"But, if a composite is full of a measure that’s biased, how accurate is it going to be?"

Does it matter if the measure is biased, if you're measuring over time and looking for comparative differences?


When I read the article, this exact question came out as borne out of genuine curiosity justifying the need for measuring and comparing stuff, not a rhetorical question aiming to dismiss the thing.

And indeed, down the road, the article says:

> “There’s a lot going on between when the heart beats and when the blood gets all the way to the arm or wrist, what’s called pulse arrival time,” Tenan explained. “By simulating that and knowing what’s happening at the heart, we determined what’s being measured with the consumer wearable is different. It’s not to say the consumer wearable is bad or not useful, it’s just not the same.”

As in, electric signal ECG/EKG at chest level and blood flow PPG at finger/wrist level factually are not the same measurement, and asking "do they somehow relate in any way?"

Then the question is about the difference between RMSSD and SDNN/SDRR, and here this article (2022) explains it well:

https://tryterra.co/blog/measuring-hrv-sdnn-and-rmssd-3a9b96...

And answers TFA's question:

> “I don’t fundamentally see any reason why any of the wearable companies should be using the RMSSD measure

with:

> RMSSD is considered the best measure for short-term variations of HRV, but still a robust measure for longer-term analyses, with typical use cases for tracking stress, sickness, training, and recovery.

> SDNN is more useful for longer term cardiac health trends and analysis.


This already kind of happens. There is a right wing commentator who blocked me as I kept fact checking his posts.

However, if I create a list and someone on that list retweets the blocker's post, I can see it.

Clearly Twitter can't be bothered to implement blocking properly, so they've taken this step to "unblock" all content.

At least it is consistent.


It doesn't help that the pens look like they have a full dose of liquid, but the dispenser mechanism doesn't allow you to get to it.


I want to know how these people are in the UK legally.

To get a work visa you need to be sponsored by an employer. I struggle to believe UberEats and Deliveroo are sponsoring people from Brazil to come to the UK.


Discussion on Reddit suggests there is account sharing happening. Somebody with the right to work signs up and somebody else does the deliveries.


The books weren't accurate though.

Autonomy sold a lot of hardware and booked it as sales, but hide the costs as marketing.

The also signed deals with resellers and recorded it as sales, but without actually selling software to the end customer.

This made their proprietary software look far more valuable than it really was.

That's why the CFO spent five years in prison for fraud [1] and Lynch lost a civil suit in the UK [2].

I wonder if there is a technicality in the wording. It says "Ambulances have been called out" or "called to" it doesn't say they "attended" the warehouses.

999 operators will triage and prioritise ambulances based on the symptoms being exhibited.


I'd never heard of broadcast.com before, it is the inspiration for ROI (Radio on the Internet) and Russ Hanneman?


Probably! It was literally putting radio broadcasts on the internet. Tuning in to a radio frequency of a sporting event far away was avant garde and wanted by many. No idea why Yahoo needed to buy someone's janky website with an idea I just explained in 1 sentence, but yeah Yahoo managed to tank it from several billions of $ down to nothing in about a year.

Coulda been the first music streaming service. I hope someone has the minutes to those Yahoo board meetings and makes a cartoon out of it.


They didn't actually receive $445m in cash money though, surely? It must have been contingent on them having a working product, IT MUST????


"Having a working product" is often "too late to invest" in startups. It's just part of the culture. If you want to invest in somewhere that actually makes pizzas, you can buy an Italian restaurant in any city in the country.

https://www.forbes.com/sites/jackkelly/2022/12/05/early-vent... : in some sense, the real product, the hugely profitable one, was "the idea of a pizza company".

Or, if we look closer, the idea of a packaging company. They did indeed raise over $400m actual cash. https://www.crunchbase.com/organization/zume-inc/company_fin...


Exactly. And almost everyone I knew who got discount boxes simply decided what recipes they liked and then bought the ingredients from the supermarket for half the price.


Especially when they post their recipes on their website.

Are those blob storage options significantly cheaper than Google? I fear we are being pushing down a GCP route as it is what out consultancy know, rather than the best solution.


R2 would probably be significantly cheaper because they don't bill for bandwidth, but S3, GCP storage, and Azure storage would likely be in the same ballpark. Blob storage is a commodity service, so the major providers mostly match each other's prices and features.

If you are already using a particular cloud provider for the web application that will be accessing these documents, you should use their blob storage unless you have a compelling reason not to. Communication between a cloud provider's compute and storage services within the same region will have minimal latency.
