I remember learning about it from Redis: https://redis.io/docs/data-types/hyperloglogs/

I used Borland Delphi (as well as C++ Builder for some period) throughout my university times for all kinds of home works and hobby apps. It was extremely easy to build simple but still good-looking UIs. At some point I even had a small reusable library for graph problems (add/edit nodes/edges with nice arrows/labels etc.) What I really liked was how fast you could get to real coding part with minimum boilerplate. Happy to see Lazarus IDE still having a strong community.

That's a very good question.

Given how old is Turing's paper and how much it was 'dissected' for the book, I would ask the following: * Any other top papers that inspired Charles (or he found them worthy of serious deep dive)? * Does he still read modern papers?

The latter is particularly interesting. I don't have academic background, but some of the people I spoke to claimed that there's lots of subpar papers produced nowadays. Obviously, amount produced in every field significantly increased lately, so it would be interesting to learn how someone with decades of experience is able to filter that out.

Sounds amazing. Big fan of his writing style, have two of his books: "Code" and "The Annotated Turing".

I'd be curious to learn about his work habits - have they changed over the years? Has he experienced any procrastination during his career and how he dealt with it? Any advice to those who got bored by the challenges of the modern software industry?

Only now I found that he has a blog, so it looks like I've got some new reading material: https://www.charlespetzold.com/blog/toc.html

The opposite is adding space before the command. The command will run but it will not be saved in history.

EDIT: This apparently needs to be configured - setting HISTCONTROL=ignorespace

That's a nice and very extensive collection.

As a follow-up, I can also recommend Effective Shell series. I used to have navigation shortcut diagram from Part 1 (https://dwmkerr.com/effective-shell-part-1-navigating-the-co...) printed out.

There's Lazarus project (https://www.lazarus-ide.org/) - which is a Delphi compatible IDE. I've used it once to build a simple UI app, and it was a real nostalgic look back in time. Not to mention that it was extremely simple to build the app.

Norton Commander - https://en.wikipedia.org/wiki/Norton_Commander. Not sure how elegant on the inside, but it comes from the era when software development was not so fast paced. And the fact that it inspired so many spin-offs (just to mention few that I personally used: Volkov Commander, Midnight Commander, FAR Manager, and my favourite - DOS Navigator (it had spreadsheet!)).

Just found this one (didn't know it exists!): https://traintimes.org.uk/map/tube/

There's another amazing instant classic book by Charles Petzold - "The Annotated Turing".
