Google is giving its AI note-taking app a new name. The company announced on Thursday that NotebookLM is becoming Gemini Notebook, but will remain a standalone app even as it integrates more deeply across Gemini and Google Search. Google first revealed Gemini Notebook - then called Project Tailwind - in May 2023 before widely releasing […]

Google said users can soon access their notebooks through AI Mode in Search.

With this new update, Google is expanding AI Mode beyond answering questions and into completing tasks across the apps they use regularly.

Daniel Solove argues in the Wall Street Journal (alternate link ) that giving people control of their personal data is not an effective way to regulate privacy in this era. Instead, we need to hold companies accountable for their actions, similar to what we do with food and drug companies. Measures such as rigorous data minimization, fiduciary duties, liability for negligent or reckless technological design, liability for algorithms that cause harm, and multi-stakeholder review of technologies will be far more effective.

Bluetooth and Wi-Fi work in tandem to power the wireless Android Auto experience.

Google has been ordered by the EU to open up key Android handset features to rival AI voice assistants.

Google must give rival AI assistants and search engines greater access to key parts of Android and Google Search after the European Union ordered the company to comply with the bloc's digital antitrust rules. The two decisions, handed down Thursday, could weaken Google's control over two of the tech industry's most important platforms and have […]

Gone are the hours of careful thought and planning that go into coding a new feature. Vibe coding is too risky though, so another Driven Development was created. I'm referring to SDD (Spec Driven Development) of course. The vibe coding approach is great for prototypes and throwaway code, but this way of working falls apart when teams realise that the code needs to be maintained. So the thing that helps fix this is SDD. Create a spec once from clear technical specs and then generate some high quality code. Sounds great, right. Reminds me of IaC, where you use a templating language to create infrastructure. Software as Code maybe. SaC anyone? Unfortunately, in practice it's not that straightforward. Thoughtworks have placed SDD into an "Assess" category and warned that it could be an anti-pattern for releasing software. Deterministic vs Probabilistic This article isn't about SDD. I'm more interested in discussing the output of SDD and how that is tested. Code can now be generated fast these days. So what better to test AI-written code than with AI itself. There are a lot of concepts and technical terms for the Quality Assurance part of AI generated code. One of these is the LLM-as-a-Judge idea. This idea is used to score the output of an LLM based on some explicit criteria. Traditionally, the way to evaluate an LLM was to judge its output on the helpfulness or faithfulness (using something called "exact-match" metrics). Sometimes it was usually down to a human to do this. It also changes the way that Quality is Assured when dealing with AI-written code. Traditional QA is built on deterministic checks; either something does or does not fail. Something like expect(x).toContainText(y); . A failing test means that something is wrong. Then the bug can be fixed in the code and the test will pass. However, the outputs of an LLM are probabilistic , so it breaks the traditional pass/fail model. This is where a judge comes in. Instead of pass/fail, it can assign a score based o

Submission for DEV's Summer Bug Smash — Clear the Lineup track. The codebase a2a-benchmark is my multi-language A2A (Agent-to-Agent) performance suite: four agents — Python and Go behind Gemini tool-calling via ADK, Node.js and Rust as direct handlers — each compute Mersenne primes with the Lucas–Lehmer test, while a harness sweeps N=1–24 and charts calculation time and round-trip time. The committed results stopped at N=22. I never questioned that. I should have. The headline bug: a whole column of data didn't exist CPython 3.11+ limits int→str conversion to 4,300 digits by default (a DoS mitigation). My Python agent stringified each prime it found: mersenne_primes . append ( str (( 1 << p ) - 1 )) The 24th Mersenne exponent is p=19937, and 2^19937−1 has 6,002 digits . So for any request of 24+ primes, the tool raised ValueError — and the A2A response dutifully delivered the stack-trace text instead of a result: "text": "Exceeds the limit (4300 digits) for integer string conversion; use sys.set_int_max_str_digits() to increase the limit" The benchmark's Python column was structurally incapable of producing data at N≥24. The kicker: the stringified list was never used . The tool returns only elapsed_time . The fix is deleting the str() — which also removes formatting work from the timed region that the Node and Rust agents never paid (Go had the same dead val.String() call). Fix: PR #1 — plus a switch from time.time() (wall clock, non-monotonic) to time.perf_counter() , and a regression test at count=24. Before/after, N=24 row: Node.js Rust Go Python before 1633.01 ms 812.57 ms 1451.49 ms N/A (crash) after 1616.13 ms 824.10 ms 1531.10 ms 2425.9 ms The harness was reading its data from LLM prose The Python agent's timing came back in two places: a structured elapsed_time in the tool artifact, and the model's prose. The harness regexed the prose first : m = re . search ( r " It took ([\d\.\-e]+) seconds " , text ) In live runs, Gemini said "Calculating the first 5 Mer

Intuition Manacher's Algorithm leverages the symmetry of palindromes to avoid redundant comparisons. Instead of treating odd- and even-length palindromes separately, the input string is transformed by inserting a special character (#) between every character and adding sentinel characters (^ and $) at both ends. This allows every palindrome to be treated as an odd-length palindrome. While traversing the transformed string, the algorithm maintains the center and right boundary of the rightmost palindrome found so far. For each position, it uses the palindrome information from its mirror position (with respect to the current center) to initialize the palindrome radius, significantly reducing unnecessary expansions. Only when the palindrome reaches beyond the current right boundary is additional expansion performed. This optimization ensures that every character is expanded at most a constant number of times, resulting in linear time complexity. Approach Handle the edge case by returning an empty string if the input string is empty. Transform the input string by inserting # between every character and adding sentinel characters (^ and $) at both ends to treat odd- and even-length palindromes uniformly. Create a palindrome radius array p, where p[i] stores the radius of the palindrome centered at index i in the transformed string. Initialize the variables center and right to represent the center and right boundary of the current rightmost palindrome. Initialize max_len and center_index to keep track of the longest palindrome found during traversal. Traverse the transformed string from left to right, ignoring the sentinel characters. Compute the mirror index of the current position using the current palindrome's center. If the current index lies within the current right boundary, initialize its palindrome radius using the previously computed mirror information. Expand around the current center while the characters on both sides are equal, increasing the palindrome radius

Google's biggest solar and battery project stands in sharp contrast with xAI's nearby unpermitted power plant.

With the settlement withdrawn, Google is now bound by the court's full antitrust remedies.

Eco-friendly routes on Google Maps are worth checking out, but there are a few things to know before you do.

Amazing : Researchers from ETH Zurich in Switzerland, however, managed to create a new type of pixel that can simultaneously do both. This hypercharged pixel, called a Fourier pixel, can generate and sense arbitrary light fields and tap into a pixel’s full potential for carrying information by manipulating light’s intensity, oscillation phases, and polarization. The team reported its findings in a paper published yesterday in Nature. We are one step closer to 1984 technology: The telescreen received and transmitted simultaneously. Any sound that Winston made, above the level of a very low whisper, would be picked up by it; moreover, so long as he remained within the field of vision which the metal plaque commanded, he could be seen as well as heard. There was of course no way of knowing whether you were being watched at any given moment...

Third-party app stores are coming to Android on July 22.

There’s now only one worth buying—but you can still access new features on older models you might already own.

Cartography is all about taking the real world and turning it into a picture that people can understand. It’s the process of deciding: what places to show, what details to keep or remove, what colors and symbols to use, how to draw the round Earth on a flat screen or paper Cartography mixes geography (knowing where things are), design (making the map clear and beautiful), and math (flattening the Earth using projections). Every map you see—Google Maps, airport maps, weather maps, D3.js visualizations—is a result of cartography. Line simplification alogorithms are tools used in cartography to reduce the number of points in a geographic shape while keeping the shape recognizable. 🌍 Why do we need line simplification? Real geographic shapes—coastlines, borders, rivers, airport boundaries—are extremely detailed. If you zoom in enough, you can always find more bumps, curves, and tiny wiggles. This is what Lewis Fry Richardson discovered: The more precisely you measure a coastline, the longer it becomes.Because coastlines have infinite detail.But your computer screen does not have infinite detail. It has pixels. If you try to draw a super-detailed coastline - the file becomes huge > the map loads slowly > D3.js rendering becomes slow > zooming becomes laggy > the map looks messy when zoomed out. This is why we need line simplification algorithms. 🎯 What do line simplification algorithms do? They remove unnecessary points from a shape while keeping the overall form. Think of it like: drawing a coastline with fewer squiggles. smoothing a jagged boundary reducing a 10,000‑point shape to 1,000 points. making the map faster and cleaner. The goal is: Keep the important shape, remove the tiny details. 🧩 Why this matters for zoomable maps Zoomable maps (like D3 zoom or Leaflet zoom) need multiple resolutions: When zoomed out → simple shapes When zoomed in → detailed shapes If you use only high‑resolution data: the map becomes slow, too many points are drawn, the user sees clutter

Epic Games and Google have just jointly withdrawn their attempt to retroactively settle the lawsuit that's changing how Android app stores work in the United States - and that means Google will be forced to carry rival app stores inside of its own. In fact, Google tells the court, it's ready to begin carrying third-party […]
