A DESIGNER'S THOUGHTS ABOUT THIS MOMENT IN AI

The concerning shift from academic AI research to rapid commercialization has created a reckless arms race. This trajectory is fundamentally opposed to the creators' mission of making the world better, as it injects powerful, unknown technology into systems designed to harm rather than help people. Designers and creators now face unprecedented tension between their desire to improve the world and the morally questionable origins of the AI tools they're pressured to use.

FROM SYMBOLS TO SYSTEMS: DESIGNING BRANDS THAT HOLD UNDER PRESSURE

Strong brand systems fail when they're too rigid. Effective brands focus on a few core, non-negotiable elements (like logo, color, and typography) while allowing flexibility to adapt quickly to culture and new media. Resilient branding comes from balancing a stable “anchor” with creative freedom (“volume control”), continuously testing across contexts, and empowering teams to evolve the system rather than strictly follow rules.

THE IDENTITY FOR SPATIAL FESTIVAL FEELS APTLY THREE-DIMENSIONAL

The Spatial festival at Funkhaus Berlin commissioned SMLXL and Gerard Mallandrich to create a dynamic, motion-led identity that reflects its immersive, experimental sound environments. By treating motion as the core of the design and building a responsive 3D visual space, the identity became a living, interactive extension of the festival experience—balancing avant-garde expression with clarity and accessibility.

WHEN IS CODE SECURITY TOO LATE?

There's too much code being generated - and too many bottlenecks at the review and deploy stages. For security to work, it needs to make a big shift to the left.

HOW OPENAI CODEX WORKS

OpenAI's Codex coding agent uses an "agent loop" that iteratively constructs prompts, interacts with the model, and executes tool calls like running commands or tests until a task is complete. Managing the growing conversation history and layered context is done through prompt caching and context window compaction to maintain performance. To support various interfaces, from CLIs to IDEs, OpenAI developed a bidirectional App Server protocol that encapsulates the core agent logic.

HOW SLACK REBUILT NOTIFICATIONS 📣

Slack's notification system had quietly become a mess due to four conflicting preference models, settings that didn't sync across devices, and no clean way to separate “show me activity” from “push me.” They rebuilt it from scratch into one unified model with a simple three-option structure and a single boolean controlling push, migrating millions of users without downtime using a read-time remapping strategy.

THINKING BEATS CODING: HOW TO HIRE THE RIGHT ENGINEERS IN THE AI ERA

Hiring engineers based on framework knowledge is increasingly misguided as AI handles more implementation work. The traits that have always separated strong engineers are systems thinking, reasoning about tradeoffs, and clarifying problems before proposing solutions.

YOU'RE NOT PAID TO WRITE CODE

A dev's job isn't to write code. It's to solve problems, and the best engineers spend more time questioning requirements than typing. Code is a liability that needs to be maintained forever, so the real win is often writing less of it (or none at all).

WHY WE BANNED REACT'S USEEFFECT

Factory banned useEffect in their React codebase after production bugs convinced them it's more trouble than it's worth. Dependency arrays hide coupling, effect chains create race conditions, and it's the first thing AI agents reach for when they don't know what else to do. Almost every real useEffect use case has a better primitive: derive state inline, use a data-fetching library, put logic in event handlers, or use a key prop to force remounts.

THE END OF FRAGMENTATION

Many people think that AI will fragment markets because the technology makes it easier to create software, which means new companies will be built to serve every niche use case. AI will allow clones of major tech companies to emerge to carve out market share. However, it is more likely that AI will drive greater concentration of value into fewer companies and create the biggest businesses of all time. History teaches us that new technology leads to more concentration, and AI has the potential to be the most powerful example of this yet.

THE PARASITE FALLACY

Being a system of record is no longer enough in the age of agents. The value is quickly shifting to the 'system of action'. Databases are cost centers, whereas agents that can complete tasks are value multipliers. Companies that focus on how to tax the consumption of their data rather than how to enable better actions become more of a utility than a platform. The goal should be to create value by being the best place to execute.

WHY PILOTS MATTER MORE THAN YOU THINK—AND HOW TO RUN THEM RIGHT

Pilots are opportunities. When structured intentionally, they can be a powerful tool in sales motion. Pilots accelerate trust, demonstrate value, and lay the groundwork for long-term partnerships. The key is to be clear and intentional, and to keep momentum high. Getting the pilot motion right will result in a far more predictable sales process and a clearer path to scalable revenue.

Open source stress-tests product market fit, as people won't pay for something they won't use for free. You need a bold, boundless mission, but be focused in what you are building. AI makes it even more important to be mindful when choosing what problems deserve your attention. Choosing what to dismiss is a competitive advantage.

BUILD SAAS WITH STRONG OPINIONS

SaaS founders should throw out the old 'configure it all' mentality and do the hard work of figuring out what works best, then sell that as a strongly opinionated piece of software. Businesses will increasingly pay to shortcut their way to best practice rather than buy the tools to do it themselves. This will allow them to focus on their unique value and not waste time reinventing the same sales pipeline used by everyone else. Companies that combine services and software will have a unique advantage.

SIZE OF THE PRIZE AND RUN THE DISTANCE

Nvidia took 3 decades to reach $1T but just 2 years to go from $1T to $5T. At 10% annual compounding, $10T is next. The investing variable that founders and investors consistently get wrong is the size of the prize - nobody imagined Airbnb, DoorDash, or Uber becoming what they are. An outlier founding team can compound a seed into $10B, then $100B in two decades, then $1T in three.

MICRO-APP PORTFOLIOS - 5% HIT RATE, VIBE-CODED EXITS, PORTFOLIO OS

One solo founder launched 70+ projects with zero employees and hit $3.1M ARR. The playbook is portfolio theory applied to startups - ship fast, kill fast, let a 5% hit rate cover the failures. Vibe coding tools like Lovable ($100M ARR in 8 months, $6.6B valuation) and Bolt.new ($40M ARR in 6 months) make the math work by collapsing build time from months to days. A $20-50/app/mo maintenance layer turns the portfolio's biggest liability into recurring revenue.

TECHNICAL LEADERS MAKE THESE 4 COMMON STORYTELLING MISTAKES

Every time you say "well, technically..." you're about to kill a good story. The mistakes that tank most founder pitches all come from the same place - treating all details as equally important. Your audience doesn't want comprehensive, they want compelling. Short anecdotes of 5-15 seconds land better than any 12-step hero's journey, and the hook that gets someone in the door is never the same thing that gets them to stay.

THIS SEVERE AND INTERNATIONAL IPHONE HACK IS THE BEST REASON TO UPDATE TO IOS 26.3 YET

The "DarkSword" exploit chain, active since at least November 2025, chained six flaws across JavaScriptCore (CVE-2025-31277, CVE-2025-43529), dyld PAC bypass (CVE-2026-20700), WebContent sandbox escape (CVE-2025-14174), GPU sandbox escape (CVE-2025-43810), and a local privilege escalation (CVE-2025-43520) to achieve full kernel control on iOS 18.4 through 18.7 via a malicious Safari webpage. Multiple threat actors reused the same core chain across separate campaigns in Saudi Arabia, Turkey, Malaysia, and Ukraine, with delivery methods ranging from Snapchat-themed lures to compromised watering-hole sites, with PARS Defense linked to the Turkey and Malaysia activity. Apple patched all underlying flaws in stages through iOS 26.3 by February 11. Users should update immediately to close the fully patched chain.

DAISY-CHAINING ROGUE RMM TOOLS: HOW THREAT ACTORS ABUSE REMOTE MANAGEMENT SOFTWARE FOR INITIAL ACCESS

Huntress documented a 277% surge in RMM abuse, with threat actors daisy-chaining tools like Action1 and ScreenConnect via MSI installers, wscript, and LLM-generated infostealer scripts to fragment telemetry, distribute persistence, and complicate attribution across campaigns targeting financial accounts and SSA-themed lures. Post-access tradecraft included pin.exe masquerading as Windows Security to harvest login PINs to ScreenConnect\Temp\output.txt, Sordum's HideUL.exe to conceal RMM installs from Add/Remove Programs, and WebBrowserPassView to harvest credentials, with C2 notifications routed through Telegram bots. Defenders should allowlist approved RMM tools explicitly, treat unrecognized RMM activity as suspicious by default, monitor for unexpected MSI installations from user-writable paths, and reference lolrmm.io for visibility into commonly abused platforms.

NEW MALWARE HIGHLIGHTS INCREASED SYSTEMATIC TARGETING OF NETWORK INFRASTRUCTURE

Eclypsium captured two previously undocumented malware variants on March 6: CondiBot, a Mirai-derived multi-architecture DDoS botnet (arm, mips, x86) with 32 registered attack handlers, competitive botnet killing, and C2 beaconing via port 20480 (0x5000) to 65.222.202.53; and Monaco, a Go 1.24.0 SSH scanner and XMRig-based Monero cryptominer attributed to a likely Chinese-speaking actor hosted on Alibaba Cloud (8.222.206.6), brute-forcing ~3.6 billion IPs with 50+ hardcoded credentials and reporting stolen creds back over raw TCP. Both variants exploit the EDR/XDR visibility gap on network appliances by operating below the OS layer. Defenders should monitor for /tmp/monaco, unauthorized chmod 777 operations, unexpected XMRig processes, and apply YARA rules from Eclypsium's full report to detect CondiBot artifacts including the "QTXBOT" string identifier.
