I lost account of how many switches, routers, USB-C adapters, cables, etc. I'm still running more tests and some devices haven't arrived yet, but 8 out of the 10 things I tested just couldn't handle 5Gbps. I'll revisit this thread with some learnings later on. First lesson is that 1Gbps is standard. 10Gbps is standard. But if you go for 2.5 or 5, all bets are off and you may find all kinds of problems.

I tested 5 USB-C adapters. Only 2 managed to work.

Me: Can I have a faster home internet?

@ZiplyFiber: But you already have 1Gbps both ways?

Me: 🥺

Ziply: Sigh... OK Image @ZiplyFiber It goes up to 5Gbps but the internet and my router need to both be in a good mood.

I have a fun story on that:

Back in the day, my friend @HaishiBai2010 and I were working on some demos for Russinovich for Build, to show Service Fabric. One of the demos was a game built in Unit, like Asteroids. We had just like two weeks to build the thing. NO PRESSURE. The game was supposed to use XBox controllers connected via USB to the KVMs because every machine had backups, so everything was orchestrated by KVMs.

WELLLLLL....

Nearly 3,000 people died in 9/11

More than 360,000 civilians died in the "war on terror" that came after that. Always important to consider who was in charge of what decisions that led to how many fatalities.

I ordered a litter robot thing, and I didn't realize how enormous that is. It arrived in a 3 foot tall box.

I am now terrified that when wife comes downstairs, she will see this box and freak out. This thing is ginormous

In Brazil we use a technical term for this:
Color-of-a-donkey-when-it-runs-away

(I'm not making this up. It's the name we use) So everybody else has the same term, but with a dog.

In Brazil we chose a donkey instead.

This tells you everything you need to know about Brazil.

Last night wife started to ask all these random questions about the universe. We talked about the big bang, dark matter, dark energy, how stars eventually run out of fuel, entropy... She then finally asked:

-So there's no point in anything?

-Nope The universe doesn't care about your judgment of my cynicism

A scientifically accurate version of Back to the Future where as soon as he goes back in time he finds himself floating in space because Earth has more moved far away.

Then he dies without air and the movie ends. "Ah but the Flux capacitor calculates and repositions the car"

It would arrive at a different velocity.

Earth moves at 67000mph. It also rotates at 1000mph. The car would either be instantly crushed, launched into space or burst in flames.

I understand you must have many questions about the whole dynamics of GameStop, naked options, dogecoin, SEC policies, market volatility and potential correlations with your 401K, so here's a quick explanation:

¯\_(ツ)_/¯

Do you all realize the irony of something being called a hedge fund and then being obliterated exactly because what they didn't do was... well... hedging their positions? Finance sector will always find creative ways of blowing themselves up with TNT unless they are strictly supervised.

It is interesting that nobody is talking about it.

In most enterprise companies we would be burning all devices by now and trying to track who had access to what. What I would love to understand:

From the decision to open the gates, to let them in, to not send reinforcement, to not arrest and background check every person who got there, who made those decisions and what was the rationale regarding the national security?

1-Go to account.live.com, security and view my activity

2-Freak out when you see how many times people try to login into your account from all over the world

3-Take the opportunity to ensure your 2FA is up to date, don't use phone/SMS (use an app), change your pwd, etc. When I say don't use phone/SMS I'm saying explicitly remove that as an option there.

Also send a complaint to your bank if they don't offer a stronger 2FA than just text messages. They should.

Boy where do I start...

Once I accidentally stepped on the foot of the New Zealand Prime Minister while boarding the same flight. One I crashed into the car of a famous Brazilian musician, spent hours chatting with him and had no idea who he was until the police officer recognized him.

Yes, Amazon, I totally want a proprietary network to circumvent all my network security to go create a rogue peer to peer based network with my neighbors, that's definitely a think I would love, thank you. I mean, what could go wrong

My Boox NoteAir arrived and I'm in love. Still setting it up but I already like it so much more than the Remarkable. Apps! You can install OneNote! You can use a Bluetooth keyboard! OMG

The screen is gorgeous and it's super thin

boox.com/noteair/ Question is whether I should keep it distraction free or install communication apps in it... hmm....

So I receive a status update from USPS saying that my package is held at the post office "due to my request" (which I didn't make). I go there and find the busiest post office that I have ever seen. HUGE line. I wait there for nearly one hour. I then realize that half of that queue was people in the same situation, they were told that they requested their packages to be held. None of them did.

Dear developer, is your manager complaining that your code has too many bugs?

Demand a recount right now! How can you explain that the first unit tests all passed and then all the integration tests started failing later, huh? HUH? TEST FRAUD, I SAY

Funny thing happened to me this week:

I realized I was late for a meeting where I was supposed to do a presentation so I connected on Teams but I couldn't hear anything because a bunch of people were in my home office talking. So then I told them to get out, put the headphones And then I could hear people from all over the world on the call, speaking English, Portuguese, Japanese, etc. They were a bit annoyed that I was late. But then my mic didn't work!

Then I remembered that I had another mic in a different room, so I went there.

Today, @migueldeicaza and I will be watching the iPhone event.

Will it have a larger screen? A faster processor? Maybe, dare we dream, even USB-C? Personally I don't know if I can handle all that innovation but here we go! I am ready, baby!
