On: PwC Hong Kong first Big Four firm to accept bitcoin

[amarpatel]

Genuinely interested in your perspective: In January '17, 1BTC was $800 and it's currently >$10,000. How can you justify spending X BTC on a good or service as you've now paid ~10x the original asking price?

[ryan-c → amarpatel]

The same way I justify not having spent every cent I could spare buying BTC over the last eight years.

I mined hundreds of BTC in 2011 to 2012, and sold pretty much everything as I went. If I'd saved it all, I'd have "fuck you money" right now, but at the time even $100/BTC seemed like a moonshot.

I'm not going to beat myself up over not having prescient knowledge of BTC or any other thing I could have invested in.

If you save some of the wages you get in bitcoin from 800 - 10k I'm sure you'll be pretty happy, not like the fiat increased in value.

> Kickstarter backers who have not received their rewards will receive a full refund within 4-8 weeks as a chargeback to their credit cards. No further action is needed.

[Leszek → amarpatel]

No, I know that I'll be getting a refund, I just wonder why the kickstarter money wasn't enough to fulfill the kickstarter rewards.

[detaro → Leszek]

Kickstarter probably mostly covers production of the rewards, not the product development.

[gerryk → detaro]

It's business 101 that the retail price should cover all production costs, including R&D, otherwise you are in shortfall from day 0.

[detaro → gerryk]

Retail price over the full sales run. Kickstarter was just the preorder phase of it and thus likely doesn't cover the full R&D, especially not if the estimates were off in some way.

On: Executing non-alphanumeric JavaScript without parentheses

[amarpatel]

I found this article had more depth: http://patriciopalladino.com/blog/2012/08/09/non-alphanumeri...

[pythonistah → amarpatel]

The parentheses-less javascript dialect in the title of this HN article relies on ES6 and uses 6 characters:

    !+[]`$

The parent link above is ES5 and uses 8 characters:

    !+[](){}

The jsfuck.com ES6 dialect uses 6 characters:

    !+[]()

jsfuck was previously ES5 but they now rely on ES6isms to shorten their code.

[mrspeaker → amarpatel]

That's a better intro, but the "point" of this article was about doing it without using parenthesis.

On: The Unlucky Billionaire – Gotta catch em’ all

[amarpatel]

> everybody,

I read that sentence too many times

[writerlexs → amarpatel]

Thanks! Fixed :)

On: GitHub Dark – Switch off the lights

[amarpatel]

This one is waay better.

On: Working fewer hours would make us more productive

[amarpatel]

The change from 31% to 48% compliance represents a 54.84% increase, not 17%.

Cash out!

On: IntelliJ IDEA 15 Released, Adds Kotlin to the Family of Supported JVM Languages

[amarpatel]

I've been using WebStorm for a little over a year, and although it's much more helpful than atom/sublime, it does tend to drag every now and again.

Do you have any tips on optimizing performance for your dev environment? It's a shame using webstorm in power save mode.

[jasim → amarpatel]

Switching between projects dragged a bit; I recently switched everything to a monorepo (https://github.com/twitter/commons/tree/master/src/bash/git/...) and now start the IDE from the repo root. Snappy now.

Also exclude node_modules, logs.

[grumblestumble → amarpatel]

I often end up marking node_modules as "excluded", which sucks a bit for autocomplete/intellisense style code insights, but really speeds things up. Switching branches seems to be the primary thing that grinds it to a halt.

[nerdwaller → amarpatel]

If you have the RAM to spare, you can up the [JVM allocations](https://www.jetbrains.com/idea/help/increasing-memory-heap.h...). The setup instructions should be adaptable to other IntelliJ based products.

[mark_l_watson → amarpatel]

I remove plugins I don't use - that might help.

Also, as other people have mentioned, "exclude" files from being watched by the editor. I do a lot of NLP and machine learning work and I often have very large text training files in my working repos - important to tell the editor to not to watch these files.

On: 23andMe meets FDA standards, adds back wellness reports

[amarpatel]

Hahah agreed with @kej. Jokes aside, I've held off getting 23andMe because of this reason. Does anyone know?

[jegutman → amarpatel]

There have always been partners you can get the entire suite of results from.[1] I don't know how they haven't been restricted, but my guess is the FDA can't ban telling you what a SNP does, but the FDA can ban 23 and me selling it as a service connected somehow? Anyways, you can find out everything you wanted to know and a million other things you probably will have trouble of fully understanding.
