Hello everyone, I've been working on a PyTorch library for solving Differential Algebraic Equations (DAEs) that supports vectorized execution and GPU acceleration. The library implements several algorithms that are not currently available in the Python ecosystem, including Generalized-Alpha integration, Dummy Derivatives index reduction, and adjoint sensitivity methods for DAEs. My motivation was to enable differentiable DAE simulation workflows in PyTorch for applications such as system identification, scientific machine learning, and physics-informed modeling. I'd be very interested in feedback on the numerical methods, API design, and potential ML use cases. GitHub: https://github.com/yousef-rafat/torchdae submitted by /u/Otaku_7nfy [link] [留言]

This is not about the money. It’s about the principle. ​We are constantly told that AI is here to "help" us, but multi-million dollar companies like Perplexity are weaponizing their own AI to steal from regular users, stonewall our complaints, and blatantly violate consumer rights. It is systemic corporate greed, and they are getting away with it because people are too exhausted to fight back against a machine. ​Well, I am fighting back, and you should too. Here is the absolute scam Perplexity is running right now. ​ How they steal your money: ​Living in Latvia, I pay for my Education Pro subscription in Euros (equivalent to $10/month). ​April 27: A payment was due, but my card declined. Fair enough. Perplexity froze my account immediately. I had ZERO access to Pro features. ​May 16: I manually paid for my subscription to reactivate it. The payment cleared. ​May 29: Barely 13 days later, my account was stripped of its Pro status and locked again. ​When I demanded an explanation, their billing system's "logic" was revealed: They took my May 16 payment and retroactively applied it to the "past due" period of April 27 - May 16. A period where my account was completely frozen and the service was actively withheld. ​They effectively charged me for a full month of service, gave me 13 days of access, and pocketed the rest. This isn’t a glitch; it’s unjust enrichment. It is theft. ​Enter "Sam" the AI ​If you try to get your money back, you don't get a human. You get "Sam, the AI Support Agent." ​I tried to explain that under European law, you cannot charge a customer for digital services you didn't provide. Sam’s response? A pre-programmed loop denying my refund, claiming I was "outside the 14-day EU refund window." ​Here is the most infuriating part: I did submit a ticket well within that window. But their automated system closed it without resolving it. When I pointed this out, the AI literally replied: "I don't have access to separate ticket histories." ​They use their o

CAP Theorem Explained: Choosing Between Consistency, Availability, and Partition Tolerance in Databases Imagine you're trying to book a flight online, and just as you're about to pay, the website crashes. When you try to book again, you find that the flight is now sold out, even though the website initially showed available seats. This frustrating experience is a classic example of a database trade-off between consistency, availability, and partition tolerance. The CAP theorem, first introduced by Eric Brewer in 2000, states that it's impossible for a distributed data store to simultaneously guarantee more than two out of these three principles. In this post, we'll delve into the world of CAP theorem, exploring its fundamentals, real-world database examples, and design implications. Introduction to CAP Theorem Understanding the Basics of CAP Theorem The CAP theorem is based on three primary principles: Consistency : Every read operation will see the most recent write or an error. Availability : Every request receives a response, without guarantee that it contains the most recent version of the information. Partition Tolerance : The system continues to function and make progress even when network partitions (i.e., splits or failures) occur. Importance of CAP Theorem in Distributed Systems In distributed systems, where data is spread across multiple nodes, the CAP theorem plays a crucial role in understanding the trade-offs between these principles. By grasping the CAP theorem, developers can design more resilient and scalable databases that meet the specific needs of their applications. Brief Overview of the Blog Post This post will explore the CAP theorem in depth, using real-world database examples to illustrate the trade-offs between consistency, availability, and partition tolerance. We'll discuss the fundamentals of CAP theorem, examine CA, CP, and AP systems, and provide guidance on designing for each combination. By the end of this post, you'll have a solid un

At GTC 2026, Jensen Huang said something that made a lot of people pause: the PC is being reinvented. He and Microsoft launched RTX Spark with the N1X chip, cramming petaflop-level AI compute into a desktop form factor. On the surface it looks like another hardware upgrade, but this time the use case is genuinely different. Previous PC performance gains served humans: faster rendering, faster compiling, smoother gaming. This round of compute improvement is largely aimed at AI agents. Agents need to run vision-language models locally, understand screen content in real time, and execute GUI operations. These workloads demand sustained compute resources with a load profile completely different from human computer use. Agents Need Different Hardware Than Humans Humans use computers in bursts: typing, clicking, waiting for responses. The load is pulsed. Agents use computers continuously: constantly capturing screenshots, interpreting the display, making decisions, executing operations. The load is steady-state. This means agents need memory bandwidth and energy efficiency more than peak compute. This explains why Apple's M-series chips perform well in on-device AI scenarios. The unified memory architecture lets GPU and CPU share the same memory pool without data transfers between them, which is highly efficient for model inference that frequently accesses large parameter sets. M-series energy efficiency also suits long-running agent workloads without thermal throttling. NVIDIA's RTX Spark takes another path: more GPU compute and more memory (128GB unified) to handle on-device AI demands. The N1X chip has higher total compute than M-series, better suited for heavy workloads. Different tradeoffs, same destination: AI agents running on the device in front of you. There's Already a Complete Agent Stack on Mac What's worth noting is that the on-device AI agent stack on Apple's ecosystem is already fairly complete. M-series chips at the hardware layer. MLX at the framework lay

StudyQuiz has moved forward since the first frontend MVP release. This update focuses less on adding major new features and more on making the app smoother to use, safer to change, and more reliable in production. What’s New Logout functionality Call-to-action section on the user dashboard Edit and delete functionality for questions and answers Guest Mode restrictions for editing and deleting questions and answers Integration tests for core backend workflows Improved Enhanced quiz user experience and feedback Improved quiz creation user experience Improved navigation across the application More reliable page reload behavior for protected routes Fixed Fixed 500 errors when reloading protected frontend pages Fixed production database session configuration issues Improved reliability around authentication-protected routes Why This Release Matters This release is mainly about stability and maintainability. I added integration tests and a GitHub Actions workflow so future changes are checked automatically before they silently break existing behaviour. StudyQuiz now feels closer to a maintainable product rather than just a working prototype. Coming Next The next major focus is slide upload and AI-assisted quiz generation, allowing users to generate structured quizzes more directly from their study materials.

Today I started Week 3 of the Machine Learning Specialization and learned about Classification. Until now, most of my learning focused on regression, where models predict numerical values. Today I discovered that many real-world problems involve predicting categories instead. Some examples include: Detecting spam emails Predicting whether a customer will leave or stay Identifying whether a tumor is malignant or benign I also learned about Logistic Regression. Despite its name, it is used for classification tasks. The model predicts probabilities that help determine which class an example belongs to. Another important concept was the Decision Boundary, which is used to separate different classes based on predicted probabilities. To reinforce my understanding, I completed the graded assignment for this section. This week feels like an important step because classification is widely used in real-world machine learning applications. 🚀 Looking forward to learning more about classification models and improving my understanding of machine learning.

Two Hypotheses In the contemporary discussion about artificial intelligence, two distinct hypotheses intersect and are often conflated. The first hypothesis describes AI as a thin client between intention and result. Historically, a chain of translators existed between a concept and an artifact. A person formulated a task for a programmer, the programmer wrote code, the code became a program. A screenwriter passed an idea to a studio, the studio hired a VFX team, the team produced a film. A composer worked with musicians and a studio to record a track. AI shortens this chain, allowing a result to be obtained directly from a natural language prompt. The second hypothesis is more radical. It asserts that AI washes out not only performers but also apprentices. The main function of many professions was not the production of the current result, but the reproduction of knowledge. A junior was needed not because he is useful today, but because in five years he will become a senior. A student was needed not to create value now, but to become an engineer. A doctoral candidate was needed not for brilliant papers, but to undergo the school of scientific thinking. The Destruction of the Apprenticeship Mechanism The classical model of competence growth was built on review. A junior wrote code, a senior dissected it, extracted the substrate of experience, and transmitted professional intuition. Each review was an act of knowledge transfer. The new model looks different. A person formulates a prompt, AI generates the result. If code of acceptable quality appears immediately, the economic need for a junior declines. Along with it, the mechanism through which knowledge was transmitted disappears. A structural question arises that goes beyond the labor market. Where will the next seniors come from if the intermediate link does not undergo the path of learning through mistakes and reviews. This is a problem of competence reproduction, not simply automation. The Transformation of Educa

After migrating Spark pipelines to Azure Kubernetes Service, two infrastructure settings interacted destructively: spark.kubernetes.local.dirs.tmpfs=true backed shuffle spill with RAM instead of disk, and a hard podAffinity rule forced all executors onto one node. Together, they caused repeated OOM kills invisible to standard diagnostics. By Pranav Bhasker

MiniMax released M3 today and the API is already live. Worth separating what comes from their own official model page versus what comes from the launch announcement, because some of the numbers are sourced differently. From the official model page: BrowseComp 83.5, ahead of Claude Opus 4.7 at 79.3. PostTrainBench 37.1, which ranks third behind Opus 4.7 at 42.4 and GPT-5.5 at 39.3. From the launch announcement: SWE-Bench Pro 59.0%, Terminal Bench 2.1 66.0%, MCP Atlas 74.2%. The headline "beats Opus" is BrowseComp-specific, not a general capability claim across all dimensions. The context window is up to 1M tokens, implemented through their in-house MiniMax Sparse Attention architecture. They state 512K as the guaranteed minimum with 1M as the ceiling. The model was trained on 100T+ tokens and is natively multimodal rather than vision being added after the fact. Open-weights release is coming to HuggingFace and GitHub but listed as "coming soon." API access is available now through several paths, including OpenAI-compatible endpoints, while the weights are still pending. The model also supports native MCP tooling, which is where the 74.2% MCP Atlas number comes from. The demo claims are the part worth being skeptical about. A 12-hour autonomous ICLR paper replication run and a CUDA kernel optimization loop reaching 9.4x speedup are impressive if real, but these are curated showcase demos that are hard to evaluate from a screenshot. Whether sparse attention holds up at 900K+ tokens in practice rather than in controlled benchmarks is an open question. submitted by /u/Drysetcat [link] [留言]
