joaomacp··on Weak Men Are Superweapons (2014)
Relevant: https://www.robrhinehart.com/the-new-york-times/
joaomacp··on Tencent is acquiring a majority stake in Klei Entertainment
To be clear for people that don't know: in October 2019 a Hearthstone (Blizzard game) player protested for Hong Kong while in a tournament stream, by putting on a mask (ironic right?) and shouting "Liberate Hong Kong".

Blizzard proceeded to ban the player, take away his prizemoney and also fire the live stream casters.

Following community criticism, they gave back the prizemoney to the player and reduced his ban to 6 months. Also, they said "the specific views expressed by blitzchung were NOT a factor in the decision we made". But in the official Blizzard Weibo account, they had mentioned they applied the ban to "protect China's national dignity".

Good videos about this: https://youtu.be/uXEP02K3g5M https://youtu.be/oBpcAEMd7tc

joaomacp··on Patient Regains Sight Following Artificial Cornea Implantation
It's really amazing. I don't want to be the usual cynic HNer talking stuff down, because this seems really groundbreaking.

However, corneal transplants are already a thing, and "Within the United States, the supply of corneas is sufficient to meet the demand for surgery and research purposes."

https://en.wikipedia.org/wiki/Corneal_transplantation

Of course a synthetic cornea seems like a more scalable solution, and probably reduces costs in the long term, so this is great progress.

joaomacp··on Mikhail Devyatayev
It was dishonorable to be caught by the enemy in combat, and considered a shame.
joaomacp··on FBI warns of plans for nationwide armed protests next week
German people in WW1 and WW2 also thought they were doing the right thing by invading other European countries. I guess they were "misguided", as you say.

These people were well-understood by government, who listened to their imperialist and racist demands.

Well, the rest of Europe defended themselves through alliances and coordinated military planning, and the USA did their job to bomb the authoritarian regime back to their place.

Today's "misguided" Trump extremists are part of a very big group of Trump supporters, who might very well turn the USA into a less-globalist, more authoritarian regime. Perhaps imperialist.

In this case, the best for the world would be to quickly disable US military power, ideally with precise nuclear strikes.

Nobody in this scenario is "fundamentally evil". But that doesn't mean we can solve all conflicts by "understanding these people". This is about which side / ideology has the most power.

Power is what really matters. The USA is seen as the good guys today because they were powerful in WW2. If Germany had gotten their way, they would be the good guys, and USA the evil ones.

15K seem like low numbers. Well, depends on the weapon technologies they bring I guess. Aerial support should be required.
joaomacp··on Ask HN: Show me your half baked project
Reinforcement learning goalkeeper: https://drive.google.com/file/d/1t-W0U-WC6IikniINjeRjE8Zuskx...

The agent hasn't learned anything yet. I just finished setting up the environment, adding the ball and goal.

joaomacp··on Run, Die, Repeat: How Roguelike Games Helped Us Get Through 2020
If you are looking for a super-hardcore, very tough to beat roguelike, but with great lore and world-building, check out Dungeon Crawl Stone Soup (DCSS): https://crawl.develz.org/

You can play online but I play the 'tiles' version locally, the interface is better. To have any chances of beating the game, you must check out the wiki for guides and looking up monsters: http://crawl.chaosforge.org/Crawl_Wiki

Plus, it's open source.

joaomacp··on Israeli startup claims Covid-19 likely originated in a lab, willing to bet on it
Many people are asking for the truth to come out, for China to be cooperative on investigations, etc. I would say "be careful what you wish for".

Imagine it did come out that it was an accidental lab-leak. Public opinion around the world would be super critical of China. The US would have to step in, demand certain investigations and lab inspections from China, who would of course disagree. This could very well be World War 3 brewing. Sometimes it's better for these things to stay silent.

joaomacp··on Pfizer submits Covid vaccine to FDA for approval, to distribute in December
From reading the abstract, that study comes to the interesting finding that with a highly effective vaccine, it is better to vaccinate the YOUNG first, to reduce the spread.
joaomacp··on Pfizer submits Covid vaccine to FDA for approval, to distribute in December
Don't try to convince them forcefully, or else you will strengthen their belief in brainwashing. Explain rationally why YOU believe the vaccine works, and the evidence as to why you are convinced, and accept if they don't change their beliefs.

From experience, sometimes people are very refusing when arguing in person, but over time they think it over and might change their mind.

joaomacp··on Amazon Review Scam
Another reason to consume less stuff. It's not that often that I buy stuff that really needs to be high quality. But when I do, I make sure to look for honest reviews elsewhere, on multiple websites. Of course Google will try to feed you crappy referral websites, which just write as many low-quality articles as possible, and make money through the Amazon affiliate link to buy the item. It takes some skill to dodge this and find the real stuff.
joaomacp··on Is California Libertarian?
Maybe it's better to look at politicians in a critical, rational way instead of an emotional, love/hate type of way.
joaomacp··on The polls messed up
I really don't want to turn this into a flamewar, but ballot collections and changes to election laws are because of COVID.

And yes, social and mainstream media has inflamed everything by misrepresenting Trump's side.

But let's not remove his guilt: he has said (in a speech that SHOULD be censored by both mainstream AND social media) that he won this election, and won't accept its results. This is ACTUALLY fascism (a word that's thrown around wrongly many times): for years the people's voice has been heard, and now we have a leader (and many supporters) that don't support a democratic system anymore. That's fine, democracy isn't the only available system, but it's a hallmark of the USA.

joaomacp··on The polls messed up
I also tend to agree with Peter Thiel's point on The Portal podcast: a significant number of Americans lie on polls because they're ashamed of voting for Donald Trump.

My opinion: I think deep down these people feel they are rationally wrong for voting in a president that promised to, and now is actually attacking USA's democracy and freedom which used to be touted as America's strong point. They know they're acting on instinct, and people tend to hide their instincts in public.

joaomacp··on Pygame 2.0
I used pygame for a reinforcement learning course assignment: I built a gridworld simulator where you can input a text file with the origin, goal and obstacles, and watch as an agent learns a policy using Q-learning. It's based on a visualization used in a Berkeley RL bootcamp: https://miro.medium.com/max/992/1*FnCKMEFZC9QRnxLWT3lSCA.png

I never got to open-sourcing it though

joaomacp··on The Fall of Silicon Valley
> a transformative technology that spurs an ecosystem of technologies, all of which interconnect and benefit from each others innovation.

Biotech, especially gene editing, comes to mind as a fast developing field. However, because it's health related, extensive testing and regulations means it will never evolve at the same pace as hardware and software did.

joaomacp··on My platonic ideal for how engineering hiring should work
Right. It logically follows that random applying would be a good strategy: selecting randomly from top-paying jobs, you would reply to job offers for e.g. software engineer, brain surgeon, architect or hedge fund manager, to increase the chances of being randomly hired.
joaomacp··on Google is giving $1B to publishers to help convince governments not to take more
Isn't PR the product news publishers provide?

Edit: previous title was "Google is giving $1B to publishers. For PR, not a product."

joaomacp··on Nikola’s founder steps down from board as company faces fraud allegations
Not even GPT-3 could be this nonsensical.
joaomacp··on The majority of 18- to 29-year-olds in the US are now living with their parents
Is it really bad for mental well being? I know a lot of people nowadays (including me) have the desire to live separately from parents. But mental health has been going down, with increasing rates of reported loneliness and isolation.

Society has made us individualistic / "independent". But has it really made our mental health better?

Edit: and as others have pointed out, more people living separately is not ecologically efficient / sustainable.

joaomacp··on Nim – version 1.2.6 and 1.0.8 released
I can't answer the question, but I find it exciting that we're in this age where we can have these discussions. Maybe in the future programming languages will consolidate, and people will fondly look back at these times of experimentation as a "golden age", as when Ritchie and Thompson were creating Linux, or Xerox PARC / Apple were inventing the computer mouse UX.
joaomacp··on An Argument for Race Abolitionism (2020)
As a European, every US election season I'm always dumbfounded by how much the "black vote" is discussed. Just recently, when Kamala Harris was announced as VP, all they talk about is how she will contribute to the black vote. This makes it seem as she was only chosen because of her race, and even worse: it's an insult to black people, grouping them together as having one opinion.

I don't know why there's no backlash against this.

joaomacp··on Magnasanti: The Largest and Most Terrifying SimCity (2010)
> have men be either gay or straight, but women to be bisexual

There is some scientific truth to it: https://www.bbc.com/news/health-34744903

joaomacp··on Universal Basic Income is Capitalism 2.0
But if people stop doing those miserable jobs, salaries will have to go up, which in turn will increase the price of goods and services, therefore creating inflation.
joaomacp··on How to Run a Live Coding Stream on Twitch Using OBS
You're not alone! I found your description really relatable. I find that I can only truly understand something when I know all the details, and why things are the way they are. That means in the beginning, when learning something new, I'm overwhelmed and not really confident in my knowledge.
joaomacp··on Show HN: Primo – all-in-one IDE, CMS, component library, static site generator
> Just need a commodity web host to slap it up on.

I suggest NearlyFreeSpeech. It has an outdated UI and it's very DIY, but the pricing is very good. They have an option for static sites, with a lower price.

joaomacp··on Ask HN: What kind of ideas are not VC-backable but should exist in the future?
Please don't call your company "UseLess".
joaomacp··on Hong Kong: UK makes citizenship offer to residents
Pretty soon the law-abiding and obedient people will become aware that life outside of authoritarianism is better and safer, and they will either run away or revolt.
