The company didn't immediately say what went wrong. SpaceX's stock plunged more than 4% in after-hours trading before paring losses.

Don't expect that number to shrink any time soon.

One features an optical illusion spoof of 'They Live.'

I've written Mojibake because I don't like the other Unicode libraries for Unicode support. It consists of only two amalgamation files: mojibake.h and mojibake.c. I've added all the most important Unicode algorithms, such as normalization, case conversion, segmentation, bidirectional text, collation, confusable, and others. I regularly test it in these OSes: Linux, macOS, FreeBSD, OpenBSD, NetBSD, and Windows 11. You can find a WASM demo on that site of all the public API functions and the docum

On today’s Uncanny Valley, we unpack OpenAI’s ongoing drama, both legal and reputational, and whether these developments could further hurt the company—particularly in its fight against Anthropic.

Today I'm excited to launch RegionCheck , a tool for testing, monitoring, and debugging endpoints from cloud regions around the world. The idea is simple - test an endpoint's DNS and HTTP connectivity and response from a defined set of cloud regions. Whether you're troubleshooting an API, validating a deployment, checking DNS propagation, or investigating latency, seeing the results from multiple cloud regions can quickly reveal issues that aren't obvious from your own machine. What is RegionCheck? RegionCheck lets you run endpoint checks from AWS, Azure, and Google Cloud regions without provisioning infrastructure or maintaining test instances. Current capabilities include: HTTP endpoint testing DNS lookups TLS certificate validation Continuous monitoring with alerts Side-by-side comparison across cloud providers and regions Shareable result pages for collaboration API/MCP access for automation and agents Why I built it When debugging production issues, I often wanted to answer questions like: Is DNS returning the same result everywhere? Or is geo-DNS returning the results intended? Is TLS certificate propagation for my CDN working as intended? Is one region significantly slower than another? Is my CDN caching working as expected? Are my geo-HTTP redirects working as intended? (For some interesting examples try www.yahoo.com and www.cnn.com in non-US regions) There are many tools that exist that provide these answers, but nothing that answers all of these questions in one place. That's what RegionCheck aims to provide. Who it's for RegionCheck is designed for engineers who work with cloud infrastructure, including: DevOps engineers Site Reliability Engineers (SREs) Platform engineers Backend developers Anyone who likes to take a peek at backend infrastructure Try it out RegionCheck is available at https://regioncheck.io You can run free checks directly from the website; or create an account to access monitoring, alerting, the API, and additional features. I'd love

Most people open /etc/hosts , change one line, refresh the browser, and hope. That works until it does not. Then you spend twenty minutes on Permission denied , a forgotten DNS flush, or a commented line from last week that is still active. This is a simple workflow that keeps hosts edits boring. What the hosts file does When your machine resolves a name like myapp.test , it can use a local override before public DNS. Common cases: Point myapp.test to 127.0.0.1 for local work Point a real domain at a staging IP before DNS cutover Temporarily block a host with 0.0.0.0 Give services readable names instead of raw IPs The idea is simple. The mess comes from how people edit and apply it. A workflow that holds up 1. Do not treat /etc/hosts as your only copy Keep a file you own: ~/dev/hosts/personal.hosts Or one file per project / client. Edit that. Apply it on purpose. 2. Edit the copy, then copy it into place macOS / Linux: code ~/dev/hosts/personal.hosts sudo cp /etc/hosts "/etc/hosts.bak. $( date +%Y%m%d-%H%M%S ) " sudo cp ~/dev/hosts/personal.hosts /etc/hosts Windows: edit your copy, back up the live file, then replace: C :\ Windows \ System32 \ drivers \ etc \ hosts You need admin rights for the live file. That is normal. 3. Flush DNS every time you apply Make this part of the apply step, not a later panic search. macOS sudo dscacheutil -flushcache ; sudo killall -HUP mDNSResponder Windows (Admin) ipconfig /flushdns Linux (systemd-resolved) sudo resolvectl flush-caches 4. Verify in the terminal before the browser ping -c 1 myapp.test # Linux: getent hosts myapp.test Right IP in the terminal, wrong page in the browser? Stop rewriting hosts. Look at browser DNS, HTTPS, redirects, or HSTS. 5. Avoid two active lines for the same hostname This breaks people constantly: 10.0.0.5 www.client.com 127.0.0.1 www.client.com Pick one. Comment the other, or better, keep separate profile files and swap the whole file. Example: local frontend + API 127.0.0.1 shop.test 127.0.0.1 api.

E.g. what if someone prompts an LLM to solve the Riemann hypothesis using this or that approach; and the model actually solves it. Who gets the prize?

A competitor intelligence agent enables real-time pricing visibility, automated positioning tracking, and structured competitor briefs for brands without manual research. At the center of these workflows are a researcher agent responsible for gathering data and an analysis agent responsible for generating a summary and a downstream report. However, one of the things that makes the researcher agent's output trustworthy is its retrieval layer, since a poor retrieval-layer output can make the analysis agent's recommendation questionable. If the researcher agent searches the webpage and retrieves a challenge page, an empty response, or blocked content, every downstream conclusion becomes less trustworthy. With a 99.93% success rate on protected websites, ZenRows provides the reliable retrieval layer that makes these workflows practical in production. This tutorial shows why a CrewAI researcher agent can fail on protected competitor pages. It starts with a custom ZenRows-based tool setup, then later shows the MCP server as an alternative approach. Prerequisites This tutorial works best with Python 3.10 or newer. If you are on an older Python version, create a dedicated virtual environment with a current Python installation to avoid dependency conflicts. Python 3.10 to 3.13. CrewAI requires this range. ZenRows API key. Create an account at zenrows.com and copy your key from the dashboard. This key authenticates every scrape the researcher agent runs for data extraction. Anthropic API key. The crew uses Claude to drive both agents. Generate a key in the Anthropic Console. Install dependencies and the required packages using pip install "crewai[anthropic]" crewai-tools zenrows python-dotenv . Create a .env file and save your API keys there. Why the built-in ScrapeWebsiteTool fails on competitor pages The problem, as established earlier, starts before the analysis. A CrewAI workflow depends primarily on the information collected, because a competitor intelligence agent relie
