Here's a question from an old Redis hater (the note is important, since my question is going to be slightly biased - I disagree with a lot of core decisions behind Redis):

How is this going to be different from Kafka? And I don't mean implementation details, because these are always fun read. Kafka is on the market for ~7 years, during which it has proven to be oh-so-fast and pretty durable.

Oh, and while I'm at it. Here's another problem Redis geniousl added: a GIL. GIL is a great idea, but comes with huge tradeoffs. David Beazley spent years showing how many tricks you can play upon yourself with GIL.

So ... now you have Streams and GIL together. And you already have dicts (you call them hashmaps). I have a feeling you're trying to implement Python. If so, it's done. But come on, 3.6 is cool. And we're kinda solving the GIL problem. With PyPy. Which will blow your mind.

net/RPC is a rpc implementation in the go standard library, which uses gob for serialization.

gRPC is a protocol and set of libraries for cross-language rpc based on protobuffs. Also doing a lot of codegen for you, like generating clients.

Ditto. I don't usually use anything except the refrigerator--and even many "regular" hotels these days seem to have emptied the minibar and left the mini-fridge--but they usually also have sofas, etc. and generally room to stretch out. I often find it preferable to usual hotel amenities that I mostly don't use.
I think that "certain temperature" varies for different people, or even over time for any particular person. When I was a child the cold killed me. A few weeks ago, the highs were in the mid-teens all week around here, and I found myself completely comfortable in jeans, a sweater, hat, gloves, and a coat while outside doing farm work. The big problem at those temperatures is working up a sweat when wearing clothes that don't immediately wick it away from the body. That gets very cold quickly.

Wouldn't it be better if we adopt the position that unbreakable crypto is a basic human right? Every time we hear about government demands for backdoors, we technies, cryptographers, thought-leaders, and journalists respond that backdoors are a security risk and can't be implemented safely. I feel this invites endless counter-arguments and new proposals by the authoritarian parts of government. We've been playing this game forever -- as far back as the Clipper Chip in early 1990s -- and it never seems to end.

Maybe we should take the high road: the time has come that unbreakable crypto is to be considered a basic human right; the same as free speech, freedom of thought, or freedom of religion. In this digital age, a lot of those other rights can't be guaranteed without strong crypto. Whenever any mention of backdooring, weakening, disabling, preventing encrypted communication comes up, our reply should be, "no, you can't do that because crypto is a human right, the same as free speech, and is necessary to protect other fundamental rights".

I've always balanced my usage between Abnb and hotels. As hotels fulfilling the role of resort vacation or business trip overnight stay. Weekend trips or city crawling vacation I usually stay with Airbnb. I relate to your statement that you never know what expects you.

The Manchester and Bataclan incidents are perfect examples. That's the whole point of terrorism. The groups are not effective enough to influence who they want without fear tacits. They're going to target large groups of people, and events tend to do that.

The situation of the Bataclan, the emergency services does need to know whats going on inside, and at multiple points of the building. For Manchester, they needed to know what exit was being targeted, and which other ones that popped up as well (there could have been more than one attacker)

When doing extended traveling mixing hotels and AirBNBs is great because you can get laundry done and make your own meals when you want.

Your state park would indicate "no vehicles beyond this point" and I assume if anyone starting driving on the hiking trail they'd be asked to follow the rules or leave.

Consider the fact that you just joined the company, and are likely unaware of many complexities, dependencies, and edge cases that the code must account for. I suggest working with the code a bit longer before you make such bold proclamations as to its quality.

Also consider your teammates built that code. How do you think they felt when you told them it needs a whole refactoring? Since you cannot refactor it in secret, you would need to get your manager’s approval to take on such a project. He is going to ask your teammates, who built the code and whom he’s known longer than you, for their opinions. So it’s important to have their support in refactoring.

It seems like a needless risk. You have a low chance of success (first, convincing your manager, and second, successfully refactoring the code), but a high chance of loss (alienating your teammates).
One of the listed items under the ACCC's guide for "major" problems is: "it is significantly different from the sample or description".

Quantum Poetics: Why physics can’t get rid of metaphor

> These are implementation details tied to low funding and car oriented infrastructure

No, it’s fundamental to the technology. The deadweight cost of the driver mandates a minimum economic size. If you have a big bus, you need a route with lots of people. My long and skinny Cupertino —> Mountain View 6AM/9PM will ne inefficient, or the system will be inefficient—no other options with big buses.

A derogatory comparison to Uber is appropriate; it’s amortising the same driver across fewer people. Comparing busses to carpooling is not; I get from and to my precise destination, minimal walking or transferring, and take up no deadweight driver. If you want, think of carpooling as mutualised modularised busses.
Agreeing with other comments, that seems like a problem with warrants in general, not with some supposed technology. If cops can get a warrant to raid anyone's house then of course they'd be able to get a warrant to raid anyone's phone in this situation. The solution to that issue would be to fix how warrants are granted to make them less prone to abuse. But that seems like an entirely different debate.
I agree I was just trying to understand it further. I've always thought the idea of modeling the world was really interesting but it's always been a tad abstract to me so I was trying to get a little insight into it.
Branchless banking using your cellphone number as your account number is set to become a thing.
Also streaming that you can't do with regular REST, so think about push notification and the like.

One of the biggest advantage imo is the contract between the client and the server, both are always in sync about what to send / receive.

I've seen many times things break because x,y,x added a field or change a type that the server / client couldn't understand.
The problem is that whether you're an "early bird" or "night owl" is a matter of biology, not how early or late you choose to wake up (https://www.livescience.com/16334-night-owls-early-birds-sle...).

Because of the way school and work schedules are structured, you're right that it can give you an edge to be a morning person (I'm fortunate enough to be one). However, waking up early doesn't make a night owl an early bird - it makes them tired. The fact that people are split along these lines makes it questionable to enforce schedules that suit part of the population but leave the remainder strained and underutilized.
Just to back up my statement above with actual ACCC advice:

"it has a problem that would have stopped someone from buying it if they’d known about it" is considered a "major" problem with the product.

> We need a new etiquette and I'm not sure our culture can support one right now.

Can't or won't?

I think it's interesting that those with the poorest etiquette are actually older generations who have abandoned it almost entirely simply because portions of it became outdated.

The younger generations who actually understand all of the new technology, social issues surrounding LGBTQ..., and the #MeToo banner wavers are, to me, the best people to establish new etiquette and to push for it's adoption.

Etiquette is about decency and treating each other with respect and fairness. What better way to make your mark on history than to be the generation who chose mutual respect and fairness over greed and self indulgence.
There are definitely cases for both. JSON is definitely easier to consume as a human (so for debugging).

gRPC was born out of Google's Stubby rpc system[0], which is used heavily for communicating between different jobs. If you are going to stand up a lot of different services that are going to talk, it provides a lot of advantages that you don't get with JSON. For large companies that use multiple program languages, this is really nice, as proto3 and GRPC have code generators for a slew of different languages.

There are a lot of other niceties that are useful in gRPC that you don't get with JSON (like streaming data).

> emotional, irrational day trading among people who can least afford it

This is completely untrue on the face of it:

"Unless you have an equity balance of at least $25,000 in your account, your Robinhood Instant or Robinhood Gold account is limited to no more than three day trades in a sliding five trading day window [emphasis mine]. Exceeding the three day trade limit will restrict your account from placing further day trades for 90 days." [1]

As someone who actually day trades, being able to do 3 trades every 5 days is completely useless.

As an aside, sort of disappointed this is the top-rated comment when the evidence against this claim could be found using ~1 minute of Googling.

That happens in angel/pre-seed/seed rounds. They're usually much smaller contributions and are much easier to do because you're not giving out equity, you're technically taking debt which will convert to equity on the next equity financing round (usually series A).

Also after an equity round, investors typically have pro-rata rights so you can't take any money without getting their permission and ask them if they'd like to contribute more to maintain their share.
I can't imagine a scenario in which I'd prefer an AirBnB for business travel. But here's a scenario that AirBnB was a perfect fit. My daughter is a cheerleader and we sometimes have traveling competitions. There are some families on her team which we're friends with. Rather than everyone getting a hotel room we rented an entire house on AirBnB. Each family got their own room, the kids got to enjoy being together, and we had a default location to just waste time watching TV or whatever all together between competition events. We ended up cooking out at our AirBnB location. It was really great for this more casual travel experience.

Ask HN: Advice on building an app POC by non-technical person?
Hi everyone! I am non-technical (by non-technical I mean no coding skills) who has an idea for an app business. It’s like Tinder mixed with Meet-up for people who are looking to do activities with people (strangers). I am currently in the idea validation phase.

I have run a few facebook campaigns using a landing page and have shared mockups with family and friends for their feedback. Feedback has been positive. I’ts hard to get a sense as to whether people would actually use the app (since I am not selling a product, I can’t get them to pre-purchase).

Before moving forward with the project and recruiting a technical founder, I would like to validate the idea further to increase the likelihood that I am solving a real problem that people want solved. I would like to build a working proof of concept to see if early adopters would be attracted to the project and to receive feedback on critical features.

My thought process is that if I can validate the idea and show early traction, then I will be in a better position to recruit a high quality technical founder. For a non-technical person, I thought the following proof of concepts might work:

A low fidelity app built on a no-code app builder like Bubble, Goodbarber, Shoutem, Appery.io, etc.
An MVP app in which the development is outsourced (freelancer, overseas dev shop)
A simple web app using a pre-built Wordpress theme

Some basic issues include:

At first glance, with a no-code app builder, i’m not sure I can build a “good enough” app to receive meaningful user feedback on the idea or core features.

To develop an MVP app is expensive (online i’ve seen ranges of $5,000 to $15,000) and I can’t successfully project manage the app development given my lack of technical expertise.

A simple web app that I construct may not provide an accurate user experience that I envision to be critical to my app’s success.

What method should I pursue next as a proof of concept to further test the idea?
> Also streaming that you can't do with regular REST

Nothing about the REST architectural style prohibits a resource (or, rather, a particular resource representation) from being a stream.
