Adversarial review with respect to the veracity of the paper author? Unless you're making claims that would upend the field, no, it does not involve any of that sort of review. "I spent 1000 hours taking notes in a dog park" is not an extraordinary claim.

We're saying the same things back and forth to each other at this point and can probably wrap it up.

> Mirror sells you the equivalent of a beautiful, giant iPad that hangs on your wall for $1,495. Then, if you pay a $39 monthly subscription, you can use a mobile app to turn the Mirror into a fitness class. Both on-demand and live classes are available for everything from yoga to boxing.

Or you can just watch fitness classes on YouTube for free?

I don't think the issue is democratizing stock trading.

The issue, as I understand it, it's that Robinhood's UX has crossed the line from "easy, functional and usable" over to one that employs similar psychological tactics that social media, casinos, and lootboxes employ to keep users engaged with their product.

I'm not passing judgement on their implementation, instead likening it to similar pleasure cycles that lead to addiction like behavior in the aforementioned products above.
Launch HN: Meeting network Undock out of stealth
Hi Hacker News! I'm David Co-Founder of Undock. Scheduling is a pain and meetings are a drag. We stripped down every component of a meeting and reimagined what a seamless end-to-end experience would feel like.

Here's the first piece what we've built:

-Predictive Scheduling. Intelligent meeting time suggestions, wherever you work - starting in email.

-Privacy. Undock will only show the top few times on any given day that works for everyone - not your entire availability.Create an account and set to private and never answer "are you free?" again.

-Mutual Availability. We are able to perfectly match mutually preferred times filtered through everyone's scheduling behavior, preferences, and availability.

-Workflow. Schedule right from your inbox, no calendar checking required. We built in interactive conferencing with agenda+notes on screen.

-Real-time availability and status in the next release.

We're building some pretty interesting AI models around the project and I hope to be able to share soon.

The whole Undock team is thrilled to be announcing our release on Product Hunt today. We've lifted the waitlist for 24 hours. Join Undock and let me know what you think.
It's easy to end up ahead if you buy diversified index funds and hold them for a long period of time. Stock investing should be boring. The bigger issue is people want results now and not in 10 years, and that's when the speculative investments begin. People need understand that's not what the stock market is, and that strategy is very likely to end with having the rug pulled under you.

Ok, so...what if you _don't_ pay a $39/month subscription fee? Does this $1850[0] mirror do anything standalone? I think the answer is either no or yes but not much, but I can't tell.

[0] - Buying the $1500 mirror requires you to also buy the $100 "starter pack" and shipping is nominally another $250 without the promotion. Though for all I know the promotion is just always happening.
I recommend ignoring this misinformed WSJ article and reading this: https://www.kalzumeus.com/2019/6/26/how-brokerages-make-mone...

I don't know how to flag this thread to the mods, but--hey mods, can we lock these comments? It's disheartening to see threads on women/minorities in tech on Hacker News get strong, negative reactions from the community like some of what's written here. I would hope the forum can hold itself to higher standards than what I'm reading here.
This is because people in the US are used to dealing with legislation that means almost nothing until it gets interpreted by the courts, and no one wants to be that first test case so their lawyers take the worst-case approach. Just like many years of effort have been expended on just one paragraph from Sarbanes Oxley.

Second is that there is an opinion some have (based on some recent cases) that European courts hate American companies and will throw the most extreme penalty at them that they can get away with.

Third, from an end-user's standpoint, who here isn't sick and tired of having to click on the "Accept cookies" link all the time? Personally, if I have issues with specific cookies, I'd rather handle that automatically via client-side techniques.

A weakness will not come in the form of "it's suddenly broken". It will be a slow decline of worsening performance. Even quantum computing will be moving forward with a gradual rate of growth in Qubits.

At some point during this transition, it will break and they will have to transition. It will not be hard to create an new RFC for that task. It will be hard to replace all of the implementations in the field. We are getting better at this with our experiences in TLS but it is still somewhat painful.

Crypto agility can be really nice but it can also be messy. Sometimes it's best to be opinionated and sometimes it's easier to just be flexible.
To expand on this, Robinhood offers instant gratification as well without requiring a wire transfer. They have "instant deposit" limits that allow you to start an ACH xfer and use the money to buy options/stock within a few seconds. Most brokerages require the multi-day ACH settling period before you can trade.
This analogy makes no sense. You can't lose more than you brought to Vegas. When trading, you can.

I suppose it's more of an indictment of trading stocks in the hands of a newbie, but RH is customized for newbies (low cost trades, fractional ownership, gamification) without (anecdotally) all some of the guard rails that more mature brokerages have. Also, I've read that RH has/had "a bug" (as described on Reddit) where an inexperienced trader could overleverage. I can't see how this risk profile is profitable for RH, especially if they specifically aim to have a large portion of the newbie trader market.

Twenty years is young, but is there a particular age at which someone should be "allowed" to lose money playing with stocks / options? If the minimum age for opening an account if 18, should we put further restrictions on saying, for example, you can only sell puts when above 21? There are only so many restrictions we as a society can place before it starts severely infringing on personal freedom.

This isn't very acceptable to say at the moment (hence the throwaway account), but it seems like it would make a lot more sense for preferential treatment to come earlier in the pipeline. That is, instead of VCs using race as a major factor in determining who to fund (especially 1M+ rounds), race and other similar factors can be used to help provide training, networking, and other opportunities that help give historically under-served populations more of a fighting chance to someday be in a position to raise funding.

This is even more unacceptable to say right now, but many of us white males get ignored by VCs and we know it isn't because of our race or gender. It's because VCs won't fund you if they don't think you'll make a 50-100x or more return for their LPs.

It's a call option on increased home gyms that use mirror. I don't think the correlation between increased home gyms and increased use of mirror is as strong as the article suggests because the driving force behind increased home gym use today is also driving a recession that might be enough to influence consumer behavior towards purchasing items for a home gym based on a value per dollar analysis. I don't know if an approximately $1500 + $500/yr magic mirror that could probably be replicated with a camera, a sensor, a small chip, and your existing TV fits well with that kind of purchase decision making.

Yes, this is exactly right. The truth about HFT is that it has materially reduced the effective trading fees for retail investors across the board.

> the cost basis of trading with you is lower than with trading with the broader market

But this is exactly why Robinhood is bad. Trading with you (a retail investor) has a lower cost basis because retail investors are reliably less sophisticated than institutional investors. Therefore: an institution will pay to take the other side of a series of trades with you because it knows you aren't sophisticated, so it's likely to win in the long run.

From there, follow the incentives: Robinhood is incentivized to sell more order flow; which it does by increasing its trading volume; which it does by making trades easier. Robinhood is also incentivized to increase its net revenue per trade; which it does by increasing the price at which it can sell a given volume of order flow to institutions; which it does by making its average trade less sophisticated.

In summary: The most obvious way for Robinhood to optimize its revenue is to get its investors to make lots of bad trades.
A lot of things look suspicious if you've never noticed them before and have no frame of reference. Official statistics have always been revised over time, and any given person may or may not have ever noticed, and nothing forces the media to notice or be consistent about it.
Huh, you shouldn't, because there's nothing intrinsically wrong with a mullet. It's not awful, it just probably doesn't serve the function we expect our haircuts to serve (it might, for the right kind of person, of course).

The issue is this analogy absolutely doesn't fly. I sincerely hope software developers don't treat the UIs as haircuts.
I can see this being a good business, for the reasons described in the article. What I don't like about the fitness industry is the concept they are all implicitly selling that you need to go through an expensive intermediary to access your body.

If you want community and pre-crafted workouts, you could drop $20 month on Parkour Visions[1] for example, and help support a real community of people instead of some mega-corp. If you just want to workout at home you could drop the $1500 entry price for Mirror on a fantastic home setup. Or you could drop $50 on some gymnastic rings and head to /r/bodyweightfitness Or you could join a local club doing whatever floats your boat.

Late season chunk of mowing down summer crop, cover crop seed broadcasting, spring mowing, primary and secondary tillage and bed prep as one service. All of this can be automated with existing implements.

That’s a 5 month chunk of field work I can outsource to a Robotics As A Service type outfit. I like to divide chores by seasonality.(that’s how a farmer like me would see it..an engineer might not see that as optimal). It doesn’t require my knowledge or skill, it just needs horsepower. That’s capital and infrastructure cost and maint/labour expenses I can consolidate and probably will save.

It’s a diff set of automation when growing season starts. Of course, that flips when a farmer has winter/fall croppings.
it is that simple, however people don't want the responsibility.
We recently published a study on the podcast market based on Apple Podcasts [0]. I'm surprised by the numbers they claim as we see around a half of those numbers across Spotify and Apple, but we deduplicate them, so maybe that's why.

In any way, very interesting statistics.

A couple questions:

* does it support email automation (change component state by sending email)?
That is not true. The market makers buying the order flow are bound by the National Best Bid and Offer (NBBO) according to Reg NMS. Which means they cannot fill you at a worse price than the NBBO. However, there is a lot of liquidity on venues that are not part of the National Market System. A good, real broker will find you that price improvement, and pass it through. The MM buying your order flow will not, and will pocket the difference.

So, let's say you are trading 1000 shares. Normally, you might pay around $10 for that with a real broker. Now you execute that same trade at RH (or some other zero-commission broker), and let's say your average price is just 2c worse than what the other broker would get you. Well, now you just paid $20 for your "free" trade. And this gets worse for odd-lot orders (those that are not multiples of 100 shares). Because with those the MM is not bound to the NBBO, and can give you an even worse fill. Given that a lot of these RH accounts are presumably rather small, that likely applies to a decent amount of orders executed.

> the cost basis of trading with you is lower than with trading with the broader market

These are market makers; they don't take directional bets, hence this is irrelevant, as they only trade in a reactive way while trying to maintain a neutral book. What you are presumably talking about is toxic (i.e. informed) vs non-toxic order flow. Having a big player, who knows more than the MM, is what they are afraid off, because they can lose a lot of money by being on the wrong side of the market. They know that retail traders are unlikely to be informed traders, hence their order flow is less risky. However, the volume retail traders are moving is a drop in the bucket compared to what instis do.

Yes - because when I say "without breaking Chromium", I mean that Chromium wouldn't work at all because it wouldn't be installed following an upgrade, as opposed to some things you don't like about how the Chromium snap works but don't apply to the majority of Chromium users.

Edit: you seem to be conflating your disagreement on Ubuntu's choice to move to shipping Chromium as a snap with a technical detail on how the upgrade path for users was achieved. I understand you disagree with the former. The claim that this is about "make it some "universal installer"" is entirely false, and I'm simply pointing out why. Downmodding me for disagreeing with the former is doubly inappropriate here.

Thanks for that, from your reference:

"Why Robinhood earns more than the discount brokerages for order flow is readily apparent: their product encourages options trading. This is bad for customers, principally because the supermajority of Robinhood customers do not understand options trading and the risk/reward calculus for them is even more borked than it is for the vast majority of people who engage in it. The options trades they engage in are also less liquid, and so have higher spreads, and so are more lucrative for marketmakers, "

My experience in trying to raise capital is pretty similar to the author's, and I'm a white guy. However, I don't think that detracts from her point.

If the system were more meritocratic, the demographics of people being funded would more closely match the demographics of the world. But it's actually a game of personal connections, theater, and psychological manipulation that has little relation to competence in most business domains.

I think VC (and financial) culture in general is totally broken and far from meritocratic, unless you feel that getting good at the wealthy-capitalist-image-of-success-signaling metagame is a measure of some kind of merit.

"Evil" is subjective and too broad (most of it has already been outlawed anyway and that works: e.g. a competing business is going to think twice before DDoSing you as they know they are doomed if that gets discovered and proven). Surveillance, however, is a much more specific thing. Stalking people already is illegal for people, it should also be made illegal for companies.
Well, is the counter true? That investing should feel like a corporate sludge, overcomplicated to anyone who isn't lucky enough to have someone to show them how?

Investing is scary for most people. I think a positive spin is that Robinhood makes it so groups of people underrepresented in stock trading can participate. The stock market already is a game, and it's being played by rich people making themselves richer. Isn't it cool that a 22 year old with $100 can get involved, and it's not just old rich people who benefit from the system?

The stock market is soaring, despite millions being out of work in the US. The US has two different economies, and I'm all for anything that gives the latter group the same tools the former group has.
