perilunar··on The largest electric aircraft just flew [video]
> I will never fly on any aircraft that does not have a minimum two-person crew on the flight deck.

You're missing out. Flying solo in a small plane is great.

perilunar··on Qantas Airbus A380 engine failure in 2010 (2023)
Though in this case the software mitigation was turbine overspeed detection, not overtemperature detection.
perilunar··on The Silo · interactive 3D cutaway
"We do not know why we are here. We do not know who built the Silo. We do not know why everything outside the Silo is as it is. We do not know when it will be safe to go outside. We only know that day is not this day."
perilunar··on Show HN: OwnTime – a chess clock for your day's priorities
Really nice looking app. I like the ambiguity of the name.

Was initially confused as to what the total of the ring was — took me a moment to realise it's 100% of the time allocated, not the whole day or the workday. I'd probably want to always allocate 24 hours of tasks (including sleep and downtime) just to get a 24 hour ring.

perilunar··on Native Apps Why?
I think the divide is pretty clear.

If the app needs connectivity for data, and is just text/images/video, then yes, it should be a web app. e.g. news sites, social media, forums, etc. (It's a site, not an app).

If an app needs be able to work offline, on local files and data, then it should be native. e.g. office apps, image/video editors, maps, CAD, etc.

There's a grey area in between, but usually it's pretty obvious.

perilunar··on Glacier Mice
> "The use of accelerometers has demonstrated that glacier mice do in fact rotate and roll, rather than simply sliding across the ice

You would think a timelapse video would also demonstrate that, and be much simpler to set up.

perilunar··on China is fueling America's data center rage
It will be ironic if China-fuelled opposition to data centres in the US is what makes orbital data-centres economically viable. A bit of an own-goal.
perilunar··on A society that runs on stimulants is badly broken
no, opium.
perilunar··on Sun Clock
The green hand is the minutes hand.
perilunar··on Activation Energy is a good model for a lot of things
> There are really important non-linear situations

I would even say that most things in life (including life itself) are non-linear. Exponential growth and decay, homeostasis, sigmoid curves, hysteresis, quadratic and other higher order curves, sine and other waves, Gaussians, etc. Linear relationships are more the exception than the norm.

perilunar··on Why Don't We Version UIs?
They can't leave it alone. People at organisations change, and new people always want to put their own stamp on things. "Made some incremental improvements" doesn't look good on the resumé.
perilunar··on We've flown a radiation-blocking vest to the Moon and back, and it worked
Cheaper mass to orbit is undoubtably good, but not all mass, shielding or otherwise, needs to be lifted from Earth.
perilunar··on Sun Clock
You can: there's an option in the settings panel (the gear icon on the top right)
perilunar··on Sun Clock
I wonder if that's a common thing generally or not. Definitely I should add it as an option though. Also whether the year starts at the top or bottom of the dial.

The planets do go around the Sun anticlockwise when viewed looking down from above the North pole [0], and most diagrams show it that way, so maybe that's where the idea comes from?

hi :)
perilunar··on Sun Clock
Author of Sun Clock here — thanks for the library! I'll check out the new release soon and update.
perilunar··on Sun Clock
Same here, but i'm in the southern hemisphere, so summer is at the top already.
perilunar··on Sun Clock
Author here — I'm thinking of adding something like that to the calendar page, or adding a separate 'carpet plot' of times over the year.

> how to handle the corner cases where the sun rises but does not set (and vice versa)

In practice it doesn't matter: you get a thin sliver of twilight between solar midnight and sunrise or sunset, and a 'Sunset: Does not occur' message in the text info. In such cases the sunrise/sunset arc (sector?) is pretty broad anyway.

> or if it should be tomorrow once you’ve already passed that time

Yes. I chose to recalculate the times midnight.

> Either way, at a certain point you’ll see the UI shift

Yes, but it's usually not dramatic. A few minutes time and fractions of a degree each day. The biggest shift occurs when Daylight Saving time changes — you get a big 15° rotation in the display. Most people are asleep when that happens, but it's cool to watch it jump.

> what are the actual ways to not live under the rule of an industrial clock?

Become a farmer. Live by the Sun and the weather instead of the factory or office clock.

perilunar··on US Air Force jet engine manufacturing plagued by 'significant challenges'
The US is not about to be attacked. But your allies are getting sick of your bullying and hypocrisy. Without allies you won't keep your overseas bases, and without those you cease to be able to project power and maintain global dominance.
perilunar··on Show HN: Programmable timer web app (for gym workouts or stretching sessions)
If you 'Add to Home Screen' you don't get the address bar. Effectively fullscreen.

Not sure how that would work with the state being saved in the URL — you'd need to save each routine separately I think.

perilunar··on Elevators
It's a pity that paternoster lifts are so unsafe [0] — we could avoid all problems to do with scheduling if they were safer.

On a related note, could someone please design continuous spiral escalators with horizontal sections at each floor?

Just imagine what you could build with 600 Falcon 9 upper stages.

Nothing stopping you — it's still there and still works. I use it for one of my sites.

As mentioned above, adding a viewport meta tag will make most unstyled pages look much better on mobile.

<meta name="viewport" content="width=device-width, initial-scale=1.0">

> Why are mobile browsers defaults so wrong?

History. When mobile browsers first appeared they had to default to a desktop page width to avoid breaking exisiting content, much of which was either built in layout tables or used CSS that assumed a wider window. The viewport meta tag was introduced (by Apple in Mobile Safari when the iPhone first came out, IIRC) so developers could override that behaviour. I think the defaults made a lot of sense at the time, and Apple made the right choice.

perilunar··on Ask HN: Is there a "mouse" for parallel work?
Are you asking, or are you trying to drum up interest in a product?
