Jokes: I have one in my pocket right now!
wpearse··on A 10-Year Battery for AirTag
We put AirTags in road cases/Pelican flight cases packed with AV/IT equipment. Pelican makes a stick-on AirTag holder that works well.

We’ve found the AirTags work just as well as LTE/4G GPS trackers —- with no-ongoing costs, better battery life (we get 6-9 months on the AirTags, 4-6 weeks on the GPS trackers), and AirTags are 1/5 the cost of an LTE tracker.

This product would work well for us.

wpearse··on Starlink's first constellation of direct-to-phone satellites is now in orbit
I'd love to see my Tesla use Starlink LTE.

Whatever local provider my Tesla connects to doesn't have great reception. The onboard streaming music often cuts in and out.

wpearse··on Cruise ships chopped in half are a license to print money
My colleagues and I put the work line on an eSIM so we can turn the work “phone” off completely with a toggle in the Settings app.

(If anyone from Apple is reading this, would be great to be able to schedule DND on a eSIM line.)

wpearse··on 32by32 – Macintosh History from the 1980s
Weirdly -- I seem to remember seeing a lot of ,€“ on my old Macintosh ~25 years ago. I think this could be intentional reminder of the "old days", and not a mistake.
wpearse··on NZ’s biggest data breach shows retention is the sleeping giant of data security
Understatement is a hallmark of the Kiwi culture. “This is not OK” is also a very stern telling off from your mum or school teacher.
wpearse··on Show HN: Pole Clock, a single 24h clock with multiple timezones
I used to work with a delivery route planning system that had 24:00 as midnight on one day, and 00:00 was midnight on the following day — the same “instant” but on two different days.

I forget the reasoning, but I remember it being described to me as both necessary and a reasonably common construct.

wpearse··on Warming up your car before driving in cold weather can damage the engine (2016)
Smoother surfaces, less friction, less wear, increased longevity.
wpearse··on Tesla Vision Update: Replacing Ultrasonic Sensors with Tesla Vision
I drive a 2018 Hyundai IONIQ EV. The forward radar is hit-and-miss in heavy rain: the car will often barrel quite happily into stopped traffic when it’s raining hard, requiring a stomp on the brake pedal.

Just a couple weeks ago I was driving on the motorway around 4am, no other traffic for miles, and the forward collision alert sounded and the car slammed on the brakes for ~quarter of a second and then released as if nothing had happened and we merrily resumed our journey. Having the brakes slam on at a smidge over 100 km/h gave me a sore shoulder and quite the rush of adrenaline, quite the rush at 4am!

So yes. The radar does have a mind of its own.

wpearse··on Emergency SOS via satellite is included for free with iPhone 14 Pro for 2 years
Friend of a friend works the satellite trucks for onsite broadcasting at sports events. He told me once that he phones the satellite operators and they coordinate to make sure the beams are aligned as tightly as possible to reduce the power loading on the satellite. I’m guessing there’s probably a similar constraint here — I don’t think (pure conjecture) it’s feasible to have a tonne of iPhones (and let’s be honest, they’re everywhere) hanging off satellites.
wpearse··on Tempest LCD: Playing songs from your LCD monitor with a radio
It’s true! They’re teaching kids at the local school how to build AI to help assist with their grammar and arithmetic!
wpearse··on Objective-S: architecture-oriented language based on Smalltalk and Objective-C
I can’t speak for other ObjC devs back when the iPhone SDK was released; but I remember just being so grateful that I had any tooling to develop for iOS that I was more than happy to overlook any ObjC weirdness/clunkiness.

ObjC is very simple (often confused with archaic), but also wildly complex. Once you wrap your head around the ObjC way of doing things, everything makes sense, is very consistent, and you could develop very effectively.

wpearse··on Objective-S: architecture-oriented language based on Smalltalk and Objective-C
It’s been almost a decade since I did any ObjC, but I’m fairly certain that you want to use NSMutableString here :p

And, don’t forget to release your alloc’d objects (or use an auto release memory pool). There was no automatic memory management then!

wpearse··on I still love PHP and JavaScript
I did a 100-level paper at University that explained floating point arithmetic and how to solve for equality. Without being snarky, how do developers miss this sort of stuff?
wpearse··on Ford's answer to EV supply chain hell: Cheaper batteries
My EV is 1/10th of the cost to run and maintain than my diesel car. I’m more than happy to spend an extra 20-30 min charging on a 4 hour drive when I choose to drive the EV.

My diesel has also done just over 340,000km and it’s pretty shot. Hard to start on cold mornings and I’ve had to sort out some leaky injectors and seized joints on the driveshaft. There’s another couple of hundred thousand kilometres left at best.

The EV is coming up to 100,000km and it stills drives just as spritely as the day I got it. The battery is showing 100% state of health and I’m convinced it’ll happily do a million kilometres or more.

wpearse··on Toyota’s Chief Says Electric Vehicles Are Overhyped (2020)
Hey, I felt exactly the same way about ICE vs EV. I have a V8 that I tinker with on weekends. I have 4 other ICE vehicles.

The kicker for me was borrowing a friend’s EV for the day. The driving experience was so completely different to my cars it was mind-boggling. The only other time I’ve felt the same way was picking up the first iPhone.

We bought an EV a couple years after that (6 months ago, now) the first couple of weeks we struggled with range anxiety and suffered from inconvenience. Now we’re completely in love and wouldn’t ever buy another ICE. (Except maybe another old Saab…)

wpearse··on Toyota’s Chief Says Electric Vehicles Are Overhyped (2020)
We bought an EV 6 months ago. We financed ~60% the purchase cost over 3 years. We would otherwise never have spent this much on a car.

We calculated our estimated petrol savings and put down a deposit large enough such that our weekly finance payment and estimated charging cost combined would be ~75% of what we’re spending each week on petrol.

Now that petrol prices have skyrocketed, the finance cost of the car + charging cost is less than half of what we were spending in petrol.

So far we’re very happy. Our total running costs for our petrol car was around 28c per km, our total running costs for our EV are around 4c per km. (Total running costs = absolutely everything attributable to the vehicle: fuel/charging, servicing, insurance, tyres, wiper blades, …)

wpearse··on Everything with a battery should have an off switch
We switched to buying USB-rechargeable AA/AAA lithium ion batteries. The brand we buy is Pale Blue, but there are many other brands.

These batteries have a regular form factor, with an added micro USB (and USB C on some larger battery sizes) port for recharging. They work really well for us and charge quickly (and conveniently — everything has a USB socket nowadays).

The price may seem expensive, but after 10 or so charge cycles they should have paid for themselves. I expect these batteries will be good for many hundreds of charge cycles.

wpearse··on Apple Discontinues macOS Server
Take a look at Mosyle, free for up to 30 devices? I think it’s where we’re headed when we leave Profile Manager.
wpearse··on Mac Studio M1 Ultra Teardown [video]
I took apart a 2010 Mac mini the other to install an SSD. It’s basically been running non-stop since new in a corner of our office for over a decade. Sure, there was some dust but it wasn’t at the point where it would affect performance. A quick wipe with a soft paint brush and it was as good as new — the first time we had ever opened this machine.

I don’t understand the insistence that we must regularly clean our computers, it seems daft. Maybe vacuum your house/office once in a while. The computer breathes the same air as you.

wpearse··on An update on AirTag and unwanted tracking
Can you? I was away with work for a week and left all my keys (with AirTags) at home. Got home and they were all in the fridge.
wpearse··on Green Bubbles: How Apple Quietly Gets iPhone Users to Hate Android Users
Is it _really_ an American thing? 11/15 of my top conversations are iMessage. Of the remaining 4, two are automated SMS (2fa, delivery notification) and the other two are Android users. I’m in New Zealand.
wpearse··on Boeing 777 departing Dubai nearly had a major incident after takeoff
The checklists bring the aircraft back to a known state.

One 777 pilot commented to say that this issue should have been caught by at least two checklists, implying that neither checklists had been followed.

Tangentially: if my 2006 Mercedes is reset (battery disconnected) it needs to idle for 20 minutes to re-learn the idle pattern. The vehicle then needs to be driven around for a bit to re-learn driving patterns. I wonder if there are similar settings on a 777 that would need to be preserved between 'resets'.

wpearse··on About the security content of macOS Monterey 12.1
My memory of Mac OS 7.1 was that it was rock solid. When it did bomb it wasn’t a surprise — you knew it was coming because you’d been messing around in ResEdit or playing with the debugger.
wpearse··on How to rest well
I’ll often have an espresso in the evening after dinner, and I sleep well after.
wpearse··on Apple Silicon Macs can't boot from external drive if internal drive failed
> it is now impossible to brick the system with a bad BIOS/EFI flash

I had to flash the T2 to do a Bug Sur update on my 2018 Mac Mini a couple weeks ago. The flash failed and bricked the machine.

Sent the machine in for service and the entire logic board was replaced under warranty, the machine was at least 2 years out of warranty as far as I know. This makes me think failed flashes are a known issue?

wpearse··on macOS Monterey
I just had a similar endless loop on update (Catalina to Big Sur) last week. Apple guided me to do a T2 firmware update which bricked the machine. Sent it in for service.

Logic board was replaced "under warranty" (it's a 3 year old machine with no Apple Care!).

wpearse··on After two hours zinc oxide sunscreen loses effectiveness, becomes toxic: study
Australasia has it particularly bad. I have fair skin — 20 min in the sun on a boat with no sunscreen a few summers ago and I had a series of doctors visits over the next week to treat the, quite literally, blistering sunburn.
