Loved the thought processes in this post, so definitely interested. Notion always feels half-baked.

On the huge pile of money he made shorting the pound before the vote.

Why would an outdated OS prevent emergency calls specifically?

Some handsets do not connect to secondary networks for emergency calls without the update that fixes the problem.

https://www.abc.net.au/news/2025-10-22/samsung-mobile-device...


This is explained if you click through the link to the Samsung post about this issue.

> Australian mobile operators and Samsung have identified a number of older mobile devices that will not correctly connect to an alternative mobile network to make Triple Zero calls when the customer’s primary mobile network is unavailable. These devices need to be updated or replaced to make sure they work reliably in an emergency.


If the OS doesn't recognise it as an emergency number then it may fail the call if it believes that whatever network it is associated with won't connect it ("No service" vs "Emergency calls only" indicators etc if you are out of coverage from your SIM's network but within range of other networks).

Emergency calling is supposed to work over any network (even without a SIM card inserted, much less an activated, registered, associated one), but only if the OS tries to dial it as an emergency call.


But this wasn't a new emergency number.

It's not about the "age" of the number at all, devices are mandated to try all available networks when it is a recognized emergency number. In this case, even though the number was indeed a device-recognized emergency number, it failed to try all available networks as mandated. The article mentions Triple Zero several times, but not because that is specifically noteworthy beyond it being the typical emergency number.

For example if your phone only makes emergency calls over 3G and the carrier shuts down 3G, then you will be unable to make emergency calls anymore.

What happens if I don’t act?

Under the Government’s Emergency Service Call Determination, all mobile network operators are required to block devices from their networks that are not configured to access emergency call services. If your device is on the list of impacted devices, you will have 28 days from when we notify you to update the software or replace your device to stay connected to the Telstra network. After this time, the device will be blocked from accessing all Australian mobile networks.

Can I still use my phone on my home Wi-Fi after it is blocked?

Yes. Your phone can connect to a Wi-Fi network for data purposes only. However, blocked devices won’t be able to make or receive voice calls over Wi-Fi, including emergency calls, or send and receive SMS.

Emergency calls often aren't just normal phone calls. At least in the US, they're required to transmit their location to the operator, and this is the case in many other countries as well. I doubt the technologies are standardized.

It would be surprising if location transmission failure led to complete call failure. You'd think that it ought to fall back to just making a regular phone call.

I remember an old Android crashed or something. Maybe it still carried that bug?

> Google Vertex is their equivalent of Amazon Bedrock

Well, that clears that up.


In "real world" you don't use OpenAI or Anthropic API directly—you are forced to use AWS, GCP, or Azure. Each of these has its own service for running LLMs, which is conceptually the same as using OpenAI or Anthropic API directly, but with much worse DX. For AWS it's called Bedrock, for GCP—Vertex, and for Azure it's AI Foundry I believe. They also may offer complementary features like prompt management, evals, etc, but from what I've seen so far it's all crap.

Came back up for a few minutes and has gone down again. https://www.cloudflarestatus.com has nothing.

Imagine how much of that traffic was just the bots following the endless redirects.

Those redirects would crash Azure, i'm betting a grand

Maybe buy your bulbs somewhere else? I'm yet to replace any of the LED bulbs I've bought over the past 15 years and honestly can't even remember the last time a bulb failed.

Actually, since posting this I've vaguely remembered a previous discussion on here about differences between LED bulbs sold in the US and those sold in UK/EU so maybe that explains it.

Mine fail all the time. Cheap Amazon Basics, expensive Phillips.

Do they fail more than incandescents? idk maybe not, but they fail much more often than their advertising would suggest.


It's just pair programming when you're doing it on code so if you can bear pair programming you'll be fine. Personally, I hate it.

Pair programming usually has a single "driver" on the keyboard to keep things controllable. Here, everybody is driving: "dozens of cursors are concurrently editing the same file in real-time."

That's not how they, or anyone else, uses it on code though - that's on their notes. This is just a feature, it's up to you how you use it.

The concept of sharing and taking turns has been lost on the software engineer here....

a few years ago our company used Screenhero which allowed editing with multiple cursors while screensharing.

The experience was actually quite nice for two-three people but we always had the "ok let me type now" flow. Multiple changes happening at once sounds hyper distracting.


my understanding is that this is the dynamic in modern college classrooms. everyone opens a big shared google doc for notes and they all collaboratively edit a set of notes in real-time.

or at least that's what i've heard, no idea if they actually do it.

it is nice to see a crdt backed editor tool for markdown and code though. gdocs markdown support has been lacking for years.


> or at least that's what i've heard, no idea if they actually do it.

Yeah, we used to do that back when I was in college. It's only for certain classes and most people usually kept their own notes too (or instead, why write twice). Or some classes ban laptops so you'd write on paper anyway.


True, but the option of wysiwyg for editing markdown would really be a great addition. Or even just for preview ... https://github.com/zed-industries/zed/issues/21717

The metaphorical infinite monkeys on typewriters.

Actively programming in pairs (or more) is also not for me. Reviewing work async is great IMO though.

Yeah, people are different, but a lot of this difference results from various constraints, such as cultural practices around collaboration or technological options. Many of these limitations probably shouldn't be locked in by our tools or norms.

When learning a new way of thinking or moving (i.e. martial arts) people often really benefit from high-bandwidth, low-latency, shared-viewport-onto-reality interactions. Watching someone's cursor move while they talk is one way to get a window into their problem-solving toolkit.


Oh no. I look forward to watching my browser redirect 40 times on every attempted page load.

(Nearly?) all of the the "private" rail operators in the UK are actually the national operators of other countries - Germany, France, Italy and I think Netherlands. The national rail operators mostly know how to run a decent service, but in the UK passengers pay multiples of what those operators charge in their home country and the service is definitely not as good.

You are aware National Express (UK company) operates a lot of train routes in NRW in Germany, too? Equally Ariva (UK company, was owned by DB, now UK) in the Netherlands?

The EU basically mandates privatisation of railways.

They require track and trains to be run by different operators (DB InfraGO in Germany, ProRail in NL, etc) to the train operators.

They then require (nearly?) all passenger rail operations be available to private companies to bid on. The EU is taking the Netherlands to the ECJ over the fact the Netherlands won't allow it: https://ec.europa.eu/commission/presscorner/detail/en/ip_25_...

Also the EU requires open access operators access to said separate tracks. That's why you're seeing all the competition in high speed routes (especially) in the EU. They have to pay a track access fee but are free to request to run whatever route it is.

The last point (well, all are really) is a big problem for many national operators as they make a lot of revenue from 'premium' intercity operations that cross subsidies the local trains. A lot of that "margin" is going to be eroded by the competition.


Technically Arriva is now American owned.
