badfrog··on Spotify CEO: musicians can no longer release music only “once every 3-4 years”
Tons of amazing music with totally new sounds comes from people 16-20 years old. For the right person, it doesn't take a decade.

> Well “the price” might be totally different if there were no off-exchange orders.

I'm not sure what that means, but there's no scenario in which you'd get a worse price. That would be illegal under the Reg NMS order protection rule.

You are guaranteed a price that is equal or better than what you'd get on the exchange. Why would you want to bypass that?

From a skim, that article doesn't seem to suggest that DE Shaw has done anything illegal. In fact, the paragraph after the one you quoted from makes it look like they work hard to stay within the bounds of the law:

> This secrecy and vigilance extended to the company’s extreme caution on legal and compliance issues. One of Shaw’s common sayings, repeated at an annual training session by a compliance officer, was that it was important to avoid risks and legal trouble because Shaw wanted to make sure that his kids could go to college.

Prop traders / HFTs definitely provide liquidity. It's not clear that quant funds do the same.

> Instead you go to an anonymous arb firm, for $1m in bonds, and you say, "okay we're going to sell you the bond that is actually ours, you will sell it back to us, here is your fee, now we can sell this bond back to the client and wash the fact that it is ours."

If this was actually how the world's biggest hedge funds work, somebody would have written a whistleblower article by now.

> I think it’s bad (it’s weird/unfair)

How is it bad or unfair? Everybody wins: you get a better price, the market maker does a trade they're happy with, and your broker gets a little bit of money.

> I think its a bit presumptuous that tech workers are perm leaving the city.

The survey in OP suggests that they are, with two important caveats:

* This is obviously not even close to a representative sample of workers

* It's predicated on "if you had a choice", and we don't know how many people will actually have that choice

badfrog··on Markets, Rent and WFH
If you physically work in California yes. I don't know what happens if you work for a company whose HQ is in California but you're physically in a different state.

> Adapt solutions to your particular use case. There's no one-size-fits-all solution for everything. Compare different approaches, analyze them. Tutorials or articles show an idea, but may not present production-ready code. Always analyze it before you decide to use it.

This advice seems weird to me. I've been a professional software developer for a decade, and probably 95% of the time it doesn't matter if you're doing things in the most ideal way. The important thing is that it works, is reasonably performant, and is reasonably maintainable. If you can get that in 20 minutes from stealing somebody else's solution, it's probably better in the long run than spending 4 hours figuring out a slightly better solution. Maybe the hard part is identifying the 5% of the time when it does matter that you do something the most ideal way?

> If people's feelings matter, why don't mine?

Of course your feelings matter. I'm sure there are plenty of situations where your feelings are the most important factor to consider. But this is not one of those situations. Your feelings of minor inconvenience from being asked to use different words are less relevant than others' feelings of oppression from decades/centuries of societal biases.

> It is not painless: it is dissonant

The dissonance should be cause for reflection and growth. Why does the gendered version sound harmonious? What does that answer say about the society that evolved our language?

> and takes another syllable.

That's just silly. If typing three additional characters causes you pain, you shouldn't be writing comments on the internet in the first place.

> there isn't any ill intent to be talked about

In addition to intent, outcome must also be considered.

If the market is going down, then even cash is a better alternative.

badfrog··on Ask HN: What programming skills are required by HFT or Trading firms
If your 401k has ETFs or mutual funds in it, the fund managers are rebalancing every month or every quarter. Saving small amounts of money on these transactions really adds up when you think about compounding over decades.

> I wonder How can someone become an expert at python.

I think it's the same as becoming an expert at anything. Lots of practice, and lots of feedback from people who are already experts. The latter is unfortunately pretty hard to find unless you already have a job writing Python.

badfrog··on Chicago will now require food delivery apps to disclose itemized cost breakdown
It's not obvious that this well help anything, but at least it's better than Jersey City. They put a cap on how much apps can charge restaurants, so obviously the apps just added more fees for the customer.

badfrog··on Twitter Will Allow Employees to Work at Home Forever
> switched to another team internally because they are pro-remote and I plan on moving back to Australia

I don't know about Microsoft in particular, but from what I've seen it's much easier to find a remote position while you're already at a company working onsite than it is before you get hired.

> You want to move to the Midwest and work remotely, or apply for a transfer to a different regional office? Happy to let you do it, but know that the market rate for your skills there is X, which means an adjustment in salary for a voluntary move.

It seems like nobody wins in this situation. If my goal is to maximize savings, I'd move to the Bay Area to get the maximum salary from you and find the cheapest housing in the area. I'd be miserable because I'm living in a place I don't like in a shitty apartment. On the other hand, if you offered to pay the same amount while I live in the midwest, I'd be happier with my living situation and be pocketing more cash. This would make me more productive and make me stay at the company longer, with no additional cost to you.

badfrog··on Rebuilding our tech stack for the new facebook.com
Sure, it's totally reasonable for somebody to dislike these features. I just object to the claims that it doesn't do anything substantially different than what it did 10 years ago.
badfrog··on Rebuilding our tech stack for the new facebook.com
I think this is very unlikely. Making the page load one second faster pays Facebook more in terms of user retention and engagement than it costs them in server usage.

> Facebook rendered just fine a decade ago. What changed between now and then

It does way more things. In particular, there are a lot more interactive experiences. A decade ago, it just loaded a web page and nothing changed until you refreshed. Now live videos and other content types have streams of comments and reactions pushed to the client in real time.

badfrog··on For $39, Frontier Air Will Let Passengers Keep Their Distance
> air is recirculated

That shouldn't actually matter. As far as we know, coronavirus is not airborne. From the WHO:

> According to the currently available evidence, transmission through smaller droplet nuclei (airborne transmission) that propagate through air at distances longer than 1 meter is limited to aerosol generating procedures during clinical care of COVID-19 patients.

> as the droplets are too heavy to be airborne, they land on objects and surfaces surrounding the person.

badfrog··on How coffee became a modern necessity
> You need somebody to ban it to make your own choices?

It shouldn't be surprising that some people think that. Most people still feel that way about most narcotics.

badfrog··on How coffee became a modern necessity
> Calling coffee a mind-altering substance is pretty rich.

What? Why? It literally is one.

From wikipedia:

> Caffeine is a central nervous system (CNS) stimulant of the methylxanthine class.[10] It is the world's most widely consumed psychoactive drug.

badfrog··on New Air Force One instruction manuals cost $84M
> even the greediest tech company (oracle!) Has not thought of to charge for documentation

Oracle sells products/services that thousands or millions of organizations purchase. That's a completely different kind of business arrangement than something that a single entity purchases once. If you hire a software consultant to build you a custom system, they're definitely going to charge you for the time they spend writing documentation.

badfrog··on In 4 US state prisons, 3,300 inmates test positive, 96% without symptoms
42.4% of Americans are obese: https://www.usnews.com/news/healthiest-communities/articles/...

When you add in all the other things that count as comorbidities here, you're probably looking at like 75%.

badfrog··on In 4 US state prisons, 3,300 inmates test positive, 96% without symptoms
The key part of that press release is:

> As of 24 April 2020, no study has evaluated whether the presence of antibodies to SARS-CoV-2 confers immunity to subsequent infection by this virus in humans.

The most likely thing is that it does mean immunity, but the WHO isn't going to say that without clear evidence.
