Is this just an ad for Delta? I couldn't find the answer to "Why Delta Air Lines Doesn't Want Blended Winglets on Most Aircraft Anymore" (just that they seem to have switched to the split-scimitar, not why) but I could find out a tonne of details about their "new first class seats, which debuted in 2022..."

You open with

> Every driver in the UK has experienced this. Most assume the truck driver is being inconsiderate.

But then go on to explain how that is exactly true. The truck driver is taking time from *all* drivers on "roughly 4.5 miles of dual carriageway", just so that they can end the day 5 miles ahead.

> The five minutes of inconvenience to you saves them meaningful time and money over the course of a day.

It's five minutes of inconvenience to *everyone* on that 4.5 mile stretch of highway that nets the truck 5 minutes (5 miles ahead at ~60 mph). That's a very selfish and inconsiderate outcome.

Have you tried renting recently?

New CEO will be Asha Sharma, who was the president of CoreAI at Microsoft.

It’s a little worrying that she has to include this preemptively in her statement:

"We will not chase short-term efficiency or flood our ecosystem with soulless AI slop."

> Autopilots in airplanes are kind of dumb (keep heading, speed, and altitude, they won’t do much anything else)

That is absolutely false.

A 20 year old avionics suite in General Aviation (GTN 450) does much more than maintain altitude, speed & heading - you input a flight plan including an approach, it will fly the flight plan, capture the approach signals (VOR/localiser/whatever - which is far more complex than “keeping course”) all the way down to approach minimums.

It can go down to 200ft for an LPV approach.

The trend is to include as much as the aircraft’s capabilities in the checkride now.

For an IFR checkride, if you do it in an aircraft equipped with autopilot, at least one approach will have to be flown with the autopilot.

Not sure if that’s made it’s way to the PPL checkride (or been codified) but it’s inevitable.

Not that I would necessarily trust a verification badge for someone who controls the company with the responsibility for generating verification badges.

There's a big difference between utility classes which are shorthand for inline styles (random example from Tailwind's site where every single class is a one-to-one mapping with a single style override.):

    class="ml-3 hidden rounded-lg bg-gray-100 px-2 py-0.5 text-xs/6 font-semibold whitespace-nowrap text-gray-700 lg:block dark:bg-gray-400/15 dark:text-gray-300"

and semantic names which use the CSS cascade:

    class="main-content subheading"

Calling that a shorthand for inline styles is just being obtuse.

Isn’t that what utility classes are? Shorthand for inline styles?

Not saying it’s good/bad, but it feels like that’s the use case

Also used incorrectly most of the time. They meant to use “debatably”.

Arguably:

- used to say that a statement is very possibly true even if it is not certain (merriam-webster)

- in a way that can be shown to be true (cambridge)

ie. you can be prove it through argument, not “you can make the argument”

You are confident that I am wrong - why don't you share your source?

I'm giving ballpark numbers because I am in this space and don't want to dox myself.

Then you should be asking them instead of arguing with random internet people

No, I know how much each honeycomb costs (BOM cost, that is); pretty confident on the radars; and I can guess at the cameras and compute.

$50k? The sensor kit on the Waymo’s ipace is north of $300k. (Which completely inverts that calculation)

Right, but you do stuff other than work 24 hours a day, right? You have fun, relax, etc.

Counting the 100w for 24 hours for a human doesn’t match up with counting the power usage from “AI” for only the 10 minutes it’s doing a task.

Also - units issue: 100 watts for a day is 2400 watt-hours. It’s a moot point anyway because the power draw for the frontier models is an order of magnitude off that the division by 24 is basically meaningless.

If you as a human are coding for 24 hours a day as the benchmark for LLM efficiency we have other problems.

A human consumes about 100 watts when not doing any physical exertion (round number, rule of thumb). So unless you can show an LLM running on 100w compute with capabilities similar to a human, they’re less efficient.

The CVE referenced is caused by this commit:

One of the changes is:

    -  getterminaltype (char *user_name, size_t len)
    +  getterminaltype (char *uname, size_t len)

What is the reason for a rename these days? If I saw that in a code review I’d immediately get annoyed (and probably pay more attention)

Betteridge's law done right! Answer then explanation

I think Publisher would be the equivalent to FrameMaker from the Office suite. Publisher from Office ~2016 could definitely do that.

Unfortunately I think Publisher has faired even worse than Word in terms of stagnation, and now looks to be discontinued?

I’m confused, the statement is that SQLite has a proprietary test suite? It does. Where’s the FUD?

Turso tried to add features to SQLite in libsqlite but there were bugs/divergent behaviour that they couldn’t reconcile without the full test suite.

The next bullet point:

> 2. The TH3 test harness is a set of proprietary tests…

> then it pushes a validation request to my phone and with FaceID I'm in.

That’s exactly what I don’t want though. I don’t want to be tied to a bank app that requires a non-rooted device/whatever other checks it does.

Chase allows both SMS and their app to be the 2nd factor; I dislike both of those options and would much rather TOTP

Which banks do you use? I’m looking to switch away from Chase (which does this).

It’s a surprisingly hard thing to search for online…

> But it did look like an F-14

It absolutely did not. The RCS of an F-14 v/s an Airbus A300 is an order of magnitude different (probably 2 or 3 orders).

> There really was an F-14, just on the ground at an Iranian airbase

There was, but that’s a red herring for the root cause. Each ship’s radar independently and correctly identified and tracked the Airbus separate from the Mode 2 targets, but when communicating the track information between ships, the tracks were mixed up.

Mercedes Drive Pilot (“SAE Level 3”) is certified on some very specific stretches of insterstate in California to not require the driver to be responsible.

Requirements:

- Stop and go traffic (or less than 40mph?)

- On some specific sections of highway

- Driver doesn’t need to monitor but must be ready to take over with 15(?) seconds of the system requesting

> Mercedes-Benz is assuming liability for any crashes or incidents that occur while the autonomous system is active

> When I was testing vehicles in 2019 I found that a bunch of them had lane keeping but they kind of "bounced" between the lines

That’s lane keep/lane assist; not lane centering. It’s supposed to bounce between the edges of the lane. (I guess, not supposed to, but that’s what it does as opposed to actually tracking some position in the lane).

The auto industry as a whole did a massive disservice not clearly differentiating “lane keep”/“lane assist” v/s “lane centering”. They are hugely different and trying to use lane keep to stay centered is really dangerous.

Same model car with different trim levels/packages would have lane keep or lane centering making it really confusing to consumers what they had and what safe usage would be.

> It's... a car. You already pay a monthly fee

Eh? Insurance? Registration? Not a fee but ok, ongoing cost. That doesn’t justify more ongoing costs.

> FSD is in fact market leading.

The article and the discussion is about autopilot, not FSD.
