vitorbaptistaa··on Ask HN: Activity and reading to move through mid-life crisis?
Your comment reminded me of the Optimistic Nihilism video by Kurzegesagt [1]. I highly recommend it, as they explain these concepts very well in a short 6min video.

vitorbaptistaa··on Ask HN: What are the best tools for web scraping in 2022?
It looks amazing! Great intro video.

It probably doesn't make sense for Browserflow as a business, but I'd love to find a tool like this that exported a Scrapy spider, similar to the now unmaintained Portia.

vitorbaptistaa··on Ask HN: What are the best programming tricks you know?
+100

I first heard of this in the great Functional Core, Imperative Shell [1] screencast of Destroy All Software. It allows you to easily unit test your functional core (as they're just pure functions).

vitorbaptistaa··on The world is awful, the world is much better, the world can be much better
If you enjoyed this post, I highly recommend reading Factfulness by Hans Rosling. He spent his later years trying to educate the public on the realities of the world. This book contains a series of tips on how to understand facts.

His TED talks are masterpieces as well.

Of course. The local tribes are fighting the invaders since 1500.

Ilegal logging is the first step. Take down the valuable trees, burn the remaining, and finally start raising cattle.
vitorbaptistaa··on Andrew Ng updates his Machine Learning course
Definitely. It starts from first principles, linear algebra, and goes from there. It's an amazing course.
vitorbaptistaa··on Show HN: Termius (YC W19) – Share your terminal session like Google Docs
Congratulations on the launch! Quickly sharing a terminal session is very useful, not only for getting help but also in a classroom setting.

I built a similar thing a few years ago named ShellShare [1]. It's much simpler than what you're building. Free software and read-only (think broadcast).

I wish you all the best in your startup.

vitorbaptistaa··on Show HN: Get the guitar chords from your Spotify playlists
As an alternative, I use cifraclub.com.br for many years, and enjoy the interface and the overall quality of the chords (not affiliated with them).

It's not in English, but you should be able to figure out where's the search bar and use it without much effort.

vitorbaptistaa··on Ask HN: What's the most life-changing blog post you've ever read?
Religion for the Nonreligious by waitbutwhy https://waitbutwhy.com/2014/10/religion-for-the-nonreligious...

I was raised in a Christian family, as most Brazilians are, but was never really into it. I don't remember praying after I grew up a bit (10+ years), and even before I was more saying the words than really meaning it.

Then my father passed away when I was 12 (he was in his 40s, died of cancer).

This led me on a few rabbit roles reading and talking about religion and the great questions of life. As I think many with a more analytical mindset, nothing really felt right, so I ended up being mostly atheist, with a few sparkles of buddhism and cristianity here and there.

Later in my 20s, I dated and later married an amazing woman who is a True Believer. She's the daughter of a shaman with a buddhist monk, and has been meditating since she was born.

Many more conversations ensued. I explored some of the "alternative" religions, and enjoyed especially the animist ones (Earth, Sun and Moon are pretty close to gods in my mind). I also tried mushrooms, which were amazing on breaking my usual brain paths and allowing me to see from a different perspective.

But it still didn't feel right. Again, I was trying to understand religions with an analytical mind, which can only get me so far. I felt I was missing on something big (I still do).

The world is too complex to be explained only with rationality and the scientific method, but at the same time explaining things based on dreams and our collective memory didn't seem much better.

It was around this time I read the "Religion for the Nonreligious" article.

There were no giant breakthroughs, and the text is somewhat reductionist. Still, it was one of the first times I read about religion in a way that really clicked (other times were reading about some parts of buddhism and meditation).

One of the things that religion provides to people is structure. The world is too complex, and the nonsensical things happening every day can weigh someone down. Religious people can go on with their days knowing that there's a bigger plan. I think this makes them more resilient to the life challenges that will appear, sooner or later (although this resiliency can disappear quickly, just see at the number of people that blame God after some disaster happen on their lives).

This text gave me some structure to think about where I am, where humanity is, and where I want to be. It made the world a little less chaotic, allowing me to see not only the little daily things, but also keep the bigger picture in mind.

It gave me some peace of mind and, after all these years since I first read it, I still think about it every week.

vitorbaptistaa··on NFT sales plummet nearly 90% from their peak as collectibles market cools
The difference is not in the original but in the copies. A copy of a painting can be a work of art, but it is different. It did not sit at the artists' atelier, it hasn't traveled through different places to finally hang at the buyer's living room.

That is not the case for digital works. If we get strict about it, everything apart from the original file sitting in the artists' computer disks are copies. The file you downloaded after purchasing your "original" is a copy.

But well, whatever makes people happy.

vitorbaptistaa··on A theory of how developers seek information
Not only developers, but I think most people using computers.

It feels like people have a tunnel vision focusing only on the parts of the screen they're accostumed to. The other parts are ignored.

They try something, fail, try the same thing again, fail again, and repeat until they either give up or decide to slow down and explore the corners of the screen (which often leads to them finding the error).

I wonder if this is somehow related to the "magical halo" of technology. First because they try the same thing expecting different results, second because they don't explore the unknown parts of the system (maybe for fear they'll make things worse?).

vitorbaptistaa··on Ask HN: What under-the-radar technology are you excited about?
For a real world example of this, check Madrid's city centre. This is exactly what happened in the last few years, and the result is amazing.
vitorbaptistaa··on Ask HN: What are some “10x” software product innovations you have experienced?
dbt [1] is a tool that is deceptively simple, but kind of created a new job role: analytics engineer. It allow you to define tables using SQL plus Jinja2, so you can add loops and variables to create your SQL code. It might sound complicated, but it's a pleasure to work with.

This improvement was only possible because of other improvements in cloud databases and reductions in storage costs, which allowed us to go from ETL, where we transform the data outside of the database, to ELT, where we load the raw data in the DB and transform it using SQL.

All these improvements taken together allows a single person to do a job that required a small team not many years ago.

vitorbaptistaa··on Ask HN: Those who quit their jobs to travel the world, how did it go?
My wife and I rented an RV in Portugal a while ago for only a week -- it was one of the best travel experiences I had!

I'm curious about how you found and prepared the RV, and how was living in it for a few months.

vitorbaptistaa··on Ask HN: Those who quit their jobs to travel the world, how did it go?
Although you have to be careful in some places, the world is scarier on TV that in real life.
vitorbaptistaa··on The race to teach sign language to computers
Portuguese-only, but in Brazil we have VLibras [1], which is a free open-source software to automatically translate between written text and a 3D model using sign language.

vitorbaptistaa··on Ask HN: How do I learn drawing?
I enjoyed the book "You Can Draw in 30 Days" [1]. It gets into practice straight away, explaining the concepts as you need them. The daily exercises range from 20~40 minutes.

vitorbaptistaa··on Ask HN: How do you filter the content you consume?
I've been trying, to some degree of success, to use RSS to generate my own personal "newspaper". The platform I'm using, Feedly, has a bot that learns what I like or not and filters for me. I don't have enough experience with it to comment though, but I like the idea.
vitorbaptistaa··on Ask HN: Share Your Epiphanies
Reincarnation is true, although not necessarily how it's usually portraited.

Reincarnation means becoming flesh again. I am the flesh of my mother and father and all the living beings I've eaten. And my grandmother and grandfather, and all the species before homo sapiens, up until the first living being.

I don't have memory like "that day when I was chased by hyenas in Africa", but I have a type of memory encoded in my DNA. My fear of snakes, my disgust for bitter foods, the color of my skin, and much more. These come from my past lives.

If I have kids, I'll also reincarnate myself. But even if I don't, my body will feed other living beings, and the molecules that now constitute "me" will constitute someone else. Given billion of years, someday parts of me and you will roam the earth as some future being.

I always had a hard time accepting some religious ideas because they required so much magic thinking that my reaction was to discard them. My epiphany was realizing that many have a core of truth. It's all a matter of perspective.

vitorbaptistaa··on Cypress: Fast, easy, and reliable testing for anything that runs in a browser
If you can find it, I'd be curious to read about the article you mentioned.
vitorbaptistaa··on Sony cameras can now be used as webcams for Mac
Which capture card are you using? I couldn't find mentions to it in this thread.
vitorbaptistaa··on U.S. House's antitrust report hints at break-up of big tech firms: lawmaker
"He agreed with some of the report’s recommendations, such as (...) allowing consumers to take control of their data through data portability and interoperability between platforms."

This is the key. If I'm able to talk with my WhatsApp friends from Signal, or migrate my whole Facebook account to another platform, it would make it much harder for the companies to create and keep their monopolies.

If I were a lawmaker, I'd focus my time on how to do this properly.

vitorbaptistaa··on How Normal Am I?
Even though they say the range is 0-10, I got 10.1 the first time, and 8.7 the second.

People say I look like Jesus (the "Europeanized" version).

vitorbaptistaa··on Phosphine gas in the cloud decks of Venus
If you haven't yet, I highly recommend watching to the Royal Astronomical Society Press Briefing [1], where the main researchers present the results of their research. It's just 30 minutes and pretty well explained (although I'm not an astrophysicist).

One of the researchers, Dr. Clara Sousa-Silva, also have a 2-min video on how they know about the elements in other planets' atmosphere [2], and a great explanation about what is phosphine [3]. Her personal website is one of the best I've ever seen.

2020 doesn't cease to surprise me.

The trained model doesn't seem to be available? Does anyone know if this or a similar model is available somewhere?
vitorbaptistaa··on Ask HN: Which tools have made you a much better programmer?
If you can call them a tool, tests would be close to the top of my list. One of the most important metrics for productivity is how quickly you can get feedback if something you did worked. A fast test suite is great for that.

vitorbaptistaa··on I3wm and Ubuntu 20.04 server without any useless packages
I just reinstalled my machine from Ubuntu 16.04 to 20.04. I'm using i3wm for a few years, and things never worked out of the box. The sound applet, VPN, and other small things that quickly add up.

I'm now using Regolith [1] and loving it. It offers a clean and neat i3wm installation, but still uses Ubuntu's system admin tools. It was really simple to install: just install Ubuntu, add its PPA and run apt-get.

I highly recommend it for anyone that likes i3wm but doesn't want to be fiddling with configuration files to connect to a new WiFI or pair bluetooth headphones.

vitorbaptistaa··on Psilocybin Produced in Yeast
Clichés have this issue. They are the fruit of deep introspection by generations, but the end result feels so small that it can be easily ignored.

We are all connected. Love thy neighbor. Consciousness is an illusion. Yadda yadda. Boooring.

We hear them so much that we become numb and don't give them a second thought. Yeah, we are all connected. So what? I have more important things to do. And we do, of course. The rent is due, COVID-19, wars, and so on.

Then, at some point in people's lives, we stop and ask: why? What's the point in all of this? We get so lost in the day to day that it's hard to see the forest from the trees.

Psychedelics give you a different perspective. It's like going for a ride in your inner self. You might come out now just knowing these clichés, but feeling them. This difference is immense [1].

The same can be done via spirituality and meditation, but there are very few (if any) ways to experience these things as intensely and as quickly as with psychedelics. The challenge is applying these insights in your life, otherwise it's just a fun trip.
