The 0.7 version of the Visopsys desktop operating system has been released. "More than four years in the making, this is a major new release offering an updated look and a number of new features, including JPEG image support, image resizing, 64-bit disk support, UDF (DVD) filesystem support, and GPT partition table support, as well as lots of new icons, wallpaper images, and file browsing functionality. New administrative applications and functionality have been added, and the ATA/IDE driver has been enhanced, including the ability to better support backwards-compatible SATA controllers. FPU context saving has been improved, and a number of tweaks and bug fixes are also included."
"Nokia Conversations caught up with Nokia's CTO Rick Green at this years Mobile World Congress being held in Barcelona and asked him about the future of Symbian, MeeGo and Qt, as you all know a radical change is coming to Nokia's strategy soon with the announcement of the new partnership with Microsoft, on Friday. A partnership that has been leaving Symbian and MeeGo users and developers alike with mixed feelings as to the future of these two OSs"
Okay, source material is more than 10 years old so this is not exactly news, but I think it's interesting anyway. This BeOS promotional video is a good reminder of how powerful modern hardware truly is, what hardware should be needed for light computer use, and how laughable modern desktop&mobile OSs are as far as performance is concerned. Here are part 1 and part 2 on YouTube.
"A lot of modern Linux distributions created with desktop users in mind go out of their way to be user friendly. Ubuntu, Mint, openSUSE, Fedora - and many more. It is a sign of how desktop Linux has matured that even non-techy types can get a fully featured and easy-to-use open source operating system up and running in not much time at all. The creators of CrunchBang Linux, however, haven't quite gone in the same direction."
"PCLinuxOS is a great distro for individuals who favor rolling updates, performance, and a dedicated community. If you're a first-time Linux user or if you favor aesthetics over technological prowess, better choices are available."
"Yesterday, Video Electronics Standards Association (VESA), the organization behind several display interfaces, has refreshed the DisplayPort Embedded standard, also known as eDP for short. The updated standard now includes a new Panel Self-Refresh feature that was developed to save system power and further extend battery life in portable PC systems. This was detailed to us during CES when we visited the DisplayPort booth at CES."
So the writing is on the wall. In a very bold move, Nokia's new CEO, Stephen Elop, has decided to fully ditch Nokia's migration plan for the past few years and have the company embrace his former employer's operating system, Windows Phone 7, instead. This noticeably implied getting rid of two competitors, Symbian and the upcoming MeeGo, which were both put on the road to slow death. This article aims at saying goodbye to an old citizen of the mobile space who's now heading to its grave: Symbian. (Warning: Rant ahead)
"While Nokia's CEO Stephen Elop has steered the company into a Microsoft future, not everyone is happy about it. Workers have walked out in Finland, and now a group of shareholders is planning a new strategy called "Nokia Plan B". The new plan has been formulated by a group of young Nokia shareholders who all have experience working for the company. None of them are happy with the decision to embrace Microsoft, and all of them plan to challenge the decision and strategy going forward."
"Manu Sporny, founder and CEO of Digital Bazaar, has decided to use GitHub to store a project of a nature. Rather than a piece of software, he is listing his own genetic data as an open source project. He has released all his rights to the data and made around 1 million of his genetic markers public domain."
"According to the original release schedule, the final release of Ubuntu 11.04 "Natty Narhwal" on 28th April was to be preceded by a Release Candidate on 21st April. Release Candidate has been scrapped and in its place, the Release Team has added a second beta on 14th April. The changes has been necessitated by the fact that 21st April is just before Easter and, so, many developers and testers would be unavailable during the time."
GTK+ 3.0 has been released two days ago. This major release includes a large number of improvements, including a full switch from the old X11 drawing API to cairo for rendering, a switch to XorgInput2 for more flexible input device management, and a new theming API sporting a CSS-like syntax for theme configuration.
Here's some very interesting analysis of why dropping Symbian or MeeGo for Android or Windows Phone 7 would be the closest thing to brand suicide which Nokia could do now.
So you have taken the test and you think you are ready to get started with OS development? At this point, many OS-deving hobbyists are tempted to go looking for a simple step-by-step tutorial which would guide them into making a binary boot, do some text I/O, and other "simple" stuff. The implicit plan is more or less as follow: any time they'll think about something which in their opinion would be cool to implement, they'll implement it. Gradually, feature after feature, their OS would supposedly build up, slowly getting superior to anything out there. This is, in my opinion, not the best way to get somewhere (if getting somewhere is your goal). In this article, I'll try to explain why, and what you should be doing at this stage instead in my opinion.
Nokia Beta Labs are currently experimenting with a new kind of lock screen for touchscreen Symbian phones. Called Nokia Bubbles, this lock screen "offers a new way to achieve a bunch of different interactions and access functionality with a load of bubbles floating around on your handset's touchscreen."
ChibiOS/RT 2.2.0 has been released. The new release of this open source embedded Real Time Operating System (RTOS) includes support for multiple compilers (Cosmic, GCC, IAR, Keil, Raisonance), drivers and demos for new hardware, internal optimizations and documentation improvements.
It's recently been a year since I started working on my pet OS project, and I often end up looking backwards at what I have done, wondering what made things difficult in the beginning. One of my conclusions is that while there's a lot of documentation on OS development from a technical point of view, more should be written about the project management aspect of it. Namely, how to go from a blurry "I want to code an OS" vision to either a precise vision of what you want to achieve, or the decision to stop following this path before you hit a wall. This article series aims at putting those interested in hobby OS development on the right track, while keeping this aspect of things in mind.
A few months ago, a bounty for porting Gallium3D to Haiku was submitted. As the target sum of $2000 has been reached, what's needed now is a developer interested in doing the actual coding work. (Gallium3D is a cross-platform video driver API, on which an increasing number of open-source Linux drivers are based.)
Thinking that HP's memristors can't arrive early enough on the market? Here's competition already! A team at North Carolina State University, led by Dr Paul Franzon, has unveiled the "double floating-gate field effect transistor", a component based on the same principles as flash memory which would allow to store data for "a couple of years" in around 15 nanoseconds.
"A class action lawsuit against Microsoft has been filed in Italy by a group claiming that it's too difficult to procure a refund for the copies of Windows that come bundled in new PCs."
Today, Ken Thompson and Dennis Ritchie, the two Bell labs scientists which began creating the Unix operating system in 1969, have been named as winners of the 2011 Japan Prize for information and communications.
