The applications are in, and the TechCrunch Startup Battlefield team made their decisions!

The Cosmos EV is now slated for release in the second half of 2027. CEO Silvio Napoli said he's focused on getting the EV right, as well as its nearer-term robotaxi project with Uber and Nuro.

Reddit is expanding its moderation tools and building stronger abuse prevention systems that it says could eventually reduce communities’ reliance on karma and account-age requirements, making it easier for legitimate newcomers to participate.

The legendary Google executive is joined by other outgoing Google execs in a joint mission to use AI to push forward the process of scientific discovery.

In today's enterprise world, users expect applications to be fast, reliable, and always available. As businesses grow, traditional databases alone often struggle to handle increasing traffic and real-time demands. This is where Redis becomes a game changer. What is Redis? Redis (Remote Dictionary Server) is an open-source, in-memory data store that can be used as a cache, database, message broker, and streaming engine. Because it stores data in memory instead of on disk, Redis delivers r...

A few years ago, the default test automation decision was mostly technical. Do we use Selenium? Which language? Where do we run the grid? Today, the menu is much larger. You can write Playwright tests, ask Claude to generate them, use an AI-first testing platform, or combine several of those approaches. That sounds like progress, and it is. But more choices have also made it easier to optimize for the wrong thing. Teams compare how quickly the first test can be created. They should b...

Most Solidity security tools have the same failure mode: they cry wolf. You run them on an audited protocol and get 600 "findings," 98% of which are noise. The signal drowns. Worse — send a client a report full of false positives once, and you've burned your credibility. I've been building a scanner with the opposite goal: report almost nothing, but be right when it does. Zero false positives, verified across the entire OpenZeppelin library. Here's how that actually works, with three real...

A lot of QA work is not really test execution. It is ambiguity management. What does this requirement mean? Is this visual difference intentional? Did the test fail because of the product, data, browser, or test code? Does this issue block the release? When testing systems are weak, every failure starts a meeting. When they are strong, the evidence narrows the decision before the conversation begins. Spreadsheets are often a symptom Many teams still manage te...

Amazon Redshift is an AWS-native cloud data warehouse for batch BI, reporting, and large analytical workloads. The question in 2026 is not whether Redshift still works. It is whether its execution model, scaling controls, and billing mechanics fit workloads that now require continuous ingestion, predictable p99 latency, and high-concurrency user-facing analytics. Redshift alternatives make different trade-offs. ClickHouse targets low-latency analytical serving on fresh data, Snowflake emphasi...

If you are new in the QA space, you may not really know what a bug report is. While this is a common term, many fail to dissect what it really is and what an effective bug report should really look like. In this blog we discuss everything you need to know about bug reports. A bug report is a document/ record outlining defects in a software. An effective bug report should tell a developer what went wrong, specific environment where this happened and how to reproduce this issue for further di...

Hey all, as part of our expanding challenge program we want to update and clarify some challenge requirements moving forward. First off, we want to express our gratitude for the dedication and effort you have put into your submissions. This has been one of our busiest years yet in terms of challenge participation, and it’s the enthusiasm you put into your work that makes these events a joy to run. Thank you for that! Now, onto some housekeeping. We hope the following clarifications will not o...

Why your trading losses might not be strategy failures — they could be brain mismatches I failed at trading for 18 months. Not because my strategies were bad. Because I was using a right-brain strategy with a left-brain execution style. Then I discovered neuroscience research on hemispheric dominance. Applied it to trading. Cut losses by 60% in 3 months. This is the science, the self-test, and the customized fix. The neuroscience Left brain: Logical, analytical, seque...

Low-Memory LLM Inference: Meet AirLLM As open-source Large Language Models (LLMs) continue to grow in capability, their hardware requirements have ballooned alongside them. Running a 70B or 405B parameter model traditionally demands enterprise cloud GPU servers equipped with hundreds of gigabytes of VRAM. AirLLM is an open-source Python library developed by lyogavin to make massive model inference accessible on standard consumer hardware—allowing developers to run 70B models on G...

TL;DR MCP servers are powerful, but they can expose production systems if anyone on the team can connect and run tools without guardrails. Imagine a new hire testing the app on their laptop and accidentally granting an MCP server access to the production database. Without governance, that is a realistic path to data leakage. Bifrost addresses this with three layers: Human-in-the-loop execution — Bifrost does not auto-execute tool calls. The LLM only suggests tools; your a...

Bottom line: for a beginner SaaS, put originals in object storage and have a backend worker write each thumbnail as a separate object with a deterministic key; don't make edge transformation or synchronous resize-on-upload part of the first critical path. This is the boring design, which is exactly what I want when my platform team owns the pager. It separates durable bytes from compute, lets the application ask for a known object instead of a magical transformation URL, and gives us a queue ...

Amazon just became one of only a handful of companies ever to cross a $3 trillion valuation. But the number that stopped me wasn't the market cap. It was AWS growing 37% year over year to $42.2 billion in a single quarter — its fastest pace in more than four years — and it still isn't enough. Andy Jassy's own words: even after lifting 2026 capital spending to roughly $220 billion, AWS "will still not have enough capacity to meet all the demand" this year, or next. He called 2028 deman...

Hi HN, this is Shailendra and Karan here. We are building a fast and safe way for coding agents to debug issues live in production. When prod breaks, it lets Cursor, Claude, and others drop virtual breakpoints or probes safely in your running code, and extract the exact variable values that logs don’t have. All this saves time and effort for engineers who’d otherwise dig through logs and traces or redeploy with console.logs or print statements until they find the root cause. Here is the link to ...
