VMware Server Console: Introduction to Virtualisation

"The majority of Linux users have gotten used to keeping more than one operating system on their hard disks. Most frequently the second system is a version of Microsoft Windows. Switching between the two systems tends to be irritating, especially when the secondary system is needed only once - to run an application WINE has refused to start, for example. Now we introduce the virtualization technology which allows us to run several systems on the same computer, at the same time, all under the control of one of them, called a 'host'. My examples are based on the VMware Server Console v. 1.0.3 (distributed from its manufacturer's website free of charge) running under Mandriva Linux Spring with KDE 3.5.7."

64Bit MenuetOS 0.64 Released

A new release of the 64bit version of MenuetOS has been released, MenuetOS 0.64. "MenuetOS is an operating system in development for the PC written entirely in 32/64 bit assembly language, and released under this license. It supports 32/64 bit x86 assembly programming for smaller, faster and less resource hungry applications."

Gravatar Support on OSNews

You might have noticed some user icons next to some comments today, this is because we enabled Gravatar support. Gravatar acts as a centralized identity pool where blogs, news sites (and recently Revver.com) can use their service and offer a universal icon for each unique email address. As long as you register on Gravatar with the same email address registered on OSNews, your personalized icon will be shown on OSNews (and on all other sites that support Gravatar) automatically. This is a testing period for Gravatar here at OSNews, and there are no guarantees whatsoever that the v4 version of OSNews will use that icon system or its own. It all depends on the kind of quality, stability and responsiveness we get from Gravatar's servers. So, upload your own icon at Gravatar.com and test away! Ability to turn off user icons will be built-in on v4.

Roundup of Free Operating Systems

"The Free Software community is well known for its diversity. This is most obvious at the application level, but even exists in the context of operating systems. David Chisnall takes a break from UNIX-derivatives and explores some of the more esoteric options." Note: From experience, I can say that the author's claim that "Haiku is more or less ready for their 1.0 release in terms of features" is a bit overambitious.

VMware Windows-on-a-Mac Product Close to Launch

VMware is pricing its upcoming new software to run Windows on a Mac similar to rival Parallels's software announced last week. VMware said that its Fusion software for Macintosh computers can be pre-ordered beginning Tuesday for USD 39.99, and USD 79.99 when it becomes generally available near the end of August. Parallels priced its Parallels Desktop version 3.0 at USD 79.99 when it became generally available Thursday, and USD 39.99 for users upgrading from a previous version of Parallels.

MINIX 3.1.3a Released

A minor extra release of MINIX 3.1.3 was done, called 3.1.3a, correcting some flaws in 3.1.3. "Found after release time and fixed in 3.1.3a: mkfs does not check for overflow of firstdatazone field in superblock; a missing check in rename caused moving directories to hang sometimes; autopart truncates new partitions at 4GB. If you want to create a larger partition, use part (expert mode) to do that first; and more."

EyeOS 1.0, Kolibri 0.7.0.0 Released

Kolibri 0.7.0.0 has been released. "Less than 4 months since our previous release and we are glad to give you a new one, Kolibri 0.7.0.0. There are quite a lot of changes for such a small amount of time. The kernel was modified to use a flat memory model and to support fast system calls (sysenter, syscall). There are also many other changes such as kernel configuration using external ini-file, special /sys directory, system boot screen improvements, and much more." The web operating system EyeOS 1.0 (and 1.0.1 shortly after) has also been released.

VMware Workstation Goes Rootless

"I remember the day I was interviewed at VMware. I was asked what I would do to improve Workstation, and one of the things I said was that it would be nice to make a VM go rootless. That is, pull application windows out of the VM and make them integrate well with the operating system. I wasn’t the only one. A lot of people wanted this type of feature. It’s been discussed for years, but it’s always been hard to find the manpower to do it. But competition is good, and we finally got some people on this feature. And it turned out spectacularly."

Delimited Continuations in Operating Systems

"Chung-chieh Shan and have submitted a paper on delimited contexts in operating systems and the zipper OS (which has not been formally published). Systems programmers do use contexts whether they are aware of that or not. The first version of UNIX on PDP-7 already implemented delimited continuations, in the form of co-routines between user programs and the shell. Being aware of delimited continuations may help systems programmers to better implement context switching, signal handling, etc., using the techniques developed in programming language research. It also leads to new insights, for example, that checkpointing a process and snapshotting a file system are essentially the same activity."

The Top 10 Dead (or Dying) Computer Skills

"Those in search of eternal life need look no further than the computer industry. Here, last gasps are rarely taken, as aging systems crank away in back rooms across the U.S., not unlike 1970s reruns on Nickelodeon's TV Land. So while it may not be exactly easy for Novell NetWare engineers and OS/2 administrators to find employers who require their services, it's very difficult to declare these skills -- or any computer skill, really -- dead." My Take: "C" dying should have been "x86 Assembly".

Visopsys 0.68 Released

The 0.68 release of the Visopsys OS went live today. It's a maintenance release with the usual array of tweaks and bug fixes, plus a focus on disk I/O performance; the software disk caching was re-written, and lookahead/write caching were added to the IDE driver. Another new feature is secure deletion (shredding) of files, partitions, and disks. Change log here and downloads here.

‘Win4Lin Pro Desktop 4.0 Lags Behind Free Alternatives’

"One of the oldest virtualization products, Win4Lin, is starting to show signs of aging. Win4Lin flourished in 2000, when competition was sparse and expensive. But seven years on, not only are there several virtualization products, but almost half a dozen are available for free. With no visible improvements over its previous version, Win4Lin Pro Desktop 4.0 is now outdated and outclassed."

Recoll: a Search Engine for the Linux Desktop

"Desktop search engines are all the rage these days. While Beagle may be the most popular desktop search engine for Linux, there are alternatives. If you are looking for a lightweight and easy-to-use yet powerful desktop search engine, you might want to try Recoll. Unlike Beagle, Recoll doesn't require Mono, it's fast, and it's highly configurable. Recoll is based on Xapian, a mature open source search engine library that supports advanced features such as phrase and proximity search, relevance feedback, document categorization, boolean queries, and wildcard search."

Visopsys 0.67 Released

Version 0.67 of Visopsys was released today, with all the usual bug fixes and tweaks plus two focus areas of improvement: the IDE/ATA disk driver has been 'modernized' with PCI, DMA, and 48-bit addressing support, resulting in a raw I/O performance increase of up to 700%; additionally the Disk Manager (Partition Logic) has been re-engineered and modularized to support the later addition of new disk label types, as well as improved support for MS-DOS logical partitions (moving, creating out-of-order, etc.). Downloads are here, and the change log is here.

Contiki 2.0 Released

Contiki is an open source operating system for memory-constrained networked embedded systems. Version 2.0 of Contiki has just been released. The 2.0 release is the first release from the 2.x series, which brings many new features: dynamic run-time loading and linking of standard ELF object code files; Rime, a protocol stack designed for low-power radio communication; Cooja, a Java-based network simulator for Contiki; and an updated build system that makes cross-compiling for many platforms easy. See the Contiki website for details and downloads.
