Ask HN: Looking for an app developer as a cofounder to build a voice chat app
Hey folks, I'm looking for a mobile app developer and a marketer to join me as a cofounder to build a social voice chat app.

Has it ever happened to you that you was tired, lonely or maybe bored and you looked for someone to call, but you had no one to talk to, while you surely did had a lot of people on your contact list? I'm building an app to solve exactly this problem. The idea is to build an app that will allow users to meet new people with same interests through 1:1 audio calls. In this app users will choose topics that interests them like startup, dance, music, sports etc. Then whenever they will want, they will be able to instantly connect to a random person who shares same interests as them for a voice chat.
App will generate revenue through ads & subscription.

I have already built an MVP & done market validation with initial users. The response was quite good. Similar apps exist in the market like Maum (https://maum.app) & Dialup (https://dialup.com) I have some ideas to make a better version of them.

I'm a native android developer & i was developer of Vently app (https://play.google.com/store/apps/details?id=com.peerhose). I know some app marketing as well. I can make the android version of the app. I'm looking for a native or hybrid app developer to preferably make the iOS version.
I know the importance of marketing so I'm looking for a marketing guy as well to help us double down on marketing. If you do not officially consider yourself a marketer but you are really interested in doing marketing then you can join too. We will work on 80/20 principle. 80% marketing 20% developement.

Revenue and equity will be split equally between all members. Feel free to reach out if you are an app developer or a marketer.

Bonus: Getting first 5,000 users is on me!

To each their own, but I think the phrase “people on the left” may be better than “lefties”.

Lefties gives me the impression I know your opinion and political views well before the end of your thought. It weakens an argument that I actually agree with… even though I’m a lefty.

Why people use chrome is beyond me. Interacting with the internet through an advertising giant is just a huge nope.
Tinkering with microcontrollers is probably the most satisfying, because it really challenges you to understand exactly what is going on at all times, right down to the electrical level.

Developing for retro hardware can be fun too, for similar reasons.
So how is the enhancer mouse research different from the disease mouse research that you acknowledge often doesn't work?
I’ve implemented queuing simulators in the past, but two questions I’ve always been bugged by (which I feel like are easily answered if I ever took proper math courses…):

1. I don’t understand how you “know” you’re in the steady state, beyond looking at the graph — I’ve always just made it go like 10k steps to force it, but this seems needlessly wasteful. I imagine you could track the derivative but if it oscillates?

2. I don’t know how to verify if the distributions are poisson/exponential in reality, except by plotting

More relevant note, I’ve always been surprised by how little exists online on the subject, and how little code it actually requires; I forget the terms but multiple event classes, multiple agent, infinite buffer sim took maybe 100 LoC C# from stdlib. Maybe 60 LoC in python — probably 25% was just tracking the stats I wanted like wait time.

Biggest performance trick is that poison inter-arrival rate is exponential, and so you can generate all arrival times up front; then instead of simulating every second, you can just skip forward in time to when the events actually occur… so your sim scales on number of events occurring, rather than length of time simulated. Pretty sure you can even do arbitrarily length simulations in constant memory but never tried
They make it sound like it’s even less private than that, but don’t go into details.
That is an article which

1. Makes claims about performance
2. Provides no benchmarks

The only concrete answer to "why have swap if I have enough RAM" is "well, if you run out of RAM..."
I would argue it's the natural ruggedization of the existing tech (hololens platform). Integration with NV/Thermal and other tech is part of the scope so it only make sense. They had Gen 1 hololens prototypes in use for a while, just like 15 years or so ago they were using xbox 360 wired controllers to control unmanned assets. Eventually in field testing they'll break down or be damaged enough that they have to elevate the durability just for basic testing.

Looking at the kit it's clear it's not some crazy deviation. Hell just a modern NV/Thermal capable helmet and optics can be 70-100k worth of equipment without hololens, and look just as bulky.
We don't just have democracy vs. authoritarianism in a vaccuum, we have specific countries adopting specific ideologies with specific material starting conditions.

The UK used to be a massive colonial power that grabbed the world like it were an ice-cream cone, now they can barely respond to domestic crises. Yet they have become less authoritarian and conservative during the timeframe of their downfall. Currently, China has significant problems that could kill their future but they are currently demonstrating great innovation and scientific output. They have their own space station, are developing their own supply chains, have massive and ambitious infrastructure, TikTok is beating the Americans at their own game, and so on. Meanwhile, they have not seen a decrease in authoritarianism.

In fact, the current trend seems to illustrate that as economic growth stalls in the West, the population is turning to more authoritarian leaders. Perhaps our freedom was just a side-effect of fair weather, and we'll revert back once material conditions decrease?
It is well possible, but there are factors other than price in play. Fracking seems to be fairly dangerous for the environment, and current methods of lithium production have this problem as well (a lot of water is consumed in dry Bolivia to produce lithium).

In the future, we might be able to mine lithium from some sources that are now useless, but the environmental cost might be enormous.
Not quite the sam, but I’ve been using Kagi and they allow paying users to tweak search results by preferring, avoiding, or outright excluding whatever domains you like.

See: https://blog.kagi.com/kagi-features

Been really happy with those capabilities as they really help cut down on my exposure to low quality news/reporting.
OS kernel programming.
Modern Linux is too complicated for me, so I pick something smaller that can be easily understood by reading docs for a few hours: https://pdos.csail.mit.edu/6.828/2012/xv6.html

You'll see various folks publish their xv6 modifications on Github.

BTW, my daily work is mobile app dev (mostly Kotlin, sometimes Flutter). Totally unrelated, eh?
> geeks inside Google are much the same as geeks outside. They're just taking a paycheck

That's a huge difference. Between people willing to take blood money and those not.
You are either abusing the word "crash" or otherwise make a very dubious assertion here.
This paragraph is where I inferred this, especially the second portion I'm putting down in the second >

> Mohammed Al-Hamiri, one of the men featured in the film, told the Guardian that he wasn’t aware the film would be accessible internationally and only found out that it had been made available online after its showing at Sundance. “My life is already difficult but this film poses a serious threat to my life and that of my family,” said Al-Hamiri.

> *Another man said that he had explicitly told the film-maker that he did not want to be featured in the film but his wishes had been disregarded.* The film’s director Meg Smaker says that all the participants in the film signed consent documents and denied that the men expressed any fears in correspondence with her.

Personally, I am more or less ambivalent to the film currently as I've only heard about it due to the controversy and that Sam Harris covered it. Perhaps it's extremely meaningful and perhaps not, I haven't had time to process it.
There is absolutely no reason to use those over Ubuntu and many reasons not to use Arch in your critical server infrastructure, but Debian v. Ubuntu would be essentially half a dozen of these or 6 of those.
I’ve been pretty critical of Firebase on HN, perhaps too strongly. My experiences with it have all been the same, it goes like this:

Client has a new-ish codebase that was written by relatively inexperienced front end developers. They aren’t confident enough in the backend, and are attracted to Firebase because it lets them write everything from the front end.

Then they proceed to create the most convoluted DB model and a spaghetti backend that’s split between the front-end repo and various cloud functions.

In practical terms it’s been a nightmare every time, for me personally.
Would you interfere at the probable cost of a billion or more lives?

I’m not suggesting by any means what Russia is doing is justified and not horrific. I am suggesting that we are dealing with a country that has a nuclear arsenal that can do a significant amount of damage and may be willing to use it. That has to be considered.
This same kind of article gets played and replayed. Nothing new here. “Journalist” manufacturing outrage over something that’s been obviously true for Chrome’s whole lifetime.
> You cannot trade bonds without one

Yup.

In a previous life I worked in the vicinity of someone who only occasionally traded corporate bonds.

When that time of the month/quarter came up, they would do some limited research as best they could, but then ultimately the phone would be picked up to someone with a Bloomberg and the words "what does your Bloomberg say about X ?" uttered. They would only make their decision after that.

Bloomberg have built themselves a truly solid moat when it comes to fixed-income data.
Those bits about the price in Canada feel like clickbait: technically possible, but with caveats learned only after clicking, like perhaps it's only experienced by people with non-Canadian SIMs who decide to use a terrible roaming plan instead of something better? But with the links being dead, this is just speculation -- not writing in this format (of third-party dependencies filling in what appear to be major gaps) would've been helpful to avoid such speculation in case I'm entirely off-base and that truly is the price of data somewhere.
That is not the reason for the lawsuit. What the lawsuit claims is that Google is collecting information from users when they are using Chrome incognito mode.

I don't think a new incognito tab warns you about that.
Not all social media fuel conspiracy theories in the same way
But! all those are weak neurotoxics. We might have evolved to get "high" on consumming weak neurotoxics to avoid infections (some mammals, who also happen to have parasitic issues, like cats, do the same). Drug consumming seems to be highly evolutive, even if we do not need it with modern medicine.
The comment you replied to says

> if I choose to let it run at all, which I won't if I can avoid it.

It's not rare for people with a security/privacy background to only allow whitelisted sites to run JS.
> You will have a hard time finding people more critical of many of the actions of Google (the company) than Googlers

> Sounds like some people slipped up here and didn't pay attention in their mandatory communications training.

"You can say whatever you like inside the company, but never talk about it outside"
I think the hoped for end result is that every soldier wears one of these. If only a fraction of soldiers wears one, the ones wearing one will have to keep the others informed about the things they see that those without can’t see (and that includes telling them such things as “don’t shoot them. They’re ours” or “don’t go there. It’s a mine field”).

That’s a huge efficiency loss, even ignoring that the enemy will start targeting those wearing one.
Does it interact with pipewire any? Or prefers existing apis like jack?
> Absurdity. $180k per headset delivered? Did they mean $21.88mm?!

I don't know the details of the deal, but assuming it contains a clause "you cannot sell it to anyone else without our approval" it might be a realistic price when you know you're selling only 120k units of something you have to develop against interfaces with an equally small user- (and thus developer-) base ....
The nice thing is that you don't need to decide what to believe. You just keep doing experiments and, if well designed, they'll tell you what's true anyway. These animal model experiments are not intended to prove applicability to humans, they're intended to prove that you can take the next (tiny) step along the (extremely long) road to human applicability.
crash as in it's not recoverable using ssh - machine only responds to ping and needs a hard reset.
10+ years ago I also had problems getting hibernation to work. Then I read the Archlinux wiki on that topic and haven't had problems since.

It is working fine on Linux, you just have to set it up correctly.
From what I've read elsewhere the previous testing stage was using COTS hololens hardware which is not weatherproof or GI proof, and this was the first test of the production hardware, or at least the first version of the future production hardware, and it worked at least WRT being waterproof etc.

Its still early days for that program.

Note that this is not exactly the militaries first heads up display or helmet mounted display. This is "ancient" tech for helicopters and some ground vehicles with remote weapons systems. The new part of this program is the hardware is going to be dirt cheap in comparison (although still about $30K each) and its not just going to be for vehicle drivers / pilots / gunners but for infantry soldiers.
Option one:

Write a cloud formation / terraform template that involves O(1) machines and deploy 2000 identical copies.

Option two:

Write a template that deploys O(N = 2000) interdependent services across roughly 3-10x as many machines, and deploy one copy.

From what I can tell, you are arguing for option 2. It is strictly worse than option one. In addition to being more complex, it has a few nines less reliability, and costs 3-10x more for the hardware. The dev and CI hardware budgets is going to be 10x more because you can't test it on one machine, and it has bugs that only manifest at scale.

Source: I do this for a living, and have been on both sides of this fence. Option 1 typically has 5-6 nines (measured in chance a given customer sees a 10 second outage), option 2 never gets past 3-4 nines (measured in at least N% of customers are not seeing an outage).

The modern vs old technology debate has nothing to do with this tradeoff. If you want, you can build option 2 with EJB + CORBA on an IBM mainframe, and option 1 with rust and json on an exokernel FAAS.
Worse than killing the system, it slogs the system, locking it in a state where it doesn't function and doesn't recover.
> We plan to do more research on scalability, since column-based databases can’t grow as big as their NoSQL counterparts.

This one sentence makes me question this firm's expertise. "Column-based database" has a meaning, and Postgres definitely isn't one of them.
That's not programming, mate.
I'll take the bet. I pay you when it "never" does, and you pay me if it ever does. How does $1 and $100 sound?
> Al Franken also comes to mind.

Well... Al Franken is fine. He was rich and famous before he became a Senator, and he's still rich and famous now. Moreover, his successor was reelected, so the Senate seat hasn't changed parties.

Franken was a liability. Imagine him campaigning for women's rights. It just wouldn't work.

To be clear, though, it was Franken's own Democratic colleagues in the Senate who pressured him to resign. He didn't resign because Twitter told him to.
No, the issue is mass media. Private ownership of mass media just allows moguls to dictate their ideology to the mass. Slavery and holocaust are very, very good example of what happens once this ideology is dictated.

I haven't yet personally encountered self-taught folks who ascend to the niche of enterprise Java and excel at it. I'm sure it's possible, but I suspect it's a difficult path.

Java is manageable compared to C++, but a big nasty beast compared to Python, Ruby, Go, etc.

I think even in a down economy, a CS education is a good investment of your time. These days you can even do it online, and getting grounded in the fundamentals is a superpower when properly leveraged.
I occasionally use it for sites that uMatrix is a bit too aggressive with.

On Mobile Safari I use private browsing for my kid's youtube, so my recommendations aren't full of minecraft videos. But now that I think of it, it might be fun to teach youtube that people who watch minecraft videos are also interested in type theory and Edward Kmett videos.
> alleges the Silicon Valley giant misled the public about how much data it collects from users even when they're in its Chrome browser's "Incognito" private browsing mode.

That warning doesn't include Google tracking you as well.
Thats what the "theory of constraints" is in organizational/systems management.

Limit WIP!
No they don’t. East and South Asian family relationships can be quite fraught. People don’t talk about their feelings. Parents put tremendous pressure on their children to study in school. Then they pressure them to quickly get married and have kids right after school. I have met plenty of people from both India and China who have expressed a lot of alienation from their families.

It’s all economic pressure in the end.
Yeah, the parent did. It's in the same order of magnitude.
"Yet they have become less authoritarian"

Is this true for the UK proper? (Not the colonies, including Ireland.) Britain used to be quite a "lean state" domestically, while now being famous for having a lot of onerous laws micromanaging everything.

"now they can barely respond to domestic crises"

Interestingly, that was the case in the colonial era as well. Domestic problems in the UK were harder to address than wars on foreign continents. The Irish question was particularly stubborn. In 1914, shortly before the outbreak of WWI, there was actually a real risk of a civil war in Northern Ireland.
Do you have a limit? If he wants Lithuania and says he’ll use nukes do you say ‘well ok you’ve got nukes’ and sorry to everyone who lives there and just hand it over to him?

Also I just think ‘compromise’ is a ludicrous term to use - it’s not an informed business-like ‘compromise’ to allow someone to permanently subjugate you it’s submission.
The internal controversy seems to be that it doesn’t warn that your activity is still visible to Google (for ad targeting and conversion tracking). Which is arguably much less obvious.
That's a laughable claim.

And just 10 days ago:

Code security company SonarSource today published details on a severe vulnerability impacting Packagist, which could have been abused to mount supply chain attacks targeting the PHP community.

https://www.securityweek.com/critical-packagist-vulnerabilit...

And this source says PHP is the 2nd most vulnerable server-side language in the world.

There is more going on here. This is beyond just some pragmatic accounting on Musk's part.

He literally fell for Russian disinfo claiming that he was on some "Ukrainian hitlist": https://twitter.com/uamemesforces/status/1581068904021241857

The guy cannot do basic due diligence on easily verifiable crap spewed out on the platform that he is buying.
Is "QUANTUM" what we're calling TCP hijacking now? From the Fox-IT presentation, it sure seems like this attack is identical to Joncheray's '95 "Simple Active Attack on TCP", and, like, every TCP hijacking tfile written after that. If that's the case, the reason Suricata and Snort might not detect it is that nobody cares; it's an extraordinarily situational, second-order, and low-impact attack.
Change it to Debian or Alpine? Any VM under 512M I’d never deploy as RH-based.
If you're really confident that your SaaS application will only have that single workload (single table group-by) into perpetuity, it's a workable choice. But, that's a big bet against the reality of the diverse workloads required today in scale-up SaaS applications. Sure, you can stitch together specialized stores to make your own accidental distributed database for your app, but the simpler, more straight-forward and lower-latency alternative available. Yes, I'm a SingleStore employee, but it is worth considering the argument on its merit. It's also worth trying for free in production. The free tier for production is not time-bound, just capacity-bound.
And - what's the point? Websites that want to track you will track you anyway, there's a whole array of technologies that will let them to, and won't display anything to you if you don't run JS. Security objections are pointless, it's not 2001, JS is not anything new, and it's not at all a security risk, browsers are sandboxed and well isolated.
Is there anything like Firebase that lets you use SQL like schemas instead of their data store? That would fill a nice niche for some use cases I have been working with.
From the article: "Being closed-source, you don’t have the implicit assurance that Firebase will always be around (like Parse), nor can you reliably depend on a specific API version."

Firebase is amazing, but I'll never use it for anything that's meant to last more than a year. I don't trust the API to remain stable, and I _especially_ don't trust Google to keep it running for the long term.
My favorite subgenre is when my commit looks like:

“referring to the fact that the goggles generate light that's visible from thousands of feet”

Sounds like something that could be easily solved with a color filter, same way it works in red dot sights.

Also, there’s surprisingly little content in this article, and nothing of it is sourced.
