Such numbers are called "normal numbers". Pi likely is one based on all the digits we've computed for it, but we don't have any way to prove a given number like pi is normal or not. Relevant Numberphile video: https:&#x

You can disable most of these things in user.js. See https://github.com/arkenfox/user.js (née ghacks.net user.js) for an example. The next problem is FF generates random profile names by default ( ~/.mozilla/

For systemd services, there's also the option to use the service unit directives that systemd provides to limit caps (CapabilityBoundingSet, NoNewPrivileges, etc), filesystem access (ProtectSystem, ReadWritePaths, etc), other "sys

You can start the server as a user session service if you have a service manager for that, like systemd, instead of needing to do it manually. For systemd specifically, tmux also supports socket activation for the server since some time ago

Maybe. From what I know of sbctl I think it would be fine for a beginner, but I can't say for sure because I use my own custom setup, not sbctl.

Or a single GPU that supports SR-IOV, but AFAIK no consumer-grade GPU provides it.

You could if you want to, but if your distribution provides a UEFI bootloader (shim / grub / systemd-boot / whatever) signed by the default MS-trusted cert, or you're willing to set up everything yourself with your own c

Or worse, the knobs don't exist because Daddy knows what's best for you, and you can't have the source to implement those knobs yourself either.

jemalloc also has its own funny problem with threads - if you have a multi-threaded application that uses jemalloc on all threads except the main thread, then the cleanup that jemalloc runs on main thread exit will segfault. In $dayjob we u

The mimalloc crate just provides the GlobalAlloc impl that can be registered with libstd as the global allocator using the `#[global_allocator]` attr. The underlying sys crate provides the binding for mimalloc API like `mi_collect`: https:

And even if one wants to use dependencies not available as a distro devel package (or as a fallback to missing distro devel package), things like meson and cmake make it relatively straightforward to use vendored dependencies.

Is it the logical end that we have custom cores everywhere? Yes RISC-V is open and relatively straightforward to implement (coincidentally I did just that over the weekend in a circuit simulator game), but I can also see economies of scale

For anyone else like me who's only played the online versions and was really confused by the article: the physical game does not completely randomize the positions of red and blue cards but has a fixed set of possible configurations -

Any company which goes to the lengths of setting up an IRC server would find it trivial to also set up a bouncer and search index for that server. That said, these days a Matrix Synapse instance would be an easier choice.

A fallback to hardlinking would work for a lot more filesystems, though of course it would be limited to files that are completely identical rather than any identical extents / blocks within files.

As of 2020 (when I stopped using F# and .Net in general), the CLR only had inheritance and F#'s enums were actually implemented using inheritance. Eg Some and None were derived classes of Option class. You would see it if you inspected

The earlier levels are like that, but the later levels have a lot more leeway.

PinePhone SoC (Allwinner A64) does have the hardware needed for verifying boot via TBBR. It's just that no person or distro uses it for that because the key can only be written once. Also IIRC it's vulnerable to bus snooping.

Yeah, every time I update the UEFI it pops up a warning that the TPM will be cleared and I better have disabled Windows Bootlocker before I did this. The warning also goes away within a fraction of a second because the PC reboots which is n

That said, it does require more care when you do OS updates or UEFI updates to remember to update the TPM sealed secret with the new measurements. Windows and Linux both have the former automated so it should generally be fine. UEFI updates

Supported hardware doesn't matter because they're comparing the compiled binary size, not source code size. The u-boot binary you'd compile would also only have the stuff relevant to that particular hardware compiled-in. If y

I doubt any of those use dockerd. They likely all use containerd directly.
