langitbiru··on New Snap Spectacles Feature Augmented Reality Display
Conversation helper. Imagine you talk to a person. It can give you a list of ice breakers to open up the conversation based on the person's appearance and surroundings.

It can alert you whether the person is not comfortable or very attracted to you. Some people like to miss these subtle cues.

You can combine this AR technology with Deep Learning technology such as Pose Tracker.

langitbiru··on Launch HN: YSplit (YC W19) – Automatically split and pay any bill
Congratulations! By coincidence, your startup reminds me of the use case of smart contracts. I always tell people that smart contracts are cool because you can program money however you like. One of the examples is payment splitter.

Recently, I coded up the payment splitter smart contract.

https://mamba.black/documentation/payment-splitter/

Yours is bill splitter. But technically, you can code up the bill splitter as a smart contract too.

That's all. I wish you success. Who knows my story is useful for you. I don't know. Maybe a few years later, you want to expand your service to cryptocurrencies. :)

langitbiru··on Fierce Nerds
> There has never been a better time to be a nerd. In the past century we've seen a continuous transfer of power from dealmakers to technicians — from the charismatic to the competent

What happens if a nerd learns how to be charismatic? It's a winning combo, I guess.

langitbiru··on Ask HN: What are some tools / libraries you built yourself?
Mamba (https://mamba.black). It's a blockchain development framework. It's like Ruby on Rails but for smart contracts development.

The story goes like this....

I was writing a book called "Hands-on Blockchain for Python Developers" in 2018. At that time, the only Pythonic blockchain development framework which supported web3.py and Vyper (a smart contract language that has syntax similar to Python) was Populus. A week after my book was published, Populus was killed by its developer.

So I decided to create one to support Vyper language.

However, I need to tell you that there is another blockchain framework that supports Vyper and web3.py which is more popular than my framework. It's Brownie-eth. If this tool existed in the first place, I wouldn't create Mamba. But hey, such is life. Now I have to raise my child, Mamba. ;)

langitbiru··on Azar, a Korean Chatroulette-style dating app quietly taking over the world
I'm thinking of building a decentralized dating app (without crypto). It's something like WordPress but for dating. People can host it on-premise. You can say it's like white-labelling dating app. So each community (church, gym, yoga studio, etc) can have their own dating app and don't have to live on the mercy of Match.com. This way, we can keep Match.com in check.

From the article above:

"Match, which owns another popular dating app and Bumble competitor, Tinder, is suing Bumble for violating two patents and for allegedly stealing trade secrets.

It was a lawsuit made all the more intriguing considering Match wants to acquire Bumble;"

langitbiru··on Why do we buy into the 'cult' of overwork?
Entrepreneurship, taking care your parents, raising kids, passion (writing novels), working out, and so on.
langitbiru··on Ask HN: How to attract perm Snr Engs when the contract market is so lucrative?
YES. Part-time jobs are getting more popular. Some people are looking for works that give them more free time. Look at GumRoad which offers part-time jobs with competitive salary ($100 - $150 per hour).
langitbiru··on A Hybrid Approach to Work
Shameless promotion: https://parttime.careers

I plan to add a feature where you can advertise yourself on this website that you are looking for part-time jobs. How many hours are you willing to work. What skills do you have. You will be able to login using GitHub account.

Part-time jobs are getting more popular. Anecdotal case: https://twitter.com/zachcodes/status/1390033250148655111

langitbiru··on No ID, no vaccines for Indonesia’s invisible people
> Also marriage between members of different religions is not possible.

You can. But it's hard. So basically the main requirement of marriage is it must be performed in a religious ceremony. You cannot have a pure civil marriage in Indonesia. So the thing is.... the clerics, the priests are not fond of mixed-marriages. But there are marriages between Buddhist and Catholic, Christian and Catholic, Muslim and Christian. I'm an Indonesian.

Also, there is a loop-hole. You get married overseas and register it in an Indonesian embassy.

langitbiru··on Ask HN: How many projects do you work on at a time?
> sounds like a lot for me

It does. If you're wondering why I have so many projects, the answer is complicated. One thing leads to another. Basically, I'm throwing many darts and see which one is the most potential. Right now, I don't know for sure. You can say I'm doing breadth-first search. Once I found the winner, I would reduce my involvement on other projects.

> Are they bringing in revenue?

PredictSalary: it got around 600 users. No revenue yet.

SwanLove: the product is still weak. It's still a long way to go. I think it needs investment. I applied to YC with this idea. But I think I failed. :)

Mamba: this is to keep my blockchain programming skills sharp. Right now, the blockchain space is on fire. So I think it's a good idea to have something as portfolio in blockchain. This is an open source project. No revenue.

ParttimeCareers: actually, right now I treat it as a bookmark for part-time jobs. I only update it once per month. No revenue yet.

Pembangun: I launched this forum a couple of days ago. I need to build an audience. You know, someone said that hackers always forgot to build the channel. Hackers only care about developing product. I try to avoid that mistake. No revenue yet.

langitbiru··on Ask HN: How many projects do you work on at a time?
Too many!

1. PredictSalary (https://predictsalary.com) A browser extension that can predict the salary range of job opportunities.

2. SwanLove (https://swan.love) A dating web app based on Linkedin profiles. Later, I want to expand to other social medias, such as GitHub, Strava, etc. Then I want to decentralize it so you can install it like GitLab or WordPress.

3. Mamba (https://mamba.black) A blockchain development framework.

4. ParttimeCareers (https://parttime.careers) A part-time remote job boards.

5. Pembangun (https://pembangun.net) A forum for Indonesian indie hackers (inspired by https://www.indiehackers.com/).

In the future, these projects will help each other. PredictSalary can be combined with ParttimeCareers. I already combined SwanLove with Pembangun. You can show your SwanLove account in the user profile in the forum Pembangun to show you are open to dating. This is to show you can add dating to any website while maintaining the main value in the website. Using Mamba, I will turn the forum Pembangun into DAO (Decentralized Autonomous Organization). That's not sci-fi enough for you? I can combine Mamba with SwanLove to create a decentralized dating application! You send "like" to people in a smart contract. You can also create a bounty in a smart contract for people who can introduce a wonderful person to you. :)

langitbiru··on We were promised Strong AI, but instead we got metadata analysis
I'm building a dating app, SwanLove (https://swan.love). It's still in MVP mode and centralized mode.

I'm thinking of pivoting into this kind of business model: B2B. So I make my dating app something like GitLab or WordPress. You can install it and host it yourself. You pay me every month if your users exceeds 100.

Say, you are a priest or a gym owner. You have a community. You want your people in the community (church, gym) to have a chance to find a romantic partner inside the community. Anyone who wants to register in your dating app needs to be a member of your community first (church, gym). This way, I don't even hold the data (avoiding becoming a honeypot for hackers). I just want the money (in an ethical way).

What do you think? Is this ethical business model for a dating startup?

For the centralized dating app, maybe the subscription package can help them foster their relationship. I don't know. I'm still thinking about it.

Or you can create a bounty in the dating app for someone who can introduce a wonderful person to you. Then if you get married, the dating startup gets a cut from the bounty. The problem is how you verify whether people get married or not. Can we do something like bootcamps offering ISA that can access their students' tax records?

langitbiru··on College as a Marriage Market
That already happened, no?

Some men pretend to care about yoga and veganism just to approach women. You can see some memes about this phenomenon.

In this context, I assume the definition of a creep is someone who joins a group or an activity just to approach people romantically/sexually.

The problem is.... where should a man find a romantic partner without being a creep? By that definition, if he wants to join salsa class to find a girlfriend, he is already a creep.

The only appropriate place to find a girlfriend without being a creep is on Tinder or Bumblebee which have a slew of problems.

You heard someone giving advice that online dating is disaster and a man should find a girlfriend in social settings, like.... yoga class, salsa class.

So I try to mitigate this problem by building this dating app.

> Are feminists forcing women into focusing on their careers or just giving them the option?

So the answer to this question is very complicated.

A husband complained that his wife wanted to be a stay-at-home mom: https://slate.com/human-interest/2021/03/sudden-sahm-concern...

As you can guess, there were many reactions to this article. A woman argued that a working mom is a better option: https://twitter.com/JillFilipovic/status/1369685618863841280

Of course, there is other side of the coin. Some argued women should be given an option to be a staying-at-home mom: https://twitter.com/dvassallo/status/1369865452642471938

> is to not be career driven

I'm building ParttimeCareers (https://parttime.careers) to tackle this problem. I think part-time remote jobs can be reasonable accommodation for people who want to work and take care kids. Basically, you'll just need to work 4 or 5 hours per day or less if you spread it into weekends.

> women-only can send a flirt

So something similar to Bumblebee. Thanks for the feedback.

langitbiru··on College as a Marriage Market
Thank you. Less than 1000 registered users are on SwanLove. Basically, I'm dealing with marketplace problem (chicked and egg problem).

Yeah, a lot of people told me that dating for Linkedin is stupid. :)

But it's just beginning. I want to add dating to other online places like Strava, GitHub, Twitter, Chess.com, and so on.

The idea is you may find someone you like on Chess.com and you want to convey your interest to them but you're afraid being "punished" because Chess.com is not for dating. You can replace Chess.com with Strava, GitHub, or other social medias.

You can see how many women complaint about getting unwanted advances in Twitter. So I just want to separate people who want to date into a group with SwanLove.

langitbiru··on College as a Marriage Market
I get you. But the climate has shifted. "Unwelcome advances" can be different things to women. How do you know for woman A the "unwelcome advances" means this thing but for woman B it means other things.

Lemme ask you. Asking a phone number from a woman is acceptable or not in a gym? It depends on whom you ask. Some women think that gym is strictly for working out. Other women are more open to this kind of approach.

Not every man has high EQ, can read the room and women's body language. Not every man is social savvy.

When building this dating app, I'm thinking of a group of men which are not so good approaching women. Getting courage to approach women is already exhausting. But it's not enough. You have to know which women are open to dating.

> I don't really get the "movies / TV series preferences"

Basically, I'm experimenting with my dating app. I built the dating app with the premise on some people want to find dates in Linkedin. So I give them space in SwanLove.

Then I'm thinking of adding other social medias to it. So you can find dates in GitHub, Twitter, Strava, Chess.com, etc.

In a nutshell, SwanLove adds dating to any social medias.

Then some people tweeted about creating a dating app based on movies preferences. So I added that to my dating app as well.

I'm throwing many darts and see which ones are stuck.

> I beg you please never sell out to Match Group

So a couple of days ago, some people in HN criticized me on creating this centralized dating app. It would become a honeypot for hackers. So that gave me an idea to build a decentralized dating app (like GitLab or WordPress).

Yes, I'll do my utmost not to sell out to them.

langitbiru··on College as a Marriage Market
Yes, I already support that. You can "like" people publicly or secretly. The thing you talk about is "liking secretly". If both people like each other secretly, the interest would be revealed to them.
langitbiru··on College as a Marriage Market
Maybe they are single and want to find romantic partners. Some women like to find partners who share common interests. Imagine you like to cycle and you like to find a romantic partner who also like to cycle. Wouldn't that be great?
langitbiru··on College as a Marriage Market
> What I don't see is that people join the institution with that market as an intention.

Perhaps that happens because society would judge people to be creepy if they did that. Imagine you were a man and you announced to the world that you joined a yoga class not for yoga but for finding a girlfriend. The vibe that you broadcast would probably backfire on you.

I'm experimenting on adding dating/marriage market to the institutions like educational institutions, work, sports clubs, and so on.

I'm working on SwanLove (https://swan.love). Right now, it's just an ordinary centralized dating website. But I plan to build a decentralized dating app (without crypto). It's akin to GitLab or WordPress. Say, you own a gym. You can host my dating app yourself (https://yourgym/dating) or on my site (https://swanlove/yourgym). Then anyone who wants to join your dating app must have your gym membership.

This way, a man in your gym who is attracted to a woman can send his like in your dating app. A woman can ignore or receive the romance invitation. Without this dating app, a man has to approach a woman in your gym. That, to some extent, can make a woman uncomfortable. You read some complaints from women about unwanted advances from men in gym.

You would say that hitting on women is not appropriate in gym. So which places are okay to hit on women? My female friend told me that it's okay to hit on her in yoga classes. But what about tennis club, salsa club, workplaces?

This is why I'm experimenting with this decentralized dating app. I know, I know, to some extent, this dating app can kill spontaneity.

langitbiru··on Dating Sites Are Not Built for Men
Hey, none taken. I'm happy to receive feedback. If you look at my profile, I still got other projects in case this SwanLove is a stupid idea.

Responding to your point: you don't have to integrate Linkedin to your dating profile in SwanLove. You can integrate Strava account to your dating profile so you can find people who like to run or cycle.

In the future, in SwanLove, you'll have:

https://swan.love/linkedin (for people who want to find mates in Linkedin)

https://swan.love/strava (for people who want to find mates in Strava)

https://swan.love/github (for people who want to find mates in GitHub)

Knowing that your date has a Linkedin profile can give some security to some people. Some people only want to date people with a job.

langitbiru··on Dating Sites Are Not Built for Men
I mean, the online dating is already Black Mirror-esque for most of men (if you read the article). Whether my solution is a genius solution or a stupid idea, time will tell and it's up for debate (which is what we are doing here).

I mean, I still have backup projects if this idea is stupid or does not take off. I can still write DeFi app. I have a part-time jobs board. I have a tool to predict the salary range of jobs. So it's not the end of the world if SwanLove is a stupid idea.

langitbiru··on Dating Sites Are Not Built for Men
> Snarfing up tons of data is just a ticking time bomb waiting to happen.

What about a decentralized dating app (it does not have to involve crypto)? So think it as WordPress but for dating. Say, you are a priest and you have a community where you want them to find mates. So you can download SwanLove.tar.gz and install it on your server. Then your community can use your app. So I don't own the data. Maybe you can pay me $10 per month for the license.

> But think about this: would you want to spend the rest of your life married to someone who considered things like your salary or your Strava data or other such superficial metrics as important markers of your value as a human being?

I mean, finding mates is technically superficial. Someone said, "men are pigs, women are gold diggers. But that doesn't mean true love cannot grow between them."

See it from women's perspective, "Do you want to marry a man who is sexually attracted to you?" By the very definition, the man is already superficial. But again, it's nature who forces men and women act this way.

For example: https://www.todayonline.com/singapore/singaporean-women-pref...

"39 per cent of Singaporean women will go out with men who earn less" -> So 61% women go after richer men. By your definition, men should not marry them because they are superficial. But again, it's nature who makes them act this way. It is what it is. I don't blame them. If you want, you can blame nature.

However, I think just because a woman is attracted to a man with high-income, it doesn't mean that they cannot learn the true love. Men and women can learn to build a deep meaningful relationship. But in the beginning, we have to admit that we are attracted to superficial things.
