Thanks! Yes, the concerns you mentioned would also apply to PCA. What we've actually done to help alleviate this is a union of components from y-aware[1] and normal PCA to capture variables that are correlated to both the dependent variables and (hopefully) most of the treatment variables. This seems similar to the double selection approach you mention - the difference being that since we are trying to run this at scale for 1000s of treatment variables, running a feature selection with each of the 1000 treatment variables as the dependent variable isn't super feasible, so the normal PCA acts as proxy for this part of the double selection.

Regardless, we're never going to completely remove omitted variable bias, as we're never going to capture 100% of relevant variables. One way we monitor our model's bias is by looking at the error distribution between users in the treatment vs control. If these aren't similar, there's too much bias in our estimate of the treatment effect, so we wouldn't want to serve an estimate of the treatment effect for this variable to our customers.

The current product is in beta and we're working with some of our current customers to try to re-create our results with A/B tests. I'm hoping that by our GA release in the fall we'll have some case studies with specific examples!

Delicious news! Now we can have Wagyu everyday. :D
Yeah, that was my point. No kernel panic on a triple fault.

Though arguably, a hypervisor can dump out some useful state on a triple fault, as they actually tend to do. But that's not an in-band kernel panic, and in VirtualBox at least you can get a dump of that state without sending an NMI or otherwise disturbing the VM.
That is a fascinating perspective I'd never have realised by myself. Thanks.

You're a gift to horror/sci fi writers.
I feel for you man, I drove 4 hours from Sacramento to Palo Alto for a great start up job. I nailed the phone interview and thought all was going to go well. The first onsite interview went pretty well. The second part went south and my nerves got me. I really wanted the job but I blew it. I got good feedback and I'm working on interview problems. It was my first interview in 20 years but again I really wanted the job.
Yeah I broadly agree that there is a lot of confusion about capabilities.

Some years ago I was working somewhere and the management had caught the AI/ML bug and were obsessed with the idea of using ML to generate business "insights". They'd get some vague & unspecified data about a client's business operations, we'd input it into the ML and voila: "insights" about how to improve their business (and make us money)

They didn't know what these "insights" would be, they expected machine learning to magically generate them on its own.

I tried explaining that at a high level, ML can only really give you answers you already know are possibilities. It won't offer up some totally novel answer that you've not trained it for - i.e. you've got to know what the answers could be before you even start.

We got shut down by the parent company not long after that.
For those looking to learn more the full study is linked from the NPR report: https://science.sciencemag.org/content/365/6454/668

"We show that a portable exosuit that assists hip extension can reduce the metabolic rate of treadmill walking at 1.5 meters per second by 9.3% and that of running at 2.5 meters per second by 4.0% compared with locomotion without the exosuit. These reduction magnitudes are comparable to the effects of taking off 7.4 and 5.7 kilograms during walking and running, respectively, and are in a range that has shown meaningful athletic performance changes."

Note that "The entire exosuit weighs 5.0 kg, with 91% of the total system mass carried at the waist," so it might be a few more revisions until this is very practical, but it's still super interesting work!
The link doesn’t work, I’m interested to read it though.
That is not limited to data science. I remember the horror of an intern when he realised that real work wasn’t at all like solving neat little puzzles on HackerRank. He discovered that he didn’t really want to be a programmer after all...

>Provide additional mental health support for Googlers of color - especially following critical moments impacting their communities

This was a fascinating look into an entire different world, thank you. To work for a company that actually provides mental healthcare and then demand it proactively monitor the media for possible sources of stress on particular employees is a position of such breathtaking privilege I had to read it twice before it sunk in. Has this person ever worked somewhere half his coworkers are living paycheck to paycheck? Has he ever had a bad job in his life?
The root problem is that we consume too much energy and other resources, increasingly. Both per capita and in total. Our biological instinct is to grow in numbers as much as we can, and economical incentive is to sell (and consume) more and more. What can you do about these?
Please XOR your hashes instead of adding them! If you add them, you're losing bits on the low end. EDIT: No you're not. It feels like you should be, but with unsigned overflow, this actually works just fine.

This assumes of course that you're using proper hashes that make use of the full domain of the output type (a proper hash will have a 50% chance of any arbitrary bit being flipped by any change to the input). But if you're not using proper hashes, you're doing something wrong.

Because he got lucky. No, sacrificing everything for the goal does not always get you the goal. There's 1,000 Bukowskis out there, many better, and we'll never hear of them.

Sometimes you waste it all, and then you're supposed to look back and say, "Well, at least I gave it my all, and I just had bad luck." Yeah, that's really fucking comforting.
If you are going to eat out all the time, try to make it places that use whole foods like real chicken breast in their burgers. At least you're not getting all the processing guff that ends up in processed meat blends. Also give Japanese, Korean or Thai cuisines a go. You can eat pretty healthy and still eat out constantly with a lot of East/South East Asian cuisines.

Reviews aren't bad, but they don't necessarily stop bad apps, and they slow down good ones.

The worse part of approval delays is that they are almost never given time in development schedules made by project managers, bizdevs, marketing etc. They just absorb that few days into the dev time or take from testing etc.

In a way, having long app reviews, or delays to update, causes worse quality apps from having dev days or testing days taken from the app development cycle and rushed fixes just to get it back in the pipeline. This is a very common occurrence in app/game development. I wish it weren't this way but quality has to be fought for and it can harm the people pushing for it perceptually as 'slow'.

Basic heuristics on release for bad actors is enough, then upon launch have random reviews that check out what people are doing past the point. The problem apps are usually getting through the review by cheating and then turning on features that are dark patterns or malware type junk.

Any reviews over a day or two add to bad quality simply due to compressed timelines.

I can. There are a lot of Amazon employees. Many are probably happy with their job and unhappy to be constantly told that they shouldn't be. I think that I would personally be annoyed by all the think pieces unilaterally claiming that the job I chose was a sucker's game and I'm too dumb to realize, especially since Amazon is distinctly better than average as warehouse jobs go

This is not how climate balance works.

There used to be a relatively stable equilibrium in the climate. There have always, and will always, be many mechanisms contributing to the overall total radiative forcing.

We can’t reduce how much water vapor is in the atmosphere very easily. But methane, we can.

It doesn’t matter that methane has low partial pressure. What matters is the total radiative forcing, and every molecule of uncombusted methane has a very high radiative forcing in the atmosphere.
We may be hitting the point where societal impact is great enough that people don't necessarily accept "We can't do that at scale" as an out.
"My teammates always had something to say about everything. but when it came to the violent policing of black bodies, they were silent."

My guess is that they were afraid of retaliation and wisely chose to keep mouth shut. PC now is the new religion, especially in big companies. A few centuries ago, when religion was strong, engaging in a debate with strangers about whether the god exists would be a suicide: unless you say something along the few pre-approved lines, you would be reported and retaliated against.

It's a curious situation when black and white people see each other privileged: whites are privileged because "white privilege" and blacks are privileged because they receive special catering and are immune from many things that would get a white guy fired on the spot.

If I have a 32 bit current hash value-- for any possible 32 bit value I add, I get a different 32 bit value out.

Airbnb is a marketplace.Verified homeowners list properties. Airbnb dosen't involve themselves in the operations of the homes themselves like speaking to guests, making sure the amenities are well stocked,the property itself is not verified, no control on pricing and inventory.Even with everything they have done, there are trust issues from a local market perspective. (speaking from the experience of being an Airbnb host in India). This may lead to a unpredictable experience for travellers.

And if you want a more standard experience from Airbnb you would have to book a - Airbnb Plus home. Airbnb Plus is a DIY (Do-It-Yourself) model where set guidelines are given and the host has to adhere to the guidelines to maintain a Airbnb Plus status.The Airbnb plus program is yet to launch in India for leisure travel.

We offer a DIFM (Do-It-For-Me) model where we help hosts uplift their property standards to our brand standard via. a playbook that we have created. We help them with this process and also take care of technology back-end,marketing & distribution, operations in terms of guest communications etc.

For Travellers:
1. Experience - Significantly better and predictable experience for travellers.(Like a Zeus Living Home).
2. Affordable - $50 per night. We control the pricing and inventory unlike other marketplaces and OTA’s.
3. Accessible - All homes would be in scenic locations 2-5 hrs from urban cities, perfect for short getaways. Our competitors do not reveal the exact location unless a booking is made, which is frustrating for a traveller while planning.
4. Differentiated branding with a chic design and unique millennial voice.
5. Travellers need not choose between an authentic experience or dependable customer service and basic amenities.

For Homeowners:
1. Ease of converting a regular home to a branded Kipstay Home via. Our easy to execute playbook.
2. Product features - we provide branded amenities, marketing and distribution, pricing and inventory management via. A tech backend.
3. Higher occupancy rates (higher than 50%) due to Kipstay brand which directly increases earnings.
4. We offer a DIFM (Do-It-For-Me) model instead of DIY model which is time consuming and expensive

Younger people's understanding of how world works and what a person is like comes entirely from the internet.

The moment you try to break out of your internet and go meet new people, it frustrates the hell out of you that life isn't as cool and people aren't as witty as they are on internet.

And you start thinking maybe you aren't with right people, so you try to meet the cool people from internet in real-life and it's again same. The same people you enjoy on internet, you can't tolerate them for even an hour in person.

What internet portrays is only a part about a person (which they've edited then edited and then edited again).

What we assume life is like a Hollywood movie and yes retakes frustrate the hell out of us but life is actually the retakes.

Add a checkbox to show apps tjat aren't approved yet.

Disable it for people under 18.

If a user still wants to install the app point out the app isn't approved yet and ask for password.

There are a couple more things wrong here.

LEOs have access to tools that the public and corporations don't have access to, and the law prevents them having access to. By paying a LEO to access those tools the insurers are circumventing the will of the people.

Also, by paying LEOs to investigate a particular crime that means the insurer is effectively getting to pick who is investigated and who isn't. They should be able to deny a claim, and report what they believe is fraud, but the insurer shouldn't be telling law enforcement who to look in to. That's law enforcements decision alone, and payments muddy the water.

Paying for law enforcement is a bad idea. It changes the incentives too much.

In this case, Ecosia would still rant about it. They would only change their complaint text from "what about non-profit oriented search engines like us?" to "what about search engines nobody has ever heard about like us?". Interestingly enough, they use Bing API for actually producing SERPs, so basically this is a PR stunt for not getting free access to a marketing method that is irrelevant to user experience. While their claimed goal of promoting afforestation is rational/noble, I consider their argumentation in this case to be disingenuous.

> Also, the CEO purchased a whole bunch of shares before the report and again after the report. He is probably well positioned to know GE fairly well. It's not a necessary move on his part but it does signal some confidence in GE.

Couldn't this be seen as a PR move to do damage mitigation and earn market confidence? As you mentioned that it's an opaque company accounting-wise it'd be hard to evaluate this objectively but the CEO of a possibly fraudulent company buying stocks to earn the market confidence seems to be a very low price to avoid the possible side-effects if the allegations are true.

Angular (v. >= 2.x.x) on this is much simpler to understand as it manipulates the DOM directly. With the built-in dev tools of any browser you pretty much can inspect any portion of HTML, CSS and source code.
