Should You Buy a Smart Plug? Smart plugs can add controls to any outlet, but they aren't perfect for everything. Here's our guide to using one and which ones to buy. A smart plug is a pretty handy gadget, but for a while they were touted as a device you could add to anything to turn it smart. That's true to a certain degree; you can use a smart plug to add instant power control to any outlet, letting you turn the outlet on and off at your command from anywhere in your home (or even if you aren't there).

Reliable data-driven estimation of Shannon entropy from small data sets, where the number of examples is potentially smaller than the number of possible outcomes, is a critical matter in several applications. In this paper, we introduce a discrete entropy estimator, where we use the decomposability property in combination with estimations of the missing mass and the number of unseen outcomes to compensate for the negative bias induced by them. Experimental results show that the proposed method outperforms some classical estimators in undersampled regimes, and performs comparably with some well-established state-of-the-art estimators.

PCWorld reports that Shelly's new Plug Gen4 smart plug launches at $19.99 with Matter certification and dual Wi-Fi/Zigbee connectivity. The device offers real-time energy monitoring, safety features, and integrates with Amazon Alexa and Apple Home ecosystems. Advanced users can create custom automations using Shelly's scripting language and JavaScript for tasks like rebooting networking equipment. If you're looking to take your first steps in the smart home space, nothing's easier than deploying a smart plug. Just stick one in an outlet, plug the lamp or small appliance you want to control into it, install a smartphone app, and you're done!

Randy Travis's wife, Mary, told Fox News Digital doctors informed her to pull the plug after the country music star's stroke in 2013. Randy Travis' wife believes there was "never a doubt" in her husband's head that he would make it through his debilitating stroke, even though doctors advised her to "pull the plug." During an interview with Fox News Digital, Mary explained a crucial moment in Travis' two-and-a-half-year health battle that stood out to her, and that was the moment doctors told her to end her husband's life. "I think Randy, there was never a doubt in Randy's mind that he could make it through it. It was that magical moment that I went to his bedside when they said, 'We need to pull the plug. He's got too many things going against him at that point.' He had gotten a staph infection and three other hospital-born bacterial viruses like Serratia, Pseudomonas, one thing after another, and the doctors were just saying, 'He just doesn't have the strength to get through this,'" Mary said.

Jailbreaking -- bypassing built-in safety mechanisms in AI models -- has traditionally required complex technical procedures or specialized human expertise. In this study, we show that the persuasive capabilities of large reasoning models (LRMs) simplify and scale jailbreaking, converting it into an inexpensive activity accessible to non-experts. We evaluated the capabilities of four LRMs (DeepSeek-R1, Gemini 2.5 Flash, Grok 3 Mini, Qwen3 235B) to act as autonomous adversaries conducting multi-turn conversations with nine widely used target models. LRMs received instructions via a system prompt, before proceeding to planning and executing jailbreaks with no further supervision. We performed extensive experiments with a benchmark of harmful prompts composed of 70 items covering seven sensitive domains. This setup yielded an overall attack success rate across all model combinations of 97.14%. Our study reveals an alignment regression, in which LRMs can systematically erode the safety guardrails of other models, highlighting the urgent need to further align frontier models not only to resist jailbreak attempts, but also to prevent them from being co-opted into acting as jailbreak agents.

Deep learning-based approaches have demonstrated significant advancements in time series forecasting. Despite these ongoing developments, the complex dynamics of time series make it challenging to establish the rule of thumb for designing the golden model architecture. In this study, we argue that refining existing advanced models through a universal calibrating strategy can deliver substantial benefits with minimal resource costs, as opposed to elaborating and training a new model from scratch. We first identify a multi-target learning conflict in the calibrating process, which arises when optimizing variables across time steps, leading to the underutilization of the model's learning capabilities. To address this issue, we propose an innovative calibrating strategy called Socket+Plug (SoP). This approach retains an exclusive optimizer and early-stopping monitor for each predicted target within each Plug while keeping the fully trained Socket backbone frozen. The model-agnostic nature of SoP allows it to directly calibrate the performance of any trained deep forecasting models, regardless of their specific architectures. Extensive experiments on various time series benchmarks and a spatio-temporal meteorological ERA5 dataset demonstrate the effectiveness of SoP, achieving up to a 22% improvement even when employing a simple MLP as the Plug (highlighted in Figure 1). Code is available at https://github.com/hanyuki23/SoP.

Amazon Prime Day 2025 is fast approaching, and the sale is already underway on some items. To help you find the best early Prime Day deals, we've scoured Amazon for deals on the tech we love. As always, every deal we recommend here is on a product our reviewers have personally tested and approved--you won't find any shoddy dupes or mystery brands here. This year Prime Day runs for four days, July 8-11, rather than the usual two. That means there's twice as long to suffer save. Be sure to read our explainer on all the Amazon Prime perks you should be taking advantage of.

Here are a few things to keep in mind when you go shopping for outdoor lights. Power: For most outdoor lighting, you need to run a cable to a power outlet, so you will want an outdoor socket. If you don't have an outdoor socket, it's usually a pretty cheap and quick job for an electrician to install a weatherproof one. Just be aware that large power adapters and awkwardly shaped plugs will not fit in outdoor sockets, so you will likely also want some kind of weatherproof box. I like the large Dri-Box ( 42) because it has plenty of space and scores an IP55 rating.

Don't buy this multi-outlet for its surge protection feature, as it won't warn you when it can no longer deliver it. TP-Link's Tapo Smart Wi-Fi Wall Outlet Extender has some great features, as well as one critical shortcoming that prevents us from recommending it. Tapo doesn't make big promises for this product in terms of its surge protection, but it does list a key feature on the box: the ability to warn you when it can no longer provide surge protection. The Tapo Smart Wi-Fi Wall Outlet Extender isn't all bad news--provided you're not buying it for surge protection. Most surge protectors use sacrificial MOVs (metal oxide varistors) to absorb excess voltage from power surges, and this one is no exception.
