Thanks for linking Arcan, looks interesting.

After a quick scan, Arcan seems to be pushing a microkernel approach, with some clients providing display server capabilities and others talking to them via shared memory. This will have the same problem as all other microkernels - nice for research, but the extra completely outweights the marginal benefits over a monolithic thing that generally has a smaller API surface to maintain.

Wayland design choices are heavily influenced by automotive and TV where it has been industry standard way before it became mostly usable as a desktop. And that has lead to design compromises that look odd on desktop.

But hey, you can probably run automotive UIs with your desktop compositor.

And Gnome devs are just being silly at this point.

Contrails Map 7 months ago

I'm not following the logic why contrails cause net warming.

Why nuclear blasts - that also introduce lots of particles in atmosphere cause a cooling effect - "nuclear winter"?

QUIC for the kernel 12 months ago

The NAT firewalls do not like P2P UDP traffic. Majoritoy of the routers lack the smarts to passtrough QUIC correctly, they need to treat it the same as TCP essentially.

The minimum run time of a tread before it's potentially preempted when load is high is computed based on number of cores available giving more time when there are more cores since rescheduling latency is apparently longer with more cores.

And the function that does this uses the same value for 8 and more cores.

So the performance impact is likely <<1%.

Bicycles fail safe unless a wheel falls off or both brakes fail simultaneously.

Balancing onewheelers - if the control or power system fails, you immediately go down, hard. And since the cruising position is weight shifted forwards, it's 100% nose dive.

I suspect the part that is failing is not the connector itself, but rather a controller chip somewhere upstream.

Given the skills you could def DIY repair it for cheaper, the high price is likely including uncertainty of what's broken and some form of warranty.

For most use cases shortest path is super simple and fast problem on modern PCs. So might be useful on extra large synthetic networks. Neural nets?, Trading logs?, Image processing?

Also negative weights are rare in real life applications. And def not in what you would consider normal path planning.

Let me argue from the other end. The incident happened, which is obv not good.

What where the causes? How can we prevent this from happening again? What do other high profile perons do to prevent this from happening?

That sounds very wrong. Not a physicist, but light does not interact with magnets, or you need to get into the superconducting strength levels before it does.

It seems the optical rotation happens due to molecular structure of specific materials.

Edit, found this: https://en.wikipedia.org/wiki/Faraday_effect

So a specific material plus magnetic field is needed. But still not sure how strong of a field is sufficient.

DOS programs loaded fast, since there was around 1MB of working memory. Granted they did not do much, but where responsive, except when needed to do real compute, then you just waited forever.

Windows 3x/9x with first real multitasking and swap - things got quite sluggish. Early browsers were particularly eager of gulping ram and bringing everything to halt.

Nowdays it feels somewhere in the middle with copious amounts of ram stuff can be fast once up and running, but it seems every app either wants to load from web on every step or tries to index your drive on every keypress.

The accuracy figures in TA are kinda low - 99.7 for the top one, averaging out at 98.5%.

Anyone has some idea what is this measuring?

Bit accuracy (way too low)? A full disk read 100% error free? The actual accuracy really depends on the quality of the disc, is this measured with a reference disc?

3D OpenStreetMap 4 years ago

Tried ground elevation, seems to be broken.

All buildings started floating hundreds of meters above the still flat terrain.

USA hopefully learned their lesson (over the several proxy wars). Now will Russia?

Yes Putin is the dictator, but the problem started when the people allowed him to become one. Now his "strongman" ethos does not allow him anything but push on. Trump would probably do similar things given time. Buy US was sane enough to push him out when they still could.

Also I think it's somewhat human nature to go help the side you sympathize with when an conflict occurs. We just need to learn to be more civilized about this, throwing army at the problem has very poor track record.

Wine is more like a re-implementation of windows Userland using a different kernel (and graphics libraries).

Since the hardware is all the same, there is nothing to emulate or compile.

Or from the other direction - windows NT contains a re-implementation of the win16 API. Is that an emulator?
