jimktrains2on SQLite Critical CVEs or LLM Slop?

> accidental artifact of trying to make it give honest answers?

If it's not giving honest answers that implies it's purposely being deceitful, which it isn't capable of. Right?

jimktrains2on Is it time for a new Embedded Linux build system?

> I don't quite understand why "embedded" has historically meant learning a completely separate tool.

Because historically, and I would argue should still, refer to very limited hardware, in terms of memory, processing power, and energy.

jimktrains2on The TSA's New $45 Fee to Fly Without ID Is Illegal

But it's something they're choosing to do, not something that is required.

jimktrains2on The TSA's New $45 Fee to Fly Without ID Is Illegal

While I concur with your hesitation, my first reaction on hearing about the fee was "Didn't they say you couldn't fly without a realid? Why am I able to fly without one then?" The idea that they may not be able to bar you without one jives with how this is playing out. Another commenter in this post also mentioned flying without id, which I also thought wasn't possible.

jimktrains2on The TSA's New $45 Fee to Fly Without ID Is Illegal

I stand corrected, at least in Pennsylvania (1). I misremembering the issues surrounding requiring Id to vote. The law that was struck down did provide a free id that would have been suitable for voting; however, that isn't required and no longer exists, and there was no mention I could find of if it would have been realid compliant.(2)

~~~While it's not a passport, I believe most states have free id cards that are "realid" compliant.~~~

Edit: I'm wrong.

jimktrains2on What’s New in PostgreSQL 18 – a Developer’s Perspective

Since you can index expressions I wonder if that's because you essentially emhave to store the value in the index anyway and that wouldn't be expected for a virtual column?

I've used them for common transforms such as timezones (e g. data comes in as uutc and we query everything in Chicago time) just to make querying easier.

jimktrains2on Amtrak's New Acela Trains Are Here. They're Moving Slower Than the Old Ones

Just like on a car, if your break pads are capable of completely stopping the wheel, but the wheel is not capable of creating enough braking force with the surface, then you slide. If you lubricate between the wheels and surface, which is essentially what leaves do on rails, no amount of at-wheel breaking power will stop you.

This is what antilock Brakes in cars prevent, they pulse the brakes to allow the tire to regain traction, preventing slippage and loss of control.

jimktrains2on 2025 ARRL Field Day

As someone who only has a 5w transmitter, I avoid field day and major contests. I love doing Parks on the Air when camping, and that ends up being a lot more enjoyable.

jimktrains2on Cars and Key Fobs: Attacks on Car Remotes

> non-rigamarolish process of sharing a HomeKit home key

I have not used homekit, but from some searches it only seems to be a non-rigamarole process to add someone as a homekit user if the other person has an apple device? Also, is the Internet required to enroll someone?

> ones where the key holder is so incapacitated that they would be unable to share a physical key.

I don't need to be conscious or my phone have battery (or reception) to have someone take a key from my pocket.

> Also, every implementation of CarKit Car Keys I have seen is the same as HomeKit home keys: there is a backup. Either a physical key, PIN, fob, or card.

I was responding to gp who wanted none of this as it all defeats the security they desired. A 1-factor physical authentication token as a backup would be suitable for nearly all edge cases I can think of. As long as the person carries it, but then we are at worst where we are today, at best I could potentially authenticate or add someone from afar.

I'm not saying that smart locks aren't useful, just that they can't only be "smart", which I assume you would agree with since you brought up things currently having backup methods?

> By making adding an authenticated driver not a rigamarole, but easy and intuitive.

We'll have to agree to disagree. I don't believe that this will be possible in many situations. What if I'm not near my car? What if my phone is dead? What if my car's battery is dead and it needs jumped?

I'm also just cynical that the automakers or app developers are able to not enshittify the process.

What if when I set my wife up I added her as a user but not admin and now she can't share with someone without having to involve me, which may not be physically possible in all circumstances.

> They call you an ambulance.

You don't call an ambulance to take a drunk person home. Calling a taxi when there is someone able to drive is a waste of money and a huge inconvenience the next day to retrieve the car.

You also can't call an ambulance in the wilderness.

I also meant injured in a more broad sense. What if I just have a bad headache or migraine? I don't want to be fumbling with my phone or car electronics trying to navigate adding someone.

What if I'm not able to add them as an authenticated user or authentic myself to let them drive, e.g. I'm injured or very drunk?

Literally everything is pointless, even existence, from someone's point of view.

You don't have to understand how something amuses someone to understand that it amuses them. You also don't have to belittle people to ask them why they are amused.

jimktrains2on Ham Radio 101: What is WSPR?

Will such a system handle a sudden demand nearing the maximum capacity of its terrestrial counterpart? That's really the crux of the issue: in an emergency public networks can be overwhelmed.

Many county government agencies don't work with hams anymore because they have sat links and other communication available to them. I'm sure as technology progresses and it becomes feasible and affordable to give individual first responders satcom abilities, but I'm not sure that every person with a cell phone will be able to stabily access satcom in an emergency for a while yet.

I think they sound ok. Even when used as a Bluetooth headset for music there's enough bass that I haven't really thought about it.

I also have phonaks on a similar price range and mine sound pretty good. Could it be an issue with how they're configured?

jimktrains2on Is a 'slow' swimming pool impeding world records?

There's something to be said for racing _someone_ and not just the clock, for the swimmers/racers, not even thinking about the audience.

Additionally, it would make races take 8x to 10x amount of time.

jimktrains2on Saint Michael Sword: Are the cathedrals really on a straight line?

You could have two points in 2 of your non overlapping bands that are less than a band's width apart.

Also, the probability of the first 2 points will always be 100% because they define the line.

Also, it's not 7 random points, it's 7 of thousands of random points.

Without knowing the details, one difference from your hypothetical could be ease of access to 3rd parties, especially after death.

jimktrains2on Thanks FedEx, this is why we keep getting phished

That doesn't fix the issue though. The issue is a killer USB or a virus on the disk. Being able to only read an infected file still allows it to be read.

Also, this is only a software solution as the USB protocol would require bidirectional transmission.
