Omarchy now natively supports your Mac!
The installer offers plug-n-play dual boot installation, and Omarchy supports everything you need, including external monitors, battery info + limits, trackpad, GPU, wireless comms, TouchID, and much more.
This is the most advanced Linux distribution on Apple Silicon.
It starts with M1/M2/M3/Neo support, with more models coming soon.
We can fix everything.
Omarchy 4.5 is finally here! Traditional desktop mode, M1/M2/M3/Neo compatibility, 50 languages, 7-second installs, and a million other features, fixes, and improvements. omarchy.org/news/2026/11/oma…

Omarchy 4.5 will ship with full compatibility for M1, M2, M3, and Neo! Incredible achievement from the Omarchy M team. The installer makes this so smooth, the dual boot makes it a no brainer. Apple hardware liberated. M4-6 on the way. WE CAN FIX EVERYTHING!

When I set up a new Hetzner VPS first thing I do install Tailscale and once I'm in via Tailscale lock down the firewall to only accept web traffic on HTTPS 443 for Cloudflare IPs and SSH 22 for Tailscale IP
That way nobody can get in
I know I keep repeating this but it should be basics of setting up a new VPS
So basic IMHO it should be part of any VPS service to default install Tailscale and enable it so it's the only way to get in
Why?
A VPS server is just like your laptop or destop computer but now imagine if it's connected to the entire internet with 8 billion people that can access it and try hack it
You want to only have it accessible to you
And if you want to host a website on your VPS (like I do), you should only let Cloudflare access your VPS so it can stand in front and block any hack attempts
Never expose a VPS to the world wide web which realistically is the world WILD web
I created a redis instance on hetzner with public port open for few minutes and someone was running a cryptominer the next moment taking 50% CPU 💀
After that I always use @Tailscale 👌

The best line of code is the line not written
So basically, today PHP got two critical bugs that let anyone run code on your server without even logging in, which is bad, and then the details leaked before the patch was even out, which is worse, and it works on WordPress and MediaWiki and Magento and Joomla and Laravel, and Censys says like 1.5 million servers are running a version with no fix, so the NSA was like "take your system offline," and the FBI was like "take your system offline," and CISA and the UK and CERT-EU were all like "take your system offline," and then the Prime Minister of Japan, the actual Prime Minister, posted at 5:55 in the morning telling 48.8 million people to take their system offline, so everyone took their system offline, like the Dutch cybersecurity agency took its own website offline, and the Dutch parliament went offline, and the Port of Rotterdam went offline, and Finland and France and Denmark started pulling government sites, and Wikipedia went down, and Archive.org went down, and Asana and GOG and Something Awful went down, and the University of Vienna's webmail went down for some reason, and that's just PHP. Because GitLab also dropped a CVSS 10.0, which is the highest score they give out, for a bug that's been there since 2014, so that's every self-hosted GitLab for twelve years, and then LiteLLM 1.107.0 got hijacked and shipped a credential stealer and a remote access trojan in every single wheel and the Docker images, including latest, and you didn't even have to import it, just installing it was enough, and it's the second time this year, and then Railway paused every deployment on the entire platform because someone got into the environment variables, so now everyone has to rotate every secret they've ever stored there, and TiDB Cloud said someone was walking around inside with stolen credentials for basically a month and an extortion group says they took 10.6 terabytes, and Zeabur got breached for the second time in two months and is just shutting down, like the whole company, and Node.js patched remote code execution and a TLS bypass, and CISA says Plex is being actively exploited, and someone took over 300 Tor exit relays to steal SSH passwords, and SafePay ransomware has hit over 600 critical infrastructure orgs, and India's biggest bank filed a data loss incident, and Japan has been in an official state of emergency in cyberspace since October 9, which honestly explains the 5:55 AM post. Oh, and eMudhra, a certificate authority that's issued over 60 million certificates, whose entire job is proving websites are who they say they are, was supposed to be using private keys that are random numbers over a hundred digits long, and one of them was 4. Just 4. And the others were like 66 and 237. Anyway, it's Wednesday.

Here's a 45-second TL;DR on Jev.
I find the core idea beautifully simple, but the video made it really hard to understand.
Hope you find it helpful.
After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI?
I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev
• 20-200x faster
• 40-400x cheaper (w/ output tokens free)
• Frontier composable intelligence optimized for decisions
AFAICT the shortest path to AI-based economic revolution

The guy who helped invent ChatGPT just shipped an AI that refuses to talk.
No essays.
No poems.
No “as an AI language model.”
It only makes decisions.
200x faster.
400x cheaper.
Output tokens: free.
Hallucinations: impossible, because it can’t speak.
We spent 4 years paying a novelist to do an accountant’s job.

Omarchy makes for a great first computer! Kids don't have preconceived notions about operating systems. They can learn everything because they don't have to unlearn anything. They also like things that are COOL and FUN!

Some of the biggest companies of the next decade won't be software businesses. They'll be services companies like insurance carriers, law firms, and tax practices rebuilt from scratch with AI doing most of the work.
In this episode of Startup School, YC Visiting Partner @CharlieWarren walks through the playbook for building AI native services companies, covering how to pick a market with the right traits, why variance kills these businesses faster than anything else, and the P&L math that’ll transform your business model.

We did $500k in revenue within 2 months after realizing that customers don't want an AI platform.
None of our clients have seen our platform, nor do they care to.
They just want their problems solved quickly and to a high standard (doesn't matter if it's with AI or literally paper).
We built internal agents for regulatory work, and delivered them as a service for 10x the price…
Just own the outcome.

Coding is solved. I haven’t written a single line of code since 2025. But software engineering is more alive than ever. If you’re building something that matches a known pattern, AI will deliver perfection. But as soon as you get into deeply complex, novel work, it produces slop.

repetition is the bridge between who you are and who you want to be.
it's just the same boring rep, done when you don't feel like it, on the day nobody's watching, for longer than makes sense.

Sequoia's thesis: the next $1T company sells work🏗️, not software
Sell a copilot and you compete with every model release. Sell the outcome, books closed, contracts reviewed, claims handled, and every AI improvement widens your margin instead of threatening your product.
The insight most people miss: for every $1 spent on software, roughly $6 goes to services.
SaaS chased the software dollar. AI chases the services dollar at software margins.
Not AI for accountants. The AI accounting firm. Not AI for lawyers. The AI law firm
The winners will look like services firms rebuilt on software infrastructure, and most founders are still building copilots.
Which dollar are you chasing?

“Human wants and needs are endless.”—Milton Friedman
"Subscriptions and advertising were the business models of an internet designed for human attention. x402 is the first glimpse of what comes next. A web where software pays software for value, automatically, in the same HTTP request. It is the smartest infrastructure play of the last few years, and almost nobody has noticed yet. In five years time, I bet that will be different."
