@casualstrader @xvrmdf Makes sense if you have to do a tax return, it might get taxed at source with no return needed.

[Daniel Chatfield @danielchatfield]

@casualstrader @xvrmdf Why would you want to opt out? Surely 78% of the interest is better than 0% of it?

[Daniel Chatfield @danielchatfield]

@zachtratar (It fails because it requires more permissions than our slack instance is going to allow e.g. DMS)

The issue is that if the org has setup org wide access we should be able to disable the user level prompt so it doesn’t cause confusion.

[Daniel Chatfield @danielchatfield]

@zachtratar we have an org connection between Notion AI and slack but individual users are still prompted to individually authenticate (which fails). Can this be fixed?

[Daniel Chatfield @danielchatfield]

New car keys should stop emitting the keyless entry signal after 10 minutes without movement.

Cars without this should default to disabling keyless entry between 11pm and 6am with an opt out in settings.

@GergelyOrosz What regulations?

@t_blom I’m in SF in a couple of weeks and really want to try a Waymo, do you still need an invite code?

@_josephwoodward Permanently runs at sufficient scale for 100% of payment processing. To direct all app traffic to it we need to scale it which typically takes a couple of minutes.

And yes, engineers are on call for it just like the primary system.

[Daniel Chatfield @danielchatfield]

I was part of a small team that built a completely independent backup Monzo that runs on a different cloud provider.

This ensures that even in extreme incidents we can still provide core payment processing.

@_josephwoodward This is naturally complemented by lots of unit tests, acceptance tests etc. – but the only way to be sure it will work when you need it is to actually exercise it regularly in production so that's what we do.

[Daniel Chatfield @danielchatfield]

@_josephwoodward 3) Multiple times a week we run an automated test where stand-in directly connects to payment schemes and actually processes payments for a short space of time and then disables itself.

@jonas Mortgage will be close to impossible and will make it hard to sell.

It is very hard to get rid of, every time you think you’ve done it, it will come back.

If it means you are getting a ridiculous deal and have no intent to sell anytime soon then might still be ok.

@lauriewired I think “stability” would be a better description than quality. There is a lot of decades old software that is very stable but objectively terrible quality.

[Daniel Chatfield @danielchatfield]

@mhudack I don’t disagree with that - but you still have to compare the magnitude of it. Is the avg cost of US health insurance a similar cost to UK tax burden from NHS? If not the “out of pocket cost” is a rather meaningless comparator.

[Daniel Chatfield @danielchatfield]

@mhudack From the comments on the linked thread I don’t think that’s accurate. It doesn’t include insurance premiums.
