Preparing for final exams is stressful enough without the tool you depend on for schoolwork suddenly going offline. That’s the situation many students across the US dealt with on Thursday. After a ransomware attack hit Instructure, the company behind Canvas, the platform switched to “maintenance mode” at the worst possible time. The hacking group ShinyHunters claimed responsibility for the breach. Experts say the disruption highlights just how far these attackers are willing to go to pressure their targets.Were you aware that Google Chrome quietly downloads the Gemini Nano AI model in the background? If not, you’re in good company. Many…

If you’ve worked with AI coding tools like GitHub Copilot, Claude Code, or Gemini CLI, you’ve likely hit this familiar snag: you explain what you need, the agent spits out clean code that compiles fine, but somehow misses the point of what you actually wanted. “Vibe-coding” gets the job done for quick experiments, but it starts to break down when you’re building production-grade software or modifying established projects. According to GitHub, the problem isn’t the AI’s coding ability — it’s how we’ve been using it. Instead of treating these agents like search engines, we should think of them as detail-oriented…

Key points:Bitcoin needs to hold above $78,000 to avoid a trend reversal and return to $80,000 as resistance.Altcoin buyers have left the scene, keeping in step with Bitcoin’s slight correction.Bitcoin (BTC) pulled back near $79,000 on Friday, but buying at lower levels pushed the price toward $80,000. The next big question on traders’ minds is whether BTC will resume its uptrend or higher levels will again attract aggressive selling from bears. CryptoQuant analyst IT Tech said in a Thursday QuickTake note that BTC needs to rally and maintain above $88,880 for a bottom to be confirmed. Until then, the $85,000 to…

The discussion sounds simple, but the underlying issue is anything but. The customer purchased servers back in 2017 and normally replaces them every five to six years. Under typical circumstances, they would have been shopping for replacements around 2022 or 2023. That’s how it would have played out in the past. Then the pandemic struck, bringing supply chain disruptions along with it. The original end-of-life announcement that would have arrived around 2023 got pushed back — to 2026 for general software updates and 2028 for security patches. That stretched the usable lifespan of that server platform to roughly a decade,…

The 85-inch TV once ruled the world of large-screen home entertainment.

Overview of adaptive parallel reasoning. Imagine a reasoning model that could independently determine when to break a problem into separate subtasks and process them in parallel, how many simultaneous threads to create, and how to manage them based on the specific challenge it faces. In this post, we take a close look at the latest developments in parallel reasoning, with a particular focus on Adaptive Parallel Reasoning.

(not so long ago) being a data scientist meant spending most of your time inside a notebook, fine-tuning hyperparameters like your career depended on it — and in many cases, it really did. Do you recall those marathon grid search sessions that stretched through the night? Or crafting feature engineering pipelines that felt more like creative expression than technical work? And that rush of pride when you managed to boost your XGBoost model’s accuracy by just 0.7%? That was the reality of a data scientist’s job back in 2019 — and it made perfect sense. If you wanted a powerful…

With the future of the Combined Federal Campaign uncertain, Democratic members of Congress are pressing the Trump administration to preserve the decades-old charitable giving initiative for federal workers. A coalition of lawmakers, spearheaded by Rep. Jamie Raskin (D-Md.), along with Sens. Chris Van Hollen (D-Md.) and Angela Alsobrooks (D-Md.), cautioned that ending the CFC would “disrupt and destabilize” thousands of nonprofit organizations that count on its support. They are calling on the Office of Personnel Management to keep the program running in 2026 and into the future. “OPM has taken several steps that weaken the CFC,” the Democrats stated in…
