The Elements of Typographic Style

Marton Trencseni - Sat 23 July 2022 • Tagged with book, typography

The Elements of Typographic Style by Robert Bringhurst is the most beautiful book I've ever held in my hand. This stunning piece of readable art shows Bringhurst's love for the craft of design, typography and writing, and his mastery of these subject, a result of his life-long devotion to them. I am not a professional typographer, but I enjoyed glancing at, reading and appreciating every page of this book.

The Culture Map

Marton Trencseni - Fri 22 July 2022 • Tagged with book, management, culture

The Culture Map by Erin Meyer is a system of 8 scales which can be used to determine how cultures vary along a spectrum. The scales can be used to analyse one culture relative to another and decode how culture influences your international collaborations. I find the considerations in the book helpful irrespective of cultural background; the 8 scales can be applied to individuals as well, irrespective of where they are from.

Amazon established a set of principles and mechanisms, enabling the company to grow from a single founder to several hundred thousand employees while remaining stubbornly true to its mission of obsessing over customers to create long-term shareholder value.

HBR Guide to Better Business Writing

Marton Trencseni - Fri 08 July 2022 • Tagged with hbr, book, management, writing

If your writing is sloppy and artless people will think you are the same. They won’t care about your message, they won’t do business with you. It’s not true that only ideas matter. Good writing gets ideas noticed.

Culture Docs: Facebook, Netflix and Valve

Marton Trencseni - Sat 18 June 2022 • Tagged with culture, facebook, netflix, valve

Many companies have some sort of "Culture Doc", a booklet or similar, which explains to new joiners what the company is about. I received Facebook's "Little Red Booklet" when I joined in 2016 February, and I was amazed how good it was. Recently I was researching other companies' Culture Docs, and found a version of Netflix's and Valve's online. It's interesting to compare and contrast what these different companies choose to put in their Culture Doc. Facebook's Culture Doc is very mission and execution oriented and serious, Netflix is analytical and HR-focused, and Valve's is a lighthearted explanation of how the company works.

"Over 70% of all Porsche vehicles ever built are still on the road today"

Porsche proudly advertises "Over 70% of all Porsche vehicles ever built are still on the road today". Is this a testament of the quality and longevity of Porsche cars, or simply a result of the brand switching from niche sportscar manufacturing to mass production around the year 1999?

Solving 5 algorithmic interview questions

Marton Trencseni - Sat 26 March 2022 • Tagged with interview, python

Recently I was considering whether to introduce some CS style algorithmic interview questions into our Data Science hiring loop, since having an understanding of algorithms and data structures can be useful for Data Scientists. Not having done this soft of interview for a few years I picked up my copy of Daily Coding Problem and starting solving a few problems to refresh my feeling for what it feels like as a candidate, and whether it would give us any useful signals.
