  1. Pix resolved this by allowing email, phone number, tax ID or random generated key as an identifier.
  2. SEPA is a banking infrastructure layer and it is not consumer focused. Also, only ~60% of European banks adopted it. While Pix was mandatory for all banks to adopt and 80% of Brazilian population already used it.
  3. It is not the same. Mercado Pago is a product from Mercado Livre and charges at least 0.8% per transaction.
  4. > Right now, the only thing that makes credit cards a better proposition is being able to pay without having enough money in the bank

    It will not take long. Banks are already offering products with credit on top of the Pix. Furthermore, contactless Pix is now available in Android phones. If we look from the financial and usability aspects, Pix will continue eating the credit card market share.

    I didn't know Thailand and Malaysia had similar systems, though. I hope the example spreads! Creating a competitive infrastructure and product is an interesting way to deal with monopolies.

  5. Brazil central bank introduced Pix a few years ago. It took over the country as the public basic infrastructure for money transfer. Totally free and instantaneous transactions between people and companies, available to all banks.

    Then, just last week, the US presidency launched an investigation considering Pix an unfair trade practice against the US.

    Actions like that may show the current direction of the US government is aligned on preserving status quo. But still, I wonder how impactful a public digital infrastructure for the dollar would be.

  6. Exactly, X userbase is going down. So less than zero sum.
  7. Nice horizontal scroll.
  8. > How is that relevant?

    Due to its size and historical reasons, we have regional power that many times could try to benefit from physical voting receipts. It was common for local leadership to offer favors in exchange for votes.

    > Nobody needs results ASAP

    You don't know Brazil. The system's speed reduces the change of undemocratic action by those in power. Since 1889 Brazil has faced ten coup trials by the army (eleven if we consider what happened on 8th Jan of this year), and six were successful. Our current system's new republic is the most prolonged period of political stability (and the most successful from the socioeconomic perspective) in the country's history, largely due to our election system. Australia, New Zealand, and other countries have different histories and, therefore, different needs.

    > Even in the absence of any specific evidence, claims of fraud are more likely to be true in a system which makes fraud easier

    Everything is auditable. Both civil and state institutions audit the system. It could be better. Making all open-source would be a massive step in transparency. But there are multiple mechanisms:

    - random sampling checking comparing digital and printed results (each machine prints a summary of the votes)

    - voters receive a number to double-check if their vote was counted (however, they can't see who they voted for to guarantee vote secrecy).

    - parallel voting: in randomly selected locations, the vote is cast to a shadow voting machine and computed in parallel to identify discrepancies.

    - public software and hardware inspection: any institution, civil or not, can inspect the entire system. The army (yes, the one that is proud of the multiple coups) was acting to reduce the system's credibility and did an inspection and could not find anything substantial.

    We can't compare different countries without a historical and social lens. NZ electoral system in Brazil would be a disaster.

  9. Brazil is area is 32x bigger than NZ, 42x bigger population. We have election results 5h after election ends and there is no evidence whatsoever of fraud.
  10. To clarify, he was convicted after organizing an official event with ambassadors from various countries to claiming the Brazilian electoral system was fraudulent. This discourse was usual throughout his term. He repeatedly claimed to have evidence, but never presented any. We now know that there was a plot for a coup [1], which failed to materialize due to a lack of support from a section of the military. Even though the superior courts have a political nature, Bolsonaro went against the law in an attempt to overtake the political system. The same way a murder trial is a crime, a coup trial also is. Today is a big day for Brazilian democracy!

  11. Definitely, it is inspiring to see so many fantastic initiatives popping up. I am emailing you.
  12. I am developing something very similar to this. Check it out:

    https://github.com/MateusZitelli/PromptMate

    I have added a couple of exciting features:

    - Autonomous mode: it can control VS Code (create/read/write files, run commands in the terminal).

    - Nice UI to add files, functions, and selections to messages.

  13. Great to see this here. I am working on a VS Code extension that provides some nice UX to use GPT for autonomous software development. Check it out:

  14. Glad you liked it! Currently, context size is an issue. The user must clear the conversation when the context limit is reached. Knowing that I added basic memory access commands so GPT-4 may store some context between sessions. To reduce the context usage I also defined a system prompt that incentivizes selecting code ranges, not entire files. With this, GPT-4 is able to solve medium-complexity tasks, including implementing commands in this extension itself. For the future I expect GPT-4 with 32k tokens will greatly improve this extension capabilities. Also, I am looking into LangChain to reduce conversation length, define goals and employ a better memory solution.
  15. I am also a developer from São Paulo and because of this community I just got a new remote job in a German company.

    Your Show HN pots are really inspiring. They really show your enthusiasm about software development, which I think it is fundamental for mastering the craft.

  16. Some ones that come to mind:

    1. Unemployment due to AI and automation will be moderate, mostly affected by the transport sector as autonomous driving improves.

    2. The political discourses will tend to extremes because the political arena is now in social media. Image ads generated by GANs and optimized for conversion will be widely used, memetics will be more relevant than ever.

    3. The run for exploration of the pacific will intensify, big companies will invade small islands for mineral exploration. It will be the new US and China economical battleground.

    4. Financial solutions that democratize access to markets will grow. Billions more will have access to foreign stock markets. Educated high-middle classes around the world will be getting richer.

    5. Service apps like Uber will be responsible for allocating significant part of the emerging countries work force. Work laws will need to be rethought around the word.

    6. Software developers are going to be OK, the software dinner keeps happening.

  19. Started to replace coffee after lunch for a short (from 15 to 30 minutes) nap. I usually would have good energy levels just with coffee, however napping brings me more clarity of mind and focus.
  20. Such a great article, during college I made a simple simulation connecting 40000 Izhikevich neurons in a squared layout, which generated some neat behaviors [1] - your article helped me understand better what was happening there. However I still find myself curious about the visible patters that emerge, would be great to have an article covering the dynamics of multiple neurons.
