Internet daytrading in the 1990s was an early version of Robinhood. You no longer needed to place trades with a broker intermediary. Commissions dropped from 3% to $8 a trade.

I know people who retired into daytrading, grad students who invested their living stipends In daytrading. Things calmed down during the 2002 recession.

There weren't unlimited resources. Each of the Pacific islands (except to some extent the large ones like Hawaii, which was settled late) got to carrying capacity pretty quickly after settlement, and populations were balanced through some variety of ritual warfare, cannibalism, infanticide, and starvation.

Plus, it doesn't take everyone doing it. It only takes a couple families in a couple boats, each generation, to hop across the whole ocean.
To me, statues represent history.

Not all history is good, and not all is bad.

Removal of statues, to me, is like trying to hide history.

Statues usually have some plaque describing who the person was, and what they did. Why can't that plaque say the guy owned slaves, or was a confederate general or whatever? Ya, these guys were on the wrong side of history, but there's still things to be learned.

One of the best military minds of all time, for example, happened to be a confederate. Should we learn nothing from this man aside from the fact that he was a confederate?
It is amazing to me if that the entire conversation on the thread is about her credibility, and not at all towards the systems that lead to blogposts such as these. It isn't one interaction, or one round or one app, these are system issues!

I think it is more interesting to discuss how all of the investor assumptions, ideas, pipelines, and teams, all are informed. And there isn't enough being done to deconstruct that. For example, what does it mean to say 'too early' to an under-represented founder? who is the comparison to? How many of your last X investments or team members came from Stanford or ex-FAANG?

Maybe YC can take the lead here? @mwseibel?

I don't totally disagree. But, at some point, "let people make whatever stupid decisions they want to make" turns into we should also be able to kick those stupid people into the gutter and abandon them.
Good luck with pluma! I agree CMS in the cloud has strengths such as backups etc. Just in my experience that cloud projects seem to have a half-life of around 5 years :)

I was thinking the same as you: Having an export to some format (i was thinking Hugo or Jekyll) to give people that assurance that there's a plan B if things go bad.

As for the hassle to setup etc, I totally agree! That's a large part of what my idea would solve. And even with technical skills it's a hassle, i agree - which is why i initially thought posing this at devs would be good. But now i think they tend to DIY these things so perhaps not a great target market.
There are a lot of things a metal lathe can do that other tools can't. But that doesn't mean a lathe is a good tool for everybody. In fact, it couldn't possibly be, because there are trade-offs between usefulness and safety. You just can't make a lathe that's safe for the casual user but useful to a professional user.
I don't understand the need for all of this obfuscation/gamification around the act of actually performing physical exercise.

What works for me regarding on-going daily exercise is rowing while listening to a podcast about something really deep (JRE, The Portal, etc.). It takes me exactly 60 seconds to get my shoes on, queue up a podcast and start into the rowing session. Anything longer than this would probably demotivate me to the point of not exercising regularly.

I strongly suspect the reason a lot of this fancy exercise gear is never used consistently is because there is always some UX annoyance that gets in your way - forgot safety key somewhere, need to update your treadmill software, have to review user manual, etc. In this attention deficit society, anything beyond 60 seconds might as well be tomorrow. You have to eliminate barriers to fitness, not create new ones.

A Concept 2 Model D rower can operate without electricity or internet. Its user interface is completely optional (assuming you already have the damper set appropriately). The mode of exercise is intuitive and easy to learn. These facts make it one of the most valuable pieces of exercise equipment that one can own. All you need is a can of 3-in-1 oil and you can make it last for an eternity. The only things you have to think about are your form and how much you feel like pushing your metabolic pathways. Everything else is optional. This is the best way to monotonically improve ones fitness. Consistency and ease of use. Distracting screens and wildly variable exercise regimes built upon social networking and gamification are moving entirely in the wrong direction.
This thing sounds more Yeats than Orwell:

> I just don't see these fad things Peloton, Mirror, etc. bringing people anything beyond short term novelty.

I’m not sure I would put the Peloton and Mirror in the same category. The Peloton is an spin bike, and does a good job bringing the spin studio experience into the home. Spin is fairly popular way to exercise. The high cost of Peloton is also still less than any spin studio I’ve been to.

Both have gamification which I think is useful. I like metrics, so the Peloton works for me much like power lifting does. The part of the Peloton I don’t care about is the community aspect, but my wife is pulled to workout because her friends have worked out and will see if she stops.
Maybe we shouldn't be throwing words like "addiction" willy nilly.

Is it really your opinion that the guy wouldn't fund his investments via credit card debt and then followed it up by borrowing $30k against his mortgage if only he used ETrade and not Robinhod?

Somehow, I really don't think so.
> I would love it if I could just write queries and it would automatically add an index or do something else for performance if needed, and possibly report back to me if a query I wrote has particularly bad performance.

Azure SQL and Amazon RDS do this - but they’re Cloud-hosted IaaS rather than on-prem.

On-prem SQL Server does have similar, but limited capabilities with its Query-Store feature - but I don’t recall any of it being fully automatic - at least not by default: which may or may not be a good thing.
My girlfriend wanted a Peloton.

I said okay but first we're getting a $300 version from Amazon. If you use it every day for 2 months and it isn't sufficient, we can get a Peloton.

We now have a $300 clothes rack. Luckily it wasn't $2000.

If you're the kind of person who doesn't work out regularly, a gadget won't make you work out regularly. It will at first. When the novelty wears off, it won't. Just like the impact every TODO app and productivity system has on me.

You must first become the kind of person who works out. Then buy the gadgets.
You don't have to use the material design stuff, you can just make your own components, all custom, just as you would on the web. Just replace MaterialApp with WidgetsApp at the root of the application tree.

> The meaning of "joins don't scale" is that they don't scale across database servers, when your dataset is too big to fit in a single database instance.

You're correct. However, most applications databases are fine with billions of records on a single instance. It's a rare application that needs the level of scale you're talking about. In other words, a typical startup doesn't, at least not at first ....

Virtual pub on a Friday, via Zoom, has been surprisingly successful.
Part of the answer I think is that we often underestimate the level of sophistication of people who lived a very long time ago. Polynesians were expert navigators, they had a lot of knowledge of things like wind patterns, currents, birds, the positions of the sun and stars... and knew how to use those to orient themselves at sea. Long voyages were probably dangerous, but they may well have had the means to turn back and return home in case they didn't find land. This article is really interesting:

https://en.m.wikipedia.org/wiki/Polynesian_navigation

Maybe discovering far away lands was to them meaningful for exactly the same reasons that it was later for the European explorers who rediscovered their islands...
I agree with you that "identity" has many attributes of which an email address is only one.

The problem is that in practice, control of the email address on record is sufficient to take over many modern accounts. Bank accounts likely shouldn't fall into this category, but most web sites don't have bank account level of security.

Hotmail created a hornet's nest of problems when they started recycling email addresses after 6 (or 18?) months of inactivity. It allows a quick "password reset", then the account is now owned by whomever controls the email address. Effectively, the identity is hijacked because control of the email address was most of the authentication mechanism. Queue the spam messages and fraud/phishing.

Also developing/managing a customer service tool which allows them to decipher these "takeover" events and ensure the person contacting them used to own the account is difficult and sometimes not possible.

Neither twitter nor facebook started with anything like the architecture they use today, nor did they have to, nor could they ever have known they'd need it or even what they would need.

You’re right that it’s a marathon not a race. But isolating the vulnerable (on a semi permenant Basis) is not easy or good for these people. With good testing infrastructure and contact tracing, we can minimise harm. We just have absolutely no definite idea who are those who are otherwise healthy who are going to end up hospitalised (say for my age group 30-40 males it currently looks like 1:500 will end up needing hospital support) and that’s even before you look at those who may do fine without hospital but still be carrying some serious consequences (ie original poster’s partner).

I for one would like to avoid getting this altogether
The data only include publicly accessible RSS-based podcasts, which is a very narrow definition of podcasts.

There are exclusive "podcasts" on Spotify that are not publicly accessible and not distributed via rss.

There are other forms of spoken audio contents that are publicly accessible but not distributed via rss.

Open RSS-based podcast ecosystem is less developed outside US, for countries with comparable (or larger) population.

There are many walled garden audio platforms in countries like China. For example, probably most of you haven't heard of Lizhi FM [0], a "podcasting" platform from China that just went public early this year. Most of its audio contents are not distributed via RSS.

Probably scraping with a sea of proxy IPs or a rented botnet

One could test this hypothesis by doing the same thing to it--spamming search queries from numerous IPs--to see if Runnaroo's IPs stop working (get 429'd or captchawalled). I don't really have time to whiteknight for G, but OP should be prepared for them to take notice. (Maybe create a global rate limit.)

I'm interested in how the ranking algorithm works because it seems really good.

Edit: Runaroo is now down. Looks like he was ahead of me on the global rate limit suggestion.

I was mostly referring to this bit from the article: “Notice how the model that has the lowest mean squared error is also the model that causes the most bias between groups for higher skill levels. This increase in bias cannot be blamed merely on the data. It’s the choice of the model that increases this bias which is the responsibility of the algorithm designer.”

My reading of the plots is that the difference between the groups seems to grow beyond what is present in the data. Do you not think this is amplified?

As for conditioning on a biased variable; this post uses a contrived example for sure. But the same thing happens with variables that correlate with the “naughty” variable (perhaps author should have explicitly showed this to drive the point?)

Removing all variables that correlate with “naughty variables” is a pretty difficult task itself without having something to detect the correlation and tell you. At least that’s been my experience.

1:34 The thesis at the start of Anybots

3:27 Wheels vs legs for telepresence robots

6:50 Why did Anybots make legged robots

8:04 What do you think of Boston Dynamics Spot Mini

9:50 Vertical vs Horizontal applications in robotics

12:24 A proof of concept proves to everyone what is possible, and emboldens copy cats

13:37 What would have happened to Cruise if GM hadn't acquired them

16:15 What does it takes to launch self driving car service like Waymo or Cruise

18:04 Benchmarks for autonomous driving performance

19:48 Why it's better to have customers hungry for a solution

21:06 How to overcome the challenge of rule based behavior planning, like Tesla doing end to end ML

23:42 How early stage startups should build hardware by focusing on iteration speed and tight customer feedback loops

26:58 Vertical vs Horizontal applications and their impact on iteration speed, like building 3D printed houses

28:43 What should hardware companies get done during the YC batch. Ideally cheat with teleoperation if you can

31:17 Why Tesla's approach to getting data from real drivers is very effective path to full autonomy. You need to figure out a business model that isn't bleeding money while you're getting data.

33:47 What Elon Musk gets wrong about end to end autonomy

35:38 What robotics companies would you like to see applying to Y Combinator?

36:36 Drone delivery is working well where people are more desperate. Generally technology is developed where need is greatest, and then moves more broadly to other applications.

38:50 We get accustomed to high quality, like the speed of delivery. The standard can always improve. How many more iPhones would people buy if delivery were every 15 minutes.

40:19 Speedy delivery for auto parts is a clear application.

41:38 How telemedicine can be much more efficient

42:32 Regulations in medicine make developing products far more expensive.

43:15 Regulation is like a fog of war which dramatically lowers iteration speed

44:50 Inaction causes harm, including an example of the cost of $1 parts and the tradeoffs for human life.

46:06 What do you think of Marc Andreessen's "It's Time to Build". San Francisco doesn't feel like the future. We need more experiments.

I think, and my experience was, after 16-weeks of daily excercise you'll enjoy it - expensive bike or not. My first attempt (20+ yr ago);was just running 30 minutes a day, 5d/w - and it was great, then work and life got in the way. Eventually I got back in to daily...at first hard but over the "hump" and now, I need at least 30 minutes

I'm glad you found enjoyment in health, but one doesn't need the expensive hardware to get there
This is a perfectly sane position if your actions only affect yourself. The issue is that your actions affect others.
Maybe. I was a Peloton skeptic, and more and more friends got them over the last year or two. Every friend who got one a) loves it and b) is still using it - often daily. I was fine going doing cardio pre-weight workout until the gyms closed. I finally gave in to the wife and got a Peloton and I understand the obsession now. It’s the closest thing to a spin studio experience in your home. The instructors are top notch, and the bike is a nice spin bike.

Now that I’ve finished my home weight gym, I will likely never start up my gym membership again.

> if you're absolutely sure you need to be planning to run at close to Twitter or Facebook scale one day, then yep, you'd better architect from the beginning not to use joins.

If your company end up being as large as Twitter or Facebook, you probably can raise enough money to overhaul the entire infrastructure to make it efficient in your custom scenario, which is much better than prematurely optimizing when you have 100 users.
Just to push back a little on one minor point: even if your goal is specifically strength, until you're quite far along you can get most of your muscle groups just as strong with bodyweight exercises as you can with weights. Resistance is resistance.

By the time you get to the point where you need weights to keep progressing, you'll be really strong. Bodyweight training also improves muscular coordination, balance, and flexibility as well, which all have major benefits. I highly recommend it for beginners--you don't even need to buy rings or a bar necessarily if you can find a good tree branch.
Yes and no.

“yes” because what clang did is a very good job, pretty sure it substantially faster than scalar code. Especially on newish CPUs like Zen2.

“no“ because from what they have currently for that particular test case, they only need a few improvements to make their code as fast as a manually vectorized version. Apparently, the compiler is already aware of the cost of RAM loads. They just need to account for these bypass delays between integer and FP execution units in their code generator.
Re-opening is a knapsack problem.

Your budget is Rt (effective reproduction number) which has to stay at or below 1.

All social and economic activities have a benefit to society and a cost in terms of Rt.

The goal is to get to Rt = 1 while maximizing the benefits to society. The problem is that covid is so contagious that many activities have a very high cost.

Seen this way, maybe it makes sense to throw bars and indoor dining out of the knapsack so we can put schools in.
