Easy Eclipse Distro

For all you eclipse fans, there is a good distro for eclipse available (called Easy Eclipse) aimed at making the installation easier for eclipse. It has a pre-zipped bundle of plugins and all version dependencies are taken care of plus there are separate versions depending on what you need eclipse for (making Swing/SWT apps, server-side programming, mobile application development, etc). In my own experience, knowing what plugins to install to say start/stop tomcat or weblogic server or to support javascript or xslt editing is a manual process and complicated by the issues involved with version dependencies. With Easy Eclipse, the job of identifying the right plugins has already been taken care of and you can start using eclipse in all its glory right after the install.

12/27/06: I used the EasyEclipse Server Java 1.2.1 distro yesterday for setting up my development environment for learning EJB 3.0 with JBOSS 4.0.5 GA. And this distro installs JBoss Eclipse IDE with Eclipse 3.2.1 platfo…

Joy of Tech - Linux Lovers

Image
When i bought my present PC for home, it came with Turbo Linux distribution. The PC is a Compaq make with AMD XP 2400+ processor. It was 2004 July when i bought it. I first decided to keep the Turbo Linux distribution. Later i experimented with a few more distributions (Fedora Core 2, SuSE 10.x, RH 9). It was a good setup and i was gradually getting used to the habit of doing common things from command line (like playing music using mplayer). It was a dream like phase for me as i saw the developer tools which came free (vi, xemacs, and GNU GCC toolchain, linux kernel sources) and felt very passionate about someday becoming a linux systems programmer geek :). Those days i used to be learning unix systems programming, linux kernel development and fundamentals of embedded systems programming - all of it in self-taught way. I read some books then like - Linux Kernel Development by Robert Love, Advanced Programming in the Unix Environment (almost completed it) by R Stevens, An Embedded Sof…

SCBCD likely to be updated for EJB 3.0

On a post in Javaranch.com, Valentin Crettaz commented that SCBCD is likely to be updated for EJB 3.0 and the new exam will be available by early next year (ie 2007). Of late, many have posted on Javaranch on whether its wise to take the present SCBCD exam (viz aligned to J2EE 1.3 version of EJB Spec 2.0) or wait for the upgrade when the exam aligns with Java EE 5.0 version of EJB Spec 3.0. Now the same question is being asked about the present SCDJWS 1.4 exam (aligned to J2EE 1.4 version of WS specs). Sun has made some major architectural changes to the erstwhile JAX-RPC 1.1 (so much so that the new stack is called JAX-WS 2.0) and also the other standards have evolved in the due course (like SOAP 1.1 obsoleted bySOAP 1.2, WSDL 1.1 obsoleted by WSDL 2.0 etc). But experts at Javaranch feel that an upgrade to the present SCDJWS 1.4 will take some time (it may even be upgraded by Java EE 6.0).
In my opinion, those planning to take SCBCD 1.3 may want to wait for the newer version of t…

$100 MIT Laptop

Seen above is the $100 laptop for kids in the third world countries. Dont you find its amazing ! And our Indian govt. said no to it.

More info regarding this laptop can be found at : http://laptop.media.mit.edu/.

My views: In my opinion, rather than simply writing off the $100 laptop the indian govt could have atleast introduced these to those children who dont sit under trees and do have a proper school where they could have used the laptop as a device to learn from better (and more funnier than their books). Many children in india leave education only because they never found studies interesting enough. I have seen child labors in my own state Bihar, India, where they chose to opt out of school just because they did not find it fun and so spent time away from school bunking classes. Providing those children with an interesting electronic device and showing them how to use it is all that will be needed to get them started using it. Also even if 10% of children pick up the basics, the k…

Reading of SNMP, SNMPv2, SNMPv3, and RMON 1 and 2 Third Edition by William Stallings

I have started reading this book on SNMP by William Stallings recently. I have read just 6 of 17 chapters till now. What i wanted was a complete but simplified (than RFC's) write up on SNMP protocol and some of the standard MIBs. I have worked in SNMP for almost 7 yrs now and whatever i learnt was on-the-job. So i needed one book which puts together the different pieces of information pertaining to SNMP-based network management in a coherent form. Much of what i read in this book is what i already knew but reading it from a book gives a different perspective. Like for eg, sysUpTime can be used to deduce if the agent has been restarted since the last poll or that the ifAdminStatus reflects the value set by management station to change the operational state of the interface but ifOperStatus reflects the current operational status (and is RO). So if ifAdminStatus is up(1) and ifOperStatus is down(2) then the interface has failed can be concluded. And so on.. Another book which i am p…
