If you're in IT, I highly encourage you to write a blog.

Here are 17 reasons why you should be blogging.
🧵👇 1. Don't think of the blog as some new profound insight that makes you look smart. Instead, just write notes to yourself. If you make the blog useful to you, it'll be useful to others.

20 lessons learned in my 10 years working as network security engineer. My job was to configure and manage firewalls for customers.

🧵👇 1. Always have a backout plan. If you're going to be making changes to production equipment, expect it to go all wrong one day and you'll be ok if you have a plan for that. If not you'll be burned.

You. Yes you. You are the target of a massive disinformation campaign.
Corrupt, evil powers of the world do bad and nasty things. And their tactic is to then flood the world with tons of fake news. They don't have a good way to spin it, so they drown the truth. /thread These evil powers will try to delegitimize journalists who report the truth. Journalists will be attacked, arrested, sometimes killed.
Journalists and investigators are on the front lines of this information war. And they're our only hope for finding the truth.

Those of you who believe in free will. I have some questions for you.

1. When you suddenly wake up at 2am and can't stop thinking about work and can't go back to bed for hours and hours because your brain won't shut off. Would you say you have free will during that time? 2. When you really don't want to do something but you know you have to do it so you do it, would you consider that to be free will?
For instance suppose you're a parent and you've got a sick kid vomiting in their bed, all night. Then they wake you up at 6am hungry and needy.

Yesterday Spotify bought Megaphone for $235 million.

Megaphone is my podcast hosting provider, so here are my thoughts.

/thread Megaphone is unique in that it can do "dynamic ad insertion" (DAI). That is, I can swap ads in and out without having to mess with my original mp3 of the show. Just set a time mark of where an ad will go and it's stuck in. It's quite amazing technology.

I asked @TypeErr0r what are some ways to actively be anti-racist. Here's a list of things she told me we can do today, and every day.

#ShareTheMicInCyber is happening! And I can't wait to introduce you all to Alexia aka @TypeErr0r.

To start let me tell you what I know about her.

/thread I met Alexia at a security conference the day after I launched the podcast, and it only had 4 episodes then. She was the first person I met who I didn't know at all, who told me she listened to all episodes and wants more. As a podcaster, this is something you never forget.

My (naive, and incomplete) understanding of what it means to "defund the police". A thread. I was watching the latest vid by @DonutOperator which says something like "if we defund cops, we'll have less trained, and worse cops". Which sounds true right. A police force with more officers and money means more training and you can be more selective with who joins the force.

Wanna know everything about websites port scanning you? Here I put everything I know into a blog post. tunnelsup.com/browser-portsc… I found the company supplying this to eBay is @ThreatMetrix. risk.lexisnexis.com/products/threa…

After further research there's two main reason eBay is doing this.

It boils down to fraud detection.

As you may have noticed the ports it's checking to are open are RDP ports. VNC, TeamViewer, Logmein, etc.

One reason they check this is to see if the user's PC is being controlled by someone else. There seems to be a lot of scams going on now where attackers get control of victim PC and go buy something through their logged on account.

I learned a lot tonight. This is what dev tools tells me in Edge by just visiting eBay.

The website is port scanning my laptop, bypassing my firewall, and doing it in/from the browser.

It checked 14 ports.

Let's discuss. 1/5 If this had conducted a full port scan on my internal network and reported the results to eBay, is that illegal? This is not portscanning the internet, it's port scanning my computer, which is behind a firewall in my home. Is that illegal? Probably not but it's at the line.

What if, in the future, we had devices to monitor our biophysical state. Where it can detect when our brain is making oxytocin, dopamine, cortisol, endorphins and provide immediate results. 1/5 And then, that gets paired with the Spotify AI algorithm. So Spotify now knows your sad, and knows the thousands of songs you love, and tries to create a custom song, from scratch, on the fly, to cheer you up. 2/5

Now's the time to prove it boss.

Awful Instagram ask Jack roundup 2020 edition.

I don't know what all this hate is about bringing a burner phone to Defcon is all about. I'm absolutely bringing one. For all the reasons below. 1. One year a speaker demonstrated a rogue AT&T cell tower on stage and asked people on AT&T to try to make a call and I did and my call got intercepted. I saw my phone number on the presenters screen!
