This is similar to `Box::into_raw` in Rust `std`. It destructs the RAII struct into a raw pointer. After that it's pretty much expected that you are responsible for cleanup.

Most hosts will generate both a stable and a temporary address when using SLAAC. The temporary address will be used for outbound traffic but the stable address will accept incoming traffic. So there usually is a stable ULA or link-local tha

"Widespread" was maybe the wrong word, I was mostly imagining virtual memory on servers. Currently, not all 64 bits are available for user-space VAs. Even with Intel's 5-level paging you can "only" get 56-bit (128 P

It's quite intriguing to think about when and in which applications this bit-length churn will end. For example, 64-bit UNIX epoch will work for 292 billion years. That's longer than the age of the universe and obviously enough. M

Generally, you can just give the disk to someone else. The physical disk contains the license key for the game. The issue is that all modern games need to be installed on the internal SSD. So you're not playing of the disk, you're

To me the the final dystopian level is data ownership. It's already annoying to use your iPhone as a primary camera without paying for iCloud storage. Imagine if you could only view your own photos after you've paid $10/mo fo

The issue is that `~Copyable` is basically an anti-protocol. With a generics definition like `some Drinkable` you are _restricting_ the set of suitable types (from any type to only the ones implementing `Drinkable`) which then _expands_ the

Fair point. Though, the code in question was a trait definition.

Well, you can't use the `async` keyword version if you need the `Send` bound. Imo, Rust should introduce some syntax like `async(dyn+Send)` that desugars to `Box<dyn Future<Output = bla> + Send>`. This solves most of the as

That's assuming you're trying to avoid DSC. With DSC you can easily get 1440@240Hz even on DP1.4. Most monitors don't ship with DP2.0, because it's just not necessary. All modern GPUs support DSC, so monitor OEMs take th

As this case shows, it takes over a decade to successfully litigate a pretty obvious copyright violation. So Microsoft feels quite confident in paying for you.

I'm going to add: Length. Six foot USB-C cables with USB 2.0 are cheap and easy to find. More than three foot for a 40Gbit/s USB4 cable requires active components which are expensive and usually not future-proof.

That seems about right. > which is also optional, I believe Compression support (DSC) is mandatory since DP 2.0. So running DisplayPort Alt Mode 2.0 (which is basically "DP 2.0 over USB-C") should guarantee DSC support. The ne

> Cost per MW: $4.5m That's quite high. Here in Germany they assume 530-800€ per kW_peak for a utility-scale ground-mounted system (2021) [0]. You can add additional CAPEX for inflation and expansion of the grid, but <$1500 per k

Apparently, after removing M2M-SIMs (smart-home, card-terminals, etc.) you end up with 107m active SIM cards. That seems reasonable: Company-issued phones, LTE-Routers, some undercounting of M2M, and gerneral churn (I changed provider so I

Most consumers only have 1-2 NVMe drive and a GPU. So I presume OEMs don't want to have an M.2 slot buried under the GPU. On AM4 ATX-boards slot 0 is often then primary M.2 slot. Slot 1 the GPU and slot 2 is either empty, or the CMOS b

Some helpful explanations in there! Though I think the closure example doesn't actually show capturing context. It's just a partial function application unless you count the literal '5' as a local variable.
