Pretending your laptop is a screaming fast workstation and compiling C++ code on all cores can use quite a bit of RAM. (I have a MacBook Pro that is only around 10% slower at this than an AMD workstation. The workstation has considerably hi

On a quick read of the paper, it's incoherent (pun intended). It seems to conflate quantum states with classical vectors, which thoroughly loses both the source of the exponential speedup in Shor's algorithm and the difficulty of

I’ve only tried doing a phone repair per iFixit’s instructions once, and the instructions sucked. They explained in excruciating detail how to take the phone apart and then the instructions just ended. No details on reassembly.

What’s wrong with fwupd? I’ll admit that that the CLI is not exactly awesome, but it seems like a fairly clean implementation of the actual UEFI spec for updates.

belated edit: My comment about “whatever, the temperature is high” is silly. The mean photon energy is about 2.7kT, which scales in direct proportion the interest bits of the Maxwell-Boltzmann and Bose-Einstein distributions (see [0] and [1

I haven’t tried to look up the history of this claim, but here are some guesses: 1. There’s a sort of diffusion process going on. Photons from the core have some mean free path as a function of radial position (and, obnoxiously, of waveleng

Sometimes the ISA matters. For example, modern ARM has flexible and lightweight atomics, whereas x86 is almost entirely missing non-totally-ordered RMW operations.

Check your generated code. Most compilers assume that packed also means unaligned and will generate unaligned load and store sequences, which are large, slow, and may lose whatever atomicity properties they might have had.

Entire libraries are a weird sort of exception. They fundamentally target a specific architecture, and all the nonportable or version dependent data structures are self describing in the sense that the code that accesses them are shipped al

Lots of reasons: The code is not portable between architectures. You can’t actually define your data structure. You can pretend with your compiler’s version of “pack” with regrettable results. You probably have multiple kinds of undefined

There are a whole lot of tools intended for human use that I would use much more effectively if I could rotate my wrist repeatedly in the same direction.

A humanoid human will fall over too if pushed into a sufficiently awkward corner. It’s a fundamental problem with things that aren’t statically stable and need active stabilization.

Those intermediate layers are usually part of the artifact. Try exporting an image with docker save and investigate what’s inside. This is all documented in a mostly comprehensible manner in the OCI specs. I’m afraid you’re missing my point

There is something wrong with the industry in which we think that, when a production build requires SSH keys, the problem is that the keys might leak into the build artifact.
