Not opening here... HN killed?
vitorgrs··on Google Hits 50% IPv6
Yeah, I tried to switch ISP. Was thinking everything was fine, then tried to watch on ClaroTV+ here (similar to Youtube TV, Hulu Live, etc), and it was... awful. Then I figured out, the IPv6 route was going from Brazil > US > Argentina, or some other crazy crazy route. While IPv4 was just inside Brazil.

So I tried to complain to the ISP, and they just said they couldn't do anything, and if I wanted, they could disable IPv6 for me...

Of course, I canceled the ISP.

Sadly it's pretty common for several ISPs have smaller peerings with IPv6, so this is not uncommon.

My other other ISP worked super fine, but even then, they had two ASN. One for IPv4 and the other for IPv6, just to show how different they were...

vitorgrs··on Google Hits 50% IPv6
I noticed when using some Chinese services, a lot of them have "IPv4" and "IPv6" flags when opening their apps for some reason.
vitorgrs··on Google Hits 50% IPv6
Here in Brazil most ISPs provide IPv6 by now... But what happens a lot, when field technician are installing your broadband, they just... don't configure IPv6. As if IPv4 (CGNAT!) wasn't enough. With bigger ISPs this is less common.

With mobile carriers this is even worse. For some reason, some default config are IPv4 by default, while literally all of them supports IPv6.

vitorgrs··on Unauthorized alert sent to cell phones across Brazil
This is not related to Google or Apple. And this extreme alert, it's sent even to cable TV automatically. In a few countries, it's sent even on Fax lines.

US/Trump nuclear attack would make people freak here in Brazil.

vitorgrs··on DeepSeek Introduces Vision
Talking about the vision... I already had the vision tab there hahahaha I guess everything in tech these days are A/B...
vitorgrs··on DeepSeek Introduces Vision
I already had it for months? What's the news here?
vitorgrs··on Rio de Janeiro's "homegrown" LLM appears to be a merge of an existing model
Piaui state it's also doing a LLM it seems. But indeed it would make more sense if it was a national thing rather than local...
vitorgrs··on Gemini 3.5 Flash
Just ask any real question about stuff. LLM is not about code only...

Yes, Gemini can actually say how much of the image is AI generated.
vitorgrs··on WinUI 3 Performance: A Leap Forward
.NET Native was experimental in WP 8.1 and W8. On 10, it becomes mandatory and you couldn't even publish a JIT .NET app to Store.

WP 8.0 didn't even had WinRT, only Silverlight apps, and all JIT. If you wanted native in 8.0, had to go with C++.

About Desktop, C++ was rarely used. Most apps were either .NET C# (JIT) or WinJS. JIT WinRT .NET was super slow, WinJS apps were even faster, which is why many apps were all WinJS, including inbox Windows apps, like the MSN apps.

vitorgrs··on WinUI 3 Performance: A Leap Forward
Windows 8 Inbox apps a lot of them where WinJS actually. But on Windows 8 even web tech was fine (speed-wise).

And WP 8.0 < didn't offer AOT for .NET apps. AoT only came as experimental on WP 8.1 with WinRT apps if I recall right. And on W10 and W10 Mobile, it comes as default for all UWP .NET apps.

vitorgrs··on WinUI 3 Performance: A Leap Forward
WinUI made sense when windows actually had a proper design guideline, and touch was also the focus. So using WinUI was just easier as the controls were all following the guidelines, and if you wanted to offer a native experience, that was the best choice.

But it's been long gone that time where Windows had a minimum cohesive guideline.

vitorgrs··on WinUI 3 Performance: A Leap Forward
If I recall right, Windows 8 and Windows Phone 7/8 during the 2010's were all developed on low end devices.

Both had huge issues UX wise, specially desktop, but performance and stability was never a issue.

Developers should always test their system on the minimum system requirement that they allow the system to be installed...

I remember I complained about WinUI performance years ago, and they told me at the time that "performance" was not the focus...

vitorgrs··on Brazil's Pix payment system faces pressure from Visa and Mastercard
Obviously there's several other ways to send money. I'm talking about the popular ones... The others are niche-systems.

And yes, in TED only the final settlement were done by BCB.

vitorgrs··on Brazil's Pix payment system faces pressure from Visa and Mastercard
Because TED is not the only way to send money now...? It's basically legacy, although yes, still used. Very rare you'll see Person to person/business using TED. Basically business to person...

And yes, literally banks had to "talk" with each other. Which is why it was paid and slower in first place and didn't worked 24/7.

vitorgrs··on Brazil's Pix payment system faces pressure from Visa and Mastercard
In Brazil case, there's actually public banks, and they use Brazilian servers.
vitorgrs··on Brazil's Pix payment system faces pressure from Visa and Mastercard
It was not. TED had to talk with banks, only the final settlement went thought Central Bank.

With Pix, banks don't talk with each other. They are basically using Central Bank API to send and receive money.

before it was Bank Z ---> Bank Y

With Pix it's Bank X ---> SPI/BC ---> Bank B

vitorgrs··on Brazil's Pix payment system faces pressure from Visa and Mastercard
It was not Pix being down, though. This is about banks using US cloud providers. The issue here was with private banks even.

As far I remember, Banco do Brasil and Caixa - both public banks, didn't went down, because they use Brazilian owned servers...

vitorgrs··on Brazil's Pix payment system faces pressure from Visa and Mastercard
tbh even cashback these days might be worthless. It need to be a considerable amount. Because most things you buy, you have a discount when buying with Pix or money...

What still make credit cards strong in Brazil it's installments though...

vitorgrs··on Brazil's Pix payment system faces pressure from Visa and Mastercard
The government already have card transaction access though. If you are in the banking system - you are being tracked. Doesn't matter if is Pix or a card.

Doesn't mean they will automatically expose you, as it requires justice approval technically...

vitorgrs··on Brazil's Pix payment system faces pressure from Visa and Mastercard
Yep.
vitorgrs··on Brazil's Pix payment system faces pressure from Visa and Mastercard
Several backs had a good amount of TED limit. Although everything changed when Nubank launched, giving unlimited TEDs to everyone. Most banks followed at the time, so basically around 2015~ several big banks had unlimited TEDs.

The problem with TED it's just how hard it was to send money. You had to insert, if I recall right:

- Person full name - Social security number - Select the Bank Name - The type of account (savings or checking account) - Agency and account number

This basically means that TED was used as a serious payment thing, like money you receive from your company, etc.

A lot of companies still use TED.

e.g you can subscribe monthly to ChatGPT or Amazon Prime using Pix. It's called "Automatic Pix".

There's Pix contactless payment. Both Samsung and Google wallet support. Samsung added a few weeks ago. Google added 1 or 2 years ago.

You can actually pay QR Code Pix now with Samsung by just opening the camera too.

Apple refuses to implement Pix on Apple Pay, and regulatory agencies are trying to change that...

Pix integration with Google Pay it's just amazing.

Imagine the situation in the US as if every app or website magically used Google Pay.

Well, that's Brazil now if you use Android. Because as soon as you copy a Pix code, it will prompt Google Pay :) And every service in Brazil have Pix... Even international ones as Stripe supports...

vitorgrs··on Samsung to exit China home appliance sales amid shrinking market share
Here in Brazil I think TCL is almost surpassing Samsung in TV sales. In Argentina it's already the leader. They sell Mini LED TVs, etc, way cheaper than Samsung ones... It's just better quality for the price. And entry level Samsung ones are cheaper quality. Samsung TU8000 in Brazil has factory issue, and they always refused to do recall.

Although in a few sectors like washing machine, I think they are growing here.

ACs they were one of the biggest for sure, with good pricing, but now, again, there's hisense, TCL, all cheaper...

Not yet... Which is a shame.
