Fun experiment: started 100 Firecracker microVMs on a single bare metal server, and the 101st took less than 5 seconds to warm up 🚀 ...and at least 15 of those VMs were running K3s ...while the resource utilization stayed < 30% via iximiuz Labs ❤️‍🔥

And the coolest part probably is that the server that powers at this moment isn't that powerful! i7-8700 CPU 3.20GHz (6 CPUs, 12 threads) and 128 GB RAM

Any of this open source? I’d love to see the process you use to make the firecracker disk images that allow the boot to be so quick!

My process is not much different from what ignite does It’s a good old “take a dockerfile and build it to a folder, then dump a kernel on top.” I described it a while ago in this blog post

What do you use for launching firecracker vms? Not ignite?

It’s a 100% custom daemon. Much like ignite but with a REST API and tailored for multi-VM playgrounds (so a bunch of extra networking magic).

Aaron Rai took at least 1 minute 30 seconds over this putt while Nick Taylor waited patiently on the tee and I nodded off. Paralysis by analysis!

NEW: Metal barricades were left down which led to the horrific New Orleans terror attack, according to a witness on CNN. A witness has now come forward and says the hydraulic metal barriers were down during the attack. Here is everything we know: - The man rammed his truck into a crowd on Bourbon Street - A “black flag” was spotted on the back of his truck - After running over dozens of people, the man got out and started firing at people - The man was then shot and killed by police - At least 10 people are deceased and 30 more are injured - FBI says they are investigating the incident as an “act of terrorism” - Hydraulic metal barricades were left down, according to a witness “We have these hydraulic steel barriers from past events… Those barricades were not up, period. They had the flimsy orange ones that you could just push over with your finger.”

More cuts doesn’t mean ‘bad’, but when you make the viewers eyes go left/right/left/recenter, on top of using multiple cuts on a single action - like running up the ladder, it makes the scene feel less impactful and floaty. (Via

Those 15 seconds of awkward silence between Sandra’s introduction and the track beginning to play weren’t a technical glitch — they were the sound engineer giving the longest mercy warning in public access history: “15 seconds to change the channel…5…4…3…2…1…Godspeed, brave souls.”

06/05/1997: It’s easy now to forget the impact Michael Owen had. His pace and finishing were incredible. He came on as a sub at Wimbledon, aged 17y 143d, and took less than 15 minutes to score. In just over a year, he was starring at the World Cup at 18! Phenomenal.

I think that the euphoric phase of the bull market is just getting started and could last for at least 6 to 12 months. Rather than looking at a single asset and a single indicator, I'm looking for confluence across #Bitcoin #Ethereum #Altcoins $IWM $GOLD and China/Japan markets.
