lrmunoz··on A Secret Trove of Rare Guitars Heads to the Met
What is a "a 200 Euro guitar and a 250 Euro amplifier" setup that you recommend? Honest question.
lrmunoz··on Kaboom – JavaScript game programming library and environment
It seems this is aimed at young people learning how to program. My main problem with using Javascript as the first programming language to learn is the asynchronous callback paradigm, I believe it's too complicated a concept to teach in the very beginning (and you can't get around that with Javascript).

When I evaluated different languages / environments to start teaching programming to my daughters I decided not to use Javascript because of that, chose Python instead (and now I'm also considering making games with Roblox, which is based on Lua. The dev environment is quite complex but with supervision Lua is a nice & simple programming language)

lrmunoz··on Show HN: Amplication – Instantly Generate Node.js Apps with GraphQL and REST API
How does this compare to https://redwoodjs.com/ ?
lrmunoz··on Obsolete trig functions and why we don't use them anymore (2013)
My math teacher was in love with the Euler's identity written like this: 1+e^(i*pi) = 0

He said it relates the most important numbers and constants of the universe. He had it embroidered and framed on his office wall

lrmunoz··on Dance is superior to repetitive physical exercise for brain plasticity (2018)
I don't know why this comment got downvoted. I personally thing there is so much truth in it.

I practice Olympic lifting (total beginner) and I have to concentrate so much during exercises. Take for instance the snatch movement [1] which is my personal favorite and one of the hardest (in my opinion)

Also I find weightlifting very addictive: when you do the movement successfully is very rewarding. When you get it wrong you can't wait to try again next time

lrmunoz··on Things I wish I’d known about CSS
Best resource I've found to learn the foundation of HTML/CSS is Shay Howe's guides [1]. I think it doesn't cover Flexbox and more advanced layouts, but it's totally worth a read. I still go back to it as reference from time to time.

lrmunoz··on SARS-CoV-2 seroprevalence in healthy blood donors during Covid-19 Milan outbreak
It is not #3, if we believe what they say in the study:

"The test had a 98.3% specificity and 100% sensitivity"

I.e. only 1.7% likelihood of false positives

EDIT: And no case was missed

lrmunoz··on Ask HN: Quitting Big Tech, what is it like?
Nice story! I'd love to try do exactly the same, did you have to move to Cambridge for your CS PhD?

For context, I have a graduate diploma from the Judge business school, but that was a semiresidential program that allowed me to live in my country.

lrmunoz··on Spanish government orders GitHub to take down Tsunami Democràtic repository
The title is misleading. Alternative correct title: "Spanish judge orders to take down Github repository"
lrmunoz··on The Long-Term Stock Exchange Comes to Life
Hi Eric, are you using the Lean Startup methodology to develop this? It seems to me you're trying to solve a very big problem directly, and there is less room for iteration... Would you say that when the LTSE opens in 2018 it is an MVP and iteration will start?
lrmunoz··on Effectual Reasoning: What Makes Entrepreneurs Entrepreneurial? (2008) [pdf]
The effectuation theory is like an epiphany. To me it explains very well the sometimes counterintuitive elements of entrepreneurship. I wonder why this doesn't come up more in HN (in fact it's the first time I see it in the front page). I guess it's too academic compared to for instance the Lean Startup principles.

Shameless plug: If you want a non-academic summary of the theory, a few months ago I wrote about it in my (former) company's blog: https://www.codelitt.com/blog/5-principles-of-successful-ent...

lrmunoz··on Before You Grow
Sorry for the shameless plug, but just by coincidence, I have recently started building a simple NPS tool. Currently it's only a landing page, but I'd appreciate anyone interested to subscribe: https://nps.io

I have extensive experience applying the NPS to the hospitality industry, and I can tell you that it's not a marketing gimmick as I have read in some other comments. That's why I decided to roll my own service :-)

lrmunoz··on EU Announces That All Scientific Articles Should Be Freely Accessible by 2020
After the final recommendation the European Commission has proposed about the abolition of roaming charges [1] I'm very skeptical about this type of announcement. Still publishers won't probably be able to lobby as hard as telcos though

lrmunoz··on Ask HN: Founders whose startups have failed, where did life take you afterwards?
I realised my startup had failed last year, and part of the realisation was that it was doomed from the start. When I was coming to terms with that I applied to a bootstrapped startup for which I'm now the CTO. It's nice to have a steady salary now while I learn a hell lot about how to run a successful business in the real world

Why did I fail? Well, basically what I wanted to achieve was only a nice idea, one that everyone loved when I explained it. But then, when we implemented it, it was so badly executed that it didn't do anything useful. Then we fell in the feature creep trap, I argued with my co-founder and he parted (because I didn't listen to him, and because he wasn't 100% committed), pivoted into another failing product (at least I managed to sell it and have some real customers) and finally entered into zombie mode for a while (actually the company is still officially in business as I had to take on some consultancy projects in order to pay back €50K in loans we took). Total time of my life spent: 4 years.

In the future, I will try it again, and of course I will do different. First of all, it'll be small from the start (I'm even thinking of doing something that just provides some passive side income, in the level of 1000€ a month). Then it will have to be profitable from the beginning.
