Here’s how ChatGPT’s upcoming ‘Study Together’ tool could enhance learning (APK teardown)

Calvin Wankhede / Android Authority TL;DR OpenAI is working on a dedicated “Study Together” mode to help users grasp concepts better. Study Together is likely to help break down concepts into simpler terms and follow up with quizzes for more engaged learning. It is being tested with both free and paid users, suggesting non-paying users might also have access when it launches. AI tools, such as ChatGPT, have accelerated learning by making concepts much easier to find and summarize. Now, OpenA

Strategies for Fast Lexers

In this blog post I’ll explain strategies I used to make the purple garden lexer really fast. purple-garden is an s-expr based language I am currently developing for myself. Its my attempt at building a language I like, with a battery included approach, while designing it with performance in mind. This doesn’t mean all approaches are feasible for your use case, architecture and design. I tried to bring receipts for my performance claims, so watch out for these blocks at the end of chapters: I

Monitoring My Homelab, Simply

Monitoring my Homelab, Simply Date: 2025-07-09 I have a middling self-hosted/homelab setup, and it occasionally breaks. Alas, no monitoring tool has ever sparked joy in me. Don’t get me wrong, I understand that they’re essential for large fleets of services with fast-changing software and teams of oncallers working around the clock to understand the complex ways that complex systems fail… but my stuff doesn’t change that often, failures are mundane and low-scope, and I’m the only person comi

Show HN: BinaryRPC – Lightweight WebSocket-based RPC framework in modern C++

BinaryRPC 🧭 Motivation While working at my company, I had previously developed a WebSocket server prototype in Java. However, over time, we started to experience performance issues. This led me to turn to C++, a language that offers more speed and low-level system control. Through my research, I discovered that uWebSockets was one of the best options in terms of performance, so I began developing with this library. However, since uWebSockets is a very "core" library, I had to handle many deta

Samsung could take inspiration from iOS’s Live Voicemail and Pixel Call Screen (APK teardown)

Apple TL;DR Samsung is working on an on-device voicemail feature similar to iOS’s Live Voicemail. This feature would allow calls to be screened and corresponding voice messages to be stored directly on the device. Unlike Apple’s version, Samsung’s will let users customize ring time before redirecting a call, but lacks transcription functionality, at least for now. The feature was spotted within One UI 8 beta code and may initially be rolled out only in select regions. With iOS 17, Apple intr

Ruby 3.4 frozen string literals: What Rails developers need to know

Ruby 3.4 Frozen String Literals: What Rails Developers Actually Need to Know Ruby 3.4 takes the first step in a multi-version transition to frozen string literals by default. Your Rails app will continue working exactly as before, but Ruby now provides opt-in warnings to help you prepare. Here’s what you need to know. The Three-Phase Transition Plan Ruby is implementing frozen string literals gradually over three releases: Ruby 3.4 (Now): Opt-in warnings when you enable deprecation warnings

Features of D That I Love

10 features of D that I love This is a beginner-friendly post exploring some of my favourite parts of the D programming language, ranging from smaller quality of life stuff, to more major features. I won’t talk much about D’s metaprogramming in this post as that topic basically requires its own dedicated feature list, but I still want to mention that D’s metaprogramming is world class - allowing a level of flexibility & modelling power that few statically compiled languages are able to rival.

Google’s answer to Apple’s Handoff is coming with a welcome upgrade for Android (Updated)

Rita El Khoury / Android Authority TL;DR Google is working on an Android-wide “Handoff” feature for multi-device syncing. This feature will enable access to apps and media across your devices, and even sync notifications between them. Apple has a similar Continuity feature called Handoff, albeit without notification syncing. Update, July 1, 2025 (04:46 AM ET): We’ve managed to enable the UI for the Handoff feature within Cross-device services. The feature is still a work in progress and doe

Samsung is cooking up a privacy and security powerhouse in One UI 8 (APK teardown)

Joe Maring / Android Authority TL;DR Samsung seems to be developing a new “Alert Center” in One UI 8 to notify users about sneaky apps, security risks, and aging account settings. Code strings describing “Alert Center” and its features were discovered in an internal One UI 8 build. It’s unclear when Samsung will launch the new security hub, but it should be available in your phone’s Settings when and if it goes live. Samsung seems to be going one step above Android’s built-in security and pr

Chrome on Android might borrow NotebookLM’s best feature

Tushar Mehta / Android Authority TL;DR Google is testing AI audio overviews in Chrome for Android. This feature will be available as part of Chrome’s Read Aloud functionality. AI audio overviews could convert text from any webpage into interactive NotebookLM-style podcasts for improved learning. Google is steadily building up the number of touchpoints where we interact with AI by default. Search, one of Google’s most used products, has already been canopied by AI overviews for a text-based s

Here’s your first look at Google Photos’ Remix video feature for photo animations (APK teardown)

Edgar Cervantes / Android Authority TL;DR Google Photos is working on a new Remix video that could generate videos from still images. The feature includes customizable movement styles like “Subtle Movements,” “Go Wild,” and “I’m Feeling Lucky.” Remix and Remix video features are still a work-in-progress and haven’t been announced yet. We’ve previously spotted Google Photos working to incorporate generative AI to transform photos with the upcoming Remix feature. Last week, we also found code

Google Photos could soon suggest photos you may want to delete (APK teardown)

Edgar Cervantes / Android Authority TL;DR Google Photos may soon offer suggestions to help users clean up storage by deleting unnecessary photos. These suggestions will appear after users delete multiple photos. The feature will likely be optional, and the app could receive a corresponding setting to turn it off. Google Photos already offers a convenient way for users to free up storage space on their devices through the “Manage storage” option. It lists photos and videos with large file siz

Google Messages will help you shame your friends into finally turning on RCS (APK teardown)

Edgar Cervantes / Android Authority TL;DR To take full advantage of RCS messaging features, everyone in the chat needs to have RCS enabled. Google Messages is working on a feature that would prompt you to send friends without RCS a message asking them to turn it on. Messaging on Android is better than it’s ever been, and a big part of that is due to the arrival of Rich Communication Services (RCS) support. While that’s absolutely helped start pulling down some of the walls between Android and

Google Photos’ upcoming Remix feature could launch with a video upgrade (APK teardown)

Edgar Cervantes / Android Authority TL;DR Google Photos’ upcoming Remix feature, internally codenamed “Bluejay,” will likely support video editing. When it launches, the feature will use generative AI to transform videos into various styles, with options potentially including “I’m feeling lucky,” “Subtle movements,” and “Go wild.” Creating AI photos and videos is all the rage these days, but many people are using AI to remix their existing photos and videos. For instance, the Studio Ghibli tr

Nothing says an Essential Space premium tier could be in the cards in the future

In the interview, Pei describes the code we found as “zombie strings” that were left there during development. He adds that in its current form, Essential Space will remain free. However, he doesn’t rule out the possibility of a premium tier being added in the future: So I think that’s what happened, somebody got their hands on an older version of the APK and they decompiled it and saw that there [were] some strings related to charging for Essential Space. That was never in the production softw

A different take on S-expressions

SIMD-friendly algorithms for substring searching (2016)

Introduction Popular programming languages provide methods or functions which locate a substring in a given string. In C it is the function strstr , the C++ class std::string has the method find , Python's string has methods pos and index , and so on, so forth. All these APIs were designed for one-shot searches. During past decades several algorithms to solve this problem were designed, an excellent page by Christian Charras and Thierry Lecroq lists most of them (if not all). Basically these al

The fastest way to detect a vowel in a string

Austin Z. Henley Associate Teaching Professor Carnegie Mellon University [email protected] @austinzhenley github/AZHenley The fastest way to detect a vowel in a string 6/13/2025 I was nerdsniped recently: What is the best way to detect if a string has a vowel in it? This is trivial, right? But as I started getting into it, I realized there is much more to this. I challenged myself to come up with as many ways to detect a vowel as possible. I even asked a few friends to give it a go. Whi
