Simple. Find your dot on about 10 PDFs, interpret a handful of weather variables, know the safety tipping points of each, don't get it wrong or you may be injured, and check back every 4 hours! Easy.

I imagine everything is being analyzed but given that cheating in 11 online tournaments is enough to invalidate someone’s career it makes for an appropriate topic of article.

I get that. Just checking I had it right that this is ~not really the analysis we most want.

Just to make sure I read this right: he most likely cheated in 11 online tournaments from 2015 - 2020.

Why not analyze his recent and over-the-board games?

Quick question. Does anyone else get annoyed seeing the current temperature being greater than the high temperature for the day? Same thing with the low.

I’m not sure what it means - maybe the weathermen want you to know what they guessed? I’m not looking at the weather as a sports book of betting entries, I’m looking at the weather because I want facts.

You’re comparing a measurement to a prediction (current temp to high temp).

But yes! It’s very annoying.

There’s not a clear and simple solution though. You could increase the daily high, but then hourly data would never show/predict the daily high. Unless you made the current hour prediction = current measurement. But what if the prediction for the hour is 90% chance of rain (starting at say XX:43), you wouldn’t want to just override that with 90°F and sunny.

In addition to this the forecast for the day could be "Rain" but the hourly forecasts often reveal it is unlikely to rain for most if not the entire day.

So? That’s statistics. In 100 years you would predict one 100-year flood to happen, but each year the odds are unlikely.

I started with and was a Wealthfront customer for many years. I'm appreciative and credit them with starting my education and understanding on investing.

What caused me to leave?

- They aren't global portfolio aware. Bonds belong in tax advantaged accounts, then taxable. If you've maxed out your 401k/IRAs in Bonds that $ as an absolute percentage should be accounted for in your taxable portfolio construction.

- They don't let you opt out of asset classes. Aka I don't want additional REITs because I have RE exposure already.

- They overly hype tax loss harvesting. It's good to have, but a byproduct of portfolio management not the goal.

- They launched and pushed risky products as a way to increase their fees.

Once you understand what's going on under the hood this isn't complicated to manage yourself with a few ETFs/MFs.

(The direct indexing is awesome and would love to have that back)

Why do bonds being in tax advantages accounts? My gut would suspect the opposite, since on average stocks will have higher return so you'll want them getting the tax break.

If it means less-buggy products, let him stumble all he wants. I'm tired of billion dollar companies charging me for betaware.

You missed the entire point of the article – the products are going to ship when the products are going to ship (when they are ready). Yet he's committing repeatedly unforced errors by promising dates he can't cash. Ask it this way: What's the benefit to promising a date early, especially one you can't hit and sully the launch of?

Ruins the entire point of being secret as shit too.

Hi HN, this is my post which primarily serves to visually show the price umbrella of the iPad. It does that by showing the iPhone and iPod lines and explaining the methods Apple used to remove the price umbrella from those product lines.

I'd like your feedback, not only on the content, but also the site or anything I overlooked. Thanks HN.
