Computer Scienceの学位を取るために学費無料のオンライン大学UoPeopleに入ってもうすぐ1年 - えんぴつぶろぐ
この記事は社会人学生 Advent Calendar 2020 7日目の記事です。 米国のオンライン大学University of the People（以下、UoPeople）に入って約1年経った振り返り記事となります。 これまでのUoPeople関連の記事はこちら 自分について University of the Peopleとは 動機 入学するには 授業について 卒業までの所要期間 Computer Science専攻はどんなコースが受けられるのか これまでの進捗 これまでにかかった金額 課題がめっちゃ出る どうやって勉強時間を確保しているか よかったところ 学習内容への満足度は高い 英語のライティングスキルは多分あがった 日英両方でインプットするメリット 毎日強制的にアウトプットできる。 GPAのためなら頑張れる よくなかったところ National Accreditationなの
はじめにこの記事は、放送大学の（主に情報コースを中心とする）学生さん向けに、私の履修済み科目の感想と主観的評価を共有して、履修計画の参考にしていただくことを目的に作成しました。下記の記事の通り、2019年-2020年の2年間で情報コースの科目を8割方履修したのでそれなりの網羅性があるかと思います。 （2023年2月追記）その後、選科履修生として履修した他コースの科目や大学院科目などを追加して112科目掲載しています。試験難易度については履修時期によって会場試験・在宅ペーパー試験・在宅Web試験が混在しているので参考程度でお願いします。 タイトルは私が現役生の時に通っていた大学の似たような評価システムから拝借しました。 以下の科目は基本的にナンバリングが低い順に並べています。閉講済みの科目も混じっていますが、記録と後継科目の参考のために残しておきます。あくまで全て（上記の記事にある通り、文系

転置インデックスの圧縮技法
転置インデックスは、検索エンジンの実装において、中心的な役割を果たすデータ構造である。 転置インデックスのデータ構造とアルゴリズムは、クエリ処理アルゴリズムとともに、検索エンジンの性能に直結する。とくに大規模な検索エンジンにおいては、キャッシュ効率を高めてクエリ処理を高速化するために、転置インデックスの圧縮は必要不可欠となっている。 この記事では、転置インデックス、とくにポスティングリストの圧縮について、近年の手法を簡単にまとめる。 目次 転置インデックスの基本 転置インデックスのデータ構造と特性 転置インデックスのアクセスパターン 近年のインデックス圧縮技法 Variable-Byte Family VByte Varint-GB Varint-G8IU Masked-VByte Stream-VByte Opt-VByte Simple Family Simple9 Simple16
The end of classical computer science is coming, and most of us are dinosaurs waiting for the meteor to hit. I came of age in the 1980s, programming personal computers such as the Commodore VIC-20 and Apple ][e at home. Going on to study computer science (CS) in college and ultimately getting a Ph.D. at Berkeley, the bulk of my professional training was rooted in what I will call “classical” CS: p

In an interview with Evrone, Ryan Dahl speaks about the main challenges in Deno, the future of JavaScript and TypeScript, and tells how he would have changed his approach to Node.js if he could travel back in time. We met with Ryan Dahl, the creator of Node.js, to discuss the origins of the platform, its impact on JavaScript, and his thoughts on its future. In the interview he also reflected on hi
Understanding inheritance and other limitations in Rust - LogRocket Blog
Editor’s note: This Rust guide was updated on 3 Aug, 2022 to include information about doubly linked lists and borrowing things that aren’t static in async code. As a moderator of the Rust subreddit, I regularly happen upon posts about developers’ attempts to transpose their respective language paradigms to Rust, with mixed results and varying degrees of success.

Preparing for the Systems Design and Coding Interview
At Big Tech and high-growth startups, coding and systems design interviews are common - and fairly standard. A lot of people have asked me for preparation advice for these. Here is what I used when getting ready for an E5/E6 Facebook interview, and the one at Uber - where I was hired as a senior software engineer (L5). It's the same resources I recommend to people who are preparing for Big Tech or
Over the course of my Spring 2020 semester at Harvey Mudd College, I developed a self-hosting compiler entirely from scratch. This article walks through many interesting parts of the project. It’s laid out so you can just read from beginning to end, but if you’re more interested in a particular topic, feel free to jump there. Or, take a look at the project on GitHub.

CRDTs go brrr
5000x faster CRDTs: An Adventure in Optimization July 31 2021 A few years ago I was really bothered by an academic paper. Some researchers in France put together a comparison showing lots of ways you could implement realtime collaborative editing (like Google Docs). They implemented lots of algorithms - CRDTs and OT algorithms and stuff. And they benchmarked them all to see how they perform. (Cool
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
文系学部卒でも無条件で不合格にならないアメリカのオンラインコンピューターサイエンス修士コースを調べ、出願校を決めた｜Toshinori Sugita
出願校最初の出願校は、ジョージア工科大学のOMSCSになりそうだ。履修できる授業の種類、オンラインコースの懐の深さ（合格率の高さ）（、費用）が主な理由だ。 前回の記事を書いた時点では、ペンシルバニア大学のMCITがベストではないかと考えていた。 しかし、他の選択肢を十分検討していなかったので、候補になり得るコースをリストアップして比較した。特に気にしたのは、つぎの点だ。 ・文系学士が無条件でNGにならない ・CS推奨であっても、テストやMOOCs受講、業務経験などでなんとかなる ・アメリカ（最初の候補として。イギリスやオーストラリアがダメというわけでは全然ないが、英語で学ぶことを前提としたい） ・授業（基礎、分散システム、その他機械学習、データサイエンスなど共通理解になり得るものが選択できる） ・出願要件の具体的な数字（英語テスト、書類、出願期限） ・合格率（オンラインはオンキャンパスと比
Statically typed programming languages can help catch mismatches between the kinds of values a program is intended to manipulate, and the values it actually manipulates. While there have been many bytes spent on discussions of whether this is worth the effort, some programming language designers believe that the type checking in current languages does not go far enough.

Manuel Cerón
Last year I finally decided to learn some Rust. The official book by Steve Klabnik and Carol Nichols is excellent, but even after reading it and working on some small code exercises, I felt that I needed more to really understand the language. I wanted to work on a small project to get some hands-on experience, but most of my ideas didn’t feel very well suited for Rust. Then I started reading the
I’m a fairly frequent Hacker News lurker, especially when I have some other important task that I’m avoiding. I normally head to the Active page (lots of comments, good for procrastination) and pick a nice long discussion thread to browse. So over time I’ve ended up with a good sense of what topics come up a lot. “The Bay Area is too expensive.” “There are too many JavaScript frameworks.” “Bootcam

Functors and Monads For People Who Have Read Too Many "Tutorials" - iRi
Celebrating Over 10 Years Of Being Too Lazy To Pick A Tagline Title is literally true. This may not be the best place to learn about these concepts for the first time, because I'm going to focus on knocking down the misconceptions about them. Then again, it may not be the worst place, for the same reason. I had promised myself I would not add to the pile of functor or monad "tutorials", but I've b

The Alkyne GC · mcyoung
Alkyne is a scripting language I built a couple of years ago for generating configuration blobs. Its interpreter is a naive AST walker1 that uses ARC2 for memory management, so it’s pretty slow, and I’ve been gradually writing a new evaluation engine for it. This post isn’t about Alkyne itself, that’s for another day. For now, I’d like to write down some notes for the GC I wrote3 for it, and more

As computer systems get more sophisticated we've seen a growing trend to value deep specialists. But we've found that our most effective colleagues have a skill in spanning many specialties. We are thus starting to explicitly recognize this as a first-class skill of “Expert Generalist”. We can identify the key characteristics of people with this skill - and thus recruit and promote based on it. We

Data structures and algorithms study cheatsheets for coding interviews | Tech Interview Handbook
General interview tipsClarify any assumptions you made subconsciously. Many questions are under-specified on purpose. Always validate input first. Check for invalid/empty/negative/different type input. Never assume you are given the valid parameters. Alternatively, clarify with the interviewer whether you can assume valid input (usually yes), which can save you time from writing code that does in

While this post is addressed to F# .NET developers, it introduces much wider concepts starting from hardware architecture to overall .NET runtime and JIT compiler optimizations. It shouldn't be a surprise - optimizing the application performance requires us to understand the relationships between our high level code and what actually happens on the hardware. There's a popular opinion that F# code
C++ safety, in context
Scope. To talk about C++’s current safety problems and solutions well, I need to include the context of the broad landscape of security and safety threats facing all software. I chair the ISO C++ standards committee and I work for Microsoft, but these are my personal opinions and I hope they will invite more dialog across programming language and security communities. Acknowledgments. Many thanks
