ribrars··on Concern in Europe that the Ariane 6 and Vega-C rockets will not be competitive
Agreed! 600k per organization seems like pennies compared to the Billions invested in SpaceX so far.
ribrars··on Bill Gates Says that Bitcoin is bad For the Planet
This has everything to do with our societies being powered by fossil fuels and nothing to do with bitcoin. High energy usage may be deemed wasteful, but if it was coming from solar power, it wouldn't be bad for the planet.
ribrars··on Talking out loud to yourself is a technology for thinking
Life pro tip, if you don't want to be seen as a "crazy" person, slap on a pair of headphones and activate your phones voice recorder. You can pretend to be on a phone call, record your thoughts, and no-one will be any of the wiser.
ribrars··on Brave Complies With Apple iOS Guidelines
Well maybe... it's certainly a different approach than being tracked, surveilled and served up personal ads.

Brave is using cryptocurrency as an alternative revenue model for content creators than advertisements, and in some ways it's much more of a "white mirror" kind of tech.

ribrars··on AlphaFold: a solution to a 50-year-old grand challenge in biology
I think the key here to replicating the success is the deployment of deep learning effectively. But I would argue that deepmind's resource pool is immense, it's backed by Google. The resources of GPU's (and more advanced TPU's) are in abundance... not to mention the many brilliant PhD scientists who work there.
ribrars··on Some Blizzard employees are dreading BlizzCon
The optics are different.

Blizzard took away the winnings from one of their own loyal / hard working gamers, whom other gamers are sympathetic to as it could have been "them". This was a public forum with a specific person who seemingly did nothing wrong being punished unfairly, leading to the controversy were seeing.

Apple just removed some apps that people in the west weren't really using that much. More anonymous and somewhat blameless, a-lot of people aren't app developers and can't relate to that experience.

ribrars··on Using Deep Learning to Predict the Olfactory Properties of Molecules
Great question, one could use existing known chemicals as a starting point. There could be a potential to use fMRI readings on a model organism in realtime to generate data.
ribrars··on Most U.S. Dairy Cows Are Descended From Just Two Bulls
This is real scary. One genetic flaw exploited by say a virus could wipe out the entire dairy industry.
ribrars··on Show HN: I made a resume generator for developers
This is a good example of where UX means a different thing to the user than to the developer. Just because it's available on another page doesn't mean the customer is going to take the time to go figure that out. Take these criticisms graciously and learn how your user's use your software it's going to improve your products immensely.
ribrars··on Show HN: I made a resume generator for developers
I like this. Small bug: dates for "experience" are showing up incorrect when rendering to pdf.
ribrars··on A New Algorithm for Controlled Randomness
Nice, seems like a great solution especially in the use case where this service is needed by a game server and good performance is a requirement.
ribrars··on A New Algorithm for Controlled Randomness
> How do you arrive at that 5% base chance? I actually don’t know an analytic way of arriving there, but you can get there experimentally pretty easily by just writing a loop that runs through this a million times and then tells you how often it succeeded or failed. Then you build a lookup table that contains the percentages.

I'm no stats expert by any means, but couldn't you calculate the percentages of each event occuring (and the amount to increment) using bayesian modeling?

Simply taking the product of a string of actions and calculating those seems like an acceptable solution, however I'm not sure.

The author seems to use a calculation approach, which if I understand correctly is a valid method and is sampling the distribution. But then again, not sure.

ribrars··on China is no longer importing waste – 111M tons will have to go elsewhere
More like there was a huge trash problem and they don't want it anymore... how is them handing the world a problem when the root cause of the problem is unsustainable packaging and recyclables?
ribrars··on Interactive computational neuroscience – part 1, spiking neurons
Well done, this is both comprehensive and interactive.
ribrars··on Decentralised and open scientific publishing on blockchain
The page got swarmed with trolls, but the idea is interesting.
ribrars··on Ask HN: Tips to beat procrastination and lethargy?
You're burned out. You need to sleep 8 hours a night consistently (use melatonin, l-theanine etc. if you need it)

Procrastination is a symptom of your burnout...

See if you can take on less work, but work that has higher pay. Rearrange your life so you don't have to kill yourself just to get by. Good luck!

ribrars··on Forever Labs preserves young stem cells
As we grow older we accumulate more and more mutations. Storing stem cells at a young age can not only be potentially used to generate organs and blood if / when those technologies mature... but it can also give an archive of your healthy cell type, allowing one to "restore to youthful configurations".
ribrars··on How I Took an API Side Project to 250M Daily Requests
Yeah, that would be totally hands off. But I believe you'd have to ensure that your requests didn't timeout, (3 seconds in lambda) and in this example of 10ms response times I couldn't see any issue here. If you're into python, checkout Chalice, it's being built as a "flask" like interface on top of AWS Lambda. https://github.com/awslabs/chalice
ribrars··on How I Took an API Side Project to 250M Daily Requests
Great overview here on how you solved a problem and built a business around that.

I read that you use Elastic Beanstalk for your server config, but I wanted to ask: 1. What programming language did you use?

2. What, if any, configuration did you have to do to the Elastic Beanstalk config to deal with network spikes and autoscaling?

Thanks!

ribrars··on Instagram insists littergram app is renamed
"Instagram was not an already established word as far as I'm aware and was developed purely as a brand name for a photo-sharing app"

INSTAnt teleGRAM

Looks like a mashup of two words...
