Solaris and OpenSolaris

"Few overarching conclusions can be drawn from the limited results of this study. Certainly, there are situations in which the Solaris/RAID-Z1 configuration appears to outperform the Ubuntu/RAID-5 configuration. Many questions remain regarding the large discrepancy in CPU usage for small-file operations. Likewise, the Ubuntu/RAID-5 configuration appears to perform slightly better in certain situations, though not overwhelmingly so. At best, under these default configurations, one can say that overall the Solaris configuration performs no worse, and indicates that it might perform better under live operating conditions. The latter, though, is largely speculation." - ovigia from Bookmarklet

"One of the best references for Linux and UNIX system administrators over the years has been the "Handbooks" (either Linux Administration Handbook (LAH) or UNIX System Administration Handbook (USAH) at various points). But the last edition was published in 2000 (as USAH), and included information on then-current Red Hat Linux 6.2 and FreeBSD 3.4. A new, updated version, UNIX and Linux System Administration Handbook, Fourth Edition (ULSAH), is due out any day now, and the principal authors, Evi Nemeth, Garth Snyder, Trent R. Hein, and Ben Whaley, agreed to answer some questions for LWN readers. Below are their answers on the book, the impact of Linux, the future for UNIX and Linux, and more." - ovigia from Bookmarklet

"The London Stock Exchange has completed the first “dress rehearsal”, a test with its customers online, of a new Linux-based system due to replace Microsoft-centric architecture. The Millennium Exchange system, based around Linux and Sun Solaris Unix, and using Oracle databases, will replace the Microsoft.Net-basedTradElect platform on the main stock exchange on 1 November, and is intended to be one of the fastest exchange systems in the world with trading times of 0.125 milliseconds." - ovigia from Bookmarklet

"Until then, the exchange will continue to work with the outgoing TradElect system, based on Microsoft .Net architecture and updated by Accenture in 2008 for £40 million. In July, it booked £25.3 million depreciation costs on TradElect. TradElect, the subject of much controversy in recent years, had suffered a series of high-profile outages, the worst being an eight hour downtime in 2008. " - ovigia

"Solaris holds a special place in my heart. It was my first taste of UNIX, back in my school days, and I probably wouldn't have become involved with the Linux community if I hadn't been searching for a free version of "this UNIX thing" so I could practise my shell scripting at home. I was thrilled when Sun announced they were releasing OpenSolaris for the community to play with, even if it was several years too late to help me with my homework. And I was very disappointed when Oracle executed OpenSolaris earlier this year. Fortunately for Solaris fans the OpenIndiana project is picking up where Sun left off. I had been itching to try a new version of OpenSolaris since February (when the last release was scheduled) and so I quickly grabbed the newly launched OpenIndiana, development build 147." - ovigia from Bookmarklet

"OpenIndiana is a continuation of the OpenSolaris operating system. It was conceived during the period of uncertainty following the Oracle takeover of Sun Microsystems, after several months passed with no binary updates made available to the public. The formation proved timely, as Oracle discontinued OpenSolaris soon after in favour of Solaris 11 Express, a binary distribution with a more closed development model to debut later this year. OpenIndiana is part of the Illumos Foundation, and provides a true open source community alternative to Solaris 11 and Solaris 11 Express, with an open development model and full community participation." - ovigia from Bookmarklet

"On next Tuesday 14th, the Illumos Foundation will reveal the details of OpenIndiana. OpenIndiana is to be a server or desktop operating system based on Illumos, the recently created fork of OpenSolaris. Project Lead, EveryCity's Alisdair Lumsden said that, "this announcement will deliver the distribution the community has long sought after."" - ovigia from Bookmarklet

"As it had previously threatened, the OpenSolaris Governance Board (OGB) has now resigned. The dissolution motion was proposed and passed unopposed in a fourteen minute long meeting of the OGB." - ovigia from Bookmarklet

"According to Garret D'Amore, Illumos project leader, the recently launched derivative is beginning to diverge from OpenSolaris. D'Amore has noted in his blog that he believes the last commit to Oracle's public repository for ON, the core of OpenSolaris, has been made. According to a leaked memo revealed earlier this week, Oracle are ceasing open development of Solaris and will discontinue OpenSolaris, migrating users to Solaris Express 11." - ovigia from Bookmarklet

"At the company's strategy update, Oracle outlined the future for Solaris 11, but said nothing about OpenSolaris. Oracle's John Fowler says that Solaris 11 will be a major upgrade to key components, such as networking stacks, threading, file systems, package management and maintenance. A focus on scalability would also be incorporated in preparation for the next generation of hardware, like the 128 core, 16,384 thread system with 64TB of memory that Oracle is currently developing. Solaris 11 is expected around the second half of 2011." - ovigia from Bookmarklet

"Brian Cantrill, who recently left Oracle and joined Joyent, said the announcement was "Terrific news for OpenSolaris ... This will give us the power to fork the system in innovative ways. I personally am thrilled, we at Joyent are thrilled. We owe a debt of gratitude to Garrett". Simon Phipps, OSI board member and ex-Sun/Oracle, noted that the project was similar to the IcedTea effort for OpenJDK, which positioned itself downstream of OpenJDK and developed open source replacements for the closed source elements of OpenJDK; this has in turn allowed OpenJDK to be more widely used and, in some Linux distributions, it has become the default Java implementation. In a similar way, he hopes to see Illumos become the default open source implementation of OpenSolaris." - ovigia from Bookmarklet

"In an act of desperation, the OpenSolaris governing board (OGB) has issued an ultimatum to Oracle. The company must nominate a contact person able to take decisions regarding OpenSolaris by the 16th of August or the board will dissolve and relinquish control of OpenSolaris to Oracle." - ovigia from Bookmarklet

A Sun era uma empresa que pela sua posição não dominante no mercado não constituia qualquer risco para o software livre. Pelo contrário, até ganhava com ele. A Oracle não vê qualquer necessidade do software livre, que constitui um encargo. Esta é a diferença crucial entre mercados livres e capitalismo. Este último não tolera a concorrência de modelos alternativos. É como uma espécie de eucalipto ;) Seca tudo à sua volta. - Miguel Caetano

"Once upon a time the successor to OpenSolaris 2009.06 was supposed to be OpenSolaris 2010.02 and then it became OpenSolaris 2010.03 with a release date in March and then who knows what happened. There hasn't been an update to the OpenSolaris operating system now in a year nor has there been any communication at all to developers or end-users by Oracle about their plans after taking over Sun Microsystems. All indications were that Oracle would at least deliver an OpenSolaris update in 2010'1H, but it looks like that won't happen." - ovigia from Bookmarklet

"Can a FOSS company reasonably expect to be worth a billion dollars someday? Should it even try to? No, suggests Slashdot blogger Darren Baker.

"The problem, rather, is that "monopolies like M$ do not like to share the wealth," Pogson explained. "Would not the world be a better place if M$ were split into a bunch of $billion FLOSS projects? How many could you make, 40?" Of course, "the way FLOSS works, we don't really need $billion companies," he added. "A few hundred million works just fine. You can distribute a lot of copies for free with bittorrent, you know."" - ovigia

"Specifically, in North America "things have changed so much over the last 50 years that it's gone from being a Work-to-Live society to a Live-to-Work society," Baker explained.

Companies are so large now that they have the breadth and girth to hold our governments hostage with threats of job cuts."" - ovigia

"LinuxInsider: Overall, when it comes to security, do you think openness is a virtue or a vice? Ransbotham: Overall openness is a virtue, but not without elements of vice. The challenge for open source communities is to maintain the benefits while mitigating the downsides. My recent research points out one part of the vulnerability process, where attackers may benefit from seeing open source, and tries to quantify that benefit. I think we need more research and analysis to understand better how these virtues and vices combine. Open source communities can then use that information to respond to the ever-changing threat environment." - ovigia from Bookmarklet
