a professor at Illinois got frustrated with existing systems programming textbooks
so he started a wikibook project and had students help write it
it covers C, processes, threads, synchronization, memory allocation, networking, filesystems, scheduling and security
all in one free PDF
it eventually became the official textbook for CS 241 at UIUC with more than 1000 students taking the course every year
written for people who already know how to code and want to understand what actually happens underneath
Uber stopped hiring to save money.
By April they'd blown the entire AI budget anyway.
5,000 engineers on Claude Code.
Up to $2,000 a month. Each.
Now the COO can't tell if any of it worked.
A salary is a number you control.
Tokens are a number that never stops.
They didn't cut the cost.
They rented it from Anthropic - forever.
MICROSOFT CANCELED CLAUDE CODE!
IT COST TOO MUCH.
Major tech companies are confronting the steep reality of AI inference costs as the era of heavy subsidies appears to be ending.
Microsoft is canceling most internal licenses for Anthropic’s popular Claude Code tool by June 30, 2026 less than six months after rolling it out broadly to engineers primarily due to escalating token-based expenses, while shifting teams toward its own GitHub Copilot CLI.
This mirrors broader pressures: Uber’s CTO revealed the company had already exhausted its entire 2026 AI budget in just four months thanks to heavy Claude usage among thousands of engineers (with individual monthly costs often hitting $500–$2,000), and GitHub is transitioning Copilot to usage-based billing with higher per-token rates starting June 1st.
The reality is good enough AI will expand and constantly get better removing the oxygen of the most expensive.
@md_kasif_uddin Well that is a wrong question to ask....all of them solves different problem, they are different models of DBs. So choose the best DB for you task at hand. So always consult the problem domain.
