There's technical debt, then there's technical subprime mortgages with exploding balloon payments.

Can’t wait for the Canes watch party at Lenovo tonight. I could afford to go to Vegas, but the vibes at the Lenny are going to be insane. Let’s go Canes! #soundthesiren

Erling Haaland has set the bar for what I expect out of celebrity guests from here on out. #SoundTheSiren

I was there last night and I've still probably watched this 20 times today. If anything this undersells the pop when Jarvy scored. My voice is still wrecked.
Worth it.

The Phinternet, y’all. It’s pretty great.
This is what I’ve spent the past month of my life building - designing and implementing the new Railway edge network & CDN from the ground up, now serving all of our traffic at 1 million RPS. I wrote about it here!

Did someone say the Canes are boring? Not sure, couldn’t really hear over this OLE chant …

I love everything about this DMA blocking anti-cheat saga. Riot’s anti-cheat team is crushing it.

Does Vanguard physically damage hardware?
No.
Does this impact hardware or software in any ways unrelated to Riot’s games?
No. The IOMMU security protection does not impact hardware, and would only impact the ability of players using DMA cheat devices to play our games.
Are normal players affected?
Players not using DMA cheat hardware are unaffected.
Why target DMA cheats?
DMA-based cheats are among the most sophisticated forms of cheating because they attempt to bypass traditional software detection by accessing memory directly through external hardware.
I’m affected by this. How do I fix it?
To continue cheating in other titles with this device, you may simply disable IOMMU in BIOS in the same place that you enabled it. Of course, you still won’t be able to play our games with these cheat devices enabled.
Why did Riot joke about “bricking” PCs?
We didn’t. The “paperweight” comment was about VALORANT cheat devices that no longer work in VALORANT. No hardware is being damaged and no other functionalities are impacted.

tar files -> rcs -> tar files -> svn -> sourcesafe -> svn -> git -> perforce -> git

fun fact: my career was svn (tortoise) -> git -> perforce -> git
My first year at netflix was a downgrade to perforce... I hated it.

Welp, concerns about the Canes being rusty can be put to bed. Let’s go Canes!

In a world where everyone can be a creator and AI does the heavy lifting, safety nets are more important than ever.
Our UI has had undo for destructive actions for a long time, now our APIs do too.
We're building more guardrails so you can operate at agentic speed, safely.

We're making it easy to debug and ship your applications on Railway using agents.
Today we shipped tools to make it even smoother
- Railway's Remote MCP
- Made Railway Agent available in the CLI

If they really wanted to improve the discourse here, @X would subtract engagement from ragebait posts from the creator payouts or not allow those people to participate at all.

The compute must flow.
Hiring to help us build data centers
We're building them at an absurd speed. Our compute footprint will likely 10x this year alone.
Designing racks, hardware, bill of materials, and getting it from "dollars to running compute" is insanely fun

People who are eager to take credit for the work of others have an unfair advantage versus those others who just don’t want to deal with drama.
Too many such cases on X lately.

Free CDN. No, seriously
