Really, really bad week for Railway
Wasn't going to originally post this but since you charged us anyway after a 3 day outage @Railway is this how you teach your customer support people to talk to customers?

If you’re still running Ubuntu VMs, do yourself a favor and switch to Debian
What a disaster atlasum.net/blog/cve-2026-98…

If you’re not running an agent swarm that patches CVEs before they end up blowing up on X, you’re not doing it right
Hard to overstate how big of a deal this is.
tl;dr — ANY unpatched Linux server with even a single TCP port exposed to the internet (say for HTTP or SSH) and MPTCP active (default for many Go web servers) is vulnerable to complete takeover.

Reddit couldn’t die soon enough. The internet will be a better place without it
The collapse of Reddit will be studied.
After reporting earnings, its stock collapsed 30% in a single day.
It's down 44% in 2 weeks.
But the most important detail is what was revealed in that earnings call.
The CEO said AI is killing Google search.
People no longer get sent to Reddit from Google. They merely get their answers from the AI Mode itself.
Even Google confirmed this themselves with their disastrous results - AI mode is cannibalising their search business.
Pretty soon, no one will visit Reddit voluntarily. Its traffic will continue to crater.
The worst part?
Reddit isn't alone. There are millions of companies and publishers that rely on search traffic.
That's what happens when you rely on a single funnel for discovery.

If Claude is stealing your thunder and burning your tokens to give itself a byline on every commit, add this to ~/.claude/settings.json. Take back the credit you deserve, and let git blame point at the right person again

Who’s in charge of icon design at Ant?
We’re renaming our Max plans:
Max 5x → Max
Max 20x → Ultra
Max is still $100/month, and Ultra is still $200. If you’re a subscriber, there’s nothing you need to do.
We’re also removing the 5-hour limit for verified Ultra accounts, starting today with most existing subscribers. Newer accounts keep a temporary limit until they’re verified, which helps us prevent fraud and abuse. You'll get an email when it's removed.
Weekly limits remain unchanged. View our plans here: claude.com/pricing

PSA: if your older M series Mac is pegged at 100% CPU and deep into swap when running parallel agents, turn off Apple "Intelligence". ANECompilerService alone was casually compiling models at 95% CPU

No, coding interviews are not dead. If anything, the bar for understanding code just went up. When everyone can generate code for free, the real signal moves to comprehension, deep system reasoning, knowing why something works (or breaks), and yes - taste
The coding interview is dead, at least for my team at Anthropic. I've seen enough to know that it no longer provides signal. I removed it from loops this month.
I have a spicy, optimistic take - I think there's an opportunity for junior engineers: felixrieseberg.com/hunger-be…

eMudhra’s encryption keys were literally 4. CBSE’s exam portal left a god mode key in public JS.
The common thread here is these are Indian “tech” companies patronized by the govt with software and security practices that would embarrass the industry - you don’t need Mythos here
TL;DR of this week.
Your aunt’s password: “P4ssword!” (on a Post-it note in the kitchen)
The stewards and guardians of the internet’s encryption’s password: “4”
Yes, just 4. This key could be used to target and decrypt ~everything, and we’re still cleaning up residual risk.

If there were ever an announcement that made you want to never buy a product - this is it
Excited about our new Bee devices launching today. They turn your conversations into summaries, to-dos, and reminders, so the details are there when you need them.
Bee Frontier goes on your wrist or clips to your clothing, and Bee Eclipse snaps to the back of your phone to catch what you'd otherwise forget throughout your day, whether it's notes from a class you're taking, the details of a trip you're planning, or an idea that comes to you in the car.
They connect to Alexa+ and Amazon.com, so the things you mention are easy to find later. And you're always in control…one button turns it on or off, a light shows when it's on, audio is never stored, and only you can see your data.
Think folks are gonna find this really handy. aboutamazon.com/news/devices…

This might be the last year we can have a No Agent November. Just you, your IDE, Stack Overflow, and the slow realization that you don’t actually know how to code anymore

We missed it in person, but our neighbors and cameras caught this incredible SpaceX Falcon 9 jellyfish from our backyard 🤯
