Important reminder, if you own a domain name and don't use it for sending email.

There is nothing to stop scammers from sending email claiming to be coming from your domain. And the older it gets, the more valuable it is for spoofing. It could eventually damage your domain's reputation and maybe get it blacklisted, unless you take the steps to notify email servers that any email received claiming to come from your domain should be trashed.

Just add these two TXT records to the DNS for your domain:
TXT v=spf1 -all
TXT v=DMARC1; p=reject;

The first says there is not a single SMTP server on earth authorized to send email on behalf of your domain. The second says that any email that says otherwise should be trashed.

If you do use your domain for sending email, be sure to add 3 records:
SPF record to indicate which SMTP server(s) are allowed to send your email.
DKIM records to add a digital signature to emails, allowing the receiving server to verify the sender and ensure message integrity.
DMARC record that tells the receiving email server how to handle email that fails either check.

You cannot stop scammers from sending email claiming to be from your domain, any more than you can prevent people from using your home address as a return address on a mailed letter. But, you can protect both your domain and intended scam victims by adding appropriate DNS records.

DuckDuckGo is now telling me to disable my adblocker? What even is this?

Today someone asked if I masked because I'm immunocompromised. I told them masking is just something I do now. It's a way to care for others and act in solidarity. If someone else masks, my mask means they aren't the only one

I cross post to everything except x, but I’m still really confused on people preferring Bluesky’s dubious corporate moderation over like volunteer friends and administrators, who we like… know. And who will alter policy to protect users.

There's really no benefit to giving up. Things will only get worse. Things may not get better if we try, but at least there's a chance.

Is this a subtweet?

white folks worried about Luigi Mangione’s violence spilling into their suburban, middle class lifestyles:

that you are worried that paperpushers like you may die in an attack is exactly why you have been told for decades to check your privilege.

there is no such thing as being innocent while paperpushing for fascists making money with eugenics-as-a-service.

you cannot absolve yourself with, “it’s just a paycheck”.

your whiteness, nor your paycheck, will protect you.

Tech journalists:

Soon, quantum computers will be able to break RSA by factoring arbitrarily large numbers, by way of [insert pseudoscience here]. Cryptography is doomed!!!

Meanwhile, quantum computers after decades and billions of dollars:

Sorry, I can't factor 35 yet.

I used to feel like I could always find anything I wanted with search engines. But, in the last five years that has no longer been true.

This is what Twitter looked like last time the federal minimum wage was raised btw……In 2009.
