If youβre a Bluetooth system engineer working with AOSP, you already know debugging can get messy. Connections drop, profiles misbehave, and sometimes nothing seems to add up. In those moments, the dumpsys tool should be the first thing you reach for. And when it comes to Bluetooth, no command is more useful than adb shell dumpsys bluetooth_manager. This single command can reveal a wealth of information about the state...

Developing Low-Cost AI-Based Similarity Search
The world of artificial intelligence (AI) and large language models (LLMs) often conjures images of immense computing power, proprietary platforms, and colossal GPU clusters. This perception can create a high barrier to entry, discouraging curious developers from exploring the fundamentals. I recently embarked on a project β a sophisticated yet simple AI-powered chatbot I call the Wiki Navigator β that proves this...
7 AWS Services Every Data Engineer Should Master
If you work in data engineering, you know the job is a constant balance between speed, reliability, and maintainability. It is not enough to just move data from one system to another. You must make sure the process will still work next month, that it can handle more volume next year, and that someone else can understand it without asking you a hundred questions. I have been through years of building ETL jobs, chasing...
Guardrails for AI: Protecting Privacy in Both Prompts and Responses
Large language models (LLMs) like OpenAIβs ChatGPT, Anthropicβs Claude, Googleβs Gemini, or Metaβs Llama have taken the world by storm, offering powerful text-generation capabilities for everything from coding help to customer service.

A Primer on Memory Consistency and Cache Coherence, Second Edition
I've been trying to learn about different memory consistency models more rigorously and found this book to be a nice introduction so far (I'm only on the fourth chapter, though). As an aside, I've been happy to see that a lot of my intuition regarding mathematical formulations of transaction isolation levels in databases has carried over to make this an easier read than it would otherwise be. The parts I've read have...

Replacing Input Specifications for AI Coding with Visual Programming Diagrams
The problem of AI code generation is that it is very difficult to prepare complete and precise input specifications, especially in case of a large project. Visual programming can play the role of dynamic specifications: user can visually modify workflow rather than sending requests to AI code re-generation whenever spec is getting changed. submitted by /u/PurpleDragon99 [link] [comments]

C3 Language 0.7.6 adds generic inference and shebang compatibility
This release adds shebang support, and simple generic parameter inference (which doesn't have that much use in C3 compared to languages that have per function/type generics, rather than generic modules). There are some conveniences, like in-place compile time concat with +++=. And of course that slices and arrays of types with an implemented == overload can now be compared as well. There are plenty of fixes, but still...

In-depth Quake 3 Netcode breakdown by tariq10x
A very good breakdown about how quake 3 networking worked so well on low bandwidth internet back in the days. Even though in my opinion, Counter-Strike (Half-Life) had the best online multiplayer during the early 2000s, due to their lag compensation feature (server side rewinding), which they introduced I think few years after q3 came out. And yes, I know that Half-Life is based on the quake engine. submitted by...
The "Phantom Author" in our codebases: Why AI-generated code is a ticking time bomb for quality.
I just had a code review that left me genuinely worried about the state of our industry currently. My peer's solution looked good on paper Java 21, CompletableFuture for concurrency, all the stuff you need basically. But when I asked about specific design choices, resilience, or why certain Java standards were bypassed, the answer was basically, "Copilot put it there." It wasn't just vague; the code itself had subtle,...
psudoFont Liga Mono: A programming font with ligatures!
psudoFont Liga Mono: a font with ligatures made for programming! I call it an itch, when I have one I idea that at first seems farfetched so I let it be, but then the itch starts to grow and it doesn't disappear until I do something about it. The process of creating my own font family was quite similar to how I created Nebula Oni Theme, a color theme for VSCode. It's the color theme that I used to render some of the...
Dissecting ConfigureAwait in C#
A nice video about ConfigureAwait in C#. One thing I didn't know is that ConfigureAwait(false) also affects a custom task scheduler, and, for instance, this is the reason why you should never use ConfigureAwait(false) with Orleans, because it'll break their threading model. submitted by /u/Emergency-Level4225 [link] [comments]

Implementing memory-augmented majorization with an OR gate for transitions
I implemented a system that explores integer partition space (N=20, 627 partitions via majorization lattices) while accumulating memory as 4D echo vectors from transition history. The core mechanism is an OR gate for transitions: Ξ» α΅£ ΞΌ (Ξ» ΞΌ) (C(Ξ»,ΞΌ) Ο) A transition happens if: classically allowed by majorization OR memory coherence is sufficient (Ο=0.6). The implementation includes: - Memory accumulation (echo...
