The dominant production failure mode for LLM agents in 2026 isn't bad reasoning — it's capacity. Here's what the data shows, why nobody demos it, and the capacity-engineering patterns that actually keep agents alive under load.

You know that, right? The mobile web is completely unusable. Its garbage and it is garbage because you can't say "no" to stupid advertisers and keep putting more and more stupid popovers and sneaky links, and animations, and content obscuring crap, often not bothering to put the close box within the bounds of the screen. If you work on a mobile version of a website - shame on you. It doesn't work. I'm not kidding. I probably visited, and immediately noped out via the back button because it is just more trouble than the crappy click bait title implies it might be worth. RIP mobile web. submitted by /u/Small_Dog_8699 [link] [留言]

I'm excited to announce Elmo , an open source AEO / AIO / GEO tool that tracks AI visibility. It's the most popular, regularly maintained AI visibility tracker on GitHub. A lot of tools in this space are very expensive or have a lot of lock in. Really you just need to run prompts against LLMs, track mentions, and analyze citations. I'm also using it to improve the AI visibility for Elmo itself (although it's still early days). All you need to run is Docker and a web scraper API key (like BrightData) and OpenAI/Anthropic/Mistral/OpenRouter API key, and you're good to go. There's a lot coming soon (sentiment analysis, content simulations, etc) but it's already in use by a number of e-commerce and SaaS sites. Curious to hear what you think!

From the motivation-pattern-log — a public, dated, falsifiable prediction log for AI-era cybersecurity attack patterns grounded in motivation analysis. Predictions are scored quarterly against stated falsifiers. PREDICTION-20260601-0008 Created: 2026-06-01 Pattern: boredom-with-asymmetric-leverage Substrate: Open-source package registries (npm, PyPI, Crates.io, Packagist) and GitHub Actions CI/CD workflow injection Leading indicator observed: Four distinct, concurrent, cross-registry supply chain campaigns (TrapDoor: 34 packages across npm/PyPI/Crates.io; Megalodon: 5,718 automated commits to 5,561 GitHub repos in six hours; Packagist compromise of 8 packages; Laravel-Lang PHP credential stealer) appeared within a 72-hour window in 2026-W22, all exhibiting automation signatures — throwaway publisher accounts, wave publishing, base64-encoded shell payloads, off-the-shelf delivery via GitHub Releases — consistent with toolkit operation rather than bespoke tradecraft. npm's reactive rollout of 2FA-gated publishing signals registry operators recognizing volume pressure. Predicted window: 2026-Q3 through 2027-Q1 Predicted shape: Automated, low-sophistication credential-stealing and backdoor-planting campaigns against npm, PyPI, Crates.io, and Packagist will continue to increase in incident volume while average per-campaign novelty declines. The dominant operational signature will be scripted account creation, automated package publication across multiple registries simultaneously, and CI/CD workflow injection via forged or compromised GitHub bot identities — all executable with commodity toolkits requiring no original exploit development. At least two registry operators beyond npm will announce reactive publishing controls (mandatory 2FA, namespace-squatting detection, automated malware scanning with publication holds) within the window in direct response to volume pressure. Security vendors will report a measurable increase in "unsophisticated supply chain" incidents re

Ever received a WebSocket tick stream for US stocks and wondered why your indicators behave oddly outside regular hours? The raw data doesn’t tell you which session a trade belongs to, but identifying the session is crucial for signal quality. Here’s a clean, no-dependency-heavy way to do it in Python. Quick Session Reference Session US Eastern Time Data Characteristics Pre-market 04:00-09:30 Sparse trades, choppy moves Regular hours 09:30-16:00 Dense liquidity, smooth price action After-hours 16:00-20:00 Volatility often triggered by news Method 1: Timestamp Conversion Almost every API sends a UTC timestamp. Convert it to US/Eastern and classify. from datetime import datetime import pytz # US Eastern timezone et = pytz . timezone ( ' US/Eastern ' ) def get_session ( ts ): t = datetime . fromtimestamp ( ts , et ) # Check pre-market window if t . hour < 9 or ( t . hour == 9 and t . minute < 30 ): return " pre " # Regular session if t . hour < 16 : return " regular " # After-hours return " after " Method 2: Use a Session Status Field If your provider sends a field like sessionType , you can skip the timezone math. Just make sure to test edge cases at session boundaries. Live Integration Example Using a WebSocket feed (like AllTick’s market data stream) that includes a timestamp, I label ticks on the fly. import websocket import json from datetime import datetime import pytz # US Eastern timezone et = pytz . timezone ( ' US/Eastern ' ) def session ( ts ): t = datetime . fromtimestamp ( ts , et ) if t . hour < 9 or ( t . hour == 9 and t . minute < 30 ): return " pre " elif t . hour < 16 : return " regular " else : return " after " def on_message ( ws , message ): data = json . loads ( message ) s = session ( data [ " timestamp " ]) print ( f " { data [ ' symbol ' ] } | { s } | { data [ ' price ' ] } | { data [ ' volume ' ] } " ) # Open WebSocket connection ws = websocket . WebSocketApp ( " wss://ws.alltick.co/stock " , on_message = on_message ) ws . run_forever () Effic
