How do you propose we handle logistics or emergency vehicles? I’m all for more walkable cities but rip them all up and replace them with what? Rails which are more expensive and less flexible? Pneumatic tube? Even if you switched to single person cargo bikes you would still want dedicated areas for vehicles versus pedestrians.
This problem has been solved by equipment designed for narrower roads. It is not a hard problem to solve and cities like this have been around a very long time.
There are literally solutions to every issue you bring up that are already on the market.
> How do you propose we handle logistics or emergency vehicles?
Find the the width of said emergencies vehicles, and then build bike lanes that are a little wider than that: the emergencies vehicles can drive down them quite easily (and cyclists can get out of the way quite quickly).
Alternatively, if a city has trams, created segregated rights of way, and the emergency vehicles can use them.
Wood frogs only live 3-5 years, so they probably only go through a max of 5 of these cycles. I wonder how much cellular damage they accumulate during these cycles that they can tolerate due to short lifespans. They also have ~10,000x less neurons than a mammal.
Even if you had the biochemistry that was able to do this, how many cycles could a higher life form tolerate this, assuming it would even work? Complex life seems to sacrifice some resiliency, such as the ability to regrow limbs. Amphibians already seem to be particularly adept at regeneration.
"frogs don’t freeze once and stay frozen. Instead, they spend a week or two freezing at night and thawing during the day until the temperatures drop permanently below freezing"
Oh sorry, I more meant specific to the times when you harvest maple syrup.
If you didn't know, you need to wait to harvest maple syrup until you have a series of days when the daytime temperature is above freezing and the nighttime temperature is below freezing. This causes the maple sap to flow and allows it to collect in the bucket.
Some animals regenerate, some form scar tissue. It's thought that scar tissue is a cheaper and faster mechanism than regrowing limbs and has thus been selected in many cases.
Yeah it does form a clot and a thin skin layer, but it remains somewhat like a wound much longer and is easier to hurt again than scar tissue covers up a wound quite quickly.
> The only animal that really does it properly is the salamander
Vertebrates are animals, but not all animals are vertebrates.
A lot of invertebrates can regrow lost organs or even heads. Insects lose it for the luxury of having wings, but other arthropods can regrow lost limbs if they live for enough moults. Planarians can regenerate everything.
I wonder how many of them are caused by internal political struggles. When you have a lot middle management they spend a fair amount of time on resource allocation, both current and future employees. So it’s a constant fight to obtain and maintain headcount.
Hiring pipelines can be longer than the planning cycle. So you may have 3 open headcount one week, and then lose it the next because some other Big Initiative should get it instead. Or the head count flip flops between local and overseas hires. Or the level they are hiring for changes. Each time this changes, new positions are posted.
Basically companies don’t know what roles they hiring for long enough to get candidates through the process.
What follows is anecdotal conjecture: Grubhub has not really evolved much beyond the same core business model they have had for the past decade. The other companies are doing all sorts of partnerships, rewards, referrals, gamification of algorithms etc. Grubhub stagnated while these companies innovated
> The other companies are doing all sorts of partnerships [..]
GrubHub partnered with Amazon. Amazon Prime now includes a GrubHub+ account.
I have Prime, but have yet to use GH+, but that's more because I just stopped getting food delivered in general. Not because of the price (I used DD and had the DashPass which is very much worth it if you get at least 2 deliveries/month), but because I started getting deliveries with missing items. When that happens, they won't offer to do another delivery, they'll just either refund the item or I can go pick it up. Both options defeat the purpose of ordering delivery. I either don't get my food, or I have to leave the house.
GrubHub was always my go to. That miiight be just because I lived in Chicago when it launched so it was the default for me for so long. I used it pretty much exclusively all through Covid lockdown, but have since stopped doing delivery much. Maybe once or twice a month. I do not have Prime (so I don't have GH+), but my credit card provides "free" DashPass so I now pretty much exclusively use Door Dash when I do get food delivered. If it wasn't for the free DashPass I'd probably still use Grub Hub
Another armchair opinion: "GrubHub" has negative connotations in a food service situation where you're already so far removed from being able to grade how skeevy a kitchen is. Cheap chinese takeout from UberEats sounds cleaner than from Grub Hub...
I agree. I think a lot of the growing pains of that industry were attached to GrubHub's name. Possibly fairly, but it still is a bit of a net negative image wise.
Agreed. I spoke with a small restaurant owner last night (he was delivering catering for a corporate event), and he mentioned in passing that GrubHub was the only platform he wasn't on because of how aggressive and exploitative they were in terms of fees.
Doordash prioritized selection, they did online ordering even when restaurants didn't want it. Eventually the demand was high enough that restaurants adapted. Grubhub focused on the traditional take out restaurants. Doordash also mixed in multi-delivery to handle mixed alcohol/food purchases.
Beyond this, tech always follows a power law distribution in returns. Doordash is the number one player, and as such will be about 10x bigger than the next runner up. How much of this is network effects/first preference vs. manufactured return is anyones guess, but most people do not want to spend time price matching doordash/grubhub on orders - so whoever has the bigger network/more customers will get the most folks.
DoorDash and Uber Eats also operate internationally and have a single cohesive brand whereas each country seems to have its own Just Eat-owned service as a result of acquisitions: JustEat in the UK, GrubHub in the US, SkipTheDishes in Canada and Menulog in Australia. All with the same branding and logo but different names and with distinct mobile applications.
Do DoorDash and Grubhub have the same business model? DoorDash handles logistics end-to-end; as I recall (it's been a long time since I've used Grubhub), they at one point did not, but were instead just a market front-end to a variety of different delivery services.
I use Grubhub regularly, they almost always have their own drivers. For a few pizza places that had existing delivery services, they're just a front end onto the pizza place's delivery service.
I have never used any of these delivery websites, but I assumed grubhub was fungible with Ubereats/Doordash/Instacart. All of them being websites that pay independent contractors to pickup and deliver things.
Maybe this was different per region, but I used GrubHub when it first launched in Chicago and even back then they had "their own drivers" (contractors same as Uber/DoorDash).
However, I wouldn't be surprised if their roll out involved capturing businesses that already offered delivery drivers until they had a critical mass of drivers in the region or something.
I think Doordash realized people in middle America would pay to get Taco Bell and McDonald's delivered while Grubhub never really moved out of big cities.
having worked at grubhub and spent a fair amount of time in discussion with ceo/founder matt maloney:
- the leadership during the peak of competition for mindshare in the space was exceptionally weak and overconfident. the grubhub/seamless merger led to a completely split company culture between NY and chicago.
- when they were on top, they were a shitty company with scummy practices (even for the space) that made restaurants very skeptical of them specifically. grubhub effectively ran like a protection racket. they bought up tons of "menu pages" websites and restaurant listing sites and launched fake websites to overtake the online presence of grubhub restaurants (including replacing their phone numbers in google summaries with voip numbers, calls through which restaurants were billed an "order origination" premium for.) they broadly resisted the desire of their restaurants to share ownership of their customers (or even be able to determine who their customers were.)
- they completely lacked the ability to plan long-term or even guess the consequences of any action they would take and would do things like "suddenly, without warning restaurants, offer a 50% off deal on lunch all across new york city," leading to huge numbers of canceled and delayed orders and further eroding their public perception.
- they were already public by the time that uber eats, doordash, and postmates were really aggressively entering the food delivery space and thus had to grow and ship with realistic constraints instead of burning investor money to disrupt in hopes that they would be profitable.
probably a million more reasons beyond that, but just off the top of my head a few ways the ball was dropped/the deck was stacked against them.
Write out what you want to do in a single line. Then make a list of items needed to achieve that. Then split each of those items into 3s. Then split each of those items into 3s, again. Do this enough, and you will have the code you want to write. Then it just becomes a pseudo > real code transition, and LLMs are pretty decent at that.
I really think we do a number on kids expecting a 100%, perfection, as a goal. And then only give them one chance to achieve it, but ask them to do it day after day for years. It creates some really unhealthy coping mechanism.
It really warped my perspective when I moved out of the USA to Europe as an adult and found out that's not how school works elsewhere in the world. Still coping with it lol.
Could you elaborate? I always found the "grading on a curve" a distinctly American approach that leads to grade inflation and an overall lower academic level. Now, granted, the US provides very unique opportunities for students that want to go above and beyond, but that's another story.
Yes, but you then need to have an already developed full supply chain, and for that you need to bootstrap your energy production first hand.
My personal hope is that there might be some untapped resources of hydrocarbons or methane in Mars that could be used to generate energy from local sources.
Local hydrocarbons could help for making materials/chemicals but they wouldn't help for energy. Mars doesn't have free oxygen in the atmosphere so there's nothing to burn them with.
I don't know the exact levels, but radiation+plants doesn't always equal death. Plant genomes tend to be much larger to animal genomes, and much more copies of specific genes.
