AI optimism meets data center backlash as protesters disrupt Seattle AI Week kickoff

The Washington Technology Industry Association kicked off the third annual Seattle AI Week on Monday with a reminder that AI affects everyone, from engineers and artists to “someone who learned about ChatGPT today,” as WTIA’s Nick Ellingson put it.

“All of us should be a part of that conversation,” he added.

A few people in the audience took that statement literally.

Members of Troublemakers, a Seattle climate activism group, interrupted the week’s opening panel on AI and economic growth several times before they were led out by security. Outside on Elliott Bay, others floated in kayaks with a banner: “Power for People, Not for Tech.”

“These are not your constituents — we are,” one protester told Beau Perschbacher, Gov. Bob Ferguson’s senior policy advisor, as he addressed the large crowd of tech and startup leaders at Seattle’s AI House. Perschbacher was on a panel with Joe Nguyen of the Seattle Metropolitan Chamber of Commerce and Mattie Zazueta of OpenAI, the event’s presenting sponsor.

The group’s main message, according to members who spoke with GeekWire: the rush to build data centers and roll out AI is putting the state’s communities, jobs and environment at risk, and Washington should be investing in green jobs and clean energy instead.

The protest comes amid a broader backlash against data centers in Washington state and across the country. The Seattle City Council voted unanimously in June to pause new large data centers in the city for a year, and Washington AI Resistance organized at least 19 protests around the state this month calling for a statewide moratorium.

The event also came the same day Microsoft offered voluntary buyouts to about 60,000 employees, roughly a quarter of its workforce, as it spends tens of billions of dollars on data centers and AI infrastructure.

The backlash contrasts with a push from the business and tech community for Washington state and the Seattle region to do more to stay competitive in the AI era.

“Washington helped build the technology economy of the last generation. We have an extraordinary opportunity to lead the AI economy of the next,” said former Gov. Chris Gregoire, now CEO of the business group Challenge Seattle, in her opening remarks at the AI Week event.

Gregoire cited efforts to put AI to work on the region’s own problems, including an AI permitting pilot in Everett that she said could cut the median wait for an accessory dwelling unit permit from 252 days to 90. She highlighted the AI-driven protein design work of Nobel laureate David Baker of the University of Washington, with applications in areas including the environment, agriculture and health care.

She also warned that Washington is close to the bottom for its business climate, even though it ranks second in North America for tech talent, as other states court its companies and jobs.

On the panel, Perschbacher said Ferguson’s administration has been focused on data centers since taking office, setting up a work group early last year to study their impact. The group looked for a Washington community that had been harmed by a data center and couldn’t find one, he said.

He added that the state won’t permit data centers to run diesel generators around the clock, and that their water use turned out to be “not out of line with a typical industrial user.”

Electricity is a different story. Data centers “use a really significant amount of electricity,” he said, and with demand also rising from EVs and heat pumps, getting enough power “is a major challenge.”

Perschbacher addressed the protesters directly, saying Washington has some of the strictest environmental laws in the country and that the state’s data center work group reinforced those rules rather than weakening them. Bills on ratepayer protections and transparency for data centers are likely to come back in the next legislative session, he said.

The issue also came up in the event’s second panel, on AI policy. State Sen. Marko Liias, who sponsored a bill this year on high-risk uses of AI, said data centers that want to locate in Washington need to meet “stringent expectations,” including adding clean energy to the grid, recycling water and dropping nondisclosure agreements that keep communities in the dark. Washington’s goal “has never been to be the cheapest or easiest place,” he said.

“When energy becomes scarce, I do think we need to be clear that our communities deserve access to that energy before the data centers do,” Liias said.

Joe Braidwood, founder of AI governance startup Glacis, which works out of AI House, said on the same panel that it was the first event he’d attended there with a public protest. “I think that’s actually kind of promising that people care enough to want to come together and talk and disagree and figure this out,” he said.

Zazueta, OpenAI’s global head of community programs, said in the opening panel that the industry needs to do a better job showing people the benefits of AI. Many people “read about these scary headlines,” she said, but don’t see how the technology applies to their daily lives.

OpenAI runs AI literacy workshops and trains libraries and community groups to lead their own, she said. The company opened an expanded office in Bellevue in March, its largest engineering center outside San Francisco.

Speaking with GeekWire outside the event on Monday afternoon, one of the protesters who had interrupted the panel singled out that remark. She said it dismissed public concerns about AI as the product of bad headlines, and she objected to the idea of using community groups to win people over to the benefits of artificial intelligence.

“They want to infiltrate our communities,” she said.

The opening panel with Zazueta, Perschbacher and Nguyen was titled “The Abundance State: Washington’s Chance to Lead the AI Future.” The protester objected to that framing, saying the panelists’ idea of abundance came down to easing permits for data centers.

It wasn’t the first time the group has protested the tech industry’s energy use. In 2024, it blocked entrances at Amazon’s Seattle headquarters to protest the company’s plans to power data centers in Oregon with natural gas.

Inside the event on Monday, as the interruptions continued, Nguyen, a former state senator who now leads the Seattle chamber, had responded to the protesters directly. “If you want to have your own event, have your own event,” he told them.

After they were led out, Nguyen said he agreed with the protesters, calling their passion “very warranted.” Those concerns are one reason Washington created some of the most stringent energy policies in the country, he said, adding that everyone would be better off if data centers elsewhere were held to the same standards.

“I think we’re very unique in Washington state to be able to actually do this in a way that really is mindful of our values, of the environment, and also pushing for innovation as well,” he said.

At the same time, Nguyen said demand for AI and data centers is market-driven, and it isn’t fair to criticize data centers while using them every day.

“For anybody who’s upset with data centers, I hope that when you email me, don’t email me,” he said. “Print it off and walk it to my office.”

Shipping Flutter Web to Firebase When Your GitHub Actions Budget Hits Zero

1 Share

On October 18, right in the middle of shipping a multi-feature audit and a supplement tracker redesign on my personal life_os_app (my daily Flutter Web + Cloud Firestore operating board), GitHub Actions stopped scheduling jobs. The billing meter for my personal account's hosted runner minutes had hit 100%.

Look at what my .github/workflows/ci.yml and deploy-live.yml were doing on every push and pull request:

  1. Spinning up an ubuntu-latest VM.
  2. Pulling the Flutter SDK and warming the Pub cache (~90s).
  3. Installing Python 3 and running 68 CLI sync unit tests (~15s).
  4. Running flutter analyze and 466 widget and accessibility tests (~110s).
  5. Compiling flutter build web --release --no-web-resources-cdn (~140s).
  6. Authenticating via Workload Identity Federation (google-github-actions/auth@v2) and deploying to Firebase Hosting target board (~35s).

That is 6.5 minutes per PR push and another 4 minutes on merge to main. Across 70+ PRs in October, a single-developer personal project burned through thousands of CI minutes doing work my local Apple Silicon MacBook finishes in under 35 seconds.

When your CI budget hits zero on a personal repo, you have two choices: pay for extra runner minutes to compile code your laptop already compiled, or build a deterministic local verification and deployment pipeline that is faster and safer than the YAML workflow it replaces.

Here is the exact architecture I use to keep life_os_app shipping to Firebase Hosting and Cloud Firestore with zero GitHub Actions spend.

Architecture: The Three-Layer Local Verification Gate

Moving deploys to your local machine only works if you never deploy unverified state. In life_os_app, the application state is split across two runtimes:

  • Python 3.14 CLI Sync Tools (tool/board_*.py): Morning and evening scripts that pull from Apple Reminders, Google Calendar, Harvest, Notion, and GCP Billing, then write structured JSON documents into Cloud Firestore over REST.
  • Flutter Web Client (lib/): A Riverpod 3 + Material 3 multi-skin web app served from Firebase Hosting with a custom offline Service Worker (web/offline-sw.js).

Layer 1: Firestore Schema Validation Before Every REST Write

One of the biggest risks of running CLI sync tools outside a container is accidentally clobbering fields that the Flutter Web client writes directly from the browser. For example, on the Events and Admin tabs, I tick tasks directly in the UI (config/events.taskTicks and config/admin.done), while tool/board_events.py and tool/board_admin.py sync metadata from Notion and GCP Billing.

To prevent a CLI run from wiping browser taps, tool/board_firestore.py enforces two rules before any HTTP PATCH leaves the machine:

  1. Explicit schema validation on every collection (dayPlans, stats, config, finance, plan).
  2. Field-level update masks (?updateMask.fieldPaths=...) plus hard blocks against overwriting client-owned map keys:
# tool/board_firestore.py
if path == "config/events" and "taskTicks" in data and not fields:
    raise SystemExit(
        "refusing to overwrite config/events.taskTicks without --fields; "
        "pass --fields updated,source,events"
    )
if path == "config/admin" and "done" in data and not fields:
    raise SystemExit(
        "refusing to overwrite config/admin.done without --fields"
    )

In addition, caching the gcloud auth print-access-token call with @functools.lru_cache(maxsize=1) and enforcing a 15-second socket timeout cut multi-document Firestore sync latency by 80% and eliminated hanging background processes when switching Wi-Fi networks.

Layer 2: Per-Document Decode Isolation in Flutter Streams

In Cloud Firestore, a single malformed field inside one historical document in a collection query (collection('dayPlans').snapshots()) will normally throw a FormatException or TypeError inside .map(), killing the entire StreamProvider and replacing your UI with an error state.

During my audit pass, I hardened every repository to isolate decoding per document:

// lib/features/day_board/data/board_repository.dart
List<T> _decodeEach<T>(
  QuerySnapshot<JsonMap> query,
  T Function(JsonMap data, String id) decode,
) {
  final results = <T>[];
  for (final doc in query.docs) {
    try {
      results.add(decode(doc.data(), doc.id));
    } on Object catch (error, stackTrace) {
      developer.log(
        'Skipping malformed document ${doc.reference.path}',
        name: 'day_board.repository',
        error: error,
        stackTrace: stackTrace,
      );
    }
  }
  return results;
}

When saving multi-day edits (such as editing 7 days of focus blocks and habit notes in the This Week sheet), replacing 14 sequential await set() calls with a single atomic WriteBatch (saveWeekEditsBatch) eliminated partial-save race conditions on flaky mobile connections.

Layer 3: Self-Contained Web Bundles (--no-web-resources-cdn) & Service Worker Cleanup

When deploying Flutter Web to Firebase Hosting for daily use on iPhone, iPad, and desktop, CDN font/CanvasKit fetches can stall on airplane or train Wi-Fi. Building with --no-web-resources-cdn bundles CanvasKit and font assets directly into build/web/, paired with a custom web/offline-sw.js that races network against a 3.5-second timeout before falling back to cache:

// web/offline-sw.js
function networkFirst(request, timeoutMs) {
  return new Promise((resolve, reject) => {
    const timer = setTimeout(() => reject(new Error('timeout')), timeoutMs);
    fetch(request)
      .then((response) => {
        if (response && response.ok) {
          caches.open(CACHE).then((cache) => cache.put(request, response.clone()));
        }
        resolve(response);
      })
      .catch(reject)
      .finally(() => clearTimeout(timer));
  }).catch(() => caches.match(request));
}

Notice the .finally(() => clearTimeout(timer)) cleanup: without it, every fast network response leaves an orphan timer running until timeoutMs expires.

Benchmarking: Cloud CI vs. Local Verification Gate

Stage GitHub Actions (ubuntu-latest) Local Apple Silicon Gate Improvement
Python CLI Unit Tests (68 tests) 14.2s (with setup) 0.02s 710x faster
Dart Format + Analyze + 466 Flutter tests 118.0s 14.5s 8.1x faster
flutter build web --release --no-web-resources-cdn 142.0s 14.8s 9.6x faster
firebase deploy --only hosting:board 34.0s 3.1s 11.0x faster
Total Wall-Clock Time ~5m 08s (plus SDK cache) ~32.4s ~9.5x faster, $0 CI cost

Table totals exclude the Flutter SDK download and Pub cache warm-up (~90s), which is what brings a full PR run to ~6.5 minutes.

Key Takeaways for Flutter & Firebase Engineers

  1. Keep CI YAML for PRs when budget allows, but make your local gate identical. A single local command (dart format -l 120 lib/ test/ && flutter analyze && python3 -m unittest discover -s tool -p '*_test.py' && flutter test) guarantees parity before firebase deploy.
  2. Use Firebase Hosting multi-site targets (hosting:board, hosting:board-staging). Mapping targets in .firebaserc lets you preview on staging or promote to live with --only hosting:board without touching sibling sites on the same GCP project.
  3. Never let one bad Firestore document take down a collection stream. Wrap per-document .fromJson() calls inside a helper that logs to dart:developer and skips the corrupted record.
  4. Test accessibility contrast and 44pt tap targets in flutter test, not in production. Running textContrastGuideline and androidTapTargetGuideline with GoogleFonts.config.allowRuntimeFetching = false catches neon text shadow contrast drops and 32pt icons in milliseconds.

The complete local release gate in one command:

dart format -l 120 lib/ test/ && \
  flutter analyze && \
  python3 -m unittest discover -s tool -p '*_test.py' && \
  flutter test && \
  flutter build web --release --no-web-resources-cdn && \
  firebase deploy --only hosting:board --project esra-life-os

Why NVIDIA RTX Spark and DGX Spark End 30 Years of Traditional PC Architecture with 128GB Unified Memory

1 Share

Since the mid-1990s, every desktop and laptop PC has followed the exact same blueprint: an x86 CPU connected to system RAM on one side, and a discrete GPU wired to separate VRAM across a narrow PCIe bus on the other. While that split architecture powered three decades of spreadsheets, web browsers, and rasterized games, it hits a brick wall when you try to run a 120-billion-parameter AI agent locally on your desk.

 

With the rollout of the NVIDIA DGX Spark and GB10 Grace Blackwell Superchip alongside the Windows-powered RTX Spark (N1X) platform, NVIDIA CEO Jensen Huang has declared the end of thirty years of traditional PC architecture. In this hardware guide, we examine why the split CPU-GPU memory wall is dead, how NVLink-C2C unifies 128 GB of memory on a single 3nm chip, and how local autonomous agents reshape your next PC.

 

NVIDIA Kills the Traditional PC - RTX Spark, DGX Spark, and GB10 Unified Memory Architecture
NVIDIA's GB10 Grace Blackwell Superchip and RTX Spark N1X SoC replace 30 years of separated x86 CPU RAM and PCIe GPU VRAM with 128 GB of NVLink-C2C coherent unified memory.

 

Table of Contents

 

  • End of the 1995 Split Memory Bus: Eliminates the separate CPU system RAM and PCIe GPU VRAM bottleneck that has restricted PCs for three decades.
  • 128 GB Coherent Unified Memory: Fuses a 20-core Arm Grace CPU and a 6,144-core Blackwell GPU over NVLink-C2C with up to 128 GB of shared LPDDR5X memory at up to 300.8 GB/s bandwidth.
  • 1 PetaFLOP Local FP4 AI Compute: Delivers fifth-generation Tensor Cores capable of running 120B to 200B parameter models and 90 GB 3D OptiX scenes locally on a laptop or mini-desktop.
  • Windows Kernel & OpenShell Overhaul: Pairs Microsoft's unified memory page-table upgrades and 20-core workload scheduler with the sandboxed NVIDIA OpenShell agent runtime.
  • Multi-Node ConnectX-7 Clustering: Links up to four DGX Spark units over 200 Gbps QSFP interconnections to run 700-billion-parameter frontier models across 512 GB of memory.

 

 

Why Thirty Years of Split CPU and GPU Memory Hit a Wall

To understand why NVIDIA declared the traditional PC architecture obsolete, look inside any high-end desktop or gaming laptop built since 1995. Even if you install 128 GB of DDR5 system memory alongside an flagship discrete graphics card on a modern Windows 11 developer workstation, your GPU can only address its own soldered 16 GB or 24 GB pool of GDDR VRAM at full speed.

 

Whenever a local LLM or 3D scene exceeds that 16 GB VRAM ceiling, the system shuttles tensors across the slow PCIe bus. As software shifts from static chat to always-on agentic AI, PCs no longer just await mouse clicks.

 

Instead of manually clicking menus, autonomous local agents observe your screen, orchestrate tools like Rhino, Blender, and Visual Studio, and hold 120-billion-parameter weights plus 1-million-token context windows directly in unified memory.

 

 

Inside the GB10 Grace Blackwell Superchip and RTX Spark N1X Silicon

NVIDIA demolishes the PCIe memory wall by bringing its data-center superchip design down to personal computers through the NVIDIA GB10 Grace Blackwell Superchip and the closely related NVIDIA RTX Spark (N1X) SoC. Co-engineered with MediaTek on TSMC's 3nm process with 70 billion transistors, the silicon integrates thirty years of CUDA, RTX ray tracing, and Tensor Core engineering onto a single package.

 

On the compute side, the chip pairs a custom 20-core Armv9.2 Grace CPU (configured with 10 high-performance Cortex-X925 cores clocking up to 4.1 GHz and 10 high-efficiency Cortex-A725 cores) with a Blackwell GPU packing 6,144 CUDA cores, 5th-Gen Tensor Cores, and 4th-Gen RT Cores. Rather than communicating over a slow PCIe lane, the Grace CPU and Blackwell GPU connect via NVIDIA NVLink-C2C chip-to-chip interconnect.

 

This NVLink-C2C fabric gives both the CPU and GPU zero-copy, cache-coherent access to a single 64 GB or 128 GB 256-bit LPDDR5X unified memory pool delivering 273 GB/s to 300.8 GB/s of bandwidth. Rated at up to 1 petaFLOP of sparse FP4 AI performance within a 45W–80W laptop envelope (or 140W TDP in compact desktops), an RTX Spark laptop like the Microsoft Surface Laptop Ultra can render a 90 GB 3D OptiX scene, decode 12K 4:2:2 video, run AAA games at 1440p over 100 FPS with DLSS 4.5 Ray Reconstruction, and host a 120B LLM simultaneously.

 

 

Rewriting the Windows Kernel and Securing Local Agents with OpenShell

Dropping 128 GB of coherent unified memory into a laptop required Microsoft and NVIDIA to re-architect core memory and scheduling subsystems inside Windows 11 26H2. Microsoft lifted the legacy Windows upper limit on system memory addressable by the GPU, introduced large shared-memory page management so CPU and GPU tasks dynamically partition memory without page-table thrashing, and built a heterogeneous 20-core workload profile scheduler backed by the Microsoft Power and Thermal Framework.

 

Meanwhile, the Windows 11 Prism emulator runs x86 apps alongside native Arm64 builds of Blender, Premiere, and Easy Anti-Cheat, while developers migrate legacy x86 code to Arm via the Model Context Protocol (MCP).

 

Because an autonomous desktop agent can read local files and control applications, running agents without OS-level containment is a massive security risk. NVIDIA and Microsoft solved this by introducing new Windows security primitives alongside the NVIDIA OpenShell sandboxed agent runtime and the NemoClaw open agent blueprint stack—which enforce strict user-defined privacy policies, isolate local agent execution, and strip personal data before escalating complex queries to cloud models.

 

 

Scaling to Two Hundred Billion Parameters on Your Desk with DGX Spark

For AI researchers, data scientists, and robotics engineers who prefer an Ubuntu-based Linux environment that mirrors data-center clusters, the NVIDIA DGX Spark packs the GB10 Grace Blackwell Superchip, 128 GB of coherent unified memory, and up to 4 TB of self-encrypting NVMe storage into a 1.2 kg palm-sized chassis running NVIDIA DGX OS. Out of the box, a single DGX Spark fine-tunes models up to 70 billion parameters and runs local inference on models up to 200 billion parameters.

 

Even more impressively, every DGX Spark includes dual rear QSFP ports powered by an integrated NVIDIA ConnectX-7 SmartNIC running at 200 Gbps. Using the NVIDIA Sync Cluster Assistant, you can link two DGX Spark boxes directly with a single QSFP112 DAC cable (no network switch required) to create a 256 GB desktop cluster for 400B-parameter models, or connect four units through a 200 GbE RoCE v2 switch to unlock 512 GB of unified memory for 700-billion-parameter frontier models.

How Developers Should Prepare for the Post-Traditional PC Era

Whether you build enterprise .NET microservices, 3D pipelines, or local AI agents in Kolkata or Bengaluru, you can prepare your engineering stack for unified-memory Arm PCs using four practical steps:

 

  1. Compile Native Arm64 Targets: Configure your Visual Studio 2026 and CI/CD pipelines to emit native `linux-arm64` and `win-arm64` binaries so your apps utilize the 10 Cortex-X925 and 10 Cortex-A725 cores without emulation overhead.
  2. Eliminate Redundant Host-to-Device Copies: Audit your CUDA, PyTorch, and DirectX memory allocations to take advantage of NVLink-C2C unified memory pointers instead of staging buffers across PCIe.
  3. Adopt Sandboxed Local Agent Frameworks: Package your desktop automation tools using MCP servers and test them inside the NVIDIA OpenShell runtime and NemoClaw blueprints so local agents operate with strict file and network guardrails.
  4. Size Your Hardware by Parameter Count: Choose an RTX Spark laptop (such as the Surface Laptop Ultra, ASUS, Dell, HP, Lenovo, or MSI models) for mobile 120B-parameter agent workflows and gaming, or deploy clustered DGX Spark nodes on your desk for 200B–700B model prototyping.

 

 

Frequently Asked Questions (FAQ)

  1. Why did NVIDIA say the traditional 30-year-old PC architecture is dead?
    For 30 years, traditional PCs separated CPU system RAM from discrete GPU VRAM across a narrow PCIe bus and relied on manual point-and-click app execution. That split memory architecture cannot hold massive 100B+ parameter AI models and 90GB 3D scenes locally, prompting NVIDIA to replace it with coherent unified-memory superchips built for autonomous local agents.
  2.  

  3. What are the exact specifications of the NVIDIA GB10 Grace Blackwell Superchip and RTX Spark N1X?
    Built on TSMC's 3nm process with 70 billion transistors in collaboration with MediaTek, the silicon features a 20-core Arm Grace CPU (10 Cortex-X925 + 10 Cortex-A725 cores), a Blackwell GPU with 6,144 CUDA cores and 5th-Gen FP4 Tensor Cores delivering up to 1 petaFLOP of AI performance, NVLink-C2C interconnect, and up to 128 GB of 256-bit LPDDR5X unified memory.
  4.  

  5. How does NVLink-C2C unified memory differ from traditional PCIe GPU memory?
    Instead of copying data between separate CPU RAM and GPU VRAM over PCIe, NVLink-C2C provides a high-speed, cache-coherent chip-to-chip interconnect that lets both the 20-core Arm CPU and Blackwell GPU access the exact same 64 GB or 128 GB LPDDR5X memory pool at up to 300.8 GB/s.
  6.  

  7. What is the difference between NVIDIA RTX Spark and NVIDIA DGX Spark?
    NVIDIA RTX Spark (N1X) powers Windows 11 laptops and compact desktops (45W–80W TDP) designed for local AI agents, creative apps, and AAA gaming with DLSS 4.5. NVIDIA DGX Spark (GB10) is a 1.2 kg, 140W TDP desktop AI supercomputer running Ubuntu-based NVIDIA DGX OS with dual 200 Gbps ConnectX-7 ports for multi-node AI model fine-tuning and inference.
  8.  

  9. How large of an AI model can run locally on a single DGX Spark or a 4-node cluster?
    A single 128 GB DGX Spark can fine-tune models up to 70 billion parameters and run inference on models up to 200 billion parameters. By linking four DGX Spark systems via 200 Gbps NVIDIA ConnectX-7 networking, you can pool 512 GB of unified memory to run frontier models up to 700 billion parameters locally.
  10.  

  11. How did Microsoft modify Windows 11 to support NVIDIA RTX Spark?
    Microsoft raised the maximum system memory limit accessible to the GPU up to 128 GB, enhanced shared-memory page size management for heavy unified-memory workloads, added heterogeneous 20-core workload profile scheduling, and expanded the Windows 11 Prism emulator for x86 apps and games.
  12.  

  13. What are NVIDIA OpenShell and NemoClaw?
    NVIDIA OpenShell is a sandboxed runtime that enforces user privacy policies, isolates local autonomous agents, and strips sensitive personal data before queries reach the cloud. NemoClaw is NVIDIA's open blueprint stack for deploying secure, always-on autonomous agents like OpenClaw and Hermes Agent.
  14.  

  15. Can NVIDIA RTX Spark laptops run traditional x86 Windows games and anti-cheat software?
    Yes. RTX Spark supports AAA gaming at 1440p over 100 FPS with hardware ray tracing, DLSS 4.5 Ray Reconstruction, and Reflex, backed by the Windows 11 Prism emulator and native Arm anti-cheat support from Epic Easy Anti-Cheat and BattlEye.
  16.  

  17. Which PC manufacturers offer NVIDIA RTX Spark and DGX Spark systems?
    OEM partners shipping RTX Spark and DGX Spark systems include Microsoft (Surface Laptop Ultra and Surface RTX Spark Dev Box), ASUS, Dell, HP, Lenovo, MSI, Acer, and Gigabyte.
  18.  

  19. Can I connect two DGX Spark systems together without buying a 200 GbE network switch?
    Yes. You can connect two (or three) DGX Spark systems directly using a single approved QSFP112 DAC cable across their rear 200 Gbps ConnectX-7 ports and configure the cluster using the NVIDIA Sync Cluster Assistant without an external switch.

 

 

End Note

Just as smartphones transformed mobile phones from voice-call handsets into pocket computers, NVIDIA's GB10 and RTX Spark architecture transforms the personal computer from a manual application launcher into an autonomous agent workstation. By fusing a 20-core Arm Grace CPU, a 6,144-core Blackwell GPU, and 128 GB of coherent unified memory over NVLink-C2C, the thirty-year-old PCIe memory bottleneck is officially history.

 

If your daily workflow involves local LLM fine-tuning, multi-agent orchestration, or massive 3D rendering scenes that choke a 16 GB or 24 GB discrete graphics card, unified-memory Grace Blackwell desktops and laptops represent the biggest architectural leap since 1995.

Scale One AI Agent Across Sites (Part 2)

1 Share
From: Microsoft Developer
Duration: 3:53
Views: 322

Manufacturers don't have to choose between running AI agents in the cloud or on site. A hybrid model uses one agent framework, built on common data contracts and guardrails, so the same agent runs in the cloud, at the edge, or fully disconnected, with every instance managed through a single interface.
Christoph Berlin, Vice President of Engineering for Cloud and AI at Microsoft, picks up from Part 1's root cause example to tackle scale: how to run an agent across many sites without building it over and over. He closes with two lessons for agentic AI in manufacturing.

Continuous Delivery Office Hours Ep.12: The platform adoption shock

1 Share

In the previous episode, we covered organizational culture, including why posters aren’t the way to change culture, crucial theoretical foundations from Douglas McGregor and Ron Westrum, the impact of arbitrary deadlines, and why feedback keeps organizations healthy.

This episode examines Platform Engineering and the persistent debate between mandatory and optional adoption strategies. The episode was inspired by data from our Future of Platform Engineering report.

Watch the episode

You can watch the episode below, or read on to find some of the key discussion points.

Watch Continuous Delivery Office Hours Ep.12

The rise of mandatory platforms

Mandatory platforms have been an issue in the past, with platform producers and consumers diverging dramatically on whether a platform is successful. Part of the perception gap comes down to platform teams losing the adoption signal: if everyone must use the platform, you’ve lost a way to discover gaps and flaws in what you provide.

Since then, platforms have become broader. Platforms now have almost 6x as many features as they did when the perception gap was present. As platforms take on tasks that developers truly appreciate, like security and compliance, the gap between producers and consumers has closed.

You might think of this like the difference between being forced to use a bicycle to travel both before and after the invention of the bicycle saddle. Riders are far happier to be forced to cycle when they have a cushioned seat.

Alongside the dissipation of perceptual differences, it turns out mandatory platforms outperform optional platforms in terms of goal attainment. However, there are many factors contributing to platform success, like monitoring developer satisfaction and regularly eliciting feedback to help improve the platform.

The other factors of platform success have more impact, and you should still consider optional adoption, but combined with mandatory policies. That means development teams have to meet the same standards they would meet if they adopted the platform, which makes platform adoption more appealing and less likely to cause conflict or friction.

Not just more features, but the right ones

The most common number of features baked into a platform was four, but that has grown to 24. Platforms are getting broader, and these wider platforms are more successful than the tiny ones of the past. Despite this link between platform breadth and goal attainment, it’s important to bear in mind that the volume of features alone is not a sufficient strategy, and that choosing to solve the right problems is the path to success.

Maintaining regular contact with developers, lightly assessing their satisfaction with the platform, and dedicating time to conversations that shape your platform’s direction are all part of the high-performance platform playbook. The usefulness comes from solving the right problems, and you need to focus on developer needs to make the right choices.

Platform teams are rediscovering many of the capabilities of the State of DevOps research and its associated model, like Lean Product Management, which prove useful in building platforms as internal products.

The invisible platform dilemma

Unsurprisingly, platforms that meet more goals have higher budget safety. They are showing a return on investment, so they can be confident in maintaining their funding over the long run. Platforms that fail to meet their goals are more likely to have their budgets redirected to other initiatives.

Platform teams need to show the value back to the organization in terms the organization understands and for measures it cares about. With AI initiatives soaking up money, some organizations will start reallocating funds and focus, leaving platforms underfunded or dropped.

Some of the best platforms will be invisible in daily use because developers don’t have to keep interacting with them. These boring, invisible platforms are the most valuable, but the least visible. Providing metrics and proof of value for these platforms will keep them funded.

Happy deployments!

Continuous Delivery Office Hours is a series of conversations about software delivery, with Tony Kelly, Bob Walker, and Steve Fenton.
