Oh. Dropping IO.inspect into the pipeline is embarrassingly obvious! I can't believe I didn't think to do that. I always used IO.inspect as a pretty printer during development but I guess I didn't think it would return/pass through its input. Thanks for pointing that out.

Deliveroo and Just Eat in Europe seems to have an explicit delivery fee shown at checkout (and distance based according to each restaurant).

Not sure if they take an extra fee on top of the "pre-delivery price" or how does it work.
Perhaps interesting parts will develop as a result of the placement. Tony Hsieh sort of did this in Vegas.
The delivery apps are going to be hard to compete with. Restaurants have to get a base of people willing g to deliver for them. And even more difficult, they'll have to make a platform that makes it easy for people to see what the menu is and order. Have you ever seen a restaurant website? Even one that does delivery? I'm incredibly skeptical that a co op would have the will, desire, or skillset needed from its members to succeed
As far as I know most of these delivery companies are loosing money themselves. Are there any sustainably profitable delivery services?

Ha, that's a good point, actually.

I suspect it's mostly, but not entirely true. In my circles the 'meet at a bar or other public place' circle is significantly wider than the 'meeting at someone's place' circle.

But perhaps even that looser circle is still good enough compared to the pre-lockdown situation (clubs being open, for one).

I'm sure HN has no shortage of ex-Uber engineers given how many people from their tech divisions they have let go of recently.

I am curious to hear what they think about this, in light of them being let go en masse, which in itself shines even more light on things that are outside of this discussion.

Was the company ever sustainably profitable? If so, which divisions/apps? When did they start becoming unprofitable?

Gouging restaurants who are already working with razor thin margins is really strange to me.

I am guessing they thought that as long as VCs kept pouring money in like gasoline, they could turn a blind eye to the fact that they have destabilized a fragile ecosystem that _a lot_ of people depend on (remember: knowing how to cook is an anomaly these days).

I'm guessing they didn't learn anything from Groupon.
Everybody knows that the third time is the right one!

I think the point stands even more, if they tried a rewrite before, they had gathered a lot of knowledge around rewriting a browser as well

Joe Armstrong, creator of Erlang, explained that his process to writing software worked like this:

- write it

- re-write it

- rewrite it again, but this time make it right

Yes, If you were jailbroken on the older version, and took steps to roll it back.

From the original piece: I don’t have a solution, but I hope my observations here might be interesting to some.

I have a partial solution: researchers "publish" papers to arXiv or similar, then "submit" them to the journal, which conducts peer review. The "journal" is a list of links to papers that it has accepted or verified.

That way, the paper is available to those who find it useful. If a researcher really thinks the peer reviewers are wrong, he/she can state why, and why they're leaving it up, despite the critiques. Peer-review reports can be kept anonymous but can also be appended to the paper, so that readers can decide for themselves whether the peer reviewers' comments are useful or accurate.

And with services like Backblaze offering cheap offsite backup, it's a no-brainer.

My home internet connection is 10:1 upload, but that's still 38Mbps up which is more than enough to backup several TB - sure, the initial backup will take a while, but it then keeps up with incremental changes without any issues.
Marketing can be a real struggle for engineers, they are often so focused on "proving" what works, they feel marketing or promotion somehow pollutes the purity of their invention. They are also REALLY bad at the aesthetics of design.

They are often dead wrong about this moral high-ground, good brand/marketing can be the difference between success and failure.

I've lived in this difficult world for decades, started out as a programmer, but the majority of my work is marketing and brand management. Iv'e worked with start-ups that 100% refuse all brand/marketing, and others that are completely misguided. But ive also worked with very successful companies that devote the time and money to marketing. After all what's the point of making something if no one uses it.

Car's sell because they have personality, it's not just about what's under the hood.
This is not at all the same. These restaurants are willingly and knowingly entering into and maintaining a businesses relationship with the delivery apps.

If they're unhappy with the cut that they get, they can either raise the prices they list on Doordash, or they can just unlist themselves (and the apps may create a listing for them, but then they still pay the restaurant the full menu price).

I don't understand the whole hearted support for a business that is asking consumers to inconvenience themselves to help maximize their profit margins. Where are all the people demanding that we all stop using credit cards to avoid the evil transaction surcharges from Visa?

I talked with someone in food manufacturing who mentioned the NIST guidelines for "did you short fill to your stated quantity" are more lax if you have variability in the size of the pieces. With well calibrated measurement devices, you could slightly short fill and but be totally legal. I'm looking for the specific formula they use to determine this, but my Google-fu is a bit lacking on this one.

I talked with another person who was at a meat packing plant. At the end of the manufacturing line for ground beef, there was a little machine which would extrude a tiny string of ground beef. The weight was precisely measured, a prescribed amount was added to get it to its required package weight, then it was packaged. He said the plant ran on ~3% profit margin, so they went quite far down the praeto of cost saving ideas.

I also know of an intern at Proctor & Gamble who noticed an overfilling of mouthwash. With the volumes they ran, they had annual savings of hundreds of thousands of dollars by better calibrating things.

In a related business, AirBNB straight-up lies about its service fees. I got a refund but it was much less than expected and they informed it was their service fees, after pressing them that that didn't add up to the service fee in my receipt, they admitted that there is also a service fee hidden in the part that is labelled as going to the host. So they take a chunk out from what I send them and then they also take a chunk out from what they claim to send the host and this matters both to the host and also to me since it affects how much can be refunded. I can't imagine itemizing a customer's receipt incorrectly like this is truly above-board with the law but what am I going to do?
Jail breaking is a deliberate and involved process, in some cases something that the manufacturer even allows for.

It’s not really the same as a random piece of JavaScript on a webpage jail breaking your phone. I think having a rootable device doesn’t inherently mean your device is insecure.
An idea has not any value. Someone doing something similar with what you think doesn't mean you can't succeed. What is important is the execution.

Look at Uber, there is still companies lunching to be their competitor, some are succeeding, some not.

If you want to work on this idea, forget about the competition. Meet with customers, are they willing to buy your product ? if yes, then you can succeed.

What is important is building something, meet with the market and iterate

Great promotional work! What's your side project?

Jokes aside, a large component of marketing is in aggregating opinion. The other half is the dark art we famously complain about.

Aggregating opinion at any level is hard work. And it's almost been elevated to a science now, so it has to be respected.

So to perform all that work to derive a conclusion which will most likely (given all that's known about the probability of start ups and success) prove you wrong, seems a perverse thing to do.

Masochistic, in fact.

I think it's easier to perform this work in the third person... It turns the dynamic on its head (like the schadenfreuder one might feel when working on a software project in the capicity of a QA tester). You're performing a clinical service.

But it takes some special effort to willingly put yourself through it...

I dunno.

And in the last quadrant, you can use non-raw threads like the Task or Parallel APIs and still have threading issues in C#.

I'm trying to learn Android and some libraries give zero indication of what thread your callbacks will be called on.

Maybe there's a convention somewhere that says "On Android, you can't assume anything about callbacks, so always assume you're on some anonymous worker thread and lock everything or dispatch to a thread you own"

But I have not come across it yet.

Your definition of "crazy" huge amount of data is pretty conservative. Your proposed solution would top out at 4TB, while most people I know who spinning up their own RAID at home are looking to store multiple tens of TB. For the cost of the solution you propose (4x 1TB @ $150/ea + $50 NVMe) you could set up an RAID-type solution with 32TB of raw capacity (4x 8TB @ $140/ea + $90 for PCie card and cables).
So, did it fit in the tunnel?
As a consumer of takeout, I would totally install and use such an app, assuming it was any good.

The restaurants would be incentivized to let all their customers know about it, which means they would be more than happy to have folders around etc. Not out of the goodness of their hearts, but because they would then not be held hostage to the other apps.

Your issue is building the app, getting restaurants to sign up in the first place and running the nextwork.

> It's going to go on until someone finally decouples the delivery from the discovery of the restaurants.

There's probably a business in setting up a really simple delivery network that just focuses on connecting delivery drivers/riders with restaurants. Restaurants could take orders on their website or whatever other platform they want and then send them to the delivery network.
Cool! Let's try this.

> 1. Write down the apps on your phone or computer that you use the most. If you want to bootstrap a profitable business, I recommend listing the apps you use for work.

Emacs, vim, xterm, tmux. (I use them all for work. 99% of the time, what you see on my screen is either Emacs, or an xterm running tmux and some instances of vim.)

On my phone, alarm clock. (I use it to get up for work)

> 2. Write down the one feature for each app that you use the most within that app.

In emacs and vim, probably self-insert-command or some basic motion commands.

In tmux, switching between windows and panes.

In xterm.. uh, just the fact that it's a terminal?

Alarm clock. I use it to wake me up in the morning.

> 3. Write down what slightly annoys you about that one feature

Nothing about the most used features above annoy me. Well, terminals annoy me but emulating terminals is the raison detre of a terminal emulator so I don't know if there's much you can do about it..

I also hate alarm clocks but I kinda need one to wake up.

> 4. Build the product around the one feature you feel you can cook up quickly and that will benefit your workflow

Looks like it wasn't that easy :(

Something tells me that picking the most used application and the most used feature in it most likely leads to the most solved problem that doesn't need to be solved again...

Currently, platform immunity means the platform can't be sued or criminally charged because a user hosts something for which the user can be. The proposed change would expose the operator of an editorial algorithm to liability for the algorithm recommending things that are already illegal.

I don't think the concern with rolling back platform immunity is government restrictions on free speech, exactly. In the US, the first amendment provides the same protections it always has. Instead, concerns include that the risk of liability will hamper innovation, that only companies with a lot of resources will be able to take the risk, and that companies will overreact with their own proactive censorship to stay well clear of areas with potential liability.

We've seen the latter with FOSTA/SESTA weakening platform immunity, which is arguably what its creators intended, but I suspect not what everyone in congress who voted for it expected.
It's fascinating to see people having such strong moral intuitions that restaurant people deserve to get paid for their work, while food delivery people do not.

That may be. Perhaps I don't understand libertarianism enough to evaluate the claim. upon reflection, it wasn't Locke I was thinking of anyway, but Hobbes; "Where there is no common power, there is no law; where no law, no injustice. Force and fraud are in war the two cardinal virtues. Justice and injustice are none of the faculties neither of the body nor mind."

Can you give an example of US government enforcing law not instantiated by the government? I'm having a hard time comprehending what you meant by "Government is simply the body for which we have ordained the authority to punish you for unlawful actions, it is not the body for which we have ordained to create the idea of what is and is not unlawful." Government processes create the laws under which a person may be found in need of punishment.

Sure, I agree that for a few the lock down is genuinely tough. Surely for a few others its an improvement over their previous circumstances. For the majority however, specially those that can actually afford VR, its nothing but an inconvenience, maybe a slight bump in anxiety brought about by a glimpse of chaos. Its that lack of perspective I have a problem with. There are people that actually are in danger, that have to go to work, because they are "essential", though apparently not essential enough to get paid, and the least the rest of us can do is stop bitching about being locked in a safe, comfortable place.
These things are orthogonal. You can RAID your NVMe storage, or not.

I think you're imagining a dedicated network storage appliance with spinning rust, which is one type of product that might use RAID. But really it's just a computer with some disks in it. You can use RAID in any computer with disks in it.
I think that it sets a different mentality if it is part of tools you use, you solve problems differently. It is of course possible to write highly concurrent code in traditional sequential languages and your examples proves that, but supercomputers are a special case with budgets for that. I'm talking about the general case, and I think the post I replied to also assumed that.

We have to give programmers, with different backgrounds & training, tools to write high performant code in their everyday job. Many of the tools we use today are not designed for that. We are stuck in a mental model 50 years old that is no longer true.

We can test the prediction that parachutes improve skydiver survival with a simple experiment. It would be an inhumane experiment, so in this case it is fair to assume the theory would be proven correct (but we can always test a similar prediction that parachutes prevent human-like objects from being destroyed, if you prefer).

With a global pandemic, it is in fact impossible to know, and anyone who claims otherwise is in fact a charlatan. That’s the key detail you’re missing here: The skydiver theory can be phrased as a “will” question, but this is always going to be a “would have” question. We can’t run an experiment to test any prediction - where’s the control Earth? If we can’t run an experiment, it is not science. Period.

Hm, I'm not sure i understand.

The 1tb NVMe Sabrent SSD on Amazon is $150: https://www.amazon.com/dp/B07LGF54XR/ref=cm_sw_r_other_apa_i...

You said you could put multiple in the PC so we can assume at least more than 1. So just for the SSDs, not including the NVM PCIe interface we are looking at $300 for 2TB.

In comparison for $100 you can get a 4TB WD red: https://www.amazon.com/dp/B083XVY99B/ref=cm_sw_r_other_apa_i...

That's a lot more $/GB than you could get with HDDs.

I have 4 2TB HDDs in a raid 5 array at home and all 4 disks didn't cost $300 and I have 6TB usable storage space.

So how is it cheaper to go with NVM SDD for home use?

It doesn’t make sense to describe Grubhub as “rent-seeking”, though. It’s not like they are sitting on some monopoly with power over the restaurants. Restaurants are free to simply not deal with delivery apps, the same way that all restaurants operated 10 or 15 years ago.

The overall premise of this article is good and needs to be said, but the author missed an opportunity by lumping traditional hardware RAID solutions with software solutions like ZFS. The general consensus I've seen from people spinning up large storage arrays in recent years is that the software solutions are far superior for many of the reasons the author mentions.
