https://hackobar.com/item/x-it-was-very-fun-to-hear-ron-tell-the-stories-of-early-jane-s-deac HACKOBAR_ en 2026-05-15 It was very fun to hear Ron tell the stories of early Jane Street. Their first cluster was a pile of 6 Dell boxes in their office. And it was important to them that it be physically in their office so that if something went haywire, they could just physically unplug the machine. Goes without saying that they can no longer fit their 100s of k of GPUs in their office. https://hackobar.com/item/x-rt-by-garrytan-banning-building-new-datacenters-basically-me-2379 HACKOBAR_ en 2026-05-15 RT by @garrytan: Banning building new datacenters basically means: we’ll get stuck with the old ones Instead of better designs we’ll get stuck with evaporative cooling (consumes water) and low energy efficiency. Data centers are not only for AI. They run your critical infrastructure for hospitals, banks, phones, schools - stuff you use every day. Instead of banning new construction - ban bad designs or outdated hardware. If you ban new construction existing datacenters won’t have any reason to innovate, they’ll just crank up the profit. New equipment runs hotter so it makes companies innovate - direct to chip cooling, submersive cooling, adiabatic and hybrid approaches that reduce water usage to almost zero. For example Nebius doesn’t use active cooling in their DC in Finland, they recover the heat and actually use it to warm up houses in local towns in winter. Careful regulation and rebate/tax credit systems can encourage data centers improve quality of life for people around them - improving connectivity, reducing their electric bills (by constructing their own power generation facilities with clean energy), enriching local communities with taxes, all while consuming less water than a couple of green lawns in front of their houses. https://hackobar.com/item/x-congrats-on-the-launch-farzatv-httpswwwycombinatorcomlaunche-3486 HACKOBAR_ en 2026-05-15 Congrats on the launch, @FarzaTV! https://www.ycombinator.com/launches/QNN-this-is-clicky-an-ai-buddy-that-lives-next-to-your-computer-cursor https://hackobar.com/item/newsletter-xai-org-x-algorithm HACKOBAR_ en 2026-05-15 Elon Musk open-sources X's feed ranking algorithm https://hackobar.com/item/news-the-openai-trial-wraps-up-and-the-musk-founder-machine-keeps-9a03 HACKOBAR_ en 2026-05-15 The OpenAI trial wraps up, and the Musk founder machine keeps spinning https://hackobar.com/item/hn-show-hn-claude-code-vs-codex-global-usage-leaderboard-c35b HACKOBAR_ en 2026-05-15 Show HN: Claude Code vs. Codex Global Usage Leaderboard https://hackobar.com/item/x-i-appreciate-how-seriously-the-team-always-takes-these-repor-837a HACKOBAR_ en 2026-05-15 i appreciate how seriously the team always takes these reports (even when the answer turns out to be 'i got used to the current level of magic and now i'd like more please') https://hackobar.com/item/x-icymi-google-autocomplete-search-suggestions-to-expanded-ai--14b1 HACKOBAR_ en 2026-05-15 ICYMI: Google autocomplete search suggestions to expanded AI Overviews https://www.seroundtable.com/google-autocomplete-ai-overview-icon-41330.html https://hackobar.com/item/x-icymi-google-updates-its-spam-policies-to-say-it-applies-als-ec87 HACKOBAR_ en 2026-05-15 ICYMI: Google updates its spam policies to say it applies also to the AI responses, like AI Overviews and AI Mode https://www.seroundtable.com/google-spam-policies-apply-ai-responses-41331.html https://hackobar.com/item/news-openai-feels-burned-by-apples-crappy-chatgpt-integration-ins-5933 HACKOBAR_ en 2026-05-15 OpenAI feels “burned” by Apple’s crappy ChatGPT integration, insiders say https://hackobar.com/item/x-icymi-google-ads-create-videos-beta-httpswwwseroundtablecomg-398e HACKOBAR_ en 2026-05-15 ICYMI: Google Ads "Create videos" beta https://www.seroundtable.com/google-ads-create-video-41321.html https://hackobar.com/item/x-rt-by-garrytan-fun-demo-of-keyframelabs-real-time-video-avat-7f19 HACKOBAR_ en 2026-05-15 RT by @garrytan: Fun demo of @KeyframeLabs' real-time video avatars.

This is a blueprint for understanding what builds AI into its pragmatic parts: what each layer is, where it ends, and where value is accrued. So here’s how you can think about it: 1. Layer 1 - Infrastructure Before any AI model trains or any robot moves, an industrial foundation must exist. Land, energy grids, cooling systems, critical minerals, and fabrication facilities. Infrastructure is the constraint that all the other layers depend on. 2. Layer 2 - Chips Transistors that are etched onto silicon wafers using extreme ultraviolet light. This is what allows both physical and digital AI to take an input, process it, and return a predictive output. The more transistors that fit on a chip, the more computation it can perform. 3. Layer 3 - Data Both digital and physical models train on data. Digital models train on text, code, and images; physical models train on gravity, friction, depth, and sensor streams. The more accurate the data, the more accurate the output. 4. Layer 4 - Models A model is a system that learns from examples. Feed it enough examples of inputs paired with correct outputs, and it adjusts its internal structure until it can predict correct outputs on inputs it has never seen before. LLMs represent a specific class trained on text. They learn by processing billions of examples of human language, developing the ability to write, reason, summarize, and generate code. 5. Layer 5 - Execution This is what lets models take actions on behalf of users. The execution layer lets models pursue objectives through sequential action: observing the environment, reasoning about the next step, acting, and looping until the goal is reached. 6. Layer 6 - Application All of the AI Stack’s revenue originates at the application layer, then goes to the layers below. Every dollar paid for AI is paid for an outcome, a task completed, and an answer delivered. Nobody wants H100s for their own sake. They want H100s because someone, somewhere, wants to run an application. These are the different layers that make up the entire ecosystem of AI. We did a full study on the AI stack.

Vori is the self-driving operating system for supermarkets. Walmart just spent $1B modernizing their digital shelf labels across every single item across every one of their 4,600 stores. At Vori, we’re doing that for all of our customers, bringing Walmart and Amazon-level technology to 75% of the $1.5T food and beverage retail market. Because when grocery stores survive, the entire block thrives. And consumers get freedom of choice - not a future where two companies control every aisle in America. We're increasing the GDP of main street. https://hackobar.com/item/x-rt-by-huggingface-hf-storage-buckets-are-so-underrated-and-m-4ba2 HACKOBAR_ en 2026-05-15 RT by @huggingface: HF storage buckets are so underrated and makes life so much simpler if you're doing anything with data at scale. Before this, it was such a pain when switching between compute providers like Azure, Modal, or AWS. Azure storage is expensive, and the egress costs are insane. I once spent thousands of dollars just to migrate TBs of data off Azure. Now I can simply mount a storage bucket on a Modal compute instance or an Azure/AWS VM and not worry to much https://hackobar.com/item/x-social-capital-my-investment-vehicle-led-the-series-a-in-thi-dd75 HACKOBAR_ en 2026-05-15 Social Capital, my investment vehicle, led the Series A in this company 13 years ago.
