blahbhthrow3748··on Robinhood has lured young traders, sometimes with devastating results
> Trading with you (a retail investor) has a lower cost basis because retail investors are reliably less sophisticated than institutional investors

It's not about winning or losing, it's about getting "run over" by massive momentum. Retail investors move less volume and randomly take both sides of trades, so it's much less risky to trade with them. Conversely, large players can dump so much volume that they move the price against a market maker and decimate their revenue from whatever very small spread they usually collect.

> The most obvious way for Robinhood to optimize its revenue is to get its investors to make lots of bad trades.

Robinhood doesn't care whether trades are good or bad. A discount brokerage is a moving business, not a storage business (unless you count interest on cash balances, which Robinhood doesn't make much from). They make money from retail investors doing a lot of trades. Arguably that's against the interest of the investors because retail investors tend to make bad trades, but there's no malice on the part of Robinhood there. If all their clients made a lot of money presumably they'd use it to make more trades and make Robinhood more money.

You're kidding yourself if you think SF is a magical land where knowing to reverse a B Tree gets you promoted. Realistically managers promote people based on tenure, who they get along with, and what they ship. Being able to communicate and understand the problem space is way more valuable than some arbitrary technical "skill"
blahbhthrow3748··on A terrible, horrible, no-good, very bad day at Slack
In my experience the ops team will be constantly changing things and upgrading to keep all those customers happy, and they don't really care about your personal risk tolerance. They probably screw up a smaller proportion of the changes but they make an order of magnitude more and you can't predict what impact it will eventually have

blahbhthrow3748··on Magic hat leaves behind a transformed craft beer industry in Vermont
You're already behind the times, everywhere I look now lambic beers are the next big thing. Which is great because I love a sour. They seem to have largely supplanted APAs as the trend to chase.

That's not correct, it sounds like they got rolled.
blahbhthrow3748··on Mincome: Canada’s 1970s universal basic income experiment
A lot of people seem to think that having one stay at home parent is the ideal - surely both parents working and having no time to be involved in their kids' lives is not the solution?
blahbhthrow3748··on Revenge of the Suburbs
I live in a small semi-detached house that's walkable to the downtown of our city. I can bike to dozens different places to get take-out, we have a small private back garden where we can host guests, and we have enough space for two of us to work from home in privacy. We also actually see our neighbors outside every evening when we walk around.

There's definitely an in-between, medium density option that this article seems to ignore in favor of focusing on car-focused, isolated suburbs where everyone had 5 bedrooms and a pool.

I'm pretty sure "an NVidia" is grammatical here.
blahbhthrow3748··on How Much Should You Pay Your Engineers to Ensure They Stick Around?
The Netflix philosophy is basically that the job sucks and they will drain the life out of you but they pay above market. YMMV
blahbhthrow3748··on How Much Should You Pay Your Engineers to Ensure They Stick Around?
Bands are usually per level - if someone is sufficiently good you bring them in as a Principal/Staff/Magic Unicorn/whatever.

This leads to the same phenomenon where you need to work for 2 years to get promoted but if you jump ship your new manager will set your level in line with your salary expectations. And of course the levels are largely meaningless outside of compensation and office politics.

blahbhthrow3748··on 3K, 60fps, 130ms: achieving it with Rust
My first job out of school was doing product verification for the cameras that were used in those Cisco systems! It was pretty impressive, I think they managed to squeeze 1080p at 60fps over USB2. Had a lot of fun building jigs and testing setups to test the MTBF on a tight time frame
blahbhthrow3748··on Guix Further Reduces Bootstrap Seed to 25%
This is extremely neat but the name "gash" is... a poor choice. Gory in standard English, worse as a slang term
blahbhthrow3748··on Ask HN: Canada for tech jobs?
Salaries working domestically in Canada are quite a bit lower, but CoL can also be good. Shopify for instance pays ~150 for senior devs but in Ottawa or Waterloo houses are pretty affordable.

I've had some luck working remotely in Canada for US companies - tax treatment of stock options is worse and they typically have few or no benefits for Canadians. On the other hand, you can have a significantly higher take home if you find the right employer.

a) it is absolutely conceivable to write a cheque to yourself. For example, to move cash between bank accounts

b) the bank has a big database and a system of clearing cheques that ensures you cannot double-spend money by writing yourself a cheque. If you try to kite cheques by abusing the latency in the system they notice because it turns out you can just write that down in a central database too and it's pretty effective

blahbhthrow3748··on Fyifv: A Microsoft Urban Legend (2001)
My experience with engineers who made too much money in an IPO (not at MSFT) was the opposite - they mostly wanted to sit in the corner and play with whatever cool toys and have no clear job description. They didn't need to threaten leaving because they were furniture.

blahbhthrow3748··on Trump threatens to 'close' down social media platforms
Wait, to be clear you mean the language "Congress shall make no law" which clearly doesn't apply to Twitter? I agree it's unambiguous the constitution doesn't allow the government to restrict Twitter's rights
blahbhthrow3748··on Big data and the Roman census approach (2014)
I doubt the Romans actually had any influence on the design of these systems. The reason the author says the concept is "unfamiliar" is because it's immediately obvious and doesn't warrant a name.
blahbhthrow3748··on Loginsrv: JWT login microservice with back ends like OAuth2, Google, GitHub
You basically need to have a revocation list or rely on the expiration time being sufficiently short. JWTs are neat for a lot of things but I don't think they make sense as a replacement for sessions for that reason (where you control the server and the client and you want to authenticate users)
blahbhthrow3748··on Introducing Facebook Shops
A lot of Shopify's competitive advantage comes from being a giant, Canadian tech company. Similar to Blackberry before it, the government is extremely generous and investors price the stock accordingly. If Shopify moved to the States or was acquired by an American company I think it would take away that unique appeal.

Also the founder is an egomaniac and would never sell.

blahbhthrow3748··on Ask HN: I just started my first real workday, any tips?
Ask questions and be willing to discuss your thought process with people. Don't be afraid to try and improve things even if they've been like that a long time. Try and find something to work on you're genuinely interested in.

My first job out of school (8 years ago) was a pretty effective springboard. Unfortunately the secret to success was basically to be excessively keen and interested in doing anything and everything. At the time it was fun - I worked too much and I made myself look foolish at times, but I was junior enough that it didn't matter.

Now that I've been around for a couple years and I'm a little more jaded I don't think I could do it again. But if you're very keen I think just being enthusiastic and learning things will get you far.

The Odd Lots podcast is very similar and Tracy and Joe are also very funny. Matt actually appears in a couple episodes (he has a really deep voice I didn't expect)

Pseudoephedrine in Canada has to be mixed with acetaminophen, which is difficult to separate back out for meth cooking.
blahbhthrow3748··on Georgism
Sales tax fails to capture the accumulation of capital, so (1) is kind of bogus. If you make 100 billion dollars and invest it you and several generations of your family coild live comfortably without ever working and your tax burden would only depend on your spending.

A sales-only tax incentivized rent seeking, basically, because the rentiers pay the same taxes as the renters while accumulating capital.

blahbhthrow3748··on Ask HN: What's the biggest time waste on your workday?
Underspecified tasks. Companies like to pretend that devs should "own the solution" but in reality there's a lot of coordination involved and you can't just make things up. Trying to find a way to get feedback from everyone just to get started is a huge waste that someone like a product owner should handle

blahbhthrow3748··on Dev Degree: Behind the Scenes
You could absolutely work on Shopify without a CS degree. There's probably a 10:1 ratio of people churning out features versus people doing infra and tooling to support those devs.
blahbhthrow3748··on America is stuck at home, but food-delivery companies still struggle to profit
Shopify will wait until a partner builds it on their platform, see if they're successful, then acquire them. They've done it a couple times, they have tons of cash and don't need to take huge risks.
