How much sea level rise would it mitigate?

Labour intensive to round them up, test them, and design/build custom circuitry to hook up a pile of dissimilar panels. Then you have a pile of near EOL panels with reduced output and reduced reliability that is unlikely to ever break

As I understand it, you can configure git's difftool to be something more clever than line based

I wonder if browsers could design a heuristic to cache multiple items in one cache entry -- that is, instead of the website doing file concatenation, the browser dynamically decides to concatenate some resources in order to reduce the numbe

Any reason not to send the field rearrangement to upstream python? Or is it already done in later versions?

> resistivity of copper Could we use a superconductor here instead of copper in order to achieve further wire shrinkage? Eg, if it were to be operated in a datacentre where it's plausible to power the cooler needed to keep it cold.

That requires running a pile of nonfree/intrusive tracking code, and many people block this kind of thing

How might we prevent surveying the oceans from continuing?

If your hardware is impervious to rowhammer you'd get nothing

Anaconda is a bit of a dark horse here as a C package manager. Eg, in scenarios where you don't have root, or working on windows.

The sysctl can have three settings: 0 to do nothing, 1 to emit a warning, 2 to fully enable the patch that blocks argc=0. Use 1 by default as not to break userspace, let people opt-in to 2 for the additional security
133.
by kardos 5y ago
Indeed. But a sysctl to switch the patch on/off seems like the pragmatic solution

Yeah it's nifty idea -- no need for explosive hydrogen or scarce helium. If the polymer sheet is strong enough, I wonder if one could use it to wrap a sort of scaffolding (a shape like https://en.wikipedia.org/wiki&#x2F

And is that strength enough to put vacuum airships back on the menu?

Well not anytime soon, sure. But never ever and it's physically impossible? There is plenty of solar power around that could be used to power a smelter. Maybe someone will devise a new kind of ion-engine that runs on asteroid dust inst

I would expect the opposite: this product needs to be cheap to have a shot at supplanting plastic; extra process to remove all such contamination would work against it

Why stop there? Put a robotic claw on the drone and you have an autonomous plastic collection system. Then you can scale up to hundreds of drones and clean all the beaches

Hard to compete with a 4-byte lookup table, but for decoding the 256-byte table can become: return ((dibit | (dibit -1))>>1) & 3;

Horner's method is known to reduce the number of operations. Maybe the coefficients will turn out to be more favourable with this method? [1] https://en.wikipedia.org/wiki/Horner%27s_method

Agree; if a mispredict costs 15-20 cycles and a predict saves 4 cycles, does that mean we break even around 1/4-1/3 sequential?
145.
by kardos 5y ago
This works because we've arranged for the nodes to be sequential in memory, if we have the luxury of doing that then we could use an array instead of a linked list. Is there a scenario where this value speculation trick would work, whe

Not following the leaf-and-spine figure. 40x10G is 400G, but 4x40G is 160G, so how is this completely oversubscription free? Edit: followed the link, it is 2.5:1 oversubscribed

We are not far from cameras performing facial recognition and refusing to take photos of those on a "no photo list".

This could be big. A strong porting guide will go a long way. I wonder to what extent that could be automated?
