time, verbal translation would be if data rates differed.
Every Angle of the Porsche Taycan Turbo S in Pictures
Sounds like a first amendment issue. He should get an attorney and look into a section 1983 lawsuit. A man in Colorado was detained, handcuffed and held in the back of a police car for filming police and got $40,000, along with the city agreeing to train officers on public photography and the first amendment. Maybe it'd send a message and hold them accountable, but then again cities and counties have insurance policies to pay for it anyways.

I wish more people were aware of their rights, it's sad people who are supposed to protect and serve, and sworn an oath to uphold the constitution yet they willingly and knowingly take advantage of uninformed people.

I am starting to wonder if police officers and even some judges who get sworn in have even ever read the constitution, or just raise their hand and repeat what they are told as part of the oath. Should quiz them on the constitution before they are given the oath, and if they fail the quiz they are disqualified from taking the oath and have to get held back until they improve and try again.
Pair programming stations? That actually sounds really cool if you’re in the right frame of mind
> it's just a cultural thing and it's easy to make graphical applications with a TUI-like input model

I agree with your points, but I think this part is an important aspect to it.

Sure, people (or more likely "developers, writing for developers") could write GUIs which are as keyboard-oriented as TUIs. But I don't think there are many common examples.

With TUIs, it's more likely to be keyboard focussed and support plaintext file formats. (Again, that seems cultural).

Another advantage to TUIs is the flipside of "only 1 font size, limited font styles": with a TUI, the user can set the terminal emulator's colour scheme and font sizes.
Sometimes this won't work well. But it's a degree of customisation you don't really get with standard GUI programs, and isn't common for flashy websites.
There are many Tesla Autopilot accidents under investigation, and their relative infrequency is due to the fact that a.) accidents themselves are rare, and b.) Autopilot (mercifully) has yet to see widespread deployment in the U.S. vehicle fleet.

Is the index of refraction of the Earth at low radio frequencies really 1? I'd expect it to be higher, and so there to be some slowdown for radio waves.
Hi!

You are correct. The first usages of MDMA (the defining ingredient in ecstasy) were in therapy.

If you have severe depression (or severe anything really), I would not recommend experimenting without an experienced guide. Think of it like like scuba diving or sky diving: first you learn how with those who already know.
LEGO is doing very well and spending a lot: https://www.bloomberg.com/news/articles/2019-06-28/legoland-...

As a parent I don’t see many competition for LEGO: Duplo for toddlers, LEGO for kids, Mindstorms to teach kids programming, Technic for older kids. No soldering needed and can be used in relatively small apartments. And quality is a big topic here - LEGO uses molding equipment with pressure sensors, so they all bricks are the same. Cheap knockoffs frustrate kids, because every brick is different and sometimes one can’t join them at all. And you can build anything you want with couple sets since LEGO provides all the instructions online!
True. But some of us still like them.

I'm not hard core enough to have a pre-computer vehicle, though.
So you could just call and leave a reasonable sounding voicemail compelling them to call back?
There's also Macrovision's response to Steve Jobs, following Apple's decision to exclude DRM from the iPod (arguably a major factor in the latter's popularity, and path-paving for the iPhone):

That’s not the context of Macrovision’s response. It’s not that Apple “excluded” DRM from the iPod. The real history.

2001- Apple did introduce the iPod with no DRM in 2001 but it made it hard to copy music from it.

2003 - When Apple introduce the music store, it added DRM support to the iPod, but for the time, and easy built in way to circumvent it - burn the music to a CD and re-rip

2007 pt. 1 - Every digital music store was struggling because their DRM wasn’t compatible with the iPod. The music industry wanted Apple to license FairPlay. Apple refused and Jobs posted his “Thoughts on Music” letter on Apple’s front page where he said instead of licensing FairPlay, if the music industry allowed all digital music sellers to sell DRM free music, they would have cross platform compatibility.

The Macrovision letter was in response to this.
> Adults drive into stationary objects all the time

I agree. But do they when alert and focused and when they clearly see the object? I highly doubt it.

This Tesla was all of those things, and still crashed.
Some models it’s much higher, but overall definitely single digits in the U.S.

Europe has a much higher take rate on manuals.

Of course the top comment is apologia.
The British royal family is one of the largest landowners in Europe and, accordingly, receives one of the largest chunks of EU agricultural funding.

I guess the same is true across countries: former royal/noble families hold onto the land of past glory. But should we really accept this? Is a king's claim not simply the land of the state once the country transitions to democracy?
I think there is a distinction between "flux of incoming information" and "net knowledge gained by human as a result of incoming information".

You're literally using a graphics rendering engine for a script someone wrote to handle how it displays the pictures on your screen.
You should be lucky optimisation and operational benefits of web browsers have come as far as they have.
Web interfaces are nothing more than a miracle, and you're complaining that the ad-hoc nature of putting up a website and having it render in a magic box is too poor quality for you because of RAM numbers. Great.
I hope you’ve reported that to the app developer. That’s a potentially fatal problem.
As long as browsers are heading into the direction of more and more functionality, APIs and complexity, I get the feeling that being un-fingerprintable is going to be a lost battle. The best you can do is to be a unique device every single time and thereby defeat server-side profile building.
This... sounds like it’s on you. If this is in the US, the “flier” is going the normal speed of the road, and you’re driving dangerously slowly.

It’s hard to tell that something directly in front of you is approaching. It’s just not something our brains are good at, compared to detecting lateral movement. Especially when it’s so unexpected. One of the first things they tell you in motorcycle safety class is that “constant bearing, decreasing range” situations are extremely dangerous.

> If customers ask for 1% of index funds to be sold, index funds have to sell 1% of their holdings in the exact ratios defined by the index

I'd like to point out that while this may be the case for traditional mutual funds, it is not for ETFs. ETFs don't redeem shares for cash they redeem them for equities in the underlying index. So ETFs don't actually buy or sell any securities unless they rebalance.
I can't find any recordings of 800 WPM synths. Would it be possible for you to make one? I'm curious of what it sounds like.
I'm doing that successfully for years. But I added more: https://github.com/perl11/cperl/blob/master/pod/perlcperl.po...

The .git/cache is a submodule, so others can easily rebase also. And a lot of helper scripts to rebase and pull --rebase all work branches automatically. All current branches are constantly rebased to master, others default to pull --rebase (aliased to lb), with the shared. git/cache there are no conflicts for years.

I'm also doing this for several forks automatically, like adding patches and CI smokes to popular repos like clisp, libffi, openssl, pcre2, coreutils and many more. These are rebased hourly, conflicts appear maybe once a year.
How to overcome information overload. Any advice?
I always feel like I am reading or assimilating way too much information. How you all manage this? How to beat FOMO on something interesting.Greatly appreciated any advice or thoughts on this.
They aren't talking about the semantic information of the word "trump". They explain the methodology for calculating information, and it's per syllable (based on the number of distinct syllables that are part of the language's phonetics). So, for English speakers, 'trump' has exactly 7 bits in it. That exact syllable may or may not exist in another language, but if so the same singly syllabic word "trump" would have a different number of bits to a speaker of that language. Maybe next time RTA?
I doubt that there's a universal rate - a universal mean (within the context of a shared language) makes more sense.

Every conversation acts as its own handshaking algorithm from which context is derived, and contexts will vary greatly in terms of amount of language required to convey concepts.

Jargon rich conversations between experts have the potential to transfer information at a rate far greater than average.
I doubt they are getting paid to share any data at all. Usually, the point of 3rd party services is for improving the service or keeping it bug free and functional.

I would imagine they have some services that are logging JavaScript errors and probably some that are tracking how people use the service.

If you have a Freemium or tiered service especially, you have to understand how people use your service in order to convince them to pay or upgrade.
Do you happen to have any more info on this?

Well, we could also talk about the time the Tesla accelerated into a gore point when the lead car followed the lane to the overpass. Or the couple of times the Tesla drove into a semi trailer. Or the several other stationary emergency vehicles they've hit. At least the semi's were moving.

We don't really know how well the Tesla automation does vs human drivers, because the statistics are complex, and Tesla only gives us deceptive summaries.

The capabilities that Tesla cars have aren't that much different than other luxury cars, but the other manufacturers don't have NTSB investigations, because their marketing isn't convincing people the car can drive itself.

Yeah but mostly on BLM land, and that's kind of what it's for? As long as the local USFS rangers are writing tickets, they mostly stay out of national forest. I'm never seen them at national parks, wilderness areas, etc.

My college had conventional dorms, and then they also bought and renovated a bunch of the houses in the surrounding neighborhood, capable of housing maybe 6 or 8 students each. I lived in one of those houses.

Today, one of my kids is presently in a college dorm.

One thing was notable about the dorms, namely: The college is a great landlord. Dorms tend to be reasonably secure, safe, and sanitary. Repairs are made promptly and correctly. If something goes dreadfully wrong with a dorm room, you can be in another room within a few hours. Because the dorms are designed for college life, the distraction of dealing with your living arrangements is kept to a bare minimum.

I can imagine, that folding would work if you put the clothing in well defined positions. Like putting clothes on flat surface, camera identifies exact piece and decides how to fold... But then you need well working mechanical parts and it will be expensive. A good washing machine goes for 700+€ and it’s a drum, electric motor, controls and an enclosure. Would you pay 7000€ for a folder?
I don't know man. Index funds seem to be the safest bet you can make as far as balancing risk and growth. You're betting that the world in general won't collapse over the long term. And if it does any high growth strategy is probably going to collapse with the general world as well so isn't that much safer.

What is fascinating is that here is an article claiming that one of the safest bets you can take is the same as one of the biggest most corrupt and deplorable scams of the last 50 years. Now that's interesting because we want to take a look at who wrote that, who published it, and wonder what the heck they are up to peddling this view.
