Sounds like you didn’t believe you could fly.

I just really want to see where the numbers come from.

You know people self hosting email, I know people self hosting email. But that is certainly not the case for the vast, vast majority of individuals. For businesses, I have seen Exchange take over what used to be smaller hosts, and Google has broken into the small/medium business world as well. I have searched and searched and found nothing, but I don’t see why it should be so hard to do. Obtain a list of email addresses from some data breach (I dunno how but I’m sure security researchers do it all the time) then check their DNS to see what proportion point at big tech. My gut feel is that it’s a large proportion, but maybe that’s just the corner I work in.

email can be run using hundreds of servers on dozens of platforms even from your own house and interact with the email network.

It’s nice that it can, but the point of this list is is that what actually happens for the majority of people?

And from my experience, the answer is no, the vast majority of people use Microsoft or Google.

This claim is “Top Provider User Share: Google ≈ 17% → Score: 27/30”

Where does this number come from? Gmail alone claims 1.5 billion active users. Outlook.com has 500 million. But then you have to start adding up all the email users worldwide that are using services hosted by Microsoft (all the Exchange business customers), and the google customers as well (that may or may not be included in the Gmail figures). Then there are all the ISP email addresses that use these services as the provider.

I find it hard to believe that email is as decentralised as claimed here, and I’m really keen to see more data on how it was calculated.

The reason I find it so hard to believe is that when Microsoft fucks up (and given time they always do), a significant portion of the business customers I deal with get affected.

Kids that age shouldn’t just be able to use a computer unsupervised or have free access to a computer/console like that. Screentime is a thing and its important.

There is no indication that’s it’s free unlimited access. I don’t get how it being unsupervised is related to screen time.

I’d happily throw minecraft on a phone to a kid in the back seat of the car. I can’t see what they are doing, but I know that minecraft not on a public server has very little content inappropriate for a 5 year old, and what little there is doesn’t come up if you have peaceful mode on.

I’m not convinced that a 5 year old can’t grasp the concept of virtuality. Minecraft on peaceful mode is just giant blocks being picked up and placed. Even if it were true they don’t get that it’s virtual (that I don’t really understand how that could be true), I can’t imagine what long term damage could possibly be done by believing the blocks are real.

Even younger. The touch screen version is easy enough for a 4 year old or maybe younger, depending on what you constitute “playing”.

Now I think about it, I’m certain I’ve had this conversation, except it was cats not cows.

The process manager lets you kill any process.

You can also click the do it anyway button when it’s waiting on shutdown, but I’ve had less consistent success with that.

What surprises me is that they count using an email service as self-hosting. With that logic wouldn’t bluesky get a high score because people can bring their own domain easily?

Whaaaaaaaat? Pivot tables are a 2 second job to summarise large amounts of transaction data or similar by month or year. Lookups or countifs would take so much longer!

Not to mention that you can drill into the data using them.

You sound like you know your LibreOffice.

My experience is they are quite different but I’ve been able to do the same things for the most part.

But how the hell do I make a pivot table that looks and functions as nice as the plain old default one in Excel?

Or just browse All

Ah I guess it’s that it shows what they want then they have to install the app to buy it?

Maybe this article is intended for advertisers to convince them of the value.

Isn’t the idea that if you advertise you will get more people looking at/downloading your app and therefore rank higher?

It doesn’t make it not paid product placement, but I don’t think it implies that people are buying spots on the ranking.

It does imply the rank is almost useless because most high rankers are just spending a lot on ads.

Yeah, they do ship to Oz. But you can’t pay with an NZ card so you’ve gotta do a whole thing where you send money internationally to a friend then they pay and order and receive it then ship it to you. It seems like a big ask for contacting a distant relative out of the blue and asking them to do that.

Same here! I have one but can’t get components any more because they locked down freight forwarding 🙁

That’s a little bit different.

In your case, the wind is blowing and the craft is getting energy from it.

I was referring to the energy coming from the motor pushing you through the air and then trying to claim some energy from the wind you created by pushing yourself through the air with the motor.

If there is wind blowing you could in theory get some energy from it, but the thing about sailboats is there is a constant need to adjust the sail when you turn. A turbine on the front isn’t going to be angled correctly whichever direction you turn.

But I think I worked out the reason for the turbine. It’s powered by the battery (it’s not intended to charge the battery) and I think is there to pull the top of the contraption forward so it doesn’t fall over when accelerating.

I think I’ve worked it out, after some discussion in another comment thread.

This contraption probably has a high centre of gravity and would tip over backwards if you accelerate too fast. They probably worked out a wind turbine on the top spreads the acceleration force and reduces this problem. The turbine is not for generating power, it has a motor and is used to give some thrust to the top.

I think I’ve worked it out. I think it’s not generating power from wind, it’s additional thrust. It seems pointless since they could have put a bigger motor in?

The article in the OP links this source, but it only has an info sheet. It’s in Chinese but it’s just a list of specs. But there is one small hint. The top table has (assuming machine-translation is correct):

Wind-Powered Range ≥50km

The bottom table has:

Wind Power Motor 300W/72V (Permanent Magnet Brushless)

So I’m convinced the intention here is that the motor spins the wind turbine to pull the bike forward.

It doesn’t seem to make sense from a thrust point of view, so I have a new theory - this contraption probably has a high centre of gravity and would tip over backwards if you accelerate too fast. They probably worked out a wind turbine on the top spreads the acceleration force and reduces this problem.

But it doesn’t help. If you are travelling forward under the force of the motor using the electricity, then using the wind from that forward motion to generate electricity with the turbine will produce less electricity than the extra energy needed to propel you forward when you have a turbine on the top creating air resistance. If you could use a motor to travel forward and use a wind turbine to capture energy from that motion in a way that produces more power than you put in, well that would be a source of infinite energy. It violates the law of conservation of energy.

The only thing I can think of is that it generates electricity from the wind when you are not moving. But considering the size of it, I can’t imagine it’s worth it to generate that tiny amount of electricity when stopped to then have that increased drag when moving causing you to use more power.
