freefrag··on The 4:6 method for coffee-brewing (2017) [video]
You could try an aero press with an additional attachment, such as [1], but it probably wont be able to replicate the full range of flavours of an espresso machine.

If you havent tried the classic pour overs with freshly ground specialty coffee, I would really recommend it. I used to be an espresso guy, but now I only drink filters.

freefrag··on In-memory hash tree implementation
What's the advantage of using wider trees at every level? Asymptotically wouldn't you get the same behaviour with a binary tree?

I also recommend the notes for L28[1] - Advanced Functional Programming at Cambridge. They might be a little hard to follow, but they are extremely insightful and teach concepts that may be difficult to learn elsewhere

freefrag··on Ask HN: I feel like I'm in a filter bubble. How can I “expand my horizons”?
Can you recommend any good introductory material or websites?
freefrag··on The Raft Consensus Algorithm
Yes. They even reference it on their website:

"Raft is a consensus algorithm that is designed to be easy to understand. It's equivalent to Paxos in fault-tolerance and performance. The difference is that it's decomposed into relatively independent subproblems, and it cleanly addresses all major pieces needed for practical systems."

freefrag··on MIT Hackathon winners
What exactly does the winning submission do?
freefrag··on I missed the HackerNews meet in London - will there be any more related events?
Yes, it happens once a month
freefrag··on If a mathematician wants to cross a road
Actually some "real" results in Mathematics use the laziness of light. For example http://en.wikipedia.org/wiki/Brachistochrone_curve#Johann_Be...
freefrag··on The Paradox of the Proof
He's not wrong.

To many mathematicians reality is largely irrelevant. For example G. H. Hardy, an extremely prominent British Mathematician, believed that true Mathematics is an art form and is not useful. He dismissed applications of mathematics as dull and boring.

And I can relate to him. It's incredible how complex, beautiful structures arise from a couple of simple axioms. It doesn't matter if what you study will be relevant or not, what matters is that it's fun and stimulating to explore.

freefrag··on Code Club – inspiring a new generation of programmers
This is an awesome idea! As a university student I'm trying to get involved in code club. We need to get kids hooked on programming early; make them realise that it can be a fun, creative activity and a way to express themselves.
freefrag··on Bitcoin Plunges By Nearly $30 As Largest Market Suffers Outage
Reminds me of this life-cycle of a bubble [1]. I know this drop wasn't caused by a loss of confidence in the currency but in the exchange, still I wonder if this was the bull-trap.

freefrag··on 1GB Ram & SSD Cloud Hosting for $6
Seems to be a pretty good offer, even in comparison to digital-ocean (https://www.digitalocean.com/). Has anyone hosted anything with them before? I'd like to know whether they're dependable.
freefrag··on April Fools' Day != Excuse to SPAM
I don't agree, it's just one day in a year and as long as they don't take it overboard I find it a great laugh. Besides if you're that annoyed by the email just send it to trash, it only takes a second.
freefrag··on Porn Site Breaks Down Searches By Country
Have you seen Peru? How does that country sustain itself
freefrag··on 30 Weeks of Game Development
Great job on the game, out of curiosity why did it take 3 submissions before it finally went on the app store?
