Luc··on Southwest Headquarters Tour
There appears to be a rope-like device on the emergency equipment training board (8th picture), with some bicone shapes.

Anyone know what that is?

Perhaps an escape rope for the pilots?

EDIT: Yup, here it is in action: https://www.jetphotos.com/photo/7389569

It's probably 'displacement'. This worked together with ORG ('origin'). ORG specifies where in memory the code will run. DSP then moves the code the specified amount further along in memory, with the understanding that it will be moved back to the ORG address when it needs to run.

Same as DFM, but generates PETSCII instead of ASCII.

Luc··on South Korea police arrest man for posting AI photo of runaway wolf
Small and low energy enough that tiny migratory birds can wear them for months. Externally worn of course (e.g. attached to the ear, for a wolf).

You could adjust the firmware of a wildlife tag to start transmitting location every 10 minutes when the animal leaves a geo-fence.

Luc··on U+237C ⍼ Is Azimuth
Thanks for the clarification. I did see some things in your comments (for example giving references in the one above) that made me suspect this.

I dislike the character imparted to your words by the LLM, though. Knowing that it is artificial makes me feel it's more of a waste of time to read it. But I will try to ignore it.

This account is an LLM IMHO.

Sextants were used for coastal mapping though, albeit specialized ones called hydrographic sextants.

You can see one here: https://sextantbook.com/2019/01/13/a-french-hydrographic-sex...

The linked article is by W.J. Morris, and his book on sextants is in my opinion one of the standard works and much recommended.

Luc··on US economy unexpectedly sheds 92k jobs in February
72% is just not a believable figure. I assume we're talking about TUI here, and they haven't announced anything about this 72% as far as I can tell.

That can't be right, the real figure is probably closer to 7%.

> However, you can save 1 byte of RAM by using the branch instructions instead, as long as you know which flag(s), if any, are guaranteed to be on or off at the jump point.

> For example, if you know the carry flag will always be clear at the jump point, and if the jump distance is within branching range, you can replace JMP with BCC.

However if the BCC crosses a page boundary it'll take 4 cycles, one cycle longer than a JMP.

Luc··on Lost Soviet Moon Lander May Have Been Found
The Soviets tried to transition from an economy focused on war and heavy industry to a consumer oriented economy, and they failed massively. See the book 'Building a ruin'.

A substantial percentage of the population (10% to 15%) has IBS-like symptoms, and would be sensitive to even small amounts of polyols (another name for sugar alcohols).

Hence why they are excluded in a low-FODMAP diet (the P stands for polyols).

I noticed the lack of glue and yellowed tape. Actually it consists of strips of paper that are 12 foot long, taped together.

Any navigator worth their salt would take rather take more than fewer chronometers, for various and frankly obvious reasons.

Luc··on Erich von Däniken has died
No need for pi.

If you know the angle and the distance between the two cities, you can just multiply the distance by [full circle divided by the angle], and that's the circumference.

It's the other way around. Think about it, how would the oil travel to the rest of the tool that's not touching the felt?

Felt is bad, it wicks away oil from the tool's surface and often absorbs moisture from the air. Tools placed on clean felt will often rust where they touch the felt.

You need to mitigate its wicking and hygroscopic properties by applying lots of oil to it. Use rubber mats instead.
