Definitely wouldn't be unheard of in the Fintech industry. But I don't know, because I don't use the service. My bank thankfully offers their own implementation of NFC payments within their own app, so I don't need to rely on any third-party services. Many banks in Europe actually do this. Here's a German article about Google-free mobile payments on GrapheneOS: https://www.kuketz-blog.de/nfc-datenschutzfreundlich-bezahle...
> Plastic production has climbed from 2 million tonnes in 1950 to 475 million tonnes by 2022, roughly equivalent to the weight of 250 million cars.
That's 60 kg/person/year of plastic, which is a lot. Or about 4800 kg for a person living 70 years. Obviously, there is wide variation in this number across the human population.
Mathematica's notebooks are the only environment where I can do some computation to arrive at a symbolic expression. Copy the expression from the output cell into a new input cell. Then manipulate it by hand into the form I want. Then continue processing it further.
Also, symbolic expressions can be written nicely with actual superscripts and subscripts, and with non-latin characters.
(AFAIK, you can run Mathematica sessions in TeXmacs, get proper typesetting, and can copy/paste expressions for simplification by hand or using other CAS sessions in the same TeXmacs document).
If you create an open club for your hobby in real life, you will also get weirdos joining your group. These people will commit minor offenses like disturb others and serious offenses like sexually harass someone. A club that includes teens will, with non-zero probability, share porn with each other, or even "inappropriate" pictures/videos of their peers - the latter of which is a very serious crime.
You can avoid this in both real life and or the internet by making very closed clubs in which only very trusted people are added.
> I must admit that when I send a really important email, I check the mail server log if it went off without errors, but this does not bother me as checking logs manually once in a while is a good thing anyway.
I also self-host my email. It would be very nice if there was some sort of notification system that alerted you if your email got bounced by the receiving server. A notification that fed through into Thunderbird would be marvelous.
Well I don't know if you wrote this in a sarcastic way or not, but when you write a new message in Thunderbird just turn on `Options -> Delivery Status Notification` and your mail server will email you back with a delivery status message (success or failure, although failure can take some days if the receiving server doesn't outright reject your message)
I was not sarcastic. I just tried this by sending from my gmail account to one of my other accounts. Didn't get any email back even though the email was immediately delivered.
ah sorry, I thought you wanted a delivery notification when you are sending an email via your own SMTP server (i.e. when thunderbird is configured to use your own outbound SMTP gateway)
An A320 can store 24k liters of fuel. Jet fuel stores 35 MJ/L. So, the plane carries 8.4E11 J of energy. If that was stored in a battery that had to be charged in an hour 0.23GW of electric power would be required.
So indeed, an airport serving dozens or hundreds of electric aircrafts a day will need obscene amounts of electric energy.
Electric motors can be pretty close, 98% is realistic. Of course other parts of the system will lose energy, like conversion losses.
Of course that doesn't mean batteries are currently a viable replacement. One should still take efficiency into account in quick back of the envelope calculations.
It makes no difference, we’d still need gigawatt scale electricity production, with some multiple of that at peak, just for a fairly unremarkable airport.
What about movie rentals on various platforms like Youtube. They are more in the domain of "milli"-payments, but they do share the feature that you don't know if you will like the movie until after you have watched part of it.
With a movie rental I'm paying $5-30 for a 1-2 hour experience where I have some idea going in of what I'm getting thanks to trailers and I'm making that decision maybe once a fortnight if that.
- RBC 2FA is that if I try to login through my browser, the phone app will ask if I authorize the login. I think I can disable this and use sms/call, but that's even more insecure, so I don't.
- TD lets me login fine and do everything in the browser. But any online transaction that is moderately large or presumably fishy, will force me to authorize the transaction via the app.
I've never seen a website break because of ublock, at least not in the default config. If it's that much of a problem you can just remote in on grandmas computer and disable it for whatever website.
I think that beats remoting in when granny inevitably gets scammed by an ad.
There really is no excuse in my mind for not running an ad blocker. It's as vital to personal computing security as firewalls and anti malware.
Blocking ads helps grandma not accidentally leak private information that could have disastrous consequences, for example, getting scammed out of their money.
Not blocking ads helps grandma visit a few more websites that don't work well with adblock.
The Canadian government has been trying for about 4-5 years now to get Canadian banks to embrace Open Banking, which will allow these sorts of products to be built quickly.
The banks have consistently refused to do anything, because they don't want any change that threatens their oligopoly. Canadian bank services are more or less the same as they were a decade ago.
The current government will have to show that it can resist rich people lobbying in this regard, before any real change can happen.
Indeed, no one seems to ever talk about the banking monopoly in Canada so it's not a big political issue. It's not nearly as controversial as the telecom or airline monopolies.
There are some new banking startups popping up in Canada like Neo Financial (from the guys who made SkipTheDishes) but they are online-only and have limited integration with stuff like Plaid.
Canadian banks still live in 2006. They can't even make EMT transfers more convenient, so people could request a payment or pay with QR.
Sometimes I feel like they don't actually refuse to do things, maybe they are not capable to improve. Something in their chain of command is broken and doesn't let them change.
