Utrecht (city)

Posted on by

.

Utrecht is host to Utrecht University, the largest university of the Netherlands, as well as several other institutes for higher education. Due to its central position within the country it is an important transportation hub (rail and road) in the Netherlands. It has the second highest number of cultural events in the Netherlands, after Amsterdam.

In Utrecht 52% of the population is female, 48% is male. Utrecht has a young population, with many inhabitants in the age category from 20 and 30 years, due to the presence of a large university.

Philosophy

Posted on by

.

What philosophy books would you recommend?

I can’t think of any I’d recommend. What I learned from trying to study philosophy is that the place to look is in other fields. If you understand math or history or aeronautical engineering very well, the most abstract of the things you know are what philosophy is supposed to be teaching. Books on philosophy per se are either highly technical stuff that doesn’t matter much, or vague concatenations of abstractions their own authors didn’t fully understand (e.g. Hegel).

Nerd 3

Posted on by

.

As a thirteen-year-old kid, I didn’t have much more experience of the world than what I saw immediately around me. The warped little world we lived in was, I thought, the world. The world seemed cruel and boring, and I’m not sure which was worse.

Because I didn’t fit into this world, I thought that something must be wrong with me. I didn’t realize that the reason we nerds didn’t fit in was that in some ways we were a step ahead. We were already thinking about the kind of things that matter in the real world, instead of spending all our time playing an exacting but mostly pointless game like the others.

Product

Posted on by

I think the solution is to assume that anything you’ve made is far short of what it could be. Force yourself, as a sort of intellectual exercise, to keep thinking of improvements. Ok, sure, what you have is perfect. But if you had to change something, what would it be?

If your product seems finished, there are two possible explanations: (a) it is finished, or (b) you lack imagination. Experience suggests (b) is a thousand times more likely.

The way to get an academic position is to write great books, proving your academic competence. But you may not want an university-academic life.

The way to get an academic position is not to get a PhD first, but to write great books, proving your academic competence. But you may not want an university-academic life.

Hacker ethic

Hacker 4

.

.

* Access to computers — and anything which might teach you something about the way the world works — should be unlimited and total. Always yield to the Hands-On Imperative!

* All information should be free.

* Mistrust authority — promote decentralization.

* Hackers should be judged by their hacking, not criteria such as degrees, age, race, sex, or position.

* You can create art and beauty on a computer.

* Computers can change your life for the better.

… free and open source software allows hackers to access the code used to create the software to improve or reuse it. In effect the free and open source software movements embody all of the hacker ethics.

[10] Hacker here means a highly skilled programmer, not a computer criminal. — Me

The basic difference is this: hackers build things, crackers break them. — Eric S. Raymond

“In academia, a “hacker” is a person who follows a spirit of playful cleverness and enjoys programming.”

Hacker 3

The Jargon File has had a special role in acculturating hackers since its origins in the early 1970s. Many textbooks and some literary works shaped the academic hacker subculture; among the most influential are:

* Hackers: Heroes of the Computer Revolution, by Steven Levy
* Godel, Escher, Bach, by Douglas Hofstadter
* The Art of Computer Programming (TAOCP), by Donald Knuth
* The Mythical Man-Month, by Brooks
* Compilers: Principles, Techniques, and Tools (“the Dragon Book”), by Aho, Sethi, and Ullman
* Structure and Interpretation of Computer Programs (SICP), by Abelson and Sussman
* The C Programming Language (K&R), by Kernighan and Ritchie
* The Hitchhiker’s Guide to the Galaxy, by Douglas Adams
* The Tao of Programming, by Geoffrey James
* The Illuminatus! Trilogy, by Robert Shea and Robert Anton Wilson
* Principia Discordia, by Greg Hill and Kerry Thornley
* The Soul of a New Machine, by Tracy Kidder
* The Cuckoo’s Egg, by Cliff Stoll
* The Unix System, by Stephen R. Bourne
* Hackers & Painters, by Paul Graham
* The Cathedral and the Bazaar, by Eric S. Raymond
* The essays of Richard M. Stallman (many published in Free Software, Free Society: Select Essays of Richard M. Stallman)

Hacker 2

.

* Creating software and sharing it with each other
* Placing a high value on freedom of inquiry; hostility to secrecy
* Information-sharing as both an ideal and a practical strategy
* Upholding the right to fork
* Emphasis on rationality
* Distaste for authority
* Playful cleverness, taking the serious humorously and their humor seriously

The difference between hackers and crackers, according to them, is that where hackers use their skills and knowledge to learn more about how systems and networks work, crackers will use the same skills to author harmful software (like viruses, trojans, etc.) and illegally infiltrate secure systems with the intention of doing harm to the system.

「hacker」們建設，而「cracker」們破壞。

真實的黑客所指主要指的是高級程式員，… 而不是為人所誤解專指對電腦系統及程式進行惡意攻擊及破壞的人。

Creative people are often considered eccentric.
Everyone is creative and eccentric.
We are all unique.
But the vast majority are afraid to let it out.
It’s more accurate to describe so-called creative,
eccentric people as simply less inhibited.

Design and Research

Posted on by

.

The difference between design and research seems to be a question of new versus good. Design doesn’t have to be new, but it has to be good. Research doesn’t have to be good, but it has to be new. I think these two paths converge at the top: the best design surpasses its predecessors by using new ideas, and the best research solves problems that are not only new, but actually worth solving. So ultimately we’re aiming for the same destination, just approaching it from different directions.

— Paul Graham
