I get that, but on the other hand if someone says "if you care about privacy, you should use an e2e messenger like whatsapp", then I'll have serious doubts about whether you're actually knowledgeable or just spouting buzzwords.
They will continue to cash in from the systems of exploration they’ve already created.
I was playing with my synthesiser the other day and realized what I was really doing is using my eardrum to explore the search space of oscillation patterns, and their combinatorial sets.

Music in this sense is the class of all time series of combinations of such patterns that we find resonating as we are able to encode and decode emotions and feelings from these sounds (as well as appreaciation for them).

I wonder what other cool things we can do with this singal processing ability of ours as we enter the age of brain computer interfaces and psychedelics.

"eventual compatibility with x86-64 macOS binaries (Mach-O) and libraries"
Now I really want some plasticine / modeling clay to attach to parts of my pinnae and experiment with my ability to localize sounds.

Have video games already emulated the spectral effects of sound direction for players using headphones, or even speaker systems with known spatial distribution? I can imagine modulating the sound coming from an in-game object to match its perceived source direction to its location relative to the player.
It's super easy to construct binaries and bitstrings even when you need to work with award sizes or set bits at weird positions and IMO looks a lot cleaner than a lot of shifting and boolean operators. For example constructing a 8-bit LAPB Information transfer control field might look like:

build_info_control(SendSeq, RecvSeq, Poll) ->
<<0:1, SendSeq/bitstring, Poll/bitstring, RecvSeq/bitstring>>.

Where the `SendSeq` and `RecvSeq` are 3-bit sequence numbers... say one of them is `<<2:3>>` (0b010) and Poll is a single bit (you can see the format here: https://imgur.com/a/9bVBM0W). This field would then be stuck into a binary representing the entire frame.

This could probably be made a littler simpler, though, as I'm still rather new to Erlang.

Note you also do get bit shift operators for cases when they’re an appropriate solution (`bsl` and `bsr`)
irresponsible to who? The other people that have made the same decision and accepted the risk? or the people who are vaccinated and have pretty close to zero risk?
I think the argument is that it shouldn't take 10 readings to understand a very clear and good paper in your field. There's likely an easier way to communicate dense information.
Re: Nato, fair point. There is still a difference between being bullied into submission to American hegemony and being part of the us empire.

I really, really detest cold weather and drunk people, both of which Russia has in abundance. Russia and China are just as offensive to my own moral compass as the USA.

Once we attain citizenship I’m going to try to convince my family to move to Esbjerg, at least for a few years.
This is a fantasy. Voluntary contracts imply that workers have the option of not working for starvation wages, which in many cases is simply not true. If your options are to work a dead-end minwage job or, well, die on the street, is it really a voluntary contract that you're entering? I would say not.
Historically not been the biggest fan of Mozilla but I really, really love this project. I'm glad they're keeping it alive.
The strongest plausible interpretation is that the comments haven’t randomly thrown away the context of the conversation.

This entire conversation is about the dangers of encampments, and how to solve that problem.

Also you haven’t explained how your comment isn’t a non-seqitur. As far I can see it is an out of context contradiction that doesn’t change anything about the meaning of anything.
It’s a database of hashes, not images, though, right? I would argue the hashes absolutely should be public, just as any law should be public (and yes, I am aware of some outrageously brazen exceptions to even that).

Anyone should be able to scan their own library against the database for false positives. “But predators could do this too and then delete anything that matches!” some might say, but in a society founded on the presumption of innocence, that risk is a conscious trade-off we make.
Constant invasive changes (Pocket, Hello, Mr Robot advertisements, etc. pp.) coupled with performance issues (freezes for a single frame every second on Linux, on top of hardware acceleration issues) and lack of support by video chat softwares (can't get around that during a pandemic) forced me back to Chrome.

And honestly, I don't see why I should go back as long as the first issue isn't addressed by significant leadership changes. Mozilla has repeatedly demonstrated their willingness to trample my privacy, why should I ever trust them again?
How to create a successful Fintech Startup?
One of the most noticeable additions in my opinion is Guarani, the first Indigenous language of the Americas to be added. Indigenous languages are extremely poorly supported and forgotten by all of the major platforms and companies, and it's great to see one getting the attention they deserve. (Disclaimer: I was involved)
Yes! Also, not tied to golden visas, but in Italy we have this going on: https://1eurohouses.com/ . It is legit and not the classic Italian scam (it's sanctioned by the government).

If you're Italian and living abroad, you can vote to elect one of the few members of parliament which actually represent migrated Italians. This way they can still have a bit of representation, but without the same amount of influence as if they were living in the country.

Nino Foods (YC S21) - Cloud Kitchens in India - https://news.ycombinator.com/item?id=28073553
We are building Titipku (https://titipku.com/) which is "Instacart" for local markets in Indonesia, where we help households to buy daily groceries from nearby local markets in their residence areas. The Covid 19 has made people unable to buy their daily needs from local markets, meanwhile merchants in local markets are also suffering and need help to sell their goods. We solved this by helping to on board all merchants in every local market in our application, households can make an order in a few minutes, and there are personal shoppers who will go to the local market, buy the order and deliver to buyers. For example a household in Kelapa Gading Jakarta can make an order to buy many products from many merchants in Mandiri Market Kelapa Gading as one single order, then Titipku will assign the order to a personal shopper who will serve the order until delivery to the buyer instantly.within 1 hour. You can see an intro video here: https://www.youtube.com/watch?v=0b6SXH0BR-w. Happy to answer questions!
Hi HN, we are Bruno and Guilherme of Jestor (https://jestor.com/). We make a no-code tool for COOs that need to scale complex offline operations such as hospitals, hotels and kitchens.

At our previous company, a software development business, most of our clients asked us to build in-house tools like an "easy to use Salesforce" or a "lighter SAP" that would reflect their internal processes. They were tired of paying high prices for 20-year-old enterprise software that was slow and expensive to adapt to their operations. They would usually also say something along the lines of: "I don't want to depend on you guys, I need something that my operations team can adapt themselves". All of them were using some combination of spreadsheets and SAP/Salesforce, and were not happy. We decided to develop software to empower them to build their own tools for operations, thus killing our previous business.

We achieve this by providing essential functionality without code, and enabling more customized behaviors to be quickly implemented with basic scripting ("low-code"). We give operations teams a way of using relational databases, setting up permissioning rules, and creating dashboards, forms, tasks and automations. Low-code allows for customized behaviors and integrations such as customized UIs, which allows for applications to be run on top of our platform. Proptech companies are using Jestor to manage room cleaning operations (cleaners have a Jestor app on their phones and receive information about where they need to clean), and foodtech companies are using it for managing warehouses and logistics.

Most of our clients have field operations, like when a doctor visits a patient in their home, so everything we build is designed thinking of mobile use. For example, you can create no-code automations straight from your phone. Another thing that's really important is the ability to connect any data in your company, so you can choose to integrate data from multiple teams in Jestor.

We never liked the pay-per-seats pricing model, so in Jestor, so we only charge based on usage. We believe it's much fairer to pay according to the value we generate for the user, instead of their "team size". Also, the more people using Jestor the better it gets. We're very pumped to be here and looking forward to hear what you think! Please leave us your feedback, including criticism so we can improve!
We are Jan and Anahi of Perfekto (https://www.perfekto.mx/). We offer imperfect produce in Latin America, helping to reduce food waste as otherwise the food would be thrown away. We offer a subscription box, delivered to your doorstep.
We started with fruits and veggies as 54% of them are wasted in Latin America, mainly due to two reasons: strict industry standards around aesthetics (too ugly, too small, too big, bruised, etc.) and inefficient supply chains (supply and demand mismatch, several intermediaries, no cold chains etc.). Meanwhile 8-10% of global greenhouse gas emissions result from food waste, and food demand is growing significantly.

I was working for a Swiss FinTech in Mexico City, but was not happy. I wanted to build something with a positive, sustainable impact. The food waste problem popped into my mind because growing up in a Swiss farming village and having worked as a waiter during my studies, I saw the effort in producing food and the amount of food we waste daily. I also realized there were not many people addressing the problem in Latin America. Further research showed that more than 1/3 of food in the region is being wasted. During that process I met Anahí, who started her career at Unilever and the past few years at Uber, where she led Grocery and Cornershop initiatives. Her father is a citrus producer so she was confronted with the problem of food waste pretty much her entire life and also wanted to do something about it.

We buy fruits and veggies from producers that otherwise are difficult or impossible for them to sell - the only standard is that they have to be fresh. We thereby create a market for these 'overlooked' products. Producers are not even offering imperfect products anymore because they think there is no market for it. When we approach them wanting to buy imperfect products they are surprised and distrust us. It takes some time for them to open up. Meanwhile, at least in Latin America, many people don't seem to know that this problem even exists. They don't know that so much food is being wasted for stupid reasons like shape or size and it blows their mind.

By sourcing our products directly from producers we shorten the supply chain. We maintain a cool temperature, which leads to less waste. We only buy seasonal and local produce to be as sustainable as possible. Thanks to the subscription model, we can match supply and demand to avoid over-buying stock that ends up wasted. This allows us to optimize logistics. Logistics is definitely the most complex thing about our business--it affects us across the board. For now we think we have figured out a good model to grow, but it will be interesting to see what happens and what will change as we become bigger!
GamerPay (https://gamerpay.gg/) is a scam-free marketplace for gaming skins and assets.

46% of gamers trading skins have been scammed more than once for either their money or their skins (survey of 5,000 gamers). 50% of gamers are under 18 and this their first online trading/cash experience. We solve this problem by integrating with Steam and making use of escrow, validating all trades. We are regulated by European Financial Services, and have a compliant way of onboarding minors, with parental consent.

I am the owner of Scandinavia's largest Counter-Strike community, with 82k members. Not a day goes by where I am not contacted by young people who lost their money buying and selling skins. They often get depressed, either because they lost a lot of money, or because it was part of their identity. In one case, a young guy lost all the money he had received from his confirmation, roughly 5000 dollars. He was ashamed and afraid to tell his family and friends. In another case, one that really got to me, a 17 year old was persuaded to give his ID to "prove his legitimacy" in a trade. The scammer saved the picture with him holding his ID, then created a fake profile and scammed hundreds of others, getting the 17-year old in trouble with the police and attacked on social media.

We did extensive surveys, found that this is a surprisingly big problem (the gaming market is of course huge) and decided that something needed to be done. Current solutions were obscure, too expensive, or unavailable due to region or age.

Example of how it works with us: a young gamer from the UK meets a US gamer on Discord or Reddit. The US buyer agrees to buy the UK seller's item. They go to GamerPay where the US buyer pays for the item. We hold the money in escrow until it's validated that the UK seller has transferred the exact item. The UK seller receives the cash on to their bank account. There is no risk in who "goes first" with the money or skin. We charge a straightforward transaction fee of 5%.

One nice thing is that for the first time, safe cross-border trades are now available. We have seen sellers from Denmark (where we're from) connect with buyers from the US. We have also seen our first seller doing 100 trades in less than 6 weeks on our marketplace. We look forward to hearing your feedback!
Hi we're Nishant and Pranav of Nino Foods, which creates and operates cloud kitchen brands in India focused on the premium market. Food Delivery in India has an average order value (AOV) of 4$ vs the U.S which is >30$. This makes it hard to run a profitable food delivery business In India. Our brands target the customers in India that order food above 7$ - which accounts for 50% of industry revenues and a majority of industry profits. This segment has 2.5 times more profitability, and stickier customers with higher expectations.

We launched 11 months ago by acquiring a Pizza chain in Mumbai-Francesco's Pizzeria, which had closed 5 out of its 6 restaurant locations and was running on fumes because of covid. We acquired the 1 active location along with the brand rights and converted it to delivery only. We set up a new brand-Nino Burgers , mostly to prove to ourselves that we could build a successful food brand from scratch.

We use hyperlocal data like - unfulfilled search engine queries on delivery platforms, highest selling menu items in nearby restaurants and highest selling toppings - to drive menu and pricing decisions. In the last 11 months we've understood how to grow sales on delivery platforms and we have designed kitchen layout, operations and SOP's to improve metrics that drive visibility on them.

Contrary to the negative sentiment shared by lots of restaurants in India toward platforms because of their 25% take rate - we have a Pro-Swiggy/Zomato attitude . These platforms make 3 times more money on orders through us than via brands with lower average order values. This aligns our incentives with them and gives us access to better data to grow and lower commission rates. Nonetheless, We still do 20% of our business via our direct channel which helps us understand customer preferences deeper and track loyalty.

We want to build category leading brands in food. A person orders food delivery 5 times a month in India. Our aim is for 4 out of those 5 orders to be coming from one of our brands.

https://linktr.ee/ninofoods has our instagram pages and an ordering website. We'd love to hear any thoughts, feedback and curiosities!
We are Anta and Karthik of Inai (https://www.inai.io/), a platform for setting up and operating your payment stack. We let you offer local payment methods, support multiple business models (e-commerce, subscriptions , platforms) and localise the checkout experience by region of operation.

Setting up and maintaining a payment stack, especially if you operate in multiple regions, takes months of developer time. Most merchants set up their stacks ad hoc, leading to loss of revenue (e.g. if you don't display Apple Pay in a certain way at checkout, Apple will penalize; same for Paypal) and wasted admin time (multiple dashboards for refunds, coupons etc). Working with a single payment provider locks the merchant in, as customer data is vaulted with the Payment Service Provider (PSP) making switching difficult. Meanwhile customer payment methods are exploding with newer rails like BNPLs (Buy Now Pay Later), open banking, QR code based and even crypto emerging rapidly

Karthik and I previously ran a DTC fitness business. Tailoring the payment stack to each market that we expanded into was a big pain. We spent weeks on every payment integration and our payment stack was a mess. We were after all running a fitness business and not a payments one.

At Inai, we provide a single unified API that connects to multiple payment providers (Stripe, Braintree), alternate payment methods (wallets, BNPLs etc). We make it easy to launch into new markets and to keep your service agnostic of PSP. For B2B companies, we make it easy to allow your customers to send invoice links and accept payments across cards and ACH.

We plan to give merchants a IFTTT dashboard to set up custom business logic (e.g. show Klarna, SOFORT, and cards in Germany but cards, Paypal, and Apple Pay in US). Merchants can view all transactions across providers, and very shortly will be able to manage chargebacks, refunds, and coupons, and get analytics on transactions (e.g. success rates by card/PSP, insights on why transactions were declined).

Payment orchestration as a concept is not new, but medium sized merchants were not being served well with the existing solutions. We found that many merchants in this category had a knowledge gap with respect to payments and therefore needed someone to hand-hold and deliver outcomes for them, so fixing this is what we are focussed on.

We are building this product for merchants so if you have a use case that is currently not being served by our product, we would love to hear from you. Your problems and pain points will drive our roadmap.
