netvarun··on Is It Time to Rethink Globalized Supply Chains?
Also this fails HN’s guidelines of title editorializing, by including the author’s name.
netvarun··on To get good, go after the metagame
[off-topic] Kinda late to the party, but always a pleasant surprise to see an article written by a former schoolmate you've lost touched with trending on HN :)

Hi shadowsun7!

netvarun··on Telling Whiskey from Whisky

  A Scotsman who spells
  Whisky with an ‘e’,
  should be hand cuffed 
  and thrown head first in the Dee.

  In the USA and Ireland, 
  it’s spelt with an ‘e’
  but in Scotland
  it’s real ‘Whisky’. 
  So if you see Whisky 
  and it has an ‘e’,
  only take it,
  if you get it for free! 
  For the name is not the same 
  and it never will be,
  a dram is only a real dram,
  from a bottle of ‘Scotch   Whisky’.
  ~ Stanley Bruce.

netvarun··on VMware to Acquire Bitnami
Daniel and Erica are two of the most thoughtful and kindest founders I know. We got to know each other during our yc batch (w13) and it’s been a great privilege to have Daniel as an advisor for my company.

Can’t think of a better match - the company that pioneered the App Store for servers joining the company that pioneered/commercialized virtualization.

netvarun··on Ask HN: How to self-study mathematics from the undergrad through graduate level?
As an alternative I would suggest a top-down approach. Start with the theorems/results you truly wish to understand and work backwards.

There was a great quote from an interview of Peter Scholze (one of last year's Fields' Medallists), which has really changed how I view learning:

At 16, Scholze learned that a decade earlier Andrew Wiles had proved the famous 17th-century problem known as Fermat’s Last Theorem, which says that the equation xn + yn = zn has no nonzero whole-number solutions if n is greater than two. Scholze was eager to study the proof, but quickly discovered that despite the problem’s simplicity, its solution uses some of the most cutting-edge mathematics around. “I understood nothing, but it was really fascinating,” he said.

So Scholze worked backward, figuring out what he needed to learn to make sense of the proof. “To this day, that’s to a large extent how I learn,” he said. “I never really learned the basic things like linear algebra, actually — I only assimilated it through learning some other stuff.”

netvarun··on Vinod Khosla with Sam Altman on How to Build the Future [video]
I think it's a tired meme - just like the 'Stephen (Wolfram) The Braggadocio' meme. It starts getting quite annoying after a while. Especially in the latter case since Stephen blogs quite a bit and lot of his articles do trend on HN.

Repeatedly pointing out, hmm, their 'flaws', just detracts from the actual subject matter. And btw, I did enjoy this talk and likewise most of Stephen's blog posts/writings. [Only exception when such a comment would be warranted is when Stephen talks about humility ;)]

netvarun··on The Triple Jeopardy of a Chinese Math Prodigy
>> What else would you call one of the top math students at cambridge?

I would call him a good, hardworking student. (At least that's what we'd call it in Singapore ;) Coincidentally me and Xu went to high school at the same time in Singapore)

If we labelled everyone who did well in the undergraduate curriculum as prodigal - the word itself starts loses its meaning.

Let's take the top 20 universities across the world (harvards,mits, tsinghuas, iits etc.) and take the top 10 graduating students from each class (math, physics, etc.) => are we saying that the world is producing 500-1000 prodigies every year?

netvarun··on The Triple Jeopardy of a Chinese Math Prodigy
Can we stop using the term ‘math prodigy’ for someone who was essentially a quant monkey - that too at best a decent one?

He ain’t no Ramanujan, or a Terrence Tao or any of the recent Fields’ medalists who have poured their heart and soul into their craft with no expected financial return.

netvarun··on Sales results from getting 3M views on YouTube
TLDR: barely any increase in sales/revenue after a really popular YouTube channel did a video on them. Possible causes include having no direct clickable link or the channels’ viewers don’t quite monetize well (or maybe this is endemic of YouTube)
netvarun··on Ask HN: I'm good at coding but bad at competitive coding
Peter Norvig, director of research at google, made some observations on this topic: https://www.reddit.com/r/programming/comments/44kpzk/peter_n...

I was somewhat involved in the programming Olympiads in high school and to a lesser degree icpc style programming in college.

And later when I founded my own startup - I thought these competitive programmer types would be great hires. But in reality it’s been a bit of a mixed bag. Real world software engineering is about readabiliy, maintenance, extensibility, etc - the actual data structure and algorithm work is typically minimal (which these competitive programmers relish on) and even then you’d probably want to delegate to some battle tested open source library.

Of course I don’t want to hold having a competitive programming background against the candidate but no longer prioritize that skill set.

Thanks, fixed.
netvarun··on Dragonfly: Alibaba P2P file distribution system
Container image distribution seems to be one of the primary problems this tackles:

"DevOps ... brings a lot of challenges: the efficiency of image distribution, especially when you have a lot of applications and require image distribution at the same time. Dragonfly works extremely well with both Docker and Pouch, and actually we are compatible with any other container technologies without any modifications of container engine."

FWIW, this was a similar problem that I tackled for Golang gopher gala hackathon 2015 - a custom bittorrent based docker image registry POC.

https://github.com/netvarun/docket

Interestingly my problem statement was somewhat similar:

"Large scale deploys are going to choke your docker registry. Imagine pulling/deploying a 800mb base image (for example the official perl image) across 200 machines in one go. That's 800*200 = 160GB [EDIT: Correction thanks to kingbirdy] of data that's going to be deployed and it'll definitely choke your private docker registry (and will take a while pulling in from the public image)."

netvarun··on Solving dynamic programming interview problems
Being able to solve dynamic programming problems may or may not get you a job but it certainly will get you a medal at high school programming/informatics Olympiads.
netvarun··on Chess boxing
On a related note, RZA is big fan of chess. Doesn't surprise me to see the Wu-Tang clan have a chess themed song.

In a 2007 interview [2] he says that, based on Josh Waitzkin's appraisal, his (unofficial) ELO rating would be around ~1400 ELO
