先日、博士（情報学）になりました。学部と大学院をあわせた 9 年間で読んだ情報科学関連の教科書・専門書を思い出を振り返りつつここにまとめます。私は授業はあまり聞かずに独学するタイプだったので、ここに挙げた書籍を通読すれば、大学に通わなくてもおおよそ情報学博士ほどの知識は身につくものと思われます。ただし、特に大学院で重要となる論文を読み書きすることについては本稿には含めておりません。それらについては論文読みの日課についてや論文の書き方などを参考にしてください。 joisino.hatenablog.com 凡例：（半端）とは、数章だけ読んだ場合か、最後まで読んだものの理解が浅く、今となっては薄ぼんやりとしか覚えていないことを指します。☆は特におすすめなことを表します。 学部一年 寺田 文行『線形代数 増訂版』 黒田 成俊『微分積分』 河野 敬雄『確率概論』 東京大学教養学部統計学教室『統計学
Parse, don’t validate
Historically, I’ve struggled to find a concise, simple way to explain what it means to practice type-driven design. Too often, when someone asks me “How did you come up with this approach?” I find I can’t give them a satisfying answer. I know it didn’t just come to me in a vision—I have an iterative design process that doesn’t require plucking the “right” approach out of thin air—yet I haven’t bee

The Dangerous Populist Science of Yuval Noah Harari ❧ Current Affairs
Watch videos of Yuval Noah Harari, the author of the wildly successful book Sapiens: A Brief History of Humankind, and you will hear him being asked the most astonishing questions. “A hundred years from now, do you think we will still care about being happy?” — Canadian journalist Steve Paikin, on the “The Agenda with Steve Paikin” “What I do, is it still relevant, and how do I prepare for my futu
Excel has dominated the spreadsheet market since the 1990s, and it remains a powerful tool for data analysis. Unfortunately, its very power makes it incredibly dangerous even in the hands of experienced users — and how many employees can truly claim to have mastered the program’s complexities? If you use Excel expense-report templates in your business, it’s fatally easy for user error to creep int
The Development of the C Language* Dennis M. Ritchie Bell Labs/Lucent Technologies Murray Hill, NJ 07974 USA dmr@bell-labs.com ABSTRACT The C programming language was devised in the early 1970s as a system implementation language for the nascent Unix operating system. Derived from the typeless language BCPL, it evolved a type structure; created on a tiny machine as a tool to improve a meager progr
An in-depth guide to performance optimization with webpack - LogRocket Blog
These days, you have to use a module bundler like webpack to benefit from a development workflow that utilizes state-of-the-art performance optimization concepts. Module bundlers are built by brilliant people just to help you with these difficult tasks. In addition, I recommend using a starter kit or a modern boilerplate project with webpack configuration best practices already in place. Building
Bash Pitfalls This page is a compilation of common mistakes made by bash users. Each example is flawed in some way. 1. for f in $(ls *.mp3) One of the most common mistakes BASH programmers make is to write a loop like this: for f in $(ls *.mp3); do # Wrong! some command $f # Wrong! done for f in $(ls) # Wrong! for f in `ls` # Wrong! for f in $(find . -type f) # Wrong! for f in `find . -type f` # W
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. And to back up that claim, I'll be doing just that. Just to be clear, this is not going to be a tutorial post. Covering such a vast amount of material in a single blog post, while starting from the beginning is p

Advancing Excel as a programming language with Andy Gordon and Simon Peyton Jones - Microsoft Research
Episode 120 | May 5, 2021 Today, people around the globe—from teachers to small-business owners to finance executives—use Microsoft Excel to make sense of the information that occupies their respective worlds, and whether they realize it or not, in doing so, they’re taking on the role of programmer. In this episode, Senior Principal Research Manager Andy Gordon, who leads the Calc Intelligence tea
Way back in 1992, just as the ‘Internet’ was starting to sound interesting, a company in the UK used technology to disrupt television. Rupert Murdoch’s Sky realised that you could buy football rights for far more than anyone had ever thought of paying before, and you could make your money back by selling the games on subscription instead of pay-per-view or advertising, and you would be able to del

Darkness of child abduction business｜Nozomi Makino | Hanadaプラス
When you return home tired after work, your children rush and say, "Welcome back!" Their small hands hold on to you tightly. You swear to do your best to take care of your dearest children. Such daily happiness is suddenly taken away. When you get home, no one is there. No furniture either. You find it completely empty. Such abductions of children have occurred a lot in this country. The one who a

During my final term at UWaterloo I took the CS444 compilers class with a project to write a compiler from a substantial subset of Java to x86, in teams of up to three people with a language of the group’s choice. This was a rare opportunity to compare implementations of large programs that all did the same thing, written by friends I knew were highly competent, and have a fairly pure opportunity

For good reasons, accordions are a popular UI element today: on mobile, they are an essential tool because they collapse content and make page length manageable, but even on desktop, they mitigate visual complexity and allow users to focus on the content mos
Since I was unable to travel for a couple of years during the pandemic, I decided to take my new-found time and really lean into Rust. After writing over 100k lines of Rust code, I think I am starting to get a feel for the language and like every cranky engineer I have developed opinions and because this is the Internet I’m going to share them. The reason I learned Rust was to flesh out parts of t

research!rsc: The Principles of Versioning in Go (Go & Versioning, Part 11)
This blog post is about how we added package versioning to Go, in the form of Go modules, and the reasons we made the choices we did. It is adapted and updated from a talk I gave at GopherCon Singapore in 2018. Why Versions? To start, let’s make sure we’re all on the same page, by taking a look at the ways the GOPATH-based go get breaks. Suppose we have a fresh Go installation and we want to write
Over the last year or so, I have found myself on a journey to deeply understand how to run Rails applications backed by SQLite performantly and resiliently. In that time, I have learned various lessons that I want to share with you all now. I want to walk through where the problems lie, why they exist, and how to resolve them. And to start, we have to start with the reality that… Unfortunately, ru
How Tadayuki Watanabe Disproved a Major Conjecture About Spheres | Quanta Magazine
In a burst of work, mathematicians have moved closer to understanding just how many ways there are of contorting a simple sphere so that, in the end, it still resembles itself. Much of the progress comes from results by Tadayuki Watanabe at Kyoto University. Over the last several years, he has figured out how to adapt a powerful technique for the broader purpose of studying spheres of any number o
If you combine this with the Unicode table, you’ll see that English is encoded with 1 byte, Cyrillic, Latin European languages, Hebrew and Arabic need 2, and Chinese, Japanese, Korean, other Asian languages, and Emoji need 3 or 4. A few important points here: First, UTF-8 is byte-compatible with ASCII. The code points 0..127, the former ASCII, are encoded with one byte, and it’s the same exact byt
GitHub - lovasoa/bad_json_parsers: Exposing problems in json parsers of several programming languages.
Many JSON parsers (and many parsers in general) use recursion to parse nested structures. This is very convenient while programming the parser, but it has consequences on what the parser can parse: indeed, the size of the call stack is usually limited to a value several orders of magnitude smaller than the available RAM, and this implies that a program with too many levels of recursion will fail.

Staff archetypes
Most career ladders define a single, uniform set of expectations for Staff engineers operating within the company. Everyone benefits from clear role expectations, but career ladders are a tool that applies better against populations than people. This is particularly true for Staff-plus engineers, whose career ladders often paper over several distinct roles hidden behind a single moniker. The more
What I Worked On
February 2021 Before college the two main things I worked on, outside of school, were writing and programming. I didn't write essays. I wrote what beginning writers were supposed to write then, and probably still are: short stories. My stories were awful. They had hardly any plot, just characters with strong feelings, which I imagined made them deep. The first programs I tried writing were on the
Go 1.20 Cryptography
The first second release candidate of Go 1.20 is out![1] This is the first release I participated in as an independent maintainer, after leaving Google to become a professional Open Source maintainer. (By the way, that’s going great, and I’m going to write more about it here soon!) I’m pretty happy with the work that’s landing in it. There are both exciting new APIs, and invisible deep backend imp
tl;dr: Use MessagePack, rather than CBOR. Introduction I recently wanted to choose a binary encoding. This was for a project using Rust serde, so I looked at the list of formats there. I ended up reading about CBOR and MessagePack. Both of these are binary formats for a JSON-like data model. Both of them are "schemaless", meaning you can decode them without knowing the structure.

As the 2010’s draw to a close, it’s worth taking a look back at the monumental progress that has been made in Deep Learning in this decade.[1] Driven by the development of ever-more powerful compute and the increased availability of big data, Deep Learning has successfully tackled many previously intractable problems, especially in Computer Vision and Natural Language Processing. Deep Learning has
How to Do Great Work
July 2023 If you collected lists of techniques for doing great work in a lot of different fields, what would the intersection look like? I decided to find out by making it. Partly my goal was to create a guide that could be used by someone working in any field. But I was also curious about the shape of the intersection. And one thing this exercise shows is that it does have a definite shape; it's
Why the Past 10 Years of American Life Have Been Uniquely Stupid
The story of Babel is the best metaphor I have found for what happened to America in the 2010s, and for the fractured country we now inhabit. Something went terribly wrong, very suddenly. We are disoriented, unable to speak the same language or recognize the same truth. We are cut off from one another and from the past. It’s been clear for quite a while now that red America and blue America are be
