Well, NVMe SSDs do get quite hot due to much higher data transfer speeds, and higher temperatures lead to faster flash memory degradation, although I have no idea how important it is in practice (probably on the order of an SSD dying in 10 years instead of 20)

FWIW I've been pretty happy with Senseair S8 0053 for my DIY stations. They're relatively expensive though.

Not affiliated in any way.

> co2 and pm should both go down with windows open.

Very much depends on where you live. I have a few DIY air quality stations with data being piped to Grafana. I just looked at the latest data, the average outside PM level for the past 5 months has been around 100 µg/m³, while inside it's around 10 µg/m³.

This spring happens to be pretty windy and this skews the outside levels down, otherwise the ratio would be much worse.

You'll be waiting on that gas station for hours for the payment to go through.

What else did you expect on a ~~hacker's~~ founder's site? Make a billion and retire before hitting 20, that's the goal.

Where are the exploits for TempleOS? Come to think of it, where are the users, and where do most security researchers direct their attention to?

I'm doing this also, and for the same reason.

>It's not uncommon that zooming will make the text smaller

At least in Firefox you can enforce the minimum font size through settings without using any third-party plugins or custom themes (look in about:preferences → "minimum font size"). I have it set to something like 16 or 18.

This doesn't fix the actual problem, but I gave up on trying to change the world a long time ago.

And you're posting anti-btrfs FUD.

Even if it's the only deployment in the world, it's more than "never". They provide strong technical reasons for using it.

What? They ship prebuilt zfs modules along with the kernel.

  # dpkg -L "linux-modules-$(uname -r)" | grep zfs.ko
  /lib/modules/5.4.0-70-generic/kernel/zfs/zfs.ko

With luck, this problem will soon be solved from the opposite direction:

So? Do you think filesystem metadata is stored in a magical pixie cloud, or on the same unreliable physical hardware where it can easily get corrupted, especially after a crash or an unexpected power loss?

I posted this link here already:

https://www.usenix.org/conference/atc19/presentation/jaffer

f2fs (at least in its state a couple of years ago) is/was a prime example of how a filesystem can get into a barely working state with massive amounts of data and metadata corruption, and not even notice it.

God I love this site. In case of a minor disagreement with someone don't even bother to think, just press "downvote".

scaladev — Thu, 22 Apr 2021 05:26:02 +0000

The other way to interpret this would be "it was the only filesystem to detect corruption on my malfunctioning hardware", because that's what usually happens in the last few years.

Or have you been using ZFS on the same hardware?

Has f2fs reliability changed much since this publication?

https://www.usenix.org/conference/atc19/presentation/jaffer

I'd be afraid to use it for anything other than throwaway test data.

I am sure that Western Digital (whom the author of this patchset works for) will be very interested in your opinion. He implements whatever makes business sense for WD, and not what some random forum commenter wants. I am not at all surprised that a storage vendor would want upstream Linux support for its upcoming devices before they're actually being sold in stores.

Wouldn't that draw more attention to the research patches, compared to a "normal" lkml patch? If you (as a maintainer) expected the patch to be malicious, wouldn't you be extra careful in reviewing it?

Do they only break for users in the United States? I've been using Firefox exclusively since about 2.0, and I've never had any of the Google projects break for me. Not once. Yet this seems to be a pretty common problem around here.
