๐ง Day 1 ยท Linux Fundamentals & Filesystem
Before you automate anything, you have to understand the machine you're standing on.
How Linux is actually built - 4 layers:
Hardware โ Kernel โ Shell โ User Programs
The kernel talks to hardware. The shell (Bash) is how you talk to the kernel. Master that conversation and the rest of DevOps opens up.
Distros aren't different operating systems - same kernel, different packaging:
โ Debian family (Ubuntu, Debian) โ apt
โ Red Hat family (RHEL, CentOS, Fedora) โ yum/dnf
Learn the filesystem map - you'll live in it daily:
/etc = configs ยท
/var = logs ยท
/home = users ยท
/bin = essential commands ยท
/proc = live kernel info
And the rule that explains everything: in Linux, everything is a file - even devices and processes.
Your first 4 commands to run right now:
pwd # where am I?
ls -lah # list files (long, all, human sizes)
cd /var/log
whoami # which user am I?
โ ๏ธ One trap to remember:
/ is the root of the tree.
/root is the root user's home. Don't confuse them.
That's Day 1. You now understand the structure.
Tomorrow we move fast through essential commands & navigation.
Save this. Day 2 drops tomorrow. ๐
Web applications optimize every business operation, and they are still one of the most common paths attackers use to break in. To fix a flaw, you need structure:

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.
The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.
Access to all other Claude models is not affected.
We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

Introducing 30 days of AI.
For the next 30 weekdays, Iโm going to share one observation per day from the frontlines of AI.
I have the privilege of co-running an enterprise AI transformation firm, where I experience the edges of this technology, see the biggest challenges the biggest companies are facing, and have deep relationships with companies on the frontier (Anthropic, OpenAI, Lovable, Cursor, Perplexity, Vercel).
I get to live in the future for free, and I want to bring that future to those trying to disrupt themselves before they get disrupted.
Thereโs just two rules:
1) Each observation is actionable & understandable to the non-technical leader.
2) I canโt miss a day.
Post 1 coming soon.
