Lazier than you think! You almost nerdsniped me into seeing how fast I could whip up a crawler but then I checked the search and found out it can find comments and use a custom date range.

This one seems to fit. Happy I've never had reason to write one like it.

    awk '{ k = $1; sub("^[^ ]* *", "", $0); d[k] = $0; } END { print d["Title"], "by", d["Artist"]; }'
Personally I'm a bit of a sed fan

    sed -nE '/^Artist/{N;s/^Artist +(.*)\nTitle +(.*)/\2 by \1/p;}'

Ctrl-F free - Phrase not found

What a coincidence.

I'm not a card carrying FSF member but that seems like a deliberate omission from the admittedly brief history. However also fairly off-topic as criticisms go.

A maintainer willing to reject contributions is a good sign to me - BDFL with a vision prevents mission creep and associated ills. The right to fork alleviates most of the negatives.

> the windows partition was using hardware-bitlocker

That sounds way too exciting, even without that involved I keep my Windows install on its own disk.

> I personally use a boot-stub based booting method with my own SB keys

Same here - stub, kernel, initrd and embedded cmdline all in a signed UKI on the ESP. I do encrypt my root however, so I wouldn't go as far as "painless" for the grub->efibootmgr switch (but I also switched initramfs generator so... always keep a rescue stick around).

But it's all about ownership and trust. I control the keys - hence I am the owner of my computer - and I don't trust e.g. Microsoft[1] to not eventually try to fuck me over. But that's not the important part.

> Also, I don't understand where remote attestation entered the conversation here, and I also don't see why that can't be a community based thing (al la let's encrypt is now everyone's CA) where you can choose your providers or even roll it yourself.

Remote attestation is mentioned five times in TFA and is where this can get really pernicious - indirectly limiting user choice because $safety_critical_industry (e.g. banking) only allows "the corporate keys" (likely including a few Linuxes too, but something like Gentoo couldn't be). They'll even have very good and completely valid security reasons for not allowing arbitrary user keys, but they'd lock me down to approved choices remotely. A reverse AGPL if you will.

Of course, workarounds will exist: "just multiboot", "just use multiple devices", "just choose the bank that allows you to whitelist your key" (assuming there is one, it's nice to dream) - but user freedom is reduced without malicious intent being strictly necessary anywhere in the process.

That's focusing on the negatives with my paranoiac hat on, of course.

Now that's the most ominous title I've read all year, and it's a piece in favor of it? Maybe I've just read too many dystopian novels, but come on.

I'm all in favor of secure boot as long as I can enroll my own keys, but remote attestation gets scary quickly.

> Another reason to prefer the cat variant is that it lets you actually string together a normal shell pipeline.

That's just as easy with dd, decompress|dd is especially useful:

xzcat linux.img.xz | dd of=/dev/sdb bs=1M

Throw pv in there if you want to.

> here are two ways to create a 100 MB file containing all zeroes

And here's a better way: truncate -s 100m zero.img

For more X is also a Y-style fun, check out PoC||GTFO - "This PDF is also an MBR boot sector" is just the beginning.

> I've read that the PCEngines struggles to keep up with network traffic in excess of 100Mb/s.

For reference, quick iperf3 TCP tests on my APU2 (cpu[0123]: AMD GX-412TC SOC, 998.27 MHz; em[0123] at pci[1234] dev 0 function 0 "Intel I211" rev 0x03):

LAN host <-> APU: ~410 Mbps

LAN host <-> APU (over WireGuard): ~140 Mbps

However, I've put em[123] together as a veb(4) switch without pf involvement and two LAN hosts will get almost the full gigabit between them over that. Would need something bigger if I had a faster uplink or more complex LAN requirements.
