I recently bought one of these air quality monitors and got to take it out for some measurements!

I'll share some findings in this thread.

CCing @CO2Guerrillas here, in case they would like to share.

Just published 15,000+ words on security keys. 🔐📱💻

With SIM attacks at their highest, now is a great time to take a closer look at your online security.

Removing SMS from your two-factor auth is a start, but authenticator apps have downsides too...

Just look at these headlines from recent SIM swap and port attacks.

It's all too established for attackers to find ways to socially engineer control of your phone number and start gaining control of your accounts.

I first talk about some general security tips.

Unfortunately not all websites let you remove your phone number from accounts.

You may consider migrating your phone carrier to @googlefi , which requires email account access to do anything (and can be locked down with security keys and even Advanced Protection)

Beyond SMS, I talk about issues that TOTP authenticator apps (the code generators) have as a form of two-factor auth. They're so, so much better than relying on SMS for your second factor but they still have issues like utilizing shared secrets and lacking phishing prevention.

Enter security keys!

Utilizing public key cryptography they don't have any shared secret between the client and the server. They prevent phishing by taking the website domain into account.

Even if you get tricked by a clone phishing website, your key won't.

Mark Zuckerberg on NYT story: "To suggest we weren't interested in knowing the truth or wanted to hide what we knew or wanted to prevent investigations is simply untrue."

Facebook says it will take a couple of questions on the article but wants to focus on (looks at notes) its transparency report.

Good luck with that folks.

Now Mark Zuckerberg is running through all the tactics it's deploying to clean up the platform (you know like they should have years ago).

What every Facebook user should be reading in the

Most software founders, particularly in B2B, need to get radically better at sales. @Steli , who is the best person for explaining the scrappy stages in the beginning and then building out a team with scripts and processes, wrote a guide to:

For technical founders it is irrationally, obscenely hard to reverse years of programming (ba dum bum) that sales is a value-destroying activity. Sales is CLEARLY a value-creating activity, contingent on you have a value-creating product.

The world will not drop what they are doing to adopt your work. This is particularly true in B2B, where simply building a better mousetrap won't overcome the activation energy required to get people with additional non-mice problems to prioritize changing mousetraps today.

This is very non-obvious for founders because founders are not often people who *want* to be sold to. We often come from a background where trying out tools is a bit of a fun hobby. We like looking at all the options, making charts, and ripping out partially complete tests.

"This week I unsuccessfully trialed four software options for automating that thing that has been killing us. Our actual production process remains the same as last week. Don't worry; this was a great use of time." is not a thing you want to write in a progress report to manager.

Elastic didn't really relicense ElasticSearch. It forked it.

🧵 A thread.

There's a lot of talk in the open source community about the cost of forking.

2/18

- "Forking is best avoided."

- "Forking is a last resort option."

- "Forking is like a nuclear weapons. It's a defensive threat."

3/18

Forking is seen as impractical and extremely expensive.

And that's a Really Good Thing(tm).

It's a forcing function for figuring out solutions that are broadly acceptable across the community.

4/18

The thing is, the cost of forking is mostly a function of three things:

1⃣ the size of the community that you can bring along with you,
2⃣ whether you need to rename your fork (who owns the trademark), and
3⃣ how much infrastructure you need to rebuild.
