Ask: Can an app survive without push notifications?
Hello HN, I've been working on an app that aims to make communication more meaningful by building a messaging platform that encourages you to communicate on your own time and strictly one on one. No friend requests. No push notifications. No endless feed of content from hundreds or thousands of "friends".

We launched our iOS app (share extension, and watch extension) this summer, but the product is still evolving so I'm trying to gather some opinions.

The app is called prsnly (http://apple.co/1iuuGGT ) currently out for iOS and we're working on finishing the web/mobile/android app. You can currently share images, text, video or voice notes within a thread and you can have multiple threads with one person at a time.

So, do you think I'm shooting myself in the foot sticking to a strict "no push notifications" policy? Most apps survive strictly because of push notifications, but I want to build something meaningful such that people want to use it because that's how they share with the people they love.

Any and all thoughts are welcome.

Help me make communication personal again!

I guess he was talking about higher walls around the (few) nuclear plants, not the whole country. That would not make the country "a jail where the only place I can see the ocean is from on top of a mountain".
Are you serious? "brew/apt-get these packages", many of which you'll probably have already, is so much better than the way it used to be (you'd have a tarball with a configure file if you were lucky, and if you were very lucky it would work).

Have any of the groupon competitors reached critical mass? I realize that a large number of "me-too" competitors were started when Groupon exploded, but it seems to me a "groupon that doesn't suck" could be a pretty good business.
Hi Clement, very neat dataviz ! How did you get the full history of all payments ? Is it available in the open ? What is 100mdeep btw ? Just a blogging site you are bootstraping or any plans to make a living out of it ? (We met a few months ago @ ToucanToco...)
If I was consulting on a flat fee, that's the advice - virtualize to the most compatible OS - I'd typically offer because it is the most likely to deliver the most business value over the long run. On the other hand, if I was charging by the hour, I'd spend my time and the customer's dollars creating a one-off installation that is likely to break and need future $upport when components change.

On the third hand, if the task was trivial, then there would be no reason to complain about a lack of bespoke Windows instructions, since they would almost write themselves. Of course if bespoke Windows instructions are non-trivial, then obviously it's hard to see merit in the complaint.

No, if Mattermost and Gitlab were linked, the AGPL restrictions would apply to the Gitlab code, even if it's MIT licensed. Otherwise, anyone would just be able to make a MIT-licensed wrapper around an AGPL project, allowing indirect linking between proprietary code and AGPL.

What Mattermost apparently did was compile their own code (under the name "Gitlab Mattermost"), and distribute that compiled version under MIT, so there's no AGPL in the Gitlab distribution.
> Restaurants can use the service whenever they expect to have empty tables, allowing to still profit for them, but with a reduced profit margin.

Businesses receive 20-25% of retail price when they take a groupon deal, so you'd need a profit margin >75% to even entertain that idea. Also it cannibalises some of your existing customers, converting your 75%+ profit margin customers into near zero or loss customers. I'd leave the tables empty.
Looks good! One small typo: On the Pricing page https://about.gitlab.com/pricing/, instead of " Next-business day support" it should be "Next business day support".
> Ironically, many people hated the movie because they didn't recognize that it was satirizing the (apparently) pro-military book.

It was actually intended as (per Verhoeven) a satire of right-wing, fascists elements perceived in modern American culture that directly associated them with Nazi propaganda; the movie was largely written independently of the book, with rights to the book secured later after superficial similarity between some elements of the movie and the book were pointed out, at which point names, etc., from the book were added. Verhoeven says he only read two chapters of the book.

The film was a satire, but not of the book.

Why don't they wait for the situation to stabilize there for a few years before they start replanting crops that are just as likely to fail or be destroyed? The war isn't even over.

If they're planting the crops elsewhere just to get something going now that is not in storage, to replant later in Syria, then it makes sense.

"The time frame in question when dealing with radioactive waste ranges from 10,000 to 1,000,000 years"

As I noted below, a long half-life implies less radiation, by definition. "Infinite half-life" = "not radioactive at all".

Anyone who tries to use a long half-life as a scare tactic is either lacking in knowledge or selling something.
> You do understand, right, that your standards and expectations for disclosure have nothing to do with any recognized standard for journalistic ethics, right?

Pulitzer disagrees with you. From http://pulitzercenter.org/about-us/ethics-and-standards-poli...

CONFLICTS OF INTEREST

Normal activities - outside work, investments, political activism - pose special problems for journalists. Often, it's best to avoid activities that might interfere with your ability to function as a journalist. Alternatively, you may be precluded from working on certain topics for the Pulitzer Center if you're personally involved.

A third alternative is public disclosure of any information that a site user might find relevant in understanding the content. Someone who is writing about a relative would need to disclose the relationship. A guest contributor writing about politics would need to disclose if he is associated with a candidate, and any employment or other financial relationship that could be viewed as related to the topic being reported.

Full disclosure of relevant information is standard practice for the Pulitzer Center - a necessary step but not always sufficient when a potential conflict of interest exists.

I like to write my code to assume that it will run the same on dev and prod, but then precompile/minify prod code as part of the deployment.

That is, I like to set it up like you say, but then not rely on it in production. Mainly because I want as few moving parts as possible on prod (especially if it means I don't need dev tools/libs on the production server).

Exactly this. It stopped being a good way to discover local places you may not have heard of and instead became a way to shove cheaply mass produced junk or freely mass produced digital junk in to eveyone's mailbox.
In particular I suspect there's very few gains that can be made for wireless communications. My contention is that there exists a information-theoretic lower bound on the amount of energy it takes to transmit a given amount of information a given distance. Like a heat engine, at some point you can no longer make generational improvements in efficiency. You get asymptotically closer to the bound, you can't ever beat it. And wireless power tends to dominate the power budget of anything that uses it.

High-bandwidth signals require more power to travel a given distance, low-bandwidth signals go farther on less power but transmit less information. Intuitively this is why you can go worldwide with CW (Morse code) on just a few watts of power, while a SSB signal on the same frequency doesn't go far at all. But I think you can mathematically support this by playing with the bandwidth+power terms of the Shannon-Hartley theorem.

If we want to transmit a given amount of data per time unit, there are two natural extremes. We can either transmit it at the average data rate necessary, or we can race-to-sleep by blasting it out as fast as possible. I'm not sure which is more efficient given that SNR is inside the log2 of the S-H theorem, it depends on the relationship between SNR and bandwidth as you spread a given quantity of RF power thinner and thinner. Based on the log2 I would think this is an inverse-square kind of thing, making it an equivalent tradeoff.

Showerthoughts: because of the Inverse Square Law, it's probably more efficient to make a mesh of multiple small hops than a single long shot. As the spacing of the mesh decreases to zero, you end up with a wire.

Also, check out the ESP8266 chip, it doesn't have a BTLE onboard but it does handle the "SOC with low-power wifi" thing.

> Did you consider that perhaps gators are not my audience?

Moreover, did he consider that sometimes journalists should say things that the audience does not reflexively and unthinkingly agree with?

I mean, jeez, I disagree with you approximately all of the time, but that's because I'm right and you're wrong--err, because we come at this from different places and have different priors, that doesn't mean you're hisssssss anti-audience hissssssss.

The fixation on media telling them what they want to hear, regardless of any sort of truth or honesty behind it, and the drive to retaliate against people with the temerity to have an opinion that is not completely complimentary to straight white men is probably the worst part of this whole cancerous mess.
this is the biggest issues, depending on the cloud ip block you can get banned.
Though it would be great if you could, don't use blackduck as the measuring stick. (Used to be Ohloh now) Blackduck is not a full view into the current state of open source and free software. I gave up on trying to keep my projects updated not long after the transition from Ohloh to Blackduck.

Apache is suggested as a free-software-compatible alternative to GPL v3 by RMS himself. In the past 15 years of contributing to open-source/free code projects, Apache is the longest standing license that over and over people have recommended. It is an intense license, but it covers the bases legally, whereas others do not. Still- I've used GPL, MIT, and BSD in the past- just learn about the pros and cons and choose what you think you should use, though.

It's possible that it gets cheaper in winter. My wife and I did exactly this trip but around christmas-time and it was fantastic. IIRC we paid a similar price but for the little cabin instead of the chair car.

A lot of American friends were surprised we were doing this - they had this idea that it would be uncomfortable and boring. They just couldn't have been more wrong. Between the comfortable room-ette things, often very friendly and varied fellow travellers, surprisingly tasty food and absolutely amazing scenery, it's a fond memory.

Of course, we scheduled in plenty of time - if you need to be somewhere punctually, Amtrak is not really your best bet.
I used a Symbolics 3600 much more memory, 4MWords IIRC. My own 3640 has 4MWord. A word was 36 bits wide.

Sure not: you could use a 3600 with 20 MB RAM and 150 MB virtual memory.

From what I can tell, the dev team of Mattermost is essentially releasing two versions: you can get the original source under the AGPL, or a compiled version under MIT (called Gitlab Mattermost). Since they own the copyright, they don't need to abide by the AGPL when producing the compiled version.

An interesting side effect is that if you were able to decompile that version, you could in theory have a MIT license to the Mattermost source, avoiding the AGPL.

There is no equivocation in my post whatsoever. I was responding to what I saw as a lazy "sound bite" post that was using incorrect information to make a stronger point than it had. There was no judgement about the actions of VW, no downplaying of the seriousness of NOx pollution. Those issues are not relevant to the question of whether the facts presented are materially correct, which they were not.

I will address one thing, though:

> Anything over the mandated limit is a health risk, and equivocating over how much is like asking whether you'd want 3 years, or 10 years shaved off your life expectancy.

That is not equivocating. Also, pollution exists on a continuous scale. Saying everything over the limit is equivalently "bad" and everything under the limit is equivalently "good" is ignoring that. There is a big difference in effect between, say, twice the limit and 40 times the limit.

"Early insiders are still fine, of course. Groupon co-founder Eric Lefkofsky and his affiliated entities took nearly $400 million off the table well before the IPO." from https://venturebeat.com/2012/06/01/groupon-investors-race-fo...

This article doesn't tell the whole story. As a user of Groupon Panama, I can tell you that they face stiff competition here from a Groupon clone, ofertasimple. I think they're exiting because it was a small market to begin with and they haven't been able to win it. Many people, including myself, find the competing service superior.

Well, they basically did.

"Altogether, $946.8 million, or roughly 86% of the funds raised across the three investments, was paid out to Groupon directors, officers and stockholders. Just $151.4 million was retained by the company to use as working capital and for general corporate purposes."

In Denmark we have http://downtown.dk, they managed to get traction here before Groupon, so they have had most of the market, however it seems like Groupon have been eating parts of their business recently.

As an aside Groupon seems to be 100% https, where downtown is only partly https :(
An Introduction to JavaScript ES6 Arrow Functions
I agree. Personally, I'm not sure my retention on things I've tried has been great for the businesses doing the offering. Things seem to end up a few different ways:

1) I love what they're offering, but I want to do their thing somewhere else, so another business gets the benefit.

2) I don't like what they're offering, oh well, gave it a try

3) I like what they're offering and they're in the right place for me to continue doing business with them

#1 is the hardest for businesses, and I admit to engaging in a fair amount of "Groupon tourism", where I'll go a little out of my way to try something just because I got it for cheap on Groupon.

For #2, sometimes there's a reason why places aren't doing well and turn to Groupon to try to boost sales, sometimes it's just a bad fit for me as a consumer. For example, I just used a Groupon for a local new Mexican place in my area. Turns out the reason their gorgeous restaurant is mostly empty is because the food sucks. There's a Mexican place down the road from them with low budget hand-made booths that's exploding with customers, the difference is that their food is good.

I'd say I probably stick with less than 10% of the new places I find through Groupon. I'd probably be willing to pay more to try new things...but not a whole lot more. As a consumer I have to change my basic behavior patterns and maybe travel out of my way to try something new, I feel like I'm meeting the place halfway. Sometimes I have to travel someplace I've never been before, and after getting there I'll know if it's reasonable to continue coming out there. The horse lesson I took I enjoyed, but it's also an hour of hard driving to get there, while I live right on the edge of plentiful horse country. Now I know I had fun taking a lesson, I might give a go at one of the local places, but I'll probably not return to the place I used the Groupon with.

There's also places, like a zipline center I Grouponed at. It was cool, I'll return. But it's not like it's an every week kind of place. So I think businesses also have to consider their model. I wouldn't have tried it without the Groupon, but it acted more like an advertisement would.

I also went to a high-speed gokart center on a Groupon. Turns out they already have lots of business, but it's all dedicated racers who knew what they were doing. When I went there I had to sit through a half hour of safety training videos, and when I got on the track it was terrifying because everybody else was hardcore and very aggressive. It could have been fun if everybody wasn't taking it so seriously, or they bundled all the Grouponers into a beginner league or something. So I don't think it worked as an expansion of their basic business.

I think business issues with Groupon are more complicated than people give credit for.
It depends on your definition. API is application programming interface, which means that if your product doesn't intend for it's internals to be called or it is a DSL, etc. you don't necessarily need to have formal API docs- you just need usage docs. If it is a C, C++, Java library, then yes, you probably want API docs/Javadocs.

Silly question: How does CloudFlare make any money?

Any random can put any site behind their (very fully featured) free services and get free CDN, free antimalware, and free $other_services, with no seeming limits as to the amount of traffic you get. This has no impact on the target site. There are no ads or any other such. Their enterprise products only offer a few more features at a massive cost hike.

How are the bandwidth costs not eating them alive, and how are the free users being subsidized?

This is not appropriate post about the 8.0 announcement. But I'll give you this: any project with a CLA and a dual-version open / proprietary thing is not 100% in-line with ideal Open Source or Free Software values. I'll also give GitLab this: they've gone further than most would expect when pushed and have made sure their JavaScript is all Free/Libre/Open, and good for them. They could be better and they could be worse.
