Developer tool sprawl is real. You've got one tab for logs, another for metrics, half a dozen for cloud services, and somewhere in there is the code you're actually trying to ship.

🫣 Stop playing hide-and-seek with your tools. Microsoft Azure brings together everything you need to build and run software in a single workspace.

Goodbye, hunting for the right dashboard. Hello, one unified view—and a faster path to innovation.

Although Unix systems are often described as treating everything as a file, many core functions like network connections and process identifiers typically rely on distinct system calls rather than standard file interfaces. A notable exception exists in Linux through the `/proc//mem` interface, which allows direct access to a process's address space using file-like semantics.

A critical vulnerability recently allowed unauthorized individuals to seize control of Instagram accounts by exploiting flaws in the platform's AI-driven support system. By faking a user's location and requesting a password reset through a support bot, attackers could redirect verification codes to their own email addresses. This method successfully bypassed two-factor authentication and resulted in the takeover of several high-profile accounts before the security loophole was addressed.

AI-powered tools have made writing code much faster, so the bottleneck is now in reviewing and testing it. The ability to define clear goals and properly grok code well is now much more important compared to before.

AI has transformed the prototyping process by removing initial setup bottlenecks, making the creation of functional proof-of-concepts previously considered too complex much faster. This shifts the focus of modern engineering toward high-level architectural planning and defining success metrics for AI agents.

Flowsint is an open-source, graph-based reconnaissance tool for OSINT investigations and visual data exploration that maps relationships between various entities like domains, IP addresses, and social media profiles.

Sandcastle is a provider-agnostic TypeScript library designed to orchestrate and run AI coding agents within isolated, sandboxed environments such as Docker, Podman, or Vercel.

The FROST tracking method allows websites to covertly monitor visitor activity by using JavaScript to analyze the timing of solid-state drive (SSD) interactions, creating a side channel that reveals information about the host system. By processing these timing patterns through a neural network, malicious sites can identify a user's open applications and browser tabs, although the attack's reliance on large storage files makes it detectable.

Parin, a custom game engine built in the D programming language, was created to establish a more code-driven workflow and less opinionated environment. The engine bypasses the garbage collector for critical performance by using features like arena allocators and static data structures, allowing for deep memory control, sub-second compile times, and unified language use for all development needs.

An all-in-one backend that your coding agents can provision and operate directly to ship full stack apps: database, auth, storage, compute, hosting, and AI gateway. Check out the repo →

Failing to account for extreme edge cases in a data model can lead to huge performance issues down the road even when those scenarios were dismissed as unlikely during the initial planning phase.

To succeed in today's changing economic landscape, one's highest priority should be to get comfortable with AI.

Using Jujutsu (jj), a version control tool, allows for an efficient local code review workflow where large changes are managed by duplicating commits and incrementally squashing reviewed files into a dedicated tracking commit.

Standard job applications often rely on arbitrary questions and automated filters that fail to identify top talent effectively, whereas better recruitment requires moving towards direct human connections.
