Desarrollo Digital: Weekend sale at Amazon: 17 deals I’d buy on TVs, laptops, headphones, and more

At any one time of the year, there are always fantastic deals available at Amazon. This weekend is no different with plenty of tech products sitting at prices just as good as over Black Friday last year. I’ve spotted laptops, TVs, headphones, and even small appliances with great deals at Amazon right now, all of which you can check out below. Some highlights include old favorites like the Apple MacBook Air M1 for its record-low price of $749.99 (was $999), the Google Pixel 8 for $549.99 (was $699), and brand-new products like the Bose QuietComfort Ultra wireless earbuds for $249 (was $299). I’ve also found some superb options for big-screen TVs on a budget like this 65-inch TCL Q6 QLED TV for $498 (was $699).  Note that most of these recommendations were previously on sale with Amazon’s Presidents’ Day sale on Monday so there’s likely not long left to pick them up in some cases. We’ve already seen most of the deals on certain categories – namely discounts on Amazon’s own-brand devices – already discontinued these past few days.

Desarrollo Digital: You’ve probably missed Silo on Apple TV Plus – but it’s must-watch sci-fi

February can be a miserable month in my native UK. It’s awash with rain one day and icy cold the other. And while the days gradually get longer here, there never seems to be enough sunlight to drive away the winter blues. So it’s been a good time for me to stay inside and get familiar with a streaming service. Even if you live in warmer climates, there are still days when going outside might seem like a chore, and the only thing on your agenda is curling up with a good series.  May I recommend Apple TV Plus’ Silo. This sci-fi show flew a good bit under my radar, and I think it’s likely to be the same for others, with glossier shows like Ted Lasso, The Morning Show, Severance, and For All Mankind stealing the attention of would-be binge-watchers.  But over time, Apple TV has become the low-key home for great sci-fi series, with Silo being one of the best.  Way down we go (Image credit: Apple TV Plus) Based on a trilogy of books of the same name written by Hugh Howey, Silo has been adapted for TV by Graham Yost and revolves around a society living in a vast underground silo in a dystopian future where some apocalyptic disaster or war has rendered life outside seemingly impossible.  This premise alone makes Silo a great TV to watch while you’re indoors on a dark and wet evening, the claustrophobic nature of the show’s setting almost mirroring your own – I live in a small London flat so I can empathize with a lack of living space.  The rules that govern the 10,000-strong society are equally claustrophobic, with knowledge of the world before and historical events purged from the almost literal pages of history. What could present an irritatingly vague setting, instead creates a foundation on which deft world-building can be layered. This happens almost literally, with the upper levels of the silo playing host to dignitaries, security, and the governors of the silo, while the mid- to lower levels contain blue-collar workers.  It may seem like a ham-fisted analogy to class division, but this actually paves the way for nuance with physical upward mobility letting people move beyond their roles, stations, and perceived class. And it’s here Juliette Nichols, played by Rebecca Ferguson, steps into the spotlight.  Digging deep (Image credit: Apple TV Plus) Initially an engineer who gets interviewed by the silo’s sheriff about the death of her friend, Nichols is soon elevated into the position of sheriff herself. And it’s through her eyes that we see the nuance of society in the silo, while also being fed all manner of mysteries; from wondering who holds real power in the silo, to what came before and what’s really going on outside. Silo’s main premise may feel somewhat familiar to anyone who’s played a game in the Fallout series, but where it stands out for me is in the details. While Netflix’s Snowpiercer creates in a schlocky and overly obvious manner distinct societies based around positions on a perpetually moving train traversing a frozen Planet Earth, Silo’s world is subtle.  The folks in the position of power aren’t decadent individuals, but people who have the weight of the world pressing down on them, while folks in the mid-levels have just as interesting roles though with less authoritarian clout. Sure, those in engineering are tough and tattooed, leaning into post-apocalyptic stereotypes, but in the context of maintaining a massive generator needed to keep the silo alive, their brusqueness makes sense.  It’s the details in this context that kept my eyes fixed on Silo; the broad catwalk heading to the imposing doors of the Judiciary (a group of law enforcers), the retro-futuristic design of the IT department, the Sheriff’s office that looks like it was taken from a small midwestern town and bunged underground. There’s a richness to Silo‘s sets and setting, despite the limitations of being in what’s basically a concrete bunker.  It reminds me of Fargo, where the camera doesn’t mind lingering on shots just that little bit longer than normal, letting you drink in the details and tone of a scene.  The color grading also expertly adds to the atmosphere and detail of the silo. Mostly muted to convey life underground without sunlight, there are occasional bursts of color in people’s homes or on the shop lights of bustling market areas. All this emphasizes the world-building that Silo is steeped in, making it hard to look away even though there’s a lack of real threats like the overarching menace of The Last of Us’ infected to keep the tension ramped up at all times.  The cast is strong too, with Fergerson portraying a tough engineer and equally tough sheriff but one with heart, an inquisitive nature, and dogged determination. It could have been easy for Nichols to just be a hard-as-nails character with a softer side deep down, but instead, Ferguson brings a lot of modulation to the character. She can go from a cool detective to a warm partner to an estranged daughter to an unrelenting force, all giving the sense that Nichols isn’t as predictable as one might first think while still being someone we can empathize with.  David Oyelowo, who plays Sheriff Holston also steals a few scenes. While Tim Robbins’ Bernard Holland deftly conveys a low-key sense of threat below the veneer of a seemingly anal and side-lined IT department head. Even Common, who plays outright threatening Judicial security head, Robert Sims, has more subtlety to him than just a big man in an ‘I’m the bad guy’ leather jacket.  Silo could have gone the soapy silliness route of Snowpiercer (again the TV show, not the excellent movie) or delved into the perpetual grimness of The Road. Instead, it presents thousands of humans getting by in a ruined world, with the trials and tribulations that affect them being almost parallel to ours; we have our conspiracy theories and so do the

Desarrollo Digital: ‘Inspired by a car wash’: Researchers unveil quasi-universal tag that’s virtually unhackable thanks to glue — terahertz antitampering tag could help save billions of dollars in counterfeiting costs

Traditional radio-frequency identification (RFID) tags, commonly used for product authentication, have several limitations including size, cost, energy requirements, and security vulnerabilities. Researchers at MIT have developed a revolutionary cryptographic ID tag that overcomes these hurdles and could help combat the billion-dollar problem of supply chain counterfeiting. This minuscule, battery-free tag, dubbed the ‘tag of everything,’ can authenticate almost any product, making it a powerful tool against imitation parts and fraudulent goods. Inspired by a car wash The tag’s innovative design was partly inspired by a car wash. Researchers noted how the car wash used a fragile RFID tag to authenticate membership, which would be destroyed if tampered with. They took this concept further, focusing on authenticating the item itself rather than the tag. The team achieved this by mixing microscopic metal particles into the glue that attaches the tag to the product. These particles create a unique pattern on the item’s surface, akin to a fingerprint, which can be detected using terahertz waves. If a counterfeiter attempts to remove and reattach the tag, the pattern is destroyed, making the tag virtually unhackable. This ground-breaking technology also incorporates a machine-learning model that can identify similar glue pattern fingerprints with over 99% accuracy, further enhancing its anticounterfeiting capabilities. It’s tiny enough to fit on almost any product, from industrial components to medical devices, and operates on low power levels supplied by photovoltaic diodes. Crucially, it offers robust security measures, including a popular cryptography scheme that guarantees secure communications. There are limitations, however. The tag’s sensor must be within 4cm to get an accurate reading, and the angle between the sensor and tag must be less than 10 degrees. However, the researchers are optimistic about overcoming these challenges in future work. Via TechXplore More from TechRadar Pro Leer más sobre desarrollo digital

The Prodigy universal processor
Webs

Desarrollo Digital: ‘Run AI models for as low as $5,000’: plucky CPU startup that claimed 99% saving on AI costs now wants to sell you an AI workstation — with an unbelievable price tag and 1TB RAM

CPU startup Tachyum has previously said that one of its Prodigy Universal Processor units can rival dozens of Nvidia H200 GPUs. The 192-core 5nm processor delivers 4.5 times the performance of the best processors for cloud workloads, and claims to be six times more effective than GPUs for AI. Now the firm has announced the Prodigy ATX Platform, an AI workstation that promises to run advanced AI models for just $5,000. The ambitious system, which features an impressive 1TB of memory, is designed to make sophisticated AI models accessible to a wider audience. The Prodigy ATX Platform is built around a 96-core Prodigy processor, which is designed with only half of its die enabled, a strategy aimed at reducing power consumption and enhancing yield, thereby lowering costs and making the platform more accessible. Effective for LLMs The system is expected to come equipped with 1TB of DDR5-6400 SDRAM using 16 memory modules, offering a peak bandwidth of 819.2 GB/s. The system’s design includes three PCIe x16 5.0 slots, three M.2-2280 NVMe slots with a PCIe 5.0 x4 interface, and SATA connectors for SSDs and HDDs. Tachyum says its Prodigy ATX Platform is particularly effective for running LLMs which are notorious for their high memory capacity requirements.  A single Prodigy system can reportedly run a ChatGPT4 model with 1.7 trillion parameters, which would require 52 NVIDIA H100 GPUs to run at a significantly higher cost and power consumption.  Despite the impressive specifications, there are doubts about the economic viability of the Prodigy ATX Platform for Tachyum. As Tom’s Hardware points out, the total cost of the system components, excluding the Prodigy processor, is estimated to be around $4800. However, Tachyum’s CEO, Dr. Radoslav Danilak, remains optimistic, stating that the platform’s powerful AI capabilities will enable organizations of all sizes to compete in AI initiatives. “Generative AI will be widely used far faster than anyone originally anticipated,” Dr. Danilak said. “In a year or two, AI will be a required component on websites, chatbots and other critical productivity components to ensure a good user experience. Prodigy’s powerful AI capabilities enable LLMs to run much easier and more cost-effectively than existing CPU + GPGPU-based systems, empowering organizations of all sizes to compete in AI initiatives that otherwise would be dominated by the largest players in their industry.”  The Prodigy ATX Platform’s launch has been delayed multiple times, with the latest plan pegging the processor’s launch for the second half of 2024. It remains to be seen whether Tachyum can deliver on its promises and revolutionize the AI landscape. More from TechRadar Pro Leer más sobre desarrollo digital

Desarrollo Digital: iOS 18 tipped to get a visual redesign this year – with macOS following later

The design elements in iOS don’t often change – and when they do, it’s not usually by much – but the upcoming iOS 18 software could indeed have a significantly updated look, according to one well-placed source. According to Bloomberg’s Mark Gurman (via 9to5Mac), Apple “is indeed working to update the design of iOS as early as this year”. That doesn’t give us much detail to work with, but it does suggest there will be noticeably different visuals. Gurman – usually reliable when it comes to predicting Apple’s moves – was in part responding to rumors that iOS 18 would borrow some design inspiration from visionOS on the Apple Vision Pro. That “total overhaul” isn’t happening, says Gurman, though it sounds as though Apple may get part of the way there in 2024. New versions of iOS are usually unveiled at Apple’s Worldwide Developers Conference (WWDC) in June, so we don’t have too long to wait to see what Apple’s been working on – and how much different in style it is to iOS 17. An “ambitious and compelling” update iOS 18 will be coming to the iPhone 15 (Image credit: Future | Alex Walker-Todd) The biggest visual overhaul we’ve ever seen for iOS came with iOS 7, launched back in 2013: skeuomorphism (where digital elements are designed like their real world equivalents) was out, and a much more modern look was in. In the decade since, app icons and menus have been tweaked and adjusted, but there hasn’t been what you would describe as a full-scale redesign. We’ll have to wait and see what iOS 18 brings when WWDC 2024 gets underway. Gurman has previously gone on record as saying that iOS 18 is going to be an “ambitious and compelling” upgrade, so it sounds as though there’s a lot to look forward to. As with everything else in tech lately, generative AI is likely to play an important role – with Siri and iOS set to be updated with some big new AI-driven capabilities. According to Gurman, a visual refresh is also coming to macOS, though it’ll lag behind iOS: the updates Apple is planning to the macOS design are apparently still in the early stages, and won’t be completed until 2025 or 2026.

Desarrollo Digital: Shattering the ‘copper or optics’ paradigm: humble plastic could become key material in race to conquer AI data center market – it is cheaper, lighter, thinner and more power efficient

With the expansion of data centers and the rise of generative AI, LLMs, IoT and video streaming services, the demand for advanced interconnects is higher than ever. Conventional interconnects using copper have critical bandwidth limitations caused by the ‘skin effect’, where the current flowing through the cable is concentrated at the surface of the conductor. Optical interconnects, while offering high capacity over longer distances, require significant capital expenses for short-reach, high-volume links deployment. Point2’s E-Tube provides a low-cost, low-loss broadband dielectric waveguide solution that could serve as an advanced alternative to existing electrical and optical interconnects in high-speed, short-reach communication links. It’s 80% lighter and 50% less bulky than copper cables, and could reduce power consumption and the cost of optical cables by 50%, with picosecond latencies that are three orders of magnitude better. New partners The metal film laminated rectangular dielectric waveguide has been shown to achieve an impressive level of throughput‑distance product, bending radius, and channel density without requiring a complex manufacturing process. It can be deployed for 800G/1.6T/3.2T cable speeds and beyond. You may not have heard of it before, but that’s about to change as Point2 recently announced plans to partner with Bosch Venture (the venture capital arm of the Bosch Group) and Molex to commercialize its E-Tube technology, replacing electrical and optical interconnects in high throughput links, including (but not limited to) 100/400 Gbps board-to-board communications. “Escalating network capacity demand in future AI/ML data center and automotive use cases requires a new approach to cable interconnect,” said Jairo Guerrero, VP and GM of the Copper Solutions business at Molex. “Point2 has developed an E-Tube platform that can scale to the connectivity requirements of data centers and future automotive network architectures. Partnering with Point2 to commercialize E-Tube is a natural fit for Molex’s connectivity business and helps position our company to better respond to growing customer demands.” More from TechRadar Pro Leer más sobre desarrollo digital

Where Wordle challenges you to guess a new five-letter word each day, Quordle presents you with four puzzles to solve. And rather than complete them in turn, you do so simultaneously. You get nine guesses, rather than the six for Wordle, but the rules are otherwise very similar. It’s played online via the Quordle website and you can also get to it via the Merriam-Webster site, after the dictionary purchased Quordle last year. As with Wordle, the answers are the same for every player each day, meaning that you’re competing against the rest of the world. And also as with Wordle, the puzzle resets at midnight so you have a fresh challenge each day. The website also includes a practice mode – which I definitely recommend using before attempting the game proper! – and there are daily stats including a streak count. You also get Quordle Achievements – specific badges for winning a game in a certain number of turns, playing lots of times, or guessing particularly hard words. Oh, and it’s difficult. Really difficult. What are the Quordle rules? The

Nothing Phone 2 showing screen and lit glyph LED lights

Desarrollo Digital: Nothing Phone 2a renders appear to reveal the promising mid-ranger in full

Leaks for the Nothing Phone (2a) are ramping up as we inch closer to its March 5 launch date. This time, a series of what may be official images have recently surfaced showing off the mid-ranger’s final design in full. These renders, strangely enough, were posted on the Nothing Community forums by user Greg2024. The original page has since been deleted, but fortunately, people managed to save its contents. Looking at the leak, the Nothing Phone (2a) looks radically different from the older Phone (2) model. The rear camera lenses will be horizontally aligned and placed at the center of the device’s upper half. What’s more, the glyph is completely gone. In its place are three light strips situated around the cameras. Below that, you’ll notice a pipe-like pattern moving downward. [Exclusive] #NothingPhone2aNothing Phone 2a is coming up with Plastic frame!! pic.twitter.com/HkTjVvF3NOFebruary 22, 2024 See more On the front, you have the rumored 6.7-inch AMOLED screen surrounded by thin bezels. The pinhole selfie lens is at the top, plus the images show the power button on the right with volume control on the left. Finally, the Nothing Phone (2a) will be available in black or white. Seeing into the future That’s everything in the leak, so now the question is what we can learn from the renders because, in our opinion, it seems legit. For starters, the rear glyph morphing into the simplified light array is probably a cost-cutting measure by developers. The same goes for the wireless charging coil. That’s gone having been replaced by the lines snaking down. What adds further credence to the leak are the cameras. Around mid-February, industry insider Abhishek Yadav got his hands on what he claimed was an early version of the smartphone, and wouldn’t you know, it sports horizontally aligned lenses. It’s also worth looking at the tagline for the Nothing Phone (2a) launch event which is “Fresh. Eyes.” And what looks like a pair of eyes? Two cameras sitting next to each other. Missing info Device specifications were not part of the leak; however, the company did confirm in a recent YouTube video that the smartphone will run on a custom-built MediaTek Dimensity 7200 Pro chipset. The rest of the model’s hardware capabilities are officially unknown at this time although rumors are claiming it’ll have at least 8GB of RAM and 128GB of storage. The price point is a mystery too; however, 9To5Google postulates it could be roughly $380/£300/€349. As always, take this information with a grain of salt. Things could always change in the next couple of weeks. Maybe the company will stick with the old vertically aligned lens array. Around the same time as this leak came out, the CMF by Nothing sub-brand announced two new audio products; most notably the Neckband Pro, a pair of earbuds equipped with presumably a battery pack that’ll hang around your neck. These are slated to have “best in class ANC” or active noise canceling. If you want our opinion on what are the best ANC devices, check out TechRadar’s list of the best noise-canceling earbuds for 2024. You might also like Leer más
