But Doordash don't charge for an unsolicited service. They aren't charging the restaurant at all in this case. They're paying the restaurant's full price for food. Like anyone could.

Then they charge the customer for an additional service actually rendered - the delivery. They charge this as a delivery fee and a markup that they can vary on more expensive items. This is pretty normal for a retail business to do.
But in the best case you might be far better with this option.

I would bet a 5 year warranty means they trust their hardware. Still, when you have so much data and you really care about it, you should use a filesystem that prevents bit-rot and can deal with multiple drive failures.

And backups. Never forget the backups.

I think the usual way to "level the playing field" between in-memory and disk-backed based storage engines for clearer comparison, is to back the disk-backed storage engine with a tmpfs volume.

I believe that the combination of tmpfs + file access — and especially tmpfs + mmap(2) — results in a fast path that almost resembles direct memory access. (If the file or memory-region is opened read-only, the kernel can expose/share the relevant memory pages directly into the process.)
Working on a security solution right now and I can 100% tell you I can think of multiple companies that need an on-site 18TB datastore, even "small" companies. Also have worked with tons of creative agencies. Video, photo, etc all can take huge amounts of disk to safely store.

Sorry to disagree but your assumption that these are "enterprise-class" products is incorrect. There are lots of business needs that require large on-prem storage solutions without being an "enterprise-type" business.

Same as the basis for what I responded to. Nothing.
Good reply, thanks. I am very pro #XMPP. Which is also why I yearn for a couple real areas of improvement & focus:

* MIX. there's a new standard for group-chats/rooms that is far less ad-hoc/special-case, that uses other XMPP extensions (XEPs) very well & enables features people expect in chat these days. it's a good standard. MIX (XEP-0369) support is still alpha level or non-existent. this is needed for a quality experience, with reactions, chat history, & as a technical advancement out of a bad shifty early legacy solution.

* Video. There are not a lot of video supporting clients. I think the spec is mostly ok for 1:1 video. But "Muji" multi-user video got demoed a decade ago & works but is more or less unimplemented. This is not cool. I think Muji also should probably be rebuilt anyways atop MIX.

* web integration. i'd like to be able to use my XMPP account online in a well-defined way. xmpp should start to define ways to make user accounts also OpenID Connect (OIDC) providers, & begin to define interoperation for webrtc & XMPP & the web to work together harmoniously.
which is perhaps why the email subject only got a single character

You're just using the wrong dynamic programming language. Don't get me wrong type checking, static or otherwise, is useful, but eventually you're going to have to throw in the towel and deal with truly hard problems like distributed systems, which in the end must be dynamic (you cannot safely assume that a node separated by time and space respects the same type system your node does).

I have a 20k LOC distributed system, 40k if you include all the libraries I've written for it, running in prod, written in a (typechecked) dynamic language, and it's fine. I had very few typing errors in dev, and one typing error that I pushed to prod. Even this had no discernible customer effect. I discovered it months later when I was checking over my logs understand logical errors. Currently all of the reported errors are race conditions on startup (and sporadic network errors). But it's fine. The system tolerates it, and restarts the failing modules, instead of being pedantic, and so instead of spending weeks debugging concurrent startup, I get a no-hassle fast booting system (which also means nonblocking bootup and thus higher customer availability during failure and restart). The other nice thing about dynamic systems, is that if they're not otherwise terrible, (logical) debugging is a breeze, because all types are inspectable and I don't have to worry about implementing observerability hooks for every single datatype. I can just look at the data as it moves through my system. And that also means that telemetry and logging with structured metadata just "happens", and is highly composable with no hassle.

I guess my biggest problem with static typing absolutism is that it leads to this attitude that code can be correct. It can't. Even if it's provably correct (in the mathematical sense), if your axioms are violated by your system then your system can wind up in an undefined state. You must plan for failure. And sometimes the most efficent/effective plan is "do nothing".
I'm saying "celebrities are getting hit now" pushed a lot of folks past that tipping point.

If a random person wins the lottery, no one blinks an eye. If Tom Hanks and the NBA win the lottery, people start wondering if a) it's more common than they thought to win the lottery or b) the lottery is rigged, because statistically celebs should have a low chance of winning it.
Yeah, at some point it just becomes a conversation.
My comment went on to say that you don't know ahead of time exactly which tests will prove useful. So you can't just skip writing them altogether. They key point is that if you have evidence ahead of time that a whole class of tests will be less useful than another class (because they will need several rewrites to catch a similar set of bugs) that fact should inform where you spend your time.

To go with the fire alarm analogy and exaggerate a little, it would work like this: you could attempt to install and maintain small disposable fire alarms in the refrigerator as well as every closet, drawer, and pillowcase. I'm not sure if these actually exist, but let's say they do. You then have to keep buying new ones since the internal batteries frequently run out. Or, you could deploy that type mainly in higher-value areas where they're particularly useful (near the stove), and otherwise put more time and money in complete room coverage from a few larger fire alarms that feature longer-lasting batteries. Given that you have an alarm for the bedroom as a whole, you absolutely shouldn't waste effort maintaining fire alarms in each pillowcase, and the reason is precisely that they won't ever be useful.

There are side benefits you mentioned to writing unit tests, of course, like helping you write the API initially. There are other ways to get a similar effect, though, and if those provide less benefit during refactoring but you still have to pay the cost of rewriting the tests, that also lowers their expected value.

To avoid misunderstanding, I also advocate a mixture of different types of tests. My comment is that based on the observation that unit tests depending on change-prone internal APIs tend to need more frequent rewrites, that fact should lower their expected value, and therefore affect how the mixture is allocated.
Kinda like the boy who cried wolf, we've heard this song and dance a bit too often. I for one will wait for actual independent reviews, and I predict those reviews won't be positive.

I'm not a web developer, so I'm curious to see if you guys could answer this for me: why are social media feeds so narrow on desktop now? Both Twitter and Reddit have feeds that are less than 1/3 the width of the screen. Is it because advertising feels more sparse if you pepper it along a long skinny string? Is it because they are using inflexible design frameworks for all devices? I seriously don't understand, I hate it, there's so much wasted space.

The market is big enough for multiple large Linux distributions (Redhat, SUSE, and Debian^WUbuntu*). The market continues to grow as more things transition to computers.

Quick scan of the website & the github. Did not find direct mentions of XMPP. Does this interop with other XMPP systems or is this based-on-XMPP but standalone? I would not adopt or recommend this, framed as it is as it's own thing.
1. You say the discounted cost for 1M queries per month with yearly commitment is $600 (= 1000 units, priced incrementally).
But according to your website (https://www.algolia.com/pricing/) 1000 units cost:
10 units free + (90 units x $0.83) + (400 units x $0.70) + (500 units x $0.61) = 659.70 !
This would be $659.70 versus the $600 you stated. Am I understanding something wrong?

2. What would be the discounted cost for 10M and 100M queries per month with yearly commitment?

more order flow means you can pool orders together more efficiently. i.e. several people in the same neighborhood order food from the same restaurant within a few minutes.
Latency is as bad as the slowest drive operation. This said, even two identical drives can have different performance due to things like error rates or heat differences.
There is a limit to reasonable accommodations. For instance, restaurants are not required to feed you if you cannot lift a fork.

I'd just not reply to everything to avoid a infinite loop but I like your last point:

> Most people at this point, practice these questions just like leetcode

This is a valid point and as you mentioned is true also for hard skills (eg. Algo prep with leet code). But at one point the question would be: would you rather hire someone that showed dedication for the job to the point that spent weeks/months to prepare leet code or possible other interview questions or someone that perhaps performed worst during the interview?

Most of the time you can always find out who is just memorizing everything by asking follow-up questions (both for technical and non technical questions) and as I guess you know (there's plenty info on the web) you can find books on how to crack any interview

I think actually a "let people figure it out" approach has been adopted and the countries that used it are quite successful. This was basically Sweden's stated policy, and Switzerland also stuck mostly to recommendations rather than rules.

What you see across the world is that the population's behaviour is generally ahead of whatever rules or recommendations governments are coming up with. People figure out the risks to themselves and others faster than governments do because the latter are incentivised (or believe they are incentivised) to take a safety über alles approach, and are very easily pushed around by "experts" and journalists, in ways that smaller groups aren't.

Eliminating the CDC - I don't think the CDC has been particularly useful in this event either. Frankly as far as I am concerned governments have made what is now obviously a perfectly normal and trivial virus drastically worse, to the extent that we'd be far better off as a world, and far healthier as a population, if governments had literally done nothing at all. But doing nothing is paradoxically the hardest thing for any government to do. The best way to bring about that outcome is thus to just clear out organisations and government agencies that would otherwise following a road of, "something must be done, this is something, therefore it must be done", which seems to explain a good 90% of the lockdown absurdities I see on a daily basis.
It’s just shorthand for stuff that we cannot detect but ordinary (electromagnetic) means. In theory everything ‘feels’ gravity and anything with mass contributes to it. The left-handed neutrino is unusual in that it experiences only gravity and the extremely weak (though far stronger than gravity) “weak nuclear force” (and their right-handed brethren, if they even exist, might not exist en experience that).

The “dark sector” is that 95% or so of the entire universe we infer must exist for either gravitational reasons (stronger gravity leads us to infer unseen mass, which we term “dark matter” though “transparent and apparently frictionless” would be a better term, or to infer unseen energy (dark energy that seems to be driving the accelerating rate of the universe).

Slavery, abundant natural resources, a commitment to not listening to 'sound economic policy' of its times (which would have had the colonies be strictly agrarian, shipping raw cotton to the English industry - look at Egypt and India for how well that worked out), genocide of the indigenous population, many years of exerting soft and hard power to control the continent, etc.

'Liberty or death' is a nice slogan, but it is in no way a core part of what made the US the most powerful empire in history.

This is similar to the Kon-Tiki theory that Thor Heyerdahl popularized, but has since been heavily criticized. Largely it implies that these people weren’t capable or skilled enough to make these voyages, that it happened by accident, and certainly has some racist undertones dismissing native Polynesian people’s knowledge and skills.

I spent some time as a teenager on a cultural exchange with a group of native Hawaiians and vividly remember being brought on some of their double hulled canoes and got to hear their master navigators explain a lot of their navigation techniques. It’s pretty mind blowing. I also remember a Hawaiian anthropologist talking about how a colleague in Central America had found some very old cave paintings depicting what seemed to be Haleakala.

It seems not at all surprising to me that ancient Polynesians were able to travel to the Americas.
Ah, the "myth" of Jeff Bezos. I only "met" him twice, in the hallways of PacMed, back when Amazon's workforce was so tiny compared to now.

I was at AWS, 2008-2014. In the early days, Bezos would frequently comment on AWS-related stuff, such as daily EC2 revenues, etc.

Occasionally, despite I wasn't an executive back then, I would also be one of the tens of email recipients that angry Amazon customers would use to shout their anger at the company (because my public facing role of tech evangelist, and my @simon Twitter handle).

I have to say, I don't think that Amazon's and Jeff's success has much to do with a "?" email, or the ":)" email I saw a few times. These are simply a shortcut for slightly longer sentences - "what do you say about this?", and "Nice work! :)".

Jeff's success, in my view, is an amazing capacity to hire excellent people, and being able to drive them to work crazy hours and feel like founders, despite not having share ownership in accordance to their work. Most of them, especially the early ones, are rich beyond any imagination. They could have been richer, sure... But they could also not.

Also, the organizational structure at Amazon, with every team having to provide APIs for their product, is also genius. AWS could have not happened without that.
I have to say, I'm not a fan of the new art style at all. Looking back at some of the older comics on his site, they really lose some of the charm and style in this new 3d format.

In my experience it's more the latter. Not only is it simpler (no need to maintain parallel ui implementations, easier to update, speed-up implementation time) to use a framework that "optimizes" layout for all devices, but it also increases consistency in experience across them.
With video and other rich media ? You will need hundreds of thousands or even millions of these disks.

YT alone adds 500hrs of video per min . That is at minimum 9000 TB / day (500 18TB disks/day - 180,000 disks a year) [1]

If YT is no more than say 1% of the public internet (Facebook is probably storing lot more , most of the data is not public though, Instagram is ) Then you are looking probably at 18 million disks a year without any backups and copies considered .
