お知らせ：外資や日本のトップ企業の面接対策に興味のある方はぜひ furustack.com ! ジョブレベル呼び方は組織によって違うが一般的にジョブレベルは ジュニア（新卒・インターンなど） ミッド シニア スタッフ -> シニアスタッフなど/マネージャ -> シニアマネージャ のように分けられてます。 実例を見るとwiseはこのようにキャリアマップを作っています wiseエンジニアのキャリアマップシニアに到達するとその次はICのトラック（スタフ、プリンシパル）を続けるかピープルマネジメントトラック（エンジニアリングリード、シニアエンジニアリングリード、ディレクター）に移すか選択できる。もちろんシニアのままにいるのも企業によって可能だったりします。シニアエンジニアは１人前でタスクをこなせたりプロジェクトをリードしたりできると期待されているでしょう。チームメイトのメンターシップも必要があれば
インターネットやAIを駆使しながら、領域に捉われずにさらなる挑戦を行うDeNAの取り組みを紹介する「DeNA TechCon 2023」。ここで認証認可システムのリノベーションチームの岸直輝氏が登壇。Shift Leftの考え方を基に実践している静的解析や自動テスト、挙動の差分を自動で発見するための取り組みについて紹介します。全2回。後半は、各フェーズにおける、静的解析・ユニットテスト・E2Eテスト、それぞれの取り組みについて。前回はこちら。 静的解析のメリットとデメリット岸直輝氏：では、ここからは今お話ししたShift Leftの具体的な取り組みについて見ていきましょう。ここでは、各フェーズごとに対応する取り組みを、静的解析、ユニットテスト、E2Eテストの3つに分けて紹介します。 まずは静的解析について。静的解析は、プログラムを実行することなく、静的にさまざまな異常を検出する手法です。静
I want to write a post about Pitchfork, explaining where it comes from, why it is like it is, and how I see its future. But before I can get to that, I think I need to share my mental model on a few things, in this case, Ruby’s GVL. For quite a long time, it has been said that Rails applications are mostly IO-bound, hence Ruby’s GVL isn’t that big of a deal and that has influenced the design of so
A professional programmer delivers value through the authoring and maintaining of software that solves problems. (There are other important ways for professional programmers to deliver value but this post is about programming.) Programmers rely on various tools to author software. Arguably the most important and consequential choice of tool is the programming language. In this post, I will articul
No matter what ranking system you look at, whether the TIOBE Index, the Popularity of Programming Language Index, RedMonk’s bi-annual language rankings, or GitHub’s yearly State of the Octoverse, Java has been sitting among the top three languages since shortly after its launch in 1995. To listen to the general scuttlebutt of the developer crowd over time, however, you might think that Java was in

Logback components written for logback 1.2 should work without change in version 1.3. However, Joran, logback's configuration system, has been rewritten to use an internal representation model which can be processed separately. Thus, code depending on Joran needs to be adapted to changes in Joran (logback's internal configuration mechanism). As a result of enhancements to Joran, logback configurat
ScalaTest
Using matchers ScalaTest provides a domain specific language (DSL) for expressing assertions in tests using the word should. Just mix in should.Matchers, like this: import org.scalatest.flatspec._ import org.scalatest.matchers.should._ class ExampleSpec extends AnyFlatSpec with Matchers { ... You can alternatively import the members of the trait, a technique particularly useful when you want to tr
01 june, 2024 most of rust discussions nowadays revolve around memory safety, and how it is safer than C / C++ / zig / go / whatever language is being trashed on twitter that day. while yes, that is true - not that the bar for most of these is particularly high - what I think is the main point of the language is always glossed over: correctness. when one tries to criticize any of the aforementione
Announcing Scala.js 1.4.0
Jan 12, 2021. We are excited to announce the release of Scala.js 1.4.0! This release complements the module splitting support, introduced in Scala.js 1.3.0, with support for dynamic module loading. It is now possible to structure an application such that specific features are only loaded if necessary, the first time they are used. In addition, this release significantly improves the performance of
Key InsightsRust is the first industry-supported programming language to overcome the longstanding trade-off between the safety guarantees of higher-level languages and the control over resource management provided by lower-level systems programming languages.It tackles this challenge using a strong type system based on the ideas of ownership and borrowing, which statically prohibits the mutation
Summary Enable JavaDoc documentation comments to be written in Markdown rather than solely in a mixture of HTML and JavaDoc @-tags. Goals Make API documentation comments easier to write and easier to read in source form by introducing the ability to use Markdown syntax in documentation comments, alongside HTML elements and JavaDoc tags. Do not adversely affect the interpretation of existing docume
