Disease has always been a bigger cause of death in the US than guns.

• 2019 US gun deaths: 39,707
• 2019 US heart attack deaths: 659,041 (17 times higher than guns)
• 2022 US COVID-19 deaths: approx 244,000 (6 times higher than guns in 2019)

Try going to http://0.0.0.0:8080/ in your web browser (replacing the 0’s with your public IP address), on your home connection. If it doesn’t work, it means that your port forwarding is probably not working. If the page loads correctly, it means your port forwarding is working correctly, and the problem is probably your ISP doing port blocking.

Yeah, this. It would be tasteful to get a gift card to any local coffee shop, or Target, or one of those $20 Visa gift cards, though they have like a $5 overhead just to activate them.

Homemade pastries are a bit weird if you don’t know someone that well, and store-bought pastries are hard if you don’t know what they like.

As far as I’m aware, Trump plans to remove all immigrants, whether documented or not, and even green card holders. I don’t think he will have much luck with it, but maybe I’m wrong.

Start applying for jobs outside the US. Finding a job is usually the longest part of moving.

You may want to try applying for citizenship at the same time, assuming you even want to stay for 2025-2028.

I’m speaking as a US citizen whose life would be improved by your presence in the US.

In my system, the raid arrays seem to do periodic data scrubbing automatically. Maybe it’s something that’s part of Debian, or maybe it’s just a default kernel setting. I don’t think it helps much with data integrity – I think it helps more just by ensuring the continued functionality of the drives.

When it’s running, you can type cat /proc/mdstat to see the progress.

That command will also show you if there is a failing drive, so that you can replace it.

Sure. First you set up a RAID5/6 array in mdadm. This is a purely software thing, which is built into the Linux kernel. It doesn’t require any hardware RAID system. If you have 3-4 drives, RAID5 is probably best, and if you have 5+ drives RAID6 is probably best.

If your 3 blank drives are sdb1, sdc1, and sdd1, run this:

mdadm --create --verbose /dev/md0 --level=5 -n 3 /dev/sdb1 /dev/sdc1 /dev/sdd1

This will create a block device called /dev/md0 that you can use as if it were a single large hard drive.

mkfs.btrfs /dev/md0

That will make the filesystem on the block device.

mkdir /mnt/bigraid
mount /dev/md0 /mnt/bigraid

This creates a mount point and mounts the filesystem.

To get it to mount every time you boot, add an entry for this filesystem in /etc/fstab

The man page at https://btrfs.readthedocs.io/en/latest/mkfs.btrfs.html says:

RAID5/6 has known problems and should not be used in production.

So those profiles have unknown, unspecified problems.

But btrfs is safe on top of md-based raid1/5/6. It also has the advantage that you only need to encrypt one volume.

Pretty fucked, but not as fucked as Ukraine, Palestine, Lebanon, or Taiwan.

NATO will be fucked for a while if the US withdraws, but other NATO countries may ramp up military spending over time.

This situation is a worldwide danger. The US is/was a world power, it has/had the largest national economy in the world, it has the largest military in the world.

Previously, we could be concerned that democratic countries (including the US) weren’t putting enough pressure on authoritarian countries (like Russia, China, and North Korea) to improve. Now we have to worry that the US will actually become a fully authoritarian country, like Russia or China.

I acknowledge that it was well received, but it was from 2019.

Elder Scrolls 6 will no doubt be polarizing, with some calling it the game of the decade, and others saying that the TES formula just doesn’t work anymore. (The game might also just suck.)

I don’t know much about client certificates, because nobody ever used them. All I know is that they are decades older than passkeys, and “certificate” implies there is a public-private keypair, just like in a passkey.

What are the benefits of a passkey over a client certificate?

The easiest way to disable unnecessary services is to uninstall them with aptitude, or whichever package manager you like. Try terminating services one by one, and see if anything bad happens. If nothing bad happens, you can probably uninstall it. On the other hand, if the system does get wonky a reboot should fix it. Or, you can research the services by name and decide whether to uninstall them. (avahi-daemon for example is a good idea to uninstall.)

To make the GUI not run, uninstall your display manager (gdm, xdm, nodm, or whatever) and uninstall your xorg server or wayland server. There may be GUI programs remaining after that, but they will only be consuming disk space, not RAM or CPU.

If the battery is old and holds little charge, you may save a few watts by removing it and throwing it away, instead of letting the system keep it topped off.

Get a power meter, such as a Kill-a-watt device. Then, experiment with different settings. If it’s consuming less than 30 watts, you’re probably fine. If you live in the US, one watt-year is about one US dollar (or a little more), so for every watt it consumes, that’s about how much you will pay per year for its electricity.

Why is the antivirus software detecting my Cortex-M3 binaries as dangerous to an amd64 computer? Happens on Windows 7 through Windows 10, across 3 different employers.

And how do I submit my builds to Virus Total if they’re getting deleted as soon as they come out of the linker?

Using a VPN (like Tailscale or Netbird) will make setup very easy, but probably a bit slower, because they probably connect through the VPN service’s infrastructure.

My recommended approach would be to use a directly connected VPN, like OpenVPN, that just has two nodes on it – your VPS, and your home server. This will bypass the potentially slow infrastructure of a commercial VPN service. Then, use iptables rules to have the VPS forward the relevant connections (TCP port 80/443 for the web apps, TCP/UDP port 25565 for Minecraft, etc.) to the home server’s OpenVPN IP address.

My second recommended approach would be to use a program like openbsd-inetd on your VPS to forward all relevant connections to your real IP address. Then, open those ports on your home connection, but only for the VPS’s IP address. If some random person tries to portscan you, they will see closed ports.

Freedom of Speech does mean freedom from consequences, at least from any government that recognizes that freedom of speech. The phrase, “Freedom of speech is not freedom from consequences” refers to the ability of private entities to take negative actions against speakers engaging in free speech, simply because those negative actions were within the private entities’ rights all along. For example, the ability of any Lemmy instance to ban anyone they want.

Regardless, speech that is actively harmful, is false, or meets certain other circumstances (depending on which government you’re looking at) may not be recognized as covered free speech. Tucker Carlson is probably about to do a bunch of speech that is not covered by freedom of speech, which is why the expected sanctions will be justified.

Cloudflare seems to incorrectly classify my Internet connection, which is a residential Internet connection going to my house, as a datacenter connection or VPN or something.

Many websites that use Cloudflare give me endless captcha forms. As soon as I solve one, it demands another, and never lets me access the website.

Sometimes I solve one captcha, and then it says I’m blocked forever for sending automated queries, even though I filled it out correctly. The error message is: “You are blocked.”

Sometimes it lets me in after one captcha, but I still resent having to enable Javascript for these assholes just to access a site that doesn’t otherwise require Javascript.

Sometimes Cloudflare adds extra security to certain pages, just for me. The developers of the website didn’t program it to handle this extra security, so the site fails for just me, and the site developers don’t believe me, telling me I have a browser problem (in three different browsers, which I can fix by using a proxy). For example, when the site’s javascript has my browser to do a CORS operation, the first step is the browser sending an OPTIONS request. However, the extra security of the proxy introduced by Cloudflare responds slightly differently from the actual website, so the site breaks.

Cloudflare uses a holistic approach to deciding whether you are a legitimate user or a bot. In other words, they use every single possible piece of data they can get on you, including tracking your visits across other Cloudflare sites. They do discriminate against certain user-agent strings.

Cloudflare completely blocks many Tor users, even from having read-only access to a site.

When you ask Cloudflare why your IP address is blocked, they falsely claim that it’s a setting created by the website admins. I strongly suspect that this setting is something like “use Cloudflare™ Adaptive Security™” and probably doesn’t explain to the site admin that they’re blocking large quantities of innocent users.

Cloudflare has previously used Google Recaptcha, which has a ton of problems (tracking, accessibility, training AIs that will make my life worse).
