In science these days, the term "Law" is almost never used anymore, the term "Theory" replaced it. E.g Theory of special relativity instead of Law of special relativity.

Yes! I think that might be a more exact title. This is what I mean:

First point: - Mountain: Cerro Lago del Congo (The GPS coords refer to the peak) - Locality: Liborina - State: Antioquia

Second point: - Mountain: Sierra Nevada de Santa Marta (The GPS coords refer to the peak, called Pico Cristóbal Colón) - Locality: Santa Marta - State: Magdalena

Pd. Hope you enjoyed your visit! I think Colombia is beautiful (But hey! I am biased)

Hi! Colombian here. I reviewed the second prediction and believe the tags are incorrect. They should be: Pico Lagos del Congo, Liborina, Antioquia to Pico Cristóbal Colón, Sierra Nevada, Magdalena.

Additionally, the GPS coordinates might need adjustment, as there are several prominent peaks near both Liborina and Pico Cristóbal Colón (the summit of the Sierra Nevada mountains).

I am porting/adapting the Digital Euro (CBDC) specifications for Colombia to complement Bre-B (our instant payment system modeled after Pix). I plan to submit it for review to BanRep (our central bank) once it's finished.

I disagree. For a long time now, the business of banking has been very much related to software. Software companies need a license to fully manage their money.

From an economic standpoint, for these companies to see a return on their investment, won't they need to replace jobs? It will be challenging to recoup investments by charging regular users in a post-DeepSeek era. While I don't support job losses, aren't they the expected outcome?

We are getting a copy of Pix here in Colombia called Bre-B, it will be launched in September 2025.

It's hard to say, considering studies attribute 50% to 98% of road wear to them.

ICE vs EV difference is negligible compared to 18 wheelers and alike on road strain.

Binance breaks every single financial law in the developing country I live. Many users have lost money in their P2P scheme. Not really a great reference.

100% this. I had almost the exact same experience and lessons learned.

I can share an example from our company’s experience:

- 5 years using Flutter - 31 full-time devs - 3 platforms (iOS, Android, and Web) - 1.3 million monthly active users

Overall, we’re very happy with our decision to use Flutter

NX works great if you are using the TS/JS stack (as we are in my company). We tried also adding our flutter repos into it and found it somewhat difficult to integrate.

The Atrato-Truandó canal in Colombia would be a much better option. No nukes required.

Is excess renewable energy being used anywhere for direct air capture of carbon? My hope is that as more countries produce surplus energy, we will massively scale up direct air capture to help address our climate emergency.

Why is the theme of "war" so prevalently overused in U.S. media? The ubiquity of phrases such as "War on X" appears to be a favored trope in titles. Is this phenomenon primarily driven by the pursuit of click engagement, or are there other underlying factors at play?

A significant portion of deaths resulted from drug overdose, and there was also a notable absence of acknowledgment regarding criminal activities perpetrated by migrants/tourists who arrived last year, despite numerous reported cases.

Many factories are relocating outside the valley, and the use of electric vehicles (including cars and motorcycles) is increasing.

Indeed, there is an abundance of butterflies, bees, and other such creatures amidst the urban area —a surprising sight for a densely populated city. However, it's not to the extent that it becomes bothersome.
