Eugene Roshal built WinRAR and largely stayed out of the spotlight.
RAR stands for Roshal Archive.
He avoided Silicon Valley, skipped media attention, and kept his personal life private.
WinRAR became one of the most installed software tools in the world. The 40-day trial became a running joke since it never truly locked users out.
Estimated net worth ranges between $100M and $250M.
While others chased headlines, he built a compression algorithm that powered millions of PCs.

A new library called ownyourcode helps users study the code Claude Code generates instead of just copying it.
It turns the assistant into more of a mentor, with regular check-in tasks to test understanding while you work.
AI coding tools are starting to ship “learning mode” add-ons.

This is just a Windows 95 guide… hosted by a bikini model.
Back in the 90s, Microsoft actually released a whole series called “Sexy Software Presents: Learning Windows ’95 with Greta,” hosted by a real bikini model named Greta.
Now compare that with today’s software tutorials.

Instead of spending hours rewriting notes by hand, you can use ChatGPT to generate clean content and turn it into realistic handwritten-style study pages.
Paste your messy notes or textbook text into ChatGPT and prompt:
Turn this into clear, concise study notes for exams.You’ll get structured, simplified notes.
Paste the cleaned notes back into ChatGPT and prompt something like:
Create handwritten study notes on [topic]. Use student handwriting on lined paper. Add yellow highlights for key terms, red circles for dates, and small doodles for explanations.ChatGPT can generate notes that look like they were written by hand.
Save the result as PDF for printing or PNG for sharing.
Clean notes, no hours of rewriting.
