Google's new HiLight notification LED on the Pixel 11 Pro is nearly useless. Out of the box, the only two things it can glow for are when the phone is face down and you're interacting with Gemini, or when you get a call from a favorite contact. And even then, it can only glow one […]

A usage policy for Flock license plate reader cameras tells police not to talk about the cameras: When cops use Flock to arrest someone in Wapello County, Iowa, they don’t want them to know. A usage policy for the automated license plate reader cameras in the county tells police, in no uncertain terms, to keep them a secret: “DO NOT MENTION ALPR USAGE TO THE OCCUPANTS OF THE VEHICLE,” the policy document reads. “DO NOT MENTION ALPR USAGE IN YOUR REPORT OR COMPLAINT UNLESS ABSOLUTELY NECESSARY.” This reminds me of IMSI-catchers (Stingray was the most popular) a couple of decades ago. Police would go to even more extremes to hide their usage...

Go 1.27 landed in August 2024, and while it doesn’t introduce earth-shattering changes, it polishes the language in ways that add up. If you’re maintaining production services or building new ones, these updates can save you time and headaches. Let’s cut through the noise and focus on what actually affects your code. Performance: Faster Without Changing a Line The compiler and runtime received several under-the-hood optimizations. Benchmarks show a 3-5% speedup in typical server workloads, with some microbenchmarks hitting 10%. This isn’t magic, it’s the result of better inlining decisions and reduced memory allocation overhead. The best part? You get this for free. Just recompile your existing code with Go 1.27 and measure the difference. One standout improvement is in garbage collection. The GC now handles large heaps more efficiently, which matters if you’re running services with hundreds of gigabytes of live data. Latency spikes during GC cycles should be less pronounced, though you’ll still want to monitor this in production. Language Tweaks: Small but Useful Go 1.27 introduces a few language changes that simplify common patterns. The most notable is the addition of the new built-in function clear. It works on slices, maps, and type parameters, letting you reset collections without reallocating them. This is particularly handy for pooling or reusing buffers. For slices, clear sets all elements to their zero value and truncates the slice to length zero. For maps, it removes all entries, leaving the map empty but with the same capacity. For type parameters, it behaves based on the underlying type, useful for generic code. Another small but welcome change is the ability to use //go:linkname with methods. This was previously restricted to functions, which made certain low-level optimizations awkward. Now you can link methods directly, which is useful for writing highly optimized libraries or interfacing with C code. Tooling: Better Debugging and Dependency Manageme

Bankrupt Spirit accused of selling out workers in massive data sale to Google.

College students can get a free year of Google's AI Pro plan, something that would normally cost $200.

The launch of the new study features marks Google's latest effort to make Gemini the AI assistant that students turn to when learning and studying, as it continues to compete with companies like OpenAI.

As we're gearing up for back-to-school season, Google is rolling out a new dedicated student hub in Gemini. It's a one-stop repository for collecting research in a study notebook, creating flashcards, taking practice quizzes, and more. Google is also enhancing its study notebooks with support for graphs and images. It can even add test dates […]

Google's new Pixels make some compromises but still manage to be good phones.

The foldable phone market is in the middle of a huge transformation, but no one told Google. Last year, Samsung transformed its Galaxy Z Fold 7 with a dramatically thinner design. This year, it made its phones thinner and lighter again, almost eliminated the crease, and introduced a new passport-sized form factor that feels like […]

Google is trying to get you off your phone. The Pixel 11 Pro is "A Phone Designed to Help You Use It Less," the company promises. It can proactively help you book restaurant reservations, take the best frames from a video, and help you voice-text significantly faster. The pitch is that the new features bundled […]

Hello again! Weeks 9 and 10 covered the fourth estimator family, the first release that carries my work, and a git mess that taught me more than the code did. PR #1920 merged, and sbi 0.27 shipped First, the ratio estimator builder from my last post made it in, together with the whole base class hardening bundle. Right after that, sbi 0.27 was released and PRs 1 to 5 were ported over to main . So the typed builder API is now actually in a release, for NPE, NLE, MNPE, MNLE and all four NRE variants. That also means the free rename window is closed. The z_score_input and z_score_condition names we picked in week 7 are now the shipped names, which is exactly why we did that rename when we did. Writing the design before the code Under the new workflow I described last time, the vector field work started with a markdown file instead of a Python file. The vector field family is genuinely harder than the others. build_vector_field_estimator picks along what looks like three axes at the same time: whether you want flow matching or score matching, which SDE type you want if it is score matching, and which network architecture sits inside. And unlike every other family, there are no per-model build functions to hang a config class on. I wrote up the options with some open questions then my mentor, Jan reviewed it and we settled on one builder with a base class abstraction to cut the redundancy across builders. Doing this on paper first was clearly the right call. Some of the things I had assumed while writing the proposal turned out to be wrong, and finding that out in a review comment on a markdown file was a lot cheaper than finding it out in a review comment on 800 lines of code. PR #1921 : VectorFieldEstimatorBuilder With the design agreed, the implementation covers FMPE and NPSE. The builder takes the architecture as model , one of mlp , ada_mlp , transformer or transformer_cross_attn , plus estimator_type for flow versus score and sde_type for the noise schedule. One de

The European Commission’s 2022 procurement for a participatory foresight study on next-generation online platforms placed platform design and consumer behaviour within a wider policy question: how could the platform economy evolve, and what might those changes mean for European Union policymaking? The work was not a narrow experiment on marketplace user experience. Instead, it was a two-year exercise intended to identify long-term trends across online platforms and assess their policy implications. The Commission published the call, reference CNECT/2022/OP/0049 , in August 2022. Its official announcement of the foresight study on the future of online platforms lists a submission deadline of 22 September 2022 at 16:00 CEST . That makes the procurement a completed historical call, rather than a current tender opportunity. The framing remains relevant because interface design, recommendation systems and other platform choices can influence what people notice, compare and select online. But the Commission’s stated objective was broader than any one marketplace design question. It sought a structured view of the platform economy’s possible future trajectories and the public-policy issues those trajectories could raise. What the 2022 study was designed to examine The Commission described the project as a two-year participatory foresight study . Participatory foresight brings relevant groups into a structured exploration of future developments rather than attempting to predict one fixed outcome. In this case, the study was designed to identify ten topics in collaboration with Commission services, then examine long-term trends and their potential policy relevance. Design’s influence on consumer behaviour was part of the broader theme, not the full scope of the procurement. That distinction matters. A study focused solely on a marketplace interface might measure how a particular ranking, default or layout affects a defined consumer decision. The Commission’s foresight work i

In my last post I wrote about an error that cost me a full evening: my pom.xml had the MongoDB starter, but my code was still full of JPA annotations. The compiler kept saying cannot find symbol: class Entity . That post was about the error. This post is about the fix — every single line I had to change to move my Task Manager project from MySQL to MongoDB. If you are planning the same switch, this is the checklist I wish I had. 1. The dependency Before (MySQL + JPA): <dependency> <groupId> org.springframework.boot </groupId> <artifactId> spring-boot-starter-data-jpa </artifactId> </dependency> <dependency> <groupId> com.mysql </groupId> <artifactId> mysql-connector-j </artifactId> <scope> runtime </scope> </dependency> After (MongoDB): <dependency> <groupId> org.springframework.boot </groupId> <artifactId> spring-boot-starter-data-mongodb </artifactId> </dependency> One starter replaces two dependencies. And this is exactly where my problem started — I added the new one but never removed the old one, so half my code still compiled and half did not. Remove the JPA starter completely. If you leave it in, the jakarta.persistence annotations still resolve, and you will not notice you are mixing two worlds until something breaks at runtime. 2. application.properties Before: spring.datasource.url = jdbc:mysql://localhost:3306/taskmanager spring.datasource.username = root spring.datasource.password = yourpassword spring.jpa.hibernate.ddl-auto = update spring.jpa.show-sql = true After: spring.data.mongodb.uri = mongodb://localhost:27017/taskmanager Five lines became one. No ddl-auto because MongoDB has no schema to create. No dialect because there is no SQL being generated. The database and the collection are created automatically the first time you insert a document. 3. The model class This is where most of the work was. Here is my actual Task class after the migration: package com.taskmanager.task_manager ; import com.fasterxml.jackson.annotation.JsonIgnore ; import org.

I built HermitMQ entirely in Go. The main feature is ditching heavy wrappers like JSON in favor of a custom 29 byte binary protocol. Additionally, data transmission over the network uses a direct file to socket copy mechanism. I will go into detail about the architecture, data storage approaches, benchmark numbers, and show how it is implemented in code. The full source code for the HermitMQ project is available on GitHub: https://github.com/ekhidirov/hermitmq The problem with standard brokers and the cost of serialization When the message counter exceeds hundreds of thousands per second, the main problem for a Go developer is the garbage collector. If every message is parsed via standard JSON, the application starts allocating a massive number of small objects in memory. The GC wakes up too frequently, eating up CPU time and causing network latency spikes. To avoid triggering the garbage collector at every turn, I completely abandoned standard serialization libraries. Every message is packed into a custom header of exactly 29 bytes. In code, the message structure looks extremely simple: type Message struct { Magic byte Timestamp uint64 Offset uint64 KeySize uint32 PayloadSize uint32 RecordCount uint32 Key [] byte Payload [] byte } The first byte is a magic number for version checking and instantly discarding bad packets. Next come 8 bytes for the timestamp in nanoseconds and 8 bytes for the offset, which the broker fills in itself to maintain message order. Then come the key and payload sizes, 4 bytes each. Finally, 4 bytes are reserved for the record count to support batching. The broker reads the stream using the binary package and reuses buffers via sync.Pool. As a result, under standard loads, we achieve practically zero memory allocation. Being honest about allocations and plans for zero serialization To be completely honest: although the broker is incredibly frugal under standard loads, a memory management compromise still remains. An absolute victory over al
