In honor of FreeDOS's 25th birthday, project founder and coordinator Jim Hall agreed to answer the 10 best questions submitted by Slashdot readers. You asked and he answered! Read on for Jim's interview.

Raspberry Pi today introduced a new version of its popular line of single-board computer. The Raspberry Pi 4 Model B is the fastest Raspberry Pi ever, with the company promising "desktop performance comparable to entry-level x86 PC systems." The specifications are: A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU (~3x performance); 1GB, 2GB, or 4GB of LPDDR4 SDRAM; full-throughput Gigabit; Ethernet; dual-band 802.11ac wireless networking; Bluetooth 5.0; two USB 3.0 and two USB 2.0 ports; dual monitor support, at resolutions up to 4K; VideoCore VI graphics, supporting OpenGL ES 3.x; 4Kp60 hardware decode of HEVC video; and complete compatibility with earlier Raspberry Pi products. It starts at $35.

An anonymous reader quotes a report from VentureBeat: At the International Supercomputing Conference (ISC) in Frankfurt, Germany this week, Santa Clara-based chipmaker Nvidia announced that it will support processors architected by British semiconductor design company Arm. Nvidia anticipates that the partnership will pave the way for supercomputers capable of "exascale" performance -- in other words, of completing at least a quintillion floating point computations ("flops") per second, where a flop equals two 15-digit numbers multiplied together. Nvidia says that by 2020 it will contribute its full stack of AI and high-performance computing (HPC) software to the Arm ecosystem, which by Nvidia's estimation now accelerates over 600 HPC applications and machine learning frameworks. Among other resources and services, it will make available CUDA-X libraries, graphics-accelerated frameworks, software development kits, PGI compilers with OpenACC support, and profilers. Nvidia founder and CEO Jensen Huang pointed out in a statement that, thanks to this commitment, Nvidia will soon accelerate all major processor architectures: x86, IBM's Power, and Arm. "As traditional compute scaling has ended, the world's supercomputers have become power constrained," said Huang. "Our support for Arm, which designs the world's most energy-efficient CPU architecture, is a giant step forward that builds on initiatives Nvidia is driving to provide the HPC industry a more power-efficient future."

Long-time Slashdot reader jrepin writes: The KDE community has released Plasma 5.16, the newest iteration of the popular desktop environment. It features an improved notification system, Not only can you mute notifications altogether with the Do Not Disturb mode, but the system also groups notifications by app.

Developers also focused on user's privacy. When any application accesses the microphone, an icon will pop up in your system tray, showing that something is listening. Vaults, a built-in utility to encrypt folders, are easier and more convenient to use.

Dolphin file and folder manager now opens folders you click on in new tabs instead of new windows. Discover software manager is cleaner and clearer as it now has two distinct areas for downloading and installing software. The Wallpaper Slideshow settings window displays the images in the folders you selected, and lets you select only the graphics you want to display in the slideshow.

For a more comprehensive overview of what to expect in Plasma 5.16, check out the official announcement or the changelog for the complete list of changes.

The System76 Gazelle laptop is finally available. From a report: What makes this laptop so special (besides its pre-installed Linux-based operating System), is its impressive specifications. You see, System76 has supercharged it with a 9th generation Intel Core i7 Processor (9750H) and NVIDIA GTX 16-Series Graphics. It even has something the pricey MacBook Pro doesn't -- the ability to be configure with up to 64GB. Yeah, Apple's laptop can only have a maximum of 32GB. The Gazelle can be configured with additional top specs, such as an NVMe SSD up to 2TB. Actually, it can accommodate two such drives, so you can theoretically have 4TB of speedy storage. You can opt for either a 15 or 17-inch display, both of which have a 1080p resolution. Regardless of screen size, you get a full keyboard too, meaning it has a number pad on the right. It ships with Ubuntu or Pop!_OS pre-installed and starts at $1099.

At the Electronic Entertainment Expo (E3) on Wednesday, Netflix shared details of its plans to develop its original shows into video games. Hollywood Reporter reports: Among the program of upcoming games, Stranger Things 3: The Game was highlighted, described by Netflix as "an adventure game that blends a distinctively retro art style with modern gameplay mechanics to deliver nostalgic fun with a fresh new twist." Playing as a character from the show, the user will be tasked with solving puzzles and battling the Mind Flayer. Dave Pottinger, CEO and co-founder of BonusXP, shared that the game will feature old-school graphics.

Two characters from the game were revealed at the panel: Max, who will exhibit karate kicks and the ability to add fire damage to those kicks; and Eleven, described by Chris Lee, director of Interactive Games at Netflix, as "the most powerful character in the game" -- she will have psychic push power. The game will launch on July 4 and be available on Nintendo Switch, Playstation 4, Xbox One and other consoles. In addition, a special announcement was made at the panel about a Stranger Things mobile hybrid RPG/puzzle game that will launch in 2020. The game is a collaboration with Next Games, which is based out of Helsinki, Finland. Stranger Things isn't the only show that's planning to have its own game. "Netflix show The Dark Crystal: Age of Resistance Tactics is also set to become a 'turn-based tactics' game challenging fans to recruit an army and act as their commander in a series of campaign battles," the report adds. "No specific date was mentioned, but the game will launch this year on various consoles."

MojoKid writes: AMD let loose today with a number of high profile launches at the E3 2019 Expo in Los Angeles, CA. The company disclosed its full Zen 2 Ryzen 3000 series microarchitecture, which AMD claims offers an IPC uplift of 15% generation over generation, thanks to better branch prediction, higher integer throughput, and reduced effective latency to memory. Zen 2 also significantly beefs up floating point throughput with double the FP performance of the previous generation. AMD also announced a 16-core/32-thread variant, dubbed Ryzen 3950X, that drops at $750 -- a full $950 cheaper than a similar spec 16-core Intel Core i9-9960X. On the graphics side, AMD's RDNA architecture in Navi will power the company's new Radeon RX 5700 series, which is said to offer competitive performance to NVIDIA's GeForce RTX 2070 and 2060 series. The Navi-based GPU at the heart of the upcoming Radeon RX 5700 series is manufactured on TSMC's 7nm process node and features GDDR6 memory, along with PCI Express 4.0 interface support. Versus AMD's previous generation GCN (Graphics Core Next) architecture, RDNA delivers more than 50% better performance-per-watt and 25% better overall performance. Greater than 50% of that improvement comes from architecture optimizations according to AMD; the GPU also gets a boost from its 7nm process and frequency gains. Radeon RX 5700 and 5700 XT cards will be available in market on July 7th, along with AMD Ryzen 3000 chips, but pricing hasn't been established yet for the Radeon GPUs.

PC gaming platform BlueStacks has launched BlueStacks Inside that enables mobile game developers to publish their games on Steam with no porting to the PC required. From a report: BlueStacks inside has a one-step software development kit (SDK) that lets developers take existing mobile games to Steam and Discord. The initial launch will include several high-profile developers like KOG, Funplus, Fabled Game Studio, and many others whose games will be available directly on Steam. Mobile developers have started allocating large budgets to game development, and that means mobile games can be competitive on Steam without a ton of modification.

With games like Lineage 2: Revolution and PlayerUnknown's Battlegrounds, graphics and gameplay push the limits of what a mobile device can do. On the other hand, gamers are caught in a struggle to maintain devices that can keep up with demanding games. BlueStacks Inside gives developers an opportunity to reach a much wider and valuable PC-based audience without the need to hire a separate PC development team. Players can use their PCs to do the heavy lifting for games their phones would otherwise not be able to run well.

The long-awaited Mac Pro is here. From a report: The new Intel Xeon processor inside the Mac Pro will have up to 28 cores, with up to 300W of power and heavy-duty cooling, "so it can run unconstrained at full power at all times." System memory can be maxed out at an eyebrow-raising 1.5TB, says Apple. There are eight internal PCI Express slots, with four of them being double-wide. Two USB-C and two USB-A ports will grace the front of the system, which is at least one more USB-C port than you'll find on a majority of desktop PC systems and cases today. With this Mac Pro, Apple is launching a custom expansion module it calls an MPX Module. This is a giant quad-wide PCIe card that fits two graphics cards, has its own dedicated heatsink, and also has a Thunderbolt 3 connector on the bottom for extra bandwidth / power / display connectivity. Apple says you can spec that out with AMD's Radeon Pro Vega 2 or Radeon Pro Vega 2 Duo, the latter of which would get you four GPUs in total. The power supply of the new Mac Pro maxes out at 1.4kW. Three large fans sit at the front, just behind the new aluminum grille, blowing air across the system at a rate of 300 cubic feet per minute. It starts at $5,999.

Samsung and AMD announced today a new multi-year strategic partnership between the two companies, where Samsung SLSI will license graphics IP from AMD for use in mobile GPUs. From a report: The announcement is a major disruptive move for the mobile graphics landscape as it signifies that Samsung is going forward with the productization of their own in-house GPU architecture in future Exynos chipsets. Samsung is said to have started work on their own "S-GPU" at its research division back around in 2012, with the company handing over the new IP to a new division called "ACL," or Advanced Computing Lab in San Jose, which has a joint charter with SARC (Samsung Austin R&D Center, where Samsung currently designs its custom mobile CPU & memory controller IP). With today's announced partnership, Samsung will license "custom graphics IP" from AMD. What this IP means is a bit unclear from the press release, but we have some strong pointers on what it might be.

Samsung's own GPU architecture is already quite far along, having seen 7 years of development, and already being integrated in test silicon chipsets. Unless the deal was signed years ago and only publicly announced today, it would signify that the IP being talked about now is a patent-deal, rather than new architectural IP from AMD that Samsung would integrate in their own designs. Samsung's new GPU IP is the first from-scratch design in over a decade, in an industry with very old incumbents with massive patent-pools. Thus what today's announcement likely means is likely that Samsung is buying a patent-chest from AMD in order to protect themselves from possible litigation from other industry players.

Synthetic events remain a big security hole for macOS in spite of Apple's recent efforts to prevent malicious applications from abusing this feature. From a report: Speaking at the second edition of the Objective by the Sea security conference that was held in Monaco over the weekend, Patrick Wardle, a well-known Apple security expert, has revealed a zero-day impacting Apple's macOS operating system, including the new version launched today. The zero-day is a bypass of the security protections that Apple has put in place to prevent unauthorized access to synthetic events. Synthetic events are a macOS mechanism that allows applications to automate mouse clicks and keyboard input. It was created for the sake of automation and can be used via either the Core Graphics framework or the AppleScript scripting language. [...]

For almost two years now, Wardle has been looking at Apple's countermeasures aimed to prevent the abuse of synthetic events. He previously showed two methods[1, 2] of bypassing Apple's synthetic events protections, so much so that Apple decided last year to block access to synthetic events by default. But over the weekend, Wardle disclosed a new way of bypassing these latest protections, once again. "It's the gift that keeps giving," Wardle told ZDNet via email. "And actually gets more and more valuable as Apple adds more protections (privacy and security mechanisms) that can be 'allowed' by a single synthetic click." The new technique is possible because of the Transparency Consent and Control (TCC) system. Wardle says the TCC contains a compatibility database in the form of a file named AllowApplications.plist. This file lists apps and app versions that are allowed to access various privacy and security features, including synthetic events.

The NLNet Foundation is a non-profit supporting privacy, security, and the "open internet". Now the group has approved funding for the hybrid Libre RISC-V CPU/VPU/GPU, which will "pay for full-time engineering work to be carried out over the next year, and to pay for bounty-style tasks."

Long-time Slashdot reader lkcl explains why that's significant: High security software is irrelevant if the hardware is fundamentally compromised, for example with the Intel spying backdoor co-processor known as the Management Engine. The Libre RISCV SoC was begun as a way for users to regain trust and ownership of the hardware that they legitimately purchase.

This processor will be the first of its kind, as the first commercial SoC designed to give users the hardware and software source code of the 3D GPU, Video Decoder, main processor, boot process and the OS.

Shockingly, in the year 2019, whilst there are dozens of SoCs with full source code that are missing either a VPU or a GPU (such as the TI OMAP Series and Xilinx ZYNQ7000s), there does not exist a single commercial embedded SoC which has full source code for the bootloader, CPU, VPU and GPU. The iMX6 for example has etnaviv support for its GPU however the VPU is proprietary, and all of Rockchip and Allwinner's offerings use either MALI or PowerVR yet their VPUs have full source (reverse engineered in the case of Allwinner).

This processor, which will be quad core dual issue 800mhz RV64GC and capable of running full GNU/Linux SMP OSes, with 720p video playback and embedded level 25fps 3D performance in around 2.5 watts at 28nm, is designed to address that imbalance. Links and details on the Libre RISC-V SoC wiki.

The real question is: why is this project the only one of its kind, and why has no well funded existing Fabless Semiconductor Company tried something like this before? The benefits to businesses of having full source code are already well-known.

dryriver writes: If you had asked someone doing 3D graphics seriously back in 2000 what 3D technology will look like two decades away in 2019, they might have said: "Most internet websites will have realtime 3D content embedded or will be completely in 3D. 3D Games will look as good as movies or reality. Everyone will have a cheap handheld 3D scanner to capture 3D models with. High-end VR headsets, gloves, bodysuits and haptics devices will be sold in electronics stores. Still and video cameras will be able to capture true holographic 3D images and video of the real world. TVs and broadcast TV content will be in holographic 3D. 3D stuff you create on a PC will be realtime -- no more waiting for images to slowly render thanks to really advanced new 3D hardware. 3D content creation software will be incredibly advanced and fast to work with in 2019. Many new types of 3D input devices will be available that make working in 3D a snap."

Except of course that that in the real 2019, none of this has come true at all, and the entire 3D field has been stagnating very, very badly since around 2010. It almost seems like a small army of 3D technology geniuses pushed and pushed 3D software and hardware hard during the 80s, 90s, 2000s, then retired or dropped off the face of the earth completely around 10 years ago. Why is this? Are consumers only interested in Facebook, YouTube, cartoony PlayStation graphics and smartphones anymore? Are we never going to see another major 3D technology innovation push again?

"While Linux-preloaded laptops have been available for years from smaller companies, and have represented a fraction of their own sales with the much-admired XPS 13 developer model, Dell now offers a range of Precision models pre-installed with Ubuntu Linux," writes Slashdot reader Freshly Exhumed. Phoronix reports: At the start of May Dell announced an Ubuntu Linux option for their entry-level ~$700 Precision laptop while now they are closing out May by offering up Ubuntu 18.04 LTS on their higher-tier Precision laptop models. Ubuntu Linux has landed for the rest of Dell's current generation Precision mobile workstation line-up with support for the Precision 5540, 7540, and 7740. The Precision 5540 offers options of Xeon E or 9th Gen Core CPUs with up to 64GB of RAM and options for a NVIDIA Quadro T2000. The Precision 7540/7740 meanwhile are more powerful mobile workstations with supporting up to 128GB of ECC RAM and latest generation processors. The Precision 7740 model can also accomodate NVIDIA Quadro RTX 5000 series graphics. Additional details can be found via this blog post by Dell's Barton George.

MojoKid writes: What do you think graphics cards will look like in the next decade and a half? Intel wanted to know that as well, so it commissioned designer Cristiano Siquiera to give us a taste of what graphics cards might look like in the year 2035. Siquiera, the original talented designer that brought the first set of Intel Odyssey GPU renders not long ago, focused primarily on the fan/shroud designs and what innovations could be fostered in the coming years. He was tasked with thinking far beyond current design conventions, materials and cooling technologies in current-gen graphics cards, and to envision new designs that could employ technologies and materials not even invented yet. One concept, called Gemini, shows an ionic-based cooling system that isn't too far beyond the realm of feasibility. Yet another design, called Prometheus, showcases top edge-mounted display readout that could also be fairly easily employed with flexible OLED display technology. Intel also just launched a new Graphics Command Center driver package today, which offers more customization, better control of power and cooling and one-click game optimization for Intel GPU-enabled systems.

While Intel is expected to detail its upcoming 10nm processor, Ice Lake, during its Tuesday keynote here at Computex, the company is already making one bold claim -- that Ice Lake's integrated Gen11 graphics engine is on par or better than AMD's current Ryzen 7 graphics. From a report: It's a bold claim, and one that Ryan Shrout, a former journalist and now the chief performance strategist for Intel, said that Intel doesn't make lightly. "I don't think we can overstate how important this is for us, to make this claim and this statement about the one area that people railed on us for in the mobile space," Shrout said shortly before Computex began. Though Intel actually supplies the largest number of integrated graphics chipsets in the PC space, it does so on the strength of its CPU performance (and also thanks to strong relationships with laptop makers). Historically, AMD has leveraged its Radeon "Vega" GPUs to attract buyers seeking a more powerful integrated graphics solution. But what Intel is trying to do now, with its Xe discrete graphics on the horizon, is let its GPUs stand on their own merits. Referencing a series of benchmarks and games from the 3DMark Sky Diver test to Fortnite to Overwatch, Intel claims performance that's 3 to 15 percent faster than the Ryzen 7. Intel's argument is based on a comparison of a U-series Ice Lake part at 25 watts, versus a Ryzen 7 3700U, also at 25 watts.

AMD CEO Lisa Su today unveiled news about its chips and graphics processors that will increase pressure on competitors Intel and Nvidia, both in terms of pricing and performance. From a report: All new third-generation Ryzen CPUs, the first with 7-nanometer desktop chips, will go on sale on July 7. The showstopper of Su's keynote was the announcement of AMD's 12-core, 24-thread Ryzen 9 3900x chip, the flagship of its third-generation Ryzen family. It will retail starting at $499, half the price of Intel's competing Core i9 9920X chipset, which is priced at $1,189 and up. The 3900x has 4.6 Ghz boost speed and 70 MB of total cache and uses 105 watts of thermal design power (versus the i9 9920x's 165 watts), making it more efficient. AMD says that in a Blender demo against Intel i9-9920x, the 3900x finished about 18 percent more quickly. Starting prices for other chips in the family are $199 for the 6-core, 12-thread 3600; $329 for the 8-core, 16-thread Ryzen 3700x (with 4.4 Ghz boost, 36 MB of total cache and a 65 watt TDP); and $399 for the 8-core, 16-thread Ryzen 3800X (4.5 Ghz, 32MB cache, 105w).

Nvidia today unveiled the tech behind new RTX Studio laptops, which can provide desktop-level computing performance for laptop users. From a report: Aimed at creators, the machines are targeted at independent artists who are fueling growing fields like social media, digital advertising, and 3D development. Nvidia says these laptops can deliver up to seven times the performance of a MacBook Pro. The 17 new laptop models from seven manufacturers, powered by a range of Nvidia GeForce and Quadro RTX graphics processing units (GPUs). The ultra-long battery life and stability when using newly developed Nvidia Studio Drivers.

The Laptops that meet the highest qualifications for creative capabilities will be badged RTX Studio. That will help creators to easily identify the right hardware to meet their demands. These Quadro and GeForce RTX-based laptops are purpose-built for GPU-accelerated content creation. The laptops feature the new Quadro RTX 5000 mobile GPU and GeForce RTX 2080, 2070 and 2060 GPUs. Quadro RTX 5000-based laptops are the world's first with 16GB of graphics memory, enabling advanced multi-app creative workflows and use of large 3D models that previously were not possible while on the go, Nvidia said. [...] RTX Studio laptops will be available starting in June from top computer makers, including Acer, Asus, Dell, Gigabyte, HP, MSI, and Razer. Pricing starts at $1,600 and will vary based on partner designs, features, and region.

Sony and Microsoft, bitter rivals in the video game console wars, will team up in on-demand gaming to better compete with newcomers like Google as the industry's main battlefield looks poised to shift to the cloud, news outlet Nikkei reported Thursday. From a report: Sony President and CEO Kenichiro Yoshida has signed a memorandum of understanding with Microsoft CEO Satya Nadella on a strategic tie-up. While details have yet to be hammered out, the partnership will center on artificial intelligence and the cloud. The latter category includes plans for joint development of cloud gaming technology. While this market is expected to grow as ultrafast fifth-generation wireless gains traction, such services require much processing power on the provider's end to deliver games with high-quality graphics and minimal lag. Sony and Microsoft plan to leverage the American computing behemoth's data centers for this purpose. The two companies, along with Nintendo, long dominated the gaming landscape. But the rise of mobile gaming has brought competition from such other players as China's Tencent Holdings, which publishes the mobile version of the wildly popular PlayerUnknown's Battlegrounds (PUBG). Press release: Sony and Microsoft to explore strategic partnership.

Ars Technica's Kyle Orland reports that Brazilian ROM hacker Vitor Vilela has released a ROM patch for the hit arcade game Gradius III, creating a new, slowdown-free version of the game for play on SNES emulators and standard hardware. "In magazine screenshots, the game's huge, colorful sprites were a sight to behold, comparable to the 1989 arcade original," writes Orland. "In action, though, any scene with more than a handful of enemies would slow to a nearly unplayable crawl on the underpowered SNES hardware." From the report: The key to Vilela's efforts is the SA-1 chip, an enhancement co-processor that was found in some late-era SNES cartridges like Super Mario RPG and Kirby Super Star. Besides sporting a faster clock speed than the standard SNES CPU (up to 10.74 Mhz versus 3.58 Mhz for the CPU), SA-1 also opens up faster mathematical functions, improved graphics manipulation, and parallel processing capabilities for SNES programmers.

The result, as is apparent in the comparison videos embedded here, is a version of Gradius III that Vilela says runs two to three times faster than the original. It also keeps its silky smooth frame rate no matter how many detailed, screen-filling sprites clutter the scene. That's even true in the game's notorious, bubble-filled Stage 2, which is transformed from a jittery slide show to an amazing showcase of the SNES' enhanced power. As if that wasn't enough, the patch even slashes the game's loading times, cutting a full 3.25 seconds from the notably slow startup animation. Vilela notes that the lack of slowdown "makes it incredibly super difficult" and even suggests that "some arcade segments of the game do not look RTA (real-time action) viable with SA-1. But we shouldn't underestimate the human capabilities."
