Download All of Netflix in One Second? Researchers in Japan Just Broke the Internet Speed Record
That's the dream that scientists with Japan's National Institute of Information and Communications Technology have made a reality, achieving a world record in data transmission speed of 1.02 Petabits per second over 1,123 miles -- roughly the distance between Miami and Cleveland.
To put that in perspective, we usually measure internet speed in Megabits per second (Mbps). A Petabit is equal to a billion Megabits, which means the speed achieved by the NICT researchers would measure out to 1,020,000,000Mbps -- more than 3.5 million times faster than the average internet speed in the US right now.
Why would you need to transmit data that quickly? It might seem like a novelty record akin to hooking up 444 gaming consoles to one TV, but the breakthrough speeds have legitimate real-world implications.
'The result represents a major step forward in developing scalable, high-capacity networks and addressing the world's growing demand for data,' the NICT report states.
Locating local internet providers
That's because the researchers used fiber-optic cables that are compatible with infrastructure that already exists. For the test, they used a 19-core optical fiber with a standard cladding diameter of 0.125 mm -- the same thickness currently used in networks around the world.

This 19-core optical fiber is able to use 19 different light paths to transmit data in the same space that's usually taken up by one. That's how you can get such a massive increase in capacity without entirely overhauling the 870,000 miles of undersea cables that run the internet.
We may need that increase in speed sooner than we think, too. A well-known rule in the networking world called Nielsen's law states that a high-end internet user's connection speed grows by roughly 50% each year, doubling every 21 months -- an observation that has held true since 1983. I'd say a high-end internet user has one-gig speeds right now; in a decade, it's not hard to imagine that being 10 Gigabits per second. To keep up with growing demand like that, we'll need a lot more records to be broken.

Roblox (RBLX) Unveils New Licensing Platform With Netflix And Sega Partnerships
Roblox recently launched an innovative licensing platform that includes partners such as Netflix and Lionsgate, aiming to simplify the licensing of intellectual properties for creators. This initiative aligns with a broader tech rally, as evidenced by Nvidia and other semiconductor stocks contributing to a tech-heavy Nasdaq rise. During the last quarter, Roblox saw its stock price soar by nearly 90%, likely buoyed by these developments and the general investor confidence in tech stocks, despite a broader market that was mixed following inflation data and financial sector earnings. Such progress likely reinforced investor optimism regarding Roblox's future growth potential. You should learn about the 2 possible red flags we've spotted with Roblox. The end of cancer? These 25 emerging AI stocks are developing tech that will allow early identification of life changing diseases like cancer and Alzheimer's. The recent launch of Roblox's licensing platform has the potential to significantly enhance user engagement through partnerships with major players like Netflix and Lionsgate, while also potentially boosting future revenue. This development aligns with key strategic initiatives such as AI-driven enhancements and international market expansions, reinforcing the narrative of potential growth through diversified revenue streams. Over the past three years, Roblox has achieved a substantial total return of 181.33%, indicating strong long-term shareholder value despite current unprofitability. Additionally, over the past year, Roblox's performance exceeded both the US market and the Entertainment industry, which saw returns of 11.4% and 67.6%, respectively. With a current share price of US$111.83, which is above the analyst price target of US$87.04, it highlights optimism among investors about the company's growth prospects. However, the need for Roblox to address unprofitability and execution risks remains critical to meeting earnings forecasts. The anticipated developments from AI and licensing initiatives could drive substantial future growth, yet analysts project a revenue increase of 17.9% annually, slower than assumed robust industry expansion. Investors should weigh the current price premium against potential upside from growing market presence and improved operational efficiencies.

The Future Of Porsche's Racing Tech Transfer to Street Cars? Software.
On April 12, 2025, Porsche made history, becoming the first automaker to win three classes of professional motorsports with three different powertrains on the same day. In California, a 963 hybrid won the LMDh class and took the overall win at the IMSA Long Beach Grand Prix while a 911 GT3 R won the GTD Pro class in the same race with pure combustion engine. Across the country, the 99X Electric won the Miami e-prix in Formula E on pure battery power. Different as they may be, each shares a common link with the Porsche road cars you can buy today and in the future. Porsche uses motorsport to drive tech innovation, focusing on software as the key to improving road cars. Software impacts drivability and efficiency, with lessons from racing series shared across projects. This approach is cost-effective and enhances both performance and development. This summary was generated by AI using content from this MotorTrend article Read Next Racing Technology for the Street 'We have a philosophy that, yes, motorsport is part of our DNA,' Porsche vice president of motorsport, Thomas Laudenbach, told MotorTrend , 'and I cannot imagine Porsche without motorsport, but we are not doing motorsport for the sake of its own. We do motorsport to give a contribution to the company, and this is exactly what we are talking about.' In the past, tech transfer from racing to the road consisted mostly of more power and better aerodynamics, but as everything on a car has become linked and controlled by computers, the next frontier is in the software that controls them. Hard parts like engines, suspension, and aerodynamics are fairly mature technologies, but automotive software is still in its relative infancy. 'It is still a very steep curve,' Laudenbach said. 'It's growing so fast, it's changing so fast…I mean, if you look at the combustion engine, obviously development [today] is slower like this because you know, it is more and more difficult to make the [next] step. If you look at the software, not only software itself, how we approach it, the tools…I would say [it is] still very steep, the curve, how fast it changes.' It's All in the Software In all three racing series, physical parts on the cars are heavily regulated, particularly when it comes to batteries and electric motors. Software, though, isn't and has become the most important factor in improving lap times and efficiency. 'Everything you can do on the software has a much bigger impact and a much bigger effect in the drivability,' Porsche Formula E driver and reigning champion, Pascal Wehrlein, told MotorTrend , 'because yeah, there's also software things in in a combustion engine, but the effect is just smaller than an electric car. We pay a lot of attention to the software and I would say that is our biggest toolbox for setting up the car and getting quicker and so on. And there's just so many more things you can do on the software compared to a combustion engine. 'How much we are going into the details,' he continued, 'into the smallest details, I would say on the software side is even more than what I did when I was in Formula One, just because there are so many different options on, you know, the four-wheel drive, how to set up the four-wheel drive. How much work do you want to have at the front? At which point in time in the corner you want to have more front torque or less? What you can do on the braking side, on the [energy] recuperation, setting it up for different corners? In certain corners, where it's high speed, you need something different than in the low-speed corner, but then also when the track is bumpy, or not bumpy. We are going so much into the details.' Lauderbach agrees. 'It's absolutely right. We always love about talking about hardware. And I did develop combustion engines for 18 years, so I'm a real mechanical guy, and it's absolutely right, probably the bigger part is software. And but this is the good thing about it because some things [physical] we are not allowed to touch [under the regulations]. But we have a big freedom of software, and I think that's good because racing should give freedom where it is beneficial also for your brand. And that's certainly in software and I think this is probably also the biggest change between the projects.' Because the applications are so different, it's not as simple as just sharing code between teams in different series or with the engineers working on the road cars. Instead, it's the exchange of knowledge and ideas which brings this tech to cars like the 911 GTS T-hybrid. 'It's for sure not a carryover part,' Laudenbach said, 'but it's from learning about the difficulties, about the weak points, about the solutions, for sure they benefit from each other. 'When you have more than one project,' he said, 'you just work it on in a wider range and then you always find synergy. These two programs (Formula E and LMDh) benefit from each other in various areas. And at the same time, this is linked so close to our road car development. We work a lot on road cars as well in the motorsport department and do benefit from each other. If you tell your engineers, oh, please sit together with these guys from this program, then you know what they do? They sit together for an hour, they chat, and they go to it. If you sit side by side, if you meet each other with a coffee, this is the best way to benefit from each other. These two programs benefit, but also this is very beneficial to what we do on road cars, even inside the motorsport department.' It's not just about making the cars faster, either. Power makes heat, and heat needs to be dealt with before it breaks things, on a race car or a road car. Efficiency matters in racing because using less fuel or electricity allows you to go farther between pit stops, and it matters for the same reason on the street. 'Look at Formula E,' Laudenbach said. 'It's not our battery, but we control the thermal system [and] energy management. That's a lot of control systems. That's a lot of software. I mean, if we work with AI in the meantime and there you can learn a lot of the one side and transfer it to the other. Sometimes then you figure out that, okay, I can only take this because this [other technology] is not allowed. It's never carry over one to one. 'But you still learn a lot about how to handle it. It's software functions, it's control systems, it's sometimes also just the tools that we use, the approach that you take is not always [about] the final product. In the end, you have the product, there, no matter if it's software, hardware, but it's also, how do you approach it, because you're always looking for being most efficient. Especially Formula E, [where] we have a cost cap. It's a factor to say, okay, can I reach a certain goal with the smallest amount of money? These kind of things we always exchange because it's in the background.' Cheaper and Easier Not only are software learnings easier to transfer between programs, software is also easier to iterate on and less expensive to develop. 'Compared to hardware,' he said, 'it's not that cost intensive. Yes, you have you have the labor. But you know, you' not always having to change your bits and pieces. And don't forget, if you talk about bits and pieces, you always have to stop and throw parts away. So it's a lot more, let's say, cost efficient.' Whether in the office or trackside, the way data is managed and analyzed has changed a lot in the past decade. 'If we would do it like 10 years ago,' Lauderbach said, 'where the engineer himself goes through all the raw data, that doesn't work anymore. You got to feed your data through automatic analysis. It's just more [a question of], how do you analyze? How do you get something out in order to make the car quicker? This is a lot more or this is high sophisticated, a lot more automation and algorithms, than 10 years ago. 'It's a software basically to calculate what the car's doing because you got sensors. Obviously, you want to calculate some figures, you see what the car's doing in order to feature simulations. The simulation then gives you back again in which direction you have to go.'

Sony's pocket-sized RX1R camera returns with its first update in 10 years
After nearly a decade, Sony has announced a new version of its fixed-lens compact RX1R camera that was last updated in 2015. The new third generation RX1R III arrives with the same 35mm full-frame Exmor R sensor as its predecessor, but with a bump from 42.4 to 61 megapixels. It also benefits from Sony's latest Bionz XR and AI image processors to deliver better autofocus that can track the movement of human bodies and more accurately focus on their heads and eyes. The RX1R III will be available sometime in July for approximately $5,099.99, according to Sony. That's considerably more expensive than the RX1R II, which launched in 2015 for $3,300. The RX1R III's compact size and Zeiss Sonnar T 35mm F2 lens puts the camera in competition with the $4,899.95 medium format Fujifilm GFX100RF and the $5,995 full-frame Leica Q3 – both of which also feature fixed lenses. To compensate for that lens limitation, the RX1R III includes a Step Crop Shooting function that allows photographers to switch between 35mm, 50mm, and 70mm focal lengths achieved through sensor cropping. The camera also features a macro mode activated by a ring on the lens that can be used to focus on subjects as close as 20cm. The camera has a body made of magnesium alloy. To help make the RX1R III as light and portable as possible, Sony is now using a fixed screen on the back that can no longer be tilted up and down. The change means you may find yourself having to contort your body when trying to capture low-angle shots using the camera's screen or 2.36 million dot OLED electronic view finder. Sony is once again positioning this camera as a high quality shooter that's far less cumbersome to carry than larger mirrorless options or DSLRs, and its performance reflects that. Shooting speeds max out at just five frames per second, and the RX1R III can capture 4K video at 30 fps or 1080p at up to 120 fps (the RX1R II maxed out at 1080p) with the option to use Sony's S-Cinetone picture profile for a more cinematic look. The RX1R III also includes 12 different quick access Creative Looks that can be customized and applied to both stills and video. And like the Sony A7R V, its autofocus system features 693 phase-detection points and is capable of tracking human motion to determine where a subject's eyes are supposed to be, even if they're not looking directly at the camera or their face is obscured. It seems like a worthwhile upgrade over the last generation, but if you don't mind a bit more bulk, there are more capable and affordable alternatives from Sony.
