Here's an analogy I once heard from Matt Andresen (founder of Island, one of the major early electronic exchanges). Equity markets are like a high-end clubs in Miami. A club that doesn't make any effort at "face control" at the door will find that it's ratio of guys-to-girls will continuously skew higher. And both groups will eventually stop going to any venue where the guy-to-girl ratio is persistently too high. However guys generally are willing to pay more than girls for entry, so it's a balancing act between maximizing short-term revenue and long-term brand value.

Similarly in any given market there's the ratio of informed trading to uninformed trading. Generally the former are large institutions, and the latter are small retail daytraders like the Robinhood customers. Since active management is a zero sum game, a venue with all informed traders is not a place you want to trade at.

By law the public exchanges are not allowed to segment order flow. Imagine a club that's legally prohibited from discriminating based on gender at the door. As you can imagine, the ratio at these venue is extremely biased towards informed traders.

Dark pools and internalizers are not bound by that restriction. However they're legally obligated to meet or beat the best price in the public market. (More on that in a second.) Retail brokers like Robinhood are essentially like club promoters, whose job is to get paid for bringing as many pretty girls to these venues as possible. And on the other side the informed traders at these venues (usually just the internal prop desk) pay big money for the privilege of trading somewhere with such a good ratio.

Is this a bad deal for the girls being herded by club promoters? To a first order approximation: no. At the very least they're getting free entry and drinks, instead of paying listed fees at the public venues. Sometimes they even get other perks like free meals or zero-commissions from the promoter. Still it feels exploitive because the promoter is making far more money off the girls than any fringe benefits they're getting.

As a second-order effect, the segmentation may degrade the overall ecosystem. Eventually all the girls wind up at the private clubs, and the public ones become ~100% dudes. Analogously the public lit exchanges have become highly toxic. Which is bad because market makers set prices based on the quality of the flow they interact with.

Remember that price protection on dark pools is based on the best price available at the lit exchanges. This creates a negative feedback loop. Dark venues can improve on prices at lit exchanges by segmenting order flow. Which forces lit market makers to worsen their prices. Which gives the dark venues even more of an advantage, allowing them to price out even more desirable order flow. Which then makes the lit order flow even more toxic, and the public quotes worsen. Which then drives even more flow to dark pools and internalizers...
This is wrong on several levels. First of all limit orders place a limit on the worst case price that can be executed but SEC rules impose a duty to execute orders at the best price. If there's a $100 buy order and the best price is 99 dollars, then there is a duty to fill the order at 99 dollars.

Second, the allegation made by the SEC, for which they most likely have very strong evidence, is that Robinhood didn't fulfill its duty to execute orders at the best price to the tune of some 30 million dollars.

Creative coding is my hobby, and I have gone back and forth with graphics and audio. I started with Processing back in the early 2000s, but I have since moved on to Extempore [1], and more recently, Nannou [2].

I like Lisps, and Extempore has two languages: Xtlang a low-level language, and a scheme for higher-level programming. You run the compiler as a service (CAAS) and you livecode and hotload your changes. You can program music/sounds at the note or DSP level.

I started learning Rust and stopped. Then I started playing with Nannou, and I am making good progress and having fun. The compile times can some times interrupt creative flow, but it is getting better. Extempore is great at hotloading changes.

Some more esoteric but fun experiments are ok/ike [3,4] by John Earnest. They are based on the k programming language. I personally use APL/J, but John has really done a great job here for creative coding and array languages.

Looking at these examples, I guess I am jaded by these types of experiments except the last one (neural network imagery from left screen objects). I saw many interactive things done in the last 15 years with interactive "pets", "creatures", etc. to the point where you had them at malls all over (kids stepping on floor-projected fish to scare them). We had a wall of flipdots or sequins at my last job in 2012 that used Kinects to track people and then silhouetted them in black and white as they moved. The combination of the mechanical dots flipping, and the black-and-white moving image was cool. I forget the company that made it. Not to say it is not entertaining, art, or creative coding, but I find myself looking at a piece and thinking is it strong on art, weak on tech, vice versa, or somewhere in the middle. For me, I like when it is very thought provoking and uses either newish tech or existing tech in a novel, unexpected way.

I did a bit of experimentation with different filters for a DIY build like that.

Setup: I tried out a bunch of different air filters in a medium-sized apartment. Two objectives: how fast PM2.5 is removed, and down to what level can it bring down PM2.5.

From worst to best:

* Nordic Pure 20x20x4M15+C MERV 15 - the carbon layer absolutely kills airflow, doesn't work

* Filtrete 20x20x1, AC Furnace Air Filter, MPR 2800 / MERV 14 - works okay

* Nordic Pure 20x20x4 - works well

* Lennox Corporation X7935 20X20X5 MERV 16 - works the best. This thing is an absolute beast in terms of filtration performance; significantly lower steady-state PM2.5 readings during the California fires.

Test equipment: Awair and Plume Flow v2.
I'll add that the main tools I know of that might be used in this field would be:

XZ/LZMA2 has the problem that it slows down a lot on incompressible data and can even choke pretty badly on compressible data, which Yann Collet's algorithms (LZ4 and ze standard) don't do nearly as much. This means zstd can be used indiscriminately, while LZMA would frequently need some sort of qualifier to avoid processing incompressible data and the associated loss of performance.

To put some numbers to this, on the machine (>10yo laptop) I'm typing this on:

zstd ~500 MB/s ~250 MB/s ~70 MB/s

It made me rethink the premise of my question.
Also, just adding onto my own post, I worked on a trading desk for a large bank. Shortly before I arrived there was an issue with order marking (the details of which aren't as significant and were caused by a genuine mistake). The SEC made us go through every trade the desk had ever handled and identify which orders were marked incorrectly. It was so tedious and painful that the bank wanted to settle and pay a bigger fine if it meant not having to deal with all that nonsense. The SEC were unyielding. The moral of the story is that there is no negotiating with the SEC once they decide they've had enough of you. I'm not sure to what extent RH have institutional customers but institutions have a fiduciary duty to seek best execution. RH are on a real legal ledge here. I wouldn't be surprised if this is just the start of a very challenging era for Robinhood.

Seriously, AMP needs to die as the power-grab over the internet that it is.

And honestly, the worst experiences I have had with AMP was on poor connections.
I think most people do this thing of wanting everyone to try it for two reasons:

1. Humans routinely make the mistake of thinking that what works for them will work for everyone.

2. The world is full of assholes who give people a really hard time for being the weirdo doing the weird thing, even if it isn't hurting anyone at all, so people want everyone to do it to try to defend against the negative consequences of being the weirdo that people will give hell to for simply being weird.

And yet even vegetarians can't all get on the same page, which is part of why we even have the world vegan to distinguish some subset of extremists from the rest of them. Similarly, there are myriad sects of Christianity because even people who all agree that they believe in Jesus Christ can't get on the same page about a lot of things and Islam is an extreme example of that: Just as Christianity grew out of Judaism yet it seen as distinct from being Jewish, Islam grew out of Christianity.

A man who grew up Muslim told me Jesus Christ is one of the major saints of Islam. It does not entirely eschew the ideas of the Christian Bible, it just believes in and celebrates a more recent prophet, the Prophet Muhammad.

Muhammad ...was an Arab religious, social, and political leader and the founder of Islam. According to Islamic doctrine, he was a prophet, sent to preach and confirm the monotheistic teachings of Adam, Abraham, Moses, Jesus, and other prophets.

https://en.wikipedia.org/wiki/Muhammad

I have zero fear that all of humanity or even the majority of humanity will start consuming an entirely beef-based diet any time soon. I think it is high time we got over our delusions that all humans everywhere will ever be on the same page at the same time on any given topic and embrace the fact that people eat different, people express spiritual beliefs differently and so forth and it's actually okay and for the best to let some people have their extremist diet without treating them terribly for finding something that works for them and without acting like that needs to become the new norm for everyone else as well.
That's usually how regulation works. Regulation is a moat. You want it to be really really harsh and then be one of the first few on the inside.

Because by adding a flat startup cost to an industry you make it impenetrable to upstarts. Then you can use a venture-funded company to get inside the moat. But once there are a few inside, the next person investigating will realize that if they also enter the moat everyone will be commodified. They will lose their money too.

They'll have to compete and like Thiel says in Zero to One, you don't want competition.

Regulation is good for protecting your business and for helping big companies survive upstart disruptors.

What evidence is there that U.S. food is safer than Japanese food, or even say Canadian food?

I don't have strong evidence but I don't regard U.S. food to be particularly safe relative to most first world countries. It's not terrible by any means and you're right in that you won't get any immediate damage from anything you eat, but I suspect most other first world countries have food and safety and health standards that result in better health outcomes over a long period of time compared to U.S. food.

[EDIT] After doing some minimal research it appears my intuition is correct, at least with respect to foodborne illness, the U.S. is certainly good compared to poverty stricken nations, but compared to most of Europe, Canada, Australia it has much higher rates of foodborne illness:

https://en.wikipedia.org/wiki/Foodborne_illness#Comparison_b...

The deaths in the U.S. is the highest, but what's even more interesting are the hospitalizations. U.S. hospitalizations are among the lowest and one has to wonder why that is given that it has the highest death rate. It wouldn't be unreasonable to suspect that because of how expensive the U.S. health care system is, Americans who do get sick avoid going to the hospital altogether. That is admittedly simplified speculation on my part, but it's a starting point for further investigation.

Hi!

I think all of your options are viable and smart. In the end, it'll all boil down to what makes more sense to you and your gut.

Here's my take.

1. This option will probably get you any job the fastest. While there are many who've started in PM by landing an APM or junior PM role, most PMs I know have transitioned to it from another position. Here's an article on How to Transition from Engineering to Product by Rubrik's Product Manager you might be interested in: https://bit.ly/2WoSS3P

2. This is also a good option, and I wouln't be too judgemental about it. Once you have a PM's title, it'll be easier to gain the necessary experience to transition into a company you like more.

3. The startup life is not for everyone, but it was for me! Entering a startup will always be a gamble. But if things go well, they could turn out great!

4. I was the PM of Product School when we began. I don't regret a thing. Still, i don't see why you can't start your own thing and work as a PM at another place simultaneously. Here's a resource about side projects you might like: https://bit.ly/3mr4fD6
She also doxxed an HRBP despite having no evidence she was involved during Gebru's firing. I do think she comes off as more passionate than "toxic." a lot of otherwise good people say regrettable things. My issue is that activists will take her accusations of racism at face value, but will dismiss anything outright ridiculous as irrelevant. You can't have it both ways.

The two are not exclusive. You can make money writing non-free software (or doing something else entirely) and write free software as a hobby.

Well clearly something has failed when some countries have the pandemic under control for months now, and EU is riding waves.

Or we want to ignore success cases? Because neither the media or governance talks about it, don't even mention that are countries in economic recovery and they match countries that have the pandemic under control.

It's like living with the virus is bad for the economy.

I think a big part of it was public discourse, some faced this pandemic has a battle that must be won, others took it has an inconvenience. This second group, the majority, then went on to face issues like individual rights crises that resemble something like everyone is entitled to their RIGHTS, but somehow they forgot about DUTY and RESPONSABILITIES.
"Free-as-in-beer" only makes sense if the customer is e.g. a student. Now that I have a real job and manage people, it's "free as in $200/hour employee time instead." It's like providing the ingredients for beer for free, and people can have free beer, if they agree to brew it themselves.

I want the free-as-in-freedom since if the vendor goes under, I can pick up the pieces myself. If my vendor goes Oracle and decides to milk me, I can find an alternative supplier.

I don't want free-as-in-beer because I'd rather pay a vendor $10 or $50 per month or something than pay my IT staff $100 or $200 per hour.

I'd also rather pay the original author $50 per month than pay an off-brand hosting company $25 per month because (1) I'll get better support (2) I'm not a douchebag.
