Perhaps a new #introduction is needed. I’m Nick Percoco. I’m the Chief Security Officer at Kraken. I’m responsible for all things security, IT, fraud and client support. I’ve been working in the crypto industry for 6 years and have 27 years of experience overall. What would you like to hear from me about on #nostr?

Are folks from Brazil here?

In Spring of 1995, I was a Linux user. I had been since late 1993 running Slackware. This was being done on a 386SX processor with 2MB of RAM and 20MB hard disk.
There started to be some chatter on USENET about Windows 95 coming out and how it was going to be amazing.
I wanted to see if I could get my hands on a leaked copy somehow. In 1995, the best place to find this was #warez on IRC. So I jumped into that channel and found a DCC bot offering up a beta version of Windows 95.
After going back to my dorm and installing it, since this was a beta version there wasn’t any network card drivers nor a TCP/IP stack. I had to get the DOS driver (3c509) and then the Windows 3.1 TCP/IP stack which was Trumpet Winsock to be able to DHCP an address from my dorm’s network and connect to the Internet with terminal tools like FTP and NCSA Telnet.
A graphical web browser didn’t come as part Windows 95. Internet Explorer didn’t come until the Windows 95 Plus pack was released later.
There were basically two main choices of web browsers at the time: NCSA Mosaic and Netscape Navigator, so I installed both.
I had been using NCSA Mosaic since fall of 1993 and was a fan - having developed a lot of websites for my university and also businesses in Chicago starting around 1994.
Netscape was innovating more than Mosaic and it eventually became my browser of choice for many years.
I remember being especially excited when Netscape added SSL support - prior to this most of what you did online was sent in clear text. SSL would enable web forms to take private information like credit cards with less risk to compromise at the network layer.
I didn’t have a credit card in 1995, so I went down to the quad at Illinois State University and found a table with some kids giving free beer koosies if you signed up for a credit card.
It took a few weeks to arrive but received credit card with a $500 limit - with something like a 27% interest rate.
My first online purchase over SSL was on the Netscape website store for a t-shirt. It was a white t-shirt with a small Netscape logo in the upper left front chest and had the dragon named Mozilla on the back. It got lost in some move or closet purge - I wish I still had it. To me that transaction a monumental one in my life / career. It showed me a glimpse of what the future would be like. I spent the 2000s writing standards and building technology that further secure credit card use for the entire planet.
Connecting and building the Internet in mid-90s took a lot of motivation and time. Most parts of the experience just work today and we (including me) never thinks about it when doing everyday tasks. Those same parts would sometimes take several minutes or hours to setup just before you could begin to use them.
If you were a hacker with both patience and endless curiosity the 90s was a technical wonderland where you could discover and use technology that almost no one else on the planet was using, but someday would.

. . : : The Hacker's Manifesto : : . .
Another one got caught today, it's all over the papers. "Teenager arrested in computer crime scandal", "Hacker arrested after bank tampering"...
Damn Kids. They're all alike.
But did you, in your three-piece psychology and 1950's technobrain ever take a look behind the eyes of a hacker? Did you ever wonder what made him tick, what forces shaped him, what may have molded him?
I am a hacker, enter my world...
Mine is a world that begins with school. I've listened to the teacher explain for the fifteenth time how to reduce a fraction. I understand it. "No, Mrs. Smith, I didn't show my work. I did it in my head..."
Damn kid. Probably copied it. They're all alike.
I made a discovery today. I found a computer. Wait a second, this is cool. It does what I want it to do. If it makes a mistake, it's because I screwed up. Not because it doesn't like me...
or feels threatened by me...
or thinks I'm a smart ass...
or doesn't like teaching and shouldn't be here...
Damn kid. All he does is play games. They're all alike.
And then it happened... A door opened to a world... Rushing through the phone line like heroin through an addict's veins, an electronic pulse is sent out, a refuge from the day to day incompetencies is sought... A board is found.
"This is it... This is where I belong..."
I know everyone here... Even if I've never met them, never talked to them, may never hear from them again... I know you all...
Damn kid. Tying up the phone line again. They're all alike...
You bet your ass we're all alike... We've been spoon fed baby food at school when we hungered for steak... The bits of meat that you did let slip through were pre-chewed and tasteless. We've been dominated by sadists, or ignored by the apathetic. The few that had something to
teach found us willing pupils, but those few are like drops of water in the desert.
This is our world now... The world of the electron and the switch, the beauty of the baud. We make use of a service already existing without paying for what could be dirt cheap if it wasn't run by profiteering gluttons, and you call us criminals. We explore... And you call us criminals. We exist without skin color, without nationality, without religious bias... And you call us criminals. You build atomic bombs, you wage wars, you murder, you cheat, and lie to us and try to make us
believe it's for our own good, yet we're the criminals.
Yes, I am a criminal. My crime is that of curiosity. My crime is that of judging people by what they say and think, not what they look like. My crime is that of outsmarting you, something that you will never forgive me for.
I am a hacker, and this is my manifesto. You may stop this individual, but you can't stop us all...
After all, We're all alike.

I recently spent time with 150 8th graders as part of a career day at a local middle school. I spoke to them about my path in cybersecurity & cryptocurrency.
I was surprised by their interest & knowledge of #Bitcoin. Several of them, mostly girls told me that owned some. They asked questions about self custody and private key management.
I was expecting to start getting questions about the FUD we constantly hear (criminal use, climate impact, scams, etc). I heard non of that. Just engaging conversations about the utility, the value and global benefits of #Bitcoin. They get it.
I later realized these same kids are not on Twitter or Facebook and they don’t read or watch mainstream media. They are not inundated with anti-crypto FUD 24/7.
I didn’t know what to expect about my visit, but I now have more hope for the future.

I’d hope no one is zapping from their main wallet, but I’m sure there are some. A #[5] is what I use for only zapping. I have another lighting wallet for purchases and both are funded by my Kraken account when they get low. Nothing in social should ever be touching cold wallets.

Possibly. Depends on the crime. People get put into prison for reasons around the world that most reasonable people would thing isn’t a big deal. Highly skilled and one of those? Probably. Steal, Murder or Rape? No.

I don’t think we really know the answer yet.
If the free relays are not able to keep up with the demand and get flooded with spam, the paid relays may be able to provide better connectivity.
I believe I saw one that is broadcasting to / and filtering spam from popular free relays.
