--Software requirements expressed in natural language (NL) frequently suffer from verbosity, ambiguity, and inconsistency. This creates a range of challenges, including selecting an appropriate architecture for a system and assessing different architectural alternatives. Relying on human expertise to accomplish the task of mapping NL requirements to architecture is time-consuming and error-prone. This paper proposes ARLO, an approach that automates this task by leveraging (1) a set of NL requirements for a system, (2) an existing standard that specifies architecturally relevant software quality attributes, and (3) a readily available Large Language Model (LLM). Specifically, ARLO determines the subset of NL requirements for a given system that is architecturally relevant and maps that subset to a tailorable matrix of architectural choices. ARLO applies integer linear programming on the architectural-choice matrix to determine the optimal architecture for the current requirements. We demonstrate ARLO's efficacy using a set of real-world examples. We highlight ARLO's ability (1) to trace the selected architectural choices to the requirements and (2) to isolate NL requirements that exert a particular influence on a system's architecture. This allows the identification, comparative assessment, and exploration of alternative architectural choices based on the requirements and constraints expressed therein. I NTRODUCTION Software systems are ever-evolving, with increases in size and complexity that call for careful elicitation of requirements and architectural choices [1]. While it has been long recognized that requirements and architecture co-evolve [2], [3], understanding their interactions, especially early in the software development process, is still an open challenge. More specifically, there is a scarcity of knowledge regarding their alignment, architecture-to-requirements traceability, and conserving architectural knowledge [4]. Most software requirements are still captured using natural language (NL) [5]-[7]. The informal nature of NLs is a significant obstacle in machine processing of such requirements [8]. In the past, researchers have proposed approaches to classify the NL requirements into different categories of functional and non-functional requirements [5], [6], to identify quality attributes from NL requirements, to facilitate architectural decisions by leveraging machine learning [7], and so on. While promising, these approaches require large, curated datasets and high model-building effort [9]. Translating NL requirements to architecture-related design decisions is a cumbersome task that has long been recognized in the research community [1].

If you're looking to protect your home with a video doorbell, I can't recommend it enough. My own video doorbell is the one purchase I'll never regret making, as it helps deter would-be porch pirates by sending motion alerts to my phone. Fortunately for you, if you've chosen to secure your house with one, Amazon's selling the Arlo Essential for just 67.99, which is 66 percent off of the original price. Not only does this smart device offer 1080p video, but it also offers a night vision mode and two way audio. The Arlo Essential is easy to set up and has a wide field of view (180 degrees), which is good for when you need to cover a larger area like a driveway.

Folks on the lookout for a new video doorbell or home security camera might be interested in checking out the latest sale on Arlo gear. Arlo's wireless video doorbell will let you chat with whoever's at your door via your phone. The doorbell, which you can plug in if you wish, offers a 180-degree wide field view and HD video with HDR. It captures video prior to motion-activated recordings, so you can see what caught the camera's attention (such as what someone was doing right before ringing the doorbell). You can speak to whoever's at your door from your phone thanks to two-way audio support.

Each Arlo Pro camera generation has been better the last, but it was hard to imagine how the Arlo Pro 3 could be improved. The folks at Arlo must have felt the same because they barely made any changes for this fourth-generation device, the Arlo Pro 4. There is one big change, though: You no longer also need the Arlo SmartHub base station, which has been a staple component of every Arlo Pro camera going back to the product's introduction. While you can use the Arlo Pro 4 with a SmartHub if you have one, it's not strictly necessary to get a wireless signal sufficiently strong to deploy this indoor/outdoor camera outside. Aside from the completely wire-free connectivity, the new camera is a spec-for-spec reproduction of the Arlo Pro 3. It has a 160-degree field of view, a 12x digital zoom, and captures video at 2K resolution.

This week our reviews cross several categories: first up, Andrew Tarantola drove the VW ID.4 EV around the Bay Area to see how Volkswagen fared with a compact SUV. Meanwhile, Nicole Lee found a lot to like about Mila's smart air purifier, which has several themed filters and modes that can be customized. Billy Steele listened to Bose's new Sport Open Earbuds, which are designed to sit just outside the ear to allow for better awareness of one's surroundings. And in a quest for better home security, Devindra Hardawar installed Arlo's Video Doorbell and Pro 3 cameras around his home to check out what the system could do. Nicole also considered several smart lights and clocks to see which deserves a spot on your nightstand, and I tested four smart white noise makers designed to be used in a nursery. After driving the VW ID.4 EV, Andrew Tarantola concluded that it's a solid first attempt at a practical electric car from the German automaker.

Soon after moving to a house in the Atlanta metro area last year, I knew I needed a video doorbell. UPS and FedEx would often drop boxes off and never alert me (not great when package thieves are everywhere!). Plus, sales people had the gall to ring my doorbell, unmasked and oblivious to the global pandemic. And if I was playing with my toddler in the backyard or working in the basement, I had trouble hearing if someone was at my door. A video doorbell would solve all of those issues, and give my family a little peace of mind to boot.

Battery-powered security cameras are a great option for outdoor use, because they remove the logistical hassle of finding a convenient electrical outlet to power them. But their easier installation comes with a cost, as they tend to be priced higher than their AC-powered counterparts. The $139 Vacos Cam would seem to be the best of both worlds, then--supremely flexible, modestly priced. Unfortunately, testing revealed this camera to be far from a polished product. While its video quality and smart motion detection are solid, its barely baked app makes the camera virtually unusable. The camera is the latest to crib its look from the Arlo line of home security cameras, in this case the Arlo Go (except that camera connects to the internet via an onboard LTE radio).

The Arlo Pro 4 is a small but mighty outdoor home security camera. The Arlo Pro 4 Spotlight camera has higher video quality and better field of view than almost any camera we've tested--including the popular Nest Cam Outdoor. Other Arlo Pro 4 features include color night vision output, two-way talk capabilities, timely smart alerts, and easy integration with Amazon Alexa and Google Assistant. The Pro 4 is entirely wire-free and runs on a rechargeable battery that can last up to six months per charge. It also has a built-in spotlight that illuminates when motion is detected, and a smart siren that can be triggered automatically or remotely via the Arlo app.
