On the 11th of January 1982 twenty-two computer scientists met to discuss an issue with ‘computer mail’ (now known as email). Attendees included the guy who would create Sun Microsystems, the guy who made Zork, the NTP guy, and the guy who convinced the government to pay for Unix. The problem was simple: there were 455 hosts on the ARPANET and the situation was getting out of control. This issue w

Tetris is a classic time-waster, both in and outside of the office. What good is any computing device if it can’t play this game? Tokyo System House certainly thought so, and ported it to the NEC mini5 line of CP/M-based word processors. Let’s preserve it for future generations and then see what it’s like! I’ve been trying to get this game for a bit. First, I had been looking at the online old-gam

REST API Design Best Practices Handbook – How to Build a REST API with JavaScript, Node.js, and Express.js
I've created and consumed many API's over the past few years. During that time, I've come across good and bad practices and have experienced nasty situations when consuming and building API's. But there also have been great moments. There are helpful articles online which present many best practices, but many of them lack some practicality in my opinion. Knowing the theory with few examples is goo
How NAT traversal works
* can theoretically exist, but don't show up in the wild Once broken down like this, we can see that cone-ness isn’t terribly useful to us. The major distinction we care about is Symmetric versus anything else — in other words, we care about whether a NAT device is EIM or EDM. While it’s neat to know exactly how your firewall behaves, we don’t care from the point of view of writing NAT traversal c

Podcasting Setup 2020
It’s been a while since the last time I wrote about my podcasting setup (link in Japanese).

JavaScript is famous for the number of frameworks and tools that are created around it every week, and React, being one of the most popular of those frameworks as of late, “suffers” a similar fate, causing new developers to get overwhelmed when they attempt to start delving into the technology. So when it comes to picking the right IDE, the right visualizer or even the right stylesheet for your ne
共感にあらがえ - 内田樹の研究室を読んで これは、いろいろと考えさせられるいい文章だと思った。永井陽右という青年を振り回すかのように語る内田樹。こういうマウントは嫌いじゃない。 ただ、内田が、 「感情の器」って、あくまでも個人的な身体条件のようなものだから。 というとき、何か逃げた回答のような印象を受けた。 たとえそれが自分の中から湧き出す内発的なものだとしても、大昔にアダム・スミスが道徳感情論で追求したように、何かのテコで共鳴し、社会の規範を構成するに至るメカニズムが何かしらあるんだろうと俺には思えてならない。 そういう感覚を身に着けるのにどうすればいいかと問うた永井氏に、家風だとか、弟子入りだとか、そんな表現を内田氏がするのは、けむに巻いているようにしか思えなかった。 家風にしても弟子入りにしても、そのつながり方が、社会規範にむすびつくメカニズムがあるはずだ。 アレックス・カーが20

Python as a language is comparatively simple. And I believe, that you can learn quite a lot about Python and its features, just by learning what all of its builtins are, and what they do.
