The Z88 Development Team has released a new version of the system ROM for the Cambridge Z88 portable.
It's the result of more than a years work, with many improvements and new features: ISO character set support in filenames and international dates, faster serial I/O, improved RAM applications, better responsiveness. Rock-stable software that enables to run your Z88 for many months with re-booting.
The team also outlines its plans for the future:
The next step for the coming years is to re-implement the Z88 on low-power FPGA, minimum 10 X faster CPU, 800x600 screen resolution, up to 1Gb of RAM, SD-card filing system, VGA/HDMI output, improved operating system with new Unix-like command line Shell, ELF for Z80 executables + shared libraries, and integrated Zip arching in filing system. Emulators and developer tools will also be freely available.
While common magnetic tape uses very thin, plastic-coated iron oxide, "talking rubber" uses rubber impregnated with iron oxide. Iron oxide (a form of rust) is ferromagnetic, which means in the presence of a magnetic field, the electrons in the iron oxide magnetically line up and stay that way even after the magnetic field is turned off. This allows cassette tapes to create a “track” of magnetically aligned iron oxide when the electromagnet in a cassette recorder creates a magnetic field.
But with magnetic rubber, the iron oxide is actually mixed into the rubber material; the whole band becomes ferromagnetic, instead of just the coating. According to that Bell System Journal article, this “talking rubber” could be around 1/16 or 1/8 of an inch think, whereas magnetic tape was (even in the '50s) already much thinner at 1/1000 of an inch thick.

Over the past few weeks, we've gotten notes from Verge Science readers wondering why news from the incoming Trump administration has seeped into our science coverage. I wasn't surprised: it's tempting to believe that science is apolitical. But science and politics are plainly related: science is the pursuit of knowledge, knowledge is power, and power is politics.
The scientific method consists of generating a hypothesis, attempting to disprove the hypothesis through testing, and accumulating those tests to come up with shared knowledge. And that method also contains ideology: our observed, shared world is the real world. This ideology even has a name: empiricism. An incoming president who clearly picks and chooses facts to suit his own version of the world changes the relationship between science and culture, in potentially destructive ways.
"To be taught to read - what is the use of that, if you know not whether what you read is false or true? To be taught to write or to speak - but what is the use of speaking, if you have nothing to say? To be taught to think - nay, what is the use of being able to think, if you have nothing to think of? But to be taught to see is to gain word and thought at once, and both true."Tomorrow, in a mirror, darkly.
The administration's analysis of Autosteer was more positive about its capabilities. After analyzing mileage and airbag deployment data for Model S and Model X cars equipped with Autopilot, the NHTSA concluded that "the Tesla vehicles' crash rate dropped by almost 40 percent after Autosteer installation."
Wait, you mean to tell me a computer who doesn't get sleepy or distracted and doesn't need to pee is better at keeping an eye on the road than a human?
Say it isn't so.
FAP80 is a Z80-based retro computer with a sprinkling of modern twists to make the experience of designing, programming, and debugging this computer as painless and straightforward as possible.
A lot of retro computer projects today are rooted on nostalgia, they tend to use "period correct" components to get the "feelings" right, and the result often ends up on perfboard or self-etched circuit boards, rudimentary video capacity if at all, few I/O ports, and a symphony of 74 series chips.
While there is nothing wrong with that, I wasn't around during the 80s home computer era, so I didn't have the same attachment to how things was done back then. So instead of trying to recreate the "good old days", I made the decision to liberally use modern parts to simplify the design process, as well as making this computer highly flexible and easy to program and use with very little overheads.
The creator's blog has more detailed information about the project.
With those out of the way, TASBot moved on to a similar total control run of The Legend of Zelda: A Link to the Past. After a few minutes of setup, the Zelda screen faded out, then faded back in on a bordered window with an ersatz logo for the "Super N64." Without any forthcoming explanation from the runners on stage, TASBot started apparently playing through a glitch-filled speedrun of Super Mario 64 on the Super NES, following it up with a similar glitch-filled speedrun through Valve's PC classic Portal. After that, the scene somehow transitioned to a Skype video call with a number of speedrunners speaking live from the AGDQ event through the SNES.
No one on the AGDQ stage acknowledged how weird this all was, leaving hundreds in the Herndon, VA ballroom and nearly 200,000 people watching live on Twitch temporarily guessing at what, exactly, was going on.
AGDQ (and its Summer counterpart, SGDQ) are some of my favourite events in technology, and I have the entire marathon streaming for the whole week. The TASBot block this year was, as the excerpt above describes, insane, and this article explains how they did it.
Early December of last year, I posted the rumour that Oracle was going to end Solaris development. While the company denied these rumours at the time, there still seems to be something going on.
Rumors have been circulating since late last year that Oracle was planning to kill development of the Solaris operating system, with major layoffs coming to the operating system's development team. Others speculated that future versions of the Unix platform Oracle acquired with Sun Microsystems would be designed for the cloud and built for the Intel platform only and that the SPARC processor line would meet its demise. The good news, based on a recently released Oracle roadmap for the SPARC platform, is that both Solaris and SPARC appear to have a future.
The bad news is that the next major version of Solaris - Solaris 12 - has apparently been cancelled, as it has disappeared from the roadmap. Instead, it's been replaced with "Solaris 11.next" - and that version is apparently the only update planned for the operating system through 2021.
Read into that what you will. Sounds like maintenance mode to me.
I'll almost certainly buy another MacBook, especially if future iterations can give me back the rationalization that paying so much money allows me to have the best computer. (The best for me, of course; the person who does not need to play videogames on his laptop, for example, because he is going to write a short story or record a pop song.) But in the meantime, I'm enjoying a new type of anticipation which for now only seems to be available in Windowsland: that someday, despite the funfetti working environment and Homermobile nature of the hardware, I may actually be on a path that's going somewhere not just new, but better, or at least more exciting.
Quite the enjoyable read.
There's a new form of digital censorship sweeping the globe, and it could be the start of something devastating.
In the last few weeks, the Chinese government compelled Apple to remove New York Times apps from the Chinese version of the App Store. Then the Russian government had Apple and Google pull the app for LinkedIn, the professional social network, after the network declined to relocate its data on Russian citizens to servers in that country. Finally, last week, a Chinese regulator asked app stores operating in the countryto register with the government, an apparent precursor to wider restrictions on app marketplaces.
These moves may sound incremental, and perhaps not immediately alarming. China has been restricting the web forever, and Russia is no bastion of free speech. So what's so dangerous about blocking apps?
Here's the thing: It's a more effective form of censorship.
It's almost like an operating system where you can't install applications not approved by its manufacturer is a really, really dumb idea.
The next version of Google's smartwatch operating system is slated to arrive on February 9th, according to mobile reporter Evan Blass. The leak follows last week's report that Google had notified developers of Android Wear 2.0's upcoming release so they could prepare to update apps for continued support.
I'm sure all three Android Wear users are jumping up and down with excitement.
This document gives an overview of how security is designed into Google’s technical infrastructure. This global scale infrastructure is designed to provide security through the entire information processing lifecycle at Google. This infrastructure provides secure deployment of services, secure storage of data with end user privacy safeguards, secure communications between services, secure and private communication with customers over the internet, and safe operation by administrators.Google uses this infrastructure to build its internet services, including both consumer services such as Search, Gmail, and Photos, and enterprise services such as G Suite and Google Cloud Platform.
We will describe the security of this infrastructure in progressive layers starting from the physical security of our data centers, continuing on to how the hardware and software that underlie the infrastructure are secured, and finally, describing the technical constraints and processes in place to support operational security.
This document also touches on something I always find quite fascinating - Google is, actually, an incredibly successful hardware company.
A Google data center consists of thousands of server machines connected to a local network. Both the server boards and the networking equipment are custom-designed by Google.
I have no idea how many servers Google actually owns, but this could make them one of the biggest hardware companies in the world.
axle is a small UNIX-like hobby operating system. Everything used within axle is implemented from the ground up, aside from the bootloader, for which we use GRUB. axle is a multiboot compliant kernel. axle runs C on 'bare metal' in freestanding mode, meaning even the C standard library is not included. A subset of the C standard library is implemented within axle's kernel, and a userspace version is planned. axle is mainly interfaced through a shell.
Open source, custom educational operating system. The first public alpha release is out.
The sprawling investigation into President Park Geun-hye of South Korea took a dramatic turn on Monday with word that prosecutors were seeking the arrest of the de facto head of Samsung, one of the world's largest conglomerates, on charges that he bribed the president and her secretive confidante.
Nobody should be able to escape justice - not even CEOs. I know of a few others who need to follow in Lee's footsteps.
VSI (the men and women porting OpenVMS to x86 hardware) has released an update outlining some of the issues so far in porting this old battleship of an operating system to x86 and liberating it from IA64.
This update provides a high level view of our current efforts to port OpenVMS to the Intel x86 hardware platform. The report highlights topics including: Compilers, Objects & Images, Early Boot Path, Virtual Machines, Dump Kernel, Paravirtualization, and Condition Handling.
iPhone app purchasers may sue Apple Inc over allegations that the company monopolized the market for iPhone apps by not allowing users to purchase them outside the App Store, leading to higher prices, a U.S. appeals court ruled on Thursday.
Apple bloggers obviously kneejerk straight into defence mode in response to this news, but if you actually dive into the decision, the court makes a very compelling argument as to why this case ought to be allowed to continue, that preempts all the usual terrible analogies they tend to come up with and/or parrot from the party line:
Apple argues that it does not sell apps but rather sells "software distribution services to developers." In Apple's view, because it sells distribution services to app developers, it cannot simultaneously be a distributor of apps to apppurchasers. Apple analogizes its role to the role of an owner of a shopping mall that "leases physical space to various stores." Apple's analogy is unconvincing. In the case before us, third-party developers of iPhone apps do not have their own "stores." Indeed, part of the anti-competitive behavior alleged by Plaintiffs is that, far from allowing iPhone app developers to sell through their own "stores," Apple specifically forbids them to do so, instead requiring them to sell iPhone apps only through Apple's App Store.
Instead, we rest our analysis, as compelled by Hanover Shoe, Illinois Brick, UtiliCorp, and Delaware Valley, on the fundamental distinction between a manufacturer or producer, on the one hand, and a distributor, on the other. Apple is a distributor of the iPhone apps, selling them directly to purchasers through its App Store. Because Apple is a distributor, Plaintiffs have standing under Illinois Brick to sue Apple for allegedly monopolizing and attempting to monopolize the sale of iPhone apps.
Over on Twitter, John Gruber asked me "iPhones are their own market? Does BMW have a monopoly on BMWs?" This clearly demonstrates a lack of understanding of how the car market actually works (and, quite clearly, indicates Gruber didn't even read the actual decision quoted above). In fact, exactly because car manufacturers have a de facto monopoly on their own products, they are legally obliged to open up their specifications to allow other companies to manufacture competing, off-brand parts and to allow third parties to service and maintain the cars according to the manufacturer's own specifications.
As I've argued before, there's absolutely no reason why the technology world should be treated any differently. Computers have become integral parts of our society, much like cars, and as consumers we should not be forced into relying on just one company for servicing, maintaining, and using them. It's high time we stop treating technology companies like special little flower children, and force them to grow up and become real companies with real responsibilities.
In 1999, armed with a brand new copy of Metrowerks Codewarrior and a PowerMac running Mac OS 8.5.1, I wrote a basic implementation of Minesweeper to test out the Powerplant application development environment. It's the oldest project of mine that I've kept, so I wanted to see if I could get it running again for the first time in 17 years.
There's no Swift or Objective-C code in this article but there are disk-eating koalas, deliberately misspelled cities, Zernike polynomials, Cocoa software (but not the Cocoa you're thinking of), resource forks, master pointer blocks and in the end, I finally earn the admiration of my family.
Great, entertaining story, you learn something, and it mentions BeOS. I can't think of anything that would make this story even more likely to get posted on OSNews.
The Nintendo Switch will be released March 3 worldwide for $299, Nintendo announced today during a press briefing in Tokyo.
Nintendo will sell the Switch for 29,980 yen in Japan. In Europe, the price will vary by retailer. The Switch will be available in two configurations: one with gray Joy-Con controllers, and the other with neon red and blue Joy-Con devices. Otherwise, the hardware will be the same: 32 GB of internal storage with a 720p touchscreen.
I'm somewhat curious about the hardware, somewhat interested in the new Zelda they showed off, but I'm appalled at the pricing in Europe (you'll be plonking down around €400 for the console and a game), and disappointed in the weak launch line-up and pretty meagre collection of games they showed off for the coming year.
The Mario and Zelda franchises have basically become like Call of Duty - every year, we get pots, remakes, of a new game with a few new mechanics, and that's it. There's nothing wrong with that - if people enjoy them, they enjoy them, and that's great - but I feel like Nintendo could be doing so much more than this.
As some of you may undoubtedly know, I'm a bit of a sucker for Palm OS. These past few years, I've been busy collecting ROMs for the Palm OS emulator and simulator, making sure I have all the major Palm OS releases covered. There's really not much of a reason to do this - I have working devices which are a much better option than the emulators/simulators in most cases - other than to have a complete collection I can keep around forever.
From top left to bottom right, you're looking at Palm OS 1.0, 2.0, 3.0, 3.5, 4.0, 5.3 (a Palm Zire ROM), 5.4.9 (the last released version of Palm OS available on real devices), and Palm OS 6.1.0 Cobalt (the last version of Palm OS; no 6.x device has ever been released). This is a pretty complete collection, and while it doesn't contain every released version of Palm OS, it covers the most important ones, and provides a great overview of the development of the operating system.
One important version is actually missing from this screenshot: Palm OS 5.5, whose official name is actually Garnet OS 5.5. Garnet OS 5.5 was developed by ACCESS (current owner of Palm OS and the associated IP), but was never released on or for devices - its sole function was to serve as the operating system running inside the Garnet VM. Garnet VM was a virtual machine developed to allow Palm OS applications to run on the ACCESS Linux Platform, a Linux-based mobile operating system that never gained any traction; no ALP devices were ever released.
As some of you may remember, Garnet VM was also released for Nokia's Maemo. I have a Nokia N900 (maybe even two) that can run Garnet VM, and while it's no longer available from ACCESS itself, it's easy to find all around the web if you know where to look. I'm not sure if my N900 is properly set up (I think it is), but it would be trivial for me to install Garnet VM on it and play with it.
So, between my Palm/CLIÉ devices and all these emulators/simulators, every major Palm OS version seems covered, right? Well, no - not entirely. There's quite a few exotic devices, such as the AlphaSmart Dana, the TapWave Zodiac, or the Fossil Palm OS smartwatch, but those are disproportionately hard to come by. Setting those aside, I thought I had all my bases covered.
As it turns out, and entirely unbeknownst to me, ACCESS actually released the Garnet VM for Linux and Windows. After coming to the conclusion that this piece of software was entirely impossible to find online (try it), q3hardcore came to the rescue once again, and uploaded his or her copy of the package online. Questionable legality aside, I didn't have to think twice.
The purpose of the Garnet VM for Linux and Windows was to allow Palm OS application developers to test their Palm OS applications to see if they would run on the Garnet VM included in the ACCESS Linux Platform, and make changes if needed.
This Garnet VM is an amazing piece of technology. It's the Palm OS userland - version 5.5.0 - running on a Linux kernel running on an ARM emulator running on Windows or Linux. The ARM emulator in question is called Janeiro, and it emulates a Zylonite (PXA320) development board, revision B1. As it boots up, there's zero indication that it's running a Linux kernel - the X 'cross' appears briefly (at least, it looks like the X cross), but that's it.
The major difference between the Garnet VM and the Palm OS 5.x and 6.x simulators is that while the simulators run x86 Palm OS, Garnet VM runs an ARM Palm OS userland atop an ARM Linux kernel. This means - at least, in theory - that ARM Palm OS applications should run decently well on Garnet VM, something you can't do with the Palm OS simulator, because they would need to be recompiled to x86. I say 'in theory', because the Garnet VM documentation notes that not all Palm OS libraries and components are present, and that only "well-behaved" applications are compatible.
I've only had access to the Garnet VM for Windows for a short while, and I haven't yet had the time to really dive into it. For instance, I've yet to figure out how to get applications to run inside the VM, since the usual methods don't seem to want to cooperate. I'll spend some more of my free time on playing with it over the coming weeks to better figure out how it all works.
In any event, the Garnet VM for Windows and Linux is a unique piece of computing history, and I am absolutely delighted to be able to add it to my collection of Palm OS memorabilia. I've briefly considered zipping up all the emulators, simulators, and ROMs I have into a nice preconfigured, documented package for people to play with, but that's not something I can do for obvious copyright, trademark, and patent reasons. Most of this stuff isn't particularly hard to find, but it does require a bit of Palm experience to put it all together and document it. I don't think I'll ever get permission from ACCESS, so that's the end of that idea.
Still, I think it's important that I continue to collect these Palm OS ROMs and emulators/simulators, because as the years go by, more and more Palm devices will start to break down or get lost, leaving us without to ability to experience this amazingly lovable operating system.
A year ago, we set out to explore what web browsers might look like in years to come. Now, you can try Opera Neon - a concept browser that gives you a glimpse into the future of desktop browsers.
A little too quirky for my tastes, but hats off to Opera for trying out new approaches -browsers feel dead and lifeless at the moment.
I don't think we'll ever see Half-Life 2: Episode 3, and the cliffhanger conclusion makes Half-Life 3 unlikely as well. The best chance of Half-Life getting a second wind will likely come if J. J. Abrams and Bad Robot can get the Half-Life film to screen. If that comes to fruition, and it doesn't bomb like almost every game movie before it, maybe, just maybe there's a chance of Gordon Freeman’s story continuing. Roll your eyes at the movie mention if you want, but how else will this franchise get a pulse again?
The interview you are about to read sheds some insight into how Valve works as a developer. Yes, someone at Valve could just say, "Let's make another Half-Life" and do it, but there are huge risks and hurdles involved in doing that. Prior to this interview, I was in the camp of, "Valve just doesn't get it." Now I'm in the camp of, "Valve is probably doing the right thing, but it's disappointing."
This interview opened my eyes to Valve's unique way of developing games, but also provided a bit of closure for someone who wants to see Half-Life continue. In the days before publishing this story, I reached out to Valve one last time for comment, but my request went unanswered. Without further delay, here's the interview.
This is a must-read.
