sysk··on How to speed up the Rust compiler in 2020
Stupid question but could Rust skip monomorphization during development builds and use dynamic dispatch? I heard generics were often to blame for slow builds.
sysk··on The growth in passive funds has caused markets to become more correlated?
Ah, it makes a bit more sense when interpreted that way. So the capital that is described as being allocated is really the company's capital to the investor, not the investor's cash to the company.
sysk··on The growth in passive funds has caused markets to become more correlated?
Thanks for the elaborate reply but I was aware of all of this already. I wasn't questioning the utility of the stock market and understand its role as a price discovery mechanism and liquidity provider.

I was however questioning whether this sentence from the article was really accurate: "The function of the capital markets is to allocate capital".

I'd argue that trading existing shares, although it contributes to price discovery and liquidity, is not "capital allocation" (unless we're talking with respect to the buyer's capital like another commenter pointed out).

sysk··on The growth in passive funds has caused markets to become more correlated?
I understand the concept of liquidity and the reward mechanism you describe but it doesn't ultimately answer my question, which why is the process of buying an existing share called "capital allocation"? Let's say I buy a GOOG share from Larry Page. Is it the idea that I "allocated capital" to Larry Page's bank account? It seems to me like the correct thing to say would be that I provided liquidity to Larry, not that I allocated capital. Or is it the idea that I allocated some of my own capital to the stock market?

> The function of the capital markets is to allocate capital.

I never fully grasped this idea. I have no problem understanding that venture capitalists, angel investors or investors that buy shares at IPO do allocate capital. However, why is trading existing shares considered "allocating capital"?

sysk··on Tesla beats expectations with $3.4B in revenue
> Tesla's 5.3% bonds are unchanged at 89 cents on the dollar

Can anyone explain this like I'm 5?

sysk··on America's Reverence for the Bachelor's Degree
> many programs have, instead of the former, means to satisfy some portion of credit requirements without actually taking classes if you can demonstrate equivalent knowledge gained elsewhere (e.g., credit-by-examination.)

Can you name some of those programs? I keep hearing about those but can't find them.

sysk··on Georgia Tech Offers Online Master of Science in Analytics Degree for Under $10K
Can professional experience and a partially completed bachelor's degree in SE substitute for the undergraduate degree requirement?
sysk··on Fidel Castro has died
I'm with you up until "the US tried to save Cuba from itself". Castro was an awful dictator but the US embargo not only didn't save Cuba from itself, it made things worse for ordinary Cuban citizens. I wouldn't be proud of it.
sysk··on The 2016 Election
This is 900% rationalization.

> When you see him and his followers advocating misogyny, racism, xenophobia, homophobia, aggressiveness, and basically all the other -isms and -obias, it becomes much harder to "see the other side" of the debate

The exact same argument could be convincingly used to discriminate against members of the two largest organized religions. Are you also going to ask potential hires who they voted for at the last election too?

sysk··on The 2016 Election
> Aren't those, pretty much by definition, the traits of a poor manipulator? A great manipulator wouldn't seem so false.

This is a good point and it baffles me to be honest. I said "great" manipulator because it seems to be working so far. Great manipulators don't necessarily need to be great with everyone all the time. Or maybe she intentionally wants us to think she's a poor manipulator so that we trust her more? But that surely fails Occam's razor.

To answer other comments, I didn't get this impression solely by watching her on TV, it is corroborated by her history as a politician and recently leaked emails.

sysk··on The 2016 Election
As a non American who would probably vote for neither of them, Hillary definitely ranks way higher on my internal psychopath detector. The constant fake smiling, cold and calculated question answering, passive aggressiveness, etc. In short, the traits of a great manipulator. Trump is guilty of some of that too but he is somewhat redeemed by the fact that he seems dumb/naive enough to believe whatever he preaches.
sysk··on On DRY and the cost of wrongful abstractions
Am I the only one who thinks this sort of advice would be immensely more useful with some concrete examples?
sysk··on Google's plan to deter aspiring ISIS recruits
> and more importantly, free access to information.

Yeah, they should provide a search engine or something.

sysk··on Keep your identity small (2009)
I didn't mean to discuss, just to correct OP in case he was genuinely misinformed.
sysk··on Keep your identity small (2009)
Yes, that's what I meant.
sysk··on Keep your identity small (2009)
Just a nitpick but atheism is not a faith, it's the absence of faith.
sysk··on Ask HN: Best way for monitoring Node.js in production?
Hey Wiktor,

First, you really shouldn't use forever or pm2 in production. May I suggest you use something like Dokku[0] or Deis[1] (if you are planning to scale to more than one server) to deploy your apps?

Dokku is really quick to setup and will save you a lot of time and trouble in the long term. Setup takes only 5 minutes and the learning curve is pretty low (maybe 30-60 minutes to be productive).

NewRelic[2] and DataDog[3] are popular for monitoring though they're not open source. Nagios[4] is open source and also popular.

sysk··on Ask HN: Should I pivot?
Yes, I could do that but it's hard to get right. I think maybe I should release a SSH server container which has dangerous commands restricted.

sysk··on Google proposes its Dataflow batch/stream tech to the Apache Incubator
Does that mean that Google will stop maintaining the project?
sysk··on Google proposes its Dataflow batch/stream tech to the Apache Incubator
Can anyone ELI5 what it means for an open source project to become an Apache project? Why doesn't Google just push the code on Github?
sysk··on Show HN: Fieldbook: Lightweight Database with a Spreadsheet UI and a REST API
I'm working on exactly that. However, I'm a bit fearful it will be received negatively by developers.
sysk··on The Triumph of Stupidity (1933)
Just a nitpick but Hayek and Friedman were both classical liberals.
sysk··on New human-like species discovered
I had to re-read the comment a few times before realising that you wrote "caver" and not "cadaver".
sysk··on For only the second time in our history the ownership of The Economist changes
> The saddest thing about Hacker News is that we all get behind radical things like FOSS (Bill Gates called it un-American) and Snowden, and fight SOPA and NSA violations of privacy, but because too many of our salaries depend on advertising revenue, our cognitive dissonance blinders go up lightning fast.

What? I don't think I've ever read a positive comment about ads on HN. Also, I'm apparently in the only one on HN who would rather see ads than pay for stuff.

sysk··on Starting Forth
Is Forth still being used in industry other than for legacy systems? (genuine question)

Here's another good one: http://www.dailymail.co.uk/news/article-2540955/Beijing-clou...
sysk··on Many Bitcoin wallets vulnerable to double-spending of confirmed transactions
Indeed. I was also surprised to find this out given how popular Electrum is. The code is here: https://github.com/spesmilo/electrum/blob/master/lib/blockch... and https://github.com/spesmilo/electrum/blob/master/lib/blockch...

One could run a modified Electrum server that sends a long chain at low difficulty and double spend Electrum users.

sysk··on Many Bitcoin wallets vulnerable to double-spending of confirmed transactions
The issue is not with SPV itself but with Electrum's implementation (by "and friends" I really meant Electrum forks, not all SPV clients).

Electrum does validate block headers but it doesn't handle re-orgs correctly. It just assumes the longest chain has the most PoW in it which is wrong and makes it vulnerable to attacks by malicious Electrum servers.

Block headers do not contain the cumulative work that has gone into the chain (only the difficulty of the current block). A chain's total work must be calculated and stored locally by clients.
