We can visualize resource starvation using an elaborate rendition of the Dining Philosophers Problem. This classic metaphor of resource allocation among processes was first introduced in 1971 by Edsger Dijkstra in his paper "Hierarchical Ordering of Sequential Processes." It's been a model and universal method for verifying theories on resource allocation ever since. The metaphor goes like this: There are three well-known philosophers in an Asian bistro. Dinner is served but they are only given three chopsticks because the restaurant's supply truck has been stuck in a snow storm for a couple of days. Naturally each philosopher needs two chopsticks to eat his dinner and each is protected from interference while he uses a chopstick. Plato skipped lunch that day and insists that he should have priority or else he'll faint. If he doesn't give up his chopsticks, the other ... (more)

Oracle Buys Sun

Oracle and Sun Microsystems announced today they have entered into a definitive agreement under which Oracle will acquire Sun common stock for $9.50 per share in cash. The transaction is valued at approximately $7.4 billion, or $5.6 billion net of Sun's cash and debt. "We expect this acquisition to be accretive to Oracle's earnings by at least 15 cents on a non-GAAP basis in the first full year after closing. We estimate that the acquired business will contribute over $1.5 billion to Oracle's non-GAAP operating profit in the first year, increasing to over $2 billion in the second year. This would make the Sun acquisition more profitable in per share contribution in the first year than we had planned for the acquisitions of BEA, PeopleSoft and Siebel combined," said Oracle President Safra Catz . "The acquisition of Sun transforms the IT industry, combining best-in-class... (more)

The Oracle Sun Repercussion Discussion Begins

I just started following sfearthquakes on twitter, a useful service that provides the scoop whenever we get a temblor in norcal. If it followed biz earthquakes in Silicon Valley, it'd be reporting on a magnitude 7.0 event, maybe higher, today. For the repercussions from the Oracle Sun deal have just begun, and there are several fault lines along which major aftershocks could no doubt occur. The major threads in the repercussion discussion are: * What is the future of MySql? John Dvorak was all over this angle more than a year ago, with a column that at the time sounded, frankly, paranoid, but which now looks incredibly brilliant and prescient: http://bit.ly/15lYnG. (As he said in a twitter post today, "not to brag, but I nailed something here.") * Will Oracle now get real close to HP, and provide a blockbuster competitor to IBM? ZDNet's Dana Gardner has thought this and o... (more)

MySQL Ace To Run Eucalyptus

Eucalyptus Session at Cloud Expo Mårten Mickos, the guy who sold MySQL to Sun for a billion dollars, has got himself another company. Now all he has to do is find another sucker like Sun. Mårten, who wouldn't be Mårten without that cute little Finnish doohickey over his name, has been named CEO of Eucalyptus Systems, the open source private cloud start-up. Woody Rollins, who was CEO, has morphed into the company's CFO. Since leaving Sun and MySQL last year, Mårten has been at Benchmark Capital, which backed MySQL, as entrepreneur-in-residence trying to spot his next opportunity. As it happens Eucalyptus is a Benchmark investment. Benchmark led its $5.5 million first round. Mårten says that while he was at Benchmark he asked around and people identified only two real hot buttons: the cloud and the mobile Internet. Both of them are gonna be massively big, but he fe...

Federal Cloud Computing Heating Up !

OpenXava 3.1.3: Productivity and Flexibility for Java EE

OpenXava 3.1.3 is a framework to develop Java Enterprise applications in a different way: OpenXava avoids MVC. It's a JPA Application Engine in that you provide only your POJOs annotated with JPA and you obtain an application ready for production. Productivity With OpenXava, you only need to write your model, POJOs with annotations. You do not need to write the view, and the controller (for CRUD, printing, etc) is reused. That is, you only write a class as this one: @Entity public class Teacher { @Id @Column(length=5) @Required private String id; @Column(length=40) @Required private String name; // Getters and setters } And you have an application (see it here) for CRUD, report generation in PDF, export to Excel, searching, sorting, validations etc. You only need to write a simple Java class, no XMLs, no JSPs and no code generation. OpenXava is not only for writing simple... (more)

Interviewing Java Developers With Tears in My Eyes

During the last week I had to interview five developers for a position that required the following skills: Flex, Java, Spring, and Hibernate.  Most of these guys had demonstrated the 3 out of 10 level of Flex skills even though each of them claimed a practical experience on at least two projects. But this didn’t surprise me – Flex is still pretty new and there is only a small number of developers on the market who can really get Flex things done. What surprised me the most is a low level of Java skills of most of these people. They have 5-8 years of Java EE projects behind their belts, but they were not Java developers. They were species that I can call Robot-Configurator.  Each of them knew how to configure XML files for Spring, they knew how to hook up Spring and Hibernate and how to map a Java class to a database entity. Some of them even knew how to configure laz... (more)

Oracle Takes Out Ad to Sun Customers

Oracle bought a hard-to-miss piece of the front page of the Wall Street Journal Thursday to run an ad apparently in hopes of arresting the increasing erosion in Sun’s server business. The bulleted ad is addressed to Sun customers and says Oracle “plans to spend more money developing Sparc than Sun does now; spend more money developing Solaris than Sun does now; have more than twice as many hardware specialists selling and servicing Sparc/Solaris systems than Sun does now; [and] dramatically improve Sun’s hardware performance by tightly integrating Oracle software with Sun hardware.” Then, Oracle CEO Larry Ellison tells IBM, which claims to be running off leery Sun customers, that “We’re in it to win it. IBM, we’re looking forward to competing with you in the hardware business.” Presumably this manifesto is Larry’s way of saying he meant what he said when Oracle’s p... (more)

DMTF Standardizes CIM Policy Language for Managing Computing Resources

Distributed Management Task Force (DMTF) has announced the release of its Common Information Model Simplified Policy Language (CIM-SPL) standard. CIM-SPL provides a standard language for writing system management policies based on CIM profiles, enabling IT personnel to more effectively manage their computing resources. With this standard, IT administrators are able to define rules and allocate resources within their computing systems, provide a foundation for automated systems management in distributed environments and support more efficient systems management. CIM-SPL can be used with any CIM-based implementation, including those comprising DMTF’s DASH, SMASH and VMAN initiatives. “CIM-SPL is critical for enabling organizations to take full advantage of DMTF standards for effective, interoperable IT management,” said Winston Bumpus, DMTF president. “Because CIM is ...

It’s Payback Time for Oracle & Sun

Oracle Journal on Ulitzer On Thursday or Friday Microsoft is going to step out of the European Commission's dock and point an accusing finger at somebody else for a change. It's supposed to testify at the closed-to-the-press hearing in Brussels where Oracle and Sun hope to convince the EC to stop worrying about Oracle rolling over on MySQL and smothering the thing if it acquires MySQL's owner, the sinking Sun Microsystems. Microsoft will be there to help catalogue all the anti-competitive reasons why the Commission shouldn't fall for Oracle's siren song. It's not just that Oracle has posed MySQL as a competitor to Microsoft's SQL Server rather than its own database. It's also payback time for Oracle and Sun pushing the Justice Department to bring the antitrust suit against Microsoft that opened the floodgates to Microsoft being heaped with lèse majesté abuse ever si...
