<strong>From key sprawl to scalable control: Rethinking SSH access (5 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Static SSH keys create security and operational challenges at scale due to long lifetimes, sharing, and lack of auditability, while SSH certificates provide short-lived, signed access controlled by a certificate authority. HashiCorp Vault and Boundary streamline SSH certificate management by dynamically generating and injecting ephemeral credentials, enabling secure, auditable, and scalable SSH access with centralized policy and minimal user overhead.

<strong>Improving the trustworthiness of JavaScript on the Web (20 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Web Application Integrity, Consistency, and Transparency (WAICT), a W3C-backed effort, aims to bring stronger security to the web by providing integrity, consistency, and transparency for web applications using in-browser JavaScript cryptography. The system uses subresource integrity (SRI) and integrity manifests to ensure that the code a user receives matches the code on record, addressing the vulnerability of JavaScript cryptography to malicious modification. To maintain the append-only nature of the chain, a trusted third party, called a witness, verifies hash chain consistency, signs the new chain hash with a timestamp, and adds it to a prefix tree that maps site domains to log chain hashes, creating a transparency preload list for client browsers.

<strong>Branching in a Sapling Monorepo (7 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Meta has open-sourced its Sapling source control system, designed for scalable monorepo branching, along with insights from its implementation. Two key workflows, non-mergeable full-repo branching using sl bookmark and mergeable directory branching through commands like sl subtree, solve branching challenges for Meta's diverse products. To address the limitations of full-repo branching and improve code management, Sapling introduces directory branching, which allows treating monorepo directories like traditional repository branches with linear commits.
