randtrain34on How random can you be? (2019)

Using a variation of this:

```

for(let j=0; j<5; j++){

  window.captureBtnLeftFunc({preventDefault: () => {}})
  
  for(let i=0; i<200; i++){
    
    if (window.prediction == window.lastKey) {
      
      window.captureBtnRightFunc({preventDefault: () => {}})
      
    } else {
      
      window.captureBtnLeftFunc({preventDefault: () => {}})
      
    }
    
  }

}

```

actually got me a pretty linear upward win line for thousands of simulated clicks

Is CLT/NLT/glulam less weather resistant (eg. against excessive humidity/moisture) than traditional buildings though?

randtrain34on Building future cities out of timber could save 100B tons of CO2 emissions

It actually doesn't, mass timber is extremely hard to ignite, see https://www.vox.com/energy-and-environment/2020/1/15/2105805... (advantages section)

randtrain34on Ask HN: How did you become one of the first 50 at a major tech company?

I got a referral from a friend that was also an early employee at the startup. I joined mostly because the people seemed smart and I thought I'd learn a lot from them and have fun building a cool product.

To be honest, most of it is just luck. My two cents is to just find really smart and hungry people, look for evidence of incredibly fast product velocity and some semblance of product market fit. For first 50, there's a decent number of post series A startups that should have those indicators.

randtrain34on “This destroys the RSA cryptosystem”

They only tested with numbers size of ~2^800, which is around 240 digits, but I believe (correct me if I'm wrong) there exists usages of RSA with over 600 digits, so it'll still take a massively long amount of time to factor those numbers...
